- Edit and archive require the digest the board read (expect); the route
refuses a write without it.
- The edit dialog saves against the task it showed, so a poll that reads a
newer task turns a stale save into task-conflict; the dialog reopens on the
current task.
- An answer the board cannot read, or one marked sent=unknown, is shown as an
open outcome, not as a refusal.
- The per-org cap applies after the filters and keeps the most recently
changed tasks; projects, metrics and the inbox count every task. The board
sends project, state, assignee and label filters to the server.
- A poll keeps the focus, caret and scroll the person has at the moment it
answers, not when it started.
- An org whose tasks read fails shows "tasks not read" and is not writable.
- browser.test.mjs pins tasks-board.js in the script order.
