+The Project board reads every page of its GitHub pull-request and issue lists instead of the first hundred rows, so its seven-day merge and close medians and its day counts now cover the whole window rather than roughly the newest three days ([#2650](https://github.com/ThinkFlowLab/FlyBot/issues/2650)).

 ## Project metrics (#1829)
 
-`core/src/host/project-metrics.js` answers the Project board's seven numbers: PRs opened and merged today, issues opened and closed today, and the seven-day medians of PR merge, issue close and task completion durations. The four day counts compare `created_at` / `merged_at` / `closed_at` against the reader's own time zone (`Intl.DateTimeFormat`), not the host clock — the zone arrives in the request body, so `resolveTimeZone` validates it once and an unknown name answers the named `UTC` instead of throwing out of the whole board read, rows, queues and decisions with it (#1849) — and the local task half reads `createdAt` and the last terminal `actors[].at` (falling back to `completedAt`, then `updatedAt`) and counts only `accepted` cards. The running table and the task-done median read one board's own cards, not the deployment's task store: `project-board.js` hands `readMetrics` the same `mine` list its rows were built from (#1848), so a card of another Project, or one this reader is refused, appears in neither, and every branch (no credential, no fetch, a failed read, a cache hit, a success) reproduces both from that same list. The five-minute cache is shared by every Project on the repository, so an entry holds only the repository-level numbers (`ok`, the time zone, the stamp and the six GitHub counts and medians); `running` and `taskDoneMedianMs` are re-projected from the caller's cards on a hit exactly as on a miss (#1880). The numbers ride on the existing `project-board` endpoint (`store.js` carries the `metrics` section beside the rows), which passes the host secret store's `GITHUB_TOKEN` and the reader's time zone from the request, requires the Project, and answers `ok: false` with `null` values when the credential is missing or a read fails — the client paints `—`, never `0`. One five-minute in-process cache keys on repository, time zone and window, so a hit spends no source call; a failed read is not cached. `runningOf` projects a claimed card into the running table's row (who, claim age, source, last activity).
