3f20999597 refactor(timeline): drop server-side comment + timeline pagination (#2322)
* refactor(timeline): drop server-side comment + timeline pagination (MUL-1929)

The cursor-paginated /timeline and /comments endpoints were sized for a
problem the data shape doesn't have: prod p99 is ~30 comments per issue
and the all-time max is ~1.1k. Time-based pagination also splits reply
threads across page boundaries (orphan replies), which the frontend was
papering over with an "orphan rescue" that promoted disconnected replies
to top-level — confusing UX with no real benefit.

Replace both endpoints with a single full-issue fetch, capped server-side
at 2000 rows as a defensive safety net (never hit in practice).

Server
- /api/issues/:id/timeline now returns a flat ASC TimelineEntry[]
  (matches the legacy desktop contract — older Multica.app builds keep
  working because the wrapped TimelineResponse + cursors are gone, and
  the raw array shape was always what they consumed).
- /api/issues/:id/comments drops limit/offset; only ?since is honoured
  for the CLI agent-polling flow.
- Drop ListCommentsBefore/After/Latest, ListActivitiesBefore/After/Latest
  and the timelineCursor encoding.
- Replace with ListCommentsForIssue / ListCommentsSinceForIssue /
  ListActivitiesForIssue (capped by argument).

CLI
- multica issue comment list drops --limit / --offset and the X-Total-Count
  reporting; --since is preserved for incremental polling.

Frontend
- Replace useInfiniteQuery with useQuery in useIssueTimeline; drop
  fetchOlder/Newer, jumpToLatest, isAtLatest, newEntriesBelowCount.
- Remove timeline-cache helpers (mapAllEntries / filterAllEntries /
  prependToLatestPage) and the TimelinePage / TimelinePageParam types.
- WS event handlers update the single flat-array cache directly.
- Drop the orphan-reply rescue in issue-detail — every reply's parent
  is now guaranteed to be in the same array.
- Strip the "show older / show newer / jump to latest" buttons and their
  i18n strings.

* fix(timeline): address review feedback on pagination removal

Three issues caught in PR #2322 review:

1. /timeline broke for stale clients between #2128 and this PR. They send
   ?limit/?before/?after/?around and parse with the wrapped TimelinePageSchema;
   the new flat-array response was failing schema validation and falling back
   to an empty timeline. Restore the wrapped shape on those query params
   (DESC entries, null cursors, has_more_*=false), keeping the flat ASC array
   for bare requests. Around-mode now also fills target_index from the merged
   slice so legacy clients can still scroll-to-anchor without a follow-up.

2. The agent prompts in runtime_config.go and prompt.go still told agents
   that `multica issue comment list` accepts --limit/--offset and to use
   `--limit 30` on truncated output. With those flags removed in this PR,
   new agent runs would hit "unknown flag" or skip context. Update the
   prompt copy to "returns all comments, capped at 2000; --since for
   incremental polling".

3. useCreateComment's onSuccess was a bare append to the timeline cache
   with no id-dedupe, so a fast comment:created WS event firing before
   onSuccess produced a transient duplicate. Restore the id guard the old
   prependToLatestPage helper used to provide.

Adds two new boundary tests:
- TestListTimeline_LegacyWrappedShape_OnPaginationParams
- TestListTimeline_LegacyWrappedShape_AroundFillsTargetIndex

* test(handler): fix timeline test assertions for handler-package isolation

The TestListTimeline_* assertions assumed CreateIssue would seed an
"issue_created" activity_log row, but the activity listener that publishes
those rows is registered in cmd/server/main.go — handler-package tests
don't wire it up. CI saw 5 entries (3 comments + 2 activities) where the
test expected ≥6.

Drop the auto-activity assumption: assert exactly 5 entries in
TestListTimeline_MergesCommentsAndActivities, and tighten
TestListTimeline_EmptyIssue to assert a fully-empty timeline.

6400868412 fix(timeline): off-by-one — exact-limit comments no longer triggers Show older (#2259)
Pre-fix the gate was `len(comments) >= limit`, which fired even when the
issue had EXACTLY <limit> comments. The "Show older" affordance appeared,
the user clicked, the next page fetched zero rows. User flagged it on
MUL-1857 — "this issue happens to have 30 comments; the button shouldn't
appear in that case."

The fix is the standard over-fetch probe: ask the SQL for limit+1 rows; if
it returned more than limit, drop the extra and report hasMore=true.
Otherwise hasMore=false.

- New helper `commentOverflow(rows, limit) -> ([]db.Comment, bool)` replaces
  the count-based `hasMoreCommentsBeyond`. Works for both DESC (latest /
  before) and ASC (after / around-newer) since both want "keep first
  <limit>".
- All four mode handlers (latest, before, after, around) now ask for
  limit+1 comments and route through the helper.
- Activities still cap at <limit> with no overflow probe — they don't gate
  pagination (#1857), so the boundary doesn't matter for them.

Tests:
- TestCommentOverflow pins the truth table with the boundary case
  ("exactly limit comments" → hasMore=false).
- TestListTimeline_ExactlyLimitCommentsHidesShowOlder is the DB-backed
  regression: 30 comments, limit=30, asserts has_more_before=false and
  next_cursor=nil.

161194b86f fix(timeline): exclude activities from comment page budget (#2253)
* fix(timeline): exclude activities from comment page budget

The /timeline endpoint paginated comments + activities through one shared
50-row budget, so an issue with a chatty agent (status flips, task_completed
markers, assignee toggles per run) could trigger "show older" with as few as
10-20 actual comments — users opened the page and thought their discussion
had vanished.

- Comment limit drops from 50 to 30 (the visible page size users wanted).
- has_more_before / has_more_after gate on comments alone via the new
  hasMoreCommentsBeyond helper. Activity rows still ride along at the same
  per-call SQL cap but no longer push real comments off-page.
- Merge functions stop truncating at the page limit; both pools are
  individually bounded by SQL, so dropping rows here only re-introduced the
  bug. The legacy (pre-cursor) path applies its 200-row cap inline.
- Test rewrite: TestHasMoreBeyond → TestHasMoreCommentsBeyond, replaced the
  #2192 merge-truncation regression with a #1857 "dense activity does not
  hide comments" test that pins the new contract directly.

* fix(timeline): per-pool keyset cursor for comments and activities

Pre-fix, next_cursor / prev_cursor anchored on the merged page boundary
(oldest / newest entry overall). When activity rows were older than every
fetched comment — common on issues created with a status change before the
first comment — the latest page emitted a cursor pointing at that activity,
and the next "show older" call sent that timestamp into ListCommentsBefore,
skipping every unreturned comment in between. GPT-Boy flagged this on
PR #2253 with the 80-comment / 30-activity scenario where 50 comments
became permanently unreachable.

The fix splits the cursor into independent comment and activity positions:

- timelineCursor carries (CommentT, CommentID, ActivityT, ActivityID).
  encode/decode signatures changed accordingly.
- New cursorPos type and four bounds helpers (commentBoundsDesc / Asc,
  activityBoundsDesc / Asc) extract per-pool oldest/newest from fetched
  rows, with a carry fallback so empty pools advance past the input cursor
  instead of resetting.
- All four mode handlers (latest, before, after, around) now derive cursors
  from each pool's own bounds. Removed the entryTimestamp / entryID helpers
  that re-parsed the merged entry slice.

Tests:
- TestTimelineCursor_RoundTrip pins the encode/decode contract for the new
  dual-pool format (and rejects garbage input).
- TestListTimeline_PerPoolCursorWalksAllComments reproduces GPT-Boy's exact
  scenario (30 activities older than 80 comments, limit=30) and asserts
  every comment is reachable through repeated `before=<cursor>` walks.

099dda0603 fix(timeline): include merge-truncation case in has_more_before (#2192) (#2204)
* fix(timeline): include merge-truncation case in has_more_before (#2192)

Older comments became unreachable on issues where activity-log entries
crowded them out of the latest 50-entry page. The 'show earlier' button
was hidden and no cursor was emitted because the has_more_before formula
only caught the per-table SQL cap case and missed the in-memory merge
truncation case.

Reproduces with 48 comments + 49 activities, default limit 50: neither
table individually returns >= limit rows, but their sum (97) exceeds the
merged page size, so the merge silently drops 47 older comments. The old
formula reported has_more_before=false; the client never asked for page 2.

Fix: extract hasMoreBeyond(c, a, e, limit) with the missing third
disjunct - comments + activities > entries - applied uniformly to
listTimelineLatest / Before / After / Around.

Backwards compatible: API contract unchanged. Pre-cursor clients
(<=v0.2.25) still hit listTimelineLegacy and never read these fields.
Newer clients see has_more_before flip from 'wrongly false' to correctly
true/false - no field renames, no shape changes.

* fix(issues): show count badge when activities are coalesced (#2192)

The timeline coalesces consecutive same-actor + same-action activities
within a 2-minute window so 48 status_changed entries don't take 48 rows.
The count badge was only rendered for task_completed / task_failed; for
status_changed (and every other action) the coalesced batch silently
collapsed to a single line with no hint that N entries were merged.

Add a coalesced_badge translation and render '×N' next to the activity
text whenever coalesced_count > 1, suppressing it on task_completed /
task_failed which already include the count in their translation copy.

This pairs with the backend fix for #2192: once the older-comments page
becomes reachable again, the activity rows above it should make the
density of the merged batch visible rather than misleading the user
into thinking only one event happened.

11a6288cbd fix(timeline): legacy array shape for pre-#2128 clients (#2143, #2147) (#2156)
#2128 changed GET /api/issues/:id/timeline from a bare TimelineEntry[] to
a wrapped { entries, next_cursor, ... } object. Multica.app ≤ v0.2.25 still
in the wild reads the response body as TimelineEntry[] directly, so the
moment v0.2.26 backend rolled out, every old desktop hit
"timeline.filter is not a function" on any issue open — bug reports landed
within ten minutes of the v0.2.26 release (#2143, #2147).

The new client always sends ?limit=..., so absence of every pagination
param uniquely identifies a legacy caller. Detect that at the top of
ListTimeline and serve the old shape (ASC, []TimelineEntry, capped at 200)
through a dedicated listTimelineLegacy helper. New clients fall through
unchanged.

A new TestListTimeline_LegacyShapeForPreCursorClients pins the contract
(array shape, ASC order, "[]" not "null" on empty issues). Two existing
tests that used the empty query string have been updated to send
?limit=50, since the empty form is now reserved for the compat path.

The legacy branch can be deleted once desktop auto-update has rolled the
user base past v0.2.26.

ba147708a6 fix(timeline): cursor-paginated timeline to stop long-issue freeze (#1968) (#2128)
* fix(timeline): cursor-paginated timeline to stop long-issue freeze (#1968)

Opening an issue from Inbox with thousands of timeline entries used to
hard-freeze the browser tab on a synchronous render of every comment +
activity. The whole pipeline was unbounded: the API returned every row,
TanStack Query cached the full array, and IssueDetail mounted N
CommentCards (each running a full react-markdown + lowlight pipeline)
in one frame.

This swaps the timeline endpoint to keyset cursor pagination and rewires
the frontend to useInfiniteQuery so a long issue costs the same as a
short one on first paint.

API:
- GET /issues/:id/timeline now accepts ?before / ?after / ?around (mutex)
  + ?limit (default 50, max 100); response wraps entries with next/prev
  cursors and has_more flags. Cursors are opaque base64 (created_at, id).
- ?around=<entry_id> anchors a window on the target so Inbox notifications
  pointing at an old comment never trigger the freeze.
- New composite indexes on (issue_id, created_at DESC, id DESC) replace
  the redundant single-column ones so keyset queries are index-only scans.
- /issues/:id/comments default branch now caps at 50 instead of returning
  every row unbounded; the unbounded ListComments / ListActivities sqlc
  queries are deleted.

Frontend:
- useIssueTimeline switches to useInfiniteQuery, exposes
  fetchOlder/fetchNewer/jumpToLatest + isAtLatest + newEntriesBelowCount.
- WS handlers respect the at-latest invariant: comment/activity:created
  prepends to pages[0] only when the user is reading the live tail;
  otherwise it just bumps a counter so the UI offers a "Jump to latest"
  affordance without yanking scroll.
- Optimistic mutations adapted to the InfiniteData shape via shared
  helpers (mapAllEntries / filterAllEntries / prependToLatestPage in
  core/issues/timeline-cache.ts) and use setQueriesData so all open
  windows of the same issue stay in sync.
- IssueDetail Activity section gets a TimelineSkeleton placeholder
  during the brief load window plus subtle text-link load-more buttons
  matching the existing Subscribe affordance (no Button chrome). Top
  uses a divider for boundary clarity; bottom shows
  "Jump to latest · N new" weighted slightly heavier when there's
  unread state.
- highlightCommentId now flows into the hook's around parameter so
  Inbox jumps fetch the surrounding 50 entries directly.

* chore(agent): default comment list to 50 + prompt hint about long issues

The CLI's "multica issue comment list" used to default to --limit 0
(meaning "fetch every comment"), which lets an agent on a long issue
fill its context window with thousands of rows. The default is now 50;
agents that need older history can pass --limit or --since explicitly.

The local-coding-agent prompt also gains a single-line note about this
in both the comment-triggered and on-assign flows so the agent knows to
scope its fetches when issue size is unknown. Autopilot run-only mode
is intentionally unchanged — it has no issue context to query.

951f51408a fix(agent/comments): prevent resumed sessions from reusing stale --parent UUID (#1374)
* fix(agent/comments): re-emit trigger comment id every turn + server-side parent_id guard

Resumed Claude sessions keep prior turns' tool calls in context, so a
comment-triggered task could reuse the PREVIOUS turn's --parent UUID
instead of the current trigger's. The reply landed in the wrong thread
(MUL-1125): backend stored exactly what the agent sent, but the agent
pulled a stale UUID from its own conversation memory.

Two layers of defense:

1. Extract BuildCommentReplyInstructions so daemon.buildCommentPrompt
   and execenv.InjectRuntimeConfig emit the same "use this exact
   --parent, do not reuse values from previous turns" block. The
   per-turn prompt now carries the current TriggerCommentID, which it
   previously relied on CLAUDE.md for (and CLAUDE.md isn't re-read
   mid-session).

2. Handler-side guard in CreateComment: when an agent posts from inside
   a comment-triggered task (X-Agent-ID + X-Task-ID, task has
   TriggerCommentID), require parent_id == task.TriggerCommentID or
   return 409. Assignment-triggered tasks are untouched.

* fix(agent/comments): scope parent_id guard to the task's own issue

Two issues from CI + GPT-Boy's review:

1. Guard was too broad: the CLI stamps X-Task-ID on every request, so an
   agent legitimately commenting on a different issue while its current
   task was comment-triggered would get 409'd with the wrong issue's
   trigger comment id. Narrow the guard to fire only when the request's
   issue matches the task's own issue — cross-issue agent activity
   stays unblocked.

2. The integration test tried to insert a second queued task for the
   same (agent, issue), which hits the idx_one_pending_task_per_issue_agent
   unique index. Replace the assignment-triggered-task sub-case with a
   cross-issue regression test (the scenario we now need to cover anyway):
   post on issue B while X-Task-ID points at a comment-triggered task on
   issue A, expect 201.

e7fe6ea79b feat(activity): unified activity timeline with comment reply support
Replace the comment-only list with a Linear-style unified timeline that
interleaves field changes and comments chronologically.

Backend:
- activity_listeners.go: records field changes (status, assignee, description,
  task completed/failed) to activity_log table on domain events
- Timeline API: GET /api/issues/{id}/timeline merges activity_log + comments
  sorted by created_at
- Comment reply: parent_id column + handler support for threading

Frontend:
- Unified timeline replaces comment list: activity entries as compact muted
  lines, comments as Card components with reply threading
- Filter toggle (All / Comments / Activity)
- Reply UI: inline editor under comments with Cancel/Reply buttons
- Real-time sync for activity:created + comment events
- 10 new Go tests, all passing
