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).

Phase 1 of the collaboration plan (server side):
- internal/collab: block tree with parent IDs and fractional order keys,
operations with conflict rules (version check, block leases, conflict
copies instead of lost text, restore on late edits, cycle checks),
in-memory leases/sessions and long-poll notifier.
- Storage: per-note lock + transaction, append-only effect log (doc_ops),
idempotent results per opId (doc_op_results), snapshot, log paging,
central DocRole. Old flat block data is converted to the tree.
- The existing whole-document save (PUT/PATCH) runs as an adapter through
the same engine, so the current editor keeps working and writes to the log.
- API: GET /docs/{id}/snapshot, POST /docs/{id}/sync, GET /docs/{id}/changes
(long poll), POST /docs/{id}/leave; DOC_SEQ poke for WebSocket/SSE rooms.
- Backend accepts editor (write) shares for notes and folders; the forced
read-only migration is gone. The share dialog still offers read only.
- Tests: conflict matrix, order keys, leases, storage adapter round trip,
idempotency, API protocol incl. long poll, and a randomized simulation
(4 clients, lost/duplicated requests and responses, offline phases,
lease expiry) checking convergence, no lost text and exactly-once results.

Phase 0 of the collaboration plan:
- Remove BroadcastToAll; task, task list and workspace folder events now
only reach users who can see the resource. Task list events carry only
the list ID, clients reload with their own permissions.
- Reject unauthenticated WebSocket/SSE connections (401). Every room join
(URL room, JOIN_ROOM, SSE rooms) is checked via a room authorizer;
/events/rooms requires login and only accepts the caller's own sseId.
- Reorder rejects tasks the caller cannot access or edit (IDOR).
- Lift the server WriteTimeout for SSE streams so they are not cut after 30s.
- Fix folder share removal sending DOC_DELETED to the share ID.
- Tests for all of the above; docs and flaw list updated.

Server-authoritative operation log with per-block versions and 20s
block leases, conflict copies instead of data loss, IndexedDB queue
for offline use, HTTP-based sync with WebSocket/SSE/long-poll wakeups,
unified note/folder permissions, and per-user undo.

- Add vitest, jsdom and Testing Library as dev dependencies,
replace the placeholder test:run script with vitest run.
- Add outliner tests for Backspace merging and caret placement on click.
- Run the frontend tests in the Dockerfile before the Vite build.
- Update docs (README, architecture, FLAW-19).

- Clicking into a bullet places the caret where the mouse was, mapped
from the rendered markdown layer back to the raw text, instead of
always jumping to the end.
- Remove the grey background on focused and hovered rows and on the
bullet handle.
- Collapse/expand chevrons are only shown while hovering the row.

The merge only applied to a fixed list of block types, so legacy blocks
without a type were ignored, and blocks with children were rejected.
Now only code/divider/table/progress are excluded and children move up
under the previous block. The focused bullet dot is also neutral now.

- Backspace at the start of a non-empty bullet appends its text to the
previous visible bullet (skipped for blocks with children and for
code/divider/table/progress blocks).
- Hashtags are rendered inline as clickable chips instead of a badge row
below the text, so lines no longer grow taller.
- Targeted/highlighted bullets use a neutral background instead of accent.

Remove outdated claims (CRDT, DocRooms, presence, .md files on disk) and
document the actual architecture, API, permissions and known flaws.

Task list shares now carry a permission (editor/viewer). The server rejects
writes from viewers with 403, and the UI hides or disables edit controls
for read-only lists.
