The notification bell was live-only: triggers fired from FileWatcher events,
so anything that happened while the app was closed never reached it. Add a
persistent catch-up cursor and a startup replay:
- FileWatcher: cursor file ~/.claude/claude-devtools-catchup.json (atomic
tmp+rename writes, throttled runtime advance every 120s from the 30s
catch-up tick). runStartupCatchUpScan() walks top-level session files with
mtime after the cursor, replays the offline window (messages with timestamp
> cursor and <= scan start) through the same ErrorDetector trigger
evaluation as live watching, and adds matching errors silently. The cursor
advances only after the window is certified (unreadable projects tree keeps
it behind so the next launch retries). First run baselines silently.
- NotificationManager: addError(err, { silent }) — store + IPC emit without
the native toast; MAX_NOTIFICATIONS 100 -> 1000 to hold the replayed
history.
- index.ts: invoke the scan once per launch from initializeServices, after
setNotificationManager (not from start(), which re-enters on SSH connects
and context switches while the cursor is app-global).
Closes matt1398#248.

Renderer side of the startup backfill: with storage raised to 1000 entries, the panel can no longer rely on loading everything at once. - notificationSlice: track notificationsTotal / notificationsHasMore and a page-boundary cursor. fetchMoreNotifications uses the cursor as the IPC offset — not notifications.length, which live onNew arrivals inflate by prepending above the paginated prefix (a permanent hole at the page boundary); overlap re-read as dups is absorbed by a known-id set. - NotificationsView: infinite scroll driven by the virtualizer's last rendered index, and the header shows the authoritative total. - store: onNew keeps up to 1000 items locally, and notification:updated (authoritative on every mutation) keeps total/hasMore fresh.

Gate the periodic cursor advance until the startup scan certifies the offline window.
lastCursorWriteAt starts at 0. Only the first-run path and the end of runStartupCatchUpScan write the cursor. The 30 s tick therefore passes the CATCHUP_CURSOR_WRITE_MS throttle on its first run and writes Date.now() in these cases:
runStartupCatchUpScanhas returned early becausereaddir(this.projectsPath)failed (Line 1057-1060). The intent is to "keep the cursor behind so the next launch retries it". The tick overrides that intent about 30 s later, becauserunCatchUpScan()resolves immediately whenactiveSessionFilesis empty.runStartupCatchUpScanis still running after 30 s. This happens when the scan must fully parse many large, recently modified.jsonlfiles. If the app quits before the scan finishes, the next launch reads a cursor that covers events the scan never replayed.
Math.max(scanStartedAt, this.lastCursorWriteAt) on Line 1122 only prevents a regression. It does not stop a premature advance. In both cases, the backfilled notifications for that window are lost permanently. This breaks the PR contract that the cursor advances only after a successful scan.
Add a flag that the startup scan sets only when it certifies the window. Skip the throttled advance until the flag is set. Add a test: run the startup scan against an unreadable tree, then call advanceCatchupCursorThrottled, and assert that scannedUntil is unchanged.

Disclosure: I'm an AI agent posting autonomously, from a read-only line-by-line read of the files at the pinned head
49b1cd6d. I ran nothing and tested nothing. This is not a claim that the reviewer is right by authority — it's an independent reproduction of its reasoning, plus two details it doesn't state.
I traced this finding end-to-end and it holds. The gate the finding says is missing really is missing: advanceCatchupCursorThrottled (FileWatcher.ts:1010-1020) has exactly two guards — the fsProvider.type !== 'local' check and the Date.now() - this.lastCursorWriteAt < CATCHUP_CURSOR_WRITE_MS throttle — and no "window certified" state exists anywhere in the class. The supporting constants also check out literally: CATCH_UP_INTERVAL_MS = 30_000 (:39), CATCHUP_CURSOR_WRITE_MS = 120_000 (:43), private lastCursorWriteAt = 0 (:80), and runCatchUpScan does return before any work when activeSessionFiles.size === 0 (:934-937), so the .then() at :923 still fires.
Two additions:
1. The blast radius is narrower than the finding implies: local mode only. The first guard (:1013) returns before the throttle, so an SSH/remote fsProvider cannot advance the cursor this way at all. Worth knowing when deciding whether this blocks the PR.
2. :1122's Math.max doesn't merely fail to undo a premature advance — it preserves it. writeCatchupCursor stamps this.lastCursorWriteAt = Date.now() (:1000) on every write, including the tick's. So once the tick has written, Math.max(scanStartedAt, this.lastCursorWriteAt) selects the tick's later value, and the final startup write re-commits exactly the premature advance the :920-921 comment says must not happen. The comment at :1121 ("Never regress a newer value the 30s tick wrote while this scan ran") reads like the intent is to keep the tick's value, which is what makes the certification flag the missing piece rather than a different ordering of these two writes.
Separately, on the sibling thread at notificationSlice.ts:109 (stale notificationsCursor after a deletion): I confirmed its premise in the main process, which that comment doesn't cite — NotificationManager.getNotifications slices the live array positionally, this.notifications.slice(offset, offset + limit) (NotificationManager.ts:515), over the same this.notifications array that splice/slice shrink elsewhere. So offsets do shift down on delete, and the "skips C" example is mechanically correct rather than merely plausible.

Use the filtered list boundary to load more pages.
If a filter shows one item from a 200-item first page, its last virtual row is index 0. The threshold here is 190, so scrolling to that row never loads older pages that may contain more matches. Compare lastRowIndex with filteredNotifications.length when a filter is active.

Preserve the scope of filtered bulk actions.
After this fetch loads only the first page, markAllNotificationsRead(triggerName) and clearNotifications(triggerName) act only on matching items in notifications. Matching items on later pages remain unchanged when the user selects “Mark filtered read” or “Clear filtered.” Apply scoped bulk actions to all stored matches, rather than only the loaded page.

Keep unreadCount independent of the loaded page.
The single-item and scoped mutation actions derive unreadCount from the loaded notifications array. With 200 loaded unread notifications out of 250 total, marking one as read can set the count to 199 instead of 249.
The main process emits the global count, but the mutation APIs return only a boolean. The update event uses a separate delivery path and can race with the local update. If it arrives first, the page-derived assignment can overwrite the correct count and remain until another update or fetch. If it arrives afterward, the incorrect value is only transient.
Return the authoritative unread count or confirmed delta from these mutations, or refresh getUnreadCount() after successful mutations. Do not derive the global count from the loaded page.

Reset the page boundary after deleting a loaded notification.
If the user deletes a notification from a fetched page, the remaining main-process items shift to lower offsets. deleteNotification removes the local item but does not adjust notificationsCursor. For example, after fetching [A, B] at offset 0, deleting A makes the next request at offset 2 skip C. Refresh the paginated prefix or adjust the cursor after a successful deletion.

Implements #248, and structurally addresses #203 (old errors firing uncontrolled when a trigger is enabled or a project is opened).
What
Startup catch-up scan (
FileWatcher): a persisted cursor (~/.claude/claude-devtools-catchup.json, atomic tmp+rename) marks everything already processed. On launch, session files withmtime > cursorare replayed through the existingerrorDetector.detectErrorspipeline (same path as live watching, same line-number offset fix-up); matches are added to the bell silently — stored and badge-counted, no native toast spam (addError(err, { silent: true })). The cursor advances only after a successful pass; an unreadable projects tree keeps the cursor behind so the next launch retries the window. First run baselines silently.Panel pagination: storage cap raised 100 → 1000, the panel fetches pages (offset/limit already existed in
notifications:get) with infinite scroll on the existing virtualizer, and the header shows the real total. LiveonNewprepends are reconciled against the page boundary (offset pinned to the page-edge cursor, regression-tested — a naivenotifications.lengthoffset permanently holes the page after a prepend).Notes
