+# Debugging
+
+## Root cause first
+
+When encountering a bug, investigate the root cause. Don't patch symptoms. If you're about to add a try/except, a fallback default, or a defensive check — ask whether the real fix is upstream.
+
+## Isolated testing
+
+Prefer running individual test functions over full suites. Only run the full suite when explicitly asked or before pushing.
+
+- Single function: `uv run pytest tests/test_foo.py::TestBar::test_baz -v`
+- Single module: `uv run pytest tests/test_foo.py -v`
+- Full suite: only when asked, or before `git push`
+
+When debugging a specific endpoint or integration, test it directly instead of running the entire pipeline end-to-end.
+
+## Subprocess failures
+
+When a subprocess fails, always log stdout and stderr. "Exit code 1" with no output is useless.

 - Never commit, amend, or push without explicit permission
-- Don't commit intermediate states — wait until the full implementation is complete, reviewed, and explicitly approved before committing. If the user corrects direction mid-implementation, incorporate the correction before any commit
-- Always create a new branch from `main` before starting any new work — never commit directly to `main` or reuse an existing feature branch for unrelated changes
-- Use conventional commit format: `fix:`, `feat:`, `refactor:`, `docs:`, `test:`, `chore:`
-- Keep commits atomic - one logical change per commit
-- Commit message body should be concise (1-2 sentences max)
-- Merge for simple syncs, rebase when branches have diverged significantly
-- When committing to an external/third-party repo, follow that repo's own conventions for versioning, changelog, and CI
-- Pre-commit: Run `uv run prek` before committing — fix any issues before creating the commit
-- Pre-push: Run `uv run prek run --from-ref origin/<base>` to check all changed files against the PR base — this matches CI behavior and catches issues that per-commit prek misses. To detect the base branch: `gh pr view --json baseRefName -q .baseRefName 2>/dev/null || echo main`

+# Session Discipline
+
+## Scope
+
+One task per session. Don't mix implementation with communication drafting, transcript search, or strategic planning.
+
+## Duration
+
+Cap sessions at 2-3 hours. Use `/handoff` at natural breakpoints rather than letting auto-compaction degrade context.
+
+- After 1 compaction: consider wrapping up the current task and handing off
+- After 3 compactions: stop, and tell the user to start a fresh session
+- Never continue past 5 compactions — context is too degraded
+
+## Context preservation
+
+When compacting, preserve: modified files list, current branch, test commands used, key decisions made. Use subagents for exploration to keep main context clean.
+
+## No polling
+
+Never poll background tasks. No `wc -l`, no `tail -f`, no `sleep` loops. Use `run_in_background` and wait for the completion notification.
+
+## File read budget
+
+If you've read the same file 3+ times in a session, either:
+- The session is too long and compaction destroyed your context — write a handoff
+- You're not retaining key information — write it down in your response before it compacts away

+# Annotations
+
+Gson provides several annotations to control serialization and deserialization behavior directly on fields and classes without requiring configuration changes.
+
+## @SerializedName
+
+Specifies alternative names for fields during serialization and deserialization.
+
+```java { .api }
+@Target({ElementType.FIELD, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+public @interface SerializedName {
+    String value();
+    String[] alternate() default {};
+}
+```
+
+**Basic usage:**
+```java
+public class Person {
+    @SerializedName("full_name")
+    private String name;
+    
+    @SerializedName("years_old")
+    private int age;
+}
+
+// JSON: {"full_name":"Alice","years_old":30}
+```
+
+**Multiple alternative names for deserialization:**
+```java
+public class Person {
+    @SerializedName(value = "name", alternate = {"full_name", "firstName", "first_name"})
+    private String name;
+}
+
+// Can deserialize from any of these JSON formats:
+// {"name":"Alice"}
+// {"full_name":"Alice"}  
+// {"firstName":"Alice"}
+// {"first_name":"Alice"}
+```
+
+## @Expose
+
+Controls which fields are included in serialization and deserialization when using `excludeFieldsWithoutExposeAnnotation()`.
+
+```java { .api }
+@Target(ElementType.FIELD)
+@Retention(RetentionPolicy.RUNTIME)
+public @interface Expose {
+    boolean serialize() default true;
+    boolean deserialize() default true;
+}
+```
+
+**Usage:**
+```java
+public class User {
+    @Expose
+    private String name;
+    
+    @Expose(serialize = false) // Only for deserialization
+    private String password;
+    
+    @Expose(deserialize = false) // Only for serialization
+    private String token;
+    
+    private String internalId; // Not exposed
+}
+
+Gson gson = new GsonBuilder()
+    .excludeFieldsWithoutExposeAnnotation()
+    .create();
+
+// Only fields marked with @Expose will be processed
+```
+
+## @Since
+
+Marks fields as available since a specific API version.
+
+```java { .api }
+@Target({ElementType.FIELD, ElementType.TYPE})
+@Retention(RetentionPolicy.RUNTIME)
+public @interface Since {
+    double value();
+}
+```
+
+**Usage:**
+```java
+public class ApiResponse {
+    private String status;
+    
+    @Since(1.1)
+    private String message;
+    
+    @Since(2.0)
+    private List<String> errors;
+}
+
+// Only include fields from version 1.1 and later
+Gson gson = new GsonBuilder()
+    .setVersion(1.1)
+    .create();
+
+// 'status' and 'message' will be included, but 'errors' will be excluded
+```
+
+## @Until
+
+Marks fields as available until a specific API version.
+
+```java { .api }
+@Target({ElementType.FIELD, ElementType.TYPE})
+@Retention(RetentionPolicy.RUNTIME)
+public @interface Until {
+    double value();
+}
+```
+
+**Usage:**
+```java
+public class LegacyResponse {
+    private String data;
+    
+    @Until(2.0)
+    private String oldFormat; // Deprecated in version 2.0
+    
+    @Since(2.0)
+    private String newFormat; // Added in version 2.0
+}
+
+// Version 1.5: includes 'data' and 'oldFormat'
+Gson gson15 = new GsonBuilder().setVersion(1.5).create();
+
+// Version 2.1: includes 'data' and 'newFormat'
+Gson gson21 = new GsonBuilder().setVersion(2.1).create();
+```
+
+## @JsonAdapter
+
+Specifies a custom TypeAdapter, JsonSerializer, JsonDeserializer, or TypeAdapterFactory for a field or class.
+
+```java { .api }
+@Target({ElementType.TYPE, ElementType.FIELD})
+@Retention(RetentionPolicy.RUNTIME)
+public @interface JsonAdapter {
+    Class<?> value();
+    boolean nullSafe() default true;
+}
+```
+
+**Field-level adapter:**
+```java
+public class Event {
+    private String name;
+    
+    @JsonAdapter(DateAdapter.class)
+    private Date timestamp;
+}
+
+public class DateAdapter extends TypeAdapter<Date> {
+    private final DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
+    
+    @Override
+    public void write(JsonWriter out, Date date) throws IOException {
+        if (date == null) {
+            out.nullValue();
+        } else {
+            out.value(format.format(date));
+        }
+    }
+    
+    @Override
+    public Date read(JsonReader in) throws IOException {
+        if (in.peek() == JsonToken.NULL) {
+            in.nextNull();
+            return null;
+        }
+        try {
+            return format.parse(in.nextString());
+        } catch (ParseException e) {
+            throw new IOException(e);
+        }
+    }
+}
+```
+
+**Class-level adapter:**
+```java
+@JsonAdapter(ColorAdapter.class)
+public class Color {
+    private int red, green, blue;
+    
+    public Color(int red, int green, int blue) {
+        this.red = red;
+        this.green = green;
+        this.blue = blue;
+    }
+}
+
+public class ColorAdapter extends TypeAdapter<Color> {
+    @Override
+    public void write(JsonWriter out, Color color) throws IOException {
+        if (color == null) {
+            out.nullValue();
+        } else {
+            String hex = String.format("#%02x%02x%02x", color.red, color.green, color.blue);
+            out.value(hex);
+        }
+    }
+    
+    @Override
+    public Color read(JsonReader in) throws IOException {
+        if (in.peek() == JsonToken.NULL) {
+            in.nextNull();
+            return null;
+        }
+        
+        String hex = in.nextString();
+        if (hex.startsWith("#")) {
+            hex = hex.substring(1);
+        }
+        
+        int rgb = Integer.parseInt(hex, 16);
+        return new Color((rgb >> 16) & 0xFF, (rgb >> 8) & 0xFF, rgb & 0xFF);
+    }
+}
+
+// Usage: Color serializes as "#ff0000" instead of {"red":255,"green":0,"blue":0}
+```
+
+**Using with JsonSerializer/JsonDeserializer:**
+```java
+public class User {
+    private String name;
+    
+    @JsonAdapter(PasswordSerializer.class)
+    private String password;
+}
+
+public class PasswordSerializer implements JsonSerializer<String>, JsonDeserializer<String> {
+    @Override
+    public JsonElement serialize(String src, Type typeOfSrc, JsonSerializationContext context) {
+        return new JsonPrimitive("***"); // Always serialize as stars
+    }
+    
+    @Override
+    public String deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) {
+        return json.getAsString(); // Deserialize normally
+    }
+}
+```
+
+**Using with TypeAdapterFactory:**
+```java
+@JsonAdapter(CaseInsensitiveEnumAdapterFactory.class)
+public enum Status {
+    ACTIVE, INACTIVE, PENDING
+}
+
+public class CaseInsensitiveEnumAdapterFactory implements TypeAdapterFactory {
+    @Override
+    @SuppressWarnings("unchecked")
+    public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> type) {
+        Class<T> rawType = (Class<T>) type.getRawType();
+        if (!rawType.isEnum()) {
+            return null;
+        }
+        
+        return new TypeAdapter<T>() {
+            @Override
+            public void write(JsonWriter out, T value) throws IOException {
+                if (value == null) {
+                    out.nullValue();
+                } else {
+                    out.value(value.toString());
+                }
+            }
+            
+            @Override
+            @SuppressWarnings("unchecked")
+            public T read(JsonReader in) throws IOException {
+                if (in.peek() == JsonToken.NULL) {
+                    in.nextNull();
+                    return null;
+                }
+                
+                String value = in.nextString().toUpperCase();
+                return (T) Enum.valueOf((Class<Enum>) rawType, value);
+            }
+        };
+    }
+}
+```
+
+## Combining Annotations
+
+Annotations can be combined for comprehensive control:
+
+```java
+public class Product {
+    @SerializedName("product_id")
+    @Since(1.0)
+    private String id;
+    
+    @SerializedName("product_name")
+    @Expose
+    private String name;
+    
+    @SerializedName("price_cents")
+    @JsonAdapter(MoneyAdapter.class)
+    private Money price;
+    
+    @Until(2.0)
+    private String oldCategory;
+    
+    @Since(2.0)
+    @SerializedName("category_info")
+    private Category category;
+    
+    @Expose(serialize = false)
+    private String internalNotes;
+}
+```
+
+## Annotation Processing Order
+
+Gson processes annotations in the following priority:
+
+1. **@JsonAdapter** - Takes highest precedence
+2. **@SerializedName** - Controls field naming
+3. **@Expose** - Controls field inclusion (when enabled)
+4. **@Since/@Until** - Controls version-based inclusion
+5. **Field modifiers** - Processed based on GsonBuilder configuration
+
+**Example:**
+```java
+public class Example {
+    @JsonAdapter(CustomAdapter.class)  // 1. Custom adapter used
+    @SerializedName("custom_field")    // 2. Field name in JSON
+    @Expose(serialize = false)         // 3. Only deserialize (if expose filtering enabled)
+    @Since(1.1)                        // 4. Only if version >= 1.1
+    private String field;
+}
+```
+
+## Best Practices
+
+**Use @SerializedName for API compatibility:**
+```java
+public class ApiModel {
+    @SerializedName("user_id")
+    private String userId;  // Java convention: camelCase
+    
+    @SerializedName("created_at")
+    private Date createdAt; // API uses snake_case
+}
+```
+
+**Use @Expose for security:**
+```java
+public class User {
+    @Expose
+    private String username;
+    
+    @Expose
+    private String email;
+    
+    private String passwordHash; // Never expose sensitive data
+    
+    @Expose(serialize = false)
+    private String password; // Accept for input, never output
+}
+```
+
+**Use versioning for API evolution:**
+```java
+public class ApiResponse {
+    private String status;
+    
+    @Until(1.9)
+    private String oldErrorMessage;
+    
+    @Since(2.0)
+    private ErrorDetails errorDetails;
+}
+```
+
+**Use @JsonAdapter for domain-specific serialization:**
+```java
+public class Order {
+    @JsonAdapter(CurrencyAdapter.class)
+    private BigDecimal totalAmount;
+    
+    @JsonAdapter(TimestampAdapter.class)
+    private Instant orderTime;
+    
+    @JsonAdapter(Base64Adapter.class)
+    private byte[] signature;
+}
+```

+# Configuration
+
+Gson provides extensive configuration options through the GsonBuilder class for customizing serialization and deserialization behavior.
+
+## GsonBuilder
+
+Builder pattern class for configuring Gson instances.
+
+```java { .api }
+public final class GsonBuilder {
+    public GsonBuilder();
+    
+    // JSON formatting
+    public GsonBuilder setPrettyPrinting();
+    public GsonBuilder setFormattingStyle(FormattingStyle formattingStyle);
+    public GsonBuilder disableHtmlEscaping();

+    // Field naming
+    public GsonBuilder setFieldNamingPolicy(FieldNamingPolicy namingConvention);
+    public GsonBuilder setFieldNamingStrategy(FieldNamingStrategy fieldNamingStrategy);
+    
+    // Version control
+    public GsonBuilder setVersion(double version);

+    
+    // Date formatting
+    public GsonBuilder setDateFormat(String pattern);
+    public GsonBuilder setDateFormat(int dateStyle);
+    public GsonBuilder setDateFormat(int dateStyle, int timeStyle);
+    
+    // JSON parsing strictness
+    public GsonBuilder setLenient();
+    public GsonBuilder setStrictness(Strictness strictness);
+    
+    // Advanced options
+    public GsonBuilder enableComplexMapKeySerialization();
+    public GsonBuilder disableInnerClassSerialization();
+    public GsonBuilder generateNonExecutableJson();
+    public GsonBuilder disableJdkUnsafe();
+    public GsonBuilder addReflectionAccessFilter(ReflectionAccessFilter filter);
+    
+    // Build final instance
+    public Gson create();
+}
+```
+
+## Basic Configuration
+
+**Creating a configured Gson instance:**
+```java
+Gson gson = new GsonBuilder()
+    .setPrettyPrinting()
+    .serializeNulls()
+    .create();
+```
+
+## Field Naming Policies
+
+Control how Java field names are converted to JSON property names.
+
+```java { .api }
+public enum FieldNamingPolicy implements FieldNamingStrategy {
+    IDENTITY,
+    UPPER_CAMEL_CASE,
+    UPPER_CAMEL_CASE_WITH_SPACES,
+    UPPER_CASE_WITH_UNDERSCORES,
+    LOWER_CASE_WITH_UNDERSCORES,
+    LOWER_CASE_WITH_DASHES,
+    LOWER_CASE_WITH_DOTS
+}
+```
+
+**Usage:**
+```java
+Gson gson = new GsonBuilder()
+    .setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)
+    .create();
+
+class Person {
+    String firstName; // becomes "first_name" in JSON
+    String lastName;  // becomes "last_name" in JSON
+}
+```
+
+## Custom Field Naming Strategy
+
+```java { .api }
+public interface FieldNamingStrategy {
+    public String translateName(Field f);
+}
+```
+
+**Usage:**
+```java
+FieldNamingStrategy customStrategy = field -> {
+    return "prefix_" + field.getName().toLowerCase();
+};
+
+Gson gson = new GsonBuilder()
+    .setFieldNamingStrategy(customStrategy)
+    .create();
+```
+
+## Exclusion Strategies
+
+Control which fields and classes are included in serialization/deserialization.
+
+```java { .api }
+public interface ExclusionStrategy {
+    public boolean shouldSkipField(FieldAttributes f);
+    public boolean shouldSkipClass(Class<?> clazz);
+}
+```
+
+**Usage:**
+```java
+ExclusionStrategy strategy = new ExclusionStrategy() {
+    @Override
+    public boolean shouldSkipField(FieldAttributes f) {
+        return f.getName().startsWith("internal");
+    }
+    
+    @Override
+    public boolean shouldSkipClass(Class<?> clazz) {
+        return clazz.getName().contains("Internal");
+    }
+};
+
+Gson gson = new GsonBuilder()
+    .setExclusionStrategies(strategy)
+    .create();
+```
+
+## Field Attributes
+
+Information about fields for exclusion strategies.
+
+```java { .api }
+public final class FieldAttributes {
+    public Class<?> getDeclaringClass();
+    public String getName();
+    public Type getDeclaredType();
+    public Class<?> getDeclaredClass();
+    public <T extends Annotation> T getAnnotation(Class<T> annotation);
+    public Collection<Annotation> getAnnotations();
+    public boolean hasModifier(int modifier);
+}
+```
+
+## Number Handling
+
+### Long Serialization Policy
+
+```java { .api }
+public enum LongSerializationPolicy {
+    DEFAULT,  // Serialize as numbers
+    STRING    // Serialize as strings
+}
+```
+
+**Usage:**
+```java
+Gson gson = new GsonBuilder()
+    .setLongSerializationPolicy(LongSerializationPolicy.STRING)
+    .create();
+```
+
+### Number Strategies
+
+```java { .api }
+public interface ToNumberStrategy {
+    public Number readNumber(JsonReader in) throws IOException;
+}
+
+public enum ToNumberPolicy implements ToNumberStrategy {
+    DOUBLE,
+    LAZILY_PARSED_NUMBER,
+    LONG_OR_DOUBLE,
+    BIG_DECIMAL
+}
+```
+
+**Usage:**
+```java
+Gson gson = new GsonBuilder()
+    .setObjectToNumberStrategy(ToNumberPolicy.BIG_DECIMAL)
+    .setNumberToNumberStrategy(ToNumberPolicy.BIG_DECIMAL)
+    .create();
+```
+
+## Date Formatting
+
+**Pattern-based formatting:**
+```java
+Gson gson = new GsonBuilder()
+    .setDateFormat("yyyy-MM-dd HH:mm:ss")
+    .create();
+```
+
+**Style-based formatting:**
+```java
+import java.text.DateFormat;
+
+Gson gson = new GsonBuilder()
+    .setDateFormat(DateFormat.LONG)
+    .create();
+
+// Or with both date and time styles
+Gson gson = new GsonBuilder()
+    .setDateFormat(DateFormat.MEDIUM, DateFormat.SHORT)
+    .create();
+```
+
+## JSON Formatting
+
+### Pretty Printing
+
+```java
+Gson gson = new GsonBuilder()
+    .setPrettyPrinting()
+    .create();
+```
+
+### Custom Formatting Style
+
+```java { .api }
+public class FormattingStyle {
+    public static FormattingStyle COMPACT;
+    public static FormattingStyle PRETTY;
+    
+    public FormattingStyle withNewline(String newline);
+    public FormattingStyle withIndent(String indent);
+    public FormattingStyle withSpaceAfterSeparators(boolean spaceAfterSeparators);
+}
+```
+
+**Usage:**
+```java
+FormattingStyle style = FormattingStyle.PRETTY
+    .withIndent("    ")  // 4 spaces
+    .withNewline("\n");
+
+Gson gson = new GsonBuilder()
+    .setFormattingStyle(style)
+    .create();
+```
+
+## Strictness Control
+
+```java { .api }
+public enum Strictness {
+    LENIENT,  // Allows malformed JSON
+    STRICT    // Requires well-formed JSON
+}
+```
+
+**Usage:**
+```java
+// Lenient parsing (allows single quotes, unquoted names, etc.)
+Gson gson = new GsonBuilder()
+    .setLenient()
+    .create();
+
+// Or explicitly set strictness
+Gson gson = new GsonBuilder()
+    .setStrictness(Strictness.LENIENT)
+    .create();
+```
+
+## Advanced Configuration
+
+### Complex Map Keys
+
+Enable serialization of complex objects as map keys:
+```java
+Gson gson = new GsonBuilder()
+    .enableComplexMapKeySerialization()
+    .create();
+```
+
+### HTML Escaping
+
+Disable HTML character escaping:
+```java
+Gson gson = new GsonBuilder()
+    .disableHtmlEscaping()
+    .create();
+```
+
+### Reflection Access Control
+
+```java { .api }
+public interface ReflectionAccessFilter {
+    enum FilterResult { ALLOW, BLOCK_INACCESSIBLE, BLOCK_ALL }
+    
+    FilterResult check(Class<?> rawClass);
+}
+```
+
+**Usage:**
+```java
+ReflectionAccessFilter filter = new ReflectionAccessFilter() {
+    @Override
+    public FilterResult check(Class<?> rawClass) {
+        if (rawClass.getPackage().getName().startsWith("com.example.internal")) {
+            return FilterResult.BLOCK_ALL;
+        }
+        return FilterResult.ALLOW;
+    }
+};
+
+Gson gson = new GsonBuilder()
+    .addReflectionAccessFilter(filter)
+    .create();
+```
+
+### Version Control
+
+Use `@Since` and `@Until` annotations with version setting:
+```java
+Gson gson = new GsonBuilder()
+    .setVersion(2.0)
+    .create();
+```
+
+### Modifier-based Exclusion
+
+Exclude fields based on Java modifiers:

+# Gson
+
+Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code access to.
+
+## Package Information
+
+- **Package Name**: com.google.code.gson:gson
+- **Package Type**: Maven
+- **Language**: Java
+- **Installation**: 
+  ```xml
+  <dependency>
+    <groupId>com.google.code.gson</groupId>
+    <artifactId>gson</artifactId>
+    <version>2.13.1</version>
+  </dependency>
+  ```
+
+## Core Imports
+
+```java
+import com.google.gson.Gson;
+import com.google.gson.GsonBuilder;
+```
+
+For JSON tree model:
+```java
+import com.google.gson.JsonElement;
+import com.google.gson.JsonObject;
+import com.google.gson.JsonArray;
+import com.google.gson.JsonPrimitive;
+```
+
+For streaming:
+```java
+import com.google.gson.stream.JsonReader;
+import com.google.gson.stream.JsonWriter;
+```
+
+## Basic Usage
+
+```java
+import com.google.gson.Gson;
+
+// Simple object serialization
+class Person {
+    private String name;
+    private int age;
+    
+    public Person(String name, int age) {
+        this.name = name;
+        this.age = age;
+    }
+}
+
+// Create Gson instance
+Gson gson = new Gson();
+
+// Convert Java object to JSON
+Person person = new Person("John", 30);
+String json = gson.toJson(person);
+// Result: {"name":"John","age":30}
+
+// Convert JSON to Java object
+String jsonString = "{\"name\":\"Jane\",\"age\":25}";
+Person deserializedPerson = gson.fromJson(jsonString, Person.class);
+```
+
+## Architecture
+
+Gson is built around several key components:
+
+- **Gson Class**: Main entry point providing `toJson()` and `fromJson()` methods
+- **GsonBuilder**: Builder pattern for configuring Gson instances with custom settings
+- **JSON Tree Model**: Object representation (JsonElement hierarchy) for manipulating JSON as trees
+- **Streaming API**: Memory-efficient reading/writing for large JSON documents
+- **Type Adapters**: Pluggable serialization/deserialization for custom types
+- **Reflection System**: Automatic object mapping using Java reflection
+
+## Capabilities
+
+### Object Serialization and Deserialization
+
+Core functionality for converting between Java objects and JSON strings. Handles arbitrarily complex objects with deep inheritance hierarchies and generic types.
+
+```java { .api }
+public String toJson(Object src);
+public String toJson(Object src, Type typeOfSrc);
+public <T> T fromJson(String json, Class<T> classOfT);
+public <T> T fromJson(String json, Type typeOfT);
+public <T> T fromJson(String json, TypeToken<T> typeOfT);
+```
+
+[Object Serialization](./object-serialization.md)
+
+### JSON Tree Model
+
+Tree-based API for building and manipulating JSON structures programmatically. Useful when you need to modify JSON before serialization or after deserialization.
+
+```java { .api }
+public JsonElement toJsonTree(Object src);
+public <T> T fromJson(JsonElement json, Class<T> classOfT);
+
+abstract class JsonElement {
+    public boolean isJsonObject();
+    public boolean isJsonArray();
+    public boolean isJsonPrimitive();
+    public boolean isJsonNull();
+}
+```
+
+[JSON Tree Model](./json-tree-model.md)
+
+### Configuration and Customization
+
+Extensive configuration options for controlling serialization behavior, field naming, date formatting, and custom type adapters.
+
+```java { .api }
+public final class GsonBuilder {
+    public GsonBuilder setPrettyPrinting();
+    public GsonBuilder serializeNulls();
+    public GsonBuilder setFieldNamingPolicy(FieldNamingPolicy namingConvention);
+    public GsonBuilder registerTypeAdapter(Type type, Object typeAdapter);
+    public Gson create();
+}
+```
+
+[Configuration](./configuration.md)
+
+### Streaming API
+
+Memory-efficient streaming API for processing large JSON documents without loading them entirely into memory.
+
+```java { .api }
+public class JsonReader implements Closeable {
+    public JsonToken peek() throws IOException;
+    public String nextString() throws IOException;
+    public int nextInt() throws IOException;
+    public void beginObject() throws IOException;
+    public void endObject() throws IOException;
+}
+
+public class JsonWriter implements Closeable, Flushable {
+    public JsonWriter name(String name) throws IOException;
+    public JsonWriter value(String value) throws IOException;
+    public JsonWriter beginObject() throws IOException;
+    public JsonWriter endObject() throws IOException;
+}
+```
+
+[Streaming API](./streaming-api.md)
+
+### Type Adapters
+
+Pluggable system for custom serialization and deserialization logic. Allows fine-grained control over how specific types are converted.
+
+```java { .api }
+public abstract class TypeAdapter<T> {
+    public abstract void write(JsonWriter out, T value) throws IOException;
+    public abstract T read(JsonReader in) throws IOException;
+}
+
+public interface TypeAdapterFactory {
+    public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> type);
+}
+```
+
+[Type Adapters](./type-adapters.md)
+
+### Annotations
+
+Annotations for controlling serialization behavior on fields and classes without requiring configuration changes.
+
+```java { .api }
+@SerializedName("custom_name")
+@Expose(serialize = true, deserialize = true)
+@Since(1.0)
+@Until(2.0)
+@JsonAdapter(CustomAdapter.class)
+```
+
+[Annotations](./annotations.md)
+
+## Types
+
+```java { .api }
+// Core exception types
+class JsonParseException extends RuntimeException {}
+class JsonSyntaxException extends JsonParseException {}
+class JsonIOException extends JsonParseException {}
+
+// Enums for configuration
+enum FieldNamingPolicy {
+    IDENTITY, UPPER_CAMEL_CASE, UPPER_CAMEL_CASE_WITH_SPACES,
+    UPPER_CASE_WITH_UNDERSCORES, LOWER_CASE_WITH_UNDERSCORES,
+    LOWER_CASE_WITH_DASHES, LOWER_CASE_WITH_DOTS
+}
+
+enum LongSerializationPolicy { DEFAULT, STRING }
+
+enum ToNumberPolicy implements ToNumberStrategy {
+    DOUBLE, LAZILY_PARSED_NUMBER, LONG_OR_DOUBLE, BIG_DECIMAL
+}
+
+// Type handling

+
+// Tree back to object
+Person modifiedPerson = gson.fromJson(obj, Person.class);
+
+// Tree to JSON string
+String json = gson.toJson(tree);
+```
+
+## JsonParser
+
+Utility for parsing JSON strings into JsonElement trees.
+
+```java { .api }
+public final class JsonParser {
+    public static JsonElement parseString(String json) throws JsonSyntaxException;
+    public static JsonElement parseReader(Reader reader) throws JsonIOException, JsonSyntaxException;
+    public static JsonElement parseReader(JsonReader reader) throws JsonIOException, JsonSyntaxException;
+}
+```
+
+**Usage:**
+```java
+String json = "{\"name\":\"Alice\",\"age\":30}";
+JsonElement element = JsonParser.parseString(json);
+
+if (element.isJsonObject()) {
+    JsonObject obj = element.getAsJsonObject();
+    String name = obj.get("name").getAsString();
+}
+```
+
+## JsonStreamParser
+
+Streaming parser for processing multiple JSON values from a single reader.
+
+```java { .api }
+public final class JsonStreamParser implements Iterator<JsonElement> {
+    public JsonStreamParser(Reader reader);
+    public JsonStreamParser(String json);
+    
+    public boolean hasNext();
+    public JsonElement next() throws JsonParseException;
+}
+```
+
+**Usage:**
+```java
+String multipleJson = "{\"name\":\"Alice\"} {\"name\":\"Bob\"} [1,2,3]";
+JsonStreamParser parser = new JsonStreamParser(multipleJson);
+
+while (parser.hasNext()) {
+    JsonElement element = parser.next();
+    System.out.println(element);
+}
+```
+
+## Complex Tree Manipulation
+
+**Building nested structures:**
+```java
+JsonObject address = new JsonObject();
+address.addProperty("street", "123 Main St");
+address.addProperty("city", "Springfield");
+
+JsonObject person = new JsonObject();
+person.addProperty("name", "John");
+person.add("address", address);
+
+JsonArray hobbies = new JsonArray();
+hobbies.add("reading");
+hobbies.add("swimming");
+person.add("hobbies", hobbies);
+```
+
+**Traversing complex structures:**
+```java
+JsonObject root = JsonParser.parseString(complexJson).getAsJsonObject();
+
+for (Map.Entry<String, JsonElement> entry : root.entrySet()) {
+    String key = entry.getKey();
+    JsonElement value = entry.getValue();
+    
+    if (value.isJsonObject()) {
+        JsonObject nested = value.getAsJsonObject();
+        // Process nested object
+    } else if (value.isJsonArray()) {
+        JsonArray array = value.getAsJsonArray();
+        for (JsonElement item : array) {
+            // Process array item
+        }
+    }
+}

+# Object Serialization
+
+The core functionality of Gson for converting between Java objects and JSON strings.
+
+## Serialization (Java to JSON)
+
+### Basic Serialization
+
+```java { .api }
+public String toJson(Object src);
+```
+
+Converts any Java object to its JSON string representation using default settings.
+
+**Usage:**
+```java
+Gson gson = new Gson();
+Person person = new Person("Alice", 30);
+String json = gson.toJson(person);
+// Result: {"name":"Alice","age":30}
+```
+
+### Serialization with Type Information
+
+```java { .api }
+public String toJson(Object src, Type typeOfSrc);
+```
+
+Explicitly specifies the type for serialization, useful for generic collections and inheritance hierarchies.
+
+**Usage:**
+```java
+List<String> names = Arrays.asList("Alice", "Bob", "Charlie");
+Type listType = new TypeToken<List<String>>(){}.getType();
+String json = gson.toJson(names, listType);
+// Result: ["Alice","Bob","Charlie"]
+```
+
+### Serialization to Writer
+
+```java { .api }
+public void toJson(Object src, Appendable writer) throws JsonIOException;
+public void toJson(Object src, Type typeOfSrc, Appendable writer) throws JsonIOException;
+public void toJson(Object src, Type typeOfSrc, JsonWriter writer) throws JsonIOException;
+```
+
+Serialize directly to a Writer or JsonWriter for memory efficiency or streaming output.
+
+**Usage:**
+```java
+StringWriter writer = new StringWriter();
+gson.toJson(person, writer);
+String json = writer.toString();
+```
+
+## Deserialization (JSON to Java)
+
+### Basic Deserialization
+
+```java { .api }
+public <T> T fromJson(String json, Class<T> classOfT) throws JsonSyntaxException;
+```
+
+Converts JSON string to Java object of the specified class.
+
+**Usage:**
+```java
+String json = "{\"name\":\"Bob\",\"age\":25}";
+Person person = gson.fromJson(json, Person.class);
+```
+
+### Deserialization with Generic Types
+
+```java { .api }
+public <T> T fromJson(String json, Type typeOfT) throws JsonSyntaxException;
+public <T> T fromJson(String json, TypeToken<T> typeOfT) throws JsonSyntaxException;
+```
+
+Handles generic types like collections and maps using Type or TypeToken.
+
+**Usage:**
+```java
+String json = "[\"Alice\",\"Bob\",\"Charlie\"]";
+Type listType = new TypeToken<List<String>>(){}.getType();
+List<String> names = gson.fromJson(json, listType);
+
+// Or using TypeToken directly
+TypeToken<List<String>> token = new TypeToken<List<String>>(){};
+List<String> names = gson.fromJson(json, token);
+```
+
+### Deserialization from Reader
+
+```java { .api }
+public <T> T fromJson(Reader json, Class<T> classOfT) throws JsonIOException, JsonSyntaxException;
+public <T> T fromJson(Reader json, Type typeOfT) throws JsonIOException, JsonSyntaxException;
+public <T> T fromJson(Reader json, TypeToken<T> typeOfT) throws JsonIOException, JsonSyntaxException;
+```
+
+Deserialize from a Reader for memory-efficient processing of large files.
+
+**Usage:**
+```java
+FileReader reader = new FileReader("data.json");
+Person person = gson.fromJson(reader, Person.class);
+reader.close();
+```
+
+### Deserialization from JsonReader
+
+```java { .api }
+public <T> T fromJson(JsonReader reader, Type typeOfT) throws JsonIOException, JsonSyntaxException;
+public <T> T fromJson(JsonReader reader, TypeToken<T> typeOfT) throws JsonIOException, JsonSyntaxException;
+```
+
+Deserialize from JsonReader for streaming API integration.
+
+**Usage:**
+```java
+JsonReader reader = new JsonReader(new StringReader(json));
+Person person = gson.fromJson(reader, Person.class);
+reader.close();
+```
+
+## Complex Object Handling
+
+### Collections
+
+Gson automatically handles standard Java collections:
+
+```java
+// Lists
+List<String> list = Arrays.asList("a", "b", "c");
+String json = gson.toJson(list);
+List<String> restored = gson.fromJson(json, new TypeToken<List<String>>(){}.getType());
+
+// Maps
+Map<String, Integer> map = new HashMap<>();
+map.put("one", 1);
+map.put("two", 2);
+String json = gson.toJson(map);
+Map<String, Integer> restored = gson.fromJson(json, new TypeToken<Map<String, Integer>>(){}.getType());
+```
+
+### Arrays
+
+```java
+int[] numbers = {1, 2, 3, 4, 5};
+String json = gson.toJson(numbers);
+int[] restored = gson.fromJson(json, int[].class);
+```
+
+### Nested Objects
+
+```java
+class Address {
+    String street;
+    String city;
+}
+
+class Person {
+    String name;
+    Address address;
+}
+
+Person person = new Person();
+person.name = "John";
+person.address = new Address();
+person.address.street = "123 Main St";
+person.address.city = "Springfield";
+
+String json = gson.toJson(person);
+Person restored = gson.fromJson(json, Person.class);
+```
+
+### Inheritance
+
+```java
+class Animal {
+    String name;
+}
+
+class Dog extends Animal {
+    String breed;
+}
+
+Dog dog = new Dog();
+dog.name = "Buddy";
+dog.breed = "Golden Retriever";
+
+// Serialize as Dog type
+String json = gson.toJson(dog, Dog.class);
+Dog restored = gson.fromJson(json, Dog.class);
+```
+
+## Error Handling
+
+```java { .api }
+class JsonSyntaxException extends JsonParseException {
+    // Thrown when JSON syntax is invalid
+}
+
+class JsonIOException extends JsonParseException {
+    // Thrown when I/O errors occur during reading/writing
+}
+```
+
+**Usage:**
+```java
+try {
+    Person person = gson.fromJson(invalidJson, Person.class);
+} catch (JsonSyntaxException e) {
+    System.err.println("Invalid JSON syntax: " + e.getMessage());
+} catch (JsonIOException e) {
+    System.err.println("I/O error: " + e.getMessage());
+}
+```

+# Streaming API
+
+Gson's streaming API provides memory-efficient processing of JSON data through JsonReader and JsonWriter classes. This is essential for handling large JSON documents without loading them entirely into memory.
+
+## JsonReader
+
+Read JSON content in a streaming fashion.
+
+```java { .api }
+public class JsonReader implements Closeable {
+    public JsonReader(Reader in);
+    
+    // Configuration
+    public void setLenient(boolean lenient);
+    public boolean isLenient();
+    public void setStrictness(Strictness strictness);
+    public Strictness getStrictness();
+    
+    // Navigation
+    public JsonToken peek() throws IOException;
+    public JsonToken nextToken() throws IOException;
+    public void skipValue() throws IOException;
+    
+    // Object navigation
+    public void beginObject() throws IOException;
+    public void endObject() throws IOException;
+    public String nextName() throws IOException;
+    
+    // Array navigation
+    public void beginArray() throws IOException;
+    public void endArray() throws IOException;
+    
+    // Value reading
+    public String nextString() throws IOException;
+    public boolean nextBoolean() throws IOException;
+    public void nextNull() throws IOException;
+    public double nextDouble() throws IOException;
+    public long nextLong() throws IOException;
+    public int nextInt() throws IOException;
+    
+    // State
+    public boolean hasNext() throws IOException;
+    public String getPath();
+    
+    // Resource management
+    public void close() throws IOException;
+}
+```
+
+### JsonToken Enum
+
+```java { .api }
+public enum JsonToken {
+    BEGIN_ARRAY,
+    END_ARRAY,
+    BEGIN_OBJECT,
+    END_OBJECT,
+    NAME,
+    STRING,
+    NUMBER,
+    BOOLEAN,
+    NULL,
+    END_DOCUMENT
+}
+```
+
+**Reading JSON objects:**
+```java
+String json = "{\"name\":\"Alice\",\"age\":30,\"active\":true}";
+JsonReader reader = new JsonReader(new StringReader(json));
+
+reader.beginObject();
+while (reader.hasNext()) {
+    String name = reader.nextName();
+    switch (name) {
+        case "name":

+            break;
+        default:
+            reader.skipValue(); // Skip unknown properties
+            break;
+    }
+}
+reader.endObject();
+reader.close();
+```
+
+**Reading JSON arrays:**
+```java
+String json = "[1,2,3,4,5]";
+JsonReader reader = new JsonReader(new StringReader(json));
+
+reader.beginArray();
+while (reader.hasNext()) {
+    int value = reader.nextInt();
+    System.out.println(value);
+}
+reader.endArray();
+reader.close();
+```
+
+**Reading complex nested structures:**
+```java
+String json = "{\"users\":[{\"name\":\"Alice\",\"age\":30},{\"name\":\"Bob\",\"age\":25}]}";
+JsonReader reader = new JsonReader(new StringReader(json));
+
+reader.beginObject();

+    } else {
+        reader.skipValue();
+    }
+}
+reader.endObject();
+reader.close();
+```
+
+## JsonWriter
+
+Write JSON content in a streaming fashion.
+
+```java { .api }
+public class JsonWriter implements Closeable, Flushable {
+    public JsonWriter(Writer out);
+    
+    // Configuration

+    public void setHtmlSafe(boolean htmlSafe);
+    public boolean isHtmlSafe();
+    public void setSerializeNulls(boolean serializeNulls);
+    public boolean getSerializeNulls();
+    
+    // Object writing
+    public JsonWriter beginObject() throws IOException;
+    public JsonWriter endObject() throws IOException;
+    public JsonWriter name(String name) throws IOException;
+    
+    // Array writing
+    public JsonWriter beginArray() throws IOException;
+    public JsonWriter endArray() throws IOException;
+    
+    // Value writing
+    public JsonWriter value(String value) throws IOException;
+    public JsonWriter nullValue() throws IOException;
+    public JsonWriter value(boolean value) throws IOException;
+    public JsonWriter value(Boolean value) throws IOException;
+    public JsonWriter value(double value) throws IOException;
+    public JsonWriter value(long value) throws IOException;
+    public JsonWriter value(Number value) throws IOException;
+

+    public JsonWriter jsonValue(String value) throws IOException;
+    
+    // Resource management
+    public void flush() throws IOException;
+    public void close() throws IOException;
+}
+```
+
+**Writing JSON objects:**
+```java
+StringWriter stringWriter = new StringWriter();
+JsonWriter writer = new JsonWriter(stringWriter);
+
+writer.beginObject();
+writer.name("name").value("Alice");
+writer.name("age").value(30);
+writer.name("active").value(true);
+writer.name("salary").nullValue();
+writer.endObject();
+
+writer.close();
+String json = stringWriter.toString();
+// Result: {"name":"Alice","age":30,"active":true,"salary":null}
+```
+
+**Writing JSON arrays:**
+```java
+StringWriter stringWriter = new StringWriter();
+JsonWriter writer = new JsonWriter(stringWriter);
+
+writer.beginArray();
+writer.value(1);
+writer.value(2);
+writer.value(3);
+writer.endArray();
+
+writer.close();
+String json = stringWriter.toString();
+// Result: [1,2,3]
+```
+
+**Writing complex nested structures:**
+```java
+StringWriter stringWriter = new StringWriter();
+JsonWriter writer = new JsonWriter(stringWriter);
+
+writer.beginObject();
+writer.name("users");
+writer.beginArray();
+
+writer.beginObject();
+writer.name("name").value("Alice");
+writer.name("age").value(30);
+writer.name("hobbies");
+writer.beginArray();
+writer.value("reading");
+writer.value("swimming");
+writer.endArray();
+writer.endObject();
+
+writer.beginObject();
+writer.name("name").value("Bob");
+writer.name("age").value(25);
+writer.name("hobbies");
+writer.beginArray();
+writer.value("gaming");
+writer.endArray();
+writer.endObject();
+
+writer.endArray();
+writer.endObject();
+
+writer.close();
+```
+
+## Gson Integration
+
+Create JsonReader and JsonWriter through Gson for consistent configuration:
+
+```java { .api }
+public JsonWriter newJsonWriter(Writer writer) throws IOException;
+public JsonReader newJsonReader(Reader reader);
+```
+
+**Usage:**
+```java
+Gson gson = new GsonBuilder()
+    .setPrettyPrinting()
+    .setLenient()
+    .create();
+
+// Create configured writer
+StringWriter stringWriter = new StringWriter();
+JsonWriter writer = gson.newJsonWriter(stringWriter);
+
+// Create configured reader
+JsonReader reader = gson.newJsonReader(new StringReader(json));
+```
+
+## Error Handling
+
+```java { .api }
+class MalformedJsonException extends IOException {
+    // Thrown when JSON structure is invalid
+}
+```
+
+**Error handling example:**
+```java
+try {
+    JsonReader reader = new JsonReader(new StringReader(malformedJson));
+    reader.beginObject();
+    // ... reading logic
+} catch (MalformedJsonException e) {
+    System.err.println("Malformed JSON: " + e.getMessage());
+} catch (IOException e) {
+    System.err.println("I/O error: " + e.getMessage());
+}
+```
+
+## Advanced Usage
+
+### Lenient Mode
+
+Allow relaxed JSON syntax:
+```java
+JsonReader reader = new JsonReader(new StringReader(json));
+reader.setLenient(true);
+
+// Now can read: {name: 'Alice', age: 30} (unquoted names, single quotes)
+```
+
+### Pretty Printing
+
+Configure indentation for readable output:
+```java
+JsonWriter writer = new JsonWriter(new FileWriter("output.json"));
+writer.setIndent("  "); // 2-space indentation
+
+writer.beginObject();
+writer.name("name").value("Alice");
+writer.name("details");
+writer.beginObject();
+writer.name("age").value(30);
+writer.endObject();
+writer.endObject();
+```
+
+### Large File Processing
+
+Process large JSON files efficiently:
+```java
+// Reading large file
+try (FileReader fileReader = new FileReader("large-data.json");
+     JsonReader reader = new JsonReader(fileReader)) {
+    
+    reader.beginArray();
+    while (reader.hasNext()) {
+        // Process each object without loading entire file
+        processObject(reader);
+    }
+    reader.endArray();
+}
+
+private void processObject(JsonReader reader) throws IOException {
+    reader.beginObject();
+    while (reader.hasNext()) {
+        String name = reader.nextName();
+        // Handle each field as needed
+        if ("data".equals(name)) {
+            // Process data field
+        } else {
+            reader.skipValue();
+        }
+    }
+    reader.endObject();
+}
+```
+
+### Custom Adapter Integration
+
+Use streaming API within custom TypeAdapters:
+```java
+public class PersonAdapter extends TypeAdapter<Person> {
+    @Override
+    public void write(JsonWriter out, Person person) throws IOException {
+        out.beginObject();
+        out.name("name").value(person.getName());
+        out.name("age").value(person.getAge());
+        out.endObject();
+    }
+    
+    @Override
+    public Person read(JsonReader in) throws IOException {
+        Person person = new Person();
+        in.beginObject();
+        while (in.hasNext()) {
+            String name = in.nextName();
+            switch (name) {
+                case "name":
+                    person.setName(in.nextString());
+                    break;
+                case "age":
+                    person.setAge(in.nextInt());
+                    break;
+                default:
+                    in.skipValue();
+                    break;
+            }
+        }
+        in.endObject();
+        return person;
+    }
+}

+# Type Adapters
+
+Type adapters provide fine-grained control over JSON serialization and deserialization for specific types. They are the most flexible way to customize Gson's behavior.
+
+## TypeAdapter Abstract Class
+
+The base class for all type adapters.
+
+```java { .api }
+public abstract class TypeAdapter<T> {
+    public abstract void write(JsonWriter out, T value) throws IOException;
+    public abstract T read(JsonReader in) throws IOException;
+    
+    // Convenience methods
+    public final String toJson(T value);
+    public final void toJson(Writer out, T value) throws IOException;
+    public final T fromJson(String json) throws IOException;
+    public final T fromJson(Reader in) throws IOException;
+    
+    // Null handling
+    public final TypeAdapter<T> nullSafe();
+}
+```
+
+## Creating Custom Type Adapters
+
+**Basic type adapter example:**
+```java
+public class PersonAdapter extends TypeAdapter<Person> {
+    @Override
+    public void write(JsonWriter out, Person person) throws IOException {
+        if (person == null) {
+            out.nullValue();
+            return;
+        }
+        
+        out.beginObject();
+        out.name("name").value(person.getName());
+        out.name("age").value(person.getAge());
+        out.name("email").value(person.getEmail());
+        out.endObject();
+    }
+    
+    @Override
+    public Person read(JsonReader in) throws IOException {
+        if (in.peek() == JsonToken.NULL) {
+            in.nextNull();
+            return null;
+        }
+        
+        Person person = new Person();
+        in.beginObject();
+        while (in.hasNext()) {
+            String name = in.nextName();
+            switch (name) {
+                case "name":
+                    person.setName(in.nextString());
+                    break;
+                case "age":
+                    person.setAge(in.nextInt());
+                    break;
+                case "email":
+                    person.setEmail(in.nextString());
+                    break;
+                default:
+                    in.skipValue(); // Skip unknown properties
+                    break;
+            }
+        }
+        in.endObject();
+        return person;
+    }
+}
+```
+
+**Registering the adapter:**
+```java
+Gson gson = new GsonBuilder()
+    .registerTypeAdapter(Person.class, new PersonAdapter())
+    .create();
+
+Person person = new Person("Alice", 30, "alice@example.com");
+String json = gson.toJson(person);
+Person restored = gson.fromJson(json, Person.class);
+```
+
+## TypeAdapterFactory Interface
+
+Factory pattern for creating type adapters dynamically.
+
+```java { .api }
+public interface TypeAdapterFactory {
+    public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> type);
+}
+```
+
+**Example factory for enum handling:**
+```java
+public class LowercaseEnumTypeAdapterFactory implements TypeAdapterFactory {
+    @Override
+    @SuppressWarnings("unchecked")
+    public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> type) {
+        Class<T> rawType = (Class<T>) type.getRawType();
+        if (!rawType.isEnum()) {
+            return null; // This factory only handles enums
+        }
+        
+        return new TypeAdapter<T>() {
+            @Override
+            public void write(JsonWriter out, T value) throws IOException {
+                if (value == null) {
+                    out.nullValue();
+                } else {
+                    out.value(value.toString().toLowerCase());
+                }
+            }
+            
+            @Override
+            @SuppressWarnings("unchecked")
+            public T read(JsonReader in) throws IOException {
+                if (in.peek() == JsonToken.NULL) {
+                    in.nextNull();
+                    return null;
+                }
+                
+                String value = in.nextString().toUpperCase();
+                return (T) Enum.valueOf((Class<Enum>) rawType, value);
+            }
+        };
+    }
+}
+```
+
+**Registering the factory:**
+```java
+Gson gson = new GsonBuilder()
+    .registerTypeAdapterFactory(new LowercaseEnumTypeAdapterFactory())
+    .create();
+```
+
+## Built-in Type Adapters
+
+Gson provides many built-in type adapters accessible through the TypeAdapters utility class.
+
+```java { .api }
+public final class TypeAdapters {
+    public static final TypeAdapter<Class> CLASS;
+    public static final TypeAdapter<Boolean> BOOLEAN;
+    public static final TypeAdapter<Boolean> BOOLEAN_AS_STRING;
+    public static final TypeAdapter<Number> BYTE;
+    public static final TypeAdapter<Number> SHORT;
+    public static final TypeAdapter<Number> INTEGER;
+    public static final TypeAdapter<AtomicInteger> ATOMIC_INTEGER;
+    public static final TypeAdapter<AtomicBoolean> ATOMIC_BOOLEAN;
+    public static final TypeAdapter<Number> LONG;
+    public static final TypeAdapter<Number> FLOAT;
+    public static final TypeAdapter<Number> DOUBLE;
+    public static final TypeAdapter<Character> CHARACTER;
+    public static final TypeAdapter<String> STRING;
+    public static final TypeAdapter<StringBuilder> STRING_BUILDER;
+    public static final TypeAdapter<StringBuffer> STRING_BUFFER;
+    public static final TypeAdapter<URL> URL;
+    public static final TypeAdapter<URI> URI;
+    public static final TypeAdapter<UUID> UUID;
+    public static final TypeAdapter<Currency> CURRENCY;
+    public static final TypeAdapter<Calendar> CALENDAR;
+    public static final TypeAdapter<Locale> LOCALE;
+    public static final TypeAdapter<JsonElement> JSON_ELEMENT;
+    
+    // Factory methods
+    public static <TT> TypeAdapterFactory newFactory(Class<TT> type, TypeAdapter<TT> typeAdapter);
+    public static <TT> TypeAdapterFactory newFactory(TypeToken<TT> type, TypeAdapter<TT> typeAdapter);
+    public static TypeAdapterFactory newFactoryForMultipleTypes(Class<?> base, Class<?> sub, TypeAdapter<?> typeAdapter);
+}
+```
+
+## Advanced Type Adapter Patterns
+
+### Generic Type Handling
+
+```java
+public class ListTypeAdapterFactory implements TypeAdapterFactory {
+    @Override
+    @SuppressWarnings("unchecked")
+    public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> type) {
+        Type rawType = type.getRawType();
+        if (rawType != List.class) {
+            return null;
+        }
+        
+        Type elementType = ((ParameterizedType) type.getType()).getActualTypeArguments()[0];
+        TypeAdapter<?> elementAdapter = gson.getAdapter(TypeToken.get(elementType));
+        
+        return (TypeAdapter<T>) new TypeAdapter<List<?>>() {
+            @Override
+            public void write(JsonWriter out, List<?> list) throws IOException {
+                if (list == null) {
+                    out.nullValue();
+                    return;
+                }
+                
+                out.beginArray();
+                for (Object element : list) {
+                    elementAdapter.write(out, element);
+                }
+                out.endArray();
+            }
+            
+            @Override
+            public List<?> read(JsonReader in) throws IOException {
+                if (in.peek() == JsonToken.NULL) {
+                    in.nextNull();
+                    return null;
+                }
+                
+                List<Object> list = new ArrayList<>();
+                in.beginArray();
+                while (in.hasNext()) {
+                    list.add(elementAdapter.read(in));
+                }
+                in.endArray();
+                return list;
+            }
+        };
+    }
+}
+```
+
+### Delegating Adapters
+
+Sometimes you need to modify the behavior of an existing adapter:
+
+```java
+public class TimestampAdapter extends TypeAdapter<Date> {
+    private final TypeAdapter<Date> delegate;
+    
+    public TimestampAdapter(TypeAdapter<Date> delegate) {
+        this.delegate = delegate;
+    }
+    
+    @Override
+    public void write(JsonWriter out, Date date) throws IOException {
+        if (date == null) {
+            out.nullValue();
+        } else {
+            out.value(date.getTime()); // Write as timestamp
+        }
+    }
+    
+    @Override
+    public Date read(JsonReader in) throws IOException {
+        if (in.peek() == JsonToken.NULL) {
+            in.nextNull();
+            return null;
+        }
+        
+        long timestamp = in.nextLong();
+        return new Date(timestamp);
+    }
+}
+```
+
+### Hierarchical Type Adapters
+
+Handle inheritance hierarchies:
+
+```java
+Gson gson = new GsonBuilder()
+    .registerTypeHierarchyAdapter(Animal.class, new AnimalAdapter())
+    .create();
+
+// This adapter will be used for Animal and all its subclasses
+public class AnimalAdapter implements JsonSerializer<Animal>, JsonDeserializer<Animal> {
+    @Override
+    public JsonElement serialize(Animal src, Type typeOfSrc, JsonSerializationContext context) {
+        JsonObject result = new JsonObject();
+        result.add("type", new JsonPrimitive(src.getClass().getSimpleName()));
+        result.add("properties", context.serialize(src, src.getClass()));
+        return result;
+    }
+    
+    @Override
+    public Animal deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
+        JsonObject jsonObject = json.getAsJsonObject();
+        String type = jsonObject.get("type").getAsString();
+        JsonElement element = jsonObject.get("properties");
+        
+        try {
+            Class<?> clazz = Class.forName("com.example." + type);
+            return context.deserialize(element, clazz);
+        } catch (ClassNotFoundException e) {
+            throw new JsonParseException("Unknown element type: " + type, e);
+        }
+    }
+}
+```
+
+## Null Handling
+
+Type adapters can handle nulls explicitly or use the `nullSafe()` wrapper:
+
+```java
+public class NullSafeStringAdapter extends TypeAdapter<String> {
+    @Override
+    public void write(JsonWriter out, String value) throws IOException {
+        out.value(value == null ? "NULL" : value);
+    }
+    
+    @Override
+    public String read(JsonReader in) throws IOException {
+        String value = in.nextString();
+        return "NULL".equals(value) ? null : value;
+    }
+}
+
+// Or use nullSafe wrapper
+TypeAdapter<String> adapter = new StringAdapter().nullSafe();
+```
+
+## Accessing Delegate Adapters
+
+Get the next adapter in the chain to avoid infinite recursion:
+
+```java
+Gson gson = new GsonBuilder()
+    .registerTypeAdapterFactory(new LoggingAdapterFactory())
+    .create();
+
+public class LoggingAdapterFactory implements TypeAdapterFactory {
+    @Override
+    public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> type) {
+        TypeAdapter<T> delegate = gson.getDelegateAdapter(this, type);
+        
+        return new TypeAdapter<T>() {
+            @Override
+            public void write(JsonWriter out, T value) throws IOException {
+                System.out.println("Serializing: " + value);
+                delegate.write(out, value);
+            }
+            
+            @Override
+            public T read(JsonReader in) throws IOException {
+                T result = delegate.read(in);
+                System.out.println("Deserialized: " + result);
+                return result;
+            }
+        };
+    }
+}
+```
+
+## Legacy Serializer/Deserializer Interfaces
+
+For simpler cases, you can use the legacy interfaces:
+
+```java { .api }
+public interface JsonSerializer<T> {
+    public JsonElement serialize(T src, Type typeOfSrc, JsonSerializationContext context);
+}
+
+public interface JsonDeserializer<T> {
+    public T deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException;
+}
+```
+
+**Context interfaces:**
+```java { .api }
+public interface JsonSerializationContext {
+    public JsonElement serialize(Object src);
+    public JsonElement serialize(Object src, Type typeOfSrc);
+}
+
+public interface JsonDeserializationContext {
+    public <T> T deserialize(JsonElement json, Type typeOfT) throws JsonParseException;
+}
+```
+
+**Usage:**
+```java
+public class PersonSerializer implements JsonSerializer<Person> {
+    @Override
+    public JsonElement serialize(Person src, Type typeOfSrc, JsonSerializationContext context) {
+        JsonObject obj = new JsonObject();
+        obj.addProperty("fullName", src.getFirstName() + " " + src.getLastName());
+        obj.addProperty("age", src.getAge());
+        return obj;
+    }
+}
+
+Gson gson = new GsonBuilder()
+    .registerTypeAdapter(Person.class, new PersonSerializer())
+    .create();
+```

+# JaCoCo Agent
+
+JaCoCo Agent provides programmatic access to the JaCoCo runtime agent JAR file for Java code coverage analysis. This module serves as a wrapper and resource provider for the jacocoagent.jar file, offering APIs to extract, access, and deploy the coverage agent in various Java environments.
+
+## Package Information
+
+- **Package Name**: org.jacoco.agent
+- **Package Type**: maven
+- **Language**: Java
+- **Installation**: 
+  ```xml
+  <dependency>
+    <groupId>org.jacoco</groupId>
+    <artifactId>org.jacoco.agent</artifactId>
+    <version>0.8.13</version>
+  </dependency>
+  ```
+
+## Core Imports
+
+```java
+import org.jacoco.agent.AgentJar;
+import java.io.File;
+import java.io.InputStream;
+import java.io.IOException;
+import java.net.URL;
+```
+
+## Basic Usage
+
+```java
+import org.jacoco.agent.AgentJar;
+import java.io.File;
+import java.io.IOException;
+
+// Get the agent JAR as a URL
+URL agentUrl = AgentJar.getResource();
+
+// Get the agent JAR as an InputStream
+InputStream agentStream = AgentJar.getResourceAsStream();
+
+// Extract agent to a temporary location
+File tempAgent = AgentJar.extractToTempLocation();
+
+// Extract agent to a specific location
+File specificLocation = new File("/path/to/jacocoagent.jar");
+AgentJar.extractTo(specificLocation);
+```
+
+## Capabilities
+
+### Agent Resource Access
+
+Access the embedded JaCoCo agent JAR file as a resource.
+
+```java { .api }
+/**
+ * Returns a URL pointing to the JAR file.
+ * @return URL of the JAR file
+ */
+public static URL getResource();
+
+/**
+ * Returns the content of the JAR file as a stream.
+ * @return content of the JAR file
+ */
+public static InputStream getResourceAsStream();
+```
+
+**Usage Examples:**
+
+```java
+// Access via URL
+URL agentUrl = AgentJar.getResource();
+InputStream stream = agentUrl.openStream();
+
+// Direct stream access with proper resource management
+try (InputStream agentStream = AgentJar.getResourceAsStream()) {
+    // Use the stream for processing
+    // Stream is automatically closed when try block exits
+}
+```
+
+### Agent Extraction
+
+Extract the embedded agent JAR to file system locations.
+
+```java { .api }
+/**
+ * Extract the JaCoCo agent JAR and put it into a temporary location. This
+ * file should be deleted on exit, but may not if the VM is terminated
+ * @return Location of the Agent Jar file in the local file system. The file
+ *         should exist and be readable.
+ * @throws IOException Unable to unpack agent jar
+ */
+public static File extractToTempLocation() throws IOException;
+
+/**
+ * Extract the JaCoCo agent JAR and put it into the specified location.
+ * @param destination Location to write JaCoCo Agent Jar to. Must be writeable
+ * @throws IOException Unable to unpack agent jar
+ */
+public static void extractTo(File destination) throws IOException;
+```
+
+**Usage Examples:**
+
+```java
+// Extract to temporary location (automatically deleted on JVM exit)
+File tempAgentFile = AgentJar.extractToTempLocation();
+System.out.println("Agent extracted to: " + tempAgentFile.getAbsolutePath());
+
+// Extract to specific location
+File agentFile = new File("./jacocoagent.jar");
+try {
+    AgentJar.extractTo(agentFile);
+    System.out.println("Agent extracted to: " + agentFile.getAbsolutePath());
+} catch (IOException e) {
+    System.err.println("Failed to extract agent: " + e.getMessage());
+}
+```
+
+## Types
+
+```java { .api }
+public final class AgentJar {
+    // Private constructor - cannot be instantiated
+    private AgentJar();
+    
+    // All methods are static
+}
+```
+
+## Error Handling
+
+The JaCoCo Agent API uses two main types of exceptions:
+
+- **AssertionError**: Thrown when the embedded `/jacocoagent.jar` resource is not found. This typically indicates a build or packaging issue. The error includes a reference to `/org.jacoco.agent/README.TXT` for troubleshooting details.
+- **IOException**: Thrown by extraction methods for I/O related failures, such as:
+  - Destination file is not writable
+  - Destination path does not exist
+  - Insufficient disk space
+  - File system permissions issues
+
+**Error Handling Example:**
+
+```java
+try {
+    // Resource access - may throw AssertionError
+    URL agentUrl = AgentJar.getResource();
+    
+    // File extraction - may throw IOException  
+    File agentFile = new File("./jacocoagent.jar");
+    AgentJar.extractTo(agentFile);
+    
+} catch (AssertionError e) {
+    System.err.println("Agent resource not found. Check build configuration.");
+} catch (IOException e) {
+    System.err.println("Failed to extract agent: " + e.getMessage());
+}
+```
+
+## Key Characteristics
+
+- **Utility Class**: AgentJar is a final class with only static methods and private constructor (cannot be instantiated)
+- **Resource Provider**: Acts as a wrapper around the embedded `/jacocoagent.jar` resource within the JAR file
+- **Thread Safety**: All methods are static and thread-safe
+- **Self-Contained**: Includes the complete agent JAR as an embedded resource at runtime
+- **Build Integration**: The agent JAR is created and embedded during the Maven build process
+- **No External Dependencies**: Pure Java implementation using only standard library classes
+- **Safe Resource Handling**: Internal implementation uses safe stream closing to prevent resource leaks
+
+## Integration Patterns
+
+Common usage patterns for integrating JaCoCo Agent in applications:
+
+**Testing Framework Integration:**
+```java
+// Extract agent for use with JVM arguments
+File agent = AgentJar.extractToTempLocation();
+String javaagentArg = "-javaagent:" + agent.getAbsolutePath();
+// Use javaagentArg when launching test JVMs
+```
+
+**Build Tool Integration:**
+```java
+// Extract to build directory for distribution
+File buildDir = new File("target/jacoco");
+buildDir.mkdirs();
+File agentJar = new File(buildDir, "jacocoagent.jar");
+AgentJar.extractTo(agentJar);
+```
+
+**Runtime Deployment:**
+```java
+// Use the built-in extraction method for deployment
+File deploymentFile = new File("/path/to/deployment/jacocoagent.jar");
+AgentJar.extractTo(deploymentFile);
+// The extractTo method handles stream management and proper copying
+```

+Comprehensive assertion methods for verifying test conditions and assumptions for conditional test execution. JUnit Jupiter provides a rich set of assertion methods with clear failure messages and support for custom error messages.
+
+## Imports
+
+```java
+import static org.junit.jupiter.api.Assertions.*;
+import static org.junit.jupiter.api.Assumptions.*;
+```
+
+## Capabilities
+
+### Basic Assertions
+
+Core assertion methods for common verification scenarios.
+
+```java { .api }
+/**
+ * Assert that two objects are equal
+ */
+static void assertEquals(Object expected, Object actual);
+static void assertEquals(Object expected, Object actual, String message);
+static void assertEquals(Object expected, Object actual, Supplier<String> messageSupplier);

+static void assertNotEquals(Object unexpected, Object actual, String message);
+static void assertNotEquals(Object unexpected, Object actual, Supplier<String> messageSupplier);
+
+/**
+ * Assert that a condition is true
+ */
+static void assertTrue(boolean condition);
+static void assertTrue(boolean condition, String message);

+
+/**
+ * Assert that an object is not null
+ */
+static void assertNotNull(Object actual);
+static void assertNotNull(Object actual, String message);
+static void assertNotNull(Object actual, Supplier<String> messageSupplier);
+```
+
+**Usage Examples:**

+void testBasicAssertions() {
+    assertEquals(4, 2 + 2, "Simple addition should work");
+    assertNotEquals(3, 2 + 2);
+    assertTrue(5 > 3, "5 should be greater than 3");
+    assertFalse(5 < 3);
+    
+    String nullString = null;
+    String nonNullString = "hello";
+    assertNull(nullString);
+    assertNotNull(nonNullString, "String should not be null");
+}
+```
+
+### Reference Assertions
+
+Assert object identity and reference equality.
+
+```java { .api }
+/**
+ * Assert that two objects refer to the same object
+ */
+static void assertSame(Object expected, Object actual);
+static void assertSame(Object expected, Object actual, String message);
+static void assertSame(Object expected, Object actual, Supplier<String> messageSupplier);
+
+/**
+ * Assert that two objects do not refer to the same object
+ */
+static void assertNotSame(Object unexpected, Object actual);
+static void assertNotSame(Object unexpected, Object actual, String message);
+static void assertNotSame(Object unexpected, Object actual, Supplier<String> messageSupplier);
+```
+
+**Usage Example:**
+
+```java
+@Test
+void testReferenceAssertions() {
+    String str1 = new String("hello");
+    String str2 = new String("hello");
+    String str3 = str1;
+    
+    assertEquals(str1, str2); // Content equality
+    assertNotSame(str1, str2, "Different objects should not be same");
+    assertSame(str1, str3, "Same reference should be same");
+}
+```
+
+### Array and Collection Assertions
+
+Specialized assertions for arrays and collections.
+
+```java { .api }
+/**

+        () -> assertTrue(person.getAge() > 0),
+        () -> assertNotNull(person.getFullName())
+    );
+    
+    // Using collections

+        () -> assertEquals(4, 2 + 2),
+        () -> assertTrue(5 > 3),
+        () -> assertNotNull("test")
+    );
+    assertAll("Math assertions", assertions);

+    boolean condition = false;
+    
+    if (!condition) {
+        fail("Condition was not met");
+    }
+

+    }
+    
+    // In switch statement
+    switch (value) {
+        case 1: /* handle */ break;
+        case 2: /* handle */ break;
+        default: fail("Unexpected value: " + value);
+    }
+}
+```
+

+
+/**
+ * Execute test code only if assumption is true
+ */
+static void assumingThat(boolean assumption, Executable executable);
+static void assumingThat(BooleanSupplier assumptionSupplier, Executable executable);
+```
+
+**Usage Examples:**
+
+```java
+@Test
+void testOnlyOnLinux() {
+    assumeTrue(System.getProperty("os.name").toLowerCase().contains("linux"));
+    
+    // This test will only run on Linux
+    // Will be skipped (not failed) on other operating systems
+    assertEquals("/", File.separator);
+}
+
+@Test
+void testWithPartialAssumption() {
+    // This part always runs
+    assertEquals(4, 2 + 2);
+    
+    // This part only runs if assumption is true
+    assumingThat(System.getProperty("env").equals("dev"), () -> {
+        // Development-only test code
+        assertEquals("localhost", getServerHost());
+    });
+    
+    // This part always runs
+    assertTrue(true);
+}
+
+@Test
+void testWithEnvironmentCheck() {
+    String env = System.getProperty("test.env");
+    assumeFalse("prod".equals(env), "Not running destructive test in production");
+    
+    // Destructive test that should not run in production
+    database.deleteAllData();
+}
+```
+
+### Assertion Failure Builder

+    
+    /**
+     * Set failure message
+     */
+    AssertionFailureBuilder message(String message);
+    
+    /**
+     * Set expected value
+     */
+    AssertionFailureBuilder expected(Object expected);
+    
+    /**
+     * Set actual value  
+     */
+    AssertionFailureBuilder actual(Object actual);
+    
+    /**
+     * Set cause exception
+     */
+    AssertionFailureBuilder cause(Throwable cause);
+    
+    /**
+     * Build the assertion failure
+     */
+    AssertionFailedError build();
+}
+```
+
+**Usage Example:**
+
+```java
+@Test
+void testCustomAssertion() {
+    String expected = "hello";

+# Core Testing API
+
+Essential testing annotations and lifecycle methods that form the foundation of JUnit Jupiter tests. These provide the basic structure for organizing and executing tests with modern Java features.
+
+## Imports
+
+```java
+import org.junit.jupiter.api.*;
+import static org.junit.jupiter.api.Assertions.*;
+```
+
+## Capabilities
+
+### Test Annotation
+
+Marks a method as a test method that should be executed by the test engine.
+
+```java { .api }
+/**
+ * Marks a method as a test method
+ */
+@Target({ElementType.ANNOTATION_TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface Test {
+}
+```
+
+**Usage Example:**
+
+```java
+class MyTest {
+    @Test
+    void shouldCalculateCorrectly() {
+        // Test implementation
+        assertEquals(4, 2 + 2);
+    }
+}
+```
+
+### Lifecycle Annotations
+
+Control test execution lifecycle with setup and teardown methods.
+
+```java { .api }
+/**
+ * Executed once before all test methods in the class
+ * Method must be static
+ */
+@Target({ElementType.ANNOTATION_TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface BeforeAll {
+}
+
+/**
+ * Executed before each individual test method
+ */
+@Target({ElementType.ANNOTATION_TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface BeforeEach {
+}
+
+/**
+ * Executed after each individual test method
+ */
+@Target({ElementType.ANNOTATION_TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface AfterEach {
+}
+
+/**
+ * Executed once after all test methods in the class
+ * Method must be static
+ */
+@Target({ElementType.ANNOTATION_TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface AfterAll {
+}
+```
+
+**Usage Example:**
+
+```java
+class DatabaseTest {
+    static Database database;
+    Connection connection;
+
+    @BeforeAll
+    static void initDatabase() {
+        database = new Database();
+        database.start();
+    }
+
+    @AfterAll
+    static void cleanupDatabase() {
+        database.stop();
+    }
+
+    @BeforeEach
+    void openConnection() {
+        connection = database.openConnection();
+    }
+
+    @AfterEach
+    void closeConnection() {
+        if (connection != null) {
+            connection.close();
+        }
+    }
+
+    @Test
+    void testQuery() {
+        // Test with connection
+    }
+}
+```
+
+### Display Names
+
+Customize test names for better readability in test reports.
+
+```java { .api }
+/**
+ * Custom display name for tests and test classes
+ */
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface DisplayName {
+    String value();
+}
+
+/**
+ * Generate display names using a specific strategy
+ */
+@Target({ElementType.TYPE})
+@Retention(RetentionPolicy.RUNTIME)
+@interface DisplayNameGeneration {
+    Class<? extends DisplayNameGenerator> value();
+}
+```
+
+**Usage Example:**
+
+```java
+@DisplayName("Calculator Tests")
+class CalculatorTest {
+
+    @Test
+    @DisplayName("Addition should work for positive numbers")
+    void testAddition() {
+        assertEquals(5, 2 + 3);
+    }
+
+    @Test
+    @DisplayName("Division by zero should throw exception")
+    void testDivisionByZero() {
+        assertThrows(ArithmeticException.class, () -> 10 / 0);
+    }
+}
+```
+
+### Display Name Generators
+
+Built-in strategies for generating display names automatically.
+
+```java { .api }
+interface DisplayNameGenerator {
+    String generateDisplayNameForClass(Class<?> testClass);
+    String generateDisplayNameForNestedClass(Class<?> nestedClass);
+    String generateDisplayNameForMethod(Class<?> testClass, Method testMethod);
+
+    class Standard implements DisplayNameGenerator { }
+    class Simple implements DisplayNameGenerator { }
+    class ReplaceUnderscores implements DisplayNameGenerator { }
+    class IndicativeSentences implements DisplayNameGenerator { }
+}
+```
+
+### Nested Tests
+
+Organize related tests in hierarchical structure using nested classes.
+
+```java { .api }
+/**
+ * Marks a nested class as a test class
+ */
+@Target(ElementType.TYPE)
+@Retention(RetentionPolicy.RUNTIME)
+@interface Nested {
+}
+```
+
+**Usage Example:**
+
+```java
+class AccountTest {
+
+    @Test
+    void testCreateAccount() {
+        // Test account creation
+    }
+
+    @Nested
+    @DisplayName("When account has balance")
+    class WhenAccountHasBalance {
+
+        Account account;
+
+        @BeforeEach
+        void createAccountWithBalance() {
+            account = new Account(100);
+        }
+
+        @Test
+        @DisplayName("withdraw should decrease balance")
+        void withdrawShouldDecreaseBalance() {
+            account.withdraw(20);
+            assertEquals(80, account.getBalance());
+        }
+
+        @Nested
+        @DisplayName("And withdrawal amount exceeds balance")
+        class AndWithdrawalExceedsBalance {
+
+            @Test
+            @DisplayName("should throw InsufficientFundsException")
+            void shouldThrowException() {
+                assertThrows(InsufficientFundsException.class, 
+                    () -> account.withdraw(150));
+            }
+        }
+    }
+}
+```
+
+### Test Disabling
+
+Disable tests temporarily or conditionally.
+
+```java { .api }
+/**
+ * Disable test execution with optional reason
+ */
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface Disabled {
+    String value() default "";
+}
+```
+
+**Usage Example:**
+
+```java
+class FeatureTest {
+
+    @Test
+    @Disabled("Feature not yet implemented")
+    void testNewFeature() {
+        // This test won't run
+    }
+
+    @Test
+    @Disabled
+    void temporarilyDisabled() {
+        // This test won't run either
+    }
+}
+```
+
+### Test Tagging
+
+Tag tests for filtering and selective execution.
+
+```java { .api }
+/**
+ * Tag a test for filtering
+ */
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@Repeatable(Tags.class)
+@interface Tag {
+    String value();
+}
+
+/**
+ * Container for multiple tags
+ */
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface Tags {
+    Tag[] value();
+}
+```
+
+**Usage Example:**
+
+```java
+class IntegrationTest {
+
+    @Test
+    @Tag("fast")
+    void testQuickOperation() {
+        // Fast test
+    }
+
+    @Test
+    @Tag("slow")
+    @Tag("integration")
+    void testDatabaseIntegration() {
+        // Slow integration test
+    }
+
+    @Test
+    @Tags({@Tag("smoke"), @Tag("critical")})
+    void testCriticalPath() {
+        // Critical smoke test
+    }
+}
+```
+
+### Repeated Tests
+
+Execute the same test multiple times with repetition information.
+
+```java { .api }
+/**
+ * Repeat test execution multiple times
+ */
+@Target(ElementType.METHOD)
+@Retention(RetentionPolicy.RUNTIME)
+@interface RepeatedTest {
+    int value();
+    String name() default "";
+}
+```
+
+**Usage Example:**
+
+```java
+class RandomTest {
+
+    @RepeatedTest(10)
+    void testRandomBehavior() {
+        int random = (int) (Math.random() * 100);
+        assertTrue(random >= 0 && random < 100);
+    }
+
+    @RepeatedTest(value = 5, name = "Run {currentRepetition} of {totalRepetitions}")
+    void testWithCustomName(RepetitionInfo repetitionInfo) {
+        System.out.println("Repetition: " + repetitionInfo.getCurrentRepetition());
+    }
+}
+```
+
+### Test Information
+
+Access test metadata at runtime.
+
+```java { .api }
+interface TestInfo {
+    String getDisplayName();
+    Set<String> getTags();
+    Optional<Class<?>> getTestClass();
+    Optional<Method> getTestMethod();
+}
+
+interface RepetitionInfo {
+    int getCurrentRepetition();
+    int getTotalRepetitions();
+}
+```
+
+**Usage Example:**
+
+```java
+class InfoTest {
+
+    @Test
+    void testWithInfo(TestInfo testInfo) {
+        System.out.println("Test name: " + testInfo.getDisplayName());
+        System.out.println("Tags: " + testInfo.getTags());
+    }
+
+    @RepeatedTest(3)
+    void repeatedTestWithInfo(RepetitionInfo repetitionInfo) {
+        System.out.println("Repetition " + repetitionInfo.getCurrentRepetition() 
+            + " of " + repetitionInfo.getTotalRepetitions());
+    }
+}
+```
+
+### Test Ordering
+
+Control the order of test execution.
+
+```java { .api }
+/**
+ * Configure test method execution order
+ */
+@Target(ElementType.TYPE)
+@Retention(RetentionPolicy.RUNTIME)
+@interface TestMethodOrder {
+    Class<? extends MethodOrderer> value();
+}
+
+/**
+ * Configure test class execution order
+ */
+@Target(ElementType.TYPE)
+@Retention(RetentionPolicy.RUNTIME)
+@interface TestClassOrder {
+    Class<? extends ClassOrderer> value();
+}
+
+/**
+ * Specify execution order
+ */
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface Order {
+    int value();
+}
+```
+
+**Usage Example:**
+
+```java
+@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
+class OrderedTest {
+
+    @Test
+    @Order(3)
+    void testThird() {
+        // Runs third
+    }
+
+    @Test
+    @Order(1)
+    void testFirst() {
+        // Runs first
+    }
+
+    @Test
+    @Order(2)
+    void testSecond() {
+        // Runs second
+    }
+}
+```
+
+### Test Instance Lifecycle
+
+Control how test instances are created and managed.
+
+```java { .api }
+/**
+ * Configure test instance lifecycle
+ */
+@Target(ElementType.TYPE)
+@Retention(RetentionPolicy.RUNTIME)

+    Lifecycle value();
+
+    enum Lifecycle {
+        PER_METHOD,  // Default: new instance per test method
+        PER_CLASS    // One instance per test class
+    }
+}
+```
+
+**Usage Example:**
+
+```java
+@TestInstance(TestInstance.Lifecycle.PER_CLASS)
+class SharedStateTest {
+    int counter = 0;
+
+    @Test
+    void firstTest() {
+        counter++;
+        assertEquals(1, counter);
+    }
+
+    @Test
+    void secondTest() {
+        counter++;
+        assertEquals(2, counter); // Works because same instance
+    }
+}
+```
+
+### Test Timeouts
+
+Configure execution timeouts for individual tests or entire test classes.
+
+```java { .api }
+/**
+ * Configure test execution timeout
+ */
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface Timeout {
+    /**
+     * Timeout value
+     */
+    long value();
+    
+    /**
+     * Time unit for timeout value
+     */
+    TimeUnit unit() default TimeUnit.SECONDS;
+    
+    /**

+         */
+        SAME_THREAD,
+        
+        /**
+         * Execute in separate thread and interrupt on timeout
+         */
+        SEPARATE_THREAD
+    }
+}
+```
+
+**Usage Examples:**
+
+```java
+class TimeoutTest {
+    
+    @Test
+    @Timeout(5) // 5 seconds

+# Dynamic Tests
+
+Runtime test generation capabilities that allow creating tests programmatically during execution. Dynamic tests enable flexible test scenarios based on runtime data and conditions.
+
+## Imports
+
+```java
+import org.junit.jupiter.api.*;
+import java.util.stream.Stream;
+import java.util.Collection;
+import static org.junit.jupiter.api.Assertions.*;
+import static org.junit.jupiter.api.DynamicTest.dynamicTest;
+import static org.junit.jupiter.api.DynamicContainer.dynamicContainer;
+```
+
+## Capabilities
+
+### Test Factory Annotation
+
+Mark methods that generate dynamic tests at runtime.
+
+```java { .api }
+/**
+ * Marks a method as a factory for dynamic tests
+ * Method must return Stream, Collection, Iterable, or Iterator of DynamicNode
+ */
+@Target(ElementType.METHOD)
+@Retention(RetentionPolicy.RUNTIME)
+@interface TestFactory {
+}
+```
+
+### Dynamic Test Creation
+
+Create individual dynamic test instances.
+
+```java { .api }
+/**
+ * A dynamically generated test
+ */
+class DynamicTest extends DynamicNode {
+    /**
+     * Create a dynamic test with display name and executable

+
+### Dynamic Container Creation
+
+Group related dynamic tests in containers.
+
+```java { .api }
+/**
+ * A container for dynamic tests or other containers
+ */
+class DynamicContainer extends DynamicNode {
+    /**
+     * Create a dynamic container with display name and children

+                    .mapToObj(i -> DynamicTest.dynamicTest(
+                        category + " Test " + i,
+                        () -> {
+                            assertNotNull(category);
+                            assertTrue(i > 0);
+                        }
+                    ))
+            ));
+    }
+}
+```
+
+### Dynamic Node Base
+
+Base class for all dynamic test elements.
+
+```java { .api }
+/**
+ * Base class for dynamic tests and containers
+ */
+abstract class DynamicNode {
+    /**
+     * Get display name
+     */
+    String getDisplayName();
+    
+    /**
+     * Get test source URI
+     */
+    Optional<URI> getTestSourceUri();
+}
+```
+
+### Named Interface
+
+Interface for providing names to test components.
+
+```java { .api }
+/**
+ * Interface for named test components
+ */
+interface Named {
+    /**
+     * Get the name
+     */
+    String getName();
+    
+    /**
+     * Create Named instance with given name and payload
+     */
+    static <T> Named<T> of(String name, T payload);
+}
+
+/**
+ * Named executable for dynamic test creation
+ */
+interface NamedExecutable extends Named {
+    /**
+     * Get the executable
+     */
+    Executable getExecutable(); 
+    
+    /**
+     * Create NamedExecutable with name and executable
+     */
+    static NamedExecutable of(String name, Executable executable);
+}
+```
+
+**Usage Examples:**
+
+```java
+class NamedTestExample {
+    
+    @TestFactory
+    Stream<DynamicTest> namedTests() {
+        List<Named<String>> testData = Arrays.asList(
+            Named.of("First test", "alpha"),
+            Named.of("Second test", "beta"),
+            Named.of("Third test", "gamma")
+        );
+        
+        return testData.stream()
+            .map(namedData -> DynamicTest.dynamicTest(
+                namedData.getName(),
+                () -> {
+                    String value = namedData.getPayload();
+                    assertNotNull(value);
+                    assertTrue(value.length() > 3);
+                }
+            ));
+    }
+    
+    @TestFactory
+    Stream<DynamicTest> namedExecutableTests() {
+        List<NamedExecutable> executables = Arrays.asList(
+            NamedExecutable.of("Test addition", () -> assertEquals(4, 2 + 2)),
+            NamedExecutable.of("Test subtraction", () -> assertEquals(0, 2 - 2)),
+            NamedExecutable.of("Test multiplication", () -> assertEquals(4, 2 * 2))
+        );
+        
+        return executables.stream()
+            .map(namedExec -> DynamicTest.dynamicTest(
+                namedExec.getName(),
+                namedExec.getExecutable()
+            ));
+    }
+}
+```
+
+### Complex Dynamic Test Scenarios
+
+Advanced patterns for dynamic test generation.
+
+**Database-driven Tests:**
+
+```java

+    }
+    
+    @TestFactory
+    Stream<DynamicNode> testUsersByRole() {
+        UserRepository repository = new UserRepository();
+        Map<String, List<User>> usersByRole = repository.findAll().stream()
+            .collect(Collectors.groupingBy(User::getRole));

+# Extensions and Lifecycle
+
+JUnit Jupiter's powerful extension model allows customizing test behavior, dependency injection, and integration with external frameworks. Extensions provide hooks into the test lifecycle and enable sophisticated test customizations.
+
+## Imports
+
+```java
+import org.junit.jupiter.api.extension.*;
+import static org.junit.jupiter.api.Assertions.*;
+```
+
+## Capabilities
+
+### Extension Registration
+
+Register extensions declaratively or programmatically.
+
+```java { .api }
+/**
+ * Register extensions declaratively on test classes and methods
+ */
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@Repeatable(ExtendWith.List.class)
+@interface ExtendWith {
+    /**
+     * Extension classes to register
+     */
+    Class<? extends Extension>[] value();
+    
+    @Target({ElementType.TYPE, ElementType.METHOD})
+    @Retention(RetentionPolicy.RUNTIME)
+    @interface List {
+        ExtendWith[] value();
+    }
+}
+
+/**
+ * Register extension instance via static field
+ */
+@Target(ElementType.FIELD)
+@Retention(RetentionPolicy.RUNTIME)
+@interface RegisterExtension {
+}
+
+/**
+ * Base extension interface - marker interface for all extensions
+ */
+interface Extension {
+}
+```
+
+**Usage Examples:**
+
+```java
+// Declarative registration
+@ExtendWith(DatabaseExtension.class)
+@ExtendWith(MockitoExtension.class)
+class MyTest {
+    
+    @Test
+    void testWithExtensions() {
+        // Extensions are active
+    }
+}
+
+// Programmatic registration
+class MyTest {
+    
+    @RegisterExtension
+    static DatabaseExtension database = new DatabaseExtension("testdb");
+    
+    @RegisterExtension
+    MockServerExtension mockServer = new MockServerExtension(8080);
+    
+    @Test
+    void testWithProgrammaticExtensions() {
+        // Extensions configured and active
+    }
+}
+```
+
+### Lifecycle Callback Extensions
+
+Hook into test lifecycle events.
+
+```java { .api }
+/**
+ * Callback before all tests in container
+ */
+interface BeforeAllCallback extends Extension {
+    void beforeAll(ExtensionContext context) throws Exception;
+}
+
+/**
+ * Callback before each test method
+ */
+interface BeforeEachCallback extends Extension {
+    void beforeEach(ExtensionContext context) throws Exception;
+}
+
+/**
+ * Callback before test method execution (after @BeforeEach)
+ */
+interface BeforeTestExecutionCallback extends Extension {
+    void beforeTestExecution(ExtensionContext context) throws Exception;
+}
+
+/**
+ * Callback after test method execution (before @AfterEach)
+ */
+interface AfterTestExecutionCallback extends Extension {
+    void afterTestExecution(ExtensionContext context) throws Exception;
+}
+
+/**
+ * Callback after each test method
+ */
+interface AfterEachCallback extends Extension {
+    void afterEach(ExtensionContext context) throws Exception;
+}
+
+/**
+ * Callback after all tests in container
+ */
+interface AfterAllCallback extends Extension {
+    void afterAll(ExtensionContext context) throws Exception;
+}
+```
+
+**Usage Example:**
+
+```java
+class TimingExtension implements BeforeTestExecutionCallback, AfterTestExecutionCallback {
+    
+    private static final String START_TIME = "start time";
+    
+    @Override
+    public void beforeTestExecution(ExtensionContext context) throws Exception {
+        getStore(context).put(START_TIME, System.currentTimeMillis());
+    }
+    
+    @Override
+    public void afterTestExecution(ExtensionContext context) throws Exception {
+        Method testMethod = context.getRequiredTestMethod();
+        long startTime = getStore(context).remove(START_TIME, long.class);
+        long duration = System.currentTimeMillis() - startTime;
+        
+        System.out.printf("Method [%s] took %s ms.%n", testMethod.getName(), duration);
+    }
+    
+    private ExtensionContext.Store getStore(ExtensionContext context) {
+        return context.getStore(ExtensionContext.Namespace.create(getClass(), context.getRequiredTestMethod()));
+    }
+}
+
+@ExtendWith(TimingExtension.class)
+class TimedTest {
+    
+    @Test
+    void testThatTakesTime() throws InterruptedException {
+        Thread.sleep(100);
+        assertTrue(true);
+    }
+}
+```
+
+### Parameter Resolution Extensions
+
+Inject custom parameters into test methods and constructors.
+
+```java { .api }
+/**
+ * Resolve parameters for test methods and constructors
+ */
+interface ParameterResolver extends Extension {
+    /**
+     * Check if this resolver supports the parameter
+     */
+    boolean supportsParameter(ParameterContext parameterContext, ExtensionContext extensionContext) 
+        throws ParameterResolutionException;
+    
+    /**
+     * Resolve the parameter value
+     */
+    Object resolveParameter(ParameterContext parameterContext, ExtensionContext extensionContext) 
+        throws ParameterResolutionException;
+}
+
+/**
+ * Parameter context information
+ */
+interface ParameterContext {
+    Parameter getParameter();
+    int getIndex();
+    Optional<Object> getTarget();
+    boolean isAnnotated(Class<? extends Annotation> annotationType);
+    <A extends Annotation> Optional<A> findAnnotation(Class<A> annotationType);
+    <A extends Annotation> List<A> findRepeatableAnnotations(Class<A> annotationType);
+}
+
+/**
+ * Type-based parameter resolver base class
+ */
+abstract class TypeBasedParameterResolver<T> implements ParameterResolver {
+    private final Class<T> parameterType;
+    
+    protected TypeBasedParameterResolver(Class<T> parameterType) {
+        this.parameterType = parameterType;
+    }
+    
+    @Override
+    public final boolean supportsParameter(ParameterContext parameterContext, ExtensionContext extensionContext) {
+        return parameterType.equals(parameterContext.getParameter().getType());
+    }
+    
+    @Override
+    public final Object resolveParameter(ParameterContext parameterContext, ExtensionContext extensionContext) {
+        return resolveParameter(extensionContext);
+    }
+    
+    /**
+     * Resolve parameter of the supported type
+     */
+    public abstract T resolveParameter(ExtensionContext extensionContext);
+}
+```
+
+**Usage Examples:**
+
+```java
+class DatabaseConnectionResolver implements ParameterResolver {
+    
+    @Override
+    public boolean supportsParameter(ParameterContext parameterContext, ExtensionContext extensionContext) {
+        return parameterContext.getParameter().getType() == Connection.class;
+    }
+    
+    @Override
+    public Object resolveParameter(ParameterContext parameterContext, ExtensionContext extensionContext) {
+        return createDatabaseConnection();
+    }
+    
+    private Connection createDatabaseConnection() {
+        // Create and return database connection
+        return DriverManager.getConnection("jdbc:h2:mem:test");
+    }
+}
+
+class TempDirectoryResolver extends TypeBasedParameterResolver<Path> {
+    
+    public TempDirectoryResolver() {
+        super(Path.class);
+    }
+    
+    @Override
+    public Path resolveParameter(ExtensionContext extensionContext) {
+        return Files.createTempDirectory("junit-test");
+    }
+}
+
+@ExtendWith({DatabaseConnectionResolver.class, TempDirectoryResolver.class})
+class DatabaseTest {
+    
+    @Test
+    void testWithInjectedParameters(Connection connection, Path tempDir) {
+        assertNotNull(connection);
+        assertNotNull(tempDir);
+        assertTrue(Files.exists(tempDir));
+    }
+}
+```
+
+### Conditional Execution Extensions
+
+Control when tests should be executed.
+
+```java { .api }
+/**
+ * Determine whether test should be executed
+ */
+interface ExecutionCondition extends Extension {
+    /**
+     * Evaluate execution condition
+     */
+    ConditionEvaluationResult evaluateExecutionCondition(ExtensionContext context);
+}
+
+/**
+ * Result of condition evaluation
+ */
+class ConditionEvaluationResult {
+    /**
+     * Create enabled result
+     */
+    static ConditionEvaluationResult enabled(String reason);
+    
+    /**
+     * Create disabled result
+     */
+    static ConditionEvaluationResult disabled(String reason);
+    
+    /**
+     * Check if execution is disabled
+     */
+    boolean isDisabled();
+    
+    /**
+     * Get reason for the result
+     */
+    Optional<String> getReason();
+}
+```
+
+**Usage Example:**
+
+```java
+class SystemPropertyCondition implements ExecutionCondition {
+    
+    @Override
+    public ConditionEvaluationResult evaluateExecutionCondition(ExtensionContext context) {
+        Optional<SystemProperty> annotation = context.getElement()
+            .map(element -> element.getAnnotation(SystemProperty.class));
+            
+        if (annotation.isPresent()) {
+            SystemProperty systemProperty = annotation.get();
+            String actualValue = System.getProperty(systemProperty.name());
+            
+            if (systemProperty.value().equals(actualValue)) {
+                return ConditionEvaluationResult.enabled("System property matches");
+            } else {
+                return ConditionEvaluationResult.disabled(
+                    String.format("System property [%s] does not match expected value [%s]", 
+                        systemProperty.name(), systemProperty.value()));
+            }
+        }
+        
+        return ConditionEvaluationResult.enabled("No system property condition");
+    }
+}
+
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@ExtendWith(SystemPropertyCondition.class)
+@interface SystemProperty {
+    String name();
+    String value();
+}
+
+class ConditionalTest {
+    
+    @Test
+    @SystemProperty(name = "env", value = "test")
+    void testOnlyInTestEnvironment() {
+        // Only runs when system property env=test
+        assertTrue(true);
+    }
+}
+```
+
+### Test Instance Extensions
+
+Control test instance creation and lifecycle.
+
+```java { .api }
+/**
+ * Create test instances
+ */
+interface TestInstanceFactory extends Extension {
+    /**
+     * Create test instance
+     */
+    Object createTestInstance(TestInstanceFactoryContext factoryContext, ExtensionContext extensionContext) 
+        throws TestInstantiationException;
+}
+
+/**
+ * Test instance factory context
+ */
+interface TestInstanceFactoryContext {

+
+/**
+ * Callback before test instance destruction
+ */
+interface TestInstancePreDestroyCallback extends Extension {
+    void preDestroyTestInstance(ExtensionContext context) throws Exception;

+```
+
+**Usage Example:**
+
+```java
+class DependencyInjectionExtension implements TestInstancePostProcessor {
+    
+    @Override
+    public void postProcessTestInstance(Object testInstance, ExtensionContext context) throws Exception {
+        Class<?> testClass = testInstance.getClass();
+        
+        for (Field field : testClass.getDeclaredFields()) {
+            if (field.isAnnotationPresent(Inject.class)) {

+    void testWithInjectedService() {
+        assertNotNull(userService);
+        // Use injected service
+    }
+}
+```
+
+### Exception Handling Extensions
+
+Handle test execution exceptions.
+
+```java { .api }
+/**
+ * Handle exceptions thrown during test execution
+ */

+
+```java
+import org.junit.jupiter.api.*;
+import org.junit.jupiter.params.ParameterizedTest;
+import org.junit.jupiter.params.provider.*;
+```
+
+Common static imports for assertions:
+
+```java
+import static org.junit.jupiter.api.Assertions.*;
+import static org.junit.jupiter.api.Assumptions.*;
+```
+
+## Basic Usage
+
+```java
+import org.junit.jupiter.api.*;
+import static org.junit.jupiter.api.Assertions.*;
+
+class CalculatorTest {
+
+    @Test
+    @DisplayName("Addition should work correctly")
+    void testAddition() {
+        Calculator calc = new Calculator();
+        assertEquals(5, calc.add(2, 3));
+        assertNotNull(calc);
+    }
+
+    @BeforeEach
+    void setUp() {
+        // Setup before each test
+        System.out.println("Setting up test");
+    }
+
+    @AfterEach
+    void tearDown() {
+        // Cleanup after each test
+        System.out.println("Cleaning up test");
+    }
+
+    @ParameterizedTest
+    @ValueSource(ints = {1, 2, 3, 4, 5})

+// Core assertions
+static void assertEquals(Object expected, Object actual);
+static void assertTrue(boolean condition);
+static void assertThrows(Class<T> expectedType, Executable executable);
+static void assertAll(Executable... executables);
+
+// Assumptions
+static void assumeTrue(boolean assumption);
+static void assumingThat(boolean assumption, Executable executable);
+```
+
+[Assertions and Assumptions](./assertions.md)
+
+### Parameterized Tests
+
+Advanced parameterized testing with multiple data sources, argument conversion, and aggregation for data-driven test scenarios.
+
+```java { .api }
+@ParameterizedTest
+@ValueSource(ints = {1, 2, 3})
+@CsvSource({"1,John", "2,Jane"})
+@MethodSource("argumentProvider")
+void parameterizedTest(int value, String name);
+```
+
+[Parameterized Tests](./parameterized-tests.md)
+
+### Extensions and Lifecycle
+
+Powerful extension model for customizing test behavior, dependency injection, and integrating with external frameworks.
+
+```java { .api }
+@ExtendWith(MyExtension.class)
+@RegisterExtension
+static MyExtension extension = new MyExtension();
+
+interface Extension { }
+interface BeforeAllCallback extends Extension;
+interface ParameterResolver extends Extension;
+```
+
+[Extensions](./extensions.md)
+
+### Conditional Execution
+
+Rich set of conditions for controlling test execution based on operating system, JRE version, system properties, and custom conditions.
+
+```java { .api }
+@EnabledOnOs(OS.LINUX)
+@DisabledOnJre(JRE.JAVA_8)
+@EnabledIfSystemProperty(named = "env", matches = "prod")
+@EnabledIf("customCondition")
+```
+
+[Conditional Execution](./conditional-execution.md)
+
+### Dynamic Tests
+
+Runtime test generation and nested test organization for complex test scenarios and hierarchical test structure.
+
+```java { .api }
+@TestFactory
+Stream<DynamicTest> dynamicTests();
+
+static DynamicTest dynamicTest(String displayName, Executable executable);
+static DynamicContainer dynamicContainer(String displayName, Stream<DynamicNode> children);
+```
+
+[Dynamic Tests](./dynamic-tests.md)
+
+### Parallel Execution and Resource Management
+
+Configuration for parallel test execution, resource locking, and temporary file management for performance optimization.
+
+```java { .api }
+@Execution(ExecutionMode.CONCURRENT)
+@ResourceLock("database")
+@TempDir
+Path tempDirectory;
+```
+
+[Parallel Execution](./parallel-execution.md)
+
+## Types

+# Parallel Execution and Resource Management
+
+Configuration for parallel test execution, resource locking, and temporary file management. JUnit Jupiter provides fine-grained control over test concurrency and resource access.
+
+## Imports
+
+```java
+import org.junit.jupiter.api.parallel.*;
+import org.junit.jupiter.api.io.TempDir;
+import java.nio.file.Path;
+import static org.junit.jupiter.api.Assertions.*;
+```
+
+## Capabilities
+
+### Parallel Execution Configuration
+
+Control concurrent execution of tests and test classes.
+
+```java { .api }
+/**
+ * Configure parallel execution mode for tests
+ */
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface Execution {
+    /**
+     * Execution mode for this test or test class
+     */
+    ExecutionMode value();
+}
+
+/**
+ * Execution mode enumeration
+ */
+enum ExecutionMode {
+    /**
+     * Execute in same thread as parent
+     */
+    SAME_THREAD,
+    
+    /**
+     * Execute concurrently with other tests (if parallel execution enabled)
+     */
+    CONCURRENT
+}
+```
+
+**Usage Examples:**
+
+```java
+// Enable concurrent execution for entire test class
+@Execution(ExecutionMode.CONCURRENT)
+class ParallelTest {
+    
+    @Test
+    void test1() {
+        // Runs concurrently with other tests
+        performIndependentOperation();
+    }
+    
+    @Test
+    void test2() {
+        // Runs concurrently with other tests
+        performAnotherIndependentOperation();
+    }
+    
+    @Test
+    @Execution(ExecutionMode.SAME_THREAD)
+    void sequentialTest() {
+        // Runs sequentially despite class-level concurrent setting
+        performSequentialOperation();
+    }
+}
+
+// Mixed execution modes
+class MixedExecutionTest {
+    
+    @Test
+    @Execution(ExecutionMode.CONCURRENT)
+    void concurrentTest1() {
+        // Runs concurrently
+    }
+    
+    @Test
+    @Execution(ExecutionMode.CONCURRENT)
+    void concurrentTest2() {
+        // Runs concurrently
+    }
+    
+    @Test
+    void defaultTest() {
+        // Uses default execution mode
+    }
+}
+```
+
+### Test Isolation
+
+Force sequential execution for tests that require isolation.
+
+```java { .api }
+/**
+ * Force sequential execution in separate classloader
+ */
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface Isolated {
+}
+```
+
+**Usage Example:**
+
+```java
+@Isolated
+class IsolatedTest {
+    
+    @Test
+    void testThatModifiesGlobalState() {
+        System.setProperty("test.mode", "isolated");
+        // Test runs in isolation
+    }
+    
+    @Test
+    void anotherIsolatedTest() {
+        // Also runs in isolation
+    }
+}
+
+class RegularTest {
+    
+    @Test
+    @Isolated
+    void isolatedMethod() {
+        // Only this method runs in isolation
+    }
+    
+    @Test
+    void regularMethod() {
+        // Regular execution
+    }
+}
+```
+
+### Resource Locking
+
+Coordinate access to shared resources across concurrent tests.
+
+```java { .api }
+/**
+ * Lock access to a shared resource
+ */
+@Target({ElementType.TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@Repeatable(ResourceLocks.class)
+@interface ResourceLock {
+    /**
+     * Resource identifier
+     */
+    String value();
+    
+    /**
+     * Access mode for the resource
+     */
+    ResourceAccessMode mode() default ResourceAccessMode.READ_WRITE;
+

+
+### Standard Resources
+
+Pre-defined resource identifiers for common shared resources.
+
+```java { .api }
+/**
+ * Standard resource constants
+ */
+class Resources {
+    /**
+     * Global resource lock
+     */
+    public static final String GLOBAL = "GLOBAL";

+        
+        Locale.setDefault(original);
+    }
+}
+```
+
+### Custom Resource Locks Provider
+
+Programmatically provide resource locks based on test context.
+
+```java { .api }
+/**

+# Parameterized Tests
+
+Advanced parameterized testing capabilities that allow running the same test logic with different sets of arguments. JUnit Jupiter provides multiple ways to supply test arguments with support for custom conversion and aggregation.
+
+## Imports
+
+```java
+import org.junit.jupiter.params.ParameterizedTest;
+import org.junit.jupiter.params.provider.*;
+import org.junit.jupiter.params.aggregator.*;
+import org.junit.jupiter.params.converter.*;
+import static org.junit.jupiter.api.Assertions.*;
+```
+
+## Capabilities
+
+### Parameterized Test Annotation
+
+Core annotation for defining parameterized tests.
+
+```java { .api }
+/**
+ * Marks a method as a parameterized test with multiple argument sources
+ */
+@Target(ElementType.METHOD)
+@Retention(RetentionPolicy.RUNTIME)
+@interface ParameterizedTest {
+    /**
+     * Custom name pattern for parameterized test invocations
+     */
+    String name() default "[{index}] {arguments}";
+    
+    /**
+     * How to handle argument count mismatches
+     */
+    ArgumentCountValidationMode argumentCountValidationMode() default ArgumentCountValidationMode.STRICT;
+}
+
+enum ArgumentCountValidationMode {
+    STRICT,      // Fail if parameter count doesn't match
+    LENIENT,     // Allow missing parameters (null values)
+    IGNORE       // Ignore extra arguments
+}
+```
+
+**Basic Usage:**
+
+```java
+@ParameterizedTest
+@ValueSource(ints = {1, 2, 3})
+void testWithValueSource(int argument) {
+    assertTrue(argument > 0);
+}
+
+@ParameterizedTest(name = "Run {index}: testing with value {0}")
+@ValueSource(strings = {"apple", "banana", "cherry"})
+void testWithCustomName(String fruit) {
+    assertNotNull(fruit);
+    assertTrue(fruit.length() > 3);
+}
+```
+
+### Value Sources
+
+Simple argument sources for primitive types and strings.
+
+```java { .api }
+/**
+ * Array of literal values as arguments
+ */
+@Target({ElementType.ANNOTATION_TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@ArgumentsSource(ValueArgumentsProvider.class)
+@interface ValueSource {
+    short[] shorts() default {};
+    byte[] bytes() default {};
+    int[] ints() default {};
+    long[] longs() default {};
+    float[] floats() default {};
+    double[] doubles() default {};
+    char[] chars() default {};
+    boolean[] booleans() default {};
+    String[] strings() default {};
+    Class<?>[] classes() default {};
+}
+
+/**
+ * Container for multiple value sources
+ */
+@Target({ElementType.ANNOTATION_TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@interface ValueSources {
+    ValueSource[] value();
+}
+```
+
+**Usage Examples:**
+
+```java
+@ParameterizedTest
+@ValueSource(ints = {1, 2, 3, 4, 5})
+void testNumbers(int number) {
+    assertTrue(number > 0 && number < 6);
+}
+
+@ParameterizedTest
+@ValueSource(strings = {"", "  "})
+void testBlankStrings(String input) {
+    assertTrue(input.isBlank());
+}
+
+@ParameterizedTest
+@ValueSource(booleans = {true, false})
+void testBooleans(boolean value) {
+    // Test both true and false cases
+    assertNotNull(Boolean.valueOf(value));
+}
+
+@ParameterizedTest
+@ValueSource(classes = {String.class, Integer.class, List.class})
+void testClasses(Class<?> clazz) {
+    assertNotNull(clazz);
+    assertNotNull(clazz.getName());
+}
+```
+
+### Null and Empty Sources
+
+Special argument sources for null and empty values.

+@Target({ElementType.ANNOTATION_TYPE, ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@NullSource
+@EmptySource
+@interface NullAndEmptySource {
+}
+```
+
+**Usage Examples:**
+
+```java

+    // Test with null, empty, blank, and valid strings
+    String result = StringUtils.clean(input);
+    // Assert based on input type
+}
+
+@ParameterizedTest
+@NullAndEmptySource
+@ValueSource(strings = {"apple", "banana"})
+void testStringProcessing(String input) {
+    // Test null, empty, and actual values

+    }
+}
+
+@ParameterizedTest

+void testUserData(String username, String email, boolean active) {
+    assertNotNull(username);
+    assertTrue(email.contains("@"));
+    // active can be true or false
+}
+```
+
+### Method Sources
+
+Arguments from static methods.

+interface ArgumentsProvider {
+    /**
+     * Provide arguments for parameterized test
+     */
+    Stream<? extends Arguments> provideArguments(ExtensionContext context) throws Exception;
+}
+
+/**
+ * Base class for annotation-based providers

+    /**
+     * Accept annotation for configuration
+     */
+    protected abstract void accept(T annotation);
+}
+```
+
+**Usage Example:**
+
+```java
+@Target(ElementType.METHOD)
+@Retention(RetentionPolicy.RUNTIME)
+@ArgumentsSource(RandomIntegerProvider.class)
+@interface RandomIntegers {
+    int count() default 10;

+@RandomIntegers(count = 5, min = 1, max = 10)
+void testWithRandomIntegers(int value) {
+    assertTrue(value >= 1 && value <= 10);
+}
+```
+
+### Argument Conversion
+
+Convert string arguments to other types automatically or with custom converters.
+
+```java { .api }

+    String value();
+}
+
+/**
+ * Argument converter interface
+ */
+interface ArgumentConverter<S, T> {
+    /**
+     * Convert source argument to target type
+     */

+    public final T convert(S source, ParameterContext context) throws ArgumentConversionException {
+        return convert(source, context.getParameter().getType());
+    }
+    
+    /**
+     * Convert source to target type
+     */
+    protected abstract T convert(S source, Class<?> targetType) throws ArgumentConversionException;
+}
+
+/**
+ * Typed converter with type safety

+        this.sourceType = sourceType;
+        this.targetType = targetType; 
+    }
+}
+```
+
+**Usage Examples:**
+
+```java
+@ParameterizedTest
+@ValueSource(strings = {"2023-01-01", "2023-12-31"})
+void testDates(@JavaTimeConversionPattern("yyyy-MM-dd") LocalDate date) {

+void testPersonConversion(@ConvertWith(StringToPersonConverter.class) Person person) {
+    assertNotNull(person.getName());
+    assertTrue(person.getAge() > 0);
+}
+```
+
+### Argument Aggregation
+
+Aggregate multiple arguments into complex objects.
+
+```java { .api }
+/**
+ * Custom argument aggregator annotation
+ */
+@Target(ElementType.PARAMETER)
+@Retention(RetentionPolicy.RUNTIME)
+@interface AggregateWith {
+    /**

+}
+
+/**
+ * Arguments aggregator interface
+ */
+interface ArgumentsAggregator {
+    /**
+     * Aggregate arguments into single object
+     */
+    Object aggregateArguments(ArgumentsAccessor accessor, ParameterContext context) 
+        throws ArgumentsAggregationException;
+}
+
+/**
+ * Arguments accessor for retrieving individual arguments
+ */
+interface ArgumentsAccessor {

+    String role = arguments.getString(2);
+    
+    Person person = new Person(name, age, role);
+    assertNotNull(person);
+}
+```
+
+### Arguments Utility
+
+Utility class for creating argument sets programmatically.
+
+```java { .api }
+/**
+ * Factory for creating Arguments instances
+ */
+interface Arguments {
+    /**
+     * Create Arguments from array of objects
+     */
+    static Arguments of(Object... arguments);
+    
+    /**
+     * Get arguments as object array
+     */
+    Object[] get();
+}
+```
+
+**Usage Example:**
+
+```java
+static Stream<Arguments> complexArgumentProvider() {
+    return Stream.of(
+        Arguments.of(1, "apple", true, new Person("John", 25)),
+        Arguments.of(2, "banana", false, new Person("Jane", 30)),

+# Configuration Management
+
+Babel configuration loading, validation, and management system supporting various config file formats, runtime options, and plugin/preset resolution. Provides both full and partial configuration loading for different use cases.
+
+## Capabilities
+
+### Options Loading
+
+Load and resolve complete Babel configuration from various sources.
+
+```typescript { .api }
+/**
+ * Load complete Babel options synchronously
+ * @param opts - Input options to merge with config file settings
+ * @returns Resolved configuration object or null if no config found
+ */
+function loadOptionsSync(opts?: InputOptions): ResolvedConfig | null;
+
+/**
+ * Load complete Babel options asynchronously
+ * @param opts - Input options to merge with config file settings
+ * @returns Promise resolving to resolved configuration or null
+ */
+function loadOptionsAsync(opts?: InputOptions): Promise<ResolvedConfig | null>;
+
+/**
+ * Load complete Babel options with callback (legacy API, deprecated in Babel 8)
+ * @param opts - Input options to merge with config file settings
+ * @param callback - Callback function receiving error and resolved config
+ */
+function loadOptions(
+  opts: InputOptions,
+  callback: (err: Error | null, config: ResolvedConfig | null) => void
+): void;
+function loadOptions(
+  callback: (err: Error | null, config: ResolvedConfig | null) => void
+): void;
+
+interface ResolvedConfig {
+  /** Resolved plugins with their options */
+  plugins: Array<ConfigItem>;
+  /** Resolved presets with their options */
+  presets: Array<ConfigItem>;
+  /** Parser options */
+  parserOpts: ParserOptions;
+  /** Generator options */
+  generatorOpts: GeneratorOptions;
+  /** All other resolved options */
+  [key: string]: any;
+}
+```
+
+**Usage Examples:**
+
+```typescript
+import { loadOptionsSync, loadOptionsAsync } from "@babel/core";
+
+// Load configuration from babel.config.js and .babelrc files
+const config = loadOptionsSync({
+  cwd: "/path/to/project",
+  filename: "src/app.js",
+  envName: "production"
+});
+
+if (config) {
+  console.log("Plugins:", config.plugins.map(p => p.name));
+  console.log("Presets:", config.presets.map(p => p.name));
+  console.log("Parser options:", config.parserOpts);
+}
+
+// Override config file settings
+const customConfig = loadOptionsSync({
+  presets: ["@babel/preset-env"],
+  plugins: ["@babel/plugin-transform-runtime"],
+  targets: "> 0.25%, not dead"
+});
+
+// Async loading
+const asyncConfig = await loadOptionsAsync({
+  cwd: process.cwd(),
+  configFile: "./babel.config.json",
+  envName: process.env.NODE_ENV
+});
+```
+
+### Partial Configuration
+
+Load partial configuration for advanced use cases where full resolution isn't needed.
+
+```typescript { .api }
+/**
+ * Load partial Babel configuration synchronously
+ * @param opts - Input options for partial resolution
+ * @returns Partial configuration object or null
+ */
+function loadPartialConfigSync(opts?: InputOptions): PartialConfig | null;
+
+/**
+ * Load partial Babel configuration asynchronously
+ * @param opts - Input options for partial resolution
+ * @returns Promise resolving to partial configuration or null
+ */
+function loadPartialConfigAsync(opts?: InputOptions): Promise<PartialConfig | null>;
+
+/**
+ * Load partial configuration with callback (legacy API, deprecated in Babel 8)
+ * @param opts - Input options for partial resolution
+ * @param callback - Callback function receiving error and partial config
+ */
+function loadPartialConfig(
+  opts: InputOptions,
+  callback: (err: Error | null, config: PartialConfig | null) => void
+): void;
+function loadPartialConfig(
+  callback: (err: Error | null, config: PartialConfig | null) => void
+): void;
+
+interface PartialConfig {
+  /** Resolved options (may be null if no valid config) */
+  options: ResolvedConfig | null;
+  /** Loaded config file information */
+  config?: {
+    filepath: string;
+    dirname: string;
+    options: any;
+  };
+  /** Loaded .babelrc file information */
+  babelrc?: {
+    filepath: string;
+    dirname: string;
+    options: any;
+  };
+  /** Whether this config ignores the file */
+  hasFilesystemConfig(): boolean;
+}
+```
+
+**Usage Examples:**
+
+```typescript
+import { loadPartialConfigSync } from "@babel/core";
+
+// Check if a file should be processed
+const partialConfig = loadPartialConfigSync({
+  filename: "src/components/Button.tsx",
+  cwd: "/path/to/project"
+});
+
+if (partialConfig) {
+  if (partialConfig.hasFilesystemConfig()) {
+    console.log("File has Babel config");
+    
+    if (partialConfig.config) {
+      console.log("Config file:", partialConfig.config.filepath);
+    }
+    
+    if (partialConfig.babelrc) {
+      console.log("Babelrc file:", partialConfig.babelrc.filepath);
+    }
+    
+    // Use resolved options
+    if (partialConfig.options) {
+      console.log("Resolved plugins:", partialConfig.options.plugins.length);
+    }
+  } else {
+    console.log("No Babel config found for this file");
+  }
+}
+```
+
+### Configuration Items
+
+Create and manage individual plugin and preset configuration items.
+
+```typescript { .api }
+/**
+ * Create configuration item synchronously
+ * @param target - Plugin/preset function, module name, or path
+ * @param options - Options to pass to the plugin/preset
+ * @returns Configuration item or null if invalid
+ */
+function createConfigItemSync(
+  target: PluginTarget,
+  options?: ConfigItemOptions
+): ConfigItem<PluginAPI> | null;
+
+/**
+ * Create configuration item asynchronously
+ * @param target - Plugin/preset function, module name, or path
+ * @param options - Options to pass to the plugin/preset
+ * @returns Promise resolving to configuration item or null
+ */
+function createConfigItemAsync(
+  target: PluginTarget,
+  options?: ConfigItemOptions
+): Promise<ConfigItem<PluginAPI> | null>;
+
+/**
+ * Create configuration item with callback (legacy API, deprecated in Babel 8)
+ * @param target - Plugin/preset function, module name, or path
+ * @param options - Options to pass to the plugin/preset
+ * @param callback - Callback function receiving error and config item
+ */
+function createConfigItem(
+  target: PluginTarget,
+  options: ConfigItemOptions,
+  callback: (err: Error | null, item: ConfigItem<PluginAPI> | null) => void
+): void;
+
+type PluginTarget = 
+  | string 
+  | PluginFunction 
+  | PresetFunction
+  | [string, any]
+  | [PluginFunction, any]
+  | [PresetFunction, any];
+
+interface ConfigItemOptions {
+  /** Directory context for resolution */  
+  dirname?: string;
+  /** Item type: "plugin" or "preset" */
+  type?: "plugin" | "preset";
+}
+
+interface ConfigItem<T = PluginAPI> {
+  /** Resolved plugin/preset function */
+  value: T;
+  /** Configuration options passed to the plugin/preset */
+  options: any;
+  /** Directory where the plugin/preset was resolved */
+  dirname: string;
+  /** Name of the plugin/preset */
+  name?: string;
+  /** Full file path if resolved from file */
+  file?: {
+    request: string;
+    resolved: string;
+  };
+}
+```
+
+**Usage Examples:**
+
+```typescript
+import { createConfigItemSync } from "@babel/core";
+
+// Create plugin config item
+const pluginItem = createConfigItemSync("@babel/plugin-transform-runtime", {
+  dirname: "/path/to/project",
+  type: "plugin"
+});
+
+if (pluginItem) {
+  console.log("Plugin name:", pluginItem.name);
+  console.log("Plugin options:", pluginItem.options);
+  console.log("Resolved from:", pluginItem.file?.resolved);
+}
+
+// Create preset config item with options
+const presetItem = createConfigItemSync(
+  ["@babel/preset-env", {
+    targets: "> 0.25%, not dead",
+    useBuiltIns: "usage",
+    corejs: 3
+  }],
+  {
+    dirname: process.cwd(),
+    type: "preset"  
+  }
+);
+
+// Create from function
+const customPlugin = function(babel) {
+  return {
+    visitor: {
+      Identifier(path) {
+        console.log("Found identifier:", path.node.name);
+      }
+    }
+  };
+};
+
+const customItem = createConfigItemSync(customPlugin, {
+  dirname: __dirname,
+  type: "plugin"
+});
+```
+
+## Configuration File Support
+
+Babel supports various configuration file formats:
+
+```typescript { .api }
+interface ConfigFileOptions {
+  /** Path to specific config file, or false to disable */
+  configFile?: string | false;
+  /** Enable/disable .babelrc file loading */
+  babelrc?: boolean;
+  /** Root directory for config file search */
+  root?: string;
+  /** Current working directory */
+  cwd?: string;
+  /** Override root mode: "root", "upward", or "upward-optional" */
+  rootMode?: "root" | "upward" | "upward-optional";
+}
+```
+
+**Supported Config Files:**
+
+- `babel.config.json` - Project-wide configuration
+- `babel.config.js` - Project-wide with JavaScript
+- `babel.config.mjs` - Project-wide with ES modules
+- `babel.config.cjs` - Project-wide with CommonJS
+- `.babelrc` - File-relative configuration
+- `.babelrc.json` - File-relative JSON
+- `.babelrc.js` - File-relative JavaScript
+- `package.json` - Babel field in package.json
+
+**Usage Examples:**
+
+```typescript
+import { loadOptionsSync } from "@babel/core";
+
+// Use specific config file
+const config1 = loadOptionsSync({
+  configFile: "./babel.production.js",
+  cwd: "/path/to/project"
+});
+
+// Disable config file loading
+const config2 = loadOptionsSync({
+  configFile: false,
+  plugins: ["@babel/plugin-transform-arrow-functions"]
+});
+
+// Disable .babelrc files
+const config3 = loadOptionsSync({
+  babelrc: false,
+  presets: ["@babel/preset-env"]
+});
+
+// Search from different root
+const config4 = loadOptionsSync({
+  root: "/different/root",
+  rootMode: "upward",
+  filename: "src/app.js"
+});
+```
+
+## Environment-based Configuration
+
+Configure Babel behavior based on environment:
+
+```typescript { .api }
+interface EnvironmentOptions {
+  /** Environment name (defaults to BABEL_ENV || NODE_ENV || "development") */
+  envName?: string;
+  /** Caller metadata for conditional configuration */
+  caller?: CallerMetadata;
+}
+
+interface CallerMetadata {
+  /** Name of the calling tool */
+  name: string;
+  /** Version of the calling tool */
+  version?: string;
+  /** Whether the caller supports ES modules */
+  supportsStaticESM?: boolean;
+  /** Whether the caller supports dynamic imports */
+  supportsDynamicImport?: boolean;
+  /** Whether the caller supports top-level await */
+  supportsTopLevelAwait?: boolean;
+  /** Additional caller-specific properties */
+  [key: string]: any;
+}
+```
+
+**Usage Examples:**
+
+```typescript
+import { loadOptionsSync } from "@babel/core";
+
+// Load development configuration
+const devConfig = loadOptionsSync({
+  envName: "development",
+  caller: {
+    name: "webpack",
+    version: "5.0.0",
+    supportsStaticESM: true
+  }
+});
+
+// Load production configuration
+const prodConfig = loadOptionsSync({
+  envName: "production",
+  caller: {
+    name: "rollup", 
+    version: "2.0.0",
+    supportsDynamicImport: true
+  }
+});
+
+// Override environment
+process.env.NODE_ENV = "test";
+const testConfig = loadOptionsSync({
+  envName: "testing", // Overrides NODE_ENV
+  filename: "test/example.spec.js"
+});
+```
+
+## Advanced Configuration Patterns
+
+### Conditional Configuration
+
+```javascript
+// babel.config.js
+module.exports = function(api) {
+  // Cache configuration based on environment
+  api.cache.using(() => process.env.NODE_ENV);
+  
+  const presets = ["@babel/preset-env"];
+  const plugins = [];
+  
+  // Add plugins based on environment
+  if (api.env("development")) {
+    plugins.push("react-refresh/babel");
+  }
+  
+  // Add plugins based on caller
+  if (api.caller(caller => caller?.name === "webpack")) {
+    plugins.push("@babel/plugin-syntax-dynamic-import");
+  }
+  
+  return { presets, plugins };
+};
+```
+
+### Programmatic Configuration
+
+```typescript
+import { loadOptionsSync, transformSync } from "@babel/core";
+
+// Build configuration programmatically
+const baseConfig = loadOptionsSync({
+  presets: ["@babel/preset-env"],
+  configFile: false
+});
+
+// Extend with additional plugins
+const extendedConfig = {
+  ...baseConfig,
+  plugins: [
+    ...baseConfig.plugins,
+    ["@babel/plugin-transform-runtime", { corejs: 3 }]
+  ]
+};
+
+// Use extended configuration
+const result = transformSync(code, extendedConfig);
+```
+
+## Error Handling
+
+Configuration functions may throw errors for invalid configurations:
+
+```typescript
+import { loadOptionsSync, createConfigItemSync } from "@babel/core";
+
+try {
+  const config = loadOptionsSync({
+    plugins: ["non-existent-plugin"]
+  });
+} catch (error) {
+  if (error.code === "BABEL_UNKNOWN_PLUGIN") {
+    console.error("Unknown plugin:", error.message);
+  }
+}
+
+try {
+  const item = createConfigItemSync("invalid-plugin", {
+    dirname: "/nonexistent"
+  });
+} catch (error) {
+  console.error("Failed to create config item:", error.message);
+}
+```

+# Babel Core
+
+Babel Core is the core compiler for Babel, providing programmatic APIs for JavaScript code transformation, parsing, and configuration. It enables developers to transpile modern JavaScript code into backward-compatible versions, parse JavaScript into Abstract Syntax Trees (ASTs), and configure the transformation process through plugins and presets.
+
+## Package Information
+
+- **Package Name**: @babel/core
+- **Package Type**: npm
+- **Language**: TypeScript
+- **Installation**: `npm install @babel/core`
+
+## Core Imports
+
+```typescript
+import * as babel from "@babel/core";
+```
+
+For specific functions:
+
+```typescript
+import { 
+  transform, 
+  transformSync, 
+  parse, 
+  parseSync, 
+  loadOptions,
+  createConfigItem,
+  types,
+  traverse,
+  template,
+  type PluginPass,
+  type Visitor,
+  type NodePath,
+  type Scope
+} from "@babel/core";
+```
+
+CommonJS:
+
+```javascript
+const babel = require("@babel/core");
+const { transform, parse, loadOptions } = require("@babel/core");
+```
+
+## Basic Usage
+
+```typescript
+import { transformSync, parseSync } from "@babel/core";
+
+// Transform JavaScript code
+const result = transformSync(`
+  const arrow = () => console.log("Hello");
+  class MyClass {
+    method() { return 42; }
+  }
+`, {
+  presets: ["@babel/preset-env"],
+  plugins: ["@babel/plugin-transform-arrow-functions"]
+});
+
+console.log(result.code);
+// Output: Transpiled ES5 compatible code
+
+// Parse JavaScript to AST
+const ast = parseSync(`
+  function hello() {
+    return "world";
+  }
+`, {
+  sourceType: "module",
+  plugins: ["jsx", "typescript"]
+});
+
+console.log(ast.type); // "File"
+```
+
+## Architecture
+
+Babel Core is built around several key components:
+
+- **Transformation Engine**: Core APIs (`transform`, `transformSync`, `transformAsync`) that apply plugins and presets to JavaScript code
+- **Parser Interface**: Wrapper around @babel/parser (`parse`, `parseSync`, `parseAsync`) for AST generation
+- **Configuration System**: Option loading and validation (`loadOptions`, `loadPartialConfig`) with support for config files
+- **Plugin/Preset Management**: Configuration item creation and resolution (`createConfigItem`, `resolvePlugin`, `resolvePreset`)
+- **File Processing**: File-based transformation APIs (`transformFile`, `transformFileSync`, `transformFileAsync`)
+- **AST Processing**: Direct AST transformation (`transformFromAst`, `transformFromAstSync`, `transformFromAstAsync`)
+
+## Browser Compatibility
+
+Babel Core includes browser-compatible variants for client-side usage:
+
+- **File system operations** are replaced with browser-compatible alternatives
+- **Config file resolution** is modified for browser environments  
+- **Transform file APIs** (`transformFile*`) use alternative implementations that don't rely on Node.js file system
+- **Module resolution** adapts to browser module loading patterns
+
+The package automatically uses browser-compatible versions when bundled for web environments through the `browser` field in package.json.
+
+## Capabilities

+# Code Parsing
+
+JavaScript parsing functionality that converts source code into Abstract Syntax Trees (ASTs) using Babel's parser. Provides both synchronous and asynchronous parsing with extensive configuration options for different JavaScript dialects and syntax extensions.
+
+## Capabilities
+
+### String Parsing
+
+Parse JavaScript code from strings into Babel ASTs.
+
+```typescript { .api }
+/**
+ * Parse JavaScript code synchronously
+ * @param code - JavaScript source code to parse
+ * @param opts - Parsing options including syntax plugins and parser settings
+ * @returns Babel AST (File node) or null if parsing fails
+ */
+function parseSync(code: string, opts?: InputOptions): ParseResult | null;
+
+/**
+ * Parse JavaScript code asynchronously
+ * @param code - JavaScript source code to parse
+ * @param opts - Parsing options including syntax plugins and parser settings
+ * @returns Promise resolving to Babel AST (File node) or null
+ */
+function parseAsync(code: string, opts?: InputOptions): Promise<ParseResult | null>;
+
+/**
+ * Parse JavaScript code with callback (legacy API, deprecated in Babel 8)
+ * @param code - JavaScript source code to parse
+ * @param opts - Parsing options
+ * @param callback - Callback function receiving error and AST result
+ */
+function parse(
+  code: string,
+  opts: InputOptions | null | undefined,
+  callback: FileParseCallback
+): void;
+function parse(code: string, callback: FileParseCallback): void;
+
+type ParseResult = import("@babel/types").File;
+type FileParseCallback = (err: Error | null, ast: ParseResult | null) => void;
+```
+
+**Usage Examples:**
+
+```typescript
+import { parseSync, parseAsync } from "@babel/core";
+
+// Basic parsing
+const ast = parseSync(`
+  function hello(name) {
+    return \`Hello \${name}!\`;
+  }
+`, {
+  sourceType: "module"
+});
+
+console.log(ast.type); // "File"
+console.log(ast.program.type); // "Program"
+console.log(ast.program.body[0].type); // "FunctionDeclaration"
+
+// Parsing with TypeScript syntax
+const tsAst = parseSync(`
+  interface User {
+    name: string;
+    age: number;
+  }
+  
+  const user: User = { name: "Alice", age: 30 };
+`, {
+  sourceType: "module",
+  plugins: ["typescript"]
+});
+
+// Parsing with JSX syntax
+const jsxAst = parseSync(`
+  const Component = () => {
+    return <div>Hello World</div>;
+  };
+`, {
+  sourceType: "module", 
+  plugins: ["jsx"]
+});
+
+// Asynchronous parsing
+const asyncAst = await parseAsync(`
+  async function getData() {
+    const response = await fetch('/api/data');
+    return response.json();
+  }
+`, {
+  sourceType: "module",
+  plugins: ["asyncGenerators"]
+});
+```
+
+### Parser Configuration
+
+Configure the parsing behavior with various options:
+
+```typescript { .api }
+interface ParseOptions {
+  /** Source type: "script", "module", or "unambiguous" (default: "script") */
+  sourceType?: "script" | "module" | "unambiguous";
+  /** Filename for error reporting and source maps */
+  filename?: string;
+  /** Parser-specific options */
+  parserOpts?: ParserOptions;
+  /** Environment name for conditional parsing */
+  envName?: string;
+  /** Current working directory */
+  cwd?: string;
+  /** Root directory for config resolution */
+  root?: string;
+}
+
+interface ParserOptions {
+  /** Syntax plugins to enable */
+  plugins?: ParserPlugin[];
+  /** Source type override */
+  sourceType?: "script" | "module" | "unambiguous";
+  /** Allow import/export outside modules */
+  allowImportExportEverywhere?: boolean;
+  /** Allow return statements outside functions */
+  allowReturnOutsideFunction?: boolean;
+  /** Allow undeclared exports */
+  allowUndeclaredExports?: boolean;
+  /** Create parent references on AST nodes */
+  createParenthesizedExpressions?: boolean;
+  /** Track error recovery information */
+  errorRecovery?: boolean;
+  /** Add location information to nodes */
+  ranges?: boolean;
+  /** Include token list in result */
+  tokens?: boolean;
+  /** Strict mode parsing */
+  strictMode?: boolean;
+  /** Start line number (default: 1) */
+  startLine?: number;
+  /** Start column number (default: 0) */
+  startColumn?: number;
+}
+
+type ParserPlugin = 
+  | "jsx" 
+  | "typescript" 
+  | "flow" 
+  | "decorators" 
+  | "classProperties"
+  | "classPrivateProperties"
+  | "classPrivateMethods" 
+  | "classStaticBlock"
+  | "asyncGenerators"
+  | "functionBind"

+      dts?: boolean; 
+      disallowAmbiguousJSXLike?: boolean;
+      allowNamespaces?: boolean;
+    }];
+```
+
+**Usage Examples:**
+
+```typescript
+import { parseSync } from "@babel/core";
+
+// TypeScript with decorators
+const decoratorAst = parseSync(`
+  @Component({
+    selector: 'app-example'
+  })
+  class ExampleComponent {
+    @Input() value: string;
+    
+    @HostListener('click')
+    onClick() {}
+  }
+`, {
+  sourceType: "module",
+  plugins: [
+    "typescript",
+    ["decorators", { decoratorsBeforeExport: true }]
+  ]
+});
+
+// Flow type annotations
+const flowAst = parseSync(`
+  type User = {
+    name: string,
+    age: number
+  };
+  
+  function greetUser(user: User): string {
+    return \`Hello \${user.name}\`;
+  }
+`, {
+  sourceType: "module",
+  plugins: [["flow", { all: true }]]
+});
+
+// Modern JavaScript features
+const modernAst = parseSync(`
+  class APIClient {
+    #baseUrl = 'https://api.example.com';
+    
+    async getData() {
+      const response = await fetch(\`\${this.#baseUrl}/data\`);
+      return response?.json() ?? null;
+    }
+    
+    static {
+      console.log('APIClient initialized');
+    }
+  }
+`, {
+  sourceType: "module",
+  plugins: [
+    "classPrivateProperties",
+    "classPrivateMethods", 
+    "classStaticBlock",
+    "nullishCoalescingOperator",
+    "optionalChaining",
+    "topLevelAwait"
+  ]
+});
+```
+
+## AST Structure
+
+The parsing result is a Babel AST with the following structure:
+
+```typescript { .api }
+interface File {
+  type: "File";
+  /** The program node containing all top-level statements */
+  program: Program;
+  /** Comments found in the source code */
+  comments: Comment[];
+  /** Tokens if tokens: true was specified */
+  tokens?: Token[];
+  /** Source location information */
+  loc?: SourceLocation;
+  /** Start and end positions */
+  start?: number;
+  end?: number;
+}
+
+interface Program {
+  type: "Program";
+  /** Top-level statements and declarations */
+  body: Statement[];
+  /** Directive nodes (like "use strict") */
+  directives: Directive[];
+  /** Source type that was detected/specified */
+  sourceType: "script" | "module";
+  /** Source location information */
+  loc?: SourceLocation;
+}
+
+interface SourceLocation {
+  /** Starting position */
+  start: Position;
+  /** Ending position */
+  end: Position;
+  /** Original filename */
+  filename?: string;
+  /** Identifier name for anonymous sources */
+  identifierName?: string;
+}
+
+interface Position {
+  /** Line number (1-based) */
+  line: number;
+  /** Column number (0-based) */
+  column: number;
+  /** Character index in source */
+  index?: number;
+}
+
+interface Comment {
+  type: "CommentBlock" | "CommentLine";
+  /** Comment text content */
+  value: string;
+  /** Source location */
+  loc?: SourceLocation;
+  /** Start and end positions */
+  start?: number;
+  end?: number;
+}
+```
+
+## Working with ASTs
+
+Common patterns for working with parsed ASTs:
+
+```typescript
+import { parseSync } from "@babel/core";
+import traverse from "@babel/traverse";
+import * as t from "@babel/types";
+
+const code = `
+  function add(a, b) {
+    return a + b;
+  }
+  
+  const multiply = (x, y) => x * y;
+`;
+
+const ast = parseSync(code, { sourceType: "module" });
+
+// Traverse the AST
+traverse(ast, {
+  // Visit all function declarations
+  FunctionDeclaration(path) {
+    console.log("Function name:", path.node.id.name);
+    console.log("Parameter count:", path.node.params.length);
+  },
+  
+  // Visit all arrow functions
+  ArrowFunctionExpression(path) {
+    console.log("Arrow function found");
+    
+    // Convert to regular function
+    const params = path.node.params;
+    const body = t.isExpression(path.node.body) 
+      ? t.blockStatement([t.returnStatement(path.node.body)])
+      : path.node.body;
+      
+    path.replaceWith(
+      t.functionExpression(null, params, body)
+    );
+  }
+});
+
+// Check node types
+traverse(ast, {
+  enter(path) {
+    if (t.isIdentifier(path.node)) {
+      console.log("Identifier:", path.node.name);
+    }
+    if (t.isStringLiteral(path.node)) {
+      console.log("String:", path.node.value);
+    }
+  }
+});
+```
+
+## Error Handling
+
+Parse functions may throw errors for invalid syntax:
+
+```typescript
+import { parseSync } from "@babel/core";
+
+try {
+  const ast = parseSync("const x = ;", {

+  });
+} catch (error) {
+  if (error.code === "BABEL_PARSE_ERROR") {
+    console.error("Parse error:", error.message);
+    console.error("Location:", error.loc); // { line: 1, column: 10 }
+    console.error("Position:", error.pos); // Character position
+  }
+}
+
+// Handle missing plugins
+try {
+  const tsAst = parseSync("const x: number = 42;", {
+    sourceType: "module"
+    // Missing "typescript" plugin
+  });
+} catch (error) {
+  console.error("Missing plugin:", error.message);
+  // "This experimental syntax requires enabling the parser plugin: 'typescript'"
+}
+```
+
+## Integration with Other Babel APIs
+
+Parsed ASTs can be used with other Babel functions:
+
+```typescript
+import { parseSync, transformFromAstSync, traverse } from "@babel/core";
+
+// Parse -> Modify -> Transform workflow
+const code = `const greeting = name => \`Hello \${name}\`;`;
+
+// 1. Parse to AST
+const ast = parseSync(code, { 
+  sourceType: "module",
+  plugins: ["templateLiterals"]
+});
+
+// 2. Modify AST
+traverse(ast, {
+  TemplateLiteral(path) {
+    // Convert template literal to concatenation
+    // This is just an example - in practice use appropriate plugins
+  }
+});
+
+// 3. Transform to code
+const result = transformFromAstSync(ast, code, {
+  presets: ["@babel/preset-env"]
+});
+
+console.log(result.code);

+# Code Transformation
+
+Core JavaScript transformation functionality for converting modern JavaScript code into backward-compatible versions using Babel plugins and presets. Supports string-based, file-based, and AST-based transformation workflows.
+
+## Capabilities
+
+### String Transformation
+
+Transform JavaScript code from strings with full plugin and preset support.
+
+```typescript { .api }
+/**
+ * Transform JavaScript code synchronously
+ * @param code - JavaScript source code to transform
+ * @param opts - Transformation options including plugins, presets, and parser settings
+ * @returns Transformation result with code, source map, and optional AST
+ */
+function transformSync(code: string, opts?: InputOptions): FileResult | null;
+
+/**
+ * Transform JavaScript code asynchronously  
+ * @param code - JavaScript source code to transform
+ * @param opts - Transformation options including plugins, presets, and parser settings
+ * @returns Promise resolving to transformation result
+ */
+function transformAsync(code: string, opts?: InputOptions): Promise<FileResult | null>;
+
+/**
+ * Transform JavaScript code with callback (legacy API, deprecated in Babel 8)
+ * @param code - JavaScript source code to transform
+ * @param opts - Transformation options
+ * @param callback - Callback function receiving error and result
+ */
+function transform(
+  code: string,
+  opts: InputOptions | null | undefined,
+  callback: FileResultCallback
+): void;
+function transform(code: string, callback: FileResultCallback): void;
+
+type FileResultCallback = (err: Error | null, result: FileResult | null) => void;
+```
+
+**Usage Examples:**
+
+```typescript
+import { transformSync, transformAsync } from "@babel/core";
+
+// Synchronous transformation
+const result = transformSync(`
+  const getMessage = () => "Hello World";
+  class User {
+    constructor(name) {
+      this.name = name;
+    }
+  }
+`, {
+  presets: ["@babel/preset-env"],
+  plugins: ["@babel/plugin-transform-arrow-functions", "@babel/plugin-transform-classes"]
+});
+
+console.log(result.code);
+// Output: ES5 compatible code
+
+// Asynchronous transformation
+const asyncResult = await transformAsync(`
+  import { useState } from 'react';
+  export const Component = () => <div>Hello</div>;
+`, {
+  presets: ["@babel/preset-react", "@babel/preset-env"],
+  filename: "component.jsx"
+});
+
+console.log(asyncResult.code);
+```
+
+### File Transformation
+
+Transform JavaScript files directly from the filesystem.
+
+```typescript { .api }
+/**
+ * Transform JavaScript file synchronously
+ * @param filename - Path to JavaScript file to transform
+ * @param opts - Transformation options (filename will be added automatically)
+ * @returns Transformation result with code, source map, and optional AST
+ */
+function transformFileSync(filename: string, opts?: InputOptions): FileResult | null;
+
+/**
+ * Transform JavaScript file asynchronously
+ * @param filename - Path to JavaScript file to transform  
+ * @param opts - Transformation options (filename will be added automatically)
+ * @returns Promise resolving to transformation result
+ */
+function transformFileAsync(filename: string, opts?: InputOptions): Promise<FileResult | null>;
+
+/**
+ * Transform JavaScript file with callback
+ * @param filename - Path to JavaScript file to transform
+ * @param opts - Transformation options
+ * @param callback - Callback function receiving error and result
+ */
+function transformFile(
+  filename: string,
+  opts: InputOptions | null | undefined,
+  callback: FileResultCallback
+): void;
+function transformFile(filename: string, callback: FileResultCallback): void;
+```
+
+**Usage Examples:**
+
+```typescript
+import { transformFileSync, transformFileAsync } from "@babel/core";
+
+// Synchronous file transformation
+const result = transformFileSync("./src/app.js", {
+  presets: ["@babel/preset-env"],
+  sourceMaps: true
+});
+
+if (result) {
+  console.log("Transformed:", result.code);
+  console.log("Source map:", result.map);
+}
+
+// Asynchronous file transformation
+const asyncResult = await transformFileAsync("./src/component.tsx", {
+  presets: ["@babel/preset-typescript", "@babel/preset-react"],
+  plugins: ["@babel/plugin-transform-runtime"]
+});
+```
+
+### AST Transformation
+
+Transform JavaScript code from existing Abstract Syntax Trees (ASTs).
+
+```typescript { .api }
+/**
+ * Transform from AST synchronously
+ * @param ast - Babel AST (File or Program node)
+ * @param code - Original source code string for source map generation
+ * @param opts - Transformation options
+ * @returns Transformation result with code, source map, and optional AST
+ */
+function transformFromAstSync(
+  ast: AstRoot, 
+  code: string, 
+  opts?: InputOptions
+): FileResult | null;
+
+/**
+ * Transform from AST asynchronously
+ * @param ast - Babel AST (File or Program node)
+ * @param code - Original source code string for source map generation
+ * @param opts - Transformation options
+ * @returns Promise resolving to transformation result
+ */
+function transformFromAstAsync(
+  ast: AstRoot, 
+  code: string, 
+  opts?: InputOptions
+): Promise<FileResult | null>;
+
+/**
+ * Transform from AST with callback (legacy API, deprecated in Babel 8)
+ * @param ast - Babel AST (File or Program node)
+ * @param code - Original source code string
+ * @param opts - Transformation options
+ * @param callback - Callback function receiving error and result
+ */
+function transformFromAst(
+  ast: AstRoot,
+  code: string,
+  opts: InputOptions | null | undefined,
+  callback: FileResultCallback
+): void;
+function transformFromAst(
+  ast: AstRoot, 
+  code: string, 
+  callback: FileResultCallback
+): void;
+
+type AstRoot = import("@babel/types").File | import("@babel/types").Program;
+```
+
+**Usage Examples:**
+
+```typescript
+import { parseSync, transformFromAstSync } from "@babel/core";
+
+// Parse then transform
+const code = `const x = () => 42;`;
+const ast = parseSync(code, {
+  sourceType: "module",
+  plugins: ["jsx"]
+});
+
+const result = transformFromAstSync(ast, code, {
+  presets: ["@babel/preset-env"]
+});
+
+console.log(result.code);
+// Output: Transformed code from the AST
+
+// Modify AST before transformation
+import traverse from "@babel/traverse";
+import * as t from "@babel/types";
+
+traverse(ast, {
+  ArrowFunctionExpression(path) {
+    // Convert arrow function to regular function
+    path.replaceWith(
+      t.functionExpression(null, path.node.params, 
+        t.blockStatement([t.returnStatement(path.node.body)])
+      )
+    );
+  }
+});
+
+const modifiedResult = transformFromAstSync(ast, code, {
+  presets: ["@babel/preset-env"]
+});
+```
+
+## Transformation Result
+
+All transformation functions return a `FileResult` object containing the transformed code and metadata.
+
+```typescript { .api }
+interface FileResult {
+  /** Transformed JavaScript code, null if transformation was skipped */
+  code: string | null;
+  /** Source map object for debugging, null if source maps disabled */
+  map: object | null;
+  /** AST object if ast: true option was provided, null otherwise */
+  ast: object | null;
+  /** Metadata collected during transformation including plugin information */
+  metadata: {
+    /** Modules that were processed during transformation */
+    modules?: {
+      imports: Array<{
+        source: string;
+        imported: string[];
+        specifiers: any[];
+      }>;
+      exports: Array<{
+        exported: string[];
+        specifiers: any[];
+      }>;
+    };
+    /** List of external helper functions that were used */
+    externalHelpers?: string[];
+    /** Plugin-specific metadata */
+    [pluginName: string]: any;
+  };
+}
+```
+
+## Common Transformation Options
+
+Key options for controlling the transformation process:
+
+```typescript { .api }
+interface TransformationOptions {
+  /** Plugins to apply during transformation */
+  plugins?: Array<string | [string, any] | PluginFunction | [PluginFunction, any]>;
+  /** Presets to apply during transformation (applied before plugins) */
+  presets?: Array<string | [string, any] | PresetFunction | [PresetFunction, any]>;
+  /** Include AST in result (default: false) */
+  ast?: boolean;
+  /** Generate source maps: false, true, "inline", or "both" */
+  sourceMaps?: boolean | "inline" | "both";
+  /** Compact output: true, false, or "auto" (default: "auto") */
+  compact?: boolean | "auto";
+  /** Environment name for conditional configuration */
+  envName?: string;
+  /** Override source filename in source maps and error messages */
+  filename?: string;
+  /** Parser options passed to @babel/parser */
+  parserOpts?: {
+    sourceType?: "script" | "module" | "unambiguous";
+    allowImportExportEverywhere?: boolean;
+    allowReturnOutsideFunction?: boolean;
+    plugins?: string[];
+    strictMode?: boolean;
+    ranges?: boolean;
+    tokens?: boolean;
+  };
+  /** Generator options passed to @babel/generator */
+  generatorOpts?: {
+    /** Retain parentheses around expressions */
+    retainLines?: boolean;
+    /** Compact whitespace */
+    compact?: boolean;
+    /** Number of spaces for indentation */
+    indent?: number;
+    /** Quote style: "single" or "double" */
+    quotes?: "single" | "double";
+  };
+}
+```
+
+## Error Handling
+
+Transformation functions may throw errors for various reasons:
+
+```typescript
+import { transformSync } from "@babel/core";
+
+try {
+  const result = transformSync("invalid syntax {{", {
+    presets: ["@babel/preset-env"]
+  });
+} catch (error) {
+  if (error.code === "BABEL_PARSE_ERROR") {
+    console.error("Parse error:", error.message);
+    console.error("Location:", error.loc);
+  } else if (error.code === "BABEL_TRANSFORM_ERROR") {
+    console.error("Transform error:", error.message);
+    console.error("Plugin:", error.plugin);
+  } else {
+    console.error("Other error:", error.message);
+  }
+}

+# Utilities and Constants
+
+Helper functions, constants, and re-exported APIs from the Babel ecosystem. Includes version information, file extensions, environment detection, plugin resolution, and access to the complete Babel toolchain.
+
+## Capabilities
+
+### Version and Constants
+
+Version information and recommended file extensions for Babel processing.
+
+```typescript { .api }
+/**
+ * Current version of @babel/core package
+ */
+const version: string;
+
+/**
+ * Recommended set of compilable file extensions
+ * Not used in @babel/core directly, but meant as an easy source for tooling
+ */
+const DEFAULT_EXTENSIONS: readonly [".js", ".jsx", ".es6", ".es", ".mjs", ".cjs"];
+```
+
+**Usage Examples:**
+
+```typescript
+import { version, DEFAULT_EXTENSIONS } from "@babel/core";
+
+console.log("Babel version:", version); // "7.26.10"
+
+console.log("Default extensions:", DEFAULT_EXTENSIONS);
+// [".js", ".jsx", ".es6", ".es", ".mjs", ".cjs"]
+
+// Use in build tools
+const shouldProcess = (filename) => {
+  return DEFAULT_EXTENSIONS.some(ext => filename.endsWith(ext));
+};
+
+console.log(shouldProcess("app.js")); // true
+console.log(shouldProcess("styles.css")); // false
+```
+
+### Environment Detection
+
+Detect and resolve the current Babel environment.
+
+```typescript { .api }
+/**
+ * Get the current Babel environment name
+ * @param defaultValue - Default environment if none specified (default: "development")
+ * @returns Environment name from BABEL_ENV, NODE_ENV, or default value
+ */
+function getEnv(defaultValue?: string): string;
+```
+
+**Usage Examples:**
+
+```typescript
+import { getEnv } from "@babel/core";
+
+// Without environment variables set
+console.log(getEnv()); // "development"
+console.log(getEnv("production")); // "production"
+
+// With NODE_ENV=test
+process.env.NODE_ENV = "test";
+console.log(getEnv()); // "test"
+
+// With BABEL_ENV=staging (takes precedence over NODE_ENV)
+process.env.BABEL_ENV = "staging";
+console.log(getEnv()); // "staging"
+
+// Use in configuration
+const isProd = getEnv() === "production";
+const isDev = getEnv() === "development";
+```
+
+### Plugin and Preset Resolution
+
+Resolve plugin and preset file paths (legacy APIs for backward compatibility).
+
+```typescript { .api }
+/**
+ * Resolve plugin file path (legacy API)
+ * @param name - Plugin name or path
+ * @param dirname - Directory to resolve from
+ * @returns Resolved file path
+ */
+function resolvePlugin(name: string, dirname: string): string;
+
+/**
+ * Resolve preset file path (legacy API)
+ * @param name - Preset name or path  
+ * @param dirname - Directory to resolve from
+ * @returns Resolved file path
+ */
+function resolvePreset(name: string, dirname: string): string;
+```
+
+**Usage Examples:**
+
+```typescript
+import { resolvePlugin, resolvePreset } from "@babel/core";
+
+// Resolve official plugins
+const pluginPath = resolvePlugin("@babel/plugin-transform-arrow-functions", __dirname);
+console.log(pluginPath); // "/path/to/node_modules/@babel/plugin-transform-arrow-functions/lib/index.js"
+
+// Resolve official presets
+const presetPath = resolvePreset("@babel/preset-env", process.cwd());
+console.log(presetPath); // "/path/to/node_modules/@babel/preset-env/lib/index.js"
+
+// Resolve relative paths
+const localPlugin = resolvePlugin("./plugins/custom-plugin", __dirname);
+console.log(localPlugin); // "/current/dir/plugins/custom-plugin.js"
+
+// Use in plugin loading
+function loadPlugin(name, dirname) {
+  try {
+    const pluginPath = resolvePlugin(name, dirname);
+    return require(pluginPath);
+  } catch (error) {
+    console.error(`Failed to load plugin ${name}:`, error.message);
+  }
+}
+```
+
+### External Helper Generation
+
+Generate external Babel helper functions for runtime optimization.
+
+```typescript { .api }
+/**
+ * Build external helper functions as a single module
+ * @param whitelist - Array of helper names to include, or undefined for all
+ * @param outputType - Output format: "global", "umd", "var", or function
+ * @returns Generated helper code as string
+ */
+function buildExternalHelpers(
+  whitelist?: string[],
+  outputType?: "global" | "umd" | "var" | ((name: string) => string)
+): string;
+```
+
+**Usage Examples:**
+
+```typescript
+import { buildExternalHelpers } from "@babel/core";
+
+// Generate all helpers as global variables
+const allHelpers = buildExternalHelpers(undefined, "global");
+console.log(allHelpers);
+// Output: Global helper functions for all Babel runtime helpers
+
+// Generate specific helpers only
+const specificHelpers = buildExternalHelpers([
+  "_classCallCheck",
+  "_createClass", 
+  "_inherits"
+], "umd");
+console.log(specificHelpers);
+// Output: UMD module with class-related helpers only
+
+// Generate with custom output format
+const customHelpers = buildExternalHelpers(
+  ["_asyncToGenerator", "_awaitAsyncGenerator"],
+  (name) => `window.BabelHelpers.${name.slice(1)}`
+);
+console.log(customHelpers);
+// Output: Helpers assigned to window.BabelHelpers
+
+// Use in build process
+const fs = require("fs");
+const helpers = buildExternalHelpers(undefined, "umd");
+fs.writeFileSync("dist/babel-helpers.js", helpers);
+```
+
+## Re-exported APIs
+
+Babel Core re-exports several essential APIs from other Babel packages for convenience.
+
+### Babel Types
+
+Complete AST node types and utilities from @babel/types.
+
+```typescript { .api }
+/**
+ * Complete @babel/types API for AST manipulation
+ * Includes all node builders, validators, and utilities
+ */
+import * as types from "@babel/types";
+
+// Re-exported as namespace
+export * as types from "@babel/types";
+```
+
+**Usage Examples:**
+
+```typescript
+import { types as t } from "@babel/core";
+// or: import * as t from "@babel/core";
+
+// Create AST nodes
+const identifier = t.identifier("myVariable");
+const stringLiteral = t.stringLiteral("Hello World");
+const callExpression = t.callExpression(
+  t.identifier("console.log"),
+  [stringLiteral]
+);
+
+// Validate node types
+if (t.isIdentifier(identifier)) {
+  console.log("Name:", identifier.name);
+}
+
+if (t.isCallExpression(callExpression)) {
+  console.log("Callee:", callExpression.callee);
+  console.log("Arguments:", callExpression.arguments);
+}
+
+// Build complex structures
+const functionDeclaration = t.functionDeclaration(
+  t.identifier("greet"),
+  [t.identifier("name")],
+  t.blockStatement([
+    t.returnStatement(
+      t.templateLiteral(
+        [
+          t.templateElement({ raw: "Hello " }, false),
+          t.templateElement({ raw: "!" }, true)
+        ],
+        [t.identifier("name")]
+      )
+    )
+  ])
+);
+```
+
+### Babel Traverse
+
+AST traversal utilities from @babel/traverse.
+
+```typescript { .api }
+/**
+ * Default traverse function for AST traversal
+ */
+export { default as traverse } from "@babel/traverse";
+
+/**
+ * Node path type for AST traversal
+ */
+export type { NodePath } from "@babel/traverse";
+
+/**
+ * Scope information type
+ */
+export type { Scope } from "@babel/traverse";
+
+/**
+ * Visitor pattern type for AST traversal
+ */
+export type Visitor<S = unknown> = import("@babel/traverse").Visitor<S>;
+```
+
+**Usage Examples:**
+
+```typescript
+import { traverse, parseSync, types as t } from "@babel/core";
+
+const code = `
+  function calculate(a, b) {
+    const result = a + b;
+    return result;
+  }
+`;
+
+const ast = parseSync(code, { sourceType: "module" });
+
+// Basic traversal
+traverse(ast, {
+  enter(path) {
+    console.log("Entering:", path.node.type);
+  },
+  
+  exit(path) {
+    console.log("Exiting:", path.node.type);
+  }
+});
+
+// Specific node visitors
+traverse(ast, {
+  FunctionDeclaration(path) {
+    console.log("Function:", path.node.id.name);
+    console.log("Parameters:", path.node.params.map(p => p.name));
+  },
+  
+  VariableDeclarator(path) {
+    if (t.isIdentifier(path.node.id)) {
+      console.log("Variable:", path.node.id.name);
+    }
+  },
+  
+  BinaryExpression(path) {
+    console.log("Operation:", path.node.operator);
+    console.log("Left:", path.node.left);
+    console.log("Right:", path.node.right);
+  }
+});
+
+// Path manipulation
+traverse(ast, {
+  Identifier(path) {
+    if (path.node.name === "result") {
+      path.node.name = "output";
+    }
+  }
+});
+```
+
+### Babel Template
+
+Template string to AST conversion from @babel/template.
+
+```typescript { .api }
+/**
+ * Template function for converting template strings to AST nodes
+ */
+export { default as template } from "@babel/template";
+```
+
+**Usage Examples:**
+
+```typescript
+import { template, traverse, parseSync } from "@babel/core";
+
+// Create template functions
+const buildRequire = template(`
+  var %%importName%% = require(%%source%%);
+`);
+
+const buildClass = template.statement(`
+  class %%className%% extends %%superClass%% {
+    constructor(%%params%%) {
+      super(%%args%%);
+      %%body%%
+    }
+  }
+`);
+
+// Use templates to generate AST
+const requireNode = buildRequire({
+  importName: t.identifier("lodash"),
+  source: t.stringLiteral("lodash")
+});
+
+const classNode = buildClass({
+  className: t.identifier("MyComponent"),
+  superClass: t.identifier("Component"),
+  params: [t.identifier("props")],
+  args: [t.identifier("props")], 
+  body: [
+    t.expressionStatement(
+      t.assignmentExpression(
+        "=",
+        t.memberExpression(t.thisExpression(), t.identifier("state")),
+        t.objectExpression([])
+      )
+    )
+  ]
+});
+
+// Template with expressions
+const buildConditional = template.expression(`
+  %%test%% ? %%consequent%% : %%alternate%%
+`);
+
+const conditional = buildConditional({
+  test: t.identifier("isLoggedIn"),
+  consequent: t.stringLiteral("Welcome"),
+  alternate: t.stringLiteral("Please log in")
+});
+```
+
+### Babel Parser Token Types
+
+Token types from @babel/parser for advanced parsing use cases.
+
+```typescript { .api }
+/**
+ * Token types from Babel parser
+ */
+export { tokTypes } from "@babel/parser";
+```
+
+**Usage Examples:**
+
+```typescript
+import { tokTypes, parseSync } from "@babel/core";
+
+// Parse with tokens
+const ast = parseSync("const x = 42;", {
+  sourceType: "module",
+  tokens: true
+});
+
+// Check token types
+if (ast.tokens) {
+  ast.tokens.forEach(token => {
+    if (token.type === tokTypes.name) {
+      console.log("Identifier token:", token.value);
+    } else if (token.type === tokTypes.num) {
+      console.log("Number token:", token.value);
+    } else if (token.type === tokTypes._const) {
+      console.log("Const keyword token");
+    }
+  });
+}
+
+// Token type checking
+console.log("Available token types:", Object.keys(tokTypes));
+// ["num", "string", "name", "_const", "_let", "_var", ...]
+```
+
+## File Context Class
+
+The File class provides transformation context and utilities, primarily used in plugin development and advanced transformation scenarios.
+
+```typescript { .api }
+/**
+ * File transformation context class
+ * Provides access to transformation state, metadata, and helper functions
+ */
+export { default as File } from "./transformation/file/file";
+
+class File {
+  /** Transformation options merged from config and parameters */
+  opts: TransformationOptions;
+  /** Variable declarations at file scope */
+  declarations: { [name: string]: import("@babel/types").Identifier };
+  /** Root program path for AST traversal */
+  path: import("@babel/traverse").NodePath<import("@babel/types").Program>;
+  /** Complete file AST including program and metadata */
+  ast: import("@babel/types").File;
+  /** Root scope for the file */
+  scope: import("@babel/traverse").Scope;
+  /** Metadata collected from plugins during transformation */
+  metadata: { [pluginName: string]: any };
+  /** Original source code string */
+  code: string;
+  /** Input source map if available */
+  inputMap: import("convert-source-map").SourceMapConverter | null;
+  
+  /** Hub interface for plugin communication and utilities */
+  hub: FileHub;
+  
+  /** Generate a unique identifier in file scope */
+  generateUid(name: string): import("@babel/types").Identifier;
+  /** Check if identifier is available in file scope */
+  hasIdentifier(name: string): boolean;
+  /** Add import declaration to file */
+  addImport(source: string, importedName: string, localName?: string): import("@babel/types").Identifier;
+  /** Add helper function import */
+  addHelper(name: string): import("@babel/types").Identifier;

+import * as t from "@babel/types";
+
+function myPlugin(): PluginObj {
+  return {
+    visitor: {
+      Program(path, state: PluginPass) {
+        // Access file context
+        const file = state.file;
+        
+        // Get transformation options
+        console.log("Filename:", file.opts.filename);
+        console.log("Source type:", file.opts.sourceType);
+        
+        // Add helper function
+        const helperIdentifier = file.addHelper("classCallCheck");
+        
+        // Generate unique identifier
+        const uniqueId = file.generateUid("temp");
+        
+        // Add metadata for other plugins
+        file.metadata.myPlugin = {
+          processedNodes: 0,
+          addedHelpers: [helperIdentifier.name]
+        };
+        
+        // Access file scope
+        const hasConsole = file.scope.hasBinding("console");
+        console.log("Console available:", hasConsole);
+      },
+      
+      ClassDeclaration(path, state: PluginPass) {
+        const file = state.file;
+        
+        // Increment counter in metadata
+        if (!file.metadata.myPlugin) {
+          file.metadata.myPlugin = { processedNodes: 0 };
+        }
+        file.metadata.myPlugin.processedNodes++;
+        
+        // Create error with file context
+        if (path.node.id === null) {
+          throw file.hub.buildError(
+            path.node,
+            "Anonymous classes are not supported"
+          );
+        }
+      }
+    }
+  };
+}
+```
+
+The File class is essential for plugin authors who need to:
+
+1. **Access transformation context** - filename, options, and configuration
+2. **Manage helper functions** - automatically import required runtime helpers
+3. **Generate unique identifiers** - avoid naming conflicts in transformed code
+4. **Share data between plugins** - using the metadata system
+5. **Handle errors with context** - provide meaningful error messages with location info
+6. **Access file-level scope information** - understand available bindings and references

+# @babel/preset-typescript
+
+@babel/preset-typescript is a Babel preset that enables TypeScript compilation through Babel's plugin pipeline. It configures the necessary plugins to transform TypeScript syntax into JavaScript while maintaining compatibility with Babel's ecosystem and build tools.
+
+## Package Information
+
+- **Package Name**: @babel/preset-typescript
+- **Package Type**: npm
+- **Language**: TypeScript/JavaScript
+- **Installation**: `npm install --save-dev @babel/preset-typescript`
+
+## Core Imports
+
+```javascript
+// babel.config.js
+module.exports = {
+  presets: ['@babel/preset-typescript']
+};
+```
+
+With options:
+
+```javascript
+// babel.config.js
+module.exports = {
+  presets: [
+    ['@babel/preset-typescript', {
+      allowNamespaces: true,
+      onlyRemoveTypeImports: true,
+      optimizeConstEnums: false
+    }]
+  ]
+};
+```
+
+For programmatic usage:
+
+```javascript
+const presetTypescript = require('@babel/preset-typescript').default;
+// or
+import presetTypescript from '@babel/preset-typescript';
+```
+
+## Basic Usage
+
+```javascript
+// babel.config.js - Basic configuration
+module.exports = {
+  presets: ['@babel/preset-typescript']
+};
+```
+
+```javascript
+// babel.config.js - Advanced configuration
+module.exports = {
+  presets: [
+    ['@babel/preset-typescript', {
+      // Allow TypeScript namespaces (default: true)
+      allowNamespaces: true,
+      
+      // Only remove type-only imports (default: true in Babel 8)
+      onlyRemoveTypeImports: true,
+      
+      // Optimize const enum transformations (default: false)
+      optimizeConstEnums: false,
+      
+      // Custom JSX pragma (default: "React")
+      jsxPragma: "React",
+      
+      // Custom JSX fragment pragma (default: "React.Fragment")
+      jsxPragmaFrag: "React.Fragment",
+      
+      // Rewrite TypeScript import extensions (default: false)
+      rewriteImportExtensions: false
+    }]
+  ]
+};
+```
+
+## Architecture
+
+The preset is built around several key components:
+
+- **Core Preset Function**: Main function that configures TypeScript transformation plugins based on options and file extensions
+- **Options Normalizer**: Validates and normalizes configuration options with Babel version-specific behavior
+- **Import Rewriter Plugin**: Optional plugin that rewrites TypeScript import extensions to JavaScript equivalents
+- **Plugin Configuration**: Automatically configures `@babel/plugin-transform-typescript`, JSX syntax support, and CommonJS transformation based on file types
+
+## Capabilities
+
+### Preset Configuration
+
+The main preset function that configures TypeScript transformation for Babel. The preset is exported as the default export wrapped in Babel's `declarePreset` utility.
+
+```typescript { .api }
+// The actual export from @babel/preset-typescript
+const preset: (api: PresetAPI, options?: Options, dirname?: string) => PresetObject;
+
+// From @babel/core
+interface PresetObject {
+  plugins?: PluginList;
+  presets?: PresetList;
+  overrides?: Array<PresetObject>;
+  env?: { [envName: string]: PresetObject };
+  ignore?: IgnoreList;
+  only?: IgnoreList;
+  test?: ConfigApplicableTest;
+  include?: ConfigApplicableTest;
+  exclude?: ConfigApplicableTest;
+}
+
+// The preset returns a configuration with plugins and overrides
+interface PresetResult {
+  plugins: Array<string | [string, any]>;
+  overrides: Array<{
+    test?: RegExp | ((filename?: string) => boolean);
+    sourceType?: "module" | "unambiguous";
+    plugins: Array<string | [string, any]>;
+  }>;
+}
+```
+
+### Options Configuration
+
+Configuration options for customizing TypeScript transformation behavior.
+
+```typescript { .api }
+interface Options {
+  /** Ignore file extensions when determining file type */
+  ignoreExtensions?: boolean;
+  
+  /** Allow TypeScript declare fields (Babel 7 only) */
+  allowDeclareFields?: boolean;
+  
+  /** Allow TypeScript namespaces (default: true) */
+  allowNamespaces?: boolean;
+  
+  /** Disallow ambiguous JSX-like syntax */
+  disallowAmbiguousJSXLike?: boolean;
+  
+  /** JSX pragma to use (default: "React") */
+  jsxPragma?: string;
+  
+  /** JSX fragment pragma (default: "React.Fragment") */
+  jsxPragmaFrag?: string;
+  
+  /** Only remove type-only imports */
+  onlyRemoveTypeImports?: boolean;
+  
+  /** Optimize const enums transformation */
+  optimizeConstEnums?: boolean;
+  
+  /** Rewrite TypeScript import extensions to JavaScript */
+  rewriteImportExtensions?: boolean;
+  
+  /** Handle all file extensions (deprecated in Babel 8) */
+  allExtensions?: boolean;
+  
+  /** Force JSX parsing (deprecated in Babel 8) */
+  isTSX?: boolean;
+}
+```
+
+### Option Normalization
+
+**Internal function** that validates and normalizes preset options. This function is not exported from the main package and is only used internally by the preset.
+
+```typescript { .api }
+// Internal function - NOT exported from @babel/preset-typescript
+// Located in: src/normalize-options.ts
+function normalizeOptions(options?: Options): Required<Options>;
+```
+
+**Usage:** Called internally by the preset to validate and apply default values to user-provided options. This function handles Babel version-specific option validation and provides helpful error messages for deprecated options.
+
+### Import Extension Rewriting
+
+**Internal plugin** that rewrites TypeScript import extensions to JavaScript equivalents. This plugin is not exported from the main package and is only used internally when `rewriteImportExtensions: true` is specified.
+
+```typescript { .api }
+// Internal plugin - NOT exported from @babel/preset-typescript
+// Located in: src/plugin-rewrite-ts-imports.ts
+function pluginRewriteTSImports(): PluginObject;
+
+// From @babel/core
+interface PluginObject {
+  name?: string;
+  visitor: Visitor;
+  pre?: (state: any) => void;
+  post?: (state: any) => void;
+  manipulateOptions?: (opts: any, parserOpts: any) => void;
+}
+```
+
+**Transformation Examples:**
+- `./module.ts` → `./module.js`
+- `./component.tsx` → `./component.jsx` (or `.js` if JSX preservation is disabled)
+- `./module.mts` → `./module.mjs`
+- `./module.cts` → `./module.cjs`
+- `./types.d.ts` → `./types.d.ts` (preserved)
+
+## File Extension Handling
+
+The preset automatically applies different plugin configurations based on file extensions:
+
+### TypeScript Files (.ts)
+
+Standard TypeScript files receive basic TypeScript transformation:
+
+```javascript
+// Configuration applied for .ts files
+{
+  plugins: [
+    ['@babel/plugin-transform-typescript', { 
+      allowNamespaces: true,
+      disallowAmbiguousJSXLike: false,
+      // ... other options
+    }]
+  ]
+}
+```
+
+### TypeScript JSX Files (.tsx)
+
+TypeScript files with JSX receive TypeScript transformation plus JSX syntax support:
+
+```javascript
+// Configuration applied for .tsx files
+{
+  plugins: [
+    ['@babel/plugin-transform-typescript', { 
+      isTSX: true,
+      allowNamespaces: true,
+      // ... other options
+    }],
+    '@babel/plugin-syntax-jsx'
+  ]
+}
+```
+
+### ES Module TypeScript (.mts)
+
+TypeScript ES module files with strict module type checking:
+
+```javascript
+// Configuration applied for .mts files
+{
+  sourceType: "module",
+  plugins: [
+    ['@babel/plugin-transform-typescript', { 
+      disallowAmbiguousJSXLike: true,
+      // ... other options
+    }]
+  ]
+}
+```
+
+### CommonJS TypeScript (.cts)
+
+TypeScript CommonJS files with automatic CommonJS transformation:
+
+```javascript
+// Configuration applied for .cts files
+{
+  sourceType: "unambiguous",
+  plugins: [
+    ['@babel/plugin-transform-modules-commonjs', { 
+      allowTopLevelThis: true 
+    }],
+    ['@babel/plugin-transform-typescript', { 
+      disallowAmbiguousJSXLike: true,
+      // ... other options
+    }]
+  ]
+}
+```
+
+## Version Compatibility
+
+### Babel 7 Compatibility
+
+Babel 7 supports additional legacy options:
+
+- `allowDeclareFields`: Controls TypeScript declare field support
+- `allExtensions`: Forces handling of all file extensions
+- `isTSX`: Forces JSX parsing for all files
+
+### Babel 8 Compatibility
+
+Babel 8 removes deprecated options and enforces stricter validation:
+
+- Removes `allowDeclareFields`, `allExtensions`, and `isTSX` options
+- Stricter option validation with helpful error messages
+- Enhanced Node.js version requirements (>=20.19.0 || >=22.12.0)
+
+## Plugin Dependencies
+
+The preset automatically configures these Babel plugins:
+
+- **@babel/plugin-transform-typescript**: Core TypeScript syntax transformation
+- **@babel/plugin-syntax-jsx**: JSX syntax parsing support
+- **@babel/plugin-transform-modules-commonjs**: CommonJS module transformation (for .cts files)
+
+## Common Configuration Examples
+
+### React TypeScript Project
+
+```javascript
+// babel.config.js
+module.exports = {
+  presets: [
+    ['@babel/preset-typescript', {
+      jsxPragma: 'React',
+      jsxPragmaFrag: 'React.Fragment'
+    }],
+    '@babel/preset-react'
+  ]
+};
+```
+
+### Node.js TypeScript Project
+
+```javascript
+// babel.config.js
+module.exports = {
+  presets: [
+    ['@babel/preset-typescript', {
+      allowNamespaces: true,
+      optimizeConstEnums: true
+    }],
+    ['@babel/preset-env', {
+      targets: { node: 'current' }
+    }]
+  ]
+};
+```
+
+### Strict TypeScript Configuration
+
+```javascript
+// babel.config.js
+module.exports = {
+  presets: [
+    ['@babel/preset-typescript', {
+      onlyRemoveTypeImports: true,
+      disallowAmbiguousJSXLike: true,
+      ignoreExtensions: true
+    }]
+  ]
+};
+```
+
+### Import Extension Rewriting
+
+```javascript
+// babel.config.js
+module.exports = {
+  presets: [
+    ['@babel/preset-typescript', {
+      rewriteImportExtensions: true
+    }]
+  ]
+};
+```
+
+This configuration transforms:
+
+```typescript
+// Input TypeScript
+import { helper } from './utils.ts';
+import Component from './Component.tsx';
+
+// Output JavaScript
+import { helper } from './utils.js';
+import Component from './Component.jsx';
+```

+# Database Management
+
+Core database connection and lifecycle management functionality for creating, configuring, and controlling SQLite database connections.
+
+## Capabilities
+
+### Database Constructor
+
+Creates a new database connection with comprehensive configuration options.
+
+```javascript { .api }
+/**
+ * Creates a new database connection
+ * @param {string|Buffer} filename - Database file path, ":memory:" for in-memory, or Buffer for serialized database  
+ * @param {Object} [options] - Database configuration options
+ * @returns {Database} Database instance
+ */
+function Database(filename, options);
+
+interface DatabaseOptions {
+  readonly?: boolean;        // Open in readonly mode (default: false)
+  fileMustExist?: boolean;   // Throw error if file doesn't exist (default: false)
+  timeout?: number;          // Timeout in ms for locked database (default: 5000)
+  verbose?: Function;        // Function called with every SQL execution
+  nativeBinding?: string | Object; // Path to native binding or binding object
+}
+```
+
+**Usage Examples:**
+
+```javascript
+const Database = require('better-sqlite3');
+
+// Create/open a file database
+const db = new Database('myapp.db');
+
+// Create in-memory database
+const memDb = new Database(':memory:');
+
+// Create temporary database (deleted when closed)
+const tempDb = new Database('');
+
+// Open readonly database
+const readOnlyDb = new Database('data.db', { readonly: true });
+
+// Database with timeout and verbose logging
+const verboseDb = new Database('app.db', {
+  timeout: 10000,
+  verbose: console.log
+});
+
+// Database that must exist (throws if file missing)
+const existingDb = new Database('existing.db', { fileMustExist: true });
+
+// Create from serialized buffer
+const serializedBuffer = fs.readFileSync('backup.db');
+const restoredDb = new Database(serializedBuffer);
+```
+
+### Direct SQL Execution
+
+Execute SQL statements directly without prepared statements.
+
+```javascript { .api }
+/**
+ * Execute SQL string directly (no prepared statement)
+ * @param {string} sql - SQL query string (can contain multiple statements)
+ * @returns {Database} Database instance for chaining
+ */
+exec(sql);
+```
+
+**Usage Examples:**
+
+```javascript
+// Create tables and initial data
+db.exec(`
+  CREATE TABLE IF NOT EXISTS users (
+    id INTEGER PRIMARY KEY,
+    name TEXT NOT NULL,
+    email TEXT UNIQUE
+  );
+  
+  CREATE INDEX IF NOT EXISTS idx_users_email ON users(email);
+  
+  INSERT OR IGNORE INTO users (name, email) VALUES 
+    ('Admin', 'admin@example.com'),
+    ('Guest', 'guest@example.com');
+`);
+
+// Drop and recreate table
+db.exec('DROP TABLE IF EXISTS temp_data; CREATE TABLE temp_data (value TEXT);');
+```
+
+### Database Connection Management
+
+Close database connections and manage connection lifecycle.
+
+```javascript { .api }
+/**
+ * Close database connection
+ * @returns {Database} Database instance for chaining
+ */
+close();
+```
+
+**Usage Examples:**
+
+```javascript
+// Proper database cleanup
+try {
+  const db = new Database('myapp.db');
+  
+  // Use database...
+  
+} finally {
+  // Always close the database
+  db.close();
+}
+
+// Check if database is still open
+console.log(db.open); // false after closing
+```
+
+### Extension Loading
+
+Load SQLite extensions to add functionality.
+
+```javascript { .api }
+/**
+ * Load SQLite extension
+ * @param {string} path - Path to extension file (.dll, .so, .dylib)
+ * @param {string} [entrypoint] - Entry point function name (optional)
+ * @returns {Database} Database instance for chaining
+ */
+loadExtension(path, entrypoint);
+```
+
+**Usage Examples:**
+
+```javascript
+// Load extension with automatic entry point
+db.loadExtension('./extensions/json1.so');
+
+// Load extension with specific entry point
+db.loadExtension('./extensions/fts5.so', 'sqlite3_fts5_init');
+
+// Load multiple extensions
+db.loadExtension('./extensions/rtree.so')
+  .loadExtension('./extensions/soundex.so');
+```
+
+### Database Configuration
+
+Configure database-wide settings for integer handling and safety modes.
+
+```javascript { .api }
+/**
+ * Set default safe integer handling for new statements
+ * @param {boolean} enabled - Enable safe integers by default
+ * @returns {Database} Database instance for chaining
+ */
+defaultSafeIntegers(enabled);
+
+/**
+ * Enable/disable unsafe mode (disables certain safety checks)
+ * @param {boolean} enabled - Enable unsafe mode
+ * @returns {Database} Database instance for chaining
+ */
+unsafeMode(enabled);
+```
+
+**Usage Examples:**
+
+```javascript
+// Enable safe integers for large numbers
+db.defaultSafeIntegers(true);
+
+// All new prepared statements will use safe integers
+const stmt = db.prepare('SELECT very_large_number FROM table');
+const result = stmt.get(); // Returns BigInt for large integers
+
+// Enable unsafe mode for maximum performance (use with caution)
+db.unsafeMode(true);
+```
+
+### Database Properties
+
+Read-only properties providing database connection information.
+
+```javascript { .api }
+interface DatabaseProperties {
+  readonly name: string;          // Database filename or ":memory:" 
+  readonly open: boolean;         // Whether connection is open
+  readonly inTransaction: boolean; // Whether currently in transaction
+  readonly readonly: boolean;     // Whether database is readonly
+  readonly memory: boolean;       // Whether database is in-memory
+}
+```
+
+**Usage Examples:**
+
+```javascript
+const db = new Database('myapp.db', { readonly: true });
+
+console.log(db.name);          // "myapp.db"
+console.log(db.open);          // true
+console.log(db.readonly);      // true
+console.log(db.memory);        // false
+console.log(db.inTransaction); // false
+
+// Properties update automatically
+const transaction = db.transaction(() => {
+  console.log(db.inTransaction); // true during transaction
+});
+
+transaction();
+console.log(db.inTransaction); // false after transaction
+
+db.close();
+console.log(db.open); // false
+```
+
+## Error Handling
+
+```javascript { .api }
+class SqliteError extends Error {
+  constructor(message, code);
+  readonly name: string;    // Always "SqliteError"
+  readonly code: string;    // SQLite error code (e.g., "SQLITE_CONSTRAINT")
+  readonly message: string; // Descriptive error message
+}
+```
+
+**Common Error Scenarios:**
+
+```javascript
+try {
+  const db = new Database('nonexistent.db', { fileMustExist: true });
+} catch (error) {
+  if (error instanceof Database.SqliteError) {
+    console.log(error.code);    // "SQLITE_CANTOPEN"
+    console.log(error.message); // "Cannot open database..."
+  }
+}
+
+try {
+  db.exec('INVALID SQL SYNTAX');
+} catch (error) {
+  console.log(error.code);    // "SQLITE_ERROR"
+  console.log(error.message); // "near \"INVALID\": syntax error"
+}
+```

+# Database Utilities
+
+Utility functions for database introspection, backup, serialization, and configuration management.
+
+## Capabilities
+
+### PRAGMA Commands
+
+Execute PRAGMA commands for database configuration and introspection.
+
+```javascript { .api }
+/**
+ * Execute PRAGMA commands for database configuration and introspection
+ * @param {string} source - PRAGMA command string (without "PRAGMA" prefix)
+ * @param {Object} [options] - Execution options
+ * @returns {Array|any} Results array or single value if simple mode
+ */
+pragma(source, options);
+
+interface PragmaOptions {
+  simple?: boolean; // Return single value instead of array (default: false)
+}
+```
+
+**Usage Examples:**
+
+```javascript
+// Get database information
+const userVersion = db.pragma('user_version', { simple: true });
+console.log(userVersion); // Returns number directly
+
+// Get table information
+const tableInfo = db.pragma('table_info(users)');
+console.log(tableInfo);
+// Returns array of column descriptors:
+// [
+//   { cid: 0, name: 'id', type: 'INTEGER', notnull: 0, dflt_value: null, pk: 1 },
+//   { cid: 1, name: 'name', type: 'TEXT', notnull: 1, dflt_value: null, pk: 0 },
+//   ...
+// ]
+
+// Get foreign key information
+const foreignKeys = db.pragma('foreign_key_list(orders)');
+foreignKeys.forEach(fk => {
+  console.log(`${fk.from} references ${fk.table}.${fk.to}`);
+});
+
+// Database configuration
+db.pragma('journal_mode = WAL'); // Enable WAL mode
+db.pragma('synchronous = NORMAL'); // Set synchronous mode
+db.pragma('cache_size = 10000'); // Set cache size
+
+// Get current settings
+const journalMode = db.pragma('journal_mode', { simple: true });
+const pageSize = db.pragma('page_size', { simple: true });
+const cacheSize = db.pragma('cache_size', { simple: true });
+
+console.log(`Journal mode: ${journalMode}, Page size: ${pageSize}, Cache size: ${cacheSize}`);
+```
+
+### Database Backup
+
+Create backups of the database to files with progress monitoring.
+
+```javascript { .api }
+/**
+ * Backup database to file (async operation)
+ * @param {string} filename - Destination file path
+ * @param {Object} [options] - Backup options
+ * @returns {Promise<BackupProgress>} Promise resolving to backup completion info
+ */
+backup(filename, options);
+
+interface BackupOptions {
+  attached?: string;   // Database name to backup (default: "main")
+  progress?: Function; // Progress callback function
+}
+
+interface BackupProgress {
+  totalPages: number;     // Total pages in database
+  remainingPages: number; // Pages remaining to backup (0 when complete)
+}
+```
+
+**Usage Examples:**
+
+```javascript
+// Simple backup
+await db.backup('backup.db');
+console.log('Backup completed');
+
+// Backup with progress monitoring
+await db.backup('backup-with-progress.db', {
+  progress(info) {
+    const percent = ((info.totalPages - info.remainingPages) / info.totalPages * 100).toFixed(1);
+    console.log(`Backup progress: ${percent}% (${info.remainingPages} pages remaining)`);
+    
+    // Return custom page transfer rate (optional)
+    // return 100; // Transfer 100 pages at a time
+  }
+});
+
+// Backup attached database
+db.exec("ATTACH DATABASE 'other.db' AS other");
+await db.backup('other-backup.db', { attached: 'other' });
+
+// Backup with error handling
+try {
+  await db.backup('/invalid/path/backup.db');
+} catch (error) {
+  console.error('Backup failed:', error.message);
+}
+
+// Throttled backup for large databases
+await db.backup('large-backup.db', {
+  progress(info) {
+    if (info.remainingPages > 0) {
+      // Transfer fewer pages at a time to avoid blocking
+      return 10;
+    }
+  }
+});
+```
+
+### Database Serialization
+
+Serialize database to Buffer for embedding or transmission.
+
+```javascript { .api }
+/**
+ * Serialize database to Buffer
+ * @param {Object} [options] - Serialization options
+ * @returns {Buffer} Buffer containing complete serialized database
+ */
+serialize(options);
+
+interface SerializeOptions {
+  attached?: string; // Database name to serialize (default: "main")
+}
+```
+
+**Usage Examples:**
+
+```javascript
+// Serialize entire database to buffer
+const serialized = db.serialize();
+console.log(`Database serialized to ${serialized.length} bytes`);
+
+// Save serialized database to file
+const fs = require('fs');
+fs.writeFileSync('serialized-db.buf', serialized);
+
+// Restore database from serialized buffer
+const restoredDb = new Database(serialized);
+
+// Serialize attached database
+db.exec("ATTACH DATABASE 'temp.db' AS temp");
+const tempSerialized = db.serialize({ attached: 'temp' });
+
+// Use serialization for database cloning
+function cloneDatabase(sourceDb) {
+  const serialized = sourceDb.serialize();
+  return new Database(serialized);
+}
+
+const clonedDb = cloneDatabase(db);
+
+// Serialization with compression (using external library)
+const zlib = require('zlib');
+const serialized = db.serialize();
+const compressed = zlib.gzipSync(serialized);
+console.log(`Compressed from ${serialized.length} to ${compressed.length} bytes`);
+
+// Restore from compressed
+const decompressed = zlib.gunzipSync(compressed);
+const restoredFromCompressed = new Database(decompressed);
+```
+
+### Database Analysis and Introspection
+
+Use PRAGMA commands for comprehensive database analysis.
+
+```javascript { .api }
+// Common introspection patterns using pragma()
+```
+
+**Schema Information:**
+
+```javascript
+// Get all table names
+const tables = db.pragma('table_list');
+const tableNames = tables.map(table => table.name);
+console.log('Tables:', tableNames);
+
+// Get detailed table information
+function getTableSchema(tableName) {
+  const columns = db.pragma(`table_info(${tableName})`);
+  const indexes = db.pragma(`index_list(${tableName})`);
+  const foreignKeys = db.pragma(`foreign_key_list(${tableName})`);
+  
+  return {
+    columns: columns.map(col => ({
+      name: col.name,
+      type: col.type,
+      nullable: !col.notnull,
+      defaultValue: col.dflt_value,
+      primaryKey: !!col.pk
+    })),
+    indexes: indexes.map(idx => ({
+      name: idx.name,
+      unique: !!idx.unique,
+      partial: !!idx.partial
+    })),
+    foreignKeys: foreignKeys.map(fk => ({
+      column: fk.from,
+      referencesTable: fk.table,
+      referencesColumn: fk.to,
+      onUpdate: fk.on_update,
+      onDelete: fk.on_delete
+    }))
+  };
+}
+
+const userSchema = getTableSchema('users');
+console.log(userSchema);
+```
+
+**Database Statistics:**
+
+```javascript
+// Get database size and page information
+const pageCount = db.pragma('page_count', { simple: true });
+const pageSize = db.pragma('page_size', { simple: true });
+const freePages = db.pragma('freelist_count', { simple: true });
+
+const totalSize = pageCount * pageSize;
+const freeSize = freePages * pageSize;
+const usedSize = totalSize - freeSize;
+
+console.log(`Database size: ${totalSize} bytes`);
+console.log(`Used: ${usedSize} bytes (${(usedSize/totalSize*100).toFixed(1)}%)`);
+console.log(`Free: ${freeSize} bytes (${(freeSize/totalSize*100).toFixed(1)}%)`);
+
+// Get compilation options
+const compileOptions = db.pragma('compile_options');
+console.log('SQLite compile options:', compileOptions);
+
+// Check integrity
+const integrityCheck = db.pragma('integrity_check');
+if (integrityCheck.length === 1 && integrityCheck[0] === 'ok') {
+  console.log('Database integrity OK');
+} else {
+  console.warn('Database integrity issues:', integrityCheck);
+}
+```
+
+**Performance Analysis:**
+
+```javascript
+// Analyze query performance
+function analyzeQuery(sql) {
+  const queryPlan = db.pragma(`query_plan(${sql})`);
+  console.log('Query execution plan:');
+  queryPlan.forEach(step => {
+    console.log(`${step.id}: ${step.detail}`);
+  });
+}
+
+analyzeQuery('SELECT * FROM users WHERE email = "test@example.com"');
+
+// Get database statistics
+const stats = db.pragma('stats');
+stats.forEach(stat => {
+  console.log(`${stat.table}: ${stat.index} (${stat.cells} cells)`);
+});
+```
+
+### Database Optimization
+
+Utility functions for database maintenance and optimization.
+
+**Vacuum and Analyze:**
+
+```javascript
+// Optimize database storage
+function optimizeDatabase() {
+  console.log('Starting database optimization...');
+  
+  // Analyze all tables for query planner statistics
+  db.exec('ANALYZE');
+  
+  // Rebuild database to reclaim space
+  db.exec('VACUUM');
+  
+  console.log('Database optimization completed');
+}
+
+// Incremental vacuum (for WAL mode)
+function incrementalVacuum(pages = 1000) {
+  db.pragma(`incremental_vacuum(${pages})`);
+}
+
+// Auto-vacuum configuration
+db.pragma('auto_vacuum = INCREMENTAL');
+```
+
+**Checkpoint Management (WAL Mode):**
+
+```javascript
+// Checkpoint WAL file
+function checkpoint(mode = 'PASSIVE') {
+  const result = db.pragma(`wal_checkpoint(${mode})`, { simple: false });
+  return {
+    busy: result[0],
+    log: result[1],
+    checkpointed: result[2]
+  };
+}
+
+// Different checkpoint modes
+const passiveResult = checkpoint('PASSIVE'); // Non-blocking
+const fullResult = checkpoint('FULL');       // Block until complete
+const restartResult = checkpoint('RESTART'); // Reset WAL file
+
+console.log('Checkpoint results:', fullResult);
+```
+
+### Configuration Management
+
+Manage database-wide configuration settings.
+
+```javascript
+// Performance tuning
+function configureForPerformance() {
+  db.pragma('journal_mode = WAL');      // Enable WAL mode for better concurrency
+  db.pragma('synchronous = NORMAL');    // Balance safety and performance
+  db.pragma('cache_size = 10000');      // Increase cache size
+  db.pragma('temp_store = MEMORY');     // Use memory for temporary tables
+  db.pragma('mmap_size = 134217728');   // Enable memory mapping (128MB)
+}
+
+// Safety-first configuration
+function configureForSafety() {
+  db.pragma('journal_mode = DELETE');   // Traditional rollback journal
+  db.pragma('synchronous = FULL');      // Maximum durability
+  db.pragma('foreign_keys = ON');       // Enforce foreign key constraints
+}
+
+// Get current configuration
+function getCurrentConfig() {
+  return {
+    journalMode: db.pragma('journal_mode', { simple: true }),
+    synchronous: db.pragma('synchronous', { simple: true }),
+    cacheSize: db.pragma('cache_size', { simple: true }),
+    foreignKeys: db.pragma('foreign_keys', { simple: true }),
+    autoVacuum: db.pragma('auto_vacuum', { simple: true }),
+    mmapSize: db.pragma('mmap_size', { simple: true })
+  };
+}
+
+console.log('Current configuration:', getCurrentConfig());

+# better-sqlite3
+
+better-sqlite3 is the fastest and simplest library for SQLite3 in Node.js, providing a synchronous API for high-performance database operations. Unlike the standard node-sqlite3 module which uses callbacks, better-sqlite3 offers direct return values and eliminates callback complexity while maintaining full SQLite feature support.
+
+## Package Information
+
+- **Package Name**: better-sqlite3
+- **Package Type**: npm
+- **Language**: JavaScript (with TypeScript definitions)
+- **Installation**: `npm install better-sqlite3`
+
+## Core Imports
+
+```javascript
+const Database = require('better-sqlite3');
+```
+
+For TypeScript:
+
+```typescript
+import Database from 'better-sqlite3';
+// Or for named imports
+import Database, { SqliteError } from 'better-sqlite3';
+```
+
+## Basic Usage
+
+```javascript
+const Database = require('better-sqlite3');
+
+// Create/open database
+const db = new Database('mydb.sqlite');
+
+// Create table
+db.exec('CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT, email TEXT)');
+
+// Prepare and execute statements
+const insert = db.prepare('INSERT INTO users (name, email) VALUES (?, ?)');
+const insertResult = insert.run('John Doe', 'john@example.com');
+console.log(insertResult.lastInsertRowid); // 1
+
+// Query data
+const getUser = db.prepare('SELECT * FROM users WHERE id = ?');
+const user = getUser.get(1);
+console.log(user); // { id: 1, name: 'John Doe', email: 'john@example.com' }
+
+// Close database
+db.close();
+```
+
+## Architecture
+
+better-sqlite3 is built around several key components:

+# Statement Execution
+
+Prepared statement functionality for efficient SQL query execution with parameter binding and result handling.
+
+## Capabilities
+
+### Statement Preparation
+
+Create prepared statements from SQL strings for efficient repeated execution.
+
+```javascript { .api }
+/**
+ * Creates a prepared statement from SQL string
+ * @param {string} sql - SQL query string with optional parameter placeholders
+ * @returns {Statement} Prepared statement object
+ */
+prepare(sql);
+```
+
+**Usage Examples:**
+
+```javascript
+// Prepare INSERT statement
+const insertUser = db.prepare('INSERT INTO users (name, email) VALUES (?, ?)');
+
+// Prepare SELECT statement with named parameters
+const getUserByEmail = db.prepare('SELECT * FROM users WHERE email = @email');
+
+// Prepare UPDATE statement with mixed parameters
+const updateUser = db.prepare('UPDATE users SET name = ? WHERE id = $id');
+
+// Prepare complex query
+const getOrdersWithDetails = db.prepare(`
+  SELECT o.id, o.total, u.name as customer_name, 
+         COUNT(oi.id) as item_count
+  FROM orders o
+  JOIN users u ON o.user_id = u.id
+  LEFT JOIN order_items oi ON o.id = oi.order_id
+  WHERE o.created_at > ?
+  GROUP BY o.id
+  ORDER BY o.created_at DESC
+`);
+```
+
+### Statement Execution Methods
+
+Execute prepared statements and retrieve results in different formats.
+
+```javascript { .api }
+/**
+ * Execute statement for data modification, return info about changes
+ * @param {...any} params - Parameters to bind to statement
+ * @returns {RunResult} Object with changes and lastInsertRowid
+ */
+run(...params);
+
+/**
+ * Execute statement and return first row
+ * @param {...any} params - Parameters to bind to statement  
+ * @returns {Object|undefined} First row object or undefined if no results
+ */
+get(...params);
+
+/**
+ * Execute statement and return all rows
+ * @param {...any} params - Parameters to bind to statement
+ * @returns {Object[]} Array of row objects
+ */
+all(...params);
+
+/**
+ * Execute statement and return iterator for memory-efficient processing
+ * @param {...any} params - Parameters to bind to statement
+ * @returns {Iterator<Object>} Iterator yielding row objects
+ */
+iterate(...params);
+
+interface RunResult {
+  changes: number;        // Number of rows changed by the operation
+  lastInsertRowid: number; // Row ID of last inserted row (0 if none)
+}
+```
+
+**Usage Examples:**
+
+```javascript
+// Using run() for data modification
+const insertUser = db.prepare('INSERT INTO users (name, email) VALUES (?, ?)');
+const result = insertUser.run('Alice Smith', 'alice@example.com');
+console.log(result.changes);        // 1
+console.log(result.lastInsertRowid); // 1 (the new user's ID)
+
+// Using get() for single row retrieval
+const getUser = db.prepare('SELECT * FROM users WHERE id = ?');
+const user = getUser.get(1);
+console.log(user); // { id: 1, name: 'Alice Smith', email: 'alice@example.com' }
+
+// Using all() for multiple rows
+const getAllUsers = db.prepare('SELECT * FROM users ORDER BY name');
+const users = getAllUsers.all();
+console.log(users.length); // Number of users
+users.forEach(user => console.log(user.name));
+
+// Using iterate() for memory-efficient processing of large result sets
+const getActiveOrders = db.prepare('SELECT * FROM orders WHERE status = ?');
+for (const order of getActiveOrders.iterate('active')) {
+  console.log(`Order ${order.id}: $${order.total}`);
+  // Process one order at a time without loading all into memory
+}
+```
+
+### Parameter Binding
+
+Bind parameters to prepared statements for secure and efficient execution.
+
+```javascript { .api }
+/**
+ * Permanently bind parameters to statement
+ * @param {...any} params - Parameters to bind (positional or named)
+ * @returns {Statement} Statement instance for chaining
+ */
+bind(...params);
+```
+
+**Parameter Binding Styles:**
+
+```javascript
+// Positional parameters with ?
+const stmt1 = db.prepare('SELECT * FROM users WHERE age > ? AND city = ?');
+stmt1.run(25, 'New York'); // Temporary binding
+stmt1.bind(25, 'New York'); // Permanent binding
+
+// Named parameters with @name, :name, or $name
+const stmt2 = db.prepare('SELECT * FROM users WHERE age > @minAge AND city = @city');
+stmt2.run({ minAge: 25, city: 'New York' });
+
+// Object binding for named parameters
+const stmt3 = db.prepare('INSERT INTO users (name, email, age) VALUES (@name, @email, @age)');
+stmt3.run({
+  name: 'Bob Wilson',
+  email: 'bob@example.com', 
+  age: 30
+});
+
+// Array binding for positional parameters
+const stmt4 = db.prepare('INSERT INTO users (name, email, age) VALUES (?, ?, ?)');
+stmt4.run(['Charlie Brown', 'charlie@example.com', 28]);
+
+// Permanent binding prevents further parameter passing
+const boundStmt = db.prepare('SELECT * FROM users WHERE status = ?');
+boundStmt.bind('active');
+// boundStmt.run('inactive'); // Would throw TypeError
+```
+
+### Statement Configuration
+
+Configure statement behavior for result formatting and data handling.
+
+```javascript { .api }
+/**
+ * Enable/disable column plucking (return only first column value)
+ * @param {boolean} enabled - Enable plucking mode
+ * @returns {Statement} Statement instance for chaining
+ */
+pluck(enabled);
+
+/**
+ * Enable/disable row expansion (return nested objects by table)
+ * @param {boolean} enabled - Enable expansion mode
+ * @returns {Statement} Statement instance for chaining
+ */
+expand(enabled);
+
+/**
+ * Enable/disable raw mode (return arrays instead of objects)
+ * @param {boolean} enabled - Enable raw mode
+ * @returns {Statement} Statement instance for chaining
+ */
+raw(enabled);
+
+/**
+ * Enable/disable safe integer mode for this statement
+ * @param {boolean} enabled - Enable safe integers (return BigInt for large numbers)
+ * @returns {Statement} Statement instance for chaining
+ */
+safeIntegers(enabled);
+```
+
+**Usage Examples:**
+
+```javascript
+// Pluck mode - return only first column value
+const getName = db.prepare('SELECT name FROM users WHERE id = ?').pluck();
+const name = getName.get(1); // Returns "Alice Smith" instead of { name: "Alice Smith" }
+
+// Raw mode - return arrays instead of objects
+const getUserRaw = db.prepare('SELECT id, name, email FROM users WHERE id = ?').raw();
+const userData = getUserRaw.get(1); // Returns [1, "Alice Smith", "alice@example.com"]
+
+// Expand mode - nested objects by table
+const getOrderWithUser = db.prepare(`
+  SELECT o.id, o.total, u.name, u.email 
+  FROM orders o 
+  JOIN users u ON o.user_id = u.id 
+  WHERE o.id = ?
+`).expand();
+const result = getOrderWithUser.get(1);
+// Returns: { orders: { id: 1, total: 99.99 }, users: { name: "Alice", email: "alice@example.com" } }
+
+// Safe integers for handling large numbers
+const getBigNumber = db.prepare('SELECT big_integer_column FROM table WHERE id = ?').safeIntegers();
+const bigNum = getBigNumber.get(1); // Returns BigInt instead of potentially unsafe number
+
+// Chain configuration methods
+const configuredStmt = db.prepare('SELECT COUNT(*) as count FROM users')
+  .pluck()        // Only return the count value
+  .safeIntegers(true); // Use BigInt for large counts
+const userCount = configuredStmt.get(); // Returns BigInt directly
+```
+
+### Statement Metadata
+
+Retrieve metadata information about prepared statements.
+
+```javascript { .api }
+/**
+ * Get column information for SELECT statements
+ * @returns {ColumnDescriptor[]} Array of column descriptors
+ */
+columns();
+
+interface ColumnDescriptor {
+  name: string;           // Column name in result set
+  column: string | null;  // Original column name (null for expressions)
+  table: string | null;   // Source table name (null for expressions)
+  database: string | null; // Database name (typically "main")
+  type: string | null;    // Declared column type (null for expressions)
+}
+```
+
+**Usage Examples:**
+
+```javascript
+// Get column metadata
+const stmt = db.prepare('SELECT u.id, u.name, COUNT(*) as order_count FROM users u LEFT JOIN orders o ON u.id = o.user_id GROUP BY u.id');
+const columns = stmt.columns();
+
+columns.forEach(col => {
+  console.log(`Column: ${col.name}`);
+  console.log(`  Original: ${col.column}`);
+  console.log(`  Table: ${col.table}`);
+  console.log(`  Type: ${col.type}`);
+});
+
+// Output:
+// Column: id
+//   Original: id
+//   Table: users
+//   Type: INTEGER
+// Column: name  
+//   Original: name
+//   Table: users
+//   Type: TEXT
+// Column: order_count
+//   Original: null
+//   Table: null
+//   Type: null
+```
+
+### Statement Properties
+
+Read-only properties providing statement information.
+
+```javascript { .api }
+interface StatementProperties {
+  readonly reader: boolean;       // Whether statement returns data (SELECT vs INSERT/UPDATE/etc)
+  readonly busy: boolean;         // Whether statement is currently executing
+  readonly database: Database;    // Associated database instance
+}
+```
+
+**Usage Examples:**
+
+```javascript
+const selectStmt = db.prepare('SELECT * FROM users');
+const insertStmt = db.prepare('INSERT INTO users (name) VALUES (?)');
+
+console.log(selectStmt.reader); // true (SELECT statement)
+console.log(insertStmt.reader); // false (INSERT statement)
+
+// Can't use get/all/iterate on non-reader statements
+try {
+  insertStmt.get(); // Throws TypeError
+} catch (error) {
+  console.log(error.message); // "This statement does not return data"
+}
+
+// Can't use columns() on non-reader statements  
+try {
+  insertStmt.columns(); // Throws TypeError
+} catch (error) {
+  console.log(error.message); // "This statement does not return data"
+}
+
+console.log(selectStmt.database === db); // true
+console.log(selectStmt.busy); // false (when not executing)
+```
+
+## Data Type Conversions
+
+better-sqlite3 automatically converts between JavaScript and SQLite data types:
+
+**JavaScript to SQLite:**
+- `null`, `undefined` → NULL
+- `string` → TEXT  
+- `number` → INTEGER or REAL
+- `bigint` → INTEGER (when safe integers enabled)
+- `boolean` → INTEGER (0 or 1)
+- `Buffer` → BLOB
+- `Date` → TEXT (ISO string) or INTEGER (timestamp)
+
+**SQLite to JavaScript:**
+- NULL → `null`
+- INTEGER → `number` or `bigint` (when safe integers enabled)
+- REAL → `number`
+- TEXT → `string`
+- BLOB → `Buffer`
+
+**Usage Examples:**
+
+```javascript
+// Inserting different data types
+const insertData = db.prepare('INSERT INTO mixed_data (text_col, int_col, real_col, blob_col, bool_col) VALUES (?, ?, ?, ?, ?)');
+insertData.run(
+  'Hello World',              // TEXT
+  42,                         // INTEGER  
+  3.14159,                    // REAL
+  Buffer.from('binary data'), // BLOB
+  true                        // INTEGER (1)
+);
+
+// Date handling
+const insertDate = db.prepare('INSERT INTO events (name, created_at) VALUES (?, ?)');
+insertDate.run('Event Name', new Date()); // Date becomes TEXT ISO string
+
+// Large integer handling with safe integers
+db.defaultSafeIntegers(true);
+const insertBigInt = db.prepare('INSERT INTO big_numbers (value) VALUES (?)');
+insertBigInt.run(9007199254740992n); // BigInt preserved as INTEGER
+
+const getBigInt = db.prepare('SELECT value FROM big_numbers WHERE id = ?');
+const result = getBigInt.get(1);
+console.log(typeof result.value); // "bigint"
+```

+# Transaction Management
+
+Transaction system providing ACID compliance with support for nested transactions using savepoints and multiple transaction types.
+
+## Capabilities
+
+### Transaction Creation
+
+Create transaction wrapper functions that automatically handle BEGIN/COMMIT/ROLLBACK operations.
+
+```javascript { .api }
+/**
+ * Creates a transaction function wrapper
+ * @param {Function} fn - Function to execute within transaction
+ * @returns {TransactionFunction} Transaction function with transaction type variants
+ */
+transaction(fn);
+
+interface TransactionFunction {
+  (...args): any;              // Default transaction using BEGIN
+  deferred(...args): any;      // Deferred transaction using BEGIN DEFERRED  
+  immediate(...args): any;     // Immediate transaction using BEGIN IMMEDIATE
+  exclusive(...args): any;     // Exclusive transaction using BEGIN EXCLUSIVE
+  readonly database: Database; // Associated database instance
+}
+```
+
+**Usage Examples:**
+
+```javascript
+// Create transaction function
+const insertMany = db.transaction((users) => {
+  const insert = db.prepare('INSERT INTO users (name, email) VALUES (@name, @email)');
+  for (const user of users) {
+    insert.run(user);
+  }
+});
+
+// Execute transaction
+insertMany([
+  { name: 'Alice', email: 'alice@example.com' },
+  { name: 'Bob', email: 'bob@example.com' },
+  { name: 'Charlie', email: 'charlie@example.com' }
+]);
+
+// All users inserted atomically, or none if any fails
+```
+
+### Transaction Types
+
+Different transaction types provide various levels of locking and concurrency control.
+
+```javascript { .api }
+// Transaction type variants
+transactionFunction();              // BEGIN (same as deferred)
+transactionFunction.deferred();     // BEGIN DEFERRED (default SQLite behavior)
+transactionFunction.immediate();    // BEGIN IMMEDIATE (acquire reserved lock immediately)
+transactionFunction.exclusive();    // BEGIN EXCLUSIVE (acquire exclusive lock immediately)
+```
+
+**Transaction Type Behaviors:**
+
+```javascript
+const updateInventory = db.transaction((items) => {
+  const update = db.prepare('UPDATE inventory SET quantity = quantity - ? WHERE item_id = ?');
+  for (const item of items) {
+    update.run(item.quantity, item.id);
+  }
+});
+
+// Deferred transaction - acquire locks as needed (default)
+updateInventory.deferred(items);
+
+// Immediate transaction - acquire reserved lock immediately 
+// (prevents other writers from starting)
+updateInventory.immediate(items);
+
+// Exclusive transaction - acquire exclusive lock immediately
+// (prevents all other connections from reading or writing)
+updateInventory.exclusive(items);
+```
+
+### Nested Transactions
+
+Transactions can be nested using SQLite savepoints for complex error handling scenarios.
+
+```javascript { .api }
+// Nested transactions automatically use savepoints
+// Inner transaction failures roll back to savepoint, not beginning
+```
+
+**Usage Examples:**
+
+```javascript
+const insertUser = db.prepare('INSERT INTO users (name, email) VALUES (?, ?)');
+const insertProfile = db.prepare('INSERT INTO profiles (user_id, bio) VALUES (?, ?)');
+const insertPreferences = db.prepare('INSERT INTO preferences (user_id, theme) VALUES (?, ?)');
+
+// Outer transaction
+const createUserWithProfile = db.transaction((userData) => {
+  // Insert user
+  const userResult = insertUser.run(userData.name, userData.email);
+  const userId = userResult.lastInsertRowid;
+  
+  // Inner transaction for profile creation
+  const createProfile = db.transaction((profileData) => {
+    insertProfile.run(userId, profileData.bio);
+    
+    if (profileData.preferences) {
+      // Nested inner transaction for preferences
+      const setPreferences = db.transaction((prefs) => {
+        insertPreferences.run(userId, prefs.theme);
+        if (prefs.theme === 'invalid') {
+          throw new Error('Invalid theme'); // This will rollback only preferences
+        }
+      });
+      
+      setPreferences(profileData.preferences);
+    }
+  });
+  
+  try {
+    createProfile(userData.profile);
+  } catch (error) {
+    console.log('Profile creation failed, but user was created');
+    // User insert is preserved, only profile operations rolled back
+  }
+});
+
+// Execute the nested transaction
+createUserWithProfile({
+  name: 'John Doe',
+  email: 'john@example.com',
+  profile: {
+    bio: 'Software developer',
+    preferences: { theme: 'dark' }
+  }
+});
+```
+
+### Transaction Error Handling
+
+Transactions automatically handle errors with proper rollback behavior.
+
+```javascript { .api }
+// Automatic rollback on any thrown error
+// Error propagates normally after rollback
+// Nested transactions use savepoints for partial rollback
+```
+
+**Usage Examples:**
+
+```javascript
+const transferFunds = db.transaction((fromAccount, toAccount, amount) => {
+  const debit = db.prepare('UPDATE accounts SET balance = balance - ? WHERE id = ?');
+  const credit = db.prepare('UPDATE accounts SET balance = balance + ? WHERE id = ?');
+  const getBalance = db.prepare('SELECT balance FROM accounts WHERE id = ?');
+  
+  // Check sufficient funds
+  const fromBalance = getBalance.get(fromAccount).balance;
+  if (fromBalance < amount) {
+    throw new Error('Insufficient funds'); // Transaction will rollback
+  }
+  
+  // Perform transfer
+  debit.run(amount, fromAccount);
+  credit.run(amount, toAccount);
+  
+  // Verify the transfer
+  const newFromBalance = getBalance.get(fromAccount).balance;
+  const newToBalance = getBalance.get(toAccount).balance;
+  
+  return {
+    fromBalance: newFromBalance,
+    toBalance: newToBalance,
+    transferred: amount
+  };
+});
+
+try {
+  const result = transferFunds(1, 2, 100);
+  console.log('Transfer completed:', result);
+} catch (error) {
+  console.log('Transfer failed:', error.message);
+  // Database state unchanged due to automatic rollback
+}
+```
+
+### Transaction Function Properties
+
+Transaction functions expose properties for introspection and database access.
+
+```javascript { .api }
+interface TransactionFunction {
+  readonly database: Database; // Associated database instance
+  // All transaction type variants (deferred, immediate, exclusive) have same properties
+}
+```
+
+**Usage Examples:**
+
+```javascript
+const batchInsert = db.transaction((data) => {
+  // Function implementation
+});
+
+// Access the associated database
+console.log(batchInsert.database === db); // true
+
+// All transaction variants share the same database reference
+console.log(batchInsert.deferred.database === db); // true
+console.log(batchInsert.immediate.database === db); // true
+console.log(batchInsert.exclusive.database === db); // true
+
+// Check if currently in transaction during execution
+const checkTransactionStatus = db.transaction(() => {
+  console.log(db.inTransaction); // true during transaction execution
+});
+
+checkTransactionStatus();
+console.log(db.inTransaction); // false after transaction completes
+```
+
+### Transaction Best Practices
+
+Guidelines for effective transaction usage and performance optimization.
+
+**Performance Considerations:**
+
+```javascript
+// Good: Batch multiple operations in a single transaction
+const batchUserInsert = db.transaction((users) => {
+  const insert = db.prepare('INSERT INTO users (name, email) VALUES (?, ?)');
+  for (const user of users) {
+    insert.run(user.name, user.email);
+  }
+});
+
+// Bad: Individual transactions for each operation (slow)
+function insertUsersSlow(users) {
+  const insert = db.prepare('INSERT INTO users (name, email) VALUES (?, ?)');
+  for (const user of users) {
+    const singleInsert = db.transaction(() => {
+      insert.run(user.name, user.email);
+    });
+    singleInsert(); // Creates transaction overhead for each insert
+  }
+}
+
+// Good: Short-lived transactions
+const quickUpdate = db.transaction((id, newValue) => {
+  db.prepare('UPDATE table SET value = ? WHERE id = ?').run(newValue, id);
+});
+
+// Avoid: Long-running transactions that hold locks
+const avoidLongTransaction = db.transaction(() => {
+  // Don't do this - holds database locks too long
+  for (let i = 0; i < 1000000; i++) {
+    // Long-running computation
+    heavyComputation();
+  }
+  db.prepare('INSERT INTO results VALUES (?)').run(result);
+});
+```
+
+**Error Handling Patterns:**
+
+```javascript
+// Pattern: Specific error handling with graceful degradation
+const safeUserCreation = db.transaction((userData) => {
+  const insertUser = db.prepare('INSERT INTO users (name, email) VALUES (?, ?)');
+  const insertAuditLog = db.prepare('INSERT INTO audit_log (action, details) VALUES (?, ?)');
+  
+  try {
+    const result = insertUser.run(userData.name, userData.email);
+    
+    // Nested transaction for audit log (can fail without affecting user creation)
+    const logAudit = db.transaction(() => {
+      insertAuditLog.run('user_created', JSON.stringify(userData));
+    });
+    
+    try {
+      logAudit();
+    } catch (auditError) {
+      console.warn('Audit logging failed:', auditError.message);
+      // User creation still succeeds
+    }
+    
+    return result.lastInsertRowid;
+  } catch (error) {
+    console.error('User creation failed:', error.message);
+    throw error; // Re-throw to trigger rollback
+  }
+});
+```
+
+### Manual Transaction Control
+
+While transaction functions are recommended, manual transaction control is also possible.
+
+```javascript
+// Manual transaction control (not recommended with transaction functions)
+db.exec('BEGIN');
+try {
+  db.prepare('INSERT INTO users (name) VALUES (?)').run('John');
+  db.prepare('INSERT INTO profiles (user_id) VALUES (?)').run(1);
+  db.exec('COMMIT');
+} catch (error) {
+  db.exec('ROLLBACK');
+  throw error;
+}
+
+// Warning: Don't mix manual control with transaction functions
+const mixedApproach = db.transaction(() => {
+  // Don't use raw COMMIT/ROLLBACK inside transaction functions
+  // db.exec('COMMIT'); // This will cause issues
+});
+```

+# User-Defined Functions
+
+Extension system for creating custom SQL functions, aggregate functions, and virtual tables to extend SQLite functionality.
+
+## Capabilities
+
+### User-Defined Functions
+
+Create custom SQL functions that can be called from within SQL queries.
+
+```javascript { .api }
+/**
+ * Define user-defined function
+ * @param {string} name - Function name (used in SQL queries)
+ * @param {Object} [options] - Function configuration options
+ * @param {Function} fn - JavaScript function implementation
+ * @returns {Database} Database instance for chaining
+ */
+function(name, options, fn);
+
+interface FunctionOptions {
+  safeIntegers?: boolean; // Use safe integers for this function (default: database setting)
+  deterministic?: boolean; // Function is deterministic (default: false)
+  directOnly?: boolean;   // Function can only be called directly, not in triggers/views (default: false) 
+  varargs?: boolean;      // Function accepts variable arguments (default: false)
+}
+```
+
+**Usage Examples:**
+
+```javascript
+// Simple string function
+db.function('reverse', (str) => {
+  return typeof str === 'string' ? str.split('').reverse().join('') : null;
+});
+
+// Use in SQL query
+const result = db.prepare('SELECT reverse(name) as reversed_name FROM users').all();
+console.log(result); // [{ reversed_name: 'ecilA' }, { reversed_name: 'boB' }, ...]
+
+// Math function with multiple parameters
+db.function('pythagoras', (a, b) => {
+  if (typeof a !== 'number' || typeof b !== 'number') return null;
+  return Math.sqrt(a * a + b * b);
+});
+
+const distance = db.prepare('SELECT pythagoras(3, 4) as distance').get();
+console.log(distance.distance); // 5
+
+// Function with options
+db.function('random_int', {
+  deterministic: false,  // Result can vary between calls
+  directOnly: true      // Can't be used in triggers or views
+}, (min, max) => {
+  if (typeof min !== 'number' || typeof max !== 'number') return null;
+  return Math.floor(Math.random() * (max - min + 1)) + min;
+});
+
+// Variable arguments function
+db.function('concat_with_separator', {
+  varargs: true
+}, (separator, ...args) => {
+  if (typeof separator !== 'string') return null;
+  return args.filter(arg => arg != null).join(separator);
+});
+
+const concatenated = db.prepare("SELECT concat_with_separator(' | ', name, email, city) as info FROM users").all();
+```
+
+### Aggregate Functions
+
+Create custom aggregate functions for GROUP BY operations and window functions.
+
+```javascript { .api }
+/**
+ * Define user-defined aggregate function
+ * @param {string} name - Aggregate function name
+ * @param {Object} options - Aggregate configuration (required)
+ * @returns {Database} Database instance for chaining
+ */
+aggregate(name, options);
+
+interface AggregateOptions {
+  start?: any;            // Initial accumulator value (default: null)
+  step: Function;         // Step function called for each row (required)
+  inverse?: Function;     // Inverse function for window functions (optional)
+  result?: Function;      // Final result transformation function (optional)
+  safeIntegers?: boolean; // Use safe integers (default: database setting)
+  deterministic?: boolean; // Function is deterministic (default: false)
+  directOnly?: boolean;   // Function can only be called directly (default: false)
+  varargs?: boolean;      // Function accepts variable arguments (default: false)
+}
+```
+
+**Usage Examples:**
+
+```javascript
+// String concatenation aggregate
+db.aggregate('group_concat_custom', {
+  start: '',
+  step: (accumulator, value) => {
+    if (value == null) return accumulator;
+    return accumulator === '' ? String(value) : accumulator + ', ' + String(value);
+  },
+  result: (accumulator) => accumulator || null
+});
+
+const groupedNames = db.prepare('SELECT group_concat_custom(name) as names FROM users').get();
+console.log(groupedNames.names); // "Alice, Bob, Charlie"
+
+// Mathematical aggregate - geometric mean
+db.aggregate('geometric_mean', {
+  start: { product: 1, count: 0 },
+  step: (accumulator, value) => {
+    if (typeof value !== 'number' || value <= 0) return accumulator;
+    return {
+      product: accumulator.product * value,
+      count: accumulator.count + 1
+    };
+  },
+  result: (accumulator) => {
+    if (accumulator.count === 0) return null;
+    return Math.pow(accumulator.product, 1 / accumulator.count);
+  }
+});
+
+const geometricMean = db.prepare('SELECT geometric_mean(value) as geo_mean FROM measurements').get();
+
+// Window function with inverse (for sliding windows)
+db.aggregate('running_average', {
+  start: { sum: 0, count: 0 },
+  step: (accumulator, value) => {
+    if (typeof value !== 'number') return accumulator;
+    return {
+      sum: accumulator.sum + value,
+      count: accumulator.count + 1
+    };
+  },
+  inverse: (accumulator, value) => {
+    if (typeof value !== 'number') return accumulator;
+    return {
+      sum: accumulator.sum - value,
+      count: accumulator.count - 1
+    };
+  },
+  result: (accumulator) => {
+    return accumulator.count > 0 ? accumulator.sum / accumulator.count : null;
+  }
+});
+
+// Use as window function
+const runningAverage = db.prepare(`
+  SELECT value, 
+         running_average(value) OVER (ORDER BY id ROWS BETWEEN 2 PRECEDING AND CURRENT ROW) as avg_3
+  FROM measurements 
+  ORDER BY id
+`).all();
+
+// Complex aggregate with multiple parameters
+db.aggregate('weighted_average', {
+  start: { weightedSum: 0, totalWeight: 0 },
+  step: (accumulator, value, weight) => {
+    if (typeof value !== 'number' || typeof weight !== 'number' || weight <= 0) {
+      return accumulator;
+    }
+    return {
+      weightedSum: accumulator.weightedSum + (value * weight),
+      totalWeight: accumulator.totalWeight + weight
+    };
+  },
+  result: (accumulator) => {
+    return accumulator.totalWeight > 0 ? accumulator.weightedSum / accumulator.totalWeight : null;
+  }
+});
+```
+
+### Virtual Tables
+
+Create virtual tables that generate data dynamically or interface with external data sources.
+
+```javascript { .api }
+/**
+ * Define virtual table module
+ * @param {string} name - Module name
+ * @param {Function|Object} factory - Factory function or eponymous table definition
+ * @returns {Database} Database instance for chaining
+ */
+table(name, factory);
+
+// Factory function signature
+interface TableFactory {
+  (moduleName: string, databaseName: string, tableName: string, ...args): TableDefinition;
+}
+
+// Table definition object
+interface TableDefinition {
+  columns: string[];           // Column names (required)
+  rows: GeneratorFunction;     // Generator function yielding rows (required)
+  parameters?: string[];       // Parameter names (optional, inferred from rows.length)
+  safeIntegers?: boolean;     // Use safe integers (default: database setting)
+  directOnly?: boolean;       // Table can only be accessed directly (default: false)
+}
+```
+
+**Usage Examples:**
+
+```javascript
+// Simple eponymous-only virtual table (no factory)
+db.table('fibonacci', {
+  columns: ['value', 'position'],
+  *rows(limit = 10) {
+    let a = 0, b = 1, position = 0;
+    while (position < limit) {
+      yield [a, position];
+      [a, b] = [b, a + b];
+      position++;
+    }
+  }
+});
+
+// Use the virtual table
+const fibNumbers = db.prepare('SELECT * FROM fibonacci(15)').all();
+console.log(fibNumbers); // First 15 Fibonacci numbers
+
+// Factory-based virtual table for flexibility
+db.table('sequence_generator', function(moduleName, databaseName, tableName, type) {
+  return {
+    columns: ['value', 'index'],
+    parameters: ['start', 'end', 'step'],
+    *rows(start, end, step = 1) {
+      let index = 0;
+      for (let value = start; value <= end; value += step) {
+        if (type === 'even' && value % 2 !== 0) continue;
+        if (type === 'odd' && value % 2 === 0) continue;
+        yield { value, index: index++ };
+      }
+    }
+  };
+});
+
+// Create specific table instances
+db.exec('CREATE VIRTUAL TABLE even_numbers USING sequence_generator(even)');
+db.exec('CREATE VIRTUAL TABLE odd_numbers USING sequence_generator(odd)');
+
+// Query the virtual tables
+const evenNumbers = db.prepare('SELECT * FROM even_numbers(2, 20, 2)').all();
+const oddNumbers = db.prepare('SELECT * FROM odd_numbers(1, 19, 2)').all();
+
+// Complex virtual table with external data
+db.table('file_system', {
+  columns: ['name', 'size', 'type', 'modified'],
+  parameters: ['directory'],
+  *rows(directory = '.') {
+    const fs = require('fs');
+    const path = require('path');
+    
+    try {
+      const entries = fs.readdirSync(directory, { withFileTypes: true });
+      for (const entry of entries) {
+        const fullPath = path.join(directory, entry.name);
+        const stats = fs.statSync(fullPath);
+        
+        yield {
+          name: entry.name,
+          size: stats.size,
+          type: entry.isDirectory() ? 'directory' : 'file',
+          modified: stats.mtime.toISOString()
+        };
+      }
+    } catch (error) {
+      // Handle directory access errors gracefully
+      console.warn(`Cannot read directory ${directory}:`, error.message);
+    }
+  }
+});
+
+// Query file system
+const files = db.prepare(`
+  SELECT name, size, type 
+  FROM file_system('/usr/local/bin') 
+  WHERE type = 'file' AND size > 1000 
+  ORDER BY size DESC
+`).all();
+
+// Virtual table with JSON data processing
+db.table('json_parser', {

+          if (path === '$' || fullPath.startsWith(path)) {
+            yield {
+              key: fullPath,

+    }
+  }
+});
+
+// Parse JSON data
+const jsonData = '{"users": [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}]}';
+const parsedData = db.prepare(`
+  SELECT key, value, type 
+  FROM json_parser(?, '$.users') 
+  WHERE type != 'object'
+`).all(jsonData);
+```
+
+### Function and Table Management
+
+Utilities for managing user-defined functions and virtual tables.
+
+**Function Replacement:**
+
+```javascript
+// Functions can be replaced by redefining
+db.function('my_function', () => 'version 1');
+let result1 = db.prepare('SELECT my_function() as result').get();
+console.log(result1.result); // "version 1"
+
+db.function('my_function', () => 'version 2');
+let result2 = db.prepare('SELECT my_function() as result').get();
+console.log(result2.result); // "version 2"
+
+// Remove function by providing null
+db.function('my_function', null);
+// Now my_function() is no longer available
+```
+
+**Error Handling in Functions:**
+
+```javascript
+// Handle errors gracefully in user-defined functions
+db.function('safe_divide', (a, b) => {
+  if (typeof a !== 'number' || typeof b !== 'number') return null;
+  if (b === 0) return null; // Return null for division by zero
+  return a / b;
+});
+
+// Function that throws errors
+db.function('strict_divide', (a, b) => {
+  if (typeof a !== 'number' || typeof b !== 'number') {
+    throw new Error('Arguments must be numbers');
+  }
+  if (b === 0) {
+    throw new Error('Division by zero');
+  }
+  return a / b;
+});
+
+// Errors in functions become SQL errors
+try {
+  db.prepare('SELECT strict_divide(10, 0)').get();
+} catch (error) {
+  console.log(error.message); // "Division by zero"
+}
+```
+
+**Performance Considerations:**
+
+```javascript
+// Use deterministic flag for cacheable functions
+db.function('expensive_calculation', {
+  deterministic: true // SQLite can cache results
+}, (input) => {
+  // Expensive computation that always returns same result for same input
+  return heavyMathOperation(input);
+});
+
+// Use directOnly for security-sensitive functions
+db.function('get_secret', {
+  directOnly: true // Prevents use in triggers, views, or stored procedures
+}, () => {
+  return process.env.SECRET_KEY;
+});
+
+// Optimize virtual tables for large datasets
+db.table('large_dataset', {
+  columns: ['id', 'data'],
+  *rows(limit = 1000000) {
+    for (let i = 0; i < limit; i++) {
+      // Yield data incrementally to avoid memory issues
+      yield { id: i, data: `record_${i}` };
+      
+      // Optional: yield control periodically for very large datasets
+      if (i % 10000 === 0) {
+        setImmediate(() => {}); // Allow event loop to process other tasks
+      }
+    }
+  }
+});
+```

+# CLI Usage
+
+Jest provides a comprehensive command-line interface with over 70 options for controlling test execution, coverage collection, watch mode, output formatting, and project configuration.
+
+## Basic CLI Usage
+
+Jest can be run from the command line with various options:
+
+```bash
+# Run all tests
+jest
+
+# Run tests matching a pattern
+jest MyComponent
+
+# Run tests in a specific directory
+jest src/components
+
+# Run tests with coverage
+jest --coverage
+
+# Run tests in watch mode
+jest --watch
+```
+
+## CLI Options Reference
+
+### Test Execution Options
+
+Control how tests are discovered, executed, and filtered.
+
+```bash
+# Stop after N test failures
+jest --bail
+jest --bail=3
+
+# Find tests related to specified files
+jest --findRelatedTests src/utils.js src/components/Button.js
+
+# List all tests Jest will run without executing them
+jest --listTests
+
+# Only run tests related to changed files (requires git)
+jest --onlyChanged
+jest -o
+
+# Run only tests that failed in previous execution
+jest --onlyFailures
+jest -f
+
+# Don't fail when no tests are found
+jest --passWithNoTests
+
+# Run tests serially in current process instead of parallel workers
+jest --runInBand
+jest -i
+
+# Use exact file paths instead of patterns
+jest --runTestsByPath path/to/test1.js path/to/test2.js
+
+# Run tests matching name pattern (regex)
+jest --testNamePattern="should add"
+jest -t "user login"
+
+# Regexp patterns for test file paths
+jest --testPathPatterns="__tests__.*\.js$"
+
+# Override testRegex configuration
+jest --testRegex=".*\.(test|spec)\.(js|ts)$"
+
+# Set default test timeout in milliseconds
+jest --testTimeout=10000
+```
+
+### Watch Mode Options
+
+Configure file watching and automatic test re-execution.
+
+```bash
+# Watch files and rerun related tests on changes
+jest --watch
+
+# Watch files and rerun all tests on changes
+jest --watchAll
+
+# Ignore patterns for watch mode
+jest --watchPathIgnorePatterns="node_modules" --watchPathIgnorePatterns="build"
+```
+
+## Testing Options
+
+### Test Selection and Filtering
+
+```bash
+# Run only tests that failed in the previous run
+jest --onlyFailures
+
+# Run only tests related to changed files (requires git)
+jest --onlyChanged
+
+# Run tests related to specific files
+jest --findRelatedTests src/utils.js src/components/Button.js
+
+# Run tests matching a name pattern
+jest --testNamePattern="should render correctly"
+
+# List all tests Jest would run without executing them
+jest --listTests
+
+# Run tests by exact file paths instead of patterns
+jest --runTestsByPath
+```
+
+### Test Execution Control
+
+```bash
+# Stop after N test failures
+jest --bail
+jest --bail=3
+
+# Run tests serially in the current process
+jest --runInBand
+
+# Set maximum number of worker processes
+jest --maxWorkers=4
+jest --maxWorkers=50%
+
+# Set default timeout for tests
+jest --testTimeout=10000
+
+# Don't fail when no tests are found
+jest --passWithNoTests
+```
+
+## Coverage Options
+
+### Basic Coverage
+
+```bash
+# Collect and report test coverage
+jest --coverage
+jest --collectCoverage  # equivalent
+
+# Specify coverage output directory
+jest --coverageDirectory=coverage-report
+
+# Choose coverage provider
+jest --coverageProvider=babel
+jest --coverageProvider=v8
+```
+
+### Coverage Configuration
+
+```bash
+# Collect coverage from specific files
+jest --collectCoverageFrom="src/**/*.js" --collectCoverageFrom="!src/**/*.test.js"
+
+# Ignore patterns for coverage
+jest --coveragePathIgnorePatterns=node_modules --coveragePathIgnorePatterns=build
+
+# Specify coverage reporters
+jest --coverageReporters=text --coverageReporters=html --coverageReporters=lcov
+
+# Set coverage thresholds (will fail if not met)
+jest --coverageThreshold='{"global":{"branches":80,"functions":80,"lines":80,"statements":80}}'
+```
+
+## Output and Reporting
+
+### Output Formats
+
+```bash
+# Output results in JSON format
+jest --json
+
+# Write JSON output to a file
+jest --json --outputFile=test-results.json
+
+# Verbose output showing individual test results
+jest --verbose
+
+# Silent mode - prevent tests from printing to console
+jest --silent
+
+# Disable stack traces in test output
+jest --noStackTrace
+
+# Force colored output
+jest --colors
+```
+
+### Advanced Output Control
+
+```bash
+# Log heap usage after each test
+jest --logHeapUsage
+
+# Detect and report memory leaks (experimental)
+jest --detectLeaks
+
+# Detect handles that prevent Jest from exiting
+jest --detectOpenHandles
+
+# Force Jest to exit after tests complete
+jest --forceExit
+```
+
+## Configuration Options
+
+### Configuration Sources
+
+```bash
+# Use specific config file
+jest --config=jest.config.js
+jest --config=package.json
+
+# Provide configuration as JSON string
+jest --config='{"testEnvironment":"node"}'
+
+# Set root directory
+jest --rootDir=/path/to/project
+
+# Specify multiple root directories
+jest --roots=src --roots=lib
+
+# Run tests for multiple projects
+jest --projects=project1 --projects=project2
+```
+
+### Environment and Setup
+
+```bash
+# Specify test environment
+jest --testEnvironment=node
+jest --testEnvironment=jsdom
+
+# Clear all mocks before each test
+jest --clearMocks
+
+# Reset module registry before each test
+jest --resetModules
+
+# Restore mocks after each test
+jest --restoreMocks
+```
+
+## Cache Management
+
+```bash
+# Use the transform cache (default: true)
+jest --cache
+
+# Disable the transform cache
+jest --no-cache
+
+# Specify cache directory
+jest --cacheDirectory=/tmp/jest-cache
+
+# Clear cache and exit (useful for CI)
+jest --clearCache
+```
+
+## Advanced Options
+
+### Development and Debugging
+
+```bash
+# Enable debug mode
+jest --debug
+
+# Throw error on deprecated API usage
+jest --errorOnDeprecated
+
+# Update snapshots
+jest --updateSnapshot
+
+# Randomize test order within files
+jest --randomize
+
+# Set seed for test randomization
+jest --seed=12345
+```
+
+### Performance and Concurrency
+
+```bash
+# Set maximum concurrent tests when using test.concurrent
+jest --maxConcurrency=5
+
+# Use specific number of workers
+jest --maxWorkers=2
+
+# Run tests in band (single process) for debugging
+jest -i  # short for --runInBand
+```
+
+## Watch Mode Patterns
+
+When running in watch mode (`--watch` or `--watchAll`), Jest provides an interactive interface:
+
+```bash
+# Watch mode commands (available during watch mode):
+# Press 'a' to run all tests
+# Press 'f' to run only failed tests  
+# Press 'o' to only run tests related to changed files
+# Press 'p' to filter by a filename regex pattern
+# Press 't' to filter by a test name regex pattern
+# Press 'q' to quit watch mode
+# Press 'Enter' to trigger a test run
+```
+
+### Watch Mode Configuration
+
+```bash
+# Ignore patterns in watch mode
+jest --watch --watchPathIgnorePatterns=node_modules --watchPathIgnorePatterns=build
+
+# Watch all files (not just tracked by git)
+jest --watchAll
+
+# Combine with other options
+jest --watch --coverage --verbose
+```
+
+## CLI Argument Building Programmatically
+
+```typescript { .api }
+import { buildArgv } from 'jest';
+
+function buildArgv(maybeArgv?: Array<string>): Promise<Config.Argv>
+```
+
+You can build CLI arguments programmatically using the `buildArgv` function:
+
+```typescript
+import { buildArgv, runCLI } from 'jest';
+
+// Build arguments for CI environment
+const ciArgv = await buildArgv([
+  '--ci',
+  '--coverage',
+  '--json',
+  '--runInBand',
+  '--passWithNoTests',
+  '--outputFile=test-results.json'
+]);
+
+// Build arguments for development
+const devArgv = await buildArgv([
+  '--watch',
+  '--verbose',
+  '--testPathPatterns=src/'
+]);
+
+// Build arguments with coverage thresholds
+const strictArgv = await buildArgv([
+  '--coverage',
+  '--coverageThreshold={"global":{"branches":90,"functions":90,"lines":90,"statements":90}}'
+]);
+```
+
+## Common CLI Workflows
+
+### Continuous Integration
+
+```bash
+# Typical CI command
+jest --ci --coverage --json --runInBand --passWithNoTests --outputFile=results.json
+
+# With coverage enforcement
+jest --ci --coverage --coverageThreshold='{"global":{"branches":80,"functions":80,"lines":80,"statements":80}}'
+```
+
+### Development Workflow
+
+```bash
+# Start development with watch mode
+jest --watch --verbose
+
+# Run tests for specific feature
+jest --watch --testPathPatterns=src/features/auth
+
+# Debug failing tests
+jest --runInBand --verbose --testNamePattern="failing test name"
+```
+
+### Pre-commit Checks
+
+```bash
+# Run only tests related to staged files
+jest --onlyChanged --passWithNoTests
+
+# Full validation with coverage
+jest --coverage --bail=1
+```
+
+### Performance Analysis
+
+```bash
+# Analyze test performance
+jest --verbose --logHeapUsage --detectLeaks
+
+# Profile with single worker for consistency  
+jest --runInBand --logHeapUsage
+```
+
+The Jest CLI provides comprehensive control over test execution, making it suitable for development, continuous integration, and automated testing workflows.

+
+### Configuration File Examples
+
+**Basic Configuration (jest.config.js):**
+
+```javascript
+module.exports = {
+  // Test discovery
+  testMatch: ["**/__tests__/**/*.js", "**/?(*.)+(spec|test).js"],
+  testPathIgnorePatterns: ["/node_modules/", "/build/"],
+  
+  // Test environment
+  testEnvironment: "jsdom",
+  
+  // Module resolution
+  moduleDirectories: ["node_modules", "src"],
+  moduleFileExtensions: ["js", "json", "jsx", "ts", "tsx"],
+  moduleNameMapper: {
+    "^@/(.*)$": "<rootDir>/src/$1",
+    "\\.(css|less|scss)$": "identity-obj-proxy"
+  },
+  
+  // Transforms
+  transform: {
+    "^.+\\.jsx?$": "babel-jest",
+    "^.+\\.tsx?$": "ts-jest"
+  },
+  
+  // Setup
+  setupFilesAfterEnv: ["<rootDir>/src/setupTests.js"],
+  
+  // Coverage
+  collectCoverage: true,
+  collectCoverageFrom: [
+    "src/**/*.{js,jsx,ts,tsx}",
+    "!src/**/*.d.ts",
+    "!src/index.js"
+  ],
+  coverageDirectory: "coverage",
+  coverageReporters: ["text", "lcov", "html"],
+  coverageThreshold: {
+    global: {
+      branches: 80,
+      functions: 80,
+      lines: 80,
+      statements: 80
+    }
+  }
+};
+```
+
+**TypeScript Configuration:**
+
+```javascript
+module.exports = {
+  preset: "ts-jest",
+  testEnvironment: "node",
+  
+  // TypeScript specific
+  globals: {
+    "ts-jest": {
+      tsconfig: "tsconfig.test.json"
+    }
+  },
+  
+  // Module resolution for TypeScript
+  moduleNameMapper: {
+    "^@/(.*)$": "<rootDir>/src/$1"
+  },
+  
+  // File extensions
+  moduleFileExtensions: ["ts", "tsx", "js", "jsx", "json"],
+  
+  // Transform configuration
+  transform: {
+    "^.+\\.tsx?$": "ts-jest"
+  },
+  
+  // Test files
+  testMatch: ["**/__tests__/**/*.ts", "**/?(*.)+(spec|test).ts"]
+};
+```
+
+**Multi-Project Configuration:**
+
+```javascript
+module.exports = {
+  projects: [
+    {
+      displayName: "client",
+      testMatch: ["<rootDir>/packages/client/**/*.test.js"],
+      testEnvironment: "jsdom",
+      setupFilesAfterEnv: ["<rootDir>/packages/client/src/setupTests.js"]
+    },
+    {
+      displayName: "server",
+      testMatch: ["<rootDir>/packages/server/**/*.test.js"],
+      testEnvironment: "node",
+      setupFilesAfterEnv: ["<rootDir>/packages/server/src/setupTests.js"]
+    },
+    {
+      displayName: "shared",
+      testMatch: ["<rootDir>/packages/shared/**/*.test.js"],
+      testEnvironment: "node"
+    }
+  ],
+  
+  // Global coverage settings
+  collectCoverage: true,
+  coverageDirectory: "coverage",
+  coverageReporters: ["text-summary", "html"]
+};
+```
+
+### Configuration Loading and Resolution
+
+Jest resolves configuration in the following order:
+
+1. `--config` CLI argument
+2. `jest.config.js` file
+3. `jest.config.ts` file
+4. `jest` field in `package.json`
+5. Default configuration
+
+**Programmatic Configuration:**
+
+```typescript
+import { runCLI, buildArgv } from "jest";
+
+// Override configuration programmatically
+async function runWithCustomConfig() {
+  const customConfig = {
+    testMatch: ["**/*.custom.test.js"],
+    testEnvironment: "node",
+    collectCoverage: true
+  };
+  
+  const argv = await buildArgv([
+    `--config=${JSON.stringify(customConfig)}`
+  ]);
+  
+  return runCLI(argv, [process.cwd()]);
+}
+
+// Merge with existing configuration
+async function extendConfiguration(baseConfigPath: string) {
+  const baseConfig = require(baseConfigPath);
+  
+  const extendedConfig = {
+    ...baseConfig,
+    collectCoverage: true,
+    coverageThreshold: {
+      global: {
+        branches: 90,
+        functions: 90,
+        lines: 90,
+        statements: 90
+      }
+    }
+  };
+  
+  const argv = await buildArgv([
+    `--config=${JSON.stringify(extendedConfig)}`
+  ]);
+  
+  return runCLI(argv, [process.cwd()]);
+}
+```
+
+### Environment-Specific Configuration
+
+**Development Configuration:**
+
+```javascript
+// jest.dev.config.js
+module.exports = {
+  ...require('./jest.config.js'),
+  
+  // Development specific settings
+  verbose: true,
+  collectCoverage: false,
+  watchAll: true,
+  
+  // Faster transforms for development
+  transform: {
+    "^.+\\.jsx?$": "babel-jest"
+  }
+};
+```
+
+**CI Configuration:**
+
+```javascript
+// jest.ci.config.js
+module.exports = {
+  ...require('./jest.config.js'),
+  
+  // CI specific settings
+  ci: true,
+  collectCoverage: true,
+  coverageReporters: ["text", "lcov"],
+  maxWorkers: "50%",
+  cache: false,
+  
+  // Strict coverage requirements
+  coverageThreshold: {
+    global: {
+      branches: 90,
+      functions: 90,
+      lines: 90,
+      statements: 90
+    }
+  }
+};
+```
+
+### Advanced Configuration Patterns
+
+**Dynamic Configuration:**
+
+```javascript
+// jest.config.js
+const isCI = process.env.CI === "true";
+const isDevelopment = process.env.NODE_ENV === "development";
+
+module.exports = {
+  testMatch: ["**/__tests__/**/*.js", "**/?(*.)+(spec|test).js"],
+  
+  // Dynamic coverage settings
+  collectCoverage: isCI,
+  coverageReporters: isCI 
+    ? ["text", "lcov"] 
+    : ["text-summary"],
+  
+  // Dynamic worker settings
+  maxWorkers: isCI ? "50%" : 1,
+  
+  // Development specific settings
+  verbose: isDevelopment,
+  silent: isCI,
+  
+  // Environment specific transforms
+  transform: isDevelopment 
+    ? { "^.+\\.jsx?$": "babel-jest" }
+    : { "^.+\\.jsx?$": ["babel-jest", { cacheDirectory: false }] }
+};
+```
+
+**Conditional Test Patterns:**
+
+```javascript
+module.exports = {
+  // Base test patterns
+  testMatch: ["**/__tests__/**/*.js"],
+  
+  // Add integration tests in CI
+  ...(process.env.CI && {
+    testMatch: [
+      "**/__tests__/**/*.js",
+      "**/integration/**/*.test.js"
+    ]
+  }),
+  
+  // Add e2e tests for full test runs
+  ...(process.env.FULL_TEST_SUITE && {
+    testMatch: [
+      "**/__tests__/**/*.js",
+      "**/integration/**/*.test.js",
+      "**/e2e/**/*.test.js"
+    ]
+  })
+};
+```
+
+Jest's configuration system provides complete control over test execution behavior, enabling optimization for different environments and use cases while maintaining consistency across development workflows.

+# Test Discovery
+
+Jest's test discovery system provides advanced capabilities for finding, filtering, and organizing test files with pattern matching, dependency tracking, and change detection for optimized test runs.
+
+## Capabilities
+
+### SearchSource Class
+
+The SearchSource class is the core component responsible for test file discovery and filtering.
+
+```typescript { .api }
+/**
+ * Core class for finding and filtering test files
+ */
+class SearchSource {
+  constructor(context: TestContext);
+  
+  /**
+   * Determines if a given path is a test file based on configuration
+   * @param path - File path to check
+   * @returns True if the path matches test file patterns
+   */
+  isTestFilePath(path: string): boolean;
+  
+  /**
+   * Finds tests matching the given path patterns
+   * @param testPathPatternsExecutor - Pattern executor for test paths
+   * @returns Search results with matching tests
+   */
+  findMatchingTests(testPathPatternsExecutor: TestPathPatternsExecutor): SearchResult;
+  
+  /**
+   * Finds tests by exact file paths
+   * @param paths - Array of exact file paths
+   * @returns Search results with specified test files
+   */
+  findTestsByPaths(paths: Array<string>): SearchResult;
+  
+  /**
+   * Finds tests related to the given source file paths
+   * @param allPaths - Set of source file paths
+   * @param collectCoverage - Whether to collect coverage information
+   * @returns Promise resolving to search results with related tests
+   */
+  findRelatedTests(allPaths: Set<string>, collectCoverage: boolean): Promise<SearchResult>;
+  
+  /**
+   * Main method to get test paths based on configuration and options
+   * @param globalConfig - Global Jest configuration
+   * @param projectConfig - Project-specific configuration
+   * @param changedFiles - Optional changed files information
+   * @param filter - Optional filter function
+   * @returns Promise resolving to comprehensive search results
+   */
+  getTestPaths(
+    globalConfig: Config.GlobalConfig,
+    projectConfig: Config.ProjectConfig,
+    changedFiles?: ChangedFiles,
+    filter?: Filter
+  ): Promise<SearchResult>;
+}
+
+interface SearchResult {
+  noSCM?: boolean;
+  stats?: Stats;
+  collectCoverageFrom?: Set<string>;
+  tests: Array<Test>;
+  total?: number;
+}
+
+interface Stats {
+  roots: number;
+  testMatch: number;
+  testPathIgnorePatterns: number;
+  testRegex: number;
+  testPathPatterns?: number;
+}
+```
+
+**Usage Examples:**
+
+```typescript
+import { SearchSource } from "jest";
+
+// Create SearchSource instance
+const searchSource = new SearchSource(testContext);
+
+// Find all test files
+const allTests = await searchSource.getTestPaths(
+  globalConfig,
+  projectConfig
+);
+
+console.log(`Found ${allTests.tests.length} test files`);
+
+// Check if a file is a test file
+const isTest = searchSource.isTestFilePath("src/__tests__/utils.test.js");
+console.log(`Is test file: ${isTest}`);
+
+// Find tests related to changed source files
+const changedFiles = new Set(["src/utils.js", "src/components/Button.js"]);
+const relatedTests = await searchSource.findRelatedTests(changedFiles, false);
+
+console.log(`Found ${relatedTests.tests.length} related tests`);
+```
+
+### Test Pattern Matching
+
+Advanced pattern matching for test file discovery:
+
+```typescript
+// Find tests by exact paths
+const specificTests = searchSource.findTestsByPaths([
+  "src/components/Button.test.js",
+  "src/utils/helpers.test.js"
+]);
+
+// Find tests matching patterns (via getTestPaths)
+const patternTests = await searchSource.getTestPaths(
+  {
+    ...globalConfig,
+    testPathPatterns: ["components", "utils"]
+  },
+  projectConfig
+);
+```
+
+### Change Detection Integration
+
+Optimize test runs by finding tests related to changed files:
+
+```typescript
+import { SearchSource } from "jest";
+
+async function runTestsForChangedFiles(
+  searchSource: SearchSource,
+  changedFiles: string[]
+) {
+  // Find tests related to changed source files
+  const relatedTests = await searchSource.findRelatedTests(
+    new Set(changedFiles),
+    true // collectCoverage
+  );
+  
+  if (relatedTests.tests.length === 0) {
+    console.log("No tests found for changed files");
+    return null;
+  }
+  
+  return relatedTests;
+}
+
+// Usage with git integration
+async function findTestsForGitChanges() {
+  const changedFiles = await getChangedFilesFromGit();
+  const relatedTests = await searchSource.findRelatedTests(
+    new Set(changedFiles),
+    false
+  );
+  
+  return relatedTests.tests.map(test => test.path);
+}
+```
+
+### Custom Test Discovery Patterns
+
+Implement custom test discovery logic:
+
+```typescript
+import { SearchSource } from "jest";
+
+class CustomTestDiscovery {
+  constructor(private searchSource: SearchSource) {}
+  
+  async findTestsByFeature(featureName: string) {
+    // Find all tests
+    const allTests = await this.searchSource.getTestPaths(
+      globalConfig,
+      projectConfig
+    );
+    
+    // Filter by feature directory or naming convention
+    const featureTests = allTests.tests.filter(test =>
+      test.path.includes(`features/${featureName}`) ||
+      test.path.includes(`${featureName}.test.`)
+    );
+    
+    return {
+      ...allTests,
+      tests: featureTests,
+      total: featureTests.length
+    };
+  }
+  
+  async findTestsByTags(tags: string[]) {
+    const allTests = await this.searchSource.getTestPaths(
+      globalConfig,
+      projectConfig
+    );
+    
+    // Filter tests based on file content or naming patterns
+    const taggedTests = allTests.tests.filter(test => {
+      const filename = test.path.toLowerCase();
+      return tags.some(tag => filename.includes(tag.toLowerCase()));
+    });
+    
+    return {
+      ...allTests,
+      tests: taggedTests,
+      total: taggedTests.length
+    };
+  }
+  
+  async findSlowTests(thresholdMs: number = 1000) {
+    // This would typically require historical test timing data
+    // Implementation would depend on custom test result storage
+    const allTests = await this.searchSource.getTestPaths(
+      globalConfig,
+      projectConfig
+    );
+    
+    // Example: identify tests by naming convention
+    const potentiallySlowTests = allTests.tests.filter(test =>
+      test.path.includes("integration") ||
+      test.path.includes("e2e") ||
+      test.path.includes("slow")
+    );
+    
+    return {
+      ...allTests,
+      tests: potentiallySlowTests,
+      total: potentiallySlowTests.length
+    };
+  }
+}
+```
+
+### Performance Optimization
+
+Optimize test discovery for large codebases:
+
+```typescript
+async function optimizedTestDiscovery(
+  searchSource: SearchSource,
+  options: {
+    useCache?: boolean;
+    maxFiles?: number;
+    changedFilesOnly?: boolean;
+  } = {}
+) {
+  if (options.changedFilesOnly) {
+    // Only find tests related to changed files
+    const changedFiles = await getChangedFiles();
+    return searchSource.findRelatedTests(new Set(changedFiles), false);
+  }
+  
+  // Get all tests with potential limits
+  const allTests = await searchSource.getTestPaths(
+    globalConfig,
+    projectConfig
+  );
+  
+  if (options.maxFiles && allTests.tests.length > options.maxFiles) {
+    // Limit test count for performance
+    const limitedTests = allTests.tests.slice(0, options.maxFiles);
+    console.warn(`Limited to ${options.maxFiles} tests (found ${allTests.tests.length})`);
+    
+    return {
+      ...allTests,
+      tests: limitedTests,
+      total: limitedTests.length
+    };
+  }
+  
+  return allTests;
+}
+```
+
+## Integration with Test Execution
+
+The SearchSource integrates seamlessly with Jest's test execution pipeline:
+
+```typescript
+import { SearchSource, createTestScheduler } from "jest";
+
+async function discoverAndRunTests() {
+  // 1. Discover tests
+  const searchSource = new SearchSource(testContext);
+  const searchResult = await searchSource.getTestPaths(
+    globalConfig,
+    projectConfig
+  );
+  
+  // 2. Create scheduler
+  const scheduler = await createTestScheduler(globalConfig, schedulerContext);
+  
+  // 3. Execute discovered tests
+  const results = await scheduler.scheduleTests(
+    searchResult.tests,
+    testWatcher
+  );
+  
+  return results;
+}
+```
+
+Jest's test discovery system provides the foundation for intelligent test execution, enabling optimized test runs based on code changes, file patterns, and custom discovery logic.

+# Test Runner
+
+Jest's test runner provides both programmatic and CLI-based test execution with comprehensive configuration options, result aggregation, and performance optimization through parallel execution.
+
+## Capabilities
+
+### Programmatic Test Execution
+
+Run Jest tests programmatically with full control over configuration and execution parameters.
+
+```typescript { .api }
+/**
+ * Runs Jest CLI programmatically with specified configuration and projects
+ * @param argv - Command line arguments and configuration
+ * @param projects - Array of project paths to run tests on
+ * @returns Promise resolving to test results and global configuration
+ */
+function runCLI(
+  argv: Config.Argv,
+  projects: Array<string>
+): Promise<{
+  results: AggregatedResult;
+  globalConfig: Config.GlobalConfig;
+}>;
+
+interface AggregatedResult {
+  numTotalTests: number;
+  numPassedTests: number;
+  numFailedTests: number;
+  numPendingTests: number;
+  numRuntimeErrorTestSuites: number;
+  numTotalTestSuites: number;
+  numPassedTestSuites: number;
+  numFailedTestSuites: number;
+  numPendingTestSuites: number;
+  openHandles: Array<Error>;
+  snapshot: SnapshotSummary;
+  success: boolean;
+  startTime: number;
+  testResults: Array<TestResult>;
+  wasInterrupted: boolean;
+}
+```
+
+**Usage Examples:**
+
+```typescript
+import { runCLI, buildArgv } from "jest";
+
+// Basic test run
+async function runTests() {
+  const argv = await buildArgv(["--testMatch=**/*.test.js"]);
+  const { results, globalConfig } = await runCLI(argv, ["./src"]);
+  
+  console.log(`${results.numPassedTests}/${results.numTotalTests} tests passed`);
+  
+  if (!results.success) {
+    console.error("Tests failed!");
+    process.exit(1);
+  }
+}
+
+// Run with coverage and JSON output
+async function runTestsWithCoverage() {
+  const argv = await buildArgv([
+    "--coverage",
+    "--json",
+    "--outputFile=test-results.json"
+  ]);
+  
+  const { results } = await runCLI(argv, [process.cwd()]);
+  return results;
+}
+
+// Run specific test files
+async function runSpecificTests(testFiles: string[]) {
+  const argv = await buildArgv([
+    "--runTestsByPath",
+    ...testFiles
+  ]);
+  
+  const { results } = await runCLI(argv, [process.cwd()]);
+  return results;
+}
+```
+
+### CLI Entry Point
+
+Main CLI runner that handles argument parsing and delegates to the programmatic API.
+
+```typescript { .api }
+/**
+ * Main CLI entry point for Jest
+ * @param maybeArgv - Optional command line arguments (defaults to process.argv.slice(2))
+ * @param project - Optional project path
+ * @returns Promise that resolves when Jest execution completes
+ */
+function run(maybeArgv?: Array<string>, project?: string): Promise<void>;
+```
+
+**Usage Example:**
+
+```typescript
+import { run } from "jest";
+
+// Run Jest with default arguments
+await run();
+
+// Run Jest with custom arguments
+await run(["--watch", "--testPathPatterns=src/components"]);
+
+// Run Jest for specific project
+await run(["--coverage"], "./my-project");
+```
+
+### Argument Parsing and Validation
+
+Parse and validate command line arguments for Jest execution.
+
+```typescript { .api }
+/**
+ * Builds and validates command line arguments for Jest
+ * @param maybeArgv - Optional command line arguments
+ * @returns Promise resolving to parsed and validated arguments
+ */
+function buildArgv(maybeArgv?: Array<string>): Promise<Config.Argv>;
+
+interface Config.Argv {
+  // Test execution options
+  all?: boolean;
+  bail?: boolean | number;
+  findRelatedTests?: boolean;
+  listTests?: boolean;
+  onlyChanged?: boolean;
+  onlyFailures?: boolean;
+  passWithNoTests?: boolean;
+  runInBand?: boolean;
+  runTestsByPath?: boolean;
+  testNamePattern?: string;
+  testPathPatterns?: Array<string>;
+  testTimeout?: number;
+  
+  // Watch mode options
+  watch?: boolean;
+  watchAll?: boolean;
+  watchPathIgnorePatterns?: Array<string>;
+  
+  // Coverage options
+  collectCoverage?: boolean;
+  coverage?: boolean;
+  collectCoverageFrom?: Array<string>;
+  coverageDirectory?: string;
+  coveragePathIgnorePatterns?: Array<string>;
+  coverageProvider?: "babel" | "v8";
+  coverageReporters?: Array<string>;
+  coverageThreshold?: Record<string, number>;
+  
+  // Output options
+  json?: boolean;
+  outputFile?: string;
+  verbose?: boolean;
+  silent?: boolean;
+  noStackTrace?: boolean;
+  color?: boolean;
+  colors?: boolean;
+  
+  // Configuration options
+  config?: string;
+  rootDir?: string;
+  roots?: Array<string>;
+  projects?: Array<string>;
+  maxWorkers?: number | string;
+  cache?: boolean;
+  clearCache?: boolean;
+  debug?: boolean;
+  updateSnapshot?: boolean;
+}
+```
+
+### Integration Patterns
+
+Common patterns for integrating Jest into build tools and custom workflows:
+
+**Build Tool Integration:**
+
+```typescript
+import { runCLI, buildArgv } from "jest";
+
+async function buildToolIntegration(options: {
+  testFiles?: string[];
+  coverage?: boolean;
+  watch?: boolean;
+}) {
+  const args = [];
+  
+  if (options.coverage) args.push("--coverage");
+  if (options.watch) args.push("--watch");
+  if (options.testFiles) {

+# Test Scheduling
+
+Jest's test scheduling system manages test execution coordination, multi-process scheduling, reporter management, and comprehensive result aggregation for optimal performance and reporting.
+
+## Capabilities
+
+### TestScheduler Class
+
+The TestScheduler manages test execution scheduling and coordinates with reporters for comprehensive test result processing.
+
+```typescript { .api }
+/**
+ * Manages test execution scheduling and reporting
+ */
+class TestScheduler {
+  constructor(globalConfig: Config.GlobalConfig, context: TestSchedulerContext);
+  
+  /**
+   * Adds a reporter to the dispatcher
+   * @param reporter - Reporter instance to add
+   */
+  addReporter(reporter: Reporter): void;
+  
+  /**
+   * Removes a reporter from the dispatcher
+   * @param reporterConstructor - Constructor of reporter to remove
+   */
+  removeReporter(reporterConstructor: ReporterConstructor): void;
+  
+  /**
+   * Schedules and executes the given tests
+   * @param tests - Array of test files to execute
+   * @param watcher - Test watcher for watch mode integration
+   * @returns Promise resolving to aggregated test results
+   */
+  scheduleTests(tests: Array<Test>, watcher: TestWatcher): Promise<AggregatedResult>;
+}
+
+/**
+ * Factory function that creates a TestScheduler and sets up reporters
+ * @param globalConfig - Global Jest configuration
+ * @param context - Scheduler context including reporter and test runner contexts
+ * @returns Promise resolving to configured test scheduler
+ */
+function createTestScheduler(
+  globalConfig: Config.GlobalConfig,
+  context: TestSchedulerContext
+): Promise<TestScheduler>;
+
+type TestSchedulerContext = ReporterContext & TestRunnerContext;
+
+type ReporterConstructor = new (
+  globalConfig: Config.GlobalConfig,
+  reporterConfig: Record<string, unknown>,
+  reporterContext: ReporterContext,
+) => JestReporter;
+```
+
+**Usage Examples:**
+
+```typescript
+import { createTestScheduler, SearchSource } from "jest";
+
+// Create and configure test scheduler
+async function setupTestScheduler() {
+  const scheduler = await createTestScheduler(globalConfig, {
+    ...reporterContext,
+    ...testRunnerContext
+  });
+  
+  // Add custom reporter
+  scheduler.addReporter(new CustomReporter(globalConfig, {}, reporterContext));
+  
+  return scheduler;
+}
+
+// Execute tests with scheduler
+async function executeTests(testFiles: Array<Test>) {
+  const scheduler = await setupTestScheduler();
+  
+  const results = await scheduler.scheduleTests(
+    testFiles,
+    new TestWatcher({ isWatchMode: false })
+  );
+  
+  return results;
+}
+```
+
+### Test Execution Coordination
+
+The TestScheduler coordinates test execution across multiple processes and manages the complete test lifecycle.
+
+**Basic Test Scheduling:**
+
+```typescript
+import { createTestScheduler, SearchSource } from "jest";
+
+async function coordinateTestExecution() {
+  // 1. Discover tests
+  const searchSource = new SearchSource(testContext);
+  const searchResult = await searchSource.getTestPaths(
+    globalConfig,
+    projectConfig
+  );
+  
+  // 2. Create scheduler
+  const scheduler = await createTestScheduler(globalConfig, schedulerContext);
+  
+  // 3. Schedule and execute tests
+  const results = await scheduler.scheduleTests(
+    searchResult.tests,
+    new TestWatcher({ isWatchMode: false })
+  );
+  
+  console.log(`Executed ${results.numTotalTests} tests`);
+  console.log(`Passed: ${results.numPassedTests}`);
+  console.log(`Failed: ${results.numFailedTests}`);
+  
+  return results;
+}
+```
+
+### Reporter Management
+
+Manage test result reporting through dynamic reporter configuration.
+
+```typescript
+import { createTestScheduler } from "jest";
+
+// Custom reporter for specialized output
+class CustomReporter {
+  constructor(
+    private globalConfig: Config.GlobalConfig,
+    private options: Record<string, unknown>,
+    private context: ReporterContext
+  ) {}
+  
+  onRunStart(results: AggregatedResult, options: ReporterOnStartOptions) {
+    console.log("Starting test run...");
+  }
+  
+  onTestResult(test: Test, testResult: TestResult, results: AggregatedResult) {
+    if (testResult.testResults.some(result => result.status === "failed")) {
+      console.log(`❌ ${test.path}`);
+    } else {
+      console.log(`✅ ${test.path}`);
+    }
+  }
+  
+  onRunComplete(contexts: Set<TestContext>, results: AggregatedResult) {
+    console.log(`Test run completed: ${results.success ? "PASSED" : "FAILED"}`);
+  }
+}
+
+// Configure scheduler with custom reporters
+async function setupCustomReporting() {
+  const scheduler = await createTestScheduler(globalConfig, schedulerContext);
+  
+  // Add multiple reporters
+  scheduler.addReporter(new CustomReporter(globalConfig, {}, reporterContext));
+  scheduler.addReporter(new JSONReporter(globalConfig, { outputFile: "results.json" }, reporterContext));
+  
+  // Remove default reporter if needed
+  scheduler.removeReporter(DefaultReporter);
+  
+  return scheduler;
+}
+```
+
+### Multi-Process Coordination
+
+Handle test execution across multiple worker processes for optimal performance.
+
+```typescript
+import { createTestScheduler } from "jest";
+
+async function scheduleTestsWithWorkers(maxWorkers: number) {
+  const globalConfig = {
+    ...baseGlobalConfig,
+    maxWorkers,
+    runInBand: maxWorkers === 1
+  };
+  
+  const scheduler = await createTestScheduler(globalConfig, schedulerContext);
+  
+  // Configure for multi-process execution
+  const results = await scheduler.scheduleTests(
+    testFiles,
+    new TestWatcher({ 
+      isWatchMode: false,
+      // Additional options for worker coordination
+    })
+  );
+  
+  return results;
+}
+
+// Adaptive worker configuration
+async function adaptiveTestScheduling(testCount: number) {
+  // Determine optimal worker count based on test count and system resources
+  const maxWorkers = Math.min(
+    Math.max(1, Math.floor(testCount / 10)), // At least 10 tests per worker
+    require("os").cpus().length, // Don't exceed CPU count
+    8 // Cap at 8 workers
+  );
+  
+  return scheduleTestsWithWorkers(maxWorkers);
+}
+```
+
+### Watch Mode Integration
+
+Integrate with Jest's watch mode for automatic test re-execution.
+
+```typescript
+import { createTestScheduler } from "jest";
+import { TestWatcher } from "jest-watcher";
+
+async function scheduleTestsInWatchMode() {
+  const scheduler = await createTestScheduler(
+    { ...globalConfig, watch: true },
+    schedulerContext
+  );
+  
+  const watcher = new TestWatcher({ isWatchMode: true });
+  
+  // Watch mode provides automatic re-scheduling
+  const results = await scheduler.scheduleTests(testFiles, watcher);
+  
+  // In watch mode, this promise typically never resolves
+  // as Jest continues watching for file changes
+  return results;
+}
+
+// Custom watch mode logic
+class CustomTestWatcher extends TestWatcher {
+  constructor(options: { isWatchMode: boolean }) {
+    super(options);
+  }
+  
+  async onChange(changedFiles: Set<string>) {
+    console.log(`Files changed: ${Array.from(changedFiles).join(", ")}`);
+    
+    // Custom logic for determining which tests to re-run
+    const searchSource = new SearchSource(testContext);
+    const relatedTests = await searchSource.findRelatedTests(changedFiles, false);
+    
+    // Re-schedule only related tests
+    if (relatedTests.tests.length > 0) {
+      await this.scheduler.scheduleTests(relatedTests.tests, this);
+    }
+  }
+}
+```
+
+### Result Aggregation and Processing
+
+Process and aggregate test results for comprehensive reporting.
+
+```typescript
+import { createTestScheduler } from "jest";
+
+interface TestExecutionMetrics {
+  totalDuration: number;
+  averageTestDuration: number;
+  slowestTests: Array<{ path: string; duration: number }>;
+  fastestTests: Array<{ path: string; duration: number }>;
+  failureRate: number;
+  coveragePercentage?: number;
+}
+
+async function executeWithMetrics(tests: Array<Test>): Promise<{
+  results: AggregatedResult;
+  metrics: TestExecutionMetrics;
+}> {
+  const scheduler = await createTestScheduler(globalConfig, schedulerContext);
+  
+  const startTime = Date.now();
+  const results = await scheduler.scheduleTests(
+    tests,
+    new TestWatcher({ isWatchMode: false })
+  );
+  const totalDuration = Date.now() - startTime;
+  
+  // Calculate metrics
+  const testDurations = results.testResults
+    .flatMap(suite => suite.testResults)
+    .map(test => ({ path: test.title, duration: test.duration || 0 }))
+    .filter(test => test.duration > 0);
+  
+  const averageTestDuration = testDurations.length > 0
+    ? testDurations.reduce((sum, test) => sum + test.duration, 0) / testDurations.length
+    : 0;
+  
+  const sortedByDuration = testDurations.sort((a, b) => b.duration - a.duration);
+  
+  const metrics: TestExecutionMetrics = {
+    totalDuration,
+    averageTestDuration,
+    slowestTests: sortedByDuration.slice(0, 5),
+    fastestTests: sortedByDuration.slice(-5).reverse(),
+    failureRate: results.numTotalTests > 0 
+      ? results.numFailedTests / results.numTotalTests 
+      : 0,
+    coveragePercentage: results.coverageMap 
+      ? calculateCoveragePercentage(results.coverageMap)
+      : undefined
+  };
+  
+  return { results, metrics };
+}
+
+function calculateCoveragePercentage(coverageMap: any): number {
+  // Implementation would depend on coverage map structure
+  // This is a simplified example
+  const summary = coverageMap.getCoverageSummary?.();
+  return summary?.lines?.pct || 0;
+}
+```
+
+### Error Handling and Recovery
+
+Implement robust error handling for test scheduling failures.
+
+```typescript
+import { createTestScheduler } from "jest";
+
+async function robustTestScheduling(tests: Array<Test>) {
+  let scheduler: TestScheduler;
+  
+  try {
+    scheduler = await createTestScheduler(globalConfig, schedulerContext);
+  } catch (error) {
+    console.error("Failed to create test scheduler:", error);
+    throw new Error("Test scheduler initialization failed");
+  }
+  
+  // Add error reporter
+  scheduler.addReporter(new ErrorTrackingReporter());
+  
+  try {
+    const results = await scheduler.scheduleTests(
+      tests,
+      new TestWatcher({ isWatchMode: false })
+    );
+    
+    // Check for critical failures
+    if (results.numRuntimeErrorTestSuites > 0) {
+      console.warn(`${results.numRuntimeErrorTestSuites} test suites had runtime errors`);
+    }
+    
+    // Handle open handles
+    if (results.openHandles && results.openHandles.length > 0) {
+      console.warn(`${results.openHandles.length} open handles detected`);
+      
+      // Optionally force exit
+      if (globalConfig.forceExit) {
+        process.exit(results.success ? 0 : 1);
+      }
+    }
+    
+    return results;
+    
+  } catch (error) {
+    console.error("Test execution failed:", error);
+    
+    // Attempt recovery or cleanup
+    if (error.message.includes("worker")) {
+      console.log("Retrying with single worker...");
+      const fallbackConfig = { ...globalConfig, maxWorkers: 1, runInBand: true };
+      const fallbackScheduler = await createTestScheduler(fallbackConfig, schedulerContext);
+      return fallbackScheduler.scheduleTests(tests, new TestWatcher({ isWatchMode: false }));
+    }
+    
+    throw error;
+  }
+}
+
+class ErrorTrackingReporter {
+  private errors: Array<{ test: string; error: any }> = [];
+  
+  onTestResult(test: Test, testResult: TestResult) {
+    testResult.testResults.forEach(result => {
+      if (result.status === "failed") {
+        this.errors.push({
+          test: `${test.path} > ${result.title}`,
+          error: result.failureMessages
+        });
+      }
+    });
+  }
+  
+  onRunComplete() {
+    if (this.errors.length > 0) {
+      console.log("\n=== Test Failures Summary ===");
+      this.errors.forEach(({ test, error }) => {
+        console.log(`\n❌ ${test}`);
+        console.log(error.join("\n"));
+      });
+    }
+  }
+}
+```
+
+### Performance Optimization
+
+Optimize test scheduling for different scenarios and constraints.
+
+```typescript
+import { createTestScheduler } from "jest";
+
+interface SchedulingStrategy {
+  name: string;
+  configure: (config: Config.GlobalConfig) => Config.GlobalConfig;
+}
+

+  
+  const scheduler = await createTestScheduler(optimizedConfig, schedulerContext);
+  return scheduler.scheduleTests(
+    tests,
+    new TestWatcher({ isWatchMode: false })
+  );
+}
+
+// Auto-select strategy based on environment
+async function smartScheduling(tests: Array<Test>) {
+  const isCI = process.env.CI === "true";
+  const isDebug = process.env.DEBUG === "true";
+  const testCount = tests.length;
+

+    strategy = "fast";
+  } else {
+    strategy = "thorough";
+  }
+  
+  return scheduleWithStrategy(tests, strategy);
+}
+```
+
+Jest's test scheduling system provides complete control over test execution coordination, enabling optimized performance, comprehensive reporting, and reliable test execution across different environments and use cases.

+# Browser Support
+
+Browser-specific functionality for running Mocha tests in web browsers with DOM integration, process shims, and browser-optimized features.
+
+## Capabilities
+
+### Browser Setup
+
+Initialize Mocha for browser environments with configuration and DOM integration.
+
+```javascript { .api }
+/**
+ * Browser-specific mocha setup function
+ * @param options - Browser configuration options
+ * @returns {mocha} Global mocha instance
+ */
+mocha.setup(options);
+
+/**
+ * Browser setup options
+ */
+interface BrowserSetupOptions {
+  ui?: string;           // Interface: 'bdd', 'tdd', 'qunit', 'exports'
+  reporter?: string;     // Reporter name (defaults to 'html')
+  timeout?: number;      // Global timeout in milliseconds
+  slow?: number;         // Slow test threshold
+  grep?: string;         // Test filter pattern
+  fgrep?: string;        // Fixed string filter
+  invert?: boolean;      // Invert grep pattern
+  bail?: boolean;        // Bail on first failure
+  checkLeaks?: boolean;  // Check for global leaks
+  globals?: string[];    // Global variables to ignore
+  delay?: boolean;       // Delay test execution
+  noHighlighting?: boolean; // Disable syntax highlighting
+}
+```
+
+**Usage Examples:**
+
+```html
+<!DOCTYPE html>
+<html>
+<head>
+  <title>Mocha Tests</title>
+  <link rel="stylesheet" href="node_modules/mocha/mocha.css">
+</head>
+<body>
+  <div id="mocha"></div>
+  
+  <script src="node_modules/mocha/mocha.js"></script>
+  <script>
+    // Setup Mocha for browser
+    mocha.setup({
+      ui: 'bdd',
+      reporter: 'html',
+      timeout: 5000,
+      slow: 100
+    });
+  </script>
+  
+  <!-- Load test files -->
+  <script src="test/browser-tests.js"></script>
+  
+  <script>
+    // Run tests when page loads
+    mocha.run();
+  </script>
+</body>
+</html>
+```
+
+```javascript
+// String-based setup (shorthand for ui)
+mocha.setup('bdd');
+
+// Object-based setup with full options
+mocha.setup({
+  ui: 'tdd',
+  reporter: 'html',
+  timeout: 10000,
+  globals: ['MY_GLOBAL']
+});
+```
+
+### Browser Test Execution
+
+Execute tests in browser environment with DOM integration and result display.
+
+```javascript { .api }
+/**
+ * Run tests in browser environment
+ * @param callback - Optional completion callback
+ * @returns {Runner} Runner instance
+ */
+mocha.run(callback);
+
+/**
+ * Callback function signature
+ * @param failures - Number of failed tests
+ */
+type RunCallback = (failures: number) => void;
+```
+
+**Usage Examples:**
+
+```javascript
+// Basic execution
+mocha.run();
+
+// With completion callback
+mocha.run(function(failures) {
+  console.log('Tests completed');
+  console.log(`Failed tests: ${failures}`);
+  
+  // Report results to parent window or test runner
+  if (window.parent !== window) {
+    window.parent.postMessage({
+      type: 'test-results',
+      failures: failures
+    }, '*');
+  }
+});
+
+// Get runner instance for event handling
+const runner = mocha.run();
+runner.on('end', function() {
+  console.log('All tests finished');
+});
+```
+
+### Browser Error Handling
+
+Enhanced error handling for browser environments with assertion integration.
+
+```javascript { .api }
+/**
+ * Throw error directly into Mocha's error handling system
+ * Useful for integration with assertion libraries
+ * @param error - Error to throw
+ */
+mocha.throwError(error);
+```
+
+**Usage Example:**
+
+```javascript
+// Integration with assertion libraries
+function customAssert(condition, message) {
+  if (!condition) {
+    const error = new Error(message);
+    error.name = 'AssertionError';
+    mocha.throwError(error);
+  }
+}
+
+// Usage in tests
+it('should handle custom assertions', function() {
+  customAssert(2 + 2 === 4, 'Math should work');
+  customAssert(true === true, 'Truth should be true');
+});
+```
+
+### Process Shim
+
+Browser-compatible process object for Node.js compatibility.
+
+```javascript { .api }
+/**
+ * Browser process shim - limited process object for compatibility
+ */
+interface BrowserProcess {
+  /**
+   * Add event listener for uncaught exceptions
+   * @param event - Event name ('uncaughtException')
+   * @param handler - Error handler function
+   */
+  on(event: 'uncaughtException', handler: (error: Error) => void): void;
+  
+  /**
+   * Remove event listener
+   * @param event - Event name
+   * @param handler - Handler function to remove
+   */
+  removeListener(event: string, handler: Function): void;
+  
+  /**
+   * Get listener count for event
+   * @param event - Event name
+   * @returns {number} Number of listeners
+   */
+  listenerCount(event: string): number;
+  
+  /**
+   * Get all listeners for event
+   * @param event - Event name
+   * @returns {Function[]} Array of listener functions
+   */
+  listeners(event: string): Function[];
+  
+  /**
+   * Standard output stream (browser-stdout shim)
+   */
+  stdout: any;
+}
+
+/**
+ * Access browser process shim
+ */
+const process = Mocha.process;
+```
+
+### Global Functions Export
+
+Browser-specific global function exports for ES module compatibility.
+
+```javascript { .api }
+/**
+ * Global functions available in browser after setup
+ * These are automatically attached to window/global scope
+ */
+
+// BDD interface functions (when ui: 'bdd')
+function describe(title, fn);

+
+### Browser-Specific Features
+
+Features and optimizations specific to browser environments.
+
+```javascript { .api }
+/**
+ * High-performance timer override for browser
+ * Optimized immediate execution scheduling
+ */
+Mocha.Runner.immediately = function(callback) {
+  // Browser-optimized immediate execution
+};
+
+/**
+ * URL query parameter parsing for browser test configuration
+ * Automatically applied when mocha.run() is called
+ */
+interface URLQueryOptions {
+  grep?: string;      // Filter tests by pattern
+  fgrep?: string;     // Filter tests by fixed string
+  invert?: boolean;   // Invert filter pattern
+}
+
+// Example URL: test.html?grep=User&invert=true
+// Automatically applies grep: 'User', invert: true
+```
+
+### HTML Reporter Integration
+
+Browser-specific HTML reporter with DOM integration and syntax highlighting.
+
+```javascript { .api }
+/**
+ * HTML reporter automatically integrates with DOM
+ * Requires <div id="mocha"></div> element
+ */
+
+/**
+ * HTML reporter features
+ */
+interface HTMLReporterFeatures {
+  /**
+   * Automatic syntax highlighting for code blocks
+   * Controlled by noHighlighting option
+   */
+  syntaxHighlighting: boolean;
+  
+  /**
+   * Interactive test result filtering
+   */
+  interactiveFiltering: boolean;
+  
+  /**
+   * Collapsible test suites
+   */
+  collapsibleSuites: boolean;
+  
+  /**
+   * Real-time progress indication
+   */
+  progressIndicator: boolean;
+}
+
+/**
+ * HTML reporter DOM structure
+ */
+interface HTMLReporterDOM {
+  container: HTMLElement;      // #mocha container
+  stats: HTMLElement;          // Test statistics
+  tests: HTMLElement;          // Test results
+  progress: HTMLElement;       // Progress indicator
+}
+```
+
+### Browser Loading Patterns
+
+Different approaches for loading Mocha in browsers.
+
+```javascript { .api }
+/**
+ * Script tag loading (UMD build)
+ */
+// <script src="node_modules/mocha/mocha.js"></script>
+// Creates global Mocha and mocha objects
+
+/**
+ * ES module loading (with bundler)
+ */
+import { describe, it, before, after } from 'mocha';
+
+/**
+ * CommonJS loading (with bundler like Browserify)
+ */
+const { describe, it } = require('mocha');
+
+/**
+ * AMD loading (with RequireJS)
+ */
+define(['mocha'], function(mocha) {
+  mocha.setup('bdd');
+  return mocha;
+});
+```
+
+### Browser Compatibility
+
+Browser support and compatibility information.
+
+```javascript { .api }
+/**
+ * Supported browsers (as of Mocha 11.7.2)
+ */
+interface BrowserSupport {
+  chrome: '>=60';      // Chrome 60+
+  firefox: '>=55';     // Firefox 55+
+  safari: '>=10';      // Safari 10+
+  edge: '>=79';        // Chromium-based Edge
+  ie: false;           // Internet Explorer not supported
+}
+
+/**
+ * Required browser features
+ */
+interface RequiredFeatures {
+  es6: true;           // ES6/ES2015 support required
+  promises: true;      // Native Promise support
+  eventEmitter: true;  // EventEmitter pattern support
+  json: true;          // JSON parsing/stringifying
+  setTimeout: true;    // Timer functions
+  console: true;       // Console logging
+}
+```
+
+### Browser Test Organization
+
+Best practices and patterns for organizing browser tests.
+
+```javascript { .api }
+/**
+ * Recommended browser test structure
+ */
+
+// test/browser/setup.js
+mocha.setup({
+  ui: 'bdd',
+  reporter: 'html',
+  timeout: 5000
+});
+
+// test/browser/utils.js  
+function waitForElement(selector) {
+  return new Promise(resolve => {
+    const check = () => {
+      const el = document.querySelector(selector);
+      if (el) resolve(el);
+      else setTimeout(check, 10);
+    };
+    check();
+  });
+}
+
+// test/browser/dom-tests.js
+describe('DOM Tests', function() {
+  beforeEach(function() {
+    document.body.innerHTML = '<div id="app"></div>';
+  });
+  
+  afterEach(function() {
+    document.body.innerHTML = '';
+  });
+  
+  it('should create DOM elements', async function() {
+    const app = document.getElementById('app');
+    app.innerHTML = '<button>Click me</button>';
+    
+    const button = await waitForElement('button');
+    assert(button.textContent === 'Click me');
+  });
+});
+
+// test/browser/run.js
+mocha.run(function(failures) {
+  console.log(`Browser tests completed: ${failures} failures`);
+});

+Mocha supports multiple configuration file formats.
+
+```javascript { .api }
+/**
+ * Configuration file formats and locations
+ */
+
+// .mocharc.json - JSON configuration
+{
+  "ui": "bdd",
+  "reporter": "spec",

+  "slow": 100,
+  "recursive": true,
+  "require": ["test/setup.js"],
+  "grep": "User"
+}
+
+// .mocharc.yml - YAML configuration  
+ui: bdd

+require:
+  - test/setup.js
+grep: User
+
+// .mocharc.js - JavaScript configuration
+module.exports = {
+  ui: 'bdd',
+  reporter: 'spec',
+  timeout: 5000,
+  slow: 100,

+    "reporter": "spec",
+    "timeout": 5000,
+    "recursive": true
+  }
+}
+```
+
+### Configuration Options Interface
+
+Complete configuration options available programmatically and via config files.
+
+```javascript { .api }
+/**
+ * Complete Mocha configuration options

+  afterEach?: Function | Function[];  // Global afterEach hooks
+}
+```
+
+### File Watching
+
+Automatic test re-execution when files change.
+
+```bash { .api }
+# Basic file watching
+mocha --watch
+
+# Watch specific files
+mocha --watch --watch-files "src/**/*.js,test/**/*.js"
+
+# Ignore files when watching
+mocha --watch --watch-ignore "node_modules/**,dist/**"
+
+# Watch with grep pattern
+mocha --watch --grep "Unit"
+```
+
+```javascript { .api }
+/**
+ * Programmatic file watching
+ */
+const mocha = new Mocha({
+  watch: true,
+  watchFiles: ['src/**/*.js', 'test/**/*.js'],
+  watchIgnore: ['node_modules/**', 'dist/**']
+});
+```
+
+### Parallel Execution Configuration
+
+Configure parallel test execution for improved performance.
+
+```bash { .api }
+# Enable parallel execution
+mocha --parallel
+
+# Set number of workers
+mocha --parallel --jobs 4
+
+# Parallel with other options
+mocha --parallel --jobs 2 --timeout 10000 --reporter spec
+```
+
+```javascript { .api }
+/**
+ * Parallel execution options
+ */
+interface ParallelOptions {
+  parallel: boolean;           // Enable parallel execution
+  jobs?: number;              // Number of worker processes
+  timeout?: number;           // Worker timeout
+  workerTimeout?: number;     // Worker-specific timeout
+}
+
+const mocha = new Mocha({
+  parallel: true,
+  jobs: 4,
+  timeout: 10000
+});
+```
+
+### Module Loading and Requirements
+
+Load modules and setup files before tests.
+
+```bash { .api }
+# Require modules before tests
+mocha --require test/setup.js --require should
+
+# Multiple requires
+mocha --require babel-register --require test/helpers.js
+
+# Include files before test files
+mocha --file test/globals.js --file test/setup.js
+```
+
+```javascript { .api }
+/**
+ * Module loading configuration
+ */
+interface ModuleLoadingOptions {
+  require?: string[];          // Modules to require before tests
+  file?: string[];            // Files to include before test files
+  loader?: string;            // Custom loader for test files
+}
+
+// Example setup file (test/setup.js)
+const chai = require('chai');
+const sinon = require('sinon');
+
+// Global setup
+global.expect = chai.expect;
+global.sinon = sinon;
+
+// Configure chai
+chai.config.includeStack = true;
+chai.config.truncateThreshold = 0;
+```
+
+### Environment Variables
+
+Environment variables that affect Mocha behavior.
+
+```bash { .api }
+# Common environment variables
+MOCHA_COLORS=1               # Enable colors
+MOCHA_GREP="pattern"         # Set grep pattern
+MOCHA_TIMEOUT=5000          # Set timeout
+MOCHA_REPORTER=json         # Set reporter
+NODE_ENV=test               # Set Node environment
+DEBUG=mocha:*               # Enable debug output
+
+# Usage examples
+MOCHA_TIMEOUT=10000 mocha test/
+DEBUG=mocha:runner mocha --grep "slow tests"
+```
+
+### Configuration Precedence
+
+Order of configuration precedence (highest to lowest):
+
+```javascript { .api }
+/**
+ * Configuration precedence order
+ * 1. Command line arguments (highest)
+ * 2. Environment variables  
+ * 3. Configuration files (.mocharc.*)
+ * 4. package.json "mocha" field
+ * 5. Default values (lowest)
+ */
+
+// Example: timeout value resolution
+// 1. --timeout 3000 (CLI)
+// 2. MOCHA_TIMEOUT=4000 (env)
+// 3. { "timeout": 5000 } (.mocharc.json)
+// 4. { "mocha": { "timeout": 6000 } } (package.json)
+// 5. 2000 (default)
+// Result: 3000ms (CLI wins)
+```
+
+### Advanced CLI Usage
+
+Complex CLI usage patterns and examples.
+
+```bash { .api }
+# Complex test execution
+mocha test/unit/**/*.spec.js \
+  --require test/setup.js \
+  --require babel-register \
+  --grep "User" \
+  --reporter json \
+  --timeout 5000 \
+  --slow 100 \
+  --bail \
+  --check-leaks
+
+# Parallel execution with custom options
+mocha --parallel \
+  --jobs 4 \
+  --timeout 10000 \
+  --reporter spec \
+  --require test/setup.js \
+  "test/**/*.spec.js"
+
+# Watch mode with filtering
+mocha --watch \
+  --watch-files "src/**/*.js" \
+  --watch-ignore "dist/**" \
+  --grep "integration" \
+  --reporter min
+
+# Browser test preparation
+mocha --reporter json \
+  --timeout 30000 \
+  --slow 5000 \
+  test/browser/**/*.js > browser-test-results.json
+
+# Debug mode with inspector
+mocha --inspect-brk \
+  --timeout 0 \
+  --grep "specific test" \
+  test/debug.spec.js
+```
+
+### Legacy mocha.opts (Deprecated)
+
+Legacy configuration file format (now deprecated in favor of .mocharc files).
+
+```bash { .api }
+# test/mocha.opts (deprecated)
+--require test/setup.js
+--require should
+--reporter spec
+--ui bdd
+--timeout 5000
+--colors
+--recursive
+test/**/*.spec.js
+```
+
+### Configuration Validation
+
+Mocha validates configuration and provides helpful error messages.
+
+```javascript { .api }
+/**
+ * Configuration validation examples
+ */
+
+// Invalid reporter
+mocha --reporter nonexistent
+// Error: invalid reporter "nonexistent"
+
+// Invalid timeout
+mocha --timeout abc
+// Error: timeout must be a number
+
+// Conflicting options
+mocha --forbid-only test/with-only.js
+// Error: .only tests found but forbidden
+
+// Invalid parallel configuration  
+mocha --parallel --bail
+// Warning: --bail not supported in parallel mode

+   */
+  run(callback);
+  
+  /**
+   * Dispose of this Mocha instance
+   */
+  dispose();
+}
+```
+
+**Usage Example:**
+
+```javascript
+const Mocha = require('mocha');
+
+const mocha = new Mocha({
+  ui: 'bdd',
+  reporter: 'spec',
+  timeout: 5000,
+  slow: 100
+});
+
+// Add test files
+mocha.addFile('./test/unit/helpers.js');
+mocha.addFile('./test/unit/models.js');
+
+// Configure additional options
+mocha
+  .grep('User')
+  .bail(true)
+  .checkLeaks(true);
+
+// Run tests
+mocha.run(function(failures) {
+  console.log(`Tests completed with ${failures} failures`);
+  process.exitCode = failures ? 1 : 0;
+});
+```
+
+### Runner Class
+
+Test execution engine that manages the test lifecycle and emits events.
+
+```javascript { .api }
+/**
+ * Runner class - manages test execution
+ * Extends EventEmitter for test lifecycle events
+ */
+class Runner extends EventEmitter {
+  /**
+   * Run all tests
+   * @param callback - Completion callback
+   * @returns {Runner} this - for chaining
+   */
+  run(callback);
+  
+  /**
+   * Abort test execution
+   * @returns {Runner} this - for chaining
+   */  
+  abort();
+  
+  /**
+   * Set grep pattern for filtering tests
+   * @param pattern - String or RegExp pattern
+   * @returns {Runner} this - for chaining
+   */
+  grep(pattern);
+  
+  /**
+   * Get current test count statistics
+   * @returns {Object} Test count statistics
+   */
+  stats;
+  
+  /**
+   * Check if runner is running
+   * @returns {boolean} Whether runner is currently executing
+   */
+  isRunning();
+}
+```
+
+### Runner Events
+
+The Runner emits events throughout the test lifecycle that reporters use:
+
+```javascript { .api }
+// Test execution lifecycle events
+const EVENTS = {
+  EVENT_RUN_BEGIN: 'start',           // Test run starts
+  EVENT_RUN_END: 'end',               // Test run ends
+  EVENT_SUITE_BEGIN: 'suite',         // Suite starts
+  EVENT_SUITE_END: 'suite end',       // Suite ends  
+  EVENT_TEST_BEGIN: 'test',           // Individual test starts
+  EVENT_TEST_END: 'test end',         // Individual test ends
+  EVENT_TEST_PASS: 'pass',            // Test passes
+  EVENT_TEST_FAIL: 'fail',            // Test fails
+  EVENT_TEST_PENDING: 'pending',      // Test is pending/skipped
+  EVENT_HOOK_BEGIN: 'hook',           // Hook starts
+  EVENT_HOOK_END: 'hook end'          // Hook ends
+};
+```
+
+**Usage Example:**
+
+```javascript
+const runner = mocha.run();
+
+runner.on('start', function() {
+  console.log('Test run started');
+});
+
+runner.on('pass', function(test) {
+  console.log(`✓ ${test.title}`);
+});
+
+runner.on('fail', function(test, err) {
+  console.log(`✗ ${test.title}: ${err.message}`);
+});
+
+runner.on('end', function() {
+  console.log('Test run completed');
+});
+```
+
+### Parallel Execution
+
+Mocha supports parallel test execution for improved performance:
+
+```javascript { .api }
+/**
+ * Enable parallel execution
+ * @param options - Parallel execution options
+ */
+const mocha = new Mocha({
+  parallel: true,
+  jobs: 4  // Number of worker processes
+});
+
+/**
+ * Parallel execution configuration
+ */
+interface ParallelOptions {
+  parallel: boolean;     // Enable parallel execution
+  jobs?: number;         // Number of workers (default: CPU count - 1)
+  timeout?: number;      // Worker timeout
+}
+```
+
+### Asynchronous Test Support
+
+Mocha supports multiple patterns for asynchronous tests:
+
+```javascript { .api }
+/**
+ * Test function signatures for different async patterns
+ */
+
+// Promise-based tests
+function testFunction(): Promise<any>;
+
+// Callback-based tests  
+function testFunction(done: DoneCB): void;
+
+// Async/await tests
+async function testFunction(): Promise<any>;
+
+type DoneCB = (error?: any) => void;
+```
+
+**Usage Examples:**
+
+```javascript
+// Promise-based
+it('should handle promises', function() {
+  return new Promise((resolve) => {
+    setTimeout(resolve, 100);
+  });
+});
+
+// Callback-based
+it('should handle callbacks', function(done) {
+  setTimeout(() => {
+    done();
+  }, 100);
+});
+
+// Async/await
+it('should handle async/await', async function() {
+  await new Promise(resolve => setTimeout(resolve, 100));
+});
+```
+
+### Context and Test State
+
+Each test receives a context object with utilities:
+
+```javascript { .api }
+/**
+ * Test context object (this in test functions)
+ */
+interface Context {
+  test?: Test;           // Current test object
+  currentTest?: Test;    // Alias for test
+  timeout(ms?: number): number | Context;  // Set/get timeout
+  slow(ms?: number): number | Context;     // Set/get slow threshold
+  skip(): never;         // Skip current test
+  retries(count?: number): number | Context; // Set/get retry count
+}
+```
+
+**Usage Example:**
+
+```javascript
+it('should use context methods', function() {
+  this.timeout(10000);  // Set timeout for this test
+  this.slow(1000);      // Set slow threshold
+  
+  // Conditionally skip test
+  if (process.env.SKIP_SLOW) {
+    this.skip();
+  }
+  
+  // Retry on failure
+  this.retries(3);
+});
+```
+
+### Test File Loading
+
+Mocha provides methods for loading and managing test files:
+
+```javascript { .api }
+/**
+ * Load test files synchronously
+ */
+mocha.loadFiles();
+
+/**
+ * Load test files asynchronously  
+ * @returns {Promise<Mocha>} Promise resolving when files are loaded
+ */
+mocha.loadFilesAsync();
+
+/**
+ * Unload test files from require cache
+ */
+mocha.unloadFiles();
+
+/**
+ * Add files to be loaded
+ * @param filepath - Path to test file
+ */
+mocha.addFile(filepath);
+
+/**
+ * Get list of files to be loaded
+ * @returns {string[]} Array of file paths
+ */
+mocha.files;
+```

+# Mocha
+
+Mocha is a feature-rich JavaScript testing framework that runs on Node.js and in browsers. It provides flexible test organization with BDD/TDD interfaces, extensive reporting options, asynchronous testing support, and parallel execution capabilities for improved performance.
+
+## Package Information
+
+- **Package Name**: mocha
+- **Package Type**: npm  
+- **Language**: JavaScript
+- **Installation**: `npm install mocha`
+
+## Core Imports
+
+```javascript
+const { Mocha } = require('mocha');
+const mocha = require('mocha');
+```
+
+For ES modules:
+
+```javascript
+import Mocha from 'mocha';
+import { describe, it, before, after, beforeEach, afterEach } from 'mocha';
+```
+
+Browser (via script tag):
+
+```html
+<script src="node_modules/mocha/mocha.js"></script>
+<script>
+  mocha.setup('bdd');
+</script>
+```
+
+## Basic Usage
+
+```javascript
+const { describe, it } = require('mocha');
+const assert = require('assert');
+
+describe('Array', function() {
+  describe('#indexOf()', function() {
+    it('should return -1 when the value is not present', function() {
+      assert.equal([1, 2, 3].indexOf(4), -1);
+    });
+    
+    it('should return the correct index when value is present', function() {
+      assert.equal([1, 2, 3].indexOf(2), 1);
+    });
+  });
+});
+```
+
+## Architecture
+
+Mocha is built around several key components:
+
+- **Interfaces**: Different styles for writing tests (BDD, TDD, QUnit, Exports)
+- **Test Organization**: Hierarchical structure with suites and tests
+- **Execution Engine**: Runner class that manages test execution and events
+- **Reporting System**: Pluggable reporters for different output formats
+- **Hook System**: Before/after hooks for setup and teardown at various levels
+- **Configuration**: Flexible options system supporting files, CLI args, and programmatic setup
+
+## Capabilities
+
+### Test Organization and Interfaces
+
+Mocha supports multiple interfaces for organizing tests, with BDD being the default. Each interface provides different syntax styles for defining test suites and cases.
+
+```javascript { .api }
+// BDD Interface (default)
+function describe(title, fn);
+function it(title, fn);
+function before(fn);
+function after(fn); 
+function beforeEach(fn);
+function afterEach(fn);
+
+// TDD Interface
+function suite(title, fn);
+function test(title, fn);
+function setup(fn);
+function teardown(fn);
+function suiteSetup(fn);
+function suiteTeardown(fn);
+```
+
+[Test Organization and Interfaces](./interfaces.md)
+
+### Test Execution and Runner
+
+Core test execution functionality with lifecycle management, event emission, and parallel execution support.
+
+```javascript { .api }
+class Mocha {
+  constructor(options);
+  run(callback);
+  addFile(filepath);
+  reporter(name, options);
+  timeout(ms);
+  slow(ms);
+}
+
+class Runner extends EventEmitter {
+  run(callback);
+  abort();
+  grep(pattern);
+}
+```
+
+[Test Execution and Runner](./execution.md)
+
+### Reporters and Output
+
+Comprehensive reporting system with built-in reporters and support for custom reporters.
+
+```javascript { .api }
+class Base {
+  constructor(runner, options);
+  done(failures, callback);
+  epilogue();
+}
+```
+
+[Reporters and Output](./reporters.md)
+
+### Browser Support
+
+Browser-specific functionality and setup for running tests in browser environments.
+
+```javascript { .api }
+// Browser global functions
+mocha.setup(options);
+mocha.run(callback);
+mocha.throwError(error);
+```
+
+[Browser Support](./browser.md)
+

+# Test Organization and Interfaces
+
+Mocha supports multiple interfaces for organizing and writing tests. Each interface provides a different syntax style and mental model for structuring test suites and cases.
+
+## Capabilities
+
+### BDD Interface (Default)
+
+Behavior Driven Development interface using `describe` and `it` functions. This is the default interface and most commonly used.
+
+```javascript { .api }
+/**
+ * Define a test suite
+ * @param title - Suite title/description
+ * @param fn - Suite implementation function
+ */
+function describe(title, fn);
+
+/**
+ * Define a test case
+ * @param title - Test title/description  
+ * @param fn - Test implementation function
+ */
+function it(title, fn);
+
+/**
+ * Define aliases for describe and it
+ */
+function context(title, fn); // alias for describe
+function specify(title, fn); // alias for it
+
+/**
+ * Define hooks that run before/after suites and tests
+ */
+function before(fn); // runs once before all tests in suite
+function after(fn);  // runs once after all tests in suite
+function beforeEach(fn); // runs before each test
+function afterEach(fn);  // runs after each test
+
+/**
+ * Exclusive execution - only run marked tests/suites
+ */
+function describe.only(title, fn);
+function it.only(title, fn);
+function context.only(title, fn);
+function specify.only(title, fn);
+
+/**
+ * Skip tests/suites - do not execute
+ */
+function describe.skip(title, fn);
+function it.skip(title, fn);
+function context.skip(title, fn);
+function specify.skip(title, fn);
+
+/**
+ * Skip aliases using x prefix
+ */
+function xdescribe(title, fn); // alias for describe.skip
+function xit(title, fn);       // alias for it.skip
+function xcontext(title, fn);  // alias for context.skip
+function xspecify(title, fn);  // alias for specify.skip
+```
+
+**Usage Example:**
+
+```javascript
+const assert = require('assert');
+
+describe('Calculator', function() {
+  let calculator;
+  
+  before(function() {
+    // Setup before all tests
+    calculator = new Calculator();
+  });
+  
+  beforeEach(function() {
+    // Reset state before each test
+    calculator.reset();
+  });
+  
+  describe('#add()', function() {
+    it('should add two positive numbers', function() {
+      const result = calculator.add(2, 3);
+      assert.equal(result, 5);
+    });
+    
+    it('should handle negative numbers', function() {
+      const result = calculator.add(-1, 1);
+      assert.equal(result, 0);
+    });
+    
+    it.skip('should handle decimal numbers', function() {
+      // This test is skipped
+    });
+  });
+  
+  describe.only('#multiply()', function() {
+    // Only this suite will run when using .only
+    it('should multiply two numbers', function() {
+      const result = calculator.multiply(3, 4);
+      assert.equal(result, 12);
+    });
+  });
+});
+```
+
+### TDD Interface
+
+Test Driven Development interface using `suite` and `test` functions.
+
+```javascript { .api }
+/**
+ * Define a test suite (equivalent to describe)
+ * @param title - Suite title/description
+ * @param fn - Suite implementation function
+ */
+function suite(title, fn);
+
+/**
+ * Define a test case (equivalent to it)
+ * @param title - Test title/description
+ * @param fn - Test implementation function
+ */
+function test(title, fn);
+
+/**
+ * Define hooks for setup and teardown
+ */
+function setup(fn);        // equivalent to beforeEach
+function teardown(fn);     // equivalent to afterEach
+function suiteSetup(fn);   // equivalent to before
+function suiteTeardown(fn); // equivalent to after
+
+/**
+ * Exclusive execution modifiers
+ */
+function suite.only(title, fn);
+function test.only(title, fn);
+
+/**
+ * Skip modifiers
+ */
+function suite.skip(title, fn);
+function test.skip(title, fn);
+```
+
+**Usage Example:**
+
+```javascript
+const assert = require('assert');
+
+suite('Calculator TDD', function() {
+  let calculator;
+  
+  suiteSetup(function() {
+    calculator = new Calculator();
+  });
+  
+  setup(function() {
+    calculator.reset();
+  });
+  
+  suite('Addition', function() {
+    test('should add positive numbers', function() {
+      const result = calculator.add(2, 3);
+      assert.equal(result, 5);
+    });
+    
+    test('should add negative numbers', function() {
+      const result = calculator.add(-2, -3);
+      assert.equal(result, -5);
+    });
+  });
+  
+  teardown(function() {
+    // Cleanup after each test
+  });
+});
+```
+
+### QUnit Interface
+
+QUnit-style interface providing `suite` and `test` functions with QUnit-compatible hooks.
+
+```javascript { .api }
+/**
+ * Define a test suite
+ * @param title - Suite title/description
+ * @param fn - Suite implementation function
+ */
+function suite(title, fn);
+
+/**
+ * Define a test case
+ * @param title - Test title/description
+ * @param fn - Test implementation function
+ */
+function test(title, fn);
+
+/**
+ * Define hooks
+ */
+function before(fn);     // runs before all tests in suite
+function after(fn);      // runs after all tests in suite
+function beforeEach(fn); // runs before each test
+function afterEach(fn);  // runs after each test
+
+/**
+ * Exclusive and skip modifiers
+ */
+function suite.only(title, fn);
+function test.only(title, fn);
+function suite.skip(title, fn);
+function test.skip(title, fn);
+```
+
+### Exports Interface
+
+Node.js module.exports style interface where test structure is defined using object properties.
+
+```javascript { .api }
+/**
+ * Exports interface uses object properties to define test structure
+ * No global functions - tests are defined as object methods
+ */
+
+// Example structure:
+module.exports = {
+  'Calculator': {
+    'before': function() {
+      // Setup
+    },
+    
+    '#add()': {
+      'should add positive numbers': function() {
+        // Test implementation
+      },
+      
+      'should add negative numbers': function() {
+        // Test implementation
+      }
+    },
+    
+    '#multiply()': {
+      'should multiply numbers': function() {
+        // Test implementation  
+      }
+    },
+    
+    'after': function() {
+      // Teardown
+    }
+  }
+};
+```
+
+**Usage Example:**
+
+```javascript
+const assert = require('assert');
+const Calculator = require('./calculator');
+
+module.exports = {
+  'Calculator Tests': {
+    before: function() {
+      this.calculator = new Calculator();
+    },
+    
+    'Addition Tests': {
+      beforeEach: function() {
+        this.calculator.reset();
+      },
+      
+      'should add two positive numbers': function() {
+        const result = this.calculator.add(2, 3);

+      },
+      
+      'should handle zero': function() {
+        const result = this.calculator.add(5, 0);
+        assert.equal(result, 5);
+      }
+    },

+        const result = this.calculator.multiply(3, 4);
+        assert.equal(result, 12);
+      }
+    }
+  }
+};
+```
+
+### Interface Selection
+
+```javascript { .api }
+/**
+ * Set the interface for a Mocha instance or globally
+ * @param name - Interface name: 'bdd', 'tdd', 'qunit', 'exports'
+ */
+mocha.ui(name);
+
+// Available interfaces
+const interfaces = {
+  bdd: require('mocha/lib/interfaces/bdd'),
+  tdd: require('mocha/lib/interfaces/tdd'), 
+  qunit: require('mocha/lib/interfaces/qunit'),
+  exports: require('mocha/lib/interfaces/exports')
+};
+```
+
+### Global Function Aliases
+
+All interfaces provide these global function aliases for compatibility:
+
+```javascript { .api }
+// These functions delegate to the current interface
+function describe(title, fn);  // maps to current interface's suite function
+function it(title, fn);        // maps to current interface's test function
+function before(fn);           // maps to current interface's before hook
+function after(fn);            // maps to current interface's after hook
+function beforeEach(fn);       // maps to current interface's beforeEach hook
+function afterEach(fn);        // maps to current interface's afterEach hook
+
+// TDD aliases (always available)
+function suite(title, fn);     // alias for describe
+function test(title, fn);      // alias for it
+function setup(fn);            // alias for beforeEach
+function teardown(fn);         // alias for afterEach
+function suiteSetup(fn);       // alias for before
+function suiteTeardown(fn);    // alias for after
+
+// Skip aliases
+function xdescribe(title, fn); // alias for describe.skip
+function xit(title, fn);       // alias for it.skip
+
+// Programmatic execution
+function run();                // trigger test execution
+```
+
+### Interface Configuration
+
+Interfaces can be configured when creating a Mocha instance:
+
+```javascript
+const mocha = new Mocha({
+  ui: 'tdd',  // Use TDD interface
+  // other options...
+});
+
+// Or set programmatically
+mocha.ui('bdd');

+ * @param options - Reporter-specific options
+ */
+class Base {
+  constructor(runner, options);
+  
+  /**
+   * Called when test run completes
+   * @param failures - Number of failed tests
+   * @param callback - Completion callback
+   */
+  done(failures, callback);
+  
+  /**
+   * Output test run summary/epilogue
+   */
+  epilogue();
+  
+  /**
+   * Get test statistics
+   * @returns {Object} Statistics object
+   */
+  stats;
+}
+
+/**
+ * Statistics object structure
+ */
+interface Stats {
+  suites: number;      // Number of suites
+  tests: number;       // Total number of tests
+  passes: number;      // Number of passing tests
+  pending: number;     // Number of pending tests
+  failures: number;    // Number of failing tests

+});
+
+// Using reporter constructor
+const CustomReporter = require('./custom-reporter');
+mocha.reporter(CustomReporter);
+
+// Programmatically
+mocha.reporter('json').reporter('tap'); // Last one wins
+```
+
+### Custom Reporters
+
+Create custom reporters by extending the Base class:
+
+```javascript { .api }
+/**
+ * Custom reporter implementation
+ */
+class CustomReporter extends Base {
+  constructor(runner, options) {
+    super(runner, options);
+    
+    // Listen to runner events
+    runner.on('start', () => {
+      console.log('Tests starting...');
+    });
+    
+    runner.on('pass', (test) => {
+      console.log(`✓ ${test.fullTitle()}`);
+    });
+    
+    runner.on('fail', (test, err) => {
+      console.log(`✗ ${test.fullTitle()}: ${err.message}`);
+    });
+    
+    runner.on('end', () => {
+      this.epilogue();
+    });
+  }
+}
+```
+
+### Reporter Events and Data
+
+Reporters receive these events with associated data:
+
+```javascript { .api }
+/**
+ * Runner events available to reporters
+ */
+const events = [
+  'start',      // Test run begins
+  'end',        // Test run ends  
+  'suite',      // Suite begins
+  'suite end',  // Suite ends
+  'test',       // Test begins
+  'test end',   // Test ends
+  'pass',       // Test passes
+  'fail',       // Test fails
+  'pending',    // Test is pending
+  'hook',       // Hook begins
+  'hook end'    // Hook ends
+];
+
+/**
+ * Test object structure passed to reporter events
+ */
+interface Test {
+  title: string;           // Test title
+  fullTitle(): string;     // Full hierarchical title
+  duration: number;        // Test execution time
+  state: 'passed' | 'failed' | 'pending';
+  err?: Error;            // Error if test failed
+  parent: Suite;          // Parent suite
+  pending: boolean;       // Whether test is pending
+  timeout(): number;      // Test timeout value
+  slow(): number;         // Test slow threshold
+}
+
+/**
+ * Suite object structure
+ */
+interface Suite {
+  title: string;           // Suite title
+  fullTitle(): string;     // Full hierarchical title
+  parent?: Suite;         // Parent suite
+  tests: Test[];          // Child tests
+  suites: Suite[];        // Child suites
+  pending: boolean;       // Whether suite is pending
+  timeout(): number;      // Suite timeout value
+  slow(): number;         // Suite slow threshold
+}
+```
+
+### Reporter Utilities
+
+Base reporter provides utility methods:
+
+```javascript { .api }
+/**
+ * Utility methods available in Base reporter
+ */
+class Base {
+  /**
+   * Get color function for terminal output
+   * @param name - Color name
+   * @returns {Function} Color function
+   */
+  color(name);
+  
+  /**
+   * Generate cursor movement for terminal
+   * @returns {Object} Cursor utilities
+   */
+  cursor;
+  
+  /**
+   * Check if output supports color
+   * @returns {boolean} Whether colors are supported
+   */
+  useColors;
+  
+  /**
+   * Get window size for formatting
+   * @returns {Object} Window dimensions
+   */
+  window;
+  
+  /**
+   * Get symbols for different output types
+   * @returns {Object} Symbol definitions
+   */
+  symbols;
+}
+
+/**
+ * Available color names
+ */
+const colors = [
+  'pass',     // Green
+  'fail',     // Red  
+  'bright pass',  // Bright green
+  'bright fail',  // Bright red
+  'bright yellow', // Bright yellow
+  'pending',  // Cyan
+  'suite',    // Blue
+  'error title',   // Red background
+  'error message', // Red text
+  'error stack',   // Gray
+  'checkmark',     // Green
+  'fast',     // Gray
+  'medium',   // Yellow
+  'slow',     // Red
+  'green',    // Green
+  'light',    // Gray
+  'diff gutter',   // Gray
+  'diff added',    // Green
+  'diff removed'   // Red
+];
+```
+
+### Reporter Configuration Options
+
+Different reporters accept various configuration options:
+
+```javascript { .api }
+/**
+ * Common reporter options
+ */
+interface ReporterOptions {
+  output?: string;         // Output file path
+  reporterOptions?: any;   // Reporter-specific options
+}
+
+/**
+ * XUnit reporter specific options
+ */
+interface XUnitOptions {
+  output?: string;         // XML output file
+  suiteName?: string;      // Test suite name in XML
+}
+
+/**
+ * JSON reporter specific options  
+*/
+interface JSONOptions {
+  output?: string;         // JSON output file
+}
+
+/**
+ * HTML reporter specific options
+ */
+interface HTMLOptions {
+  inline?: boolean;        // Inline CSS/JS
+  timeout?: number;        // Test timeout
+}
+```
+
+**Configuration Examples:**
+
+```javascript
+// XUnit with file output
+mocha.reporter('xunit', {
+  reporterOptions: {
+    output: './test-results.xml',
+    suiteName: 'My Test Suite'
+  }
+});
+
+// JSON with custom formatting
+mocha.reporter('json', {
+  reporterOptions: {
+    output: './results.json'
+  }
+});
+
+// Multiple reporters (using third-party libraries)
+const MultiReporter = require('mocha-multi-reporters');
+mocha.reporter(MultiReporter, {
+  reporterOptions: {
+    configFile: './reporter-config.json'
+  }
+});
+```

+  languageVersion: ScriptTarget;
+  impliedNodeFormat?: ResolutionMode;
+  setExternalModuleIndicator?: (file: SourceFile) => void;
+  jsDocParsingMode?: JSDocParsingMode;
+}
+```
+

+```
+
+### Language Variant
+
+```typescript { .api }
+enum LanguageVariant {
+  Standard = 0,
+  JSX = 1
+}
+
+enum ScriptKind {
+  Unknown = 0,
+  JS = 1,
+  JSX = 2,
+  TS = 3,
+  TSX = 4,

+
+### JSDoc Parsing
+
+```typescript { .api }
+enum JSDocParsingMode {
+  ParseAll = 0,
+  ParseNone = 1,
+  ParseForTypeErrors = 2,
+  ParseForTypeInfo = 3
+}
+
+function parseIsolatedEntityName(text: string, languageVersion: ScriptTarget): EntityName | undefined;
+function parseJsonText(fileName: string, sourceText: string): JsonSourceFile;
+```
+
+### Pre-Processed File Info
+
+Get file dependencies without full parsing.
+
+```typescript { .api }
+function preProcessFile(
+  sourceText: string,
+  readImportFiles?: boolean,
+  detectJavaScriptImports?: boolean
+): PreProcessedFileInfo;
+
+interface PreProcessedFileInfo {
+  referencedFiles: FileReference[];
+  typeReferenceDirectives: FileReference[];
+  libReferenceDirectives: FileReference[];
+  importedFiles: FileReference[];
+  ambientExternalModules?: string[];
+  isLibFile: boolean;
+}
+
+interface FileReference extends TextRange {
+  fileName: string;
+  resolutionMode?: ResolutionMode;
+}
+```
+
+### Text Range
+
+```typescript { .api }
+interface TextRange {
+  pos: number;
+  end: number;
+}
+
+interface ReadonlyTextRange {
+  readonly pos: number;
+  readonly end: number;
+}
+
+interface TextSpan {
+  start: number;
+  length: number;
+}
+
+interface TextChangeRange {
+  span: TextSpan;
+  newLength: number;
+}
+
+function createTextSpan(start: number, length: number): TextSpan;
+function createTextSpanFromBounds(start: number, end: number): TextSpan;
+function createTextChangeRange(span: TextSpan, newLength: number): TextChangeRange;
+function collapseTextChangeRangesAcrossMultipleVersions(changes: readonly TextChangeRange[]): TextChangeRange;
+```
+
+### Comment Ranges
+
+```typescript { .api }
+function getLeadingCommentRanges(text: string, pos: number): CommentRange[] | undefined;
+function getTrailingCommentRanges(text: string, pos: number): CommentRange[] | undefined;
+function getShebang(text: string): string | undefined;
+function isIdentifierStart(ch: number, languageVersion: ScriptTarget | undefined): boolean;
+function isIdentifierPart(ch: number, languageVersion: ScriptTarget | undefined, identifierVariant?: LanguageVariant): boolean;
+
+interface CommentRange extends TextRange {
+  kind: CommentKind;
+  hasTrailingNewLine?: boolean;
+}
+
+enum CommentKind {
+  SingleLine = 2,
+  MultiLine = 3
+}
+```
+
+### Token Utilities
+
+```typescript { .api }
+function isKeyword(kind: SyntaxKind): boolean;
+function isModifier(kind: SyntaxKind): boolean;
+function isFutureReservedKeyword(kind: SyntaxKind): boolean;
+function isContextualKeyword(kind: SyntaxKind): boolean;
+function isStringANonContextualKeyword(name: string): boolean;
+function isStringAKeyword(name: string): boolean;
+function isIdentifierANonContextualKeyword(node: Identifier): boolean;
+function isTrivia(kind: SyntaxKind): boolean;
+function isPunctuation(kind: SyntaxKind): boolean;
+function couldStartTrivia(text: string, pos: number): boolean;
+function scanString(text: string, start: number, astral?: boolean): string | undefined;
+function getTokenText(kind: SyntaxKind): string | undefined;
+```
+
+## Usage Example
+
+Using the scanner to tokenize source code:
+
+```typescript
+import * as ts from 'typescript';
+
+const code = 'const x: number = 42;';
+const scanner = ts.createScanner(
+  ts.ScriptTarget.Latest,
+  false, // don't skip trivia
+  ts.LanguageVariant.Standard,
+  code
+);
+
+let token: ts.SyntaxKind;
+while ((token = scanner.scan()) !== ts.SyntaxKind.EndOfFileToken) {
+  const start = scanner.getTokenStart();
+  const end = scanner.getTokenEnd();
+  const text = scanner.getTokenText();
+  
+  console.log(
+    ts.SyntaxKind[token],
+    `"${text}"`,
+    `(${start}-${end})`
+  );
+}
+```
+
+Parsing source code:
+
+```typescript
+import * as ts from 'typescript';
+
+const code = `
+function greet(name: string): string {
+  return 'Hello, ' + name;
+}
+`;
+
+const sourceFile = ts.createSourceFile(
+  'example.ts',
+  code,
+  ts.ScriptTarget.Latest,
+  true // set parent nodes
+);
+
+console.log('File name:', sourceFile.fileName);
+console.log('Statements:', sourceFile.statements.length);
+console.log('Parse diagnostics:', sourceFile.parseDiagnostics.length);
+
+// Print line and character for position 0
+const lineChar = sourceFile.getLineAndCharacterOfPosition(0);
+console.log(`Position 0 is at line ${lineChar.line}, character ${lineChar.character}`);
+```

+# TypeScript Compiler API
+
+TypeScript v5.9.3 provides a comprehensive compiler API with 1,683+ public API members for programmatically analyzing, transforming, and emitting JavaScript code.
+
+## Quick Start
+
+### Installation and Import
+
+```typescript
+import * as ts from 'typescript';
+// or
+const ts = require('typescript');
+```
+
+### Essential Pattern
+
+```typescript { .api }
+import * as ts from 'typescript';
+
+// 1. Parse source code into AST
+const sourceFile = ts.createSourceFile(
+  'example.ts',
+  'const x: number = 42;',
+  ts.ScriptTarget.Latest,
+  true
+);
+
+// 2. Create program for type checking
+const program = ts.createProgram({
+  rootNames: ['example.ts'],
+  options: { target: ts.ScriptTarget.ES2020 }
+});
+
+// 3. Get type checker
+const checker = program.getTypeChecker();
+
+// 4. Traverse AST
+function visit(node: ts.Node) {
+  console.log(ts.SyntaxKind[node.kind]);
+  ts.forEachChild(node, visit);
+}
+visit(sourceFile);
+
+// 5. Emit JavaScript
+const emitResult = program.emit();
+```
+
+## Common Tasks
+
+### Task: Parse and Analyze Code
+
+**Goal**: Parse TypeScript source code and analyze its structure.
+
+**Pattern**:
+1. Use `createSourceFile()` to parse code into AST
+2. Use `createProgram()` for type checking
+3. Use `program.getTypeChecker()` for type analysis
+4. Traverse AST with `forEachChild()` or `visitNode()`
+
+**APIs**:
+- `createSourceFile()` - Parse source text into AST
+- `createProgram()` - Create compilation program
+- `program.getTypeChecker()` - Get type checker for semantic analysis
+- `forEachChild()` - Traverse AST nodes
+
+**See**: [Core Compilation APIs](./core/compilation.md) | [AST Nodes](./ast/nodes.md) | [Type System](./types/type-checker.md)
+
+### Task: Transform Code
+
+**Goal**: Modify TypeScript code programmatically.
+
+**Pattern**:
+1. Create transformer factory function
+2. Use `transform()` or integrate with `program.emit()` via `CustomTransformers`
+3. Use `TransformationContext.factory` to create/modify nodes
+4. Use `visitEachChild()` to traverse and transform
+
+**APIs**:
+- `transform()` - Apply transformers to source files
+- `TransformerFactory` - Create custom transformers
+- `TransformationContext.factory` - Node factory for transformations
+- `visitEachChild()` - Visit and transform child nodes
+
+**See**: [Transformation](./transformation/transformers.md) | [Node Factory](./ast/factory.md)
+
+### Task: Generate Code
+
+**Goal**: Programmatically generate TypeScript code.
+
+**Pattern**:
+1. Use `factory` constant to create AST nodes
+2. Build complete AST structure
+3. Use `Printer` to convert AST to source code
+4. Or use `program.emit()` to generate JavaScript
+
+**APIs**:
+- `factory` - Node factory (300+ methods)
+- `createPrinter()` - Create printer for AST to source conversion
+- `program.emit()` - Emit JavaScript output
+
+**See**: [Node Factory](./ast/factory.md) | [Utilities](./utilities/printer.md)
+
+### Task: Provide IDE Features
+
+**Goal**: Implement editor features like completions, diagnostics, refactorings.
+
+**Pattern**:
+1. Create `LanguageServiceHost` implementation
+2. Use `createLanguageService()` to create service
+3. Call methods like `getCompletionsAtPosition()`, `getQuickInfoAtPosition()`
+4. Update host when files change
+
+**APIs**:
+- `createLanguageService()` - Create language service
+- `LanguageService` - 100+ methods for IDE features
+- `LanguageServiceHost` - Host interface for file operations
+
+**See**: [Language Service](./language-service/api.md)
+
+### Task: Resolve Modules
+
+**Goal**: Resolve module imports and type references.
+
+**Pattern**:
+1. Use `resolveModuleName()` for module resolution
+2. Use `resolveTypeReferenceDirective()` for type references
+3. Implement `ModuleResolutionHost` for file system operations
+4. Use `ModuleResolutionCache` for performance
+
+**APIs**:
+- `resolveModuleName()` - Resolve module imports
+- `resolveTypeReferenceDirective()` - Resolve type references
+- `ModuleResolutionHost` - File system interface
+
+**See**: [Module Resolution](./core/module-resolution.md)
+
+### Task: Build Projects
+
+**Goal**: Build TypeScript projects with incremental compilation.
+
+**Pattern**:
+1. Use `createSolutionBuilder()` for multi-project builds
+2. Configure project references in tsconfig.json
+3. Use incremental compilation with `BuilderProgram`
+4. Handle diagnostics and emit results
+
+**APIs**:
+- `createSolutionBuilder()` - Multi-project builds
+- `createIncrementalProgram()` - Incremental compilation
+- `BuilderProgram` - Incremental program interface
+
+**See**: [Solution Builder](./core/solution-builder.md) | [Core Compilation](./core/compilation.md)
+
+## Core Architecture
+
+TypeScript's compiler API consists of these major subsystems:
+
+1. **Parser & Scanner**: Lexical analysis and AST construction
+2. **Binder**: Symbol creation and scope analysis
+3. **Type Checker**: Type inference, checking, and semantic analysis
+4. **Transformer**: AST transformation pipeline
+5. **Emitter**: JavaScript and declaration file generation
+6. **Language Service**: Editor integration (completions, diagnostics, refactorings)
+7. **Module Resolution**: Resolving imports and type references
+8. **Server Protocol**: TSServer communication
