60048172a7 fix(lark): ingest inbound images and videos as chat attachments (MUL-4934) (#5580)
* fix: ingest feishu media as chat attachments

* fix: ingest feishu post embedded media

* fix(lark): make inbound media retries safe

* fix lark media resource limit

* fix(lark): move inbound media off ack path

* fix(channel): make inbound media runs durable

* fix(channel): close enqueue-vs-append race on media deferral

EnqueueChatTask read the session-wide media deadline in one statement and
sealed the input batch in a later one. Under READ COMMITTED a media message
committing between the two got sealed into a task the deadline read had
already decided was 'queued', so the daemon could claim it before its
attachment bound — the agent received the bare placeholder, and the later
media-ready promotion was a no-op against a non-deferred task.

After the seal, re-derive the deferral from the sealed batch itself in the
same transaction (DeferChatTaskForSealedPendingMedia): if any sealed message
still carries an unexpired media marker, flip the task to deferred with
fire_at aligned to the latest marker. The existing post-commit promote fence
already covers the opposite direction (marker cleared mid-transaction).

Adds a deterministic regression test that injects the media append between
the deadline read and the seal via a wrapped pgx.Tx.

* fix(channel): keep committed chat task out of enqueue error path

The post-commit media-ready fence returned its error from EnqueueChatTask
even though the deferred task was already durably committed. The router
flush treats any enqueue error as "no task exists": it clears the typing
indicator and logs an enqueue failure while the run still happens at its
fire_at deadline. Log the fence failure instead — the claim-path deferred
promoter re-queues the task regardless.

* fix(channel): cap global media resolution concurrency

Media jobs were serialized per session but unbounded across sessions: a
burst could open arbitrarily many concurrent 45s Lark downloads, and each
unknown-length upload may buffer up to the 100 MiB resource cap in memory.
Gate resolveAndBindMedia behind a global slot semaphore (default 8,
RouterConfig.MediaConcurrency). Per-session ordering is unchanged; on
shutdown a job cancelled while waiting for a slot proceeds straight to the
bounded DB finalize so marker clearing stays prompt. Also document that the
per-message media budget spans queue/slot waits (it must match the
persisted fire_at) and why timed-out uploads cannot leak unbounded orphans.

* fix(chat): keep channel-sealed user messages on task cancel

Sealing the channel input batch stamps task_id onto channel user
messages, which exposed them to the cancel draft-restore path: an
empty-transcript cancel would DeleteUserChatMessageByTask the sealed
Feishu/Slack messages and detach their attachments. Those messages are
the durable record of what the platform sender wrote — the sender has
no Multica composer to restore a draft into.

Gate the restore-delete on ChatSessionHasChannelBinding in both the
synchronous finalize and the deferred finalize (the latter covers
markers left by an older replica during a rolling deploy); a bound
session now settles as "Stopped." instead.

* fix(channel): skip the media pipeline for messages without media

Every inbound message on a Media-enabled platform persisted a 45s
media deadline and queued a resolution job, so a plain text message
could wait behind the global media semaphore (its task deferred while
other sessions download 100 MiB videos) and a crash between append and
clear delayed a pure-text run to the full 45s fallback.

Add MediaResolver.HasMedia — a pure in-memory probe the Router calls
on the ACK path — and only persist the deadline / enqueue the job when
the message actually references platform media. The Feishu resolver
decodes the already-received payload and reports standalone image or
video keys and post-embedded img/media spans.

* fix(chat): gate cancel restore on immutable channel provenance

The previous guard keyed the cancel restore-delete off
ChatSessionHasChannelBinding, but a binding only proves routing exists
right now: archiving a session and rebinding an installation both
delete the binding while preserving chat history, so a still-cancellable
sealed task could again restore-delete the original inbound messages.

Persist provenance on the message instead: migration 203 adds
chat_message.channel_ingested, stamped inside the channel append
transaction and never mutated, and both cancel finalize paths now gate
on TaskHasChannelIngestedMessages over the task's sealed batch. The
binding-existence query is removed. Regression tests cover ingest ->
archive/unbind -> cancel for a queued and a started task.

* fix(channel): reclaim media uploads that never gain an attachment row

Deadline expiry dropped already-resolved refs and a BindMedia failure
was log-only, leaving uploaded objects with no attachment row and no
reclaim path — the dedup mark commits with the message before media
runs, so a redelivery is dropped as a duplicate and never re-resolves
(and thus never overwrites) those keys, and workspace/session deletion
only enumerates the attachment table.

Add MediaResolver.DiscardMedia — a best-effort delete by StorageKey —
and call it from both failure paths in resolveAndBindMedia. The Feishu
resolver forwards to the storage backend's Delete. Tests cover a
partial upload discarded at the deadline, discard on bind failure, and
key-level deletion in the resolver.

* docs(server): refresh comments stale after detached media ingestion

Channel tasks now seal a self-owned input batch, media ingestion is no
longer out of scope for the flattener, and MediaRefs are filled by the
detached resolver after append rather than by feishuChannel pre-engine.

* fix(chat): stop keying channel empty-completion silence off chat_input_task_id

Sealing gave channel tasks a self input-owner, which broke
writeChatCompletionOutcome's discriminator: it treated any owned task
as direct, so an empty channel completion wrote the no_response
fallback row and the outbound patcher — which forwards any non-empty
chat:done content verbatim — pushed the English fallback body to
Feishu/Slack, violating the MUL-4351 contract.

Silence is now decided by the immutable channel_ingested provenance of
the task's input batch, looked up by the batch OWNER id
(chat_input_task_id): auto-retry clones inherit the owner while their
sealed messages stay tagged with the parent's id, so keying off the
task's own id would misread a channel retry as direct. The cancel-path
provenance gates switch to the same owner key via chatInputOwnerID.
chat_input_task_id is back to meaning only "input batch owner".

* chore(migrations): renumber to 203/204 after upstream took 202

Upstream main merged 202_runtime_profile_add_qwen while this branch
held 202/203, tripping TestMigrationNumericPrefixesStayUniqueAfterLegacySet
on the CI merge tree. channel_media_pending becomes 203 and
channel_ingested becomes 204; no content changes.

* fix(channels): gate outbound delivery on channel provenance, not owner

Merging main brought #5645 (keep direct chat replies in Multica),
whose outbound gate assumed channel tasks leave chat_input_task_id
NULL. Sealed channel tasks own an input batch too, so on the merge
tree every channel reply and failure notice was classified as direct
and silently dropped — agents stopped replying in Feishu/Slack.

Both outbound gates now call engine.TaskInputIsChannelIngested: a NULL
owner keeps #5645's deliver-by-default for pre-sealing tasks, an owned
batch delivers only when it carries the immutable channel_ingested
stamp (keyed by the owner id, so auto-retry clones inherit the
verdict). Direct replies stay in Multica; sealed channel replies reach
the platform. Tests cover both directions on both platforms.

* fix(channel): discard media orphans on a fresh context, after finalize

DiscardMedia shared finalizeCtx with BindMedia, so a bind that failed
because the finalize deadline expired handed the storage deletes an
already-dead context — the compensation silently no-opped and the
orphans leaked anyway. The deadline path also ran S3 deletes before
the marker clear, eating the same 5s budget the user-facing
bind/promotion needed.

Collect the refs from both failure paths, run bind + promotion on the
finalize budget first, then delete on a fresh discard context. The
bind-failure test now pins that discard receives a live context.

* fix(channel): compensate result-uncertain media uploads and commits

The compensation protocol treated "the call returned an error" as "the
side effect did not happen", which is wrong in both directions across
the result-uncertain windows:

- An upload error can follow a server-side write (lost response,
  deadline mid-write). The attempted key never reached the router, so
  nothing could reclaim it and dedup guarantees no re-resolve. The
  resolver now idempotently deletes the deterministic key on a fresh
  budget right at the failure site.

- A commit error is not a rollback guarantee: a lost ack can report
  failure after Postgres durably committed the attachment rows, and
  the router's discard would then delete objects those rows reference.
  BindMediaRefs now converges the ambiguity on a fresh budget — any of
  the batch's URLs present proves the atomic commit landed (bind
  reports success); none proves the rollback (discard stays safe); a
  failed verification returns ErrMediaBindResultUnknown and the router
  keeps the uploads, preferring a rare orphan over a broken attachment.

Fault-injection coverage: an upload error deletes the attempted key; a
lost-ack commit keeps the bound attachment and reports success; a
verified rollback stays a discardable error; the router keeps uploads
on the unknown-outcome sentinel.

* feat(channel): replace inline media compensation with an intent ledger and reconciler

Inline best-effort compensation cannot answer "did my side effect
happen?" at the moment it needs the answer — the DELETE/PUT reordering
and the empty-read-vs-in-flight-COMMIT gaps were both instances of the
same two-system atomicity problem. Persist the intent instead and let
an asynchronous reconciler settle it:

- channel_media_pending_object (migration 214; claim index 215 as its
  own single-statement CONCURRENTLY migration): a state machine row
  ('pending' -> 'deleting') with lease, attempt, and backoff columns.
- The resolver upserts the row BEFORE each PUT, state-guarded so a key
  the reconciler owns is never resurrected (the resource is skipped).
  ObjectURL is a pure function of configuration, so the row carries the
  attachment URL pre-upload.
- BindMediaRefs deletes the batch's rows INSIDE the attachment-insert
  transaction: commit landed <=> intents gone, atomically, so an
  ambiguous COMMIT never needs adjudication. A key already claimed to
  'deleting' is skipped (placeholder stays).
- Nothing is ever deleted inline. The reconciler — an independent
  worker so storage latency cannot starve other sweepers — claims due
  rows ('pending' past the settle delay, or expired leases) under a
  fresh lease, checks for a durable attachment reference only AFTER the
  claim (race-free: bind can no longer succeed on the key), deletes
  unreferenced objects outside any transaction, and backs off failed
  deletes with attempt-based retry. Crash windows converge for free.
- The settle delay is a fixed constant carrying NO correctness weight;
  invariant tests pin it at >=10x every pipeline budget. Metrics cover
  deletes, referenced clears, delete failures, and ledger backlog.

Removed: MediaResolver.DiscardMedia, ErrMediaBindResultUnknown, the
post-commit verification, and both router discard branches.

Tests: intent-before-upload ordering; upload error leaves the row and
deletes nothing; bind-wins vs reconciler-wins on the same key; lost-ack
and rolled-back commit injections (intent cleared iff the attachment
landed); reconciler three-state settle; expired-lease reclaim; delete
failure backoff and retry; settle invariants.

* fix(channel): never build or sweep the media reconciler without storage

store is nil when S3 is unconfigured AND the local upload dir fails to
initialize, but the reconciler was constructed unconditionally and
main only gates the goroutine on the reconciler pointer — the first
unreferenced ledger row (rows can pre-exist from a boot where storage
worked) would nil-pointer panic a bare goroutine and take down the
process.

Construct the reconciler only when a storage backend exists, and guard
RunOnce defensively: with no deleter it skips the sweep without
claiming, so rows are not stranded in 'deleting' until lease expiry.
Test covers the pre-existing-row + missing-storage boot.

* refactor(channel): remove the dead pre-resolved MediaRefs ingress path

lark.InboundMessage.MediaRefs and the resolver's early-returns for
pre-populated refs were vestiges of the pre-detached synchronous design
— no producer fills them before the router anymore. Worse, the intent
ledger made the path actively misleading: refs arriving without ledger
rows would be silently skipped at bind (with a log blaming the
reconciler), contradicting the field's "already persisted" contract.

Delete the field, its channelMessageFromLark mapping, and both
early-returns; channel.InboundMessage.MediaRefs is now documented as
what it actually is — ResolveMedia's output channel, always empty on
ingress, attachable only through a claimed ledger intent.

* fix(channel): enforce workspace tenancy on every ledger query

The intent-ledger upsert's conflict branch guarded only on state, so a
cross-workspace storage_key collision could rewrite the row's
workspace/message/url ownership; release and delete keyed on
(storage_key, lease_token) alone. The derived key embeds the workspace
UUID so none of this is reachable today — but tenancy must be enforced
by the workspace column in every query, never derived from the key
string (MUL-3515 rule, restated in this PR's review).

The upsert now updates only within the same workspace (a cross-tenant
conflict updates nothing, returns no row, and the resolver skips the
upload — the fail-safe direction), and release/delete take
(workspace_id, storage_key, lease_token). Tests pin that a foreign
workspace can neither steal, release, nor delete a row.

* fix(migrations): build the ledger primary key via a concurrent index

storage_key TEXT PRIMARY KEY created its unique index implicitly at
CREATE TABLE, against the repo convention that every migration index —
including a new table's unique index — is built CONCURRENTLY in its
own single-statement migration (the exact three-step pattern
client_usage_daily shipped in 207-209). The table now declares
storage_key NOT NULL, 216 builds the unique index concurrently, and
217 attaches the primary key USING INDEX; the claim index moves to
218. ON CONFLICT (storage_key) still resolves against the constraint,
and the full down/up round-trip is verified.

* fix(channel): bound each reconciler object delete with its own timeout

DeleteObject ran on the worker-lifetime context and the SDK's default
HTTP client has no overall request timeout, so one black-holed
connection would wedge the sequential sweep loop — and with it every
later batch and the backlog gauge — forever; a single-replica
deployment has no other worker to reclaim the lease. Each delete now
gets a 30s timeout (well under the 2min lease), and a timed-out delete
takes the existing release/backoff path. Covered by a blocking-deleter
test with an injectable timeout.

* fix(channel): anchor the media deadline to the DB clock and bound queue waits by it

Two deadline gaps from review:

- The persisted marker was an application-clock timestamp compared
  against SQL now() everywhere it is read, so a skewed app node could
  shrink the fallback window and hand the agent a placeholder before
  the resolver's local budget ended. The append transaction now anchors
  a relative budget (MediaPendingSeconds) with now() + make_interval,
  writer and readers sharing one clock; the local resolve budget stays
  monotonic app-side. A DB test pins that the remaining budget measured
  by the DB clock equals the requested one.

- enqueueMedia's waits (per-session order, global slot) only watched
  shutdown, so in a burst an already-expired job kept its goroutine and
  payload until it reached the front. Both waits now also watch the
  message's deadline; on expiry the job skips the resolver entirely and
  runs only the empty finalize (marker clear + promotion), which also
  unblocks the session's later messages. Covered by a queued-expiry
  test that finalizes while the only slot is deterministically held.

* fix(channel): start the local media budget before the append transaction

The DB anchors the durable fallback at insert-time now(), but the
local monotonic budget started only after AppendMessage returned — so
the resolver outlived the fallback by the append/commit latency, a
window where the deferred task is already claimable while the resolver
still runs and the agent reads a placeholder that binds moments later.
Capture the local deadline before calling AppendMessage, restoring the
ordering local-gives-up <= durable-fallback-fires. A slow-append test
pins that the resolver's context deadline is measured from the
pre-append instant.

* fix(channel): heartbeat the reconciler lease per row

One claim covers up to 50 rows under a single 2-minute lease, but the
batch is processed sequentially and each delete may run its full 30s
timeout — a few stalled deletes could outlive the lease mid-batch,
letting another replica reclaim the tail: duplicate concurrent
deletes, inflated attempt/backoff on rows whose owner was alive, and
skewed metrics.

The lease is now renewed before EACH row's settle work, so it only
ever needs to cover one row's worst case (invariant-tested: lease >=
2x the per-delete timeout). A renewal that matches no row means
another worker reclaimed it after a genuine expiry — the row is
skipped, leaving the new owner's state untouched. Test simulates a
mid-batch reclaim and pins the skip.

* fix(channel): dedup post media resources and make local writes atomic

A rich post may reference the same image_key/file_key in several spans.
The object key derives from (message, type, key), so duplicates uploaded
to the SAME key twice: LocalStorage.UploadStream truncated the
destination up front and removed it outright on a copy error, so a
second failing attempt destroyed the object the first success had
produced — leaving an attachment row pointing at nothing. A second
succeeding attempt instead produced two attachment rows for one object.

Collapse duplicate spans by (fetch type, platform key) before the
upload loop, and write local uploads through a temp file renamed into
place so a failed write can only discard its own temp file. Tests cover
a duplicated span uploading once and a failed re-upload leaving the
previous object intact.

* fix(channel): fence late-materializing PUTs with a tombstone schedule

A DELETE cannot be ordered against a PUT the client already abandoned:
the store may materialize the object after the delete completes. The
reconciler cleared the ledger row right after deleting, so such an
object had no row and nothing to reclaim it — which made the settle
delay the de-facto correctness barrier for the PUT/DELETE race, exactly
what the design says it must not be.

The row is now kept as a tombstone ('tombstoned' state, migration 226's
CHECK) and re-deleted on a widening schedule (15m, 1h, 6h, 24h, the
pass index carried in last_error), so a late materialization is
reclaimed by a later pass; only after the schedule is exhausted is the
row dropped. Claim, heartbeat, lease, and tenancy predicates are
unchanged — a tombstone is claimed exactly like any other due row. A
separate gauge reports tombstones so they cannot be mistaken for a
backlog of objects awaiting reclaim, and the header comment now states
precisely what state fences (bind/commit) versus what the schedule
fences (late PUTs).

Tests: the reviewer's interleaving — DELETE completes, the abandoned PUT
materializes right after, and the object is gone by the end of the
schedule — plus a full schedule walk asserting the object is counted
once and the row clears at the end.

* fix(channel): tombstones must re-delete, not re-ask the reference question

A tombstone revisit ran the same reference check as a first settle, so
an attachment carrying the same URL — a re-ingested copy of the object —
sent the row down the "referenced, keep it" branch: the object was kept
and the row cleared, abandoning the re-delete schedule that fences the
ORIGINAL object against an abandoned PUT. A tombstone has already been
judged unreferenced and deleted; it exists only to re-delete whatever
materializes later, so it now goes straight to the delete + schedule
tail (extracted as settleDeletedObject, shared with the first settle).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(channel): keep the tombstone schedule position in its own column

The re-delete pass index was encoded into last_error, which the failure
path also writes: one failed re-delete erased the position and restarted
the walk. A store failing intermittently could therefore keep a tombstone
alive indefinitely — every recovery would resume at pass 1 and the row
would never reach the end of the schedule to be dropped.

tombstone_pass is now its own column (the table is introduced in this PR,
so migration 226 carries it), advanced only by a successful delete, and
the tombstone write clears the now-stale last_error. Test walks the
schedule across a failed re-delete and asserts it resumes rather than
restarts, and that the row still terminates.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(lark): derive media object keys per chat message

The object key was derived from the platform message alone, so a second
ingest of the same Feishu message reused the first ingest's ledger row.
That row can be a tombstone (up to ~31h while the re-delete schedule
runs), and the intent upsert refuses anything that has left 'pending', so
the second ingest skipped the upload and silently produced a placeholder
with no attachment. A re-ingest is reachable: the inbound dedup claim is
reclaimable once 60s stale and the dedup row is only vacuumed after 24h.

Keying on the chat message the object will attach to keeps the two
ingests independent, and nothing leaks: each one's objects are covered by
its own ledger row.

* refactor(storage): route both local upload paths through one atomic write

UploadStream wrote through a temp file and renamed into place, but the
buffered Upload path still truncated the destination up front — the
destructive shape the stream path exists to avoid, one caller away from
coming back. Both now share writeAtomic, which also restores the 0644 the
direct write used (CreateTemp makes files 0600).

* fix(storage): keep the local upload chmod best-effort

The rename-into-place rewrite made a failed chmod fail the whole upload.
CreateTemp's 0600 has to be widened to the 0644 the direct write used, but
an upload dir on a mount that ignores chmod (SMB/NFS/FUSE) accepted the
old direct write fine — turning those deployments' uploads into hard
errors would be a regression for a cosmetic property. Log and continue.

Tests pin 0644 on both upload paths, and that a failed buffered upload
leaves no temp litter and no damage to a previous object.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(channel): never re-delete an object an attachment references

The tombstone pass skipped the reference check and deleted unconditionally,
so a durable attachment carrying that URL lost the only object it can read
— the dangling attachment the intent ledger exists to prevent, and the
opposite of the posture every other path here takes ("a reclaimable orphan
beats a broken attachment").

The check now runs on every pass. A positive result on a tombstone is
unreachable by design — keys are per (chat message, resource) and a bind
cannot attach a key that has left 'pending' — so reaching it means an
invariant broke: keep the object, clear the row, log it, and count it on
a dedicated reconciler_tombstone_referenced_total counter. The test's
contract is flipped to assert the referenced object survives.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(storage): make the local staging file reclaimable after a crash

os.CreateTemp's random suffix meant a crash between the staging write and
the rename left a file nothing could name: the ledger records only the
final storage key, and DeleteObject removed only the object and its
sidecar. Each leftover can approach the 100 MiB resource cap and they
accumulate without bound.

The staging path is now derived from the object key, so DeleteObject
removes it alongside the object — which makes the media reconciler reclaim
it too, since the intent row is written before the upload. Opening it 0644
directly also drops the chmod the previous commit had to make best-effort.
Both read paths refuse the staging name (keys come from the request URL,
and a half-written body should not be readable); a user-supplied ".tmp"
extension is unaffected, since object keys are generated and never
dot-prefixed.

* chore(channel): renumber the media migrations after merging main

main took 224 (agent_task_session_rollout_missing), so the ledger group
moves to 225-230 and the cross-references inside the table migration follow.
main's CompleteTask also grew a sessionRolloutMissing parameter; the three
call sites this PR added to chat_input_ownership_test.go pass false.

Verified the way the numbering is meant to be verified: full migration set
applied from scratch on the merged tree, and the whole server suite run
against that database.

* fix(channel): let Postgres compute every reconciler deadline

The reconciler built settle cutoffs, lease expiry, backoff and re-delete
times from the process clock and compared them against the database's
now(). A replica whose clock had drifted would therefore settle rows whose
upload was still in flight (the object is deleted and the bind then refuses
to attach — media silently lost), hand out leases that are born expired
(rows churn between workers, attempt/backoff inflate), or compress the
tombstone schedule that fences a late-materializing PUT.

The four settle queries now take durations and derive their timestamps from
now(), so every replica reads one clock. The parameter types are the guard:
an app-side timestamp can no longer be passed. Test asserts the persisted
lease, backoff and re-delete deadlines all track the database's now().

The generated code also picks up main's new agent_task_queue column in the
two RETURNING task.* queries this PR adds.

* chore(lark): drop unrelated gofmt-only churn from this PR

Six files carried whitespace/comment-reformatting with no functional
change, unrelated to the inbound media pipeline. Reverting them to the
base revision keeps the diff focused on the feature (75 -> 69 files):

  server/internal/service/empty_claim_cache.go
  server/internal/integrations/lark/markdown_detect.go
  server/internal/integrations/lark/ws_chunk_assembler.go
  server/internal/integrations/lark/ws_chunk_assembler_test.go
  server/internal/integrations/lark/ws_frame_test.go
  server/internal/integrations/lark/registration_test.go

Verified: `git diff -w` against these files was already empty, so no
behavior is affected. go vet clean; tests covering these files pass.

e30776dd9b feat(agent): add Claude Opus 5 to the Claude runtime catalog (MUL-5282) (#5910)
Opus 5 is the current flagship in Claude Code's bundled catalog (verified
against claude-code 2.1.219: id `claude-opus-5`, display name "Opus 5",
pricing tier_5_25, capabilities include xhigh_effort/max_effort). Without a
catalog entry the model picker never offered it, and — more damaging —
ModelKnownIncompatibleWithProvider treats any unlisted `claude-*` id as a
known mismatch, so an agent manually pinned to `claude-opus-5` had the value
erased on save.

- Add `claude-opus-5` to claudeStaticModels(). Sonnet 4.6 stays the sole
  badged default; Opus remains a deliberate opt-in.
- Allow the full low/medium/high/xhigh/max effort range in
  claudeModelEffortAllow, matching the rest of the Opus family.
- Price it on the standard 5/25 Opus tier in both the server table and the
  frontend estimator, so Opus 5 usage lands in cost totals instead of the
  unmapped-model diagnostic. The existing `[1m]` and `<provider>/` tolerances
  cover the other spellings runtimes report.

Verified: go test ./pkg/agent/... ./internal/metrics/..., vitest
runtimes/utils.test.ts, tsc --noEmit on packages/views.

ffa8e16369 MUL-5228 fix(usage): bill Grok at xAI's reported cost, fix $0 resumed sessions (#5841)
* fix(agent): attribute Grok usage from the turn's own model id

A resumed Grok session with no configured model recorded its entire spend
under the model id "unknown", which matches no pricing row — so the task
reported $0 cost instead of its real spend.

grok.go only learned the model from the session handshake, and ACP's
`session/load` carries no model id (only `session/new` does). When neither
the agent nor MULTICA_GROK_MODEL pins a model, `daemon.go` legitimately
passes an empty model, leaving nothing to attribute the usage to.

Every Grok turn stamps `result._meta.modelId` with what it actually billed
against. Parse it in the shared ACP result parser and use it as the fallback
in grok.go. Other ACP backends are untouched — they keep whatever the
handshake gave them.

* fix(metrics): price the Grok catalog in server-side cost metrics

server/internal/metrics/pricing.go carried no Grok rows at all, so
RecordLLMUsage took the unpriced branch for every Grok turn: llm_cost_usd
reported zero Grok spend while the tokens accumulated in
llm_unpriced_tokens. Internal cost monitoring simply could not see Grok.

Add the six SKUs xAI publishes rates for, mirroring the frontend table in
packages/views/runtimes/utils.ts. Aliases are anchored exact matches like
the gpt-5.6 rows, so `grok-composer-*` (in the catalog, absent from the
price sheet) stays unmapped instead of inheriting a guessed rate.

Short-context tier on purpose: xAI bills a request at 2x once its prompt
reaches 200K tokens, but a usage record aggregates every model call in a
turn and cannot say which tier an individual request hit.

A regression test re-derives the cost of a real grok 0.2.106 turn from the
table and checks it against the costUsdTicks xAI returned for that turn.

* docs(changelog): scope the Grok cost claim to what was actually fixed

The v0.4.9 entry promised "accurate cost" in all four languages, but the
fix corrected catalog pricing and cached-input double-counting — it did not
implement xAI's 2x long-context tier, so a turn whose requests reach 200K
prompt tokens still under-reports by up to 50%. Say what was fixed instead.

Also correct two stale claims in the pricing comment: the daemon tags usage
rows with the runtime provider `grok`, not `xai` (the bare `grok-*` keys are
what make them resolve), and record why thresholding the long-context tier
on an aggregated row would be worse than not pricing it at all.

* feat(usage): carry the provider's own cost through to the usage record

Cost has always been derived client-side as tokens x a static rate, which
cannot express request-level pricing rules. xAI bills a Grok request at 2x
once its prompt reaches 200K tokens, and a task_usage row aggregates every
model call in a turn — so the stored token counts genuinely cannot say which
tier any individual request hit. Thresholding on the aggregate would be worse
than the status quo: it turns a bounded 50% under-estimate into an unbounded
over-estimate for turns made of many short requests.

Grok already reports what it charged, per turn, in `_meta.usage.costUsdTicks`.
Parse it, carry it through agent -> daemon -> API, and store it on task_usage
as a nullable BIGINT of 1e-10 USD ticks (integer, so sub-cent turns stay exact
end to end). NULL means the provider reported no cost — every pre-existing row
and every provider that doesn't return one. No backfill: there is no
authoritative figure to recover for those, and inventing one is the guess this
removes.

A single hourly bucket can mix rows that carry a cost with rows that don't, so
task_usage_hourly gains both halves: `cost_usd_ticks` sums the authoritative
side, and `uncosted_*_tokens` carry exactly the tokens that still need a
rate-table estimate. Consumers report authoritative + estimate(uncosted),
which degrades to today's behaviour when nothing in the bucket is
authoritative. The existing token columns keep covering every row, so token
displays are untouched. The new columns are additive with defaults, so the
unique key, the dirty-queue shape, and migration 102's triggers are unaffected.

* feat(usage): prefer the provider's own cost over the rate table

With the authoritative figure now stored, both cost consumers use it: the
usage dashboard (estimateCost / estimateCostBreakdown) and the server-side
llm_cost_usd metric. Each reports `authoritative + estimate(uncosted tokens)`,
so a row or bucket that mixes priced and unpriced sources stays whole.

The static rate tables remain, but for Grok they are now a fallback — they
still price usage recorded by a daemon too old to report cost, and every
provider that reports none. Custom pricing overrides likewise apply only to
the estimated half: they are a user's guess at a rate, and the authoritative
half is not a guess. A model with no rate-table row but a provider-reported
cost now also drops out of the "unmapped models" banner, since asking the user
to supply a rate for it would invite overriding a real bill.

llm_cost_usd is labelled by token_type and the provider reports one number per
turn, so the charge is distributed across the buckets in the rate table's own
proportions. Only the total is authoritative; the split stays an estimate,
which is why this scales the existing buckets rather than inventing a label.
estimateCostBreakdown does the same, keeping the stacked chart summing to the
headline figure instead of silently under-drawing every Grok row.

* docs(changelog): say Grok cost now follows xAI's actual charge

The earlier wording scoped the claim down to catalog pricing and cached input
because the long-context tier was still unhandled. It is handled now — the
cost comes from what xAI charged for the turn — so the entry can say so.

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

* fix(usage): keep the provider's cost when the model has no rate row

Both cost consumers bailed out before reading the authoritative figure when
the rate table had no row for the model. A `grok-composer-*` turn — in the
Grok Build catalog, absent from xAI's price sheet — was therefore reported as
$0 spend even though xAI told us exactly what it charged.

Worse on the client: estimateCost returned the real cost while
estimateCostBreakdown returned zeros, so the headline and the stacked chart
disagreed on precisely the rows whose cost is exact — and the unmapped-models
banner was (correctly) hidden, so nothing explained the discrepancy.

Handle the charge before the rate lookup in both places. Without rates there
is nothing to split a total by, so it lands whole in the `input` bucket, the
same fallback distributeAuthoritativeCost already uses when it has no shape to
scale. Tokens with no rate keep going to llm_unpriced_tokens: "unpriced"
describes the rate table, not the money.

* perf(usage): drop the historical rewrite from the cost-split migration

Migration 213 rewrote every existing task_usage_hourly row to seed the
uncosted counters. That is a full-table UPDATE inside a schema migration —
lock time, WAL and bloat all scaling with table size — for rows this issue
explicitly does not care about.

Deleting the UPDATE alone would have zeroed historical cost: with
`NOT NULL DEFAULT 0`, an untouched row asserts "nothing here needs
estimating", so every pre-split bucket would report $0 until the rollup
happened to touch it. Make the uncosted columns nullable with no default
instead. NULL means "never recomputed since the split existed", readers
COALESCE it to the row's own token total ("estimate all of it"), and the
pre-split behaviour is preserved exactly — with nothing to seed, so no
rewrite. A bare ADD COLUMN is metadata-only, so this is now fast DDL.

Rows heal into the split naturally as the rollup recomputes their buckets.

Verified on a fresh database: a legacy-shaped row reads back as its full
tokens to estimate, and a group mixing legacy and post-split buckets sums to
the authoritative cost plus both rows' estimable tokens.

a61a8ecfed feat(onboarding): merge About-you step, collect source after agents deliver value (#5786)
Flow drops from five steps to three: role + use_case merge into a
single About-you screen (one Skip covers both; Continue stamps skip
markers on whichever group was left unanswered), and the source
question leaves onboarding entirely.

Source is now collected only by the workspace source-backfill prompt,
which additionally waits until agents/squads have completed at least
SOURCE_BACKFILL_MIN_AGENT_DONE_ISSUES (3) issues in the workspace —
attribution is asked after Multica has visibly delivered value, not
before. The count rides a limit:1 issues query keyed under
issueKeys.all so realtime invalidations keep it fresh, enabled only
for users who still owe an answer.

Server: questionnaire complete() narrows to role + use_case so the
funnel step doesn't stall on the now-deferred source; a new
metrics-only onboarding_source_submitted event (+ Prometheus counter)
tracks the backfill prompt's answer/decline transition once per user.

1507997272 fix(agent): stop agents shipping local-path links, make Desktop 404 recoverable (MUL-4899) (#5557)
Agents were writing runtime-local paths into deliverables as clickable
links (`[screenshot](/Users/agent/work/shot.png)`). Two root causes, both
fixed here.

A. The brief never stated the delivery contract. Add an always-on delivery
invariant (outside writeOutput's kind switch, so no task kind can inherit
none) plus a per-surface file-delivery line for each of the five surfaces.
Chat splits into two: `attachment upload` works only on web/mobile chat,
never on an IM channel, so ChatChannelType is now threaded into
TaskContextForEnv.

The claim path only ever looked up Slack bindings, so a Feishu session
reported as a web chat and got upload guidance for a channel that cannot
carry attachments. Probe every channel type. The chat policy is two
independent layers and stays that way: delivery keys off "is there a
channel at all"; the `chat history` / `chat thread` commands stay
Slack-only because both endpoints are hardwired to h.SlackHistory and
there is no Feishu reader — ChatInThread only selects between those two
commands, so it stays Slack-only too.

Add a CLI hard-fail lint on `issue comment add` / `issue create` /
`issue update` as the enforcement backstop. Scoped narrowly, since a false
positive blocks a real deliverable: agent task context only (a human's PAT
run is untouched), real CommonMark link/image/autolink destinations only
via goldmark (a path in a code span or fence — how an agent quotes a path
it is discussing — is structurally invisible), and three high-confidence
signals only (`file://`, inside the workdir, or an existing local file).
A bare `/foo` is a valid origin-relative URI and is deliberately allowed.
`issue update` has no --attachment flag, so its hint redirects to
`comment add` rather than naming an argument it rejects.

B. Desktop presented the resulting router 404 as an unknown crash. 8 of 18
desktop_route_error reports were users clicking such a link and being told
the app broke and to file a bug. Split the 404 into a first-class Not Found
view: no crash framing, no Report error. Its recovery entry comes from the
tab store's active workspace, never from the failed pathname — deriving a
slug from `/Users/me/shot.png` yields "Users" and a button to `/Users/issues`,
a second 404.

Also add a will-navigate trusted-origin guard via the shared loadRenderer
(main + issue windows). This is origin hardening only, NOT the mechanism for
in-app links: client-side routing never fires will-navigate, so app paths
never reach it. Issue windows need no 404 work — their router only accepts
paths validated by parseIssueWindowPath and they do not listen for
multica:navigate, so a bad path cannot reach them.

Server-side completion observation is metric/log only and never blocks: it
is lexical (`file://` + task work_dir prefix) because the server cannot stat
the daemon's filesystem, and the metric label is a closed enum so no path or
reply text reaches Prometheus.

Verified: pnpm typecheck/lint/test (3582 tests), go vet, full Go suite
including new claim-path integration tests. cmd/multica was verified outside
the daemon workdir — inside one, 93 of its tests fail identically on
origin/main because the suite walks up and finds the runtime's own task marker.

06d79c1750 feat(agent): add Grok Build CLI as an ACP runtime (#5285)
Add xAI Grok Build (`grok`) as a first-class Multica runtime over ACP
(`grok --no-auto-update agent --always-approve stdio`), reusing
hermesClient like traecli and kimi. Includes daemon discovery,
protocol_family migration 174, model discovery, MCP passthrough,
thinking effort, frontend branding, and product docs.

Follows xAI's documented headless ACP flow: after `initialize`, read the
advertised `authMethods` and send `authenticate` (preferring xai.api_key
when XAI_API_KEY is set, else the cached login token) before any session
operation — a real, logged-in CLI rejects session/new and session/load
without it. Model discovery performs the same handshake so it returns the
live catalog instead of the static fallback.

`--no-auto-update` is passed as a global flag (and kept daemon-owned in
the blocked custom-arg set) so a background update check can't stall an
unattended ACP task. Thinking effort uses the current `--effort` flag,
and the minimum grok version is 0.2.89 (ACP + authenticate + session/load
+ session/set_model + MCP + --effort).

Closes #2895

8e0fbecab5 fix(models): codex empty-model effort validation + exact 5.6 aliases (MUL-4347) (#5196)
Follow-up to #5188 addressing the second-round review.

- ValidateThinkingLevel now fails an empty codex model closed instead of
  borrowing the flagged Default (gpt-5.6-sol). An empty model follows
  config.toml, which can resolve to any installed model; Sol alone advertises
  `ultra`, so the old borrow green-lit levels Luna / gpt-5.5 don't support and
  Codex doesn't reject. Checked before ListModels so a discovery error can't
  fail it open. Frontend pickModelEntry mirrors this (no per-model effort
  preview for an empty codex model); the persisted-orphan clear path stays.
- parseCodexDebugModels drops efforts without a known label so the picker
  never advertises a level the Create/Update enum gate would 400 on save; the
  contract test now drives the real parser with an unknown effort instead of
  comparing two hand-written maps.
- gpt-5.6 price aliases anchor to a literal dot (not the [.-] class), so
  dashed variants like gpt-5-6-luna surface as unmapped on both backend and
  frontend rather than silently borrowing a tier.

  surface as unmapped instead of borrowing a tier.
- Add Codex 0.144.1 max/ultra effort levels to the label map and server
  enum so the daemon-advertised catalog matches what the API can persist;
  add a catalog->API contract test.

3cb5dc3ad6 chore(analytics): retire redundant PostHog tracking (MUL-4127) (#4996)
* chore(analytics): retire redundant PostHog tracking (MUL-4127)

PostHog had become a chaotic, largely-unused second copy of data we already
query from the DB and Grafana. Remove the redundant instrumentation.

Server: every product event (signup, workspace_created, issue_created,
issue_executed, chat_message_sent, team_invite_*, onboarding_*, agent_created,
cloud_waitlist_joined, feedback_submitted, contact_sales_submitted,
squad_created, autopilot_created) is now in metricsOnlyEvents, so
metrics.RecordEvent still increments the Prometheus/Grafana counter but no longer
ships to PostHog. DB rows remain the source of truth. Runtime/autopilot/
agent_task lifecycle were already Prometheus-only.

Frontend: delete the PostHog-only funnel instrumentation — $pageview (+ web and
desktop trackers), download_intent_expressed/page_viewed/initiated, the
onboarding_started mirror, onboarding_runtime_path_selected/detected,
feedback_opened, and source_backfill_*. The source-backfill modal itself stays
(it PATCHes the questionnaire to the DB).

Kept on PostHog (frontend only): $exception autocapture and the
client_crash / client_unresponsive stability telemetry (no DB equivalent), plus
$identify/$set. captureSignupSource (attribution cookie) stays — it still feeds
the signup_source Prometheus label.

  Prometheus-only (multica_issue_executed_total) + issue.first_executed_at, in
  both the event contract and the Reconciliation section.
- docs/analytics.md: the signup $set_once person properties (email, signup_source)
  are no longer emitted — signup is Prometheus-only; only the bucketed
  signup_source survives as the multica_signup_total label.
- server/internal/metrics/business_events.go: RecordEvent doc comment no longer
  claims it ships product events to PostHog / "PostHog is reserved for
  user/product-behaviour events" — every server event is now metrics-only.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* 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.

* 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.
