b92c3fbc93 chore(analytics): stop shipping operational events to PostHog (MUL-2967) (#3720)
* chore(analytics): stop shipping operational events to PostHog (MUL-2967)

Operational / execution-lifecycle telemetry dominated PostHog event volume
and drove the bill: runtime_offline alone was ~54% of ~22.6M events/mo, and
~99% of events were billed at the higher identified-event rate. These signals
already have Prometheus counters (Grafana), so the PostHog copies were
redundant cost.

- Add analytics.IsMetricsOnly; metrics.RecordEvent now skips the PostHog
  Capture for runtime_* and autopilot_run_* while still incrementing their
  Prometheus counter (their analytics.Event constructors are retained to feed
  the metric label set via IncForEvent).
- Remove the agent_task_* PostHog path entirely: drop captureTaskEvent and the
  AgentTask* constructors/constants. Their Prometheus side is unchanged via the
  typed BusinessMetrics.RecordTask* methods. Also remove the now-dead
  taskDurationMS / willRetryTask helpers.
- Update the pairing lint test (no agent_task allow-list, no naked-Capture
  exception), add a RecordEvent skip test + IsMetricsOnly test, and update
  docs/analytics.md (taxonomy, per-event banners, reconciliation).

Product/funnel events (signup, onboarding, issue_created, issue_executed,
chat_message_sent, agent_created, autopilot_created, etc.) are unchanged and
still ship to PostHog.

* docs(analytics): correct agent_task Prometheus metric contract (MUL-2967)

Address PR review: the agent_task_* "Prometheus-only" banner claimed the old
PostHog event properties (task_id, agent_id, duration_ms, error_type,
will_retry, ...) were the metric label set. They are not — the real labels are
only source/runtime_mode/provider/terminal_status/failure_reason.

- Replace the agent_task_* sections with the actual metric names and labels
  (multica_agent_task_*; see business.go / labels.go), and explain that
  completed/failed/cancelled are terminal_status values on
  multica_agent_task_terminal_total, with wall-clock in the *_seconds
  histograms.
- Tighten the runtime_*/autopilot_run_* banners so id properties aren't
  mistaken for labels.
- Drop the stale AgentTask allow-list reference from the pairing lint test
  header comment.

6330286c7e fix(lark): use named import for react-qr-code to survive electron-vite interop (#3718)
* fix(lark): use named import for react-qr-code to survive electron-vite interop

Clicking Bind on the agent detail page white-screened the desktop app at
the QR step:

  Element type is invalid: expected a string or a class/function but got:
  object. Check the render method of `LarkInstallDialog`.

react-qr-code is a CJS package. `import QRCode from "react-qr-code"`
relies on the bundler's __esModule default-interop to unwrap `.default`.
Next.js (web) unwraps it correctly; electron-vite's dep-optimizer handed
back the whole module namespace object `{ default, QRCode, __esModule }`
instead of the component, so React got an object where it expected a
component the moment <QRCode> mounted — desktop-only white screen, web
unaffected.

Switch to the named import `{ QRCode }`, which maps straight to
`exports.QRCode` and doesn't depend on the flaky default-interop path.
Resolves correctly under both bundlers; the package's own .d.ts exports
both the named class and the default, so it typechecks unchanged.

Not a backend / Lark-config issue — purely a frontend CJS interop bug.

* test(lark): expose named QRCode export in react-qr-code mock

Follow-up to the named-import switch in lark-tab. The test stubbed
react-qr-code with only a `default` export; now that the component
imports `{ QRCode }`, the named binding resolved to undefined and the
3 QR-rendering tests failed with "No QRCode export is defined on the
react-qr-code mock". Return the stub as both `QRCode` and `default`,
defined inside the factory (vi.mock is hoisted above top-level vars).

598a6c51f2 refactor(server/lark): collapse HTTP_ENABLED + WS_ENABLED into the SECRET_KEY gate (MUL-2671) (#3717)
MULTICA_LARK_HTTP_ENABLED and MULTICA_LARK_WS_ENABLED were staging
knobs from the multi-PR rollout of the Lark MVP — they let the DB
schema + inbound dispatcher land before the HTTP wire was real, and
before the WS long-conn protocol was wired. Now that the MVP has
shipped end-to-end, "I set SECRET_KEY but I don't want to talk to
Lark" is not a useful production state: setting the at-rest master
key is the operator's opt-in for the integration as a whole.

Collapse the gate down to MULTICA_LARK_SECRET_KEY alone. When the
key is present, wire the real HTTPAPIClient + the real
WSLongConnConnector. CI / integration tests that want stub-style
behaviour can point MULTICA_LARK_HTTP_BASE_URL at a mock server
(already supported) instead of toggling a separate flag. Host
overrides (HTTP_BASE_URL, REGISTRATION_DOMAIN, CALLBACK_BASE_URL)
stay — those are real ops needs for international tenants / staging.

stubAPIClient + NoopConnectorFactory remain exported because the
test suite uses them directly; only the router boot path stops
reaching for them. The connector factory keeps its noop fallback
for the case where the endpoint fetcher fails to construct, so a
malformed MULTICA_LARK_CALLBACK_BASE_URL degrades gracefully
(visible as "connector=noop" in the boot log) instead of panicking
the server.

Lark integration + handler tests still pass; go vet clean.

d6a556bdbf fix(execenv): refresh skills in place on reuse instead of accumulating duplicate dirs (#3716)
Re-dispatching the same agent on the same issue reuses the persistent workdir
via execenv.Reuse(), where the standard-provider skill refresh re-wrote skills
without clearing the prior dispatch's output, so allocateCollisionFreeSkillDir
dodged Multica's own directories into issue-review-multica-N.

On reuse, reclaim the platform-owned managed skill directories the prior
manifest recorded (removeReusedManagedSkillDirs) and roll back the remaining
sidecar files (CleanupSidecars) before refreshing, so each skill lands at its
canonical slug every dispatch. Mirrors the Codex hydrateCodexSkills wipe;
scoped to reuse, which never runs for local_directory tasks.

Fixes #3684 (MUL-2963).

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.

* 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`).

* ci: re-trigger workflow on lark MVP must-fix HEAD (retry)

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

* 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
  go vet ./...                                              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.

* 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).

1544e3b68a feat(skills): built-in agent skills (WIP) MUL-2759 (#3456)
* feat(skills): introduce built-in agent skills (WIP)

Inject platform-authored, version-bundled skills into every agent on top of
its workspace-bound skills, so agents learn how to operate Multica correctly
without users needing to know the internals or agents needing to read source.

Mechanism: skills are embedded into the server binary and appended to the
agent payload at task-claim time (handler/daemon.go), reusing the existing
SkillData wire + daemon-side writeSkillFiles. The daemon needs no changes,
and because it travels over an existing wire field, older daemons pick the
skills up the moment the server ships.

First skill: multica-mentioning — how to build a working @mention (look up
the UUID, match type to id source, know what each mention type triggers).

WIP: injection mechanism + first skill only; more skills to follow in
dependency order (skill -> agent -> squad).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(skills): make multica-mentioning the standard template + add eval

Add the contract-skill frontmatter the other built-in skills will copy:
user-invocable:false (it triggers from context, not as a slash command)
and allowed-tools fencing it to the multica CLI it teaches. These keys
survive to agent machines untouched (ensureSkillFrontmatter only ever
adds a missing name).

Add a Go eval in builtin_skills_test.go (a _test.go so it never ships to
agent machines via the skill-files walk):
- Enforces the template invariants on every built-in skill, present and
  future: multica- prefix, name+description present, description within
  1024 chars, body within the 500-line L2 budget, no eval file leaking
  into the shipped payload.
- Couples the mentioning skill's documented contract to the real
  util.ParseMentions: its Incorrect examples must parse to nothing (a
  name where a UUID belongs fails silently) and its Correct example must
  fire. A drift in the mention regex now breaks CI instead of silently
  turning the skill into a lie agents act on.

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

* refactor(skills): rewrite built-in skills as source-traced contracts

Rewrite the built-in agent skills to the inbuilt-skill-authoring standard:
state source-traced product facts with the source-code link logic as the
core, not prescriptive how-to coaching.

- creating-agents: drop the Decision-flow / Do-don't-consequences
  methodology; replace with field/behavior contracts (validation, persisted
  shape, daemon claim-time consumption, env gating, skill binding).
- skill-discovery: stop teaching repo/github_stars as selection signals —
  searchClawHubSkills never populates them (always null); rank by
  install_count + source/url + description. Add file:line citations.
- mentioning: drop the unbacked "member mention sends a notification" claim
  (no such path in the comment handler); state that only agent/squad
  mentions enqueue work. Tighten the parser-failure wording.
- working-on-issues: refresh citations drifted by the main merge; describe
  the PR response `state` enum accurately; trim status coaching.
- skill-importing: correct response type to SkillWithFilesResponse; document
  the reserved SKILL.md supporting-file rule; add line-accurate citations.
- squads: correct the "leader cannot be archived" overstatement (not
  rejected at create/update; fails closed later at routing/dispatch);
  refresh source-map attributions and test list.

Each skill now ships references/<skill>-source-map.md as its evidence layer
(line-accurate citations live there, not pinned in the test, so a future
main merge cannot rot them into stale lies).

builtin_skills_test.go: replace coaching/line-number pins with drift-resistant
contract anchors, forbid the coaching phrasing, and require every skill to
ship its source-map. The ParseMentions behavior coupling is preserved.

* docs(skills): close field-role and citation gaps found in review

Independent review of the rewritten built-in skills surfaced two real gaps and
some citation drift; this fixes them.

- creating-agents: add the three missing field rows (visibility,
  max_concurrent_tasks, mcp_config) to the field-contract table — mcp_config is
  runtime-consumed (TaskAgentData, daemon.go), visibility is access-control
  (default private), max_concurrent_tasks is a scheduler cap (default 6).
  Mark custom_args/runtime_config JSON validation as CLI-side (the server
  marshals as-is). Correct the CLI body-builder note (description/instructions
  use a non-empty check, the rest use Changed). Source-map: fix the env query
  name (UpdateAgentCustomEnv), the conformance test name, and add the new field
  defaults + the McpConfig runtime-payload line.
- mentioning: the @squad mention private gate is canAccessPrivateAgent, not
  canEnqueueSquadLeader (that wrapper is the assignment/child-done path).
- working-on-issues: cite notifyParentOfChildDone at its func def (:51), not the
  doc comment (:15).
- skill-importing: config.origin is set only when the source supplied an origin
  — note it may be absent; cite createSkillWithFiles at its definition
  (skill_create.go:72), not the call site.

* Add built-in skills for autopilots runtimes and resources

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

* feat(runtime): list skill descriptions in the brief Skills index

The brief's `## Skills` section emitted bare skill names only, discarding
the one-line description that SkillContextForEnv already carries. For
Claude-family providers the frontmatter description is loaded natively;
for providers without native skill discovery (hermes/default) the brief's
list is the only signal they ever see, so a bare name gave them nothing
to decide when to load a skill. Emit `name — description` when a
description is present, falling back to the bare name when it is empty.

* refactor(skills): drop CLI-only rule from working-on-issues

The "Platform data goes through the CLI" section duplicated the runtime
brief's `## Important: Always Use the multica CLI` section verbatim (and
the attachment-via-CLI note duplicated the brief's `## Attachments`). The
CLI-only rule is universal and must be known before any skill loads, so
the brief is its single source of truth; the skill copy was pure
redundancy and a drift risk. Remove it and the matching intro clause.

* refactor(skills): remove discovery guidance from built-ins

* docs(skills): remove stale skill-necessity records

The per-skill necessity records had drifted to 3 of 8 shipped skills plus a
record for `multica-skill-authoring`, which is not a shipped built-in skill.
Per-skill "why it exists / when to use it" already lives co-located with each
skill (frontmatter `description` + `references/<skill>-source-map.md`) where it
cannot drift from the skill, and the doc's methodology duplicated the
workspace's inbuilt-skill-authoring protocol. Remove the file rather than keep a
parallel listing that every new skill has to remember to update.

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

* feat(runtime): add source-authority escape hatch to the brief

The brief already tells agents to run `--help` for command discovery, but
nothing stated the trust precedence when a skill, the brief, or a doc seems to
contradict actual behavior. Add one line to the Available Commands escape-hatch
note: trust the live CLI (`--help`/`--output json`) and the checked-out source
over source-traced prose that can lag the code, and verify on any conflict or
confusion. Kept in the always-on brief (universal, needed before any skill
loads) rather than duplicated into each skill; per-skill source-map pointers
remain the specific layer.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Co-authored-by: multica-agent <github@multica.ai>

* fix(runtime): scope the source-authority escape hatch to the CLI

The previous version told agents the "checked-out source is the deeper
authority" for verifying behavior. That over-claims: the repos in a task's
brief come from GetWorkspaceRepos + project github_repo resources (per-workspace
config, see daemon.registerTaskRepos), not the Multica platform source. A
generic agent's checked-out source is its own app, not Multica's code, so it
cannot verify a Multica skill/brief claim against it. The only universally
available authority for Multica behavior is the live CLI (`--help` /
`--output json` / observed command behavior). Re-scope the line accordingly and
state plainly that the platform's source is not in the workdir.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Co-authored-by: multica-agent <github@multica.ai>

* revert(runtime): drop the source-authority escape-hatch line

Reverts the brief addition from fdd5e82df and its follow-up cc67b2088. The
`--help` discovery fallback already in the Available Commands note is enough;
the extra trust-precedence sentence was unnecessary. runtime_config.go is now
identical to 6ca27ad74.

* docs(claude): remind to update built-in skills on CLI/field/behavior changes

Add a Coding Rule: when a change touches a CLI command/flag, API field, or
product behavior that a built-in skill documents, update that skill's SKILL.md
and source-map in the same PR. Lives in the repo dev-guide (read when working in
this repo), not the runtime brief — the runtime brief is injected into every
workspace, where most agents have no Multica skill to update. AGENTS.md is a
pointer to CLAUDE.md, so no mirror needed.

9c9afd4a66 feat(metrics): BusinessSamplerCollector for active users / queued / runtime gauges (MUL-2947) (#3706)
* feat(metrics): scrape-time BusinessSamplerCollector for active users / queued / runtime gauges (MUL-2947)

Adds an opt-in prometheus.Collector that runs a fixed set of read-only
SQL queries on every /metrics scrape and exposes the results as gauges:

  - multica_active_users{window=5m|1h|24h}
  - multica_active_workspaces{window=...}
  - multica_agent_task_queued{source}
  - multica_agent_task_running{source,runtime_mode}
  - multica_agent_task_stuck_total{source}
  - multica_runtime_online{runtime_mode,provider}
  - multica_runtime_heartbeat_age_seconds{runtime_mode} (histogram)
  - multica_workspace_total

Plus a self-introspection histogram
multica_business_sampler_query_seconds{name=...} and a counter
multica_business_sampler_query_errors_total{name=...} so the sampler's
own behaviour is observable on /metrics.

Production-safety contract per the PR4 brief:
  - every query runs in its own BEGIN READ ONLY tx with
    SET LOCAL statement_timeout = '500ms' (configurable)
  - the sampler takes a dedicated *pgxpool.Pool option so operators
    can isolate it from business traffic
  - successful results are cached for 5–10s (default 8s) to absorb
    concurrent scrapes from multiple Prometheus replicas
  - every SQL has a hard LIMIT 100 fallback
  - all label values flow through the existing BusinessMetrics
    NormalizeTaskSource / NormalizeRuntimeMode / NormalizeRuntimeProvider
    whitelists, so a misbehaving runtime cannot inflate cardinality
  - sampler is OPT-IN via RegistryOptions.BusinessSampler — existing
    callers that only pass Pool keep their current behaviour and never
    start hitting the DB on /metrics

Tests cover: emit shape, TTL cache (one DB call per N scrapes),
bounded cardinality under malicious labels, opt-out (no leakage), and
DB-hang isolation (unreachable host -> /metrics returns within 5s,
query_errors_total advances).

Refs MUL-2947 (depends on PR2 / MUL-2948, merged in #3695).

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

* fix(metrics): address PR4 review — wire sampler in main.go, fix LIMIT bug, add live-DB statement_timeout test

Three fixes from 大彪's review on #3706:

1. main.go was building NewRegistry without the BusinessSampler option,
   so the collector was effectively dead code in prod. Now constructs a
   dedicated 2-conn pgxpool (newSamplerDBPool) from the same DATABASE_URL
   when METRICS_ADDR is set, plumbs it into RegistryOptions.BusinessSampler,
   and defers Close() at shutdown. A pool-build failure logs and disables
   the sampler instead of taking down the server.

2. queryActiveUsers / queryActiveWorkspaces previously wrapped the
   distinct-user/workspace subquery in a 'LIMIT 100', then COUNT(*)'d
   the result — capping the active-user gauge at 100 regardless of
   reality. Removed the inner LIMIT; the COUNT scalar is one row anyway,
   and metric cardinality is bounded by the fixed samplerWindows
   allow-list, not by the SQL shape.

3. The previous DB-hang test only exercised the acquire-fails path. Added
   business_sampler_pgsleep_test.go which connects to a live Postgres
   (skips cleanly when DATABASE_URL is not set), runs SELECT pg_sleep(2)
   inside a sampler-style tx with SET LOCAL statement_timeout = '500ms',
   and asserts:
     - the call returns in well under 1.5 s (proving the server-side
       cancellation, not just our caller-side context)
     - query_errors_total{name=pg_sleep_canary} advances
     - the duration histogram records the cancellation
   Verified locally: 550 ms, SQLSTATE 57014 'canceling statement due to
   statement timeout' — exactly the safety net the PR claims.

Refs MUL-2947 / PR #3706.

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

* test(metrics): assert SQLSTATE 57014 on pg_sleep cancellation

The previous assertion only checked that the query was cut off in well
under the sleep duration, which a caller-side context cancellation
would also satisfy. Capturing the inner pgconn.PgError and asserting
Code == "57014" ("query_canceled") nails down that Postgres itself
cancelled the statement because of the SET LOCAL statement_timeout —
so a regression that drops the SET LOCAL line fails this test loudly
instead of silently passing on context cancellation.

Refs MUL-2947 / PR #3706 review nit.

a8776095bc docs(self-hosting): document WebSocket Origin allowlist requirement (#3704)

but not the backend's Origin allowlist, which rejects WS upgrades from
non-localhost origins with a 403 (websocket: request origin not allowed
by Upgrader.CheckOrigin) unless CORS_ALLOWED_ORIGINS / FRONTEND_ORIGIN is
set to the external origin. Self-hosters hit this as "chat / live updates
only appear after a manual page refresh" (#3677).

- Note CORS_ALLOWED_ORIGINS governs both HTTP CORS and the WS origin check
- Add the env-var requirement to the single-domain Caddy example
- Add an "allowlist the browser origin" callout to the WebSocket

The pairing helper metrics.RecordEvent(client, m, ev) emits the PostHog
event AND increments the matching counter via IncForEvent dispatch, reading
labels from the analytics event Properties. Every existing
h.Analytics.Capture(analytics.X(...)) call site has been migrated to the
helper across handler/, service/, and cmd/server/runtime_sweeper.go.

Lint enforcement (server/internal/metrics/business_pairing_test.go):
- TestEveryAnalyticsEventHasPrometheusCounter: every Event* constant in
  analytics/events.go either dispatches via IncForEvent or is in the
  taskMetricEvents allow-list (PR2 typed RecordTask* methods).
- TestNoNakedAnalyticsCaptureInHandlersOrServices: AST-walks handler/
  service/cmd-server for direct Analytics.Capture(...) calls — only
  service/task.go's captureTaskEvent helper is allow-listed.
- TestEveryAnalyticsRecordEventTakesAnalyticsHelper: validates the third
  arg of every metrics.RecordEvent call is built from analytics.*.

Cardinality protection: all new label values pass through fixed allow-lists
in labels_pr3.go; unknown values collapse to 'other'/'unknown'/'error'.

Refs:
- Spec MUL-2328 / MUL-2949.
- Builds on PR2 (MUL-2948) — collectors registered through the same
  BusinessMetrics struct, no separate Registry.
- Uses PR1's taskfailure.Reason (MUL-2946) for runtime_failed's failure_reason
  label via NormalizeFailureReason.

Out of scope: Sampler-class metrics (PR4 / MUL-2947), pr_review_total
emission point (no review event handler exists yet — counter is defined,
TODO to wire up when /api/webhooks/github grows pull_request_review handling).

* fix(server): tighten PR3 review items — signup_source bucket, fill platform/kind/form_source enums, onboarding_started server emission, lint scope (MUL-2949)

Addresses 张大彪's review on #3698:

1. signup_source: NormalizeSignupSource added to labels_pr3.go with a
   fixed allow-list bucket (direct/google/twitter/linkedin/.../other).
   Parses JSON cookie payload for utm_source/source/referrer fields,
   strips URL schemes, maps well-known hostnames to channel buckets.
   PostHog event still ships the raw cookie value for analytics; only
   the Prometheus label is bucketed.

2. Filled the unknown/other label gaps:
   - analytics.IssueCreated and analytics.ChatMessageSent now take a
     platform parameter sourced from middleware.ClientMetadataFromContext
     (X-Client-Platform header) at the handler. Autopilot-originated
     issues stamp PlatformServer.
   - analytics.FeedbackSubmitted now takes a kind parameter; CreateFeedback
     reads req.Kind (default "general") so the picker selection lights up
     the metric's kind label instead of long-term "other".
   - analytics.ContactSalesSubmitted now takes a formSource (page /
     onboarding / agents_page); CreateContactSales reads req.Source.
     The metric reads ev.Properties["form_source"] so the analytics
     CoreProperties.Source ("marketing_contact_sales") stays
     backward-compat for PostHog dashboards.

3. analytics.OnboardingStarted helper added; server-side emission lives
   in PatchOnboarding, fired exactly once per user on the first PATCH
   that carries a non-empty questionnaire payload (firstTouch logic
   compares prior bytes against {} / null). Frontend onboarding_started
   keeps firing on page open; the server emission is what guarantees the
   Prometheus counter exists so Grafana can be cross-checked against the
   PostHog funnel without depending on the SDK roundtrip.

4. business_pairing_test.go tightened:
   - TestNoNakedAnalyticsCaptureInHandlersOrServices now allow-lists at
     function granularity (just captureTaskEvent in service/task.go), not
     whole-file. Any future naked Capture in the same file fails CI.
   - TestEveryAnalyticsRecordEventTakesAnalyticsHelper now does def-use
     tracking inside the enclosing FuncDecl: when RecordEvent's third
     arg is an *ast.Ident, the test walks the function body for the
     assignment that defined it and confirms the RHS is an
     analytics.<Helper>(...) call. Bare local idents that didn't
     originate from analytics are now caught.

5. gofmt -w applied across the touched files; gofmt -l clean.

Tests: go test ./internal/metrics/... ./internal/analytics/... pass.
Pre-existing TestClaimTask_/TestWebhook_MergedPR/TestDeleteIssueByIdentifier
failures on origin/main are DB-environment-dependent and not regressions
from this change.

* fix(server): normalise onboarding_started platform label + regression test (MUL-2949)

Addresses 张大彪's last review nit:

- IncForEvent's EventOnboardingStarted case now wraps the platform
  property with NormalizePlatform, matching every other platform-bearing
  metric. A misbehaving frontend can no longer leak a raw X-Client-Platform
  header value into the multica_onboarding_started_total{platform=...}
  series.

- New labels_pr3_test.go covers every PR3 normalizer with both a happy-path
  value and an unknown value, asserting the unknown collapses to the
  documented fallback bucket. Includes a focused regression for
  onboarding_started: emits one event with an attacker-shaped platform
  string and asserts the metric only exposes web + unknown label values
  (no raw header bleed).

- testutil.go gains a small GatherForTest helper so the regression test
  can pull the typed MetricFamily map without re-implementing the
  registry-walk dance.

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

* fix(server): NormalizeTaskSource on workspace_created + document lint limitations (MUL-2949)

Final review touch-ups before merge:

- IncForEvent's EventWorkspaceCreated case wraps source through
  NormalizeTaskSource, matching the other source-bearing dispatches
  (issue_created, agent_created, issue_executed). Closes the last raw
  property leak in the dispatcher table.

- business_pairing_test.go inline docstrings now spell out the two
  known limitations of the lint gate that 张大彪 / Eve flagged:
  analyticsBackedIdents matches by ident NAME (not SSA def-use, so a
  nested-scope shadow could pass) and isMetricsRecordEvent hard-codes
  the import alias set. PR description carries a Follow-ups section
  with the same two items so the work is visible after merge.

24ea169d89 fix(migrate): serialize startup migrations with pg advisory lock (#3658)
cmd/migrate previously ran a check-then-apply loop on a *pgxpool.Pool
with no locking, so two backend pods starting at the same time (multi-
replica Deployment, scale-up, or a manual run overlapping with pod
startup) could both pass the EXISTS check on a pending migration and
race on the DDL or the schema_migrations INSERT, crashing the loser.

Take a single connection from the pool, hold a session-level
pg_advisory_lock for the entire migration loop, and release it on the
way out. We use the blocking variant so a late arriver queues behind
the current runner and then no-ops on the EXISTS checks instead of
crash-looping. The loop deliberately stays outside a transaction so
existing CREATE INDEX CONCURRENTLY migrations keep working.

Also refresh the values.yaml / backend.yaml comments next to
backend.replicas: the chart still ships replicas: 1 by default, but
that is now a recommendation (Recreate strategy, no leader split), not
a correctness requirement.

5900d8b637 fix(issues): make start_date/due_date timezone-stable calendar days (#3618) (#3692)
* fix(issues): store start_date/due_date as DATE, not timestamp (MUL-2925)

These fields are calendar days (the pickers offer no time-of-day), but were
stored as TIMESTAMPTZ. A client serializing local midnight via toISOString()
folded its timezone into the instant, so the day shifted by the local offset
(GH #3618). Migrate the columns to DATE and parse/serialize date-only
"YYYY-MM-DD". ParseCalendarDate still accepts legacy RFC3339 (truncated to the
UTC day) so older clients keep working.

* fix(issues): render start_date/due_date as timezone-stable calendar days (MUL-2925)

Pickers now emit date-only "YYYY-MM-DD" (local calendar day) instead of
toISOString(), and every read formats via the shared @multica/core/issues/date
helpers with timeZone:"UTC" so the day never shifts with the viewer's offset.
The Gantt's existing UTC bucketing is now correct. Covers web/desktop pickers,
quick-set menu, list/board/detail/activity, and the mobile due-date picker.

* fix(issues): address date-only review — loud-fail ambiguous dates, finish display sweep (MUL-2925)

Review follow-ups on #3692:
- ParseCalendarDate no longer silently truncates a legacy non-midnight RFC3339
  to the wrong UTC day; it accepts only YYYY-MM-DD or an exact UTC-midnight
  instant and rejects ambiguous ones loudly. Adds util unit tests.
- migration 112 pins the TIMESTAMPTZ->DATE conversion to UTC explicitly via
  AT TIME ZONE 'UTC' (was session-timezone dependent); down migration too.
- Convert remaining date-change display sites to formatDateOnly: inbox detail
  label (web) and mobile activity + inbox labels (were new Date()+local format).
- CLI --start-date/--due-date help now says YYYY-MM-DD, not RFC3339.

10afd1af1b feat(server): introduce pkg/taskfailure classifier and switch in-flight failure_reason writes (MUL-2946) (#3693)
Lift MUL-1949's offline backfill failure_reason taxonomy into a shared
in-flight classifier so the agent_task_queue.failure_reason column is
written with refined values (provider_auth_or_access, context_overflow,
provider_capacity_or_rate_limit, …) at write time rather than waiting on
SQL backfill to re-classify after the fact. PR1 of the Grafana board
plan in MUL-2328 — the upcoming PR2 reuses pkg/taskfailure.AllReasons()
to pre-warm the Prometheus failure_reason label set.

* server/pkg/taskfailure: new package with the canonical 21 Reason
  constants (7 platform-side + 14 agent_error.* sub-reasons),
  AllReasons() returning a defensive copy, IsAgentError() prefix check,
  and Classify(rawError) Reason mirroring the SQL CASE rules from
  MUL-1949 (db-boy's analysis). 100% statement coverage.
* server/internal/daemon/daemon.go: route the 'agent_error' coarse
  fallback paths (StartTask error, runTask early-return error, CompleteTask
  permanent rejection, reportTaskResult default branch) and the
  executeAndDrain default error case (chained after classifyPoisonedError)
  through taskfailure.Classify so blocked / timeout / unknown-status
  results all carry a refined reason on the wire.
* server/internal/service/task.go: FailTask classifies errMsg when the
  daemon-supplied failureReason is empty, eliminating the legacy
  COALESCE(.., 'agent_error') landing.
* server/internal/daemon/poisoned.go: alias FailureReasonIterationLimit
  and FailureReasonAPIInvalidRequest to the canonical taskfailure
  constants. agent_fallback_message and codex_semantic_inactivity are
  pre-existing operational reasons not in the canonical 21 — kept as
  literals for now and revisited in a follow-up PR.

Backfill SQL from MUL-1949 stays as the authoritative offline source of
truth; this PR keeps the in-flight classifier in lock-step with the SQL
CASE expression so historical and future rows share the same taxonomy.
No behavior change for the platform-side reasons (queued_expired,
runtime_offline, runtime_recovery, timeout, etc.) which already align
with the canonical set.

Deployment-order compatibility: a backend deployed before the

The cursorless initial page now falls back to the legacy full-list
/messages endpoint and wraps it in a single has_more:false page, so
chat never white-screens regardless of which side deploys first. A 404
on a cursor request still propagates to avoid duplicating the full list.

Newer opencode (1.15+) syncs its hosted free-model catalog over the
network on `opencode models`, which can take ~6s. The previous 5s cap
killed the command, discoverOpenCodeModels returned an empty list, and
the daemon reported it as a successful empty result — so the runtime

0d51614c9c feat(editor): text highlight (==text==) in description & comments [MUL-2934] (#3661)
* feat(editor): support text highlight (==text==) in description & comments

Adds a single-color (yellow) text highlight mark to the shared rich-text
editor, round-tripped through stored Markdown as ==text==.

- HighlightExtension: @tiptap/extension-highlight + @tiptap/markdown hooks
  (markdownTokenizer/parseMarkdown/renderMarkdown) so ==text== <-> <mark>
  round-trips; inner inline formatting preserved via inlineTokens.
- Bubble menu: highlight toggle button (Mod-Shift-H), i18n in 4 locales.
- Read-only renderer: highlightToHtml lowers ==text== -> <mark> (skips code
  and math); rehype-sanitize schema whitelists <mark>. Nested Markdown inside
  a highlight still parses via the existing rehype-raw step.
- prose.css: single yellow <mark> style, legible in light/dark.

Pinned @tiptap/extension-highlight to exact 3.22.1 to match @tiptap/core
(>=3.23 expects a getStyleProperty export core 3.22.1 doesn't have).

Web/desktop only. Mobile (native md4c, no == syntax, no custom renderers)
is tracked as a follow-up. MUL-2934.

Tests: editor round-trip (cross-process serialization protocol), readonly
<mark> rendering + sanitize, and the ==->mark transform incl. code-skip.

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

* fix(editor): align highlight boundary rules across editor & readonly

Addresses two boundary bugs from review (PR #3661):

1. A == inside inline code/math could close a highlight when the opening
   == was outside the literal span (e.g. ==a `b==c` d== wrongly became
   <mark>a `b</mark>c` d==). Both the editor tokenizer's lazy regex and the
   readonly transform only guarded the opening fence, not the closing one.
2. The readonly transform matched across blank lines (==a\n\nb==) while the
   editor lexes those as two literal paragraphs — a storage↔editor↔readonly
   mismatch.

Fix: extract one shared matcher (utils/highlight-match.ts) used by BOTH the
editor tokenizer and the readonly lowering, so the rules can't drift. It skips
fences that fall inside code/math literal ranges (open or close) and caps the
inner span at the first blank line.

Tests: shared-matcher unit tests + both repros covered on the editor
(round-trip/HTML) and readonly (transform + rendered DOM) sides.

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

* fix(editor): handle CRLF in highlight blank-line boundary

BLANK_LINE_RE only matched LF, so a CRLF blank line (==a\r\n\r\nb==) was not
recognized as a block boundary and got highlighted. Widen to \r?\n[ \t]*\r?\n.

Tests: CRLF blank-line (no highlight) + CRLF soft-break (still highlights) on
the matcher, readonly transform, and editor sides.

44feb3d06d fix(skill): canonicalize reserved SKILL.md path check across daemon + API (#3660)
A skill_file row whose path is the skill's own SKILL.md (persisted by
older builds or direct create/update API calls) collides with the
primary content the daemon writes itself, failing task prep with
errPathPreExists on every non-codex local runtime (#3489).

#3526 guarded this with strings.EqualFold(path, "SKILL.md") at the
daemon write site and the three API ingress points, but the stored path
is not canonicalized: "./SKILL.md" or "sub/../SKILL.md" slip past the
exact-match guard while filepath.Join still resolves them onto the same
SKILL.md, so prep can still break.

Extract one canonical helper, skill.IsReservedContentPath, that cleans
the path before the case-insensitive compare, and use it at all four
sites (execenv writeSkillFiles, skill create, update, single-file
upsert). Add a daemon-side regression test for writeSkillFiles ignoring
a bundled SKILL.md (exact + "./" spellings) — the load-bearing fix
previously had only API-layer coverage — plus a unit test for the helper.

Existing poisoned rows are intentionally left in place (skipped at prep)
per the decision on MUL-2928.

888186b183 fix(daemon): make comment-posting guardrail provider-agnostic (MUL-2904) (#3654)
* fix(daemon): make comment-posting guardrail provider-agnostic (MUL-2904)

Agents inlining a backtick-wrapped token into `multica issue comment add
--content "..."` had the shell run it as a command substitution, silently
deleting the token; the stored comment never matched the model's intent, so
it retried forever — spamming OKK-497 with duplicate comments.

The corruption is shell-driven, not provider-driven, so extend the
"never inline --content; use --content-file / quoted-HEREDOC --content-stdin"
rule from Codex-only to ALL providers:

- BuildCommentReplyInstructions: collapse the Linux/macOS non-Codex inline
  branch into the unified quoted-HEREDOC stdin template.
- buildMetaSkillContent: rename "Codex-Specific Comment Formatting" ->
  "Comment Formatting" and emit it for every provider; strengthen the
  Available Commands entry and the assignment step-6 examples to steer away
  from inline --content.
- Windows behavior unchanged (file-only; avoids PowerShell ASCII drop).

Tests: flip the non-Codex Linux reply test into a MUL-2904 regression,
broaden the stdin-emphasis test across providers, and pin the
provider-agnostic guardrail.

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

* fix(daemon): keep Windows assignment brief file-only (address review)

Review catch on #3654: the previous commit added platform-agnostic prose
recommending "--content-file or --content-stdin" in the Available Commands
entry and the assignment-triggered step-6 example. The assignment path has
no BuildCommentReplyInstructions OS override, so on Windows an agent following
step 6 literally would pipe its final comment through PowerShell and drop
non-ASCII bytes (#2198 / #2236 / #2376) — contradicting this PR's own
Windows file-only rule in the ## Comment Formatting section.

Make the platform-agnostic surfaces defer to the OS-aware ## Comment
Formatting section (the single source of truth) instead of naming stdin.
The flag synopsis still lists all three modes.

Add TestInjectRuntimeConfigWindowsAssignmentBriefStaysFileOnly: a Windows
assignment-triggered brief must not contain any prescriptive "... or
--content-stdin" recommendation.

a6247ad714 helm: gate uploads PVC behind backend.uploads.persistence.enabled (#3655)
Adds a value (default true for backward compatibility) that gates the
uploads PersistentVolumeClaim, the backend container's volumeMount, and
the pod-spec volume. Operators who serve uploads from S3 (S3_BUCKET set)
can now set backend.uploads.persistence.enabled=false to drop the PVC
entirely, removing the ReadWriteOnce Multi-Attach barrier on the storage
side for replicas > 1.

Also makes the PVC accessModes configurable (default [ReadWriteOnce]) so
operators with a ReadWriteMany-capable StorageClass can share the
uploads volume across replicas without object storage.

Documentation: values.yaml comments and the SELF_HOSTING.md resource
list are updated to describe the new toggle.

580ad5b492 fix(issues): validate and clamp limit/offset in ListIssues (MUL-2847) (#3585)
* fix(issues): validate and clamp limit/offset in ListIssues (MUL-2847)

ListIssues parsed the limit and offset query params but never validated
them, so:
  - GET /api/issues?limit=-1  -> HTTP 500 (Postgres rejects negative
    LIMIT with SQLSTATE 2201W)
  - GET /api/issues?limit=100000000 -> unbounded read in a single
    response
  - GET /api/issues?offset=-1 -> same 500

SearchIssues and ListGroupedIssues already apply v > 0 + an upper clamp
on limit and v >= 0 on offset. This brings ListIssues to the same
pattern: ignore non-positive limit (keep default 100), clamp to 100,
ignore negative offset (keep default 0). default == clamp == 100 keeps
existing callers' behavior identical and matches the upstream issue
suggestion.

TestListIssues_LimitValidation seeds 3 issues in a dedicated project
and pins the nine boundary cases (negative/zero/huge/non-numeric
limit, negative/non-numeric offset, the clamp boundary, and explicit
small/positive-offset sanity) plus two sanity checks that an explicit
small limit and a positive offset are honored.

Fixes MUL-2847 / upstream multica-ai/multica#3563.

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

* test(issues): strengthen LimitClamp test and fix comments (MUL-2847)

Address review feedback from @Lambda and @Emacs on PR #3585:

1. The 3-row set in TestListIssues_LimitValidation can't distinguish
   'clamp fired' from 'clamp missing': with only 3 rows, limit=100000000
   returns 3 rows whether or not the clamp exists. Split the clamp
   behavior into a new TestListIssues_LimitClamp that seeds 101 issues
   and asserts len(issues) == 100 for limit=100/101/200/100000000, plus
   limit=50 honored below the clamp. Without the clamp line, the
   huge/above-clamp subtests would fail with len == 101.

2. Fix the misleading comment that claimed 'limit=0 -> same 500'.
   Postgres LIMIT 0 is valid SQL and returns zero rows. The guard
   exists for sibling-consistency (SearchIssues / ListGroupedIssues
   already treat v <= 0 as 'use default'), not to avoid a 500. Move
   the limit=0 case out of TestListIssues_LimitValidation since it's
   not 500-related; TestListIssues_LimitClamp's 'no limit returns
   default page of 100' subtest pins the default behavior anyway.

3. Add a subtest that pins the offset+clamp composition
   (limit=200&offset=50 against 101 rows = 51 rows), proving the
   clamp caps the page size while offset still indexes the full
   result set.

4. Fix gofmt: the original file's leading-bullet comment indentation
   was off by two spaces; gofmt -l now reports clean.

All 14 subtests across both functions pass; full ./internal/handler/
suite still passes (3.2s).

f539fdba83 feat(onboarding): backfill prompt for missing source attribution (MUL-2796) (#3550)
* feat(onboarding): backfill prompt for users missing source attribution

Adds a one-shot popup shown after login to already-onboarded users
whose `onboarding_questionnaire.source` was never recorded — either
they completed onboarding before the source step shipped, or they
clicked Skip on it. Reuses the existing 12-option StepSource UI and
the existing `PATCH /api/me/onboarding` endpoint, so no schema or
backend changes.

Web renders it as a route at /onboarding/source (sibling of the
reserved /onboarding); desktop dispatches it as a WindowOverlay per
the Route categories rule. Submit and explicit Skip are terminal;
the close X bumps a per-user localStorage counter and stops appearing
after 3 dismissals.

Emits source_backfill_shown / submitted / skipped / dismissed PostHog
events so the funnel can be tracked separately from first-time
onboarding.

For MUL-2796.

* fix(onboarding): preserve role/use_case and respect dismiss cap in source backfill

Round-2 fixes from Emacs's review of #3550:

1. PATCH wipe: `PATCH /api/me/onboarding` replaces the JSONB column
   wholesale (server/internal/handler/onboarding.go), so sending only
   the source slots was wiping role/use_case/version for exactly the
   historical users this targets. Read user.onboarding_questionnaire,
   overlay the source fields client-side via mergedQuestionnairePatch,
   and send the full shape. 7 unit cases cover the merge semantics.

2. Legacy single-string source: pre-multi-select rows wrote
   `source: "search"` as a bare string. needsSourceBackfill now treats
   that as already answered, matching mergeQuestionnaire (views) and
   stringOrSlice.UnmarshalJSON (server). Flipped the existing test and
   added empty-string + null coverage.

3. Dismiss cap honored in callback: the web auth callback was passing
   dismissCount=0, which would force-route capped users through
   /onboarding/source on every login (the route page would bounce them
   onward, but only after a blank detour and a re-fired
   `source_backfill_shown` event). Added readSourceBackfillDismissCount
   so the callback reads the same per-user localStorage bucket the
   prompt writes to. Test asserts a count of 3 bypasses the detour.

* test(onboarding): clear source-backfill dismiss counter in callback test beforeEach

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

* fix(onboarding): footer hint text matches the Submit button on the backfill prompt

The Source step's hint reads "Hit Continue when you're ready" because
its commit button is "Continue". The backfill view ships a "Submit"
button instead, so the inherited hint was misleading. Add a dedicated
`source_backfill.hint_ready` key across en / zh / ko and use it here.

Caught during browser E2E in the round-2 verification stack.

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

* fix(onboarding): magic-code login also detours through source backfill

The round-2 fix in PR #3550 only wired the source-backfill detour
into the OAuth `/auth/callback` post-success path. Magic-code login
goes through `/login` → `handleSuccess()` which calls
`resolveLoggedInDestination()` and pushes directly to the workspace,
so those users never reach `/onboarding/source`. Caught during the
local-env demo for Jiayuan.

Add `maybeSourceBackfillDetour` to the login page and apply it in
both the already-authenticated useEffect and the post-verify-code
handler. Predicate consults the same per-user localStorage bucket
the prompt writes to, so a user who hit the close-X cap on this
browser flows straight through.

* refactor(onboarding): source backfill is a workspace-mounted modal, not a route detour

Per UAT, the prompt should overlay the workspace as a Dialog with the
workspace visible behind a dimmed backdrop — the original brief and
reference screenshot both showed a modal. PR #3550 shipped a full-window
takeover (web /onboarding/source + desktop WindowOverlay) which Jiayuan
rejected.

This commit replaces the full-window view with a Dialog-based
`<SourceBackfillModal />` mounted once inside the shared `DashboardLayout`
(packages/views/layout). The modal self-mounts: it reads
`needsSourceBackfill(user, dismissCount)` and opens itself when the
predicate flips to true; X / ESC / outside-click all bump the per-user
localStorage cap and close.

Removed:
- apps/web/app/(auth)/onboarding/source/page.tsx (route)
- paths.sourceBackfill (no longer needed)
- callback page detour
- login page maybeSourceBackfillDetour
- desktop WindowOverlay type "source-backfill"
- desktop navigation interception of /onboarding/source
- desktop App.tsx dispatch effect
- pageview-tracker case
- views/onboarding `SourceBackfillView` + `readSourceBackfillDismissCount` exports

Preserved (semantics unchanged):
- `needsSourceBackfill` predicate (incl. legacy single-string source coercion)
- `mergedQuestionnairePatch` so role / use_case survive Submit / Skip
- PostHog events: source_backfill_shown / submitted / skipped / dismissed
- Per-user dismiss-count cap (3) in localStorage
- en / zh / ko i18n strings

Tests:
- 7 new tests for the modal in packages/views/onboarding/source-backfill-modal.test.tsx
- Adjusted apps/web/app/auth/callback/page.test.tsx: detour tests dropped,
  one assertion remains that onboarded users with missing source land in
  the workspace (the modal handles the rest)
- Full suite: 965 tests pass, typecheck + lint clean

* fix(onboarding): mount source-backfill modal on the desktop workspace too

Desktop's WorkspaceRouteLayout never wraps DashboardLayout, so the
previous commit's modal mount only fired for web. Regression: desktop
users were not seeing the prompt at all.

Wire the same `<SourceBackfillModal />` next to `<WelcomeAfterOnboarding />`
inside `workspace-route-layout.tsx`, with the matching
`!overlayActive` suppression so the Dialog doesn't portal-jump above
an active pre-workspace WindowOverlay (onboarding / accept-invite /
new-workspace). Same component on both platforms — single source of
truth lives in packages/views/onboarding/source-backfill-modal.tsx.

Also drop the now-stale `source-backfill detour` comment in the web
callback test fixture (Emacs nit, non-blocking).

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

* test(desktop): assert workspace-route-layout mounts source-backfill modal

Two structural tests pinning the round-4 fix:

- `mounts SourceBackfillModal when no WindowOverlay is active` —
  guards against the regression Emacs caught (modal silently absent
  on desktop because the previous round only wired DashboardLayout).
- `suppresses SourceBackfillModal while a WindowOverlay is active` —
  mirrors the existing `!overlayActive` rule that WelcomeAfterOnboarding
  already relies on so a portal-rendered Dialog can't visually outrank
  an active pre-workspace overlay.

Mocks the SourceBackfillModal with a marker component so the test
asserts mount/unmount without depending on the modal's own predicate
gate.

* fix(onboarding): backfill modal Other toggles off; entrance settles after 700ms

UAT round-3 follow-ups from Jiayuan:

1. **Other can't be deselected**: the modal kept a parallel
   `pendingOther` flag set to true on every Other click, and
   `IconOtherOptionCard`'s row click was guarded with
   `if (!selected) onSelect()` — so a second click neither flipped
   pendingOther nor reached the parent toggle. Drop `pendingOther`
   (the `source.includes("other")` derivation is already authoritative)
   AND add an opt-in `allowToggleOff` prop to `IconOtherOptionCard`
   that lets the row toggle when already selected. The text input
   stops click propagation so typing never deselects.

2. **Rebase + absorb GitHub channel**: rebased onto origin/main which
   added `social_github` (PR #3612). Modal's option list now mirrors
   StepSource — GitHub slotted between YouTube and Other social,
   reusing the existing `GitHubIcon`.

3. **Soft entrance**: defer the dialog open by 700ms after the user
   lands on a workspace so the underlying view paints first and the
   modal feels like an inviting prompt rather than a hard block.
   Honour `prefers-reduced-motion: reduce` (open immediately for
   users who have opted out of incidental motion).

Tests:
- New `Other toggles off on the second click instead of getting stuck`
- New `renders the GitHub channel rebased from origin/main`
- New `defers the entrance by ~700ms when the user has not opted into
  reduced motion`
- Existing tests stamp `prefers-reduced-motion: reduce` in beforeEach
  so the dialog opens synchronously and they don't need to drive
  fake timers.

Full suite passes (969 tests).

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

* fix(onboarding): backfill modal opens reliably + Other deselects via icon area

Three follow-up fixes after live UAT:

1. Strict-mode regression on entrance delay: the gate ref was being
   stamped when the effect *scheduled* the timer, so React Strict
   Mode's double-invoke cleared the first timer and then bailed on
   the second pass because the ref was already set, leaving the
   dialog forever closed. Stamp the ref only inside the timer
   callback (or synchronously when reduced-motion is on) so the
   second strict pass starts a fresh timer.

2. Other deselect: dropping `pendingOther` wasn't enough — the input
   that replaces the label when Other is selected was previously
   stopping click propagation, so a re-click on the row never
   reached the toggle. Remove `e.stopPropagation()` and instead let
   the row's onClick ignore clicks whose target IS the input
   (typing / focusing the input still doesn't deselect; clicks on
   the icon, padding, or border do).

3. Tests: drive the Other re-click via Playwright `click({position:
   {x:24,y:24}})` so the click lands on the icon area instead of the
   center of the input, matching real-user behaviour.

* refactor(onboarding): source picker is single-select primary source

Per Jiayuan's call after the survey of HDYHAU UX in PLG SaaS (Linear /
Vercel / Loom / Notion / Webflow / Stripe / Figma / Cursor / PostHog
mostly skip the question entirely; where it's asked the documented
default — Fairing / Recast / HockeyStack / Ruler Analytics — is to
capture the primary source so channel weights sum to 100% and ROI
math is defensible).

Modal + StepSource both pivot from multi-select to single-select
radio. Server schema is intentionally untouched: `source` stays
`string[]` for back-compat with v2 multi-select rows; the client
always sends a one-element array. Zero migration, zero data loss.

Frontend:
- `source-backfill-modal.tsx`: state pivots from a multi-element
  `source: Source[]` to a single `pickedSlug` derived from
  `source[0]`; click handler replaces the array instead of toggling.
  Cards switch to `mode="radio"`, the fieldset gets `role="radiogroup"`,
  the now-redundant `pendingOther` and `allowToggleOff` opt-in go
  away — radio mode means no toggle-off, so the original UAT bug
  ("Other can't be deselected") is structurally impossible.
- `step-source.tsx`: drop the `multiSelect` prop so it routes
  through `step-question.tsx`'s existing radio path (same one
  StepRole already uses). Picking a second option replaces the
  first; switching away from Other clears `source_other` so a stale
  value can't leak.
- `icon-option-card.tsx`: revert the `allowToggleOff` plumbing.

Tests:
- `source-backfill-modal.test.tsx`: drop the multi-select toggle-off
  assertion; add "picking a second option replaces the first" with
  explicit radio-role queries.
- `step-source.test.tsx`: rewrite multi-select tests as single-select
  (no more "stacks several picks" / "toggle off" cases); add
  "switching away from Other clears source_other".

Full suite (970 tests) green, typecheck + lint clean.

* docs(onboarding): refresh stale multi-select comments around source

Comment-only follow-up to the single-select refactor in d14f9d09f.
Five docblocks still described `source` as multi-select; they now
correctly say single-select and explain the array shape is kept
purely for v2 back-compat with the JSONB column.

- packages/core/onboarding/types.ts — QuestionnaireAnswers docblock
- packages/core/onboarding/store.ts — PostHog mirror comment
- packages/views/onboarding/steps/step-question.tsx — header docblock,
  canContinue branch, and footer-hint comment (Source moves from the
  multi-select side to the single-select side; Use case stays as the
  remaining multi-select consumer)
- server/internal/handler/onboarding.go — questionnaireAnswers docblock
  and the stringOrSlice fall-back comment (the column "going multi-
  select" is no longer the current state; rename to "pre-array shape")
- server/internal/analytics/events.go — OnboardingQuestionnaireSubmitted
  docblock

No behaviour changes. Tests + Go build still green.

* i18n(onboarding): add ja translations for source-backfill keys

The Japanese locale landed on main (PR #3538) after this branch
started, so my source-backfill round-2 keys (`common.close`,
`source_backfill.eyebrow / lede / submit / hint_ready`) never made
it into ja and the parity test fails in CI. Add them now with
translations that match the en/zh-Hans/ko wording and tone.

91c1e51411 feat(editor): add / slash-command palette for invoking agent skills (#3159)
* feat(editor): add / slash-command palette for invoking agent skills

Adds a `/` trigger in the chat box that opens a popover listing the active
agent's skills. Selecting an item inserts a `[/label](slash://skill/<id>)`
token; the daemon extracts those IDs in `buildChatPrompt` and emits an
"Explicitly selected skills:" block using the canonical names from the
agent's skill registry — labels are display-only and never trusted.

Built on Tiptap's `Mention` extension so the suggestion lifecycle,
keyboard routing, and IME handling mirror the existing `@` mention UX.
Item list is sourced from the React Query workspace cache (no per-keystroke
fetch). Gated behind a new `enableSlashCommands` prop so only `chat-input`
opts in; other `ContentEditor` consumers (issue editor, comments) are
unaffected. Read-only markdown surfaces render the token as a `.slash-command`
pill via a custom link renderer + sanitize-schema/url-transform allowlists.

Closes #3108

* fix(i18n): add slash_command editor copy for ko/ja

The PR added slash_command popover empty-state keys to en + zh-Hans only;
locales/parity.test.ts requires every locale to cover every EN key, so ko
and ja failed CI. Add the two keys (no_skills_configured, no_results)
matching existing skill terminology (스킬 / スキル).

2348301d2b fix: gate private squad leader bypass (MUL-2860) (#3648)
* fix: gate private squad leader from being triggered by unauthorized members

Add canEnqueueSquadLeader helper that checks canAccessPrivateAgent before
allowing a squad leader to be enqueued. Gate all EnqueueTaskForSquadLeader
call sites:

1. enqueueSquadLeaderTask (comment trigger, assign trigger, backlog→todo)
2. triggerChildDoneSquad (child-done → parent squad leader)
3. autopilot.go (defensive comment; actor is always agent → always passes)

Also fix validateAssigneePair's squad branch to run canAccessPrivateAgent
on the squad leader, returning 403 'cannot assign to squad with private
leader' when the actor lacks access.

Thread actorType/actorID through notifyParentOfChildDone →
dispatchParentAssigneeTrigger → triggerChildDoneSquad so the child-done
path can enforce the private-leader gate.

Regression tests:
- Plain member blocked from create-issue to private-leader squad (403)
- Plain member blocked from update-issue to private-leader squad (403)
- Owner allowed to assign private-leader squad
- Plain member comment on squad-assigned issue doesn't trigger private leader
- Child-done by plain member doesn't trigger parent's private leader
- Agent actor can still trigger private leader via comment

Closes MUL-2860

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

* fix: add private-leader gate to autopilot save + dispatch paths

- validateAutopilotAssignee squad branch: call canAccessPrivateAgent on
  the leader, returning 403 for unauthorized members at save time.
- service/autopilot.go: add canCreatorAccessPrivateLeader helper that
  mirrors the handler-level canAccessPrivateAgent logic (agent creators
  pass; member creators must be owner/admin or agent owner).
- Gate both dispatch paths (dispatchCreateIssue and dispatchRunOnly)
  with fail-closed check: if leader is private and creator lacks access,
  the run is skipped instead of triggering the private leader.

Regression tests:
- Plain member create autopilot to private-leader squad → 403
- Plain member update autopilot to private-leader squad → 403
- Owner create autopilot to private-leader squad → 201
- Owner-created autopilot dispatch → issue_created (positive)
- Legacy plain-member-created autopilot dispatch → skipped (fail-closed)

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

* test: add run_only legacy private-leader squad dispatch regression test

Covers the dispatchRunOnly path explicitly, complementing the existing
create_issue dispatch test. Both dispatch branches now have direct test
coverage for the private-leader fail-closed gate.

Retired agents (agent.archived_at set) previously read as offline across
the agent dot, hover card, detail badge, and squad member list — a
leftover online runtime row could even make them look reachable. Add a

signal so a retired agent never reads as live or merely offline.

b72434da68 refactor(chat,issues): unify hover-swap row pattern + drop archived chat sessions (#3634)
* refactor(chat): rework chat history list

- Drop legacy archived sessions from the history dropdown. The
  soft-archive feature was removed, so status='archived' rows are dead
  data; exclude them instead of showing a collapsed "archived" group.
  Rename the section heading "Active" -> "Chat history".
- Swap hover row actions into the status column's slot instead of an
  absolute overlay: status is hidden on hover and actions take its
  place inline, while the title keeps flex-1. No mid-row gap, no
  overlap, no text bleed-through.
- Remove orphaned i18n keys (active_group, archived_group,
  archived_label) across en/zh-Hans/ko.

* refactor(issues): align execution log rows with the chat hover-swap pattern

- Drop the fixed w-20 status column that forced premature truncation of
  the trigger text and left a mid-row gap; status now sizes to content.
- Running tasks render only the spinner (sr-only label retained for a11y
  and tooltip); the redundant "Working" text is removed.
- Hover swaps status for actions in place (RowStatus hidden, RowActions
  inline) instead of an absolute gradient overlay. Applies to both
  active and past ("show past runs") rows via the shared RowShell /
  RowStatus / RowActions.

Known tradeoff: dropping the absolute+opacity slot also drops the
group-focus-within keyboard reveal, so cancel/retry are no longer
Tab-reachable. Matches the chat pattern; revisit if keyboard access for
row actions becomes a requirement.

1e1a4f7845 fix(daemon): fix Copilot CLI invocation on Windows and strip shell quotes from custom args (MUL-2876)
Bug 1: detect copilot.cmd/.bat on Windows and invoke the sibling .ps1 directly via powershell -File, bypassing cmd.exe %* re-tokenisation that mangled the multi-line -p prompt. Shared rewriteCmdToPS1() now serves cursor, pi, and copilot.

Bug 2: filterCustomArgs (shared by all agent backends) strips one outer layer of shell quotes via unshellQuoteArg() before processing, so shell-style custom args like --deny-tool='write' no longer reach the CLI with literal quotes.

700cd97407 feat(workspace): add per-workspace logo upload (#2760)
Adds avatar_url column to workspace, threads it through the API +
WorkspaceAvatar component, and adds a click-to-upload editor in the
workspace settings tab. Mirrors the squad avatar pattern (migration 086);
UI strings use "logo" while the schema/code uses avatar_url for codebase
consistency with user.avatar_url and squad.avatar_url.

- migration 093: ALTER TABLE workspace ADD COLUMN avatar_url TEXT
- UpdateWorkspace SQL + handler accept avatar_url (auth gated to
  owner/admin at the router via RequireWorkspaceRoleFromURL)
- WorkspaceAvatar renders <img> when avatar_url is set, falls back to
  the initial-letter span otherwise
- workspace-tab.tsx adds a 16x16 click-to-upload logo editor at the
  top of the general settings card, using useFileUpload + accept=
  image/png,image/jpeg,image/webp (server stores under workspaces/{id}/)
- en + zh-Hans settings i18n strings added

674be86add fix(tasks): cancel autopilot run_only & quick_create tasks (MUL-2827) (#3615)
CancelTaskByUser (POST /api/tasks/{taskId}/cancel) keyed cancellation off
issue_id / chat_session_id alone, so any task whose only source link was
autopilot_run_id (run_only autopilots) or quick_create context fell into the
dead else branch and 404'd with "task not found" — even though the task was
visible (and showed a cancel X) on the agent Activity tab.

Enforce tenancy uniformly through the task's owning agent instead: agent_id is
NOT NULL on every task row (ON DELETE CASCADE), and agents are workspace-scoped,
so GetAgentTaskInWorkspace (task JOIN agent ON workspace) is a single tenant
guard that works regardless of which optional source FK is set — including
orphan tasks whose autopilot_run_id was SET NULL after the autopilot was
deleted. Privacy layers on top: chat tasks stay creator-only, and every other
task mirrors the agent Activity / snapshot private-agent visibility gate via
canAccessPrivateAgent so the id-only endpoint is never more permissive than the
surface that exposes the task.

Tests cover run_only (same-ws success, cross-ws 404 no-mutation), quick_create,
retry clones, issue-task regression, chat non-creator 403, and private-agent
plain-member 403.

0f9d9d1494 fix(skills): align Go/TS frontmatter coercion for non-scalar values (#3614)
The Go SKILL.md frontmatter parser unmarshalled into a {Name,Description}
string struct, so a non-scalar value (a list/map written where a scalar
belongs) made the whole decode fail and dropped even a valid sibling
`name`. The TS parser instead kept the name and JSON-encoded the value,
so the file-viewer (TS) and the import path (Go) could disagree about
the same SKILL.md.

Decode into a generic map and coerce per key on the Go side, mirroring
the TS coercion (scalars -> literal form, sequences/mappings -> JSON), so
both sides produce identical results and a structured value never
discards a sibling key. Rename ParseFrontmatter -> ParseSkillFrontmatter
to remove the cross-language name clash with the TS parseFrontmatter
(which returns {frontmatter, body}), and drop the unused TS
parseSkillFrontmatter export.

Add parity tests for sequence/mapping values plus name-only,
description-only, leading-blank-line and triple-dash-in-body edge cases
on both sides.

Follow-up to #3543 / MUL-2842.
