7ebe0bf58d MUL-7213: feat(server): Triage has no executor (#8373)
* feat(server): start no run for an issue in triage (MUL-7213)

An issue waiting in Triage produces no execution run, and the triage run
itself leaves no trace an execution run can inherit.

The rule cannot be enforced at the call sites. Five paths enqueue without
looking at status at all (comment and mention dispatch, quick action,
manual rerun, auto-retry), and dispatchIssueRun discards the enqueue error
entirely, so a missed call site would fail silently. So the check sits at
the queue door — immediately before every INSERT of an issue-linked
agent_task_queue row — and the upstream short-circuits exist only so that
previews and dispatch reasons stay honest about what the door will do.

guardIssueNotInTriage covers all five insert sites: both enqueue funnels,
FailTask's in-transaction retry, the orphan sweeper's retry, and the
delegated-failure recovery dispatch. Two future paths are meant to be
exempt and both are Triage's own — the triage run, and accept, which
leaves Triage in the same transaction that enqueues the execution run.

Upstream, WillEnqueueRun, maybeEnqueueOnAssign, the two
shouldEnqueue*OnAssign gates and the comment trigger router all refuse
Triage; rerun and quick action refuse with 403 issue_in_triage, a new
dispatch reason code. WillEnqueueRun also treats leaving Triage as a
creation rather than a status change: accept is when the issue becomes
work, and the backlog-to-elsewhere rule would refuse it outright.

Two narrower rules follow. retryEligible excludes triage runs for the
reason it excludes autopilot runs: re-triaging reads the entry as it
stands now, so replaying a failed attempt is never the right recovery.
And GetLastTaskSession excludes them from all three CTEs, so the first
execution run after accept does not resume the conversation in which the
agent was still deciding whether the entry was worth keeping.

Refusals are deliberately quiet where a caller cannot act on them. The
FailTask guard never returns — that transaction also carries the parent's
failed status, and losing it would leave the task stuck in 'running'.

Verified: internal/handler, internal/service and cmd/server pass; every
new test was confirmed to fail with the change neutralized.

* fix(server): close two triage session bypasses around rerun (MUL-7213)

Review found that session isolation had two holes the query-level
exclusion could not reach, and that the two quietest queue-door paths had
no direct coverage.

A manual rerun resolves its session from the task the user named, via
rerun_of_task_id, not from GetLastTaskSession — so after accept, naming
the historical triage task reran the triager and resumed the triage
conversation, walking straight around the exclusion. RerunIssue now
refuses a triage source: redoing triage is re-triage, a different action
on a different status. rerunSourceMatchesTaskScope refuses it too, which
is what still holds for a rerun row an older server wrote mid-deploy.

GetLatestTaskRolloutMissing reports only whether GetLastTaskSession fell
back, so the two have to exclude the same rows. It did not, so a terminal
triage run with session_rollout_missing told the first execution run after
accept that it had lost the previous turn's context — about a turn it was
never entitled to.

Tests now cover the two doors that refuse silently: FailTask's
in-transaction retry, which must leave the parent failed and add no child,
and dispatchDelegatedFailureRecovery, which builds its coordinator task
with a direct CreateAgentTask call. Both assert against a positive control
so a zero cannot come from an inert fixture; the recovery test also shows
the obligation is deferred rather than dropped — the same pending comment
wakes the coordinator once the issue is accepted.

Verified: internal/handler, internal/service and cmd/server pass; all five
new tests were confirmed to fail with the fixes neutralized.

* refactor(server): let a named agent talk on a Triage issue (MUL-7213)

The rule shipped as "an issue in Triage starts no run", which is a
mechanical restatement of the product red line rather than the line
itself, and it was too wide: @-mentioning an agent to discuss a Triage
entry was refused along with everything else.

What Triage actually lacks is an EXECUTOR. Nothing may derive one from the
issue — the assignee, a prefilled owner, a squad leader, an automatic
retry — because that is exactly what the triager is still deciding, and
because prefilling an owner is how a run starts today, the triager would
otherwise dispatch the very owner it was only proposing. A person naming
an agent by hand is a different act: no triager action produces it and the
cost is one the person chose. That is the same shape as backlog, which
parks assignment but lets comments through, one notch tighter because in
Triage the assignee is only a proposal.

So the queue door now judges the run's origin rather than the funnel it
came through. OriginDerived is the zero value, so a caller that says
nothing still gets the strict answer and a new enqueue path cannot leak in
by omission; the two mixed wrappers take it as a parameter, which made the
compiler enumerate every call site.

Comment routing loses its blanket short-circuit and instead refuses the
two routes that derive an executor — the assignee fallback and the squad
leader fallback. Explicit mentions, replies to an agent, and thread
continuation route as they do anywhere else. Rerun now follows its source:
a discussion run may be repeated, naming no source means "run the assignee
again" and is refused, and the triage run itself keeps its own reason.

Assignment, quick action, auto-retry and all three session isolations are
unchanged. The delegated-failure door is gone because main's #8406 gate
subsumes it: Triage is its own lifecycle category, so it is neither
unstarted nor started and both that gate and the pending-recovery query
already exclude it. A test pins that.

Verified: internal/handler, internal/service and cmd/server pass; both
halves of the new rule were confirmed to fail when neutralized in place.

* refactor(server): hold Triage in its own column, not in status (MUL-7213)

`status` answers "how far along is this work". Triage answers "is this
work at all". Holding the second question inside the first field makes
every reader of `status` re-answer it, which is where the scattered
`<> 'triage'` checks came from — main carried 9 of them and this branch
had grown to 23. A column of its own asks it once.

issue.triage_state is NULL for an ordinary issue and `pending` for one
waiting in Triage. Adding a nullable column with no default is a
catalog-only change, so no table rewrite and no backfill; the queue reads
a partial index sized to itself rather than to the issue table.

What follows from the move:

- issuestatus goes back to 7 keys and 4 categories. Triage is no longer a
  category, a behavior, or something ExpandCategories can name, so
  CategoryForBehavior, BehaviorsForCategory, ParseCategory and
  ExpandCategories lose their special cases, and the dead board-order arm
  and status label go with them.
- WillEnqueueRun loses `acceptedFromTriage`. Accept clears a column and
  then takes the ordinary create / assign path, so there is no "was in
  triage" transition left for the predicate to recognise.
- The write lock disappears rather than narrowing. Status, project and
  parent on a Triage entry are the triager's proposal and accept is what
  confirms them, so ordinary writes reach them; the marker itself is not
  a field of the issue API, so there is nothing left to lock.
- The duplicate guards carry `triage_state IS NULL` instead of a status
  key, and the delegated-failure recovery predicate gains the same, in
  both its SQL and its Go mirror.

What does NOT follow, deliberately: the reserved NAME stays. Migration
475's CHECK is deployed and 476's renames are irreversible, so `triage`
remains unavailable as a custom status key and Resolve keeps refusing it
— one reserved word rather than five special cases. Read-path exclusion
is a separate sub-issue and is not attempted here.

Also from review: the quick-action refusal is now documented as a
first-phase product choice rather than a consequence of the rule (its
target is configured, not derived), and ErrIssueInTriage no longer claims
that nothing runs.

Verified: handler, service, issuestatus, cmd/migrate and cmd/server pass
on a database migrated from 001; every column read was confirmed to turn
its own tests red when neutralized. cmd/migrate's concurrent-index
convention test caught a missing cleanup hook for the new index.

* fix(server): hold the parent of a Triage entry (MUL-7213)

Removing the write lock went one field too far. Status, project, assignee
and the rest on a Triage entry are the triager's proposal and accept
confirms them, so those writes belong. The parent is not a proposal:

- the routing panel has no parent field. "Merge into an existing issue"
  links rather than re-parents, so a Triage entry hanging off a parent is
  a half-state the product never asks for;
- a child in Triage carries a proposed status, so it is never terminal.
  stageBarrierClosed would wait on it forever — holding the whole sibling
  set, or one stage's frontier — and ChildIssueProgress would count it in
  the denominator. Both reach it through parent_issue_id, so refusing the
  write is what keeps them out of reach. That is behavior, not display,
  and it is why this one is worth a lock rather than a read-path filter.

UpdateIssue and batch refuse a request that carries parent_issue_id for
an issue in Triage, with or without a value: null clears, which is
equally a parent decision the triager does not get to make. The batch
asks one count rather than listing statuses, since "any" is all it needs.

Verified: handler, service, issuestatus, issueguard, cmd/migrate and
cmd/server pass; both new tests were confirmed to fail with the guard
neutralized.

* fix(server): drop the triage case from the handoff predicate (MUL-7213)

MUL-7379 (#8435) landed on main while this branch was open and added
issueStatusIsHandoff with a `triage` case, resting on Triage resolving to
a category of its own without a catalog read. Once Triage stops being a
status that resolution is gone, so the call errors on a value no issue can
hold any more.

The case is removed rather than repaired: a Triage entry carries whatever
status the triager has proposed and is answered on that. Suppressing
notifications for Triage entries is a different rule and belongs to
MUL-7219 — the status model was giving it incidentally, and that was never
the mechanism the design asks for.

Verified on a database migrated from 001: cmd/server, internal/handler,
internal/service, internal/issuestatus and cmd/migrate pass.

* chore(db): renumber the triage migrations past the telemetry batch (MUL-7213)

MUL-7236 (#8252) took 479-482 on main while this branch was open, so both
triage migrations collided. 483 adds issue.triage_state, 484 builds its
partial index; the concurrent-index cleanup hook moves with it.

Verified on a database migrated from 001 with the new numbering.

f1ce9d4542 MUL-6883 perf(server): stop rescanning settled delegated-failure recoveries (#7820)
* feat(server): retire settled delegated-failure recoveries from the outbox scan

ListPendingDelegatedFailureRecoveries had no indexable notion of a finished
recovery. Its partial index (343) selected every recovery comment ever
written, so each sweeper tick re-proved through four joins and two NOT EXISTS
subqueries that history was already handled. LIMIT bounds the rows RETURNED,
never the rows CHECKED, so a tick that found nothing still grew more expensive
as history accumulated.

Add comment.recovery_settled_at and a partial index that holds only unsettled
recovery comments, and write the marker inside the transaction that makes a
task terminal. Every other exclusion the scan applies is reversible — an issue
can leave 'done', a cancelled retry can be superseded — so none of them can be
frozen into an index predicate. A delivery receipt on a terminal task cannot be
taken back, which is what makes it safe to record as durable state.

The marker is deliberately written only once the task is terminal.
SetTaskDeliveredCommentIDs replaces rather than appends a receipt while a task
is still dispatched, so a reclaim by a differently-capable daemon can drop an
id it will not deliver; settling at receipt-write time would freeze that
legitimate transient window into a permanently lost recovery. Exhaustion is the
one terminal outcome whose receipt lands on a row that may still be running, so
it retires the comment directly in the same transaction.

An unmarked row is the safe direction: it is scanned exactly as it was before
this column existed. That is what makes the rolling-deploy window harmless —
an older replica that writes a receipt without the marker only leaves work for
the backfill.

Co-authored-by: multica-agent <[email protected]>

* feat(server): backfill delegated-failure recoveries settled before the marker

The marker only covers tasks that reach a terminal status after the writing
code ships. History written before that keeps matching the unsettled index
predicate and keeps being re-checked on every sweeper tick, which is the cost
this change set exists to remove.

The walk retires a candidate only when a terminal task already recorded it in
delivered_comment_ids — the same monotonic condition the runtime path uses.
Its keyset watermark advances over every candidate EXAMINED rather than every
candidate marked: a recovery that is genuinely still pending must be left
alone, and keying on updated rows would hand back the same watermark forever
and never terminate.

Separate from migrations and startup, in the shape the other backfill commands
already use, so a large comment table cannot block a deploy. Running it is a
performance recovery step, not a correctness step — until it finishes the scan
behaves exactly as it does today.

Co-authored-by: multica-agent <[email protected]>

* fix(server): close the review gaps in the settled-recovery backfill and paths

Three fixes from review.

1. The backfill reproduced the bug it was written to fix. Its keyset ordered by
   id while idx_comment_delegated_failure_unsettled is (created_at, id), so the
   candidate scan read every unsettled row and sorted it to return LIMIT of
   them; and the receipt test ran a per-candidate EXISTS over agent_task_queue,
   the largest table in the database. The keyset now matches the index, and the
   receipt lookup is inverted into one agent_task_queue read per BATCH that
   hash-joins delivered ids back against the candidates.

   Measured on 500k comments / 200k tasks / 50k unsettled recoveries:
   17,393ms and 816,963 temp blocks before, 235ms and no temp spill after. The
   candidate scan goes from reading 50,000 rows to reading the 1,000 it needs.

   Total walk time is flat across batch size (50x228ms, 10x1016ms, 5x2199ms —
   all ~11s), so batch size only trades how long one statement holds row locks.
   1000 stays, now for a measured reason rather than a guessed one.

2. Bulk cancellation paths could strand a delivered receipt permanently
   unsettled, which lets the new index regrow the history it exists to remove.
   Manual rerun's pending-slot clear and agent archive were the two named in
   review; auditing the rest found comment-edit cancellation, both chat-session
   cancellations, workspace revoke and runtime teardown in the same position.
   All now settle — inside the caller's transaction where one exists, and
   through CaptureCancelledTasks for bulk paths that finalize outside one. The
   invariant is stated on the exported helper so the next such path has
   somewhere to read it.

3. --max-batches could not actually resume. The watermark lived only in the
   process, so a bounded rerun restarted at the front of the index — which is
   precisely where the rows this walk never settles live, so repeated bounded
   runs would rescan the same prefix and never reach the settleable history
   behind it. Adds --checkpoint-file (atomic replace, read on start) and
   explicit --after-created-at/--after-id, and logs the resume cursor on every
   exit path including SIGTERM.

* fix(server): make delegated-failure settlement terminal-checked and atomic

Two fixes from review.

1. The settlement SQL trusted its caller. "A delivery receipt is only immutable
   once the task is terminal" is the safety premise of the whole design, but the
   exported helper enforced nothing: passing a dispatched or running task would
   settle a receipt a reclaiming daemon can still replace, and the marker is
   monotonic, so nothing could undo it. The predicate now lives in the SQL, so a
   non-terminal task updates no rows instead of destroying the obligation.

2. Bulk settlement was post-commit best-effort, and the comment claiming the
   sweeper would replay a failed one was simply wrong: the covering task is
   terminal and already holds the receipt, so ListPendingDelegatedFailureRecoveries
   excludes the comment. It would neither replay nor settle — it would sit in
   the partial index forever, restoring the unbounded scan this change set
   removes.

   Every terminal write now commits with its settlement. CancelTasksForIssue /
   ForAgent / ByTriggerComment and the rerun pending-slot clear run in a
   transaction; CancelQueuedChatTasks settles inside the one it already had; the
   sweeper and daemon-recovery bulk fails move behind TaskService wrappers that
   own the transaction; agent archive gets CancelTasksForArchivedAgent, which
   cancels and settles atomically while still skipping the per-task broadcast
   the archive event makes redundant.

   BroadcastCancelledTasks, CaptureCancelledTasks and HandleFailedTasks run
   after their caller committed, so they no longer settle at all — a failure
   there could be neither rolled back nor repaired. The best-effort helper is
   deleted rather than left available; every remaining call site passes a qtx.

Tests: a dispatched/running task with a receipt is not settled (fails without
the SQL predicate), a bulk cancel whose settlement fails rolls the cancel back,
and the archive path settles through its atomic entry point.

Co-authored-by: multica-agent <[email protected]>

* docs(server): correct settlement invariant comment and drop leaked test function

The SettleDeliveredDelegatedFailureRecoveries doc still described the
pre-fix contract — settlement reachable through CaptureCancelledTasks or a
post-commit best-effort call — which is exactly the shape the atomicity fix
removed. Restate the rule as it now stands (same qtx as the terminal write,
never from a post-commit helper) so the stale text cannot guide a future
change back into stranding rows in the partial index.

TestBulkCancelRollsBackWhenSettlementFails dropped its trigger but left
reject_recovery_settlement() behind in the shared test database; drop the
function too.

Bohan Jiangandmultica-agent eea687d461 MUL-5686: fix(chat): resume the cancelled turn's session instead of starting cold (#6352)
* fix(chat): resume the cancelled turn's session instead of starting cold

Stopping a chat turn the agent had already begun answering, then sending
the next message, produced a reply with no memory of the conversation.

The cancelled turn's provider session is real and recorded — the daemon
pins it onto the task row mid-flight and cancellation keeps it there —
but nothing could hand it back:

  - GetLastChatTaskSession / GetLastTaskSession only considered
    'completed' and 'failed' rows, so a cancelled row's session was
    invisible to resume resolution;
  - chat_session.session_id is written only by CompleteTask / FailTask,
    and a cancelled task reaches neither: the daemon discards its result
    and sends a cancel-ack. On a chat whose first turn was cancelled the
    pointer therefore stayed NULL and the next turn started cold, since
    buildChatPrompt injects only the current user message.

Let cancelled rows into both resume lookups, and advance the chat-level
pointer at cancel time so a provider that mints a new session id per
resume does not rewind past the cancelled exchange. The mid-flight pin
may now also fill an EMPTY session slot on a just-cancelled row, which
is what a Codex pin waiting on its rollout needs when the cancel wins
the race; occupied slots and completed/failed rows stay untouchable.

Retired sessions, poisoned-failure filters and the rollout-present guard
are unchanged. A transcript killed mid-tool-call that the provider later
refuses is still caught by taskfailure.UnresumableHistory, which retires
the session and starts the next turn fresh.

Fixes #6340

Co-authored-by: multica-agent <[email protected]>

* fix(chat): close the two cancel/pin races on the chat resume pointer

Review found the pointer advance had the same shape of hole it was meant
to fix, on both sides of the cancel.

1. The status flip and the pointer advance were separate statements. In
   the gap the row is already `cancelled` while the pointer still names
   the PREVIOUS turn, so a follow-up the user had queued could be claimed
   there and resume the older session — and a failed pointer write only
   logged, still reporting the cancel as successful. Both now commit in
   one transaction and the error propagates.

2. The mid-flight pin may land AFTER the cancel (for Codex it waits for
   the rollout), so the cancel transaction sees no session to publish and
   the pin only fills the task row. On a chat that already had history
   the stale pointer kept shadowing it, which is precisely the case the
   pin change was added for.

Both paths now run one guarded statement,
AdvanceCancelledChatSessionPointer. It reads the task row itself rather
than trusting an in-memory copy, ignores anything that is not a cancelled
chat task, and refuses to move the pointer when a NEWER task on the chat
already recorded a session — so a straggler pin cannot drag the
conversation back onto the interrupted turn.

Regression tests, both failing before this commit: a cancel whose pointer
write is blocked must not expose `cancelled` to another connection, and a
late pin on an already-cancelled row must reach the next real claim. The
newer-turn guard is covered too.

Co-authored-by: multica-agent <[email protected]>

* fix(chat): make the pin atomic and restore the chat->task lock order

Second review round found the remaining half of the same class of bug.

1. PinTaskSession still committed the session onto the task row and
   advanced the chat pointer as two statements, and the pointer failure
   only logged while the endpoint still answered 204. A follow-up claimed
   in that window resumes the previous turn — the exact case the pin
   change was added for. Both writes now share one transaction and every
   failure is reported.

2. Adding the pointer write gave the cancel transaction two rows to hold,
   and it took them in the wrong order: agent_task_queue first, then
   chat_session. DeleteChatSession takes them the other way round, so the
   two could deadlock (40P01, and runInTx has no deadlock retry). The
   repo's documented order is chat_session -> agent_task_queue; both the
   cancel and the pin now open with LockChatSessionForTask, the same
   helper FinalizeDeferredCancelledChat uses. ErrNoRows there means a
   non-chat task or an already-deleted session — nothing to lock and
   nothing to advance.

Regression tests, all three failing before this commit (the concurrency
one with a real `deadlock detected`): the pin must not expose a session
on the task row while its pointer write is blocked; a cancel waiting on
the chat session must hold no lock on the task row (FOR UPDATE NOWAIT
probe); and cancel racing a chat delete must never come back with 40P01.

Co-authored-by: multica-agent <[email protected]>

* fix(chat): put every chat-task terminal write behind the same lock order

The cancel and pin paths took chat_session before agent_task_queue; the
terminal reports still took them the other way round, so the two could
deadlock (40P01) — reproduced deterministically as cancel-vs-complete.
Choosing per-path was never going to work: either every writer that holds
both rows agrees on an order or none of them are safe.

CompleteTask, FailTask and the cancelled-chat finalize now open with the
same LockChatSessionForTask the cancel, pin, DeleteChatSession and
FinalizeDeferredCancelledChat paths use, via a shared helper that
documents the invariant in one place.

Also de-flakes the concurrency tests this PR added. They held a row lock
and then read other rows on a FRESH pooled connection; the suite shares
one database, so a sibling package's DDL could queue an ACCESS EXCLUSIVE
request in between, park our later ACCESS SHARE request behind it, and
wedge the package until the 10-minute timeout (observed in a parallel
`go test ./internal/...` run). Those transactions now take their table
locks up front and read on the connection that already holds them, and
every racing call is bounded so a stall fails loudly instead of hanging.

Regression tests, all failing before this commit: complete and fail must
hold no lock on the task row while waiting for the chat session (FOR
UPDATE NOWAIT probe), and cancel-vs-complete plus pin-vs-fail must never
come back with 40P01.

* test(chat): fail the race tests on any unexpected error, bound every call

Review nits on the concurrency tests.

Matching only *pgconn.PgError(40P01) let the pin side through: a pin that
loses a deadlock is reported by the HTTP handler as a plain 500 with no
PgError to unwrap, so the check skipped exactly the failure the test
exists for. Both racers now fail on anything except the one benign
outcome — whoever finalized the task first leaves the loser matching no
row (pgx.ErrNoRows).

The remaining racing calls still used an unbounded context.Background(),
which this PR had already claimed were bounded. They now share the same
raceTimeout as the rest.

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.

Co-authored-by: multica-agent <[email protected]>

* 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

* 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.

Co-authored-by: multica-agent <[email protected]>

* 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).

Co-authored-by: multica-agent <[email protected]>

* 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).

Co-authored-by: multica-agent <[email protected]>

* 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.

Co-authored-by: multica-agent <[email protected]>

* 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).

Co-authored-by: multica-agent <[email protected]>

* 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 <[email protected]>

* 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 <[email protected]>

* 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 <[email protected]>

* 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.

Co-authored-by: multica-agent <[email protected]>

* 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.

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

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

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

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

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

Address second-round review feedback from PR #3428:

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

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

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

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

Bohan Jiangandmultica-agent b7082a01f1 fix(issues): retry button targets the row's agent (MUL-2457) (#2921)
* fix(issues): retry button targets the row's agent, not the assignee (MUL-2457)

The execution log retry button used to re-fire the issue's current
assignee instead of the agent that actually ran the clicked row. After
a reassignment, or for squad workers / @-mention agents, the rerun
landed on the wrong agent.

POST /api/issues/{id}/rerun now accepts an optional task_id: when set,
the rerun targets that task's agent (and reuses its leader/worker
role). An empty body keeps the assignee-driven CLI/API contract.

The execution-log retry button passes task.id, so per-row retry always
fires the correct agent. enqueueMentionTask gained a forceFreshSession
parameter so the new mention-path rerun keeps the same fresh-session
contract as the assignee path.

* fix(issues): inherit trigger provenance + fix cross-issue test (MUL-2457)

Address review feedback on PR #2921:

1. RerunIssue now inherits TriggerCommentID from the source task when
   sourceTaskID is valid. Without this, a per-row rerun of a comment-
   or mention-triggered task degrades into a generic issue run because
   the daemon's buildCommentPrompt path keys on TriggerCommentID. The
   inherited summary is rebuilt naturally inside the enqueue helpers
   (buildCommentTriggerSummary derives it from the comment ID).
2. The new cross-issue rejection test inserted a second issue without
   `number`, hitting uq_issue_workspace_number on a same-workspace
   collision with the fixture's issue. Both inserts now claim the next
   available per-workspace number (MAX(number)+1) — matching the
   pattern used by notification_listeners_test.

Added TestRerunIssueInheritsTriggerCommentFromSourceTask to lock the
trigger provenance contract.

Bohan Jiangandmultica-agent b17f975a17 docs(cli): clarify issue rerun semantics (current assignee, fresh session) (#2304)
* docs(cli): clarify `issue rerun` semantics

The CLI table described `multica issue rerun <id>` as "Rerun the most
recent agent task", which led users to expect it would re-run whichever
agent ran last. The actual behavior is to enqueue a fresh task for the
issue's **current** agent assignee, regardless of who ran most
recently — see `TaskService.RerunIssue` in
`server/internal/service/task.go`.

Also fix a stale claim in `tasks.mdx`: the "Manual rerun" section
described session inheritance as "Yes", but commit b1345685 made manual
rerun pass `force_fresh_session=true` precisely to avoid replaying a
poisoned session. Only **automatic retry** still inherits the session.

Updates EN + ZH mirrors of `cli.mdx` and `tasks.mdx`.

* docs(tasks): tighten rerun trigger surface; clean stale Go comments

Apply review feedback on PR #2304:

- `tasks.mdx` / `tasks.zh.mdx`: rerun is triggered via CLI or the
  `/api/issues/{id}/rerun` endpoint, not "UI or CLI" — there's no rerun
  affordance in web/desktop today.
- `tasks.mdx` / `tasks.zh.mdx`: comparison table — manual rerun applies
  to "Issues with an agent assignee", not "All sources". The handler
  rejects with `issue is not assigned to an agent` for anything else,
  and there's no rerun path for chat or autopilot tasks.
- `task_lifecycle.go`: `RerunIssue` doc comment claimed the new task
  "carries the most recent session_id/work_dir so the agent can resume".
  That has been false since b1345685 — rewrite to reflect the actual
  `force_fresh_session=true` contract.
- `agent.sql` (regenerated `agent.sql.go`): `GetLastTaskSession` doc
  said it serves "auto-retry / manual rerun"; manual rerun is now
  routed around it via `force_fresh_session=true`. Note both the
  auto-retry path it does serve and the rerun escape hatch.

No logic change.

LinYushenandCopilot 0b1333fb00 feat(server): orphan-task recovery + auto-retry + manual rerun (MUL-1128) (#1476)
* feat(server): orphan-task recovery + auto-retry + manual rerun (MUL-1128)

When the daemon process crashed mid-task the issue was stuck at
in_progress for up to 2.5h: the in-flight task timeout was the only
mechanism that ever moved the row, and the runtime heartbeat sweeper
only fires after the runtime stays offline for 45s — a quick restart
beats both windows.

This change implements the A+B plan from the issue thread:

A. lifecycle hygiene
- migration 055 adds attempt / max_attempts / parent_task_id /
  failure_reason / last_heartbeat_at to agent_task_queue
- new daemon-auth endpoint POST /runtimes/{id}/recover-orphans:
  daemon calls it on every register so the server fails any
  dispatched/running tasks the previous process left behind
- new daemon-auth endpoint POST /tasks/{id}/session: persists the
  agent's session_id + work_dir mid-flight so a crash doesn't
  lose the resume pointer (claude+codex emit MessageStatus with
  SessionID; daemon forwards on the first one it sees)
- FailAgentTask / FailStaleTasks / FailTasksForOfflineRuntimes
  now set failure_reason ('agent_error' / 'timeout' /
  'runtime_offline')

B. auto-retry with resume context
- TaskService.MaybeRetryFailedTask spawns a fresh queued attempt
  carrying parent's session_id/work_dir when the failure reason
  is infrastructure-shaped (timeout, runtime_offline,
  runtime_recovery) and attempt < max_attempts; skips autopilot
- wired into the runtime sweeper paths and TaskService.FailTask
  so the user transparently sees a new in_progress run instead of
  a stuck row
- new user-auth POST /api/issues/{id}/rerun + multica issue rerun
  CLI for the manual escape hatch

* fix(server): address PR review for orphan-task recovery (MUL-1128)

Three review-must-fix items on top of the A+B implementation:

1. recover-orphans now funnels through TaskService.HandleFailedTasks,
   the same shared post-failure pipeline used by the runtime sweeper.
   This guarantees task:failed events are emitted, agent status is
   reconciled, and issues stuck in_progress with no remaining active
   task are reset to todo even when no auto-retry is created
   (max_attempts exhausted, autopilot, non-retryable reason).

2. RerunIssue now uses CancelAgentTasksByIssueAndAgent, scoped to the
   issue's current assignee. The previous implementation called
   CancelAgentTasksByIssue, which would collateral-cancel parallel
   @-mention agents on the same issue.

3. GetLastTaskSession now considers both completed and failed tasks
   (mirroring GetLastChatTaskSession), ordering by the most recent
   timestamp. With UpdateAgentTaskSession pinning session_id/work_dir
   mid-flight, an auto-retry or manual rerun of a daemon-crash failure
   now actually resumes the prior conversation context instead of
   starting fresh — matching the stated B-branch behaviour.

go build / go vet pass; the existing service and agent test suites pass.
runtime_sweeper / handler integration tests require a local DB with the
055 migration (and the pre-existing 050 first_executed_at column).
