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 interface for phase 1: sign-in and first-run setup, Today, Upcoming,
project views, sharing, Cmd+K search and the keyboard shortcuts.
Quick add highlights what the parser understood underneath the text as
you type — a mirrored layer behind a transparent input, sliced by byte
offset because the server counts bytes and JavaScript counts UTF-16
units, which disagree on exactly the Danish letters this app is full of.
Every local action is optimistic and reconciled afterwards: ticking a
task off strikes it through and animates it out before the request
leaves, and rolls back with a message if the server disagrees.
The Content-Security-Policy is computed at startup by hashing the inline
scripts in the built index.html. Both of them change on every frontend
build, so a hard-coded hash would go stale silently and show up only as
a blank page in production. The alternative, 'unsafe-inline', would drop
the one protection that makes an injected script in a task title inert.
Today is derived from the store by date rather than from the ids that
came back with the first request — filtering against a captured list
meant a task added through quick add never appeared until a reload.
