Ticking a task off never removed its row. The optimistic update ran, the
request went out, the server answered 200 — and the view did not move.
The same applied to a change arriving over the websocket, which is how
somebody else's edit was supposed to show up. It had never worked.
The common factor was tasks[i] = value. push and whole-array assignment
both reached the views; index assignment did not. Rather than depend on
which mutations the reactivity happens to see through, every write now
goes through app.replace() or app.upsert(), which build a new array. The
lists are at most a few hundred rows and the copy is not worth a moment's
thought next to the class of bug it removes.
upsert exists because the same task arrives twice: once as the response
to the request that created it, and once over the socket, which publishes
to the whole project including whoever did it. Either can land first, and
appending both puts two rows with one id into a keyed {#each} — not a
duplicated row but a thrown error that stops the view rendering.
complete, reopen and update were three copies of the same twenty lines;
they are now one private helper.

The SvelteKit PWA. Not written yet — this directory holds its place so the Docker build has something to copy, and so the frontend stage can tell "not built yet" apart from "the build failed".
The Dockerfile builds this directory when it finds a package.json here, and
otherwise emits a placeholder page. So adding the real app is exactly: put a
SvelteKit project in this directory whose npm run build produces build/.
What it needs to be
- SvelteKit,
adapter-static, output inbuild/. The Go binary embeds that directory at compile time and serves it, falling back toindex.htmlso client-side routes survive a reload. - A PWA: installable, offline reading of already-cached lists, swipe gestures for complete and schedule.
- Nordic minimalism. Dark by default, light available. One accent colour, everything else neutral. Runic mark for Verdande.
- Optimistic on every local action. No spinner ever appears for something the browser could already know the answer to.
Talking to the backend
Same origin — the Go binary serves both. /api/v1 for REST, /api/v1/ws for the
live sync. Session cookie is httpOnly, so the frontend never handles the token
itself.
During development, run the backend on 8080 and point the Vite dev server's proxy at it:
VERDANDE_DATA_DIR=./data VERDANDE_DEV=true go run ./cmd/verdande
