* 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: Preemptive Steer - Backend Interrupt & Steer (#14518)
* 🛑 feat: Preemptive Steer — server half (Interrupt & Steer, PR 2 of 3)

Lets the steer route ask the generating replica to seal its live model
stream at the next provider-safe boundary instead of waiting for a tool
step. The run is never aborted, job status never changes, the partial
answer is kept, and generation resumes in the same assistant message
after the injected steer. Consumes the SDK seam in @librechat/agents
(danny-avila/agents#335, #346).

Transport: IEventTransport gains a fenced emitPreempt/onPreempt pair
beside abort. RedisEventTransport fans PREEMPT out on the SAME events
channel and subscription (no new connection, key, or subscribe call);
onPreempt returns a registration-scoped unsubscribe with the same
replacement-safe state-identity guard onAbort uses. InMemory implements
neither — single-process preempt lives entirely in the runtime set.

Runtime state: RuntimeJobState carries the per-generation request set,
createdAt-fenced and capped at STEER_QUEUE_MAX_DEPTH, plus a bounded
`cleared` tombstone so a late cross-replica arm cannot resurrect a
request whose steer already drained. registerPreemptSubscription
mirrors the abort registration's double fence (runtime identity +
generation createdAt); releaseAbortSubscription retires BOTH listeners
and the armed set, so every terminal path drops preempt state for free.
Public surface: requestPreempt (arm + fenced publish, never a rejection
surface, never touches job status), isPreemptRequested (O(1)
level-triggered poll), noteSteersRemoved (drain/cancel bookkeeping +
fenced clear), clearPreemptRequests (empty-boundary disarm).

One drain body, two boundaries: createSteerDrainHook (PostToolBatch)
and createSteerPreemptBoundaryHook (PreemptBoundary) share
drainAndBuildInjections, so the two injection sites cannot drift — the
SDK's provider-safety argument rests on identical HumanMessage shapes.
The shared body builds injections incrementally under a swallow-all
catch (a mid-loop throw still injects what was applied — those parts
are already persisted), clears preempt requests in finally, and
disarms the generation when a boundary drains nothing.

Request path: POST /chat/steer accepts preempt: true. The guard ladder
is unchanged in order and in every status code. A preempt request is
NEVER a rejection reason — without the capability the steer still
enqueues and the 202 echoes preempt: false. Armed strictly after a
successful enqueue; cancel disarms. The capability is read from the
OWNING replica's recorded `preemptCapable` rather than the route
replica's own SDK probe, so a rolling deploy cannot label a steer
"interrupting" that the older owner will only inject at a tool step.

Durable label: SteerQueueItem.preempt → TPendingSteer.preempt, so a
parked/claimed/replayed chip keeps its wording.

Run wiring: createRun registers the PreemptBoundary hook and threads
RunConfig.preemption, both gated on isSteerPreemptSupported() — a
separate probe from isSteeringSupported(), so the client affordance can
never arm against an SDK that only injects at tool boundaries.
buildSteerWiring builds both hooks from one shared closures object, so
preemption survives HITL pause/resume for free.

Honest finalization: an empty preempt boundary persists and emits with
unfinished: true — the same contract an abort gets — re-marked
explicitly because BaseClient has already saved the row as
unfinished: false by that point.

Not changed: no new job status, store method, Lua, SSE event type,
endpoint, or authorization surface. abortJob, completeJob,
transitionStatus, closeAndDrainSteers, getResumeState, emitChunk,
applySteerPart and the whole abort path are untouched.

Tests: 120 packages/api steering specs (preempt lifecycle, tombstone,
fences, caps, terminal release, both-boundary drain parity,
level-triggered poll, request/cancel arming, owner-capability
degradation) plus 5 in api for buildSteerWiring gating, and 2
Redis-gated cross-replica transport specs.

* 🔒 fix: Codex round 2 — evict tombstones, scope the empty-boundary disarm, honest resumes

All four server findings were fresh consequences of the round-1 fixes,
which is the review doing exactly what it should.

- Tombstone cap refused new entries instead of evicting. Every drained
  or cancelled steer is tombstoned, not just preempting ones, so a
  generation that processed 20 steers exhausted the set and the
  late-arm race resurfaced silently. Now evicts oldest-first (Set
  iteration is insertion-ordered), with the budget named
  PREEMPT_TOMBSTONE_MAX rather than an inline expression.

- The empty-boundary disarm I added in round 1 wiped the generation's
  ENTIRE armed set. A second steer can enqueue and arm between the
  atomic drain returning empty and the disarm running — that arm is
  backed by a live, uninjected queue item and must survive. The drain
  now snapshots the armed ids BEFORE draining
  (getArmedPreemptIds) and clearPreemptRequests takes an explicit id
  list instead of clearing everything.

- HITL resume finalized with a hardcoded unfinished: false. The
  boundary hook is re-registered on resume via buildSteerWiring, so a
  resumed segment can end on an empty preempt boundary exactly like a
  fresh one; finalizeResumedTurn now reads getPreemptStats() and the
  halt reason, matching the normal request path.

- Ownership moves on resume, so the job's recorded preemptCapable must
  describe the replica that will actually generate. Refreshed before
  resumeCompletion; a job created on a capable replica that resumes on
  an older one during a rolling deploy no longer acknowledges steers as
  interrupting.

Tests: +3 (scoped disarm sparing a post-snapshot arm, oldest-first
tombstone eviction, id-list disarm). 122 packages/api steering specs
green.

* 🚨 fix: Codex round 3 — deserialize preemptCapable from Redis (feature was dead under Redis)

The P1 here is the most consequential defect in the whole feature, and
it was introduced by round 1's own capability fix.

- `RedisJobStore.serializeJob` writes booleans generically, so
  `preemptCapable` reached Redis — but `deserializeJob` is an EXPLICIT
  field map and had no line for it. Every `getJob()` therefore dropped
  the flag, `job.metadata.preemptCapable` was always undefined, and
  `handleSteerRequest` computed `preemptArmed: false` unconditionally.
  Interrupt & steer would have silently degraded to ordinary
  tool-boundary steering in EVERY Redis deployment — i.e. the feature
  shipping as a no-op in production while passing every in-memory test.
  Now deserialized, with a round-trip assertion in the metadata spec
  that fails (`Received: undefined`) against the unfixed store.

- The resume capability refresh moved from just-before
  `resumeCompletion` to immediately after `approvals.resolve` claims
  the run. That call already flips the job back to `running`, so the
  steer route accepts requests from that instant; leaving the refresh
  135 lines later (across the whole client reconstruction) left a real
  window where a steer read the PREVIOUS owner's capability. Not the
  fully atomic transition Codex suggested — that reaches into the
  approvals Lua — but it shrinks the window from seconds to one await,
  which is proportionate for a label-accuracy issue.

Refuted: "avoid triggering preemption inside subagents". The premise —
that the run-wide poll can seal a subagent stream — does not hold
against the shipped SDK. Child graphs are constructed with
`subagentScope: true` (SubagentExecutor) and `preemption` is NOT
propagated into child inputs, while `canClaimPreemptSeal()` requires
`!subagentScope && preemption != null`. Both conditions fail
independently, so a subagent can never claim a seal and the boundary
cannot fire with `agentId` set. The `input.agentId != null` guard in
the hook is defensive depth, not the thing standing between us and the
described failure.

140 packages/api specs green.

* 🔁 fix: Codex round 4 — re-arm durable interrupt steers when resume moves owners

- An arm lives only in the owning replica's runtime plus a transient
  pub/sub message, while the steer's `preempt` flag is durable on the
  queue item. A HITL resume landing on a different replica therefore
  started with an empty armed set and a poll stuck false, so an
  interrupt the user had already been ACKed for silently waited for an
  ordinary tool boundary. New `GenerationJobManager.rearmQueuedPreempts`
  rebuilds the armed set by peeking the durable queue (fenced on the
  generation) and re-arming every item flagged `preempt`; resume calls
  it right after claiming. Safe by construction: every item peeked is
  still queued, so no drained steer can be resurrected.

- Capability-refresh failure now logs at error rather than warn, but
  deliberately does NOT fail the resume — see the reply on that thread.

Tests: +2 (rebuild from queue arms only the flagged item and reports
the count; a stale generation arms nothing). 124 packages/api steering
specs green.

* 📡 fix: Codex round 5 — acknowledge only what was actually armed

- A cross-replica arm was fire-and-forget: `emitPreempt` logged its own
  publish failure and `requestPreempt` returned void, so the route
  answered `preempt: true` even when the owner never armed a poll. The
  steer still injected at the next tool boundary, but the chip claimed
  an interrupt that could not happen — and unlike HITL resume, an
  ordinary running generation had no durable reconciliation to recover
  it.

  `emitPreempt` now resolves to the subscriber count and rejects on
  failure; `requestPreempt` is async and returns whether the arm truly
  landed (owned locally, or delivered to at least one subscriber). The
  202 reports THAT rather than what was asked for, so the chip relabels
  to ordinary steering exactly as it does for a capability-degraded
  deployment. Errors are swallowed into `false` — an unarmed interrupt
  is a downgrade, never a failed steer.

- The owner capability is re-read immediately before enqueue rather
  than reused from the top of the guard ladder. `checkAgentAccess` and
  file resolution are awaits, so a request can span an entire HITL
  pause/resume that moves ownership to a replica with different
  capability and rewrites that very flag. Only paid for by requests
  that actually asked to interrupt.

Tests: +3 (not-armed when the publish reaches nobody; armed when this
replica owns the generation; a throwing publish downgrades instead of
propagating). 127 packages/api steering specs green.

* 🎯 fix: Codex round 6 — real ownership, confirmed disarms, and a CI regression of my own

Three review findings plus three CI failures the round-5 commit caused.

Review:
- Ownership came from `runtimeState`, which a cross-replica `getJob`
  populates with a FACADE runtime on any replica that merely read the
  job. Matching `createdAt` therefore proved only "we looked at this
  job", so a non-owner could arm nothing and report success. Ownership
  now comes from `ownedJobs`, the actual owner map.
- `armPreemptIds` returns how many ids it accepted, and a local arm is
  only reported as armed when one was. A tombstoned id (its steer
  drained at an ordinary boundary mid-request) no longer answers
  `preempt: true` for an interrupt that cannot happen.
- The cancel disarm is awaited. A dropped clear is worse than a dropped
  arm: the owner keeps a level-triggered request for a steer that no
  longer exists, seals its next chunk and truncates an unrelated
  answer. The boundary drain's own call stays non-blocking — there the
  owner is local, so the disarm is already effective and awaiting the
  informational publish would only delay injection.
- Subscriber count is NOT read as proof of owner receipt: the count
  includes this replica's own facade subscription. A successful publish
  reports armed, a rejected one does not. Documented rather than
  papered over — see the acknowledgement-semantics note on the PR.

CI regressions from round 5, all mine:
- `registerPreemptSubscription` was AWAITED at both runtime-init sites,
  so job creation blocked on a second Redis channel subscription and
  hung when that subscribe was slow. Abort is awaited because a missed
  abort strands a run; a missed preempt only degrades that steer to the
  next tool boundary, so it now registers without gating createJob.
- Two api specs mocked `@librechat/api` without the newly imported
  `isSteerPreemptSupported`, so the call threw before createJob; and one
  exact-match assertion needed the new `preemptCapable` metadata field.
- My own Redis integration spec asserted arm-before-clear ordering,
  which two publishes carry no guarantee of — the receiving tombstone
  exists precisely because of that. Now asserts delivery and payload
  fidelity, order-independent.

158 packages/api specs, 27 api specs green.

* 🧭 fix: Codex round 7 — settle the acknowledgement semantics (Option A)

Round 7's second finding is the incoherence I flagged on the PR: the
route persisted `preempt: true` on the durable queue item while
returning `preempt: false` when delivery could not be confirmed. Those
two then disagreed, and `rearmQueuedPreempts` trusts the DURABLE one —
so a resumed owner would honour an interrupt the client had explicitly
been told degraded to ordinary steering.

Rather than patch the disagreement, this settles the meaning:

`preempt` in the 202 means "queued as an interrupt request", NOT "a
seal is guaranteed". It mirrors `SteerQueueItem.preempt` exactly, so
the response, the durable record, and the resume-time re-arm can never
disagree. The gates that ARE knowable stay — the owner's recorded
capability and a successful enqueue. Everything past that degrades to
the documented fallback of injecting at the next tool boundary.

A route cannot synchronously know whether another replica will seal:
proving it needs a correlated request/response over pub-sub, and even
that only proves the owner heard, not that it is still streaming when
the arm lands. Four rounds of tightening this boolean each surfaced a
narrower case; the sequence does not converge, so the invariant is now
"the flag describes the durable decision" and an unconfirmed arm logs a
warning instead of rewriting the answer.

Also from this round: a failed disarm publish is retried once and its
outcome reported. `handleSteerCancel` keeps `removed: true` — the steer
really did leave the queue, and saying otherwise would make the client
re-show a chip for a steer that can never arrive — and adds
`disarmed: false` so the residual risk is visible rather than swallowed.
Damage stays bounded regardless: the empty-boundary self-clear disarms
the generation after a single seal.

Tests: +1 pinning the response/durable-flag invariant. 159
packages/api specs green.

* 🧹 fix: Codex round 8 — remove the unverifiable disarm signal

Round 8 found the same over-promise on the disarm side that round 7
corrected on the arm side, so this applies the same answer rather than
patching around it.

The `disarmed: false` field added in round 7 was both unreliable and
unused: a resolved publish is not proof the owner heard it (the
delivery count includes this replica's own facade subscription), and it
was never threaded into `CancelSteerResponse` or read by any client. A
signal that claims a certainty the transport cannot provide is worse
than no signal — it invites callers to trust it.

Removed from the response. The retry stays, because it genuinely
reduces the failure rate, and `noteSteersRemoved` still returns whether
the publish succeeded FOR LOGGING, now documented explicitly as
"published without error", not "the owner disarmed".

Disarm is best effort with a bounded, self-healing failure: if the
clear is lost the owner seals once, the empty-boundary self-clear
disarms the generation, and the turn is persisted `unfinished: true`
rather than silently truncated. Tightening that further needs a
correlated request/response over pub-sub with a timeout — noted on the
PR as the deliberate boundary of this design rather than an oversight.

130 packages/api steering specs green.

* 🧽 fix: Codex round 9 — spend snapshot arms on nonempty drains too

The round-6 scoping fix only cleared the pre-drain snapshot when the
drain came back EMPTY. On a nonempty drain the `finally` cleared just
the drained ids, so a stale arm — typically a cancel whose
cross-replica clear was lost — survived the boundary. It would then
immediately seal the continuation meant to answer the steer that had
just been injected, and land on an empty boundary as
`preempt_incomplete`: the interrupt appears to work, and the answer to
it is truncated.

A boundary that runs has spent its seal, so everything armed at
snapshot time is spent whether or not it came back from the drain. The
`finally` now clears the union of the snapshot and the drained ids.
Arms that land AFTER the snapshot are still spared — their queue items
are live and uninjected, which is the property round 6 added.

Also fixes an api-workspace CI failure of mine: `resume.spec.js` stubs
`GenerationJobManager` wholesale, and the round-3/4 resume work added
two calls (`updateMetadata`, `rearmQueuedPreempts`) the stub did not
define, so 34 specs threw. Stub extended.

Tests: +2 (a nonempty drain clears a stale snapshot arm; a nonempty
drain spares an arm that landed mid-drain). Counterfactually verified —
the stale-arm spec fails against the unfixed drain. 132 packages/api
specs, 60 resume specs green.

* fix: never let a failed preempt subscription reject into the void

registerPreemptSubscription is called detached at both sites, so a
rejected Redis SUBSCRIBE became an unhandled rejection — process-fatal
under Node's default --unhandled-rejections=throw. The comment already
promised this path merely degrades steering; it now does.

Swallowed and logged inside the registration rather than at each call
site, so a future third caller cannot reintroduce the trap. Losing the
channel costs this generation's cross-replica preempts, not the server:
same-replica arming is runtime state and still works, and remote arms
fall back to the next tool boundary.

Verified counterfactually — the new spec surfaces SUBSCRIBE failed as an
unhandled rejection against the unfixed registration.

* docs: state the real blast radius of a failed preempt subscription

LibreChat's own entrypoints install a global unhandledRejection handler
that logs and keeps serving, so the escaping rejection this guards was
never fatal to this server — only to another consumer of @librechat/api
that installs no handler. The fix stands either way; the comment just
should not overstate what it prevents.

* test: cover the cross-replica preempt hop with two manager instances

Every other preempt test runs against a single manager, so the hop that
actually carries an interrupt in production had no coverage: the steer POST
lands on whichever replica the balancer picks, which is usually not the one
generating. Non-owner publishes, owner arms, owner's level-triggered poll
flips — none of that was exercised end to end.

Two GenerationJobManagerClass instances are a faithful replica pair here.
runtimeState and ownedJobs are private instance fields, there is no
module-level mutable state between them, and createStreamServices duplicates
a dedicated subscriber connection per call, so separate OS processes would
exercise the same objects over the same Redis.

Both assertions verified counterfactually against real Redis:
- Deleting the preemptCapable deserialization in RedisJobStore fails this
  with 'Expected: true, Received: undefined' — the exact P1 that shipped past
  every in-memory test and would have made the feature a silent no-op on
  every Redis deployment.
- Dropping the non-owner arm publish fails it with 'Received: false'.

* test: remove the fixed sleeps and vacuity from the cross-replica preempt test

Codex round 11, both findings, both on the test I added last commit.

P2 — the 300ms waits were load-bearing. Redis pub/sub never replays and the
owner's SUBSCRIBE is detached, so on a slow CI worker the publish could land
before anyone was listening and the test would fail against correct code.
Now it republishes until the owner's state converges, which is safe because
arms and clears are idempotent set writes keyed by steerId. Side effect: the
tests got ~10x faster (85ms/57ms vs 929ms/606ms) since they finish on
delivery rather than on a timer.

P3 — afterEach destroyed only the transports, leaving each manager alive in
its own cleanup-interval closure, still working against a dead transport.
Now tracks the managers and awaits destroy(), which disposes the job store
and its timer too. Matches how the rest of this file cleans up.

Fixing the sleeps exposed a third problem codex did not flag: the stale-arm
test could pass vacuously, because an undelivered arm and a fenced one look
identical. It now brackets the stale publish between two control arms — the
first proves the owner is listening before the stale one is sent, the second
proves it has had its chance to arrive.

Verified counterfactually against real Redis, and stable over 5 runs:
- dropping the preemptCapable deserialization fails with 'Received: undefined'
- dropping the non-owner arm publish times out both tests
- removing the generation fence fails the stale test with
  ["control-before", "steer-stale", "control-after"] — which also confirms
  the bracketing orders as intended rather than by luck

* fix: gate interrupt on the OWNER's capability alone, not the route's

Codex round 12. The comment above this gate already said 'the OWNER's
recorded capability, not this replica's probe' — and then the code ANDed in
isSteerPreemptSupported(), which is exactly this replica's probe. The
contradiction dates to the original commit; round 6 made the gate
owner-scoped and wrote that comment without removing the local conjunct.

The route never seals. It enqueues and publishes an arm, neither of which
touches the SDK, so during a rolling deploy a steer landing on an
un-upgraded replica silently lost its interrupt even though the owner could
seal. When the route IS the owner the probe is redundant anyway: the flag it
would consult is the one this process wrote at createJob.

The real degradation path is unchanged and still tested — an owner that
recorded no capability relabels to an ordinary steer. The test that pinned
the local probe asserted an impossible same-replica state (capable metadata
plus an incapable local SDK, when the metadata is written from that probe);
it now pins the mixed-SDK direction instead, and fails with
'Expected: true, Received: false' if the probe is put back.

* fix: reconcile arms at handover, and stop holding the 202 on a publish

Codex round 13, two of three findings.

P2 — rearmQueuedPreempts only ever ADDED. A replica that merely read the job
still installs a facade runtime and subscribes, so it can accept an arm and
then miss the best-effort clear that follows the drain. HITL resume promotes
that facade to owner, the union keeps the orphan, and the first resumed
stream seals on a steer no longer in the queue, drains nothing, and
truncates the resumed answer as preempt_incomplete. acquireResumedJobOwnership
only sets ownedJobs, so nothing else was clearing it. The durable queue is
the sole authority at a handover: arms it does not back are now disarmed and
tombstoned, so an in-flight publish cannot revive them either.

Worth recording that my own independent review raised this and my verifier
refuted it. Codex found it separately; two reviewers converging should have
outweighed one refutation.

P2 — the route awaited the arm publish before answering. The 202 reports
capability, not delivery, so the await could not change the response; it only
exposed the caller to Redis latency after the queue item was already durable.
A client that times out and retries mints a second steer while the first
stays queued, injecting the same instruction twice, whereas a lost publish
merely takes the tool-boundary fallback. Detached, with both outcomes logged.

All three tests verified counterfactually: union-only rearm fails the two new
handover specs, and re-awaiting the publish hangs the stalled-publish spec
until jest kills it.

* fix: snapshot arms before reading the queue at handover

Codex round 14 — a regression from my own round-13 fix, and a worse failure
than the one it corrected.

Round 13 read the durable queue first, then tombstoned any armed id the
snapshot did not back. But approvals.resolve reopens steering before
reconciliation runs, so another replica can commit a preempt steer and
publish its arm while the peek is in flight. That arm is then present locally
but absent from a snapshot taken before the steer existed, so a LIVE
interrupt the route already acknowledged got dropped — and tombstoned, which
blocks the re-arm, making it unrecoverable rather than merely late.

Fixed by inverting the two reads rather than by locking or paying a second
round trip. A steer is durably enqueued BEFORE its arm is published, so any
id in an arms-first snapshot was already queued when it was armed, and the
later peek must observe it unless it has since drained — which is exactly the
orphan this reconciliation exists to drop. Arms landing after the snapshot
are simply not candidates.

Also re-checks runtime identity across the await, since the generation can be
replaced while the queue read is in flight.

New spec injects a steer + arm during the peek and verifies it survives;
against the round-13 ordering it fails with Received array: [].

* fix: bound the cancel disarm wait and fence enqueue to its generation

Codex round 15.

P2 — the cancel awaited its disarm publish unbounded. ioredis queues
commands during an outage rather than rejecting, so that await could hang for
the length of the outage with the steer ALREADY durably cancelled; a client
that gives up then treats the cancel as failed and restores a chip for a
steer that can never produce an applied event. Every successful cancel
publishes, so ordinary steers were exposed too, not only preemptive ones.
Now bounded at 1s, with the publish continuing behind it — its retry and
logging are unchanged, it is just no longer in front of the response. This is
the sibling of round 13's arm-publish finding; I fixed one path and left this
one.

P3 — enqueue was not fenced to the generation the capability decision was
made against. The access checks, file resolution and owner re-read are all
awaits, so the run can be replaced before the enqueue: the item then lands on
the REPLACEMENT queue while the durable preempt flag and the arm still name
the previous epoch, the arm is fenced out at the owner, and the 202 promises
an interrupt that cannot happen. enqueueSteer now takes an expected
generation, mirroring drain/peek, and the Redis path enforces it inside
STEER_ENQUEUE_LUA so the check is atomic with the push rather than racing it.

All three new specs verified counterfactually, including the Lua guard
against real Redis (removing it returns 1 where -1 is required).

* fix: fence the steer to its authorized generation, bound resume setup, keep preempt when Redis parks

Codex round 16, all three findings.

P2 — round 15 fenced the enqueue to owner.createdAt, the RE-READ job. Every
guard above it (ownership, tenant, paused-state, agent ACL) ran against the
job read at the top, so if the run was replaced during those awaits the fence
happily accepted the steer into a generation the request was never authorized
against, carrying the wrong agent's metadata. Now rejects on any mismatch
between the validated job and the re-read.

P2 — resume awaited its steering bookkeeping unbounded, after
approvals.resolve had consumed the action and flipped the job to running, and
outside the resume lifecycle's own try/finally. .catch does not fire on a
promise that never settles, which is what ioredis produces during an outage,
so the client times out, its retry gets a 409 for a spent action, and no
cleanup runs. Bounded at 1s with the writes finishing in the background.

P3 — Redis parks leftover steers inside its terminal-transition Lua, which
projects item fields one by one, so preempt was silently dropped and a steer
recovered from /chat/status lost its interrupting label. Added to both
projections.

All three verified counterfactually, two against real Redis. Worth recording
that my first version of the generation-mismatch test was VACUOUS — it faked
a createdAt matching no live job, so the round-15 enqueue fence rejected it
for the wrong reason and the test passed with the guard removed. Rewritten to
replace the run for real; it now fails with 'Expected 404, Received 202'.

🎟️ fix: Claim Idempotency Keys to Dedup Retried Generation Requests and Prevent Double Billing (#14344)
* 🐛 fix: Dedup retried start-generation requests to prevent duplicate billing

A lost or reset start-generation response makes the client re-POST the
identical payload (up to 3x on network errors). The resumable-stream
controller had no idempotency: createJob unconditionally overwrote the
running job without aborting the prior one, so both requests ran full
LLM completions and both billed while the UI showed only one (#14339).

Add a stable per-submission clientRequestId (uuid, fresh per ask() so a
regenerate differs, reused across the start-generation retries) and an
atomic claim on the job store keyed by userId:clientRequestId. The first
request wins and generates; a retried POST loses the claim and receives
the original stream, which the client subscribes to and replays - no
second billed generation.

- IJobStore.claimIdempotencyKey/releaseIdempotencyKey (in-memory Map+TTL,
  Redis single-key SET NX PX + GET Lua, cluster-safe)
- GenerationJobManager.claimGeneration/releaseGeneration (20m TTL)
- Controller claims before the concurrency check, dedups with a resumed
  response, releases on start-failure/429
- clientRequestId threaded through TSubmission/TPayload/createPayload

* 🐛 fix: Harden start-generation dedup (Codex review)

Address three P2 findings on the idempotency path:

- Resume replay: a deduped retry now subscribes with resume=true so the
  client replays prior content and any pending-action from the running
  stream instead of only live events (cross-replica / HITL correctness).
  startGeneration returns { streamId, resumed } and the response's
  status:'resumed' drives the subscribe mode.
- Wait for the job record: a duplicate that loses the claim now waits
  briefly for the winner to create the job before returning the stream
  (a stream with no job 404s terminally). If the winner has not
  materialized, return 503 SERVER_NOT_READY so the client retries via the
  existing readiness path instead of attaching to a dead stream.
- Release only owned claims: track whether the request actually won the
  claim; the 429 and init-error paths no longer release a claim owned by
  another in-flight generation (fail-open path could erase it and
  re-enable double billing).

Adds controller tests covering dedup, the 503 race fallback, win-then-
create, and claim-release ownership on 429 / fail-open.

* 🐛 fix: Don't trap deduped retries on missing job records (Codex review)

The previous round returned 503 SERVER_NOT_READY when a deduped retry's
job record was absent. But a missing job usually means the original
generation already completed and was cleaned up (cleanupOnComplete) — the
correct recovery is to return the stream and let the client's subscribe
404 handler refetch the persisted messages. The 503 instead trapped the
send in a readiness-retry loop until the client's window expired.

Keep the bounded wait (it still covers the job-about-to-be-created race)
but always return the resumed stream afterward; a gone/never-created job
recovers via the client's existing 404 path instead of being treated as
indefinitely starting. Updated the controller test accordingly.

* 🐛 fix: Gate deduped resume on claim age, not just job presence (Codex review)

Removing the 503 entirely (previous round) reintroduced the inverse race:
if the winning request stalls between claimGeneration and createJob, a
losing duplicate saw no job, returned status:'resumed' anyway, and the
client subscribed to a stream that did not exist yet — the 404 handler
tore the turn down while the winner went on to generate and bill with no
UI attached.

Distinguish the two missing-job cases by claim age (claimedAt now travels
on the claim value):
- fresh claim, no job yet → winner is still starting → 503 SERVER_NOT_READY
  so the client retries via the readiness path (bounded, not indefinite).
- old claim, no job → the original already completed and was cleaned up
  (or the winner died) → attach; the client's 404 handler refetches.

Tests cover both age branches.

* 🐛 fix: Scope dedup fail-open + keep resumed convos on 404 (Codex review)

- Fail-open only on claim acquisition: a store error while checking an
  already-confirmed existing claim no longer falls through to createJob
  (which would start a second billed generation during a Redis hiccup).
  Once claim.existing is known, a job-lookup error returns 503 retry.
- Don't drop a resumed convo on 404: the optimistic-conversation cleanup
  in useResumableSSE now runs only for fresh (non-resume) subscribes. A
  deduped resume whose original completed and was cleaned up 404s, but its
  conversation is persisted and must stay in the sidebar.

Adds a controller test for the job-lookup-error path (503, no createJob).

* 🐛 fix: Reconcile resumed convos on 404 instead of guessing (Codex review)

Round-4's !isResume guard fixed the completed-and-cleaned case (don't drop
a persisted convo) but left the inverse: a new-conversation retry deduped
to a claim whose original worker died before persisting still resumes,
404s, and — with removal skipped — leaves a phantom /c/<streamId> sidebar
entry.

Stop guessing keep-vs-remove on a resume 404. Reconcile against the
server: invalidate the conversations list so a real (persisted) convo
stays and a phantom is dropped. Fresh (non-resume) optimistic streams
still prune immediately. Adds a client test for the resume path.

* 🐛 fix: Finalize failed job before releasing its claim (Codex review)

In the initialization-error catch, the idempotency claim was released
before completeJob(streamId). A racing retry could win the released key
and createJob() the same streamId while this catch was still running, and
completeJob() (not guarded by the original createdAt) would then abort the
replacement. Finalize the failed job first, then release the claim.

Adds a controller test asserting completeJob precedes releaseGeneration.

* 🐛 fix: Clear claims on destroy + survive completeJob failure (Codex review)

- InMemoryJobStore.destroy() now clears the idempotencyClaims map, so a
  reused/reconfigured store instance doesn't dedup a fresh start against a
  torn-down job's stale claim.
- Init-error cleanup: completeJob() is swallowed so a store-hiccup
  rejection can no longer skip the idempotency-key release and the
  pending-request decrement (which would wedge the retry behind the claim
  and leak the concurrency slot). A failed completeJob finalized nothing,
  so releasing afterward still can't abort a later replacement.

Tests: claims cleared on destroy; release + pending decrement still run
when completeJob rejects.

🧭 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.

* 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).

* 🖇️ feat: Reference Selected Chat Text with Multi-Quote Popup

Add a ChatGPT/Codex-style quote feature: selecting text in any message shows
an 'Add to chat' popup that accumulates removable quote chips above the
composer. On submit, the excerpts are merged into the user message text as
Markdown blockquotes (counted in the user message token count, not a system
message) and persisted on the message so they render on the user bubble and
survive reload.

- packages/api: add getReferencedQuotes + mergeQuotedText helpers (blockquote merge, length/count caps) with unit tests
- BaseClient.sendMessage: temporarily merge req.body.quotes into userMessage.text before buildMessages, restore clean text, persist quotes array
- data-schemas + data-provider: add optional quotes field to message schema/type
- client: pendingQuotesByConvoId atom, QuoteButton selection popup, PendingQuoteChips composer row, MessageQuotes persistent display
- useChatFunctions: drain pending quotes onto the message, carry forward on regenerate
- add localization keys and component/integration tests

* 🧪 test: Add Playwright e2e for chat quote feature

Add e2e/specs/mock/quotes.spec.ts covering select -> 'Add to chat' popup ->
chip -> send -> persistent reference block -> reload, plus multi-select
accumulation and chip removal. Selection is driven programmatically (real DOM
Range + dispatched mouseup) to summon the popup deterministically.

Add data-testid hooks (add-to-chat-button, pending-quote-chips, message-quotes)
to the quote components for stable selectors.

* 🛡️ fix: Address Codex review on quote feature

- Run PII filter + OpenAI moderation over req.body.quotes (P1): quoted excerpts
  are merged into the model-facing user message, so they must clear the same
  filters; a crafted quotes payload could otherwise bypass them. Adds tests.
- Carry quotes through edit/save-and-submit replays (overrideQuotes in
  EditMessage), mirroring overrideManualSkills, so edited turns keep context.
- Hide the quote UI for Assistants endpoints (which bypass BaseClient merge),
  so users can't queue quotes the assistant never receives.
- Clear pending quote/skill queues by resolved conversationId in useClearStates,
  not the UI index, so queued-but-unsent selections don't linger in Recoil.
- Cap queued quotes client-side at 10 to match the backend QUOTE_MAX_COUNT, so
  the composer never shows more quotes than are actually sent.

* 🧵 fix: Durably re-merge quotes + Codex round 2

Address Codex's re-review of the quote feature:

- Durable history re-merge (per maintainer decision): quotes are no longer
  merged at request time and stripped; instead each user message's persisted
  message.quotes is merged into its formatted content in AgentClient.buildMessages
  (new prependQuotes helper) for current AND historical turns. The model
  receives the referenced context on every prompt and the token count stays
  consistent with what was persisted; stored text stays clean for display.
- Attach normalized quotes to the user message in handleStartMethods (before
  getReqData/onStart) so the optimistic bubble, resumable abort metadata, and
  saved row all carry them (fixes the abort-metadata gap).
- Skip the quote drain entirely for Assistants endpoints in useChatFunctions,
  leaving the pending atom intact (UI is already hidden there).
- Normalize req.body.quotes via getReferencedQuotes before moderation/PII so
  only the trimmed/truncated/capped excerpts the model will receive are checked.
- Tests: prependQuotes unit tests; BaseClient quote tests assert early
  attachment + clean text; e2e now verifies the model receives the merged
  blockquote on the current turn and re-merged from history on a later turn
  (new E2E_ASSERT_QUOTE mock marker).

* 🔗 fix: Quote share/memo/abort/PII gaps (Codex round 3)

- Shared links: include quotes in the anonymized projection + SharedMessage
  type (+test) so the /share view renders the same reference blocks as the
  owner, mirroring manualSkills/alwaysAppliedSkills.
- MessageRender memo: compare quotes length so a server/resume copy whose only
  change is the quote list re-renders (the block no longer goes stale/missing).
- Resumable job metadata: include quotes in the userMessage written to
  GenerationJobManager so a reload/reconnect mid-stream reconstructs the chips.
- PII + moderation: also scan the merged blockquote+text exactly as the model
  receives it, so a secret split across a quote and the typed body (each clean
  alone) is caught (+cross-boundary test).
- e2e: make quote-add robust against the auto-scroll-dismisses-selection race
  via a retried select+click helper.

* 🛑 fix: Keep quotes on aborted turn's request message (Codex round 4)

abortMiddleware reconstructs finalEvent.requestMessage from jobData.userMessage
but only copied ids + text; include quotes so a stopped quoted turn keeps its
MessageQuotes in the UI and a regenerate-before-reload still sends the
referenced context. Completes the resumable-metadata fix from the prior round.

* 🧮 fix: Quote recount + preliminary abort metadata (Codex round 5)

- Force a canonical token recount for messages carrying quotes in
  AgentClient.buildMessages, so a plain text-only Save edit (which recomputes
  tokenCount from text alone) can't leave a stale, quote-excluding count that
  undercounts context on later turns — recount from the quote-merged copy
  self-heals it.
- Seed normalized quotes into the preliminary userMessage metadata
  (getPreliminaryUserMessage), so an abort during init/tool-loading (before
  onStart) still reconstructs the stopped turn's MessageQuotes.

*  fix: Add getReferencedQuotes to controller test mocks (CI)

request.js's getPreliminaryUserMessage now calls getReferencedQuotes; the
agents controller specs mock @librechat/api wholesale, so the mock must export
it or the call throws and cascades. Added a faithful mock (normalize/cap,
null when empty) to request.resumeMetadata.spec.js and jobReplacement.spec.js.

* 📐 fix: Quotes in context projection + resumable metadata (Codex round 6)

- Context-usage projection (resolveContextProjection): select message.quotes,
  prepend them into the projected user text, and recount quoted messages so the
  context gauge counts the same prompt the model receives (a text-only Save edit
  no longer makes the gauge undercount / over-report remaining budget).
- Resumable job metadata: trackUserMessage (created-event rewrite) and abortJob
  (final requestMessage) now carry quotes; SerializableJobData.userMessage and
  CreatedEvent.message gained an optional quotes field. With the cross-replica
  created-event spread, stopping/reconnecting a quoted turn after the created
  event keeps its MessageQuotes.

* 💬 feat: Collapse multi-select quotes into one chip with hover popup

Composer feedback: the quote chip area now shows a single chip — the excerpt
text for one selection, or a collapsed "{n} selections" pill for multiple,
with a hover popup (HoverCard) listing every excerpt and a per-item remove. The
chip is taller (py-1.5/text-sm) to read less skinny. Adds com_ui_quote_selections
and com_ui_remove_all_quotes; updates unit + e2e tests (e2e drives the count via
a data-quote-count hook and exercises the hover popup).

*  fix: Make multi-selection quote popup keyboard accessible

The collapsed "{n} selections" pill used a HoverCard, which Radix only opens on
pointer hover — its interactive content was unreachable by keyboard. Replaced it
with a Popover: the trigger is a real button that opens on click / Enter / Space
(focus moves into the list, each excerpt's × is tab-navigable, Escape closes and
restores focus), with hover-open preserved for mouse via controlled open state +
a close grace period. Hover-initiated opens skip auto-focus so they don't pull
focus off the composer. Adds an e2e asserting keyboard open/close.

* 📐 fix: Clamp the Add-to-chat button within the viewport (Codex round 7)

The floating selection button positioned via translate(-50%,-100%) (bottom-center
anchor) but clamped top/left as if they were its top-left, so a selection near
the viewport top or sides could render the button partly/fully offscreen. Now it
measures the button (ref + useLayoutEffect) and computes an on-screen top-left —
clamping by the full width within side margins and flipping below the selection
when there's no room above — with no transform, and stays hidden until measured
so it never flashes at an unclamped spot.

* ↩️ fix: Restore pending quotes on early-abort draft (Codex round 8)

When a turn is stopped before the created event (e.g. during tool/MCP init), the
final handler restores requestMessage.text to the draft, but the pending-quote
atom was already drained on submit — so a retry sent no quotes. The abort
requestMessage now carries quotes (preliminary metadata + abort fixes), so the
three early-abort/no-response draft-restore paths in useEventHandlers now also
re-queue pendingQuotesByConvoId from requestMessage.quotes.

*  fix: Use Ariakit Popover for quote selections (keyboard focus)

The multi-selection popup used a hand-rolled Radix Popover with Popover.Anchor +
a manual button, so Radix had no trigger to return focus to — Escape dumped
focus to the page top. Refactored to Ariakit (the codebase's popover primitive,
per DropdownPopup/Fork): the `PopoverDisclosure` is the real trigger, so Escape
closes and returns focus to the composer instead of the top of the page. Keyboard
opens (Enter/Space) autofocus into the list and tab through each excerpt's remove;
hover opens for mouse with autofocus suppressed so it never pulls focus off the
composer. e2e asserts the keyboard open/navigate/Escape flow keeps focus on a
real control (never BODY).

🏷️ fix: Preserve Generated Conversation Title on Stop (#13568)
Immediate title generation discarded an already-generated title when the
user stopped the turn, both in the backend (skipped saveConvo) and the
frontend (rolled back the streamed title), leaving the chat as "Untitled"
in the interim and "New Chat" after refresh.

Split the title abort into two signals: `signal` still cancels an in-flight
title model call on Stop, while a new `discardSignal` discards an
already-generated title only when the stream is superseded by a newer run
or the turn fails. A plain user Stop now persists and keeps the title.
The frontend no longer rolls back a real, already-applied title on an
aborted final event.

*  feat: Immediate Conversation Title Generation

Generate conversation titles as soon as the request is made (in parallel
with the response, from the user's first message) as the new default,
fixing the #13318 race where a transient /gen_title 404 left new chats
stuck on "New Chat".

- Add per-endpoint `titleTiming` ('immediate' | 'final') to baseEndpointSchema;
  `endpoints.all` acts as the global default, unset = immediate. Resolve via
  a new `resolveTitleTiming` helper (`all` takes precedence).
- Fire title generation in parallel with `sendMessage`; `titleConvo` waits
  (bounded, abortable) for the agent run and titles from the user input only.
  Persist after the conversation row exists; defer `disposeClient` until the
  title settles.
- Expose `titleGenerationTiming` via startup config; `useTitleGeneration`
  fetches eagerly in immediate mode with a bounded 404 retry and never treats
  a transient 404 as final. Skip title queueing for temporary conversations.
- Supersedes #13329 while incorporating its bounded 404-retry.

* 🩹 fix: Address Copilot review findings on title timing

- Guard against an undefined conversationId in addTitle (skip + warn) so the
  gen_title cache key can't collide as `userId-undefined` and saveConvo is
  never called without a conversationId.
- Gate the title `useQueries` on `enabled` so no /gen_title request fires while
  unauthenticated (e.g. after logout) even if the module queue holds IDs.
- Drop the stale `conversationId` param from the titleConvo JSDoc.
- Add a regression test for the undefined-conversationId guard.

* 🧵 fix: Harden immediate-title edge cases from codex review

- Cancel in-flight immediate title generation when the request aborts: thread
  job.abortController.signal through addTitle so pressing Stop on a new chat
  neither consumes the title model nor surfaces a title for a cancelled turn.
- Preserve a locally-applied title when the final SSE event's conversation
  carries no title yet (built before the title was saved), so long immediate-mode
  responses no longer revert the chat to "New Chat" until reload.
- Guarantee one full post-completion gen_title fetch cycle before giving up, so a
  `final`-mode title (generated only after the stream ends) is still fetched under
  a global `immediate` default instead of being stranded.
- Add regression tests for the abort propagation and the undefined-conversationId guard.

* 🔁 fix: Correct title abort, post-completion refetch, and replacement ordering

Follow-up to codex review of the immediate-title fixes:

- Use a dedicated title AbortController instead of `job.abortController`. The
  latter is also aborted by `completeJob` on *successful* completion, which
  cancelled any title slower than a short response. The title is now cancelled
  only on a real user Stop or when the stream is replaced; a completed-then-
  aborted title is discarded (no save, cache cleared) rather than persisted.
- Reset (not remove) the post-completion title query: `resetQueries` refetches
  the mounted observer with a fresh retry budget, whereas `removeQueries` left it
  stuck in its error state, so the promised post-completion cycle never ran.
- Run the job-replacement check before resolving `convoReady`, and on a replaced
  stream cancel/discard the stale title so a discarded prompt can't persist a title.

* 🧷 fix: Tighten title abort ordering and endpoint-level timing resolution

Follow-up to codex review:

- Abort the title controller before resolving `convoReady` on a stopped turn, so
  the title task can't resume and persist before the later abort.
- Cancel the title and unblock its waits on ANY send failure (not just user
  aborts): a preflight/quota failure before the run exists otherwise hangs
  `_waitForRun`, deferring client disposal until the 45s title timeout.
- Resolve `titleTiming` for custom endpoints via `getCustomEndpointConfig`
  (their config lives under `endpoints.custom[]`, not `endpoints[endpoint]`).
- Derive the startup `titleGenerationTiming` via `resolveTitleTiming` for the
  agents endpoint so an endpoint-level `final` (without `endpoints.all`) is honored
  client-side instead of defaulting to immediate and burning eager gen_title polls.

* 🪢 fix: Per-agent title timing and safer abort/replacement handling

Follow-up to codex review:

- Resolve `titleTiming` from the agent's actual endpoint after initialization, so a
  per-endpoint `final` override on a custom/provider endpoint backing an (ephemeral)
  agent is honored instead of always using the `agents` endpoint's value.
- Don't preserve a locally-fetched title on a stopped (unfinished) turn: the server
  cancels and discards that title, so keeping it client-side would diverge from
  server state and leave the stopped chat titled until reload.
- On abort/replacement, only delete the cached title if it still holds THIS task's
  value — a replacement stream shares the `userId-conversationId` key and may have
  already cached its own valid title that must not be removed.

* 🪞 fix: Mirror AgentClient title-config resolution for titleTiming

Per maintainer guidance, keep titleTiming resolution identical to how
`AgentClient#titleConvo` already resolves the endpoint config — `endpoints.all`
is the intended global override and the agent's actual provider endpoint is used:

- Resolve via `endpoints.all ?? endpoints[endpoint] ?? getProviderConfig(endpoint)
  .customEndpointConfig` (was using `getCustomEndpointConfig` directly). Going
  through `getProviderConfig` picks up its case-insensitive fallback for normalized
  provider names (e.g. `openrouter` → `OpenRouter`), so a custom endpoint's
  `titleTiming` is honored like its other title settings.
- Add `titleTiming` to the Azure endpoint schema `.pick()` so
  `endpoints.azureOpenAI.titleTiming` is no longer silently stripped by Zod.

Note: per-endpoint title settings being skipped when `endpoints.all` is present is
the existing, intended global-override behavior — not changed here.

* 🧪 test: Cover useTitleGeneration effect logic (integration)

Adds a deterministic white-box integration test that drives the real hook's
React effects with a controllable react-query surface, locking down the
stateful decisions that previously had no coverage:

- immediate mode fetches a queued conversation while its stream is still active
- final mode gates until the stream completes, then becomes eligible
- success applies the fetched title to the conversation caches
- a 404 while active defers (removeQueries) instead of giving up
- a 404 after completion forces a fresh fetch via resetQueries (post-completion remount)

🏞️ fix: Image Preview Refactor with Accessibility Enhancements (#11217)
* 🔧 fix: Prevent race condition by saving user messages before final event in ResumableAgentController

- Updated the ResumableAgentController to save user messages prior to sending the final event. This change addresses a potential race condition where the client might refetch data before the database is updated.
- Removed redundant message saving logic that was previously located after the final event handling, ensuring a more reliable message processing flow.

* style: improve image preview dialogs with ChatGPT-like UX and accessibility

Refactored image preview dialogs (DialogImage and ImagePreview) to provide
a cleaner, more intuitive user experience similar to ChatGPT's implementation.

## DialogImage.tsx (generated images)
- Replaced OGDialog/OGDialogContent with direct Radix Dialog primitives
  for finer control over behavior
- Full-screen dark overlay (bg-black/90) that closes on click outside image
- Restructured component so all interactive elements (close, download,
  details panel buttons) are inside DialogPrimitive.Content for proper
  focus trap and keyboard navigation
- Added onOpenAutoFocus to focus close button when dialog opens
- Added onCloseAutoFocus to return focus to trigger element on close
- Added triggerRef prop to enable focus restoration
- Removed animate-in/animate-out classes that caused stuttering on open
- Changed transition-all to transition-[margin] to prevent animation jank
- Added proper TypeScript types for component props

## ImagePreview.tsx (uploaded file thumbnails)
- Same Radix Dialog primitive refactor for consistent behavior
- Click-outside-to-close functionality
- Proper focus management with closeButtonRef and triggerRef
- Made button the container element to prevent focus ring clipping
- Added focus-visible ring styling for keyboard navigation visibility

## Image.tsx (image display component)
- Restructured so button is the outer container instead of being nested
  inside a div with overflow-hidden (which was clipping focus ring)
- Added visible focus-visible:ring styling with ring-offset
- Added aria-haspopup="dialog" for screen reader context
- Added triggerRef and passed to DialogImage for focus restoration

## Accessibility improvements
- Keyboard navigation now works properly (Tab cycles through buttons)
- Escape key closes dialog (or resets zoom if zoomed in)
- Focus is trapped within dialog when open
- Focus returns to trigger element when dialog closes
- Visible focus indicators on image buttons when focused via keyboard
- Proper ARIA attributes (aria-label, aria-haspopup, aria-hidden)

## UX improvements
- Click anywhere outside the image to close (not just specific regions)
- No more weird scroll/navigation issues
- Instant dialog open without stuttering animations
- Clean, minimal overlay without container/header chrome

* refactor: Improve click handling in image preview dialogs

Updated the click handling logic in ImagePreview and DialogImage components to ensure that the dialog only closes when clicking directly on the overlay or content background, enhancing user experience by preventing unintended closures when interacting with child elements. Additionally, clarified comments to reflect the new behavior.
