+## 2026-06-27 (Lockfile Sync)
+**Change:** build(deps): remove platform-specific optionalDependencies and sync package-lock.json
+
+**Details/Why:**
+Removed superfluous top-level `@emnapi/core` and `@emnapi/runtime` from `optionalDependencies` in `package.json`. Having platform-specific WebAssembly fallbacks explicitly listed in root `package.json` caused macOS lockfile updates (`npm install`) to prune their Linux/Windows peer entries, which triggered `npm ci` failures (`EUSAGE: missing @emnapi/core from lock file`) on Linux CI runners. Ran `npm install` to regenerate a cross-platform lockfile.
+
+**Files changed:** `package.json`, `package-lock.json`, `AUDIT_LOG.md`.
