## Summary - If the WASM build fails (e.g. GitHub CDN outage for tree-sitter-cli or wasi-sdk) but a cached `.wasm` file already exists, warn instead of crashing `pnpm install` - Only hard-fail when no cached WASM exists at all This prevents transient CDN outages from blocking deploys when the WASM artifacts are already cached. ## Test plan - [ ] CI passes on this PR (validates the postinstall script doesn't crash) - [ ] Verify deploy workflow can proceed when WASM cache hits
