Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~10 minutes Change: Bug fix Merge Risk: ⚪ Minimal · up to The change selects Nitro’s configured entry when its facade is available and retains the existing fallback otherwise. The described regression tests cover competing entries, and no concrete merge-blocking risk remains. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new selection uses the configured server entry rather than output order, while retaining the previous fallback. The reviewed change does not establish a new exposed endpoint or attack path, but the full downstream use of the metadata has not been verified.

In `@src/build/info.ts`:
- Line 142: Update the facade matching in writeBuildInfo to compare against
Nitro’s bundler-resolved input ID instead of accepting any facade with the same
path stem. Add a regression case with both server.ts and server.js, verifying
that serverEntry points to the resolved server.ts entry.

- match facade ids by resolved path only, drop stem fallback - warn when no output chunk matches the nitro entry - move BUILD_EXTENSIONS to a standalone module to keep info.ts light - generate unit test fixtures in a temp dir

When no entry facade matches, metadata selection keeps its prior first-entry behavior. The Module Federation repro emits the matching Nitro facade ID.
