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.

3ce25d16e7 fix(migrate): auto-backfill attribution before migration 198 to unblock self-host upgrade (MUL-4897) (#5558)
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.

Fixes #5544

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.

7f12380f05 feat(cli): add workspace create command (#5062)
Adds `multica workspace create` (--name/--slug/--description/--context/--issue-prefix, JSON/table output). Creation does not switch the current workspace. Both --name and --slug are required to match the server contract, and the slug is immutable after creation. Docs (en/zh/ja/ko) and the CLI reference now show the executable command.

b85bb71a58 feat: custom issue properties — typed workspace-defined fields with list-surface support (MUL-4463) (#5335)
* 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.

* feat(web): custom properties settings tab + issue sidebar editors (MUL-4463)

- Settings → Properties: definition management mirroring the Labels tab
  (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
  single-key value writes, ws-updaters + realtime wiring for
  property:created/updated and issue_properties:changed.
- Locales: en/zh-Hans/ja/ko strings; Issue fixtures gain properties: {}.

* 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.

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

* 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

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.

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

* 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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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).

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

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

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

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

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

main refactored ActorAvatar.size from a raw pixel number to the semantic
AvatarSize union (packages/ui/lib/avatar-size). Switch the on-behalf-of badge
avatar from size={14} to size="xs" (16px) after merging main.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Renumbered attribution migrations to 166-172 after merging main.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

3. Security acceptance tests exercise the REAL handlers, not injected callbacks:
   - Chat: create session while invokable → revoke invoke (flip to private, keep
     owner-view) → send returns 403 + reason_code with zero chat_message / task
     writes.
   - Rerun: private historical agent through RerunIssue + canInvokeAgent — a

No migration; reason_code is a decision-time value only the manual "run now"

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Backend handler+service suites and go vet green.

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

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

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

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

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

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

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

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

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

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

* 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.

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

* 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.

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

* 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.

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

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): soften message-list scroll fade (32px → 16px)

The 32px edge fade washed out full-bleed content (HTML / image previews)
at the list edges. Halve the fade distance so it barely grazes previews
while still hinting at more content above/below.

main landed 157_agent_task_delivered_comments while this branch was open,
colliding on prefix 157 and failing TestMigrationNumericPrefixesStayUniqueAfterLegacySet.
Bump this PR's migration to the next free prefix (158). Rename only; the
migration body (nullable attachment.task_id + partial index) is unchanged.

* 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.

9d453fac1e fix(comments): clarify 409 for top-level comment from a comment-triggered task (MUL-4417) (#5292)
* 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.

Refs GH #5266.

* fix(comments): tighten 409 wording and assert the fix hint (MUL-4417)

Review nits on #5292: drop the inaccurate "while it is active" phrasing and
the redundancy from the 409 message so it matches the actual allow-set
(trigger or coalesced comment); collapse the incident narration to one line;
and assert the actionable parent_id (--parent) hint in the regression test so
the guidance can't be dropped silently.

6c3b79db19 feat(daemon): bound daemon.log size with rotation (MUL-4330) (#5170)
* feat(daemon): bound daemon.log size with rotation (MUL-4330)

The background daemon redirected its stdout/stderr into daemon.log opened
O_APPEND and never rotated it, so the file grew without limit until it was
too large to open. Every structured log line already flows through slog
(including agent subprocess stderr, forwarded via newLogWriter), so the
daemon's logger is effectively the sole author of the file's volume.

Route the foreground daemon's slog output — both the injected component
logger and the package-global slog default — through a size-based rotating
writer (lumberjack) that keeps the active daemon.log small (20MB default,
5 gzip-compressed backups, 30d), all env-overridable. Raw crash output
(Go runtime panics, pre-logger errors) now goes to a separate daemon.err.log
so the child's inherited fds never hold daemon.log open, which would block
rotation's rename on Windows.

The Desktop app spawns the daemon via this same launcher and its log tail
already handles size-shrink, so both CLI and Desktop are covered.

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

* fix(daemon): address log-rotation review — foreground output, Windows handles, bounded err log (MUL-4330)

Resolves the blocking review items on the daemon.log rotation change:

1. Windows first-upgrade rotation: a foreground managed daemon now re-points
   its own stdout/stderr to daemon.err.log at startup (SetStdHandle) before
   building the rotator, releasing any daemon.log handle an older self-update
   launcher inherited (Go opens files without FILE_SHARE_DELETE, which would
   otherwise block rename-on-rotate). No-op on Unix, where an open fd never
   blocks rename.

2. `daemon logs -f` vs rotation: Unix uses `tail -F` (reopen by name); Windows
   opens the reader with FILE_SHARE_DELETE so it can't block the rotator's
   rename, and reopens the file on size-shrink to follow across rotation.

3. Self-update handoff no longer briefly runs two rotators on one file: the old
   process closes its rotator and moves remaining handoff logs (incl. the slog
   default) to the crash sink before the successor starts.

4. daemon.err.log is now bounded: it rolls to a single ".1" backup once past
   5MB at open time, so a crash loop can't move the growth problem to it. It is
   also surfaced in the troubleshooting docs.

5. Explicit `--foreground` in a terminal keeps live stdout/stderr logging (a
   documented debugging path); only detached/background children rotate into
   daemon.log. Decided by whether stderr is a terminal.

Also: rotation env knobs now reject 0/negative (0 means 100MB / keep-all in
lumberjack), preventing an accidental unbounded config. Adds unit tests for
the err-log rolling and positive-int parsing; Windows/Linux(arm64) cross-builds
and `GOOS=windows go vet` pass.

* test(handler): bump the agent's own runtime version in quick-create parent test (MUL-4330)

TestQuickCreateIssueParentTrustBoundary bumped an arbitrary `LIMIT 1`
agent_runtime, but the handler version-checks agent.RuntimeID — the runtime
bound to the request's agent. In the shared handler test workspace, other
tests register additional runtimes, so the two diverge and the agent's real
runtime keeps the seed's empty cli_version, tripping the daemon-version gate
(422 daemon_version_unsupported) before the parent_issue_id assertions run.
Bump the runtime tied to the agent instead, making the setup deterministic.

cc3daaf3b4 fix: scope claim-time comment fetch to workspace + guard --attachment paths (MUL-4252) (#5190)
* fix(daemon): scope claim-time comment fetches to the task's workspace (MUL-4252)

The daemon claim path embeds the triggering comment and every coalesced
comment's full text into the agent prompt, but fetched them with an
unscoped `GetComment(id)` — a task row carrying a foreign comment UUID
would pull another workspace's comment text into the prompt. On a shared
SaaS backend (tens of thousands of workspaces in one DB) that is a tenant
boundary hole, latent today only because task rows are server-written.

Switch all three claim/reconcile GetComment calls to
GetCommentInWorkspace, scoped by the runtime's workspace (claim path) or
the issue's workspace (completion reconcile). The task's issue workspace
is already asserted equal to the runtime workspace, so same-workspace
delivery is unchanged; a foreign UUID now resolves to "missing" and is
skipped — matching buildCoalescedCommentData's documented behavior.

Adds DB-backed claim tests: same-workspace trigger comment is still
delivered; a foreign-workspace comment's content never surfaces.

* fix(cli): extend the workdir guardrail to --attachment paths (MUL-4252)

#5167 fenced --description-file/--content-file to the working directory
but left --attachment uncovered — the same /tmp stale-file leak in image
form: an agent that writes chart.png to a machine-shared path and attaches
it could upload another run's (possibly another workspace's) stale file.

Apply ensureAttachmentWithinWorkdir to each local --attachment path in
`issue create` and `comment add` (URL values are still skipped upstream),
reusing #5167's symlink-resolving fileWithinWorkingDir and the existing
--allow-external-file escape hatch. Rejection happens before the issue is
created, so a bad path never yields a half-created issue.

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

* fix(service): scope trigger-summary + originator resolution to the task's workspace (MUL-4252)

PR review P1: the claim-time full-comment fetch was already scoped, but
the trigger_summary snapshot (first ~200 chars) still leaked. On the real
enqueue/merge paths a foreign comment UUID flowed through
buildCommentTriggerSummary / resolveOriginatorFromTriggerComment, which
used an unscoped GetComment; the truncated text was stored on the task row
and later returned in the claim / task-history response
(handler/agent.go trigger_summary).

Thread the issue's workspace through both helpers (and their exported
merge-path wrappers) and switch to GetCommentInWorkspace, so a
cross-workspace comment resolves to "missing": trigger_summary stays NULL
and no foreign originator is inherited. Every caller already has the
issue's WorkspaceID in scope (enqueue, mention/leader, deferred fallback,
merge, completion reconcile).

Rework the claim test to drive the REAL TaskService.EnqueueTaskForIssue
path (which snapshots the summary) and assert the stored row's
trigger_summary + originator_user_id stay NULL and the claim response
carries neither the foreign body nor the foreign summary. Verified the
test fails when the summary fetch is left unscoped.

* fix(cli): validate all --attachment paths before uploading any in comment add (MUL-4252)

PR review P2: `issue comment add` checked-read-uploaded each attachment in
one loop, so a valid workdir attachment followed by an invalid (external /
symlink-escaping) one uploaded the first file — orphaning it as an
issue-level attachment — then aborted before posting the comment, and a
retry duplicated it.

Extract the URL-filter + workdir-guard + read step `issue create` already
used into a shared collectLocalAttachments helper and have comment add use
it: every attachment is validated and read up front, and nothing is
uploaded unless all pass. Adds a command-level test asserting a
valid-then-external attachment pair aborts with ZERO upload requests and
no comment (fails against the old interleaved loop).

3b7eafc3ad fix(cli): reject --description-file/--content-file paths outside the workdir (MUL-4252) (#5167)
* fix(cli): reject --description-file/--content-file paths outside the workdir (MUL-4252)

Cross-environment context leak root cause: a quick-create run wrote its
issue description to a fixed, machine-shared /tmp/desc.md. The Write
silently failed because a different environment's run had left a stale
file there, and `multica issue create --description-file /tmp/desc.md`
fed that stale content in as the new issue's description. Two profiles on
one host share /tmp even though their workdirs are isolated.

PR-1 (fail-closed guardrail + guidance):

- resolveTextFlag now rejects a --<name>-file path that resolves (after
  EvalSymlinks on both sides) outside the current working directory,
  turning "silently used another run's file" into a loud command error.
  Escape hatch: --allow-external-file. Covers issue create/update
  --description-file, comment add --content-file, and user profile
  --description-file via the single choke point.
- Templates/brief: the quick-create prompt and the runtime brief now
  require agent temp files to live inside the task workdir (never /tmp),
  and to treat a failed write as fatal.

Server, daemon, DB, and claim delivery were exonerated in the
investigation; the fix stays in the CLI and the prompt layer.

* fix(daemon): quick-create description guidance mandates --description-file for rich text

Addresses PR review (MUL-4252): the earlier "prefer inline --description"
line conflicted with the runtime brief (which prefers --description-file
for long bodies) and reintroduced the MUL-2904 risk — quick-create
descriptions are usually multi-line and carry code/quotes/backticks/$(),
which the shell rewrites or truncates when passed inline. Now: only short,
simple single-line bodies may go inline; anything multi-line or containing
special characters must be written to ./description.md and passed via
--description-file. Write-failure-is-fatal and workdir-only rules unchanged.

- Remove the runtime_brief_slim flag and the daemon-bound flag delivery subsystem built solely for it: execenv flag wiring (runtime_config_flag.go, server_snapshot_provider.go), the featureflagdispatch package, the DaemonFeatureFlagSnapshot heartbeat protocol field, and the server/daemon wiring in router.go, handler, daemon.go, main.go, cmd_daemon.go.
- Keep the generic server/pkg/featureflag engine (still used by composio_mcp_apps).
- Update tests to slim-only expectations and docs/feature-flags.md.

75695a2e40 fix(comments): guarantee at-least-once processing of user comments (MUL-4195) (#5068)
* fix(comments): guarantee at-least-once processing of user comments (MUL-4195)

Consecutive comments on an issue were silently dropped: a new comment that
arrived while the agent already had a queued/dispatched task was discarded by
the HasPendingTaskForIssueAndAgent dedup, losing the user's follow-up
instruction with no visible trace. Comments — unlike chat — are deliberate,
addressed, persisted input and must never vanish.

This makes comment handling at-least-once while keeping concurrency bounded to
one run per (issue, agent):

- Merge, don't drop (PR1): a comment landing while a not-yet-started task
  exists is folded into that task — the prior trigger becomes a coalesced
  comment and the new one becomes the trigger, so a single run still covers
  every deliberate comment. Falls back to a fresh enqueue if the pending task
  was claimed mid-flight, so nothing is lost in the race.
- Completion reconciliation (PR2): on task completion, a member comment newer
  than the run's started_at schedules exactly one follow-up via the normal
  trigger pipeline. Loop-safe: member-authored only, capped by the existing
  per-(issue,agent) dedup, and terminating.
- Visibility (PR3): coalesced_comment_ids is surfaced on the task API and in
  the run prompt so the covered comments are explicit.

Migration 145 adds agent_task_queue.coalesced_comment_ids UUID[].

Tests: merge-not-drop preserves all three of a rapid burst and repoints the
trigger to the newest; reconciliation query gates on member/since; e2e
CompleteTask enqueues a follow-up for a mid-run member comment and does not for
none.

* fix(comments): address review — originator gate, agent-scoped reconcile, cross-thread coalesced prompt (MUL-4195)

Resolves GPT-Boy's Request-changes review on PR #5068.

Must-fix #1 — merge no longer inherits a stale originator/runtime context.
MergeCommentIntoPendingTask now only folds a comment into a pending task
whose originator_user_id IS NOT DISTINCT FROM the new comment's originator.
runtime_mcp_overlay / runtime_connected_apps are a pure function of
(originator, agent) and the agent is fixed, so a matching originator keeps
the stored overlay/attribution valid; a differing originator (e.g. user B
commenting on a task originated by user A) matches no row and the caller
enqueues a fresh follow-up with B's own context instead of reusing A's.
trigger_summary is refreshed to the new trigger comment.

Must-fix #2 — completion reconcile no longer re-wakes unrelated agents.
reconcileCommentsOnCompletion computes the latest member comment's triggers
and keeps ONLY the agent that just completed, instead of fanning the comment
out through the full pipeline. An @-mention of agent B during agent A's run
is triggered once at creation time and is no longer replayed (double-run)
when A completes.

Should-fix #3 — coalesced-comment prompt no longer assumes a single thread.
The claim response now carries each folded comment's thread id / author /
created_at / content (CoalescedCommentData); the prompt embeds them directly
so the agent addresses cross-thread folded comments without the wrong
"they are in the triggering thread" hint. Old servers that ship only ids
fall back to an issue-wide fetch, still without the same-thread assumption.

Tests: TestMergeCommentIntoPendingTask_OriginatorGate (query gate),
TestCompleteTask_DoesNotReTriggerOtherAgentMentionedDuringRun (reconcile
scoping), TestBuildCommentPromptCoalescedCrossThread / IDsOnlyFallback
(prompt). Existing MUL-4195 suites still pass.

* fix(comments): close unique-index drop + dispatched-window race in comment coalescing (MUL-4195)

Second-round review follow-up on PR #5068.

Must-fix #1 — originator-mismatch no longer drops the comment.
The previous originator gate returned ErrNoRows on a different originator and
the caller fell through to a fresh enqueue, which collided with the
idx_one_pending_task_per_issue_agent unique index (one queued/dispatched task
per (issue, agent)) — silently dropping the second user's comment. Replaced
the gate with recompute-on-merge: MergeCommentIntoPendingTask now re-stamps
originator_user_id, runtime_mcp_overlay, runtime_connected_apps and
trigger_summary to the new comment's originator. A different member's comment
folds into the single coalescing run carrying the latest instruction's own
identity/overlay (no cross-user capability bleed, no drop, no collision).

Must-fix #2 — comment arriving in the claim→StartTask window is no longer lost.
Merge now targets only PRE-CLAIM states ('queued','deferred'); a
dispatched/running task is never a merge target, so a post-claim comment is
never falsely stamped into coalesced_comment_ids as "delivered". Completion
reconcile is re-anchored on dispatched_at (the moment the claim response is
built) instead of started_at, and sweeps ALL undelivered member comments since
that anchor — replaying each through the normal enqueue path so they coalesce
into one bounded, agent-scoped follow-up run. This covers the dispatch→start
window a started_at anchor missed.

Enqueue path: on a merge miss the caller no longer blindly fresh-enqueues
(which could collide with a dispatched sibling); it defers to the active
task's completion reconcile via HasActiveTaskForIssueAndAgent, and only
fresh-enqueues when no active task exists.

Tests: rewrote the query test to
TestMergeCommentIntoPendingTask_RecomputesOriginatorAndSkipsDispatched;
added TestConsecutiveCommentsDifferentOriginatorsFullEnqueuePath (full handler
enqueue path, two distinct originators) and
TestCompleteTask_ReconcilesDispatchedWindowComment (claim→start window). All
existing MUL-4195 handler/cmd-server/daemon/service suites still pass.

* fix(comments): catch pre-dispatch merge-race comment in completion reconcile (MUL-4195)

Third-round review follow-up on PR #5068.

Race: a member comment is created while the task is still queued, but its
merge loses the race to the daemon claiming the task (queued→dispatched). The
merge then finds no pre-claim row (ErrNoRows), the enqueue path defers to
reconcile — but the comment's created_at is BEFORE dispatched_at, so the
dispatched_at-anchored reconcile skipped it and the comment vanished with no
task coverage.

Fix: anchor completion reconcile on the task's created_at (which always
precedes dispatch) instead of a dispatch/start timestamp, and exclude the
run's DELIVERED SET — trigger_comment_id ∪ coalesced_comment_ids. Because
merges only ever touch pre-claim rows, that set is exactly what the claim
response carried, so any member comment created since the task was made that
is NOT in it was genuinely undelivered and earns a bounded follow-up. This
catches the pre-dispatch merge-race comment and the dispatch→start comment,
while never re-firing a comment that was delivered as a pre-claim coalesced
entry.

Test: TestCompleteTask_ReconcilesPreDispatchMergeRaceComment reproduces the
race (comment created pre-dispatch, task dispatched before merge, plus a
delivered coalesced comment) and asserts exactly one follow-up, triggered by
the race comment, with the delivered coalesced comment excluded. Existing
reconcile fixtures updated to set a realistic created_at (the production
invariant that created_at is the earliest task timestamp).

* fix(comments): merge only into the queued task, never a deferred fallback (MUL-4195)

Fourth-round review follow-up on PR #5068.

MergeCommentIntoPendingTask targeted status IN ('queued','deferred') ordered
by created_at DESC. When a (issue, agent) pair had both an older queued task
(the run about to be claimed) and a newer deferred assignee-fallback task, a
new comment merged into the deferred row instead of the queued one — so the
comment missed the imminent run and the deferred fallback could later promote
into a duplicate/conflicting run.

This merge is only ever reached when HasPendingTaskForIssueAndAgent matched a
queued/dispatched task (it never inspects deferred), so the coalescing target
must be the queued row. Restricted the merge target to status = 'queued'
(the unique index guarantees at most one). Deferred fallbacks keep their own
fire_at/promotion escalation lifecycle and are never a merge target.

Test: TestMergeCommentIntoPendingTask_TargetsQueuedNotDeferred seeds an older
queued task + a newer deferred fallback for the same (issue, agent), merges a
new comment, and asserts it lands on the queued task (trigger repointed, old
trigger coalesced) while the deferred fallback is left untouched.

22a71bafe3 feat(server): add basic LLM API layer with OpenAI-compatible endpoints (#5138)
Integrate the official openai-go SDK (v3) as a thin, reusable LLM layer
(pkg/llm) backing lightweight utility calls that do not need the agent
runtime (chat titles, quick-create drafts, ...).

Expose two user-authenticated, OpenAI-compatible chat-completions
endpoints:
  - POST /api/llm/v1/chat/completions         (JSON response)
  - POST /api/llm/v1/chat/completions/stream  (SSE stream)

Requests decode directly into the SDK's ChatCompletionNewParams and
responses are relayed via RawJSON() for byte-exact OpenAI-format
compatibility. Base URL and API key are configurable (MULTICA_LLM_*),
and the model is taken from the request with a configurable default
fallback (MULTICA_LLM_DEFAULT_MODEL, else gpt-4o-mini). When unconfigured
the endpoints return 503.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Tests: SetChatSessionPinned handler test, sortChatSessions unit tests.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

typecheck: core/views/web/desktop green. tests: chat + settings views 126 pass.

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

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

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

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

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

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

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

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

`issue reorder` takes exactly one target: --top, --bottom, --before, or
--after. That rule was a hand-rolled runtime count in runIssueReorder; declare
it with cobra's MarkFlagsMutuallyExclusive + MarkFlagsOneRequired (extracted
into registerIssueReorderFlags, shared with the tests) so cobra validates it
before RunE with canonical messages and shell completion drops the sibling
target flags once one is set.

Keep an explicit guard for no-op target values that cobra's presence check
cannot see: empty --before/--after, and --top=false / --bottom=false.

fd3216fd6b feat(lark): let an agent's owner bind/manage its Lark bot (MUL-4213) (#5079)
* feat(lark): let an agent's owner bind/manage its Lark bot (MUL-4213)

Scan-to-bind was authorized by workspace role only, so a non-admin
member could not bind a Lark bot even to an agent they own. Authorize
the device-flow install, status poll, and revoke by the same rule that
governs every other agent-management op — canManageAgent: the agent's
owner OR a workspace owner/admin.

Backend:
- router: begin/status/revoke drop to workspace-member level; the
  per-agent check moves into the handlers (agent_id is a query param /
  installation id, which the role middleware can't see).
- BeginLarkInstall + RevokeLarkInstallation load the target agent and
  run canManageAgent.
- GetLarkInstallStatus scopes the read to the session initiator or a
  workspace owner/admin; others get 404 (no existence leak). Session
  state now carries InitiatorID for this.

Frontend:
- LarkAgentBindButton takes agentOwnerId and lets the agent owner
  through (mirrors canEditAgent).
- Agent Integrations tab gates Lark per-agent (owner or admin) while
  Slack stays workspace-admin-only, since its routes are unchanged.

Tests: begin/status/revoke authorization (owner, agent owner, unrelated
member) on the backend; agent-owner bind visibility on the frontend.

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

* fix(lark): keep orphan installation revoke available to workspace admins (MUL-4213)

RevokeLarkInstallation loaded the bound agent and ran canManageAgent
unconditionally, so once the agent was hard-deleted the load 404'd and
a workspace owner/admin could no longer disconnect the orphan Lark
installation — a documented cleanup path (ListByWorkspace lists orphans;
the active-connection query filters them; Settings surfaces "Unknown
Agent" Disconnect).

Fall back to workspace owner/admin-only revoke when GetAgentInWorkspace
finds no agent; agents that still exist keep the owner-OR-admin
canManageAgent check. A plain member gains no orphan-row cleanup rights.
No FK/cascade — resolved in the application layer.

Adds a backend regression test: orphan installation is revocable by a
workspace owner but not a plain member.

fd58e13bec feat(runtimes): custom runtime names + searchable machine-grouped picker (MUL-4217) (#5070)
* feat(runtimes): custom runtime names + searchable machine-grouped picker

MUL-4217. Runtime names were daemon-generated ("Claude (host)") and
uneditable, so picking one at agent-create time was painful once a
workspace had many machines.

Phase 1 — create-agent RuntimePicker: add a search box (>6 runtimes) and
group options by machine (Local/Remote/Cloud, online-first, current
machine first) reusing buildRuntimeMachines/filterRuntimeMachines. Rows
show the provider under a machine header instead of a flat repeated list.

Phase 2 — custom names: new nullable agent_runtime.custom_name column,
never written by the registration/heartbeat upsert so the daemon can't
clobber it; display is coalesce(custom_name, name) via runtimeDisplayName.
PATCH /api/runtimes/:id gains custom_name (+ apply_to_machine to name every
runtime sharing a daemon_id in one action, owner-scoped for non-admins).
Rename UI on the runtime detail page; `multica runtime rename` CLI command.

Verified: go build/vet, sqlc, handler tests (incl. new custom-name single
+ machine-fanout), 1650 views + 764 core TS tests, typecheck, locale parity.

* fix(runtimes): address review — persist machine name on new registrations, keep custom_name in register response

Elon's review on #5070 (MUL-4217):

1. Machine name looked "lost" when a new provider registered on an
   already-named machine — the new row landed with custom_name=null and
   broke sharedCustomName. Now a fresh runtime inherits the machine's shared
   custom name at register time (ListDaemonCustomNames + sharedDaemonCustomName),
   so the machine title stays stable as providers come and go.

2. DaemonRegister rebuilt the response row by hand and dropped custom_name,
   so register returned custom_name:null — inconsistent with list/get/update.
   Both branches now carry CustomName.

Also: tighten the updateRuntime patch type to custom_name?: string (drop the
misleading `| null`, since the server treats null as "unchanged", not "clear").

Tests: register response preserves custom_name; new runtime inherits machine name.

Elon's re-review of #5070 (MUL-4217): the machine-name inheritance added
last round only covered the normal req.Runtimes path. The req.FailedProfiles
branch also upserts a daemon_id-scoped agent_runtime row (offline, profile
registration error), which shows up in the runtime list / machine grouping —
so on a named machine a failed custom-profile row landed with custom_name=NULL
and dragged the machine title back to the hostname.

Extract the inheritance into h.inheritMachineCustomName and call it from both
the normal runtime path and the failed-profile path. Add a test: named daemon
+ failed profile upsert -> the failed row's persisted custom_name is inherited.

4ed582e3bb fix(cli): reject issue list --direction when sort is position or omitted (#5072)
position (the manual board order) is always sorted ascending server-side,
so --direction was silently dropped for the default/position sort. A passed
-but-ignored flag is a footgun, especially in scripts. Reject the combination
up front with a message that names the directional sort columns instead.

b6adf23f91 feat(api): emit Content-Length header on JSON responses (#5021)
The core writeJSON helpers streamed the body via json.NewEncoder(w).Encode
after WriteHeader, which forces net/http into chunked transfer encoding and
omits Content-Length. Buffer the marshaled body first, set an accurate
Content-Length, then write — so API (and health) JSON responses advertise
their exact size. writeMeasuredJSON gets the same header. Adds a test
asserting the header matches the on-wire body length.

566d51f1c0 perf(chat): fix pending-task index mismatch + cut aggregate request storm (MUL-4159) (#5018)
* perf(chat): fix pending-task index mismatch + cut aggregate request storm (MUL-4159)

ListPendingChatTasksByCreator was a top DB hotspot. Root cause: the partial
index idx_agent_task_queue_chat_pending (migration 040) only covers
status IN (queued, dispatched, running), but migration 109 added a fourth
in-flight status (waiting_local_directory) that both pending chat queries now
filter on. Postgres can only use a partial index when the query predicate is a
subset of the index predicate, so the 4-status query stopped using it and
degraded to a Seq Scan over the whole agent_task_queue.

Implements the reviewed P0-P3 plan in one PR:

P0 index fix (split single-statement CONCURRENTLY migrations per repo convention)
- 143: CREATE INDEX CONCURRENTLY idx_agent_task_queue_chat_pending_v2 covering
  all four in-flight statuses (same column list, so GetPendingChatTask still
  benefits).
- 144: DROP the superseded 3-status index, in its own migration.

P1 SQL + handler hot path
- ListPendingChatTasksByCreator now returns cs.agent_id and states
  chat_session_id IS NOT NULL so the planner can prove the partial-index subset.
- ListPendingChatTasks filters private-agent access against the already-loaded
  accessible-agent set using the returned agent_id, dropping the extra
  ListAllChatSessionsByCreator scan on the hot path.
- Regenerated sqlc.

P2 frontend request amplification
- FAB uses the new boolean has-any query gated on enabled:!isOpen, so the
  minimised button never holds the full aggregate.
- use-realtime-sync maintains the pending aggregate (list + has-any) in place
  from task lifecycle events (queued/dispatch/running/waiting_local_directory
  -> upsert; completed/failed/cancelled -> remove) instead of invalidating on
  every chat:message/chat:done, with a debounced fallback invalidate for
  reconnect / unknown payloads.

P3 boolean endpoint
- GET /api/chat/pending-tasks/has-any backed by HasPendingChatTasksByCreator
  (EXISTS). Permission filtering is baked in via agent_id = ANY($3); an empty
  accessible-agent set short-circuits to false. The detailed list stays for the
  ChatWindow history / stop-task flows.

Tests: new handler tests cover the private-agent gate on both endpoints
(hidden from a creator who lost access, visible to the agent owner) plus the
boolean status/terminal semantics.

EXPLAIN (ANALYZE, BUFFERS) on a 300k-row reproduction:
- before (3-status index): Parallel Seq Scan, ~300k rows filtered,
  shared hit=3012, 12.1 ms.
- after (v2 index): Index Scan on idx_agent_task_queue_chat_pending_v2,
  shared hit=131, 0.07 ms.

* fix(chat): stop optimistic cross-session pending aggregate writes from workspace-fanout task events (MUL-4159)

Review on PR #5018 flagged a real privilege-escalation bug in the P2 change:
use-realtime-sync optimistically upserted the cross-session pending aggregate
(pendingTasks / pendingTasksHasAny) from chat task:* events. Those events are a
workspace fanout delivered to every member (server still BroadcastToWorkspace,
see cmd/server/listeners.go), and the payload carries no creator / agent
visibility. So member B starting a chat task could flip member A's FAB to
has_pending=true, bypassing the server-side permission filter on
/api/chat/pending-tasks[/has-any].

Fix (option 1 from the review — the self-contained one): never optimistically
write the aggregate from task:* events. On every task lifecycle transition,
debounced-invalidate the aggregate so it is refetched through the
permission-filtering endpoint, which only returns the caller's own
creator-owned, accessible-agent tasks. The per-session pendingTask cache is
still written directly — it is keyed by chat_session_id and only rendered for
sessions the user can open (server-gated), so it is not a cross-user leak.
chat:message is still excluded from aggregate refresh, so the MUL-4159 request
storm stays fixed; task transitions are per-task and coalesced by the debounce.

- Removed upsertPendingAggregate / removePendingAggregate.
- Added exported refetchPendingChatAggregate(qc, wsId) — an invalidate, never a
  setQueryData — used by the debounced handler.
- Regression tests: refetchPendingChatAggregate leaves the cached
  has_pending/list untouched (no optimistic write) and only invalidates for an
  authoritative server-filtered refetch; no-ops without a workspace id.

Verified: @multica/core + @multica/views typecheck; full core vitest suite
(752 tests) green including the 2 new guard tests.

* chore(chat): address review nits on pending-tasks endpoints (MUL-4159)

- Restore the GetPendingChatTask godoc first line that was clipped when the
  has-any handler was inserted (nit#1).
- ListPendingChatTasks short-circuits to an empty list when the caller has no
  accessible agents, mirroring HasPendingChatTasks — skips the DB round-trip
  (nit#2).
- Add a cross-creator negative test: user A's in-flight task on a
  workspace-visible agent returns has_pending=false / empty list for user B,
  locking the cs.creator_id tenant gate that the agent-visibility filter does
  not cover (nit#3).

Verified: go build ./... and go test ./internal/handler -run PendingChatTasks
(7 tests) green against live Postgres.

a69d969fb1 fix(sweeper): gate running-task wall clock on runtime liveness (MUL-4107) (#4978)
The server-side running-task sweeper failed rows purely on `started_at >
now() - runningTimeoutSeconds` (2h30m). By its own comment the wall clock
is "mainly for runs whose daemon died without reporting" and "only needs
to sit generously above any realistic single run" — but the predicate
does not actually distinguish a healthy long-running task from an
orphaned one. On self-hosted deployments this kills multi-hour research
/ training runs mid-flight even though the daemon is still heartbeating
and the run is actively producing output.

The daemon side is intentionally unbounded (only inactivity watchdogs:
idle 30m, tool 2h); the server backstop was silently the only wall
clock. `FailStaleTasks` is now AND-gated on runtime liveness:

  * dispatched — unchanged; already excludes rows with a live
    `prepare_lease_expires_at` (renewed every 15s by the daemon between
    claim and StartTask).
  * running — new: excluded when the task's `agent_runtime` row is
    `online` AND `last_seen_at` is within the runtime stale window
    (staleThresholdSeconds = 150s, the same signal
    sweepStaleRuntimes already uses).

Healthy long-running tasks on live daemons are no longer killed by the
wall clock. The daemon-dead case remains primarily handled by
sweepStaleRuntimes in the same tick (Redis LivenessStore + DB stale +
FailTasksForOfflineRuntimes); the wall-clock branch is now a defensive
backstop for the pathological case where a runtime row lingers online
with a stale DB heartbeat for longer than the wall clock. `runtime_id
IS NULL` is treated as "not proving liveness" so the wall clock still
fires on that (rare / historical) shape.

The 2h30m default is unchanged — this is a gate, not a threshold
change. Tests updated: 4 existing running-task tests now age out the
runtime so they still exercise the wall clock; 2 new tests cover both
new invariants (healthy runtime → skipped; stale runtime → still
killed).

Fixes #4958
