## Summary - `napi_typeof` was returning `napi_object` for `AsyncContextFrame` values, which are internally callable JSObjects - Native addons that check callback types (e.g. encore.dev's runtime) would fail with `expect Function, got: Object` and panic - Added a `jsDynamicCast<AsyncContextFrame*>` check before the final `napi_object` fallback to correctly report these values as `napi_function` Closes #25933 ## Test plan - [x] Verify encore.dev + supertokens reproduction from the issue no longer panics - [ ] Existing napi tests continue to pass Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude <noreply@anthropic.com>
