Second step of the virtualization plan. No virtualization yet. This PR
makes IntersectionObserver-based visibility tracking correct inside
scroll containers (sidebar, bottom-sheet), which is a prerequisite for
virtualizing the timeline.
- Introduces `TimelineViewport` — a grouped contract passed as a single
`viewport` prop on `ActivityTimeline`. Holds `scrollElementRef`,
`observerRoot`, `scrollMargin`, and `virtualizationEnabled`.
- `MessageRowWithObserver` and `LeadThoughtsGroupRow` now create their
`IntersectionObserver` with `root = observerRoot?.current ?? null`
instead of defaulting to the document viewport. Unread marking now
fires when rows enter their real scroll parent.
- `MessagesPanel` resolves the active scroll owner from `position`
(inline from parent ref, sidebar from `sidebarScrollRef`, bottom-sheet
from `bottomSheetScrollRef`) and passes it into ActivityTimeline.
- Tests: stubs `IntersectionObserver` to capture `options.root` and
asserts null when no viewport is passed, and the provided element when
`viewport.observerRoot` is set.
`scrollMargin` and `virtualizationEnabled` are included in the contract
but not consumed yet — they land in follow-up PRs (#4/#5).
- Introduced caching mechanism with expiration for message feeds to improve performance.
- Added logging for cache expiration events to aid in debugging.
- Updated MessagesPanel to reopen search bar when participant filters are active.
- Added test cases for handling tmux server errors and message panel behavior with filters.
First step toward virtualizing ActivityTimeline. Makes the real scroll
container observable per layout, without changing behavior.
- `TeamDetailView` forwards `contentRef` to `MessagesPanel` as
`inlineScrollContainerRef`. `MessagesPanel` accepts it as an optional
prop (unused in this release) so a follow-up can wire the inline
viewport to virtualization consumers.
- `MessagesPanel` creates `bottomSheetScrollRef` and passes it to
`Sheet.Content scrollRef`. react-modal-sheet merges it with its
internal scroll ref, so the element stays the same DOM node; this
only exposes it to us.
- Sidebar already owns `sidebarScrollRef`; no change there.
Behavior is unchanged — this only exposes refs for the follow-up that
will thread a viewport contract into ActivityTimeline.
- Integrated pending replies state management for team members.
- Updated TeamDetailView to initialize pending replies from state.
- Added logic to refresh team messages and member activity on tab focus.
- Improved UI components by increasing dialog content width for better layout.
- Enhanced member draft rows with avatar support for better visual representation.
- Implemented reconciliation logic for pending replies based on message history.
- Updated tests to cover new functionality and ensure reliability.
- Bumped pnpm version to 10.33.0 in package.json.
- Added existing members to EditTeamDialog for better context.
- Improved buildMemberDraftColorMap to reserve colors for existing members and predict colors for new drafts.
- Added tests to ensure color assignment logic works correctly for existing and new members.
Replace the per-item backward scan that located the most recent session
anchor with a single forward pass via useMemo.
Before: for every timeline item the render loop walked backward until
it found a lead-thought anchor, so N items produced up to N * N anchor
lookups on every render pass.
After: a single O(n) sweep builds previousSessionAnchorByIndex; render
time lookup is O(1). getItemSessionAnchorId is hoisted to module scope
so it is not recreated per render.
Behavior is unchanged. The three existing separator tests still pass,
and four new cases cover three-session transitions, long runs of
non-anchor items between thought groups, consecutive same-session
thoughts, and single-item lists.

P1: Poller no longer overwrites nextCursor/hasMore — those belong
to the "Load older" flow. Both poller and loadOlder now dedup
messages by messageId or timestamp+from fingerprint.
P1: Cursor is now compound (timestamp|messageId) with stable
tie-breaking sort. Messages sharing the same timestamp at page
boundaries are no longer lost.
P2: getMessagesPage now applies the same enrichment as getTeamData:
leadSessionId propagation and slash-command-result annotation.
P3: Added 3 tests for getMessagesPage covering pagination, cursor
stability with same-timestamp messages, and slash command annotation.
New cursor-based IPC endpoint for the messages timeline panel:
- team:getMessagesPage(teamName, { beforeTimestamp?, limit? })
returns { messages, nextCursor, hasMore }
- Cursor is timestamp-based — stable under live message insertion
- Default page size 50, max 200
getTeamData no longer includes messages in its response, eliminating
the ~1MB messages payload from every team refresh. Messages are now
fetched independently by MessagesPanel.
MessagesPanel changes:
- Fetches initial page on mount via getMessagesPage API
- Auto-refreshes newest page every 5s when team is alive
- "Load older messages" button for pagination
- Falls back to prop messages if API fails (graceful degradation)
- Move endRefreshing() outside the !cancelled guard in finally block
so it always runs even when the effect is torn down mid-refresh.
- Only call load() when isTabActive or on first load — prevents
unnecessary fetches when a hidden tab's effect re-runs.
Critical:
- findLogsForTask: call worker directly instead of wrapping in
wrapTeamHandler, so failures propagate to catch and trigger the
main-thread fallback correctly.
- TeamDataWorkerClient: scope error/exit handlers to the specific
worker instance to prevent a stale worker's exit event from
rejecting pending requests on a replacement worker (race condition).
Major:
- TeamDataWorkerClient: validate teamName and taskId before forwarding
to worker thread (input sanitization).
- team-data-worker: include status, since, and intervals length in
cache key to prevent stale results after filter changes.
- team-data-worker: move logsInFlight.delete() into .finally() so
rejected lookups don't poison the in-flight map permanently.
- MemberLogsTab: reset refreshCountRef and refreshing state in effect
cleanup to prevent the refresh indicator from latching on permanently
when the effect tears down mid-refresh (e.g. on tab switch).
Main process — worker thread for team data:
- New team-data-worker thread handles getTeamData and findLogsForTask,
isolating heavy file I/O (scanning 300+ subagent JSONL files) from
Electron's main event loop. getTeamData dropped from ~2000ms on the
main thread to ~110ms via the worker.
- Worker-side dedup and 10s result cache for findLogsForTask prevents
redundant scans when the same task is queried multiple times.
- Discovery cache TTL raised from 5s to 30s — avoids re-scanning the
entire project directory on every call.
- Message cap at 200 in TeamDataService to keep IPC payloads under 1MB
(was sending 2200+ messages / ~3MB, stalling Chromium IPC serialization).
- IPC handlers fall back to main-thread execution if the worker is
unavailable (graceful degradation).
Renderer — useShallow and memoization (55 files):
- Added useShallow to store selectors across 55 renderer files. Batched
individual useStore() calls (e.g. 17 calls in ExtensionStoreView,
10 in ConnectionSection) into single useShallow selectors, cutting
unnecessary re-render checks on every store update.
- MemberLogsTab: three 5-second polling intervals now pause when the
parent tab is hidden (display:none). Previously 5 hidden tabs × 3
intervals = 15 polling timers firing continuously.
- KanbanColumn wrapped in React.memo to skip re-renders when props
haven't changed.
- MemberList: memoized activeMembers/removedMembers/colorMap; replaced
O(n×m) per-member task scan with a pre-computed reviewer map.
- Bounded timer Maps in store initialization to prevent unbounded growth
of debounce/throttle tracking maps during long sessions.
