The mobile React tests previously ran application hooks without Expo’s React Compiler. That made a focus-effect test demand manual memoization even though the Release compiler already stabilized the callback.

Compile mobile application modules in the React test project with the checked-in Expo Babel configuration and iOS Release compiler flags. Keep test fixtures uncompiled. The Node test runner uses inline Babel helpers instead of Metro runtime imports.

Remove the proposed manual useCallback from the review guide and pass existing refresh functions directly to focus effects. The behavioral tests now verify focus refresh, running-guide polling, and cleanup with compiler output. No production refresh-loop or performance improvement is claimed.

Validation: all 131 tests in the mobile React project pass; check:changed passes. Native views remain mocked in this project, so this is not device verification. The small task-cache test service-provision cleanup is retained to satisfy current CI lint.

Implemented and reviewed with GPT-6.1-sol through the Codex harness.

Approvability

Verdict: Approved at 0a43bc0

Macroscope's review found this PR approvable — This PR adds release-compiler coverage for mobile React tests and makes a small, localized stabilization of existing pull-request focus refresh effects. The remaining changes are test-only cleanup and focused lifecycle tests, with no product-default or static-analysis suppression changes.

Walkthrough

Pull-request screens now pass refreshDetail directly to focus effects. The mobile test setup adds Babel transformation support and tests for review-guide refresh and polling behavior. A task-cache cleanup test now provides its cache service directly.

Changes: Pull-request focus refresh

Layer / File(s)	Summary
Pass refresh callbacks directly to focus effects apps/mobile/src/features/pull-requests/PullRequestInlineCommentScreen.tsx, apps/mobile/src/features/pull-requests/PullRequestReviewSheet.tsx, apps/mobile/src/features/pull-requests/PullRequestRouteScreen.tsx	The inline-comment screen, review sheet, overview screen, and file-diff screen pass refreshDetail directly to useFocusEffect.
Configure and test review-guide behavior apps/mobile/vite.config.ts, apps/mobile/src/features/pull-requests/guide/useReviewGuide.test.tsx	Vite transforms matching TypeScript source files with the local Babel configuration. Tests cover focus refreshes, polling, target changes, and timer cleanup.

Task-cache test service setup

Layer / File(s)	Summary
Provide the cache service in the cleanup test infra/task-cache/src/Cleanup.test.ts	The test provides the same cache handlers with Effect.provideService instead of constructing a Layer.succeed layer.

`src` URL with `fileURLToPath` and normalize the resulting filesystem path
