24b162cdbc feat(daemon): surface the real task initiator to the agent runtime (MUL-2645) (#3899)
* feat(daemon): surface the real task initiator to the agent runtime (MUL-2645)

In a multi-person workspace the agent runtime only ever saw the runtime
OWNER identity: the brief's `## Requesting User` is sourced from
runtime.OwnerID and the task-scoped token is owner-bound, so every
requester (whoever commented, @mentioned, or chatted) appeared to the
agent as the owner. Agents that route by initiator for permission,
privacy, or audit all misjudged.

Resolve the real task initiator at claim time and surface it distinctly
from the owner:
- comment / mention trigger -> triggering comment's author (member or agent)
- chat task -> chat session creator (sessions are creator-only)
- on-assign / autopilot / quick-create -> no attributable initiator (omitted)

Adds initiator_{type,id,name,email} to the claim response, the daemon
Task, and TaskContextForEnv, rendered into the brief as a new
`## Task Initiator` section. The section documents the privacy boundary:
the agent's credentials stay owner-scoped, so this is an attested
identity for the agent's own routing/privacy logic, not act-as. No DB
migration — both paths are derivable from existing rows.

Tests: brief rendering (member/agent/omit/sanitize) + email guard unit
tests, and claim-handler tests for the comment and chat paths.

* fix(chat): store real sender as task initiator, not chat_session creator (MUL-2645)

Review fix (Niko, PR #3899). v1 resolved the chat task initiator from
chat_session.creator_id at claim time. That is correct for web chat and
Lark p2p (creator == sender), but WRONG for Lark group chats: the group
session creator is deliberately the installer (stable identity across
member churn), not the message sender. So in a Lark group, every member
who triggered the agent showed up in the brief as the installer/owner —
the exact bug this issue is about, still live at that entry point.

Capture the real sender at enqueue time instead of deriving it from the
session creator at claim time:

- migration 117: agent_task_queue.initiator_user_id (FK user, ON DELETE
  SET NULL); NULL for non-chat and pre-migration rows.
- EnqueueChatTask now takes an explicit initiatorUserID. Web chat passes
  the authenticated request user; the Lark dispatcher threads the inbound
  sender (binding.MulticaUserID) through scheduleRun -> flushChatRun. The
  debouncer keeps the latest scheduled flush per session, so in a multi-
  sender silence window the LATEST sender wins (documented + tested).
- claim handler resolves the initiator from task.initiator_user_id and
  drops the creator_id fallback entirely.

The Lark group session creator stays the installer (unchanged) — only the
task initiator is corrected, keeping the two concepts cleanly separate.

Tests: dispatcher group regression (initiator = sender, not installer),
latest-sender-wins, p2p initiator assertion; the chat claim handler test
now sets creator != initiator and asserts the stored sender wins.

de900b2ba6 feat(server): funnel/community/commercial business metrics + PostHog pairing (MUL-2949) (#3698)
* feat(server): funnel/community/commercial business metrics + PostHog pairing (MUL-2949)

PR3 of the Grafana board metrics split (parent MUL-2328).

Adds 23 new Prometheus counter/histogram families to the PR2 BusinessMetrics
collector covering the activation/community/commercial funnels, and binds
every PostHog event emission to a matching metric increment so the two sides
cannot drift.

Funnel: signup, workspace_created, team_invite_sent/accepted, onboarding_*,
cloud_waitlist_joined.
Content: issue_created, chat_message_sent, agent_created, squad_created,
autopilot_created, issue_executed.
Runtime: runtime_registered/ready/failed/offline + ready_seconds histogram,
daemon_ws_message_received_total.
Autopilot: autopilot_run_started/terminal/skipped.
Webhook/GitHub: webhook_delivery_total, github_event_received_total,
github_pr_review_total, github_pr_merge_seconds histogram.
CloudRuntime: cloudruntime_request_total + duration histogram, wired through
a small RequestRecorder interface so the cloudruntime package stays decoupled
from metrics.
Commercial: feedback_submitted, contact_sales_submitted.

The pairing helper metrics.RecordEvent(client, m, ev) emits the PostHog
event AND increments the matching counter via IncForEvent dispatch, reading
labels from the analytics event Properties. Every existing
h.Analytics.Capture(analytics.X(...)) call site has been migrated to the
helper across handler/, service/, and cmd/server/runtime_sweeper.go.

Lint enforcement (server/internal/metrics/business_pairing_test.go):
- TestEveryAnalyticsEventHasPrometheusCounter: every Event* constant in
  analytics/events.go either dispatches via IncForEvent or is in the
  taskMetricEvents allow-list (PR2 typed RecordTask* methods).
- TestNoNakedAnalyticsCaptureInHandlersOrServices: AST-walks handler/
  service/cmd-server for direct Analytics.Capture(...) calls — only
  service/task.go's captureTaskEvent helper is allow-listed.
- TestEveryAnalyticsRecordEventTakesAnalyticsHelper: validates the third
  arg of every metrics.RecordEvent call is built from analytics.*.

Cardinality protection: all new label values pass through fixed allow-lists
in labels_pr3.go; unknown values collapse to 'other'/'unknown'/'error'.

Refs:
- Spec MUL-2328 / MUL-2949.
- Builds on PR2 (MUL-2948) — collectors registered through the same
  BusinessMetrics struct, no separate Registry.
- Uses PR1's taskfailure.Reason (MUL-2946) for runtime_failed's failure_reason
  label via NormalizeFailureReason.

Out of scope: Sampler-class metrics (PR4 / MUL-2947), pr_review_total
emission point (no review event handler exists yet — counter is defined,
TODO to wire up when /api/webhooks/github grows pull_request_review handling).

* fix(server): tighten PR3 review items — signup_source bucket, fill platform/kind/form_source enums, onboarding_started server emission, lint scope (MUL-2949)

Addresses 张大彪's review on #3698:

1. signup_source: NormalizeSignupSource added to labels_pr3.go with a
   fixed allow-list bucket (direct/google/twitter/linkedin/.../other).
   Parses JSON cookie payload for utm_source/source/referrer fields,
   strips URL schemes, maps well-known hostnames to channel buckets.
   PostHog event still ships the raw cookie value for analytics; only
   the Prometheus label is bucketed.

2. Filled the unknown/other label gaps:
   - analytics.IssueCreated and analytics.ChatMessageSent now take a
     platform parameter sourced from middleware.ClientMetadataFromContext
     (X-Client-Platform header) at the handler. Autopilot-originated
     issues stamp PlatformServer.
   - analytics.FeedbackSubmitted now takes a kind parameter; CreateFeedback
     reads req.Kind (default "general") so the picker selection lights up
     the metric's kind label instead of long-term "other".
   - analytics.ContactSalesSubmitted now takes a formSource (page /
     onboarding / agents_page); CreateContactSales reads req.Source.
     The metric reads ev.Properties["form_source"] so the analytics
     CoreProperties.Source ("marketing_contact_sales") stays
     backward-compat for PostHog dashboards.

3. analytics.OnboardingStarted helper added; server-side emission lives
   in PatchOnboarding, fired exactly once per user on the first PATCH
   that carries a non-empty questionnaire payload (firstTouch logic
   compares prior bytes against {} / null). Frontend onboarding_started
   keeps firing on page open; the server emission is what guarantees the
   Prometheus counter exists so Grafana can be cross-checked against the
   PostHog funnel without depending on the SDK roundtrip.

4. business_pairing_test.go tightened:
   - TestNoNakedAnalyticsCaptureInHandlersOrServices now allow-lists at
     function granularity (just captureTaskEvent in service/task.go), not
     whole-file. Any future naked Capture in the same file fails CI.
   - TestEveryAnalyticsRecordEventTakesAnalyticsHelper now does def-use
     tracking inside the enclosing FuncDecl: when RecordEvent's third
     arg is an *ast.Ident, the test walks the function body for the
     assignment that defined it and confirms the RHS is an
     analytics.<Helper>(...) call. Bare local idents that didn't
     originate from analytics are now caught.

5. gofmt -w applied across the touched files; gofmt -l clean.

Tests: go test ./internal/metrics/... ./internal/analytics/... pass.
Pre-existing TestClaimTask_/TestWebhook_MergedPR/TestDeleteIssueByIdentifier
failures on origin/main are DB-environment-dependent and not regressions
from this change.

* fix(server): normalise onboarding_started platform label + regression test (MUL-2949)

Addresses 张大彪's last review nit:

- IncForEvent's EventOnboardingStarted case now wraps the platform
  property with NormalizePlatform, matching every other platform-bearing
  metric. A misbehaving frontend can no longer leak a raw X-Client-Platform
  header value into the multica_onboarding_started_total{platform=...}
  series.

- New labels_pr3_test.go covers every PR3 normalizer with both a happy-path
  value and an unknown value, asserting the unknown collapses to the
  documented fallback bucket. Includes a focused regression for
  onboarding_started: emits one event with an attacker-shaped platform
  string and asserts the metric only exposes web + unknown label values
  (no raw header bleed).

- testutil.go gains a small GatherForTest helper so the regression test
  can pull the typed MetricFamily map without re-implementing the
  registry-walk dance.

Co-authored-by: multica-agent <github@multica.ai>

* fix(server): NormalizeTaskSource on workspace_created + document lint limitations (MUL-2949)

Final review touch-ups before merge:

- IncForEvent's EventWorkspaceCreated case wraps source through
  NormalizeTaskSource, matching the other source-bearing dispatches
  (issue_created, agent_created, issue_executed). Closes the last raw
  property leak in the dispatcher table.

- business_pairing_test.go inline docstrings now spell out the two
  known limitations of the lint gate that 张大彪 / Eve flagged:
  analyticsBackedIdents matches by ident NAME (not SSA def-use, so a
  nested-scope shadow could pass) and isMetricsRecordEvent hard-codes
  the import alias set. PR description carries a Follow-ups section
  with the same two items so the work is visible after merge.

* fix(chat): fall back to legacy /messages when paged endpoint 404s

Deployment-order compatibility: a backend deployed before the
/messages/page endpoint existed returns 404 for the unknown route.
The cursorless initial page now falls back to the legacy full-list
/messages endpoint and wraps it in a single has_more:false page, so
chat never white-screens regardless of which side deploys first. A 404
on a cursor request still propagates to avoid duplicating the full list.

674be86add fix(tasks): cancel autopilot run_only & quick_create tasks (MUL-2827) (#3615)
CancelTaskByUser (POST /api/tasks/{taskId}/cancel) keyed cancellation off
issue_id / chat_session_id alone, so any task whose only source link was
autopilot_run_id (run_only autopilots) or quick_create context fell into the
dead else branch and 404'd with "task not found" — even though the task was
visible (and showed a cancel X) on the agent Activity tab.

Enforce tenancy uniformly through the task's owning agent instead: agent_id is
NOT NULL on every task row (ON DELETE CASCADE), and agents are workspace-scoped,
so GetAgentTaskInWorkspace (task JOIN agent ON workspace) is a single tenant
guard that works regardless of which optional source FK is set — including
orphan tasks whose autopilot_run_id was SET NULL after the autopilot was
deleted. Privacy layers on top: chat tasks stay creator-only, and every other
task mirrors the agent Activity / snapshot private-agent visibility gate via
canAccessPrivateAgent so the id-only endpoint is never more permissive than the
surface that exposes the task.

Tests cover run_only (same-ws success, cross-ws 404 no-mutation), quick_create,
retry clones, issue-task regression, chat non-creator 403, and private-agent
plain-member 403.

1195255e43 MUL-2771: feat(transcript): server-derived relative work_dir chip (#3428)
* MUL-2771: feat(transcript): server-derived relative work_dir chip

Adds a privacy-safe `relative_work_dir` field to the agent task wire
shape so the transcript dialog can show where a task ran without
leaking the user's home directory. Standard tasks strip the daemon's
workspaces root to `<wsUUID>/<taskShort>/workdir`; local_directory
tasks fall back to the trailing two path segments (`repos/foo`),
which keeps enough context for the user to recognise the directory
without exposing $HOME or the username.

The derivation lives in `taskToResponse` so every endpoint that
serves a task — list, snapshot, claim, rerun, cancel, complete,
fail — fills the field consistently. taskToResponse now also
populates `workspace_id`, which the prior shape declared but never
set. shortTaskID mirrors execenv.shortID; a colocated test pins the
two helpers together so future daemon-side layout changes don't
silently degrade the chip into the local_directory fallback.

Replaces the front-end stripping attempt in PR #3379, which passed
issue_id where workspace_id was required and therefore rendered the
full absolute path on every standard task.

Co-authored-by: multica-agent <github@multica.ai>

* MUL-2771: harden privacy guards on transcript work_dir chip

Address second-round review feedback from PR #3428:

1. Drop the `title={task.work_dir}` tooltip in the transcript dialog.
   The visible chip was safe but native browser tooltips re-rendered the
   absolute `/Users/<name>/...` on hover, leaking into screen shares,
   screenshots, and recordings — defeating the stated goal of the chip.
   The absolute path now never reaches the DOM (no title, aria, or data
   attribute).

2. Replace the "tail two segments" fallback for local_directory paths
   with explicit home-prefix stripping plus a basename-only final
   fallback. The old behaviour leaked the username on shallow paths like
   `/Users/alice/foo`, `/home/alice/project`, and `C:\Users\alice\foo`.
   The new behaviour recognises common per-user home layouts on macOS,
   Linux, and Windows (case-insensitive), strips them down to the
   remainder, and falls back to the basename for any path under an
   unrecognised root — a single segment can never carry the home prefix.

3. Align the Go and TypeScript field comments with the real fallback
   policy so future readers see "strip home / basename" instead of the
   outdated "tail two segments" description.

Tests: expanded `TestRelativeWorkDir` to cover shallow `/Users/...`,
`/home/...`, and `C:\Users\...` paths, the exact-home edge cases,
case-insensitive matching, and the non-home basename-only fallback.

1c91c2a3b2 security(db): scope DELETE/UpdateIssueStatus by workspace_id (defense-in-depth) (#3027)
* fix(security): scope DELETE/UpdateIssueStatus by workspace_id

Add workspace_id to the WHERE clause of DeleteIssue, DeleteComment,
DeleteProject, DeleteSkill, DeleteChatSession, and UpdateIssueStatus
as SQL-layer defense-in-depth.

Handler loaders (loadIssueForUser / loadSkillForUser / etc.) already
enforce workspace membership today, so this is not patching a known
live vuln. But the tenant invariant is currently a handler-layer
guarantee — a future loader bypass or a new caller skipping the
loader would be silently catastrophic. Making workspace_id part of
the SQL identity collapses the trust surface to the schema itself:
forging a sibling-workspace UUID becomes ErrNoRows instead of a
cross-tenant write.

Reference: incident #1661 (util.ParseUUID silent zero UUID returning
204 on a DELETE that matched zero rows) — same class of failure,
prevented at a different layer.

Scope:
- 5 DELETE queries: issue, comment, project, skill, chat_session
- 1 simple UPDATE: UpdateIssueStatus (2 narg, no SET ordering risk)
- All callers updated (handlers, service, runtime sweeper fallback)

Multi-narg UPDATE queries (UpdateIssue, UpdateProject, UpdateSkill,
UpdateComment, UpdateChatSession*) are deferred to a follow-up to
keep this change reviewable: each needs its narg pinning shifted
and per-caller verification.

sqlc was regenerated by hand (no local sqlc toolchain); CI's
backend job is the authoritative compile check.

* test(security): add workspace_scope_guard regression test

Locks in the SQL-layer tenant guard added in this PR. For each of the 6
scoped queries (DeleteIssue, DeleteComment, DeleteProject, DeleteSkill,
DeleteChatSession, UpdateIssueStatus), creates the resource in workspace
A, invokes the query with a foreign workspace UUID, and asserts the row
is untouched (0 rows affected with no error for :exec; pgx.ErrNoRows for
:one). A future refactor that drops the workspace_id arg from any of
these queries will now fail loudly instead of silently regressing.

Includes a sanity sub-test that the in-workspace path still mutates, so
a buggy guard that returns no-op for every call would not pass.

51aa924124 feat(chat): support renaming chat sessions inline (#2522)
Adds a pencil icon next to the trash icon on each session row in the chat
dropdown. Clicking it turns the title into an inline editable input:
Enter / blur saves, Escape cancels.

Server: new PATCH /api/chat/sessions/{id} handler that updates the title
via the existing `UpdateChatSessionTitle` sqlc query, broadcasts a new
`chat:session_updated` WS event so other tabs / devices stay in sync, and
rejects blank titles. Frontend mutation is optimistic with rollback,
matching the existing delete-session pattern.

* fix(chat): address PR #2445 review — test ctx, send gating, attachment surface

1. Backend test was 400ing because the handler reads workspace from
   middleware-injected ctx, and `newRequest` only sets the header. Helper
   `withChatTestWorkspaceCtx` mirrors the agent-access-test pattern and
   loads the member row + SetMemberContext before invoking the handler.

2. Attachment metadata now flows end-to-end:
   - new sqlc `ListAttachmentsByChatMessageIDs` (batch lookup, mirrors the
     comment-side query)
   - `chatMessageToResponse` takes `attachments` and `ChatMessageResponse`
     surfaces them — same shape as CommentResponse
   - `ListChatMessages` loads them via a new `groupChatMessageAttachments`
     helper so the chat bubble can render file cards
   - daemon claim path pulls `ListAttachmentsByChatMessage` for the latest
     user message and ships `ChatMessageAttachments` to the daemon
   - `buildChatPrompt` lists id+filename+content_type and instructs the
     agent to `multica attachment download <id>` — fixes the private-CDN
     expiring-URL problem where the markdown URL would have expired by
     the time the agent acts
   - TS `ChatMessage` gains an optional `attachments` field

3. Chat composer now blocks send while uploads are in flight:
   - `pendingUploads` counter increments in handleUpload, SubmitButton
     uses it to disable
   - handleSend also gates on `editorRef.current.hasActiveUploads()` to
     catch the Mod+Enter path that bypasses the button
   - new vitest covers the "drop large file → immediate send" scenario
     where attachment id would otherwise be silently dropped

b26f850d4e feat(agents): gate private-agent surfaces with allowed_principals predicate (#2359)
* feat(agents): gate private-agent surfaces with allowed_principals predicate

Tighten chat/@-mention, history, edit, and delete entry points so private
agents are only reachable by their owner or workspace owner/admin. Agent-to-
agent traffic still bypasses the gate so A2A collaboration keeps working.

- New canAccessPrivateAgent predicate in handler/agent_access.go; used by
  comment.enqueueMentionedAgentTasks (replacing the inline check), GetAgent,
  ListAgents (filter), ListAgentTasks, GetWorkspaceAgentRunCounts /
  Activity30d / TaskSnapshot (workspace-wide aggregations no longer leak
  private-agent existence + counts), chat.CreateChatSession,
  chat.SendChatMessage (re-checks on every send so role changes can't leave
  a stale session as a back-door), and autopilot.shouldSkipDispatch
  (caller = autopilot creator).
- allowed_principals is computed inline as {agent.owner_id} ∪ workspace
  owner/admin members. No new table — manual config is intentionally not
  exposed in v1; the predicate is the extension seam.
- Front-end agent detail page distinguishes 403 (private agent the caller
  can't access) from 404 (deleted/missing) and renders a "no access"
  placeholder with a back-to-agents button.
- Go tests cover the pure predicate matrix + the four protected surfaces;
  vitest passes for the affected views.

* feat(agents): gate issue assignment with the private-agent predicate

Refactor validateAssigneePair to call the shared canAccessPrivateAgent
helper. This closes the back door where a plain member could assign a
private agent to an issue and let normal task dispatch run it, side-
stepping the chat / @-mention gate. Agent callers (X-Agent-ID) bypass
so A2A delegation onto a private assignee still works.

Add an integration test covering all three callers (workspace owner,
agent owner, plain member).

Co-authored-by: multica-agent <github@multica.ai>

* fix(agents): close three private-agent gate bypasses found in PR review

1. X-Agent-ID forgery (resolveActor): require X-Task-ID alongside
   X-Agent-ID before trusting the agent identity. Without this a plain
   workspace member could set X-Agent-ID to any visible agent UUID and
   short-circuit the gate to "actor=agent, allow". Daemons already
   pair the two headers, so legitimate A2A traffic is unaffected.

2. Chat history read path (chat.go): GetChatSession / ListChatMessages /
   GetPendingChatTask / MarkChatSessionRead now go through a new
   gateChatSessionForUser helper that re-applies canAccessPrivateAgent
   after the ownership check, so a session creator whose role was later
   downgraded loses transcript access. ListChatSessions and
   ListPendingChatTasks filter their result sets by the same predicate.

3. Cross-workspace @mention (comment.enqueueMentionedAgentTasks):
   resolve the mentioned agent via GetAgentInWorkspace scoped to the
   issue's workspace so a UUID belonging to a different workspace's
   private agent can't slip past the gate (the gate was being applied
   against the current workspace's role table, which is the wrong
   one).

Regression tests cover each bypass, plus an update to the resolveActor
unit test to reflect the new "X-Agent-ID without X-Task-ID falls back
to member" contract.

Co-authored-by: multica-agent <github@multica.ai>

* test(handler): seed X-Task-ID alongside X-Agent-ID in existing agent-caller tests

After tightening resolveActor to require both headers (X-Agent-ID +
X-Task-ID) for the "agent" actor identity, three existing tests that
set only X-Agent-ID started failing because their requests now resolve
to "member" instead of "agent". Add createHandlerTestTaskForAgent
helper and seed a task per agent-caller assertion. Also patch
TestAgentExplicitMentionStillTriggers — it still passed only because
the @mention path doesn't care about author type for member callers,
but the test claims to exercise the agent path, so make it faithful.

Co-authored-by: multica-agent <github@multica.ai>

* test(handler): finish X-Task-ID seeding + fix cross-workspace mention test schema

The previous CI run still failed in two places:

1. server/cmd/server integration tests — postCommentAsAgent → authRequestWithAgent
   only set X-Agent-ID, so resolveActor downgraded the request to "member"
   and the on_comment chain produced the wrong task counts. Fix:
   authRequestWithAgent now also sets X-Task-ID, fetched or seeded by a new
   ensureAgentTask(agentID) helper.

2. TestMentionAgent_RejectsCrossWorkspaceAgentUUID's hand-crafted comment
   INSERT was missing comment.workspace_id, which migration 025 made
   NOT NULL. Pass testWorkspaceID into the seed row.

Build + vet clean locally; both packages compile.

60b215f44f feat(chat): support deleting chat sessions (#2115)
* feat(chat): support deleting chat sessions

Replaces the unreachable archive endpoint with a real hard delete and
exposes it from the chat history panel.

- DELETE /api/chat/sessions/{id} now hard-deletes the session and its
  messages (CASCADE), cancels any in-flight tasks before removal so the
  daemon doesn't keep running work whose result has nowhere to land,
  and broadcasts chat:session_deleted.
- Frontend adds a per-row delete button with a confirmation dialog,
  optimistically drops the session from both list caches, and clears the
  active session pointer locally + on other tabs via the WS handler.

* fix(chat): make session delete atomic and keep archived sessions read-only

Address review feedback on #2115.

- DeleteChatSession now runs lock + cancel + delete in a single tx and
  only broadcasts events post-commit. The new LockChatSessionForDelete
  query takes FOR UPDATE on chat_session, which blocks the FK validation
  of any concurrent SendChatMessage trying to enqueue a task for this
  session — that insert fails after we commit, so it can no longer
  produce an orphaned task whose chat_session_id is nulled by
  ON DELETE SET NULL. Cancel failure now aborts the delete instead of
  warn-and-continue.
- SendChatMessage refuses non-active sessions again. The archive code
  path is gone, but legacy rows with status='archived' may still exist
  in the DB; keep the guard until we explicitly migrate them.
- Frontend re-reads allChatSessionsOptions to disable ChatInput on
  legacy archived sessions so the UX matches the server-side guard.

4ad0a0b847 feat(chat): presence v4 — status pill, failure bubble, elapsed timing (#1856)
A complete UX upgrade for chat sending → receiving → recovering.

* StatusPill replaces the orphan spinner — stage-aware copy
  ("Reading files · 12s", "Searching the web · 14s", "Typing · 24s"),
  shimmer text, monotonic timer, derived effective status, > 60s
  warning tone, > 5min cancel button.

* WS writethrough on task:queued / task:dispatch / task:cancelled so
  pendingTask cache stays in sync with the daemon state machine without
  invalidate-refetch latency. broadcastTaskDispatch now includes
  chat_session_id when the task is for a chat session — the existing
  payload only carried it on the generic task: events, leaving the pill
  stuck at "Queued" until completion.

* Failure fallback — FailTask writes a chat_message tagged with
  failure_reason (mirrors the issue path's system comment, gated on
  retried==nil). Front-end renders an inline note ("Connection failed",
  with a Show details collapsible) instead of the previous black hole.

* Elapsed timing — chat_message.elapsed_ms persists task.completed_at -
  task.created_at on success/failure rows. UI shows "Replied in 38s" /
  "Failed after 12s" beneath assistant bubbles. Format helper shared
  between StatusPill and the persisted caption so the live timer and
  final reading never disagree.

* Optimistic burst rebalanced — pendingTask seed + created_at moved
  before the HTTP roundtrip so the pill appears the instant the user
  hits send; handleStop is fire-and-forget so cancel feels immediate
  (server confirmation arrives via task:cancelled WS).

* Presence integration — chat avatars use ActorAvatar (status dot +
  hover card); OfflineBanner above the input on offline/unstable;
  SessionDropdown shows per-row in-flight/unread pip plus a
  cross-session aggregate pip on the closed trigger.

* Editor blur on send so the caret stops competing with the StatusPill
  / streaming reply for the user's attention.

* Chat panel isOpen now persists globally; defaults to OPEN for new
  users (storage key absence) so the feature is discoverable. Existing
  users' prior choice is respected.

* DB: migrations 062 (failure_reason) + 063 (elapsed_ms), both
  ADD COLUMN NULL — fast, non-blocking, backwards compatible.

* WS: task:failed chat path now invalidates chatKeys.messages — fixes
  a pre-existing bug where the failure bubble required a page refresh
  to appear.

f628e48775 refactor(server): error-returning ParseUUID to prevent silent data loss
* refactor(server): make ParseUUID error-returning to prevent silent data loss (MUL-1410)

util.ParseUUID previously swallowed errors and returned a zero pgtype.UUID
on invalid input. When this zero UUID reached a write query (DELETE/UPDATE),
the SQL matched zero rows and the handler returned 2xx success — producing
silent data corruption. #1661 (DeleteIssue with identifier-style ID) was the
visible symptom; PR #1680 patched that one site, this commit closes the
class of bug.

Changes:

- util.ParseUUID now returns (pgtype.UUID, error). Add util.MustParseUUID
  for trusted round-trips that should panic on invalid input.
- handler/handler.go: parseUUID wrapper now calls MustParseUUID — any
  unguarded user-input string reaching it surfaces as a recovered panic
  (chi middleware.Recoverer → 500) instead of silently corrupting data.
  Add parseUUIDOrBadRequest(w, s, fieldName) for handler entry points.
- Convert every Queries.Delete*/Update* call site reachable from raw user
  input (autopilot, comment, project, skill, skill_file, label, pin,
  attachment, feedback, issue assignee, daemon runtime, workspace) to
  validate UUIDs explicitly with parseUUIDOrBadRequest, returning 400 on
  invalid input. Where a resolved entity.ID is already in scope, write
  queries now use it directly instead of re-parsing the URL string.
- Update getWorkspaceMember + loadIssueForUser to handle invalid UUIDs
  gracefully (404/400 instead of panic).
- Update util/middleware/cmd-level callers (subscriber_listeners,
  notification_listeners, activity_listeners, scope_authorizer,
  middleware/workspace) to use the error-returning API.
- Add server/internal/util/pgx_test.go covering valid/invalid input and
  the MustParseUUID panic contract.
- Add TestDeleteIssueByIdentifier + TestDeleteIssueRejectsInvalidUUID
  regression tests in handler_test.go (the original #1661 bug + the
  invalid-input case).
- Document the handler UUID parsing convention in CLAUDE.md so the rule
  is enforceable in future PR review.

* fix(server): address GPT-Boy review of #1748

P1 fixes from PR #1748 review:

1. Migrate remaining request-boundary UUIDs to parseUUIDOrBadRequest so
   malformed input returns 400 instead of panic/500. Was missing on:
   - issue.go: workspace_id in CreateIssue/ChildIssueProgress/ListIssues/
     SearchIssues/BatchUpdateIssues/BatchDeleteIssues; project_id /
     parent_issue_id / lead_id / assignee_id / assignee_ids / creator_id
     filters; batch issue_ids and assignee/parent/project fields in
     BatchUpdateIssues (skip on bad input via util.ParseUUID, matching
     the existing per-row continue semantics).
   - project.go: project id + workspace_id in GetProject/UpdateProject/
     DeleteProject; lead_id in CreateProject/UpdateProject;
     workspace_id in ListProjects + SearchProjects.
   - handler.go: resolveActor now uses util.ParseUUID for X-Agent-ID /
     X-Task-ID headers; invalid UUID falls back to "member" (matches
     pre-existing semantics) instead of panicking.
   - issue.go: validateAssigneePair returns 400 on invalid workspace_id
     instead of panicking.

2. Fix issue:deleted WS event payloads to emit uuidToString(issue.ID)
   instead of the raw URL string. After an identifier-path delete
   ("MUL-7"), the previous payload would have leaked the identifier to
   subscribers, leaving stale entries in frontend caches that key by
   UUID. Updated DeleteIssue (issue.go:1341) and BatchDeleteIssues
   (issue.go:1641). The slog "issue deleted" log line also now records
   the resolved UUID so logs match the WS payload.

3. Extend TestDeleteIssueByIdentifier to subscribe to the bus and
   assert issue:deleted.payload.issue_id is the resolved UUID, not
   the identifier.

* fix(server): validate remaining reviewed UUID inputs

* fix(server): validate remaining handler UUID inputs

* fix(server): finish request boundary UUID audit

* fix(server): validate remaining request body UUIDs

* fix(server): validate runtime path UUIDs

* fix(server): validate remaining audit UUID inputs

91424752ac feat(realtime): phase 0 — extract Broadcaster interface + add metrics (MUL-1138) (#1429)
* feat(realtime): phase 0 — extract Broadcaster interface + add metrics

Phase 0 of the WebSocket horizontal-scaling plan tracked in MUL-1138.
This change is intentionally behavior-preserving: it sets up the seams
needed for later phases (subscribe/unsubscribe protocol, scope-level
fanout, Redis Streams relay) without altering any wire protocol or
producer call sites.

What changed
- New realtime.Broadcaster interface covering the three fanout methods
  producers already use on *Hub (BroadcastToWorkspace, SendToUser,
  Broadcast). *Hub continues to satisfy it; a future Redis-backed
  implementation can be dropped in without touching listeners.
- registerListeners now depends on realtime.Broadcaster instead of
  *realtime.Hub, isolating the bus → realtime fanout layer behind an
  interface.
- New realtime.Metrics singleton with atomic counters: connects,
  disconnects, active connections, slow-client evictions, total
  messages sent/dropped, and per-event-type send counters. Wired into
  Hub register/unregister/broadcast paths and into every listener.
- New GET /health/realtime endpoint returning a JSON snapshot of the
  metrics so we can observe baseline fanout pressure before phase 1.

Why phase 0 first
GPT-Boy's only-Redis plan and CC-Girl's review both call out the same
prerequisite: get a Broadcaster seam and visibility in place before
introducing scope-level subscriptions or a Redis relay. Doing this as
a standalone step keeps each later PR focused and trivially revertable.

* feat(realtime): only-Redis fanout — scopes, subscribe protocol, Redis Streams relay (MUL-1138)

Implements the final-version plan agreed in MUL-1138 on top of phase 0:

* Hub: 4 scope types (workspace/user/task/chat), per-client subscription
  set, subscribe/unsubscribe WS frames, ScopeAuthorizer hook for
  task/chat scope auth, first/last-subscriber callbacks for the relay,
  workspace+user auto-subscribe on connect.
* RedisRelay: Broadcaster impl that XADDs every event into
  ws:scope:{type}:{id}:stream and XREADGROUPs only the scopes for which
  this node has live subscribers. Per-node consumer group, heartbeat,
  stale-consumer sweeper, MAXLEN cap, lag/disconnect metrics.
* Listeners: route task:* events to ScopeTask, chat:* events to
  ScopeChat; workspace remains the default for everything else.
* events.Event: optional TaskID / ChatSessionID hints so the listener
  layer can pick the right scope without re-parsing payloads.
* Handler: publishTask / publishChat helpers; chat + task message
  publishers updated to use them.
* main.go: when REDIS_URL is set, wrap the hub with NewRedisRelay and
  pass the relay (instead of the hub) to registerListeners. A
  db-backed ScopeAuthorizer enforces that task/chat subscribes belong
  to the caller's workspace.
* Metrics: per-scope subscribe/deny counters, redis connect state, node
  id, lag/dropped counters surfaced via /health/realtime.

Behavior in single-node mode (REDIS_URL unset) is unchanged.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* fix(realtime): address PR #1429 review must-fix items (MUL-1138)

- listeners: keep task/chat events on workspace fanout until the WS
  client supports scope-subscribe + reconnect-replay. Routing them
  through BroadcastToScope today (without any client subscriber) would
  silently drop every chat / task message and break the live timeline,
  chat unread badges, and pending-task UI. The server-side scope infra
  (Hub subscribe/unsubscribe, ScopeAuthorizer, Redis Streams relay)
  stays in place so flipping the switch in the client follow-up PR is
  a one-line change.

- scope_authorizer: ScopeChat now enforces CreatorID == userID, mirroring
  the HTTP layer (handler/chat.go: GetChatSession / SendChatMessage /
  MarkChatSessionRead). Without this, any workspace member who learned a
  session_id could subscribe to chat:message / chat:done /
  chat:session_read for a peer's private chat. The same creator-only
  check is applied to ScopeTask when the task is a chat task
  (task.ChatSessionID set). Issue tasks remain workspace-scoped.

- Refactor scope authorizer to depend on a narrow scopeAuthQuerier
  interface so its decisions can be unit-tested without a live DB.

- Add tests:
  * listeners_scope_test.go pins the workspace-fanout fallback for
    task:message / task:progress / chat:message / chat:done /
    chat:session_read.
  * scope_authorizer_test.go covers chat creator-only access, chat-task
    creator-only access, and issue-task workspace-only access (creator
    allowed, peer denied, cross-workspace denied, missing session
    denied, empty userID denied).

a744cd4f45 feat(chat): redesign state, header, and unread tracking
State management
- Pending task / live timeline are now Query-cache single source;
  Zustand mirror removed (fixes duplicate assistant render caused by
  the invalidate→refetch race window)
- WS subscriptions moved from ChatWindow to global useRealtimeSync so
  pending state survives minimize and refresh
- New GET /chat/sessions/:id/pending-task to recover live state on mount
- Drafts persisted per-session (was per-workspace)

Unread tracking
- Migration 040: chat_session.unread_since (event-driven; old chats
  stay clean — no mass backfill)
- POST /chat/sessions/:id/read clears unread; broadcasts
  chat:session_read so other devices sync
- New GET /chat/pending-tasks aggregate for the FAB
- ChatFab: brand-color impulse animation while running, brand-dot
  badge of unread session count
- ChatWindow auto-marks read when user is viewing the session

Header redesign
- Two independent dropdowns: agent (avatar + name + My/Others
  grouping) at the input bottom-left; session (title + agent avatar)
  in the header
- ⊕ new-chat button replaces the old + and history buttons
- Session dropdown lists all sessions across agents with avatars
- Empty state: 3 clickable starter prompts that send immediately
- Mention link renderer falls through to default span on null —
  fixes @member/@agent/@all silently disappearing app-wide
- User messages render through Markdown
- Enter submits in chat input only (with IME guard + codeBlock skip);
  bubble menu hidden in chat

Misc
- Partial index on agent_task_queue for fast pending-task lookup
- 2 new storage keys added to clearWorkspaceStorage
- useMarkChatSessionRead has onError rollback
- chat.* namespace logs across store, mutations, components, realtime
