Several unsent text changes of one block were applied one by one to the
local view, numbering local versions ahead of the server, which folds them
into one change (formBatch). The focused field kept the inflated version as
base, so the next edit after a sync conflicted with the user's own text.
The local view now applies pending ops as they will be sent.

eslint.config.js with the recommended JS/TypeScript rules and the React
hooks rules; npm run lint runs ESLint and is part of the image build.
Errors fail the build, the 24 exhaustive-deps findings stay warnings.
It found two real bugs: TaskDetailModal and ManageColumnsModal called
their hooks after 'if (!isOpen) return null', so the hook count changed
whenever the dialog opened or closed. Both are now a thin wrapper plus a
content component. Also removes unused imports and dead code (old task
list share handlers, an unused realtime status, an unused rollup).

- Background job at start and every 6 h: log entries older than 30 days
(private notes: 7) are removed, documents.log_floor marks the boundary;
clients behind it get resync and keep their queued changes
- Deleted blocks are purged 30 days after deleted_at via a "purge" log
effect, so open editors drop them without reloading; a tombstone stays
while a deleted child still points to it
- Text for a purged block becomes a new block at the end; inserts under a
purged parent go to the top level (server and browser model)
- doc_op_results kept for 90 days; expired lease/session maps are swept
- Tests: storage, API, engine resync, simulation with compactions

Phase 4 of the collaboration plan:
- The sync engine listens for DOC_SEQ in the note's realtime room and syncs
right away. Without WebSocket/SSE it long-polls /docs/{id}/changes (25 s);
after three failures it falls back to polling every 3 s and retries long
polling when the browser comes back online.
- With push or long polling the engine only syncs every 7 s while holding
leases (renewal), otherwise every 30 s as a safety net. Focusing a block
announces its lease immediately (otherwise it could take up to 30 s).
- Realtime connection: SSE counts as connected only after its first event;
a stream that stays silent for 5 s (buffering proxy) switches SSE off for
the tab. App-level PING/PONG detects WebSockets that are accepted but
forward nothing and switches to SSE after 35 s.
- The editor shows the active channel for shared notes.
- Tests: engine channel tests (push, heartbeat, lease on focus, long
polling, interval fallback, switching), realtime fallback tests with fake
WebSocket/EventSource, Go tests for PONG and DOC_SEQ delivery, and
e2e/channels.e2e.mjs measuring latency behind six simulated proxy setups
(0.2-0.3 s on all live channels, ~3 s with plain polling).

Phase 3 of the collaboration plan:
- Blocks held by someone else show a lock with the name and are read-only;
Enter in such a block adds a new block below. Delete, merge, indent and
drag are not started when a involved block (or one in its branch) is
locked; a short notice explains why (fixes FLAW-25).
- Presence: the editor header lists who else has the note open.
- Conflict copies are highlighted ("Konflikt – Version von …") with
Übernehmen (replaces the original or the title) and Verwerfen. Both check
the locks of the original and of the copy first.
- Undo/redo of own changes (Ctrl/Cmd+Z, Ctrl+Shift+Z, Ctrl+Y, beforeinput
history events): typing is grouped per block until a 1 s pause, up to 200
steps per tab; a step is skipped with a notice if someone else changed or
holds the block meanwhile. New clearConflict props patch on the server.
- New blocks get focus synchronously on mount (fixes FLAW-26).
- Fix: after reopening a note from local storage the engine polled every
30 s instead of 3 s until the next change, because the delay was decided
before the first response told it the note is shared.
- Tests: undo/conflict engine tests, lock/undo/conflict UI tests and
e2e/lock.e2e.mjs (two browsers); all three browser tests pass against a
freshly built image.

Phase 2 of the collaboration plan:
- frontend/src/lib/docSync: TypeScript port of the block tree, operations,
effects and order keys (kept identical to Go via shared test vectors),
diff from the editor's flat list to operations, IndexedDB persistence,
HTTP transport and DocSyncEngine (one request in flight, idempotent
resends, backoff, 3 s/30 s polling, keepalive flush and leave on exit,
block leases for focus, 20 s grace and new blocks).
- Text changes carry the version the user saw when typing (first change
wins when coalescing; a stale focused field keeps its old base), so a
concurrent edit becomes a conflict copy instead of a silent overwrite.
- DocumentEditor uses the engine instead of the 800 ms whole-document PUT;
editors (not only owners) can edit, remote changes appear live.
- Server: task IDs of linked blocks are delivered again, linked tasks follow
ticked/deleted blocks after sync, note tags are derived, title changes
notify other users; block IDs already used in another note are renamed
(starter content with fixed IDs was empty for every further user).
- Fix: unlinking tasks from blocks wrote to non-existent columns and never
worked (error was swallowed).
- Tests: Go/TS order key vectors, diff round trips, engine races (lost
responses, offline + reload, edits arriving between typing and sending,
stale focused field, duplicate first block), plus a Playwright test with
two browsers against the real image (e2e/run.sh).
