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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Renumbered attribution migrations to 166-172 after merging main.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Backend handler+service suites and go vet green.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Two PR #5193 review blockers:

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

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

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

Two review blockers:

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

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

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

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

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

* 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.

619b1b78e7 feat(server): remove generic LLM passthrough endpoints (MUL-4309) (#5154)
* feat(server): remove generic LLM passthrough endpoints (MUL-4309)

Remove the OpenAI-compatible passthrough HTTP handlers
LLMChatCompletions / LLMChatCompletionsStream and their two routes
(/api/llm/v1/chat/completions[/stream]) plus their tests. Exposing a
generic LLM proxy backed by the deployment key let any logged-in user
run arbitrary completions on our dime.

pkg/llm and the MULTICA_LLM_* config are kept unchanged as the
server-internal LLM entry point, so chat title generation
(maybeGenerateChatTitleAsync -> h.LLM.GenerateText) continues to work
untouched. Updated the handler.go and .env.example comments to reflect
internal-only usage.

* docs(server): fix stale comments referencing removed LLM passthrough handlers (MUL-4309)

Address GPT-Boy review nits: three doc comments still described the
deleted OpenAI-compatible HTTP proxy handlers / 503 behavior. Update
pkg/llm/client.go (package doc + ErrNotConfigured) and the Handler.LLM
field comment to describe the internal-only usage.

0c2e48ded2 refactor: retire FF_RUNTIME_BRIEF_SLIM, make slim runtime brief the only path (MUL-4297)
The runtime_brief_slim feature flag has burned in; the slim runtime brief is now the sole path.

- execenv: buildMetaSkillContent / BuildCommentReplyInstructions delegate to the slim assembler unconditionally; delete the legacy verbose brief body and writeBackgroundTaskSafetyInstructions.
- 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.

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

* 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.

a51ab4d551 feat(chat): Chat V2 — first-class IM-style Chat tab (MUL-4171) (#5076)
* feat(chat): Chat V2 — first-class IM-style Chat tab (MUL-4171)

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

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

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

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

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

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

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

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

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

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

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

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

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

Address review: give Chat its own Settings tab instead of a section inside

- 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

* 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(inbox): match chat list selected-item style (inset padding + rounded) (#5093)

Wrap the inbox list in p-1 and give each row rounded-md/px-3 so the
selected bg-accent reads as an inset rounded card — same treatment the
chat thread list already uses — instead of a full-bleed, sharp-cornered
highlight. Content stays 16px-inset (p-1 + px-3 == old px-4).

* 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.

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.

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.

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

* 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

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

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

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

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

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

Address PR 4608 review (CHANGES_REQUESTED):

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* feat(composio): per-agent allowlist + originator-scoped MCP overlay (MUL-3869) (#4736)

* feat(composio): per-agent allowlist + originator-scoped MCP overlay (MUL-3869)

Stage 3.1 of the Composio epic (MUL-3721 parent). PR #4704 wired in the
runtime_mcp_overlay column and a per-task dispatch hook; this change
inverts the default from "all-on" to opt-in and locks the overlay to the
agent owner's own connected apps:

- Agents carry composio_toolkit_allowlist TEXT[]. NULL or [] => no MCP.
  Owner-only read/write; non-owner GET/PUT silently redacts/drops the
  field (same shape as mcp_config).
- agent_task_queue carries originator_user_id UUID. Set from the
  top-of-chain HUMAN at every enqueue path:
    * issue/mention comment by member  -> author_id
    * issue/mention comment by agent   -> inherit via comment.source_task_id
                                          -> parent task originator_user_id
    * quick-create                     -> requester_id
    * chat                             -> initiator_user_id
    * retry                            -> SQL-inherited from parent row
    * autopilot                        -> NULL (system-driven)
- BuildTaskOverlay (composio dispatch) now takes (ctx, originatorUserID,
  agent) and short-circuits on five gates: invalid originator,
  originator != agent.owner_id, empty allowlist, empty intersection of
  allowlist ∩ active connections, defensive empty session URL. Composio
  CreateSession is called with BOTH `toolkits.slugs` (the intersection)
  AND `connected_accounts` (the pinned account ids), narrowing the
  tool-router twice.
- The originator-vs-owner gate closes the agent-fanout privacy hole: any
  workspace member who can @-mention a public agent used to project the
  owner's connected apps into their run. Now the overlay only mounts
  when the human at the top of the chain IS the agent owner.

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

Migration 129 up/down/up verified against docker postgres.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

e3e3e7e23f fix(realtime): bounded replay window for ShardedStreamRelay on restart (#4875)
ShardedStreamRelay shard readers previously started with lastID=,
which meant events published while a pod was down were silently lost.

Replace the  cursor with a bounded time-window start ID derived
from (now - ReplayGrace), defaulting to 5 minutes. The timestamp is
clamped to 0 to handle misconfigured clocks gracefully.

Key changes:
- Add ReplayGrace field to ShardedStreamRelayConfig (default 5m)
- Add replayStartID() helper with non-negative clamp
- Extract readShardOnce() from readShard() for testability
- Add REALTIME_RELAY_REPLAY_GRACE env var for runtime tuning
- Add regression tests for bounded cursor and replay behavior

159d9bebb1 feat(slack): route /issue slash command through quick-create (MUL-3908) (#4793)
The Slack `/issue` slash command used to directly create a raw issue: the
typed line became the title verbatim and a `todo` issue was assigned to the
agent to work on immediately. That files a rough, unstructured issue and starts
the agent on it before it is well-formed.

Switch the slash command to the quick-create pipeline instead
(TaskService.EnqueueQuickCreateTask, the same path as the web "quick create"
modal): the invoker's natural-language description is handed to the
installation's agent as a prompt, and the agent authors a well-formed issue
(proper title + structured description) in the background, attributed to the
bound member. Because creation is now asynchronous, the ephemeral reply is an
acknowledgement ("On it…") rather than a created-confirmation with a number;
the agent's completion surfaces to the invoker as a Multica inbox notification
through the shared quick-create completion path.

Installation routing and identity/membership checks are unchanged, so the same
workspace boundary and account-binding rules apply. Scope is the slash command
only — the message-based `@bot /issue` still runs through the shared
cross-platform engine (which also serves Lark) and keeps its direct-create
behavior.

- slash_command.go: swap IssueService.Create for EnqueueQuickCreateTask via a
  narrow quickCreateEnqueuer interface; prompt is the full text (no title/body
  split); drop the now-unused splitIssueText / issueCreatedText / GetWorkspace.
- router.go: wire h.TaskService instead of h.IssueService.
- tests: cover enqueue + ack, multiline prompt pass-through, empty prompt,
  unbound, non-member, inactive, team mismatch, and enqueue-failure.
- docs (4 locales): describe the quick-create behavior.

240ec4efd0 feat(slack): native /issue slash command over Socket Mode (MUL-3908) (#4780)
* feat(slack): native /issue slash command over Socket Mode (MUL-3908)

A message beginning with `/issue` is intercepted by the Slack client as a slash command and never delivered to the app, so the message-prefix /issue never worked on Slack (no event, no 👀, no issue).

Register /issue as a real slash command in the app manifest and handle EventTypeSlashCommand over the existing per-installation Socket Mode connection. It is a one-shot issue creation (no chat session / agent run) that reuses the shared IssueService and the same installation-routing + identity/membership checks as the message path, replying privately via the command's response_url (ephemeral) since a slash command has no message to react to.

Docs: register the command in the manifest and describe the slash-command behavior across all four locales.
Co-authored-by: multica-agent <github@multica.ai>

* docs(slack): add commands scope to /issue manifest; fix chat-run wording (MUL-3908)

Review follow-up: the manifest examples registered features.slash_commands but omitted the commands bot scope, so updating + reinstalling could still fail to grant the /issue command. Add - commands to oauth_config.scopes.bot in all four locales and document it in the permissions table.

Also correct the misleading "no agent run" wording in the slash-command header and router comment: a todo issue assigned to the agent still triggers it via maybeEnqueueOnAssign (issue-assignment), like the message /issue — the slash command only skips the chat session / chat run.

dbf11f0958 fix(attachments): relax frame-ancestors on local /uploads static route (MUL-3821) (#4777)
Self-hosted local-disk deployments serve document previews straight from
the public /uploads/* static route. That route inherited the global
`frame-ancestors 'none'` CSP from the middleware, so iframe-based previews
(PDF/HTML) were blocked by the browser — only the /api/attachments/*
download endpoint had been exempted (#4635 / #4679).

Serve /uploads/* through a new Handler.ServeLocalUpload that applies the
same preview security headers as the download endpoint
(setAttachmentPreviewSecurityHeaders), so the relaxed, config-aware
`frame-ancestors 'self' <configured origins>` policy applies to both
same-origin and split frontend/backend origin setups. Inline <img>
rendering is unaffected (frame-ancestors does not gate images); cloud
storage (S3/CloudFront) never hits this route.

Adds regression tests covering the relaxed CSP on /uploads and the
non-local-storage 404 guard.

3a6d3522c8 feat(slack): two-command channel reads — chat history (overview) + chat thread [id] (MUL-3871) (#4762)
Replaces the single scoped `multica chat history --scope` read with two clean
noun-commands so the agent can navigate a channel with many threads (e.g. read
the specific thread a user referred to):

- `multica chat history` — the channel OVERVIEW: recent top-level messages, each
  thread tagged with thread_id + reply_count + latest_reply (it does NOT expand
  thread contents). Backed by GET /api/chat/history + slack.History.ChannelOverview
  (conversations.history).
- `multica chat thread [id]` — read one thread: no id = the thread you're in,
  an id = a specific thread IN THE SAME channel. Backed by GET /api/chat/thread +
  slack.History.Thread (conversations.replies; DM falls back to history).

The channel stays server-pinned to the session; a thread id is only a
within-channel locator, so the security boundary (no cross-channel reads) is
unchanged. `--scope` is removed.

The prompt now teaches both commands and, via a new chat_in_thread signal
(derived from the binding: last_thread_id != last_message_id), tells the agent
which to start with — `chat history` for a top-level @mention, `chat thread` for
an in-thread one.

Tests: slack ChannelOverview/Thread (current/by-id/DM-fallback/no-binding/clamp),
handler both endpoints + auth, prompt top-level vs in-thread guidance.

50a48cef1e feat(slack): unified multica chat history pull for channel backfill (MUL-3871) (#4747)
* feat(slack): add unified `multica chat history` pull for channel backfill (MUL-3871)

Agents @mentioned in a Slack thread/channel only saw the triggering message,
never the prior conversation (GitHub #4717). Instead of force-assembling a
recent-context block on every inbound (the Feishu approach), expose a single
channel-agnostic pull command the agent runs on demand.

- channel: normalized HistoryMessage/HistoryPage/HistoryOptions vocab so the
  agent sees one shape regardless of platform.
- slack.History: resolves session -> binding -> installation -> bot token and
  reads conversations.replies (real thread) or conversations.history (DM /
  top-level channel, capturing sibling messages). thread_ts is recorded on the
  binding config at session creation to pick the right call.
- handler GET /api/chat/history: authorized purely by the task-scoped token
  (stamped X-Task-ID -> the task's own chat session), so an agent can only read
  the conversation it is currently running for.
- multica chat history CLI command (no args; same for every channel).
- buildChatPrompt nudge so the agent discovers the command.

Feishu is intentionally untouched. Adding a platform = implement the reader.

* fix(slack): require task-token actor source on chat history endpoint

Niko's review caught a privilege-boundary hole: the endpoint trusted
X-Task-ID, but it is mounted under the general Auth group where a normal
JWT / mul_ PAT request does NOT strip a client-forged X-Task-ID — only the
mat_ task-token branch stamps it. A workspace member who knew a chat task id
could forge the header and read that task's Slack channel/DM/thread history.

Gate on the server-set X-Actor-Source == "task_token" (the Auth middleware
deletes any client-supplied value and re-stamps it only on the mat_ branch),
then trust X-Task-ID. Adds a regression test: a forged X-Task-ID without the
task-token actor source is rejected with 403 and never reaches the reader.

* fix(slack): thread-first history for follow-ups, channel for first turn (MUL-3871)

A Slack conversation has two nested histories: the surrounding channel and the
agent's own thread (the bot's first reply opens a thread on the @mention). The
first version picked replies-vs-history from a thread_ts fixed at session
creation, so a session started by a top-level @mention always read CHANNEL
history — even on follow-ups inside the bot's thread, which should read THREAD
history first.

- Add a HistoryScope (auto|thread|channel). The handler resolves auto:
  first turn (no prior bot reply) -> channel; follow-up -> thread. The agent can
  override with --scope channel|thread, and the response reports the scope read.
- The thread root is derived from the binding (last_thread_id / composite-key
  suffix), available for every engaged group session, instead of the
  creation-time thread_ts (now removed from the binding config).
- A DM degrades a thread request to channel history (DMs have no threads).
- Prompt guidance + CLI help updated to explain the policy.

Tests: scope selection (thread/channel/DM-fallback/no-root), root derivation,
and handler auto-resolution (first->channel, follow-up->thread, explicit
override).

e5995c423f feat(slack): typing reaction on inbound message (MUL-3874) (#4737)
* feat(slack): add typing reaction on inbound message (MUL-3874)

Mirror the Feishu typing indicator on Slack: react with 👀 on the user's
message when it is ingested, then remove the reaction when the agent's run
finishes (EventChatDone) or fails (EventTaskFailed).

- New slack.TypingIndicatorManager: Add on ingest, Clear on terminal run
  events; state keyed by chat_session_id, bot token re-resolved from the DB on
  clear (never held in memory), all failures logged and swallowed (best-effort).
- Wire via the channel-agnostic engine.TypingNotifier seam (slackTypingNotifier
  in the ResolverSet) — the Router already calls OnIngested off the ACK path.
- Clear subscribes to the event bus directly so a failed run also drops the
  reaction (the outbound replier only handles EventChatDone).
- Skip messages older than 2m so Socket Mode reconnect replays don't restamp.

Requires the installed Slack app to hold the reactions:write scope.

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

* fix(slack): clear typing reaction when no task runs; document reactions:write (MUL-3874)

Addresses review feedback on the typing-indicator PR.

1. Stuck reaction on offline/archived agent. The debounced flush
   (flushChatRun) enqueues no task when the agent has no runtime or is
   archived (or on any enqueue/reload error), so no task lifecycle event is
   ever published and the bus-driven clear never fires — leaving the 👀 (and
   Feishu's Typing) reaction stuck on the user's message. Fix at the shared
   engine seam: add TypingNotifier.OnSettled(ctx, sessionID), which the Router
   calls from the flush on every no-task exit (before any offline/archived
   notice). Both the Slack and Feishu notifiers route it to manager.Clear, so
   the latent Feishu case is fixed too. Adds engine coverage (offline/archived
   clear, success does not) and a Slack OnSettled test.

2. Missing reactions:write scope in docs. reactions.add/remove silently fail
   without the scope, but the BYO app manifest/docs never listed it. Add
   reactions:write to the manifest + scope table and a reinstall note across
   all four locales (en/zh/ja/ko).

d970b68ce7 feat(autopilot): View/Write permission layer + member access delegation (MUL-3807) (#4695)
* feat(autopilot): add View/Write permission layer

Autopilot write and execute operations were gated only by workspace
membership, so any member could edit, delete, trigger, or rotate the
webhook of any autopilot, and GetAutopilot returned webhook tokens to
every member (a token alone can trigger the autopilot).

- Add canWriteAutopilot / requireAutopilotWrite: update, delete, trigger,
  replay-delivery, and all trigger/secret management now require the
  autopilot creator or a workspace owner/admin.
- Redact webhook_token/path/url in GetAutopilot for callers without write
  access; trigger metadata otherwise stays visible (View default = all
  members). Creating an autopilot stays open to any member.
- ANDs with the existing private-assignee-agent dispatch gate.

* feat(autopilot): delegate write access via collaborators + manage-access UI

Adds an explicit grant primitive so an autopilot's creator/admin can
authorize specific workspace members to manage it, with a frontend entry
point — beyond the implicit creator/owner-admin set from the prior commit.

Backend:
- New autopilot_collaborator table (migration 128, members-only, app-layer
  cleanup, no FK) + sqlc queries.
- memberCanWriteAutopilot now also honors explicit collaborators; the write
  gate, webhook-secret redaction, and a new per-caller can_write flag (on
  list + detail) all flow through it.
- POST/DELETE /api/autopilots/{id}/collaborators (writer-gated); GetAutopilot
  embeds the collaborators list. Delete cleans up grants in its transaction.
- Tests: grant->write->revoke flow, non-writer can't grant, non-member rejected.

Frontend (web + desktop via packages/views):
- ManageAccessDialog: member picker to grant/revoke, current list with remove.
- 'Manage access' entry in the autopilot detail header; edit/run/add-trigger/
  delete and the list-row kebab + per-trigger rotate/delete now gate on
  can_write (absent => allowed, server stays the gate).
- can_write wired through types/schema/api client/mutations; en + zh-Hans copy.

* fix(autopilot): add manage-access i18n keys to ja/ko locales

The locale parity test requires every non-EN bundle to cover every EN
key. The prior commit added detail.manage_access + the access.* block to
en and zh-Hans only, failing parity for ja and ko. Add the translated
keys to both.

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

* fix(autopilot): restrict access-list management to creator/admin only

Final-review fix: AddAutopilotCollaborator/RemoveAutopilotCollaborator
used requireAutopilotWrite, which counts granted collaborators as
writers — so a collaborator could in turn grant/revoke others, a
privilege escalation contradicting the 'collaborators cannot re-grant'
design.

- New requireAutopilotAccessManagement guard uses the narrower
  autopilotWriteByOwnership predicate (creator or workspace owner/admin
  only); swapped into both collaborator endpoints. Collaborators keep
  their edit/trigger/secret write-execute rights.
- GetAutopilot now also stamps can_manage_access (narrower than
  can_write); the detail page gates the 'Manage access' button on it so
  collaborators no longer see an entry that would 403.
- Tests: collaborator grant-others -> 403, revoke-peer -> 403, while
  retaining edit; can_manage_access true for owner, false for collaborator.

2b940046d7 fix(slack): build the binding link from the web app URL, matching Lark (MUL-3666) (#4703)
The Slack "link your account" prompt built its redeem link from
MULTICA_PUBLIC_URL, but /slack/bind is a web-app page — the link must use the
web app URL, not the backend/API URL. MULTICA_PUBLIC_URL is intentionally the
backend/API public URL (webhooks, daemon server_url, attachments); the Lark
replier already uses appURLFromEnv() (MULTICA_APP_URL ?? FRONTEND_ORIGIN).
Slack was never migrated, so on deployments that set FRONTEND_ORIGIN but not
MULTICA_PUBLIC_URL (e.g. dev) the binding prompt silently failed
("public url not configured") and @-mentions got no response.

Rename slack.OutboundReplierConfig.PublicURL -> AppURL and feed it
appURLFromEnv() in router.go, mirroring Lark. Backend/API-URL uses of
MULTICA_PUBLIC_URL (webhooks, attachments, daemon server_url) are unchanged.

63eb6f73ad feat(analytics): anonymous self-host onboarding source beacon (MUL-3708) (#4691)
* feat(analytics): anonymous self-host onboarding source beacon (MUL-3708)

Production self-host servers now report the anonymous onboarding "how did
you hear about us" channel to Multica's public write-only ingest, so the
self-host source distribution becomes visible alongside official cloud.
Official cloud keeps its existing PostHog capture unchanged; this is a
submit-time beacon, not a background telemetry pipeline.

- server/internal/sourcebeacon: ShouldSend gate (production + non-local +
  non-*.multica.ai app host, fail-closed — judged by the app/frontend host,
  not the backend URL, which official often leaves unset), per-instance
  salted hashing, deterministic event uuid, fire-and-forget sender.
- POST /api/telemetry/self-host-source: public, write-only, per-IP
  rate-limited, 4 KiB body cap, channel allowlist, strict unknown-field
  rejection. Lands in PostHog as self_host_source_channel with a
  deterministic uuid (best-effort dedup), $process_person_profile=false,
  and deployment=self_host — a distinct event name so it never pollutes the
  official onboarding funnel.
- Hook in PatchOnboarding fires once when the source is first set; never
  blocks onboarding. Only channel enum(s) + two per-instance hashes leave
  the box — never user_id/email/name/workspace/org/domain/role/use_case/the
  source_other free-text/IP.
- migration 128: system_settings singleton holding instance_salt.
- frontend: self-host-only anonymous-collection notice on the source step,
  gated by a new /api/config self_host_source_notice flag (en/zh-Hans/ko/ja).
- analytics.Event gains an optional top-level uuid; docs/analytics.md,
  SELF_HOSTING.md and .env.example document exactly what is/isn't sent and
  how to disable it (ANALYTICS_DISABLED). Also fixes the long-standing
  team_size→source drift in docs/analytics.md.

Verified locally: go build/vet, go test (sourcebeacon, analytics, handler),
pnpm typecheck (all packages), locale parity (157), step-source (6) + core
config/schema (69) vitest, lint (0 errors).

* fix(analytics): wire self-host source beacon through metrics, guard nil pool (MUL-3708)

Addresses Howard CI blockers on #4691 (no product-direction change):

- loadInstanceSalt returns "" on nil pool; salt is only loaded when
  ShouldSendFromEnv() is true, via a bounded (5s) context — restores the
  "router constructible without a DB" invariant (nil-pool routing tests).
- Add multica_self_host_source_channel_total counter (by source) + an
  IncForEvent case, so every analytics event is paired with a Prometheus
  counter. NormalizeSourceChannel reuses sourcebeacon allowlist (no 3rd copy).
- Beacon handler now builds the event via the analytics.SelfHostSourceChannel
  helper and ships it through obsmetrics.RecordEvent (no naked Capture); not
  IsMetricsOnly, so it still reaches PostHog.
- Prime the new family in the registry-families test.

Verified: go build/vet, go test ./internal/metrics ./internal/sourcebeacon
./internal/handler ./cmd/server (incl. the 3 named blockers + registry +
record-event-helper lints) all green.

11a3cf206b feat(slack): bring-your-own-app install + per-installation Socket Mode (MUL-3666) (#4566)
* feat(slack): single app-level Socket Mode connection routed by team_id (MUL-3666)

Reshape the Slack adapter from the stage-3 per-installation Socket Mode model
into the multi-tenant B2 connection model: ONE deployment-level Socket Mode
connection (app-level xapp- token, env MULTICA_SLACK_APP_TOKEN) receives the
Events API stream for every installed workspace and routes each inbound event
to its channel_installation by team_id — the existing
GetChannelInstallationByAppID routing, unchanged.

- AppConnector: the single shared connection (slack/app_connector.go). No leader
  election — per the design "one (or a few)" connections are fine: each replica
  opens one, Slack delivers each event to one of them, and the existing
  (installation, message_id) two-phase dedup guarantees exactly-once processing.
  Resolves the per-team bot user id (via the same app_id query) to detect/strip
  @-mentions, since one connection serves many workspaces.
- Inbound translation (Events API -> channel.InboundMessage) extracted to
  slack/inbound.go as free functions parameterized by the per-team bot identity.
- channel.go trimmed to the outbound Send-only sender; per-installation config
  (config.go) no longer carries an app-level token — installs hold only the
  per-workspace bot token (xoxb-) for outbound, since xapp- can't be OAuth'd.
- engine.Supervisor now skips channel types with no registered Factory, so Slack
  installs (driven by the app-level connector, not per-installation channels) no
  longer churn the lease/Build loop.
- Wiring: router.go builds the connector when MULTICA_SLACK_APP_TOKEN is set;
  main.go runs it alongside the Supervisor. Feishu untouched; channel_* schema
  unchanged.

Verified: go build ./..., go vet ./..., gofmt, and
go test ./internal/integrations/... all pass.

* feat(slack): OAuth self-serve install backend (MUL-3666)

Add the in-product OAuth install flow that creates Slack installations, the
keystone the B2 connector consumes.

- slack.InstallService: Begin (build authorize URL, seal workspace/agent/
  initiator into the OAuth state), Complete (verify state, exchange code via
  oauth.v2.access, upsert channel_type='slack' install with the bot token
  encrypted at rest, auto-bind the installer's Slack id so their first message
  is not dropped), plus List/Get/Revoke. State is stateless: sealed with the
  deployment secretbox + an embedded expiry, no session store.
- HTTP handlers (handler/slack.go): member-visible list, admin-only begin +
  revoke, and the public OAuth callback (recovers context from the sealed state,
  redirects the browser back to Settings → Integrations with a result flag).
- Routes + wiring: workspace-scoped list/begin/revoke mirror the Lark
  admin/member split; the callback is a public route like GitHub's. Built from
  MULTICA_SLACK_CLIENT_ID/SECRET (+ redirect derived from MULTICA_PUBLIC_URL,
  override MULTICA_SLACK_REDIRECT_URL; scopes via MULTICA_SLACK_SCOPES).
- Realtime: slack_installation:created / :revoked events.

Verified: go build ./..., go vet, gofmt, and go test ./internal/integrations/slack/...
all pass (new install_test.go covers state sign/verify/expiry/tamper, authorize
URL, code exchange + encrypted upsert + installer bind, and oauth error paths).

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

* feat(slack): in-product OAuth install UI for web + desktop (MUL-3666)

Add the "Connect Slack" self-serve install UI mirroring the Feishu/Lark
integration, completing the in-product install half of B2. Slack's OAuth flow
is a redirect (not a device-code QR poll), so the UI is simpler than Lark's.

- core: SlackInstallation / List / Begin types; api.listSlackInstallations /
  beginSlackInstall / deleteSlackInstallation; slackKeys + slackInstallationsOptions
  query; realtime invalidation on slack_installation:* events.
- views: slack-tab.tsx (SlackTab settings panel + per-agent SlackAgentBindButton
  + connected badge + disconnect confirm). Connect calls beginSlackInstall and
  hands the authorize URL to openExternal (system browser on desktop, new tab on
  web); Slack bounces to the backend callback which lands the install, and the
  realtime event refreshes the list. Wired into the Settings → Integrations tab
  and the agent-detail Integrations tab alongside Lark.
- i18n: en + zh-Hans settings.slack.* strings.

Verified: pnpm typecheck (full monorepo, 6/6) and pnpm lint (@multica/core,
@multica/views — 0 errors) pass.

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

* feat(slack): outbound Replier + user-binding redeem flow (MUL-3666)

Fill the stage-3 Replier=nil tail so non-installer Slack users can onboard and
get status feedback — completing B2 end to end.

- slack.OutboundReplier (engine.OutboundReplier): on NeedsBinding it mints a
  single-use binding token and DMs/replies a "link your account" prompt with the
  redeem URL (wrapped as <url|label> so formatMrkdwn doesn't mangle the
  base64url token); on AgentOffline/AgentArchived it posts a status notice; on an
  /issue-created Ingest it confirms the new issue. Plain chat stays silent (the
  agent's own reply lands via EventChatDone). Reuses the bot-token Send path and
  reads the installation row from ResolvedInstallation.Platform — no new transport.
- slack.BindingTokenService: Mint + transactional RedeemAndBind over the generic
  channel_binding_token / channel_user_binding queries (channel_type='slack'),
  mirroring lark.BindingTokenService. 15-min TTL, SHA256-hashed tokens, the
  three typed failure modes (invalid/expired, already-assigned, not-member).
- HTTP: POST /api/slack/binding/redeem (public, session-authed) maps the failures
  to 410/409/403. NewSlackResolverSet now takes the replier (nil disables it).
- Frontend: /slack/bind redeem page (packages/views/slack + apps/web route) +
  api.redeemSlackBindingToken + en/zh slack_bind copy.

Verified: go build ./..., go vet, gofmt, go test ./internal/integrations/...
(new replier_test.go covers all outcome branches + the prompt URL), plus full
pnpm typecheck (6/6) and pnpm lint (0 errors).

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

* fix(slack): address review must-fixes — connector leak, team-keyed install, /issue copy (MUL-3666)

Three fixes from Niko's review:

1. AppConnector.connectOnce leaked the Socket Mode goroutine/connection on a
   handler error: it ran sm.RunContext on the long-lived ctx and returned the
   error without cancelling it, so a transient DB/router error left the old
   connection alive (consuming events into an unread channel) while Run opened a
   second one. Each connection now runs under its own cancellable context and a
   deferred cancel + join tears it down on every exit path before reconnect.

2. Slack re-install collided with the (channel_type, app_id) unique index:
   connecting the same Slack team to a different agent failed because the upsert
   conflict key was (workspace_id, agent_id, channel_type). Add a team-keyed
   UpsertChannelInstallationByAppID (ON CONFLICT on the (channel_type, app_id)
   index, updating agent_id) and use it for the Slack OAuth install, so
   re-connecting a workspace moves the bot to the chosen agent instead of
   erroring. Feishu's per-agent upsert is unchanged.

3. /issue clarified: it is not a registered Slack slash command (no `commands`
   scope), so Slack never routes one to us. Issue creation runs through the
   message path — `@bot /issue <title>` in a channel or `/issue <title>` in a
   DM — which the engine parser handles. Documented in the connector and the
   user-facing copy (en + zh).

Verified: go build ./..., go vet, gofmt, go test ./internal/integrations/...,
make sqlc, plus pnpm typecheck (6/6) and pnpm lint (0 errors).

* fix(slack): make OAuth install transactional — agent-move binding consistency + cross-workspace guard (MUL-3666)

Address Elon's review: the team-keyed upsert kept the same installation row and
only flipped agent_id, but engine session reuse matches purely on
(installation_id, channel_chat_id) and each chat_session is permanently tied to
the agent it was created under — so after moving a Slack team from Agent A to
Agent B, existing DMs/threads kept routing to Agent A; only brand-new
channels/threads reached B. Cross-workspace re-install was worse: the SQL also
moved workspace_id while the application-layer user/chat-session bindings stayed
behind, inheriting the previous workspace's relations.

InstallService.Complete now runs one transaction (lookup → upsert → retire →
installer-bind), all application-layer per the no-FK rule:

- Look up the existing installation by team_id (config->>'app_id').
- Reject a silent cross-workspace ownership change (ErrTeamOwnedByAnotherWorkspace
  → callback redirects with slack_error=team_in_other_workspace). The owning
  workspace must disconnect first.
- On an agent change within the same workspace, retire the installation's
  chat-session bindings (new DeleteChannelChatSessionBindingsByInstallation) so
  the next message creates a fresh session under the new agent. The chat_session
  rows are preserved for history; user bindings stay valid (same users/workspace).
- Installer auto-bind moves into the tx; an already-bound-elsewhere id is a
  benign skip, a real DB error aborts the whole install.

InstallService now takes a TxStarter; the queries seam gains WithTx (dbInstallQueries
adapter) so Complete stays unit-testable with a fake tx.

Verified: make sqlc, go build ./..., go vet, gofmt, go test ./internal/integrations/...
(new tests: agent-move retire, same-agent no-retire, cross-workspace reject,
fresh-install no-retire).

* fix(slack): atomic cross-workspace install guard + green up frontend CI (MUL-3666)

Two things: address Elon's review and fix the failing frontend CI job.

Review (atomic cross-workspace guard): the previous guard was a SELECT before
the upsert, which loses the concurrent-OAuth race — two workspaces can both read
no rows, one inserts, the other's ON CONFLICT update then silently re-points the
team. Move the guard into the upsert itself: ON CONFLICT ... DO UPDATE ... WHERE
channel_installation.workspace_id = EXCLUDED.workspace_id, and map the empty
RETURNING (pgx.ErrNoRows) to ErrTeamOwnedByAnotherWorkspace. The pre-SELECT now
only feeds the agent-change cleanup. Also corrected the error copy: a team stays
bound to its first Multica workspace (revoke is soft, keeping the row + unique
index), so migration is an operator action, not "disconnect first".

CI (frontend vitest, @multica/views#test):
- The agent IntegrationsTab now renders the real SlackAgentBindButton, whose
  connected badge calls useQueryClient — absent from integrations-tab.test.tsx's
  react-query mock. Hoisted the owner/admin gate above the per-platform sections
  (one role notice instead of one per platform), made the agents members_note
  generic (en/zh/ja/ko), and updated the test (mock @multica/core/slack, stub
  SlackAgentBindButton, assert both platforms).
- Added slack-tab.test.tsx covering the real SlackAgentBindButton / SlackTab.
- locale parity: added the slack (settings) + slack_bind (common) blocks to ja
  and ko so every EN key has a translated counterpart.

Verified: make sqlc, go build ./..., go vet, gofmt, go test ./internal/integrations/...;
pnpm --filter @multica/views test (1478 pass), pnpm typecheck (6/6), pnpm lint (0 errors).

* fix(slack): surface agent-page Slack entry points when Lark is off (MUL-3666)

The agent-detail Integrations tab and the inspector's Integrations section
only considered Lark, so a Slack-only deployment (Lark disabled) showed neither
the Integrations tab nor a Connect-Slack button — the per-agent entry points
were unreachable.

- agent-overview-pane: gate the Integrations tab on Lark OR Slack configured
  (new slackInstallationsOptions query), not Lark alone.
- agent-detail-inspector: render SlackAgentBindButton alongside LarkAgentBindButton
  in the Integrations section.
- regression test: the Integrations tab appears when only Slack is configured.

Verified: pnpm typecheck (6/6), pnpm --filter @multica/views test (1478+ pass),
pnpm lint (0 errors).

* feat(slack): BYO-app install backend — paste xoxb+xapp, per-app install keyed by real app id (MUL-3666)

Adds the bring-your-own-app install path so multiple agents can each have
their own bot identity in the SAME Slack workspace (hosted B2 caps at one
agent/workspace). User pastes their app's bot token (xoxb-) + app-level
token (xapp-); we validate the bot token via auth.test, parse the real
Slack app id from the xapp- token, encrypt both tokens, and persist a
per-app installation keyed by that app id (real 'A…' ids never collide
with hosted 'T…' team ids in the existing unique index — no schema change).

- config.go: add app_token_encrypted (BYO discriminator + per-app socket token)
- install.go: extract shared persistInstall (atomic cross-ws guard + agent-move retire)
- byo_install.go: RegisterBYO + auth.test + app-id parse
- handler + route: POST /api/workspaces/{id}/slack/install/byo (admin-only)
- tests: keying, encryption, invalid tokens, auth.test failure, cross-ws, agent move

Follow-ups (separate commits): per-app Socket Mode connector that consumes
the stored app token; in-product BYO install dialog (video + paste form).

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

* refactor(slack): drop OAuth, unify on BYO per-installation model (MUL-3666)

Per product decision, Slack drops the hosted-app OAuth path entirely and
unifies on bring-your-own-app (BYO): every installation carries its OWN
app-level token and gets its OWN Socket Mode connection, so multiple agents
can each have a distinct bot identity in one Slack workspace.

- Remove OAuth install (Begin/Complete/code-exchange/sealed state/OAuthConfig/
  default scopes), the OAuth callback + begin handlers + routes, and the
  MULTICA_SLACK_CLIENT_ID/SECRET/REDIRECT/APP_TOKEN env wiring.
- Replace the single deployment-level AppConnector with a per-installation
  slackChannel (authenticated with its own xapp- token) registered as a channel
  Factory, so the engine Supervisor drives one Socket Mode connection per
  installation (exactly like Feishu). inbound/outbound/resolvers reused as-is.
- Route inbound by the event's api_app_id (== the installation's real app id),
  not team_id.
- InstallService slims to at-rest encryption + the shared persistInstall +
  list/get/revoke; install is the BYO paste path only (byo_install.go).
- Tests: drop the OAuth tests; slack + handler + engine all green.

Follow-up (frontend): replace the OAuth "Connect Slack" button with the BYO
paste dialog (the begin endpoint it calls is now gone).

* fix(slack): verify BYO bot + app tokens are from the same app, and the app token is live (MUL-3666)

Niko review: RegisterBYO only parsed the app id from the xapp string and
auth.test'd the bot token, so pasting app A's bot token with app B's app
token would 'connect' but be broken (inbound on B's socket, outbound with
A's identity). Now: resolve the bot's owning app id via bots.info (on the
bot_id from auth.test) and require it to equal the xapp's app id; and live-
validate the app token via apps.connections.open. Reject (no persist) on
mismatch or a dead app token.

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

* feat(slack): in-product BYO install dialog (paste bot + app tokens) (MUL-3666)

The OAuth begin endpoint was removed server-side, so the "Connect Slack"
button now opens a dialog where the admin pastes the bot token (xoxb-) and
app-level token (xapp-) of the Slack app they created, and submits to the
BYO install endpoint. Includes an optional setup-video link (URL constant,
left empty until the walkthrough is recorded).

- core: drop beginSlackInstall / BeginSlackInstallResponse; add
  registerSlackBYO + RegisterSlackBYORequest.
- views: SlackAgentBindButton opens the BYO dialog; refreshed comments and
  install_supported docs (now means "configured", no OAuth).
- i18n: new slack.byo_* keys + refreshed page_description in en/zh-Hans/ja/ko.
- tests: dialog submit path; views vitest (1479), typecheck, lint, locale
  parity all green.

* fix(slack): Elon review — team_id routing guard, per-agent reconnect, users:read hint (MUL-3666)

1. Inbound routing keys on api_app_id (the APP, not the Slack workspace), so
   additionally require the event's team_id to match the installation's stored
   team. A distributed BYO app installed into another Slack workspace emits the
   same app id and would otherwise mis-route to this Multica installation.
   Extracted installationServesTeam() + unit test.

2. BYO install is now agent-keyed (UpsertChannelInstallation, conflict on
   workspace_id+agent_id+channel_type): one bot per agent. Disconnect →
   reconnect a NEW app for the SAME agent now UPDATES that agent's row in place
   instead of violating the (workspace, agent, channel) unique. A unique
   violation on the (channel_type, app_id) routing index → ErrTeamOwnedByAnother-
   Workspace (the app is already connected to another agent/workspace). No
   chat-session retire is needed: a row's agent_id never changes.

3. UX: bots.info (the same-app check) needs the users:read scope — the connect
   dialog now lists the required bot scopes including it, and the error text
   says so.

Backend build/vet/gofmt/test + views vitest + typecheck + locale parity green.

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

* fix(slack): publish slack_installation:created on BYO connect; refresh stale comments (MUL-3666)

Niko final review: RegisterSlackBYO wrote the response but never published
EventSlackInstallationCreated, so only the installer's own tab refreshed —
other open clients (Settings, Agent Integrations, other tabs) did not see the
new bot in realtime, inconsistent with the revoke event and Lark. Now publishes
it on success via a small publishSlackInstallationCreated helper, with a unit
test (Bus.Publish is synchronous).

Also refreshed comments that still described the removed hosted-OAuth /
single deployment-level AppConnector model (handler SlackInstall field,
channel.go / inbound.go / outbound.go / byo_install.go). PR title updated
separately to the BYO per-installation Socket Mode model.

9e807efc62 feat(sidebar): per-workspace switcher dot + count unread per issue (MUL-3695) (#4591)
* feat(sidebar): mark which workspace has unread in the switcher dropdown (MUL-3695)

The aggregate avatar dot only says "some other workspace has unread". When
the user opens the workspace switcher they couldn't tell which one. Add a
per-row brand dot next to each OTHER workspace that has unread inbox items,
in the same right-edge slot as the active-workspace check (the active
workspace is excluded — its unread is the Inbox nav count — so dot and
check never collide on one row).

Reuses the existing cross-workspace summary data; no backend change. New
pure helper unreadWorkspaceIds() + unit tests, and AppSidebar dropdown
tests covering: dot only on the other unread workspace, no dot at count 0,
and never on the active workspace.

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

* fix(inbox): count switcher unread per issue, matching the inbox dedup (MUL-3695)

The unread-summary that drives the workspace-switcher dot counted raw
unread inbox_item rows, but the inbox UI deduplicates notifications per
issue and treats an issue as read when its NEWEST non-archived item is
read. Opening an issue marks only that newest item read (markInboxRead is
per-item; only archive cascades to siblings), so older siblings stay
unread in the DB. Result: a workspace whose inbox the user sees as empty
still lit the dot (reported on bohan-personal showing a dot for Multica AI
with no unread).

Rewrite CountUnreadInboxByWorkspace to pick the newest non-archived item
per (workspace, issue-or-id group) via DISTINCT ON and count only groups
whose newest item is unread — the exact semantics of
deduplicateInboxItems(...).filter(!read) on the client. No schema/handler
change; query-only. Adds TestInboxUnreadSummaryDedupesByIssue covering the
read-newest / unread-older case and its inverse.

54145ad72e feat(sidebar): dot the workspace switcher when other workspaces have unread inbox (MUL-3695) (#4577)
Adds a cross-workspace unread summary so the workspace switcher shows the
existing brand dot when a workspace OTHER than the active one has unread
inbox items. The active workspace's own unread stays on the Inbox nav
count to avoid a duplicate signal, and the dot is shared with the pending-
invitation indicator.

Backend: new GET /api/inbox/unread-summary returns per-workspace unread
counts for the user, scoped via a member join so a left workspace can't
light the dot. One account-level query instead of N per-workspace inbox
fetches.

Frontend: schema-guarded api.getInboxUnreadSummary, a single account-level
TanStack Query, and a derived "other workspace has unread" boolean in
AppSidebar (shared by web + desktop). Inbox WS events (new/read/archived/
batch) and reconnect invalidate the summary, so the dot appears and clears
in realtime even for events from a non-active workspace.

Closes multica-ai/multica#3773

cb6616f530 feat(slack): Socket Mode channel.Channel adapter (MUL-3516) (#4523)
* feat(slack): Socket Mode channel.Channel adapter (MUL-3516)

First slice of the Slack adapter: implements channel.Channel (Type/Connect/Disconnect/Send/Capabilities) over Slack Socket Mode, normalizes inbound events to channel.InboundMessage (DM, channel @mention, thread reply; bot-loop + edit/delete guards), decodes the per-installation config/secret blob, and registers the Factory under TypeSlack. No engine, core, or channel_* schema change. Unit-tested (translation, capabilities, config decode, chunking, Send via httptest). Resolvers + engine wiring + Block Kit binding replier follow.

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

* fix(slack): address adapter review (MUL-3516)

- Propagate InboundHandler errors through dispatchEventsAPI/handleSocketEvent to Connect so an infra failure tears down the connection for Supervisor reconnect/backoff instead of being silently swallowed (ACK still happens first).
- Capabilities: declare only CapText | CapThreadReply; drop CapRichCard/CapAttachment/CapMessageEdit until those Send paths are wired.
- slackChatType: map mpim (multi-party DM) to group, not p2p, so the 'must address bot' filter applies; only 1:1 im is p2p.
- Document the group-addressing decision: explicit @bot mention required in groups; mention-free thread continuation deferred to the session-aware layer.
- Tests: handler-error propagation, slackChatType table, mpim-requires-mention, capabilities negative assertions.

* refactor(channel): shared channel-agnostic ChatSession service (MUL-3516)

Extract the session/append//issue machinery — currently locked inside the Feishu-pinned lark.chatSessionService — into a shared engine.ChatSession parameterized by channel_type + session titles, so every IM adapter reuses it instead of re-implementing it. Logic is verbatim (find-or-create session+binding with unique-violation race re-read; append+touch+reply-target+in-tx dedup Mark; /issue parse with bare-command previous-message fallback) but channel-neutral: command-parse source is supplied by the adapter (enrichment is platform-specific). Backed by a narrow SessionQueries interface so it is unit-tested with an in-memory fake (no DB). /issue parser moved to engine.ParseIssueCommand. Next: migrate Feishu onto it and wire Slack's ResolverSet, removing the lark duplicate.

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

* fix(channel): decouple session binding key from outbound target (MUL-3516)

Addresses Elon's round-2 review. engine.ChatSession.EnsureSession previously keyed the binding on a raw chat id (EnsureSessionInput.ChatID), so a resolver wiring Slack straight through would collapse every @bot thread in one channel into a single chat_session and overwrite last_thread_id. Make the API un-misusable:

- EnsureSessionInput.ChatID -> BindingKey: the explicit session-isolation key (Feishu: chat id; Slack DM: channel id; Slack channel: channel id + thread root), documented so a raw threaded-platform chat id is never passed straight through.
- Add EnsureSessionInput.BindingConfig (opaque) persisted on the binding's config column, so the real outbound channel/thread is preserved when BindingKey is composite — outbound routing stays separate from the isolation key.
- channel.sql CreateChannelChatSessionBinding now writes config (additive, uses the existing NOT NULL column; lark caller passes '{}', no schema change, no Feishu regression).
- Tests: TestEnsureSession_ThreadRootIsolation (two thread roots in one channel -> two sessions; same root reuses) and TestEnsureSession_StoresBindingConfig.

No production wiring change yet (per review, the not-yet-wired shared service is an accepted preparatory state); this makes the API correct before Feishu/Slack are migrated onto it.

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

* feat(slack): Slack ResolverSet with thread-root session isolation (MUL-3516)

Wires Slack into the channel-agnostic engine.Router via a ResolverSet built on the generic channel_* queries (installation route by team_id, identity + workspace-membership recheck, two-phase dedup, audit) plus the shared engine.ChatSession. No new query, no schema change.

slackSessionRouting is the per-message isolation rule (Elon round-2 / Niko round-3): a DM is one session per channel; a channel/group message is isolated by thread root (key = channel:threadRoot, root = inbound thread_ts or the message ts for a top-level @mention), so two @bot threads in one channel are two sessions. The real channel id rides in BindingConfig for outbound; the reply thread is returned separately. Tests cover DM/channel/thread routing, config, and that distinct thread roots isolate while a same-thread follow-up reuses its key.

Not yet wired into router.go (still a preparatory commit, per review); Feishu migration onto the shared service, router/config wiring, and the Slack outbound path follow.

* feat(slack): Markdown->mrkdwn outbound formatting (MUL-3516)

Slack renders mrkdwn, not Markdown, so an unconverted agent reply shows literal ** , ## and [text](url). Add formatMrkdwn — a faithful Go port of Hermes Agent's slack format_message (MIT) — and apply it in slackChannel.Send before chunking/posting. Protects fenced+inline code, converted links, and existing Slack entities behind placeholders; converts headers/bold/italic/strike/links; escapes control chars. Unit tests cover each construct plus fenced-code protection and a link nested in bold.

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

* docs(slack): preserve Hermes MIT notice for ported mrkdwn converter (MUL-3516)

Addresses Niko's review. formatMrkdwn is a substantial port of Hermes Agent's slack format_message; MIT requires preserving the copyright + permission notice. Add the full Hermes MIT copyright/permission notice + source URL as a header on mrkdwn.go (no repo-level third-party notice file exists, and the header cannot get separated from the ported code). Also add the suggested Send-layer regression test (TestSend_AppliesMrkdwn) that pins the wiring: slackChannel.Send converts Markdown to mrkdwn before posting.

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

* refactor(lark): migrate Feishu onto shared engine.ChatSession, drop duplicate (MUL-3516)

Completes 'every IM reuses one shared session service' and removes the dual-path the reviewers flagged as temporary. Feishu's ResolverSet now drives the channel-agnostic engine.ChatSession (channel_type=feishu, Lark session titles preserved) instead of the Feishu-specific lark.chatSessionService, which is deleted. Behavior is unchanged: engine.ChatSession is the verbatim port of the old logic and is unit-tested; the new Feishu binder param-mapping (BindingKey=chat id, CommandText=un-enriched CommandBody from Raw) is covered by feishu_resolvers_test.go.

- Delete chat_service.go (chatSessionService + helpers) and issue_command.go/_test.go (parser now engine.ParseIssueCommand). Relocate the shared TxStarter interface to tx.go (still used by binding-token + registration services).
- chat.go keeps only the AuditLogger seam; remove the now-dead ChatSessionService / EnsureChatSessionParams / AppendUserMessageParams / AppendResult / IssueCommand types.
- router.go constructs engine.NewChatSession for Feishu; inbound_enricher_test + doc.go updated.

make-test parity: go build ./..., go vet, gofmt, and go test ./internal/integrations/{lark,channel/...,slack} all pass (full Feishu suite green).

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

* feat(slack): wire Slack adapter + ResolverSet + outbound into router (MUL-3516)

Activates the full Slack pipeline, gated by MULTICA_SLACK_SECRET_KEY (the bot/app-token decryption key). When unset the block is skipped, so existing deployments are unaffected and Feishu is untouched.

- router.go registers slack.RegisterSlack (Socket Mode connect/send Factory) + channelRouter.Register(TypeSlack, NewSlackResolverSet) (inbound pipeline) + slack.NewOutbound(...).Register(bus) (outbound).
- New slack/outbound.go: an EventChatDone subscriber mirroring the Feishu Patcher. It finds the Slack chat binding for the finished session, recovers the real channel from the binding config (the channel_chat_id may be a composite thread-isolation key) + the reply thread from last_thread_id, and posts via slackChannel.Send (reusing formatMrkdwn / chunking / threading). Sessions with no Slack binding are ignored, so it coexists with the Feishu Patcher on the shared bus.
- Tests: posts to the bound channel/thread with the real channel id; ignores non-Slack sessions, empty completions, revoked installations, and non-chat events.

Slack now shares engine.ChatSession, channel_* tables, IssueService and TaskService with Feishu. Remaining: config-driven installation provisioning (an operator currently creates the channel_type='slack' row; the config block shape — which workspace/agent — is a product decision) and a live end-to-end smoke. go build ./..., go vet, gofmt, and go test ./internal/integrations/{slack,channel/...,lark} all pass.

5e824a94ae chore(channel): remove the one-time MULTICA_LARK_HUB_DISABLED cutover switch (#4527)
The lark_*->channel_* cutover (MUL-3515) is deployed to prod, and the
MULTICA_LARK_HUB_DISABLED park-switch was a one-time scaffold for that
rollout — the end state intentionally does not use it (prod never set the
env). Remove the env-gated branch from cmd/server/main.go so the channel
supervisor always starts when built; its existing nil-guard and shutdown
join are unchanged. Trim migration 124's now-obsolete switch runbook to a
short historical note (comment-only; 124 is already applied, so this does
not re-run).

3e21e58df0 feat(channel): channel-agnostic engine (Supervisor + Router); Feishu as channel.Channel (MUL-3620) (#4512)
* feat(channel): add channel-agnostic engine Supervisor (MUL-3620)

Stage-1 (MUL-3515) shipped the channel abstraction but nothing drove it.
Add the generic engine that does:

- channel.InboundHandler + Config.Handler: the single shared inbound entry
  the engine injects into every adapter (Hermes set_message_handler model).
- channel.Channel.Connect now blocks for the connection lifetime (doc), so
  the supervisor can tie lease renewal to connection liveness.
- new package channel/engine: Supervisor, generalized out of lark.Hub. It
  enumerates active installations across ALL channel types (no hard-coded
  feishu), fences each behind the WS lease CAS, builds the platform Channel
  via channel.Registry, drives Connect/Disconnect with backoff+jitter, and
  restarts on credential rotation. Knows nothing about any platform.

channel.Channel is now driven by an engine; integrations/channel has an
external consumer. Feishu adapter + boot cutover follow next.

Tests: supervisor_test.go covers lease CAS, reclaim, reap-on-revoke,
rotation restart + token fencing, backoff on build error, lease-loss
teardown, bounded release, shutdown timeout. Race-clean.

* feat(lark): drive Feishu through the channel engine; remove lark.Hub (MUL-3620)

Refactor Feishu into the first channel.Channel and cut boot over to the
channel-agnostic engine.Supervisor, removing the Feishu-only Hub.

- feishuChannel implements channel.Channel: Connect runs the existing
  WS long-conn connector for one installation; Send posts a text reply
  via the Lark IM API; Capabilities declares Feishu's feature set.
  RegisterFeishu wires it to channel.TypeFeishu — adding a platform is
  now 'register a Factory', no engine edit.
- FeishuRuntime extracts the former Hub.handleEvent / scheduleReply:
  runs the Dispatcher and drives the detached typing indicator +
  OutcomeReplier off the connector ACK path. main.go drains it on
  shutdown after the supervisor stops delivering events.
- channelInstallationStore (engine.InstallationStore) enumerates active
  installations across ALL channel types via the new de-hardcoded query
  ListAllActiveChannelInstallations; the Supervisor routes each row to
  its registered Factory by channel_type. Generic per-row fingerprint
  replaces the feishu-specific one.
- boot: engine.Supervisor replaces lark.Hub.Run; MULTICA_LARK_HUB_DISABLED
  keeps its name for runbook compatibility.
- delete hub.go / hub_pgx.go / hub_test.go; relocate the connector
  contract (EventConnector/EventEmitter), uuidString, and the reply-path
  tests (-> feishu_runtime_test.go) so coverage is preserved.

No channel_* schema change. Feishu behaviour unchanged; lark + channel +
engine tests green under -race; go build/vet ./... clean.

Remaining (follow-up): lift the Dispatcher pipeline into a channel-
agnostic engine.Router over channel.InboundMessage + resolver interfaces,
so the inbound core stops being Lark-shaped and adding a channel needs
zero core edits (validated by Slack, MUL-3516).

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

* feat(channel): add channel-agnostic engine.Router (inbound pipeline) (MUL-3620)

Generalize lark.Dispatcher's inbound pipeline into engine.Router: the single
shared channel.InboundHandler the Supervisor injects into every Channel. It
routes by ChannelType to a registered ResolverSet and runs the same ordered
pipeline for every platform (install route -> two-phase dedup -> group @bot
filter -> identity+membership -> ensure session -> append+mark -> /issue ->
debounced run), then drives the detached OutboundReplier + typing indicator.

Platform specifics live behind resolver interfaces (InstallationResolver,
IdentityResolver, Deduper, SessionBinder, Auditor, OutboundReplier,
TypingNotifier) + shared services (IssueCreator/TaskEnqueuer/SessionReader).
Adding a platform is 'register a ResolverSet', not 'edit the Router'. Outcome
/ DropReason values match the legacy lark ones 1:1.

Additive: lark.Dispatcher untouched and still wired; the feishu ResolverSet,
the cutover, and the old-path removal land next. channel.InboundMessage gains
ForceFresh (the normalized /fresh affordance). Batcher moved into engine.

router_test.go covers the pipeline invariants (routing, dedup finalize
states, group filter, identity, membership, ensure/append, /issue, debounce,
flush offline, force-fresh, drain) with generic fakes; race-clean.

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

* feat(lark): cut Feishu over to engine.Router; remove lark.Dispatcher; core no longer Lark-shaped (MUL-3620)

Wire the channel-agnostic engine.Router (added in the prior commit) as the
shared inbound handler and refactor Feishu into a ResolverSet, completing the
generic-engine cutover. The inbound core (engine.Router) now contains zero
platform specifics.

- Feishu ResolverSet (feishu_resolvers.go): InstallationResolver,
  IdentityResolver, Deduper, SessionBinder, Auditor, OutboundReplier,
  TypingNotifier — each backed by the existing ChannelStore / ChatSessionService
  / OutcomeReplier / typing indicator, translating at the channel.InboundMessage
  boundary (platform fields read from Raw). origin_type stays 'lark_chat'.
- feishuChannel now produces a normalized channel.InboundMessage and hands it to
  the engine handler via channel.Config.Handler; the old Raw round-trip through
  lark.Dispatcher is gone.
- Remove lark.Dispatcher, FeishuRuntime, and lark's pending_batcher (the engine
  owns the pipeline + batcher now); their behavioural coverage moved to
  engine.Router tests. Surviving native types (InboundMessage / Outcome /
  DispatchResult) relocated to feishu_types.go.

elon review nits addressed:
- The channel engine (Registry + Router + Supervisor) is now built
  UNCONDITIONALLY, outside the MULTICA_LARK_SECRET_KEY gate, so a non-Lark
  deployment runs it; Feishu registers its Factory + ResolverSet only when its
  key is present.
- channel.Config.Raw is now genuinely the platform config JSONB
  (channel_installation.config): the feishu factory builds a credentials-only
  Installation from it, and the workspace/agent identity is resolved per message
  by the Router — no full-db-row marshaling.
- feishuChannel gains direct unit tests: factory config decode, Send text +
  reply-target mapping, Capabilities, inbound normalization + Raw round-trip,
  msg-type + result mapping.

No channel_* schema change. go build/vet ./... clean; channel + engine + lark
green under -race. Feishu behaviour preserved (pipeline logic lifted verbatim,
only generalized).

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

* docs(channel): fix stale comments on the channel engine boot (MUL-3620)

Address Elon's review nit: three comments still described the pre-cutover
behavior.

- handler.go: ChannelSupervisor is built UNCONDITIONALLY now, not nil when
  MULTICA_LARK_SECRET_KEY is unset.
- main.go: same — the supervisor always exists; only MULTICA_LARK_HUB_DISABLED
  parks it.
- router.go: with no platform registered the store still lists active rows;
  Registry.Build returns ErrUnknownType and the supervisor backs off (it does
  not 'find no installations').

Comment-only; no behavior change.

af34b8f83a feat(lark): add proxy support for WebSocket connections (#4166)
Add ProxyURL field to GorillaDialer so deployments behind a corporate
proxy can route Lark WebSocket connections through an HTTP CONNECT proxy.

- GorillaDialer.ProxyURL: optional proxy URL parsed and applied to the
  underlying gorilla/websocket dialer before each DialContext call.
  Empty value preserves the default ProxyFromEnvironment behaviour.
- Router reads MULTICA_LARK_WS_PROXY_URL env var and sets it on the
  production dialer.
- Three new unit tests cover invalid URL, proxy-applied, and empty-URL
  default paths.

Closes #4032

8ad673fdb7 MUL-3560: gate slim runtime brief behind runtime_brief_slim feature flag (#4449)
The MUL-3560 slim runtime brief — kind-driven dispatcher, per-section
gating, prose compression for ~7k chars saved on the typical
comment-triggered task — now ships behind the `runtime_brief_slim`
feature flag wired via the framework-level service from MUL-3615.

Default: OFF in every environment (production stays on the legacy
brief that has shipped for ~2 years). Staging opts in via the YAML
rule set; ops can override per-process with `FF_RUNTIME_BRIEF_SLIM=true`.
Production is held back until staging has burned in long enough that
we are confident the slim brief does not regress agent behaviour.

Architecture (one toggle point, two code paths, both fully tested):

  buildMetaSkillContent (runtime_config.go)
      │
      └─ useSlimBrief() → false (default)
      │     → fall through to the legacy verbose body that ships on
      │       main today — byte-for-byte unchanged, no migration risk
      │
      └─ useSlimBrief() → true
            → buildMetaSkillContentSlim (runtime_config_sections.go)
              → classifyTask → 5-way kind switch → per-section writers

BuildCommentReplyInstructions takes the same gate, so the per-turn
comment prompt and the runtime brief stay in sync on which template
they emit.

What's in this PR:

- runtime_config_flag.go (new): package-scope `runtimeFlags` atomic
  pointer + `SetFeatureFlags` setter + `useSlimBrief` toggle point.
  Nil-safe: a daemon that forgets to wire the service falls back to
  legacy, no panic.
- runtime_config_kind.go (new): `taskKind` enum + `classifyTask` +
  `hasIssueContext` predicate. Used only by the slim path.
- runtime_config_sections.go (new): the slim brief itself —
  `buildMetaSkillContentSlim` + per-section `writeXxx` helpers
  + `writeAvailableCommandsQuickCreate` minimal variant +
  `writeBackgroundTaskSafetySlim` compressed safety section. The
  Section × Kind matrix is documented inline on
  `buildMetaSkillContentSlim` and the test below checks the
  dispatcher does not diverge from the spec.
- reply_instructions.go: `BuildCommentReplyInstructions` gains a
  short slim-or-legacy prelude; new `buildCommentReplyInstructionsSlim`
  is the compressed cookbook (defers the shell-hazard rationale to
  `## Comment Formatting`).
- runtime_config.go: `buildMetaSkillContent` gains a 2-line
  dispatcher at the top; the legacy body is otherwise untouched.
- runtime_config_kind_test.go (new): canaries for both paths.
  - TestClassifyTask: 5 kinds + 3 tiebreak cases.
  - TestTaskKindHasIssueContext: predicate semantics.
  - TestSlimFlagOffUsesLegacy: nil flag service → legacy path
    (renders "Get full issue details.", a legacy-only substring).
  - TestSlimFlagOnUsesSlim: flag on → slim path (renders "full
    issue.", a slim-only one-liner) AND must NOT render legacy
    "Get full issue details.".
  - TestBuildMetaSkillContentSlimKindMatrix: locks the per-kind
    section set; heading match is line-anchored so inline references
    don't trip absence assertions.
  - TestSlimQuickCreateAvailableCommands: locks the minimal-variant
    content for quick-create (issue create present, every other
    Core command absent).
  - TestSlimBriefIsSubstantiallyShorter: ≥ 30% reduction guard so
    a future change can't accidentally re-bloat the slim path back
    to legacy levels.
- cmd/server/main.go: now calls `execenv.SetFeatureFlags(flags)`
  immediately after constructing the feature flag service.

Measured impact (slim vs legacy, claude provider, realistic fixture
with 2 repos + 2 skills + member initiator):

    legacy = 19567 chars
    slim   = 11868 chars    Δ = -7699  (-39.3%)

Verification:

- go vet ./internal/daemon/... ./cmd/server/...                  ok
- go test ./internal/daemon/...                                  ok
- go test ./pkg/featureflag/...                                  ok
- TestSlimBriefIsSubstantiallyShorter logs the 39.3% ratio
- TestSlimFlagOffUsesLegacy + TestSlimFlagOnUsesSlim pass both
  directions, so the dispatcher is locked in code.

The pre-existing `internal/handler` test failures
(TestLeaveWorkspace_RevokesOwnRuntimes,
TestDeleteMember_CancelsTasksFromAgentReassignment,
TestDeleteMember_NoRuntimes_DeletesMember) reproduce on plain
`origin/main` with the same `relation "channel_user_binding" does
not exist` SQL error — they are a missing-migration bug from the
recent channels foundation PR (ce28d0aa0), not anything this PR
touched.

Rollout plan:

1. Merge this PR. Production daemons keep emitting the legacy brief
   (flag default false).
2. Add a YAML rule to staging's
   `MULTICA_FEATURE_FLAGS_FILE`:

       runtime_brief_slim:
         default: true

   Staging daemons start emitting the slim brief on next restart.
3. Watch `agent prompt prepared` logs + agent behaviour for 7 days.
4. If staging is clean, flip the prod YAML to `default: true`.
   Legacy code path stays in the binary as a kill-switch
   (`FF_RUNTIME_BRIEF_SLIM=false` to revert without a deploy).
5. After ~30 days clean in prod, follow up with a PR that deletes
   the legacy body and the flag — same pattern as docs/feature-flags.md
   recommends ("plan the death of the flag at birth").

4a8210912a feat(featureflag): framework-level feature flag system (MUL-3615) (#4496)
* feat(featureflag): framework-level feature flag system (MUL-3615)

Introduces a reusable feature flag framework so future features can adopt
flags without writing infrastructure code.

Backend: server/pkg/featureflag (Go)
- Service / Provider / Decision separation per Martin Fowler's Toggle
  Point / Toggle Router / Toggle Configuration pattern.
- Providers: StaticProvider (rules in source control), EnvProvider
  (FF_<KEY> overrides for ops kill switches), ChainProvider
  (first-hit-wins composition).
- EvalContext carried through context.Context with WithEvalContext /
  EvalContextFrom; supports user_id, workspace_id, free-form attributes.
- PercentRollout via deterministic FNV-1a bucketing; same user always
  lands in the same bucket so experiments do not flap between requests.
- Nil-safe Service: a nil *Service or missing flag returns the caller's
  default so business code never panics on a missing flag.
- 100% unit-test coverage with -race; go vet clean.

Frontend: packages/core/feature-flags (TypeScript)
- Same vocabulary as the Go side (Decision, EvalContext, Rule,
  PercentRollout). FNV-1a parity ensures cross-tier bucket agreement.
- FeatureFlagService + StaticProvider + ChainProvider in pure TS.
- React glue: FeatureFlagsProvider, useFlag(key, default),
  useVariant(key, default). Hooks fall back to the default when no
  provider is mounted so Storybook / unit tests stay simple.
- Vitest tests for service, providers, hash, and React hooks.

Docs: docs/feature-flags.md — wiring, EvalContext, toggle points,
backend-protection note, and the standard best-practice checklist.

The framework intentionally has no third-party Go deps and no API
surface beyond what real callers will need. New providers (DB, remote
config, LaunchDarkly) plug in by implementing Provider; no existing
caller has to change.

* fix(featureflag): cross-tier hash parity + variant only when enabled (MUL-3615)

Two must-fix issues from the PR review on #4496:

1. TS hash had a trailing zero separator that Go did not emit, so the
   same (key, identifier) bucketed differently on the two tiers. The
   "user lands in the same bucket on server and client" promise was
   broken. For example billing_new_invoice/user-42 was bucket 97 in Go
   and bucket 11 in TS.

   Fix: TS fnv1a now emits the zero separator BETWEEN parts only, never
   after the last one, matching Go's hash.Write byte stream exactly.
   Verified by parallel golden tests on both sides that pin five
   (key, identifier) -> bucket triples; if either side drifts both tests
   fail and one must be brought back in sync.

2. StaticProvider returned `Rule.Variant` regardless of whether the rule
   evaluated to enabled=true. A 0%-rollout user, a deny-listed user, or
   a default-off user would see variant="experiment-v2", so callers
   branching on Variant() would route control users into the experiment
   arm.

   Fix: Rule.Variant is now the ON-variant only. When the rule evaluates
   to enabled=false the Decision's variant is the canonical "off",
   regardless of what Rule.Variant says. Documented as a behavior
   contract in the Rule godoc / JSDoc and covered by regression tests
   on both sides.

Tests: - go test -race ./pkg/featureflag/...  : all green (1.58s).
  - pnpm --filter @multica/core test     : 661/661 (3 new).
  - pnpm --filter @multica/core typecheck: clean.

* fix(featureflag): hash UTF-8 bytes on the TS side for cross-tier parity (MUL-3615)

Follow-up review on PR #4496 caught that the previous hash fix was only
correct for ASCII input. The TS side used `charCodeAt`, which returns
UTF-16 code units, while the Go side hashes the UTF-8 byte
representation. Any non-ASCII flag key or identifier — Chinese flag
names, accented user IDs, emoji — would bucket differently on backend
vs frontend, silently breaking the "same user, same bucket" promise the
PR description makes.

Concretely:
  flag/é         Go 53  vs TS-old 68
  flag/🦄        Go 82  vs TS-old 75
  实验/user-1    Go 90  vs TS-old 4
  flag/用户-1    Go 95  vs TS-old 2

Fix: replace per-char charCodeAt with a module-level `TextEncoder`
('utf-8') and hash each encoded byte. After the fix all four cases above
match Go exactly, and the existing ASCII cases continue to match.

The cross-language golden tables on both sides now include the 5 new
non-ASCII cases alongside the 5 ASCII cases, so any future regression
that swaps UTF-8 for charCodeAt (or vice versa) will fail loudly on
both Go and TS simultaneously.

TextEncoder is part of WHATWG Encoding and is available in every
evergreen browser, in Node 11+, and in Hermes (React Native) >= 0.74,
which covers every runtime that imports @multica/core/feature-flags.

Tests: - go test -race ./pkg/featureflag/...   : all green.
  - pnpm --filter @multica/core test      : 661/661.
  - pnpm --filter @multica/core typecheck : clean.

* feat(featureflag): wire into main app config — YAML file + env override (MUL-3615)

Follow-up requested by Yushen on PR #4496: make the feature flag
framework configurable through the existing main-program config system
instead of requiring Go code edits. multica's main app is purely env-var
driven (see .env.example) with optional MULTICA_*_FILE knobs for richer
config; feature flags now follow the same pattern.

server/pkg/featureflag/config.go
  - LoadRulesFromYAMLFile(path) parses a YAML rule set into runtime
    Rule structs. Empty files are a valid "no flags yet" state; missing
    or malformed files surface a hard error so operators see misconfig
    the same way DATABASE_URL parse errors do.
  - NewServiceFromEnv composes the standard provider chain:
      1. EnvProvider("FF_")               (runtime kill-switch path)
      2. StaticProvider from YAML file    (declarative rule set)
    When MULTICA_FEATURE_FLAGS_FILE is unset, only the env layer is
    active and every IsEnabled call falls through to the caller's
    default, so the server can boot before any flag is authored.

server/cmd/server/main.go
  - Construct the Service once at startup right after env-var warnings,
    fail loudly on malformed YAML, log the loaded rule count via the
    Service logger. The Service is held in a local `flags` variable
    ready to be threaded into handler.Handler / service constructors
    when the first flag user lands. Threading is deferred to the PR
    that adds the first business consumer so this PR stays a pure
    framework + config layer.

.env.example
  - New "Feature flags" section documents MULTICA_FEATURE_FLAGS_FILE and
    the FF_<KEY> override convention, with a minimal YAML schema example
    inline.

docs/feature-flags.md
  - Replace the "build a provider manually" example with the
    NewServiceFromEnv pattern that now matches what main.go actually
    does. Show the YAML schema in one place. Note the on-variant /
    off semantics from the previous review round.

server/pkg/featureflag/doc.go
  - Update package doc to mention the gopkg.in/yaml.v3 dependency
    (already a server-level dep) instead of the now-inaccurate
    "no third-party dependencies" claim.

Tests: - go test -race -count=1 ./pkg/featureflag/...   all green; new
    config_test.go covers: simple YAML, full-shape YAML, empty file,
    missing file, malformed YAML, no env var, file-only, env-beats-file,
    bad file surfaces error.
  - go test -race -count=1 -run TestHealth ./cmd/server/...   sanity
    check that the main.go boot path with the new wiring still passes.
  - go vet ./...   clean.

00b9668cd2 fix(autopilot): cold-start planner honors trigger.last_fired_at (MUL-3551) (#4495)
Post-deploy of the new scheduled-dispatch scheduler (PR #4444), an
autopilot configured for "weekdays 17:10 Asia/Shanghai" fired at
~12:30 Beijing the day after deploy — ~4h 38m before the next
scheduled time the UI showed. Traced to a cold-start regression in
the planner hook:

Old behaviour
-------------
On the first tick after migration the hook found no
`sys_cron_executions` row for the trigger
(`latestPlan(...).Found == false`) and anchored on the trigger's
`created_at`, then applied the 24h replay cap:

  after := cfg.CreatedAt
  if oldest := now.Add(-replayWindow); after.Before(oldest) {
      after = oldest // now - 24h
  }

For a trigger created days/weeks earlier and last fired by the
legacy goroutine at Mon 17:10 Beijing (= Mon 09:10 UTC), this set
`after = Tue 04:13 UTC - 24h ≈ Mon 04:13 UTC`. The half-open
enumeration `(Mon 04:13 UTC, Tue 04:13 UTC]` STILL contained Mon
09:10 UTC — the occurrence the legacy code had already handled —
so the new scheduler dispatched it again the moment it took over.
The result: a SCHEDULED-source autopilot_run with planned_at = Mon
17:10 Beijing but a wall-clock dispatch at Tue ~12:30 Beijing.

Timezone math was correct; the bug was purely the cold-start
anchor not respecting prior-fire history.

Fix

Co-authored-by: multica-agent <github@multica.ai>
---
The `autopilot_trigger.last_fired_at` column is maintained by both
the legacy goroutine and the new scheduler (via
TouchAutopilotTriggerFiredAt), so it is the authoritative
"most-recent successful fire" cursor across the migration boundary.
The planner hook now anchors cold-start enumeration on it:

  case latest.Found:        after = latest.PlanTime
  case lastFiredAt != zero: after = lastFiredAt
  default:                  after = cfg.CreatedAt

For the regressed case, `after = Mon 17:10 Beijing`, the next
enumeration window is `(Mon 17:10, Tue 12:30]`, and Tue 17:10 is
in the future — the hook returns nothing and the trigger waits
quietly for Tue 17:10 as the UI promised. For brand-new triggers
(last_fired_at NULL), the original `created_at` path still
applies. For long-dormant triggers the `replayWindow` cap remains.

Changes
-------
* `ListSchedulableAutopilotTriggers` SQL now returns
  `last_fired_at`.
* `autopilotTriggerConfig.LastFiredAt` is populated by the scope
  provider on every tick.
* `autopilotPlansForScope` cold-start branch uses the new anchor.

Tests
-----
* TestAutopilotScheduleJobColdStartHonorsLastFiredAt — seeds the
  exact dev-environment shape (created 3 days ago, last_fired_at
  5 hours ago, no sys_cron_executions row), runs a tick, asserts
  zero exec rows AND zero autopilot_run rows. Without the fix this
  test produces one of each at a historical plan_time.
* TestAutopilotScheduleJobColdStartBrandNewTriggerStillFires —
  asserts a brand-new trigger (last_fired_at NULL) still fires its
  first due occurrence on cold start.

All existing `TestAutopilotScheduleJob*` tests still pass.
