Claude Opus 4.8	fa7ae033b5	Add permission-revocation handling for live and offline sessions (#39) ... Revoking write access must terminate live sessions and let a user with pending offline edits export them rather than lose them silently. Backend (generic, reused by M5 grants #53): - packages/shared: POND_ACCESS_CHANGED_CHANNEL, the LISTEN/NOTIFY channel shared by api and collab. - api: PondAccessNotifier emits pg_notify(pond_access_changed, pondId) on a permission-relevant change; the single generic seam for revocation. Wired into pond soft-delete as the interim trigger (see==modify until #53). - collab: a dedicated-connection LISTEN listener (LISTEN is connection- bound, not pooled) that, on a notification, closes every open connection to the pond's open pages. Clients then reconnect and the api re-issues a token reflecting current access (downgrade to ro, or 403/404). Reconnects and re-LISTENs if its connection drops. Frontend: - use-collab-provider: a refused token (403/404) on (re)connect sets accessRevoked and stops the reconnect loop; exposes discardLocal. - AccessRevokedDialog: keeps local content visible and offers Markdown copy/download (derived from the live editor doc, so offline edits are included) and an explicit discard that clears IndexedDB. de+en strings. Tests: collab DB-backed integration test proves a direct NOTIFY closes a live session within seconds (AC1) and leaves unrelated ponds untouched; listener unit tests; api test asserts soft-delete fires the notifier; web test for the export Markdown derivation.

Claude Opus 4.8	af81b50fa6	Add offline editing: local persistence, PWA shell, offline resolution (#38) ... Editing continues without a connection and merges conflict-free on reconnect (ADR 0003, realtime-collaboration.md §Offline). - y-indexeddb mirrors every opened page's Y.Doc to IndexedDB, sharing the document with the collab provider. The local copy is discarded when the page is left after a successful server sync (bounding IndexedDB growth) and kept otherwise so offline edits survive to the next visit. - vite-plugin-pwa service worker precaches the app shell (build assets only) with a navigation fallback; `/api` and `/collab` are denylisted and there is no runtime caching, so API responses are never cached or poisoned. - Offline page resolution WITHOUT caching API responses: the app itself persists the small metadata it needs to reopen a visited page (page/pond ids + slugs, bounded LRU in localStorage) and the last signed-in user, so after an offline tab reload the app stays signed in, resolves the page, and restores its content from IndexedDB. Both are revalidated when the network returns (a 401 clears the cached user). - Local-only UI: a banner when there are edits held only on this device (provider `onUnsyncedChanges`), de + en. Tests: `page-cache` unit test (remember/recall + bounded eviction); a new `offline` e2e pack (validated locally against the full stack and wired into CI): edit, reload while offline (shell from the SW, content from IndexedDB), assert an API call fails offline (no SW API caching), then reconnect and a second client converges. The e2e static server serves `.webmanifest`. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PGdhRiwU1WRL4XxJfZYipY	2026-07-08 22:08:55 +02:00
Claude Opus 4.8	7d04c0b594	Switch the editor to live collaboration (#36) ... The editor now edits over the collaboration server instead of REST — the moment Dorfteich becomes collaborative (ADR 0003, realtime-collaboration.md). Web: - New `useCollabProvider` hook binds a page's Y.Doc to a HocuspocusProvider. The document loads and persists through the collab server (#35); there is no REST autosave and no REST seed (a REST seed would fork the doc lineage and duplicate content). The collab token is fetched lazily on every (re)connect via an async token function, so an expired token is replaced transparently and a permission change takes effect on the next reconnect. - Connection-state UI replaces the save indicator: connecting / connected ("Live") / reconnecting / offline, driven by provider status + navigator online state. Read-only (`ro`) tokens make the editor non-editable with a reason; an oversize-document stateless error (#35) surfaces a banner. - Removed `use-page-autosave.ts` and `yjs-base64.ts` (no longer used). API: - `PUT /pages/:id/state` is retired and returns 410 `rest_state_write_retired` (the criterion deferred here from #35). Collab is the sole writer of page state; the read paths remain. Removed the now-dead `saveState` service. e2e / CI: - The e2e static server proxies the `/collab` WebSocket upgrade (mirrors Caddy); vite dev gains a `/collab` ws proxy. The auth-e2e CI job starts the collab server and runs a new collab pack. - New `collab.spec.ts`: two browsers converge on one page (the milestone headline), and offline edits continue locally and sync on reconnect. The read-only live assertion is a `test.fixme` until real read-only grants exist — under interim access seeing and modifying coincide, so no `ro` token is issued yet (that arrives with #53). Reworked the api/trash tests and the content editor-basics test off the retired REST write path.
