270d177475 fix: broken "Add a computer" command on Multica Cloud + two CLI amplifiers (MUL-3087) (#3817)
* fix(server): recognize official cloud by frontend host in daemon setup config

The 'Add a computer' dialog builds its command from /api/config's
daemon_server_url/daemon_app_url, falling back to 'multica setup' when
both are empty. The official cloud is meant to omit them, but the
omission only fired when MULTICA_PUBLIC_URL=https://api.multica.ai. When
that env is unset the server URL defaults to the frontend origin and the
old guard (which required serverURL host == api.multica.ai) didn't match,
so the dialog emitted 'multica setup self-host --server-url
https://multica.ai' — pointing the daemon backend at the frontend (no
/health, no WebSocket proxy).

Identify the official cloud by its frontend host alone (multica.ai /
app.multica.ai) so a missing or misconfigured MULTICA_PUBLIC_URL can no
longer leak the broken self-host command. Regression from #3474.

* fix(cli): probe before persisting self-host config to preserve auth on failure

setup self-host wrote a fresh CLIConfig{ServerURL, AppURL} (a full
overwrite that drops the saved token) and only then probed the server,
returning early on failure. A failed probe therefore logged the user out
and left them unconnected, with no recovery in the same command.

Probe first via persistSelfHostConfigIfReachable: an unreachable server
leaves the existing config — and its token — untouched (failed setup =
no-op). The prober is injected so both branches are unit-tested.

* fix(daemon): serve health before preflight so daemon start readiness is accurate

The CLI's 'daemon start' polls the health endpoint for 15s expecting
status=running, but the daemon only began serving health after
preflightAuth, whose initial workspace sync detects every configured
agent's version by exec'ing it (~20s cold with 8 agents). Health served
too late, so a perfectly healthy daemon printed 'may not have started
successfully'.

Start the health server right after resolveAuth (which still fails fast
on a missing token) and before the slow preflight, so readiness reflects
the daemon core being up rather than agent-version detection finishing.

* fix(daemon): gate /health readiness so daemon start can't report a false start

Serving health before preflightAuth fixed the false-negative (a healthy
daemon printed "may not have started"), but health still returned
status:"running" unconditionally — before preflight (PAT renew + workspace
sync + runtime registration) had completed. `daemon start` and the desktop
treat "running" as ready, so a slow or *failing* preflight could be
misreported as a started daemon: setup prints "connected", then the process
exits or hangs in agent-version detection with no runtime registered. That
is harder to diagnose than the original false-negative.

Split liveness from readiness: bind/serve the health port early (so callers
see a live "starting" daemon instead of connection-refused), but report
status:"starting" until d.ready is set after preflight, then "running".

- daemon.go: add d.ready (atomic.Bool); set it true after the background
  loops launch, before pollLoop.
- health.go: healthHandler reports "starting" until ready, else "running".
- cmd_daemon.go: `daemon start` waits for "running" with a deadline raised
  to 45s (covers cold-start agent detection) and a clearer "still starting"
  message; new daemonAlive() helper treats both "running" and "starting" as
  a live daemon, so the already-running guard, restart, and stop act on a
  starting daemon and don't double-spawn or race its listener; `daemon
  status` shows "starting" distinctly.

Older CLIs/desktop that only know "running" safely treat "starting" as
not-ready (status != "running"), so no boundary break.

Tests: health reports starting-then-running; daemonAlive truth table.

* fix(desktop): handle daemon "starting" health status in lifecycle

The daemon now reports /health status:"starting" until preflight completes
(liveness/readiness split). That made "starting" a new external contract of
/health, but the Desktop daemon-manager only knew "running", so the readiness
fix would have moved the CLI's false-negative into a Desktop start regression:

- `daemon start` now blocks up to 45s waiting for readiness, but the Desktop
  spawned it via execFile({ timeout: 20_000 }). On a cold start (the ~20s agent
  detection this PR targets) Electron killed the CLI supervisor at 20s and
  reported a start failure, even though the detached daemon child kept booting —
  the UI flashed "stopped" then "running". Raise the timeout to 60s (must exceed
  the CLI's 45s startupTimeout).
- The Desktop treated only raw status === "running" as a live daemon, so a
  daemon that was still "starting" (booting on its own or started via the CLI)
  showed as "stopped", and startDaemon() would spawn a second one — which the new
  CLI rejects as "already running", surfacing as a start error.

Add daemonStatusAlive() (shared, pure, unit-tested) mirroring the Go daemonAlive()
and use it for liveness: fetchHealth() surfaces a daemon-reported "starting" as
state "starting" regardless of our own currentState; startDaemon()'s
already-running guard and the restart-on-user-switch guard treat "starting" as an
existing daemon. version-decision stays gated on "running" (readiness, not
liveness) — unchanged.

Verified: desktop typecheck, eslint, full vitest suite (193 tests) all pass.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

3708fb0f07 fix(daemon): inactivity-based agent run timeout, no wall-clock guillotine (MUL-3064)
Active long-running sessions are no longer killed by a fixed wall-clock deadline. Liveness is delegated to the idle watchdog (MULTICA_AGENT_IDLE_WATCHDOG, default 30m) with a larger in-flight-tool budget (MULTICA_AGENT_TOOL_WATCHDOG, default 2h). MULTICA_AGENT_TIMEOUT is an opt-in absolute cap (default 0 = no cap). The server-side 2.5h sweeper is unchanged as a coarse backstop.

Fixes #3745.

62925b97f1 chore(cli): remove the --from-template flag from agent create (#3805)
* chore(cli): remove the --from-template flag from agent create

The `--from-template` CLI flag was an untaught, immature surface (the
built-in skill's source-map explicitly marked the template path "out of
scope"). It also silently ignored sibling create flags (--custom-env,
--mcp-config, etc.) by short-circuiting before body assembly. Remove the
flag and its runAgentCreateFromTemplate handler from the CLI.

Scope is CLI-only. The agent-template product feature stays intact:
- registry server/internal/agenttmpl/ (embedded curated templates)
- handler server/internal/handler/agent_template.go
- routes GET /api/agent-templates, GET /api/agent-templates/{slug},
  POST /api/agents/from-template
- the onboarding "create from template" flow (packages/views/onboarding)

The onboarding flow calls the API directly and does not depend on the
CLI flag, so removing the flag does not affect it.

Updates the multica-creating-agents source map accordingly.

MUL-3070

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

* fix: correct source-map note on agent-template usage + guard --from-template

Review of #3805 (MUL-3070) flagged a factual error in the source-map note:
it claimed onboarding uses the agent-template backend. It does not.
`packages/views/onboarding/steps/step-agent.tsx` builds four hardcoded
local presets (i18n-resolved) and creates via plain `POST /api/agents`
(`createAgent`), never `POST /api/agents/from-template`. The whole
agent-template stack (registry, handler, routes, `packages/core` client +
query wrappers) is orphaned — the removed CLI flag was its only non-test
caller. Rewrite the note to say so.

Also add a regression test asserting `agent create` exposes no
`--from-template` flag, so it can't be silently re-added.

18a5224fe8 feat(cli): add --mcp-config flags to agent create/update (#3799)
Agents already support an mcp_config field (consumed by the daemon →
provider at task time) and the agent-settings UI exposes an MCP tab, but
the CLI had no way to set it. This adds the missing CLI surface, mirroring
the existing custom-env pattern:

- `agent create` and `agent update` gain --mcp-config / --mcp-config-stdin
  / --mcp-config-file. The stdin/file channels keep MCP server tokens out
  of shell history and 'ps'; the three channels are mutually exclusive.
- The value is validated as a JSON object (or the literal `null` to clear,
  on update), matching the agent-settings MCP tab. Empty stdin/file input
  errors instead of silently clearing a secret-bearing field.
- Unlike custom_env, mcp_config IS settable via `agent update` — it is
  persisted through the generic UpdateAgent endpoint (no dedicated audited
  endpoint), so both create and update expose the flags.

Adds parser/resolver unit tests (incl. secret-leak sanitization) and
updates the multica-creating-agents built-in skill + source map.

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

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

5e1a6c4853 fix(cli): degrade 'issue metadata list' to {} on /metadata 404 (#3757)
Self-hosted backends without the per-issue metadata route (older builds,
unapplied 105_issue_metadata migration, or proxy/ingress misroutes) reply
404 to GET /api/issues/:id/metadata. The agent runtime bootstrap calls
'multica issue metadata list <issue> --output json' best-effort, but a
non-zero exit was being escalated by Hermes into a failed agent run even
when the rest of the work succeeded.

This makes only the 'list' verb best-effort: a 404 from /metadata now
prints {} (or an empty table) and exits 0. Other status codes (401, 500,
etc.) keep real error semantics, and 'metadata get / set / delete' are
unaffected — those represent explicit caller intent.

To support the status-code check without changing the user-facing error
string, GetJSON now returns *cli.HTTPError on HTTP failures (the format
'GET <path> returned <code>: <body>' is preserved by HTTPError.Error()).

ae27058b0a fix(attachments): unified download endpoint with mode + presign + proxy (MUL-2976) (#3747)
Fix attachment download for self-hosted deployments using private S3-compatible buckets without CloudFront. Closes #3721.

**Server**

- New unified `GET /api/attachments/{id}/download` endpoint that picks CloudFront / S3 presign / server proxy at request time.
- `ATTACHMENT_DOWNLOAD_MODE=auto|cloudfront|presign|proxy` and `ATTACHMENT_DOWNLOAD_URL_TTL` env knobs; `auto` routes Docker hostnames / localhost / private IPs through the proxy and public S3 endpoints through presign.
- `Storage.PresignGet` capability; S3 implementation generates presigned GET URLs.
- `attachmentToResponse` returns the unified relative endpoint instead of leaking raw unsigned S3 URLs when CloudFront is not configured. Proxy path streams via `io.Copy` with `Content-Disposition` / `Content-Length` / `Cache-Control: no-store` / `X-Content-Type-Options: nosniff`.

**Clients**

- CLI / Desktop / Mobile resolve relative `download_url` values against the configured API base. Desktop covers the Electron native download bridge and the media preview modal; Mobile covers `Linking.openURL`, the markdown image RN loader, and the composer's completed non-image file chip.
- Mobile gains a minimal Node-environment vitest lane wired into `mobile-verify.yml`.

**Docs**

- `.env.example`, `docker-compose.selfhost.yml`, `SELF_HOSTING_ADVANCED.md`, and the `environment-variables` doc set updated with the new env keys and the `ATTACHMENT_DOWNLOAD_MODE=proxy` recommendation for Docker / VPC-internal object stores.

**Tests**

- `internal/storage`, `internal/cli`, `internal/handler` (download endpoint, mode selection, proxy header, `/content` non-regression), `cmd/server` (trusted proxy parser).
- `packages/views/editor/use-download-attachment.test.tsx` and `attachment-preview-modal.test.tsx` exercise relative URL resolution + absolute pass-through.
- `apps/mobile/lib/attachment-url.test.ts` covers every helper branch plus the composer non-image chip case.

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

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

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

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

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

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

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

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

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.

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.

- 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`).

* 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.

* 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.

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

* 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.

* 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).

MUL-2671

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

CI frontend job tripped on the ja locale parity check: ja is missing

The ko fix earlier covered Korean; ja was added separately on main
and the merge surfaced these gaps. Translations mirror the en source

* 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).

  - 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).

* 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.

* 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.

de900b2ba6 feat(server): funnel/community/commercial business metrics + PostHog pairing (MUL-2949) (#3698)
* feat(server): funnel/community/commercial business metrics + PostHog pairing (MUL-2949)

PR3 of the Grafana board metrics split (parent MUL-2328).

Adds 23 new Prometheus counter/histogram families to the PR2 BusinessMetrics
collector covering the activation/community/commercial funnels, and binds
every PostHog event emission to a matching metric increment so the two sides
cannot drift.

Funnel: signup, workspace_created, team_invite_sent/accepted, onboarding_*,
cloud_waitlist_joined.
Content: issue_created, chat_message_sent, agent_created, squad_created,
autopilot_created, issue_executed.
Runtime: runtime_registered/ready/failed/offline + ready_seconds histogram,
daemon_ws_message_received_total.
Autopilot: autopilot_run_started/terminal/skipped.
Webhook/GitHub: webhook_delivery_total, github_event_received_total,
github_pr_review_total, github_pr_merge_seconds histogram.
CloudRuntime: cloudruntime_request_total + duration histogram, wired through
a small RequestRecorder interface so the cloudruntime package stays decoupled
from metrics.
Commercial: feedback_submitted, contact_sales_submitted.

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.

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

* 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.

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.

* fix(cli/login): accept mcn_ Cloud Node PATs alongside mul_ (MUL-2815)

multica login --token rejected anything not starting with mul_, so
users with a Multica Cloud Node PAT (mcn_ prefix) hit
"invalid token format: must start with mul_" even though the server
middleware verifies both kinds.

Replace the inline literal check with validateLoginTokenPrefix(), backed
by a small loginTokenPrefixes list ({mul_, auth.CloudPATPrefix}) so the
accepted set has one source of truth. Add unit-test coverage so adding
a new prefix in future is an obvious one-line edit.

* fix(cli/login): mention mcn_ Cloud Node PATs in --token help and comments

Follow-up to 47e423c4: the login command now accepts mcn_ tokens but the
help string and surrounding comments still only documented mul_, so a user
running 'multica login --help' couldn't tell that mcn_ was supported.
Update the --token help string and the cobra Args / NoOptDefVal comments
to list both mul_... and mcn_... prefixes.

75b5be3f8e feat(comments): roots-only thread stats + summary projection for comment list (MUL-2809) (#3505)
* feat(comments): roots-only thread stats + summary projection for comment list

Enrich the roots_only read so each root carries reply_count (recursive
descendant count) and last_activity_at (MAX created_at over the subtree),
letting an agent triage which thread to open without fetching any replies.

Add an orthogonal summary=true projection (--summary) that clips each
returned comment's content to a fixed budget and sets content_truncated,
so an agent can scan a list cheaply before pulling a full body. It composes
with every read mode (default, since, thread, recent, roots_only).

New response fields are optional (omitempty) and only populated for the
agent-facing query params, so the default response shape is unchanged for
the desktop/web and existing CLI callers.

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

* test(comments): cover roots_only + summary composition end-to-end

The summary projection composing with roots_only is the spec's headline
"table of contents" read, but it was only exercised at the CLI param-
forwarding level — no handler test asserted that a roots_only response
both clips content AND keeps reply_count / last_activity_at. A refactor
moving the clip into a per-mode branch would silently break that
composition with no failing test.

Add TestListComments_RootsOnlySummaryComposes: a long root + a reply,
read via roots_only=true&summary=true, asserting the root is clipped
(content_truncated=true) while its subtree stats still surface.

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

* refactor(comments): address review nits on roots stats + summary

- ListRootComments[Since]ForIssue: scope the recursive membership walk to a
  selected_roots CTE (the @row_limit page, with the @since cut applied up front)
  so stats are only computed over the subtrees of the roots actually returned,
  instead of every thread in the issue.
- summarizeContent: scan by rune and stop at the budget+1th rune instead of
  allocating a full []rune for the whole body, so a pathologically long comment
  costs only the budget under summary mode. Add a multi-byte (CJK) test to lock
  rune-boundary clipping.

* feat(self-host): DISABLE_WORKSPACE_CREATION env var (MUL-2777, #3433)

When self-hosters set DISABLE_WORKSPACE_CREATION=true, POST /api/workspaces
returns 403 for every caller and the UI hides every "Create workspace"
affordance (sidebar, modal, /workspaces/new page, onboarding Step 2). This
closes the gap where ALLOW_SIGNUP=false still let any signed-in user open
an isolated workspace the platform admin couldn't see.

* fix(onboarding): drive create path off workspaceCreationAllowed (#3433)

PR #3441 review: when DISABLE_WORKSPACE_CREATION=true and the user already
has a workspace, StepWorkspace still walked the resume copy (`headline_resume`
/ `lede_resume` mentioning "or start another") and `creatingActive` ignored
the flag, leaving a stale clickable create CTA possible if /api/config
arrived late.

Refactor StepWorkspace to derive a single `workspaceCreationAllowed`
boolean from the config store. It now drives:

- Initial `mode` state (defaults to "existing" when disabled + reusing so
  the CTA is pre-armed for the only valid action).
- `creatingActive` so the footer CTA cannot fall back into the create
  branch even mid-render.
- Eyebrow / headline / lede strings — adds
  `creation_disabled_{eyebrow,headline,lede}_resume` (EN + zh-Hans) for
  the disabled + reusing variant.

Tests: cover the three reachable shapes — flag off + no existing, flag on
+ no existing, flag on + existing.

4864831721 MUL-2744: feat(auth): auto-renew daemon PAT in-place within 7-day window (#3360)
* MUL-2744: feat(auth): auto-renew daemon PAT in-place within 7-day window

Daemons currently hold a 90-day PAT and have no renewal path: once the
token's expires_at passes, every request 401s and the user has to find
the silent failure in the daemon log and re-run `multica login`.

This adds an in-place renewal:

- New `POST /api/tokens/current/renew` (Auth-protected, mul_ only). The
  server checks remaining lifetime: ≥ 7 days is a no-op; < 7 days bumps
  expires_at to now + 90 days via a guarded UPDATE that makes concurrent
  renews idempotent (the WHERE expires_at < $2 clause means only one
  writer wins; the loser sees pgx.ErrNoRows and reports the already-
  extended value). No raw token rotation — the same secret stays in
  every CLI/daemon process sharing the config.

- Daemon-side `tokenRenewalLoop`: fires once on startup (covers
  machine-was-off cases) and then every 3 days. With a 7-day server
  threshold this gives at least two renewal attempts before the window
  closes, so a single network blip can't push the token out.

- 401 fallback: when the renew call comes back 401 (token already
  revoked/expired), the daemon logs a user-actionable WARN telling the
  operator to run `multica login` — instead of the current silent
  failure mode. Loop keeps running so the warning repeats until fixed.

PAT cache (auth.AuthCacheTTL = 10m) doesn't need invalidation: the next
miss after the UPDATE re-reads the row and re-caches with the bumped
TTL automatically.

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

* MUL-2744: fix(auth): renew PAT before first sync; CAS against renewal threshold

Addresses the two issues Elon raised on #3360.

Must-fix: if the PAT is already revoked/expired when the daemon starts,
syncWorkspacesFromAPI 401s and Run returns before the background
tokenRenewalLoop ever fires its initial renewal. The operator only sees
a generic auth failure in the workspace-sync log with no hint that
'multica login' is the fix. Now the startup path runs an inline
tryRenewToken first, surfacing the existing 401 WARN before anything
else gets a chance to fail. Pulled the renew + first-sync pair into
preflightAuth so the ordering invariant is enforced at one site and
tests can exercise the failure modes without spinning up the full Run
setup. Removed the redundant initial tryRenewToken from
tokenRenewalLoop — startup now owns the first call.

Nit: the previous WHERE clause on ExtendPersonalAccessTokenExpiry
(expires_at < $2) did not actually make concurrent renews idempotent
the way the comment claimed. Two callers race-computing
$2 = now + 90d produce strictly-different values, and the second
writer's $2 always exceeds the row the first writer just wrote, so the
UPDATE re-matches and bumps again. Switched to a CAS against the
renewal threshold (expires_at <= $renew_threshold_at, i.e. now + 7d):
once writer A pushes expires_at past the threshold, writer B's UPDATE
matches zero rows and the loser falls back to reporting the
already-extended value as a no-op.

Tests:
- TestPreflightAuth_RenewsBeforeWorkspaceSyncOnExpiredToken locks in
  the call ordering — renew endpoint is hit before workspaces, and the
  re-login WARN appears even though both endpoints 401.
- TestPreflightAuth_SyncProceedsWhenRenewIsNoOp covers steady-state
  startup: a renew=false no-op must still progress to workspace sync.
- TestPreflightAuth_TransientRenewFailureDoesNotBlockStartup covers a
  500 from the renew endpoint — startup must continue, no WARN.
- TestRenewPAT_ParallelRenewExtendsExactlyOnce fires N=8 concurrent
  renews at one row and asserts exactly one returns renewed=true with
  the others reporting the same already-extended expires_at, plus the
  DB carries only that single bumped value.

e3723dbb22 refactor(autopilot): centralize timezone default and cover invalid-timezone fallback (MUL-2742) (#3356)
Follow-up nits from PR #3324 review:

- Export DefaultAutopilotTriggerTimezone so the autopilot scheduler reuses
  the same source-of-truth as the service layer instead of hardcoding "UTC"
  in two places.
- Add tests that lock down the invalid-timezone fallback (e.g. "Foo/Bar")
  for both buildIssueDescription and interpolateTemplate, so a future change
  to the resolve/format helpers can't silently emit a half-formatted
  timestamp or date.

c968c13c87 feat(auth): support mcn_ Cloud Node PATs verified via Fleet (#3349)
* feat(auth): support mcn_ Cloud Node PATs verified via Fleet

Adds a new token kind, mcn_ (multica cloud node), recognized in both
the regular Auth and DaemonAuth middlewares. mcn_ tokens are minted
and owned by Multica Cloud (not the local personal_access_tokens
table); the server validates them by POSTing to the Fleet's
/api/v1/pat/verify endpoint and uses the returned owner_id as
X-User-ID for downstream handlers.

Cloud is the authoritative owner of token status, so this is a
verifier-only path with no DB fallback:

  * Fleet says valid:false -> 401 (token genuinely bad)
  * Fleet unreachable / 5xx -> 503 (transient, retry)
  * No MULTICA_CLOUD_FLEET_URL configured -> 401 (fail closed)

Verification results are cached in Redis for 60s under
mul:auth:mcn:<sha256> to bound the per-request load on Fleet without
extending the revocation window beyond what the Cloud doc allows.
Negative results are NOT cached, so a freshly minted token doesn't
get locked out by a stale 'token_not_found'.

Reuses MULTICA_CLOUD_FLEET_URL (the same env the cloud-runtime proxy
already uses) so deployments don't need a second config knob.

Tests cover the happy path, every documented invalid reason, 4xx/5xx
mapping, network error, decode error, ctx cancellation, the
fail-closed valid:true-without-owner_id case, trailing-slash URL
normalization, and the Redis cache short-circuit + negative
no-cache contract. Middleware tests pin the four 401/503/200 outcomes
in both Auth and DaemonAuth.

* auth(mcn): require owner_id to map to a real local user; drop X-User-PAT plumbing

Two related changes:

1. Cloud-verified owner_id is now checked against our local users table.
   The Cloud owner_id and our users.id share the same UUID space by
   contract; a missing local user means either the row was deleted
   under an active node or something is forging owner_ids — either
   way, fail closed.

   CloudPATVerifier.Verify takes a new OwnerLookupFunc:
     - returns (true, nil)   -> success, cache + return
     - returns (false, nil)  -> ErrCloudPATInvalid (reason='owner_unknown'),
                                NOT cached (so a freshly-created user
                                doesn't get locked out for a TTL window)
     - returns (_, error)    -> ErrCloudPATUnavailable (transient,
                                middleware emits 503)

   Both Auth and DaemonAuth wire ownerLookupFor(queries), a new shared
   helper that wraps queries.GetUser, mapping pgx.ErrNoRows / unparseable
   UUIDs to (false, nil) and other errors to a real Go error.

2. Removed all X-User-PAT plumbing. Cloud now mints node-scoped mcn_
   PATs itself during /api/v1/nodes (see multica-cloud
   docs/api/node-pat.md) and ships them into the EC2 instance via SSM,
   so multica-api no longer needs to forward the caller's mul_ PAT.
   Propagating a long-lived user PAT into a remote machine widened
   the blast radius of any node compromise; that's gone now.

   Removed:
     - cloud_runtime.go: withUserPAT option, cloudRuntimeUserPAT,
       generateCloudRuntimePAT, revokeGeneratedPAT
     - cloudruntime/Request.UserPAT field + X-User-PAT header
     - X-User-PAT from CORS allowed headers
     - obsolete handler tests:
         TestCreateCloudRuntimeNodeForwardsValidatedPAT
         TestCreateCloudRuntimeNodeRejectsUnownedPAT
         TestCreateCloudRuntimeNodeRejectsExpiredPAT
         TestCreateCloudRuntimeNodeAutoGeneratesPAT
       replaced with TestCreateCloudRuntimeNodeForwardsBody
     - X-User-PAT references in packages/core/api/client.test.ts

Tests:
  * 3 new verifier-level tests (owner_unknown not cached, lookup error
    -> Unavailable, success path is cached for both fleet AND lookup)
  * 5 new owner_lookup_test.go tests (nil queries, existing user,
    missing user, malformed UUID, DB error)
  * 1 new end-to-end DaemonAuth test (cloud says valid, no local user
    -> 401)
  * Existing X-User-PAT TS assertions removed; full vitest run passes.
  * go test ./... and go vet ./... clean on the server module.

17714c3ad1 fix(create-issue): preserve parent_issue_id through Create with agent flow (MUL-2534) (#3083)
* fix(create-issue): preserve parent_issue_id through Create with agent flow (MUL-2534)

When the create-issue modal was opened from the "Add sub issue" entry on
an existing issue and the user switched to "Create with agent", the
parent_issue_id was silently dropped: switchToAgent only forwarded
prompt + actor + project_id, the AgentCreatePanel had no notion of
parent context, and the daemon prompt never instructed the agent to
pass --parent <uuid>. The sub-issue intent was lost and the new issue
landed as a standalone.

This fix threads parent_issue_id through the whole pipeline silently —
no new editable form field, the existing carry channel handles it:

- Frontend: ManualCreatePanel.switchToAgent + AgentCreatePanel.switchToManual
  now carry parent_issue_id (and identifier, for display) so the sub-issue
  intent survives mode flips in either direction. AgentCreatePanel reads
  parent from `data`, forwards to api.quickCreateIssue, and renders a
  read-only "Sub-issue of MUL-XX" chip so the user can see the relationship.
- API: quickCreateIssue accepts optional parent_issue_id.
- Backend: QuickCreateIssueRequest validates parent_issue_id belongs to the
  same workspace (same path as CreateIssue), persists it in
  QuickCreateContext, and the daemon claim handler resolves the parent's
  identifier for prompt context.
- Daemon prompt: when ParentIssueID is set, buildQuickCreatePrompt instructs
  the agent to pass `--parent <uuid>` and treat the modal entry point as
  authoritative.

Tests cover all three hops: switchToAgent carry payload, AgentCreatePanel →
api.quickCreateIssue, and the daemon prompt's --parent injection (with both
identifier-present and UUID-only fallback branches).

* test(create-issue): cover quick-create parent trust boundary + identifier fallback (MUL-2534)

Address review on PR #3083:

- Add server-side test for POST /api/issues/quick-create parent_issue_id:
  same-workspace parent threads through QuickCreateContext.ParentIssueID,
  foreign-workspace and bogus UUIDs return 400 and never enqueue a task.
- Fall back to `data.parent_issue_identifier` in ManualCreatePanel's
  switchToAgent when the parent detail query hasn't hydrated yet, so the
  agent chip never renders "Sub-issue of " with an empty tail.

341ce7bfa5 feat: support local working directory for projects (MUL-2618 v1) (#3283)
* feat(project): add local_directory project_resource type (MUL-2662)

Adds a second project_resource type alongside github_repo so a project
can be pinned to an existing directory on a specific daemon (the v1 of
the local-working-directory flow tracked in MUL-2618). The ref schema is
{ local_path, daemon_id, label? }; local_path must be absolute and
daemon_id is required. The same (daemon_id, local_path) pair is allowed
on multiple projects by design — no UNIQUE constraint is added.

Implementation reuses the existing project_resource API surface: the new
type is wired through the validator switch with no migration, no new
events, and no daemon-handler changes (daemon already passes through
arbitrary resource types via ProjectResources). The CLI gains
--local-path / --daemon-id / --ref-label shortcuts so
`multica project resource add --type local_directory` mirrors the
existing `--type github_repo --url ...` ergonomics; the generic --ref
flag still works for both types.

Tests cover the full CRUD lifecycle, the same-path-across-projects
allowance, the same-path-same-project conflict, the validator rejections
(missing/blank/relative path, missing daemon_id, wrong payload type),
and the cross-platform isAbsoluteLocalPath helper.

* feat(project): add update endpoint + label-shadow guard for project_resource (MUL-2662)

Addresses the Elon review on PR #3263:

- Add PUT /api/projects/{id}/resources/{resourceId} with sqlc query,
  matching handler, CLI `project resource update`, and a new
  EventProjectResourceUpdated WS event. resource_type stays immutable;
  ref/label/position are all individually optional.
- Catch same-project (daemon_id, local_path) collisions where only the
  embedded label differs — the row-level UNIQUE only matches the full
  ref JSON, so a label typo would otherwise let the same working
  directory bind twice.
- Tests cover the update lifecycle (label-only / ref / clear / 404 /
  invalid path) and the label-shadow conflict on both create and
  update; the in-place rename still succeeds because the conflict
  scan ignores the row being edited.

Incidental: regenerating sqlc picked up a missing skills_local scan in
UpdateAgentCustomEnv that drifted in from #3200.

* fix(project): close bundled-create label-shadow gap + merge resource_ref on CLI update (MUL-2662)

Two follow-ups from MUL-2662 review round 2:

- CreateProject inline resources path now dedupes local_directory entries on
  (daemon_id, local_path) before opening the transaction. The DB-level
  UNIQUE(project_id, resource_type, resource_ref) constraint only fires on a
  full JSON match, so two rows with the same target but different `label`
  would otherwise slip past. Standalone POST/PUT already cover this via
  findLocalDirectoryConflict; bundled create was the missing surface.
- `multica project resource update` now seeds resource_ref from the existing
  row before applying per-type shortcut flags, so `--default-branch-hint x`
  on its own no longer constructs a payload missing `url` (which the server
  400s on). Local_directory partial edits get the same merge behavior.

* feat(desktop): local_directory project_resource UI (MUL-2665) (#3273)

* feat(desktop): local_directory project_resource UI (MUL-2665)

First UI surface for the local-working-directory flow tracked in MUL-2618.
Lets users on the desktop pin a project to an existing folder on this
machine; web stays read-only since the per-daemon check can't be done in
the browser.

What's new for the renderer:

- ProjectResourcesSection grows a desktop-only "Add local directory"
  button next to the existing GitHub-repo popover. Clicking it opens
  Electron's native folder picker, validates the path through a new
  IPC pair (existence + r/w), and submits a project_resource of
  resource_type=local_directory with daemon_id pulled live from
  daemonAPI.getStatus.
- LocalDirectoryRow renders the rename pencil + path tooltip, and
  greys out when ref.daemon_id != this machine's daemon_id (with a
  "only available on the machine that registered this directory"
  tooltip). Delete stays enabled so users can drop stale registrations
  from any device.
- LocalDirectoryHint sits above the issue-detail comment composer and
  shows "Agent will work in-place at {label} ({path})" when the issue's
  project has a local_directory matching this daemon. Hidden on web.
- TaskStatusPill picks up a new "waiting_for_directory_release" stage
  that the daemon will publish when it dequeues a task but can't
  acquire the path lock. The render is in place now so the daemon
  sibling subtask can wire the status string without an additional UI
  PR.

Plumbing:

- @multica/core/types gains LocalDirectoryResourceRef +
  UpdateProjectResourceRequest, and the api client gets the matching
  PUT method backed by the server endpoint that landed in
  2ac3faebb (MUL-2662). A useUpdateProjectResource hook drives the
  in-place label edit.
- New Electron handlers under apps/desktop/src/main/local-directory.ts:
    local-directory:pick     -> dialog.showOpenDialog (openDirectory)
    local-directory:validate -> stat + access(R_OK + W_OK)
  exposed through the preload as desktopAPI.pickDirectory /
  validateLocalDirectory. View code talks to them via a thin
  packages/views/platform helper that returns reason=unsupported on
  web instead of crashing.
- useLocalDaemonStatus exposes the local daemon's id, device name, and
  running flag from daemonAPI.onStatusChange so the renderer can do the
  cross-device match without coupling to the desktop preload typings.

Tests:

- pickStageKeys gets a unit test covering the new stage and proving
  the directory-release status outranks availability hints.
- LocalDirectoryHint tests cover the four render branches (no project,
  no daemon, foreign daemon, matching daemon).
- i18n parity stays green; new keys added under projects.resources.*
  and chat.status_pill.stages.waiting_for_directory_release in both
  locales.

Out of scope (will land separately):
- The daemon-side waiting/lock signal that flips the pill into the
  new state.
- Adding local_directory to the create-project modal's bulk
  attach flow.
- Docs page refresh for project-resources.mdx — left for the
  MUL-2618 umbrella sweep.

* fix(desktop): hide rename for foreign daemon local_directory rows (MUL-2618)

Address review nit on #3273: the rename pencil was gated only by
`canEdit`, so a foreign / unknown-daemon row still showed it even
though the spec says cross-device rows are disabled. Gate rename on
`!mismatch` so it disappears on those rows; delete stays available
so a stale registration can still be dropped from any device.

* feat(daemon): local_directory execution + path mutex + GC exception (MUL-2663) (#3274)

* feat(daemon): local_directory execution + path mutex + GC exception (MUL-2663)

Wires up the daemon side of the local_directory project_resource introduced
in MUL-2662. When a task is dispatched against a project whose resources
include a local_directory pinned to this daemon's UUID, the daemon now:

  - Validates the path (absolute, exists, daemon process can read+write,
    not in the system-root / $HOME blacklist) and fails the task fast on
    any precondition violation, with a user-readable reason.
  - Serialises concurrent tasks on the same on-disk path via a
    daemon-local LocalPathLocker keyed by symlink-resolved realpath. The
    lock is held for the entire task lifetime (claim → context write →
    agent → result report).
  - When the lock is contended, the daemon flips the row to a new
    waiting_local_directory status on the server (carrying a wait_reason
    like "<path> (held by task <short id>)") so the UI can render
    "等待本地目录释放" instead of leaving the row silently in dispatched
    past the sweeper timeout. The status accepts being woken into running
    once the lock is acquired.
  - Sets execenv.WorkDir to the user's path (no copy, no mount). envRoot
    still lives under workspacesRoot/<wsID>/ and hosts output/, logs/, and
    .gc_meta.json — the daemon's logbook for the run.
  - Stamps GCMeta.LocalDirectory=true so the GC loop never RemoveAlls
    envRoot for these tasks (gcActionClean → gcActionCleanArtifacts,
    gcActionOrphan → gcActionSkip). The user's directory was never under
    envRoot to begin with, so this is defense in depth.
  - Skips execenv.Reuse for local_directory tasks because the prior
    WorkDir is the user's path and reusing it through that code path
    loses the envRoot association the GC loop needs. Prepare is cheap
    here (no clone, no copy), so always running it is fine.

Server-side protocol changes:

  - New CHECK value 'waiting_local_directory' on agent_task_queue.status
    plus a wait_reason TEXT column (migration 109).
  - All cancel / active / counted-as-running / orphan-recovery queries
    expanded to include the new status; FailStaleTasks intentionally
    excludes it (the daemon owns the wait).
  - New SQL MarkAgentTaskWaitingLocalDirectory(id, reason) and a relaxed
    StartAgentTask that accepts both dispatched and
    waiting_local_directory as preconditions (and clears wait_reason on
    the way through).
  - New POST /api/daemon/tasks/{taskId}/wait-local-directory endpoint,
    TaskService.MarkTaskWaitingLocalDirectory broadcaster, and matching
    daemon Client.MarkTaskWaitingLocalDirectory.

Tests cover: path blacklist + R/W enforcement, mutex serialisation +
ctx-cancelled wait, lock handover between two tasks, GC never returns
gcActionClean / gcActionOrphan for local_directory rows (with negative
control for the standard path), and Prepare/Cleanup correctly substitute
+ protect the user's WorkDir.

The desktop UI side (UI for adding a local_directory resource, surfacing
the "等待本地目录" badge) is MUL-2665; the agent-task lifecycle changes
(no branch switch, dirty-tree tolerant, auto-commit) are MUL-2664.

This PR targets the shared MUL-2618 v1 feature branch agent/j/912b8cb1,
not main; the whole v1 will be merged to main together when complete.

* fix(daemon): tighten local_directory status, symlink, cancel handling (MUL-2618)

Address the 3 must-fix items from Elon's review of PR #3274.

1. Status string unified. The server / daemon publish
   `waiting_local_directory`; align views, locales, and the
   pickStageKeys test (PR #3273 had used `waiting_for_directory_release`
   on a placeholder string). Without this, the daemon's wait state
   never reached the pill once the two siblings merged.

2. validateLocalPath now also runs the blacklist against the
   symlink-resolved realpath, with macOS's `/etc` -> `/private/etc`
   redirect handled via `isBlacklistedRealPath` which compares
   canonical forms. Without this, a symlink such as
   `/Users/me/proj/home -> /Users/me` slipped the literal $HOME check
   while every daemon write still landed in the user's home. Tests
   cover symlink-to-home, symlink-to-system-root, and the negative
   case (symlink to a regular subdirectory).

3. acquireLocalDirectoryLockIfNeeded now spins up a cancellation
   watcher inside `onWait` (lazy — the fast path stays free) so the
   gap between dispatch and StartTask responds to server-side cancel
   or row deletion. If the watcher fires while the daemon is parked
   on the path mutex, the lock-wait context is cancelled, Acquire
   returns promptly, and the helper exits silently the same way the
   run-phase poller does. New TestAcquireLocalDirectoryLock_CancelDuringWait
   exercises the path end-to-end with a fake server.

* fix(daemon): unconditional canonical blacklist + Windows drive-root generalisation (MUL-2618)

- validateLocalPath now always runs isBlacklistedRealPath on the
  symlink-resolved path, not only when it differs from absPath. The old
  guard let users type the canonical form of an OS-symlinked banned root
  (e.g. /private/tmp, /private/etc, /private/var on macOS) straight
  through, since EvalSymlinks is a no-op on already-canonical input.
- Windows drive-root rejection moved off the static C/D/E/F enumeration
  onto filepath.VolumeName via a new isDriveRoot helper, so removable /
  network drives mounted at G:..Z: and UNC \\server\share roots are also
  blocked. systemRootBlacklist keeps the well-known C:\ trees only.
- Tests: macOS-only case exercises direct /private/{tmp,etc,var}; a
  new TestIsDriveRoot covers the Windows generalisation (skipped on
  POSIX runners by runtime guard).

* feat(views): wire waiting_local_directory end-to-end in issue UI + presence (MUL-2618)

Connect the daemon-emitted `task:waiting_local_directory` and `task:running`
events through to issue execution log, sticky agent banner, activity indicator,
and agent presence so a parked task is no longer invisible on the issue page.

- Add `waiting_local_directory` to `AgentTask.status` and the typed
  `task:running` / `task:waiting_local_directory` WS event payloads.
- Chat realtime sync writes both new statuses into the pending-task cache so
  the chat StatusPill flips out of a stale `dispatched` frame.
- ExecutionLogSection: count `waiting_local_directory` as active, add tone +
  status label, treat parked tasks the same as dispatched for time anchor /
  transcript visibility / terminate-confirm note.
- AgentLiveCard: subscribe to both new events, rank the parked state between
  dispatched and queued, and surface a "is waiting for the local directory"
  banner with the muted "Clock" treatment used for queued.
- IssueAgentActivityIndicator: route parked tasks into the queued bucket so
  the hover stack and chip stay visible.
- derive-presence: parked tasks count toward `queuedCount` so the agent
  workload chip stays out of `idle` while the daemon waits on the path lock.
- Locales: add `agent_live.is_waiting_local_directory` and
  `execution_log.status_waiting_local_directory` (en + zh-Hans).

* feat(project): enforce one local_directory per (project, daemon) (MUL-2618)

The daemon-side resolver picks the first matching local_directory by
daemon_id, so allowing two rows on the same daemon — even at different
paths — let the agent silently write into whichever sorted first. Tighten
the invariant top to bottom:

- server: `findLocalDirectoryConflict` rejects any second row sharing a
  daemon_id, regardless of `local_path` or label. Bundled-create surface in
  `CreateProject` runs the same daemon-scoped dedupe up front.
- daemon: `findLocalDirectoryAssignment` fails fast when it finds more than
  one row pinned to the current daemon (older API client / direct DB
  writes can still produce that state — refuse to guess).
- desktop UI: hide the "Add local directory" action once the current
  daemon owns a row on this project, with a hint and a defensive toast on
  the call path; foreign-daemon rows stay visible read-only as before.
- Tests:
  * daemon: new `two local_directory rows on this daemon fail fast` /
    `local_directory rows on different daemons coexist` cases.
  * handler: rewrite the legacy `LabelShadow` cases as
    `DaemonScopedConflict` / `BundledLocalDirectoryDaemonConflict` —
    asserts 409 on same-daemon different-path, 201 on per-daemon bundles.

* chore(sqlc): drop stale skills_local in UpdateAgentCustomEnv (MUL-2618)

Follow-up to the main-merge in 0f8e8ca7: the auto-merge preserved most
of main's skills_local revert but kept the column reference inside the
UpdateAgentCustomEnv scanner because that block hadn't been touched by
either side. Re-running `sqlc generate` regenerates the file without
skills_local in this query, matching the rest of the file and the
post-revert schema.

* feat(create-project): binary source picker — repos OR local directory

Turn the create-project dialog's "Repos" pill into a binary Source
picker. A project's source is mutually exclusive: either a set of
GitHub repos (worktree mode, default) or a single local working
directory (local mode, desktop-only). Mirrors the constraint the
backend will enforce next.

Behavior:
- Pill shows the active mode's selection (GitHub icon + repo count, or
  folder icon + local label/path).
- Popover has a 2-tab segmented control at the top; the Local tab is
  hidden entirely on web (local_directory needs a daemon_id).
- Local tab requires the daemon online — amber notice + disabled picker
  when offline, re-renders automatically via useLocalDaemonStatus.
- Switching tabs preserves the other side's stash, but handleSubmit
  only emits the resource matching the active sourceMode, so abandoned
  picks never leak into the created project.

Backend mutual-exclusion validation + the resources-section
conditional-add-button still to come — this PR just unblocks the
dialog so it can be demoed.

668fe99cce fix(cli): drop "Showing N comments." stderr preamble on issue comment list (#3341)
This was the only `list` subcommand that printed a human-readable count
to stderr. Consumers that merge stdout/stderr (agent harnesses, CI
`2>&1`) saw it interleaved with the JSON array on `--output json`, and
in table mode it carried no information the table itself didn't.

The `Next thread cursor` / `Next reply cursor` lines stay — they're
real paging signals the agent runtime reads from stderr.

Closes #3303

df02fcf175 fix(cli): show real MEMBERS count in multica squad list (#3307)
The MEMBERS column was hardcoded to "-" in the table output, so every
squad looked empty even though the backend already returns
`member_count` (and `member_preview`) on each row. `squad get --output
json` exposed the correct data, which is why the bug was cosmetic but
confusing.

Read `member_count` from the response and render it; fall back to "-"
when missing or zero so empty squads stay visually distinct.

Fixes #3304 (MUL-2706).

91506e7f7b refactor(cli): rename daemon status helper and align value column (MUL-2676) (#3275)
- Rename printDaemonStatusTable -> printDaemonStatusReport. The helper
  emits a key/value list, not a table; the old name implied a tabular
  layout that never existed and made the call site read wrong.

- Align the value column dynamically off the widest key. Previously the
  spacing was hard-coded so the static rows (Version/Agents/Workspaces)
  all landed at column 14, but the dynamic "Daemon [profile]" label
  could outgrow that and push only its own value rightward, breaking
  vertical alignment as soon as a profile was active.

- Add negative coverage for cli_version absent / empty (the real
  back-compat contract for older daemons paired with a newer CLI) and a
  test that asserts the value column lines up under a long profile
  label.

bf8a346cf0 feat(runtimes): cascade-archive agents on runtime delete (MUL-2667) (#3266)
* feat(runtimes): cascade-archive agents on runtime delete (MUL-2667)

Replace the bare 409 "cannot delete runtime: it has active agents" with a structured response carrying the blocking agent list, and wire a cascade endpoint that archives those agents, cancels their tasks, pauses dangling autopilots and deletes the runtime in a single transaction. The unified DeleteRuntimeDialog opens directly in cascade mode when the runtime has bound agents, pivots from light to cascade if the strict DELETE refuses with runtime_has_active_agents, and re-prompts when the cascade refuses with runtime_delete_plan_changed (live agent set drifted while the dialog was open). The online-local self-healing rule is preserved at the affordance level (kebab hidden, Diagnostics button disabled with tooltip) and re-checked at confirm time as defence in depth.

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

* fix(runtimes): close cascade race + i18n delete dialog (PR #3266 review)

- Acquire FOR UPDATE on the runtime row at the top of the cascade tx so
  FK-validated agent INSERTs/UPDATEs that would point at this runtime
  block until commit, and lock each currently-active agent row via
  ListActiveAgentsByRuntimeForUpdate so a concurrent archive/move of
  an existing active row also blocks.
- Switch the bulk archive from runtime-keyed (ArchiveAgentsByRuntime)
  to ID-keyed (ArchiveAgentsByIDs), narrowed to the user-confirmed
  expected_active_agent_ids set. Combined with the runtime row lock,
  this guarantees no agent outside the confirmed plan can be silently
  archived between plan-compare and archive even at read-committed.
- Wire delete-runtime-dialog.tsx to runtimes locale via useT(); add
  detail.delete_dialog.{light,cascade} keys (EN with _one/_other
  plurals, zh-Hans _other) covering titles, descriptions, warning,
  notices, checkbox, buttons, table headers, presence labels, and
  toasts. Resolves the i18next/no-literal-string CI failure.
- Locale parity test passes (51 tests). All 4 dialog test cases pass
  unmodified (EN copy preserves original wording). Full views vitest:
  91 files / 792 tests green; full server go test: green.

13f74e651a feat(agents): remove custom_env from agent resources, add audited env endpoint (MUL-2600) (#3209)
* feat(agents): remove custom_env from agent resources, add audited env endpoint (MUL-2600)

The agent resource shape (list / get / create / update / archive /
restore responses + WebSocket events) no longer carries `custom_env`
values. Reads/writes of env now flow exclusively through a dedicated
`/api/agents/{id}/env` endpoint that is owner/admin-only, rejects
agent-actor sessions, applies a "****" sentinel preserve guard on
PUT, and writes a persistent audit row per reveal/update.

Why
- `multica agent list --output json` historically returned plaintext
  `custom_env` for owner/admin callers (the redaction gate gave only
  members the masked map). Any agent token running on the workspace
  inherits its owner's role and could read every other agent's
  secrets just by listing.
- Patching list/get redaction alone (PR #3175 direction) left
  symmetric leaks via mutation responses, WS events, the "reveal"
  path itself (no actor-aware auth), and a `****` overwrite footgun
  on UpdateAgent.

What changed
- Backend: drop `custom_env` from AgentResponse; add coarse
  `has_custom_env` + `custom_env_key_count`. Strip env handling from
  UpdateAgent (silently ignored if sent). Keep CreateAgent's
  custom_env acceptance.
- Backend: new GET/PUT `/api/agents/{id}/env` handlers in
  `internal/handler/agent_env.go`:
  - resolveActor → 403 for agent actors (closes the lateral-movement
    path).
  - Owner/admin role gate via existing helper.
  - PUT honours value == "****" as "preserve existing value".
  - Both write to `activity_log` with `agent_env_revealed` /
    `agent_env_updated` actions. Audit details record key names only,
    never values.
- Daemon claim path (`ClaimAgentTask`) unchanged — `TaskAgentData`
  still carries plaintext env for runtime injection.
- SQL: new `UpdateAgentCustomEnv` query; sqlc regenerated (v1.31.1).
- CLI: new `multica agent env get|set` subcommands. `--custom-env*`
  flags removed from `multica agent update`; the no-fields error
  now points to the new path.
- Frontend: drop env fields from `Agent` + `UpdateAgentRequest`; add
  `getAgentEnv` / `updateAgentEnv` client methods; rewrite env-tab
  to show "N variables configured" + explicit "Reveal & edit"
  button, fetching values only on intentional reveal.
- Locales: parity-safe additions to en + zh-Hans.
- Docs: agents-create.{mdx,zh.mdx} reflect the new threat model and
  endpoint.
- Mobile: schema drops `custom_env` / `custom_env_redacted`, adds
  metadata fields.

Tests
- Handler tests pinned the new invariants: no env in list/get
  responses, owner reveal happy-path + audit row, agent-actor 403,
  `****` sentinel preserves real values, UpdateAgent silently
  ignores `custom_env`, pure `mergeAgentEnv` cases.
- CLI tests pivot to the new flag surface: `agent update` MUST NOT
  expose the env flags; `agent env set` MUST expose
  --custom-env-stdin/--custom-env-file.
- Frontend test fixtures updated; pnpm typecheck / test / lint
  pass cleanly.

This is a breaking API change. Scripts that read `custom_env` from
`/api/agents` must migrate to `GET /api/agents/{id}/env`.

* fix(agents): close actor-spoofing + audit fail-closed in env endpoints (MUL-2600)

Addresses Elon's review of #3209:

* Mint a task-scoped `mat_` token per claim, bound to (agent, task,
  workspace, owner). Daemon injects it into the agent process in place
  of its own credential. Auth middleware authoritatively rebuilds
  X-User-ID / X-Agent-ID / X-Task-ID from the token row and sets
  X-Actor-Source=task_token; that header is server-set only — incoming
  values are stripped before any auth branch runs. resolveActor honors
  the header so an agent that strips X-Agent-ID / X-Task-ID still
  resolves as actor=agent.
* GetAgentEnv / UpdateAgentEnv are now fail-closed on audit-log
  failures: GET refuses to return plaintext, PUT persists inside the
  same tx as the audit row so they commit/roll back together.
* PUT /api/agents/{id} returns 400 when the body carries custom_env
  instead of silently dropping it — directs callers to the audited env
  endpoint.
* Agent actors never see mcp_config, even when the underlying member
  is owner/admin; mutation broadcasts go through a redaction shim so
  WS subscribers don't pick it up either.
* Fix backend test that asserted dense JSON (jsonb::text renders
  whitespace) and frontend test that assumed a unique "Test User"
  match.

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

* fix(agents): close residual MUL-2600 gaps from review (MUL-2600)

Migration 108 FK now correctly references agent_task_queue(id) instead
of the non-existent agent_task table; the previous name blocked CI
backend migrations.

Task-token-authenticated requests can no longer be re-routed at a
different workspace by passing workspace_slug / workspace_id /
?workspace_id / a URL workspace param. ResolveWorkspaceIDFromRequest
and resolveWorkspaceUUID both short-circuit on X-Actor-Source=task_token
and return only the token-bound X-Workspace-ID; buildMiddleware adds a
defence-in-depth 403 if any URL-resolved workspace disagrees with the
token binding.

mcp_config no longer leaks back to agent actors through UpdateAgent /
CreateAgent / ArchiveAgent / RestoreAgent HTTP responses — the same
redactAgentResponseForActor helper that GetAgent/ListAgents use is now
applied to mutation responses too. WS broadcasts were already redacted
via broadcastAgentResponse.

FailTask and every TaskService cancel path (CancelTask /
CancelTasksForIssue / CancelTasksForAgent / CancelTasksByTriggerComment
/ BroadcastCancelledTasks) now eagerly DeleteTaskTokensByTask so the
mat_ token's 24h window doesn't outlive a terminated task. Failure is
non-fatal — the FK cascade and expiry remain durable guards.

Doc-only: clarify that PUT /api/agents/{id} now hard-rejects bodies
that carry custom_env (was previously "silently ignores").

Tests:
- middleware: TestResolveWorkspaceIDFromRequest gains a task_token
  case asserting client-supplied slug/id/query cannot override the
  bound workspace.
- handler: TestUpdateAgent_RedactsMcpConfigForAgentActor and
  TestUpdateAgent_KeepsMcpConfigForMemberActor pin the mutation-
  response redaction contract per actor type.

* fix(agents): match redacted mcp_config as JSON null, not Go nil (MUL-2600)

`AgentResponse.McpConfig` is `json.RawMessage` without `omitempty`, so
the redacted response serialises as `"mcp_config": null`. On decode,
`json.RawMessage` keeps the literal bytes `null` rather than collapsing
to Go nil, which made the assertion fire on a non-leak.

The product contract (field always present, distinguished from "no
config" via `mcp_config_redacted`) is intentional, so adjust the test
to check for "no secret-bearing content" instead of weakening the
contract via `omitempty`.

c967ae0e0e feat(issues): platform-owned parent notify on child done (MUL-2538) (#3055)
* feat(issues): platform-owned parent notify on child done (MUL-2538)

When a child issue transitions from a non-done status into `done` and has
an open parent, the server now posts a top-level platform-generated
comment on the parent itself. Replaces the agent-prompt rule shipped in
PR #2918, which produced self-mention loops, planner ping-pong, and
accidental `MUL-` prefix hardcoding because the agent did not always know
the workspace prefix.

- Migration 107 widens `comment.author_type` to allow `system`; the
  zero UUID is used as the sentinel `author_id` (the column stays NOT
  NULL, callers branch on `author_type === 'system'`).
- `Handler.notifyParentOfChildDone` fires from both `UpdateIssue` and
  `BatchUpdateIssues`. Guards: prev status != done, new status == done,
  parent set, parent not in `done`/`cancelled`. Bypasses the
  CreateComment HTTP path so the assignee on_comment trigger and the
  mention-trigger paths do not fire — the comment content carries only
  the safe issue mention for the child, no `mention://agent/...` /
  `mention://member/...` / `mention://squad/...` links.
- `runtime_config.go` downgrades the Parent/Sub-issue Protocol rule 1
  to an explicit "do NOT post one yourself" guardrail; rule 2 (sub-issue
  creation `--status todo` vs `backlog`) is unchanged.
- New handler test exercises the happy path, idempotency, reopen+done,
  parent done/cancelled guards, and the no-parent case. Runtime-config
  tests reassert the new wording and the banned strings from the prior
  revision.

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

* fix(issues): isolate system comments + wire GH merge path (MUL-2538)

Addresses the two must-fix items from the PR #3055 second review:

1. The platform-generated `comment:created` event (author_type='system')
   was running through the generic comment listeners, which (a) tried to
   subscribe the zero-UUID author and (b) parsed @mentions from the body
   for inbox notifications. Both subscriber_listeners and
   notification_listeners now early-return on author_type='system' so the
   event becomes a pure WS broadcast for the timeline — no inbox rows,
   no transcluded-mention attack surface.

2. advanceIssueToDone (the GitHub merge auto-done path) only published
   issue:updated and skipped notifyParentOfChildDone, so a child closed
   via merged PR — the dominant completion path — left the parent
   silent. The helper is now invoked on the same prev/updated pair, with
   the existing guards (transition + parent state) protecting double-fire.

Tests:
- New cmd/server/notification_listeners_test:
  TestNotification_SystemCommentSkipsInboxAndMentions (parent subscribers
  and smuggled @mention targets stay quiet),
  TestSubscriberSystemCommentDoesNotSubscribe (zero-UUID never reaches
  AddIssueSubscriber).
- New internal/handler/github_test:
  TestWebhook_MergedPR_ChildWithParent_NotifiesParent fires a real
  pull_request closed-merged webhook against a child and asserts the
  parent receives exactly one safe system comment with the workspace's
  real identifier (no `mention://agent|member|squad` links).

* fix(runtime): drop parent-notification guidance from agent brief (MUL-2538)

Per Bohan's product call on PR #3055: the platform now owns the
child-done parent notification, so the runtime brief should not mention
the parent-comment path at all — not as an instruction, not as a "do
not do it" guardrail. The previous revision kept rule 1 of the Parent /
Sub-issue Protocol as a "Do NOT post your own parent-notification
comment." sentence; that still puts the concept in front of the agent
every run, which is exactly what we are trying to avoid.

What changes:
- Delete the "Parent / Sub-issue Protocol" preamble and rule 1 from
  buildMetaSkillContent. The remaining content — the `--status todo`
  vs `--status backlog` rule for creating sub-issues — now lives in a
  dedicated `## Sub-issue Creation` section, since the parent/child
  framing it previously sat under is gone.
- The system comment on the parent stays exactly as in 366f6e2: the
  agent simply does not need to know about it.

Tests:
- runtime_config_test.go is rewritten around the new section name and
  the wider "no parent-notification guidance" canary; the banned list
  now covers both the original PR #2918 wording and the intermediate
  "do NOT post one" wording.

System comment UI: the frontend already renders `author_type === "system"`
with author name "Multica" (`useActorName`) and the MulticaIcon avatar
(`ActorAvatar` via `isSystem`), matching Bohan's "looks like a normal
comment, author is multica + multica logo" requirement — no frontend
changes needed.

1c91c2a3b2 security(db): scope DELETE/UpdateIssueStatus by workspace_id (defense-in-depth) (#3027)
* fix(security): scope DELETE/UpdateIssueStatus by workspace_id

Add workspace_id to the WHERE clause of DeleteIssue, DeleteComment,
DeleteProject, DeleteSkill, DeleteChatSession, and UpdateIssueStatus
as SQL-layer defense-in-depth.

Handler loaders (loadIssueForUser / loadSkillForUser / etc.) already
enforce workspace membership today, so this is not patching a known
live vuln. But the tenant invariant is currently a handler-layer
guarantee — a future loader bypass or a new caller skipping the
loader would be silently catastrophic. Making workspace_id part of
the SQL identity collapses the trust surface to the schema itself:
forging a sibling-workspace UUID becomes ErrNoRows instead of a
cross-tenant write.

Reference: incident #1661 (util.ParseUUID silent zero UUID returning
204 on a DELETE that matched zero rows) — same class of failure,
prevented at a different layer.

Scope:
- 5 DELETE queries: issue, comment, project, skill, chat_session
- 1 simple UPDATE: UpdateIssueStatus (2 narg, no SET ordering risk)
- All callers updated (handlers, service, runtime sweeper fallback)

Multi-narg UPDATE queries (UpdateIssue, UpdateProject, UpdateSkill,
UpdateComment, UpdateChatSession*) are deferred to a follow-up to
keep this change reviewable: each needs its narg pinning shifted
and per-caller verification.

sqlc was regenerated by hand (no local sqlc toolchain); CI's
backend job is the authoritative compile check.

* test(security): add workspace_scope_guard regression test

Locks in the SQL-layer tenant guard added in this PR. For each of the 6
scoped queries (DeleteIssue, DeleteComment, DeleteProject, DeleteSkill,
DeleteChatSession, UpdateIssueStatus), creates the resource in workspace
A, invokes the query with a foreign workspace UUID, and asserts the row
is untouched (0 rows affected with no error for :exec; pgx.ErrNoRows for
:one). A future refactor that drops the workspace_id arg from any of
these queries will now fail loudly instead of silently regressing.

Includes a sanity sub-test that the in-workspace path still mutates, so
a buggy guard that returns no-op for every call would not pass.

7984606eed feat(landing): add Contact Sales page and inquiry endpoint (MUL-2493) (#2988)
* feat(landing): add Contact Sales page and inquiry endpoint (MUL-2493)

Adds a public `/contact-sales` marketing page with a needs-discovery form
modelled on the design reference attached to MUL-2493 — first/last name,
business email (with free-provider rejection), company name + size,
country/region, intended use case, and a free-text goals field, plus the
two consent checkboxes from the reference.

Submissions hit a new public `POST /api/contact-sales` endpoint with
per-IP rate limiting (Redis-backed via the existing RateLimit middleware,
configurable through `RATE_LIMIT_CONTACT_SALES`) and a per-email hourly
cap so a single business address can't be used as a flood channel after
one valid pass. The inquiry is stored in a new `contact_sales_inquiry`
table; analytics fires a `contact_sales_submitted` PostHog event with
only the closed-enum dimensions (size, country, use case) — the free-text
goals stay in the DB and are never broadcast.

The page is linked from the landing header (md+) and the footer's Company
column, in both English and Simplified Chinese. The reserved-slug list is
updated so a workspace named `contact-sales` can't shadow the route.

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

* fix(landing): canonicalize business email and tighten contact-sales form (MUL-2493)

- Parse the submitted email with net/mail and run the free-email
  block-list against the canonical addr.Address, so a display-name
  form like `Ada <ada@gmail.com>` can no longer slip past the gate
  (the raw string had domain `gmail.com>`, which wasn't blocked).
  Adds regression tests covering the display-name bypass and the
  canonicalization helper.
- Drop noValidate from the contact-sales form so the browser's
  native required / email / select checks fire before submit;
  the JS-side free-email warning still runs as a UX guard.
- Update success copy ("respond within three business days") in
  EN and ZH plus the page metadata.

fbd965e5bf feat(onboarding): v3 — thin server, frontend-orchestrated welcome (#3008)
* feat(onboarding): Multica Helper as general workspace assistant + blocking modal

Reshape Multica Helper from an onboarding-only guide into the workspace's
general-purpose AI assistant. The agent's permanent identity (injected as
`## Agent Identity` into every task's CLAUDE.md / AGENTS.md / GEMINI.md
via execenv.InjectRuntimeConfig) is rewritten to three sections that don't
overlap with what the brief already provides:

  - Who I am (built-in workspace assistant, not onboarding-only)
  - What Multica is + docs/source/issues URLs as knowledge sources
  - What I can do (CLI = manifest, `multica --help` is the source of truth)
  - Tone (concise, like a colleague, match user's language)

Bootstrap moves out of the in-flow Step 4. Runtime step now exits the
onboarding shell with no bootstrap call; a blocking OnboardingHelperModal
mounts inside the workspace layout (web + desktop) and gates purely on
`me.onboarded_at == null`. The user picks one of three starter prompts
(intro / assign / second_agent) and the modal calls
BootstrapOnboardingRuntime with a new optional `starter_prompt` field that
becomes the seeded onboarding issue's description.

Side effects required to make `onboarded_at == null` an honest signal:

  - CreateWorkspace no longer marks onboarded (was atomic with CreateMember).
    The "member exists ⟹ onboarded_at != null" invariant is intentionally
    broken; guards (useDashboardGuard / desktop App.tsx) already tolerate
    this — comments updated to reflect the new contract.
  - AcceptInvitation still marks (invitee skips the modal in someone
    else's workspace). Code comment added warning future removers.
  - resolvePostAuthDestination flips to workspace-presence-first: a user
    with a workspace lands in it regardless of `onboarded_at`, so the
    modal can pick up an interrupted setup on relogin.

Other backend changes:
  - `onboardingAssistantDescription` rewritten ("Built-in workspace assistant…")
  - `onboardingAssistantInstructions` rewritten to the 3-section identity
  - `bootstrapOnboardingRuntimeRequest.StarterPrompt` (optional, 2 KiB rune
    cap, empty-falls-back-to onboardingIssueDescription)

Frontend changes:
  - Delete `packages/views/onboarding/steps/step-teammate.tsx` (no longer a
    persisted step)
  - `ONBOARDING_STEP_ORDER` and `OnboardingStep` type drop `"teammate"`
  - `handleRuntimeNext` exits via `onComplete(workspace, undefined)` — no
    bootstrap, `onboarded_at` stays NULL so the modal fires
  - Runtime step next-button copy → "Start exploring" / "开始探索"
  - New `packages/views/workspace/onboarding-helper-modal.tsx`:
    Base UI Dialog, dismissible=false, three localized cards, mutation
    invalidates agents + issues queries then navigates to the seeded issue
  - Mounted in both `apps/web/app/[workspaceSlug]/layout.tsx` and
    `apps/desktop/src/renderer/src/components/workspace-route-layout.tsx`

Tests:
  - Backend: TestBootstrapOnboardingRuntime_{With,No}StarterPrompt and
    TestCreateWorkspace_DoesNotMarkOnboarded
  - Frontend: onboarding-helper-modal.test.tsx covers all four gating
    conditions, three-card behavior, mutation pending state, and the
    "no close button" invariant

Compatibility:
  - Already-onboarded users: zero impact (modal can't fire)
  - Invitees: AcceptInvitation still marks → modal can't fire
  - Skip-runtime path: BootstrapOnboardingNoRuntime still marks → modal can't fire
  - Old desktop / web clients: legacy teammate-step path keeps working
    (bootstrap accepts missing starter_prompt) — the new modal only fires
    on the new frontend bundle
  - Avatar SVG kept (asterisk variant) — no migration of existing Helper
    agents, only newly-created Helpers pick up the new instructions/description

On desktop, App.tsx auto-creates a tab pointing at the user's first
workspace as soon as workspaces.length flips from 0 → 1 (during onboarding
Step 2). The new tab mounts WorkspaceRouteLayout under the overlay,
which mounts OnboardingHelperModal. The modal's Portal renders to
document.body — appearing AFTER the WindowOverlay in DOM order, so its
z-50 wins and the modal floats in front of the still-active onboarding
Step 3 (runtime).

Suppress the modal whenever any WindowOverlay is active. When the overlay
closes (onComplete fires after the user finishes onboarding), the modal
re-evaluates `me.onboarded_at == null` and pops on its own.

Web is unaffected (onboarding flow lives at /onboarding, not under
/[workspaceSlug]/, so WorkspaceRouteLayout never mounts during the
onboarding flow).

* docs(onboarding): add v2 refactor plan

Captures the design + 8-step implementation order for collapsing the
onboarding state machine: single mark-onboarded entry point, persisted
Step 3 user choice, dumb Modal, single install-runtime seed call site.
Includes old-user compatibility analysis (4 existing gates) and per-PR
risk/rollback.

* feat(db): persist Step 3 runtime choice on user record (MUL-onboarding-v2)

Adds onboarding_runtime_id UUID NULL + onboarding_runtime_skipped BOOLEAN
columns to "user" and the CHECK constraint enforcing the 3-state machine
(unset / picked-runtime / explicit-skip; the fourth combination is
forbidden). ON DELETE SET NULL on the FK so a deleted runtime degrades
to "unset" rather than dangling.

PatchUserOnboarding gains the two narg fields plus CASE expressions that
collapse the runtime/skipped pair atomically — a follow-up PATCH that
flips one side now clears the other in the same statement, instead of
preserving it via per-field COALESCE and tripping the CHECK constraint.

Backwards compatible for existing users: both new fields default to
(NULL, false), which is the "unset" leaf of the state machine, and four
upstream gates on me.onboarded_at != null already short-circuit the
new fields' readers for everyone who's already onboarded.

* refactor(server): collapse onboarding side effects to service layer

Introduces OnboardingService.MarkComplete and
WorkspaceContentService.{Ensure,Seed}InstallRuntimeIssue as the single
authorities for the two onboarding side effects that used to be
duplicated across four handlers:

  - MarkUserOnboarded + claim starter_content_state +
    optional install-runtime fallback seed: was inline in
    BootstrapOnboardingRuntime, BootstrapOnboardingNoRuntime,
    AcceptInvitation, and CompleteOnboarding.
  - install-runtime issue seeding: was inline in CreateWorkspace and
    AcceptInvitation as a "no runtime yet" fallback.

After this refactor:
  - MarkUserOnboarded is called from exactly one place (the service).
  - install-runtime issue is seeded from exactly one place (the service).
  - CreateWorkspace deliberately does not seed — the new
    /ensure-onboarding-content endpoint (also added here) lets the
    workspace-entry init component request the seed on first mount, so
    workspaces created but never opened don't accumulate stale issues.
  - The PatchOnboarding handler now accepts the new runtime_id /
    runtime_skipped fields and rejects (uuid, skipped=true) up front.
  - UserResponse exposes the two new persisted fields so the frontend
    can read them off `me` without an extra round-trip.

Handler-side tests added: TestPatchOnboarding_RuntimeChoiceSwitch (the
explicit cross-request switch path that the original COALESCE design
would have 500'd on) + TestPatchOnboarding_PreserveUntouched.

Old handler-local file no_runtime_issue.go is deleted; its content
moved to service/workspace_content.go with the helpers exported.

* feat(core): API + types for persisted onboarding runtime choice

User type / Zod schema gain onboarding_runtime_id (string | null) and
onboarding_runtime_skipped (boolean); EMPTY_USER + test fixture updated
to match. api.patchOnboarding accepts the new optional fields and the
new api.ensureOnboardingContent endpoint is wired so the workspace
shell can request the fallback seed.

Two new store helpers — recordOnboardingRuntimeChoice(runtimeId) and
recordOnboardingRuntimeSkipped() — replace the prior pattern of
Step 3 calling bootstrap directly. They PATCH the user's choice, sync
the auth store, and return. Mutually exclusive on the server side via
the CHECK constraint; the client just ships one intent at a time.

* feat(workspace): WorkspaceOnboardingInit single decision point + dumb Modal

Replaces OnboardingHelperModal's self-gating render path with a 4-branch
dispatcher that runs once on workspace-shell mount:

  branch 0  me.onboarded_at != null         → ensure install-runtime issue
                                              fallback, render nothing
  branch 1  me.onboarding_runtime_skipped   → SkipBootstrapping component:
                                              loading veil → bootstrap →
                                              navigate. On failure shows
                                              a Retry UI instead of
                                              silently freezing the veil
  branch 2  me.onboarding_runtime_id        → render Modal with the
                                              runtime id from `me` (no
                                              internal list query)
  branch 3  (none of the above)             → useEffect navigate back to
                                              /onboarding so the user
                                              walks Step 3 again

The Modal itself is now a dumb component — receives `workspace` and
`runtimeId` as props, no internal gates, no runtimeListOptions query.
Tests rewritten to cover the props-driven render + pick-card paths;
the prior gating tests move into the new
workspace-onboarding-init.test.tsx alongside the M2 retry-on-failure
behaviour.

Mounted in both apps/web/app/[workspaceSlug]/layout.tsx and the desktop
workspace-route-layout. Desktop keeps its `!overlayActive` suppression
guard so the init doesn't portal-jump in front of an active
WindowOverlay.

* feat(onboarding): Step 3 records user choice instead of calling bootstrap

handleRuntimeNext now PATCHes the user's pick (recordOnboardingRuntime
{Choice,Skipped}) and navigates straight into the workspace shell. The
workspace-entry WorkspaceOnboardingInit reads the persisted choice off
`me` and runs the appropriate branch — Step 3 is pure intent capture
with zero side effects on its own.

PATCH must succeed before navigation: if it fails the user stays on
Step 3 with a toast, because navigating with no persisted intent would
land them in WorkspaceOnboardingInit's branch 3 "no decision yet" rescue
and trigger a redirect loop back to /onboarding.

The prior asymmetry (Connect deferred bootstrap to the workspace, Skip
ran bootstrap inline) is gone — both paths defer to the workspace
shell now.

* feat(onboarding): v3 — thin server, frontend-orchestrated welcome

Collapse v2's persisted runtime-choice fields + 4-branch dispatcher +
OnboardingService/WorkspaceContentService stack down to a single rule:
`onboarded_at` is the only state field, layout hard-gates on it, and the
welcome experience after Step 3 is owned entirely by the frontend.

V3 flow
- Step 3 button: await POST /api/me/onboarding/complete (mark only) +
  park a transient signal in `useWelcomeStore` + navigate
- Workspace layout: hard gate `onboarded_at == null` -> /onboarding
- `<WelcomeAfterOnboarding />` reads the welcome-store signal:
  - runtime path: find-or-create Multica Helper via generic createAgent
    with bilingual instructions from `templates/helper-instructions.ts`,
    blocking modal with 3 starter cards, pick -> createIssue + navigate
  - skip path: provision install-runtime (in_progress) -> agent-guide
    (todo, body embeds install-runtime mention chip) -> follow-up comment
    on install-runtime mentioning agent-guide; then pop celebration
    modal with 🎉 emoji pop animation, 2 read-only preview cards, single
    [Got it] CTA that navigates to install-runtime

Server cleanup
- Drop OnboardingService, WorkspaceContentService, v2 runtime-choice
  columns/CHECK on user, EnsureOnboardingContent endpoint
- CompleteOnboarding/AcceptInvitation call qtx.MarkUserOnboarded
  directly (no service indirection)
- BootstrapOnboardingRuntime / BootstrapOnboardingNoRuntime kept as a
  deprecation shim in onboarding_shim.go for desktop < v3 during the
  rollout window — handlers inlined to qtx.* calls, no service layer

Localization
- Persisted strings (issue titles/bodies, Helper instructions/
  description, comment prefix) live as TS const `{en, zh}` maps in
  `packages/views/onboarding/templates/` — i18n bundle staleness can no
  longer write raw key paths into DB
- UI-rendered strings (modal copy, status chips, buttons) stay in
  `packages/views/locales/{en,zh-Hans}/onboarding.json`
- Language picked from live `i18n.language` (not `me.language`, which is
  null for new users until they pick a preference)

Race protection
- Module-level promise dedupe (`findOrCreateHelper`, `seedIssueDeduped`,
  `postCommentDeduped`) so React StrictMode double-mount can't fire two
  parallel API calls that the server would then 409

Cross-references between the two skip-path issues render via Multica's
mention-chip protocol `[<identifier>](mention://issue/<uuid>)` so they
match the styled IssueChip pills used elsewhere.

* feat(onboarding): welcome-after-onboarding modal redesign + cross-user safety

Welcome modal polish (the post-Step-3 surface this branch already
introduced):

Runtime path
- Helper avatar replaces the bouncy 🎉 hero; tone-down animation to
  fade. New copy: "Hi, welcome to Multica / I'm your first Agent
  assistant" + capability hint sentence so users discover assignment +
  chat from the first screen.
- Cards changed from "click = submit" to multi-select with the existing
  border-primary + ring selection pattern used by compact-runtime-row;
  bottom CTA "Assign N tasks to me →" appears only with N>0.
- New starter cards: intro / tour / welcome_page (the last one tells
  Helper to paste an HTML welcome page into the issue comment — works
  on any runtime regardless of fs access).
- Success state added between createIssue and navigation: 🎉 +
  "All set!" + "Sit tight  — your {agentName} is on it" + inbox/chat
  hints, single [Got it] button.
- Title/prompt for starter cards now live in TS const
  HELPER_STARTER_PROMPTS (persisted to DB — must not depend on i18n
  bundle being loaded); subtitle stays in onboarding.json.

Skip path
- Body restructured into three independent ```md blocks (Name /
  Description / Instructions) so each picks up the markdown renderer's
  per-block copy button — no manual extraction.
- ZH body now embeds the ZH Helper Description + Instructions (was
  Chinese-around-English-block).
- Follow-up comment uses Multica's mention-chip protocol
  [identifier](mention://issue/uuid) so it renders as the styled
  IssueChip pill.
- Issue titles bilingual with "Step 1 / Step 2" prefix.

Cross-user / cross-workspace safety (code review feedback)
- web onLogout + desktop handleDaemonLogout now call
  useWelcomeStore.reset() so user B logging into the same browser
  doesn't inherit user A's signal.
- WelcomeAfterOnboarding gates on
  currentWorkspace.id === signal.workspaceId — prevents firing the
  modal in workspace B when the signal was parked for workspace A
  (desktop multi-tab, back/forward, deep-link).
- Module-level promise dedupes (pendingHelperSetup,
  pendingIssueSeed, pendingCommentSeed) for the three API calls so
  React 18+ StrictMode dev double-mount can't race-create duplicates.

Other small fixes carried in this commit
- Helper instructions / agent description / starter card titles all
  read i18n.language (not me.language, which is null for new users
  who haven't picked a UI language preference yet).
- Reverted welcome-emoji-pop animation to a small fade for the runtime
  avatar (kept the bouncy variant for the skip 🎉 hero where the
  celebration is the whole point).
- Removed the duplicate 🎉 from the skip modal title (kept the hero
  one only).

* fix(views): i18n hardcoded "Close" in welcome FullScreenError

CI lint (i18next/no-literal-string) blocked on a literal "Close" string
inside `FullScreenError` — surfaced as a nit in the original code
review but missed in the merge. Add `error_close` to onboarding.json
(EN: "Close" / ZH: "关闭") and thread it through as a `closeLabel`
prop, matching the existing `retryLabel` plumbing.

0c767c0052 feat(issues): per-issue metadata KV (MUL-2017) (#2845)
* feat(issues): per-issue metadata KV (MUL-2017)

Adds a small JSONB KV map to every issue for agent pipeline state (attempts,
PR number, pipeline status, ...). Keys match a narrow regex, values are
primitives (string / number / bool), capped at 50 keys per issue and 8KB
per blob. Defense-in-depth via two CHECK constraints (object shape + size).

All mutations are single-key atomic (jsonb_set / `- key`). `UpdateIssue`
intentionally does NOT touch metadata: a whole-blob overwrite would race
with concurrent agent writes.

  GET    /api/issues/:id/metadata
  PUT    /api/issues/:id/metadata/:key   body: { "value": <primitive> }
  DELETE /api/issues/:id/metadata/:key

Containment filter on list: GET /api/issues?metadata=<json-object> uses
PG `@>` against a `jsonb_path_ops` GIN index. Mirrored across ListIssues,
CountIssues, ListOpenIssues, and the hand-rolled ListGroupedIssues SQL so
CLI/API and UI grouped views stay consistent.

CLI: multica issue metadata {list,get,set,delete}
  multica issue list --metadata key=value (repeatable, AND)
  set has --type to override the default value-sniffing

* fix(issues): metadata test bugs + wire realtime + read-only display (MUL-2017)

- Fix two failing handler tests blocking backend CI:
  - reset decode target after delete so map merge does not mask removal
  - url.PathEscape the key segment so spaces no longer panic NewRequest
- Wire issue_metadata:changed end to end so the detail / list / my-issues
  caches stay in sync with set/delete events (other tabs, CLI writes).
- Add a read-only Metadata strip to the issue detail sidebar; hidden when
  the issue has no keys so it stays quiet in the common case.

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

* feat(runtime): teach agents to read/write issue metadata (MUL-2017)

Add an `## Issue Metadata` section to the runtime brief plus a
`metadata list` step on entry and a `metadata set`/`delete` step on
exit. Section only emits when the task carries an issue id (comment- or
assignment-triggered); chat / quick-create / run-only autopilot stay
clean so they don't fire failing CLI calls.

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

* fix(issues): bump metadata migration to 105 and drop attempts as example (MUL-2017)

main is now at 104_drop_runtime_timezone; the migrator picks
LatestVersion() by sorted filename, so a slot before the tail would
let DBs that have already run 099–104 think they're up-to-date while
the issue.metadata column is missing — runtime would then fail with
column does not exist. Renumbering to 105 puts the migration at the
tail and forces it to run.

Also drop attempts as a positive example across docs/code comments and
test fixtures — the runtime instruction prompt already lists it under
"What NOT to pin" (runtime bookkeeping). Replace with pr_number, which
is in the recommended-keys set, so docs/tests speak the same language
as the prompt.
