Phase 1 遺留的跨裝置同步 bug 一直沒查出根因，使用者決定放棄整條雲端同步路線。 移除 Clerk 登入、Client 層 apiClient、四個 service 的 remote/merge/pushNow/ restoreForBook 與 tombstone 機制、後端 API route、Prisma schema/資料庫、 TanStack Query，四個 service 只留本機 CRUD。renderer/mobile 後續只做本機儲存版 的 Client/Service/Hook 分層，不再規劃任何登入/跨裝置同步。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughpwa-next now uses local storage only. The change removes authentication, cloud synchronization, API routes, Prisma, database dependencies, and remote service methods. Reader hooks and application pages use local persistence. Documentation reflects the new architecture and privacy model. ChangesLocal-only pwa-next
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The switch to local-only storage still has bounded correctness and data-loss risks: malformed saved annotations may prevent books from opening, external fonts may not be cleaned up, and rapid bookmark actions or storage failures may lose local changes. These issues should be fixed or explicitly accepted before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)
