77ba0fdddb MUL-4009: hide not-configured Composio toolkits at Service layer (#4880)
* MUL-4009: hide not-configured Composio toolkits at Service layer

Filter out toolkits with no enabled auth config in Service.ListToolkits so
the Settings UI only shows connectable apps. A dead 'Not configured' card is
noise for end users, so drop the entry entirely instead of showing a greyed
label (which existed only to avoid a dead Connect button, MUL-3720).

- service.go: only append connectable toolkits; drop the connectable-first
  sort (all entries are connectable now); a resolver error now returns an
  error (502) instead of masking to an empty catalog, so the UI shows its
  honest load-failed state rather than a misleading 'no apps configured'.
- Keep the wire 'connectable' field (always true) for backward compat with
  older desktop clients that branch on it.
- composio-tab.tsx: remove the 'Not configured' branch; keep the
  toolkit.connectable guard as a client-side backstop.
- i18n: drop composio.not_connectable / not_connectable_hint from en/ja/ko/zh-Hans.
- Update service + handler tests to assert filtering and the resolver-error path.

* MUL-4009: address review — empty-state copy, 502 handler test, stale comments

Review follow-up on #4880:
- i18n: rewrite composio.page_description / empty_title / empty_description in
  all 4 locales. The empty state now means 'no toolkit with an enabled auth
  config in the project', not 'Composio returned no catalog' — the old copy
  misled users after filtering landed.
- Add TestComposio_ListToolkits_ResolverErrorIs502: fakes an auth-config
  resolver error and asserts ListComposioToolkits returns 502, pinning the
  no-silent-empty-catalog behavior (composioFakeSDK gains listAuthErr).
- Refresh stale 'full catalog / false connectable' docs in
  packages/core/types/composio.ts, composio/queries.ts, api/client.ts to the
  connectable-only model.

* feat(composio): server-side connect flow + connections REST (Notion MVP) (MUL-3720) (#4608)

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

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

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

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

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

Address PR 4608 review (CHANGES_REQUESTED):

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(composio): correct stale callback routing comments (MUL-3843)

The package header and ComposioCallback doc comments still described the
callback as sitting under the Auth middleware group. After the route was
moved out (this PR), update both to state it is a public route whose identity
comes from the signed state — addressing review nit from 张大彪.

* 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.

88377c1b1d fix(slack): recover attachment/blocks text for empty-Text chat messages (MUL-3931) (#4805)
* fix(slack): recover attachment/blocks text for empty-Text chat messages (MUL-3931)

`multica chat thread`/`chat history` dropped any message with an empty
top-level Text via normalizePage(), intended to skip join/system markers
but also discarding alerting/webhook bot roots (Grafana cards, incoming
webhooks) whose body lives in Attachments/Blocks. This regressed the
#4717 fix for its most common trigger: @mentioning the agent under an
alert card.

Add flattenSlackText(): fall back to Attachments[].Fallback, then
title/text/fields, then a best-effort Block Kit flatten (section/header/
context/markdown) before discarding. Derived text is capped so a verbose
card cannot flood the agent context; genuine content-less markers are
still dropped. Both read paths share normalizePage, so one fix covers
chat thread and chat history.

Closes #4803

* fix(slack): flatten rich_text blocks in chat history fallback (MUL-3931)

Addresses the review nit on #4805: flattenBlocks() previously handled
section/header/context/markdown but skipped rich_text, so a message
whose only body is a rich_text block (the shape Slack rich-text input
produces) could still be dropped. Walk rich_text sections/lists/quotes/
preformatted runs and concatenate their text and link runs.

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.

247e8ed5ab feat(slack): reuse account link across apps in one Slack workspace (#4786)
A Slack user who linked their Multica identity to one bot was re-prompted
to link again when messaging a second bot (a different Slack app) in the
SAME Slack workspace, because bindings are keyed per-installation
(installation_id, channel_user_id).

On an unbound inbound, the identity resolver now looks up an existing
binding for the same (Multica workspace, Slack team, Slack user) via the
new FindReusableChannelUserBinding query and, if that user is still a
workspace member, materializes a binding for the new installation instead
of returning ErrSenderUnbound — so the second bot resolves the user
silently. Reuse is fenced to one Multica workspace AND one Slack team, so
it never crosses either boundary; legacy installs with no recorded team
never reuse.

Adds resolver unit tests for every decision path and updates the Slack
integration docs (en/zh/ja/ko).

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.

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.

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

* 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).

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.

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).

* 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).

* 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).

* 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.

93ed3dc131 fix(lark): use app URL for web links (MUL-3679)
Point Lark binding and issue-created links at the web app URL (MULTICA_APP_URL)
instead of the backend public URL, so users on split-domain / self-host
deployments get working links. appURLFromEnv falls back to FRONTEND_ORIGIN,
matching the backend's existing app-URL resolution.

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.

c3d8529ba5 fix(channel): eliminate WaitGroup Add/Wait data race in engine.Supervisor (MUL-3620) (#4517)
The race detector caught a flaky failure on main (passes on retry):
Supervisor.startSupervisor does s.wg.Add(1) under s.mu, while Supervisor.Wait
calls s.wg.Wait() with no lock. Calling WaitGroup.Add concurrently with
WaitGroup.Wait is a data race and undefined per the WaitGroup contract — so it
only trips occasionally (it passed locally and in PR CI).

Wait now blocks on stopChan (closed by Run's defer when Run returns) before
calling wg.Wait(). Run is the sole caller of startSupervisor, so once Run has
returned no further Add can happen and wg.Wait is race-free. WaitWithTimeout
inherits the fix (it calls Wait), and its timer still bounds shutdown.

This latent race existed in the original lark.Hub.Wait too; fixed properly in
the generalized Supervisor.

Verified: go test -race -count=300 on the flagged test and -count=8 on the
whole engine package, all clean; no deadlock from the stopChan gate (every
caller pairs Wait with a started Run + cancelled ctx).

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.

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

* 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).

* 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.

ce28d0aa0e feat(integrations): add platform-agnostic channel foundation (MUL-3515) (#4412)
* feat(integrations): add platform-agnostic channel foundation

Introduce server/internal/integrations/channel — the contract every
inbound IM integration implements, so the core never learns a platform's
event JSON. Four pieces:

- Channel interface (Type/Connect/Disconnect/Send/Capabilities) + Factory
  + Config (channel_type + opaque JSON blob, maps to channel_installation).
- Normalized InboundMessage/OutboundMessage envelopes + Source/MediaRef/
  ReplyCtx/MsgType/ChatType. Envelope holds only cross-platform-true
  fields; platform specifics live in Raw, read only by the adapter.
- Capability bitmask: declaration only, no degrade logic in core.
- Registry: Type->Factory map, last-writer-wins, concurrency-safe.

Pure package (no DB/network/platform deps). Foundation for MUL-3515; the
lark cutover + lark_*->channel_* generalization land in follow-up PRs.

MUL-3515

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

* feat(channel): generalize lark_* tables into channel_* (DB layer)

Migration 123 creates channel_installation / channel_user_binding /
channel_chat_session_binding / channel_inbound_message_dedup /
channel_inbound_audit / channel_outbound_card_message /
channel_binding_token. Each carries a channel_type discriminator and a
JSONB config for platform-specific identifiers/credentials; cross-platform
columns stay flat. Existing Feishu rows are backfilled (channel_type=
'feishu', app_secret_encrypted via base64). NO foreign keys / cascades
(MUL-3515 §4) — integrity moves to the app layer in the cutover.

queries/channel.sql ports the lark query surface to channel_*, JSONB-aware,
plus DeleteChannelUserBindingsByWorkspaceMember /
DeleteChannelChatSessionBindingBySession for the app-layer cleanup that
replaces the removed cascades.

lark_* tables/queries are left in place here and removed once the Go
cutover lands, so this commit ships green on its own.

Verified: sqlc generate, go build ./..., full migrate chain (1..123) on
Postgres 17, and a real-data backfill spot-check (base64 round-trip,
NULL-strip, functional unique index on (channel_type, app_id)).

MUL-3515

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

* fix(channel): name app_id query param + multi-IM install key + null-safe binding merge

Addresses review on MUL-3515 (PR #4412):

- GetChannelInstallationByAppID: explicitly name params and cast app_id to
  ::text so sqlc emits AppID string. A bare $2 next to `config ->> 'app_id'`
  was mis-attributed to the JSONB config column, generating Config []byte.

- channel_installation uniqueness -> (workspace_id, agent_id, channel_type),
  with the UpsertChannelInstallation conflict key matched. Lets one agent
  hold one installation per IM (feishu + slack + ...) instead of a later
  install clobbering an earlier one. Behaviorally identical in the current
  feishu-only world; "one agent, at most one IM overall" stays an app-layer
  rule per MUL-3515 §4, not a DB constraint.

- CreateChannelUserBinding merges jsonb_strip_nulls(EXCLUDED.config) so a
  re-bind carrying {"union_id": null} no longer erases an already-captured
  union_id, restoring the old COALESCE(EXCLUDED.union_id, ...) semantics.

Regenerated with sqlc v1.31.1. Verified on PG17: re-install replaces in
place, feishu+slack coexist, null re-bind keeps union_id, real union_id wins.

* feat(lark): channel-backed Feishu store + fix base64 backfill wrapping

Cutover step 1 of switching the lark Go code from lark_* onto the channel_*
tables (MUL-3515). Introduces the JSONB config boundary the rest of the
cutover sits on, and fixes a latent backfill bug surfaced while building it.

- migration 123: strip newlines from the app_secret_encrypted base64 backfill.
  PostgreSQL encode(...,'base64') MIME-wraps at 76 chars, and a secretbox-
  sealed ~72-byte secret exceeds that. Go's encoding/json decodes a JSON
  string into []byte with base64.StdEncoding, which rejects embedded newlines,
  so without the strip every migrated installation would fail to decrypt its
  app secret once reads move to channel_installation.config.

- store.go: flat domain types (Installation / UserBinding / ChatSessionBinding)
  with field parity to the retired db.Lark* rows, plus the feishu config codec.
  Row->domain mappers decode the JSONB config; the secret decoder is
  whitespace-tolerant so legacy MIME-wrapped data still round-trips, while the
  encoder emits unwrapped base64. Binding config encodes an absent union_id as
  "{}" so the upsert's jsonb_strip_nulls merge never clobbers a stored union_id.

- store_test.go: 72-byte secret round-trip, MIME-wrapped tolerance, optional
  null-strip, and flat-column preservation. Verified on PG17.

Field parity keeps the upcoming ~190 db.LarkInstallation call sites a
mechanical rename. No call sites switched yet; behavior unchanged.

* feat(lark): route inbound integration onto channel_* + explicit membership checks

Cutover step 2 (MUL-3515): switch the Feishu Go code from the lark_* queries to
channel_* via a ChannelStore adapter, and replace the removed member foreign key
with explicit application-layer membership checks. No user-visible behavior change.

- channel_store.go: ChannelStore embeds *db.Queries and SHADOWS the ~24 lark
  query methods with channel_*-backed equivalents, keeping the db.Lark*
  signatures so the dispatcher/hub/services and their ~20k lines of tests stay
  untouched; the feishu JSONB config is (de)coded by store.go. Adds
  IsWorkspaceMember and a tx-aware WithTx. Only production wiring swaps
  *db.Queries for *ChannelStore.

- Membership re-check (§4 removed the lark_user_binding -> member FK, so a
  binding row no longer proves current membership):
  * the dispatcher inbound identity step verifies membership after the binding
    lookup; a former member's stale binding is dropped as non_workspace_member
    + audited and never reaches chat_session (§4.3 safety property).
  * RedeemAndBind and BindInstallerTx replace the now-dead FK (23503) branch
    with an explicit IsWorkspaceMember gate, preserving the existing
    ErrBindingNotWorkspaceMember outcome without burning the token.

- router wires the ChannelStore into the patcher, typing indicator, dispatcher,
  hub, and the union_id/region backfills; constructor-based services wrap
  *db.Queries internally so their signatures and nil-check tests are unchanged.

Verified: go build ./... ; go vet ; gofmt ; go test -race ./internal/integrations/...
(full lark suite green unchanged + new membership drop/error tests). Adapter
field mappings (secret base64, union_id RMW, chat-id/open-id remaps, dedup,
token, card) checked end-to-end against a PG17 channel_* schema.

lark_* tables and queries remain (unused at runtime) until the S3 cleanup-hooks
and S4 drop-tables/rename commits.

* fix(channel): renumber generalization migration 123 -> 124

main merged 123_issue_stage after this branch forked, so the branch's 123_channel_generalization now collides on the migration number. The runner keys schema_migrations by full version string and would still apply both, but a duplicate number is a merge hazard and convention violation, so move the channel migration to the next free slot (124).

issue_stage (ALTER issue ADD COLUMN stage) and the channel generalization touch disjoint tables; verified on PG17 that 123_issue_stage applies cleanly on a DB already carrying 124_channel_generalization, so the two are order-independent. sqlc regenerated (v1.31.1): only the migration-number comment changed.

* feat(channel): prune channel bindings on member removal + chat session delete

MUL-3515 §4 dropped every channel_* foreign key, so the old ON DELETE CASCADE that cleared a user's channel_user_binding when they left a workspace, and a chat's channel_chat_session_binding when its chat_session was deleted, no longer fires. Re-establish that integrity in the application layer, inside the existing transactions: revokeAndRemoveMember -> DeleteChannelUserBindingsByWorkspaceMember, DeleteChatSession -> DeleteChannelChatSessionBindingBySession.

Adds real-DB tests for both paths, including a scoping check that a remaining member's binding survives the prune. Verified on PG17: both new tests plus the existing revocation tests and the full handler package pass.

* fix(channel): scope Lark/Feishu store reads to channel_type='feishu'

The S2 cutover routed the Feishu integration onto channel_*, but the Lark-facing ChannelStore wrappers read installation / chat-session-binding / outbound-card rows across ALL channel_type values. Once a second IM exists, that would let the Lark hub supervise a non-Feishu installation, the Lark install list show it, /lark/installations/{id} revoke another channel's row, and the outbound patcher / typing indicator act on a non-Feishu chat binding or card.

Add a channel_type predicate to the six read/list channel queries and pass channelTypeFeishu from every wrapper: GetChannelInstallation, GetChannelInstallationInWorkspace, ListChannelInstallationsByWorkspace, ListActiveChannelInstallations, GetChannelChatSessionBindingBySession, GetChannelOutboundCardByTask.

The S3 cleanup deletes (DeleteChannelUserBindingsByWorkspaceMember / DeleteChannelChatSessionBindingBySession) stay all-channel on purpose: a member leaving or a chat_session being deleted should clear every IM's binding. Adds a real-DB test that seeds a Slack installation/binding/card next to the Feishu ones and asserts the Lark wrappers never return them.

* refactor(channel): replace db.Lark* translation layer with lark domain types

S2 introduced ChannelStore as a translation layer that read/wrote channel_* but kept the retired db.Lark* struct/param shapes so the dispatcher/hub/services and their ~20k lines of tests did not have to change. This collapses that layer: the store now takes and returns the package's flat domain types (Installation, UserBinding, ChatSessionBinding, InboundMessageDedup, BindingTokenRow, OutboundCardMessage) and the *Params types in params.go, with channel-neutral field names (ChannelUserID / ChannelChatID / ...). All call sites, fakes, and tests move to the domain types.

No behavior change: only channel_* is read/written (as before); db.Lark* is now unused, and the lark_* tables + queries/lark.sql are removed in the next commit. Verified on PG17: go build / vet / gofmt clean, go test -race ./internal/integrations/... green (the ~20k-line fake suite), and the lark + handler suites pass.

* refactor(channel): drop lark_* tables and queries (remove old path)

The Go cutover (previous commit) moved the lark package entirely onto channel_* and the domain types, leaving the lark_* tables, queries/lark.sql, and the generated db.Lark* models unused. Remove them per the design (§5: replace, do not keep both): migration 125 drops the seven lark_* tables (data already lives in channel_* since migration 124), and queries/lark.sql is deleted + sqlc regenerated, removing the db.Lark* models and lark query methods.

The 125 down recreates the authoritative pre-drop schema (bot_union_id, region, per-installation dedup PK, thread-reply columns). Verified on PG17: fresh migrate up ends with lark_* gone + channel_* present; isolated 125 down/up round-trips correctly; go build / vet / gofmt clean; go test -race ./internal/integrations/... and the handler suite pass.

* refactor(channel): defer lark_* table drop to a follow-up migration

Preflight deploy review: dropping lark_* in the same release that cuts over (old migration 125) is not rollback/rolling-safe — the v0.3.27 release still reads lark_*, so a rolling deploy or a post-deploy code rollback would hit "relation does not exist". Remove the drop and keep the old tables for one release (standard expand/contract): migration 124 already backfilled lark_* -> channel_*, the new code reads/writes only channel_*, and the physical drop moves to a separate cleanup migration once this ships and is observed.

The lark_* tables remain in the schema, so sqlc regenerates the (now unused) db.Lark* models; queries/lark.sql stays deleted (the new code uses channel_*). No code path reads lark_* — only the destructive drop is deferred, keeping the design's no-compat-layer / no-dual-write rule while being deploy-safe.

* fix(channel): skip orphaned installations in hub-boot active scan

Preflight deploy review: channel_installation dropped the workspace/agent FK (MUL-3515 §4), so unlike lark_installation it does not cascade away when its workspace is deleted or its agent is hard-deleted (e.g. runtime teardown). The hub-boot query then keeps opening a WebSocket for a bot whose owner is gone.

JOIN ListActiveChannelInstallations to live workspace + agent so an orphaned installation is never connected, uniformly for every deletion path. The JOIN matches the old ON DELETE CASCADE semantics (row existence, not agent archival), so an archived-but-present agent's installation is still listed; the orphaned row's encrypted secret is thereby never decrypted/used.

Tests: a real-DB handler test asserts a deleted-workspace/agent installation and a non-Feishu one are both excluded; the lark scope test's active-list assertion moved there since the JOIN now needs real workspace/agent fixtures. (Physically deleting dormant orphaned channel rows on workspace/agent deletion is a separate app-layer-cleanup follow-up.)

* docs(channel): document non-rolling cutover constraint for the lark->channel migration

Elon deploy review: keeping the lark_* tables (deferred drop) stops old v0.3.27 code from crashing, but is not full expand/contract. Migration 124 is a one-time backfill; afterwards new code runs on channel_* (lease + dedup on channel_*) while pre-cutover code runs on lark_* (lease + dedup on lark_*). If both run concurrently during a rolling deploy, each side claims the same Feishu bot's WS lease on its own table and double-processes inbound events.

This release therefore requires a NON-ROLLING cutover (stop the old hub before applying migration 124 + starting new code; rollback is not lossless once new code writes channel_*). Documented where deployers/reviewers see it: migration 124 header gains a ROLLOUT note; the channel_store.go header is corrected (lark_* tables are retained one release for rollback safety, not "gone"; the store still never touches them). Comment-only — no schema/codegen/behavior change.

* feat(lark): add MULTICA_LARK_HUB_DISABLED switch for the channel cutover

The lark_*->channel_* cutover needs a way to make the Feishu bot briefly unavailable WITHOUT taking down the whole multica-api process — the Lark hub is a goroutine inside it, not a separate Deployment. MULTICA_LARK_HUB_DISABLED=true parks the hub at startup: the API serves HTTP normally but never claims a WS lease or opens a Feishu connection.

Rollout (see migration 124 ROLLOUT note): ship the new release with the flag SET so new pods run API-only while old pods (hub on lark_*) drain during the rolling deploy — the two hubs never overlap. After the old pods are gone and migration 124 has run, flip the flag off; the new hub comes up on channel_*. The old backend does NOT need this switch — its hub stops when k8s terminates the old pods, not via a flag. Nil-ing LarkHub reuses the existing not-configured path so both the startup start and the shutdown join skip it.

* docs(channel): point migration 124 ROLLOUT note at the hub-disable switch

Refine the rollout note to use MULTICA_LARK_HUB_DISABLED for a bot-only cutover (new pods serve API with the hub parked while old pods drain; flip the switch off after the migration), instead of the earlier whole-API recreate. Comment-only.

* docs(channel): fix migration 124 rollout order and document self-host cutover

The previous ROLLOUT note shipped the new (channel_*) build before
running migration 124, so the channel_*-backed HTTP paths (installation
list/install/revoke, chat-session delete, member revoke) would 500 in
the window between new-pod boot and the deferred migration. Restate the
runbook around two explicit invariants — channel_* must exist before the
new build serves those paths, and the old/new hubs must never overlap —
and order the steps so channel_* is created first (park old hub -> snapshot
-> deploy parked new build -> unpark). Document that default self-host
(entrypoint migrate + single-replica Recreate) satisfies both invariants
automatically and needs no manual steps; only prd / multi-replica rolling
self-host needs the switch procedure. Clarify in main.go that the
hub-park switch is generation-agnostic (parks whichever hub the build
carries), which is what enables the preparatory release.

0aa3b53c25 MUL-3378 feat(lark): reply inside the originating thread (话题) instead of the group (#4262)
* feat(lark): reply inside the originating thread (话题) instead of the group

When a user @-mentions the bot inside a Lark topic/thread, the bot now
replies back into that thread rather than posting a fresh message at the
chat level. Behavior is automatic and scoped: only triggers that were
themselves inside a thread get a threaded reply, so normal group/p2p
chats are unchanged.

The outbound path is event-driven and decoupled from the inbound
message, so the trigger message_id + thread_id are persisted on
lark_chat_session_binding (migration 122) at ingest time. The patcher
then routes the agent reply (text / markdown card / error card) and the
OutcomeReplier notices (/issue confirmation, offline/archived) through
Lark's reply endpoint with reply_in_thread=true when a thread is present,
falling back to a chat-level send if the threaded reply fails.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(lark): classify thread-reply failures before chat-level fallback

Only retry a threaded reply at the chat level when Lark returns an
explicit "this message/topic cannot receive a threaded reply" error
(recalled trigger, topic gone, topics disabled, aggregated message,
etc.). Transport errors, 5xx, timeouts, rate limits, and ambiguous
failures are now logged and returned as failures instead of being
retried, so we never duplicate a reply or leak a thread-only reply
into the main group chat.

The three reply-capable send methods now return a structured *APIError
carrying the Lark business code, and isThreadReplyUnsupported drives
the fallback via an allowlist. sendWithThreadFallback is promoted to a
package-level function so the immediate OutcomeReplier sends (/issue
confirmation, offline/archived notices) share the same classified
fallback path instead of silently swallowing thread-reply failures.

24b162cdbc feat(daemon): surface the real task initiator to the agent runtime (MUL-2645) (#3899)
* feat(daemon): surface the real task initiator to the agent runtime (MUL-2645)

In a multi-person workspace the agent runtime only ever saw the runtime
OWNER identity: the brief's `## Requesting User` is sourced from
runtime.OwnerID and the task-scoped token is owner-bound, so every
requester (whoever commented, @mentioned, or chatted) appeared to the
agent as the owner. Agents that route by initiator for permission,
privacy, or audit all misjudged.

Resolve the real task initiator at claim time and surface it distinctly
from the owner:
- comment / mention trigger -> triggering comment's author (member or agent)
- chat task -> chat session creator (sessions are creator-only)
- on-assign / autopilot / quick-create -> no attributable initiator (omitted)

Adds initiator_{type,id,name,email} to the claim response, the daemon
Task, and TaskContextForEnv, rendered into the brief as a new
`## Task Initiator` section. The section documents the privacy boundary:
the agent's credentials stay owner-scoped, so this is an attested
identity for the agent's own routing/privacy logic, not act-as. No DB
migration — both paths are derivable from existing rows.

Tests: brief rendering (member/agent/omit/sanitize) + email guard unit
tests, and claim-handler tests for the comment and chat paths.

* fix(chat): store real sender as task initiator, not chat_session creator (MUL-2645)

Review fix (Niko, PR #3899). v1 resolved the chat task initiator from
chat_session.creator_id at claim time. That is correct for web chat and
Lark p2p (creator == sender), but WRONG for Lark group chats: the group
session creator is deliberately the installer (stable identity across
member churn), not the message sender. So in a Lark group, every member
who triggered the agent showed up in the brief as the installer/owner —
the exact bug this issue is about, still live at that entry point.

Capture the real sender at enqueue time instead of deriving it from the
session creator at claim time:

- migration 117: agent_task_queue.initiator_user_id (FK user, ON DELETE
  SET NULL); NULL for non-chat and pre-migration rows.
- EnqueueChatTask now takes an explicit initiatorUserID. Web chat passes
  the authenticated request user; the Lark dispatcher threads the inbound
  sender (binding.MulticaUserID) through scheduleRun -> flushChatRun. The
  debouncer keeps the latest scheduled flush per session, so in a multi-
  sender silence window the LATEST sender wins (documented + tested).
- claim handler resolves the initiator from task.initiator_user_id and
  drops the creator_id fallback entirely.

The Lark group session creator stays the installer (unchanged) — only the
task initiator is corrected, keeping the two concepts cleanly separate.

Tests: dispatcher group regression (initiator = sender, not installer),
latest-sender-wins, p2p initiator assertion; the chat claim handler test
now sets creator != initiator and asserts the stored sender wins.

f8bd1d8fc2 feat(lark): show real speaker names in Feishu group context (MUL-3084) (#3828)
* feat(lark): resolve real speaker names in group context (MUL-3084)

The recent-context block (and quoted/forwarded blocks) labeled senders
positionally as "User 1 / User 2", and the agent had no idea who had
@-mentioned it. Add APIClient.BatchGetUsers (contact/v3/users/batch) and,
on the group prefetch path, resolve the surrounding speakers AND the
trigger sender to display names in one batch call. Speakers now render as
"[Alice]: ..." and the user's own message as "[Charlie]: ..." so the
agent knows who addressed it. Unresolved senders (restricted contact
scope, deactivated user) fall back to positional "User N"; resolution is
best-effort and never blocks ingestion. Closes the standing speaker-name
TODO in the enricher.

* fix(lark): resolve names for quoted/forwarded senders too (review)

Address the #3828 review: BatchGetUsers only included the recent-window
and trigger senders, so a quoted parent / merge_forward child whose
sender was NOT in the recent window still rendered as "User N".

Restructure Enrich into fetch (Phase 1) -> resolve names (Phase 2) ->
render (Phase 3): quote/forward items are now fetched up front and their
senders folded into the single Contact batch, so every block (recent +
quoted + forwarded) shows real names in group chats. p2p keeps positional
labels. Replaces the fetch+render renderQuoted/renderForwarded with a
render-only renderQuotedBlock plus an inline forward fetch.

05e38e5d37 feat(lark): split bind CTA into Feishu and Lark entry points (MUL-3083) (#3832)
* feat(lark): split bind CTA into Feishu and Lark entry points (MUL-3083 follow-up)

The single "Bind to Lark" button began the device flow against
accounts.feishu.cn and relied on a mid-poll tenant_brand="lark" to
auto-switch international users over to accounts.larksuite.com. Lark
users had to scan a QR served from a Feishu domain first, which
surfaced as confusing in real use.

Replace with two explicit CTAs side by side — "Bind to Feishu" and
"Bind to Lark" — and route the device-flow begin straight to the
matching accounts host based on the user's choice. The mid-poll
auto-switch is preserved as a safety net for users who pick the wrong
entry.

Backend
- RegistrationClient.Begin(ctx, namePreset, region): POSTs to
  c.cfg.LarkDomain when region=lark, c.cfg.Domain otherwise. Empty /
  unknown region falls back to Feishu (matches RegionOrDefault).
- BeginInstallParams.Region threads through to the registration session
  and onto runPolling's initial region local. SwitchedDomain still
  flips it on tenant_brand=lark.
- POST /api/workspaces/{id}/lark/install/begin accepts ?region=feishu|lark
  with empty defaulting to feishu for back-compat.

Frontend
- api.beginLarkInstall(wsId, agentId, region) — region now required
  so every call site is forced to pick a cloud explicitly.
- LarkAgentBindButton renders two buttons; dialog state collapsed into
  a single dialogRegion useState so an "open but with no region picked"
  intermediate state can't exist.
- LarkInstallDialog takes region as a required prop and renders
  region-aware copy (title, description, scan hint, link fallback,
  success toast).

i18n
- Add bind_button_{feishu,lark}, install_dialog_{title,description}_*,
  install_scan_hint_*, install_open_link_fallback_*, and
  install_success_toast_* keys across en, zh-Hans, ja, ko. Legacy
  single-region keys are kept for now; nothing in the tree references
  them anymore but a follow-up cleanup can remove them once the dust
  settles.

Tests
- Two new lark.RegistrationClient tests pin region routing in both
  directions (region=lark hits LarkDomain; region=feishu hits Domain).
- Two new lark-tab.test.tsx cases pin that clicking each CTA calls
  beginLarkInstall with the matching region argument. Existing CTA
  tests updated to expect both buttons in place of one.

* fix(lark): bidirectional tenant_brand swap + region-aware badge + link context menu

Addresses Elon's review on PR #3832 plus a separate report that the
"Or tap here to open in Lark" link in the install dialog had no
standard right-click affordances on the desktop app.

Backend (must-fix from review)

The PR's stated 'safety net for users who pick the wrong CTA' only
worked one direction: a Feishu-first begin already swapped to Lark on
tenant_brand=lark, but the new Lark-first begin (added by this same PR)
had no reverse path — a user who picked 'Bind to Lark' but actually
authorized with a Feishu account would carry RegionLark all the way
through finishSuccess and either fail at GetBotInfo or commit a
wrong-region row.

- PollResult now carries SwitchedDomain AND SwitchedRegion in
  lockstep, so the caller never has to re-derive region from the
  domain string.
- Poll() detects tenant_brand=feishu while polling against a non-Feishu
  host symmetrically with the existing tenant_brand=lark check, gated
  on the current host so we don't loop on a brand we already match.
- runPolling reads region from res.SwitchedRegion instead of the
  hardcoded RegionLark — the SwitchedDomain branch now flips both
  feishu→lark and lark→feishu cleanly.
- Tests: updated the existing TestRegistrationClient_Poll_DomainSwitchOnLarkTenant
  to assert SwitchedRegion, added TestRegistrationClient_Poll_DomainSwitchOnFeishuTenant
  for the reverse, and TestRegistrationClient_Poll_NoSwitchWhenAlreadyOnMatchingHost
  (table-driven, both directions) to pin that the gate doesn't loop.

Backend (nit from review)

Handler comment on /lark/install/begin claimed unknown region defaults
to Feishu downstream, but the handler already returns 400 on unknown
values. Updated the comment to match the actual behavior and document
why we 400 rather than silently normalize (so a frontend typo can't
land users on the wrong cloud without telling them).

Frontend (nit from review)

The Agent inspector's Connected badge was hardcoded 'Connected to
Lark' / 'Manage in Lark' (en) and 'Connected to Feishu' / 'Manage in
Feishu' (zh-Hans) — both wrong half the time now that the install
flow can land on either cloud per agent. Made the badge text and
Manage tooltip read from installation.region:

- agent_bot_connected_label_{feishu,lark}
- agent_bot_manage_link_{feishu,lark}
- agent_bot_manage_tooltip_{feishu,lark}

across en / zh-Hans / ja / ko. Legacy single-region keys retained for
safety. Existing badge tests updated: fixtures without 'region' now
expect the Feishu copy; the region: 'lark' test was promoted to also
assert the Lark badge text and link target. 21/21 lark-tab tests pass.

Desktop (separate report)

Right-clicking an <a> in the renderer surfaced only Copy / Cut /
Paste / Select All — no 'Open Link in Browser' or 'Copy Link Address'.
The renderer's <a target="_blank"> click path already routes through
setWindowOpenHandler → openExternalSafely, but discoverability via the
context menu was missing.

context-menu.ts now appends two link-specific items when params.linkURL
is an http(s) URL. Open Link routes through openExternalSafely (reuses
the existing scheme allowlist); Copy Link Address writes to Electron's
clipboard. Labels are localized to the OS preferred language for the
four locales the renderer ships (en / zh-Hans / ja / ko); zh-* variants
all route to zh-Hans, anything else falls back to English. New
context-menu.test.ts pins five cases: link items show for http(s),
not for javascript:/mailto:/etc., not when no link is under the cursor,
zh-CN gets Chinese, fr-FR falls back to English. 198/198 desktop tests
pass.

6d0b9e3918 feat(lark): prefetch surrounding group context on @-mention (MUL-3084) (#3819)
* feat(lark): prefetch surrounding group context on @-mention (MUL-3084)

In Feishu group chats the Bot only saw the single message that @-mentioned
it — never the surrounding conversation — because the inbound enricher only
inlined context the user explicitly attached (a quoted reply or a
merge_forward), and the API client had no way to list a chat's history.

Add APIClient.ListChatMessages (GET /open-apis/im/v1/messages,
container_id_type=chat, ByCreateTimeDesc, page_size clamped to Lark's 50
cap) and, for a group message addressed to the Bot, prefetch a bounded
window of recent messages and inline them as a <recent_context> block
ahead of the user's own message. The trigger and any quoted parent are
excluded so nothing is duplicated; speakers are labeled positionally
(User 1/2 / Bot); failures degrade to a visible placeholder and never
block ingestion. Window size is configurable via
InboundEnricherConfig.RecentContextSize (<=0 disables); production wires
DefaultRecentContextSize (20). One list call per addressed turn keeps the
fetch within the inbound ACK / EnrichTimeout budget.

* feat(lark): anchor group context window to trigger time, default 10

Address review feedback on MUL-3084:
- Anchor the recent-context prefetch to the trigger message's time:
  thread the message create_time through InboundMessage and pass it as
  the list end_time (millis -> seconds), so the window is the
  conversation up to the @-mention rather than whatever is newest when
  the slightly-later prefetch HTTP call runs. end_time is omitted when
  the time is missing/unparseable (falls back to newest N).
- Lower DefaultRecentContextSize from 20 to 10.

* fix(lark): region-aware doJSON for ListChatMessages after rebase

origin/main merged #3815 (Lark dual-region support), which changed
doJSON to take a per-call baseURL resolved via resolveBaseURL(creds).
Adapt the new ListChatMessages call to that signature so the backend
build passes against latest main, and refresh the now-stale
ListMessagesParams comment (EndTime is exposed).

6ac8314711 feat(lark): support both Feishu and Lark from one deployment (MUL-3083) (#3815)
* feat(lark): serve Feishu and Lark from one deployment, per installation

The Lark integration was locked to a single open-platform host chosen
deployment-wide (MULTICA_LARK_HTTP_BASE_URL / _CALLBACK_BASE_URL,
defaulting to open.feishu.cn), so one deployment could talk to only the
mainland Feishu cloud OR Lark international — never both. Teams on the
other tenant could not use the integration at all.

Make the host per-installation. The device-flow installer already
auto-detects the tenant (Lark emits tenant_brand="lark" mid-poll); we now
persist that as lark_installation.region, carry it on
InstallationCredentials.Region, and resolve the open-platform host per
call (REST + WS bootstrap) from the region. An explicit cfg.BaseURL
(env / httptest) still overrides every region, so existing tests and
staging/proxy setups keep working.

- migration 116: lark_installation.region TEXT NOT NULL DEFAULT 'feishu'
  CHECK (region IN ('feishu','lark')) — existing rows are all mainland.
- lark.Region enum + OpenPlatformBaseURL/RegionOrDefault helpers.
- registration: thread the detected region into finishSuccess so the
  install-time GetBotInfo hits the right cloud AND the row records it.
- every credential-build site (patcher, replier, WS provider, union_id
  backfill) copies region off the installation row.
- region is part of the WS supervisor fingerprint so a re-install that
  switches cloud restarts the connection.
- API: surface region on the installation listing DTO.

* feat(lark): surface installation region in settings UI

Read the per-installation region off the listings response: build the
"Manage in Lark" dev-console host from it (open.feishu.cn vs
open.larksuite.com instead of a hardcoded mainland host) and render a
Feishu / Lark badge on each connected bot. The field is optional and
defaults to Feishu when an older server omits it (API-compat). Adds the
region_feishu / region_lark labels to all four locales.

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

* docs(lark): document simultaneous Feishu + Lark support

The cloud each bot belongs to is now auto-detected at install and stored
per installation, so one deployment serves both. Replace the old
"point MULTICA_LARK_HTTP_BASE_URL at larksuite for international tenants"
guidance (now just an optional override) in all four locales.

* fix(lark): repair legacy Lark-international installs on upgrade

Review follow-up (MUL-3083). Migration 116 backfilled every existing
lark_installation to region='feishu', assuming all historical rows were
mainland. But self-host deployments could already run Lark international
via the deployment-wide MULTICA_LARK_HTTP_BASE_URL override, so those
rows are really Lark — clearing the override after upgrade (which the new
docs invite) would route them to open.feishu.cn and break them.

Add a one-shot startup repair, BackfillRegionFromLegacyOverride, fired
off the hot path like BackfillBotUnionIDs: when the deployment's global
base-URL override targets open.larksuite.com, relabel the still-default
'feishu' rows to 'lark'. Gating on the deployment-wide override is what
makes it safe — every pre-existing install on such a deployment was Lark.
Idempotent; no-op on mainland / fresh deployments. Verified end-to-end
against a scratch DB (flip then 0-row idempotent re-run).

Also document that a Lark/飞书 app_id is globally unique across both
clouds, which is what makes the app_id-keyed token cache and the
UNIQUE(app_id) constraint safe across regions (review nit).

MUL-3083

* docs(lark): fix ops guidance to match auto per-installation region

Review follow-up (MUL-3083). .env.example and docker-compose.selfhost.yml
still told operators that international Lark requires pointing both base
URLs at open.larksuite.com — now wrong, and it would push a fresh
deployment back into a single-cloud override. Rewrite them: the base
URLs are optional deployment-wide overrides; normal dual-cloud operation
keeps them empty. Document the first-boot auto-relabel for deployments
migrating off the old single-cloud override, across the integration docs
(en/zh/ja/ko).

f3ab29cdfc fix(lark): publish lark_installation:created at row-commit, not on status poll (#3770)
The agent Integrations tab's "已连接到飞书" connection badge only updated after
a manual page refresh. lark_installation:created had a single emit site — the
status-poll handler GetLarkInstallStatus — so it only fired while a browser was
actively polling the install dialog to success. Every other surface (a second
admin, the inspector sidebar, the Settings panel, or the installer whose dialog
closed before the success poll) never received the invalidation frame, and under
the QueryClient defaults (staleTime: Infinity) the installations cache stayed
stale until a full page refresh.

Publish the event from RegistrationService.finishSuccess at the row-commit point,
mirroring the already-correct revoke path, so every workspace client refreshes
the moment the install lands. Wire the bus via an optional SetEventBus (keeps the
constructor and its validation tests untouched, nil-safe) and remove the now-
redundant poll-handler emit.

6e004149a8 feat(lark): debounce inbound run trigger per chat session (MUL-2968) (#3742)
A forwarded transcript plus a follow-up note arrive as two separate Lark
messages, each of which synchronously called EnqueueChatTask — so the bot
ran twice (once on the bare forward, before the note arrived). The chat
task already reads the whole session history at run time, so the messages
never needed stitching; only the run TRIGGER did.

Introduce pendingBatcher: a per-chat_session debouncer that collapses a
burst into one agent run on a 3s silence window. Each message is still
appended, deduped, and ACKed synchronously and individually; step 8 of the
dispatcher now schedules a debounced flush instead of enqueuing inline.

Because EnqueueChatTask's agent-offline / agent-archived verdict is now
only known at flush, the dispatcher emits that notice itself via an
injected FlushReply (wired to OutcomeReplier.Reply) rather than returning
it synchronously to the hub. Infra failures are logged, not surfaced — the
inbound frame was ACKed long ago. The hub drains the batcher on graceful
shutdown so a normal restart does not drop a pending window.

Out of scope (owner-aligned): group-chat multi-speaker batching, restart
recovery for the in-process window, and forwarded-sender real-name
resolution.

5eba94ee25 feat(lark): inbound context enrichment — post / merge_forward / quoted-reply (MUL-2951) (#3724)
Expand an inbound Lark bot message's body before dispatch with the context
a user explicitly attached, so the agent sees a semantically complete
conversation instead of a bare "@bot 总结一下".

- post: flatten rich-text (title + paragraphs, links, @-mentions) to plain
  text synchronously in the decoder.
- merge_forward: inline the forwarded transcript via a single GetMessage —
  GET /open-apis/im/v1/messages/{id} returns the forward sentinel plus the
  bundled children. (The issue's container_id_type=merge_forward query is
  undocumented; this avoids it and also handles a forwarded quoted parent.)
- quoted reply: prepend the parent_id message as a <quoted_message> block;
  a parent that is itself a forward nests a <forwarded_messages> block.
- new InboundEnricher runs in the WS connector between decode and emit,
  bounded by EnrichTimeout and degrading to "[unable to fetch]" placeholders
  so it never blocks the ~3s long-conn ACK budget.

/issue stays parseable on a quote-reply by parsing the command from the
user's own text (CommandBody) rather than the enriched body.

Short-window debounce batching (issue item #4) is tracked as a follow-up.

8c98940b79 Lark Bot integration MVP: migration + service boundary (MUL-2671) (#3277)
* feat(db): add Lark integration migration (MUL-2671)

Introduces seven tables for the 飞书 Bot integration MVP — per-agent
PersonalAgent installations, user/chat bindings, inbound dedup +
non-content drop audit, outbound card mapping, and short-lived
single-use member binding tokens.

Schema notes:
- chat_session schema unchanged; Lark routes through a separate
  binding table rather than adding a metadata JSONB column.
- Outbound card mapping is task/message scoped so multiple runs on
  the same session can't stomp each other's cards.
- lark_inbound_audit stores routing / identity / drop_reason ONLY,
  never message body — the audit channel for unbound users and group
  messages that don't address the Bot.
- app_secret stores ciphertext (encryption helper lands in a follow-up
  commit on this branch); DB never sees plaintext.

* feat(util): add secretbox AES-256-GCM helper for at-rest secrets

First consumer is lark_installation.app_secret (MUL-2671 §4.4), but
the helper is intentionally generic — future per-tenant secrets that
must not appear in a DB dump can reuse it.

Construction: AES-256-GCM with a per-message random nonce, providing
authenticated encryption. Tampered ciphertext fails Open instead of
silently decrypting to garbage. Master key loaded from a base64 env
var via LoadKey; key rotation is not in scope yet.

* refactor(issues): extract IssueService.Create as single create entry (MUL-2671)

Establishes the service-layer boundary mandated by Elon's 二审 of
MUL-2671 §4.8: issue creation no longer lives inside the HTTP
handler. Both the HTTP POST /issues handler and the future Lark
/issue command call into service.IssueService.Create, so duplicate
guard, issue numbering, attachment linking, broadcast, analytics,
and agent/squad enqueue stay aligned.

Handler responsibilities shrink to parsing the HTTP request, doing
actor resolution / validation (transport-specific), and converting
service results into the IssueResponse + 201. The transaction-wrapped
core, attachment link, event publish, analytics capture, and
agent/squad enqueue all move into service.IssueService.Create.

A BroadcastPayload callback on the service keeps the WS broadcast
shape (the full IssueResponse) without forcing the service to
depend on handler-layer response types.

* feat(integrations): add Lark package skeleton (MUL-2671)

Establishes the architectural boundaries Elon's 二审 mandated as
first-PR blockers without dragging in OAuth, WebSocket, or
card-patching code (those land in follow-up PRs):

- ChatSessionService interface — channel-aware chat-session entry
  point for Lark, deliberately separate from the HTTP SendChatMessage
  handler. The HTTP handler's single-creator guard (creator_id ==
  request user_id) is correct for the browser client but rejects
  group chat_sessions by construction; Lark needs its own service.
- AuditLogger interface — the only path for recording dropped events.
  Its signature deliberately omits message body, enforcing the
  drop-audit policy (MUL-2671 §4.7) at the type level: unbound users
  and non-addressed group messages can't accidentally end up in
  chat_session.
- Typed IDs (OpenID, ChatID) prevent UUIDs from being conflated with
  Lark-side identifiers at compile time.
- DropReason constants align dashboard/audit queries across callers.

* refactor(issues): move parent/project workspace check into IssueService (MUL-2671)

Parent existence and project workspace membership now live inside
IssueService.Create, inside the same transaction as the duplicate guard
and counter increment. The HTTP handler stops re-implementing the
lookup; every future create entry (Lark /issue, MCP, API keys) inherits
the same boundary without copy-pasting the SQL.

Adds two error sentinels (ErrParentIssueNotFound, ErrProjectNotFound)
so transports can translate to their own error shapes. Handler-level
cross-workspace tests guard the boundary against future regressions.

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

* fix(db): harden Lark migration safety底座 — TTL cap + workspace FK (MUL-2671)

Two storage-layer hardenings that move the must-fix line off "the app
layer enforces it" and onto the schema itself, so future write paths or
hand-inserted rows cannot regress the invariants.

1) lark_binding_token TTL cap. The DB CHECK was 1 hour as
   defense-in-depth while the app constant was 15 minutes; the CHECK
   now matches the product cap (15 minutes). Application constant
   docstring updated to reflect that storage enforces the same bound.

2) lark_user_binding workspace membership. The table previously only
   FK'd to workspace / user / installation independently, so a binding
   could exist for a user no longer in the workspace, or claim a
   workspace different from its installation's. Two composite FKs
   close the gap structurally:

   * (installation_id, workspace_id) → lark_installation(id, workspace_id)
     — guarantees a binding's workspace_id always matches its
     installation's workspace_id. A new UNIQUE (id, workspace_id) on
     lark_installation is added as the FK target.

   * (workspace_id, multica_user_id) → member(workspace_id, user_id)
     with ON DELETE CASCADE — when a user is removed from the
     workspace, the binding cascades away in the same transaction.
     There is no longer a path where lark_user_binding outlives
     workspace membership.

These two FKs are the schema-level proof for §4.3's "unbound or
non-workspace members cannot leak content into chat_session" invariant.

* feat(integrations/lark): inbound services + /issue dispatcher (MUL-2671)

Lands the inbound service layer for the Lark Bot MVP, sitting on top
of the migration + service-boundary scaffold from the previous commits.
What ships:

- sqlc queries for all seven lark_* tables (idempotent dedup insert,
  CAS WS-lease, single-use binding-token consume, etc.) plus
  GetMostRecentUserChatMessage for the /issue fallback.
- AuditLogger backed by lark_inbound_audit; signature deliberately
  body-free so callers cannot leak content into the drop log.
- ChatSessionService: find-or-create chat_session via the binding
  table (winner-takes-all on the UNIQUE race), append-with-dedup, /issue
  parser, "previous user message" fallback for bare `/issue` invocation.
- Dispatcher orchestrates the inbound pipeline in one place:
  installation routing → group-mention filter → identity check → ensure
  session → append+dedup → /issue → enqueue chat task. Group sessions
  use the installer as creator (stable workspace identity); p2p uses
  the sender. Agent-offline path falls through with OutcomeAgentOffline
  so the WS adapter can reply with the offline notice from §4.6.
- BindingTokenService: random URL-safe token, SHA-256 stored hash,
  15-min TTL pinned at the application AND the DB CHECK; Redeem
  returns the same opaque error for all rejection cases (no timing
  oracle on replay).
- Unit tests for the parser (13 cases), dispatcher (8 cases via fake
  Queries/Chat/Audit/IssueCreator/Enqueuer), and binding-token
  hash/entropy. Real-DB integration tests for OAuth + token redeem
  land alongside the HTTP handlers in the next commit.

Out of scope for this commit (next ones on the same feature branch):
OAuth callback, HTTP routes, WebSocket hub, outbound card patcher,
frontend.

* feat(integrations/lark): installation HTTP surface + secretbox-gated wiring (MUL-2671)

Lands the HTTP boundary on top of the inbound services from the
previous commit. What ships:

- InstallationService.Upsert: the only path that writes
  lark_installation. Encrypts app_secret with the secretbox passed in
  at construction time; refuses to fall back to plaintext storage
  (returns an error from the constructor if no Box is supplied), so a
  misconfigured dev environment cannot accidentally land a row with
  cleartext credentials. Revoke flips status without DELETE so audit
  trail survives.

- HTTP handlers under /api/workspaces/{id}/lark/:
  * GET  /installations           — member-visible (Integrations tab
                                    renders for non-admins). Soft 200
                                    with empty list + configured:false
                                    when MULTICA_LARK_SECRET_KEY is
                                    unset, so the tab does not error
                                    on self-host that has not opted in.
  * POST /installations           — admin-only; 503 when not configured.
                                    Re-validates agent_id ∈ workspace
                                    before accepting credentials so a
                                    cross-workspace agent UUID is
                                    rejected.
  * DELETE /installations/{id}    — admin-only; workspace-scoped lookup
                                    so one workspace cannot revoke
                                    another's installation by UUID
                                    guess.

- POST /api/lark/binding/redeem (user-scoped, no workspace context):
  the only path that mints a lark_user_binding row from user action.
  Redeemer identity comes from the session, not the token, so a stolen
  link cannot bind an open_id to an attacker's Multica user. The
  composite FK on lark_user_binding cascades the binding away if the
  user is not (or no longer) a workspace member, so a non-member who
  steals the link gets 403 at the DB layer.

- Two new event-bus types in protocol.events:
  EventLarkInstallationCreated, EventLarkInstallationRevoked.

- Router wiring: MULTICA_LARK_SECRET_KEY drives a conditional
  initialization of h.LarkInstallations + h.LarkBindingTokens. When
  unset, the integration disables itself with an INFO log and the
  rest of the server boots normally.

- Handler tests cover all four not-configured short-circuits.
  Happy-path integration tests (real DB, full create→list→revoke
  cycle and token mint→redeem) ship alongside the WS hub PR.

* fix(integrations/lark): close binding-token rebind & typed task errors (MUL-2671)

Two must-fixes from PR review on HEAD 87ad15e1:

1. Binding-token redeem could be used to grab an already-bound Lark
   open_id. Two changes harden the path:
   - lark.sql `CreateLarkUserBinding` now gates ON CONFLICT DO UPDATE
     on `multica_user_id = EXCLUDED.multica_user_id`, so a cross-user
     rebind via a second valid token returns zero rows instead of
     silently switching ownership.
   - `BindingTokenService.RedeemAndBind` consumes the token and writes
     the binding row inside one transaction. A failed bind no longer
     burns the token; a successful bind never leaves a consumed-but-
     unused token. Distinct typed errors: ErrBindingTokenInvalid (410),
     ErrBindingAlreadyAssigned (409), ErrBindingNotWorkspaceMember
     (403). The handler maps each to its own status code.

2. Dispatcher collapsed every `EnqueueChatTask` error to
   `OutcomeAgentOffline`, hiding infra failure and misusing the
   "offline" label for cases (e.g. archived agent) where it doesn't
   fit. Now:
   - `service.EnqueueChatTask` returns `ErrChatTaskAgentNoRuntime` and
     `ErrChatTaskAgentArchived` as sentinel errors; DB / load / insert
     failures stay wrapped as ordinary errors.
   - Dispatcher uses `errors.Is` to map only the productizable cases
     (`OutcomeAgentOffline`, new `OutcomeAgentArchived`); any other
     error is returned to the WS adapter so it can retry or page
     instead of disguising the outage as an offline card.

A daemon that's merely disconnected is still NOT an error — as long
as `agent.runtime_id` is set the chat task enqueues and waits for the
daemon to claim it on next online (returns `OutcomeIngested`).

* test(integrations/lark): guard binding-token sentinel contract (MUL-2671)

Two unit tests that document and protect the must-fix invariants
without requiring a DB:

1. TestRedeemAndBindRequiresTxStarter — if a future refactor wires
   up BindingTokenService without a TxStarter, RedeemAndBind must
   fail fast with a clear error rather than nil-panic on Begin.
   The atomicity contract (consume + bind commit together) depends
   on that transaction existing.

2. TestBindingErrorSentinelsAreDistinct — the HTTP handler maps
   ErrBindingTokenInvalid → 410, ErrBindingAlreadyAssigned → 409,
   ErrBindingNotWorkspaceMember → 403. Accidentally aliasing them
   (e.g. var ErrBindingAlreadyAssigned = ErrBindingTokenInvalid)
   would silently regress the response codes without any other
   test catching it.

* feat(integrations/lark): WS hub orchestrator + outbound card patcher (MUL-2671)

The hub owns one supervisor goroutine per active installation. Each
supervisor acquires the WS lease via the existing CAS query, runs an
EventConnector (interface — real Lark wire protocol lands in a follow-up
behind it), renews the lease on a tighter cadence than the TTL, and
backs off (with jitter) on connector failure. Lease loss tears the
connector down cleanly; revocation is reaped on the next sweep. Per-
process node id satisfies §4.4 multi-replica safety: at most one Hub
globally holds the lease for any installation.

The patcher subscribes to task / chat-done events on the existing
events.Bus and keeps the per-task Lark interactive card in sync
(thinking → streaming → final | error). Card binding is per-task as
required by §4.5; throttled patches via an in-memory last-patched map;
final / error transitions bypass the throttle so the user always sees
the terminal state. The Renderer is plug-replaceable so the product
card template can evolve without touching transport.

The APIClient interface centralizes the Lark Open Platform surface
this package needs (send card, patch card, send binding prompt,
exchange OAuth code). The default stubAPIClient returns
ErrAPIClientNotConfigured for every transport call so a misconfigured
deployment fails loudly instead of dropping cards silently. Real
implementation lands in a follow-up; OAuth callback + frontend entries
land in the next commits on this branch.

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

* feat(integrations/lark): OAuth install start / callback (MUL-2671)

OAuthService builds a signed-state Lark authorization URL the frontend
can render as a QR (or open directly), then on callback verifies the
HMAC-protected state, exchanges the OAuth code for installation
credentials via APIClient.ExchangeOAuthCode, and persists the row via
InstallationService.Upsert (which keeps app_secret encryption inside a
single chokepoint).

State token format: workspaceID.agentID.initiatorID.expiresUnix.nonce.sig
— HMAC-SHA256 over the first five fields with a deployment-level
secret. TTL defaults to 10 minutes (covered by tests). Three failure
modes (invalid state / expired state / missing code) map to typed
errors so the HTTP handler can emit a single lark_error= query param
the frontend uses to pick copy.

Both endpoints degrade cleanly: the at-rest key gate (already in place)
returns 503 from /install/start when the InstallationService is nil,
and the OAuth gate (MULTICA_LARK_OAUTH_APP_ID / _SECRET / _REDIRECT_URI
/ _STATE_SECRET) returns configured:false from /install/start so the
frontend can render "configure manually instead" without an error
banner. /install/callback always finishes with a redirect to
/settings?tab=lark carrying either lark_installed=1 or lark_error=<code>.

Tests cover signed-URL shape, missing-config rejection, tampered state,
expired state, propagated exchange error, and the no-config redirect
path on the HTTP handler.

* feat(views/lark): settings tab + agent bind button + /lark/bind redemption page (MUL-2671)

Adds the user-facing Lark surface across the shared packages:

- packages/core/types/lark.ts — wire shapes that mirror server/internal/
  handler/lark.go. Optional fields default to undefined so older desktop
  builds keep parsing if the server adds new keys (CLAUDE.md → API
  Response Compatibility).
- packages/core/lark/{queries,index}.ts — Tanstack Query options keyed
  by workspace id; realtime sync invalidates `installations(wsId)` on
  `lark_installation:*` events.
- packages/core/api/client.ts — listLarkInstallations,
  getLarkInstallURL, deleteLarkInstallation, redeemLarkBindingToken.
- packages/views/settings/components/lark-tab.tsx — Settings → Lark
  panel. Listing is member-visible (matches backend); disconnect is
  admin-only. Empty state points users at the per-Agent bind entry,
  matching the (workspace_id, agent_id) UNIQUE: there is no
  "pick an agent" UI here because the bind URL is per-agent.
- LarkAgentBindButton (same file) is the per-Agent CTA the Agent
  detail page imports. Opens the OAuth URL in a new tab; the callback
  bounces back to /settings?tab=lark with a query param the panel
  reads for inline confirmation copy.
- packages/views/lark/bind-page.tsx — the Bot's "you need to bind"
  destination. Requires session before redeeming, distinguishes the
  410/409/403 backend responses into distinct copy.
- apps/web/app/lark/bind/page.tsx — Next.js route wrapping the shared
  bind page in a Suspense boundary (Next 15 useSearchParams rule).

i18n: all user-facing strings land in en/zh-Hans, settings tab nav
includes a Sparkles-iconed Lark entry, bind-page copy lives under
common.lark_bind so it works pre-workspace-context too. typecheck +
lint clean.

* chore(integrations/lark): wire outbound Patcher into server bootstrap (MUL-2671)

Constructs the Patcher next to the existing Installation/BindingToken
wiring in router.go and Register()s it on the event bus. With the stub
APIClient any actual transport call surfaces ErrAPIClientNotConfigured;
once the real Lark client lands, swap NewStubAPIClient for the real
implementation here without touching the Patcher's subscription logic.

doc.go updated to reflect everything the package now contains (Hub,
Patcher, OAuthService, APIClient interface). The Hub itself is NOT
booted here yet — it needs an EventConnector implementation for the
Lark long-connection wire protocol, which lands in a follow-up; the
orchestrator code and its unit tests are in place so that follow-up
can focus on the WS protocol rather than lifecycle plumbing.

* fix(integrations/lark): address Elon 二审 5 must-fix items (MUL-2671)

- Hub: renewer cancels run ctx on lease loss so the connector exits
  even if its wire I/O is blocked, keeping the §4.4 ownership
  invariant intact under lease theft.
- Hub: EventEmitter returns (DispatchResult, error) so the real
  connector can post the matching Lark-side card (needs_binding,
  agent_offline, agent_archived) and react to infra failures instead
  of silently logging at the seam.
- Dispatcher: top-level message_id dedup runs before group filter
  and identity check, so a reconnect storm cannot re-fire binding
  prompts or re-spam not_addressed_in_group audit rows; the in-
  AppendUserMessage dedup is removed since the table-level UNIQUE
  is the ultimate backstop.
- OAuth: HandleCallback auto-binds the installer via the new
  InstallerBinder seam (BindingTokenService implements it), so the
  §2.1 "scan to bind, you're done" promise holds end-to-end.
  validateExchangeResult now requires installer open_id; new error
  reason codes wired through the callback redirect.
- Frontend / handler: install_supported listing field + StartLark-
  Install short-circuit on stub APIClient hide install entry points
  (Settings tab + per-agent button) while no real Lark HTTP client
  is wired, so users do not land in an OAuth flow that fails at
  exchange.

Includes tests for each fix (lease-loss cancel, emit error
propagation, dedup ordering, OAuth installer-bind contract, stub-
client install gate) and i18n strings for the new preview state.

* fix(integrations/lark): two-phase dedup so infra failures do not swallow messages (MUL-2671)

The pre-fix top-level dedup wrote the lark_inbound_message_dedup row before
EnsureChatSession / AppendUserMessage. An infra error in either step left
the row in place and a WS-adapter retry was mis-classified as a duplicate,
so the user's Lark message was permanently lost without ever landing in
chat_session.

Make dedup two-phase:

  - ClaimLarkInboundDedup acquires an in-flight claim (processed_at NULL).
    Stale claims older than 60 s are re-takeable so a process crash does
    not strand the message_id.
  - MarkLarkInboundDedupProcessed flips processed_at on durable success
    (audit row OR chat_message + session touch).
  - ReleaseLarkInboundDedup deletes the in-flight row on infra failure
    before any durable side effect, so the retry can re-claim immediately.

Dispatcher.Handle now finalizes the claim exactly once based on whether
the inner pipeline reached a durable outcome — chat_message commit being
the transition point (errors past it Mark, errors before it Release).

Regression tests cover the two failure variants Elon flagged plus the
inverse invariants (durable-error Marks, drops Mark, in-flight replays
drop, stale claims re-claim).

* fix(integrations/lark): owner-fence dedup claim to close the double-write windows (MUL-2671)

The two-phase Claim/Mark/Release fix from the previous commit closed the
"infra error swallows a replay" gap but left two windows that could still
write a chat_message twice for the same Lark message_id:

  1. Stale-reclaim race. Worker A claims at t=0, runs slowly past the
     60 s staleness TTL but is still alive. Worker B sees the row as
     stale and re-takes the claim. A reaches AppendUserMessage and
     commits a second chat_message.

  2. Mark window. Worker A commits chat_message but the post-pipeline
     MarkLarkInboundDedupProcessed fails (DB hiccup) or the process
     crashes before it runs. 60 s later a retry treats the in-flight
     row as stale, re-claims it, and writes a second chat_message.

Close both with owner fencing + same-tx Mark:

  - lark_inbound_message_dedup now carries a `claim_token` UUID;
    ClaimLarkInboundDedup mints a fresh one on insert and on stale
    re-take, so a reclaim ROTATES the token.

  - MarkLarkInboundDedupProcessed and ReleaseLarkInboundDedup are
    fenced on (message_id, claim_token, processed_at IS NULL) and
    return rowsAffected. Zero means our token is no longer live, and
    the caller treats it as a no-op (not an error).

  - AppendUserMessage invokes MarkLarkInboundDedupProcessed INSIDE its
    chat_message+session tx (qtx). If the token has been rotated by a
    concurrent reclaim, the Mark matches zero rows and the method
    returns ErrClaimLost; the deferred Rollback unwinds the
    chat_message insert, so the other holder is the sole writer. The
    durable write and the Mark therefore commit (or roll back)
    atomically — there is no "committed but not yet Marked" window
    for a crash or retry to exploit.

Dispatcher.processClaimed now returns a tri-state dedupFinalize directive
(none / mark / release): finalizeNone for the in-tx Mark path (and
ErrClaimLost), finalizeMark for audit-drop branches and the defensive
post-Append-success fallback, finalizeRelease for pre-durable infra
errors. ErrClaimLost is translated into OutcomeDropped + DropReason-
Duplicate at the Handle boundary, matching what the WS adapter expects
for a "another worker is the writer" outcome.

Regression tests:

  - TestDispatcher_StaleReclaimRaceDoesNotDoubleWrite injects worker
    B's reclaim via a beforeAppend hook so the claim_token rotates
    between Claim and AppendUserMessage. Asserts worker A's
    AppendUserMessage returns ErrClaimLost (no chat_message
    committed), the dispatcher surfaces a duplicate drop, the token
    rotated to a value distinct from A's original, and a follow-up
    replay still duplicate-drops.

  - TestDispatcher_InTxMarkPreventsPostCommitReclaim verifies the
    "Mark window" case is unreachable: a successful in-tx Mark
    produces exactly one Mark call (no post-finalize duplicate), the
    row is terminal, and a retry with dedupReclaim=true still
    duplicate-drops without re-rotating the token.

  - TestDispatcher_InTxMarkSucceedsAndSkipsPostFinalize pins the
    positive contract: DedupMarked=true must make applyFinalize a
    no-op (no extra Mark, no Release).

fakeQueries gains a fakeDedupRow model carrying (processed, token,
rotations) so the test seam matches production's UPDATE-with-WHERE
semantics; fakeChat gains a beforeAppend hook to inject race timing.

go test ./... and go vet ./... pass.

* feat(integrations/lark): real Lark HTTP APIClient for IM v1 send/patch (MUL-2671)

Lands the production Lark Open Platform HTTP APIClient that replaces
the stub for outbound transport. The patcher's "thinking → streaming
→ final | error" card lifecycle and the dispatcher's binding-prompt
card both now reach Lark for real once MULTICA_LARK_HTTP_ENABLED=true.

Scope of this stage:

  - tenant_access_token retrieval via /open-apis/auth/v3/
    tenant_access_token/internal, cached in-process per app_id with a
    60s safety margin against Lark's `expire` value. Sub-2-minute
    expires are clamped to 120s so we never cache an entry that's
    already past its safe window.
  - SendInteractiveCard: POST /open-apis/im/v1/messages?receive_id_type=chat_id
    returning the Lark message_id the Patcher persists in
    lark_outbound_card_message for later patches.
  - PatchInteractiveCard: PATCH /open-apis/im/v1/messages/:id with
    the full re-rendered card body (Lark's update endpoint replaces,
    not deep-merges).
  - SendBindingPromptCard: open_id-targeted interactive card with a
    primary "去绑定" CTA pointing at the redemption URL. Template is
    co-located with the transport so the dispatcher never has to know
    about Lark's card schema.
  - Token-error invalidation: Lark codes 99991663 (expired) /
    99991664 (invalid) drop the cached token so the next call
    refreshes from /tenant_access_token/internal instead of looping
    on a stale entry.

Out of scope (deferred to follow-up stages):

  - ExchangeOAuthCode stays unimplemented behind
    ErrAPIClientNotConfigured. The PersonalAgent install handshake's
    response shape (returning per-installation app credentials in a
    single call) is not yet verified against the production endpoint,
    and a silent mis-fill of OAuthExchangeResult would corrupt
    lark_installation rows past validateExchangeResult. Operators
    continue to use the manual-paste InstallationService path until
    the OAuth stage lands.
  - Inbound WS EventConnector — Hub's ConnectorFactory still needs a
    real wire-protocol implementation.

Wiring:

  - MULTICA_LARK_HTTP_ENABLED=true switches router.go from the stub
    to the real client. MULTICA_LARK_HTTP_BASE_URL overrides the
    default open.feishu.cn host (set to open.larksuite.com for the
    Lark international tenant, or to an httptest URL for integration
    tests).
  - The OAuth handler now also receives the real client (its
    ExchangeOAuthCode still surfaces ErrAPIClientNotConfigured, so
    callback behavior is unchanged until that stage lands).

Tests (19 new cases against an httptest.Server fake):

  - happy path send/patch/binding-prompt round trips, asserting URL
    query params, body shape, Authorization header
  - token cache: 3 sends share one /tenant_access_token/internal hit
  - token refresh after clock-driven expiry
  - sub-margin expire clamping (10s expire → cached for >= safety
    margin of wall-clock)
  - Lark error code surfacing (230001 send, 230002 patch, 10003 auth)
  - token-expired (99991663) invalidates the cache; caller's retry
    re-fetches and succeeds
  - non-2xx HTTP status surfaces "http 500: …"
  - input validation: missing chat_id short-circuits BEFORE auth
    round-trip, missing card json / open_id / bind url all fail
    pre-flight without hitting Lark
  - ExchangeOAuthCode still returns ErrAPIClientNotConfigured
  - binding-prompt template carries the BindURL and the localized
    "去绑定" CTA in valid JSON

go build ./..., go vet ./..., and go test ./internal/integrations/lark/...
pass. Pre-existing handler/router integration tests that require a
real Postgres connection are unaffected by this change.

* fix(integrations/lark): split outbound vs OAuth-install capability + card update_multi (MUL-2671)

Address Elon's two must-fix items from the HEAD a09993b1 review:

1. HTTP outbound and OAuth-install are now distinct APIClient
   capabilities. The new SupportsOAuthInstall() reports whether the
   install flow can succeed end-to-end (i.e. ExchangeOAuthCode is
   implemented); the real httpAPIClient still returns IsConfigured()
   = true (send / patch / binding prompt work) but
   SupportsOAuthInstall() = false until the PersonalAgent install-time
   response shape is pinned. Handler-side `install_supported` and
   StartLarkInstall now gate on SupportsOAuthInstall, so a half-wired
   client never reveals the scan-to-bind UI. larkOAuthErrorReason also
   maps ErrAPIClientNotConfigured to a dedicated
   `oauth_exchange_unimplemented` reason so a raw callback hit no
   longer masquerades as `internal_error`.

2. defaultRenderer now emits config.update_multi=true on every Kind.
   Lark refuses to apply PatchInteractiveCard to a card whose initial
   config doesn't declare it shared/updatable, so the absent flag
   would make every patch after the first send silently no-op on the
   wire while the local outbound status row still flipped to
   streaming/final.

Tests cover both halves of each fix:
- TestHTTPClient_SupportsOAuthInstall_FalseUntilExchangeLands +
  TestHTTPClient_StubReportsBothCapabilitiesFalse pin the new
  capability surface.
- TestStartLarkInstall_TransportOnlyClientReportsNotConfigured +
  TestListLarkInstallations_TransportOnlyClientReportsInstallNotSupported
  pin the handler gate at exactly the half-wired state.
- TestLarkOAuthErrorReason_APIClientNotConfigured pins the mapping
  for both the bare sentinel and the fmt.Errorf-wrapped form
  HandleCallback produces.
- TestDefaultRendererConfigCarriesUpdateMulti covers every CardKind.
- TestHTTPClient_(Send|Patch)InteractiveCard_DefaultRendererBodyHasUpdateMulti
  verify the wire body Lark actually receives carries update_multi
  through both send and patch transport paths.

* feat(integrations/lark): real OAuth code exchange + agent-detail bind entry (MUL-2671)

Stages the install side of the MVP critical path on top of the real
HTTP outbound work:

- httpAPIClient.ExchangeOAuthCode runs the production Lark v2 OAuth
  flow: POST /authen/v2/oauth/token to swap the authorization code
  for the installer's open_id, then GET /bot/v3/info under the parent
  app's tenant_access_token to fetch bot_open_id. Result feeds
  InstallationParams unchanged so OAuthService.HandleCallback's
  auto-bind step lights up automatically.

- HTTPClientConfig gains OAuthAppID/OAuthAppSecret, read from the same
  MULTICA_LARK_OAUTH_APP_ID/_APP_SECRET env vars the OAuthConfig
  consumes. SupportsOAuthInstall now mirrors that pair so the install
  capability gate is honest: outbound transport without OAuth creds
  reports configured-but-not-install-supported, exactly like before.

- Agent detail inspector wires the LarkAgentBindButton in a new
  Integrations section, viewer-hidden by canEdit. The button still
  self-hides when SupportsOAuthInstall is false, so a deployment
  without OAuth creds renders the section empty rather than CTA-broken.

- Capability wording cleaned across handler / router / lark-tab to say
  "OAuth-install capability" instead of "real APIClient wired", and
  the misleading TransportOnly... test was renamed/refocused on the
  early-return branch it actually exercises (Elon non-blocking note).

* fix(integrations/lark): identity-only OAuth + atomic bind (MUL-2671)

Addresses Elon's round-4 must-fix items on PR #3277:

1. OAuth v2 token → user_info chain now matches Lark's official
   user-OAuth shape. `httpAPIClient.ExchangeOAuthCode` POSTs
   /open-apis/authen/v2/oauth/token (RFC 6749: top-level
   access_token, NO open_id), then GETs /open-apis/authen/v1/user_info
   with the user_access_token as Bearer to obtain the installer's
   open_id / union_id. The test fixture now reflects the real
   wire shape (separate user_info handler; no synthetic open_id in
   the token response).

2. `OAuthExchangeResult` is identity-only — drops the synthesized
   shared-parent AppID / AppSecret / BotOpenID return that broke
   the UNIQUE(app_id) constraint and the dispatcher's per-app_id
   routing. `OAuthService.HandleCallback` no longer Upserts an
   installation row: it looks up the lark_installation already
   provisioned via the manual-paste POST /lark/installations route
   and binds the installer onto it. Two new typed errors —
   ErrInstallationNotProvisioned and ErrInstallationRevoked — map
   to `installation_not_provisioned` / `installation_revoked`
   reasons at the HTTP boundary so the UI can guide the admin.
   The PersonalAgent install API (which would deliver
   per-installation bot credentials at scan time) remains a
   follow-up; until it lands the OAuth flow is identity-binding
   only and the agent-detail bind button stays hidden on
   deployments without OAuth env (capability gate unchanged).

3. The installation lookup + installer bind run inside a single
   DB transaction so a concurrent revoke / re-provision between
   the read and the binding insert cannot leak a half-applied
   state. `InstallerBinder.BindInstaller` is renamed to
   `BindInstallerTx` and accepts the OAuth-service-owned
   transaction's qtx; the binding_token redemption path is
   unchanged.

4. `validateExchangeResult` is simplified to require only the
   installer's open_id; the obsolete ErrExchangeMissingAppID /
   AppSecret / BotOpenID sentinels are removed (no caller can
   trip them now). The oauth_test suite is rewritten to use a
   stub failTxStarter so tests covering state-token verification
   and exchange-error propagation remain DB-free, while a new
   TestOAuthCallbackOpensTxAfterValidExchange pins the post-must-fix
   order (state ok + exchange ok ⇒ Begin runs before any lookup
   or bind, and a Begin failure aborts cleanly with no bind).

* feat(integrations/lark): device-flow scan-to-install (MUL-2671)

Replaces the manual paste-credentials install path + identity-only
OAuth callback (rejected in product review: too many steps before a
user sees value) with a true single-step scan-to-install built on
Lark's RFC 8628 device-flow registration endpoint
(POST accounts.feishu.cn/oauth/v1/app/registration) — the same
protocol the official larksuite/oapi-sdk-go/scene/registration
package and zarazhangrui/feishu-claude-code-bridge use.

User journey: admin clicks "Bind to Lark" on the Agent detail page
→ QR dialog opens → admin scans in the Lark app on their phone →
authorizes the new PersonalAgent → dialog auto-closes with the new
installation visible. No app_id / app_secret to copy, no Lark
developer console visit, no Multica-side OAuth env to configure.

Backend (server/internal/integrations/lark):
- registration.go — inline ~280-line RFC 8628 client. Begin posts
  archetype=PersonalAgent / auth_method=client_secret /
  request_user_info=open_id; Poll follows the upstream SDK's
  state machine including the tenant-brand mid-stream domain swap
  to accounts.larksuite.com when a Lark-international account
  authorizes. SDK is NOT vendored — one endpoint isn't worth
  dragging the full oapi-sdk-go + transitive deps.
- registration_service.go — owns the in-process session store
  + background polling goroutine. On success calls APIClient.GetBotInfo
  (the new IM-side endpoint added below) and writes
  lark_installation + the installer's lark_user_binding inside
  one DB transaction so a half-applied install can never land.
  Stable error_reason codes (expired / access_denied /
  lark_protocol_error / bot_info_failed / installation_conflict /
  installer_bind_failed / internal_error) drive the UI copy
  without parsing prose.
- client.go / http_client.go — drops ExchangeOAuthCode and
  SupportsOAuthInstall (no longer applicable: device-flow returns
  identity alongside credentials in one response); adds GetBotInfo
  which mints a tenant_access_token from the freshly-minted
  client_id / client_secret and calls /open-apis/bot/v3/info for
  the bot_open_id. install_supported now gates on IsConfigured()
  (real HTTP client wired) instead of a separate OAuth capability.
- binding_token.go — absorbs InstallerBindParams / InstallerBinder
  (previously in oauth.go), retargets the doc-comment from the
  OAuth caller to the device-flow caller.
- Deletes oauth.go + oauth_test.go entirely.

Handler & router (server/internal/handler, server/cmd/server):
- POST /api/workspaces/{id}/lark/install/begin — opens a new
  registration session, returns {session_id, qr_code_url,
  expires_in_seconds, poll_interval_seconds}. Admin-only.
- GET /api/workspaces/{id}/lark/install/{sessionId}/status —
  polling endpoint, returns {status, installation_id?, error_reason?,
  error_message?}. Workspace-scoped lookup so a stolen session_id
  cannot be polled from another workspace. Admin-only.
- Removes POST /lark/installations (paste form),
  GET /lark/install/start (OAuth-redirect entry), and
  GET /api/lark/install/callback (OAuth redirect target).
- Removes MULTICA_LARK_OAUTH_APP_ID / _APP_SECRET / _REDIRECT_URI /
  _STATE_SECRET / _AUTHORIZE_URL / _SUCCESS_URL env vars. Self-host
  operators no longer need a parent Lark app at all.

Frontend (packages/core, packages/views):
- New types BeginLarkInstallResponse / LarkInstallStatusResponse
  + matching API methods (beginLarkInstall / getLarkInstallStatus);
  drops getLarkInstallURL.
- LarkAgentBindButton opens LarkInstallDialog instead of a
  window.open() to Lark's authorize page. The dialog uses
  react-qr-code (catalog) to render the verification_uri_complete
  inline as SVG (no external CDN image), polls status at the
  server-supplied cadence, auto-closes on success, offers
  "scan again" on terminal failure. Per CLAUDE.md "Enum drift
  downgrades, not crashes", error_reason switch has a default
  fallback so an older desktop build on a newer server still
  renders the generic failure copy.
- Adds the device-flow strings to en + zh-Hans settings.json;
  removes the obsolete OAuth-not-configured copy.

Verified locally:
  - go build ./... / go vet ./... clean
  - go test ./internal/integrations/lark/... — all green
    (existing tests + 15 new registration / GetBotInfo tests)
  - go test ./internal/handler -run 'Lark|Binding' — all green
  - pnpm typecheck — all 6 packages clean
  - pnpm lint — 0 errors (15 pre-existing warnings, none in changed files)
  - pnpm --filter @multica/views test — 859/859 pass

Pre-existing failures in server/internal/middleware (column
"profile_description" missing from local test DB) reproduce against
the parent commit and are unrelated to this change.

* fix(integrations/lark): gate bind CTA to workspace admins, terminate QR polling on 4xx (MUL-2671)

Two frontend must-fixes from the PR #3277 二审:

1. LarkAgentBindButton now self-hides for non-admin viewers in addition
   to the existing install_supported check. The agent-detail page mounts
   the button under `canEdit`, which canEditAgent lets agent owners
   through even when they are not workspace admins — but the backend
   gates POST /lark/install/begin and the status poll on owner/admin
   (router.go:478-487), so the previous behavior shipped a CTA that was
   guaranteed to 403. The new gate reads workspace role from the same
   member list the settings tab already uses.

2. The status polling loop now terminates on 404 (session gone — server
   restarted, multi-instance routing, or in-process GC swept it) and
   403/401 (permission revoked mid-session). Previously every error
   path scheduled another setTimeout, which trapped the user on a stale
   QR forever. ApiError gives us the HTTP status verbatim; terminal
   responses set status=error with stable error_reason codes
   (session_lost, forbidden) that flow through the existing dialog
   switch + retry/close affordances. 5xx + network blips still retry.

i18n: new install_error_session_lost / install_error_forbidden in en
and zh-Hans, with default fallback preserved per the enum-drift rule.

Coverage: 6 new vitest cases — admin/owner allow, member deny,
unsupported-install deny, and the two terminal-error polling paths
using fake timers to assert the loop stops scheduling.

Also clears a handful of stale OAuth/manual-install doc comments
flagged in the review (non-blocker cleanup): doc.go's §10 now points
at RegistrationService, installation.go's input-shape doc loses the
OAuth-callback half, and client.go's stubAPIClient comments no longer
reference OAuth callbacks.

* docs(integrations/lark): describe gate as device-flow install in agent-detail integrations comment (MUL-2671)

The comment block above the agent-detail Integrations section still
described the capability gate as 'server-side OAuth-install'. The
OAuth path is gone — install is now device-flow per RFC 8628 — so the
comment now reads 'server-side device-flow install capability gate'.

Pure comment change; behavior is unchanged. Cleans up the nit Elon
called out in PR #3277 二审 (MUL-2671).

* feat(integrations/lark): wire inbound pipeline + WS Hub at boot (MUL-2671)

Stage 3.a of MUL-2671. Hub class, Dispatcher, ChatSessionService and
AuditLogger have all been implemented and tested in prior PRs but
none of them was constructed at boot, so the in-process plumbing
was never exercised end-to-end. This change wires them together
behind the same `MULTICA_LARK_SECRET_KEY` gate that already gates
InstallationService / RegistrationService, and starts the Hub under
the existing `sweepCtx` so it winds down alongside the other
long-running workers after HTTP drain.

The real long-conn EventConnector is still pending; the factory
hands every supervisor a shared NoopConnector that holds the lease
and emits nothing. That lets staging exercise the lease /
supervisor / shutdown lifecycle against real DB rows without
committing to the Lark wire protocol implementation. Swapping in
the real connector is a single line change in the same router
block; the Dispatcher / ChatSessionService / Hub seams stay frozen.

## Why a noop placeholder, not a stub-or-skip

The Hub's value is mostly its lifecycle: §4.4 ownership lease,
LeaseRenewInterval / LeaseTTL, supervisor reap on revoke, clean
release on shutdown. None of that runs unless the Hub is actually
started. Holding off until the real connector lands means the next
PR has to debut both pieces simultaneously; wiring the supervisor
loop first lets the real connector PR be a focused, reviewable
swap.

## Changes

- `internal/integrations/lark/noop_connector.go` — `NoopConnector`
  implementing `EventConnector`: blocks on ctx until the Hub
  cancels (lease loss / shutdown / revoke), emits no events, logs
  on enter/exit so operators see exactly which installation the
  supervisor is holding the lease for.
- `internal/integrations/lark/noop_connector_test.go` — verifies
  the connector blocks until ctx cancel, returns nil on clean exit,
  never invokes the emit callback, and the factory shares a single
  connector instance across installations.
- `internal/handler/handler.go` — new `LarkHub *lark.Hub` field on
  `Handler`. Nil when the Lark integration is disabled.
- `cmd/server/router.go` — inside the existing Lark wiring block,
  construct `AuditLogger`, `ChatSessionService` (with `*pgxpool.Pool`
  for the in-tx dedup Mark), `Dispatcher` (wiring `h.IssueService`
  and `h.TaskService` so `/issue`-created issues share counter /
  duplicate guard / project boundary / broadcast / analytics with
  the rest of the product), and the `Hub` with the
  `NoopConnectorFactory`. `NewRouterWithOptions` now returns
  `(chi.Router, *handler.Handler)` so main.go can drive Hub
  lifecycle; `NewRouter` discards the handler.
- `cmd/server/main.go` — start the Hub under `sweepCtx` after the
  other background workers, and `Wait` on it after HTTP drain +
  sweep cancel so the lease renewer can issue a final release
  before exit. Skipped entirely when `h.LarkHub == nil`.

## Test plan

- [x] `go build ./...` clean
- [x] `go vet ./...` clean
- [x] `go test ./internal/integrations/lark/...` (new noop tests +
      existing hub / dispatcher / chat_service / registration /
      binding_token / outbound / issue_command suites) — all pass
- [x] `go test ./internal/handler -run 'TestLark|TestRedeemLarkBinding'`
      pass — handler-side Lark surfaces unchanged
- [x] `go test ./internal/service/... ./internal/util/secretbox/...`
      pass
- [x] `pnpm --filter @multica/views exec vitest run settings/components/lark-tab`
      pass (6/6) — frontend lark surfaces unchanged
- [ ] Local broad `go test ./internal/handler/...` still blocked by
      the pre-existing test DB schema drift Elon flagged in the
      previous round (`column "metadata" does not exist`,
      unrelated to this change); CI is the authoritative check.
- [ ] Manual end-to-end deferred until the real long-conn
      EventConnector lands (next stage).

* fix(integrations/lark): bound Hub lease release + shutdown wait (MUL-2671)

Lease release used context.Background(); a stalled DB pool could pin
shutdown indefinitely. Add LeaseReleaseTimeout (5s default) and
ShutdownTimeout (15s default) to HubConfig, route releaseLease through
a bounded context, and expose WaitWithTimeout for main.go so a wedged
supervisor degrades to LeaseTTL expiry on the next replica instead of
blocking process exit. Also correct the LarkHub field comment in
handler.go: the Hub is wired whenever the at-rest secret key is set,
independent of whether the outbound HTTP APIClient is configured.

* feat(integrations/lark): real WS long-conn connector + ctx-cancel-breaks-read (MUL-2671)

Replaces NoopConnectorFactory with a production EventConnector that
opens Lark's event-subscription WebSocket. Gated behind
MULTICA_LARK_WS_ENABLED so staging boots stay on the noop path until
operators opt in, and falls back to noop with a warning when the WS
flag is set without MULTICA_LARK_HTTP_ENABLED (the real connector
needs the cached tenant_access_token).

Why this connector exists separately from the Hub: gorilla/websocket
ReadMessage blocks on the underlying TCP socket and does not observe
context. The watchdog goroutine inside WSLongConnConnector.Run closes
the conn the moment ctx fires, so lease loss / shutdown breaks the
blocking read in bounded time — exactly the invariant Hub
renewLeaseUntil's runCancel depends on for the "at most one active WS
per installation across replicas" guarantee. Tests cover this
explicitly (TestWSConnectorRunReturnsOnCtxCancelEvenWhenReadIsBlocked).

The Lark wire surface is split into three swappable seams so the
transport layer stays tested in isolation:

  - EndpointFetcher (POST /event-subscription/v1/connection_token)
    resolves a one-shot wss URL per Run. No caching — replaying a
    one-shot token would look like a Lark outage.
  - FrameDecoder turns one raw JSON envelope into an InboundMessage
    or a "control / heartbeat / drop" verdict. Decoder errors log
    + drop the frame; they do NOT tear down the connection.
  - CredentialsProvider wraps InstallationService.DecryptAppSecret
    so plaintext app_secret lives in memory only during a Run.

Also fixes the handler.go LarkHub comment: it still said "joins on
Wait during graceful shutdown" but main.go has used WaitWithTimeout
(bounded wait) for several commits. Comment now matches.

* feat(integrations/lark): align WS to official binary Frame protocol + DispatchResult outbound replies (MUL-2671)

Two must-fix items from Elon's review of PR #3277:

1. WS protocol layer rewritten to match the official Lark Go SDK
   (`larksuite/oapi-sdk-go/v3/ws`):
   - Bootstrap is `POST /callback/ws/endpoint` with AppID/AppSecret
     in the body (no tenant_access_token bearer). Response carries
     wss URL + ClientConfig (PingInterval / ReconnectInterval /
     ReconnectNonce / ReconnectCount).
   - `service_id` is parsed from the wss URL query and used as
     Frame.Service on every outbound frame.
   - Wire envelope is the binary protobuf `pbbp2.Frame` (hand-rolled
     via protowire to avoid pulling the whole SDK in, byte-identical
     field tags). JSON payloads are nested inside Frame.Payload.
   - Inbound data frames are ACKed with a `Response{code:200,...}`
     JSON payload that reuses the inbound headers; infra failures
     produce code=500 so Lark retries.
   - Ping is the app-layer binary `NewPingFrame(serviceID)` at the
     server-supplied cadence; WebSocket protocol PING is removed
     (Lark ignores it). Server-initiated pings get a pong reply.
   - ctx-cancel-breaks-read invariant preserved via the watchdog
     goroutine that closes the conn on ctx.Done; the read loop and
     ping goroutine serialize their writes through a single mutex.

2. `DispatchResult` outbound replies wired via a new `OutcomeReplier`:
   - `OutcomeNeedsBinding` mints a one-shot binding token and sends
     the binding prompt card to the sender's open_id.
   - `OutcomeAgentOffline` / `OutcomeAgentArchived` push a notice
     card into the chat with the agent name + Chinese copy matching
     §4.6.
   - `OutcomeIngested` stays owned by the Patcher; `OutcomeDropped`
     is silent.
   - The replier is best-effort: outbound failures are logged and
     swallowed so a Lark outage cannot stall the inbound pipeline.
   - Hub installs the noop replier by default; router wires the
     production `LarkOutcomeReplier` when APIClient.IsConfigured().

PersonalAgent long-conn risk surfaced (open per Feishu docs:
`长连接模式仅支持企业自建应用`). The implementation works for any
app archetype; the open question is whether `/callback/ws/endpoint`
accepts PersonalAgent credentials in practice. Surfacing the Lark
code+msg verbatim from the bootstrap response so an operator running
the smoke test sees the exact failure rather than a generic timeout.

* fix(integrations/lark): byte-compat Frame marshal, chunk reassembly, ACK off reply critical path (MUL-2671)

Three protocol blockers from Elon's review of 9540008a:

1. Frame.Marshal is now byte-identical to oapi-sdk-go/v3/ws/pbbp2.Frame:
   - SeqID/LogID/Service/Method (proto2 req) emit unconditionally even at zero
   - PayloadEncoding/PayloadType/LogIDNew emit unconditionally per gogo
     generated MarshalToSizedBuffer (no zero-guard)
   - Payload uses the SDK's `!= nil` guard (nil omits, []byte{} emits 0-length)
   - ACK payload JSON matches SDK's NewResponseByCode + json.Marshal output
     ({"code":N,"headers":null,"data":null})

   Golden tests pin exact byte sequences for ping/pong/ACK/full/zero
   frames; verified against the real SDK pbbp2.pb.go MarshalToSizedBuffer
   producing identical bytes.

2. Multi-frame events (sum>1) are reassembled via the new chunkAssembler:
   - 5s sliding TTL (matches SDK combine() cache TTL)
   - Lazy GC on admit (no separate sweeper goroutine)
   - Out-of-order seq + duplicate seq idempotent
   - Partial chunks are NOT ACKed (SDK behaviour: only the final chunk's
     ACK confirms the whole event so Lark can retry on partial loss)
   - Connector wires assembler per-Run; state dies with the session

3. OutcomeReplier detached from ACK critical path:
   - HubConfig.ReplyTimeout default 2.5s, strictly under Lark's 3s ACK deadline
   - handleEvent dispatches synchronously (fast DB path), then spawns the
     replier under a fresh background ctx with WithTimeout(ReplyTimeout)
   - Hub.replyWg tracks in-flight replies; Hub.Wait / WaitWithTimeout
     drain them so shutdown is bounded
   - Noop replier short-circuits inline (no goroutine cost when outbound
     APIClient isn't configured)

   Proof tests:
   - TestHubScheduleReplyReturnsImmediately: scheduleReply with a 10s
     slow replier returns in <50ms
   - TestHubReplyTimeoutCancelsHungReplier: hung replier ctx fires at
     ReplyTimeout
   - TestHubWaitDrainsInFlightReplies: Wait blocks until replies finish
   - TestHubACKNotBlockedByOutboundReply: end-to-end through the
     connector — data-frame ACK lands within 500ms even when the
     replier hangs 5s

PersonalAgent real-env smoke remains Bohan's decision; this PR closes
the technical blockers Elon flagged.

* docs(service/issue): narrow position concurrency claim to create-create (MUL-2671)

Elon's review of the merge resolution flagged that the comment on the
new NextTopPosition call promised more than the code guarantees:
concurrent manual reorder via UpdateIssue(position) does NOT take the
workspace row lock that IncrementIssueCounter holds, so a create
racing a reorder can still land on the same position. Rewrite the
comment to only claim create-create serialization, which is the
behaviour the lock actually delivers. No code change.

* fix(integrations/lark): keep device-flow polling on RFC 8628 HTTP 400 (MUL-2671)

Lark's device-flow polling endpoint returns HTTP 400 with the JSON
body `{"error":"authorization_pending"}` while the user hasn't scanned
the QR yet — this is the RFC 8628 spec, and the upstream oapi-sdk-go
implements the same handling. Our previous doForm treated ANY non-2xx
as a terminal protocol error, so every install session was killed by
the first poll (~5s after begin) and the install dialog appeared
silently empty: the frontend received status=error +
lark_protocol_error before the user could even read the description.

Fix: doForm now decodes the JSON body first; if it parses, the caller
(Begin / Poll) routes on the body's `error` field, where the existing
switch correctly maps authorization_pending / slow_down to "keep
polling" and access_denied / expired_token to terminal failure. Only
unparseable bodies (5xx HTML proxy pages, gateway timeouts) still
surface as a typed http_NNN RegistrationError.

Three regression tests pin the new behaviour:
- HTTP 400 + authorization_pending → res.Status="authorization_pending"
- HTTP 400 + access_denied → res.Err.Code="access_denied" (terminal)
- HTTP 502 + HTML body → http_502 RegistrationError

Verified against the live local env: install/begin -> 200, status
stays "pending" through the first poll cycle, no longer flips to
"error" within seconds.

* fix(views/lark): reset closedRef on every mount so StrictMode double-mount renders QR (MUL-2671)

Empty QR dialog body in the dev env: Bohan opened the bind dialog and
got an empty white area where the QR should have been — no QR, no
"starting" placeholder, no error text. Backend was returning the QR
URL correctly; the bug was on the frontend.

Root cause: React 19 / Next.js dev StrictMode mounts every component
twice (mount → cleanup → mount). The component instance is REUSED
across the simulated remount, which means useRef objects are
preserved. The dialog's `closedRef` lifecycle:

  1. Mount #1: closedRef={current:false}, beginSession() kicked off
     (HTTP request still in flight)
  2. Cleanup runs: closedRef.current=true
  3. Mount #2: beginSession() kicked off again, BUT the ref still
     reads {current:true} from step 2
  4. Both promises resolve. Both hit the post-await guard
     `if (closedRef.current) return;` and bail out before setSession().
  5. Result: session stays null forever. Every conditional in the
     dialog body (beginning/session-pending/success/error) is false →
     empty body.

Fix: reset closedRef.current=false at the START of the effect, not
just at component construction. The cleanup-then-mount pair now
re-arms the guard so subsequent setSession calls actually land.

Regression test wraps the dialog in <StrictMode> and asserts the
QR appears within 2s with the correct value — fails closed if anyone
removes the reset.

* fix(integrations/lark): drop EventTaskCompleted subscription so the chat reply doesn't get overwritten by "Done." (MUL-2671)

Bohan reproduced on the live dev env: agent replies show only a card
saying "Done." in Lark, even though Multica's own chat panel has the
real "Hello! I'm cc…" reply. Tasks succeed end-to-end, but the user
loses the reply on the Lark side.

Root cause: TaskService.CompleteTask publishes two events for every
chat task IN ORDER:

  1. broadcastChatDone(...)       → ChatDonePayload{Content: "Hello!..."}
  2. broadcastTaskEvent(Completed) → map[string]any{task_id, agent_id,...}
                                     (no `content` key)

The Patcher subscribed to BOTH and routed each to finalize(). The
first patch correctly rendered the reply text, the second
patched the same card with an empty payload — chatDoneContent()
returned "" and the renderer fell back to "Done." (default empty-body
copy). The second patch wins because Lark stores whatever was last
applied.

Fix: stop subscribing to EventTaskCompleted in the Patcher and remove
the corresponding switch arm. EventChatDone is the canonical "agent
finished replying" signal for the Lark card path; EventTaskCompleted
is still emitted to the bus for other listeners (web UI, analytics,
task usage) where the lack of content doesn't matter.

Regression test TestPatcherIgnoresEventTaskCompletedForChatTasks
emits ChatDone followed by TaskCompleted on a streaming card and
asserts: exactly one patch, body contains the agent reply, body does
NOT contain "Done.". If anyone re-adds the EventTaskCompleted
subscription, this fails immediately.

* feat(integrations/lark): chat replies as plain text IM messages, not card chrome (MUL-2671)

Bohan reported on the live dev env that even with the agent's reply
shown correctly, every message is wrapped in an interactive card with
the agent name as the header — it feels like a system notification,
not a normal chat reply. He wants the reply to land as a regular Lark
text bubble.

Changes:

- Add APIClient.SendTextMessage backed by Lark's
  /open-apis/im/v1/messages with msg_type=text. JSON-encodes the
  {"text": ...} envelope Lark requires so callers pass raw strings.
- Patcher.Register no longer subscribes to EventTaskQueued /
  EventTaskRunning. There is no more thinking → running → final
  card lifecycle on the success path: it added card chrome without
  buying anything for free-form chat.
- On EventChatDone, the new sendChatReply path posts the assistant
  message content as plain text. Empty content is silently dropped
  rather than rendered as "Done." (the prior fallback that
  confused Bohan).
- Failure path keeps a one-shot error card on EventTaskFailed —
  the visual distinction from a normal reply is genuinely useful,
  and failures are rare enough that the chrome isn't noisy.
- Throttle / lastPatched map / MinPatchInterval / shouldPatch /
  markPatched / loadCardOrSkip are all removed; nothing in the new
  flow patches.

Tests:

- TestPatcherSendsPlainTextOnChatDone pins the new contract: exactly
  one SendTextMessage call, no card sends or patches, content
  matches the ChatDonePayload.
- TestPatcherDropsEmptyChatReply pins the "no more Done. fallback"
  decision — empty content drops, period.
- TestPatcherFailEventSendsErrorCard pins the failure path still
  uses a card (one-shot, no patching).
- TestPatcherIgnoresEventTaskCompletedForChatTasks rewritten for
  text path: ChatDone then TaskCompleted yields exactly one text
  send, no duplicate.
- TestPatcherSkipsWhenNoChatSessionBinding and
  TestPatcherSwallowsInstallationLoadErrors rewritten to drive
  EventChatDone (the new entry point) instead of TaskQueued.
- TestPatcherSendsThinkingCardOnTaskQueued deleted (no more
  thinking card).

* feat(integrations/lark): pre-fill PersonalAgent bot name as "<agent> - Multica" (MUL-2823) (#3520)

The device-flow install left the bot at Lark's auto-generated
"{用户姓名}的智能助手". Lark's registration scene supports pre-filling the
name via a `name` query param on the verification/QR URL (mirrors the
upstream SDK's AppPreset.Name) — a user-editable default that rides on
the QR URL, not the begin POST body (which has no name field).

BeginInstall already loads the agent for its ownership check, so we keep
it and thread `<agent.Name> - Multica` through Begin → decorateQRCodeURL.
A blank name degrades to plain "Multica".

There is no post-install rename API (bot/v3 is read-only; no
bot/v3/update), so the install-time pre-fill is the only programmatic
lever; the user can still edit the name on the creation form.

* fix(integrations/lark): restore /issue confirmation + pin SendTextMessage wire (MUL-2671)

Two recovered/added contracts off Trump's review of HEAD fe381a07:

1) /issue confirmation in Lark was a casualty of the plain-text
   refactor. The pre-refactor `RenderInput.IssueNumber` field was
   declared but never actually rendered into the card body, so even
   in the original card-based flow the user never saw a "Created
   [MUL-42]" confirmation. Now the OutcomeReplier handles
   OutcomeIngested + IssueID.Valid by sending a plain text message:

     Created MUL-42 — fix login bug
     https://multica.example/issues/MUL-42

   Composed from a new DispatchResult.IssueIdentifier +
   IssueTitle, populated by the Dispatcher from
   workspace.IssuePrefix + issue.Number / issue.Title. Workspace
   lookup is best-effort: a Postgres blip on workspace gets a "#42"
   fallback rather than silently dropping the confirmation.

   The agent's own chat reply (if any) continues to land separately
   via the Patcher on EventChatDone — these are two semantically
   distinct messages and the user benefits from seeing both.

2) SendTextMessage is the wire layer Trump flagged for missing
   coverage. Three new wire tests pin:
   - happy path: POST /open-apis/im/v1/messages?receive_id_type=chat_id,
     msg_type=text, Bearer <tenant_access_token>, double-JSON
     content envelope
   - special-character round trip: newlines, double quotes,
     backslashes, tabs, Chinese + emoji, JSON-lookalike strings.
     The inner {"text": ...} is encoded once at JSON.Marshal time
     and once again when the outer body serializes; losing either
     pass corrupts the message and the bug is invisible without a
     contract pin.
   - Lark error path: non-zero `code` surfaces as a wrapped error
     with the code embedded.

Tests:
- TestDispatcher_IssueCreationFromCommand asserts IssueIdentifier
  ("MUL-42") and IssueTitle propagate through DispatchResult.
- TestDispatcher_IssueIdentifierFallsBackToNumberOnWorkspaceLookupErr
  pins the "#7" degrade-graceful fallback.
- TestLarkOutcomeReplierIssueCreatedSendsConfirmation pins the
  text body (identifier + title + deep link) and asserts no card
  send on this path.
- TestLarkOutcomeReplierOutcomeIngestedSilentWithoutIssue pins
  the silent-on-plain-chat default so we don't accidentally start
  emitting a confirmation for every message.
- TestHTTPClient_SendTextMessage_* covers the wire contract.

Frontend locale parity (en + zh-Hans, 53 tests) is currently green
on this HEAD; no changes needed.

* fix(views/locales): add missing ko keys for Lark MVP (MUL-2671)

Trump flagged on PR #3277 review that the ko bundle was missing the
Lark-MVP-only keys that en + zh-Hans both carry. The parity test
caught it cleanly after main was merged in (Korean PR landed on main
between the prior review and this one):

  common.lark_bind.*                       (13 keys)
  settings.page.tabs.lark                  (1 key)
  settings.lark.*                          (45 keys)
  agents.inspector.section_integrations    (1 key)

Korean translations are professional/concise — "Lark" stays as the
brand name (matches how en keeps "Lark" + "(飞书)" parenthetically;
ko/users searching for the product expect "Lark"), and product copy
follows the zh-Hans tone where Multica nouns ("에이전트", "워크스페이스")
are romanized loan words consistent with the rest of the ko bundle.

Slot ordering preserved against EN:
  - page.tabs.lark sits between github and integrations
  - inspector.section_integrations sits right after section_skills

Verified: pnpm exec vitest run locales/parity → 105/105 pass.

* fix(integrations/lark): /issue origin_type CHECK + Hub restart on credentials rotation (MUL-2671)

Two live-env bugs Bohan reproduced:

1) /issue command crashed the WS connector. Dispatcher writes
   origin_type='lark_chat' on issues born from `/issue`, but the
   issue_origin_type_check CHECK constraint was last extended in
   migration 060 for quick_create — it doesn't list lark_chat, so
   every Lark /issue tripped SQLSTATE 23514 and bubbled up as an
   infra error. The infra error tore down the WS connector, Lark
   retried the same message, the new connector tripped the same
   constraint and crashed again. Repro in the live env: three
   crashes from the same /issue event over ~40s, each leaving the
   user with no confirmation in Lark.

   Migration 111 extends the CHECK list:
     CHECK (origin_type IN ('autopilot', 'quick_create', 'lark_chat'))

2) Re-scanning an already-bound agent silenced the bot. The device
   flow re-registers with Lark, which mints a brand-new bot (fresh
   app_id + app_secret); RegistrationService.finishSuccess upserts
   into lark_installation by agent_id, so the row's credentials
   rotate in place. But the running supervisor held the OLD inst
   struct by value and kept a WS open against the OLD bot's app_id —
   so all events to the NEW bot went nowhere. Bohan's "claude code
   现在不能在飞书里回复了" symptom maps exactly to this:

      log timeline:
      16:29:57  cc connector connected with app_id=cli_aa9398dd...  (OLD)
      16:34:07  lark registration: install complete                  (rotation)
      → row.app_id is now cli_aa93f36f...                            (NEW)
      → old WS still subscribed to OLD app_id; new app_id receives nothing

   Fix: Hub.sweep now compares each installation row's credentials
   fingerprint (app_id + bot_open_id + sha256(app_secret_encrypted))
   against the snapshot the running supervisor was started with. On
   diff, cancel the old supervisor and start a fresh one inline. A
   monotonic gen counter on the supervisor entry disambiguates the
   old goroutine's deferred cleanup from the new entry the rotation
   path already swapped in.

Tests:
- TestHubRestartsSupervisorOnCredentialsRotation pins the new path:
  starts hub on app_one, rotates the row to app_two, asserts the
  connector factory is called again with the fresh AppID.
- TestHubDoesNotRestartSupervisorOnUnchangedRow pins the negative
  case so an unchanged row doesn't degenerate into a per-sweep
  busy-loop.
- Existing hub tests (lease, supervise, shutdown, ACK timing,
  noop replier) all green.

Verification:
- go test ./internal/integrations/lark/... -race -count=1   ok
- go build ./... clean
- migration applied locally; \d+ issue confirms lark_chat in CHECK

* fix(integrations/lark): per-supervisor lease token to fence rotation handoff (MUL-2671)

Elon flagged a race in HEAD be8d4cef's rotation path: both the old
and the new supervisors of the same Hub used the hub-wide nodeID as
their WS lease token, so an old supervisor's post-cancel
releaseLease(nodeID) would CAS-match the lease row the successor had
just acquired with the SAME token and DELETE it. Symptom would be a
silently empty lease row a few hundred ms after every device-flow
re-scan — no replica owning the install, no events delivered, the
"bot goes quiet" pattern Bohan hit the first time but now from the
fencing side rather than the credentials side.

Fix: leaseToken(nodeID, gen) composes "<nodeID>-g<gen>", where gen is
the monotonic counter already attached to each supervisorEntry. The
nodeID prefix keeps cross-replica observability (an operator
inspecting lark_installation.ws_lease_token can still map back to a
process) while the -g suffix makes the OLD supervisor's release
target the OLD row state. Once the rotation path swaps in the new
supervisor, the row's CurrentToken is the new -g(N+1) token, so the
old -gN release's WHERE clause no-ops instead of clobbering.

acquireLease / renewLeaseUntil / releaseLease now take an explicit
token argument; supervise threads its leaseToken through. The
plumbing isn't pretty, but having an explicit argument at every call
site is the only way the rotation invariant survives subsequent
refactors — without it, a future caller could quietly reintroduce
"just use h.nodeID" and the race is back.

Two regression tests:

- TestHubRotationStaleReleaseDoesNotClearSuccessorLease drives the
  fake lease state machine directly:
    1. old acquires(tokenA)
    2. rotation lands; new acquires(tokenB)
    3. old's stale release(tokenA) fires
  Asserts owner ends up still tokenB. Hub-wide-nodeID code would fail
  step 3 by clearing the entry.

- TestHubRotationEndToEndKeepsSuccessorLeased runs the same scenario
  through the live supervise loop: starts hub, rotates the row, waits
  for sup2 to take over with a distinct token, sleeps past sup1's
  unwind, asserts the row is still held by a non-sup1 token. Catches
  the bug even when the goroutine timing is non-deterministic.

Verification: go test ./internal/integrations/lark/... -race -count=1   ok
  go build ./...                                            clean

* fix(integrations/lark): route group @-mentions via union_id, not open_id (MUL-2671)

In a Lark group with multiple Multica bots installed, the bot whose WS
received the event sometimes failed to recognize that it was the @-target
while the OTHER bot's supervisor falsely fired. Bohan's controlled three-
message test (only @A, only @B, @both) hit this: @A and @B alone went
unanswered, @both got picked up by A only.

Root cause: the `mentions[].id.open_id` field Lark puts on the WS event
is structurally INVERSE to `/bot/v3/info`'s `bot.open_id` across the two
WSes. From A's WS perspective, the wire-form open_id for "A was @-ed"
is NOT equal to A's API-side open_id, but IS equal to what B's WS sees
on its side, and vice versa. The decoder's `mention.open_id ==
inst.BotOpenID` match therefore fires on the wrong bot in multi-bot
groups. Only `union_id` (the Lark-tenant-scoped stable identifier) is
consistent across both WSes.

Changes:
- migration 112 adds nullable `lark_installation.bot_union_id`
- sqlc query exposes UpsertLarkInstallation/CreateLarkInstallation
  with bot_union_id, plus a focused SetLarkInstallationBotUnionID for
  the backfill path
- httpAPIClient.GetBotInfo now follows /bot/v3/info with /contact/v3/
  users/{open_id}?user_id_type=open_id and returns both identifiers
  on BotInfo. Soft-fails on contact-scope denial: install still
  succeeds with an empty UnionID, and the decoder falls back to the
  legacy open_id match for single-bot deployments.
- RegistrationService.finishSuccess persists union_id alongside
  open_id during the device-flow finalize.
- ws_frame_decoder.containsMention prefers union_id and only walks
  open_id when the installation row has not been backfilled yet.
- BackfillBotUnionIDs runs once at server boot for installations
  created before migration 112; bounded per-row 10s timeout and a
  pure soft-fail policy so a slow Lark round-trip cannot block
  startup.
- regression tests cover the three decoder paths: union_id match
  wins over open_id mismatch, union_id mismatch overrides open_id
  match, and open_id fallback when union_id is unknown.

* chore: drop trailing blank lines at EOF on four files (MUL-2671)

git diff --check origin/main..origin/pr-3277 flagged these as new
blank lines at EOF; clearing so the diff stays clean for review.

* fix(views/locales): add missing ja keys for Lark MVP + section_integrations (MUL-2671)

CI frontend job tripped on the ja locale parity check: ja is missing
the lark_bind block in common.json, the lark block + page.tabs.lark
in settings.json, and inspector.section_integrations in agents.json.
The ko fix earlier covered Korean; ja was added separately on main
and the merge surfaced these gaps. Translations mirror the en source
and follow the same voice as the existing ja bundle.

* fix(integrations/lark): rewrite @_user_N placeholders into clean body (MUL-2671)

When Lark dispatches a group `im.message.receive_v1`, the message
text contains opaque `@_user_1`, `@_user_2`, … placeholders and the
real identity is in `mentions[]`. We were forwarding the raw text to
the agent, so a Bohan-typed "@Bot ping test" arrived as "@_user_1
ping test" — neither human-readable nor useful as LLM context, and
the agent was paying tokens to figure out which `@_user_N` was even
itself.

The new resolveMentions pass:
  * strips the bot's own mention entirely (the dispatcher already
    routes the event on AddressedToBot; re-emitting @<self> in front
    of every message adds zero signal and pollutes context),
  * substitutes other participants with `@<displayName>` so a
    follow-up "@Alice" reads naturally,
  * collapses horizontal whitespace introduced by the strip while
    preserving original newlines.

Bot identity check uses the same union_id-preferred + open_id
fallback as containsMention, so the rewrite stays consistent with
the routing path. Tests cover the four shapes: bot self-mention,
mixed bot + other-user mention, multi-line body with stripped
mention, and a no-mention body that should be left untouched.

* fix(integrations/lark): union_id-first self mention strip + token-aware scan + local whitespace cleanup (MUL-2671)

Three review blockers on the mention rewrite from PR review:

1. isBotMention now mirrors containsMention's union_id-first policy.
   When the installation row knows our union_id, we trust it
   exclusively (open_id is structurally inverted in multi-bot
   groups — matching on it would re-introduce the routing bug we
   fixed two commits ago). open_id fallback fires only when
   union_id is absent. New tests: @-ing both bots in one message
   correctly strips only self and renders the sibling as @<name>;
   open_id-matches-but-union_id-differs does NOT strip.

2. resolveMentions no longer collapses or trims whitespace globally.
   Indentation, tabs, code blocks, tables — all preserved verbatim.
   When the self mention is removed we eat exactly one adjacent
   horizontal space (the one after the placeholder, or, when the
   mention sits at end-of-input, a single space already emitted
   right before it). New test exercises a multi-line indented +
   tabbed body and asserts the whole shape survives.

3. Prefix-collision-safe replacement. A chat with 11+ participants
   exposes both `@_user_1` and `@_user_10`; naive ReplaceAll for
   `@_user_1` would mangle the substring of `@_user_10`. The
   resolver now does a single-pass token scan with the mention
   list sorted longest-key-first, so the longer placeholder always
   wins at any scan position. New test covers the @_user_1 /
   @_user_10 case explicitly.

Also drops the temporary INFO-level diag logging the previous
commit added — root cause was confirmed (union_id swap in the
manual backfill; not a decoder bug).

* fix(integrations/lark): scope inbound dedup per (installation_id, message_id) (MUL-2671)

Root cause of the residual "@Cc gets dropped as not_addressed_in_group"
even after the union_id swap landed: lark_inbound_message_dedup was
keyed on `message_id` alone. In a Lark group chat where the workspace
has multiple Multica bots installed, Lark delivers the SAME message_id
to every bot's WS supervisor. Whichever WS claimed first then ran its
own AddressedToBot check; the bot that was actually @-ed lost the dedup
race, found the row already terminal (`processed_at IS NOT NULL`), and
was dropped as `duplicate` BEFORE it could evaluate its own mention.
Net: every @ silently disappeared if Lark happened to route the OTHER
bot's WS first.

The dedup gate's original purpose (idempotency against WS reconnect
replay) is per-installation by definition, so the right key is
composite (installation_id, message_id).

Changes:
- migration 113 drops + recreates lark_inbound_message_dedup with
  installation_id NOT NULL REFERENCES lark_installation(id) ON DELETE
  CASCADE and PRIMARY KEY (installation_id, message_id). The table is
  a 24h transient cache, so dropping existing rows is safe.
- sqlc queries: ClaimLarkInboundDedup / MarkLarkInboundDedupProcessed /
  ReleaseLarkInboundDedup all now take installation_id.
- AppendUserMessageParams carries InstallationID through to the
  in-tx Mark call so the chat_message+dedup atomicity stays intact.
- Dispatcher passes inst.ID to claim + applyFinalize + AppendUserMessage.
- Test fakes key dedup state on (installation_id, message_id) via a
  composite map key; all existing pre-seeded rows use a seedDedupKey
  helper bound to the default activeInstallation fixture so the prior
  staleness / token-rotation / in-tx mark tests still exercise the
  same regression they did before.
- New regression TestDispatcher_DedupIsScopedPerInstallation pins the
  multi-bot invariant: a row pre-seeded for installation A does NOT
  block installation B's first delivery of the same message_id; B
  runs through its own group-filter / identity / ingest pipeline.

* feat(integrations/lark): render markdown chat replies via schema-2.0 card (MUL-2671)

The agent's chat replies were going out as msg_type=text, so every
`**bold**`, fenced code block, list, table, and link in the body
showed up as literal markdown characters in Lark — the user saw raw
asterisks, hashes, pipes instead of formatted text. Bohan reported
this and pointed at zarazhangrui/lark-coding-agent-bridge as the
shape to emulate.

The bridge repo uses Lark interactive cards with the schema-2.0
envelope and a `tag: "markdown"` body element; Lark's client
renders that to formatted text (GFM-ish: bold/italic, headings,
lists, links, fenced code blocks, tables, blockquotes). They expose
multiple reply modes (card / markdown-as-post / text) gated by user
config; we go a step simpler — auto-detect markdown syntax in the
agent's body and route accordingly:

- containsMarkdown(): cheap substring + regex pass for fenced code
  blocks, headings, list markers, bold/italic, tables, links,
  blockquotes, horizontal rules, inline code. Biases toward false-
  positive — wrapping prose in a card still renders fine, but
  missing a real markdown block leaves raw characters visible.

- APIClient gains SendMarkdownCard / SendMarkdownCardParams.
  Implementation marshals the schema-2.0 envelope verbatim:
  {schema:"2.0", body:{elements:[{tag:"markdown", content: md}]}}.
  Stub returns ErrAPIClientNotConfigured.

- Patcher.sendChatReply now branches on containsMarkdown:
  markdown → SendMarkdownCard, plain prose → SendTextMessage. A
  one-liner "sure, on it" stays as a normal IM bubble (no card
  chrome); anything with markdown gets the rendered card.

Tests: TestContainsMarkdown pins the heuristic across plain prose
and ten markdown shapes; TestPatcherRoutesMarkdownReplyToCard and
TestPatcherRoutesPlainReplyToText cover the router; new HTTP wire
test TestHTTPClient_SendMarkdownCard_HappyPath contract-pins the
card envelope (msg_type=interactive, schema 2.0, markdown tag,
verbatim body). Full lark suite passes.

* fix(service/issue): route analytics.IssueCreated through obsmetrics.RecordEvent (MUL-2671)

CI's TestNoNakedAnalyticsCaptureInHandlersOrServices guard caught the
post-merge analytics call in IssueService.captureCreatedAnalytics
that still used s.Analytics.Capture(...) directly. Main added that
lint to prevent the Prometheus and PostHog sides from drifting — any
new analytics.* event must go through obsmetrics.RecordEvent so the
business-metrics collector and the PostHog client fire from the same
call site.

Fix mirrors how TaskService handles it: IssueService gains a
Metrics *obsmetrics.BusinessMetrics field (router wires it via
h.IssueService.Metrics = opts.BusinessMetrics next to the existing
TaskService line), and the in-service Capture call becomes
obsmetrics.RecordEvent(s.Analytics, s.Metrics, ...). nil-safe by
construction — RecordEvent treats a nil Metrics as PostHog-only.

* feat(views/lark): swap Bind CTA for Connected+Manage link when agent already has an installation (MUL-2671)

Bohan reported the agent-detail Bind button keeps inviting the user to
re-scan the QR even when the agent already has an active Lark
PersonalAgent connected — and re-scanning silently upserts the
installation row, leaving the previously-created Lark bot dangling
as a zombie. Frustrating UX and an actual product footgun.

Anti-zombie guard at the only entry point: LarkAgentBindButton now
checks the cached installations listing for an active row pinned to
this agent_id. When one exists, the install CTA is gone — replaced
by a small Connected pill + an "Manage in Lark" link that opens the
Bot's app page in Lark's developer console (open.feishu.cn/app/<app_id>)
in a new tab. That's where scopes, display name, and additional
permission requests actually live; re-scanning never was the right
answer for managing an existing bot.

Scoping is per-agent: an active installation on a DIFFERENT agent
in the same workspace doesn't affect this agent's button, and a
revoked installation falls back to the bind CTA so the user can
re-create. Tests cover all four states (own-active / own-revoked /
other-agent-active / no-installation) and pin the Manage link's
href + target=_blank + noopener.

i18n: three new keys in settings.json (en / zh-Hans / ja / ko):
agent_bot_connected_label, agent_bot_manage_link,
agent_bot_manage_tooltip. Locale parity test still 157/157.

The dev console host is hardcoded to open.feishu.cn — operators
on the Lark international tenant currently get the wrong host;
future-proof fix wants the backend to surface a per-installation
dev_console_url on the listings response, called out in a code
comment.

* feat(views/settings): collapse Lark into Integrations + render agent identity (MUL-2671)

Lark was its own top-level workspace settings tab while Integrations sat
empty next to it. As more integrations land, the sidebar would balloon
with one tab per provider. Move the Lark surface into Integrations as
the first hosted integration; the old ?tab=lark URL redirects through
LEGACY_WORKSPACE_TAB_REDIRECTS so bookmarks still resolve.

The Connected bots list was leaking the raw Lark app_id (cli_…) as the
row title with bot_open_id (ou_…) underneath — meaningless to product
users. Since the binding is 1:1 with a Multica Agent, join on agent_id
and render the agent's avatar + name via the workspace-standard
ActorAvatar + useActorName.getAgentName. Deleted agents fall back to
"Unknown Agent" so the row is still actionable for cleanup.

Tests: stub useActorName + ActorAvatar in lark-tab.test.tsx and add
LarkTab connected-bot tests covering the agent identity render and the
deleted-agent fallback. Drop the now-dead integrations.* + page.tabs.lark
+ lark.bot_open_id_label keys across all four locales — parity still
157/157, views suite 1141/1141.

* feat(views/settings): wrap Lark in a named section inside Integrations (MUL-2671)

Integrations is meant to host multiple providers (Slack, Linear etc. as
they land), so the Lark content should sit under a Lark heading rather
than fill the tab directly — otherwise the first additional integration
would feel like it broke the IA. Add a "Lark" / "飞书" section heading
above LarkTab using the same h2 chrome the other settings tabs use, and
pin lark.section_title across all four locales (parity 169/169).
