4d0475ce89 feat(usage): error/failure charts on the Usage page (MUL-5352) (#5991)
* feat(usage): add error/failure visibility to the Usage dashboard

The Usage page could only answer "how much did we spend"; nothing on it
showed how often agents fail, what kind of failure it was, or which agent
is responsible. Operators had to open failed tasks one at a time to spot a
pattern.

`agent_task_queue.failure_reason` already carries the refined 21-value
taxonomy from server/pkg/taskfailure, so this is a read path over data that
already exists.

Backend — two rollups, both scoped by workspace/project/window like the
existing dashboard endpoints:

  GET /api/dashboard/failures/daily     per-(date, failure_reason)
  GET /api/dashboard/failures/by-agent  per-(agent, failure_reason)

They return every terminal task, not just failures: the `failure_reason: ""`
row carries the succeeded count. That is what makes the error rate's
denominator share filters with its numerator. The run-time rollups can't
serve as that denominator — they require `started_at IS NOT NULL`, so a task
that expired in the queue (the signature of a runtime outage) contributes
nothing to their failed_count. A failed row with an empty reason column
lands in an `unclassified` bucket rather than being mistaken for a success.

Frontend:
- "Errors" joins the trend toggle, daily and weekly, stacked by failure
  class with the bucket's error rate in the tooltip.
- An Errors card breaks the window down by class and by agent, with the raw
  failure_reason strings behind a disclosure (unlocalised — an operator
  pastes them into a log search). Each agent row links to its Work tab,
  which lists the actual failed runs.
- The 21 backend reasons fold into 7 display classes in
  @multica/core/dashboard. Unknown reasons — including ones from a backend
  newer than the client — land in "other" instead of being dropped, so the
  class totals always reconcile with the failure count.

The Tasks KPI tile is deliberately left alone: its value counts started
tasks only, so quoting the failure rollup's larger count there would put two
denominators in one tile. The Errors card states its rate with the
denominator spelled out instead.

Migration 225 adds a partial index on agent_task_queue(completed_at) for
terminal statuses. The table had no completed_at index at all, so the two
pre-existing run-time rollups were already scanning it; these two new
queries would have doubled that.

Closes #4429 (MUL-5352)

* fix(usage): correct the Errors drill-down, window and agent exposure

Review findings on PR #5991.

1. The drill-down pointed at the wrong page. `?view=work` renders
   ActorIssuesPanel — the issues assigned to the agent — while its runs live
   in the Overview pane's ActivityTab. Link to Overview.

   That page also could not show why a run failed: `failureReasonLabel` was a
   `Record<TaskFailureReason, string>` indexed with a cast to the old 6-value
   coarse enum, so every refined reason the backend has written since
   MUL-1949 resolved to `undefined`. It is now a function over the full
   21-value taxonomy plus the legacy coarse values, falling back to the raw
   wire string for anything newer than the client. Fixes the issue execution
   log too, which had the same cast.

2. The Errors card covered one more calendar day than the chart above it.
   `parseSinceParamInTZ` returns N+1 days of headroom on purpose and the
   dashboard trims the surplus client-side — but only a series carrying a
   date can be trimmed that way. Totals / classes / reasons now derive from
   the date-bucketed rollup after that trim, and the per-agent rollup (which
   has no date to trim on) closes its window server-side via a new
   `parseExactSinceParamInTZ`. At days=1 the card previously reported
   yesterday's failures beside a chart showing none.

3. The top-offenders list leaked agents the viewer cannot see. The failure
   rollups are workspace-scoped and deliberately skip per-agent visibility,
   but the agent list they are joined against does not — members only see a
   private agent when they own it or are owner/admin. `name ?? row.agentId`
   therefore rendered a bare UUID along with that agent's failure count,
   rate and dominant error class. Unresolvable agents now fold into one
   anonymous row, and the renderer never falls back to an id. Stricter than
   `bucketUnknownAgentRows` while the agent list loads: a transient flash of
   UUIDs is the leak, not a cosmetic glitch.

Also from the review: the Errors tooltip echoed the raw Recharts dataKey
("rate_limit") instead of the translated label the legend already carries.

Not changed — the schema's `failure_reason` default stays `""`. Defaulting a
missing field to a failure bucket guards against a deflated rate, but the
realistic drift is `omitempty` on the Go struct tag, which would strip the
field from exactly the SUCCESS rows and read as a 100% error rate. Added
TestDashboardFailureWireContractKeepsEmptyReason to pin that the server
always emits the field, which is the assumption the default rests on.

* fix(usage): renumber migration and fix the anonymous bucket's failure class

Review findings on PR #5991, round 2.

1. Migration prefix 225 collided with `225_chat_message_channel_media_pending`,
   which landed on main while this branch was open — backend CI failed on
   TestMigrationNumericPrefixesStayUniqueAfterLegacySet. Merged main and
   renumbered to 231; main now carries 225 through 230, so 226 is taken too.

2. The anonymous "Other agents" bucket could announce the wrong failure class.
   It merged rows that had ALREADY collapsed to one dominant class per agent,
   then credited each agent's entire failure count to that class. An agent
   failing auth 6 / timeout 5 contributed 11 to auth and 0 to timeout, so a
   bucket whose real composition was timeout 15 / auth 6 rendered as Auth.

   Fixed by anonymizing the raw per-(agent, reason) rows instead: the sentinel
   becomes just another agent_id and `aggregateAgentFailures` computes its
   classes from real counts. That also deletes the parallel bucketing pass —
   one identity rewrite replaces it. `knownAgentIds` moves up to where both
   consumers can see it.

Also from the review:
- The wire-contract test decoded both payloads into one map. json.Unmarshal
  merges into a non-nil map rather than resetting it, so a residual
  failure_reason from the first case could have masked an omitempty
  regression in the second — exactly what the test is meant to catch. Now
  table-driven with a fresh map per case.
- A test comment still described the drill-down as pointing at the Work tab.

60048172a7 fix(lark): ingest inbound images and videos as chat attachments (MUL-4934) (#5580)
* fix: ingest feishu media as chat attachments

* fix: ingest feishu post embedded media

* fix(lark): make inbound media retries safe

* fix lark media resource limit

* fix(lark): move inbound media off ack path

* fix(channel): make inbound media runs durable

* fix(channel): close enqueue-vs-append race on media deferral

EnqueueChatTask read the session-wide media deadline in one statement and
sealed the input batch in a later one. Under READ COMMITTED a media message
committing between the two got sealed into a task the deadline read had
already decided was 'queued', so the daemon could claim it before its
attachment bound — the agent received the bare placeholder, and the later
media-ready promotion was a no-op against a non-deferred task.

After the seal, re-derive the deferral from the sealed batch itself in the
same transaction (DeferChatTaskForSealedPendingMedia): if any sealed message
still carries an unexpired media marker, flip the task to deferred with
fire_at aligned to the latest marker. The existing post-commit promote fence
already covers the opposite direction (marker cleared mid-transaction).

Adds a deterministic regression test that injects the media append between
the deadline read and the seal via a wrapped pgx.Tx.

* fix(channel): keep committed chat task out of enqueue error path

The post-commit media-ready fence returned its error from EnqueueChatTask
even though the deferred task was already durably committed. The router
flush treats any enqueue error as "no task exists": it clears the typing
indicator and logs an enqueue failure while the run still happens at its
fire_at deadline. Log the fence failure instead — the claim-path deferred
promoter re-queues the task regardless.

* fix(channel): cap global media resolution concurrency

Media jobs were serialized per session but unbounded across sessions: a
burst could open arbitrarily many concurrent 45s Lark downloads, and each
unknown-length upload may buffer up to the 100 MiB resource cap in memory.
Gate resolveAndBindMedia behind a global slot semaphore (default 8,
RouterConfig.MediaConcurrency). Per-session ordering is unchanged; on
shutdown a job cancelled while waiting for a slot proceeds straight to the
bounded DB finalize so marker clearing stays prompt. Also document that the
per-message media budget spans queue/slot waits (it must match the
persisted fire_at) and why timed-out uploads cannot leak unbounded orphans.

* fix(chat): keep channel-sealed user messages on task cancel

Sealing the channel input batch stamps task_id onto channel user
messages, which exposed them to the cancel draft-restore path: an
empty-transcript cancel would DeleteUserChatMessageByTask the sealed
Feishu/Slack messages and detach their attachments. Those messages are
the durable record of what the platform sender wrote — the sender has
no Multica composer to restore a draft into.

Gate the restore-delete on ChatSessionHasChannelBinding in both the
synchronous finalize and the deferred finalize (the latter covers
markers left by an older replica during a rolling deploy); a bound
session now settles as "Stopped." instead.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(channel): skip the media pipeline for messages without media

Every inbound message on a Media-enabled platform persisted a 45s
media deadline and queued a resolution job, so a plain text message
could wait behind the global media semaphore (its task deferred while
other sessions download 100 MiB videos) and a crash between append and
clear delayed a pure-text run to the full 45s fallback.

Add MediaResolver.HasMedia — a pure in-memory probe the Router calls
on the ACK path — and only persist the deadline / enqueue the job when
the message actually references platform media. The Feishu resolver
decodes the already-received payload and reports standalone image or
video keys and post-embedded img/media spans.

* fix(chat): gate cancel restore on immutable channel provenance

The previous guard keyed the cancel restore-delete off
ChatSessionHasChannelBinding, but a binding only proves routing exists
right now: archiving a session and rebinding an installation both
delete the binding while preserving chat history, so a still-cancellable
sealed task could again restore-delete the original inbound messages.

Persist provenance on the message instead: migration 203 adds
chat_message.channel_ingested, stamped inside the channel append
transaction and never mutated, and both cancel finalize paths now gate
on TaskHasChannelIngestedMessages over the task's sealed batch. The
binding-existence query is removed. Regression tests cover ingest ->
archive/unbind -> cancel for a queued and a started task.

* fix(channel): reclaim media uploads that never gain an attachment row

Deadline expiry dropped already-resolved refs and a BindMedia failure
was log-only, leaving uploaded objects with no attachment row and no
reclaim path — the dedup mark commits with the message before media
runs, so a redelivery is dropped as a duplicate and never re-resolves
(and thus never overwrites) those keys, and workspace/session deletion
only enumerates the attachment table.

Add MediaResolver.DiscardMedia — a best-effort delete by StorageKey —
and call it from both failure paths in resolveAndBindMedia. The Feishu
resolver forwards to the storage backend's Delete. Tests cover a
partial upload discarded at the deadline, discard on bind failure, and
key-level deletion in the resolver.

* docs(server): refresh comments stale after detached media ingestion

Channel tasks now seal a self-owned input batch, media ingestion is no
longer out of scope for the flattener, and MediaRefs are filled by the
detached resolver after append rather than by feishuChannel pre-engine.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(chat): stop keying channel empty-completion silence off chat_input_task_id

Sealing gave channel tasks a self input-owner, which broke
writeChatCompletionOutcome's discriminator: it treated any owned task
as direct, so an empty channel completion wrote the no_response
fallback row and the outbound patcher — which forwards any non-empty
chat:done content verbatim — pushed the English fallback body to
Feishu/Slack, violating the MUL-4351 contract.

Silence is now decided by the immutable channel_ingested provenance of
the task's input batch, looked up by the batch OWNER id
(chat_input_task_id): auto-retry clones inherit the owner while their
sealed messages stay tagged with the parent's id, so keying off the
task's own id would misread a channel retry as direct. The cancel-path
provenance gates switch to the same owner key via chatInputOwnerID.
chat_input_task_id is back to meaning only "input batch owner".

* chore(migrations): renumber to 203/204 after upstream took 202

Upstream main merged 202_runtime_profile_add_qwen while this branch
held 202/203, tripping TestMigrationNumericPrefixesStayUniqueAfterLegacySet
on the CI merge tree. channel_media_pending becomes 203 and
channel_ingested becomes 204; no content changes.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(channels): gate outbound delivery on channel provenance, not owner

Merging main brought #5645 (keep direct chat replies in Multica),
whose outbound gate assumed channel tasks leave chat_input_task_id
NULL. Sealed channel tasks own an input batch too, so on the merge
tree every channel reply and failure notice was classified as direct
and silently dropped — agents stopped replying in Feishu/Slack.

Both outbound gates now call engine.TaskInputIsChannelIngested: a NULL
owner keeps #5645's deliver-by-default for pre-sealing tasks, an owned
batch delivers only when it carries the immutable channel_ingested
stamp (keyed by the owner id, so auto-retry clones inherit the
verdict). Direct replies stay in Multica; sealed channel replies reach
the platform. Tests cover both directions on both platforms.

* fix(channel): discard media orphans on a fresh context, after finalize

DiscardMedia shared finalizeCtx with BindMedia, so a bind that failed
because the finalize deadline expired handed the storage deletes an
already-dead context — the compensation silently no-opped and the
orphans leaked anyway. The deadline path also ran S3 deletes before
the marker clear, eating the same 5s budget the user-facing
bind/promotion needed.

Collect the refs from both failure paths, run bind + promotion on the
finalize budget first, then delete on a fresh discard context. The
bind-failure test now pins that discard receives a live context.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(channel): compensate result-uncertain media uploads and commits

The compensation protocol treated "the call returned an error" as "the
side effect did not happen", which is wrong in both directions across
the result-uncertain windows:

- An upload error can follow a server-side write (lost response,
  deadline mid-write). The attempted key never reached the router, so
  nothing could reclaim it and dedup guarantees no re-resolve. The
  resolver now idempotently deletes the deterministic key on a fresh
  budget right at the failure site.

- A commit error is not a rollback guarantee: a lost ack can report
  failure after Postgres durably committed the attachment rows, and
  the router's discard would then delete objects those rows reference.
  BindMediaRefs now converges the ambiguity on a fresh budget — any of
  the batch's URLs present proves the atomic commit landed (bind
  reports success); none proves the rollback (discard stays safe); a
  failed verification returns ErrMediaBindResultUnknown and the router
  keeps the uploads, preferring a rare orphan over a broken attachment.

Fault-injection coverage: an upload error deletes the attempted key; a
lost-ack commit keeps the bound attachment and reports success; a
verified rollback stays a discardable error; the router keeps uploads
on the unknown-outcome sentinel.

* feat(channel): replace inline media compensation with an intent ledger and reconciler

Inline best-effort compensation cannot answer "did my side effect
happen?" at the moment it needs the answer — the DELETE/PUT reordering
and the empty-read-vs-in-flight-COMMIT gaps were both instances of the
same two-system atomicity problem. Persist the intent instead and let
an asynchronous reconciler settle it:

- channel_media_pending_object (migration 214; claim index 215 as its
  own single-statement CONCURRENTLY migration): a state machine row
  ('pending' -> 'deleting') with lease, attempt, and backoff columns.
- The resolver upserts the row BEFORE each PUT, state-guarded so a key
  the reconciler owns is never resurrected (the resource is skipped).
  ObjectURL is a pure function of configuration, so the row carries the
  attachment URL pre-upload.
- BindMediaRefs deletes the batch's rows INSIDE the attachment-insert
  transaction: commit landed <=> intents gone, atomically, so an
  ambiguous COMMIT never needs adjudication. A key already claimed to
  'deleting' is skipped (placeholder stays).
- Nothing is ever deleted inline. The reconciler — an independent
  worker so storage latency cannot starve other sweepers — claims due
  rows ('pending' past the settle delay, or expired leases) under a
  fresh lease, checks for a durable attachment reference only AFTER the
  claim (race-free: bind can no longer succeed on the key), deletes
  unreferenced objects outside any transaction, and backs off failed
  deletes with attempt-based retry. Crash windows converge for free.
- The settle delay is a fixed constant carrying NO correctness weight;
  invariant tests pin it at >=10x every pipeline budget. Metrics cover
  deletes, referenced clears, delete failures, and ledger backlog.

Removed: MediaResolver.DiscardMedia, ErrMediaBindResultUnknown, the
post-commit verification, and both router discard branches.

Tests: intent-before-upload ordering; upload error leaves the row and
deletes nothing; bind-wins vs reconciler-wins on the same key; lost-ack
and rolled-back commit injections (intent cleared iff the attachment
landed); reconciler three-state settle; expired-lease reclaim; delete
failure backoff and retry; settle invariants.

* fix(channel): never build or sweep the media reconciler without storage

store is nil when S3 is unconfigured AND the local upload dir fails to
initialize, but the reconciler was constructed unconditionally and
main only gates the goroutine on the reconciler pointer — the first
unreferenced ledger row (rows can pre-exist from a boot where storage
worked) would nil-pointer panic a bare goroutine and take down the
process.

Construct the reconciler only when a storage backend exists, and guard
RunOnce defensively: with no deleter it skips the sweep without
claiming, so rows are not stranded in 'deleting' until lease expiry.
Test covers the pre-existing-row + missing-storage boot.

* refactor(channel): remove the dead pre-resolved MediaRefs ingress path

lark.InboundMessage.MediaRefs and the resolver's early-returns for
pre-populated refs were vestiges of the pre-detached synchronous design
— no producer fills them before the router anymore. Worse, the intent
ledger made the path actively misleading: refs arriving without ledger
rows would be silently skipped at bind (with a log blaming the
reconciler), contradicting the field's "already persisted" contract.

Delete the field, its channelMessageFromLark mapping, and both
early-returns; channel.InboundMessage.MediaRefs is now documented as
what it actually is — ResolveMedia's output channel, always empty on
ingress, attachable only through a claimed ledger intent.

* fix(channel): enforce workspace tenancy on every ledger query

The intent-ledger upsert's conflict branch guarded only on state, so a
cross-workspace storage_key collision could rewrite the row's
workspace/message/url ownership; release and delete keyed on
(storage_key, lease_token) alone. The derived key embeds the workspace
UUID so none of this is reachable today — but tenancy must be enforced
by the workspace column in every query, never derived from the key
string (MUL-3515 rule, restated in this PR's review).

The upsert now updates only within the same workspace (a cross-tenant
conflict updates nothing, returns no row, and the resolver skips the
upload — the fail-safe direction), and release/delete take
(workspace_id, storage_key, lease_token). Tests pin that a foreign
workspace can neither steal, release, nor delete a row.

* fix(migrations): build the ledger primary key via a concurrent index

storage_key TEXT PRIMARY KEY created its unique index implicitly at
CREATE TABLE, against the repo convention that every migration index —
including a new table's unique index — is built CONCURRENTLY in its
own single-statement migration (the exact three-step pattern
client_usage_daily shipped in 207-209). The table now declares
storage_key NOT NULL, 216 builds the unique index concurrently, and
217 attaches the primary key USING INDEX; the claim index moves to
218. ON CONFLICT (storage_key) still resolves against the constraint,
and the full down/up round-trip is verified.

* fix(channel): bound each reconciler object delete with its own timeout

DeleteObject ran on the worker-lifetime context and the SDK's default
HTTP client has no overall request timeout, so one black-holed
connection would wedge the sequential sweep loop — and with it every
later batch and the backlog gauge — forever; a single-replica
deployment has no other worker to reclaim the lease. Each delete now
gets a 30s timeout (well under the 2min lease), and a timed-out delete
takes the existing release/backoff path. Covered by a blocking-deleter
test with an injectable timeout.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(channel): anchor the media deadline to the DB clock and bound queue waits by it

Two deadline gaps from review:

- The persisted marker was an application-clock timestamp compared
  against SQL now() everywhere it is read, so a skewed app node could
  shrink the fallback window and hand the agent a placeholder before
  the resolver's local budget ended. The append transaction now anchors
  a relative budget (MediaPendingSeconds) with now() + make_interval,
  writer and readers sharing one clock; the local resolve budget stays
  monotonic app-side. A DB test pins that the remaining budget measured
  by the DB clock equals the requested one.

- enqueueMedia's waits (per-session order, global slot) only watched
  shutdown, so in a burst an already-expired job kept its goroutine and
  payload until it reached the front. Both waits now also watch the
  message's deadline; on expiry the job skips the resolver entirely and
  runs only the empty finalize (marker clear + promotion), which also
  unblocks the session's later messages. Covered by a queued-expiry
  test that finalizes while the only slot is deterministically held.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(channel): start the local media budget before the append transaction

The DB anchors the durable fallback at insert-time now(), but the
local monotonic budget started only after AppendMessage returned — so
the resolver outlived the fallback by the append/commit latency, a
window where the deferred task is already claimable while the resolver
still runs and the agent reads a placeholder that binds moments later.
Capture the local deadline before calling AppendMessage, restoring the
ordering local-gives-up <= durable-fallback-fires. A slow-append test
pins that the resolver's context deadline is measured from the
pre-append instant.

* fix(channel): heartbeat the reconciler lease per row

One claim covers up to 50 rows under a single 2-minute lease, but the
batch is processed sequentially and each delete may run its full 30s
timeout — a few stalled deletes could outlive the lease mid-batch,
letting another replica reclaim the tail: duplicate concurrent
deletes, inflated attempt/backoff on rows whose owner was alive, and
skewed metrics.

The lease is now renewed before EACH row's settle work, so it only
ever needs to cover one row's worst case (invariant-tested: lease >=
2x the per-delete timeout). A renewal that matches no row means
another worker reclaimed it after a genuine expiry — the row is
skipped, leaving the new owner's state untouched. Test simulates a
mid-batch reclaim and pins the skip.

* fix(channel): dedup post media resources and make local writes atomic

A rich post may reference the same image_key/file_key in several spans.
The object key derives from (message, type, key), so duplicates uploaded
to the SAME key twice: LocalStorage.UploadStream truncated the
destination up front and removed it outright on a copy error, so a
second failing attempt destroyed the object the first success had
produced — leaving an attachment row pointing at nothing. A second
succeeding attempt instead produced two attachment rows for one object.

Collapse duplicate spans by (fetch type, platform key) before the
upload loop, and write local uploads through a temp file renamed into
place so a failed write can only discard its own temp file. Tests cover
a duplicated span uploading once and a failed re-upload leaving the
previous object intact.

* fix(channel): fence late-materializing PUTs with a tombstone schedule

A DELETE cannot be ordered against a PUT the client already abandoned:
the store may materialize the object after the delete completes. The
reconciler cleared the ledger row right after deleting, so such an
object had no row and nothing to reclaim it — which made the settle
delay the de-facto correctness barrier for the PUT/DELETE race, exactly
what the design says it must not be.

The row is now kept as a tombstone ('tombstoned' state, migration 226's
CHECK) and re-deleted on a widening schedule (15m, 1h, 6h, 24h, the
pass index carried in last_error), so a late materialization is
reclaimed by a later pass; only after the schedule is exhausted is the
row dropped. Claim, heartbeat, lease, and tenancy predicates are
unchanged — a tombstone is claimed exactly like any other due row. A
separate gauge reports tombstones so they cannot be mistaken for a
backlog of objects awaiting reclaim, and the header comment now states
precisely what state fences (bind/commit) versus what the schedule
fences (late PUTs).

Tests: the reviewer's interleaving — DELETE completes, the abandoned PUT
materializes right after, and the object is gone by the end of the
schedule — plus a full schedule walk asserting the object is counted
once and the row clears at the end.

* fix(channel): tombstones must re-delete, not re-ask the reference question

A tombstone revisit ran the same reference check as a first settle, so
an attachment carrying the same URL — a re-ingested copy of the object —
sent the row down the "referenced, keep it" branch: the object was kept
and the row cleared, abandoning the re-delete schedule that fences the
ORIGINAL object against an abandoned PUT. A tombstone has already been
judged unreferenced and deleted; it exists only to re-delete whatever
materializes later, so it now goes straight to the delete + schedule
tail (extracted as settleDeletedObject, shared with the first settle).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(channel): keep the tombstone schedule position in its own column

The re-delete pass index was encoded into last_error, which the failure
path also writes: one failed re-delete erased the position and restarted
the walk. A store failing intermittently could therefore keep a tombstone
alive indefinitely — every recovery would resume at pass 1 and the row
would never reach the end of the schedule to be dropped.

tombstone_pass is now its own column (the table is introduced in this PR,
so migration 226 carries it), advanced only by a successful delete, and
the tombstone write clears the now-stale last_error. Test walks the
schedule across a failed re-delete and asserts it resumes rather than
restarts, and that the row still terminates.

* fix(lark): derive media object keys per chat message

The object key was derived from the platform message alone, so a second
ingest of the same Feishu message reused the first ingest's ledger row.
That row can be a tombstone (up to ~31h while the re-delete schedule
runs), and the intent upsert refuses anything that has left 'pending', so
the second ingest skipped the upload and silently produced a placeholder
with no attachment. A re-ingest is reachable: the inbound dedup claim is
reclaimable once 60s stale and the dedup row is only vacuumed after 24h.

Keying on the chat message the object will attach to keeps the two
ingests independent, and nothing leaks: each one's objects are covered by
its own ledger row.

* refactor(storage): route both local upload paths through one atomic write

UploadStream wrote through a temp file and renamed into place, but the
buffered Upload path still truncated the destination up front — the
destructive shape the stream path exists to avoid, one caller away from
coming back. Both now share writeAtomic, which also restores the 0644 the
direct write used (CreateTemp makes files 0600).

* chore(channel): gofmt the media-pending append fields

* fix(storage): keep the local upload chmod best-effort

The rename-into-place rewrite made a failed chmod fail the whole upload.
CreateTemp's 0600 has to be widened to the 0644 the direct write used, but
an upload dir on a mount that ignores chmod (SMB/NFS/FUSE) accepted the
old direct write fine — turning those deployments' uploads into hard
errors would be a regression for a cosmetic property. Log and continue.

Tests pin 0644 on both upload paths, and that a failed buffered upload
leaves no temp litter and no damage to a previous object.

* fix(channel): never re-delete an object an attachment references

The tombstone pass skipped the reference check and deleted unconditionally,
so a durable attachment carrying that URL lost the only object it can read
— the dangling attachment the intent ledger exists to prevent, and the
opposite of the posture every other path here takes ("a reclaimable orphan
beats a broken attachment").

The check now runs on every pass. A positive result on a tombstone is
unreachable by design — keys are per (chat message, resource) and a bind
cannot attach a key that has left 'pending' — so reaching it means an
invariant broke: keep the object, clear the row, log it, and count it on
a dedicated reconciler_tombstone_referenced_total counter. The test's
contract is flipped to assert the referenced object survives.

* fix(storage): make the local staging file reclaimable after a crash

os.CreateTemp's random suffix meant a crash between the staging write and
the rename left a file nothing could name: the ledger records only the
final storage key, and DeleteObject removed only the object and its
sidecar. Each leftover can approach the 100 MiB resource cap and they
accumulate without bound.

The staging path is now derived from the object key, so DeleteObject
removes it alongside the object — which makes the media reconciler reclaim
it too, since the intent row is written before the upload. Opening it 0644
directly also drops the chmod the previous commit had to make best-effort.
Both read paths refuse the staging name (keys come from the request URL,
and a half-written body should not be readable); a user-supplied ".tmp"
extension is unaffected, since object keys are generated and never
dot-prefixed.

* chore(channel): renumber the media migrations after merging main

main took 224 (agent_task_session_rollout_missing), so the ledger group
moves to 225-230 and the cross-references inside the table migration follow.
main's CompleteTask also grew a sessionRolloutMissing parameter; the three
call sites this PR added to chat_input_ownership_test.go pass false.

Verified the way the numbering is meant to be verified: full migration set
applied from scratch on the merged tree, and the whole server suite run
against that database.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(channel): let Postgres compute every reconciler deadline

The reconciler built settle cutoffs, lease expiry, backoff and re-delete
times from the process clock and compared them against the database's
now(). A replica whose clock had drifted would therefore settle rows whose
upload was still in flight (the object is deleted and the bind then refuses
to attach — media silently lost), hand out leases that are born expired
(rows churn between workers, attempt/backoff inflate), or compress the
tombstone schedule that fences a late-materializing PUT.

The four settle queries now take durations and derive their timestamps from
now(), so every replica reads one clock. The parameter types are the guard:
an app-side timestamp can no longer be passed. Test asserts the persisted
lease, backoff and re-delete deadlines all track the database's now().

The generated code also picks up main's new agent_task_queue column in the
two RETURNING task.* queries this PR adds.

* chore(lark): drop unrelated gofmt-only churn from this PR

Six files carried whitespace/comment-reformatting with no functional
change, unrelated to the inbound media pipeline. Reverting them to the
base revision keeps the diff focused on the feature (75 -> 69 files):

  server/internal/service/empty_claim_cache.go
  server/internal/integrations/lark/markdown_detect.go
  server/internal/integrations/lark/ws_chunk_assembler.go
  server/internal/integrations/lark/ws_chunk_assembler_test.go
  server/internal/integrations/lark/ws_frame_test.go
  server/internal/integrations/lark/registration_test.go

Verified: `git diff -w` against these files was already empty, so no
behavior is affected. go vet clean; tests covering these files pass.

4581e9ee76 fix(server): surface real reason for failed quick-create (MUL-5268) (#5898)
* fix(server): surface real reason for failed quick-create (MUL-5268, #5885)

When an agent's quick-create run finishes without producing an issue, the
completion path wrote a fixed "agent finished without creating an issue"
inbox, discarding the real reason — most often the active-duplicate guard
rejecting the create. Users saw no actionable detail.

notifyQuickCreateCompleted now:
- distinguishes pgx.ErrNoRows (a confirmed no-issue → real failure) from a
  genuine lookup fault (DB/timeout), so a transient error no longer mislabels
  a run that may actually have created the issue;
- on the real-failure branch, surfaces the agent's final output as the
  failure reason. The quick-create prompt already requires the agent to exit
  with the CLI error as its only output, so this carries the concrete cause
  (e.g. the existing issue's identifier + status), unescaped, bounded, and
  redacted. Empty output falls back to the existing generic message.

No API/CLI contract or migration change.

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

* fix(server): never end quick-create with no notification on lookup fault

Review follow-up. The previous commit returned silently when the completion
lookup failed with a non-ErrNoRows error, to avoid misreporting a failure that
was never observed. But the task is already completed and nothing retries this
reconciliation, so a single transient DB fault permanently stranded the
requester with no inbox result at all.

The indeterminate branch now writes a neutral, terminal notification: it does
not assert failure (the agent may have created the issue), does not reuse the
agent output as if it were the confirmed reason, and points at the one safe
next step — check recent issues before retrying, so a retry cannot silently
produce the duplicate the guard exists to prevent.

notifyQuickCreateFailed / notifyQuickCreateUnconfirmed are now thin wrappers
over a shared writer so both outcomes keep the identical row shape and the
frontend's 'Edit as advanced form' recovery affordance.

Tests:
- TestQuickCreateLookupFault_WritesUnconfirmedInbox: fails against the previous
  commit with 'no rows in result set' (the exact silent-drop), passes now. Uses
  a DBTX wrapper that faults only GetIssueByOrigin so the inbox write still
  reaches the real DB.
- TestQuickCreateFailure_RedactsAgentOutput: locks in that the newly-surfaced
  agent output is scrubbed before storage.

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

* fix(inbox): render unverified quick-create outcome as neutral, not failed

Review round 2. Three fixes.

1. Rebased onto main and updated the three CompleteTask call sites for the
   new sessionRolloutMissing parameter; the branch no longer compiles-fails
   on the merge ref.

2. The unverified outcome reused the quick_create_failed inbox type, so every
   client framed it as a failure regardless of the neutral title/body: web
   list rendered 'Failed: {detail}', web detail showed 'Create with agent
   failed', mobile rendered 'Failed: ...', and getInboxDisplayTitle replaced
   the neutral title with the original prompt. Users saw 'Failed: Couldn't
   confirm...' — asserting a failure never observed. Added a distinct
   quick_create_unconfirmed type end to end: core type union, web list label
   (no failure framing), web detail pane, the original-prompt box and 'Edit as
   advanced form' recovery affordance, mobile label + display title, and en /
   zh-Hans / ja / ko strings. Older clients hit their existing default branch
   and render the already-neutral title.

3. The terminal notification reused the caller's context, so a lookup that
   failed with context.Canceled / DeadlineExceeded failed the write for the
   same reason and still dropped the notification. The write is now detached
   via context.WithoutCancel with a bounded timeout.

Tests (each verified to fail without its fix):
- TestQuickCreateLookupCancelled_StillWritesUnconfirmedInbox: cancels the ctx
  at the lookup; without the detach, 'no rows in result set'.
- inbox-detail-label.test.tsx: resolves accessors against the real en locale;
  pointing the unconfirmed case back at failed_with_detail reproduces
  'Failed: Couldn't confirm...'.
- inbox-display.test.ts: both outcomes stay recoverable rows.

85a14cde37 fix(daemon): gate codex session pointer writes on rollout presence (MUL-5305) (#5960)
* fix(daemon): gate codex session pointer writes on rollout presence (MUL-5305)

Codex issue follow-ups on local_directory projects intermittently lost
their session: the server sent a prior session whose rollout was not in
the task CODEX_HOME, so the daemon dropped the resume and started a fresh
thread (gateCodexResumeToRolloutPresence), losing the conversation.

Root of the bad pointer: the daemon persists a Codex session id as the
resumable pointer at two points -- the mid-flight pin and the terminal
report -- before the rollout is guaranteed on disk. A task that exits
early (crash / runtime offline / timeout) leaves a pinned/reported
session id with no rollout; GetLastTaskSession (which accepts failed
rows) then hands it to the next follow-up, which drops it.

Enforce the invariant at write time: only record a Codex session as the
resumable pointer once its rollout is present in the per-issue store,
with a short bounded wait for flush. If it never lands, don't overwrite
the last good pointer -- a blanked session_id becomes NULL server-side,
so GetLastTaskSession falls back to the most recent session whose
rollout is real. Non-Codex providers are unaffected; crash recovery is
preserved because a present rollout still pins.

- codexSessionResumable: shared write-time presence check (bounded wait)
- runTask: gate the terminal session_id before reporting
- executeAndDrain: gate the mid-flight pin (thread codexHome through)
- tests: helper cases + behavioral pin test

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

* fix(daemon): address review — don't silently downgrade completed sessions (MUL-5305)

Follow-up to review feedback on #5960:

- Must-fix 1 (silent downgrade): limit the write-time session withholding
  to NON-completed terminal states. A missing rollout means no resumable
  conversation was persisted, so a withheld non-completed attempt loses
  nothing; a completed session is authoritative and, if its rollout is
  anomalously absent, is still recorded so the next run's resume gate
  discloses the loss (PriorSessionResumeUnavailable, MUL-4424) instead of
  silently falling back to an older session. Extracted
  resumableTerminalSessionID.
- Non-blocking risk: pin the mid-flight resume pointer with a per-status
  presence check instead of one fixed 2s window, and set sessionPinned
  only once the rollout is confirmed, so a rollout that lands shortly
  after the first status is still pinned this run.
- Must-fix 2 (regression coverage): pin skipped when rollout absent (no
  /session call); terminal helper (completed keeps / failed withholds);
  and a DB-backed GetLastTaskSession test proving the next claim falls
  back to the older recorded session when the latest was blanked.

* fix(daemon): disclose Codex session continuity gaps end-to-end (MUL-5305)

Addresses review feedback on #5960.

Must-fix 1 — a completed turn whose rollout is missing is exactly the
#5934 case (the reporter waits for each turn to finish), so it can no
longer be excluded from withholding. Withhold the session for ANY
terminal state, and pair the withhold with a persisted continuity-gap
signal so the next claim still discloses the loss even while resuming an
older good session:
  - new agent_task_queue.session_rollout_missing column (migration 224)
  - daemon sends session_rollout_missing on the terminal report; the
    handler clears the resume pointer (MarkTaskSessionRolloutMissing,
    overriding FailAgentTask's COALESCE) and flags the row
  - claim reads GetLatestTaskRolloutMissing and sets a new
    prior_session_resume_unavailable response field, which the daemon ORs
    into the brief's PriorSessionResumeUnavailable disclosure

Must-fix 2 — Codex reveals the session id on a single task_started
status, so a one-shot presence check missed a rollout that flushed later
and lost in-flight crash recovery. Pin via a background waiter bounded by
the run's context that pins the moment the rollout lands.

Tests: - completed + rollout missing -> next claim withholds the bad session
    AND flags the continuity gap (cross-layer DB test)
  - session pinned once its rollout appears after the status (mid-run)
  - pin skipped while the rollout is absent
Co-authored-by: multica-agent <github@multica.ai>

* fix(server): make continuity-gap write atomic + disclose on all claim paths (MUL-5305)

Addresses review round 3 of #5960.

Must-fix 1 — the previous handler-level marker ran AFTER the terminal
transaction committed, and FailTask creates + wakes the auto-retry inside
that same transaction, so a retry could claim the rollout-missing session
before the marker cleared it (and a marker failure was swallowed). Move
session_rollout_missing INTO the terminal write: CompleteAgentTask and
FailAgentTask now force session_id NULL (overriding Fail's COALESCE that
would keep a stale mid-flight pin) and set the flag in the SAME UPDATE, so
the withhold + gap flag commit atomically with the retry creation. The
flag is threaded through TaskService.CompleteTask/FailTask; the swallowed
best-effort MarkTaskSessionRolloutMissing query is removed.

Must-fix 2 — the daemon withholds for all Codex tasks, but only the issue
non-rerun claim consumed the disclosure. Now every fallback path sets
prior_session_resume_unavailable: the manual-rerun branch reads the source
task's session_rollout_missing, and the chat branch reads a new
GetLatestChatTaskRolloutMissing.

Tests (cross-layer DB):
- completed + rollout missing via the real CompleteAgentTask terminal
  write -> session withheld AND gap flagged
- failed + rollout missing forces session_id NULL over the COALESCE-
  preserved mid-flight pin in ONE statement

Deploy order: migration + server first, daemon second (new fields are
omitempty and ignored by an old peer).

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

* fix(handler): return 5xx on FailTask error + cover claim-response gap paths (MUL-5305)

Addresses review round 4 of #5960.

Must-fix 1 — the FailTask handler returned 400 on a service/DB error, but
the daemon's terminal callback treats 400 as permanent (postJSONWithRetry
/ isTransientError bails without retrying). Since the fail transaction is
now the sole persistence point for the withheld session + continuity-gap
flag + auto-retry, a rolled-back fail must be retried, so return 5xx (an
invalid request body still returns 400), mirroring CompleteTask.
Regression: client.FailTask retries on a transient 5xx and eventually
succeeds.

Must-fix 2 — add claim-response-level regressions that drive the two new
disclosure branches through buildClaimedTaskResponse:
  - chat: the latest terminal task on the session withheld -> the next
    chat claim sets prior_session_resume_unavailable
  - manual rerun: the source task withheld -> the rerun claim discloses
These handler DB tests run under CI's fully-migrated database (the local
workspace DB cannot set up the handler fixture).

3d4c5c7da2 feat(cli): add 'multica agent copy' to fork an agent across runtimes (MUL-5279) (#5961)
Add a CLI/headless equivalent of the web Duplicate action: copy an existing
agent's portable config into a new agent, optionally on a different runtime,
leaving the source untouched.

The command composes existing endpoints (GET source, then POST create) — no new
server API — passing the source's skill ids in skill_ids so bindings attach in
the same create transaction the server already runs, keeping the mutation atomic.

- Copied by default (each overridable): name (+" (copy)"), description,
  instructions, avatar, custom_args, max_concurrent_tasks, invocation permission,
  and assigned workspace skills.
- Runtime-specific fields (model/thinking_level/service_tier) copy only on the
  same runtime; a different --runtime-id drops them and requires --model.
- Secrets/machine-local (custom_env/mcp_config/runtime_config) are never copied;
  they are set only via explicit secret-safe flags.

Docs: updated the multica-creating-agents built-in skill + source map.

ecce589867 MUL-5265: GitHub API-snapshot PR cards — CI status + mergeability (#5889)
* feat(github): API-snapshot PR cards — CI status + mergeability (MUL-5265)

Fetch each linked PR's CI checks and mergeability from the GitHub GraphQL
API as the single source of truth (Plan C). Webhooks, page visits and a
bounded TTL sweep are refresh triggers only; nothing is inferred from
webhook payloads anymore.

Backend (server/internal/integrations/ghsnapshot):
- installation-token cache + GraphQL client (private key / tokens never logged)
- one paginated pullRequest query -> normalized per-check snapshot
- outbound queue: (installation,repo,PR) dedup + single in-flight per PR,
  bounded worker pool, Retry-After / rate-limit backoff, jitter
- head-SHA-guarded atomic batch replace (a slow response for an old head
  can never overwrite a newer head's snapshot)
- bounded chase window (30s->5m, stops on terminal/closed) + page-visit +
  TTL refresh; clean degradation when no App private key is configured

Removes the old suite-level webhook aggregation display path (query +
handlers + tests). check_suite / check_run / status are now pure triggers.

Frontend: PR card shows two independent tri-state elements (CI status +
mergeability). "Ready to merge" only when merge state is clean; no-checks
and unknown-mergeable never assert a positive verdict; progress strip
removed; four locales; stale marker.

Docs: github-integration + environment-variables (four languages) — now
required App private key, read-only Checks/Commit-statuses permissions,
new event subscriptions, capability boundaries and troubleshooting.

* fix(github): concurrent check-run index migration + singleflight token mint

Address Elon's third-round review on the MUL-5265 PR snapshot pipeline.

Must-fix — migration built a non-concurrent index. The
github_pull_request_check_run table declared PRIMARY KEY (pr_id, ordinal)
inside CREATE TABLE, which builds a unique index synchronously and violates
the repo rule that every migration-created index (including on a new table)
use CREATE UNIQUE INDEX CONCURRENTLY in its own single-statement file. Split:
222 now creates the table without a primary key; new 223 adds the
(pr_id, ordinal) unique index CONCURRENTLY. The atomic delete-all/insert
write path already guarantees ordinal uniqueness, so a plain unique index is
sufficient; the index also serves the pr_id-prefix list aggregation and the
workspace/PR cleanup deletes.

Nit — token mint now singleflights per installation. installationToken
released the lock before minting, so the N workers of one installation could
mint N tokens on a cold cache or a simultaneous renew. Concurrent callers for
the same installation are now collapsed via singleflight into one HTTP mint;
added a -race concurrent-mint test asserting a single mint under 16 callers.

Verified: fresh DB migrates through 223 (table has no PK, concurrent unique
index present); ghsnapshot suite + new test pass under -race; migration lint
and handler github/workspace-delete tests pass; sqlc produced no diff;
go build / vet / gofmt / git diff --check clean.

73b0015475 feat(vcs): make self-hosted Git providers self-host-only (MUL-3772, MUL-5138) (#5888)
* feat(vcs): gate self-hosted Git providers to self-host deployments only (MUL-3772)

The Forgejo/Gitea/GitLab integration is intended for self-hosted Multica, where
Multica can reach a Git instance on the operator's own network. On the managed
multi-tenant cloud it adds an SSRF surface (connect validates a user-supplied
instance URL from the server) and would store third-party Git tokens for all
tenants under one key, while only serving the small subset of users whose
instance is publicly reachable. Product decision: offer it on self-host only.

- Add an explicit deployment switch MULTICA_VCS_INTEGRATION_ENABLED (default
  off). Connect, rotate, and webhook now require BOTH the switch on AND a valid
  MULTICA_VCS_SECRET_KEY — the switch is the product boundary, not key presence
  alone. When off, connect/rotate return 404 and the webhook returns a bare 404
  (no config leak), independent of the frontend.
- /api/config exposes vcs_integration_available (mirrors the switch, omitted
  when false) so the Settings UI hides the whole "Git providers" section on
  cloud instead of surfacing an operator-only "missing key" hint.
- docker-compose.selfhost.yml defaults the switch on; .env.example documents it.
- Docs (en/zh) lead with a callout: available on self-hosted Multica only, not
  Multica Cloud, and clarify "self-hosted" means Multica itself, not just Git.

#5006 / #5883 stay in place — the schema and backend capability are retained;
this only gates availability. No cloud VCS connection can exist (connect always
required the key, which the cloud never set), so nothing needs migrating.

Verified: go build/vet + VCS/config handler tests on a fresh migrated DB
(incl. a new disabled-deployment 404 test); pnpm typecheck (core + views) and
the integrations-tab + core schema/config vitest suites pass.

168620fc15 MUL-5163 fix(agents): rebind the Agent Builder carrier when the runtime is switched (#5780)
Switching the runtime mid-conversation in Build with AI only updated local React state, so the picker could show runtime B while every subsequent message still executed on the runtime frozen at session create time.

- Add PATCH /api/agent-builder/sessions/{id}/runtime to rebind the hidden builder carrier (runtime_id/runtime_mode, model cleared since model ids are per-runtime). Creator-only, builder carriers only, target must be in-workspace, usable by the member, and online; a reply in flight returns 409.
- Serialise rebind against send: both take LockChatSessionForRuntimeBind on the chat_session row and SendDirectChatMessage re-reads the agent inside that transaction, so a send blocked behind a rebind cannot resume and stamp its task with the runtime the switch moved away from.
- Leave chat_session.runtime_id stale on purpose so the daemon starts a fresh provider session on the new runtime while Multica-side history and the draft survive.
- Frontend updates the draft only after the server reports the bound runtime, blocks sending during a rebind, disables the Mine/All filter alongside the trigger, and explains why the picker is locked during a pending reply.

Closes #5773

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

* fix(agents): renumber runtime-skill migration and broadcast agent:status on toggle

Address the MUL-5101 review blockers on PR #5686:

- Rebase onto main and renumber the runtime-skill-disable migration
  202 -> 203. main added 202_runtime_profile_add_qwen, so the pair
  collided on prefix 202 and migrations_lint_test would reject the
  duplicate. 203 is the next free prefix.
- Publish an "agent:status" event after persisting a
  disabled_runtime_skills override, mirroring the workspace-skill toggle
  in writeUpdatedAgentSkills. The realtime layer keys off this event to
  invalidate workspaceKeys.agents, so other open web/desktop/mobile
  clients now drop their stale toggle state instead of only the
  initiating tab refreshing. Reload junction-table skills before the
  broadcast so it doesn't signal cleared skills (#3459).
- Add a handler regression test proving the broadcast fires on both
  disable and enable.

* fix(issues): make table window filters, selection, and export authoritative

Round-2 review fixes for the issues table (MUL-4797):

- Send the agents-working filter as a server ids facet so matches on
  unfetched pages surface and total/pagination/export agree; a present-
  but-empty id list yields an empty window instead of an unfiltered one.
- Reset surface selection when the membership window changes and act on
  selection ∩ visible rows in the batch toolbar, so batch actions,
  Export selected, and the count all share one authoritative set.
- Materialize the full flat window while table grouping is active, and
  suspend hierarchy nesting / parent-based grouping until the window is
  complete so structure cannot reshuffle as pages arrive; suppress
  header facet-count badges while the table window is partial.
- Resolve actor directories and the property catalog at export time and
  fail the export instead of writing Unknown* actors or dropping
  configured property columns on cold/errored lookups.
- Append a unique id tie-break to the list/grouped ORDER BY and mirror
  it in compareIssuesForSort so offset pages are stable across
  same-timestamp ties.

* fix(issues): bound table structure window and align chip/transport/selection

Round-3 review fixes for the issues table (MUL-4797):

- Cap whole-window materialization at TABLE_STRUCTURE_MAX_WINDOW (1000):
  below it the remaining pages load automatically — hierarchy applies
  without scrolling to the last page — and above it grouping/hierarchy
  suspend with an explicit toolbar notice instead of triggering an
  unbounded workspace download from a persisted view option.
- Give the agents-working chip the authoritative in-window running set
  (the ids-facet window query, shared key with the filter-on state) so
  its badge can no longer say 0 while the filter would find matches on
  unfetched pages; falls back to loaded-row scoping elsewhere.
- Route ids-facet windows through a new POST /api/issues/query twin —
  hundreds of running-issue UUIDs overflow the ~8 KB GET request-line
  budget of common proxies. The body carries the same key/value pairs;
  the handler rebuilds the query string and delegates to ListIssues.
- Reset surface selection during render (key-change pattern) instead of
  a post-commit effect, so no frame ever pairs new membership with the
  old selection.

* fix(issues): harden table auto-pagination against errors and stale totals

Round-4 review fixes for the issues table (MUL-4797):

- Stop the structure materialization loop (and the scroll sentinel) when
  the window query is in error state — a persistently failing page left
  hasNextPage true and isFetchingNextPage false after every attempt, so
  the ungated effect refired forever. Resuming is an explicit toolbar
  Retry. The advancement decision now lives in a pure, tested
  shouldAutoLoadNextStructurePage helper.
- Make the structure ceiling a hard stop: the ceiling check reads the
  LATEST page's total (pagination already advances on it, so a stale
  small page-1 total could re-open unbounded materialization), and the
  loop additionally halts on loaded count >= ceiling regardless of any
  reported total.
- Drive the working (ids-facet) window to completion — it is inherently
  bounded by the running set — and treat it as the chip's authoritative
  scope only when complete, so >100 running issues no longer under-count
  as a single page.

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

* fix(issues): make working-window pagination capped and unknown-aware

Round-5 (final) review fixes for the issues table (MUL-4797):

- The working (ids-facet) window now advances through the same
  shouldAutoLoadNextWindowPage gates as the structure loop — it shares
  the main table's cache key while the agents-working filter is on, so
  an uncapped chip-driven loop re-opened the very ceiling the table just
  enforced. An over-ceiling window stops after page one.
- A cold-load failure of the flat window is an ERROR state, not an empty
  workspace: isEmpty only claims empty on a successful zero-result
  fetch, and the surface renders a dedicated failed-to-load state with a
  reachable Retry (the in-table Retry never mounted without data).
- The chip scope is now tri-state honest: a COMPLETE window (or an empty
  running set) yields a precise count, keepPreviousData carries the
  last-known-complete set across re-keys, and everything else — cold
  resolving, failed, over the ceiling — presents as an explicit unknown
  ('Agents working: —') instead of a number derived from whichever
  incomplete window happened to be loaded.

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

* fix(issues): single pagination owner and placeholder-honest chip scope

Round-6 review fixes for the issues table (MUL-4797):

- Exclude placeholder data from the working-window completeness gate:
  on a re-key (running set or facet change) keepPreviousData leaves the
  OLD key's rows visible, and pairing them with the new task snapshot
  published a precise-looking number for a scope nobody fetched. The
  scope now reads unknown until the new key resolves.
- Make the shared table query single-owner while the agents-working
  filter is on: the chip's background loop no longer answers the same
  render snapshot as TableView's structure loop, and every auto caller
  (structure loop, working loop, scroll sentinel, retry) now uses
  fetchNextPage({cancelRefetch: false}) so a concurrent responder
  no-ops instead of cancel/restarting a fetch whose HTTP request is not
  abortable — which had been duplicating every offset.

465546b83b feat(autopilots): redesign the autopilot schedule editor (#5457)
Replace the free-form trigger-config form with a structured schedule
editor built on an orthogonal cron model: separate frequency, time, and
day-of-week/day-of-month dimensions map to and from cron expressions via
a dedicated grammar and mapping layer, with validation and a
human-readable describe() summary. The grammar suite drives the editor
against a combinatorially generated corpus of 51,755 distinct cron
expressions - every token form of every field, crossed - each judged
against a reference robfig/cron v3 parser.

Add a server-side /autopilot/cron-preview endpoint (plus schema and
React Query hook) so the editor shows upcoming run times, and echo
wildcard-carrying cron lists correctly instead of collapsing them.

Supporting pieces: timezone-aware formatting helper, segmented-toggle
and debounced-value utilities, a reworked time-input, and refreshed
en/ja/ko/zh-Hans locale strings.

Self-hosted upgrades to v0.4.3 failed closed on migration 198's VALIDATE of the strict attribution constraint, because the legacy rows migration 190 exempted were only backfilled out-of-band on cloud. Registers a pre-198 preMigrationHook that idempotently mirrors originator_user_id into accountable_user_id in batches before VALIDATE, with FOR UPDATE + repeated predicate to avoid clobbering concurrently-written rows, so a stuck-at-197 instance auto-heals on migrate up with no manual SQL. Originator-NULL rows are left untouched. Verified with unit + concurrency + end-to-end tests against real Postgres.

1507997272 fix(agent): stop agents shipping local-path links, make Desktop 404 recoverable (MUL-4899) (#5557)
Agents were writing runtime-local paths into deliverables as clickable
links (`[screenshot](/Users/agent/work/shot.png)`). Two root causes, both
fixed here.

A. The brief never stated the delivery contract. Add an always-on delivery
invariant (outside writeOutput's kind switch, so no task kind can inherit
none) plus a per-surface file-delivery line for each of the five surfaces.
Chat splits into two: `attachment upload` works only on web/mobile chat,
never on an IM channel, so ChatChannelType is now threaded into
TaskContextForEnv.

The claim path only ever looked up Slack bindings, so a Feishu session
reported as a web chat and got upload guidance for a channel that cannot
carry attachments. Probe every channel type. The chat policy is two
independent layers and stays that way: delivery keys off "is there a
channel at all"; the `chat history` / `chat thread` commands stay
Slack-only because both endpoints are hardwired to h.SlackHistory and
there is no Feishu reader — ChatInThread only selects between those two
commands, so it stays Slack-only too.

Add a CLI hard-fail lint on `issue comment add` / `issue create` /
`issue update` as the enforcement backstop. Scoped narrowly, since a false
positive blocks a real deliverable: agent task context only (a human's PAT
run is untouched), real CommonMark link/image/autolink destinations only
via goldmark (a path in a code span or fence — how an agent quotes a path
it is discussing — is structurally invisible), and three high-confidence
signals only (`file://`, inside the workdir, or an existing local file).
A bare `/foo` is a valid origin-relative URI and is deliberately allowed.
`issue update` has no --attachment flag, so its hint redirects to
`comment add` rather than naming an argument it rejects.

B. Desktop presented the resulting router 404 as an unknown crash. 8 of 18
desktop_route_error reports were users clicking such a link and being told
the app broke and to file a bug. Split the 404 into a first-class Not Found
view: no crash framing, no Report error. Its recovery entry comes from the
tab store's active workspace, never from the failed pathname — deriving a
slug from `/Users/me/shot.png` yields "Users" and a button to `/Users/issues`,
a second 404.

Also add a will-navigate trusted-origin guard via the shared loadRenderer
(main + issue windows). This is origin hardening only, NOT the mechanism for
in-app links: client-side routing never fires will-navigate, so app paths
never reach it. Issue windows need no 404 work — their router only accepts
paths validated by parseIssueWindowPath and they do not listen for
multica:navigate, so a bad path cannot reach them.

Server-side completion observation is metric/log only and never blocks: it
is lexical (`file://` + task work_dir prefix) because the server cannot stat
the daemon's filesystem, and the metric label is a closed enum so no path or
reply text reaches Prometheus.

Verified: pnpm typecheck/lint/test (3582 tests), go vet, full Go suite
including new claim-path integration tests. cmd/multica was verified outside
the daemon workdir — inside one, 93 of its tests fail identically on
origin/main because the suite walks up and finds the runtime's own task marker.

7d04b1d9a3 fix(cli): fail fast with actionable daemon startup errors
* fix(cli): fail fast with login hint when starting daemon unauthenticated

'multica daemon start' (background mode) spawned the child first and
only then polled its health port. When the user never ran 'multica
login', the child died instantly on resolveAuth, but the parent kept
polling for the full 45s readiness window and ended with a vague
"check logs" warning and exit code 0 — looking like a silent hang.

Check the stored config token before spawning (mirroring
daemon.resolveAuth, which only accepts the config token) and exit
immediately with an actionable "run 'multica login'" hint.

'daemon restart' gets the same guard BEFORE its stop phase: it used
to stop the running daemon first and only then fail auth inside the
start phase, leaving the user with no daemon at all. The foreground
path already failed fast and is unchanged.

* fix(cli): report early daemon child exit with an actionable reason

Background 'daemon start' Release()d the child immediately and then
polled the health port blind. Any preflight failure — server
unreachable, stored token rejected with 401 — killed the child within
a second, but the parent still sat through the full 45s readiness
window and ended with a vague "check logs" warning and exit code 0.

Keep a Wait() goroutine on the child and select on it inside the
readiness poll. When the child dies before reporting ready, classify
what this startup attempt appended to the log and fail with exit
code 1 and a one-line reason plus next step:

  - token rejected / 401  -> run 'multica login' (profile-scoped)
  - connection refused / DNS / timeout -> server unreachable at <url>
  - anything else -> short log excerpt with DBG/INF noise dropped

* fix(cli): probe token validity and server reachability before restart stops the daemon

requireDaemonAuth only rejects an empty stored token, so a revoked or
expired token — or an unreachable server — passed the restart guard,
the running daemon was stopped, and the replacement child then died in
preflight, leaving no daemon at all (#5165).

daemon restart now runs a whoami round-trip (same /api/me call as
'multica auth status') against the server the daemon will talk to,
using the stored token, before entering the stop phase — and only when
a daemon is actually running, so plain 'daemon start' keeps its
zero-round-trip happy path. On 401 it reports the re-login hint; on a
transport error it reports the unreachable server; both state that the
running daemon was left untouched.

Regression tests cover a non-empty stored token against a fake 401
server and an unreachable server, asserting /shutdown is never
requested on the fake running daemon.

6b2097ccbb feat(inbox): archived notifications sub-view (MUL-3736) (#5518)
Adds an "Archived" sub-view to the Inbox, reachable from an entry at the
bottom of the main list, with per-row unarchive. Mirrors chat's archived
sub-view so the two surfaces share one mental model.

Backend:
- GET /api/inbox/archived and POST /api/inbox/{id}/unarchive. Kept off the
  existing GET /api/inbox so installed clients keep their contract and the
  unbounded archive never rides along with the main list.
- The archived query excludes any issue that still has an active row. Archiving
  is issue-level, so a new notification on an archived issue leaves old archived
  rows beside a fresh active one — without the guard the issue renders in BOTH
  lists. The exclusion lives in SQL so neither list depends on the other's cache.
- Unarchive is issue-level (mirroring archive) and leaves `read` untouched, so a
  restored unread item raises the unread badge again.
- v1 ships no pagination: LIMIT 200, newest-first, so truncation drops the
  oldest rows and never hides a group's newest one.
- inbox:unarchived event, fanned out to the recipient like the other personal
  inbox events.
- Two CONCURRENTLY-built indexes; inbox_item previously had none covering
  workspace/archived/created_at.

Frontend:
- Separate TanStack cache per list; every inbox event invalidates the workspace
  prefix, since any of them can move an item across the boundary.
- View persisted as ?view=archived, so refresh, back/forward, and the mobile
  detail-back all return to the list the user was in.
- Batch actions stay main-view only — they archive from the MAIN inbox, so
  offering them over the archived list would do the opposite of what it reads.
- Mobile subscribes to inbox:unarchived (its list gains the restored row); its
  own archived view remains follow-up.

Known debt: no pagination, so an archive past ~200 rows is truncated silently
in the UI; the entry's count is the deduplicated count of the rows returned.

Verified: pnpm typecheck/test/lint (0 errors), go build/vet, Go inbox suite
against a real Postgres, migrations up+down, and EXPLAIN confirming both new
indexes serve the query.

* feat(server): custom issue properties — definitions, typed values, CLI (MUL-4463)

Workspace-level property definitions (issue_property table; 7 types:
text/number/select/multi_select/date/checkbox/url) plus a typed value bag
on each issue (issue.properties JSONB keyed by definition UUID, mirroring
the metadata machinery: single-key atomic writes, 16KB cap, GIN index).

- Definitions: owner/admin only; agent actors rejected (agents propose,
  humans confirm). 20 active per workspace, 50 options per select,
  reserved built-in names blocked, archive instead of delete.
- Values: any member or agent; per-type validation with self-correcting
  error messages that enumerate legal option ids.
- API: /api/properties CRUD + PUT/DELETE /api/issues/{id}/properties/{propertyId};
  issue responses always emit the properties bag.
- CLI: multica property list/get/create/update/archive/unarchive and
  multica issue property list/set/unset with name→id translation.
- Events: property:created/updated, issue_properties:changed.

  (list with type badges/option chips/usage counts, create/edit dialog
  with option editor, archive/restore, 20-cap indicator). Admin-gated;
  members see a read-only catalog.
- Issue detail sidebar: custom properties join the built-in optional
  props' progressive disclosure — set values render as rows with
  type-appropriate editors (select/multi-select pickers, calendar,
  yes/no, inline input for text/number/url), unset ones live in the
  same '+ Add property' menu behind a separator. Archived definitions
  render read-only until cleared.
- Core: property types, zod schemas (lenient type strings for forward
  compat), api client methods, React Query hooks with optimistic

* fix(properties): address MUL-4463 review round 1 — mobile CI, option guard, mutation safety, schema tolerance

- mobile: EMPTY_ISSUE_FALLBACK gains the required properties field (mobile
  typecheck was the red CI check).
- server: PATCH /api/properties/{id} rejects config updates that remove
  select options still referenced by issues (409 with a per-option usage
  census via jsonb ?); renames keep ids and pass. Integration test included.
- core: property value mutations are serialized per workspace via mutation
  scope, snapshot the bag from detail OR list caches (board surfaces have no
  detail cache — the old path overwrote whole bags with one key), roll back
  to the snapshot or invalidate on error, and the last settled mutation does
  an authoritative detail+catalog invalidate (usage counts reconcile).
- schemas: unknown-shaped property values (future server types) are dropped
  per-entry in a preprocess step instead of failing the whole IssueSchema
  and blanking lists through parseWithFallback; test updated to lock the
  tolerant behavior.
- realtime: reconnect invalidation covers the property catalog; every
  issue_properties:changed event also refreshes catalog usage counts.
- ui: number editor accepts decimals (step=any); settings usage count
  pluralizes (issue/issues) with CJK-safe plural keys.

* fix(migrations): renumber issue properties to 179 and build the GIN index concurrently

main's migration sequence advanced twice under this PR (167 collision, then
an upstream renumber wave that claimed 178), so issue properties now sits at
179 — verified against main's current tip by the prefix-uniqueness lint.

The properties GIN index moves to its own single-statement migration (180)
using CREATE INDEX CONCURRENTLY — a plain CREATE INDEX on the hot issue
table would block writes for the duration of the build. Mirrors the
119_user_created_at_index pattern; full-chain dry-run on a fresh database
passes through 180.

* feat(web): custom-property list surfaces — filter, cards, sort, board grouping (MUL-4463 M2)

Brings custom properties to the issue list surfaces on top of the M1
definitions/values core:

- Filter: per-definition sections in the Filter dropdown (select /
  multi_select options with color dots and counts; checkbox as Yes/No
  pseudo-options). OR within a definition, AND across definitions;
  client-side in applyIssueFilters, mirrored into filterAssigneeGroups
  for the assignee-grouped board. Included in active-filter count and
  Clear all.
- Cards: per-property Display toggles (cardPropertyIds) render value
  chips on board cards and list rows via CustomPropertyValueDisplay.
- Sort: SortField gains property:<id> for number/date definitions.
  Server keeps position order (fixed sort enum); the surface controller
  re-sorts client-side, swimlane/gantt reuse the same comparator.
  Date-only strings compare lexically; missing values sort last.
- Board grouping: IssueGrouping gains property:<id> for select
  definitions — one column per option (definition order) plus a
  trailing No-value column, option-colored headings. Drag-drop moves
  position via UpdateIssue and applies the value through
  useSetIssueProperty/useUnsetIssueProperty (properties are not part
  of UpdateIssueRequest). Stale persisted property groupings fall back
  to status columns.

View-store: propertyFilters + cardPropertyIds persisted via the
partialize allowlist; clearFilters resets property filters; new fields
deep-merge cleanly into pre-existing persisted snapshots.

* fix(properties): address MUL-4463 review round 2 — desc sort, option bucketing, archived-state reconciliation

- sort: direction now applies to value comparison only; issues without a
  value sort last in BOTH directions (the whole-array reverse flipped them
  to the front on desc). Test covers the desc+missing case.
- board: values referencing an option removed from the definition bucket
  into the No-value column instead of vanishing (unmatched column ids
  dropped the issue entirely). Defense-in-depth behind the new server-side
  in-use guard; drag-utils test locks both behaviors.
- controller: persisted propertyFilters keyed by archived/deleted
  definitions are stripped before reaching the filter predicates, and a
  persisted property sort on a non-active definition degrades to manual
  order — previously both kept silently applying while the header claimed
  otherwise. The filter badge counts only active-definition filters.

* feat(properties): server-side property filtering and sorting on list endpoints

Property filter/sort now execute in the database, so results are correct
across the full issue set — not just the loaded 50-per-status window
(closes MUL-4493 item 1's filter/sort half; requested on MUL-4463).

- New `properties` query param on ListIssues and ListGroupedIssues:
  JSON {definitionId: [values]} compiled to an AND-of-ORs containment
  check (double NOT EXISTS over jsonb_array_elements). One value expands
  to every storage shape it could match — string (select), array element
  (multi_select), boolean (checkbox) — so the handler stays type-agnostic.
  Guarded at 20 definitions / 50 values.
- `sort=property:<definitionId>` resolves the definition and orders by a
  typed expression (numeric CASE cast for number, NULLIF text for
  date/text/url); missing values sort last in both directions. Malformed
  ids 400; unknown/archived definitions degrade to position order instead
  of breaking stale clients.
- Frontend: the property filter and property sort ride the IssueSortParam
  window bag, so every surface (workspace + my-issues variants), query
  key, and per-status load-more page carries them automatically. The
  client-side re-sort layer is gone; applyIssueFilters keeps its property
  predicate as an optimistic-update backstop.
- Regression test seeds 55 issues and proves a match at position 55 is
  returned by a filtered 50-row page, plus sort order/missing-last,
  AND-across-definitions, and the 400/fallback sort paths.

* fix(properties): address review round 3 — cache reconcile, merged-scope order, GIN-indexable filter, pool loader

- Cache reconciliation: property value writes (mutation settle + WS event)
  now invalidate every issue window whose server-side shape depends on
  property values — queries filtered by `properties` or sorted by
  `property:<id>` (detected via query-key predicate), covering flat lists,
  assignee groups, and my-issues variants. Windows without property params
  keep the cheap in-place patch. Fixes stale ordering/membership/counts
  under staleTime:Infinity.
- My Issues "All" scope: merged assigned/created/involves results are
  re-sorted with a comparator mirroring the server ORDER BY semantics
  (including property sorts and missing-last, created_at DESC tiebreak) in
  both the flat and assignee-grouped merge paths — relation concatenation
  no longer overrides the user's sort.
- Filter predicate rebuilt as plain bind-parameter containment ORs
  (AND across definitions): EXPLAIN now shows BitmapOr over
  idx_issue_properties_gin (the correlated jsonb_array_elements form
  defeated the index). Alternatives capped at 256 bind params.
- Property-grouped board gains a pool loader strip: one sentinel per
  status that still has server rows, keeping every issue reachable until
  per-column pagination lands (MUL-4493).
- Windowing regression test hardened: explicit positions + an assertion
  that the unfiltered first page excludes the target (the old fixture tied
  at position 0 and the created_at DESC tiebreak put the target on page
  one, proving nothing).
- Rollback safety: /api/properties 404 (old server) degrades to an empty
  catalog instead of a query error, which also keeps property params from
  ever being sent to pre-property servers; migration 179's CHECK
  constraints switch to NOT VALID + VALIDATE so the exclusive lock is
  instantaneous.

* fix(properties): harden concurrency and cache coordination from clean-room review

Backend (MUL-4762 F1/F4/F5):
- withPropertyLock: pg_advisory_xact_lock helper; definition create/update
  and value writes now serialize config-vs-value and cap-vs-insert races
  (workspace-level 'props:' lock + per-definition 'prop:' lock, ordered).
- propertySortExpr degrades archived definitions to position sort.

Frontend (F2/F3/F6):
- onIssuePropertiesChanged invalidates plain assignee-group caches too.
- Property value mutations cancel list refetches in onMutate and roll back
  only the touched key against the current bag (concurrent WS writes to
  other keys survive a failed write).
- useUpdateIssue reconcile drops the stale properties bag from the server
  snapshot; the property pipeline owns that field.
- Surface controller passes persisted property filters/sorts through
  until the catalog query settles (cold cache no longer strips them).

* fix(properties): open_only branch honors the properties filter

ListOpenIssues takes the parsed AND-of-ORs containment groups as a single
jsonb properties_filter param and unrolls them with a static double
NOT EXISTS; previously the open_only path parsed the properties param and
silently dropped it (clean-room review F7a).

* fix(properties): toast on failed board drag to a property column

Property-column drags rolled the card back silently on failure; mirror
the status/assignee drag path (use-issue-surface-actions) so the
snap-back is explained (clean-room review F3, drag half).

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.

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

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

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

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

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

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

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

* 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).

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

* 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 <github@multica.ai>

* 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.

* 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 <github@multica.ai>

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

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

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

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

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

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

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

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

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

Renumbered attribution migrations to 166-172 after merging main.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* 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.

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

* 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.

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

* 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.

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

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

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

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

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

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

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

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

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

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

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

* 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.

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

7985699df9 feat(help): surface the running server version in the Help popover (#4959)
Surface the running server build version in the Help popover so self-hosted
operators can confirm what's deployed and include it in bug reports.

- Backend exposes it via /api/config's server_version (from main.version),
  omitempty so older/unstamped builds omit the field.
- Unstamped "dev" builds are normalized to empty and the row stays hidden.
- The row is suppressed on the managed cloud (frontend host multica.ai) and
  shown only on self-hosted deployments.
- Frontend renders a muted footer row in the Help popover only when the value
  is non-empty; i18n added for en/ja/ko/zh-Hans.

c3dd9ec845 Machine-level batch task claim endpoint (MUL-4257) (#5193)
* feat(daemon-claim): machine-level batch task claim endpoint (MUL-4257)

Collapse the per-runtime /tasks/claim poll fan-out into a single machine-level
batch claim to cut /api/daemon claim request volume.

Server:
- agent.sql: = ANY(runtime_ids) batch variants of the claim queries
  (ListQueuedClaimCandidatesByRuntimes, PromoteDueDeferredTasksForRuntimes,
  ReclaimStaleDispatchedTasksForRuntimes); runtime.sql: GetAgentRuntimes(= ANY)
  so a whole machine's runtimes are resolved/promoted/reclaimed/listed in a
  constant number of queries instead of N.
- service.ClaimTasksForRuntimes: claim up to max_tasks across a runtime set,
  preserving per-(issue,agent) serialization, the concurrency cap, the
  empty-claim cache short-circuit, and every dispatch side effect. Batch
  promote replays the per-row side effects (task:queued + empty-cache Bump).
- handler.ClaimTasksByRuntime (canonical POST /api/daemon/tasks/claim, with a
  transitional /claim alias): validates daemon_id (required; must match the
  mdt_ token) and rejects runtimes bound to a different daemon (group-ownership
  check mirroring the WS path); resolves+authorizes each runtime_id; claims;
  and finalizes each task through the SAME FinalizeTaskClaim as the per-runtime
  endpoint (atomic token + delivered_comment_ids receipt), requeueing the exact
  claim and omitting it on failure. buildClaimedTaskResponse is extracted from
  the per-runtime handler and returns the delivered-comment ids plus a
  structured *claimBuildFailure so both paths share identical payload building
  and failure semantics (workspace-isolation, chat-input load/empty).
- max_tasks: negative -> 400, zero -> empty (never coerce to 1), positive
  capped at 32. runtime_ids parsed with non-panicking util.ParseUUID.

Daemon:
- Client.ClaimTasks posts daemon_id + runtime set + free-slot count to the
  canonical path under a short request-scoped timeout, bounding the
  head-of-line coupling the per-runtime pollers avoid (MUL-1744).

Tests: service batch drain / max_tasks cap / deferred-promote receipt /
finalize-failure rollback+requeue; handler routing + token, cross-workspace
skip, cross-daemon skip, daemon_id required, owner-missing cancel,
max_tasks=0/negative, invalid-uuid skip, comment delivery receipt, stale-reclaim
replacement receipt; client posts/parses (daemon_id + canonical path).

Follow-up: cut the daemon pollLoop over to a single batched poller (flips the
MUL-1744 isolation contract; needs its concurrency tests redesigned).

* feat(daemon-ws): generic WS request/response transport for daemon RPC (MUL-4257)

Add a generic daemon->server request/response layer over the existing WS
control connection, the transport for WS-first claim (HTTP fallback):
- protocol: daemon:rpc_request / daemon:rpc_response envelopes with a
  correlation request_id + method + body, and an rpc-v1 capability gate.
- daemonws.Hub: SetRPCHandler + goroutine-dispatched handleRPCFrame (bounded
  by a per-connection in-flight cap) that echoes the request_id; missing
  handler / saturation return non-2xx so the daemon falls back to HTTP.
  Read limit raised to 64KB for rpc requests carrying a runtime set.
- hub tests: round-trip, handler-error->non-2xx, no-handler->503.

* feat(daemon-ws): WS-first task claim over the generic RPC transport (MUL-4257)

Bind claim to the WS request/response layer, with HTTP fallback:
- server: handler.DaemonRPCHandler adapts a daemon:rpc_request (method
  tasks.claim) to the existing HTTP ClaimTasksByRuntime via a synthetic
  in-process request carrying the WS connection's identity (daemon_id +
  workspace + capabilities), so all auth / payload-building / finalization is
  reused unchanged. Wired via daemonHub.SetRPCHandler. ClientIdentity now
  captures X-Client-Capabilities so capability gating matches the HTTP path.
- daemon: wsRPCClient correlates responses by request_id over the shared WS
  connection; attached to the live connection's write channel (guarded so a
  Call racing teardown never sends on a closed channel) and detached on
  disconnect. rpc_response frames are routed in the read loop.
  Daemon.ClaimTasksWSFirst issues tasks.claim over WS and falls back to the
  HTTP claim endpoint on any transport failure (no conn / buffer full /
  timeout) — wired into the poller at the poller cutover.
- tests: handler tasks.claim RPC end-to-end (claims + dispatches) + unknown
  method 404; daemon wsRPCClient round-trip / timeout / unavailable /
  server-error / detach-fails-pending (all under -race).

* feat(daemon): cut claim poller over to machine-level ClaimTasksWSFirst (MUL-4257)

Replace the per-runtime HTTP poll loop with a single batch poller: each cycle
acquires all free execution slots (slot-before-claim) and issues ONE
ClaimTasksWSFirst across every runtime the daemon hosts (WS-first, HTTP
fallback), dispatching each returned task to its runtime. Wakeups (targeted /
catch-up / runtime-set change) collapse to one nudge. Removes runRuntimePoller
+ runtimePollOffset. The WS handshake now advertises the same capabilities as
HTTP (+ rpc-v1) so WS-built claim payloads keep skill-ref / coalesced-comment
gating.

Trades per-runtime isolation (MUL-1744) for one request, bounded by the short
per-request WS timeout / client timeout. Tests: batch poller claims across
runtimes + skips-at-capacity + pollLoop shutdown drain (replacing the
per-runtime poller tests); heartbeat isolation + runtime-set watcher kept.

* fix(daemon-ws): WS RPC disconnect-race panic + batch stale-comment-plan repair (MUL-4257)

Two PR #5193 review blockers:

1) WS RPC send-on-closed-channel race, both ends:
   - server: give each connection a cancelable ctx (cancelled on readPump
     teardown) and run the RPC handler under it, so a slow claim stops on
     disconnect; guard c.send with sendMu/sendClosed (trySend) so a late RPC
     response goroutine never writes to the closed channel. Heartbeat ack routed
     through the same guard.
   - daemon: wsRPCClient.deliver now sends under the mutex, serialized with
     attach(nil)'s close+delete, so a delivered response can't hit a channel
     the detach path just closed.
   - regressions (-race): daemon deliver-vs-detach; server
     disconnect-during-handler-response.

2) batch claim now runs the stale-comment-plan repair: extracted the
   per-runtime handler's repair (trigger deleted, only coalesced survive ->
   cancel + replay survivors) into shared repairStaleCommentPlanIfNeeded, called
   by both claim paths. Prevents the batch path (now the default poller) from
   finalizing+dispatching a task with no comment input and silently dropping the
   surviving user comment. Regression: batch omits the stale task, cancels it,
   and rebuilds the survivor into a new trigger plan.

* fix(daemon-ws): server-side RPC deadline + legacy claim fallback (MUL-4257)

Two review blockers:

1) WS RPC timeout/fallback (GPT-Boy): the daemon's WS wait didn't cancel
   server-side claim, so a slow WS claim could commit after the daemon fell
   back to HTTP, leaking dispatched tasks and breaking the free-slot bound.
   Fix: RPC envelope carries TimeoutMs; the server bounds the handler ctx by it
   (so ClaimTasksByRuntime's tx is cancelled/rolled back at the deadline), and
   the daemon waits budget + grace so a claim that committed before the deadline
   still reports back. A committed-then-unreported claim degrades to the same
   stale-reclaim safety net as HTTP, never a double effective claim. Regression:
   server-side TimeoutMs cancels the handler.

2) Backward compat (Terra-Boy): a new daemon against a server without the batch
   route (/api/daemon/tasks/claim 404) couldn't claim. Fix: ClaimTasksWSFirst
   falls back to the legacy per-runtime ClaimTask loop on a batch 404 and caches
   'batch unsupported' (reset on WS reconnect to re-probe after a server
   upgrade). Regression: server exposing only the legacy route.

* fix(daemon-ws): no double-claim on WS teardown/detach (MUL-4257)

Sol-Boy review blocker: on reconnect, teardown failed the pending RPC (→ HTTP
fallback) but then flushed the queued tasks.claim frame to the still-alive
socket, so the server committed the WS claim on top of the HTTP one — double
claim, WS batch orphaned to stale reclaim, breaking the free-slot bound.

- Teardown now closes the connection FIRST, so runWSWriter discards the queued
  RPC frame (write error path) instead of delivering it.
- A detach while a claim's frame is already in flight now returns a distinct
  errWSRPCUncertain; ClaimTasksWSFirst does NOT HTTP-fall-back on uncertain (the
  WS claim may have committed) — it skips the cycle and lets reclaim / the next
  poll recover. Genuine 'not sent' / timeout still fall back (safe: the
  server-side deadline guarantees no uncommitted claim by budget+grace).
- Regression: detach during an in-flight WS claim asserts zero HTTP claims
  (at most one path claims); plus the existing detach/deliver-race and
  server-timeout tests.

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

* fix(daemon-ws): cancelable RPC frames close the backpressure double-claim (MUL-4257)

Sol-Boy review blocker: the client's response budget starts at enqueue, but
the socket write is async (10s write deadline). A backpressured writer could
hold a tasks.claim in the local queue past the client timeout — the daemon
HTTP-fell-back, then the writer woke and delivered the stale WS frame, so the
server committed it too: same free slots claimed twice. No detach occurs, so
the prior errWSRPCUncertain fix did not cover it.

- WS frames are now cancelable (wsOutbound{sent,canceled} under a mutex). The
  writer calls beginWrite() before WriteMessage and skips cancelled frames.
- On give-up (timeout / detach / ctx), Call cancels the queued frame: if it was
  still pending the cancel wins and the frame is guaranteed never delivered
  (errWSRPCUnavailable → safe HTTP fallback); if the writer already began
  sending it the cancel loses and the outcome is errWSRPCUncertain (no
  fallback). The decision is atomic, so at most one transport claims.

Tests: wsOutbound cancel-before-write vs write-before-cancel; Call timeout
cancels an unsent frame (writer then drops it) vs uncertain when already sent;
plus the updated detach and existing timeout/race tests.

* fix(batch-claim): return partial success instead of dropping committed claims (MUL-4257)

Sol-Boy review blocker: ClaimTasksForRuntimes reclaims (step 2) and claims per
agent (step 6) in independent transactions, but a step-4 candidate-SELECT error
or a mid-loop ClaimTask error did 'return nil, err' — discarding tasks already
committed as dispatched. The handler 500s; the daemon sees a definite (non-
uncertain) 500 and HTTP-falls-back, claiming a SECOND batch into the same free
slots while the first batch waits for stale reclaim — the double-claim this PR
removes.

- Both error paths now prefer partial success: if any task has already
  committed (claimed non-empty), return it (nil error) so the handler finalizes
  and returns 200; the errored candidates stay queued for the next poll. The
  remaining error is logged. Only a genuinely empty result still returns the
  error (safe: no committed claim to lose, HTTP fallback just re-fails).

Regression (internal/service, DB-backed, fault-injected):
- PartialSuccessOnSecondAgentClaimFailure: fail the 2nd ClaimTask's Begin →
  the first agent's committed task is returned, not dropped.
- PartialSuccessOnCandidateQueryFailureAfterReclaim: a stale dispatched task is
  reclaimed, then the candidate SELECT fails → the reclaimed task is returned.

The single 500ms handshake bound was shared by the successful preamble

bf288349f6 feat(project): add start_date and due_date fields (MUL-4388) (#5313)
Projects become schedulable planning objects alongside their issues: add
optional start_date / due_date, mirroring issue.start_date / issue.due_date.
This is only the first slice of #5227 — labels, metadata, and the editable
metadata UI are still out of scope.

- migration 166: two nullable DATE columns on `project` (calendar days, no
  FK/index — matches the issue end-state after migration 112)
- sqlc CreateProject / UpdateProject carry the dates; UpdateProject uses
  narg so an explicit null clears
- handler: parse YYYY-MM-DD (400 on bad format), rawFields-presence clear on
  update, and the hand-scanned SearchProjects query returns the columns
- CLI: `project create/update --start-date/--due-date` (empty clears on update)
- frontend + mobile types/zod schemas: the two new schema fields are
  nullable().default(null) so a project from an older backend (frontend
  deploys before backend) parses to null instead of degrading the batch to
  the empty fallback; added a search schema drift test
- projects skill / CLI docs

a19e60a9e6 feat(chat): support images/files in agent chat replies (MUL-4287) (#5164)
* feat(chat): support images/files in agent chat replies (MUL-4287)

Agents can now attach images/files to their chat replies, matching how
comment attachments already work. The write-side gap was that the assistant
chat_message is synthesized server-side from the completion callback's text
output and never bound any attachments.

Backend:
- migration 150: nullable attachment.task_id (+ partial index), the transient
  handle that ties an agent's in-run upload to the reply it produces.
- POST /api/upload-file accepts task_id: gated to the task's own agent, in
  this workspace, on a chat task; tags the row with task_id + chat_session_id.
- CompleteTask (chat branch) binds the task's still-unclaimed attachments to
  the assistant message via BindChatAttachmentsToMessage (rejects rows already
  owned by an issue/comment/chat_message). An empty-output reply that produced
  files still creates a message so the images have an owner. FailTask binds
  nothing.

CLI:
- `multica attachment upload <path>` uploads a file for the current chat task
  (task from MULTICA_TASK_ID or --task) and prints id / markdown_url / a
  ready-to-paste markdown snippet.

Prompt:
- web/mobile chat prompt tells the agent how to attach a file to its reply.

Mobile:
- chat:done handler now always invalidates the messages list so attachments
  (absent from the event payload) refetch; mirrors web's self-heal.
- chat bubbles render standalone attachment cards via the existing
  CommentAttachmentList (dedup vs inline references), matching web.

Web/desktop needed no change — they already render message.attachments inline
and via AttachmentList, and self-heal on chat:done.

Tests: upload permission/isolation, bind-on-complete, empty-output+attachments,
FailTask no-bind, null task_id untouched, already-owned not stolen, CLI output
contract, mobile refetch-on-done.

* fix(chat): address review blockers on chat reply attachments (MUL-4287)

Two final-review blockers on PR #5164:

1. Mobile inline dedup only checked raw `url`, so an attachment referenced
   inline via `markdown_url` (exactly what the CLI snippet emits) rendered
   twice — once inline, once as a standalone card. Reuse the core
   `contentReferencesAttachment` helper so dedup covers every real reference
   form (stable /api/attachments/<id>/download path, url, download_url,
   markdown_url), matching web's AttachmentList. Extracted the filter into a
   pure `lib/attachment-dedup.ts` so it is unit-testable, and added a
   regression test covering `content` containing `attachment.markdown_url`
   (plus the other URL forms and same-identity sibling dedup).

2. CLI `attachment upload` emitted `![...]` image markdown for every file,
   producing a broken-image snippet for non-images. Emit image markdown only
   for image/* content types and a plain link otherwise, with a CLI contract
   test for both.

Approved scope otherwise unchanged.

* fix(chat): renumber attachment_task_id migration 150 -> 157 after main merge (MUL-4287)

Merged latest main; main renumbered its migrations and now occupies 150-156,
so 150_attachment_task_id collided with 150_agent_task_coalesced_comments and
would fail TestMigrationNumericPrefixesStayUniqueAfterLegacySet. Renamed to the
next unique prefix (157). No content change; migrate up applies cleanly.

* fix(chat): render agent-produced files as attachment cards, not raw links

The chat upload command handed the agent a bare `[name](url)` markdown
snippet. Pasted mid-sentence it renders as a plain text link (not a card),
and the referenced URL hides the auto-bound standalone attachment — so a
file the agent produced could end up showing as nothing.

Return the block-level `!file[name](url)` card syntax instead (images keep
`![name](url)` inline), and markdown-escape the filename so names with `[`/`]`
don't truncate the label. The prompt and CLI help now state the file
auto-attaches below the reply and the snippet is optional, only for placement.

* fix(chat): pin attachment upload to the token's task; build index concurrently

Two code-review findings on the chat-attachment path (MUL-4287):

- Isolation/privacy: POST /api/upload-file only checked the form task_id
  belonged to the caller's agent, not that it matched the task-scoped token's
  authoritative X-Task-ID. A run authorized for task A could tag an attachment
  onto task B (another chat task of the same agent, possibly another user's
  session), binding it into that reply on completion. Require the form task_id
  to equal the server-set X-Task-ID; add a same-agent/other-task 403 regression.

- Migration: split the task_id lookup index into its own migration (159) built
  with CREATE INDEX CONCURRENTLY (repo convention) — it cannot share a
  multi-command file with the ADD COLUMN in 158.

* fix(chat): enforce task-token source on attachment upload; drop transient task_id FK (MUL-4287)

Addresses the two remaining Preflight BLOCKERs on PR #5164.

Security (file.go): the task_id upload path compared the form task_id to
X-Task-ID but did not require X-Actor-Source=task_token. A normal JWT/mul_ PAT
leaves that header empty and the middleware does NOT strip a client-forged
X-Task-ID; resolveActor's fallback accepts a valid X-Agent-ID+X-Task-ID pair.
So a member who learned a task ID could forge both and inject an attachment
onto another chat task's assistant reply (cross-session/privacy leak). Now the
branch requires X-Actor-Source=task_token first (mirrors chat_history.go's
load-bearing boundary), then pins to the middleware-injected X-Task-ID. Tests
now go through the real task-token headers and add a forged-JWT-403 regression.

Migration (158): task_id is a transient binding handle (written once at upload
against an already-validated task, read only during that task's own
completion; durable owner is chat_message_id). There is no app-layer path that
hard-deletes agent_task_queue rows, and orphan uploads are already reaped by
attachment.chat_session_id's ON DELETE CASCADE — so an FK here would only add a
cascade dependency the app never relies on plus write overhead on the hot
attachment table. Drop the FK; task_id is now a plain UUID column. Added a
regression test that an unbound task-tagged upload is reaped on chat_session
delete. Index (159, CONCURRENTLY) unchanged.

* fix(mobile): align !file card preprocess with web parser + CLI escaped labels (MUL-4287)

Howard final-review blocker: mobile's `!file[...]` preprocess didn't keep up
with the CLI's file-card output, so agent-produced non-image files rendered
nowhere on mobile.

- `FILE_LINE_RE` used `[^\]]+` for the label, so the CLI's escaped-bracket
  output `!file[a\]b.pdf](url)` (cmd_attachment.go escapeMarkdownLabel) never
  matched — the line stayed literal AND `standaloneAttachments` still hid the
  fallback card (the URL is in `content`), so the file showed nowhere.
- Align the matcher with web's `packages/ui/markdown/file-cards.ts`: label
  allows backslash-escaped metacharacters (ReDoS-safe class), and the URL is
  restricted to the same allowlist (site-relative /uploads + /api/attachments/
  <UUID>/download, plus absolute http(s)); disallowed schemes stay plain text.
- Unescape the label to the real filename, then re-escape only the chars that
  would break a markdown LINK label (mobile emits `[📎 name](url)`, re-parsed
  by the renderer — unlike web's HTML data-filename), so a raw `]` never
  truncates the link text.

No dedup change: once the inline `!file` renders, hiding the standalone card is
correct. Added focused unit tests covering the escaped-label case, parens/
backslash unescape, the site-relative URL form, and disallowed-scheme rejection.

* fix(comments): clarify 409 when a comment-triggered task posts a top-level comment (MUL-4417)

A comment-triggered task that posted a parentless top-level comment on its
own issue got a 409 whose message named the required parent id but never
said top-level comments are disallowed. Agents misread it as the issue being
locked and deleted good replies trying to reset. Keep the guard (agents must
reply under their trigger comment), but make the error self-explanatory and
document the constraint in the CLI --parent help. Add handler-level tests
pinning the rejected top-level case and the allowed reply-under-trigger case.
