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.

* 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.

* 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
AvatarSize union (packages/ui/lib/avatar-size). Switch the on-behalf-of badge
avatar from size={14} to size="xs" (16px) after merging main.

* 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).

* chore(attribution): re-trigger CI (dropped synchronize event on 249090260)

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.

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

* 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.

* 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.

* 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.

* chore(attribution): renumber migrations to 167-173 after syncing main

Merged latest main (which took 166_project_dates) and shifted the attribution
migration series off the 166 collision: 166->167 agent_task_attribution,
167->168 accountable_user, 168->169 rule_version, 169->170 rule_version_index,
170->171 fail_closed, 171->172 trigger_publisher, 172->173 invariant_check.
Updated the internal cross-references in the migration comments accordingly.
Fixes TestMigrationNumericPrefixesStayUniqueAfterLegacySet on the merge tree.

* 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.)

* 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.

* 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.

* feat(attribution): accountable-member avatar on agent task rows + transcript header (MUL-4302)

Surface who each agent run is on behalf of where runs are actually
browsed:
- Agent detail activity tab: an avatar-only AttributionBadge on every
  task row's meta line (Now + Recent work), tooltip carries the name +
  resolution source.
- 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.

* feat(composio): server-side connect flow + connections REST (Notion MVP) (MUL-3720)

Compose the merged server/pkg/composio SDK into a user-facing connection
manager: signed-state connect handshake, local user_composio_connection
mirror, idempotent disconnect, and a per-user MCP session helper (not yet
wired into task dispatch).

- migration 127_user_composio_connection (no FK/cascade, per DB rules)
- sqlc queries: upsert (idempotent on user_id+connected_account_id), list
  active, owner-scoped get, mark revoked
- internal/integrations/composio: signed HMAC-SHA256 state, BeginConnect,
  CompleteCallback (idempotent upsert), ListConnections, Disconnect
  (upstream 404 = idempotent success), CreateMCPSession (no-op when empty,
  pins connected_accounts per toolkit), CallbackRedirect
- REST handlers under /api/integrations/composio (user-scoped, 503 when
  COMPOSIO_API_KEY unset): connect/init, callback (302), connections list,
  delete
- router wiring gated by COMPOSIO_API_KEY; COMPOSIO_AUTH_CONFIGS_JSON maps
  toolkit->auth_config (MVP: notion); state secret from COMPOSIO_STATE_SECRET
  or derived from JWT_SECRET; callback base from COMPOSIO_CALLBACK_BASE_URL
  or MULTICA_PUBLIC_URL
- tests: state (expire/tamper/wrong-secret), service (mapping, callback
  idempotency, non-success, disconnect owner/404 idempotency, MCP pin),
  handlers (httptest), redact regression for Bearer mcp_ tokens

MVP scope: Notion only; no task-dispatch overlay, sharing, or webhook
event handling (later stages).

* fix(composio): bind callback account to user + idempotent revoked disconnect (MUL-3720)

Address PR 4608 review (CHANGES_REQUESTED):

- callback: verify connected_account_id with Composio before mirroring it.
  The signed state only proved user/toolkit/exp, so a valid state paired with
  a tampered connected_account_id would be written verbatim. CompleteCallback
  now calls ListConnectedAccounts and fails closed (ErrAccountVerification)
  unless the account belongs to the state's user (composio_user_id == multica
  user id) and was created under the toolkit's auth config. No row is written
  on mismatch / unknown account / upstream error.

- disconnect: short-circuit to a no-op when the local row is already revoked,
  before touching upstream. Previously a second DELETE re-hit Composio and a
  non-404 upstream error surfaced as a 502, breaking the 204-idempotent
  contract.

- CreateMCPSession: document the v1 single-active-connection-per-(user,toolkit)
  constraint and make duplicate selection deterministic (newest-wins, rows are
  connected_at DESC) instead of order-dependent map overwrite. Stage 3 owns the
  real single-account-enforcement vs multi-account-shape decision.

Tests: tampered/wrong-auth-config/unknown-account callback rejection, revoked-row
disconnect no-op (asserts upstream not re-hit). composio pkg 85% coverage; all
green.

* feat(composio): list all toolkits + dynamic auth-config resolution (MUL-3720)

Yushen's follow-up to the Notion MVP: surface the full Composio toolkit
catalog, render it in Settings, and drop the static env mapping in favor of
dynamic auth-config discovery.

Config correctness (per Composio docs):
- Remove COMPOSIO_AUTH_CONFIGS_JSON entirely. The toolkit→auth_config mapping
  is now resolved at request time from the project's /auth_configs (cached,
  5-min TTL), so enabling a toolkit is a dashboard action, not a redeploy.
- Do NOT add COMPOSIO_PROJECT_ID. The project API key (x-api-key) authenticates
  to exactly one project; the project is resolved from the key. Only org-level
  endpoints use x-org-api-key, which this integration never calls.

Backend:
- SDK: server/pkg/composio/auth_configs.go — ListAuthConfigs (toolkit_slug,
  is_composio_managed, show_disabled, limit, cursor).
- service: dynamic resolver (authConfigMap cache; betterAuthConfig prefers a
  custom/white-label config over Composio-managed, newest wins); BeginConnect
  and CompleteCallback resolve via it; ListToolkits fetches the full catalog
  (paginated, capped) annotated with connectable = has an enabled auth config,
  connectable-first ordering.
- handler + route: GET /api/integrations/composio/toolkits (user-scoped, 503
  when COMPOSIO_API_KEY unset) returning slug/name/logo/category/connectable.

Frontend:
- core: ComposioToolkit/ComposioConnection types, api client methods, and
  composio query options (@multica/core/composio).
- views: Settings → Integrations now has a Composio section rendering every
  toolkit as a card with search. Connect is gated on `connectable`;
  non-connectable toolkits show a muted "not configured" hint instead of a
  dead button. Connected toolkits show a badge + Disconnect (with confirm).
- i18n: composio block added to en/zh-Hans/ja/ko settings.

Tests: SDK + service (dynamic resolution, custom-over-managed preference,
connectable flag, resolver-error soft-degrade) and handler toolkits endpoint;
composio pkg 85.7% coverage. go build/vet/gofmt clean; core+views typecheck,
core+views lint, and core tests (691) all green.

* fix(composio): close cross-toolkit callback fail-open by signing auth_config_id into state (MUL-3720)

Re-review blocker: CompleteCallback resolved the toolkit's auth config at
callback time and ignored a resolve error/empty result, while
verifyAccountOwnership skipped the auth-config comparison when the expected
value was empty. A user could then pass another toolkit's connected_account_id
into this toolkit's callback — the owner check passed and it was written under
the wrong toolkit_slug/account binding.

Fix: the auth_config_id is already resolved in BeginConnect (before the state
is signed), so sign it into the state and compare it exactly at callback. No
re-resolve, no fail-open. verifyAccountOwnership now fails closed when the
expected auth config is empty (rejects instead of skipping) and requires an
exact match — closing the cross-toolkit binding gap.

Tests: state round-trips auth_config_id; BeginConnect signs it; callback
rejects wrong/cross-toolkit auth config and an empty (no-mapping) auth config
fails closed. composio pkg 85.2% coverage, all green.

Frontend (non-blocking): the Composio settings tab now surfaces an error when
the connections query fails instead of silently rendering everything as
unconnected.

* fix(composio): hide Settings section entirely when integration unconfigured (MUL-3720)

Decision (option 2, hide-then-merge): don't show a card that leaks the internal
COMPOSIO_API_KEY env-var name to every end user. IntegrationsTab now gates the
whole Composio section (heading + body) on the toolkits query — a 503 means the
key is unset, so the section is withheld instead of rendering the not-configured
card. Admin-only setup guidance is a later, role-gated affordance.

Removed the notConfigured card (and now-unused ApiError import) from
ComposioTab; it only mounts when configured. views typecheck + lint clean.

* fix(composio): callback endpoint should not require Multica auth (MUL-3843) (#4709)

* fix(composio): move OAuth callback out of the Auth group (MUL-3843)

Composio 302-redirects the browser to /api/integrations/composio/callback
at the end of the OAuth flow, but PR #4608 mounted it inside the cookie-auth
middleware group. When the session cookie is absent (expired session,
SameSite=Strict / Safari ITP, private window, self-hosted callback subdomain)
the Auth middleware returned a hard 401 and a JSON blob instead of the
settings redirect, breaking the flow.

Identity never came from the cookie anyway: it is carried by the HMAC-signed
state param that CompleteCallback verifies (signature, expiry, replay) and
cross-checked by verifyAccountOwnership; h.Composio == nil still 503s. So the
callback is registered alongside the other public OAuth/webhook routes; the
other four composio endpoints stay session-gated.

* feat(composio): inject MCP overlay into agent runtime at task dispatch (MUL-3721) (#4704)

Stage 3 of the Composio epic. Wires the per-user Composio MCP session into
every agent task so the agent process sees the initiator's connected tools
without any prompt-time plumbing.

Server side
  - Migration 128 adds agent_task_queue.runtime_mcp_overlay JSONB plus a
    BEFORE-UPDATE trigger that wipes the column on any transition into a
    terminal status (completed / failed / cancelled). A trigger is the single
    source of truth — future queries that flip status cannot bypass it.
  - composio.Service.BuildTaskOverlay(userID) reuses CreateMCPSession and
    emits the Claude-style { mcpServers: { composio: { type: http, url,
    headers } } } shape the daemon's existing sidecar generators consume.
    Returns (nil, nil) on zero active connections so we never burn a
    Composio session for a user with nothing to call.
  - TaskService grows a Composio ComposioOverlayBuilder seam, wired in
    router.go after composiointeg.NewService succeeds. Five enqueue paths
    (issue / mention / quick-create / chat / auto-retry) attach the overlay
    after CreateAgentTask returns and before the daemon is notified — so
    every claim reads a settled row, with no second daemon hop. Best-effort:
    a builder failure logs and proceeds with no overlay.
  - resolveInitiatorFromTriggerComment derives the initiator user from the
    trigger comment when it was authored by a member. Agent-authored
    triggers are not treated as initiators (their connected-apps view is
    empty by construction).

Daemon side
  - handler/daemon.go claim path merges task.runtime_mcp_overlay onto
    agent.mcp_config via mergeMCPOverlay before populating
    TaskAgentData.McpConfig. Overlay wins on server-name collisions
    because it carries the live user-scoped session URL. Errors fall back
    to the agent config unchanged — a bad overlay must not surprise-disable
    saved MCP tools. The existing execenv sidecar generators (cursor /
    codex / openclaw / opencode / hermes-kiro) need no changes: they keep
    consuming the merged result through TaskAgentData.McpConfig.

Tests
  - 9 merge cases (mcp_overlay_test): both-nil short-circuit, agent-only
    pass-through, overlay-only canonicalization, two-side merge, name
    collision (overlay wins), top-level key preservation, malformed agent
    fallback, malformed overlay fallback, non-object server rejection.
  - 4 dispatch cases (composio): zero-connections returns nil without
    CreateSession, happy-path emits the right shape with the right user
    id, empty-URL defensive branch, SDK error surfacing.
  - 4 TaskService helper cases: nil Composio is a no-op (Queries-safe),
    invalid initiator does not call the builder, nil overlay skips the
    UPDATE, builder error swallowed without panic.
  - Migration 128 verified to roll up + down + up cleanly against the test
    database.

Out of scope (deferred): assignment-triggered enqueue paths with no
trigger comment get no overlay attached today (no initiator UUID flows
through enqueueIssueTask in that case). Retry paths recompute the overlay
fresh from the parent's initiator_user_id instead of inheriting the bearer
from the parent row, so a stale token can never resurface on a retry.

    * issue/mention comment by agent   -> inherit via comment.source_task_id

- BuildTaskOverlay (composio dispatch) now takes (ctx, originatorUserID,
  agent) and short-circuits on five gates: invalid originator,
  originator != agent.owner_id, empty allowlist, empty intersection of
  allowlist ∩ active connections, defensive empty session URL. Composio
  CreateSession is called with BOTH `toolkits.slugs` (the intersection)
  AND `connected_accounts` (the pinned account ids), narrowing the
  tool-router twice.
- The originator-vs-owner gate closes the agent-fanout privacy hole: any
  workspace member who can @-mention a public agent used to project the
  owner's connected apps into their run. Now the overlay only mounts
  when the human at the top of the chain IS the agent owner.

Tests:
- dispatch_test.go covers all 5 gates plus uppercase/whitespace slug
  normalisation.
- task_runtime_mcp_overlay_test.go covers the no-op gates of the new
  applyRuntimeMCPOverlay signature.
- agent_composio_allowlist_test.go (handler): owner roundtrip
  (list/empty/null), workspace-admin silent-drop, owner-only GET
  visibility, pure normaliseComposioToolkitAllowlist.
- resolve_originator_test.go (service, DB-backed): member-authored,
  agent-authored inherits via comment.source_task_id, invalid id.

* fix(composio): accept nested connected account auth config

* feat(views): creator-only MCP tab for per-agent Composio allowlist (MUL-3870) (#4743)

Stage 3.2 frontend on top of the Stage 3.1 backend (MUL-3869, 4708dba97).
Adds an agent-detail tab that lets the agent owner pick which of their own
active Composio connections this agent may mount as MCP servers, writing the
selection to agent.composio_toolkit_allowlist via the existing PUT /api/agents.

- core/types: composio_toolkit_allowlist (+ _redacted) on Agent; tri-state
  composio_toolkit_allowlist on UpdateAgentRequest (omit/no-change, null/clear,
  array/replace), matching the backend contract.
- core/agents: useUpdateAgentAllowlist - optimistic mutation hook (patches the
  cached workspace agent list, rolls back on error, invalidates on settle).
- views: AgentMcpTab renders the owner's active connections as checkboxes;
  empty state links to Settings -> Integrations; defensive redacted state.
- views: wired into AgentOverviewPane as tab "composio_mcp", labeled "MCP Apps"
  to disambiguate from the existing raw-JSON "MCP" (mcp_config) tab. The entry
  is gated to the creator (currentUserId === agent.owner_id), matching the
  backend's owner-only read/write of the allowlist.
- i18n: tabs.composio_mcp + tab_body.composio_mcp.* in en/ja/ko/zh-Hans.
- tests: agent-mcp-tab.test.tsx (gating, toggle->allowlist body, active-only,
  empty, redacted); e2e/agent-mcp.spec.ts (creator sees tab + PUT body,
  non-creator hidden) with Composio + agent endpoints mocked at the boundary.

Note: the product spec says "creator"; the schema has no creator_id - the
backend gate and redaction are keyed on owner_id, so the tab uses owner_id.

* feat(agents): agent invocation permission system (MUL-3963) (#4844)

* feat(agents): agent invocation permission system (permission_mode + invocation targets)

MUL-3963: split who may INVOKE an agent out of the overloaded visibility
column into an explicit, extensible model on feature/composio-integration.

- DB: agent.permission_mode (private|public_to) + agent_invocation_target
  table (workspace/member/team targets) + lossless backfill from visibility
  (migration 130).
- canInvokeAgent: owner-only for private (NO admin bypass, NO A2A bypass);
  public_to honours the allow-list; A2A judged by the top-of-chain originator.
- All trigger paths rewired: issue assign, comment @agent/@squad, chat,
  quick-create, autopilot, squad leader, child-done.
- Agent API: permission_mode + invocation_targets on responses and
  create/update (owner-only writes); legacy visibility kept as a derived field
  so old clients never see a permission widening.
- Composio: BuildTaskOverlay now FOLLOWS invocation permission and uses the
  agent OWNER connection (removed the originator==owner gate); front-end warns
  when a shared agent enables Composio apps.
- CLI: --permission-mode / --public-to-workspace / --public-to-member (legacy
  --visibility still mapped).
- Frontend: AccessPicker (Private / workspace / specific people / team soon),
  permission rules mirror canInvokeAgent, Composio warning banner.
- Tests: migration backfill, admin cannot invoke others private, public_to
  workspace/member whitelist, A2A by originator, Composio overlay uses owner
  connection.

* feat(agents): stackable, mixed public_to invocation targets (MUL-3963)

Follow-up on PR #4844: public_to now supports selecting MULTIPLE, MIXED
targets on one agent (e.g. Public to workspace + specific people + team),
with canInvokeAgent admitting on ANY matching target (OR).

- Frontend AccessPicker: reworked from a single exclusive kind into a
  stackable multi-select — an "Everyone in workspace" toggle, a member
  multi-select checklist, and a (disabled, v1) team placeholder can be
  combined freely. Emits the full union of selected targets; empty union
  collapses to Private. Existing team targets are preserved across saves.
  Added the access.public_group locale string (en/zh-Hans/ja/ko).
- Backend already supported this (agent_invocation_target is multi-row per
  agent; create/update take a target ARRAY and batch-replace the whole
  allow-list; canInvokeAgent OR-matches). Added tests to lock it in:
  mixed member+team targets, overlapping-member batch replace, and
  workspace+member stacking then narrowing.

* fix(agents): address review on invocation permission (MUL-3963)

张大彪 review on PR #4844 — three blockers + product ruling + nits:

1. Migration 130: drop the FK/cascade on agent_invocation_target
   (agent_id, created_by) per the Multica no-FK rule; relationships are now
   maintained in the app layer (matching MUL-3515 §4). Added
   DeleteAgentInvocationTargetsByArchivedRuntimeAgents and call it before
   DeleteArchivedAgentsByRuntime in all three runtime-delete paths
   (runtime.go x2, runtime_profile.go) so hard-deleting agents can't orphan
   target rows.
2. revokeAndRemoveMember: prune the leaving member's member-target grants
   (DeleteAgentInvocationTargetsByMember) in the same tx as the member-row
   delete, so a re-invited user can't reclaim a stale invocation grant.
3. Empty public_to is a phantom — parsePermissionInput now normalises a
   public_to with no resolvable targets to a single workspace target, so
   `--permission-mode public_to` alone (and any empty target array) means
   "public to workspace" instead of "shared but nobody can run it".

Product ruling: the system/no-human-originator → workspace-target path in
canInvokeAgent is a deliberate, documented exception (webhook/system/
workspace-wide automation); member/team targets still fail closed without a
resolved originator. Documented in code + locked with a test.

Nits: refreshed the stale "originator must be owner" comments — models.go
(via migration 130 COMMENT ON COLUMN + sqlc regen for composio_toolkit_allowlist
and originator_user_id) and agent-mcp-tab.tsx — to the owner-connection +
invocation-permission rules.

Tests: member remove/re-add regression, system workspace exception + member
fail-closed, empty public_to → workspace (plus the earlier mixed/overlap/
batch-replace suite). Migration 130 applied to the test DB; Go handler/service/
composio suites green; views typecheck clean.

* fix(agents): scope member invocation-target cleanup to one workspace (MUL-3963)

张大彪 3rd review — cross-workspace permission bug + comment nits:

- DeleteAgentInvocationTargetsByMember was a GLOBAL delete by user id, so
  removing a user from workspace A also wiped their member-target grants on
  agents in workspace B. Scoped it to a single workspace by joining through
  agent.workspace_id; revokeAndRemoveMember now passes (workspaceID, userID).
- Regression test TestRevokeMember_InvocationTargetCleanupIsWorkspaceScoped:
  same user allow-listed by agents in two workspaces; removal from one leaves
  the other workspace's target intact.
- Nits: refreshed the remaining stale "originator == agent.owner_id" /
  "owner-vs-originator" comments — CreateRetryTask (agent.sql, regenerated),
  and the AgentResponse allowlist doc + ListAgents/UpdateAgent redaction
  rationale in agent.go — to the owner-connection + invocation-permission rule.

Migration 130 applied to the test DB; Go handler/service/composio suites green;
go vet clean.

* fix(agents): agent access owner-only editable, read-only for others (MUL-3963) (#4853)

* fix(agents): make agent access owner-only editable, read-only for others (MUL-3963)

Interaction bug: a non-owner (incl. workspace admin) could open the AccessPicker
and set an agent public — the backend silently ignored it and the UI bounced
back to private. Access is owner-only, so non-owners must see a read-only state
and the backend must reject real changes explicitly.

Frontend:
- AccessPicker renders a static, non-interactive read-only state when the
  viewer is not the owner: the current access value + a lock affordance + a
  tooltip "Only the agent owner can change who can run this agent." No clickable
  trigger is rendered, so a non-owner can never open a control the backend would
  reject (the GitHub/Notion pattern for permission settings you can see but not
  edit). The editable multi-select picker is unchanged for the owner.
- agent-detail-inspector gates the picker on ownership specifically
  (currentUserId === agent.owner_id), NOT the general canEdit (which also admits
  admins, who may edit other fields but not access).
- New locale key access.owner_only_readonly (en/zh-Hans/ja/ko).

Backend:
- UpdateAgent now returns an explicit 403 when a non-owner submits a REAL
  permission change (permissionInputChangesAgent compares requested mode +
  target set against the persisted state); a no-op resubmit (admin PATCH-as-PUT
  echoing unchanged permission) is still tolerated so admin edits of other
  fields keep working. Replaces the previous silent-drop that caused the bounce.

Tests:
- access-picker.test.tsx: non-owner gets a non-interactive read-only display
  with the owner-only tooltip; owner gets an interactive picker; owner can pick
  a member and stack workspace + member.
- TestUpdateAgent_AccessChangeIsOwnerOnly: admin real change → 403; admin no-op
  resubmit → 200; admin editing other fields → 200; owner change → 200.

Incidental: fixed a pre-existing base typecheck break in
slash-command-suggestion.test.tsx (stray `signal` arg not in the suggestion
items type) that otherwise fails the whole @multica/views typecheck.

* fix(agents): compare legacy visibility, not expanded permission, for no-op detection (MUL-3963)

PR #4853 review: permissionInputChangesAgent expanded a legacy-only
visibility:"private" into a real private permission and compared it against the
agent's actual permission. A member-only public_to agent derives legacy
visibility "private", so an admin PATCH-as-PUT echoing visibility:"private"
while editing another field was misread as a public_to→private downgrade and
rejected with 403 — contradicting the "unchanged permission no-op is allowed"
contract.

Fix (per review): when a request carries ONLY legacy `visibility` (no
permission_mode / invocation_targets), derive the agent's CURRENT legacy
visibility from its real targets and compare the legacy string values. Equal =
no-op (allowed); a real legacy change (e.g. "workspace") still returns 403.
Requests that carry permission_mode / invocation_targets keep the precise
mode+target comparison.

Regression test TestUpdateAgent_LegacyVisibilityNoOpForMemberOnlyPublicTo:
member-only public_to agent — admin submitting visibility:"private" + a
non-permission field → 200 with targets unchanged; admin submitting
visibility:"workspace" → 403.

Go handler/composio suites green; migration 130 applied; go vet clean.

630feff1af MUL-3879: restore agent-authored squad-leader fallback in comment cascade (#4748)
After MUL-3794 rewrote the comment routing cascade, computeCommentAgentTriggers
returned early for every non-member author, so worker-agent result comments on a
squad-assigned issue no longer woke the assigned squad leader, breaking the
leader->worker->leader coordination loop.

Restore a narrow agent-authored fallback: when the issue is squad-assigned and
the author is not a member, route to routeAssignedSquadLeaderFallback. Member/
thread routing and explicit @agent/@squad mention routing are untouched, and the
lastTaskWasLeader self-trigger suppression is preserved (it lives inside
routeAssignedSquadLeaderFallback). Explicit mentions are handled before this
branch, so a mentioned target is never double-enqueued alongside the leader.

Single agent renders as avatar + presence dot + full sentence; several

(hover layers stay read-only tooltips); suppression reads as brightness,
not a ban glyph. Loading and preview errors render nothing.

Also: share one tooltip body across chip and popover rows, invalidate
cached previews after a comment lands (the enqueued task changes the
dedup answer), move the preview query key into issueKeys, and drop the
now-unconsumed status field from useCommentTriggerPreview.

to computeCommentAgentTriggers / computeAssignedSquadLeaderCommentTrigger
/ computeMentionedAgentCommentTriggers with current line numbers.

ce98b1c9ef fix(squad): skip leader on agent reply to explicit member @-mention (MUL-2624) (#3217)
When a user explicitly @-mentions an agent on an issue assigned to a squad,
the existing rule already suppresses the squad leader on the mention
comment itself — the user is routing deliberately, the mentioned agent
owns the next step. The leader was still woken on the agent's reply,
though, so it would re-@ the user every time the agent answered.

Extend the suppression to the second leg of that explicit exchange:
when an agent reply lands as a child of a member comment that carried a
routing @mention (agent/member/squad/all — issue cross-refs still
ignored), the leader stays out. The CreateComment handler already pins
agent parent_id == task.TriggerCommentID, so this fires exactly when
the agent's reply is provably tied to the upstream routing comment.
Top-level agent comments and agent-to-agent threads continue to wake
the leader so coordination keeps working everywhere else.

4d6b5ad06f fix(squad): wake leader when dual-role agent posts as worker (MUL-2218) (#2626)
* fix(squad): wake leader when dual-role agent posts as worker (MUL-2218)

The squad-leader self-trigger guard skipped a comment whenever the
author equalled the squad's leader id, regardless of the role the agent
was acting in. For an agent that holds both leader and worker roles in
the same squad, this meant the leader role never reacted to its own
worker output and the issue stalled.

Tag each enqueued task with is_leader_task and consult the agent's
most recent task on the issue from both self-trigger guards (comment
path + @squad mention path) — skip only when that task was itself a
leader task.

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

* fix(squad): inherit is_leader_task on retry task clone (MUL-2218)

CreateRetryTask cloned a parent task into a fresh queued attempt but
omitted is_leader_task from the column list, so the child silently fell
back to the column default (false). For a leader task that hit auto-retry
through MaybeRetryFailedTask, the retried task posed as a worker task —
the self-trigger guard then no longer recognised the leader's own
comments, re-opening the very loop MUL-2218 closes.

Inherit p.is_leader_task in the clone and add a query-level test that
covers both leader and worker retries.

e492d989d1 fix: trigger squad leader agent run on squad @mention in comment (#2592)
* fix: trigger squad leader agent run when squad is @mentioned in comment

Previously, enqueueMentionedAgentTasks only processed m.Type == "agent"
mentions, skipping squad mentions entirely. The shouldEnqueueSquadLeaderOnComment
path only fires when the issue is already assigned to a squad.

This adds handling for m.Type == "squad" in enqueueMentionedAgentTasks:
when a squad is @mentioned, look up the squad's leader agent and enqueue
a task for them (with the same dedup/self-trigger/archived guards as
direct agent mentions).

* fix: add canAccessPrivateAgent gate to squad mention branch

Closes the P1 permission vulnerability where a plain workspace member
could trigger a private squad leader by @mentioning the squad, bypassing

enforces.

Adds regression test TestCreateComment_SquadMentionPrivateLeaderBlocksPlainMember.

334d9cdd02 fix(squad): skip leader when a member @mentions anyone (MUL-2170) (#2569)
* fix(squad): skip leader on comment when a member @mentions any agent (MUL-2170)

When a human commenter routes an issue directly at a specific agent via
[@Name](mention://agent/<id>), the squad leader was still being woken up
to evaluate the same comment. The leader's only real options were to
re-delegate to the agent the member already named or to record
no_action — both of which produce queue noise without changing the
outcome.

This skips the leader-enqueue path entirely when:
  - the assignee is a squad,
  - the comment author is a member, AND
  - the comment body contains at least one agent mention.

Agent-authored comments are intentionally exempt: when an agent posts
an update that @mentions another agent, the leader still needs to
coordinate the thread. The existing leader-self-trigger guard is
preserved. Only the current comment's body is inspected — parent
(thread root) mentions are not inherited here.

Tests cover the helper (mentions parsing) plus the integration matrix:
member plain / member @member / member @non-leader-agent /
member @leader / agent @agent / leader-self.

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

* test(squad): exercise full CreateComment path for leader-skip rule (MUL-2170)

Adds an integration test that drives the HTTP-layer CreateComment handler
(not just the helper) to lock the call-site wiring: a member top-level
comment with an @agent skips the squad leader, and a subsequent plain
reply in the same thread DOES wake the leader — the parent's @agent
mention must not be inherited into the leader-skip decision.

Picks up a non-blocking review note on PR #2569.

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

* fix(squad): skip leader on any explicit member mention, not only @agent (MUL-2170)

Broaden the leader-skip rule for squad-assigned issues: a member comment
that explicitly @mentions anyone — @agent, @member, @squad, or @all —
counts as deliberate routing and the squad leader stays out. Issue
cross-references (mention://issue/...) are not routing and still trigger
the leader as before.

Per Bohan's follow-up on MUL-2170 — @member should suppress the leader
for the same reason @agent does: the human has already pointed at a
specific recipient, so a leader turn would just be observation noise.

Helper renamed commentMentionsAnyAgent → commentMentionsAnyone with
explicit handling of all four routing mention types. Existing call-site
wiring (current-comment-only, agent-author exemption, leader self-trigger
guard) is unchanged.

Tests updated and extended to cover the full routing matrix:
@member / @squad / @all / @issue (cross-ref) plus the @agent variants
already covered.
