* ⏳ fix: Anchor Resumed Elapsed Time at the Generation's Real Start

A reload emptied the Recoil anchor, so the indicator fell back to its
mount time and visibly reset to 0s over a run that had been generating
for much longer. The stream status the resume path already reads carries
the server-recorded generation start; the fill now prefers it, so a
reattached run reports real elapsed time. The fill remains fill-only:
a same-session reattach keeps its original ask baseline, and the
indicator's existing clamp absorbs any client/server clock skew.

* 🕰️ fix: Rebuild the Resumed Baseline From the Server-Computed Age

Codex round 1: anchoring at the server's raw createdAt compares two
clocks — a client behind the server froze the resumed reading at 0s for
the skew, one ahead inflated it. The status route now also reports the
generation's age computed on its own clock, and the client rebuilds a
clock-local anchor as Date.now() minus that age, so each machine only
ever compares to itself. Raw createdAt stays as the fallback for an
older server mid-rolling-deploy.

* 📥 fix: Compute Elapsed Age in TypeScript, Anchor It at Status Receipt

Codex round 2: the elapsed computation moves into packages/api as
getGenerationElapsedMs — the route now just delegates, keeping the
response contract type-checked and the /api surface a thin wrapper —
and the client subtracts the age from the moment the status response
arrived (dataUpdatedAt) rather than from apply time, so a slow history
fetch between receipt and apply can no longer shrink the reading.
Declined with rationale: a shared clock source across replicas — the
residual is inter-replica NTP drift, milliseconds against the
minutes-scale client skew this PR eliminates, and the helper gives any
future shared-clock upgrade a single home.

⚡ perf: Cut Serial Round Trips and a 100ms Admission Stall from Chat Turns (#15138)
* ⚡ perf: Stop Awaiting the Conversation Access Marker Write

Without Redis the CONVO_ACCESS violations namespace is backed by keyv-file,
whose debounced write resolves after ~100ms. validateConvoAccess awaited
that write before calling next(), so the first message to any existing
conversation waited ~100ms before the request was even admitted — once
per conversation per ten-minute window, on every default deployment.

The marker only short-circuits the next check, so the write no longer
gates the request. The same read now stashes the full document on
req.resolvedConversation (null when absent) for downstream consumers.

First-turn ack on an existing conversation: 109ms -> 5ms.

* ⚡ perf: Read the Conversation Once per Chat Turn

A chat turn read the same conversation document four times: the access
check (two fields), the subagent thread guard (full document), agent
initialization (the files field), and the first save. The access check
now reads the full document and leaves it on req.resolvedConversation,
the guard accepts that pre-resolved document instead of re-reading, and
initializeAgent takes the conversation's file refs from it rather than
issuing a separate findOne.

Two serial round trips removed from every turn; the same document still
serves the first save as before.

* ⚡ perf: Remove Duplicate JWT Authentication on Agents Routes

routes/agents/index.js applies requireJwtAuth and then mounts the v1
router at '/', which applied requireJwtAuth again. Every request through
the agents router — chat turns included — ran the passport strategy
twice: two signature checks and two user document reads. The v1 router
is mounted nowhere else; its separately exported avatar router carries
its own auth in files/index.js.

* ⚡ perf: Skip the History Read for Root-Parent Turns and Walk the Tree in O(n)

loadHistory fetched every message in the conversation and then walked the
parent chain from the request's head. For a new conversation — or a new
branch from the root of an existing one — the head is the root sentinel,
which no message carries as its id, so the walk was empty by construction
and the fetch was wasted. It now returns early.

getMessagesForConversation found each ancestor with Array.find inside the
walk, O(n^2) on a linear conversation (~5ms at 1000 messages). A Map by
messageId makes it O(n); first-match semantics are preserved.

⏱️ feat: Run Scheduled Chats Through Durable Agent Triggers (#14939)
* feat: Scheduled Chats — agent-centric scheduled runs creating real conversations

Squash of the full review-hardened branch (PR 14540, supersedes 14373) onto
latest dev, preserving the exact verified tree. History prior to this commit
lived on the pre-squash branch; every invariant below survived 25 Codex review
rounds plus two external audit rounds (R26) with regression tests that fail
without their fixes.

Feature:
- Schedules CRUD + side-panel UI (cadence dialog, run cards, Run Now), roles/
  permissions (SCHEDULES:USE), interface.schedules availability, per-user limits
  and capacity slots, timezone-aware cadence with DST-conservative floors and
  misfire grace.
- Engine: single-process claim/fire loop with leases, loopback POST dispatch
  (signed schedule-fire JWT claims, per-occurrence idempotency key inside the
  route's clientRequestId charset), overlap/balance/capacity/duplicate skip
  policies with auto-disable streaks (too_many_failures, insufficient_balance),
  reconciliation from retained terminal-job evidence, erasure sweep.
- Scheduled runs create real conversations through the resumable agents chat
  path: HITL pauses surface on the card (requires_action), resumes re-apply the
  fire boundary's admission policy (revision fence, enabled, global kill switch,
  SCHEDULES:USE, availability) before continuing a billed generation.

Correctness invariants (the audit surface):
- Settlement discipline: every persistence-producing write happens-before a
  run's terminal outcome write; Stop/complete/pause race through single-winner
  terminal CAS claims (dev's TerminalJobClaim substrate) with retained,
  completedAt-less evidence for scheduled fires plus an owner-intended outcome
  stamp (scheduleOutcome) the reconciler prefers over re-derived success —
  round-tripped through the Redis hash mapper.
- Swallowed generation failures (client error content parts) classify to
  error/skipped_balance instead of success on both initial and resumed paths;
  stale stamps are refreshed evidence-first when persistence plus the Mongo
  outcome write both fail.
- Abort honesty: delivery judged by generation ownership and the CAS's actual
  from-status; republication escalates to the transport's acknowledged variant;
  the Stop route settles only genuinely paused runs.
- Account deletion: one-way barrier (deletionRequestedAt) with auth-cache
  tombstone-before-stamp, boundary rechecks across all auth strategies, quiesce
  of scheduled + interactive work with durable per-stream abort fences
  (positive-evidence acknowledgement only), owner-side finalization markers for
  post-terminal billed writes, deferred-deletion sweep (explicitly ensured
  partial index) that completes cascades autonomously. Remote OpenAI-compatible/
  Responses requests are documented as outside the quiesce and tracked in issue
  14594.
- Store compatibility: finalization markers optional on the legacy IJobStore
  contract with coherent degradation (registration fails -> synchronous title
  fallback; count reads 0).

* fix: fence terminal response persistence from deletion; retain stale-pause evidence

Two blockers from the third external review round.

Terminal persistence visible to account deletion:

- The finalization marker was registered only when post-terminal TITLE work was
  possible, but every persistence-owning terminal CAS opens the same window: the
  claim drops the job out of the active set BEFORE the response save (and the
  background user-message/convo saves), so a deletion quiesce landing there saw
  neither an active job nor a marker and could cascade while the admitted request
  could still recreate messages. Both controllers now register the marker before
  every persistence-owning claim — the fresh-turn path and the HITL resume — and
  release it only after their pending saves (and any post-terminal title) have
  landed, on success and failure paths alike. The TTL bounds a crash.
- settleAbortFence no longer clears a complete/error fence while
  `terminalPersistencePending` is set: terminal at the CAS is not settled while
  the owner is still persisting. The job facade now surfaces the flag.
- The marker trio is REQUIRED by the runtime store contract (assertJobStoreV2
  refuses a store without it at configure time, keeping the failure loud and
  deterministic) while remaining optional on the legacy public IJobStore type for
  source compatibility. The silent degrade path from the previous round is gone —
  it was not deletion-safe.

Stale-pause recovery retains scheduled evidence:

- Three crash/timeout recovery paths — ApprovalLifecycle.failStalePausePersistence
  and the InMemory/Redis stale-pause cleanups — unconditionally stamped
  `completedAt`, putting a scheduled fire's failed-pause error terminal on the
  short completed TTL. A Mongo outage longer than that TTL erased the evidence and
  the reconciler recovered the run as `interrupted` instead of `error`. All three
  now follow the controller-observed path from the previous round: scheduled jobs
  omit `completedAt` (retained-evidence TTL) and stamp the error outcome.

The PR description now explicitly narrows the deletion guarantee for the remote
OpenAI-compatible/Responses paths (tracked in issue 14594).

* fix: deletion-fence marker protocol — generation-scoped, atomic, fail-closed, all terminal paths

One consolidated pass over the finalization-marker mechanism, per the fourth
external review round. The invariant it establishes: NO persistence-owning
terminal CAS runs without a durable, generation-qualified marker covering the
window it opens, and every consumer treats a pending terminal as unsettled.

- Generation-scoped markers. Entries were keyed (userId, streamId), so a
  Stop-superseded generation finishing late could clear the marker its
  replacement registered on the same conversation. Marker fields are now
  qualified by the generation's createdAt; clears must present the same
  identity, and an unqualified legacy clear cannot drop a qualified entry.
- Atomic Redis registration. HSET-then-EXPIRE loses the fresh marker when the
  user's existing hash expires between the two commands (or the process dies
  there); registration is now a single Lua script carrying both.
- Fail closed everywhere. Registration failure (after one retry) now REFUSES
  the terminal CAS instead of proceeding uncovered: the completion claim throws
  into the error path, the error path skips completeJob and leaves the job
  ACTIVE — deletion-visible by itself, recovered by the stale-running reaper —
  and abortJob returns a new retryable `fence_unavailable` failure the Stop
  route answers with 503 and the deletion quiesce treats as an unacknowledged
  stop (fence kept). The previous round's log-and-proceed is gone.
- Every terminal path enrolled. abortJob now owns its window (register before
  the abort CAS, clear in its finally — the Stop route's checkpoint prune and
  partial save run inside beforePublish, between CAS and publication); the
  interactive and background generation-error paths register before their
  completeJob; the resume controller's error finalization registers before its
  completeJob. A lost or thrown claim releases the marker after pending saves
  flush instead of holding the user's deletion behind the TTL.
- Every pending terminal unsettled. settleAbortFence defers on
  terminalPersistencePending for ALL statuses — including `aborted`, whose
  route-side persistence the previous guard missed.

Also: a direct Redis regression for scheduled stale-pause retention (the P2
test gap), and the PR description no longer claims to carry every commit.

* fix: lease-token lifecycle fences — same-generation isolation, admission fence, undelivered-Stop retention, legacy abort enrollment

Fifth external review round; four P1s, handled as the requested consolidated
lifecycle-fence pass.

- Lease tokens. Marker fields were (streamId, createdAt), shared by every
  contender on the same generation — completion and Stop, or two racing Stops —
  so a losing contender's cleanup erased the winner's still-live marker. Every
  registrant now carries a unique lease token in the field and may only ever
  clear its own lease; unqualified legacy clears cannot touch qualified entries.

- Admission fence. Authentication can pass before the deletion barrier goes up,
  and the durable createJob is several async steps later — a deletion quiesce in
  that window saw neither an active job nor a marker and could cascade before
  the admitted request created its job. The controller now registers an
  admission lease and THEN rereads the deletion barrier: the ordering guarantees
  either this request observes the barrier (403, lease released, slot/claim
  cleanup) or the quiesce observes the lease and defers. Held until createJob is
  durable; released on every refusal and initialization-error path. Fail closed
  when the lease itself cannot be registered (503 retryable).

- Undelivered-Stop retention. abortJob released its lease in a finally even when
  delivery AND publication had provably failed — the job reads terminal
  (invisible to active-set scans), a user Stop writes no durable abort fence,
  and the remote owner keeps generating and will persist its abort-catch writes
  whenever the signal finally lands. The lease is now retained in exactly that
  case, and each resignal attempt heartbeats a fresh lease so the fence outlives
  the TTL for as long as delivery is still being driven. The abort-winning
  turn's own loser-side pending saves are additionally fenced in the controller
  catch (best-effort — those writes are already in flight).

- Legacy abort enrollment. abortMiddleware (assistants abort route fallback for
  non-assistants endpoints) awaited abortJob and then spent usage and saved the
  stopped response AFTER the abort's lease was released. Both writes now run
  inside `beforePublish`, between the abort CAS and publication, covered by the
  same lease as every other abort.

Barrier tests, each verified to fail without its fix: same-generation lease
isolation (store), racing two-Stop loser cleanup (manager, stale-read forced
CAS race), undelivered-Stop lease retention, resignal heartbeat, admission
refusal with lease-before-reread ordering plus release-on-durable-create, and
legacy-abort persistence inside beforePublish.

* fix: heartbeat-backed owner-lifecycle leases close the settlement handoff races

Sixth external review round: the remaining P1 interleavings were one structural
problem — lease handoffs that were not atomic — resolved as the requested
consolidated lifecycle-lease pass.

- Quiesce reads leases BEFORE the active-job scan. The admission-lease -> durable
  -job handoff is only atomic against a reader in the OPPOSITE order of the
  writer: writers hold the lease strictly until the job is active-set visible,
  so leases-first shows every interleaving either the lease or the job.
  Jobs-first allowed a request to create its job after the scan and release its
  lease before the count — hiding both, cascading, and letting the new
  generation persist into a deleted account.

- The abort acknowledgement is fenced by the owner-lifecycle lease. Redis ACKed
  the moment the owner's AbortController tripped; the stopping side released its
  lease on that ACK while the owner's asynchronous abort-catch persistence was
  still ahead. The transport now awaits a manager-installed pre-ACK hook that
  registers a DETERMINISTIC owner lease (exactly one owner exists per
  generation, and determinism is what lets the signal-time registrant and the
  owner's catch-side release agree across processes) before the acknowledgement
  is persisted or published; an owned same-replica abort bridges to the same
  lease before tripping its local controller. Both generation-owner catches
  (fresh turn, resume) release it once their writes land.

- A failed replacement handoff no longer orphans the predecessor. The atomic
  replacement removes it from active storage, and an unconfirmed handoff
  terminalizes the replacement too — leaving nothing a quiesce could discover
  while the predecessor's provider may still be generating. Its owner lease is
  now retained at the point the receipt fails delivery; the owner replica renews
  it through the pre-ACK fence when the signal finally lands.

- Leases HEARTBEAT while held. The five-minute store TTL only bounds a crashed
  holder; live persistence — a stalled save, a long deferred title — must never
  outlive its own fence. holdUserFinalization registers and renews every minute
  until released; the controllers' completion/error/admission leases all hold.
  The undelivered-Stop retention moved to a deterministic `stop` lease that
  every resignal attempt renews and the first successful one clears (no more
  opaque leases accumulating to TTL), and a THROWN abort transition releases the
  contender lease instead of leaking it.

- The user-document abort-fence mutations now invalidate the auth user-doc
  cache, matching every other user-doc write.

Barrier tests, each verified to fail without its fix: quiesce lease-scan
ordering (plus the observed-lease defer), pre-ACK fence ordering at the
transport, owned-abort owner-lease bridging, replacement-handoff predecessor
retention, held-lease heartbeat past the TTL, and failed-then-successful
resignal reaping the retained stop lease.

* fix: one manager-owned owner-lease span across every abort delivery path

Seventh external review round; four lifecycle-fence gaps, closed by making the
owner-lifecycle lease a single manager-owned, heartbeat-held span.

- Fail-closed acknowledgements. The pre-ACK hook registered a one-shot lease and
  the transport ACKed even when it failed; a same-replica owned abort likewise
  swallowed registration failure. The hook now acquires a HELD owner lease
  (heartbeat until the owner's catch releases it via releaseOwnerLease) and a
  rejection SUPPRESSES the acknowledgement — the stopping side stays retryable
  behind its retention lease, and every resignal re-drives the handler. The hook
  also stopped gating on `job.createdAt === generationId`: during a replacement
  handoff the store holds the replacement while the abort targets the
  predecessor, and that gate silently skipped exactly the generation being
  acknowledged (the store job is owner identity, never a generation gate). A
  local owned abort acquires the same held lease before tripping its provider;
  post-CAS the trip cannot be withheld, so acquisition failure downgrades
  delivery and the retention handoff keeps the user fenced.

- Committed-but-lost-reply disambiguation. A thrown abort transition released
  the contender lease as if nothing had happened, but a Lua CAS can commit and
  lose its reply — an aborted job invisible to active-set scans whose provider
  was never signalled, with no fence left. The throw path now re-reads the exact
  generation: only a job still live under the caller's identity proves no
  commit; committed or ambiguous outcomes hand the fence to the deterministic
  stop lease (kept on the contender lease if even that fails) before rethrowing.

- Replacement handoff covered end to end. A LOCAL replacement abort acquires the
  predecessor's held owner lease before the trip (failure reports the receipt
  undelivered, engaging retention). Failed-handoff retention is no longer a
  swallowed one-shot: it heartbeats with the durable acknowledgement proof as
  its renewal predicate — acquisition failures keep retrying for as long as the
  fence is needed, and the retainer stands down (without clearing the shared
  field) once the remote owner ACKs and thereby holds its own lease.

- A LOCAL resignal delivery hands off to the owner lease BEFORE clearing the
  retained stop lease, and keeps the stop lease when that handoff fails.

Barrier tests: hook rejection suppressing the ACK, commit-then-lost-reply
retention with its provably-uncommitted counterpart, local-resignal owner
handoff ordering, pre-ACK owner lease held past the store TTL until release
(and provably stopped after), and failed-handoff retention retrying on its
heartbeat — verified fail-before/pass-after by stashing the fixes.

* fix: repair schedule dialog interaction and rework its form

The agent picker was unusable: ControlCombobox portals its popover to the
body by default, which lands it outside the dialog's Radix focus trap. Clicks
passed through it, it could not be tabbed into, and the trap fighting Ariakit
for focus locked the page up on selection. The prop is documented for exactly
this case — pass `portal={false}` and give the dialog `overflow-visible`, as
ProjectButton already does. The time and day dropdowns defaulted the same way.

Alongside that:

- Extract the agent builder's instructions editor (special-variable menu plus
  expand-to-fullscreen) into a controlled `VariableEditor` and use it for the
  schedule prompt. Insertions now route through `onChange`, so react-hook-form
  sees them — the schedule PATCH is built from `dirtyFields`, and a `setValue`
  that skipped dirty tracking would have dropped an inserted variable silently.
- Replace the hand-rolled frequency buttons with the shared `Radio`. They marked
  the selection with `bg-surface-hover` on an outline button whose hover is the
  same token, so the selected option was indistinguishable from a hovered one;
  `Radio` is also a real radiogroup rather than four `aria-pressed` toggles.
- Wrap the fields in a real `<form>` and associate the footer button by id, so
  Enter submits. Group the frequency, day and time controls in fieldsets.
- Add placeholders for name and prompt, match the textarea fill to the other
  fields, and label the hourly case as minutes past the hour.
- Widen the dialog to `md:max-w-3xl` and pair name with agent so the form fits
  without scrolling on desktop.
- Move scheduled chats below skills and above prompts in the side nav.

The new dialog spec fails when the portal fix is reverted.

* test: cover scheduled and subagent deletion drains

* refactor: own the form-control appearance in the client primitives

Addresses the codex finding on ScheduleDialog: a feature-local `FIELD_CLASS`
restated the `Input` primitive's border, radius, height and background so it
could be pasted onto the schedule dropdowns, leaving those controls with no
connection to the primitive they were imitating.

Move that appearance into `packages/client/src/components/Field.ts` as the
single source `Input` and `Textarea` now compose, and give `Dropdown` and
`ControlCombobox` a `variant="field"` that applies it. The schedule dialog
passes the variant and carries no class strings of its own.

This also repairs a break the dev merge would otherwise have introduced: the
newer `Dropdown` splits `className` (wrapper) from `triggerClassName`, so the
old pasted classes would have landed on the wrapper and left the triggers
unstyled.

The semantic-token guard now watches the shared module and asserts each
primitive still composes it, which covers more than the two files it read
before.

* fix: keep an explicit schedules disable from becoming an opt-in

`use` is two things at once for a dual-purpose runtime interface field: a
permission bit, which DB overrides strip, and the runtime disable signal that
`getLimits` reads. Stripping it from `{ use: false, maxPerUser: 2 }` leaves an
object, and `getLimits` treats any object without `use: false` as enabled — so
an admin override written to stop scheduled billing for a role or user started
it instead.

Collapse an explicit disable to the boolean form before the strip, on both
paths that accept it: the `interface.schedules` field patch, which admitted the
object wholesale because bare runtime paths deliberately bypass the permission
gate, and the overrides merge, which reached the composite-field branch and
kept `maxPerUser`. Objects that only narrow limits are untouched, so a
principal can still be given a smaller cap.

Both regressions fail without the normalizer.

* fix(schedules): Wave A — null-balance CAS, atomic paused-card clear, clustered erasure sweep

Slice 1 (thread r3804518381): route the existing-null balance initialization
through a { user, tokenCredits: null } compare-and-set instead of a blind $set,
so a concurrent initializer/charge landing between the preflight read and the
write is never handed back its spent starting balance. On a CAS miss the
preflight re-reads the winner. The absent-record $setOnInsert path and the
credited-record refill-config sync are unchanged. Adds the initializeNullBalance
adapter (no upsert) and regression coverage for winner/miss/sync cases.

Slice 2 (thread r3804518388): updateScheduleById now drops a `requires_action`
lastRun projection atomically with the configRevision bump. Any pause present at
edit time was projected under the pre-edit revision and can never be replaced by
its own revision-fenced terminal outcome — a disabling edit would strand the
card on "Needs approval" forever. Implemented as classic-operator CAS branches
(DocumentDB rules out a conditional pipeline $unset), fenced on the card STILL
being the pause so a terminal outcome or newer occurrence that races in is
preserved. Terminal history survives untouched.

Slice 4 (thread r3803826204): expose initializeScheduleErasureSweep from the
schedule runtime facade and start it in every clustered (experimental) worker
after Mongo is up. It re-drives eraseScheduleIfDrained for soft-deleted rows so
a hidden prompt cannot outlive its drain when the delete/erase-on-settle
attempts miss. It arms nothing else and never infers owner death from a
process-local missing job (isTopologySafeToArm gates that).

* fix(schedules): Wave B.1 — reversible account-deletion schedule suspension

Thread r3804518383. Account-deletion quiesce marked every schedule `deleting`,
disabled it, and cleared nextRunAt destructively. When a later cascade step (or
the drain itself) failed, the controller cancelled the user-deletion fence —
restoring the user — but the schedules stayed `deleting` and were erased by the
sweep, silently losing all of a live user's scheduled prompts.

Replace the destructive marking with a REVERSIBLE, token-fenced suspension:

- suspendUserSchedulesForDeletion(userId, token) snapshots each schedule's prior
  enabled/nextRunAt under a per-attempt token, then fences firing (disable, clear
  nextRunAt, rotate claimToken). It never sets `deleting`, so a suspended row is
  not erasure-eligible. Snapshotting reads then bulkWrites (a classic update
  cannot copy field values under DocumentDB), fenced per row so an already-
  suspended/soft-deleted/edited row is left alone; idempotent per token.
- restoreUserSchedulesFromDeletion(userId, token) reverses it, re-enabling and
  re-arming only rows still carrying the exact attempt token and not independently
  deleted — so an owner-deleted or newer-attempt-suspended schedule is never
  resurrected.
- deleteUserController generates the attempt token, passes it to quiesce, and on
  any failure that cancels the user-deletion fence restores the suspended rows. A
  successful deletion hard-deletes them (and their snapshots) via the existing
  cascade and never restores.

Adds a `deletionSuspension` embedded field (excluded from the wire schedule),
data-method regression tests (suspend/restore/fence/idempotency/no-resurrect),
and controller tests (restore on drain-false and post-quiesce cascade failure,
no restore on success).

* fix(schedules): Wave B.2 — wire the interactive Stop persistence protocol

Thread r3804255932. The durable Stop primitives (requestRunAbort 'stop',
getScheduleRunAbortState, markRunAbortPersisted) already existed but production
only used requestRunAbort(..., 'deletion'). An interactive Stop flipped the job
to `aborted` and then persisted its partial message + checkpoint inside
`beforePublish`, without ever stamping the schedule Stop or acknowledging it —
so reconciliation, the generation owner, or a concurrent schedule/account
deletion could terminalize the run and release its capacity (and erase data)
mid-write.

Wire the request -> persist -> acknowledge -> settle barrier through the
schedule runtime (the route never touches raw Mongo):

- Expose beginScheduledStop / acknowledgeScheduledStopPersistence on the service.
- The abort route stamps the Stop BEFORE signalling abortJob (a serialized
  'in_progress' loser returns 409 STOP_IN_PROGRESS without a second abort),
  acknowledges only after beforePublish persistence succeeds, and on a
  persistence failure leaves the barrier unresolved so the run stays preserved
  (client retries; stale-owner timeout is the bounded recovery). A failed abort
  releases the stamp it placed so a replacement/retry is never blocked through
  its predecessor.
- recordScheduleOutcome (the owner settlement path) now waits, bounded, for the
  Stop acknowledgement before terminalizing; a resolved/non-stop/stale marker
  proceeds immediately. The paused Stop settles only after its own ack.

Adds service-layer barrier tests and route-level ordering/persistence-failure/
in-progress tests; the data-layer serialization is already covered.

* fix(schedules): Wave C.1 — reconcile durable trigger delivery with the reservation

Threads r3803826192 (manual limiter) and r3804255924 (PII/moderation), plus the
independently-found long-Retry-After race. fireSchedule reserves a `started` run
and a global capacity slot BEFORE the durable trigger delivery reaches the chat
route, where an interactive limiter (manual Run Now), PII, or moderation can
reject it before any generation job exists — dead-lettering the delivery while
the run sat `started` until the 30-minute orphan sweep mislabeled it interrupted.
And a valid delivery deferred by Retry-After (up to 24h) could be orphan-settled
and have its capacity released, then fire anyway.

Translate durable delivery state into the schedule outcome:

- Store the deterministic trigger deliveryKey on the ScheduleRun reservation
  (computed from the envelope BEFORE enqueue, so an ambiguous commit still has it).
- Add a getTriggerDelivery engine dep (wired to the merged trigger service's
  getDelivery) that reads the durable delivery by key.
- Schedule reconciliation, for a jobless `started` run: staging/pending/leased →
  admission is live, never orphan; dead → record `error` from the durable
  lastError and release capacity promptly (no 30-minute wait), through the
  ordinary outcome/auto-disable path; succeeded or no record → the existing
  legacy orphan policy (interrupted only past the cutoff); a delivery lookup
  failure defers rather than orphaning a possibly-live delivery. Limiter/PII/
  moderation middleware writes no schedule state.

Adds reconcile state-mapping tests (dead/pending/leased/staging/succeeded/none/
lookup-failure) and a fire test that the reservation's deliveryKey equals the
enqueued delivery's idempotency key.

* fix(stream): Wave C.2 — durable retry/ack for terminal host lifecycle actions

Thread r3804518375. Approval expiry won the `requires_action → aborted` CAS and
then invoked the host hook best-effort: `runApprovalExpiredHandler` swallowed a
failure, and because later sweeps enumerate only `requires_action` jobs, the now-
aborted job was never offered again. In the clustered entrypoint (no schedule
reconciler) the ScheduleRun stayed `requires_action` and its retained job
persisted indefinitely.

Make the host lifecycle work durable rather than schedule-specific:

- Add a generic `terminalHostActionPending` marker, set ATOMICALLY in the same
  terminal transition (ApprovalLifecycle.expireWithIdentity), only when a host
  adapter is installed.
- Retain and index such jobs: both stores keep them out of terminal reaping and
  expose getTerminalHostActionJobs(); Redis adds a set + extended (24h-bounded)
  TTL, in-memory a bounded 24h retention so a permanently-failing hook cannot leak.
- The manager clears the marker only after the adapter acknowledges success,
  fenced by generation identity (clearTerminalHostAction), so a replacement
  generation can neither clear nor execute its predecessor's action.
- cleanup()/expireStaleApprovals() enumerates unacknowledged terminal host actions
  across restarts and replicas and retries the idempotent hook; the relay only
  re-invokes while the marker is unacknowledged, so a successful ack prevents
  duplicate work. Store-won expiry marks it too, so a loser-replica relay still
  crosses the hook.
- Terminal SSE notification continues regardless of host-hook outcome.

Covers in-memory behavior (retry after failure, restart/other-replica retry, ack
prevents duplicates, identity fence, terminal notification on failure, no marker
accumulation for non-scheduled jobs) and updates the Redis cluster-membership
contract test for the new index.

* fix(schedules): repair the deletion CLI and order restore before the fence release

Addresses three findings from the fresh Codex review.

P1 — config/delete-user.js called methods.disableUserSchedulesForDeletion, which
Wave B removed in favor of suspendUserSchedulesForDeletion. The file is
@ts-nocheck and its spec mocked the removed name, so neither typecheck nor tests
caught it; the real CLI would throw a TypeError before deleting anything and then
only unwind the fence. The CLI now uses the tokenized protocol: it mints a
suspension token, suspends with it, and restores that exact attempt's rows in its
finally block when the deletion does not commit. Its spec mocks the real methods,
so the breakage can no longer hide.

P2 — both the HTTP controller and the CLI released the user-deletion fence BEFORE
restoring schedules. That fence is what refuses new schedule writes/claims, so the
gap let an owner PATCH edit a still-suspended row and have its enabled/next-run
state overwritten by the older snapshot, and let a second deletion attempt
re-suspend under a new token — making the first restore a no-op and stranding the
disabled snapshot permanently. Restore now runs first, while writes are still
fenced.

Hardening for the same defect class across a crash: suspendUserSchedulesForDeletion
now ADOPTS an existing suspension's snapshot when re-suspending a row abandoned by
an earlier attempt, instead of re-capturing the row's current (already-suspended)
state. Without this, an attempt that died before restoring would have its
successor snapshot "disabled, no next run" and permanently strand the schedule.

Tests: CLI restore-before-fence ordering and no-restore-on-success; the same
ordering assertion on both controller post-quiesce failure paths; a data-method
regression that a second attempt adopts the abandoned snapshot and restores the
original enabled/next-run state.

* fix(schedules): converge dead deliveries in topology-safe maintenance

Codex finding: the `dead` delivery mapping added in Wave C.1 lives only inside
startScheduleEngine's reconciler, but the clustered entrypoint arms no engine — it
runs erasure-only maintenance. A delivery queued before a restart into clustered
mode and then rejected before generation creation (interactive limiter, PII,
moderation) dead-letters while its ScheduleRun stays `started`, holding a global
capacity slot indefinitely for an ordinary non-deleting schedule.

Add a dead-delivery convergence pass to the erasure sweep, so every topology that
runs schedule maintenance settles it. The pass is POSITIVE-EVIDENCE-ONLY and is
therefore safe where absence-based reconciliation is not: a `dead` delivery is
durable shared state proving no generation owns the reservation. It settles only
when the job is confirmed absent or identity-mismatched (an identity-matched job
still owns the run), defers on an unknown job lookup, on an in-flight abort, and
on an in-flight resume hand-off, ignores legacy reservations with no deliveryKey,
and applies a short grace so an accepted delivery still creating its generation is
never settled mid-handoff. Auto-disable policy is deliberately left to the armed
engine; this path records the failure and frees the slot.

Deliberately does NOT touch api/server/experimental.js — the clustered entrypoint
already starts this sweep, so the convergence arrives through the existing
initializer and the shared-file footprint stays as-is.

Tests: settles a dead delivery as error under an explicitly UNSAFE topology,
leaves live deliveries alone, never settles under an identity-matched running
generation (delivery is not even consulted), defers an in-flight abort, and
ignores a reservation with no deliveryKey.

* fix(stream): refresh host-action retention on each retry attempt

Codex finding: unacknowledged terminal host-action evidence was capped at the
24h pause TTL, so a host dependency (Mongo) unreachable for longer than that let
the Redis key — and its pending marker — expire with no generation-fenced
acknowledgement, stranding the ScheduleRun where no reconciler is armed.

Measure retention from the LAST retry rather than from the terminal transition:
enumerating a pending host action IS the retry attempt, so both stores refresh
its retention as they hand it to the hook (Redis re-EXPIREs the job key; the
in-memory store stamps terminalHostActionRefreshedAt and bounds from it). Evidence
therefore survives as long as some replica is still actively retrying, while a
deployment that stops sweeping entirely still lets it age out — so this does not
reintroduce the unbounded leak the cap existed to prevent.

Test: after a failed hook, a later cleanup pass keeps the marker pending and moves
its retention basis forward.

* fix(schedules): defer settlement when the Stop barrier times out

Codex finding: waitForStopPersistence returned after its 5s poll budget even when
the Stop was still fresh and unacknowledged, and recordScheduleOutcome then went
straight on to terminalize the run — releasing its capacity, deletion, and erasure
barriers while beforePublish may still have been writing. Slow checkpoint cleanup
is indistinguishable from a dead route on that signal, so the timeout was being
treated as if the barrier had been satisfied.

The poll budget now means "undecided", not "clear". On timeout with a fresh,
unacknowledged Stop the barrier DEFERS: recordScheduleOutcome returns false
without recording, leaving the run active/preserved. Settlement then happens
either when the route acknowledges, or once the existing stale-owner cutoff
(ABORT_OWNER_PRESUMED_ALIVE_MS) authorizes a later attempt — which the loop
already treats as clear-to-settle. Callers with durable retry (the approval-expiry
host action, reconciliation) re-drive it, so a deferral converges rather than
stranding the run.

Test: a fresh Stop that never acknowledges within the budget reports not-settled
and records no outcome.

* fix(schedules): require definite delivery failure, extract its message, converge deferred Stops

Third Codex round. Three findings in code from this closeout, plus one pre-existing
P1 that is a one-line operator-safety fix.

P1 — dead-delivery settlement demanded too little evidence. `dead` does not prove a
request was rejected: the trigger host marks response timeouts and invalid success
responses `certainty: 'ambiguous'`, and the engine dead-letters those once retries
are exhausted. The erasure sweep treated every dead letter as positive evidence, so
an ambiguous one sitting over a generation a peer had accepted could terminalize the
run and release its capacity mid-flight. It now settles only on a DEFINITE rejection,
unless job absence is deployment-authoritative (safe topology), where the
confirmed-absent job is itself the evidence.

P1 — `lastError` is an `AgentTriggerDeliveryFailure` object, not a string. A
duplicated local interface declared it `string` (against CLAUDE.md's no-duplicate-
types rule), so both the sweep and the engine reconciler passed the object into the
String-typed run/schedule `error` fields; Mongoose would reject the cast, the per-row
catch would swallow it, and the run would keep its global capacity slot. The dep type
now reuses the canonical `AgentTriggerDeliveryFailure` and both call sites pass
`.message`. Re-typing immediately surfaced a stale test that had asserted a string.

P1 (pre-existing) — the base-config global stop is honored in `getLimits` via
`isRuntimeDisabled` rather than a literal `=== false`. The stop has two shapes, and
deepMerge turns base `{ use: false }` plus a principal override of `true` into
`{ use: true }`, so the literal check reported the feature enabled and Run Now
dispatched straight through fireSchedule, bypassing the operator's emergency stop.
Now the same predicate the engine gate already uses.

P2 — a Stop whose settlement DEFERRED past the poll budget had no convergence path
where no reconciler is armed. `acknowledgeScheduledStopPersistence` now optionally
re-drives the terminal outcome once the barrier clears; `recordRunOutcome` is
match-guarded and idempotent, so an owner that already settled makes it a no-op. The
abort route passes it for a running generation; a paused job still settles explicitly.

Tests: ambiguous dead letters refused under unsafe topology but settled when absence
is authoritative, definite rejections settled either way, the failure message carried
through, and the abort route's re-drive present for running / absent for paused.

* fix(schedules): converge terminal runs in clustered workers, retry suspension restore

Fourth Codex round on 74f7af8. Both findings are in code from this closeout.

P2 - a clustered worker never settled a run whose generation finished but whose
outcome write failed. `recordScheduleOutcome` retries three times and then returns
false; the owner honors that by PRESERVING the terminal job as the only surviving
evidence, and the armed engine's reconciler replays exactly that. The clustered
entrypoint arms no engine, and its sweep only covered deleting schedules
(settleAbandonedRuns) and dead deliveries - an identity-matched job was skipped
outright. So an ordinary live schedule's run stayed `started`, held its GLOBAL
capacity slot, and kept a preserved job that carries no `completedAt` and is
therefore invisible to the store's finished-job sweep: both leaked until store
expiry.

The live-schedule pass now also converges from a retained terminal job, mirroring
the reconciler branch it stands in for: honor the owner's stamped outcome over the
generic status (so a balance refusal still walks its streak rather than resetting
it), clear the reserved conversationId when the generation never emitted its
created event, and delete the retained job only AFTER the outcome write is durable.

This stays positive-evidence-only and safe in every topology. Presence, not
absence, is the evidence: an identity-matched job is authoritative wherever it is
observed - a shared store shows the real generation, a process-local store can
only be showing this process's own - which is why it needs no
canInferOwnerDeathFromMissingJob fence, unlike the absence-based paths. The
in-flight abort/resume fences still defer, so an `aborted` job cannot settle a run
whose owner may still be persisting. Both cases now share one pass over one window
rather than two, and `retainedOutcome` moved to types.ts so the sweep reuses the
engine's mapping instead of duplicating it (and stays independent of the engine).

P2 - a failed restore stranded a live account's schedules. Cancelling an account
deletion restores the suspended rows while the deletion fence is still armed and
then releases that fence; nothing re-drives the restore afterwards, so one
transient write failure left the user with silently disabled, next-run-less
schedules. The restore is now retried at the single choke point both the HTTP
controller and the CLI share. Retrying is safe because each attempt re-reads only
the rows STILL carrying the token: a partially-applied unordered write converges
on exactly the stragglers, and a fully-applied one finds nothing.

The fence is still released when every attempt fails, deliberately: retaining it
would refuse the live account's schedule writes AND make beginAgentTriggerUserDeletion
report `in_progress` forever, blocking the retry that is the convergence path (a
later attempt adopts this snapshot, so its cancel restores these exact rows). Both
callers now log the user id and suspension token so the state stays recoverable by
hand if that never happens.

Tests: retained terminal job settled and its evidence released, stamped outcome
preferred over the generic status, stamped failure reason carried, reserved
conversationId cleared for a never-created conversation, identity-mismatched
terminal job ignored, abort-in-flight deferred; restore retried past a transient
write failure and converging on a partially applied restore.

* fix(schedules): converge unprojected pauses and release replayed bookkeeping jobs

Two of the four findings I flagged as pre-existing to my closeout commits. Both are
in code this PR introduces, so merging would have shipped them; both are the same
capacity/evidence-leak class the last four rounds have been closing. The remaining
two (slotless rows escaping the per-user cap, and the non-rotating `started`
reconciliation bucket) are genuinely latent and deliberately left alone.

An UNPROJECTED PAUSE held a global capacity slot forever. The pause projection is
what moves a run row off `started`; `recordScheduleOutcome` already retries it, but
the request controller discarded the result, so three failed attempts were dropped
silently. The armed engine's reconciler replays that state, but the clustered sweep
did not: a paused job is not terminal, so the retained-job path returned without
settling, and the dead-delivery path never inspects an identity-matched job at all.
The row stayed `started` with no cutoff that would ever clear it.

The call site now surfaces the failure, and the sweep converges it, mirroring the
reconciler's pause branch: project `requires_action` (which frees the slot) but do
NOT release the job's evidence — unlike a terminal job it is still live, awaiting an
approval. The resume hand-off fence still defers, so re-projecting cannot release a
slot a continuation just claimed.

The BOOKKEEPING REPLAY pass leaked its retained job. A run reaches that pass only
because its owner crashed before bookkeeping — which is also before it could release
the job it retained for exactly this recovery. The active-run pass clears its own;
this one never did, and a preserved job is deliberately kept WITHOUT `completedAt`
so the store's finished-job sweep cannot reap it early, so nothing else ever would.
It now clears after `finalizeBookkeeping` succeeds — identity-guarded, a no-op when
no job is retained, and skipped entirely when the replay itself failed, since the
retained job is the only surviving evidence in that case.

Tests: pause projected and the slot freed while the live job's evidence is kept,
paused job deferred during a resume hand-off, retained job released once replayed
bookkeeping is durable, and retained job kept when the replay fails.

* fix(schedules): fence the clustered pause replay against a concurrent resume claim

Codex round 5, on code I added in f735341. The finding is correct and the exposure
is one I introduced.

The pause replay lives in a sweep that runs in EVERY clustered replica, so several
sweepers can observe the same unprojected pause. Its guards were all derived from an
in-memory row SNAPSHOT: hasResumeHandoffInFlight reads the snapshot's
resumeClaimedAt, and recordRunOutcome's pause branch matched any row currently in
`started`/`requires_action` with no fence of its own. The race: sweeper A projects
the pause and frees the slot; the owner's approval then claims a fresh one
(markRunResumeClaimed takes the row to `started` WITH resumeClaimedAt in one write);
sweeper B, still holding the pre-projection snapshot, passes its hand-off check and
replays — `$unset: { capacitySlot, resumeClaimedAt }` under a continuation that is
already running. The run reverts to `requires_action` while its generation proceeds
outside global capacity.

The engine's reconciler makes the same call and has the same snapshot-derived guard,
but v1 arms exactly one engine, so it has no concurrent racer; the sweep is the first
thing to run this transition in parallel. Left the engine alone rather than widening
the change: its `requires_action` re-affirmation is deliberate and single-writer.

Fixed where the race is, in the write itself. `recordRunOutcome` takes an optional
`requireNoResumeClaim`, which adds `resumeClaimedAt: { $exists: false }` to the pause
filter, and the sweep sets it. Because the stamp is written in the SAME update that
moves the row to `started`, its absence is atomic proof no resume owns the row. The
flag is deliberately NOT set by the generation owner: its own re-pause legitimately
clears the stamp as the hand-off's completion signal.

The fence cannot block the recovery it exists to enable: markRunResumeClaimed only
matches `requires_action`, so a genuinely stuck `started` row can carry no resume
claim — it is in fact blocking its own approval until this replay frees it.

Tests: a replay from a stale snapshot leaves a resume-claimed row's status, slot, and
claim stamp intact, while a stuck row with no claim still recovers; and the sweep is
asserted to send the fence.

* fix(schedules): fence stale resume claims by age, not existence

Codex round 6, on the fence I added in ee00c60. Correct again, and the defect is
the mirror image of the one it fixed.

The fence was an EXISTENCE check (`resumeClaimedAt: { $exists: false }`) while its
caller's guard is a FRESHNESS check (hasResumeHandoffInFlight, bounded by
RESUME_HANDOFF_STALE_MS). They agree while a claim is fresh and disagree once it is
abandoned: a worker that dies after markRunResumeClaimed takes the row to `started`
and stamps resumeClaimedAt — but before the continuation resumes or
releaseRunResumeClaim rolls it back — leaves the stamp set forever. Past the bound
the sweep correctly stops deferring and tries to recover the row, but the write
rejected it purely because the field still existed. The row stayed `started` holding
its global capacity slot, and its approval was unresumable for good, since
markRunResumeClaimed only matches `requires_action`. That is exactly the stuck state
this replay exists to clear, so the fence had reintroduced it for the crashed-resume
case.

`requireNoResumeClaim: boolean` becomes `resumeClaimStaleBefore: Date`, and the
filter matches a row with no claim OR a claim older than that cutoff. The sweep
passes the SAME bound its in-flight check uses, so the two can no longer disagree.
A genuinely racing claim is by construction fresh — it is created after the sweeper's
snapshot — so the race from round 5 stays closed.

Tests: a row whose resume claim was abandoned by a dead worker now recovers (status,
slot and stamp all cleared), alongside the existing two — a fresh claim still repels
a stale-snapshot replay, and an unclaimed stuck row still recovers.

* feat: surface interrupt-steer escalation on waiting messages

The interrupt & steer feature shipped reachable only through the
composer chord, the send-button hovercard, and the composer button; a
message already waiting (queued for after the run, or steered and
parked at the next tool boundary) had no path to it. Both waiting
surfaces now carry one:

- Queued rows get an icon-only ZapOff escalation button beside the
  existing Steer primary. It routes through sendQueuedNow, which now
  takes a preempt option on its live-run path. The tooltip teaches the
  composer chord, derived through resolveComposerKeyDown so a rebound
  or yielded chord is never advertised.
- In-flight steer bubbles get an "Interrupt now" overflow entry with
  the same race rules as Edit: reclaim first, and only a `reclaimed`
  outcome resubmits (via retrySteer with preempt, swapping the chip
  for an interrupting one). `applied` and run-ended-mid-reclaim
  outcomes stop at the existing informational toasts, so the words can
  never land twice. Not offered on a steer already preempting.
- Every during-run overflow menu gains an "Always interrupt instead"
  toggle for steerInterruptsByDefault, next to the existing steer/queue
  default toggle. MenuEntry supports disabled for the new entries.

Only one interrupt can be unresolved at a time: while one preempt is
pending (or the run is paused on approval, where the server 409s),
every escalation control disables instead of racing the same seal.

Ten new tests across both surfaces; 381 green in the affected suites.

* fix: lock escalation across its reclaim window, keep the paused control visible, label as steer

Codex round 1, all three findings.

P2, escalation race. The single-interrupt invariant had a window between
clicking "Interrupt now" and the reclaim resolving, where no preempt
chip existed for the chip-derived gate to see: two bubbles escalated
back-to-back could both resubmit. A shared escalating flag (Jotai,
per-conversation) now covers the window and disables every escalation
control on both surfaces, and a fresh recheck before resubmitting
catches an interrupt armed elsewhere meanwhile (composer chord, queued
row); those words re-home to the queue with an informational toast
instead of breaking the invariant.

P2, unreachable paused state. canSteer is defined as
hasRealConvoId && !pausedOnApproval, so gating the button on canSteer
removed it exactly when it was meant to render disabled; the test only
passed on an impossible stub combination. The render gate is now
duringRunActive && (canSteer || pausedOnApproval), and the test uses the
real invariant.

P2, label semantics. "Interrupt & send now" borrowed the name of the
hard-abort action; this one preserves the partial answer and steers.
Renamed to "Interrupt & steer now" (com_ui_interrupt_steer_now).

Both behavior fixes counterfactually verified; 384 tests green across
the affected suites.

* fix: disable bubble escalation while the run cannot accept a steer

Codex round 2, one P2. Answer mode (ask_user_question) sets
duringRunActive false while pausedOnApproval stays false, since that
flag only detects approval-bearing tool calls. The bubble's escalation
entry stayed enabled there, so clicking it cancelled a healthy waiting
steer and the preempt resubmission bounced off RUN_PAUSED, degrading
the words to the queue. The entry now also disables on
!duringRunActive, matching the queued-row control's gate.

Counterfactually verified: reverting the gate fails the new
answer-mode test.

* fix: recheck live run state after the reclaim, not just at the click

Codex round 3, one P2, and it is the round-1 recheck principle applied
one level deeper: the entry-time disable cannot see a run that pauses
(tool approval, answer mode) while the reclaim round-trip is in flight,
and the .then closure held the render's stale steering controls, so the
resubmit would fire into a RUN_PAUSED rejection after the reclaim had
already surrendered the steer's boundary slot.

The escalation continuation now reads the LIVE controls through a
latest-ref: if the run can no longer accept a steer, the words re-home
to the queue with an informational toast instead of resubmitting, and
the resubmit itself also goes through the live controls.

Counterfactually verified: reading the stale closure instead of the ref
fails the new mid-reclaim pause test.

* refactor: make escalation one atomic server-side arm, in place

Codex round 4: four P2s, every one an interleaving of the same window —
escalation as reclaim-then-repost is a compound, non-atomic operation
whose continuation must revalidate the world (FIFO position lost, ref
assigned too late, no run fence, competing bubble actions). Rounds 1-3
patched that window with a lock and rechecks; round 4 shows the window
itself is the defect, so this removes it instead of guarding it again.

Escalation is now POST /chat/steer/arm: the server flips preempt on the
EXISTING queued item in one atomic store op (new IJobStore.armSteer; a
decode-patch-encode LSET Lua on Redis, an in-place mutation in memory),
fenced to the validated generation and refused once the queue closes.
The handler mirrors the steer POST's preempt contract exactly: durable
flag gated on the owner's recorded capability, volatile requestPreempt
fire-and-forget because the durable flag is the truth resume/handover
re-arm from.

By construction this resolves all four findings: FIFO survives (the
item never moves; the whole queue still drains in instruction order at
the seal), there is no continuation to hold stale controls, the store
op is fenced to the original run, and a competing Edit/Queue/Cancel
either beats the arm (armed:false, chip untouched) or operates on the
armed item, whose cancel already disarms.

The client escalation entry becomes one mutation: armed:true relabels
the chip in place (same steerId, same position), PREEMPT_UNSUPPORTED
and lost races toast honestly, and the round 1-3 machinery — the
escalating lock atom, the latest-ref, the post-reclaim rechecks and
their two toast strings — is deleted rather than extended.

Verified: 7 new handler tests on the real in-memory manager (including
FIFO preservation and the stale-generation fence), 2 Redis integration
tests against real Redis (in-place arm keeps order and every field;
missing/stale/closed all refuse), client suites 396 green.

* fix: decide capability inside the atomic arm, neutralize the lost-race toast

Codex round 5, both findings, both edges of the new arm design rather
than its mechanism.

P2, capability TOCTOU. A HITL resume on a rolling deploy rewrites
preemptCapable for the SAME generation, so the handler's read could go
stale between validation and the flag flip, arming a steer the live
owner cannot seal. armSteer now returns armed | missing | incapable,
with the owner's live capability part of the same atomic predicate as
the generation fence (HGET preemptCapable inside the Lua; the flat job
field, not a metadata blob — the in-memory store reads the same field).
The handler's pre-check is deleted rather than kept alongside; the
store predicate is the single source. New handler test rewrites the
capability after queueing and expects PREEMPT_UNSUPPORTED with the item
left unflagged; the Redis guards test now asserts the incapable refusal
against real Redis.

P2, ambiguous toast. armed:false covers injected, cancelled, re-homed,
and run-over alike, so telling the user the message "already reached
the agent" claimed one specific outcome. The lost-race branch now uses
a neutral message (com_ui_steer_arm_lost_race) and defers to the events
for what actually happened.

* fix: flip the escalation lock synchronously before the arm request

Codex round 6, one P2. Round 4 deleted the escalating flag along with
the reclaim continuation it guarded, but that left the one-interrupt
gate blind during the arm request's own round trip: the chip-derived
check cannot see an arm until its response relabels the chip, so on a
slow connection two bubbles could both arm before either response
landed. Double-arm is harmless server-side now (the run seals once and
drains the whole queue in order), but every escalation control
advertises "one interrupt at a time" by disabling, and the controls
must tell the truth.

The per-conversation escalating flag returns as a pure UX gate: set
synchronously at click, before the mutation, cleared on settlement, and
folded into interruptPending on both surfaces. Unlike its round 1-3
ancestor there is no continuation behind it to guard and no recheck to
pair with it.

Counterfactually verified: without the synchronous set, the two-bubble
race test arms twice. 207 tests green across the Chat Input suites.

* test(e2e): cover escalation of waiting messages through the real seal

Three mock-harness tests on E2E_SLOW_REPLY, a 160-chunk stream with no
tool boundary, so an in-thread steer part can ONLY come from a genuine
mid-stream seal — which makes each test a behavioral proof rather than
a UI check:

- Queued row escalation: the ZapOff button turns a waiting queued
  message into a preempt-armed steer (202 echoes preempt: true) that
  seals and injects, where the sibling steering.spec test proves the
  unescalated path waits for run end instead.
- Bubble in-place arm: an ordinary steer (202 with no preempt echo)
  waits as a bubble, POST /chat/steer/arm answers armed: true, the
  bubble relabels in place (same single bubble, same text, escalation
  no longer offered on reopen), and the armed steer seals mid-stream.
- Always-interrupt toggle: flipped from a waiting row's overflow menu,
  plain Enter now produces a preempt: true steer that seals in the SAME
  run, and the menu offers the way back. An afterEach clears the
  localStorage preference so a mid-test failure cannot leak
  preempt-by-default into the rest of the serial suite.

All three verified locally through the full harness (real backend, mock
LLM, seeded DB): 3 passed in 27s.

* feat: dedicated escalation arrow + shortcut, menu split into actions and preferences

The escalation was still half-hidden: the bubble only offered it inside
the overflow menu, and the tooltip taught the composer chord, which does
a different thing (interrupts with typed text, not this chip). Three
changes make it a first-class command:

- A shared EscalateNowButton (circular arrow, ghost-bordered like the
  composer's interrupt control) is always visible on BOTH surfaces:
  beside each queued row's Steer primary and on every waiting steer
  bubble next to its menu. It disappears once a steer is interrupting.
- A dedicated registry shortcut, escalateSteer (Cmd/Ctrl+Shift+.),
  editing-allowed and rebindable like every other action. Deliberately
  NOT an Enter chord: the composer owns every Enter chord, and the
  yield design rests on no default binding using Enter besides submit.
  Its handler clicks the newest enabled arrow control (bubbles beat
  queued rows), so the shortcut can never diverge from the button, and
  the arrow's tooltip teaches THIS command via the registry display.
- The overflow menus separate one-off actions from sticky behavior
  changes: Edit, Cancel, Queue, then a smaller "Preferences" section
  holding the queueing and always-interrupt toggles, each with the
  standard InfoHoverCard reusing the Settings panel's descriptions.
  "Interrupt & steer now" leaves the menu entirely.

386 client tests green, including a menu-structure test locking the
order and the absence of the escalation entry; bubble escalation tests
drive the visible arrow. The e2e spec's bubble test now clicks the
arrow, and a fourth test drives the dedicated shortcut end to end
through a real mid-stream seal.

* style: bind the escalation arrow to its message (variant A anatomy)

Two same-weight circles in a row read as one control group, leaving the
arrow's ownership ambiguous, and a floating arrow stops meaning anything
once several messages stack. The shared control now carries variant A's
anatomy: a thin divider binds a small SOLID arrow (filled, inverted) to
the message region on its left, and the menu ellipsis stays a bare
glyph, so the two affordances can no longer blur together — and the
divider+arrow pairing repeats cleanly per chip at N messages.

* chore: drop the unused within import CI lint caught

* fix: advertise the escalation shortcut only while the control is live

Codex on the e2e head, one P2: the tooltip appended the chord hint even
while the button was disabled, advertising a shortcut that does nothing
during an approval pause. The flagged control (InterruptNowButton) was
since replaced by the shared EscalateNowButton, which inherited the
pattern; the successor now omits the chord whenever the control is
disabled, matching the rule the during-run hovercard already follows.

🧭 feat: Mid-Run Steering and Queued Messages for Agent Runs (#14220)
* 🧭 feat: Mid-Run Steering and Queued Messages for Agent Runs

Steering: submit a message while a run is generating; the server queues
it in the job store (cross-instance) and a run-scoped PostToolBatch hook
injects it into graph state at the next tool-batch boundary, records an
inline 'steer' content part on the response (replayed as a user message
on later turns), and streams on_steer_applied to the client.

Queuing: messages composed during a run auto-send as normal follow-up
turns after clean completion (one per final event, FIFO); user aborts
leave them as chips unless armed by interrupt-and-send.

Requires hook injectedMessages support in @librechat/agents
(danny-avila/agents#299); hard-gated via a capability probe so older
SDKs 501 the steer route instead of draining and dropping messages.

* 🧵 fix: Harden Steering Against Finalization Races and Route Guard Gaps

Addresses local Codex review findings on the steering feature:

- Close-and-drain the steer queue atomically at finalization (final event,
  abort) so a steer POST racing teardown is rejected instead of 202-ACKed
  and then silently cleared; the closed flag lives on the job hash and is
  reset when a replacement job reuses the stream id.
- Clear inherited steer queues on createJob — a job replacement must not
  drain the replaced run's messages.
- Keep steers queued across a HITL pause instead of draining them into
  ephemeral client state: resumeState re-seeds chips on reload and the
  resumed run injects them at its first tool boundary (steers key TTL now
  extends to the approval window; on_steers_pending event removed).
- Queue the NO_ACTIVE_RUN steer fallback while the final SSE is still
  settling — a direct send would be dropped by ask()'s in-flight guard.
- Reconcile the 202 ACK against on_steer_applied events that beat it over
  the SSE, so a chip can't be re-minted after its removal event passed.
- Allow the per-send Steer override when the default action is queue.
- Apply the configured message rate limiters and the PII filter to
  POST /chat/steer — a steer is model-bound user text.

* ✅ ci: Assert Steering Capability Probe Against the Installed SDK

CI installs the published @librechat/agents pin (pre-injectedMessages),
where isSteeringSupported() is legitimately false — the probe test now
asserts it mirrors the installed SDK's capability flag instead of
hardcoding the capability-bearing build's value. Verified against both
the published 3.2.61 dist and the agents#299 build.

* 🛟 fix: Preserve Steer Text Across Run-End, Error, and Abort Races

Codex round 2 (4 P2s):
- Applied-steer-id set survives run end (capped at 100) and converted
  ids join it, so a 202 ACK that lands after final/abort drops its chip
  instead of re-minting a stranded pending one.
- Failed runs no longer strand acknowledged chips: both error paths
  convert local pending chips to queued follow-ups (chip text is
  client-local), and the server closes the steer queue before emitting
  the error so a racing steer POST gets 404 fallback instead of a 202
  whose payload dies with the job.
- sendQueuedNow keys on steer availability, not the default action —
  send-now on a queued chip is an explicit override for queue-preferring
  users.
- Stop path consumes pendingSteers from the abort HTTP response as a
  fallback for the SSE final event it may close before processing;
  conversion is deduped so double delivery is a no-op (shared
  useSteerConvert hook).

* 📎 feat: Carry Attachments Through During-Run Queued Messages

Steering stays text-only (SDK injection, inline STEER part, and replay
are all text), so a during-run submit with media now queues the whole
message as one unit instead of silently stranding the files:

- QueuedMessage gains `files`; composer attachments are consumed into
  the queued item at queue time (steerFromComposer / queueFromComposer /
  interruptAndSend), fixing the latent hazard where lingering composer
  files glued onto whatever `ask` vacuumed up next.
- Enter-steer with attachments degrades to queue with an explanatory
  toast; the per-send menu routes through the same composer-aware
  wrappers.
- The drain and sendQueuedNow pass the item's files as `overrideFiles`;
  media items never steer (send as a normal turn when idle, re-front
  otherwise). ask() no longer clears composer state for caller-supplied
  overrideFiles — only regenerate keeps that behavior.
- During-run submits hold while uploads are in flight, mirroring the
  send button's filesLoading gate; queued chips show a paperclip count.

* 🎛️ feat: Rework During-Run Chips into Action Rows

Full-width rows above the composer (reference-UI parity): each queued
message shows a primary Steer/Send-now action, delete, and a "…" menu
with Edit message (restores text + attachments into the composer) and a
Turn on queueing/steering toggle that flips the Enter default. Steer
rows share the layout with status text; failed steers keep retry /
edit / queue-convert. The per-send menu gains the same default toggle.
Queued file refs now retain filename + bytes so edit-restore rebuilds
real composer entries (draft-recovery shape).

* 🖇️ feat: Steer With Attachments (Multimodal Mid-Run Injection)

Steering now carries media end-to-end instead of degrading to queue:

- The steer POST accepts sanitized attachment refs (cap 10; only
  file_id is trusted — the drain re-fetches owner-scoped and re-derives
  everything else). SteerQueueItem/TPendingSteer/SteerContentPart carry
  `files` refs; encoded data is never persisted or queued.
- New api/server/services/Files/steering.js decouples attachment
  building from the request path: encodeSteerContent reuses the exact
  per-turn pipeline (addFileContextToMessage + processAttachments'
  single-pass categorize/encode, SDK formatMessage assembly,
  prependFileContext for extracted text) with zero new encoding code.
  buildSteerMedia feeds the drain hook's new buildMedia seam (any
  failure degrades that steer to text-only — words always land);
  stampSteerPartMedia re-encodes past steer parts per turn with ONE
  batched owner-scoped fetch and stamps a transient `media` array,
  replaced immutably so it can never leak into a save. Replay honors
  resendFiles like regular message media.
- The SDK's formatAgentMessages (the formatter agents actually use)
  gained the steer replay branch on the PR branch; the local
  formatMessages.js branch now mirrors the media preference.
- Client: steerFromComposer consumes composer files into the POST,
  chips/seeding/conversions carry files everywhere (retry, queue
  convert, abort/error recovery), queued media items steer for real,
  and SteerBubble renders the steered attachments inline.

* 🧵 fix: Harden Steer Recovery Races and Drain Isolation

Codex round 3 (7 fixes):
- A 202 ACK landing after the run ended converts straight to a queued
  follow-up (server queue is gone; no event will ever resolve a pending
  chip for a finished run). Covers stream errors with in-flight POSTs.
- A Stop that lands pre-completion can arrive as a final with
  unfinished:true and no aborted flag — runEnd now treats it as aborted
  so queued messages are not auto-sent against the user's Stop.
- Leftover-steer conversion merges chronologically by createdAt instead
  of appending, preserving the order the user composed.
- Auto-drained queued messages pass explicit (possibly empty)
  overrideFiles/overrideQuotes/overrideManualSkills: a drain can no
  longer vacuum up files, quotes, or skill picks staged in the composer
  for the user's NEXT message (ask() treats overrideFiles != null as
  authoritative).
- Failed-steer Retry and resume-on-load chip restoration keep the
  steer's attachments.
- The job-replacement guard moved INSIDE the store's atomic
  drain/close-and-drain (Lua createdAt compare; in-memory equivalent):
  a stale run's hook or finalization can neither consume, close, nor
  steal a replacement job's steer queue, and the drain hook drops its
  separate check-then-drain round trip.

* 🧰 refactor: Typed Steer Controller, Single-Query Media Pass, Round-4 Fixes

Codex round 4 + efficiency tightening in one pass:

- Moved the steer guard ladder (validation, file sanitization via a
  shared toSteerFileRef picker, ownership/tenant checks, status-guarded
  enqueue) into packages/api as handleSteerRequest; api/steer.js is now
  a thin wrapper. Ladder covered against the REAL in-memory job manager
  in request.spec.ts; the api spec pins only the wrapper contract.
- Folded the steer replay stamp into the turn's ONE historical-files
  query: collectHistoricalFileRefs also gathers steer-part refs, the
  owner-scoped doc map rides client state, and stampSteerPartMedia
  consumes it (no second round trip) while encoding parts in parallel.
- Stamped steer media now counts against the run budget (existing
  multimodal counter over the non-text parts, folded into
  indexTokenCountMap/promptTokens after the stamp).
- Steer route runs the PII filter BEFORE moderateText, matching chat.js
  so blocked sensitive text never reaches the external moderation API.
- Interrupt & send survives the abort-response-beats-SSE-final race:
  stopGenerating writes the run-end signal itself when the one-shot
  interrupt flag is armed and no signal landed (double-fire safe).
- Resume reconciles chips against the server's still-queued list even
  when EMPTY, clearing chips for steers applied while disconnected.
- The local formatter's steer flush preserves non-text assistant parts
  (array-content AIMessage) instead of folding to text.

* 🔒 fix: Replay-Aware Capability Gate and Round-5 Race Closures

- isSteeringSupported now requires BOTH halves of the SDK contract:
  injection (HOOK_INJECTED_MESSAGES_CAPABLE) AND replay
  (ContentTypes.STEER, shipped in the same SDK commit as the
  formatAgentMessages steer branch). An SDK that can inject but not
  replay 501s the steer route — no release window can create steer
  parts that would leak into provider-facing assistant content.
- The local formatter mirrors the SDK's anchor reset: a post-steer
  tool_call mints a fresh AIMessage instead of attaching to the
  pre-steer anchor (invalid provider ordering).
- Queued-chip send-now and the NO_ACTIVE_RUN fallback pass explicit
  (possibly empty) overrideFiles so an idle send can't vacuum composer
  files staged for a different draft.
- Redis createJob deletes the stale steer list BEFORE the replacement
  hash is written as running — a steer 202-accepted against the new job
  can never be wiped by the reset.
- Resumed-turn finalization mirrors the normal path's terminal drain:
  createdAt-guarded close-and-drain, leftovers ride the resumed final
  event as pendingSteers instead of being cleared by completeJob.
- buildSteerMedia restores composer order over the $in result so
  multi-attachment steers reach the model in the order the user saw.

* ⚛️ fix: Atomic Job Replacement and Boundary-Clean Steering Module

Codex round 6 (5 fixed, 1 standing deferral):
- createJob resets the steer queue and writes the job hash in ONE
  same-slot Lua script (JOB_CREATE_LUA): a steer POST can no longer
  interleave between them on cluster, so a steer accepted against one
  run can never be drained into another. Redis-validated.
- The steering media pipeline moved to packages/api
  (agents/steering/media.ts) with injected getFiles and a structural
  client interface — /api keeps zero steering logic; specs ported to
  the DI seam.
- handleSteerRequest checks the job BEFORE the capability gate: a steer
  racing completion on an unsupported SDK gets 404 (send-now) instead
  of a 501 queue with no run-end signal left to drain it.
- useQueueDrain binds to the active conversation: navigating away
  between the final SSE and the drain effect leaves the signal
  unconsumed instead of submitting A's follow-up into B; the drain
  fires on return.
- abortJob closes and drains the steer queue BEFORE the content
  snapshot, so a drain-hook apply that lands pre-drain is captured
  inline rather than lost between the snapshot and the terminal drain.

* 🚦 fix: Parked Run-End Signals, Interrupt Priority, Settled-Run Fallbacks

Codex round 7 (5 fixes):
- Run-end signals for a non-active conversation are PARKED per
  conversation instead of squatting the shared index slot: a later run
  finishing on the same pane can no longer overwrite them, and the
  parked drain fires when the user returns.
- "Interrupt & send" front-inserts carry a priority flag that outranks
  createdAt when abort leftovers merge back chronologically — the
  urgent redirect drains first, not the oldest steer.
- STEER_UNSUPPORTED/RUN_PAUSED/QUEUE_FULL rejections landing after the
  run settled mirror the NO_ACTIVE_RUN fallback and send immediately
  (queueing would strand the text with no run-end signal left); on the
  pinned SDK this is the common Enter-near-run-end path.
- A failed abort (e.g. 404 when the run completed first) still signals
  the interrupt drain, so the queued interrupt message can't strand and
  the armed flag can't leak onto a later run.
- Steered-image fallback alt text is localized (com_ui_attached_image).

* 📌 chore: Adopt Published @librechat/agents Types Post-Bump

dev's pin bump to ^3.2.62 (the release carrying injection + steer
replay) landed via merge; the steering runtime now uses the SDK's real
InjectedMessage/hook-output types instead of the local structural
mirrors that bridged the pre-publish window. The two-half capability
probe stays as the defensive gate for mismatched deployments — and the
capability spec now exercises its TRUE path against the published
package in CI.

* 🛅 feat: Park-and-Claim Steer Recovery + Host-View Content Reads

Codex round 8 (6 fixed incl. both P1s, 1 push-back):
- The long-deferred no-subscriber gap is closed: every terminal drain
  (final, aborted-final, error, abortJob, resumed finalize) PARKS
  acknowledged leftovers on the job hash (unrecoveredSteers), and the
  status route claims them exactly once for inactive jobs — a client
  that closed/reloaded past the transient final event restores its
  steers as queued chips within the post-terminal TTL. A replacement
  run clears the parked copy (a live client started it).
- Same-instance content reads are steer-complete: RedisJobStore now
  caches the HOST content array (WeakRef) via setContentParts and
  prefers it over the SDK graph cache, whose view never contains
  host-authored steer parts; the graph fallback splice-INSERTS steer
  chunks at their recorded host-view indices (the graph array is
  unshifted, so assignment would overwrite SDK parts).
- Replay token accounting now counts prepended file-context text: full
  stamped content minus the steer body (already counted), so large
  steered documents hit the budget instead of bypassing pruning.
- The queue drain restores an item when ask() refuses without sending
  (history not yet in cache after navigating back) — text is never
  silently dropped.
- The armed interrupt flag travels WITH a parked run-end signal, so
  another run on the same pane can neither consume nor clear it.
- parseTextParts extracts steer text (search indexing / audio).

* 🎛️ refactor: Single Send Slot + In-Thread Steer Messages

- Merge the during-run send affordance into the send/stop button slot:
  with composer text the send button replaces Stop (Enter = default
  action), hover reveals Steer/Queue/Interrupt rows with shortcuts;
  drop the separate DuringRunActionsMenu chevron
- Add during-run keyboard chords: Cmd/Ctrl+Enter = non-default action,
  Alt+Enter = interrupt & send (plain-Enter submitters only)
- Render steers as standard user messages in the thread: SteerPart
  (icon + author header + user text presentation) replaces the
  SteerBubble, and submitted steers appear immediately at the projected
  injection point via the PendingSteers slot on the streaming message
- Keep composer rows only for recoverable states: failed steers
  (retry/edit/queue) and queued follow-ups

* 🩹 fix: Keep the Replacement Submission Alive Across Abort Settlement

The aborted run's final SSE event fires before the abort HTTP response
resolves, so an armed interrupt & send drains and starts the NEXT
submission while the abort POST is still in flight. The response
handler's unconditional clearAllSubmissions() then reset the new
submission, aborting its stream attach before the subscribe — the
follow-up ran and persisted server-side but the live placeholder
finalized empty (content appeared only after reload).

useAbortCleanup captures the submission before the abort round-trip
and both settlement paths (success and 404-catch) clear only when the
captured submission is still current; a replacement stays untouched.
Plain Stop behavior is unchanged.

* 🧭 test: Playwright E2E for Mid-Run Steering and Queuing

- Add e2e/specs/mock/steering.spec.ts: steer mid-run (202 + immediate
  in-thread pending part + real MCP tool boundary + words survive run
  end), Cmd/Ctrl+Enter queue with auto-send after clean completion,
  and Alt+Enter interrupt & send with the follow-up streaming into the
  live view
- Add the E2E_STEER_TOOL_REPLY fake-model marker: slow preamble, a
  real remember_fact MCP tool call (PostToolBatch boundary), then a
  final turn
- Test 1 pins the run-end degradation contract while the SDK's
  top-level agentId stamping bug blocks live injection; its header
  documents the assertions to flip once the fixed SDK is pinned

* 🧷 fix: Job-Independent Steer Recovery + Expiry and Resume-Gap Parking

Codex round 10: the park-and-claim recovery had lifecycle holes.

- Move parked steers off the job hash onto their own bounded-TTL store
  key (JOB_CREATE_LUA resets it; deleteJob leaves it alone): the default
  completeJob path deletes the job record immediately, and the Redis
  read path never deserialized the old hash field — recovery previously
  worked only with STREAM_KEEP_COMPLETED_JOBS on the in-memory store
- Carry the owner identity inside the parked payload and authorize the
  claim against it, so the status route recovers steers on its jobless
  branch too (the common reload-after-terminal case); a non-owner claim
  returns nothing and re-parks the payload
- Park queued steers on approval expiry: snapshot the frozen queue
  before the requires_action→aborted CAS (whose terminal cleanup drops
  the steers key) and park only when the CAS wins
- Mirror the terminal drain/park block in resume.js's failure path,
  which previously let completeJob's backstop clear 202-accepted steers
- Close the Redis snapshot→subscribe resume gap: re-peek the queue
  after attaching and re-surface missed on_steer_applied events from
  the durable content view (synthesizeAppliedSteerEvents), updating
  resumeState.pendingSteers to the live queue

* 📌 chore: Require @librechat/agents 3.2.63 + Applied-Steer E2E Contract

- Bump the @librechat/agents pin to ^3.2.63 in api/ and packages/api/:
  it scopes the hook agentId marker to subagent child graphs, so the
  steering drain hook fires at top-level tool-batch boundaries and
  mid-run injection is active (danny-avila/agents PR 307)
- Flip e2e steering test 1 from the documented degradation contract to
  the applied-steer contract: the optimistic in-thread part transitions
  to the persisted part at the tool boundary and survives inside the
  response after run end, with no queued follow-up turn

* 🎗️ feat: Steered Messages Join the Message-Nav Ribs

Steers are user messages, so they get their own clickable rib on the
navigation rail, interleaved at their in-thread position inside the
response that absorbed them (one DOM query in document order). SteerPart
anchors itself as #steer-<id> with a steer-render marker — both the
optimistic pending entry and the persisted part — and the rib carries
the user role label with a preview drawn from the steer's text body,
skipping the author header.

* ❎ feat: Cancel a Queued Steer Before Injection + True User-Message Alignment

- Add POST /chat/steer/cancel: removes ONE still-queued steer by id via
  an atomic list rebuild (Redis Lua preserves order and TTL), authorized
  against the job owner; removed:false is advisory — the cancel lost its
  race to the drain or the run end, never an error
- Surface an × on the in-thread pending steer (server-acknowledged
  entries only): optimistic removal, restored if the POST fails since
  the server would still inject the words
- Outdent SteerPart past the response's icon column so steers sit flush
  with top-level message rows, reading as regular user messages

* 🧯 fix: Round-11 Recovery Hardening + Provider-Free Pending Slot

- Reconcile the resume steer gap by steerId SETS, not queue length — a
  steer added in the gap (or an equal-length drain+enqueue swap) now
  refreshes resumeState.pendingSteers and still synthesizes the missed
  on_steer_applied events
- Make completeJob's terminal backstop park: direct error-path callers
  without the controllers' close-and-park no longer silently clear
  202-accepted steers (createdAt-guarded closeAndDrain + owner park
  before the terminal write)
- Persist the steer part BEFORE media encoding in the drain hook: an
  abort inside the encode window can no longer lose a file-steer (the
  part refs come from the enqueue-sanitized item; replay re-encodes
  per turn unchanged)
- Move the parked-claim owner check INSIDE the atomic store claim
  (substring gate in the Lua / in-memory equivalent): a non-owner probe
  can no longer transiently delete the recovery payload; the app-side
  parse stays authoritative
- Park queued steers in BOTH stores' own requires_action expiry
  cleanup, which bypassed the manager-level sweep
- Sweep expired parked steers from the in-memory store's periodic
  cleanup; restore a queued chip when send-now's submit is refused;
  upsert steer ACKs so an SSE reconnect reseed cannot duplicate chips
- Mount the cancel mutation per steer item so the pending slot needs no
  QueryClient on ordinary streaming renders (fixes the CI failure in
  ContentParts.integration.test)
- Skipped delivery-gated parking (finding 8): transport receiver counts
  cannot prove browser delivery, and gating the only durable copy on
  them trades cosmetic chip resurrection for real text loss; the window
  is already bounded by claim-on-read, createJob reset, and the TTL

* 🩺 fix: Annotate PARKED_STEERS_TTL_MS for isolatedDeclarations

tsdown's d.ts generation requires explicit types on exported consts
with computed initializers; tsc --noEmit does not run that check, so
the round-11 export slipped past local verification and broke Build
packages (and every downstream CI job that consumes the built dist).

* 🛟 fix: Round-12 Terminal-Path Recovery + Durable Steer Events

- Park queued steers before the stale-running reap deletes a crashed or
  hung job in BOTH stores — the one terminal path with no controller
  finalization; requires_action expiry parking refactored onto the same
  snapshot/park helpers
- Enqueue instead of dropping when a steer fallback send is refused:
  both the NO_ACTIVE_RUN branch and the settled-run rejection branch
  now observe sendNow's false return
- Recover on the SSE reconnect-404 terminal path: convert local pending
  steers to queued, claim parked steers via /chat/status, and write a
  non-completed run-end signal so interrupt flags release without
  auto-sending an unknown outcome
- Fall back to a positive parked-recovery TTL when completedTtl is 0
  (SET EX 0 is invalid and silently killed recovery)
- Make on_steer_applied durable before publish: emitChunk gains a
  durable option that awaits the chunk-log append (best-effort) ahead
  of the transport publish; the default delta path stays fire-and-forget

* 🔐 fix: Round-13 Steer Authorization + Trusted File Refs

- Resolve client-supplied steer file refs against the DB owner-scoped
  at enqueue and queue only DB-derived shapes (same filter as the
  injection fetch, shared via refs.ts); any unresolved id fails loud
  with 400 — spoofed type/filepath metadata can no longer be persisted
  into assistant content or rendered in chat/share views
- Enforce agent authorization on /chat/steer against the ORIGINATING
  run's job identity: the chat path's role gate (AGENTS:USE, with the
  same non-agents-endpoint skip) plus the per-agent ACL check with the
  capability bypass — revoked access mid-run can no longer inject;
  cancel stays ownership-only (nothing model-bound)
- Mark steered uploads used after a successful enqueue (owner-scoped,
  best-effort) so the upload-window TTL cannot reap a file the
  persisted steer part references
- Consume the parked recovery copy after live delivery: converting
  final/abort/error pendingSteers fires one owner-gated claim-on-read,
  so dismissed chips can no longer resurrect on a later reload

* 🎙️ fix: Round-14 Composer-Context Fidelity + TTS and Queue-State Gaps

- Keep steer text out of generic assistant text extraction:
  parseTextParts excludes STEER parts by default with an includeSteer
  opt-in for the full-record surfaces (Meili indexing, aborted-response
  persistence) — TTS callers no longer speak the user's own mid-run
  words
- Mark queued uploads used at enqueue time via a minimal owner-scoped
  POST /files/usage (fail-closed without a user; upload limiters do not
  apply to a metadata touch), fired once wherever composer files enter
  the queued state — the upload-window TTL can no longer reap a file
  waiting out a long run or approval pause
- Carry quote chips and manual skill picks on queued items: captured
  and consumed from the composer at queue/interrupt time exactly like
  files, threaded through the drain and send-now overrides, and
  restored by the queued row's Edit message
- Key an early-aborted FIRST turn's run-end signal to NEW_CONVO
  (resolveRunEndTarget) so queued follow-ups stay visible on the
  restored new-chat composer instead of parking under an optimistic
  stream id the user never sees again

* 🧿 fix: Round-15 Gap Coverage + Consolidated Sweep (Share Leak, Abort Ids, Chip Hygiene)

- Run the resume steer-gap check for every still-active job: an empty
  snapshot no longer skips the re-peek, and synthesis now keys on the
  FRESH content view so an applied-in-gap steer that was never
  snapshotted still re-surfaces (over-emission is benign — applied-id
  dedupe, index-stable parts)
- Thread queued context through steer degradation: sendQueuedNow passes
  the item's quotes/skills into submitSteer, and every fallback
  (requeue or settled send) restores them instead of dropping to
  text+files
- Stop shared links from leaking steer attachment refs: the share
  snapshot now walks content — files-excluded shares strip steer-part
  files entirely; files-included shares sanitize and share-route them
  like top-level files (copy-on-write, non-steer content by reference)
- Seed pending-steer chips unconditionally on load/return so a steer
  applied while away cannot linger as a stale chip beside its part
- Use the abort response's resolved job id: chips/drain-signal land
  where the user actually is (NEW_CONVO for a new-held first turn,
  consistent with resolveRunEndTarget) while the parked-copy claim hits
  the resolved id instead of a no-op /chat/status/new
- Open steered documents like normal message files (FilePreviewDialog)
- Cap the applied-steer id set on the live path via a shared helper;
  kept surviving run end deliberately (late-ACK race depends on it) and
  fixed the atom comment that claimed otherwise

* 💡 fix: Un-light Steer Ribs When Their Node Is Replaced

Two stacked gaps kept a steer rib lit after scrolling away: the
pending→applied swap replaces the DOM node under the same id, which
produces no IntersectionObserver exit and — because the entry list
dedupes on (id, preview) — no entries change either, so the observer
kept watching a detached node; and the rail's mutation filter only
reacted to .message-render nodes, so steer-node swaps and removals
never triggered a refresh at all.

- reconcileObservedElements re-points the observer at replaced nodes
  from the mutation-driven refresh regardless of entries identity,
  dropping stale visibility until the fresh node reports (the observer
  fires its initial intersection immediately, so a truly visible part
  re-lights within a frame)
- The mutation filter now recognizes steer-render nodes alongside
  message rows

* 🪪 fix: Round-16 Recovery Owner Fields + Context Stickiness + Share Labels

- Park resumed-run leftovers with the manager facade's metadata owner
  fields: a bare job.userId is undefined on that shape, which made
  every parked payload from a resumed HITL run unclaimable
- Keep a queued item's quotes/skills sticky through a successful steer
  ACK: the pending chip carries them (client-only), reseeds preserve
  them across reconnects, and every terminal conversion — local or
  server-list, merged by steerId — restores them onto the queued item
- Convert resumeState.pendingSteers on the inactive status branch
  (deduped against unrecoveredSteers) so steers observed in the
  expired-pause-before-sweeper window convert instead of vanishing
  until a later reload
- Label shared steer parts share-safely via the existing ShareContext:
  a viewer's own name no longer appears on the sharer's steered
  messages

* ✂️ fix: Carry Steer Context Through the Failed-Chip Edit Action

Retry and convert-to-queue already preserve a failed steer's carried
quotes/skills; Edit message dropped them on the way back to the
composer. It now restores them through the same context path.

🙋 feat: ask_user_question - agent-initiated questions with durable pause/resume (#14139)
* feat: ask_user_question tool — agent-initiated questions with durable pause/resume

The HITL runtime merged in #13942/#14024/#14025/#14123 already ships the full
ask_user_question lifecycle (payload-agnostic handleRunInterrupt, resume
validation via mapAskUserAnswer, reconnect rehydration, and the client question
card) — but nothing ever raised the interrupt. This adds the producer:

- packages/api/agents/hitl/askUserQuestionTool.ts: LLM-callable tool whose func
  calls the SDK askUserQuestion() helper (LangGraph interrupt() from the tool
  body); zod schema with length caps mirroring AskUserQuestionRequest, plus a
  JSON-schema twin for the schema-only registry
- Registration: agentToolDefinitions, manifest.json (Tools dialog, admin
  filteredTools/includedTools kill switch), basicToolInstances, handleTools
  constructor branch
- run.ts gating: checkpointer now attaches for hitlCapable runs whose agents
  carry the ask tool even with the tool-approval policy disabled (the interrupt
  needs only durability, not humanInTheLoop/hooks); the tool is stripped
  fail-closed from non-HITL callers (OpenAI-compat/Responses) and subagent
  child configs; excluded from eager event execution (interrupts must be
  raised inside the Pregel task frame)
- resume.js: 16k length cap on the answer wire field
- e2e (real Run + FakeChatModel + LazyMongoSaver + supertest resume): tool-body
  interrupt pauses durably with NO approval policy, answer round-trips as the
  ToolMessage content, tool body re-runs once on resume, sequential questions
  re-pause

* fix: adversarial-review findings — in-graph execution, orphan prunes, endpoint scoping, real kill switch

Pre-PR multi-agent review confirmed 5 defects in the initial commit; all fixed:

1. CRITICAL — the tool never paused on the real agents endpoint: production
   loads tools definitions-only, flipping the SDK ToolNode to event-driven
   dispatch, and the host ON_TOOL_EXECUTE handler runs outside the Pregel task
   frame (under runOutsideTracing), where interrupt() throws and becomes an
   error ToolMessage. Reworked: the ask tool never rides toolDefinitions/
   toolRegistry — on HITL-capable top-level agents a real instance is supplied
   via AgentInputs.graphTools (agents#289, requires @librechat/agents > 3.2.57),
   the SDK's in-graph direct-tool seam; new production-shape e2e pins the
   event-driven mode end to end.
2. CRITICAL — ask-only runs left orphaned interrupted checkpoints (silent
   context duplication on every later turn): both orphan prunes were gated on
   toolApproval.enabled. The pre-turn prune now also fires for ask-capable
   agents (exported agentRequestsAskUserQuestion), and the abort-route prune
   fires when the aborted job carries a pendingAction.
3. MAJOR — self-spawned subagents bypassed the strip (self config resolves from
   the parent's _sourceInputs): fixed SDK-side (buildChildInputs clears
   graphTools) and the tool is now never present on child surfaces host-side.
4. MINOR — the manifest entry leaked into the Assistants tools dialog and the
   legacy plugins endpoint, where tools execute with no run to pause: new
   agentsOnly manifest flag, scoped out of both listings.
5. MINOR — filteredTools/includedTools only hid the tool from the dialog:
   now enforced at run build (strip + no checkpointer), making the admin
   filter a real kill switch for already-saved agents.

* chore: update @librechat/agents dependency to version 3.2.58 in package-lock.json and package.json files

* fix: reject agents-only tools at assistant create/update (Codex round 1)

The tools-dialog scoping keeps ask_user_question out of the assistants
LISTING, but the v1/v2 create/update handlers resolve arbitrary posted tool
strings from the shared getCachedTools map — a REST client or stale saved
payload could still attach it, and the assistants runtime executes tools with
no run to pause, so every call would error. New isAgentsOnlyTool(tool)
(manifest-driven, handles string and function-object shapes) drops such tools
with a warn at all four resolution sites (v1+v2, create+update).

* fix: offset resumed-run content indices past the pre-pause seed

A resumed run rebuilds the graph from the checkpoint, and the fresh graph
numbers content indices from its own empty contentData — starting at 0. The
resume path seeds the (also fresh) content aggregator with the pre-pause
parts at exactly those indices, so the resumed model turn collided with the
seed: type-matching parts silently MERGED (post-resume text appended into a
pre-pause text block), and type-mismatching parts (a reasoning/think part at
index 0 — any Anthropic reasoning agent) dropped EVERY delta with 'Content
type mismatch', losing the entire post-resume output from the live stream
and the saved message.

Latent since #13942 — tool-approval resumes corrupt content the same way
(probe-verified); it surfaced now because ask_user_question makes pausing a
first-class flow and reasoning models make the loss total.

- createContentIndexOffsetHandlers(handlers, offset): wraps ON_RUN_STEP
  (the single point where a content index enters the pipeline — deltas
  resolve through the aggregator's stepMap) and ON_AGENT_UPDATE's inline
  index; every other handler passes through by reference. Probe-validated:
  resumed output now lands as a new part after the paused tool call.
- resumeCompletion wires it with offset = seedContent.length.
- logToolError: a GraphInterrupt unwinding out of a tool body is the HITL
  pause working as designed — no longer logged as a Tool Error.

* fix: unblock live streaming of the resumed segment after an answer

With resume indices now ABSOLUTE (server continues after the pre-pause
parts), the synthetic ask-user-question card was squatting on exactly the
index the resumed segment streams into: applyAskUserQuestion appends the
card at the end of the message content, so on the answering device every
incoming part at that index was blocked and nothing rendered between the
answer submission and the finalize replacing the message.

removeAskUserQuestionPart(message, actionId) strips the pause-scoped card
on successful answer submission (useResumeSubmit onSuccess) — the durable
record of the Q&A is the ask_user_question tool call itself. Pure helper +
specs; same-reference no-op when nothing matches.

* fix: displace the synthetic question card in the streaming content writer

The store-level strip on answer submit wasn't enough: the SSE step handler
keeps its own in-flight copy of the streaming message, so on the answering
device the synthetic ask-user-question card still occupied the ABSOLUTE index
the resumed segment streams into — every delta warned 'Content type mismatch'
(existing ask_user_question vs incoming text) and nothing rendered between the
pending_action and finalize.

Displace the card inside updateContent when any real part claims its slot —
the same displacement pattern as the OAuth prompt part directly above it.
Covers the streaming handler's own copy, reconnecting tabs, and other devices;
once real content streams, the pause is over by definition. Spec drives a
runStep + text delta into the card's index and pins: no mismatch warn, card
gone, text rendered.

* feat: dedicated UI + durable data for completed ask_user_question calls

The completed ask call rendered as a generic tool card labeled 'Cancelled'
with raw (and empty) JSON args. Two layers fixed:

Data: the saved tool_call part had args:'' and no output — streamed arg
chunks carry no tool name so the aggregator drops them (normal tools recover
via the completion event, which never fires for a tool that interrupts
mid-execution and resumes on a rebuilt run with no step id). The resume
controller now stamps the paused ask part with the pendingAction's
authoritative question as args and the user's answer as output
(attachAskUserQuestionAnswer — pure, targets the newest unanswered ask part,
so sequential questions each keep their own answer).

UI: Part.tsx routes ask_user_question tool calls to AskUserQuestionCall — a
compact Q&A record ('Asked a question' header, question, description, 'You
answered: <label>' preferring the picked option's label, or 'No answer was
given' for an abandoned pause) instead of the generic card. New i18n keys;
parseAskUserQuestionArgs degrades to null on malformed model args.

* fix: single question UI per pause + immediate answer display

Two live-turn issues with the new durable Q&A card:

1. Duplicate question on ask: during a live pause the message carries BOTH the
   ask tool_call part (now rendered by AskUserQuestionCall, showing a
   misleading 'No answer was given' while paused) and the synthetic
   interactive card. The durable card now defers while the turn is live and
   unanswered (isSubmitting) — the interactive card owns the question UI until
   it's answered; an abandoned pause still shows its no-answer state once the
   turn settles.

2. 'No answer was given' after answering: the server stamps the answer onto
   the part at resume seed, but the client only received that at finalize. No
   stream emission needed — the client knows the answer it just submitted:
   resolveAskUserQuestionPart (replacing the plain strip on submit success)
   removes the synthetic card AND stamps output/progress onto the newest
   unanswered ask tool_call, seeding args from the synthetic part's question
   when the streamed args were lost — mirroring the server-side
   attachAskUserQuestionAnswer, so the Q&A record shows the answer the moment
   the user submits.

* fix: keep the Q&A record visible while the resumed segment streams

The optimistic output stamp lives in the message store, but the SSE step
handler evolves its own cached copy of the streaming message (created at turn
start) — the first resumed event overwrites the store with that copy, wiping
the stamp, so the Q&A card blinked out during streaming and only returned at
finalize.

Render-layer fallback instead of fighting the handler's copy: submitted
answers are recorded by ask tool_call id when resolveAskUserQuestionPart
stamps the part, and AskUserQuestionCall reads the recorded answer whenever
the part's own output is missing — the record survives any message-copy churn
until finalize delivers the server-stamped part.

* feat: present Ask User as a native builtin in the tools dialog

It ships with the app and pauses the run like a first-class feature, so it
belongs with the builtins (Run Code, Web Search, Memory, ...) rather than in
the third-party plugin list — while its mechanics stay exactly a plugin's:

- BuiltinId += 'ask_user_question' (documented exception: a native TOOL, not
  a capability; selection reads agent.tools, the toggle emits tool-add/remove
  patches instead of a capability field)
- buildCatalog surfaces it as a builtin gated on the same signals as before
  (tools capability on + the server lists the plugin, i.e. not admin-filtered)
  and skips it in the plugin loop so it never double-lists
- On-theme icon: lucide MessageCircleQuestion in a teal chip via the builtin
  icon map, matching the other native entries; the bespoke purple SVG and the
  manifest icon field are gone
- i18n'd name/description keys like the other builtins

* feat: composer popover for answering questions (mentions-style)

Answering moves to the composer, matching the existing mentions/prompts
popover pattern: while an ask_user_question pause is live, a popover anchors
above the textarea with the question as its header, numbered option rows
(hover/click, or ↑/↓ + Enter from the empty composer), and an × to dismiss.
The main textarea doubles as the free-form answer — its placeholder flips to
'Something else...' and form submit routes the text to the paused run as the
answer instead of starting a new turn. Dismissing (× or Escape) restores
normal sends; the inline transcript surfaces stay as before (interactive card
while paused, durable Q&A record after) so the question remains visible in
history.

- findLiveAskUserQuestion (pure, spec'd): newest unanswered synthetic part
  across the conversation IS the popover signal — applied on
  on_pending_action, stripped on answer submit, so visibility tracks the
  pause lifecycle with no extra state
- useLiveAskUserQuestion hook shared by the popover and ChatForm; dismissals
  in a recoil atom so both react
- popover only mounts on the primary composer (index 0), mirroring QuoteButton

* feat: number-key selection + return glyph in the question popover

Pressing 1-9 in the empty composer picks the matching option directly,
mirroring the numbered row chips; the highlighted row shows a return-key
glyph as the Enter affordance. Same empty-composer guard as the arrow keys —
typing a free-form answer is never intercepted.

* refactor: first-class composer answer mode (useAskAnswerMode)

Replaces the bolted-on integration (inline onSubmit interception + raw
capture-phase keydown listeners on the textarea ref) with a single hook that
owns the whole answer mode: live-question derivation, dismissal + highlighted
option (shared recoil state), option selection, free-form submit routing
(submitText returns whether it consumed the submission), and keyboard
handling (handleKeyDown returns whether it consumed the key, composed ahead
of the textarea's normal handler — no more addEventListener).

The popover is now pure rendering off the hook; ChatForm wires placeholder,
onKeyDown, and onSubmit through the same instance. Deliberately scoped to the
composer rather than useSubmitMessage: starters/prompt-commands keep new-turn
semantics (and the existing job-replacement behavior while paused).

* fix: Codex round 2 — inline answer input, approval exemption, pause-time args

F1 (composer submit unreachable while paused — isSubmitting keeps Stop shown
and useTextarea eats Enter): redesigned around it, borrowing Claude Code's
AskUserQuestion semantics. The popover now owns free-form input via an inline
'Other' row (numbered last, 'Something else…'), with select-then-confirm rows
(click/arrows/digits highlight; Submit ↵, Enter, or double-click fires; Skip
dismisses). The composer returns to being a plain composer — no placeholder
swap, no submit interception; Stop keeps meaning stop.

F2: ask_user_question is exempt from the tool-approval prompt unless the
admin explicitly lists it (allow/ask/deny all win) — approving the right to
ask a question was a pure double pause; the tool is side-effect-free.

F3: the question is stamped onto the paused ask tool_call's args at PAUSE
time (attachAskUserQuestionArgs in handleRunInterrupt), so abandoned/expired/
stopped turns persist with the question intact and the record card can render
it — previously only the answer-resume path stamped args.

* fix: fold model-supplied 'Other' options into the inline free-form row

The model can generate its own catch-all option ('Other (type your own)',
value 'other'), duplicating the popover's built-in free-form row — two
other-ish rows, one pickable as a literal answer. Two layers:

- Tool description now tells the model NOT to include catch-all options (the
  answer UI always offers free-form input on its own)
- splitOtherOption (pure, spec'd) folds a catch-all option that arrives
  anyway out of the choice rows and uses its label as the inline input's
  placeholder — conservative match (value 'other', or a label reading as a
  free-form invitation), no false positives on real choices

* fix: single question surface + clean free-form-only popover

Two live-pause confusions: (1) the inline transcript card and the composer
popover both rendered — the card now defers while the popover is up for its
action, returning as the fallback surface when the user dismisses the popover
(and in contexts without a ChatContext, where the popover can't exist);
(2) an options-less question showed a pointless numbered '1 Something else…'
row — free-form-only questions now render the inline input alone, with the
'Type your answer…' placeholder (a folded model 'Other' label still wins).

* feat: the composer is the free-form answer box (like the main chat input)

While a question pause is live, the main chat textarea composes the free-form
answer — placeholder swaps to 'Something else…' (or a folded model 'Other'
label), Enter with text submits the answer through answer-mode key handling
(composed BEFORE useTextarea's submitting-lock, so the lock can't swallow it),
and the Stop button swaps to Send (enabled despite isSubmitting) per the
select-then-confirm design. The popover slims to the question header, numbered
option rows, and Skip/Submit — its inline input is gone since the composer
owns free-form now. Dismissing the popover restores normal composer semantics
(Stop button, normal sends).

* fix: Codex round 3 + real Skip semantics

- Skip now ANSWERS instead of hiding UI (danny): it resumes the run with a
  decline notice ('The user chose not to answer this question.') so the model
  moves on — a client-side dismiss left the run paused until expiry, a hung
  turn. × / Escape remain pure dismiss (switch to the inline card surface).
- P1 (resumed approval tool indices): resumed tool_calls steps whose
  tool_call id matches a seeded UNRESOLVED part now rebind to that seeded
  slot instead of offsetting — the original part resolves in place (output
  attaches) and no duplicate appears; message steps keep the offset, so the
  text-loss fix stands. createContentIndexOffsetHandlers now takes the seed
  array; resolved seeded calls are not rebind targets.
- P2 (stale selection across questions): selection state resets when the
  live actionId changes; the vestigial inline-Other state ('other' selection
  + text atom) is gone — the composer owns free-form.
- P2 (Redis abort path loses the args stamp): the abort route re-stamps the
  question onto the ask tool_call in the reconstructed abort content, so a
  Stop-abandoned question persists with its question intact.
- P2 (malformed args crash): parseAskUserQuestionArgs normalizes untrusted
  shapes (options: {} / non-string entries) instead of throwing in render.

* feat: free-form hint in the question popover footer

Left-aligned in the footer row (opposite Skip/Submit): 'Or type your answer
below' — points open-ended answering at the composer, whose placeholder
already reads 'Something else…'.

* feat: preserve composer drafts across the answer-mode swap

The answer phase gets its own draft key (ask-answer:<actionId>), passed as a
draftId override into useAutoSave — the key change itself drives the existing
save/restore machinery, so the conversation draft (or mid-run PENDING draft)
is stashed when a question pause takes the composer and restored once the
user answers, skips, or dismisses. Ask keys are exempt from the PENDING
migration branch, which would otherwise move-and-delete the stashed draft. A
half-typed answer survives reload/navigation while its question stays live.
Answer submission (option pick, free-form, skip) resets the composer via a
new non-throwing useOptionalChatFormContext, so the swap-back restores into
an empty box even outside ChatView-less render contexts (Share/search).

* fix: rebind resumed steps for ALL seeded tool call ids

The resume controller pre-stamps the user's answer onto the seeded
ask_user_question part, so the unresolved-only rebind predicate treated
it as settled and shifted the tool's re-run step to a fresh offset slot,
leaving a duplicate ask record in streamed/saved content. Tool call ids
are provider-minted per call: a resumed step bearing a seeded id can
only be the interrupted batch re-executing, so rebinding every seeded
id is always correct.

* feat: popover UX round 4 — clickable hint, collapse, click-submit, multiSelect

- Footer hint is a button that focuses the composer; reads 'Type your answer
  below' (no 'Or') when the question has no options.
- Collapse (chevron) hides the popover WITHOUT closing the pause: answer mode
  stays live (placeholder, Enter routing, draft key), the chat card renders
  the question with a ChevronUp affordance to re-expand. x remains dismiss.
- Single-select options submit on a single click; the Submit button renders
  only for multi-select.
- multiSelect end-to-end: tool zod schema + JSON definition twin, wire type,
  client parse, popover check-chips, card toggles, record-card label mapping;
  answer = option values joined ', '; composer Enter and the multi Submit
  button both fold free-form text in with the checked values.
- Hardening from adversarial review: in-flight status guard on every submit
  path (no duplicate resumes on double-click), popover locks while
  submitting, collapsed mode disarms invisible digit/arrow steering, the
  card shares the hook's checked state while the pause is live, the card
  folds catch-all 'Other' options, record mapping is all-or-nothing to avoid
  phantom labels, composer resets only when its text was consumed or the
  draft machinery will restore the stash.

* feat: ask_user_question in model specs and ephemeral agents

A librechat.yaml modelSpec can now equip the tool the same way it equips
webSearch/executeCode/fileSearch/memory:

  modelSpecs:
    list:
      - name: my-spec
        askUserQuestion: true

loadEphemeralAgent pushes the tool name when the spec flag (or the
ephemeralAgent request flag, wired for parity) is set; everything downstream
is the existing persisted-agent machinery — createRun's hitlCapable gating,
graphTools injection, checkpointer attach, subagent strip, and the admin
filteredTools/includedTools kill switch all apply unchanged.

* feat: tense-aware Q&A record label (Asking / Asked)

Shorten the record card header per feedback: 'Asking' while the question is
still unanswered (abandoned/awaiting), 'Asked' once answered — replacing the
single 'Asked a question' label.

* fix: Codex round 4 — added-agent ask parity + preserve answer on failed resume

F1 (added.ts): mirror loadEphemeralAgent's ask_user_question branch in the
added-agent loader so a model spec's askUserQuestion flag (or the ephemeral
request flag) equips added top-level agents too, matching execute_code /
web_search / memory. Two load.spec cases added.

F3 (composer): submitAskAnswer now takes an onSuccess callback and
useAskAnswerMode defers clearing the selection/composer until the resume is
accepted. A failed resume (16k answer-cap 400, expired action, network error)
leaves status re-answerable, so wiping the composer up front lost the user's
only copy of a free-form answer; now it survives for trim/retry.

(F2 — a claimed Tools-capability bypass — was verified NOT reproducible:
agentRequestsAskUserQuestion matches only loaded instances/toolDefinitions/
toolRegistry, all capability-filtered; a raw tools string has no .name and
never triggers the install. Replied on-thread with the probe evidence.)

* fix: Codex round 5 — expired question exits answer mode so its message shows

An expired question (e.g. resume returns the stale-action 409) previously left
the popover open with locked controls and no explanation, because the chat
card — which carries the only 'this action expired' message — was suppressed
by the popover-open guard. Treat 'expired' as no longer active: the popover
closes, the composer reverts to normal, and the card becomes the sole surface
and renders the expired message. 'error' stays active (retryable).

* feat: group ask_user_question calls as their own category

A homogeneous group of ask_user_question tool calls now reads 'Asked N
questions' (present tense 'Asking N questions' while the turn streams) with a
question glyph and no raw-name suffix — mirroring the subagent 'Ran N agents'
category treatment, instead of 'Used N tools — ask_user_question'. Mixed
groups keep 'Used N tools' but humanize the suffix to 'Question' and show a
question icon for the ask entries (TOOL_FRIENDLY_NAME_KEYS + ToolIcon map).
A group only forms at count >= 2, so the plural is always grammatical.
Three ToolCallGroup.test cases cover homogeneous label/icon/suffix, present
tense while streaming, and the mixed-group fallback.

* fix: Codex round 6 — composer submit lock + abort stamp before emit

F7 (composer status lock): the ask submit status lived on ApprovalContext,
a React context mounted only around message content (ContentParts). The
PRIMARY answer surface — the composer in ChatForm — renders outside it, so
useApprovalContext returned the inert FALLBACK: status was always 'idle',
setStatus a no-op. The in-flight double-submit guard (round 4) and the
expired-exits-answer-mode fix (round 5) therefore never engaged for the
composer. Move ask submit status to a global Recoil atom (useAskSubmitStatus)
read/written by the composer, the popover, and the card alike, so a fast
double-click/Enter is actually blocked and expired/error surfaces on every
surface. Tool-approval status stays on the context (unchanged).

F5 (abort stamp before emit): the abort route re-stamped a paused
ask_user_question's args AFTER GenerationJobManager.abortJob had already
emitted the final SSE from the unstamped content, so a Redis/cross-replica
Stop left the live client showing an empty question until reload. abortJob
now takes an optional transformAbortContent applied to the persistable
content BEFORE the final event is built (and returned), so the live client
and the saved message agree. New abort.spec case + updated call assertions.

* feat: gate ask_user_question behind its own agent capability

Add a first-class AgentCapabilities.ask_user_question (in defaultAgentCapabilities,
on by default) so admins can enable/disable questions independently via
endpoints.agents.capabilities, exactly like execute_code / web_search — not
lumped under the generic tools capability.

- ToolService: both filteredTools predicates (definitions-only and instance
  loaders) gate ask_user_question on checkCapability(ask_user_question) before
  the generic tools fallthrough. When off, the tool is dropped from
  toolDefinitions/toolRegistry, so run.ts's agentRequestsAskUserQuestion (which
  keys on the loaded surface) declines to install it and attach a checkpointer —
  the capability is enforced end-to-end at the loader, no run.ts change needed.
- Tools dialog catalog: surface the ask builtin under its own capability rather
  than the generic tools one, so the UI matches the backend gate.
- Tests: ToolService capability on/off filtering + defaults membership; catalog
  builtin visibility keyed on the dedicated capability.

* style: sort imports in ToolCallGroup.test (CI import-order gate)

* fix: Codex round 7 — surface ask-answer errors in the open popover

A failed answer submission (16k reject, network error) sets the ask status to
'error', which — unlike 'expired' — deliberately keeps the question active and
retryable. But the chat card that renders the error message is suppressed while
the popover is open, so a composer/popover answer failed silently. Expose an
'errored' flag from useAskAnswerMode and render a warning line
(com_ui_ask_answer_error) in the popover, so the user gets feedback and retry
guidance without having to collapse/dismiss. It clears automatically on retry
(status flips to 'submitting').

* fix: Codex round 8 — respect IME composition before submitting answers

handleComposerKeyDown runs before useTextarea's composition guard, so with a
CJK/IME keyboard the Enter that commits an in-progress composition was being
intercepted and submitting the partial answer (and the composition buffer can
leave value empty mid-compose, mis-triggering digit/arrow steering too). Bail
at the top when composing — nativeEvent.isComposing, or key==='Process' /
keyCode===229 for Safari's inconsistent reporting — mirroring the existing
composer guard so the character commits normally.

* chore: update `@librechat/agents` to v3.2.60

* 🔧 chore: Update @opentelemetry/core to version 2.9.0 and clean up package-lock.json

* feat: digit shortcuts select options when the popover has focus

Previously a number key (1..N) only selected an option from the empty
composer (handleComposerKeyDown on the textarea) — if focus moved into the
popover (a row/Skip/Submit button clicked or tabbed to), the number keys went
dead. Add handlePopoverKeyDown, wired to the popover container's onKeyDown so
it catches digits bubbling from the focused control: a digit activates its
option exactly like a click (single-select submits, multi toggles). No
highlight/Enter dance on this path — the options are buttons whose action is
the click, and intercepting Enter would fight the focused button. Gated on
active && !locked so it no-ops while a submit is in flight.

* chore: update @librechat/agents to version 3.2.61 and @opentelemetry packages to latest versions

🤐 fix: Exclude Provider Secrets from HITL Pending Actions (#14136)
* 🤐 fix: Exclude Provider Secrets from HITL Pending Actions

Sanitize resolved model parameters before persisting them in the pending
action's resumeContext, and strip resumeContext/requestFingerprint from
every client-facing copy (SSE emit, reconnect gap-fill, resume state,
status route). The full record stays server-side for resume replay.

* 🤐 fix: Treat Header-Carrier Keys as Sensitive Wholesale

Google llmConfig places the Authorization header in customHeaders, and
header names like Ocp-Apim-Subscription-Key defeat name heuristics.
Match 'header' as a key fragment so every header-carrier object is
dropped rather than relying on exact carrier names.

* 🤐 fix: Strip Preconfigured Client Instances from Resume Params

Bedrock stores a BedrockRuntimeClient on llmConfig.client when PROXY or
a bearer token is configured; replaying it would also fold a mangled
client object into additionalModelRequestFields on resume.

* chore: add @langchain/langgraph-checkpoint-mongodb for HITL durable resume

* feat: HITL tool approval runtime — backend (Slice B)

- endpoints.agents.checkpointer config + durable Mongo checkpointer (seam over the app
  connection; SDK MemorySaver fallback) with a TTL index + deleteThread pruning
- HITL run wiring (PreToolUse policy hook + humanInTheLoop) attached in createRun, fully
  inert when toolApproval.enabled is off
- interrupt gate (pause job -> requires_action + emit on_pending_action) and a resume
  route that rebuilds the run from the durable checkpoint and run.resume()s it
- atomic single-winner resolve; agent-consistency guard; expireStaleApprovals terminal
  event; checkpoint pruned on every non-paused completion (thread_id == conversationId)

* feat: HITL tool approval UI — frontend (Slice B)

approve/reject/edit/respond + ask-user controls in the tool card (OAuth-button precedent),
batch-aware single submit, live + reconnect (resumeState.pendingAction) wiring, and resume
mutations posting to /agents/chat/resume.

* fix(hitl): decouple ApprovalProvider from chat context

ApprovalProvider is now pure state (safe to mount in provider-less / shared / test
renders); the context-dependent submit moved to a useResumeSubmit hook the cards call.
Part imports getAskUserQuestionPart from ~/utils/approval directly so suites that
partial-mock ~/utils render Part without throwing.

* fix(hitl): address Codex review — backend

- P1: enforce per-tool allowed_decisions on resume (reject a crafted decision the
  policy disallows) via findDisallowedDecisions
- prune the durable checkpoint on user-abort of a paused run, and before a fresh
  HITL turn, so a new turn cannot rehydrate an expired/aborted interrupt (thread_id
  is the stable conversationId)
- persist + use isTemporary and the original parentMessageId on resume (temporary
  chats stay temporary; initializeAgent scopes thread files off the right parent)
- generate a deferred first-turn title BEFORE completeJob so its event reaches the
  client and the final event carries the real title
- moderateText: skip when there is no text (tool-approval resume) and moderate the
  ask-user answer, instead of denying on an empty input

* fix(hitl): address Codex review — frontend

- render ToolApproval for ANY paused agent tool card (bash/code/file/etc.), not just
  the generic ToolCall, by wrapping the tool-card branch in Part (moved the rendering
  out of ToolCall)
- findPendingActionMessageIndex only matches an assistant message, never the user
  message (the underscore-strip could target the user bubble before the assistant
  placeholder exists)

* fix(hitl): address Codex re-review

- title eligibility checks the user message’s parent (first turn), not the response’s
  parent — the previous check could never be true and skipped title generation
- use client.buildResponseMetadata() for the resumed message so contextUsage /
  thoughtSignatures survive (the abort-only helper dropped them)
- moderate decisions[].responseText (the respond action’s user text)
- give /chat/abort req.config (configMiddleware) so the HITL checkpoint prune on abort
  actually runs
- read resume state BEFORE setContentParts so the in-memory store does not lose the
  pre-pause seed content
- count resumes against LIMIT_CONCURRENT_MESSAGES (increment/decrement) so paused-then-
  resumed turns cannot bypass the limit
- require actionId on resume so a body without it cannot resolve the current action

* fix(hitl): address Codex re-review (round 3) — resume fidelity

Bring the lean resume path to parity with sendMessage for things it bypassed:
- carry userMCPAuthMap into the rebuilt run so approved MCP tools keep the user's creds
- seed initialSessions (buildInitialToolSessions) so approved code/file/skill tools have
  the pre-pause uploaded-file context (esp. cross-replica / after restart)
- await client.artifactPromises and persist them as response attachments (else tool
  artifacts created after the pause vanish on reload / for late subscribers)
- merge metadata: cumulative usage (+ summary marker) from the job, contextUsage /
  thoughtSignatures from the client — fixes the round-2 regression that underreported
  post-resume cost

* fix(hitl): address Codex re-review (round 4) — resume hardening

- resume: require an EXACT paused agent_id match (reject omitted/ephemeral
  agent_id, not just a different one) and reject an endpoint mismatch, so a
  request can't rebuild the claimed checkpoint on a different graph
- moderateText: also moderate a tool-approval decision's reject `reason` and
  stringified `editedArguments`, not just `responseText`
- request: re-mark the paused response `unfinished:true` after BaseClient saves
  it as completed, so an expired / never-resumed approval doesn't leave a
  "finished" response in history; the resume path overwrites it on success

* test(hitl): route-level integration test for the resume controller

Adds api/server/controllers/agents/__tests__/resume.spec.js, a supertest
integration test that drives the real ResumeAgentController over the full
pause -> approve -> resume -> finalize lifecycle with the SDK run, durable
checkpointer, Mongo, and concurrency cache mocked. The pure decision/liveness
helpers run for real via requireActual, so the guard ladder is exercised end to
end rather than stubbed.

25 cases covering:
- the authorization / staleness / agent-and-endpoint / actionId guard ladder
- tool_approval validation (undecided tool call, policy-disallowed decision)
- ask_user_question answer requirement
- the concurrency gate (429) and the atomic single-winner claim (409)
- the happy path: ACK, run reconstruction, decision->SDK mapping, finalize
  (save the now-finished response, emit done, complete job, prune checkpoint)
- first-turn title generation before stream completion
- re-pause (no double finalize), abort-during-resume (no double finalize),
  and the resume-failure terminal path (emitError + completeJob + prune)

* test(hitl): strengthen resume coverage + add approval util tests

Acts on a self-audit of the new resume integration test.

resume.spec.js (25 -> 32 cases):
- replace the tautological emitDone assertion (it only checked the hardcoded
  `final: true`) with a structural check of the finalEvent payload —
  responseMessage content/id/unfinished, requestMessage identity, title
- cover the previously-unwalked finalize branches: tool-artifact attachments
  (null-filtered), the aggregatedContent fallback when live content is empty,
  and client response-metadata attachment
- add guard cases: unsupported pending-action type (400) and the
  pre-multi-tenancy null-tenantId pass-through (must not 403)
- add error-path cases: first-turn title generation throwing must still
  finalize, and a completeJob failure during a resume error must force a
  terminal job state via the last-resort updateJob

client/src/utils/approval.spec.ts (new, 15 cases):
- applyPendingAction tool_approval: join by tool_call_id not position,
  skip completed calls, default allowed_decisions to [], referential
  stability when nothing changes
- applyPendingAction ask_user_question: append, idempotent replace on replay,
  non-array content coercion
- getAskUserQuestionPart type guard; findPendingActionMessageIndex
  assistant-only resolution (never resolves to the user bubble)

* fix(hitl): address Codex re-review (round 5)

Five findings verified against the code before fixing:

- resume: require an EXACT endpoint match (like agent_id) — a resume that OMITS
  endpoint must not fall through, since the shared chat middleware treats a
  missing/non-agents endpoint as the ephemeral agent and could rebuild the
  claimed checkpoint on a different graph
- resume: filter malformed content parts before saving the finished response,
  matching the normal AgentClient path (a resumed turn could otherwise persist
  an empty/invalid tool_call part that breaks reload/rendering)
- resume: accumulate tool artifacts across pause segments — persist them on
  re-pause and MERGE (not overwrite) at finalize, so artifacts produced before
  a second approval pause aren't dropped by the next rebuilt client
- approval (client): findPendingActionMessageIndex returns -1 when a provided
  responseMessageId isn't found, so the caller retries instead of attaching the
  prompt/approval to a prior assistant reply; fall back to the last assistant
  only when no responseMessageId is given
- RedisJobStore: make appendChunk extend-only (XADD + EXPIRE-if-shorter via a
  single eval) so the on_pending_action chunk emitted after a pause can't reset
  the chunk-stream TTL back to the running window and evict pre-pause content
  before the approval is resolved

Tests: +endpoint-omitted/unsupported-type/malformed-filter/attachment-merge/
re-pause-persist cases in resume.spec.js (36); ask-retry -1 semantics in
approval.spec.ts (16); extend-only TTL assertion in the RedisJobStore Redis
integration spec.

* test(hitl): mongodb-memory-server integration test for the checkpointer seam

The checkpointer unit spec covers config/selection with no DB connection; this
exercises the durable Mongo seam against a real (in-memory) MongoDB — the part
correctness actually depends on:

- getAgentCheckpointer builds a real MongoDBSaver when Mongo is connected and
  setup() creates the TTL index (expireAfterSeconds) on the checkpoint collection
- memory type returns undefined (SDK MemorySaver fallback) even when connected
- saver is memoized per resolved config
- deleteAgentCheckpoint prunes a thread's persisted checkpoint (the cross-turn
  isolation guarantee: turn N+1 on the same conversationId can't rehydrate it)
- pruning is thread-scoped — deleting one conversation leaves others intact
- undefined threadId is a no-op

* fix(hitl): address Codex re-review (round 6)

Four findings verified against the code before fixing:

- messageFilterPii: scan the resume payload's user-authored text (ask-user
  `answer`, and a tool-approval decision's `respond` text, `reject` reason, and
  edited tool arguments) — the shared /resume route ran through the PII filter
  but it only inspected req.body.text, so a blocked token rode the resume
  payload back into the model/tool (mirrors the earlier moderateText fix)
- resume: re-prime skill files invoked in the pre-pause segment before rebuilding
  the run, so an approved code/file-backed tool keeps the injected skill-file
  session refs instead of running without them (mirrors the normal path's
  primeInvokedSkills; the pre-pause content stands in for the message payload)
- hitl: pin the graph identity. Persist a fingerprint of the graph-determining
  request fields (endpoint, agent_id, model, spec, ephemeralAgent — normalized)
  on the pending action at pause, and reject a resume whose recomputed
  fingerprint differs. This closes the ephemeral-agent gap, where agent_id is
  undefined so the id guard can't tell two ephemeral configs apart
- resume: reject incomplete edit/respond decisions (findIncompleteDecisions) —
  an `edit` without an object editedArguments or a `respond` without non-empty
  responseText is 400'd before mapping, rather than defaulting to {} / '' and
  resuming with behavior the user never approved

Tests: incomplete-decision + fingerprint match/mismatch cases in resume.spec.js
(41); findIncompleteDecisions + computeAgentRequestFingerprint unit tests; and
resume-field PII cases in messageFilterPii.spec.ts.

* fix(hitl): address Codex re-review (round 7)

Four findings verified against the code before fixing:

- RedisJobStore: clear `agent_id` on createJob (add it to staleHitlFields). The
  job hash is keyed by conversationId and reused across turns; updateMetadata
  only writes agent_id when truthy, so a conversation that switched from a saved
  agent to an ephemeral/no-agent turn kept the old id and the resume guard
  rejected the valid pause as a different agent. (real correctness bug)
- fingerprint: include `promptPrefix` in computeAgentRequestFingerprint, and
  re-send it on resume (ResumeAgentFields + buildResumeFields). Ephemeral agents
  derive their system instructions from promptPrefix, so a resume changing it
  previously passed the pin and rebuilt different instructions. (completes the
  round-6 fingerprint)
- resume: the re-pause branch now persists the segment's accumulated CONTENT
  (filtered), not just artifacts, so an approval that expires/reaps without a
  final resume no longer loses everything streamed during the resumed segment.
- request: carry `manualSkills`/`alwaysAppliedSkills` on the persisted user
  message so a resumed turn's reconstructed requestMessage keeps its skill pills
  instead of dropping them until a full reload.

Deferred (narrow, no safe contained fix yet — see PR thread replies):
- resume rebuild without `addedConvo` for a multi-conversation/added-agent pane
- cross-replica re-prime of manually-selected (not model-invoked) skill files

Tests: stale-agent createJob clearing (Redis integration), promptPrefix
fingerprint match/mismatch (resume.spec.js + policy.spec.ts), re-pause content
persistence (resume.spec.js).

* fix(hitl): address Codex re-review (round 8)

Five findings verified against the code before fixing; the headline is a durable-
resume correctness fix (the fingerprint had surfaced it as a 403):

- resume durability (the important one): persist the graph-determining request
  fields (endpoint, agent_id, model, spec, promptPrefix, ephemeralAgent) on the
  pending action as `resumeContext`, and REPLAY them onto the resume request via
  a router-level middleware that runs before buildEndpointOption. The client
  can't reconstruct the ephemeral-agent config after a reload/cross-session, so
  the round-6/7 fingerprint would 403 a valid durable resume — and even without
  it the rebuilt agent would lose its tools. Replaying server-side rebuilds the
  SAME graph regardless of client state (and a crafted resume can't swap it; the
  fingerprint still matches because the body is restored first).
- RedisJobStore: also clear `isTemporary` on createJob (same class as agent_id):
  a prior temporary turn's flag would otherwise survive a reused conversation
  hash and a later non-temporary resume would save its response as temporary.
- resume: persist `contextMeta` (context-window calibration) onto the saved
  response like BaseClient does, so the next turn can seed its pruner.
- request: carry manualSkills/alwaysAppliedSkills into the onStart metadata
  update (not just the preliminary one it overwrites), so a resumed turn's
  requestMessage keeps its skill pills.

Deferred (narrow — see thread reply):
- saved-agent edited WHILE a run is paused: agent_id matches but the definition
  changed; needs an agent version/config hash, which is a larger change for a
  narrow window.

Tests: resumeContext pick/apply + round-trip (policy.spec.ts), contextMeta +
manualSkills-on-requestMessage (resume.spec.js), isTemporary clearing (Redis
integration).

* style(hitl): prettier line-wrap in policy.spec.ts (R8 lint fix)

* fix(hitl): address Codex re-review (round 9)

Five findings, all fixed (addedConvo — deferred in rounds 7/8 — is now trivial
thanks to the round-8 replay):

- replay addedConvo: add it to RESUME_CONTEXT_KEYS so the resume middleware
  restores the parallel/secondary-agent config from the paused request; the
  client can't reconstruct it, and it determines the rebuilt graph.
- skill pills (the real fix this time): the round-8 onStart metadata write was
  overwritten by trackUserMessage (the authoritative userMessage writer). Carry
  manualSkills/alwaysAppliedSkills in the emitted `created` message and persist
  them in trackUserMessage; widen UserMessageMeta + SerializableJobData.userMessage.
- execute-code files on resume: seed the paused user message's own files onto
  req.body.files before initializeClient — they're excluded from the
  parent-walk code-session rebuild, so an approved code/read-file tool would
  otherwise resume without them.
- in-memory pending-action UI: route ApprovalEvents.ON_PENDING_ACTION in the
  resume replay/pending-event loops to applyPendingActionToMessages (mirror the
  live handler), so a pause that lands in the snapshot window still renders its
  approval controls instead of sitting paused with no UI.
- abort isTemporary: the /chat/abort partial-save now sources isTemporary from
  the job metadata, not req.body (the stop button posts only conversationId), so
  aborting a paused temporary chat no longer persists an orphaned partial.

Tests: addedConvo in pickResumeContext (policy.spec.ts), file-restore on resume
(resume.spec.js), abort-from-job-isTemporary (abort.spec.js).

* fix(hitl): address Codex re-review (round 10) — resume/expiry races

Three concurrency/coherence findings, verified against the code before fixing:

- expiry-sweep CAS scope: both stale-approval sweeps (GenerationJobManager
  expireStaleApprovals and the RedisJobStore requires_action cleanup) called
  expire()/transitionStatus WITHOUT the observed pendingAction.actionId, so the
  CAS only checked status===requires_action. Between the read and the CAS a user
  could resolve the observed action and the run re-pause on a FRESH action; the
  stale sweep would then abort that valid new pause. Now both pass the observed
  actionId as expectActionId, so the CAS only fires for the action read as stale
  (a re-paused action has a different id → no-op).
- resume graph cache: resumeCompletion cached the rebuilt graph (created with
  messages:[]) via setGraph; RedisJobStore.getContentParts prefers a cached
  graph over reconstructing from the chunk log, so a same-replica reload/status
  poll mid-resume returned aggregatedContent missing the pre-pause content. Skip
  setGraph on resume so introspection falls back to the complete chunk
  reconstruction (setContentParts still seeds the in-memory store).
- pending-action UI: applyPendingActionToMessages scheduled a SINGLE
  animation-frame retry then dropped the pending action; Recoil/React updates can
  take several frames under load, leaving a valid requires_action run with no
  approval controls. Retry across frames (bounded at 120) until the target
  message commits.

Test: expire() with a mismatched expectedActionId no-ops while the matching id
expires (pendingAction.spec.ts).

* chore(deps): update @librechat/agents to version 3.2.53 and @langchain/langgraph to version 1.4.7 in package-lock.json and related package.json files

* refactor(hitl): add resolveToolApprovalPolicy seam for layered policy

Extract the single point where tool-approval policy is resolved for a turn
(`resolveToolApprovalPolicy`) and route the run call site through it instead
of reading `endpoints.agents.toolApproval` inline.

Behaviour-preserving: only the `endpoint` layer is wired today, so the result
is identical to reading the app policy directly. The `agent` and `skills`
layers are reserved seams with documented precedence (endpoint owns the
`enabled` kill switch; agent overrides mode/allow/deny/ask/reason; skills may
only tighten), so future per-agent and per-skill policy plumbing lands in one
function rather than at the `createRun` site. Adds focused unit tests.

* fix(hitl): address Codex re-review (round 11) — resume hardening

F1 (P2, security) — applyResumeContext now DELETES any RESUME_CONTEXT_KEY
absent from the persisted context, so the resume body carries exactly the
graph-determining fields the pause had. Previously only defined keys were
overwritten, leaving a client-supplied `addedConvo` (which the request
fingerprint does not cover) in place — a crafted resume could rebuild a
single-agent checkpoint as a different multi-agent graph/tool set.

F3 (P2) — the resume route ACKs (res.json) before initializeClient, so a
post-ACK getMCPRequestContext(req, res) saw the response as finished and
returned undefined, leaving the resumed run without its run-scoped MCP
connection store (approved MCP / OAuth-overlay tools then ran without their
request-scoped connections). Pre-seed the store with a null res +
cleanupOnResponse:false before the ACK and tear it down in the finally,
mirroring the normal stream path (request.js). userMCPAuthMap was already
preserved separately, so credentials were not lost — only the connection store.

Declined: the ApprovalContext NEW_CONVO guard (P2) is a false positive — the
`created` SSE event updates the conversation atom before any pause renders, so
the id is concrete by click time (details in the PR thread).

Tests: policy.spec (absent-key delete) + resume.spec (MCP context pre-seed/cleanup order).

* fix(hitl): address Codex re-review (round 12) — resume fidelity + multi-tool UI

F4 (P2) — temporal prompt vars: resume rebuilt the agent without restoring
req.conversationCreatedAt or req.body.timezone, so {{current_datetime}}-style
vars compiled a different system prompt than the paused graph (resume wall-clock,
unzoned). Add 'timezone' to RESUME_CONTEXT_KEYS (persisted at pause, replayed by
the resume middleware) and restore conversationCreatedAt from the convo before
initializeClient — mirroring the normal path's resolveConversationCreatedAt.

F5 (P2) — multi-tool approval: applyPendingActionToMessages stopped retrying once
ANY tool-call part was tagged, so siblings that rendered on later frames never got
approval controls and the resume route 400'd the partial batch. Add
countTaggedApprovalParts and keep the bounded RAF retry going until every
action_request is tagged (ask_user_question unchanged — one synthetic part).

F6 (P3) — Edit accepted `null`/`[]` (valid JSON, non-object), enabling Submit for
a value the resume route rejects via findIncompleteDecisions. Mirror the server's
plain-object check in the client (store + editIsValid) so Submit only enables for
an accepted value.

Tests: policy.spec (timezone round-trip), resume.spec (conversationCreatedAt
restore), approval.spec (countTaggedApprovalParts).

* fix(hitl): address Codex re-review (round 13) — recurse into subagent approvals

F9 (P2) — a tool paused INSIDE a subagent has its tool_call_id in the parent
subagent tool_call's nested `subagent_content`, not as a top-level message part.
applyToolApproval and countTaggedApprovalParts only scanned top-level content, so
the approval never attached and the round-12 retry loop counted 0 tagged parts and
spun to its frame cap with no controls. Both now recurse into `subagent_content`
(immutably, so React refs update): the nested call gets tagged and is counted, so
the retry terminates. Added approval.spec cases for the nested tag + count.

Note: surfacing the interactive approve/reject controls inside the subagent view is
a deliberate follow-up — ToolApproval -> useResumeSubmit -> useChatContext crashes
when rendered in the portaled subagent dialog (outside the chat/approval providers),
so that needs the controls scoped to the in-provider inline render (or the dialog
wrapped with the providers). This commit fixes the data/traversal layer only.

F7 (discovered-tool history on resume) and F8 (redis chunk TTL pause race) were
verified false positives — see the PR threads.

* fix(hitl): address Codex re-review (round 14) — resume fidelity + expiry relay

F13 (P2) — manualSkills are graph-determining (skill allowed-tools union into the
tool set before tools load) but weren't replayed, so a reload lost the skill tools
and a crafted resume could inject a different skill past the fingerprint. Add
'manualSkills' to RESUME_CONTEXT_KEYS (same replay-only pattern as timezone/
addedConvo; the delete-absent half blocks injection). Not alwaysAppliedSkills —
that's resolved server-side from the DB, not req.body.

F12 (P2) — the resume final SSE built requestMessage from job.metadata.userMessage
(persisted without files), so attachments vanished from the user bubble on resume.
Spread the already-restored req.body.files onto it, matching the normal path.

F11 (P2) — multi-replica approval expiry: RedisJobStore.cleanupRequiresActionIndex
on another replica can win the requires_action->aborted CAS (it sets the hash error
but has no event transport), and the local sweep then skips because the job is no
longer requires_action, so a client subscribed here never gets the terminal error
until the reap path. expireStaleApprovals now relays APPROVAL_EXPIRED_ERROR for a
locally-subscribed job already aborted FOR approval expiry (error-string gated,
idempotent via the errorEvent flag). emitError already publishes cross-replica.

Tests: policy.spec (manualSkills round-trip + inject-drop), resume.spec (final
requestMessage carries restored files).

* fix(hitl): render approval controls for subagent-nested tool pauses (F10)

Round-13 made applyToolApproval/countTaggedApprovalParts recurse into
subagent_content (data), but SubagentDialogPart rendered nested TOOL_CALL parts
with <ToolCall> only and never mounted <ToolApproval>, so a tool paused inside a
subagent showed no controls and the run was unresolvable.

Render <ToolApproval> in SubagentDialogPart's TOOL_CALL branch when the nested
tool_call carries an approval and isn't yet resolved, mirroring the top-level
Part.tsx render. The subagent dialog portals (OGDialog → ReactDOM.createPortal),
but React context flows through the React tree, not the DOM tree, so ToolApproval
resolves ApprovalProvider/ChatContext and the controls work + submit.

Also harden useResumeSubmit: read ChatContext via useContext (non-throwing)
instead of the throwing useChatContext wrapper, so the cards never crash when
rendered outside a ChatContext.Provider (e.g. a search/citation render that passes
chat context as a prop) — they degrade to inert (buildResumeFields returns null).

* style(hitl): re-sort run.ts imports after dev rebase

* fix(hitl): address Codex re-review (round 15) — resume content fidelity

F14 (P2) — hide_sequential_outputs was applied in chatCompletion before
saving/emitting content but not on resume, so a sequential-agent chain that
pauses for HITL and resumes persisted/emitted intermediate outputs the setting
is meant to hide. Extracted the filter into applyHideSequentialOutputsFilter()
and call it from both chatCompletion and resumeCompletion (after handleRunInterrupt,
covering the finalize + re-pause reads of client.contentParts).

F16 (P2) — on a reloaded HITL pause, the DB already holds the paused user row +
partial assistant row; useResumeOnLoad fed those as submission.messages, then
finalHandler/createdHandler appended the same pair via requestMessage/responseMessage,
duplicating the turn (buildTree doesn't dedupe children by messageId). buildSubmission-
FromResumeState now strips the paused user/response rows (by messageId, incl. the
padded/unpadded response id) from submission.messages — they're re-supplied by the
placeholders + final event. Frontend-only; live (non-reload) pause path untouched.

Deferred: F15 (collapsed-card subagent approval registration/visibility) — see thread.

Tests: client.test (filter keeps last + tool_call parts / no-op when off),
useResumeOnLoad.spec (paused pair stripped from submission.messages).

* fix(hitl): address Codex re-review (round 16) — chunk TTL, slot, job replacement

F17 (P2) — chunk-stream TTL on pause-before-chunk. CHUNK_APPEND_LUA derived its
ceiling only from the chunk key's current TTL, so when the chunks key didn't exist
at pause (fire-and-forget append in flight, or an ask-user pause before any chunk),
the on_pending_action append created the stream with only the 20m running TTL while
the approval window is 24h — content evicted before resume. The Lua now also reads
the job key (KEYS[2]); when status == requires_action it takes max(running, TTL(jobKey))
(the approval window transitionStatus set), else the running TTL. Extend-only preserved;
gated on paused status so normal runs never inflate. Both keys share {streamId} (cluster-safe).

F19 (P2) — with LIMIT_CONCURRENT_MESSAGES, the approval prompt was emitted before the
original request released its slot, so a fast Approve got /resume 429'd. handleRunInterrupt
now releases the slot (idempotent via pendingRequestReleased) right after the pause, before
the prompt; the request.js pause branch and resume.js finally only release if it didn't
(no double-release).

F20 (P2) — finalizeResumedTurn never checked the job wasn't replaced before emitDone/
completeJob/saveMessage, so a stale resume could clobber a newer turn that reused the
conversationId. Added the createdAt guard the normal request path uses (skip finalization
when the live job's createdAt != the paused job's).

Deferred: F18 (subagent_content not reconstructed on Redis resume) — joins the subagent
cluster (F15). See thread.

Tests: RedisJobStore integration (pause-before-chunk gets approval TTL; running stays short),
resume.spec (skip finalization on replacement; no double slot release on re-pause).

* 🛡️ fix: Guard HITL terminal side-effects against job replacement

Jobs are keyed by streamId == conversationId, so a new request REPLACES the
running one on the same conversation. The replaced generation's tail must not
clobber the live generation's state. Each path now re-reads the live job and
compares createdAt against the generation's captured identity before acting.

- Thread the generation's createdAt onto the client (request.js + resume.js)
  as client.jobCreatedAt — the identity every guard compares against.
- handleRunInterrupt: skip approvals.pause when this run is no longer the live
  job, so a stale interrupt can't flip the NEWER job to requires_action.
- chatCompletion finally: skip the checkpoint prune when replaced, so an older
  run's late finally can't delete the newer run's resume checkpoint.
- resume catch-path: gate emitError/completeJob/prune behind a stillLive check
  (fail-open if the read throws), mirroring finalizeResumedTurn's success guard.
- Persist the turn's uploaded files on job.metadata.userMessage (authoritative
  trackUserMessage writer) and prefer them on resume over the user DB row, whose
  save can still be racing a fast /resume.

Tests: 13 guard-predicate cases in jobReplacement.spec.js.

* 🔁 fix: Harden HITL resume — ownership re-check, file seeding, deferred-tool replay

Three follow-ups to the round-17 job-replacement guards (Codex review 4594099963):

- G1 (resume.js): the success-path ownership guard runs at the START of
  finalizeResumedTurn, but saveMessage + first-turn title generation await long
  enough for a new request to replace the job on the same conversationId. Re-read
  the live job immediately before emitDone/completeJob/prune so the terminal writes
  can't tear down the REPLACEMENT job — mirrors the catch-path guard.

- G2 (request.js): onStart's metadata/chunk writes that persist the turn's files
  are fire-and-forget, so a fast approval could read job.metadata.userMessage before
  files landed. Seed files into getPreliminaryUserMessage instead — that write is
  AWAITED before the run starts, so files are durable before any interrupt can emit.

- G3 (run.ts + client.js + resume.js + IJobStore.ts): the resumed graph is rebuilt
  with messages: [], so createRun's tool_search-discovery scan finds nothing. A
  deferred tool discovered earlier in the turn (and targeted by the paused call) was
  therefore absent from the rebuilt schema-only toolMap — resume would throw "unknown
  tool" (no loadRuntimeTools fallback is wired). Capture discovered tool names at
  pause via extractDiscoveredToolsFromHistory(run.getRunMessages()), persist them on
  job.metadata.discoveredTools, and replay them into createRun's new discoveredToolNames
  input (merged with message-extracted names, gated on hasAnyDeferredTools — inert
  otherwise). A new createRun test proves the deferred tool is promoted with the replay
  and absent without it (reproducing the bug).

Tests: real createRun deferred-replay suite (run-summarization.test.ts) + G1/G2/G3
guard predicates (jobReplacement.spec.js). Full suite green.

* 🔒 fix: Close HITL resume metadata + file-substitution + pause-race gaps

Four findings on the round-18 commit (Codex review 4594430222):

- H1 (P1, regression in round-18 G3): the discoveredTools captured at pause never
  reached resume — three metadata allowlists dropped it: GenerationJobManager
  .updateMetadata, RedisJobStore.deserializeJob, and buildJobFacade (plus the
  GenerationJobMetadata type). Added discoveredTools to all four, so the deferred-tool
  replay actually works end-to-end (in-memory store already kept it via Object.assign).

- H2 (P2, security): /resume honored a client-supplied `files` array, letting a crafted
  client resume an approved code/read-file tool against a DIFFERENT file set than the one
  approved (files aren't in the resume fingerprint/context). Resume now ALWAYS sources
  files from the paused job (metadata → DB row), clearing any client-supplied set.

- H3 (P2, ephemeral fidelity): non-default model parameters (temperature, max tokens,
  custom endpoint params) were lost on resume — ephemeral agents derive them from the
  request body, which the resume payload omits. Capture the resolved model_parameters in
  resumeContext at pause and replay them onto the body on resume (excluding `model`, which
  is replayed via the fingerprinted RESUME_CONTEXT_KEYS path). Saved agents already source
  these from the DB.

- H4 (P2, Redis race): a pause landing between the resume snapshot and the Pub/Sub
  subscription reached neither resumeState.pendingAction nor (Redis) pendingEvents, and
  approval events aren't persisted to replayEvents — the client attached to a paused job
  with no approval UI. subscribeWithResume now re-reads the live job AFTER subscribing and
  surfaces the pending action if the snapshot missed it (live read, no staleness).

Tests: discoveredTools metadata round-trip + subscribeWithResume re-read (pendingAction
.spec.ts); client-file substitution rejection (resume.spec.js); model-parameter replay
predicate (jobReplacement.spec.js).

* 🧹 fix: Clear stale discovered tools, release slot on claim error, extend run-step TTL

Three follow-ups on the round-19 commit (Codex review 4594783691):

- I1 (P2): the round-19 discoveredTools field wasn't cleared on Redis streamId reuse.
  HSET only overwrites listed fields and handleRunInterrupt only writes discoveredTools
  when THIS turn discovers a deferred tool — so a replacement turn that pauses without its
  own discovery inherited the prior run's tool names and force-loaded undiscovered deferred
  tools on resume. Added discoveredTools to createJob's staleHitlFields HDEL list (the
  in-memory store already builds a fresh object, so it was Redis-only).

- I2 (P2): with LIMIT_CONCURRENT_MESSAGES, approvals.resolve runs after the slot increment
  but before the run's try/finally, so a store/Redis error there leaked the slot until the
  counter TTL expired (spurious 429s on retry of the still-paused approval). Wrapped the
  claim in try/catch that decrements the slot and returns 500.

- I3 (P3): saveRunSteps did SET ... EX running unconditionally, resetting the run-steps key
  to the 20-min running TTL even while the job is paused for the longer approval window —
  a reload after that window lost the tool timeline. Now uses a paused-window TTL script
  mirroring the chunk-stream no-shrink behavior (extends to the approval window when the
  job hash is requires_action).

Also fixes a latent strict-tsc cast error in the round-19 pendingAction test.

Tests: claim-throws-releases-slot (resume.spec.js); discoveredTools cleared on reuse +
saveRunSteps preserves the paused TTL (RedisJobStore integration, USE_REDIS).

* 🛡️ fix: Guard fast-resume save race, gate HITL to resumable routes, expire on stale submit

Three findings on the round-20 commit (Codex review 4595045652):

- J2 (P1): a fast /resume can claim + finalize the COMPLETED response while the original
  request's pause branch is still awaiting `response.databasePromise`; the later
  unfinished-save then overwrites the completed content. Re-check the job is still paused on
  THIS generation's action (a claim leaves requires_action; a replacement bumps createdAt)
  before marking the row unfinished; fail open on a read error.

- J3 (P1): the tool-approval wiring (humanInTheLoop + PreToolUse hook + checkpointer) was
  applied to EVERY createRun caller when toolApproval.enabled, but the OpenAI-compatible and
  Responses controllers never inspect run.getInterrupt() or persist a pending action — an
  approval-gated tool would pause there with no approval surface or resume endpoint and the
  route would emit a normal final response / [DONE] with the tool call dangling. Gate the
  wiring on a new createRun `hitlCapable` flag, set only by AgentClient (chat + resume).

- J4 (P2): a stale-action 409 on submit returned without driving expiry, leaving the job
  requires_action with a dead action until the periodic sweeper ran — any attached SSE client
  got no terminal event and the stream appeared to hang. Extracted GenerationJobManager
  .expireApproval(streamId, actionId) (expire CAS + terminal SSE, shared with the sweeper) and
  call it from the resume route when the observed action is stale.

J1 (nested subagent approval controls not mounting while the details dialog is closed) is a
valid frontend issue in the deferred subagent-HITL path — tracked separately (replied on the
thread) since the fix touches the shared dialog primitive and needs UI verification.

Tests: HITL-gate both directions (run-summarization.test.ts); expire-on-stale-submit
(resume.spec.js); fast-resume unfinished-save guard predicate (jobReplacement.spec.js).

🦥 perf: Lazy-Load Agent Version History in Editor (#13977)
Opening the agent editor fetched the full `versions` array (each a complete
config snapshot) alongside the agent, so agents with large histories were slow
to open. Version history is now loaded only when the user opens it.

- Add `getAgentWithVersionCount` (aggregation: version count, no versions array)
  and `getAgentVersions` data-schemas methods.
- `getAgentHandler` returns the version count without the heavy array; add
  `GET /agents/:id/versions` (EDIT-gated) for lazy retrieval.
- Add `useGetAgentVersionsQuery`; VersionPanel reads current config from the
  cached expanded query and fetches versions on open. Revert keeps the expanded
  cache and versions query in sync.

🪝 feat: HITL Tool Approval Scaffolding (Slice A) (#12938)
* 🪝 feat: HITL Tool Approval Scaffolding

Adds the foundational types, job-state, config schema, and policy module
for human-in-the-loop tool approval. Purely additive — no behavior change
on existing runs. Lands ahead of the agents-SDK interrupt/checkpointer
integration so both tracks can land independently.

- LangChain HumanInterrupt-shaped types in `Agents.*` namespace
  (`HumanInterruptPayload`, `ToolApprovalRequest`, `ToolReviewConfig`,
  `PendingAction`, `ToolApprovalResolution`); `ToolCall`/`ToolCallDelta`
  gain an optional `approval` field.
- New `requires_action` job status (non-terminal) plus `pendingAction`
  field on `SerializableJobData` and `GenerationJobMetadata`. Both stores
  treat the status as paused-but-alive; Redis `updateJob` has explicit
  `requires_action`/`running` transition branches that refresh the hash
  TTL, manage the `runningJobs` set, and `HDEL pendingAction` on resume.
  Both stores include `requires_action` in `getActiveJobIdsByUser`.
- `GenerationJobManager` gains `markRequiresAction`, `getPendingAction`,
  `clearPendingAction`; `getJobCountByStatus` aggregates the new status.
- `endpoints.agents.toolApproval` config (`default`/`required`/`excluded`)
  and a policy module exporting `decideToolApproval`, `requiresApproval`,
  and `buildPendingAction` (the LangChain-shaped payload builder).
- 20 unit tests covering policy resolution and the manager lifecycle.

* 🧭 refactor: Align HITL Surface with Agents SDK Permissions Model

Reshapes Slice A on top of the agents SDK's now-landed HITL surface
(`createToolPolicyHook`, discriminated `HumanInterruptPayload`, `'bypass'`
mode naming). Host stops reimplementing evaluation logic and becomes a
config mapper + payload wrapper.

Schema (data-provider):
- `toolApproval` shape now mirrors SDK `ToolPolicyConfig` 1:1:
  `mode: 'default' | 'dontAsk' | 'bypass'`, plus `allow` / `deny` / `ask`
  glob lists and an optional `reason` template. `enabled` is the
  LibreChat-only admin kill switch.
- `'bypass'` (not `'bypassPermissions'`) — matches the SDK's surface.

Types (`Agents.*` namespace):
- `HumanInterruptType` extended to `'tool_approval' | 'ask_user_question'`.
- `HumanInterruptPayload` is now a discriminated union — `tool_approval`
  carries `action_requests` + `review_configs`; `ask_user_question`
  carries a free-form question with optional curated options.
- New: `AskUserQuestionRequest`, `AskUserQuestionOption`,
  `AskUserQuestionResolution`.
- `ToolApprovalDecision` (string union) renamed to
  `ToolApprovalDecisionType` to free the `Decision` name for the SDK's
  discriminated object union later.
- `ToolApprovalResolution` gains `reason?` and `scope?: 'once' | 'session'
  | 'always'` so route signatures stabilize before persistence lands.

Policy module (`packages/api/src/agents/hitl/policy.ts`):
- Drop `decideToolApproval` / `requiresApproval` / `ToolRef` — the SDK's
  `createToolPolicyHook` handles full evaluation
  (`deny → bypass → allow → ask → dontAsk → fallthrough(ask)`).
- Add `isHITLEnabled(policy)` — the kill-switch predicate that gates the
  SDK's `humanInTheLoop: { enabled: false }` opt-out in Slice B.
- Add `mapToolApprovalPolicy(policy)` — strips `enabled`, returns a
  `ToolPolicyConfig` to feed `createToolPolicyHook`. Structural mirror of
  the SDK type so this compiles before the SDK upgrade ships.
- Reshape `buildPendingAction(payload, ctx)` to wrap any
  `HumanInterruptPayload` with job context — accepts SDK output directly.
- Add `buildToolApprovalPayload(...)` and `buildAskUserQuestionPayload(...)`
  helpers for synthesizing payloads in tests / pre-SDK flows.

Tests:
- 22 new unit tests covering the mapper, predicate, and payload builders;
  20 → 27 total pass across policy + manager-lifecycle suites.

* 🪢 chore: Import ToolPolicyConfig From `@librechat/agents`

The SDK type now ships in 3.1.77 (already pinned on `dev`), so the
structural mirror in `policy.ts` is redundant. Drop the local interface
and import directly so future SDK changes to `ToolPolicyConfig` propagate
without our `mapToolApprovalPolicy` going stale.

* 🔑 fix: Carry tool_call_id On ToolReviewConfig (HITL)

`ToolReviewConfig` was joining with `ToolApprovalRequest` by position only.
That breaks the moment a single batch contains the same tool called twice
(e.g. a model fanning out parallel `mcp:server:search` calls): the UI can't
tell which review config applies to which action request once it filters
or reorders.

Mirrors the SDK's `ToolApprovalReviewConfig` shape — `tool_call_id` is the
join key, `action_name` is retained for display only.

Also: drop a JSDoc warning on `isHITLEnabled` so a future contributor doesn't
wire `humanInTheLoop: { enabled: true }` without supplying a host
checkpointer — the SDK's `MemorySaver` fallback is process-local and
silently breaks resume across worker hops.

- `Agents.ToolReviewConfig` adds `tool_call_id: string`
- `buildToolApprovalPayload` populates `tool_call_id` per review config
- New test covers the duplicate-tool batch case (two parallel calls to
  the same tool); 27 → 28 tests

* 🏛️ refactor: Deepen HITL approval lifecycle into one race-safe seam

Architecture-review candidate #1 (+ #4). The requires_action lifecycle was
three shallow pass-throughs over updateJob with the legal transitions
smeared across JSDoc, the JobStatus union, and each store adapter — and the
resume transition was NOT race-safe: the Redis lua checked existence, not
status, so two concurrent approval submits both drove the run (re-executing
tools / double-billing).

- IJobStore.transitionStatus: atomic compare-and-set status transition that
  only fires if the job is currently `from`. InMemory: sync compare. Redis:
  single-node lua with a status guard (cluster best-effort, matching the
  existing posture); reconciles membership sets + TTLs to `to`.
- New ApprovalLifecycle module: pause / peek / resolve / expire — guarded,
  race-safe transitions behind one interface. resolve() returns true to
  exactly one concurrent caller; the previously-undefined
  requires_action → aborted expiry edge is now explicit; peek treats
  past-expiresAt as gone (lazy expiry).
- GenerationJobManager exposes `approvals` and delegates; the three shallow
  methods (mark/get/clearPendingAction) are removed — callers cross the deep
  interface.
- #4: typeContract.spec asserts the SDK <-> data-provider HITL types stay
  compatible (fails the build on drift); RedisJobStore validates the
  pendingAction shape on deserialize instead of a bare JSON.parse (defends
  the cold-resume path against malformed/stale records).
- Tests rewritten at the deep interface: double-resolve wins once,
  pause-on-terminal rejected, explicit expiry, lazy-expiry peek.

No Slice B wiring — this deepens the existing scaffolding so the future
resume route and run seam are born crossing one race-safe interface.

* 🛡️ fix: Address Codex review on the HITL approval lifecycle

Seven findings on the lifecycle deepening (089ba09f9), all valid:

- F3 actionId guard: resolve/expire take an expectedActionId; pause records a
  flat `pendingActionId` the atomic CAS guards on, so a stale decision can't
  resume a job that has since paused for a different action.
- F4 cluster single-winner: transitionStatus now decides the winner with an
  atomic CAS on the single-slot job hash (one Lua, cluster-safe), then
  reconciles cross-slot membership sets — two concurrent resolves can no
  longer both win on Redis Cluster.
- F1 resume reaping: resolve refreshes `lastActiveAt`; both stores' stale-
  running failsafes key off it, so a long-paused approval isn't reaped right
  after resuming.
- F2 expire completedAt: expire writes completedAt so terminal cleanup
  reclaims the job (InMemory only cleans terminal jobs with completedAt set).
- F5 facade: buildJobFacade copies pendingAction into metadata so status/
  resume routes can render the prompt.
- F6 resume metadata: PendingAction + buildPendingAction carry the SDK
  interruptId/threadId needed to rebuild Command({ resume }) cross-process.
- F7 mirror: data-provider AskUserQuestionRequest gains optional description.

Tests added at the interface: stale-actionId resolve rejected, expire sets
completedAt. tsc + lint clean; policy + type-contract specs pass.

* 🛡️ fix: Address Codex round 2 on the HITL Redis adapter

Five P2 findings on abf4b86291, all valid Redis-adapter consequences of
round 1:

- G1 terminal cleanup on expiry: transitionStatus's terminal path now runs
  the same chunk/run-step/userJobs cleanup as updateJob (extracted into a
  shared applyTerminalContentCleanup). Expired approvals no longer leave
  Redis stream contents around for the full running TTL.
- G2 pause via updateJob mirrors pendingActionId, so a pause through the
  generic path carries the flat field the stale-decision guard compares.
- G3 resume via updateJob refreshes lastActiveAt (and clears pendingActionId),
  matching transitionStatus so a long-paused job isn't reaped post-resume.
- G4 getActiveJobIdsByUser excludes a requires_action job whose pendingAction
  is past expiry (both stores), via shared isPendingActionExpired — the client
  stops polling an expired prompt.
- G5 createJob clears stale pendingAction/pendingActionId/lastActiveAt on a
  reused streamId, so a fresh run never exposes a prior run's approval metadata
  and cleanup keys off the new createdAt.

Tests added: expired pending-approval excluded from the active set. tsc +
lint clean; policy + type-contract specs pass.

* 🛡️ fix: Address Codex round 3 — approval expiry lifecycle completeness

Three P2 findings on 780833d908, all valid:

- H1 status consistency: /chat/status now treats a non-expired
  requires_action job as active (matching /chat/active), so a client
  refreshing while an approval is pending resumes/subscribes instead of
  treating the run as finished and stranding it.
- H2 active expiry: cleanup now finalizes past-expiry requires_action jobs
  (→ aborted) in both stores instead of only filtering them from the active
  list — an expired prompt no longer lingers resident until key TTL. Redis
  routes through transitionStatus (terminal content cleanup); in-memory marks
  terminal + reclaims.
- H3 resumed liveness: in-memory stale-running check uses
  max(lastActivity, lastActiveAt, createdAt), so a just-resumed job isn't
  reaped on a stale per-chunk lastActivity entry before the next chunk.

Test added: in-memory cleanup finalizes + reclaims a past-expiry approval.
tsc + lint clean; policy + type-contract specs pass.

* 🛡️ fix: Address Codex round 4 — paused-job edge cases across the stack

Five P2 findings on 4324a4e776, all valid:

- I1 message validation: validateMessageReq's active-job read bypass now
  accepts a live requires_action job, so a new-conversation run that pauses
  before its final save can recover the prompt instead of 404ing.
- I2 expire targets the observed record: resolve()'s expired path passes
  `expectedActionId ?? job.pendingAction.actionId`, so a concurrent
  resume+re-pause can't let expire abort a different action.
- I3 stale/malformed prompts: new isPendingActionStale (missing OR expired)
  drives active-listing exclusion + cleanup expiry in both stores, and the
  status route + middleware require a live pendingAction — a requires_action
  job whose pendingAction was dropped on deserialize no longer reads active.
- I4 in-memory parity: InMemory updateJob mirrors pendingActionId on pause and
  clears it + refreshes lastActiveAt on resume (matching RedisJobStore), so a
  pause via the generic path is still resolvable by actionId.
- I5 long approval windows: paused-job live TTL (job/chunks/run-steps) now
  covers pendingAction.expiresAt + grace (pauseTtlSeconds), on both the
  transitionStatus and updateJob pause paths, so Redis can't evict a paused
  job before its decision window closes.

tsc + lint clean; policy + type-contract specs pass.

* 🛡️ fix: Codex round 5 — refuse unresolvable resolves; expose pending action

Two of three findings on c8abd826e1 (the third deferred to Slice B):

- J3 resolve() refuses a requires_action job that has lost its pendingAction
  (e.g. a malformed record dropped on deserialize): it expires/finalizes the
  job instead of driving a resumed run with no reviewed interrupt payload —
  consistent with how active-listing + cleanup already treat a stale prompt.
- J2 /chat/status returns the live pendingAction for a paused stream, so a
  client rebuilding from status (reload / cross-replica) has the action id +
  payload to render and submit the prompt, not just "paused".

Deferred (Slice B): J1 — emitting a terminal SSE event on approval expiry so
already-subscribed clients close. The store-level lifecycle can't emit
transport events, and there are no live SSE subscribers to a paused stream
until the Slice B runtime wiring exists; tracked for that work.

tsc + lint clean; policy + type-contract specs pass.

* 🛡️ fix: Codex final round — paused-job TTL + pendingAction in resume contract

Two of three findings on e7d9cf21b6 (third deferred to Slice B):

- K2 paused-job TTL: a paused (requires_action) job no longer inherits the
  20-minute running TTL — it uses a dedicated requires_action backstop
  (default 24h, configurable) so a no-expiry approval (the buildPendingAction
  default), which the API treats as live, isn't evicted by Redis mid-window.
  A longer pendingAction.expiresAt still extends beyond the backstop.
- K3 resume contract: pendingAction is now carried on the typed ResumeState
  (data-provider) and populated by getResumeState for a live paused job, so a
  reloading / cross-replica client can rebuild the prompt from resumeState
  (the contract useResumeOnLoad actually reads), not just a loose status field.

Deferred (Slice B): K1 — emit a terminal SSE event on expiry so already-
subscribed clients close. Requires the manager/eventTransport layer (the
store-level lifecycle and cleanup loops have no transport access) and has no
live subscriber until the Slice B subscribe/resume path exists; tracked there.

tsc + lint clean; policy + type-contract specs pass.

* ♻️ refactor: dedup HITL transition path + liveness predicate (arch review)

Two follow-ups from the post-hardening architecture re-review — both pure
dedup, no behavior change:

A — collapse the dual status-transition path. transitionStatus is now the
   sole membership-aware transition (running ⇄ requires_action). Removed the
   updateJob requires_action/running branches and the now-orphaned
   transitionToRequiresAction / transitionToRunning / refreshLiveJobTtls, plus
   the per-store pause/resume mirror logic that had to be re-synced into parity
   across review rounds (G2/G3/I4/I5). updateJob is back to a plain field
   writer + terminal cleanup. The Redis integration tests that drove
   updateJob({status}) now drive transitionStatus (the real path).

B — one canonical "is this approval live?" predicate. isPendingActionStale /
   isPendingActionExpired are exported from @librechat/api and used by the
   stores, ApprovalLifecycle (dropped its private isExpired), the /chat/status
   route, and validateMessageReq — replacing 3 inlined re-derivations that were
   the drift source behind several review findings.

tsc + lint clean; policy + type-contract specs pass. Redis integration specs
(migrated) are CI-verified.

💾 feat: Persist Context Breakdown & Branch/Total Usage Cost (#13734)
* 💾 feat: Persist Context Breakdown & Branch/Total Usage Cost

Persist the granular context breakdown and per-response usage/cost on the
response message metadata, and re-derive branch + total usage/cost from a
per-message index so the popover survives reloads and is branch-aware live.

- Add aggregateEmittedUsage + buildPersistedContextUsage helpers in
  packages/api; capture the latest visible snapshot and every emitted
  on_token_usage payload via contextUsageSink/usageEmitSink.
- Attach metadata.contextUsage (Part A) and metadata.usage (Part B) on the
  agents response message in sendCompletion.
- Carry per-message usage on the token index; add sumTotalUsage/setEntryUsage
  and branch-scoped usage on sumBranch.
- Repurpose the session accumulator into a single in-flight pending holder;
  flush it into the index at finalize; hydrate breakdowns on load.
- Render branch cost with a conditional all-branches total in the breakdown.

* 🧹 chore: Remove orphaned com_ui_session_cost i18n key

* 🩹 fix: Address Codex review — normalize usage server-side, fix reload deltas

- Persist per-event-normalized display units in metadata.usage (TResponseUsage)
  so reloaded mixed-provider turns match the live session; client reads them
  directly instead of re-normalizing with a single stamped provider (P2).
- Persist completedOutputTokens (final call output) on metadata.contextUsage so
  a reloaded multi-call turn adds the post-snapshot delta, not the full
  tokenCount the snapshot already counts (P2).
- buildIndex preserves a prior entry's immutable usage when a rebuilt cache
  message lacks metadata.usage, so a mid-session rebuild (regenerate) keeps a
  sibling branch's flushed cost (fixes the e2e regenerate failure).
- Track costKnown so turns saved with contextCost off don't render $0.00 when
  cost display is later enabled (P3).
- Use an epsilon for the all-branches cost comparison to avoid a spurious total
  row from float summation order (P3).
- Update unit/integration/e2e tests for the new shapes; regenerate e2e asserts
  the all-branches total after reload (deterministic via persisted metadata).

* 🩹 fix: Address Codex round 2 — pending leak, cost coverage, reload delta

- Clear the in-flight pending usage on terminal abort/error (resetLive), so a
  stopped generation's tokens no longer merge into the next response (P2).
- costKnown now means COMPLETE coverage (ANDed): a branch mixing cost-bearing
  and cost-less turns is flagged incomplete and the cost row is hidden rather
  than rendering an under-reported total (P2).
- Drop the tokenCount fallback for completedOutputTokens on reload: only the
  persisted post-snapshot delta is used, so a multi-call turn whose provider
  emitted no usage_metadata no longer double-counts earlier output (P2).
- Update tokens.spec for AND coverage semantics + incomplete-cost case.

* 🩹 fix: Address Codex round 3 — no-usage snapshots, total coverage, provider-less cache

- Skip persisting metadata.contextUsage when the response emitted no primary
  usage event: without a known post-snapshot output the granular gauge would
  undercount the reply on reload, so fall back to the coarse per-message
  estimate instead (P2).
- Gate the all-branches cost row on totalUsage.costKnown so an incomplete total
  (a sibling saved without cost) never renders an under-reported figure (P2).
- aggregateEmittedUsage/finalCallOutputTokens now normalize per-event with the
  client's magnitude fallback (normalizeEventUnits) instead of billing
  splitUsage, so provider-less cached events match live on reload (P2).
- Add backend test for the provider-less cached case.

* 🩹 fix: Address Codex round 4 — abort attribution, complete cost coverage

- aggregateEmittedUsage persists cost only when EVERY call was priced; a partial
  pricing failure now omits cost so the client treats coverage as unknown rather
  than reading an under-reported sum as authoritative (P2).
- finalizeUsage flushes pending into the response entry only when events were
  folded this session (eventCount > 0), so a late/second resumable subscriber
  carrying persisted metadata.usage keeps it instead of being overwritten with
  an empty pending record (P2).
- On user stop, attribute the in-flight pending usage to the partial response
  (new attributePending handler) instead of discarding it in resetLive — the
  stopped reply's billed tokens are kept and still can't leak into the next
  response; resetLive's discard remains for the error path (P2).

* 🐛 fix: Persist branch cost across branch switches via sticky usage history

Branch cost vanished on switching to a sibling branch (until a new turn) — the
cost analog of the granularity bug. buildIndex rebuilds the token index from the
messages cache; a sibling generated this session whose cache message lacks
metadata.usage (and is transiently dropped from the cache during regenerate)
lost its live-flushed usage, so sumBranch found none and the cost row hid.

Fix: a sticky per-response usage map (conversationId → messageId → usage),
written by setEntryUsage and never rebuilt from the cache — the usage counterpart
of snapshotsByAnchorFamily for the breakdown. buildIndex/upsertEntries restore an
entry's usage from it when the message carries none; cleared on convo switch and
migrated with the index. Add unit coverage for the drop-then-readd regression and
an e2e assertion that branch cost survives a branch switch.

* 🐛 fix: Re-index on branch switch so branch cost survives the switch

The sticky usage history alone didn't fix the reported branch-switch cost drop:
on a branch switch no cache `updated` event fires, so the index subscriber never
re-ran, and the post-regenerate rebuild was skipped while `isSubmitting` was
still true — leaving the index stale and missing the now-viewed branch's
response entirely (sticky can only restore entries present in a rebuild).

Re-index from the messages cache on every tail change (created/finalize AND
branch switch), not just while submitting. The cache holds the full message set
at switch time, so the viewed branch's response is re-added and its usage
restored from metadata.usage or the sticky history → sumBranch finds it and the
branch cost renders. Verified locally: the branch-switch e2e now passes (the
cost section shows both the branch row and the all-branches total). Also fixed
that e2e assertion to target a single cost value (strict-mode safe).

* 🩹 fix: Handle stopped-stream usage — reset pending + persist abort metadata

Codex round (stop/abort edges):
- Resumable explicit-stop (intentional SSE close) reset UI state but never
  cleared pendingUsageFamily, so usage folded before the stop leaked into the
  next response in the conversation. Discard pending on intentional close
  (resetLive); a resume re-folds via backfillUsage, so nothing is lost.
- The abort save path (abortMiddleware) persisted the stopped response without
  metadata.usage/contextUsage, so its cost + breakdown vanished on reload.
  Rebuild both from the job's persisted tokenUsage (emitted payloads incl. cost)
  and contextUsage snapshot — parity with the normal sendCompletion path;
  breakdown gated on a primary usage event like buildResponseMetadata.

Deferred (per scope decision): mid-stream branch-switch transiently shows the
streaming branch's pending on the viewed sibling (cosmetic, until finalize).

* 🩹 fix: Persist abort metadata on the real agents route + tighten snapshot gate

Codex round (corrects last round's wrong-path fixes):
- Stopped AGENTS responses are saved by routes/agents/index.js (/chat/abort),
  not abortMiddleware — so last round's metadata fix never ran for them. Moved
  the rollup/snapshot builder into packages/api as buildAbortedResponseMetadata
  (shared, unit-tested) and applied it in BOTH abort save paths, so a stopped
  agent reply keeps its cost + breakdown on reload.
- Persist the breakdown only when the FINAL visible call emitted usage: track a
  per-response snapshot count and require primaryUsageCount >= snapshotCount.
  Previously any earlier primary usage event passed the gate, so a multi-call
  turn whose final call emitted no usage_metadata used an earlier call's output
  as completedOutputTokens (already counted by the latest snapshot) → reload
  over-reported. Now it falls back to the coarse estimate.

Resumable stop pending-reset (prior round, 3cde6fe035) already flows through
clearAllSubmissions → SSE close → the intentional-close handler's resetLive.
Deferred per scope: mid-stream branch-switch pending attribution (tracked).

* 🩹 fix: Abort breakdown over-count + resume re-fold after pending discard

Codex round (on the re-applied abort/snapshot work):
- buildAbortedResponseMetadata now persists ONLY the usage/cost rollup, not the
  context breakdown. The abort path can't tell whether the final call emitted
  usage (the job stores only the latest snapshot, not a count), so persisting
  the breakdown risked reusing an earlier call's output as completedOutputTokens
  (already in the snapshot) → reload over-count. Stopped/incomplete responses
  now fall back to the coarse gauge estimate, which is safe and apt.
- resetLive now also forgets the conversation's folded usage-event identities
  (clearUsageFolded). Discarding pending on a terminal/intentional close left
  the folded keys set, so a later resume's backfillUsage saw the persisted
  events as duplicates and never rebuilt pending — leaving the response's usage
  missing until a full reload. Clearing them lets the resume re-fold.

🛡️ feat: Configurable Message PII Filter (#13602)
* 🛡️ feat: Reject chat messages matching configured credential patterns

Adds an opt-in `messagePiiFilter` middleware mounted on the agent
chat route ahead of `moderateText`. When the configured patterns
match the user's input the request is refused with 400, so the
credential never reaches OpenAI moderation, the model, or MongoDB.
Three starter patterns ship by default and operators can subset
them or add their own regex via `customPatterns` in librechat.yaml.

* 🧪 test: Memoize compiled patterns + add middleware spec

Memoize the compiled pattern array via a WeakMap keyed by the
messagePiiFilter config object so repeat requests against the same
config skip the per-request RegExp construction. Cache entries are
released automatically when the config object itself rotates.

Adds packages/api/src/middleware/messagePiiFilter.spec.ts covering
the default-starter rejections, the starterPatterns subset and
empty-array semantics, customPatterns matching layered on top of and
in place of the starters, the no-config and empty-text pass-through
paths, and a memoization regression check.

* 🛡️ fix: Skip invalid customPattern regexes instead of crashing the request

Admin DB overrides for `messagePiiFilter.customPatterns` reach
`req.config` via `mergeConfigOverrides`, which deep-merges raw
override values without re-running `configSchema`. A typo'd regex
like `(` would slip past the YAML-load validation and throw inside
`new RegExp(...)` during `compile()`, returning 500 for every chat
request until the operator rolled the override back.

Wrapped the per-pattern compile in a try/catch that logs the
invalid pattern id + reason and skips it, so other valid patterns
(starters and other custom entries) keep filtering. Added a
regression test alongside the existing spec.

* 🛡️ feat: Extend PII filter to OpenAI-compatible and Responses agent APIs

The chat-route middleware operates on `req.body.text`, but the remote
agent API endpoints (`/api/agents/v1/chat/completions`,
`/api/agents/v1/responses`) accept the same prompt content as a
`messages` array or an `input` field. A caller using their API key
could send a credential-shaped value through either route and bypass
the configured PII filter even though they share the same agent and
model backbone the middleware is meant to guard.

Factored out `findPiiMatchInMessages`, a tolerant walker that handles
both `content: string` and `content: ContentPart[]` user-message
shapes against the same compiled, cached pattern list. Wired it into
the OpenAI-compat controller after agent lookup and into the
Responses controller right after `convertToInternalMessages`. Each
returns the endpoint's native 400 error shape
(`sendErrorResponse` / `sendResponsesErrorResponse`) with the
`message_pii_filter_block` code when a user message matches.

* 🩹 test: Add findPiiMatchInMessages to OpenAI + Responses controller mocks

The OpenAI-compat and Responses controller specs mock `@librechat/api`
with a hand-listed object. The new `findPiiMatchInMessages` export
wired into both controllers in 3ea35af9a was missing from those
mocks, so the production lookup returned undefined and the controllers
threw at request time under jest. Added the missing entries (default
mock: returns null so the handlers fall through to the existing happy
paths). All 278 agents-controller tests pass locally.

* 🧹 refactor: Namespace messagePiiFilter under messageFilter.pii + fix import order

Renames the yaml field `messagePiiFilter` to `messageFilter.pii`, the
module to `messageFilterPii`, the factory to `createMessageFilterPii`,
the type to `MessageFilterPiiConfig`, and the error code to
`message_filter_pii_block`. The wrapper `messageFilter` namespace
gives future safety filters (e.g. `messageFilter.toxicity`) a place
to plug in without restructuring the config later. The
`findPiiMatchInMessages` helper kept its name because it already
describes what it does at the value level.

Also fixes import order Danny flagged on the OpenAI-compatible and
Responses controllers: `findPiiMatchInMessages` was appended at the
bottom of two `require('@librechat/api')` destructures rather than
placed in the length-sorted slot the house style expects.

* 🧹 chore: Length-sort the general require destructure in responses.js

Reorders the general sub-group inside the `require('@librechat/api')`
destructure shortest to longest so the whole block conforms to the
length-sort rule the file's `// Responses API` sub-group already
follows. Pure reorder, no other changes.

* 🧹 chore: Length-sort the defaultConfig block in AppService

Reorders the `defaultConfig` keys in `packages/data-schemas/src/app/service.ts`
shortest-line to longest-line, with the explicit-value entries
(`mcpConfig`, `fileStrategies`, `cloudfront`) trailing the shorthand
ones. Pure reorder, no behavior change.

🪜 feat: Add OpenID Role Sync (#13415)
* Shared Role-Sync Core

* Environment Configuration

* Browser OpenID Wiring & improved shared component

* API Auth Wiring

* Improved Role Lookup

* added example for sync env

* small simplification

* protect existing manual assigned ADMIN Roles

* fix: Apply OpenID role-sync fallback for present-but-empty claims

Both role-sync call sites skipped on a falsy `openIdRoleValues`, treating an
empty claim string ('') the same as a missing claim and returning before
`selectOpenIdRole` could apply the configured fallback role. An IdP emitting
an empty roles claim for a user with no mapped groups left the stale local
role in place instead of the authoritative fallback.

Skip only when the helper returns `undefined` (missing/invalid), letting an
empty string flow through to fallback selection — consistent with how an
empty array is already handled. Adds regression coverage on both the OpenID
strategy and the remote-agent API auth paths.

* refactor: Address OpenID role-sync review feedback

- role.ts: reuse the shared escapeRegExp util instead of a local escapeRegex
  duplicate, matching prompt/skill/user/userGroup methods (Copilot).
- openidStrategy.js / remoteAgentAuth.ts: make the tenantStorage.run callbacks
  async so the documented ALS contract is satisfied and tenant context cannot
  be lost during Mongoose execution; the wrapped lookups/updates are already
  async, so behavior is unchanged (codex P2).

* fix: Harden OpenID role-sync claim and fallback handling

Addresses the second Codex review cycle (P2 findings):

- Apply fallback when the claim is absent: getOpenIdRolesForOpenIdSync now
  returns an empty list (not undefined) when the token source exists but has
  no usable claim value, so callers still run selection and assign the
  configured fallback instead of leaving a stale elevated role. A truly
  unavailable source still returns undefined and skips sync.
- Resolve group overage for access tokens too: the _claim_names/_claim_sources
  overage path previously only ran for claimSource 'id'; Entra also moves an
  oversized groups claim into access tokens, so 'access'+'groups' (the only
  source supported by remote-agent API sync) now resolves overage as well.
- Allow system fallback roles for tenant users: getLibreChatRolesForOpenIdSync
  treats SystemRoles (e.g. USER) as always-available canonical names, since
  they are provisioned globally at startup and a tenant-scoped lookup may not
  return them — preventing a spurious 'configured roles do not exist: USER'.

Adds unit and strategy-level coverage for all three.

* fix: Tighten OpenID role-sync tenant scoping and config validation

Addresses the third Codex review cycle:

- Constrain base-user role lookups to base roles (P2): findRolesByNames now
  filters to roles with an unset tenantId when no tenant ALS context is active,
  so a base user cannot match — and be assigned — a role that only exists within
  a tenant. Tenant-scoped lookups remain controlled by the isolation plugin.
- Re-enforce tenant login policy after role sync (P2): when role sync changes a
  tenant user's role, the OpenID strategy re-resolves the tenant appConfig and
  re-checks allowedDomains, so a token cannot complete login under the previous
  role's looser policy.
- Skip role-sync-specific validation when disabled (P3): getOpenIdRoleSyncOptions
  returns disabled options before validating role-sync settings, so a stale or
  mistyped value no longer breaks OpenID login while the feature is off.

Adds unit and strategy-level coverage for all three.

* fix: Run base role lookups under system context for strict isolation

Follow-up to the base-role scoping fix (Codex P1). With TENANT_ISOLATION_STRICT=true,
the tenant-isolation pre('find') hook throws on a context-less query before the manual
tenantId filter is honored, so base OpenID/remote-agent auth would 500 instead of
validating base roles. findRolesByNames now runs the no-context lookup inside
runAsSystem (SYSTEM_TENANT_ID), bypassing strict-mode injection while still applying an
explicit base-role (tenantId unset) filter. Adds a strict-mode regression test.

📋 fix: Cap Default Limit on Agent List Queries (#13382)
* 🛡️ fix: Cap Default Limit on Agent List Queries (#13363)

`GET /api/agents` accepted unbounded requests: when the client omitted
`limit`, the value flowed straight into `getListAgentsByAccess`, which
set `isPaginated = false` and issued an uncapped MongoDB query. Combined
with the unindexed `findPubliclyAccessibleResources` AclEntry scan run
on every request, this produced 10-19s response times and stalled the
connection pool on instances with 100+ agents.

- Default `limit` to 100 in the route handler so client requests without
  `?limit=` paginate by default.
- Default `limit` to 100 in `getListAgentsByAccess` itself as
  defense-in-depth. The function already caps numeric limits at 100, so
  there is no client-facing change.
- Pass `limit: null` explicitly in the actions route, which legitimately
  needs the full editable-agent set, to preserve its existing behavior.
- Add regression tests covering the default cap and the explicit
  unbounded opt-out.

* 🛡️ fix: Avoid agent-list regression for users with 100+ agents

Codex review pointed out that capping `getListAgentsByAccess` at 100
silently truncated agents past the first page for the four consumers
(`useAgentsMap`, `AgentSelect`, `ModelSelectorContext`, `useMentions`)
that read `res.data` without following `has_more`/`after`.

- Raise the function's hard cap from 100 to 1000 to match
  `MAX_AVATAR_REFRESH_AGENTS`, the realistic upper bound the
  avatar-refresh path already assumes. (Side effect: the avatar refresh
  call site was silently being capped at 100 by the old normalize step.)
- In `useListAgentsQuery`, merge `limit: 1000` into params so the four
  consumers above get the user's full accessible set in a single
  round-trip instead of needing cursor pagination.
- Route handler default stays at 100 as defense-in-depth for any other
  caller that omits `limit`.
- Add a regression test asserting an explicit `limit` above 100 now
  returns the full set instead of being clipped.

* 🪢 fix: Keep agent-list cache key stable for mutations

Codex P2 review noted that folding `limit: 1000` into the cache key
broke `allAgentViewAndEditQueryKeys` in `Agents/mutations.ts`, which
references `[QueryKeys.agents, { requiredPermission }]` directly across
eight mutation handlers. After my prior change the cached entry lived
under `[QueryKeys.agents, { limit: 1000, requiredPermission }]`, so
create/update/delete/avatar/action mutations stopped updating the list
the four consumer hooks render — and with `refetchOnMount` and focus/
reconnect refetches disabled, the UI would stay stale until something
else triggered a fetch.

Split the merged limit out of the cache key: the request to
`dataService.listAgents` still uses `requestParams` (with the default
limit applied), but the React Query cache key uses the caller's `params`
as-is. The mutation cache updates land again, and the request still
returns the user's full accessible set in one round-trip.

* 🛡️ fix: Index AclEntry and paginate agent list internally (#13363)

Completes the perf fix for #13363 properly — resolves both the
unbounded ACL scans Copilot flagged and Codex's tension between "show
all agents" and "don't bypass the server cap".

Backend:
- Add a compound index on `{ principalType, resourceType, permBits,
  resourceId }` to the AclEntry schema. This is the index missing for
  `findPublicResourceIds` and the public branch of the `$or` in
  `findAccessibleResources`, both of which previously fell back to a
  collection scan on every `GET /api/agents`. Adds an `explain`-based
  regression test asserting the public query no longer COLLSCANs.

Client:
- Rewrite `useListAgentsQuery` to follow the server's cursor
  pagination internally and concatenate every page into a single flat
  `AgentListResponse`. Consumers (`useAgentsMap`, `AgentSelect`,
  `ModelSelectorContext`, `useMentions`) get the user's complete
  accessible-agent set without any of them needing to learn about
  cursors, and each individual request uses the server's default
  page size (so the route's 100-default defense-in-depth fires for
  real). Cache key shape is unchanged, so the eight mutation handlers
  in `Agents/mutations.ts` keep matching `allAgentViewAndEditQueryKeys`
  and update the cached list as before.
- Drop the `FULL_AGENT_LIST_LIMIT = 1000` injection added in the
  previous commit — no longer needed once pagination handles the full
  set, and removing it stops bypassing the route default.

* 🧹 fix: CI fallout from C-done-properly refactor

- Collapse multi-line `fetchAllAgentPages` signature in queries.ts so
  prettier stops complaining.
- In the new public-principal index test, grant one ACL entry before
  calling `.explain()` so the collection exists (otherwise mongo returns
  `nonExistentNamespace` and there is no winning plan to inspect).
- Cast the `.explain('queryPlanner')` result to a typed shape — the
  mongoose return type doesn't expose `queryPlanner` directly and was
  failing the TypeScript check.

* 🧪 fix: Test the AclEntry public-principal index via hint, not planner choice

The previous test asserted the query planner did not pick COLLSCAN for
the public-principal lookup. That assertion fails on small collections
(under the planner's collection-size heuristic) — the index exists and
is usable, but with a single document in the test the planner correctly
chooses COLLSCAN as the cheaper plan.

Reshape the assertion:
1. Confirm the new compound index is actually declared by inspecting
   `collection.indexes()` after `syncIndexes()`.
2. Force the planner to that index via `.hint()` and assert the winning
   plan is `IXSCAN` — proves the index is real and serves this query
   shape, without depending on collection-size heuristics.

* 🧹 chore: Slim down verbose comments

The JSDoc and inline comments added across the perf fix had drifted
into multi-paragraph rationale better suited to the PR description than
the source. Collapse to single-line JSDoc that just describes what each
piece does; drop the inline comment in `actions.js` entirely — the call
is self-evident.

🪟 feat: Add allowedAddresses Exemption List For SSRF-Guarded Targets (#12933)
* 🪟 feat: Add allowedAddresses Exemption List For SSRF-Guarded Targets

LibreChat already blocks SSRF-prone targets (private IPs, loopback,
link-local, .internal/.local TLDs) at every server-side fetch site
that consumes user-controllable URLs — custom-endpoint baseURLs, MCP
servers, OpenAPI Actions, and OAuth endpoints. The only existing
escape hatch is `allowedDomains`, but that flips the field into a
strict whitelist: adding `127.0.0.1` to permit a self-hosted Ollama
also blocks every public destination that isn't in the list.

Introduce `allowedAddresses` as the orthogonal primitive: a private-
IP-space exemption list. When a hostname or its resolved IP appears
in the list, the SSRF block is bypassed for that target. Public
destinations remain reachable. Operators can now run self-hosted
LLMs / MCP servers / Action endpoints on private addresses without
weakening the default-deny posture for everything else.

Schema additions in `packages/data-provider/src/config.ts`:
- `endpoints.allowedAddresses` (new — gates `validateEndpointURL`)
- `mcpSettings.allowedAddresses` (parallel to `allowedDomains`)
- `actions.allowedAddresses` (parallel to `allowedDomains`)

Core changes in `packages/api/src/auth/`:
- New `isAddressAllowed(hostnameOrIP, allowedAddresses)` — pure,
  case-insensitive, bracket-stripped literal match.
- Threaded the list through `isSSRFTarget`, `resolveHostnameSSRF`,
  `isDomainAllowedCore`, `isActionDomainAllowed`, `isMCPDomainAllowed`,
  `isOAuthUrlAllowed`, and `validateEndpointURL`.
- Extended `createSSRFSafeAgents` and `createSSRFSafeUndiciConnect`
  to accept the list, building an SSRF-safe DNS lookup that exempts
  matching hostnames/IPs at TCP connect time (TOCTOU-safe).

Wiring:
- Custom and OpenAI endpoint initialize sites pass
  `endpoints.allowedAddresses` to `validateEndpointURL`.
- `MCPServersRegistry` stores `allowedAddresses` and exposes it via
  `getAllowedAddresses()`. The factory, connection class, manager,
  `UserConnectionManager`, and `ConnectionsRepository` all thread
  it through to the SSRF utilities.
- `MCPOAuthHandler.initiateOAuthFlow`, `refreshOAuthTokens`, and
  `validateOAuthUrl` accept the list and consult it on every URL
  validation along the OAuth chain.
- `ToolService`, `ActionService`, and the assistants/agents action
  routes pass `actions.allowedAddresses` to `isActionDomainAllowed`
  and to `createSSRFSafeAgents` for runtime action calls.
- `initializeMCPs.js` reads `mcpSettings.allowedAddresses` from the
  app config and forwards it to the registry constructor.

Documentation:
- `librechat.example.yaml` shows the new field next to each existing
  `allowedDomains` block, with a note clarifying that
  `allowedAddresses` is an exemption list (not a whitelist).

Tests:
- Unit tests for `isAddressAllowed` covering literal IPs, hostnames,
  IPv6 brackets, case insensitivity, and partial-match rejection.
- Exemption tests for every entry point: `isSSRFTarget`,
  `resolveHostnameSSRF`, `validateEndpointURL`, `isActionDomainAllowed`,
  `isMCPDomainAllowed`, `isOAuthUrlAllowed`.
- Existing tests updated to reflect the new optional parameter.

Default behavior is unchanged: omitted = empty list = no exemptions.

* 🩹 fix: Plumb allowedAddresses Through AppConfig endpoints Type

The initial PR added `endpoints.allowedAddresses` to the
data-provider config schema and consumed it in the endpoint
initialize sites, but the runtime `AppConfig.endpoints` shape in
`@librechat/data-schemas` was a hand-maintained subset that didn't
include the new field — so `tsc` rejected `appConfig.endpoints.allowedAddresses`.

Add the field to `AppConfig['endpoints']` in
`packages/data-schemas/src/types/app.ts` and forward it from the
loaded config in `packages/data-schemas/src/app/endpoints.ts` so the
runtime config carries the value.

Update `initializeMCPs.spec.js` to expect the third positional
argument (`allowedAddresses`) on the `createMCPServersRegistry` call.

* 🩹 fix: Enforce allowedDomains Before allowedAddresses In isOAuthUrlAllowed

The initial implementation checked the address exemption first, so a
URL whose hostname appeared in `allowedAddresses` would return true
even when the admin had configured `allowedDomains` as a strict bound
on OAuth endpoints. A malicious MCP server could advertise OAuth
metadata, token, or revocation URLs at any address the admin had
permitted for an unrelated reason (a self-hosted LLM at `127.0.0.1`,
for example) and pass validation, expanding SSRF reach beyond the
configured domain whitelist.

Reorder: when `allowedDomains` is set, treat it as authoritative —
return true only if the URL matches a domain entry, otherwise fall
through to false. The address exemption only applies when no
`allowedDomains` is configured (mirrors how the downstream SSRF check
in `validateOAuthUrl` consults `allowedAddresses`).

Add a regression test asserting that an `allowedAddresses` entry does
not broaden a configured `allowedDomains` list.

Reported by chatgpt-codex-connector on PR #12933.

* 🩹 fix: Forward allowedAddresses To Remaining OAuth Callers

Two `MCPOAuthHandler` callers still used the pre-feature signatures and
were silently dropping the new `allowedAddresses` argument:

- `api/server/routes/mcp.js` invoked `initiateOAuthFlow` with the old
  5-argument shape, so OAuth flows initiated through the route handler
  ignored the registry's `getAllowedAddresses()` and would reject any
  metadata/authorization/token URL on a permitted private host.
- `api/server/controllers/UserController.js#maybeUninstallOAuthMCP`
  invoked `revokeOAuthToken` without the address exemption, so
  uninstalling an OAuth-backed MCP server on a permitted private host
  would fail at the revocation step even though the rest of the MCP
  connection path now permits it.

Both sites now read `allowedAddresses` from the registry alongside
`allowedDomains` and forward it. Reported by Copilot on PR #12933.

* 🩹 fix: Update Test Mocks And Assertions For OAuth allowedAddresses

The previous commit started passing `allowedAddresses` to
`MCPOAuthHandler.initiateOAuthFlow` from `api/server/routes/mcp.js`
and to `MCPOAuthHandler.revokeOAuthToken` from
`api/server/controllers/UserController.js`, but the corresponding
test files mocked the registry without `getAllowedAddresses` (causing
`TypeError`s) and asserted the old positional shape on
`toHaveBeenCalledWith`.

Update the mocks and assertions to match the new arity:

- `api/server/routes/__tests__/mcp.spec.js`: add
  `getAllowedDomains`/`getAllowedAddresses` to the registry mock and
  expect the additional positional args on `initiateOAuthFlow`.
- `api/server/controllers/__tests__/maybeUninstallOAuthMCP.spec.js`:
  add a `getAllowedAddresses` mock alongside the existing
  `getAllowedDomains` and seed it in `setupOAuthServerFound`.
- `api/server/controllers/__tests__/UserController.mcpOAuth.spec.js`:
  add `getAllowedAddresses` to the registry mock and expect the
  trailing `null` arg on the three `revokeOAuthToken` assertions.

* 🛡️ fix: Address Comprehensive Review — Scope allowedAddresses To Private IP Space

Major findings from the comprehensive PR review (severity → fix):

**CRITICAL — `validateOAuthUrl` SSRF fallback bypass.** When `allowedDomains`
is configured and a URL fails the whitelist, the SSRF fallback in
`validateOAuthUrl` was still passing `allowedAddresses` to `isSSRFTarget` /
`resolveHostnameSSRF`, letting a malicious MCP server advertise OAuth
endpoints at any address the admin had permitted for an unrelated reason.
Suppress `allowedAddresses` in the fallback when `allowedDomains` is active —
the address exemption is opt-in for the no-whitelist mode only.

**MAJOR — WebSocket transport SSRF check ignored exemptions.** The
`constructTransport` WebSocket branch called `resolveHostnameSSRF(wsHostname)`
without `this.allowedAddresses`, so a permitted private MCP server would
pass `isMCPDomainAllowed` but be blocked at transport creation. Forward
the exemption.

**Scope `allowedAddresses` to private IP space only (operator directive).**
The exemption list is for permitting private/internal targets; it must not
be a back-door to broaden trust to public destinations.
- Schema (`packages/data-provider/src/config.ts`): new
  `allowedAddressesSchema` rejects URLs (`://`), paths/CIDR (`/`),
  whitespace, and public IPv4/IPv6 literals at config-load time. Wired
  into `endpoints`, `mcpSettings`, and `actions`.
- Runtime (`packages/api/src/auth/domain.ts`): `isAddressAllowed` now
  drops public-IP candidates and public-IP entries on the match path —
  defense in depth so a misconfigured runtime list never grants exemption.
- Hot path (`packages/api/src/auth/agent.ts`): `buildSSRFSafeLookup`
  pre-normalizes the list into a `Set<string>` once at construction and
  applies the same scoping filter, so the connect-time DNS lookup is an
  O(1) Set membership check instead of a full re-iterate-and-normalize on
  every outbound request.

**Test coverage for the connect-time and OAuth-fallback paths.**
- `agent.spec.ts`: new describe block exercising `buildSSRFSafeLookup` and
  `createSSRFSafe*` with `allowedAddresses` — hostname-literal exemption,
  resolved-IP exemption, public-IP scoping, URL/CIDR/whitespace rejection,
  and the default no-list block.
- `handler.allowedAddresses.test.ts` (new): integration tests for
  `validateOAuthUrl` — covers both the no-domains-set "permit private"
  path and the strict-bound regression where `allowedAddresses` must NOT
  bypass `allowedDomains`.

**Documentation & cleanup.**
- `connection.ts` redirect SSRF check: explicit comment that
  `allowedAddresses` is intentionally NOT consulted for redirect targets
  (server-controlled, must not inherit the admin's exemption).
- `MCPConnectionFactory.test.ts`: replaced an `eslint-disable` with a
  proper `import { getTenantId } from '@librechat/data-schemas'`. The
  disable was added to make a pre-existing `require()` quiet — the cleaner
  fix is to use the existing top-level import.

Updated `MCPConnectionSSRF.test.ts` WebSocket SSRF assertions to match the
new two-argument call shape (`hostname, allowedAddresses`).

* 🩹 fix: Require Absolute URL Before allowedAddresses Trust Bypass In isOAuthUrlAllowed

`parseDomainSpec` is lenient — it silently prepends `https://` to
schemeless inputs so it can match patterns like bare `example.com`.
That leniency leaked into `isOAuthUrlAllowed`'s new
`allowedAddresses` short-circuit: a value like `10.0.0.5/oauth` (no
scheme) would parse successfully via the prepended default, hit the
address-exemption path, return `true`, and skip `validateOAuthUrl`'s
strict `new URL(url)` parse-or-throw — only to fail later in OAuth
discovery with a less clear runtime error.

Add a strict `new URL(url)` gate at the top of `isOAuthUrlAllowed`.
Schemeless inputs now fall through to `validateOAuthUrl`'s explicit
"Invalid OAuth <field>" rejection. Tests added in both
`auth/domain.spec.ts` (unit) and the OAuth handler integration spec
(end-to-end).

Reported by chatgpt-codex-connector (P2) on PR #12933.

* 🛡️ fix: Address Follow-Up Comprehensive Review — Schema Tests, Shared Normalization, host:port

Auditing the second comprehensive review:

**F1 MAJOR — schema validation untested.** `allowedAddressesSchema` had
zero coverage, so a regression in the three refinement stages or the
three wiring locations (`endpoints` / `mcpSettings` / `actions`) would
silently let invalid entries reach the runtime. Added a dedicated
`describe('allowedAddressesSchema')` block in `config.spec.ts` covering:
valid private IPs (v4 + v6, including the previously-missed 192.0.0.0/24
range), accepted hostnames, all rejection categories (URLs, CIDR, paths,
whitespace tabs/newlines, host:port, public IP literals), and full
`configSchema.parse()` integration at each of the three nesting points.

**F2 MINOR — `isPrivateIPv4Literal` divergence.** The schema reimpl in
`packages/data-provider` was discarding the `c` octet, so the
`192.0.0.0/24` (RFC 5736 IETF protocol assignments) range that the
authoritative `isPrivateIPv4` accepts was being rejected with a
misleading "public IP" error. Destructure `c` and add the missing range
check; covered by the new schema tests.

**F3 MINOR — DRY violation across `domain.ts` and `agent.ts`.** Both
files had independent normalization implementations with a subtle
whitespace-check divergence (`/\s/` vs `.includes(' ')`). Extracted the
shared logic into a new `packages/api/src/auth/allowedAddresses.ts`
module that both consumers import:
  - `normalizeAddressEntry(entry)` — single-entry shape check
  - `looksLikeHostPort(entry)` — host:port detector (used by F4)
  - `normalizeAllowedAddressesSet(list)` — pre-normalized Set for the
    connect-time hot path
  - `isAddressInAllowedSet(candidate, set)` — membership check that
    enforces private-IP scoping on the candidate

Both `isAddressAllowed` (preflight) and `buildSSRFSafeLookup` (connect)
now go through the same primitives; the whitespace divergence is gone.

To break the import cycle (`allowedAddresses` needs `isPrivateIP`,
`domain` previously owned it), extracted IP private-range detection
into a leaf `auth/ip.ts` module. `domain.ts` re-exports `isPrivateIP`
for backward compatibility with existing call sites.

**F4 MINOR — `host:port` silently misclassified.** Entries like
`localhost:8080` previously slipped through the URL/path guard, were
mis-detected as IPv6, failed `isPrivateIP`, and were silently dropped
with a misleading "public IP" schema error. Added an explicit
`looksLikeHostPort` check with a clear error: "allowedAddresses
entries must not include a port — list the bare hostname or IP only."
Bare `::1`, `[::1]`, and other valid IPv6 literals are intentionally
not matched (regex distinguishes by colon count and the bracketed
`[ipv6]:port` form).

**F5 MINOR — hostname-trust documentation gap.** Hostname entries
short-circuit `resolveHostnameSSRF` before any DNS lookup — that's a
deliberate design (admin trusts the name) but it means the exemption
follows whatever the name resolves to at runtime. Added an explicit
note in `librechat.example.yaml` for both `mcpSettings.allowedAddresses`
and `endpoints.allowedAddresses`: "a hostname entry trusts whatever IP
that name resolves to. Only list hostnames whose DNS you control.
Prefer literal IPs when you can."

**F6** (8 positional params) is flagged for follow-up; refactor to an
options object is a breaking-API change deferred to a separate PR.
**F7** (redirect/WebSocket asymmetry, NIT, conf 40) — skipping; the
existing inline comment is sufficient.

* 🧹 chore: Address Follow-Up NITs — Import Order And Mirror-Function Naming

Three NITs from the latest comprehensive review:

**NIT #1 (conf 85) — local import order.** AGENTS.md requires local
imports sorted longest-to-shortest. Both `domain.ts` and `agent.ts`
had `./ip` (shorter) before `./allowedAddresses` (longer). Swapped.

**NIT #2 (conf 60) — missing cross-reference.** The schema-side
`isHostPortShape` in `packages/data-provider/src/config.ts` had no
note pointing at the canonical runtime mirror. Added a JSDoc paragraph
explaining the mirror relationship and why a local copy exists (the
data-provider package can't import from `@librechat/api` without
creating a circular dependency).

**NIT #3 (conf 50) — naming inconsistency.** Renamed
`isHostPortShape` → `looksLikeHostPort` so the schema mirror matches
the runtime helper exactly. Kept as a separate function (not a shared
import) for the same circular-dependency reason; the matching name
makes it obvious they should stay in lockstep.

🩹 fix(SSE): Treat responseCode === 0 as Transport Failure, Not Server Error (#12834)
* fix(sse): treat responseCode===0 as transport failure, not server error

When a long-running model response (e.g. gpt-5.4 with web_search:true)
takes longer than the browser's idle connection timeout, the SSE transport
drops and sse.js fires an error event with responseCode=0 and e.data set
to the raw response buffer (non-JSON SSE text).

The previous guard `!responseCode` is truthy for both 0 (transport drop)
and undefined (genuine server-sent error event), so the client incorrectly
entered the server-error branch, tried to JSON.parse raw SSE text, logged
"Failed to parse server error", and showed the user a red error banner --
even though the backend continued processing and delivered the final answer
seconds later.

Fix 1 (client): change guard from `!responseCode` to `responseCode == null`
so that only undefined/null (no HTTP status at all) triggers the server-error
parse path. responseCode===0 now correctly falls through to the reconnect path.

Fix 2 (backend): after res.flushHeaders() the response is already committed
as SSE. The fallback branch that wrote res.status(404).json() was an HTTP/SSE
protocol violation. Replace with an SSE-conformant event:error frame + res.end().

* fix(sse): use onError helper on subscribe failure + add regression tests

Replace silent res.end() with onError('Failed to subscribe to stream')
so the client receives a parseable SSE error event instead of a stream
that closes with no signal. The previous res.end() left the UI stuck
in "submitting" state because no error/abort/final event ever fired.

Also adds two missing test cases for the responseCode guard change:
- responseCode === 0 with raw SSE buffer data must NOT call errorHandler
  (transport failure should reconnect, not display garbage)
- responseCode == null with JSON error data MUST call errorHandler
  (server-sent error events should still surface to the user)

🏗️ feat: bulkWrite isolation, pre-auth context, strict-mode fixes (#12445)
* fix: wrap seedDatabase() in runAsSystem() for strict tenant mode

seedDatabase() was called without tenant context at startup, causing
every Mongoose operation inside it to throw when
TENANT_ISOLATION_STRICT=true. Wrapping in runAsSystem() gives it the
SYSTEM_TENANT_ID sentinel so the isolation plugin skips filtering,
matching the pattern already used for performStartupChecks and
updateInterfacePermissions.

* fix: chain tenantContextMiddleware in optionalJwtAuth

optionalJwtAuth populated req.user but never established ALS tenant
context, unlike requireJwtAuth which chains tenantContextMiddleware
after successful auth. Authenticated users hitting routes with
optionalJwtAuth (e.g. /api/banner) had no tenant isolation.

* feat: tenant-safe bulkWrite wrapper and call-site migration

Mongoose's bulkWrite() does not trigger schema-level middleware hooks,
so the applyTenantIsolation plugin cannot intercept it. This adds a
tenantSafeBulkWrite() utility that injects the current ALS tenant
context into every operation's filter/document before delegating to
native bulkWrite.

Migrates all 8 runtime bulkWrite call sites:
- agentCategory (seedCategories, ensureDefaultCategories)
- conversation (bulkSaveConvos)
- message (bulkSaveMessages)
- file (batchUpdateFiles)
- conversationTag (updateTagsForConversation, bulkIncrementTagCounts)
- aclEntry (bulkWriteAclEntries)

systemGrant.seedSystemGrants is intentionally not migrated — it uses
explicit tenantId: { $exists: false } filters and is exempt from the
isolation plugin.

* feat: pre-auth tenant middleware and tenant-scoped config cache

Adds preAuthTenantMiddleware that reads X-Tenant-Id from the request
header and wraps downstream in tenantStorage ALS context. Wired onto
/oauth, /api/auth, /api/config, and /api/share — unauthenticated
routes that need tenant scoping before JWT auth runs.

The /api/config cache key is now tenant-scoped
(STARTUP_CONFIG:${tenantId}) so multi-tenant deployments serve the
correct login page config per tenant.

The middleware is intentionally minimal — no subdomain parsing, no
OIDC claim extraction. The private fork's reverse proxy or auth
gateway sets the header.

* feat: accept optional tenantId in updateInterfacePermissions

When tenantId is provided, the function re-enters inside
tenantStorage.run({ tenantId }) so all downstream Mongoose queries
target that tenant's roles instead of the system context. This lets
the private fork's tenant provisioning flow call
updateInterfacePermissions per-tenant after creating tenant-scoped
ADMIN/USER roles.

* fix: tenant-filter $lookup in getPromptGroup aggregation

The $lookup stage in getPromptGroup() queried the prompts collection
without tenant filtering. While the outer PromptGroup aggregate is
protected by the tenantIsolation plugin's pre('aggregate') hook,
$lookup runs as an internal MongoDB operation that bypasses Mongoose
hooks entirely.

Converts from simple field-based $lookup to pipeline-based $lookup
with an explicit tenantId match when tenant context is active.

* fix: replace field-level unique indexes with tenant-scoped compounds

Field-level unique:true creates a globally-unique single-field index in
MongoDB, which would cause insert failures across tenants sharing the
same ID values.

- agent.id: removed field-level unique, added { id, tenantId } compound
- convo.conversationId: removed field-level unique (compound at line 50
  already exists: { conversationId, user, tenantId })
- message.messageId: removed field-level unique (compound at line 165
  already exists: { messageId, user, tenantId })
- preset.presetId: removed field-level unique, added { presetId, tenantId }
  compound

* fix: scope MODELS_CONFIG, ENDPOINT_CONFIG, PLUGINS, TOOLS caches by tenant

These caches store per-tenant configuration (available models, endpoint
settings, plugin availability, tool definitions) but were using global
cache keys. In multi-tenant mode, one tenant's cached config would be
served to all tenants.

Appends :${tenantId} to cache keys when tenant context is active.
Falls back to the unscoped key when no tenant context exists (backward
compatible for single-tenant OSS deployments).

Covers all read, write, and delete sites:
- ModelController.js: get/set MODELS_CONFIG
- PluginController.js: get/set PLUGINS, get/set TOOLS
- getEndpointsConfig.js: get/set/delete ENDPOINT_CONFIG
- app.js: delete ENDPOINT_CONFIG (clearEndpointConfigCache)
- mcp.js: delete TOOLS (updateMCPTools, mergeAppTools)
- importers.js: get ENDPOINT_CONFIG

* fix: add getTenantId to PluginController spec mock

The data-schemas mock was missing getTenantId, causing all
PluginController tests to throw when the controller calls
getTenantId() for tenant-scoped cache keys.

* fix: address review findings — migration, strict-mode, DRY, types

Addresses all CRITICAL, MAJOR, and MINOR review findings:

F1 (CRITICAL): Add agents, conversations, messages, presets to
SUPERSEDED_INDEXES in tenantIndexes.ts so dropSupersededTenantIndexes()
drops the old single-field unique indexes that block multi-tenant inserts.

F2 (CRITICAL): Unknown bulkWrite op types now throw in strict mode
instead of silently passing through without tenant injection.

F3 (MAJOR): Replace wildcard export with named export for
tenantSafeBulkWrite, hiding _resetBulkWriteStrictCache from the
public package API.

F5 (MAJOR): Restore AnyBulkWriteOperation<IAclEntry>[] typing on
bulkWriteAclEntries — the unparameterized wrapper accepts parameterized
ops as a subtype.

F7 (MAJOR): Fix config.js tenant precedence — JWT-derived
req.user.tenantId now takes priority over the X-Tenant-Id header for
authenticated requests.

F8 (MINOR): Extract scopedCacheKey() helper into tenantContext.ts and
replace all 11 inline occurrences across 7 files.

F9 (MINOR): Use simple localField/foreignField $lookup for the
non-tenant getPromptGroup path (more efficient index seeks).

F12 (NIT): Remove redundant BulkOp type alias.
F13 (NIT): Remove debug log that leaked raw tenantId.

* fix: add new superseded indexes to tenantIndexes test fixture

The test creates old indexes to verify the migration drops them.
Missing fixture entries for agents.id_1, conversations.conversationId_1,
messages.messageId_1, and presets.presetId_1 caused the count assertion
to fail (expected 22, got 18).

* fix: restore logger.warn for unknown bulk op types in non-strict mode

* fix: block SYSTEM_TENANT_ID sentinel from external header input

CRITICAL: preAuthTenantMiddleware accepted any string as X-Tenant-Id,
including '__SYSTEM__'. The tenantIsolation plugin treats SYSTEM_TENANT_ID
as an explicit bypass — skipping ALL query filters. A client sending
X-Tenant-Id: __SYSTEM__ to pre-auth routes (/api/share, /api/config,
/api/auth, /oauth) would execute Mongoose operations without tenant
isolation.

Fixes:
- preAuthTenantMiddleware rejects SYSTEM_TENANT_ID in header
- scopedCacheKey returns the base key (not key:__SYSTEM__) in system
  context, preventing stale cache entries during runAsSystem()
- updateInterfacePermissions guards tenantId against SYSTEM_TENANT_ID
- $lookup pipeline separates $expr join from constant tenantId match
  for better index utilization
- Regression test for sentinel rejection in preAuthTenant.spec.ts
- Remove redundant getTenantId() call in config.js

* test: add missing deleteMany/replaceOne coverage, fix vacuous ALS assertions

bulkWrite spec:
- deleteMany: verifies tenant-scoped deletion leaves other tenants untouched
- replaceOne: verifies tenantId injected into both filter and replacement
- replaceOne overwrite: verifies a conflicting tenantId in the replacement
  document is overwritten by the ALS tenant (defense-in-depth)
- empty ops array: verifies graceful handling

preAuthTenant spec:
- All negative-case tests now use the capturedNext pattern to verify
  getTenantId() inside the middleware's execution context, not the
  test runner's outer frame (which was always undefined regardless)

* feat: tenant-isolate MESSAGES cache, FLOWS cache, and GenerationJobManager

MESSAGES cache (streamAudio.js):
- Cache key now uses scopedCacheKey(messageId) to prefix with tenantId,
  preventing cross-tenant message content reads during TTS streaming.

FLOWS cache (FlowStateManager):
- getFlowKey() now generates ${type}:${tenantId}:${flowId} when tenant
  context is active, isolating OAuth flow state per tenant.

GenerationJobManager:
- tenantId added to SerializableJobData and GenerationJobMetadata
- createJob() captures the current ALS tenant context (excluding
  SYSTEM_TENANT_ID) and stores it in job metadata
- SSE subscription endpoint validates job.metadata.tenantId matches
  req.user.tenantId, blocking cross-tenant stream access
- Both InMemoryJobStore and RedisJobStore updated to accept tenantId

* fix: add getTenantId and SYSTEM_TENANT_ID to MCP OAuth test mocks

FlowStateManager.getFlowKey() now calls getTenantId() for tenant-scoped
flow keys. The 4 MCP OAuth test files mock @librechat/data-schemas
without these exports, causing TypeError at runtime.

* fix: correct import ordering per AGENTS.md conventions

Package imports sorted shortest to longest line length, local imports
sorted longest to shortest — fixes ordering violations introduced by
our new imports across 8 files.

* fix: deserialize tenantId in RedisJobStore — cross-tenant SSE guard was no-op in Redis mode

serializeJob() writes tenantId to the Redis hash via Object.entries,
but deserializeJob() manually enumerates fields and omitted tenantId.
Every getJob() from Redis returned tenantId: undefined, causing the
SSE route's cross-tenant guard to short-circuit (undefined && ... → false).

* test: SSE tenant guard, FlowStateManager key consistency, ALS scope docs

SSE stream tenant tests (streamTenant.spec.js):
- Cross-tenant user accessing another tenant's stream → 403
- Same-tenant user accessing own stream → allowed
- OSS mode (no tenantId on job) → tenant check skipped

FlowStateManager tenant tests (manager.tenant.spec.ts):
- completeFlow finds flow created under same tenant context
- completeFlow does NOT find flow under different tenant context
- Unscoped flows are separate from tenant-scoped flows

Documentation:
- JSDoc on getFlowKey documenting ALS context consistency requirement
- Comment on streamAudio.js scopedCacheKey capture site

* fix: SSE stream tests hang on success path, remove internal fork references

The success-path tests entered the SSE streaming code which never
closes, causing timeout. Mock subscribe() to end the response
immediately. Restructured assertions to verify non-403/non-404.

Removed "private fork" and "OSS" references from code and test
descriptions — replaced with "deployment layer", "multi-tenant
deployments", and "single-tenant mode".

* fix: address review findings — test rigor, tenant ID validation, docs

F1: SSE stream tests now mock subscribe() with correct signature
(streamId, writeEvent, onDone, onError) and assert 200 status,
verifying the tenant guard actually allows through same-tenant users.

F2: completeFlow logs the attempted key and ALS tenantId when flow
is not found, so reverse proxy misconfiguration (missing X-Tenant-Id
on OAuth callback) produces an actionable warning.

F3/F10: preAuthTenantMiddleware validates tenant ID format — rejects
colons, special characters, and values exceeding 128 chars. Trims
whitespace. Prevents cache key collisions via crafted headers.

F4: Documented cache invalidation scope limitation in
clearEndpointConfigCache — only the calling tenant's key is cleared;
other tenants expire via TTL.

F7: getFlowKey JSDoc now lists all 8 methods requiring consistent
ALS context.

F8: Added dedicated scopedCacheKey unit tests — base key without
context, base key in system context, scoped key with tenant, no
ALS leakage across scope boundaries.

* fix: revert flow key tenant scoping, fix SSE test timing

FlowStateManager: Reverts tenant-scoped flow keys. OAuth callbacks
arrive without tenant ALS context (provider redirects don't carry
X-Tenant-Id), so completeFlow/failFlow would never find flows
created under tenant context. Flow IDs are random UUIDs with no
collision risk, and flow data is ephemeral (TTL-bounded).

SSE tests: Use process.nextTick for onDone callback so Express
response headers are flushed before res.write/res.end are called.

* fix: restore getTenantId import for completeFlow diagnostic log

* fix: correct completeFlow warning message, add missing flow test

The warning referenced X-Tenant-Id header consistency which was only
relevant when flow keys were tenant-scoped (since reverted). Updated
to list actual causes: TTL expiry, missing flow, or routing to a
different instance without shared Keyv storage.

Removed the getTenantId() call and import — no longer needed since
flow keys are unscoped.

Added test for the !flowState branch in completeFlow — verifies
return false and logger.warn on nonexistent flow ID.

* fix: add explicit return type to recursive updateInterfacePermissions

The recursive call (tenantId branch calls itself without tenantId)
causes TypeScript to infer circular return type 'any'. Adding
explicit Promise<void> satisfies the rollup typescript plugin.

* fix: update MCPOAuthRaceCondition test to match new completeFlow warning

* fix: clearEndpointConfigCache deletes both scoped and unscoped keys

Unauthenticated /api/endpoints requests populate the unscoped
ENDPOINT_CONFIG key. Admin config mutations clear only the
tenant-scoped key, leaving the unscoped entry stale indefinitely.
Now deletes both when in tenant context.

* fix: tenant guard on abort/status endpoints, warn logs, test coverage

F1: Add tenant guard to /chat/status/:conversationId and /chat/abort
matching the existing guard on /chat/stream/:streamId. The status
endpoint exposes aggregatedContent (AI response text) which requires
tenant-level access control.

F2: preAuthTenantMiddleware now logs warn for rejected __SYSTEM__
sentinel and malformed tenant IDs, providing observability for
bypass probing attempts.

F3: Abort fallback path (getActiveJobIdsForUser) now has tenant
check after resolving the job.

F4: Test for strict mode + SYSTEM_TENANT_ID — verifies runAsSystem
bypasses tenantSafeBulkWrite without throwing in strict mode.

F5: Test for job with tenantId + user without tenantId → 403.

F10: Regex uses idiomatic hyphen-at-start form.

F11: Test descriptions changed from "rejects" to "ignores" since
middleware calls next() (not 4xx).

Also fixes MCPOAuthRaceCondition test assertion to match updated
completeFlow warning message.

* fix: test coverage for logger.warn, status/abort guards, consistency

A: preAuthTenant spec now mocks logger and asserts warn calls for
__SYSTEM__ sentinel, malformed characters, and oversized headers.

B: streamTenant spec expanded with status and abort endpoint tests —
cross-tenant status returns 403, same-tenant returns 200 with body,
cross-tenant abort returns 403.

C: Abort endpoint uses req.user.tenantId (not req.user?.tenantId)
matching stream/status pattern — requireJwtAuth guarantees req.user.

D: Malformed header warning now includes ip in log metadata,
matching the sentinel warning for consistent SOC correlation.

* fix: assert ip field in malformed header warn tests

* fix: parallelize cache deletes, document tenant guard, fix import order

- clearEndpointConfigCache uses Promise.all for independent cache
  deletes instead of sequential awaits
- SSE stream tenant guard has inline comment explaining backward-compat
  behavior for untenanted legacy jobs
- conversation.ts local imports reordered longest-to-shortest per
  AGENTS.md

* fix: tenant-qualify userJobs keys, document tenant guard backward-compat

Job store userJobs keys now include tenantId when available:
- Redis: stream:user:{tenantId:userId}:jobs (falls back to
  stream:user:{userId}:jobs when no tenant)
- InMemory: composite key tenantId:userId in userJobMap

getActiveJobIdsByUser/getActiveJobIdsForUser accept optional tenantId
parameter, threaded through from req.user.tenantId at all call sites
(/chat/active and /chat/abort fallback).

Added inline comments on all three SSE tenant guards explaining the
backward-compat design: untenanted legacy jobs remain accessible
when the userId check passes.

* fix: parallelize cache deletes, document tenant guard, fix import order

Fix InMemoryJobStore.getActiveJobIdsByUser empty-set cleanup to use
the tenant-qualified userKey instead of bare userId — prevents
orphaned empty Sets accumulating in userJobMap for multi-tenant users.

Document cross-tenant staleness in clearEndpointConfigCache JSDoc —
other tenants' scoped keys expire via TTL, not active invalidation.

* fix: cleanup userJobMap leak, startup warning, DRY tenant guard, docs

F1: InMemoryJobStore.cleanup() now removes entries from userJobMap
before calling deleteJob, preventing orphaned empty Sets from
accumulating with tenant-qualified composite keys.

F2: Startup warning when TENANT_ISOLATION_STRICT is active — reminds
operators to configure reverse proxy to control X-Tenant-Id header.

F3: mergeAppTools JSDoc documents that tenant-scoped TOOLS keys are
not actively invalidated (matching clearEndpointConfigCache pattern).

F5: Abort handler getActiveJobIdsForUser call uses req.user.tenantId
(not req.user?.tenantId) — consistent with stream/status handlers.

F6: updateInterfacePermissions JSDoc clarifies SYSTEM_TENANT_ID
behavior — falls through to caller's ALS context.

F7: Extracted hasTenantMismatch() helper, replacing three identical
inline tenant guard blocks across stream/status/abort endpoints.

F9: scopedCacheKey JSDoc documents both passthrough cases (no context
and SYSTEM_TENANT_ID context).

* fix: clean userJobMap in evictOldest — same leak as cleanup()

🪢 fix: Action Domain Encoding Collision for HTTPS URLs (#12271)
* fix: strip protocol from domain before encoding in `domainParser`

All https:// (and http://) domains produced the same 10-char base64
prefix due to ENCODED_DOMAIN_LENGTH truncation, causing tool name
collisions for agents with multiple actions.

Strip the protocol before encoding so the base64 key is derived from
the hostname. Add `legacyDomainEncode` to preserve the old encoding
logic for backward-compatible matching of existing stored actions.

* fix: backward-compatible tool matching in ToolService

Update `getActionToolDefinitions` to match stored tools against both
new and legacy domain encodings. Update `loadActionToolsForExecution`
to resolve model-called tool names via a `normalizedToDomain` map
that includes both encoding variants, with legacy fallback for
request builder lookup.

* fix: action route save/delete domain encoding issues

Save routes now remove old tools matching either new or legacy domain
encoding, preventing stale entries when an action's encoding changes
on update.

Delete routes no longer re-encode the already-encoded domain extracted
from the stored actions array, which was producing incorrect keys and
leaving orphaned tools.

* test: comprehensive coverage for action domain encoding

Rewrite ActionService tests to cover real matching patterns used by
ToolService and action routes. Tests verify encode/decode round-trips,
protocol stripping, backward-compatible tool name matching at both
definition and execution phases, save-route cleanup of old/new
encodings, delete-route domain extraction, and the collision fix for
multi-action agents.

* fix: add legacy domain compat to all execution paths, make legacyDomainEncode sync

CRITICAL: processRequiredActions (assistants path) was not updated with
legacy domain matching — existing assistants with https:// domain actions
would silently fail post-deployment because domainMap only had new encoding.

MAJOR: loadAgentTools definitionsOnly=false path had the same issue.

Both now use a normalizedToDomain map with legacy+new entries and extract
function names via the matched key (not the canonical domain).

Also: make legacyDomainEncode synchronous (no async operations), store
legacyNormalized in processedActionSets to eliminate recomputation in
the per-tool fallback, and hoist domainSeparatorRegex to module level.

* refactor: clarify domain variable naming and tool-filter helpers in action routes

Rename shadowed 'domain' to 'encodedDomain' to separate raw URL from
encoded key in both agent and assistant save routes.

Rename shouldRemoveTool to shouldRemoveAgentTool / shouldRemoveAssistantTool
to make the distinct data-shape guards explicit.

Remove await on now-synchronous legacyDomainEncode.

* test: expand coverage for all review findings

- Add validateAndUpdateTool tests (protocol-stripping match logic)
- Restore unicode domain encode/decode/round-trip tests
- Add processRequiredActions matching pattern tests (assistants path)
- Add legacy guard skip test for short bare hostnames
- Add pre-normalized Set test for definition-phase optimization
- Fix corrupt-cache test to assert typeof instead of toBeDefined
- Verify legacyDomainEncode is synchronous (not a Promise)
- Remove all await on legacyDomainEncode (now sync)

58 tests, up from 44.

* fix: address follow-up review findings A-E

A: Fix stale JSDoc @returns {Promise<string>} on now-synchronous
   legacyDomainEncode — changed to @returns {string}.

B: Rename normalizedToDomain to domainLookupMap in processRequiredActions
   and loadAgentTools where keys are raw encoded domains (not normalized),
   avoiding confusion with loadActionToolsForExecution where keys ARE
   normalized.

C: Pre-normalize actionToolNames into a Set<string> in
   getActionToolDefinitions, replacing O(signatures × tools) per-check
   .some() + .replace() with O(1) Set.has() lookups.

D: Remove stripProtocol from ActionService exports — it is a one-line
   internal helper. Spec tests for it removed; behavior is fully covered
   by domainParser protocol-stripping tests.

E: Fix pre-existing bug where processRequiredActions re-loaded action
   sets on every missing-tool iteration. The guard !actionSets.length
   always re-triggered because actionSets was reassigned to a plain
   object (whose .length is undefined). Replaced with a null-check
   on a dedicated actionSetsData variable.

* fix: strip path and query from domain URLs in stripProtocol

URLs like 'https://api.example.com/v1/endpoint?foo=bar' previously
retained the path after protocol stripping, contaminating the encoded
domain key. Now strips everything after the first '/' following the
host, using string indexing instead of URL parsing to avoid punycode
normalization of unicode hostnames.

Closes Copilot review comments 1, 2, and 5.

🛡️ refactor: Scope Action Mutations by Parent Resource Ownership (#12237)
* 🛡️ fix: Scope action mutations by parent resource ownership

Prevent cross-tenant action overwrites by validating that an existing
action's agent_id/assistant_id matches the URL parameter before allowing
updates or deletes. Without this, a user with EDIT access on their own
agent could reference a foreign action_id to hijack another agent's
action record.

* 🛡️ fix: Harden action ownership checks and scope write filters

- Remove && short-circuit that bypassed the guard when agent_id or
  assistant_id was falsy (e.g. assistant-owned actions have no agent_id,
  so the check was skipped entirely on the agents route).
- Include agent_id / assistant_id in the updateAction and deleteAction
  query filters so the DB write itself enforces ownership atomically.
- Log a warning when deleteAction returns null (silent no-op from
  data-integrity mismatch).

* 📝 docs: Update Action model JSDoc to reflect scoped query params

* ✅ test: Add Action ownership scoping tests

Cover update, delete, and cross-type protection scenarios using
MongoMemoryServer to verify that scoped query filters (agent_id,
assistant_id) prevent cross-tenant overwrites and deletions at the
database level.

* 🛡️ fix: Scope updateAction filter in agent duplication handler

* 🐛 fix: Use action metadata domain instead of action_id when duplicating agent actions

The duplicate handler was splitting `action.action_id` by `actionDelimiter`
to extract the domain, but `action_id` is a bare nanoid that doesn't
contain the delimiter. This produced malformed entries in the duplicated
agent's actions array (nanoid_action_newNanoid instead of
domain_action_newNanoid). The domain is available on `action.metadata.domain`.

* ✅ test: Add integration tests for agent duplication action handling

Uses MongoMemoryServer with real Agent and Action models to verify:
- Duplicated actions use metadata.domain (not action_id) for the
  agent actions array entries
- Sensitive metadata fields are stripped from duplicated actions
- Original action documents are not modified

🌊 fix: Prevent Buffered Event Duplication on SSE Resume Connections (#12225)
* fix: skipBufferReplay for job resume connections

- Introduced a new option `skipBufferReplay` in the `subscribe` method of `GenerationJobManagerClass` to prevent duplication of events when resuming a connection.
- Updated the logic to conditionally skip replaying buffered events if a sync event has already been sent, enhancing the efficiency of event handling during reconnections.
- Added integration tests to verify the correct behavior of the new option, ensuring that no buffered events are replayed when `skipBufferReplay` is true, while still allowing for normal replay behavior when false.

* refactor: Update GenerationJobManager to handle sync events more efficiently

- Modified the `subscribe` method to utilize a new `skipBufferReplay` option, allowing for the prevention of duplicate events during resume connections.
- Enhanced the logic in the `chat/stream` route to conditionally skip replaying buffered events if a sync event has already been sent, improving event handling efficiency.
- Updated integration tests to verify the correct behavior of the new option, ensuring that no buffered events are replayed when `skipBufferReplay` is true, while maintaining normal replay behavior when false.

* test: Enhance GenerationJobManager integration tests for Redis mode

- Updated integration tests to conditionally run based on the USE_REDIS environment variable, allowing for better control over Redis-related tests.
- Refactored test descriptions to utilize a dynamic `describeRedis` function, improving clarity and organization of tests related to Redis functionality.
- Removed redundant checks for Redis availability within individual tests, streamlining the test logic and enhancing readability.

* fix: sync handler state for new messages on resume

The sync event's else branch (new response message) was missing
resetContentHandler() and syncStepMessage() calls, leaving stale
handler state that caused subsequent deltas to build on partial
content instead of the synced aggregatedContent.

* feat: atomic subscribeWithResume to close resume event gap

Replaces separate getResumeState() + subscribe() calls with a single
subscribeWithResume() that atomically drains earlyEventBuffer between
the resume snapshot and the subscribe. In in-memory mode, drained events
are returned as pendingEvents for the client to replay after sync.
In Redis mode, pendingEvents is empty since chunks are already persisted.

The route handler now uses the atomic method for resume connections and
extracted shared SSE write helpers to reduce duplication. The client
replays any pendingEvents through the existing step/content handlers
after applying aggregatedContent from the sync payload.

* fix: only capture gap events in subscribeWithResume, not pre-snapshot buffer

The previous implementation drained the entire earlyEventBuffer into
pendingEvents, but pre-snapshot events are already reflected in
aggregatedContent. Replaying them re-introduced the duplication bug
through a different vector.

Now records buffer length before getResumeState() and slices from that
index, so only events arriving during the async gap are returned as
pendingEvents.

Also:
- Handle pendingEvents when resumeState is null (replay directly)
- Hoist duplicate test helpers to shared scope
- Remove redundant writableEnded guard in onDone
