The vector clocks in the server were never reached: no client sent one,
so the branch was dead and every write was a blind overwrite. Not "the
newer edit wins" — "the request that arrives last wins", which is worse:
a phone that was offline all day buries the laptop's newer work simply by
reconnecting late.
Each write now carries baseUpdatedAt, the revision it was written on top
of. If the note has moved on since, the incoming edit still wins — a
rejection would throw away what was just typed — but the state it
replaces is kept as a version marked "conflict", so both exist and the
history is where you choose. Clocks could have told a real conflict from
a device catching up, but that precision only pays off with a merge
interface, and this reuses the version history already built.
adoptRevision() stores the revision the server reports back, or the
second save in a row would be flagged as conflicting with the first.
Also removed, as agreed:
- POST /api/notes/pdf — accepted PDFs that nothing could ever read back,
with no retrieval route and no viewer. The readme advertised "PDF
Import & Annotation"; that claim is gone too.
- POST /api/sync — a batch endpoint the client never called.
- the tags column — notebooks, starring and search already cover it.
Columns on existing databases are left in place. Dropping them buys
nothing and is not worth touching a live database for.
Tables now have a right-click menu (editor/tableMenu.js) for rows,
columns, header and merging. It needs stopPropagation: without it the
same event reaches window, where the menu that is mounting reads it as a
click elsewhere and closes instantly — the reason the other context menus
in App.jsx already do this.
92 browser checks across seven suites, 125 unit tests.

The app is meant to run in daily private use now, so this pass was mostly
about the ways it could quietly lose data.
Reliability and security:
- the server no longer invents a JWT_SECRET or ENCRYPTION_KEY when one is
missing; it refuses to start. The old fallback silently made every stored
note unreadable after a restart.
- notes are encrypted with AES-256-GCM (v2:); existing CBC bodies still read.
- login is rate limited and compares against a dummy hash when the user does
not exist, so timing does not reveal who is registered.
- a server response issued before a local save is never adopted. This had
already eaten drawing strokes and note links; sync.hasPendingWrites() now
guards every path that takes a body from the server.
Editor and features:
- TipTap replaces the contenteditable editor: tables, task lists, and links
to other notes and notebooks, with a backlinks bar on the target.
- content format v2 ({v:2,doc}); v1 {html,tasks} bodies migrate on open.
- version history: the state before each write is snapshotted, coalesced
into 5-minute windows, 50 versions or 90 days per note.
- full-text search runs in the client, because the server cannot read
encrypted bodies and a server index would defeat the encryption.
- image attachments are stored by SHA-256 and deduplicated; the client
fetches them authenticated and caches the blob, so they work offline.
- drawings are vector strokes in a fixed 1200x1600 page space and now look
the same on every screen (0.0-0.2% deviation across four widths).
- login is by username; existing email accounts migrate automatically.
Operations:
- data lives on host bind mounts, not Docker volumes, so Proxmox Backup
covers it. Back up .env with it — without ENCRYPTION_KEY the dump is
unreadable.
Structure:
- NoteApp.jsx is gone. App.jsx now holds only where the user is; note data,
search, layout, history and drag each live behind a hook, and the four
panes are stateless.
- the whole data layer is TypeScript, with 81 unit tests concentrated on
the places that have actually broken.
- fixed along the way: the browser back button had a dead press, because
restoring a history entry pushed a duplicate one.
