7d2f20f2ee feat(chat): warn when agent daemon is too old for project context (#5867)
Chat project context (MUL-5150, #5765) is rendered into the run brief by the
daemon, so daemons older than the release that ships it silently drop the
project description while still honoring the server-extracted repos. Mirror
the handoff-note soft gate: resolve the active agent's runtime cli_version
from the warm runtime cache and, when it is a stale release build, surface a
warning next to the composer chip and inside the project submenu. Selection
is never blocked — dev-describe builds and unknown runtimes stay silent.

a3fe6d91dd MUL-5150: add project context to Chat (#5765)
* feat(chat): add project context

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

* fix(chat): resolve MUL-5150 review blockers

- Renumber project-context migrations to unique prefixes after current main:
  206_chat_session_project -> 212 (column), 207_chat_session_project_index ->
  213 (concurrent index). 206/207 collided with 206_agent_disabled_runtime_skills
  and main's 207-211 client_usage_daily set.
- Add the 4 missing chat input.project_context keys to ja/ko locales so the
  locale parity test passes (en/zh-Hans already had them).
- Lock the project-context control while a send is in flight (isSubmitting),
  not just while the agent is running. A brand-new chat creates its session
  lazily during send bound to the project at click time; switching project
  mid-send would create the session against the stale project and clear the
  editor as if the send landed on the new selection. Add a regression test.

* fix(chat): complete project context handling

* fix(chat): pin fresh chat to open session's agent on project switch

Switching an existing session to a different project opens a fresh chat but
only cleared the active session, dropping selection back to the stored
`selectedAgentId`. When that preference was stale (open session belongs to
agent B while the persisted pick is still agent A), the lazily-created session
and its first send bound to the wrong agent (agent A).

Extract the project-switch decision into a shared `planProjectContextChange`
pure helper in use-chat-controller.ts and route both chat surfaces (the chat
tab controller and the floating ChatWindow) through it, so the fresh chat is
pinned to the open session's agent and the rule cannot drift between the two
copies. Add a dual-entry regression test (pure-fn guard + controller
integration) covering the stale selectedAgentId case.

* chore(ci): re-trigger required checks on latest head

The prior push updated the branch ref but GitHub did not emit a pull_request
synchronize for it (PR head-sync lag), so CI/Mobile Verify never ran on the
commit carrying the stale-agent project-switch fix. Empty commit to force a
fresh synchronize on a head that includes it.

* fix(chat): renumber project migrations to 213/214 after main added 212

Current main added 212_agent_service_tier; the PR's 212/213 chat migrations
collided with it on the merge ref, failing TestMigrationNumericPrefixesStay
UniqueAfterLegacySet. Merge current main and move the chat column migration to
213 and the concurrent index migration to 214 (column before index preserved).

* fix(chat): lock ProjectPicker clear control during send (keyboard path)

The send-pending lock only put pointer-events-none on the wrapper, which
blocks the mouse but leaves ProjectPicker's inline clear button in the tab
order — a keyboard user could Tab to "Remove from project" and press Enter
mid-send, detaching the project after the lazily-created session already went
out with the old one (reopens the mid-send retarget path via keyboard).

Add an explicit `disabled` capability to the shared ProjectPicker that locks
the trigger, the menu (forced closed), and the inline clear button (disabled +
out of the tab order). Defaults to false, so issue/create/autopilot callers
keep their hover/keyboard clear. ChatInput passes disabled while the project
selection is locked.

Tests: real-ProjectPicker regression (keyboard activation of the clear control
is inert when disabled; still works when enabled) + ChatInput wiring assertion
that the picker is disabled mid-send.

c52ebeaa0f MUL-4864 fix(chat): use a single New Chat draft, keyed by session not agent (#5519)
* fix(chat): use a single New Chat draft, keyed by session not agent (MUL-4864)

An uncreated chat kept one draft per agent (`__new__:<agentId>`), so
switching the agent picker mid-compose swapped the draft out from under
the user and left invisible per-agent drafts behind. That slot shape was
never a product decision: it fell out of 34e452776, which keyed the
editor by agent to remount it and refresh the Tiptap placeholder. The
placeholder now syncs live, so the motive is gone — and mobile already
implements the target contract.

An uncreated chat now has ONE draft slot per workspace. `selectedAgentId`
is the send target, not draft ownership. Created sessions keep their own
per-session slots, so conversations stay isolated.

Three connected changes this needs to actually hold:

- Editor identity no longer tracks the agent. Keying it by agent kept the
  draft slot correct but still remounted on switch, dropping whatever the
  100ms draft debounce had not yet persisted — the last thing typed.
- The post-send "scrub the composer?" rule reads `activeSessionId` alone.
  Moving the picker is no longer navigation, so counting it as such left
  a completed send's text in the composer, primed to be sent a second
  time to the agent just picked. Both send chains (the chat tab's
  controller and the floating ChatWindow) now share one exported rule
  rather than two copies of the predicate.
- Legacy `__new__:<agentId>` slots are folded on load. They carry no
  timestamp, so when several exist none can be shown to be newest: adopt
  the persisted `selectedAgentId`'s slot (the draft the workspace would
  have opened with) and drop the rest — those extras are the invisible
  multi-draft state this removes. Text and attachments migrate together
  so a draft can't end up with another agent's files.

Tests cover the acceptance scenarios: agent switch preserves text,
attachments and the live editor instance; sessions stay isolated; the
first send clears the draft and routes to the agent selected at send
time; a failed create keeps the input; and the migration adopts, prunes,
persists, and is idempotent.

* fix(chat): file unflushed keystrokes under the draft they were typed in (MUL-4864)

Review blocker: one editor instance serves every chat draft and its
onUpdate is debounced 100ms. Typing in session A and switching to B
inside that window fires the timer with B's draftKey in scope — because
onUpdate always resolves to the latest render's closure — writing A's
document into B's draft. Worse, ContentEditor's dirty guard suppresses
B's incoming sync while those unflushed bytes are live, so B's own draft
never loads and A's context could be sent to B's agent.

This predates the per-agent draft change: on main `editorKey` is
`selectedAgentId`, so any two sessions of the SAME agent already shared
one editor instance and already cross-wrote. Verified by running the new
regression against main's editor identity with the flush removed — it
fails there too. Unifying the New Chat draft widened the same hazard to
cross-agent switches, so it is fixed here rather than left latent.

Fix at the root: a debounced write must land on the key it was typed
under, not wherever the composer now points.

- ContentEditor gains `flushPendingUpdate()`: cancels the armed debounce
  and hands its markdown back rather than firing it, and advances the
  emit watermark so the editor reads clean and the dirty guard stops
  blocking the incoming sync. Distinct from flushPendingOnUnmount — the
  instance is alive, so it reads the live document.
- ChatInput flushes on draftKey change and commits the result to the
  PREVIOUS key. useLayoutEffect, not useEffect: passive effects run
  child-first, so a passive flush would land after ContentEditor's sync
  had already skipped on a dirty editor; a layout effect is part of the
  commit, so no pending timer can fire ahead of it.
- onUpdate and the flush now share one `commitDraft`, so text and
  attachment pruning cannot diverge between the two paths.

Tests exercise the REAL debounce and REAL dirty guard, not an instant
mock onUpdate:

- chat-input-draft-isolation.test.tsx (new): mounts the real
  ContentEditor with only Tiptap's primitive mocked. Pins A/B isolation
  across a mid-debounce switch, that B's draft actually loads, that a
  lazy session create keeps its bytes in the New Chat slot, and that an
  agent switch still preserves the New Chat draft. Three of four fail
  without the flush.
- content-editor.test.tsx: flushPendingUpdate hands back the pending
  markdown, kills the timer, unblocks the next sync, and leaves the
  guard intact when NOT flushed.

* fix(chat): keep an in-flight upload bound to the draft it started in (MUL-4864)

Second review blocker. An upload PINS the editor to its source document:
Guard 0 refuses to setContent over an `uploading` node, because wiping it
strands the upload's finalize and the file silently vanishes. So while an
upload runs, the instance still holds A's document even though the user
has navigated to B — and the upload's own completion dispatch fires
onUpdate on that instance, which resolves to the latest render's closure.
Result: A's body and its attachment URL were written into B's draft, B's
own draft was destroyed, and A lost the upload it was waiting for.

Nothing stopped this: useUploadGate gates submit, not session/agent
navigation. Reproduced as a test before fixing — B's "B's own words" was
replaced by A's body + A's CDN URL.

Root cause is the same shape as the debounce bug, one level up: the
editor's writes were keyed off what is SELECTED, when they belong to what
is LOADED. Those are the same key except while an upload pins the
document.

- chat-input models that explicitly with `editorDraftKeyRef` — the draft
  whose document the instance holds. Every editor-driven write (onUpdate,
  the upload's attachment binding) uses it, not `draftKey`.
- The draft switch defers while `hasActiveUploads()`, leaving both the
  document and its writes on the source key, then completes when the gate
  clears. Blocking navigation instead would make the user wait on a
  network round-trip to change tabs.
- The deferred case must force the adopt: ContentEditor's sync effect
  CONSUMED the defaultValue change while Guard 0 was up
  (lastDefaultValueRef advances before the guard), so it never re-runs and
  B's draft would never load. New `adoptContent()` ref method lands it;
  its body is the sync effect's own apply path, extracted so both agree.
- handleSend refuses while loaded !== selected. The upload gate covers
  most of that window but not the sliver between the upload's final
  dispatch and the adopt re-render — React flushes that on a scheduler
  task, so Mod+Enter can land first.

Tests (real ContentEditor, real Guard 0, real debounce, real upload
lifecycle incl. the transaction that publishes the queue flip):
completing upload's markdown stays in the source draft and never reaches
the target; an attachment dropped while pinned binds to the source; the
target draft loads once the guard clears; send is refused mid-divergence.
Each verified to fail without its fix — the send guard initially passed
vacuously (the disabled SubmitButton swallowed the click) and now drives
the real Mod+Enter path.

3b08456264 feat(views): block draft-fixing actions while attachments upload (#5465)
Submitting a composer mid-upload silently lost the file: the editor holds a
`blob:` placeholder that gets stripped during serialization, and the
attachment id does not exist yet, so the send succeeded without the file.
Chat and Quick Create gated this; manual issue create, Feedback's button,
comments, replies and comment edit did not.

Gate every action that FIXES a draft — Send/Create/Save, Cmd/Ctrl+Enter,
Enter on the title, and the manual/agent mode switches — behind one source
of truth: the editor document, which IS the upload queue. ContentEditor
publishes queue transitions via `onUploadingChange` (a transaction listener,
not `onUpdate` — that path is debounced and skips no-change emissions, and a
failed upload leaves byte-identical markdown, so the un-gate would never
fire). `useUploadGate` pairs that render state with an `isBlocked()` re-read
at submit time, since the shortcut paths never consult the button.

The publisher emits its current answer on subscribe rather than only on
flips: hosts outlive editor instances (comment edit remounts on cancel,
chat swaps by key on agent switch), and an editor torn down mid-upload would
otherwise leave submit wedged shut with no pending node left to reopen it.

Also fixes the failure toast that never fired: `uploadWithToast` only
reported errors if a caller passed `onError`, and none did, so failed uploads
removed their placeholder and vanished unexplained. `useEditorUpload` now
supplies it once for every composer.

Per MUL-4808: drops Quick Create's upload-time lock on the attach button
(files can queue), and leaves description autosave ungated by design.

4fac8d772f feat(attribution): Human Attribution Phase 1 (MUL-4302) (#5150)
* feat(attribution): Phase 1 foundation — provenance schema + resolver (MUL-4302)

Human Attribution, Phase 1 (地基) first increment. Every agent run must be
traceable to exactly one accountable human AND record at which waterfall level
that human was resolved, so a NULL originator can be told apart from a genuine
'no human in the chain'.

- migration 149: add originator_source (waterfall label) + delegation/retry/
  rerun/rule-version lineage + kind-tagged trigger evidence to agent_task_queue.
  No FK, no cascade, no CHECK on the source enum (MUL-4302 §7); nullable ADD
  COLUMNs = fast metadata-only change on the hot queue table.
- internal/attribution: the accountable-human vocabulary (Source, EvidenceKind,
  TriggerKind) + pure, unit-tested classification rules (ClassifyComment/
  ClassifyDirect). No DB, no authorization — provenance labeling only.
- service: attributionFor{IssueTask,TriggerComment} gather facts and delegate to
  the pure classifier; the legacy originator resolvers now delegate here so
  there is one source of truth. originator_user_id's VALUE is unchanged, so the
  Composio-overlay and canInvokeAgent A2A authorization boundaries are
  byte-for-byte preserved (MUL-4302 §1.3).
- enqueueIssueTask / enqueueMentionTask stamp originator_source + evidence;
  CreateRetryTask carries the parent attribution forward and records
  retry_of_task_id so retry and manual rerun stay separable (MUL-4302 §5).

Verified: go build ./..., go vet, gofmt clean; new attribution unit tests +
enqueue stamping integration test green; existing resolve_originator tests
unchanged.

* feat(attribution): split accountable_user_id from originator, close enqueue bypasses (MUL-4302)

Phase 1, per Bohan's decision on the MUL-4302 thread: audit and authorization
answer different questions and get different columns.

- Migration 151 adds agent_task_queue.accountable_user_id (no FK, no cascade).
  Authorization keeps reading ONLY originator_user_id (canInvokeAgent A2A gate,
  Composio overlay); audit/UI/usage read accountable_user_id + source + evidence.
- Invariant (finalizeAttribution, single chokepoint + §11 tests): originator
  non-null ⟹ accountable equals it. The two diverge only when originator is null
  (autopilot / degraded fallback), which is the deferred rule_owner/owner_fallback
  increment; this lands the column + mirror-write so that split has a home.

- Close the NULL-source enqueue bypasses Elon flagged: chat, quick-create,
  deferred-fallback and run_only-autopilot now stamp originator_source + evidence
  (+ accountable where a human exists). Autopilot stays unattributed until the
  rule-version snapshot table lands, but is no longer a silent NULL-source row.
  Retry inherits accountable_user_id like the rest of the attribution lineage.

- Fix assign/promote attribution (§4): a member who assigns/promotes an existing
  issue is now the accountable human (and, by the invariant, originator) ahead of
  the issue creator. Threaded as an OPTIONAL actor override, so comment/rerun/
  autopilot paths keep today's resolution and create-with-assignee (creator ==
  actor) is unchanged. The squad leader gate already judged the same member.

Also merges origin/main: renumbers the attribution migration 149→150 (main took
149 for issue_origin_agent_create) and folds agent_create into ClassifyDirect's
origin inheritance.

go build/vet/gofmt clean; attribution unit tests + service stamp/actor tests +
handler suite pass on a fresh DB migrated through 151.

* docs(attribution): fix accountable NULL semantics + close chat/quick-create evidence boundary (MUL-4302)

Addresses Elon's 2nd-round review on PR #5150 (pre-merge doc/evidence items):

- Migration 151 no longer overclaims NULL. accountable_user_id is NULL not only
  on pre-migration rows but on NEW rows whose audit source resolved no human yet
  (run_only autopilot writes originator_source='unattributed' with NULL
  accountable until rule_owner lands). Header + COMMENT ON COLUMN reworded so a
  schema reader does not misjudge the invariant.

- Chat now uses the UNIFORM evidence pair (kind=chat, ref=chat_session_id), like
  autopilot_run/issue_assignment, instead of relying only on the dedicated
  chat_session_id column — new EvidenceChat kind. Added a service test asserting
  chat stamps direct_human + chat evidence.

- Quick-create is documented as the ONE intentional no-antecedent-row path: no
  comment/issue/session/run exists at enqueue time (the run creates the issue), so
  trigger_evidence_kind/ref stay NULL while the human rides originator/accountable
  and source is direct_human — not a NULL-source bypass.

No authorization behavior change. attribution + service + handler suites pass on a
DB migrated through 151.

* chore(attribution): renumber migrations 150/151 → 157/158 after merging main (MUL-4302)

main's #5162 ("unblock release migrations") renumbered the chat migrations and
took 150 (agent_task_coalesced_comments) and 151 (chat_read_cursor), colliding
with this branch's attribution migrations. Renumber them above main's new highest
(156) so TestMigrationNumericPrefixesStayUniqueAfterLegacySet passes:

- 150_agent_task_attribution      → 157_agent_task_attribution
- 151_agent_task_accountable_user → 158_agent_task_accountable_user

Fixed the internal "migration 150" references in 158's header to 157. Migrations
apply cleanly through 158 on a fresh DB; migration lint green.

* feat(attribution): autopilot rule_owner — accountable = rule version publisher (MUL-4302)

Implements rule_owner (MUL-4302 §3.4), the first attribution source where the
accountable human diverges from the (NULL) authorization originator.

- Migration 159 adds the append-only autopilot_rule_version snapshot table (no FK,
  no cascade); migration 160 adds its CONCURRENTLY lookup index.
- Write-on-publish: CreateAutopilot appends v1 (publisher = creator); UpdateAutopilot
  appends a new version when a SUBSTANTIVE autopilot-row field changes (assignee /
  status / execution_mode) — cosmetic edits (title/description/template) write none.
  Both run inside the existing handler tx (atomic with the autopilot write).
- Dispatch resolution: both autopilot execution modes now resolve the active rule
  version and stamp originator_source='rule_owner', accountable_user_id=publisher,
  rule_version_id=<snapshot>, with originator_user_id left NULL (authorization
  unchanged). run_only stamps CreateAutopilotTask directly; create_issue resolves in
  attributionForIssueTask so both modes attribute identically. A missing version /
  non-member publisher degrades to unattributed — never fabricates a human.
- finalizeAttribution now enforces the invariant ONE-WAY: it mirrors originator onto
  accountable only when originator is valid, leaving an explicitly-set accountable
  (rule_owner / future owner_fallback) intact when originator is NULL. Added
  rule_version_id to CreateAgentTask so the create_issue path persists it too.

Also merges origin/main and renumbers this branch's attribution migrations
150/151 → 157/158 (main's #5162 took 150/151); rule_version table is 159/160.

Tests: attribution unit RuleOwner + one-way invariant table; service integration
tests proving an autopilot-origin issue stamps rule_owner + rule_version_id (and
degrades to unattributed with no version). Full service/attribution/handler/
migration suites pass on a DB migrated through 160; build/vet/gofmt clean.

Deferred (same PR): trigger-table republish (cron/webhook/event_filters) and
system-pause/archive versioning; owner_fallback + fail-closed; manual rerun.

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

* fix(attribution): manual autopilot trigger → direct_human to the triggering member (MUL-4302)

Elon's blocking finding: a member manually triggering an autopilot was attributed
rule_owner (accountable = rule publisher, originator NULL) like a schedule/webhook
run, so member B triggering member A's autopilot landed accountable=A and carried
no originator authorization context for the run. Per MUL-4302 §4 a manual "run now"
is a direct human action and must attribute direct_human to the triggering member.

- Thread the triggering member from TriggerAutopilot into dispatch: new
  DispatchAutopilotManual carries actorUserID (resolved via resolveActor +
  memberActorUserID, so only a member actor is a human; an A2A agent actor falls
  back to rule_owner). DispatchAutopilot / DispatchAutopilotForPlan keep their
  public signatures (pass an invalid actor); only the internal dispatchAutopilot /
  dispatchCreateIssue / dispatchRunOnly gained the param, so the many existing
  callers are untouched.
- run_only: dispatchRunOnly stamps direct_human (originator == accountable ==
  actor, no rule_version) for a manual actor, else rule_owner. CreateAutopilotTask
  gains an originator_user_id param for the manual case.
- create_issue: dispatchCreateIssue enqueues a manual trigger via the actor-carrying
  *WithHandoff entry points; attributionForIssueTask's autopilot-origin rule_owner
  branch is now guarded on !actorUserID.Valid, so a valid actor falls through to the
  direct_human override. Both execution modes attribute identically.
- schedule / webhook keep rule_owner (no actor). Trigger-table + system-pause/archive
  versioning remain the pre-merge follow-ups.

Tests: the run_only row assertion Elon asked for (schedule → rule_owner row on
CreateAutopilotTask), plus manual direct_human on BOTH modes (run_only and
create_issue), including a manual actor distinct from the rule publisher. Full
service/attribution/handler/migration/scheduler/cmd suites pass on a DB migrated
through 160; build/vet/gofmt clean.

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

* feat(attribution): owner_fallback + fail-closed policy, and manual-rerun direct_human (MUL-4302)

Two of the three remaining Phase 1 items (trigger-table / system-pause versioning
is deferred — see PR description).

owner_fallback + fail-closed (§1/§3.5) — the never-null accountable guarantee:
- attribution.OwnerFallback degrades an UNATTRIBUTED result to owner_fallback:
  accountable = agent owner, originator stays NULL (audit-only, authz untouched),
  Source.Precise()==false. finalizeAttribution's one-way invariant already allows
  accountable-set / originator-NULL divergence, so nothing else changes.
- Migration 161 adds workspace.attribution_fail_closed (default FALSE) + a lean
  GetWorkspaceAttributionFailClosed read. (Also added the column to ListWorkspaces'
  explicit column list so its row type stays db.Workspace.)
- applyAttributionFallback is applied at every enqueue boundary (issue, mention,
  chat, quick-create, deferred-fallback, autopilot run_only): unattributed →
  owner_fallback (agent owner) by default, or ErrAttributionFailClosed when the
  workspace is fail-closed, which the caller surfaces to refuse the enqueue (the
  run does not start). So no run is left without an accountable human, and a
  compliance workspace can block unattributable runs instead.

manual rerun (§5) — a rerun is a NEW direct_human trigger to the rerunning member:
- RerunIssue threads the acting member (resolved in the handler via resolveActor)
  down to enqueueRerunTask, and attributionForIssueTask is now actor-first so the
  actor wins over an INHERITED trigger comment (a rerun keeps the comment for the
  daemon's prompt context but must attribute to whoever clicked rerun, not the
  original comment's human).
- rerun_of_task_id lineage is recorded via a targeted SetAgentTaskRerunOf update on
  the rerun path only (keeping the shared CreateAgentTask insert untouched), so
  system retry (retry_of_task_id) and human rerun stay separable in reporting.

Tests: OwnerFallback unit test; owner_fallback + fail-closed-refusal + manual-rerun
(direct_human + rerun_of_task_id) service tests; the prior "degrades to unattributed"
test updated to owner_fallback. Full service/attribution/handler/migration/scheduler/
cmd suites pass on a DB migrated through 161; build/vet/gofmt clean.

* fix(attribution): close fail-open holes + move rerun_of_task_id into creation snapshot (MUL-4302)

Addresses Elon's two must-fixes on PR #5150.

1. accountable-never-null / fail-closed had fail-open holes. applyAttributionFallback
   now, for an UNATTRIBUTED run, refuses the enqueue (ErrAttributionFailClosed) in
   THREE cases instead of silently degrading to a runnable NULL-accountable task:
   - workspace policy read fails (or no workspace) → fail closed; we cannot confirm
     fallback is permitted, so we don't run an unattributable task on a DB hiccup.
     (Only the rare unattributed path pays this; precise runs never read the policy.)
   - workspace is fail-closed → refuse (unchanged).
   - owner_fallback has no valid agent owner → refuse rather than enqueue a task with
     a NULL accountable_user_id.
   ErrAttributionFailClosed's doc now covers all three "cannot guarantee an
   accountable human" refusals. Added missing-owner / policy-read-failure /
   precise-passthrough tests.

2. manual rerun rerun_of_task_id was a post-notify UPDATE (race: the queued event /
   daemon claim could see rerun_of_task_id = NULL, and a failed update degraded the
   run to a plain direct_human). It now rides the CreateAgentTask insert — threaded
   through enqueueIssueTask / enqueueMentionTask as a creation param (like
   retry_of_task_id) so it is written in the same statement before the daemon is
   notified. Removed the SetAgentTaskRerunOf follow-up query.

Also merges origin/main (unrelated CLI fix #5167, no conflict). Full service /
attribution / handler / migration / scheduler / cmd suites pass on a DB migrated
through 161; build / vet / gofmt clean.

* feat(attribution): rule_owner versioning on trigger edits + system-pause/archive (MUL-4302)

The final remaining Phase 1 item: substantive publishes beyond the autopilot row now
republish the rule version, so a run's rule_owner accountable follows whoever last
changed what the rule does.

- Extracted the config-summary + insert into service.RecordAutopilotRuleVersion so
  the handler and the (different-package) failure monitor share one writer; the
  handler's recordAutopilotRuleVersion is now a thin wrapper.
- Trigger edits: UpdateAutopilotTrigger and DeleteAutopilotTrigger republish the rule
  version with the acting member as publisher, ATOMICALLY (tx-wrapped mutation +
  version write, mirroring CreateAutopilot/UpdateAutopilot). CreateAutopilotTrigger
  republishes best-effort — the webhook path mints its token with a retry loop that
  cannot share one tx, and a create is usually initial setup already covered by v1;
  a failed write there is benign (active version stays the current publisher, the new
  trigger fires under it, no immediate daemon claim rides it).
- Archive (DeleteAutopilot) republishes (member, status=archived), tx-wrapped.
- System auto-pause (failure monitor) republishes with a 'system' publisher,
  best-effort — a background sweep to a non-dispatching state (a paused autopilot
  never dispatches; a later member resume supersedes).
- RotateWebhookToken / SetSigningSecret deliberately do NOT version: they rotate
  credentials, not the rule's behavior (not §3.4 substantive).

Semantics: a system-published (no-member) active version degrades dispatch to
unattributed → owner_fallback, never fabricating a human.

Tests: republish-reattributes (member A → member B supersedes → dispatch resolves to
B; system publisher → unattributed). Full service/attribution/handler/migration/
scheduler/cmd suites pass on a DB migrated through 161; build/vet/gofmt clean.
Also merges origin/main (unrelated frontend feature #5074).

* fix(attribution): make trigger-create rule-version republish atomic (MUL-4302)

Addresses Elon's final Phase 1 blocking finding: CreateAutopilotTrigger recorded the
rule-version republish best-effort AFTER the trigger insert. If member B added a
schedule/webhook trigger to member A's autopilot and the version write failed, future
schedule/webhook dispatches would keep attributing to A — violating the rule_owner
invariant that the last member to substantively change the rule owns future runs
("no immediate daemon claim" doesn't save it, since the miss surfaces at the LATER
trigger firing).

Both create paths now write the version in the SAME tx as the trigger INSERT:
- schedule create: wrap CreateAutopilotTrigger + recordAutopilotRuleVersion in one tx.
- webhook create: each mint-with-retry attempt runs in its own tx (insert + version
  commit together; a token collision rolls that attempt back and retries with a fresh
  token; a version-write failure rolls the trigger back). Passes ap + the acting
  member id into the helper.
- removed the best-effort recordTriggerRuleVersionBestEffort helper (and the now-unused
  slog import).

Test: TestCreateTrigger_RepublishesRuleVersionAtomically drives both create paths
through the handler and asserts a rule version is published by the acting member.
Existing webhook/trigger/archive handler tests still pass. Also merges origin/main
(unrelated avatar feature #5074). Full service/attribution/handler/migration/
scheduler/cmd suites pass on a DB migrated through 161; build/vet/gofmt clean.

* feat(attribution): Phase 2.1 — surface run attribution on the task API (MUL-4302 §9)

First Phase 2 (visibility) increment: the agent-task API now returns the resolved
accountable-human provenance so the UI can render an "on behalf of" badge.

- AgentTaskResponse gains an `attribution` object: source label (never blank —
  pre-migration NULL renders "unattributed") + `precise` flag (false for the degraded
  owner_fallback / backfill / unattributed sources), the initiator (accountable) and
  originator (authorization) user refs, the evidence {kind, ref_id} pointer, and the
  rule_version / delegated / retry / rerun lineage ids.
- The label + evidence + raw ids are built in the PURE taskToResponse (no DB), so
  every task response carries them. Names are hydrated separately, only on the
  user-facing surfaces (ListAgentTasks, ListWorkspaceAgentTaskSnapshot, RerunIssue,
  CancelTaskByUser) — daemon-claim paths stay lean.
- Hydration resolves initiator/originator from the GLOBAL user table (departed-member
  safe) via a new batch GetUsersByIDs query (no N+1); best-effort, so a lookup hiccup
  leaves the raw ids intact.

Tests: pure taskAttributionBase (direct_human / rule_owner NULL-originator /
owner_fallback degraded / pre-migration→unattributed) + DB hydration (fills known
ref, leaves unknown id un-filled, skips nil). Full handler/service/attribution/
migration/scheduler/cmd suites pass on a DB migrated through 161; build/vet/gofmt
clean. The field is additive — the frontend's parseWithFallback ignores unknown keys,
so nothing breaks until the UI increment consumes it.

Also merges origin/main (unrelated editor feature #5090).

Remaining Phase 2 (next increments, same PR): frontend zod schema + "on behalf of"
badge + evidence-chain jump; append-only correction events (write + display).

* feat(attribution): Phase 2.2 — on-behalf-of badge in the execution log (MUL-4302 §9)

Surface the accountable human on every agent run row:
- AttributionBadge composes Badge + ActorAvatar, shows "on behalf of <member>"
  with the resolution source as a tooltip; degraded (non-precise) attribution
  gets a warning tone, and an unresolved initiator renders an explicit
  "no responsible member" chip.
- Wire the badge into both active and past rows of the execution log.
- Mirror the attribution shape into AgentTaskResponseSchema (defensive, .loose())
  so the cancel-task path carries it through zod; add parse tests.
- Export TaskAttribution/AttributionUser/TaskEvidence from @multica/core/types
  and add the attribution block to all four issues.json locales.

* fix(attribution): hydrate initiator names on issue-facing task endpoints + bound the badge (MUL-4302 §9)

Address Elon's PR #5150 review:
- ListTasksByIssue (the execution-log data source), GetActiveTaskForIssue and the
  issue-scoped CancelTask now call hydrateTaskAttributions, so the "on behalf of
  <member>" badge shows the real member name on issue detail instead of falling
  back to "someone". Mirrors the existing ListAgentTasks / snapshot behavior.
- AttributionBadge: cap width (max-w-40, min-w-0) and truncate the name span so a
  long name / narrow right column can't squeeze out trigger/status/actions; keep
  the avatar shrink-0.
- Add a handler test asserting the issue task list returns a hydrated
  attribution.initiator.name.

* fix(attribution): use semantic AvatarSize 'xs' for the badge avatar

main refactored ActorAvatar.size from a raw pixel number to the semantic

* fix(attribution): stage-cascade falls back to parent-issue provenance, not agent owner (MUL-4302)

When closing the last sub-issue in a Stage wakes the parent's assignee agent, the
run was enqueued via a system-authored child-done comment with no actor, which the
resolver classified as unattributed and then degraded to owner_fallback (the agent's
own owner). That is the wrong accountable human: the woken run should be accountable
to whoever caused the parent issue to exist.

attributionForIssueTask now detects a system-authored trigger comment and falls
through to the parent issue's own provenance — the same creator / agent_create-origin
/ autopilot-origin chain a direct enqueue resolves (so an agent-decomposed parent
attributes via delegation to the human who drove it; a member-created parent to that
member; an autopilot parent to the rule publisher). owner_fallback is now only the
last resort when the parent provenance itself has no human.

- Extract attributionFromComment so attributionForIssueTask can inspect author_type
  without a second GetComment; authorization resolution stays byte-identical.
- Add a DB-backed test asserting a system child-done comment resolves to the parent
  issue's origin human (delegation), not owner_fallback.

* feat(attribution): autopilot runs attribute to the firing trigger's creator (MUL-4302)

Per Bohan: an autopilot schedule/webhook run should be accountable to the human
who created the SPECIFIC trigger that fired it, not the rule publisher. (Manual
triggers already attribute to the invoking member via direct_human — unchanged.)

- Migration 162: add autopilot_trigger.created_by_type/created_by_id (nullable, no
  FK/cascade). Capture the creating member at both trigger-create sites (schedule +
  webhook).
- New precise source trigger_owner: originator stays NULL (an autonomous fire
  carries no human authorization — same authz-safe divergence as rule_owner),
  accountable = the trigger's member creator.
- triggerOwnerAttribution resolves run.trigger_id → creator; wired into run_only
  dispatch and the create_issue path (bridging issue → active run → trigger_id).
  Legacy triggers with no recorded creator, and agent-created triggers, degrade to
  rule_owner then owner_fallback — nothing regresses.
- Frontend: trigger_owner source label in all four locales + badge switch case.
- Tests: attribution TriggerOwner unit + Precise/invariant; DB-backed resolver
  tests (member creator → trigger_owner; creatorless → rule_owner fallback).

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

* fix(attribution): mirror accountable_user_id on comment-coalescing merge (MUL-4302)

The one-way invariant is 'originator_user_id IS NOT NULL ⟹ accountable_user_id =
originator_user_id', enforced at finalizeAttribution for enqueues and preserved by
the retry-clone (copies both columns). But MergeCommentIntoPendingTask (main #5192)
re-stamps originator_user_id to the newly-coalesced comment's human WITHOUT touching
accountable_user_id — so folding member B's comment into member A's queued task left
originator=B / accountable=A, violating the invariant. Re-stamp accountable to mirror
the new originator (same thing finalizeAttribution does). Add a DB-backed regression
test.

* fix(attribution): Elon's 3 must-fixes + DB cross-column invariant CHECK (MUL-4302)

Bohan approved Elon's plan; this closes the three attribution boundaries he flagged
and locks the one-way invariant at the DB.

1. Delegation now inherits the parent's ACCOUNTABLE, not just its originator. An
   autopilot-rooted chain (parent originator NULL, accountable = trigger creator)
   @mentioning an agent / creating a sub-issue used to drop to unattributed →
   owner_fallback and fail-closed workspaces wrongly rejected the fan-out. Added
   ParentAccountable/OriginAccountable to CommentFacts/DirectFacts; ClassifyComment/
   ClassifyDirect copy accountable down (source=delegation, precise, originator NULL)
   so the chain root stays stable at any depth (§3.2).
2. The direct-chat send path (SendDirectChatMessage, MUL-4351) wrote only
   originator_user_id — no accountable/source/evidence, a NULL-source bypass. It now
   stamps the full direct_human attribution like EnqueueChatTask.
3. Comment-coalescing merge re-attribution is now ATOMIC: MergeCommentIntoPendingTask
   re-stamps the whole snapshot (person columns + source + delegation lineage + rule
   version + evidence) of the new comment, not just the two person fields, so a merged
   run never shows B accountable while pointing at A's stale source/evidence.
4. Migration 169: NOT VALID CHECK (originator_user_id IS NULL OR (accountable_user_id
   IS NOT NULL AND accountable_user_id = originator_user_id)). Enforces the invariant
   on every new write (the class of bug #5192 introduced); historical rows not blocked,
   VALIDATE after Phase 3 backfill. Updated test fixtures that seeded originator-only
   rows to also set accountable.

Merged latest main (renumbered attribution migrations 163–168 after main took 161/162;
merged the retry-clone chat_input_task_id + attribution columns). Verified: go build/
vet, attribution/service/handler/cmd-server tests on a migrated DB, frontend
typecheck/lint/tests.

* fix(attribution): trigger responsibility transfers to effective publisher; fail-closed comment merge

Elon final-review must-fix 1 (MUL-4302): trigger_owner now resolves to the
member CURRENTLY responsible for the firing trigger's effective config, not the
fixed creator. Per-trigger published_by on autopilot_trigger, seeded to the
creator and re-stamped to the editor on a substantive edit — a trigger-scoped
edit bumps only that row (UpdateAutopilotTrigger), an autopilot-level edit bumps
all its triggers (UpdateAutopilot). Editing one trigger never reassigns another.
Adds real dispatchRunOnly transfer test + resolver-level isolation test.

Must-fix 3: AttributionForMergedComment reuses applyAttributionFallback and
returns ErrAttributionFailClosed; the merge caller refuses on fail-closed,
keeping the queued task's original precise snapshot instead of degrading it to
owner_fallback. Adds regression test.

Renumbered attribution migrations to 166-172 after merging main.

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

* fix(attribution): make migration 172 invariant CHECK upgrade-safe (Option A)

Elon final-review must-fix 2 (MUL-4302), rollout chosen by Bohan. The NOT VALID
CHECK still checks a pre-existing row on any later UPDATE (even one not touching
attribution columns), so cross-deployment stale queued/running tasks (originator
set, accountable NULL from before migration 167) would fail on their next
claim/complete/cancel. Exempt exactly those legacy rows via 'originator_source
IS NULL' — that column was added in 166 with no backfill, so it is NULL only on
pre-migration rows and non-NULL on every attribution-aware write. New writes
stay fully enforced; the #5192 bypass class (source always set) is unaffected.
Phase 3 backfills legacy rows then drops+re-adds the strict form + VALIDATE.

Adds TestAttributionInvariantCheck_ExemptsLegacyRows (legacy row survives a
status UPDATE) and updates the reject-bypass test to the enforced regime.

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

* fix(attribution): pin substantive/cosmetic edit boundary for trigger transfer

Elon re-review must-fix 1: an autopilot-level edit only transfers trigger_owner
responsibility when it changes what the automation instructs or who/whether it
runs. autopilotRuleSubstantiveChange now includes description (the run Prompt)
and issue_title_template; title and project_id stay cosmetic/routing.
UpdateAutopilotTrigger no longer transfers on every PATCH — it compares the
persisted before/after and transfers only on a real cron/timezone/enabled/
event_filters change, not a label-only or no-op PATCH. Adds real handler tests
(prompt->all, title->none, cron->one+isolation, label->none, no-op->none).

Must-fix 3: real merge-path regression (TestMergeCommentIntoPendingTask_
FailClosedKeepsOriginalSnapshot) drives mergeCommentIntoPendingTask and asserts
a fail-closed workspace preserves the queued task's full snapshot; fail-open
control completes the owner_fallback merge.

Docs: migration 172 comment reworded to legacy-writer/unbackfilled-lineage
semantics (source NULL is not strictly pre-migration); PR description synced.

Migration renumber vs latest main (must-fix 2) deferred to pre-launch per Bohan.

* feat(admission): unify dispatch outcome + close rerun/chat/autopilot invoke holes (MUL-4525)

P0 first increment toward a platform-wide execution-admission contract so a
user who names an execution target always gets a definite result and never a
silent no-op, and so blocked targets are reported without leaking private-agent
details.

Backend:
- New shared contract (handler/admission.go): DispatchOutcome / DispatchStatus
  (queued/coalesced/deferred/blocked) + stable, enumeration-safe
  DispatchReasonCode set, plus writeDispatchBlocked() whose legacy `error`
  string never reveals target existence.
- Rerun (task.go / task_lifecycle.go): re-validate the operator can invoke the
  RESOLVED target agent (historical agent for a task_id rerun) before any
  cancel/enqueue; blocked returns a structured 403 and mutates nothing
  (ErrRerunInvokeNotAllowed).
- Chat send (chat.go): re-run canInvokeAgent on every send, not just the softer
  canAccessPrivateAgent view gate; a revoked permission blocks before the
  message/attachments/task persist.
- Autopilot manual "run now" (service/autopilot.go): admission now keys on the
  current CLICKER, not the autopilot creator — clicker admission and clicker
  attribution no longer fork. Automation (schedule/webhook) still falls back to
  the creator gate. Added reason_code to the run response for the UI.

Frontend:
- triggerAutopilot response is schema-parsed; handleRunNow branches on run
  status and shows a localized, reason_code-based warning for skipped/failed
  instead of a false-success toast.
- Chat send and rerun surface the structured 403 reason_code as localized
  toasts (dispatchReasonCode helper) instead of a generic failure.
- Additive fields only; older clients keep working. i18n added to all 4 locales.

Tests: rerun fail-before-mutation gate, autopilot clicker-vs-creator fork
(service + handler), reason-code classification, and a malformed-response
schema test. Backend handler+service suites and FE typecheck/lint green.

* test(cmd/server): thread nil invoke gate through RerunIssue call sites (MUL-4525)

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

* fix(admission): typed reason codes + run-now whitelist + real security tests (MUL-4525)

Addresses Elon's review of the P0 first increment (must-fix 1–3).

1. Run now no longer has a false-success branch. handleRunNow now classifies on
   a whitelist via a pure runNowToastKind(): only issue_created/running →
   success; skipped → warning; failed and any unknown/future status → error. Add
   run-now-toast unit test over all five status classes plus reason-code → key
   mapping.

2. reason_code is a typed value decided at the admission source, not
   reverse-engineered from English failure text. New leaf package
   internal/dispatch holds the canonical ReasonCode enum (shared by handler +
   service so they can never drift). shouldSkipDispatch / errDispatchSkipped /
   the fail path now carry a typed code through DispatchAutopilotManual straight
   into the response; the substring classifier is deleted. Fixes the two missed
   branches: attribution fail-closed → attribution_blocked (typed errors.Is),
   "agent has no runtime bound" → runtime_offline. Regression tests for both.

3. Security acceptance tests exercise the REAL handlers, not injected callbacks:
   - Chat: create session while invokable → revoke invoke (flip to private, keep
     owner-view) → send returns 403 + reason_code with zero chat_message / task
     writes.
   - Rerun: private historical agent through RerunIssue + canInvokeAgent — a
     non-invoking workspace owner is refused 403 + reason_code and mutates
     nothing (fail-before-mutation); the agent owner is allowed 202.

No migration; reason_code is a decision-time value only the manual "run now"
response carries. Additive on the wire. Backend build/vet/handler+service
suites and FE typecheck/lint/vitest green. (Migration-prefix collision with main
remains the deferred pre-merge renumber.)

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

* test(admission): make must-fix 3 acceptance tests prove the invariant (MUL-4525)

Addresses Elon's round-3 narrow review — the two security tests were not yet
falsifiable against the bugs they must catch.

- Rerun: after enqueuing the historical task, reassign the issue to a SECOND
  agent that the denied user CAN invoke. Now the current assignee and the
  task_id agent differ, so a rerun that wrongly validated the current assignee
  would let the denied user through — the 403 proves the gate is keyed on the
  historical private agent. The allow case now asserts the reran task's agent_id
  is the historical agent, not the current assignee.

- Chat: the blocked send now carries a valid, still-unbound attachment. After
  the 403 the test asserts the attachment's chat_session_id and chat_message_id
  are both still NULL, guarding against anyone moving attachment binding ahead
  of the invoke gate.

Test-only. Full internal/handler Go suite green.

* feat(comments): surface blocked @mention trigger_outcomes instead of silent no-op (MUL-4525 §2)

A comment that @mentions an agent/squad the author cannot invoke used to save
with zero feedback — the user assumed a bug. Now the explicit-mention path
reports a per-target outcome on both preview and create/edit.

Backend (server/internal/handler/comment.go):
- resolveMentionedAgentCommentTriggers collects blocked outcomes instead of a
  silent `continue`. The invoke gate is evaluated BEFORE any archived/runtime
  state is read, so a caller who cannot invoke a private target only ever sees
  the generic invocation_not_allowed and can never enumerate its existence.
- enqueueCommentAgentTriggers returns queued/coalesced/deferred/blocked per
  explicit mention; enqueue errors are typed (attribution_blocked via
  errors.Is), not swallowed. Implicit routing (assignee/thread/conversation)
  carries no outcome — the user never named those targets.
- trigger-preview returns `blocked[]`; create/edit return additive
  `trigger_outcomes[]`. One blocked mention never fails the comment.

Frontend:
- Composer shows a warning chip for blocked mentions before sending; after
  sending, a "posted, but N not triggered" toast (blocked-only; coalesced/
  deferred are success-shaped). Additive schema + defensive parse; i18n ×4.

Tests: handler partial-success + enumeration-safety acceptance tests; core
outcome-parse + preview-schema tests; hook/parity updated. Backend
handler+service suites and FE typecheck/lint/vitest green.

* i18n(admission): clearer, consistent blocked-trigger copy (MUL-4525)

Reword the awkward "you are not allowed to run this autopilot's assignee" and
polish all MUL-4525 blocked/partial copy across en/zh-Hans/ja/ko:

- Unify on "you don't have permission to use this <agent|target>" (zh: 没有…的
  使用权限) for autopilot Run now, comment mentions, rerun, and chat send —
  replacing the various "not allowed to run/trigger" phrasings.
- Align zh to the glossary term 智能体 (was mixed "Agent"), matching the
  surrounding UI voice (e.g. agent_link_no_access).
- Drop jargon: "blocked by an admission policy"/"被准入策略拦截" → "the run was
  blocked"/"本次运行已被拦截"; "attributed"/"归因" → plainer wording.
- Comment copy counts "mentions" (was "targets") for consistency with the chip.

Backend dispatchBlockedFallbackMessage (old-client English fallback) reworded to
match; its enumeration-safety test assertion updated. Copy-only — no key/logic
changes; parity + typecheck green.

* fix(comments): one outcome per explicit mention + FE success whitelist (MUL-4525)

Addresses Elon's round-2 review of the §2 comment trigger_outcomes.

1. Separate execution dedup from per-target outcomes. resolveMentionedAgent-
   CommentTriggers now returns triggers (deduped by executing agent) AND one
   commentMentionTarget per EXPLICIT mention. enqueueCommentAgentTriggers returns
   a per-executing-agent result map; commentTriggerOutcomes fans each agent's
   status to every target that resolved to it. So @Agent A + @Squad S(leader=A)
   coalesces to ONE task but yields TWO outcomes. The squad-leader self-suppress
   branch now returns a definite `deferred` outcome instead of no result. New
   CreateComment test asserts 1 task, 2 outcomes.

2. Frontend no longer treats an unknown status as success. unhandledComment-
   TriggerOutcomes whitelists queued/coalesced/deferred as handled; blocked and
   any unknown/future/empty status warn (mirrors the Run now whitelist). The
   preview schema's `blocked` now drops malformed entries INDIVIDUALLY instead of
   z.array(...).catch([]) discarding the whole set. Regression tests for the
   unknown status and the per-item drop.

Backend handler suite + go vet, FE typecheck/lint/vitest green.

* fix(comments): honest role + status in trigger_outcomes fan-out (MUL-4525)

Addresses Elon's round-3 review of the §2 fan-out.

1. Execution merge preserves the squad-leader role instead of first-mention-
   wins. The dedup now UPGRADES an already-added plain @agent trigger to a
   @squad-leader trigger for the same agent, so @Agent A + @Squad S(leader=A)
   always runs as a leader task (is_leader_task + squad_id=S) regardless of
   mention order — the daemon still injects S's briefing. When two DIFFERENT
   squads share one leader, the single run carries one squad's context and the
   other squad is reported `coalesced` (folded), never a second `queued`. The
   enqueue result now records the executed squad so the fan-out can tell them
   apart. Tests assert the task role in both orders and the two-squad split.

2. Squad-leader self-suppression no longer fakes success. The self-trigger
   guard keys on the latest task ROLE with no status filter, so a long-completed
   task also suppresses; reporting `deferred/already_active` when nothing is
   active was a false success. The branch now reports `deferred` only when a
   real non-terminal task is active (its reconcile covers the comment), else a
   non-success `blocked` + new `already_handled` reason. Fixed the reversed
   helper-semantics comment. New handler test covers the completed-task branch.

Backend handler+service suites and go vet green.

* fix(comments): fail-closed active-task check, never fake deferred (MUL-4525)

Elon round-4 must-fix: hasActiveTaskForIssueAndAgent swallowed DB errors by
returning true, so both call sites could turn a query failure into a
success-shaped `deferred/already_active` — a silent false success, exactly what
this issue forbids for admission-query failures.

- hasActiveTaskForIssueAndAgent now returns (bool, error).
- Two pure decision helpers govern the branches, fail closed on error:
  - decidePostMergeMiss: on query error, do NOT enqueue a fresh task (duplicate
    concurrent-run risk) AND report non-success blocked/internal_error; a
    confirmed active task defers; a confirmed-none enqueues fresh.
  - decideSuppressedLeaderOutcome: on query error, blocked/internal_error; a
    confirmed active run defers; else self_trigger_suppressed. Never a fabricated
    deferred.
- Renamed reason already_handled -> self_trigger_suppressed (Elon non-blocking
  note): the old name implied the new comment was already processed, but the
  real meaning is a suppressed self-trigger.

Deterministic unit tests cover the query-failure branch at both call sites
(no fresh enqueue, non-success outcome) — a real DB fault can't be forced
through valid handler inputs, and the decision is what governs the behavior.
Backend handler+service suites and go vet green.

* fix(comments): honest merge outcome — refused merge is blocked, not fake coalesced (MUL-4525)

A pending-task merge previously reported success (coalesced) even when it
was refused or failed: attribution fail-closed and unknown DB errors both
returned handled=true, so the caller recorded coalesced for a merge that
never happened. mergeCommentIntoPendingTask now returns a distinguishable
commentMergeResult; commentMergeTerminalOutcome maps a real merge to
coalesced, a fail-closed refusal to blocked/attribution_blocked, and any
other failure to blocked/internal_error. Only "no queued task to fold"
falls through to the active-task decision. Adds pure coverage of the
mapping plus a fail-closed regression asserting the non-success outcome
and unchanged task count.

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

* fix(comments): name blocked @mentions in preview + toast instead of a vague count (MUL-4525)

The blocked-trigger preview showed a red "1 mention won't trigger" with no
name, and the post-send toast said "but 1 mention wasn't triggered" — the
user can't tell which target or why. Now each blocked mention renders its own
chip named from the mention markup the user typed ("Go · No permission"),
with an error indicator and a short reason; the toast names the single target
too. The wire outcome still omits the target name (enumeration-safety) — the
label comes from the user's own draft, so nothing new is disclosed.

Shares a blocked-trigger-copy module (long + short reason labels) between the
chip and the toast, and a pure mentionLabelsByTarget/parseMentions helper in
core (fresh regex per call — a shared global leaked lastIndex). Adds core +
chip tests; drops the now-unused trigger_blocked_count keys across locales.

- Execution-record (transcript) dialog header: the full on-behalf-of
  badge next to the status pill.

Adds a compact variant="avatar" mode to AttributionBadge, reusing its
source-label mapping and degraded-attribution tone. Renders nothing when
a run has no resolved accountable member.

9eddcaff10 fix(chat): defer cancellation-time finalization until the task transcript is stable (#5246)
A quick Stop before the agent's first token no longer races a late reply. Started-but-empty cancellations defer the empty/non-empty judgment until the daemon acks its transcript flush (or a grace-period sweeper fires), then settle to a single outcome. Empty outcomes persist a durable, creator-authorized draft restore (fetched/consumed via a dedicated endpoint, reconnect-safe and at-most-once) instead of broadcasting the prompt over the workspace bus.

Closes #5219

47f9c5813f fix(chat): reland archived-session unread + mount-race auto-read (MUL-4360) (#5333)
* fix(chat): correct unread — archived sessions + mount-race auto-read (MUL-4360)

Reland of #5315, which was reverted by #5332 as collateral in an unrelated
release-wide revert (to unwind 162/163 migration BLOCK from other PRs), not for
any defect in this code — Howard/Preflight assessed these changes WARN /
non-blocking. Restores all three fixes verbatim off current main:

- backend: ListAllChatSessionsByCreator derives unread_count=0 / has_unread=false
  for status='archived' rows via a CASE gate. last_read_at is untouched, so
  unarchiving restores the true unread state. Single source of truth for every
  unread surface (quick-chat FAB, sidebar Chat tab, chat-window header, mobile);
  installed desktop clients benefit with no app update.
- frontend: the archive mutation onMutate optimistically zeroes the row's unread
  so no badge counts a just-archived session in the frame before the refetch
  lands. Unarchive does not fabricate a count — the true state returns from the
  server refetch.
- frontend: auto-mark-read is deferred a tick and cancelled on cleanup, so a
  session that is only momentarily active on mount (persisted activeSessionId
  restored for one frame, then cleared by the URL->store effect) is not marked
  read; only a session that stays active past the tick is.

Verification: sqlc regenerate produces no drift; go test ./internal/handler
-run 'TestListChatSessions_ArchivedSessionReportsZeroUnread|TestSetChatSessionArchived_ClearsChannelBinding'
passes against a real Postgres; vitest mutations.test.tsx (3) and
use-chat-controller.test.tsx (8) pass; core + views typecheck clean.

* fix(chat): converge archived unread on chat:session_updated realtime event (MUL-4360)

Howard's #5333 review found a real cross-tab gap: the chat:session_updated
handler patched status but never unread, and chatSessionsOptions is
staleTime: Infinity, so a session archived in one tab kept its unread badge lit
in another tab/device forever — the same stuck-badge bug, one surface over.

Extract the inline handler into applyChatSessionUpdatedToCache and force
unread_count=0 / has_unread=false when payload.status === "archived", mirroring
the archive mutation's optimistic patch and the backend deriving unread=0 for
archived rows. Unarchive does NOT fabricate a count — the true unread returns
from the server refetch (last_read_at untouched). No sessions-list
invalidation; minimal field patch as reviewed.

Adds use-realtime-sync.test.ts coverage: an archived event zeroes a cached
unread row; an active event does not resurrect unread; a rename-only event
leaves unread untouched.

ace0f16cad fix(chat): badge unread chat replies that arrive while backgrounded (MUL-4485) (#5356)
Gate the Chat unread badge and chat auto mark-read on a shared useAppForeground() signal (document visible AND window focused). A reply arriving while the app is backgrounded now stays unread and badges, and clears when the user returns. Adds foreground-gating regression tests for the sidebar count and useChatController.

* feat(skills): search runtime local skills

* feat(skills): highlight matched substrings in runtime local skill search

Reuse the shared HighlightText (the same component the global search
command uses) to highlight matched substrings in a result's name,
provider, description, and path, so styling stays consistent across the
app. Narrow the search to the fields the row actually renders and drop
`key`, so every match maps to something visible. While a query is active,
lift the description's 2-line clamp so a match past the first two lines
stays on screen instead of being clipped.

* fix(chat): zero unread for archived chat sessions across all badges (MUL-4360)

Archiving a chat session flips status but deliberately does not advance
last_read_at, and ListAllChatSessionsByCreator counted unread
unconditionally. So an archived session that had unread replies kept
reporting has_unread=true / unread_count>0 — a stuck badge the user can
never clear (archived sessions are read-only and hidden from history, so
there is no mark-as-read entry). MUL-4372 fixed only the quick-chat FAB
surface; the sidebar Chat tab badge and the chat-window "other unread"
header still counted it.

Fix at the source: derive unread_count = 0 for status='archived' rows in
ListAllChatSessionsByCreator. Because has_unread is server-derived as
unread_count > 0, and all surfaces (FAB, sidebar via
countUnreadChatMessages, chat-window header, and mobile) read this one
payload, every badge drops archived sessions with no per-surface filter.
last_read_at is left untouched so unarchiving restores the true unread
state. Installed desktop clients benefit without an app update.

Also zero unread optimistically in the archive mutation so no badge
counts a just-archived session in the frame before the refetch lands
(FAB already filtered archived; this keeps sidebar/header consistent).

* fix(chat): stop auto-mark-read from clearing a transiently-active session on mount (MUL-4360)

The chat page persists `activeSessionId`, so on a bare `/chat` navigation it
restores the last-open session as active for one frame before its URL→store
effect (which runs AFTER useChatController's effects, since the hook is called
first) clears it back to null. The auto-mark-read effect fired in that gap and
marked the restored-but-never-opened session read — its unread badge vanished
though the right pane still showed "select a chat" and the user never opened it.
This is why the sidebar count dropped (e.g. 2 → 1) just by entering the tab.

Defer the read by a tick and cancel it on cleanup: a session that is only
momentarily active (restored on mount, then cleared) has its pending read
cancelled when activeSessionId changes; only a session that stays active past
the tick — a real select, deep link, or refresh — is marked read. A live-store
re-check in the timer is a belt-and-suspenders guard.

Adds the previously-missing auto-mark-read coverage: a stable-active session is
read after the tick; a momentarily-active one is not.

3bd69bdaa2 MUL-4432: add DM button on agent detail page (#5289)
* feat(agents): add DM button on agent detail page

The header gains a DM action next to Assign work. It shares the MUL-3963
invocation gate with assignment: allowed users land on the Chat tab with a
fresh compose bound to the agent via a new one-shot ?agent=<id> deep link
(consumed once the permission-filtered agent list resolves, then stripped);
denied users get an explanatory toast instead of a hidden affordance.

Closes MUL-4432

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

* fix(chat): harden the ?agent= deep link against races and undetermined permissions

Review follow-up for the DM button (PR #5289):

- An explicit user action (thread select, archive, manual new chat) now
  supersedes a still-pending ?agent= intent, so an intent deferred by slow
  agent/member queries can no longer fire late and clobber that choice.
- The composingNew reset reads the live store value; under StrictMode's
  effect replay the render-captured snapshot re-closed the compose pane the
  intent had just opened (one-shot guard rightly refuses to re-fire).
- A settled miss (revoked access, archived agent, bad id) now toasts and
  strips the param instead of silently keeping a re-fireable intent; still-
  loading queries keep the intent pending. Query errors never settle.
- useAgentPermissions exposes isLoading: the detail page disables DM while
  membership resolves instead of toasting a false not_member deny at a
  legitimate member.

The chat store test mock is now reactive (useSyncExternalStore) — with a
plain mutable ref React bails out of committing post-effect re-renders and
the StrictMode regression cannot reproduce. Both new regression tests fail
against the pre-fix code.

4763772c4f feat(chat): auto-focus compose box on new chat (#5146)
Starting a new chat (⊕ new chat on the Chat tab, or ⊕ / switching agent
in the floating window) now pulls keyboard focus into the compose box so
the user can type immediately, instead of having to click into it first.

Focus is driven by a monotonic `focusRequest` nonce bumped only by the
new-chat handlers, so selecting an existing chat or opening one via a
`?session=` deep link never steals focus. ContentEditor.focus() latches
through to onCreate when the editor is not yet mounted (immediatelyRender:
false), so the freshly-mounted compose box focuses on its first frame.

4a93f4ce41 fix(chat): advance selection to next chat when archiving the open session (#5110)
* fix(chat): advance selection to next chat when archiving the open session

Archiving the chat currently open in the two-pane Chat tab left the
conversation pane showing a now read-only, dangling session. Mirror the
Inbox list's handleArchive: move selection to the next chat in the
sorted, non-archived history list, fall back to the previous one, and
clear only when nothing is left. Archiving a non-open row is unchanged.

Closes MUL-4278

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

* fix(chat): route archive-advance through the shared controller

Address review of #5110:

- Advance now routes through handleSelectSession so selectedAgentId stays
  in sync when the next chat belongs to a different agent (a follow-up
  "new chat" no longer defaults to the archived chat's agent).
- Move the advance/next-prev/clear logic into use-chat-controller
  (advanceSelectionAfterArchive + archiveSession) and drive both Chat-tab
  entry points from a single ChatPage.handleArchive: the thread-list row
  AND the conversation header ⋯ menu (the header previously only flipped
  status, stranding the user on the archived read-only conversation).
- Mobile: archiving the open fullscreen conversation returns to the list.
- Floating window: archiving the open chat now advances to the next chat
  (with cross-agent sync) instead of clearing, matching the Chat tab.

Tests: controller test covers advance/fallback/clear/no-op + cross-agent
sync; thread-list test now asserts it delegates to onArchive.

* feat(chat): Chat V2 — first-class IM-style Chat tab (MUL-4171)

Replace the floating chat FAB/window with a first-class Chat tab under
Inbox, laid out as an IM-style two-pane surface (thread list + conversation).

Highlights:
- New Chat page (packages/views/chat/chat-page.tsx) with URL-addressable
  session selection; web + desktop routing wired up. Removes the old
  chat-fab / chat-window / resize-handles / context-items paths.
- IM thread list: agent avatar + last-message preview + IM timestamp, red
  unread *count* badge (read-cursor model), presence-gated typing vs waiting.
  Rename lives only in the conversation header ⋯ menu (not the list hover).
- Per-session conversation header (rename / view agent / delete), agent-aware
  empty state (avatar + name + description + starter prompts), and a
  deterministic clean-title derivation from the first message.
- Server: read-cursor unread model (migration 145) and per-user pinned agents
  (migration 146, dedicated chat_pinned_agent table + handler/queries).
  New-agent welcome chat auto-enqueues a real agent run (LLM intro, no
  static template).
- Design: fade the global --border token; borderless list headers on
  Chat/Inbox, kept (faded) on the conversation header.

Verified: pnpm typecheck (all packages), go build ./..., go vet, gofmt.

* feat(chat): make new-agent welcome read as an agent-initiated intro (MUL-4230)

The "meet your new agent" chat used to insert a fake user message
("👋 Hi! Please introduce yourself …") and have the agent reply to it, so
the thread looked like the creator prompting the agent.

Drop the persisted user message. Flag the auto-created session
is_agent_intro (migration 147) and drive the intro run server-side: the
daemon builds a proactive self-introduction prompt for such sessions
(buildChatPrompt) instead of a "reply to their message" prompt. The intro
stays LLM-generated; the thread now opens with the agent's own message, as
if it reached out first.

- migration 147: chat_session.is_agent_intro
- CreateChatSession carries the flag; sendAgentWelcomeChat no longer
  persists/publishes a user message
- daemon: ChatIntro threaded from session flag → intro prompt

* feat(chat): Settings toggle for the floating chat window (MUL-4235) (#5080)

* feat(chat): Settings toggle for the floating chat window (MUL-4235)

Re-introduce the floating chat overlay on top of Chat V2 as an optional,
Settings-gated surface instead of deleting it outright.

- Settings → Preferences → Chat: a switch (floatingChatEnabled, persisted
  client preference, default ON) to show/hide the floating window.
- FloatingChat wrapper owns the two gates: the preference, and the /chat
  route (hidden on the tab so the same activeSessionId isn't shown twice).
- ChatFab + a compact ChatWindow that reuse the shared useChatController and
  conversation components, so activeSessionId stays in lockstep with the tab.
- Restore use-chat-context-items so the overlay's @ surfaces the current
  issue/project (the 'current context' affordance) — the tab stays manual.
- i18n (en/zh-Hans/ja/ko), store unit tests.

typecheck: core/views/web/desktop green. tests: chat store 9, settings 82,
chat 39 pass.

* feat(chat): dedicated Chat settings tab, floating window opt-in (MUL-4235)

Address review: give Chat its own Settings tab instead of a section inside
Preferences, and default the floating window OFF (opt-in).

- New Settings → Chat tab (chat-tab.tsx) under My Account; moves the
  floating-window toggle out of the Preferences tab.
- floatingChatEnabled now defaults OFF — only an explicit enable from the
  Chat tab mounts the FAB/overlay.
- i18n: page.tabs.chat + a top-level chat block (en/zh-Hans/ja/ko);
  revert the Preferences chat section and its test mock; store tests updated
  for the opt-in default.

* refactor(chat): drop starter prompts from chat empty state (MUL-4237) (#5081)

The three starter prompts (List my open tasks by priority / Summarize what
I did today / Plan what to work on next) read as filler more than help, so
remove them along with the now-unused returning_subtitle ("Try asking").

The empty state keeps its agent-aware header — avatar + "Chat with {name}"
+ optional description — and the composer stays the entry point. Locale
keys dropped across en/zh-Hans/ja/ko (parity preserved).

Based on the Chat V2 branch (parent MUL-4171, #5076), not main.

* feat(chat): pin a chat to the top of the Chat list (MUL-4240) (#5082)

Builds on Chat V2 (#5076). Adds a per-conversation pin so a user can
keep important chats at the top of the IM-style thread list, above the
activity-sorted rest.

Backend:
- migration 148: chat_session.pinned_at (nullable) + partial index; the
  timestamp doubles as the pinned-group sort key and the boolean flag.
- list queries order pinned-first, then by most-recent activity.
- SetChatSessionPinned query + PATCH /api/chat/sessions/{id}/pin handler;
  pinning never bumps updated_at, so an unpinned chat won't jump the list.
- ChatSessionResponse.pinned + chat:session_updated carries the new state.

Frontend:
- ChatSession.pinned; setChatSessionPinned API + useSetChatSessionPinned
  with optimistic re-sort; shared sortChatSessions comparator.
- thread list: pin indicator on pinned rows + pin/unpin hover action;
  list sorted pinned-first so it stays ordered after cache patches.
- realtime patch re-sorts on pin change; en/ja/ko/zh-Hans strings.

Tests: SetChatSessionPinned handler test, sortChatSessions unit tests.

* fix(chat): stop welcome intro session repeating the same introduction (MUL-4259)

The is_agent_intro flag on chat_session is persistent, so every follow-up turn on a welcome session re-selected the self-introduction prompt in buildChatPrompt and the agent kept replying with the same intro instead of answering the user.

Gate resp.ChatIntro at claim time on the session still having zero human (role='user') messages via a new ChatSessionHasUserMessage query: the first, message-less server-driven turn introduces the agent; once the creator replies, later turns fall back to the normal reply prompt.

* fix(chat): address review findings + unbreak CI (MUL-4171)

- task:failed now refreshes the sessions list (invalidateSessionLists), so
  the thread-list preview / unread / sort stays correct after an agent
  failure — FailTask persists a failure chat_message but only broadcasts
  task:failed, mirroring the chat:done success path.
- Self-heal stale chat deep links: once the sessions list has loaded and a
  ?session= id isn't in it (deleted / no access / never existed) with nothing
  in flight, clear the selection instead of rendering an editable empty chat
  that would POST into a nonexistent session. Freshly-created sessions are
  exempt (they carry optimistic messages + a pending task).
- CI: add the new parameterless `chat` route to link-handler's
  WORKSPACE_ROUTE_SEGMENTS and to paths/consistency.test.ts (route set +
  expectedSegments) — keeps the two in sync, fixes the failing @multica/core
  test.
- Fix a MUL-4235/MUL-4237 merge collision that broke @multica/views
  typecheck: chat-window.tsx still passed the removed `onPickPrompt` prop to
  EmptyState.

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

* fix(chat): self-heal dangling session in shared controller, not just ChatPage (MUL-4171)

Re-review follow-up: the stale-session self-heal only lived in ChatPage, so
the floating ChatWindow still entered from a persisted activeSessionId and
would render an editable empty chat (then POST into a nonexistent session)
when the selected session was deleted / lost access off the /chat route.

- Move the self-heal into the shared useChatController so every surface (tab
  and floating window) drops a dangling activeSessionId once the sessions list
  has loaded and doesn't contain it.
- Harden ensureSession: trust the current id only when it's in the loaded list
  or is a just-created session still awaiting the refetch; a dangling id falls
  through to create a fresh session instead of POSTing into a 404.
- Exempt just-created sessions via an OPTIMISTIC-write signal
  (hasOptimisticInFlight: pending task or optimistic- message), not hasMessages
  — a session deleted elsewhere with real cached history stays eligible for
  self-heal. Add a unit test for the discriminator.

* test(views): fix app-sidebar useWorkspacePaths mock for the new chat nav (MUL-4171)

The AppSidebar personal nav gained a `chat` item, so it calls
`useWorkspacePaths().chat()` at render. The app-sidebar.test.tsx mock hadn't
been updated, so `p.chat` was undefined and every render threw
`TypeError: p[item.key] is not a function`, failing @multica/views#test in CI.

- Add `chat: () => "/acme/chat"` to the mocked useWorkspacePaths.
- Route the chat-sessions query key through a mutable `chatSessions` fixture.
- Add coverage for the Chat nav: renders the link, badges the summed
  unread_count, and hides the badge when all sessions are read — so this drift
  is caught next time.

* fix(chat): use the original floating window, not the rewritten one (MUL-4235) (#5102)

Follow-up to the merged #5080, which shipped a hand-written, simplified
ChatWindow and lost the original's animations / drag-resize / expand-minimize.
The floating window is just a quick entry point — it should be the original
UI, not a rewrite.

- Restore chat-window.tsx, chat-fab.tsx, chat-resize-handles.tsx and
  use-chat-resize.ts verbatim from main (0-diff): motion animations, drag
  resize, expand/minimize and the session dropdown are back.
- Restore the empty_state.returning_subtitle + starter_prompts i18n keys the
  original window renders (V2 had dropped them); drop the now-unused
  window.open_full_tooltip key the rewrite added.
- Settings gating is unchanged: FloatingChat still wraps the original FAB +
  window, gated by floatingChatEnabled (default off) and hidden on /chat.

* feat(chat): archive chats from the list, delete only from Archived (MUL-4263) (#5098)

Restore an archive flow as the reversible sibling of delete:
- Chat list hover now offers Archive (not Delete); pin/stop unchanged.
- A footer entry ('Archived · N') opens an Archived view listing archived
  chats; hard delete lives only there (hover -> unarchive + delete, with
  the existing inline confirm).
- Conversation header ⋯ menu mirrors this: active chats archive, archived
  chats unarchive/delete.

Backend: PATCH /api/chat/sessions/{id}/archive flips status active<->archived
(SetChatSessionArchived), broadcasts status on chat:session_updated so other
tabs re-sort into the right list. SendChatMessage already refuses archived
sessions, so archived chats stay read-only until unarchived.

* fix(chat): address floating-window + archived-agent review blockers (MUL-4171)

Re-review follow-up on the restored floating ChatWindow + archive flow:

1. Floating stale-session self-heal. The restored ChatWindow doesn't use the
   shared controller, so its ensureSession trusted any non-empty
   activeSessionId and there was no dangling-session cleanup — a deleted /
   no-access persisted session could send into a nonexistent session. Ported
   the same guard used for the tab: a self-heal effect that clears a dangling
   activeSessionId once the sessions list has loaded, and ensureSession only
   trusts an id that's in the list or has an in-flight optimistic write
   (hasOptimisticInFlight, reused from use-chat-controller). handleSend seeds
   the optimistic message + pending task before setActiveSession, so a
   freshly-created session is never mis-cleared.

2. Floating dropdown bypassed archive-first safety. Its active rows offered a
   hard-delete, letting the floating window destroy active chats and skip the
   "archive first, delete only from Archived" model. Active rows now ARCHIVE
   (reversible, one-click) like ChatThreadList; the floating window offers no
   hard-delete — unarchive/delete live only in the full Chat page's Archived
   view (reachable via expand). Removed the now-dead delete-confirm machinery.

3. Orphan user message on archived-agent send. SendChatMessage created the
   chat_message before EnqueueChatTask, which rejects an archived / runtime-less
   agent — a stale client would land a user message then get a 500, orphaning
   it. Added a preflight that checks the session agent's archived / runtime
   state and returns 409 before any mutation, plus a handler test asserting the
   send is rejected with no message persisted.
