 ### Accessibility/touch decisions
 
 Open-page actions remain explicit, large existing Button targets; unresolved-page save is visibly disabled with a plain-language resolution message. Proxy authorization never exposes PocketBase admin credentials to the browser.

+
+### Fixes
+
+- Added server-safe `split-review-model.ts` for payload cleanup, note-group rehydration, dismissed-page rehydration, and orphan-page derivation. The Server Component and Client Component now import this module directly; no Server Component imports the `use client` module.
+- `deriveOpenPages` preserves and deduplicates persisted `open_pages`, then adds every uncovered page as an actionable `not assigned` entry, including the no-existing-open-pages case.
+- Added focused coverage for the pure module boundary, missing page 4 derivation, persisted-entry deduplication, and dismissed preservation.
+
+### Build note
+
+`npm run build` emitted the repository's existing metadataBase warning but completed successfully; generated icon/OG assets were unchanged in git.
