perf: Append Saved Message Ids Instead of Rebuilding the Conversation Array (#15141)
*  perf: Append Saved Message Ids Instead of Rebuilding the Conversation Array

Every saveConvo read every message id in the conversation (sorted) and
wrote the array back onto the document — twice per chat turn, O(n) in
conversation length, from a write path. The turn's savers know exactly
which message they just wrote, so they now pass it as
metadata.appendMessageIds and saveConvo $addToSet-s it, skipping the
read and the full-array rewrite. Every save without the option — titles,
archive, fork, import, threads — still rebuilds from the database, which
remains the heal point for the drift that message deletion has always
left behind (deletes never ran saveConvo).

The array's consumers read presence or length, or use it as an
optimistic cache placeholder, so incremental maintenance is
behaviorally identical; on traced turns the array stays exactly equal
to the messages collection.

Per-turn queries: 15 -> 13 (two Message.find gone), and the growing
array payload no longer crosses the wire twice per turn.

* 🎯 fix: Brand the Lineage-Only Resolved Conversation Instead of Guessing by Shape

The resolved-conversation files fast path treated an absent files
property as unresolved so the lineage-only partial from a bound
agent-event continuation could not silently hide a conversation's
uploads. But MongoDB never stores an empty files array, so nearly every
real conversation also lacks the property and the fast path never fired
— a follow-up turn on an upload-free conversation still paid the
getConvoFiles round trip.

The synthesized partial is the one object that cannot speak for the
database, so it now carries an explicit symbol brand
(PARTIAL_RESOLVED_CONVERSATION, non-serializing and invisible to key
iteration), and a stored document without files means what it means:
no files. Traced follow-up turns drop from 14 queries to 13.

* 🧪 test: Expect the Appended Message Id in the Route's saveConvo Metadata

messages-get.spec.js pins the exact metadata POST /api/messages passes to
saveConvo; the route now forwards the saved message's _id as
appendMessageIds, which is the behavior the append path depends on.

📄 fix: Serve Stored Text for "Upload as Text" File Downloads (#14723)
* 📄 fix: Serve Stored Text for Text-Source File Downloads

"Upload as Text" attachments store extracted content in the DB with
source 'text'; OCR uploads persist the OCR strategy name (e.g.
'mistral_ocr') as a filepath placeholder since no backing file exists.
The download route resolved these records to the local strategy and
passed the placeholder to fs.createReadStream, which failed with
ENOENT — and the response was never ended after the stream error, so
the request hung until the client timed out.

Serve the stored text directly as a .txt download for text-source
files (re-fetched by _id, as getFiles excludes 'text' by default),
and end the response on stream errors: 500 without the download
headers before headers are sent, otherwise abort the truncated
response so clients detect the failure.

🙈 feat: Config Option to Hide Response Feedback Buttons (#15085)
* feat: add interface option to hide response feedback buttons

Adds `interface.feedback` to librechat.yaml. When set to false, the
thumbs up/thumbs down buttons are removed from the message action row
and the feedback endpoint rejects writes with 403, so deployments that
do not consume the data can stop collecting it. Defaults to true.

* refactor: hoist the feedback gate out of the message row and into typed middleware

Reading startup config inside HoverButtons put a query observer and two Recoil
subscriptions on every message row, and rows never unmount, so the cost grew
with the conversation. Resolve the flag once per chat in useChatHelpers and
carry it on TMessageChatContext; useMessageActions withholds handleFeedback
when it is off, which the action row already treats as "no feedback controls".
The flag now stays false until the config resolves, so a disabled deployment
never flashes controls whose writes are rejected.

Move the server-side policy into requireFeedbackEnabled under packages/api so
the route keeps no policy of its own.

* test: stub the feedback gate in specs that replace the api package

The messages router now imports requireFeedbackEnabled, and express rejects an
undefined handler at require time, so every spec that mocks @librechat/api
wholesale has to carry the export.

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

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

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

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

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

Two blockers from the third external review round.

Terminal persistence visible to account deletion:

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

Stale-pause recovery retains scheduled evidence:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Alongside that:

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

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

* test: cover scheduled and subagent deletion drains

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

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

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

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

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

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

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

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

Both regressions fail without the normalizer.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Translate durable delivery state into the schedule outcome:

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

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

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

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

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

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

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

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

Addresses three findings from the fresh Codex review.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

🛰️ feat: Route Live Subagent Controls Across Replicas (#14971)
* feat: route live subagent controls across replicas

* fix: initialize task routing in cluster workers

* fix: harden cross-replica task routing

* fix: expire routed task owners independently

* fix: close cross-replica routing edge cases

* fix: bound owner refresh and close routed cancellation gaps

Refresh owned task registrations in bounded parallel batches so a full
heartbeat pass stays well inside the 30-second directory lease instead of
serializing one Redis EVAL per registration.

Route conversation-deletion cancellation through a dedicated owner-side
scope operation. The owner applies the deletion predicate to its complete
local task set, so a scope holding more children than the model-facing
list cap no longer leaves live executors running after their parent is
removed.

Key a consumed claim's retained response by its operation rather than by
one caller's correlation id, so a later poll recovers a terminal result
whose responses were all lost. Live claim statuses stay uncached so a
poll always observes the task's current state.

Type the model-facing `maxLength` bounds with a narrow local string
schema; the SDK's JsonSchemaType does not declare the keyword, and the
runtime checks continue to enforce the same limits.

* fix: retain claimed results apart from control replays

A consumed claim is the only routed response whose loss destroys data, so
it no longer shares one bounded cache with control replays that unrelated
command traffic can evict. Claims are retained under their own budget, and
the requester acknowledges a result it received so the owner releases the
copy immediately instead of holding it for the full replay window.

Resolve the post-delete cancellation pass from durable leases. The deleted
conversations cannot be read back, so re-reading each one only scaled the
cascade while probing the owner directory once per removed id; one lease
read now resolves every live child address instead.

* fix: never consume a result the owner cannot replay

Retention for consumed claims is bounded, so a burst of undelivered results
could evict an earlier one and lose it for good. The owner now admits a claim
only while it can retain a worst-case result, and refuses the routed claim
otherwise instead of consuming it, leaving the result on the task for a later
poll. Retained claims are never displaced; control replays keep evicting.

Key a control replay by the command itself rather than by one caller's
correlation id. The transport's own retry reuses a single envelope, but a
caller that saw the owner as unavailable reissues the command under a new id,
which steered, queued, or interrupted the child a second time.

* fix: own a claimed result until it is acknowledged

A consumed terminal result is task-owned state, not a cache entry. It now
carries no expiry at all: the owner holds it until a caller acknowledges
receipt, and only then is it released. Retention stays bounded by the
existing admission gate, which refuses a claim the owner could not keep
rather than consuming a result it might drop.

Identify a control by the caller's invocation instead of by its content.
The tool mints one id per invocation and routing carries it, so a routed
retransmission of that invocation replays the owner's result while two
deliberate identical commands arrive under distinct ids and both apply.
Content-derived identity could not tell those apart and would have
answered the second from a stale snapshot.

Wait for the dpkg frontend lock in the best-effort Playwright font step.
Its timeout kills npx while the apt-get it spawned keeps the lock, which
then failed the fatal Redis install and ended the MCP replica jobs before
any test ran (#14983).

* fix: treat acknowledgement as part of delivering a result

Publishing an acknowledgement once and ignoring the outcome meant a result
could be reported as delivered while the owner never learned it could let
go, and since that retention neither expires nor evicts, enough lost
acknowledgements would fill it and refuse every later remote claim.

An acknowledgement is now confirmed: publishing to zero subscribers is not
success, it retries inside the ordinary request window, and a claim whose
acknowledgement cannot be confirmed reports the retryable unavailable path
instead of handing back a result the owner still holds. A later poll
recovers that result and acknowledges it, and releasing is idempotent.
Owner registration also outlives the task while a result is unacknowledged,
so the retained result cannot become unreachable.

Take the control invocation identity from the provider's tool-call id
rather than minting one per execution, so replaying the same tool call
stays idempotent while two distinct calls with identical payloads both
apply.

* fix: own control invocations and cancellation plans at the task seam

Applies one logical control exactly once for its owning task rather than
in the transport, so a local caller and a routed caller of the same
invocation agree, and reusing an invocation id for different content is
refused instead of silently applied. Invocation identity now comes from
the run, agent, and provider tool-call id hashed to a bounded 32
characters, so a repeated `call_0` never bleeds across tasks and no id can
overrun the routed bound.

Cancellation for conversation deletion is now resolved into a plan while
those rows are still readable, then replayed against the owner directory
after the cascade is deleted. Owner registration is awaited before any
provider work, so a child that cannot be addressed never starts.

* fix: close subagent deletion, claim, and control invocation gaps

Bulk conversation deletion now runs behind a durable owner admission fence.
Draining alone could not close the race: a child admitted on another replica
after the drain read its leases would start provider work against a parent
about to disappear. The fence is written before any lease is read and each
child revalidates it after its own lease is written, so one of the two always
observes the other. It expires on its own, so a process lost mid-deletion
cannot leave an account unable to run subagents.

A terminal child result is no longer kept alive in the owning replica's
memory until someone acknowledges it. Collection is recorded durably on the
child's own message against the polling invocation, so the poll whose
response was lost recovers its own result while a different invocation is
told the result was already collected. Owner-side retention returns to an
ordinary bounded cache that expires, which is what abandoned polls needed:
they can no longer occupy claim capacity until the process restarts.

The deletion drain now cancels each task under one invocation held for the
whole drain, stops re-sending once the owner answers, and retries only
deliveries it could not confirm. A routed control replay also validates the
command fingerprint, so one invocation id carrying different content reaches
the owner to be refused instead of collecting the earlier command's success.

* test: assert the drain's calls before restoring its spies

Restoring a spy also clears its recorded calls, so the drain assertions
ran against an emptied mock. Formats the durable claim method tests.

* fix: close the follow-on gaps in the deletion fence and result claim

The admission fence now carries an ownership token, so an overlapping
deletion's fence is never lifted by the one that finishes first, and both
fence writes invalidate the cached auth user document. It also covers the
other bulk-delete path: `DELETE /` with no conversation filter removes every
conversation, so it runs behind the same fence rather than a bare drain.

The durable record now decides who holds a one-shot result. An owner replaying
a retained response could hand the same terminal claim to a second invocation;
that invocation is told the result was already collected, while the one that
consumed it still recovers its own. A task with no durable record to arbitrate
keeps whatever the owner answered.

Drain cancellation treats `not_found` as unconfirmed: a missing registration
while the durable lease is still live means the child may be running, so the
command is retried under its invocation once the owner republishes itself.
Control fingerprints are hashed, so retaining one per invocation costs a fixed
few bytes instead of a bounded message.

Claude-Session: https://claude.ai/code/session_01H1cCMDrTWaRNkmtKjpWELZ

* fix: hold every deletion fence and keep live idempotency records

An owner now holds one admission fence per concurrent bulk deletion instead
of one at a time, so admission reopens only when the last deletion finishes
regardless of completion order. Expired fences are pruned as new ones arrive
and the set is bounded, so an abandoned fence cannot accumulate or lock an
account out.

A failed durable claim write is no longer read as an absent record. Handing a
terminal result over without recording its claimant would let another
invocation collect the same one-shot output once the database recovered, so
the collection reports the retryable unavailable path and leaves the result
for a later poll.

Control invocation records now evict tasks the store no longer holds before
live ones, over a bounded scan. Dropping a live task's record would let a
caller retry apply its queue, steer, or interrupt a second time once the
transport replay had also expired.

Claude-Session: https://claude.ai/code/session_01H1cCMDrTWaRNkmtKjpWELZ

* fix: keep the deletion fence portable and never drop a live record

The admission fence is written with plain update operators again. DocumentDB
rejects pipeline-form updates, and this runs before any deletion, so the
pipeline form would have failed both bulk-delete endpoints outright on a
supported database target.

An excess deletion is now refused rather than silently displacing the oldest
active fence, which would have reopened admission for a deletion still
running. Expired fences are pruned before the cap is tested, so only genuinely
concurrent deletions count against it.

Control invocation records now sweep every settled task's entry when the
window fills, and a window of entirely live records refuses the new control
before touching the child instead of evicting one. Applying a command with no
room to record it would let the caller's own retry apply it twice.

Claude-Session: https://claude.ai/code/session_01H1cCMDrTWaRNkmtKjpWELZ

* fix: hold the fence, bound recovered results, and expire stale commands

The admission fence is renewed for as long as its deletion runs, so a very
large account or a stalled database cannot let it lapse while conversations
are still being removed. Only the deletion's own fence is renewed, and the
renewal stops with the operation.

Cancellation now covers every conversation the cascade removed, not only the
ones a plan named: a grandchild lives in its own parent's scope, which a plan
naming the deleted root never reaches.

A routed request carries the deadline its caller waits for, and an owner drops
one that arrives past it. A publisher disconnected mid-request queues the
envelope offline and delivers it after the caller was told the owner was
unavailable, which would otherwise steer a child the caller believes untouched.

A result recovered from its durable child message is bounded like a routed one.
The message keeps the child's untruncated output, so recovery could otherwise
return far more than the routed result limit allows.

* test: size the fence window so a renewal can be observed

The renewal test set a 30ms drain timeout but the five-minute grace window
dominates it, so the interval was 100 seconds and no renewal could fire
inside the test's deletion. The grace window is an option now, matching the
store's other timings, and the test sizes the window to 90ms.

* fix: wire the durable claim method and close the fence follow-ons

The production store never received `claimSubagentTaskResult`, so every
terminal result would have surfaced as unavailable once a task settled. The
host wires that object from JavaScript, where the factory's parameter type
checks nothing, so the factory now refuses a store missing any method it
calls rather than failing at the first claim.

The routing transport takes a dedicated publisher with the offline queue
disabled. The shared client held commands issued during a disconnect and
delivered them after the caller had given up, which the request deadline
narrowed but could not close inside the clock-skew allowance.

Fence renewal invalidates the cached auth document like the fence and release
paths, and a renewal reporting its entry gone re-takes the fence instead of
letting the deletion run on unfenced. The post-delete cancellation retries a
transiently unreachable owner: the conversations are already gone, so it is
the only pass that can still stop a late-admitted child.

A replaced replay entry no longer leaves its bytes counted, which would have
inflated the cache's total until unrelated responses were evicted.

* test: wait on observed lease renewal instead of a fixed delay

The shared-lease renewal test held a 60ms lease and slept 100ms before
asserting an overlapping worker was refused, so a loaded runner that
starved the 10ms heartbeat past the TTL let the lease lapse and the
second worker run. Spy on acquisition and renewal, then wait until a
renewal succeeds past the acquired lease's own deadline — direct
evidence the heartbeat carried it past expiry, with no timing
assumption — and give the lease enough headroom that a stalled timer
no longer decides the outcome.

* fix(agents): close the routing, fence, and cache gaps found in review

Five separate seams, each with its own failure:

`Cluster.duplicate` reads its first argument as a startup-node list and
its second as the overrides, unlike `Redis.duplicate`, so the publisher's
`enableOfflineQueue: false` was silently dropped under
`USE_REDIS_CLUSTER` and a command issued mid-disconnect could still
reach a child after its caller was told `unavailable`. Route both
through `duplicateIoRedisClient`.

The control window's capacity refusal ran before the store knew whether
it owned the task, so unrelated local load could veto a cancellation
bound for another replica. Establish that the task is local first and
leave a remote one to its owner's window.

`clearInterval` stops only future fence renewals. One already waiting on
the database could resolve after the release, read its own lifted fence
as expiry, and write a replacement that nothing remained to lift —
closing subagent admission for the account until it aged out. Track the
in-flight renewal, refuse overlapping passes, and await it before
releasing.

Every owner bounds its own task list, but the aggregation appended each
batch whole, so the model-facing list grew with the number of replicas
holding the scope. Cap the merged list while still reading every reply
for the stale-registration sweep.

The admission-fence prune commits independently of the fence that
follows it, so a refused or failed push left the cached auth document
describing entries the collection no longer held. Invalidate whichever
way the second write goes.

* fix(agents): cap the merged task list the poll tool actually reads

Each owner bounds its own reply and the remote aggregation bounds their
sum, but `listTasks` merged that bounded remote list with however many
children this replica owns and returned it whole. `check_background_task`
could therefore still receive roughly twice the advertised cap. Bound the
deduplicated, sorted result and export the cap so both seams share one
number.

* test: admit every task the merged-list cap test starts

The base store admits ten concurrent runs per scope by default, so
starting 150 at once left most refused for capacity and the assertion
never reached the merge it was written to check. Raise the cap for this
store only; admission is a different invariant with its own tests.

* fix(agents): let a deletion notice its admission fence lapsing

Renewal failures were logged and swallowed, so a run of rejected writes
let the last confirmed `fencedUntil` pass while the deletion carried on
believing admission was still closed — long enough for another replica
to admit a child against conversations about to be removed. Track the
deadline only a confirmed write advances, and check it after the drain,
before anything is deleted: nothing has been removed at that point, so
the operation fails closed and the caller retries once the fence can be
held. A lapse detected after the rows are gone is logged instead, since
reporting failure there would invite a retry against conversations that
no longer exist.

* test: raise both concurrency caps the merged-list test trips

Raising the per-scope limit left the store-wide `maxRunningTotal` at its
default hundred, so fifty of the hundred and fifty starts were still
refused. Verified against the base store directly this time: with only
the per-scope cap raised it admits a hundred, and with both raised it
admits all hundred and fifty.

* fix(agents): close the fence renewal gap and keep running tasks listed

A renewal that started before its deadline but landed after it was still
credited with extending the fence from its own start time, so a window in
which admission stood open was papered over: a child could take a lease
the drain had already read past and the deletion would proceed without
cancelling it. The deadline now only advances when the write lands while
the previous one still holds; anything later records a lapse the fence
cannot be restored backwards over.

The model-facing cap sorted oldest-first and sliced, which dropped the
newest tasks — including children that had only just started running,
and which the poll tool offers no other way to discover. Bound by status
instead: running children first, then the most recent settled results.
Both caps share one helper, and the routed aggregation now bounds after
its loop so the choice is made across every owner's reply rather than by
whichever answered first.

Claude-Session: https://claude.ai/code/session_01H1cCMDrTWaRNkmtKjpWELZ

* fix(agents): finish the cap and the fence at the seams they still missed

The status-aware cap only reached the requester: an owner's own reply
still sliced positionally, so a replica holding more than the cap dropped
its running children before the requester could bound anything. Both
sides now share `boundedTaskList`.

A fence that lapsed during the deletion itself was only logged. The rows
are gone by then, so failing is still wrong, but the child another
replica admitted while the fence was down is not: the fence is retaken
and the drain repeated to cancel it.

A child's lease renewal had the same retroactive hole the admission fence
had — Mongo filters on the `now` captured before the call, so a write
landing after the lease expired still moves the row forward, while an
owner drain reading active leases in that gap saw the thread as free. The
lease now carries its own deadline and a late renewal stops the executor.

* test: cover the lease lapse and the post-deletion re-drain

The owner-side cap shipped with a regression test; these two did not.
One drives a lease renewal that succeeds only after the lease it was
extending had expired and asserts the executor stops; the other lets the
fence lapse during the deletion itself and asserts a second drain runs
while the request still reports success.

🗄️ feat: Archive All Chats From Data Controls (#14885)
* feat: archive all chats from data controls

Adds an "Archive all chats" row under Data controls > Your data, next to
Shared links, with a confirmation dialog. It calls a new
POST /api/convos/archive/all endpoint backed by archiveAllConvos, which
archives every conversation currently visible to the user in a single
updateMany and refreshes the stats of every chat project the archived
conversations belonged to.

Temporary and retention-expired conversations are skipped: they are
already hidden from the chat list, so archiving them would only surface
them in the archived view. The update runs with timestamps disabled so
each conversation keeps its own updatedAt and the archived list stays
sorted by real activity.

Archiving a conversation now also drops the new-chat message cache alias
for it. A chat's first turn writes the same message array under both the
conversation key and the new-chat key, so without this the messages of a
just-archived chat kept rendering on the new chat screen until a reload.
Deleting already handled this; archiving did not.

* fix: keep archive-all state consistent

* fix: drop stale detail caches after bulk archive

* fix: harden archive-all request handling

* fix: reconcile archive batch failures

* Fix project stats refresh races and archive route boundary

* Fix archive-all review findings

* Fix archive scan index and partial-batch stats refresh

Reconcile project stats for already-committed archive batches when a later
batch fails, and index the archive scan as { user, _id } so non-tenant
pagination can use _id order.

* Fix Recoil reset after a partial archive-all failure

Refetch the submitted conversation on error and start a new chat only
when that conversation is still active and already archived.

* Fix archive recovery from resetting a newly opened chat

Re-read the active Recoil conversation after the archive-state lookup
resolves, so a slow getConversationById cannot start a new chat if the
user already opened another conversation.

* Fix project-stat reconciliation after archive races

Keep retrying optimistic project-stat writes instead of returning a
stale document after three lost CAS attempts, and retry destination
project discovery after a transient distinct failure.

* Fix archive reset and project-count increment races

Leave already-archived chats open after archive-all, recount new
project conversations instead of incrementing, and skip a delayed
increment when a concurrent refresh already recorded that chat.

* Recover destination projects after discovery retries exhaust

Keep committed conversation IDs when post-archive distinct fails, then
rediscover those projects in finally so a moved conversation's
destination still gets reconciled after the error is rethrown.

* Fix archive-all recovery batching and remount pending state

Recover destination projects in 500-id chunks so the final lookup
cannot exceed Mongo's command size, and share archive-all pending
state through a mutation key so Settings remounts stay disabled.

* Stamp bulk-archived chats and refresh the pinned cache

Bulk archive wrote only isArchived, so the archived table dated every
swept chat by createdAt and the default archivedAt sort dropped the whole
run into the legacy null group. Stamp one timestamp for the sweep; the
filter only matches unarchived chats, so an existing stamp cannot move,
and timestamps: false still preserves each updatedAt.

The pinned section fetches on its own key with a five-minute stale time,
so an archived pin kept rendering in the sidebar until that expired.
Invalidate it alongside the other lists on both success and failure.

Also drop the async from the failing-batch updateMany mock: its
Promise<never> is not assignable to the Query return type, while a plain
synchronous throw types as never.

* Bound archive recovery state with the sweep marker

Recovery held every committed conversation id for the life of the
request so the finally block could re-run project discovery after an
in-loop distinct gave up. Slicing that array into 500-id queries capped
the BSON command size but not the heap, so a very large history could
exhaust a worker mid-archive.

The archivedAt stamp already identifies exactly what this call
committed, so recovery is now one distinct scoped to it. That filter is
a prefix of the existing user/isArchived/archivedAt index, and the two
discovery call sites collapse into one filter-taking helper.

* Reconcile archive stats when a write outcome is unknown

A batch that commits but whose result never returns, a stepdown or a
connection drop between commit and acknowledgement, left archivedCount
at zero, so the finally block skipped both marker recovery and the stats
refresh. The chats were archived, so no retry could find them again: the
sweep filter no longer matches them and their projects kept stale
counts.

Both now key off the write attempt rather than the returned count.
Nothing else needs to change, because the marker is stamped by the same
write whose result went missing.

* Retry dropped project refreshes and guard stale pointer writes

Two ways a project could keep stale stats after archive-all.

A refresh that rejected was logged and dropped for good. Its chats are
archived, so no retry of archive-all can find them again to recompute
against, and the likeliest rejection is the recoverable one:
refreshChatProjectStatsForUser gives up when the project changed under
every compare-and-set attempt. Failures are now collected and replayed
once the rest of the run has stopped competing with them.

A save already in flight could also undo the sweep. Its conversation
document still said visible, so its tail took the pointer branch and
wrote lastConversationId back to a chat the sweep had just archived,
leaving the project advertising activity on a chat the workspace hides.
The pointer write now confirms the chat is still visible first, and
recomputes the project when it is not.

* Verify project pointers after the write, not before

Checking visibility before the pointer write only moved the race earlier:
a sweep landing between the check and the update still archived the chat
and cleared the project, and the write then restored it as
lastConversationId.

The check now runs after the write and repairs instead of preventing. A
sweep that lands earlier is caught here; one that lands later refreshes
the project itself, and refreshChatProjectStatsForUser compare-and-sets,
so it cannot commit a count it read before this write. Same single
indexed read as the check it replaces.

🗄️ feat: Record When a Conversation Was Archived (#14863)
* feat: record when a conversation was archived

The archived chats dialog has a "Date Archived" column that was bound to
createdAt, so it showed when the chat was created rather than when it was
filed away. Nothing recorded the latter.

Conversations now carry archivedAt, set on archive and cleared on
unarchive, and the column reads it. Chats archived before the field
existed have no stamp and fall back to createdAt, which is exactly what
that column already showed for them.

The archive view sorts on the new field. archivedAt is absent on every
previously archived chat, so the missing-value group is the common case
here rather than an edge case: the cursor's null handling, written for
titles, now covers both, and an absent stamp survives the cursor as null
instead of collapsing to the epoch and replaying the whole archive.

* fix: address review findings on the archived-at stamp

- Protect `archivedAt` from saveMessageToDatabase's unset sweep. Any
  persisted field missing from endpointOptions is unset, so sending a
  message in an archived chat cleared the stamp while leaving isArchived
  true, silently dropping it into the legacy fallback group.
- Order the legacy group by the createdAt the dialog displays rather than
  by last activity. The cursor's secondary key is now chosen per sort
  field, so the fallback the cell renders and the order the server
  returns cannot disagree.
- Put that secondary key in the archive index too, so paging the legacy
  group does not fall back to a blocking sort.

* fix: keep archivedAt on a redundant archive request

Opening an archived chat and hitting the archive shortcut, or retrying
the POST, sent isArchived: true again and replaced Date Archived with
now. saveConvo now stamps only on the unarchived-to-archived transition
and still clears the field on unarchive.

* fix: make archive timestamp updates atomic

* test: type the archive race spy against the driver signature

* fix: archive without an aggregation-pipeline update

DocumentDB documents no support for pipeline-form updates on any engine version,
and the repository's compatibility assessment records that a prior P0 rewrote the
three that existed. Stamping archivedAt through a $cond pipeline reintroduced one,
which would have sent every archive and unarchive to the route's 500 handler on a
supported 5.0 deployment.

The conditional stamp is now a compare-and-set on isArchived, which keeps the
transition atomic without a pipeline: only the write that finds the chat unarchived
stamps it, so a duplicate or retried archive leaves the original date alone and an
unarchive that lands first is re-stamped. Schema defaults and createdAt-on-insert
go back to mongoose's own setDefaultsOnInsert and $setOnInsert, and tenantId is
once again stripped by the tenant-isolation plugin rather than by hand.

* fix: do not report a racing archive as a missing chat

Both conditional writes of the compare-and-set miss when the archive flag flips
between them: the chat was already archived when the transition write ran and
unarchived again before the already-archived write. saveConvo returned null for
a conversation that plainly exists, so POST /api/convos/archive answered 404.

Confirm the conversation is really gone before accepting that result, and retry
the pair when it is not. An unknown id still costs one existence read and falls
straight through to the 404.

* fix: resolve a fully contended archive to the chat's real state

Alternating archive and unarchive requests can split every attempt of the
compare-and-set: each transition write sees the chat archived and each
already-archived write sees it unarchived. Exhausting the retries therefore
proved nothing about whether the conversation exists, and the no-upsert archive
route turned a lost race back into a 404.

Read the conversation once more when the retries run out and answer with its
actual current state instead.

perf: Flip the Pinned Flag Without a Full Conversation Save (#14862)
Pinning routed through saveConvo, which reads every message id for the
conversation and writes the whole array back just to set one boolean, and
can trigger a project-stats recompute on top.

None of that applies to a pin: it moves no chat between projects, changes
nothing the project workspace hides, and opens no retention window. A
dedicated setConvoPinned does the single findOneAndUpdate instead.

Measured against an in-memory MongoDB with the real message methods
wired in, on a 120-message chat: two driver commands and 3706 bytes
before, one command and 245 bytes after. The write scales with the
message count, so the gap widens on longer chats.

Archiving keeps using saveConvo, which it needs for exactly the project
stats and retention work a pin does not.

🕰️ fix: Stop Pinning and Archiving From Counting as Chat Activity (#14861)
* fix: stop pinning and archiving from counting as chat activity

Both routes went through saveConvo, which lets mongoose stamp updatedAt.
The sidebar orders chats by that field, so pinning hoisted an untouched
chat to the top of Today, and unarchiving a year-old chat dropped it
there too instead of back into its own date group.

saveConvo now takes preserveUpdatedAt, and both routes pass it. They also
pass noUpsert: with timestamps suppressed an upsert would insert a
conversation carrying neither createdAt nor updatedAt, so an unknown
conversation id is now a 404 rather than a silently created stub.

* test: pin a project's activity pointer against metadata-only saves

Review raised that preserving updatedAt could drag a project's
lastConversationAt back to the pinned chat's older timestamp, since the
incremental path $sets it outright.

That path is not reachable here: a pin carries no chatProjectId, so
previousChatProjectId stays null while the conversation has a real one,
projectMembershipChanged is therefore true, and saveConvo takes the full
recompute branch instead. This test holds that in place, with a newer
sibling conversation in the project so a regression to the incremental
path would fail it.

* fix: keep updatedAt through the retention backfill

Under RetentionMode.ALL a legacy chat with no stored isTemporary gets a
second write after the main update, and that one still had mongoose
timestamps enabled. The first archive of such a chat therefore bumped
updatedAt anyway and landed in Today, defeating preserveUpdatedAt on
exactly the old conversations it was meant to protect.

📌 fix: Fetch Pinned Chats Independently of the Chats List (#14860)
* feat: give the pinned chats section its own fetch

The sidebar's pinned section filtered pinned chats out of the paginated
chats list, which only holds the 25 most recently updated conversations.
Once 25 newer chats existed, a reload hid the pin until the list was
scrolled far enough to fetch the page it lived on.

Pins are now fetched directly via GET /api/convos?pinned=true behind a
dedicated query, so every pin paints with the sidebar regardless of where
it falls in the chats list. Pin and unpin invalidate that query, and the
shared conversation cache helpers keep it in step so a rename, delete or
archive is reflected without waiting for a refetch.

Pins stay out of the date groups, which groupConversationsByDate already
handled.

* fix: address review findings on the pinned chats section

- Drain the cursor rather than capping the pinned request at 100. Since
  pins are kept out of the chats date groups, anything this query dropped
  was invisible in the sidebar entirely, not merely further down a list.
- Apply the active bookmark filter to the pinned request and key its
  cache by it, matching the chats list beside it.
- Move a pin to the top of the section when the caller asks for it, so a
  pin that just received a message leads the way it does in the chats
  list instead of waiting for a refetch.
- Invalidate the pinned list when a conversation is unarchived, since
  archiving removes it from that cache and nothing put it back.
- Index the pinned lookup: it filters on user + pinned and sorts by
  updatedAt, which no existing compound index covered.
- Protect `pinned` from saveMessageToDatabase's unset sweep. Any
  persisted field missing from endpointOptions is unset, so sending a
  message in a pinned chat silently unpinned it.

* fix: keep the pinned cache reconciled across the other convo mutations

Second review pass on the independent pinned query.

- Fall back to the pins already loaded in the chats pages when the
  dedicated request fails. Pins are stripped from the date groups, so an
  error otherwise emptied the section and hid them everywhere.
- Restore default focus and reconnect refetching, matching the
  conversations query. A pin changed in another tab is only reconciled by
  a refetch, since that tab's mutation never touched this cache.
- Invalidate the pinned list from the mutations that can produce or alter
  a pinned chat without going through pin itself: duplicate, fork,
  import, project assignment, and shared-link deletion.

* fix: invalidate pins on tag and project-deletion changes

Third review pass, same class as the last: the pinned query is keyed by
the active bookmark filter, so changing a chat's tags can move it in or
out of that filtered set, and deleting a project unsets chatProjectId on
its chats, pinned ones included.

* fix: cancel in-flight pinned fetches when deleting a conversation

Deletion cancelled the regular and archived queries but not the pinned
one, so a pinned GET issued before the delete could resolve after the row
was stripped and write the deleted conversation back, leaving a row that
navigates to a missing chat. Restoring default focus and reconnect
refetching in the previous commit made those in-flight fetches more
likely, so this widened rather than appeared.

Cancelled on mutate, and invalidated on success since cancelling a race
is best effort.

* test: make the SSE query-cache mock key-aware

The conversation cache helpers now run a second, pinned-keyed findAll
pass. This mock ignored its key argument and always returned an
allConversations entry, so those pinned writes were attributed to
allConversations and the write-count assertions saw three instead of two.

* fix: keep pins in sync through upsert and pin-only pages

Root-level SSE updates and resumable settlement call upsert rather than
update, so the independently cached pinned row never moved or refreshed.
An all-pin first page also left the chats virtual list empty, so
onRowsRendered never asked for the next cursor.

* fix: keep pins current through SSE recovery and project delete

Resumable SSE reconciliation invalidated conversation and allConversations
only, so an independently cached pin kept stale title and order.
Deleting a project-backed pin that lived only in that cache also skipped
the project query, because the mutation never read chatProjectId there.

* fix: keep pins current after bookmark edits and failed pages

Renaming or deleting a bookmark rewrote tags on conversations but left
the tag-keyed pinned cache pointing at the old filter. An all-pin page
whose next fetch failed also retried forever because the empty-list
effect had no memory of the attempt. Unpinning a pin that only lived in
the dedicated cache removed it from Pinned without inserting it into
Chats, and later cursor pages cannot recover a row whose updatedAt just
jumped ahead of the current cursor.

* fix: keep pins visible after a failed refetch

A failed pinned refetch left React Query holding the previous list, so
the nullish fallback never ran and a newly pinned chat vanished from
both sections. Unpinning an older pin also inserted it into every
cached chats variant, including bookmark and search results it would
not match. Drop the checked-in agent task prompt.

* test: type the pinned conversation fixtures correctly

The delete mutation takes a plain string conversationId, but reading it
back off a TConversation fixture widens it to string | null. Hoist the id
into its own constant so the call site passes the real string.

Type the tag fixture as TConversationTag so it carries the required _id
and user fields the mocked resolved value expects.

* style: sort the sidebar imports to the repo order

The new pinned-section imports went in out of the longest-to-shortest
order the import sorter enforces.

* fix: keep drained pins and empty chat caches from breaking the sidebar

A pinned page failing partway through the drain rejected the whole query, so
every pin already fetched was discarded and the section fell back to whatever
the chats cache happened to hold. Publish the accumulated pins before
rethrowing so the retry renders against the partial set.

Unpinning a chat that only lives in the pinned cache reinserted it into the
chats list by spreading the first page, which is absent once removal has
filtered out the last loaded row. Rebuild that page instead, matching the
upsert path.

* fix: order fallback pins by their timestamp

The merge kept dedicated rows in Map insertion order and appended the pins
recovered from the chats cache after them. A chat pinned while the dedicated
refetch is failing is the newest pin, so the server would return it first, yet
it landed last and could sit below the section's visible 30vh. Sort the merged
set newest-first so a fallback row takes the place the server would give it.

* fix: keep the shared badge and the move-to-top order on pins

The pin response has no isShared: the flag is derived per list request by
attachSharedFlags, which only runs for the list queries. Reinserting an unpinned
chat into Chats therefore dropped its shared-link badge, because unlike an
in-place update there is no existing row to carry the flag over from. Read it off
the cached pin before the update removes that row.

The chats cache refreshes updatedAt when it moves a conversation to the top, but
the pinned cache only reordered, leaving the previous turn's timestamp on the row.
Sorting the section newest-first then put it straight back. Refresh the timestamp
there too, so the move survives the sort and both caches agree.

💬 style: Unify Message Row Layout and Edit Surfaces (#14770)
* style: Unify message row layout and edit surfaces

Route chat, share, and search messages through a shared MessageRow so
user turns render as right-aligned bubbles and assistant turns keep a
visible identity column.

Replace per-part text editors with one edit surface that keeps tools,
errors, and artifacts visible. Preserve non-text fields when saving
content parts, copy the full serialized message, and hide hover actions
that do not apply during streaming or errors.

* style: Align edit footer and lighten editor field in dark mode

Drop the divider above the user edit footer so both edit surfaces share
the same footer treatment.

Move the editor fields to surface-tertiary-alt. Light mode is unchanged
at #fff, while dark mode lifts from #0d0d0d to #2f2f2f so the field sits
above the #212121 panel instead of sinking into near-black.

* style: Drop focus border and ring from message editors

The editor fields changed border color and added a ring on focus. Keep
the border static and rely on the app-level focus handling instead.

* fix: Keep a triggered message action visible when the row is not hovered

Hover actions fade out on non-last rows, and mobile.css only restored
display and visibility for an active button, never opacity. Opening the
fork popover therefore left it anchored to an invisible trigger once the
pointer left the row. Skip the fade entirely while a button is active.

Extract the recipe the three toolbars repeated so the rule has one home.

Rework the streaming guard to the contract the toolbar now implements:
edit and fork are omitted from a streaming response rather than rendered
disabled, and the settled turn above keeps its own actions. It asserted
the removed disabled-and-transparent behaviour and its opacity check only
held because the growing response shifted the row out from under the
pointer.

* style: Trim message edit chrome and stabilize the status row

The edit surface was a titled card sitting inside the conversation: a
bordered panel with an "Edit message" heading wrapping bordered fields,
which read as a settings dialog rather than an inline editor. Drop the
card background, border and heading, and take the footer buttons down to
the small size so the editor reads as a field in the message flow. The
captured row goes from 253px to 187px.

Move "Unsaved changes" into the footer and merge the rerun hint into the
same slot. Both previously added their own row, so typing pushed the rest
of the conversation down. The slot is clamped to two lines, which stays
under the 36px button row, so the footer height holds at 36px regardless
of which message is showing.

* test: Cover message edit layout stability

Add a mock e2e spec that measures the edit footer and section boxes and
asserts they hold steady as the status text appears, for both the
single-part user editor and a multi-part response.

The multi-part case needs an assistant message with two editable parts,
so add an E2E_THINK_REPLY marker to the fake model. Its think tags are
parsed downstream by the agents stream pipeline, which yields a reasoning
part followed by a text part.

* fix: Read the fork popover open state from its store

Fork mirrored the popover state into its own useState and reset it from an
onClose prop. Ariakit 0.4 has no onClose, and React's DOM types accept the
name on any element, so it type-checked, landed on a div and never fired.
Closing by Escape or an outside click therefore left the button reading as
active until the trigger was clicked again.

Read the state from the store instead so every close path clears it.

* fix: Keep the whole toolbar visible while an action is open

Only the triggered button escaped the hover fade, so opening the editor or
the fork popover left the row as a single floating button once the pointer
moved away. Mark the active button and have every action in the toolbar key
off it, so the group stays opaque for as long as a surface is open.

The marker is a dedicated class rather than the existing `active`, which
HoverButtons pins to the edit button of every assistant message and would
hold those toolbars open permanently.

The existing guard pressed Escape to close the editor while focus sat on the
body, so the editor never closed and its assertion only held because the
sibling faded regardless. Close the editor through its own control, and drop
focus before measuring the fade now that Escape returns it to the trigger.

* fix: Withhold copy while a response is still streaming

Text-to-speech, fork and feedback were all withheld from a message that is
still generating, but copy was rendered throughout, so the button offered to
put half a sentence on the clipboard. Gate it on the same condition.

That empties the toolbar for the duration, and SubRow collapses an empty row,
so a streaming response now carries no actions at all until it settles. Both
guards encoded the old contract: the unit test asserted copy was present and
counted a single button, and the browser guard used copy as its proof that the
toolbar had mounted. The settled turn above takes over that role.

* fix: Move retry navigation to the outer edge of a user turn

A user turn is right-aligned, but its sibling navigation rendered ahead of the
actions, so the retry counter sat inboard of the icons instead of under the
edge of the bubble it belongs to. Order it last on user turns.

* fix: Ride the stream instead of chasing it

Following a generating answer went through a helper throttled at 145ms, so the
thread caught up in visible jerks rather than flowing. It now writes the scroll
position directly on each frame, which is what an answer arriving a few pixels
at a time actually needs, and glides only for the one long trip a turn makes,
when sending has to travel from wherever the reader was down to the newest
word.

Whether to follow at all is now answered by where the reader is and which way
they were going, rather than by the abort flag. `useMessageProcess` raises that
flag on any wheel at all, downward ones included, through a throttle whose
trailing call lands after the gesture has ended, so nothing timed to the
gesture could outlive it. Scrolling down to the newest word could therefore
never resume the ride, while the scroll-to-bottom button, which touches no
wheel, always could.

Arrival is judged on the scroll it produces rather than the wheel tick that
started it, because wheel scrolling is animated and at tick time the thread is
still far short of where the tick is taking it. Arriving also counts from
further out than leaving does: while an answer streams the end recedes between
the last tick and the frame that measures it, so judging arrival as tightly as
departure leaves a reader unable to catch it at all.

* fix: Reveal retry navigation on hover while an answer generates

Copy, edit, fork and read-aloud are all withheld from a response that is still
generating, which left the retry counter as the only thing rendering under a
half-written answer. It now reveals on hover there, like the actions it sits
with, and stays put on a settled turn.

* fix: Keep a refused rerun from discarding the edit

While a response is streaming, the edit action stays available on every earlier
row, and those editors see a per-message submitting flag that is false, so
Update and rerun is enabled. The send itself is still refused: ask() returns
false for the duration of the active submission. Both editors ignored that and
closed anyway, so the draft went with them and no rerun ever started.

Both rerun paths now check the result and leave the editor untouched when the
send is refused, so the work survives until the thread is free.

* fix: Let an upward gesture beat the pending send glide

Sending arms a smooth glide down to the newest word, and the landing re-pins the
thread to the bottom. The landing was scheduled two ways, on scrollend and on a
700ms fallback, and neither was ever cancelled. A reader who changed their mind
and headed up mid-flight was pinned again regardless, then dragged back by the
next streaming resize. The fallback fires for the whole window, so this held even
after the glide had visibly settled.

The gesture now marks the glide interrupted, wherever it lets go of the bottom,
and the landing stands down when it sees that. A glide the reader leaves alone
still re-affirms the ride.

* fix: Fade retry navigation on every streaming response format

Every other action is withheld from the row that is still generating, so the
retry counter is the only thing left under a half-written answer. The plain text
row already faded it to hover-only there; the structured rows did not, and left
it sitting on its own.

Both structured paths now apply the same condition, and the class string the
three of them share moves next to the hover action styles it belongs with.

* i18n: Correct the copy the edit surface rewrite left behind

The multi-part hint told the reader to save first and then rerun, but a save
closes the editor and reopening seeds the drafts from what was just saved, so
there is nothing left to rerun and the button stays disabled. Rerunning carries a
single edited section by design, so the hint now states that limit rather than
pointing at a step that is not there.

Drop com_ui_save_submit as well: the per-part editor that used it is gone.

* test: Make the message visual baselines opt-in

The suite asserts sixteen screenshots and the repository tracks none, so
Playwright's default treats every one as a miss and the mock e2e job fails on
Linux. Baselines only compare cleanly against the machine that produced them, and
nothing here can generate ones that match the runner image.

The flows keep running and asserting their structure, which is where their value
was; only the pixel comparison is now gated behind E2E_VISUAL_SNAPSHOTS.

* style: Restore import order in the reworked message files

The repository sorter and CI disagreed with what these files were left holding
after the edit surface rework. No behavior change.

* test: Follow the reworded rerun hint in the edit layout spec

The multi-part hint was restated in the previous commit; this assertion still
expected the old wording and would have failed the mock e2e suite.

* fix: Leave the send glide alone while the answer streams in

Every delta of an answer reruns the scroll effect, and the plain follow writes
scrollTop outright, which cancels an animation on its first frame. So the glide a
send starts was killed by the first token to arrive and the reader was snapped
down instead of carried.

The follow now stands down while a glide is travelling, which is what the hook
already documented but only enforced on the resize path.

* fix: Write a saved edit onto the thread as it stands

An earlier turn stays editable while the newest answer streams, and the save
captured the thread before the request but wrote it back after. Every delta that
landed during the round trip was overwritten. Most of the time the next delta
re-merged and the damage showed as a one-frame truncation, but a save that
resolved after the stream's final write left the cache wrong for the rest of the
session.

The thread is now read once the request has resolved, which is what the content
part editor already did.

The editor actions in this file also wrap again rather than hold one unbreakable
row, for the reason given in the following commit.

* fix: Let the editor actions wrap on a narrow row

At 320px an assistant turn gives the editor about 252px once page padding, the
identity column and the row gap are taken out, and Cancel, Save and Update &
rerun need more than that in English alone. The group was pinned with shrink-0,
so it ran past the edge of the row instead of wrapping. A longer translated label
makes it worse, and the user turn had no margin left either.

Both editors wrap again, which is what the footer did before the status row was
folded into it.

* fix: Catch up to the new bottom when the glide lands

Following stands down for the length of the glide, so an answer that arrives
while it travels moves the bottom past the target the glide aimed at. A short
response that finished before the glide reported landing left the thread a few
lines short of its own end, with nothing left to correct it.

Landing now closes whatever gap opened, unless the reader took over on the way.

* test: Follow the renamed rerun button in the edit flow specs

The button became 'Update & rerun' when the edit surfaces were unified, but two
edit-flow specs still located 'Save & Submit' and would have waited for it until
they timed out. A type comment named the old button too.

* fix: Judge the first thread scroll against a real position

The direction check seeded its last-position ref at 0, so the first scroll
event on an opened thread, which arrives carrying a large positive
scrollTop, read as a jump downward. Near the end that cleared the abort
flag and re-pinned a reader to the stream they were scrolling away from.

Take the first event as a baseline and judge direction from the next.

* fix: Hold the content part editor to what it replaced

EditContentParts took over from EditTextPart and left two of its behaviors
behind.

An emptied box now blocks Save and rerun instead of persisting a blank
part. EditTextPart refused the same edit through its form's required rule
and the sibling EditMessage still does, so both editors hold one line. The
keyboard shortcuts reach the save paths directly, so they are guarded
there too, and the footer says why the buttons are down.

The editor also follows the chat direction again, taking dir and text
alignment from the same setting EditMessage reads.

* fix: Hold the footer height while a response streams

Every action is withheld from the row that is still generating, and a lone
sibling counter renders nothing, so the footer measured zero until the answer
landed and then sprang to the height of the buttons. The transcript stepped
upward under the reader at the moment a response completed.

The placeholder that used to reserve this space went when the footer became
unconditional, so hold the height on the row itself instead.

* fix: Remember where the thread was put before judging a gesture

Direction is judged against the last sample, and the thread is placed at its
end without the reader touching it. With no record of where it was put, their
first gesture was spent taking the baseline instead of being obeyed: a single
PageUp cleared no flag of its own, so the next streamed resize rode the reader
straight back to the end they were leaving.

Every programmatic move now records the position it left the thread at, so the
sentinel stands only until something has actually placed it.

* fix: Spend the start of a turn only once it can be honored

A reader who scrolls away during one answer leaves the abort flag raised, and
nothing lowers it until the next connection opens, which is after this effect
has already seen the send. Marking the turn as started on that first pass spent
it against a closed gate: by the time the flag cleared there was no start left
to honor, the reader was still detached, and the answer they had just asked for
streamed on offscreen.

Record the turn as started only on the pass that acts on it.

* fix: Show the part edits that survived a refused save

The editor saves every changed part through one button, but the endpoint
takes a single part per call and nothing rolls a write back. A part the
server refused therefore left the earlier ones stored while the editor
reported that the message could not be saved, so cancelling from there
walked away from edits that were already live.

Record the writes that landed and reconcile the transcript with them
whichever way the save ended. The refused parts are the only ones left
holding a draft, so a retry no longer rewrites what already arrived.

* fix: Stop a shared transcript from calling the sharer the reader

The share row reused the chat view's user label, which reads "You". It is
the screen-reader heading for the user turn, so anyone opening a share
link heard every prompt the sharer wrote credited to themselves.

Use the neutral "User" label on this surface. It keeps the localization
the row gained, unlike the untranslated string it replaced.

* fix: Let go of the stream when an interaction settles over several resizes

Expanding a tool result mid-answer renders the container first and fills it
once its contents arrive, so one gesture produces more than one resize. Only
the first was credited to the interaction. The second read the reader as still
riding the stream and put them back on the bottom they had just left.

The suppressed resize now settles the ride as well as the near-bottom measure,
using the position the interaction actually left the reader at, so an
interaction that kept them on the end still streams.

* fix: Edit inside a structured text part instead of flattening it

A text content part holds either a string or a { value, annotations } object.
The Assistants thread sync persists the structured form with its file
citations intact, and the editor reads the part through the same union, so
saving an edit wrote a bare string over the whole object and took every
citation with it.

The same object was handed to the tokenizer, which measures length, so a part
that had been edited this way also stored a NaN token count. Write the edit
into value, keep the rest of the part, and count the text itself.

* fix: Keep a saved part's citations in the transcript it is written back to

A text or think part holds either a bare string or a { value, annotations }
object, and the editor already read both through getPartText. Writing the
draft back into the local message cache put the string over the whole value,
so a response carrying file citations lost them the moment it was edited and
did not get them back until a refetch.

Reading and writing now go through the same accessor, so an edit lands in the
shape it was read from and the rest of the part survives.

* fix: Let the message editor follow the chosen font size

Editing a message dropped the draft to a fixed 14px regardless of the
Font Size setting. On dev the textarea carried the markdown class, so it
read --markdown-font-size like the rendered message does; restyling it
into a bordered box replaced that with text-sm, and the new per-part
editor was written the same way. Anyone on Extra Small, Large or Extra
Large saw the text jump the moment they entered edit mode.

Share the .message-content typography with the editors through a
message-editor-text class so a draft is sized like the message it
replaces and keeps tracking the setting.

🔗 feat: Shared Conversation Badge and Stable Share Links (#14712)
* feat: improve shared conversation links

* test: Cover Shared Link Lifecycle

* test: Cover Shared File Snapshots

* fix: address review findings on shared links

Stop double-decoding the conversation search term. Express already decodes
req.query, so the route's extra decodeURIComponent threw URIError on any term
containing a bare percent sign and mangled percent-escape-looking text. The
sidebar already sent the term raw, so this failed there too.

Advance a share's stored target to its branch tail when an update omits one.
Updating from the conversation list could not resolve the tail and reused the
stored target verbatim, silently republishing the same snapshot instead of the
turns added since.

Require revalidation on shared files. Updates now keep the shareId, so the file
URL no longer changes and a cached response could outlive a revoked share-files
choice; an ETag over the pinned snapshot fields keeps unchanged files on 304.

* fix: keep the shared badge across conversation cache replacements

isShared is derived per list request and absent from single-conversation
payloads, so rename, pin, and the SSE conversation updates dropped it when they
swapped a server response into the sidebar cache, hiding the badge until an
unrelated list refetch. Carry the cached value forward in updateConvoInAllQueries
so every replacing caller is covered, while an explicit value still wins.

* test: mock syncStaticTools in server boot specs

initializeMCPs now calls syncStaticTools when no MCP servers are configured, but the server boot specs stub ~/server/services/Config without it. Post-listen initialization threw, hit process.exit(1), and took the jest worker down until it exceeded the retry limit.

* fix: address codex findings on the shared DataTable and file ETag

Keep the published DataTable export bound to the legacy component and ship the design-system table as VirtualizedDataTable, so external consumers of @librechat/client keep the props they compile against.

Fold the snapshot's stored location into the shared-file ETag, so a re-published output that keeps its size and revision but moves its object no longer revalidates to a stale 304.

Auto-fill the table when a first page is too short to overflow its container, since pagination is otherwise only reachable through the scroll handler.

* fix: re-scope share grants before publishing and retry stalled auto-fill

Move the shared-link ACL expiration write ahead of the content update. The shareId survives an update, so a failed ACL write after the write-through left the new messages and file snapshot readable at the same URL while the owner saw a 500.

Retry a rejected auto-fill fetch up to three times: an unscrollable table has no scroll event to fall back on, and the sentinel alone would strand it on the first page.

* fix: follow regenerated branches and pin forks to the payload they saw

advanceTargetToBranchTail only walked descendants, so a target replaced by a regeneration (a sibling, not a child) left the update parked on the obsolete branch and published none of the turns that followed. A childless target now hops once to the newest sibling the conversation continued under.

A shareId survives an update, so an owner republishing between a viewer's load and their Continue click would resolve targetMessageIndex against different messages. The fork request now carries the payload's updatedAt and is rejected with 409 when it no longer matches; the viewer gets the current version pulled in and can retry.

* fix: keep table sorting and legacy backfills from breaking share flows

Restore the union formatting a local lint-staged prettier collapsed in data-provider types, which broke the CI lint run.

Header clicks now toggle direction instead of cycling through an unsorted state, which the controlled tables translated straight back into the default and made one direction unreachable.

Re-arm the auto-fill guard on a sort change: a re-sorted first page arrives with the same row count, and the guard would otherwise suppress paging on a container that still cannot scroll.

Lazy fileSnapshots backfills no longer touch updatedAt. That timestamp is the revision a viewer's fork is validated against, so a legacy share's first read would have made the Continue click that followed it fail with a 409.

* fix: break pagination ties by id and reset share state per conversation

Both list cursors marked a page boundary with values that repeat: conversations by (sort field, updatedAt) and shared links by the sort field alone. Imported chats share a title and a timestamp, so every row tied with the boundary was skipped. Both now carry the boundary row's _id and sort by it last, and the shared-links cursor is an opaque composite the route still validates before querying.

The share dialog outlives a switch between conversations, so a link with files disabled left the next conversation's dialog showing the switch off and quietly published without files. The stored choice now falls back to the enabled default, and a stale link no longer sits in the copy field.

* fix: keep titleless shared links in the paginated list

A share has no title default, and BSON orders a missing title before every string, so encoding the boundary as an empty string skipped the remaining untitled links when sorting Name ascending and re-admitted all of them descending.

The cursor now carries the boundary's null rather than flattening it, and because $lt and $gt are type-bracketed against a string, descending adds an explicit clause for the untitled tail that a string comparison can never reach.

* style: sort share method imports

* fix: fail closed on orphaned share targets and guard snapshot backfills

getMessagesUpToTarget walked levels from the roots and returned everything it had accumulated when the target was never reached. An imported or partially deleted branch whose parent is missing therefore published the whole conversation instead of the selected branch; the walk now returns nothing unless it actually reaches the target.

A lazy backfill wrote fileSnapshots unconditionally, so a viewer's first read of a legacy link could land after a republish and restore the snapshot it replaced, re-authorizing the stable URL of a file the owner had just removed. The write is now conditional on the link still having no snapshot, and the stored one wins any race.

Regenerating a message above the shared tail leaves the whole stored branch childless, so the target walk now climbs to the closest ancestor the conversation continued under instead of stopping at the stored tail's own siblings.

Changing the search or sort also returns the table's viewport to the top, since the query holds the previous rows while it refetches.

* fix: page through titleless rows on both sides of the cursor

The route validator still required a string primary, so the composite cursor the data layer issues for a titleless boundary came back as a 400 and the shared-links table stopped at that page.

Conversations had the same type-bracketing gap the shared links just closed: a name-sorted page could not reach conversations with no title, since a comparison against a string never matches a missing field. The cursor now carries the null and the filter spells out the titleless clauses for both directions.

* fix: keep the share badge read-only and refresh rows on cell changes

ensureLinkPermissions re-granted the owner ACL entry on every call, so rendering the header's shared badge turned ordinary navigation into a permission write. It now checks for the grant first and only migrates a link that still lacks one.

A fork carrying a positional target but no revision falls back to the whole share, since nothing proves which payload the index was counted against.

The memoized table row compared row data and selection only, so a cell rendering external state (the archived list's pending Restore, for one) kept its stale rendering until the row object itself moved; rows now also compare a marker that moves with the column definitions.

* fix: keep the shared badge honest when a delete fails or a link remains

A failed delete left the conversation looking unshared: the optimistic snapshot covered only the shared-link queries, not the conversation caches the badge reads. The cleared conversations are now restored with the rest.

A conversation can hold one link per target message, so clearing the badge on delete is a guess. The conversation list is invalidated once the mutation settles, letting the server decide from the links that are actually left.

* fix: refetch every cached conversation page after deleting a link

The invalidation was pinned to page zero, so a conversation cached further down the sidebar kept the badge the optimistic update had already cleared even when another targeted link survived.

* fix: treat a failed page fetch as a failed auto-fill

React Query resolves fetchNextPage with an error result instead of rejecting, so the rejection handler never ran: the guard stayed armed on the unchanged row count and an unscrollable table could never reach the next page.

* refactor: move the share request helpers into the typed backend

Cursor validation, page-size clamping and the shared-file cache validator were plain backend logic sitting in the legacy JS route. They now live in packages/api with their own tests, and the route keeps only the Express-side wiring: reading query params, mapping domain error codes to status codes, and writing the response.

Also carries the requested file choice into the cache entry the create and update mutations synthesize, since the response never echoes it and the dialog reads a resolved entry with no choice as the enabled default.

* fix: hold auto-fill while the replacement page is in flight

A search or sort swap keeps the previous rows and hasNextPage on screen while the new first page loads, so the re-armed auto-fill asked for page two against a query that was still fetching its first. An infinite query runs one fetch at a time, so that request could cancel or interfere with the one already out. Both tables now pass their fetching state and the guard waits for it.

* fix: stop advertising links a deployment no longer serves

The sidebar badge rendered from the derived flag alone, so a deployment that turned shared links off still told owners a link was live while the public routes were unregistered.

The share dialog called the link a snapshot, but the payload populates the referenced message documents on every request: an edit to an already-shared message is visible immediately, and Update only adds newly referenced ones. The copy now says that.

Scroll pagination inspects a resolved error the way auto-fill already does, since React Query reports a failed page that way instead of rejecting.

* a11y: gate the shared conversation label on the feature flag

The icon stopped rendering when a deployment turns shared links off, but the row still announced the conversation as shared to screen readers. Both now read the same condition.

* fix: accept long title cursors and stop badge work the feature disables

The cursor cap was tight enough that a Name-sorted page ending on a long title produced a nextCursor the next request rejected, stranding the rest of the list. It now sits well clear of anything the server can issue.

The conversation list skipped straight into the shared-link lookup even where ALLOW_SHARED_LINKS is off, paying a round trip on the sidebar's first page for a badge that is never rendered.

A regeneration is newer than what it replaced, so only a newer sibling counts: an older one that still has follow-ups is the branch the target was regenerated away from, and resuming there published turns the target had excluded.

* fix: hold scroll pagination while a replacement page loads

Resetting the viewport to the top after a search or sort change fires a scroll event, and the retained previous rows still report another page, so the handler asked for page two of a query that was still loading page one.

* fix: keep the legacy share migration ahead of the owner-grant shortcut

A legacy row keeps its marker until every grant it needs exists, so an owner grant on its own is not proof the migration finished. Reading the marker first means a half-migrated public link still gets its public grant, while a fully migrated one keeps the read-only settled path the badge lookup depends on.

🔗 fix: Normalize MCP Tool Keys at Every Producer, Resolve Raw Names via Aliases (#14553)
* 🔗 fix: Normalize MCP Tool Keys at Every Producer, Resolve Raw Names via Aliases

Tool keys had two spellings that could diverge for any server whose name
contains characters outside [a-zA-Z0-9_.-]: the tool cache (and registry
inspector) built keys with the RAW server name, while runtime instances
are named with normalizeServerName(serverName). Three code comments
already asserted "tool keys embed the normalized server name" - no
producer honored it. For a special-character server that meant:

- definitions-only mode shipped raw def names the model echoed back,
  but the executor's tool map held the normalized instance name, so
  every call failed with "Tool not found";
- per-tool tool_options (defer_loading / allowed_callers /
  run_in_background / describe_intent) were persisted under raw keys
  that never matched the definition names the option passes resolve
  against, so builder settings were silently inert;
- tool-key parsing against normalized candidate lists silently fell
  back to last-delimiter splitting, which mis-parses delimiter-bearing
  tool names.

The reconciliation is one contract enforced in three moves:

1. PRODUCERS NORMALIZE. The tool cache (packages/api/src/mcp/tools.ts)
   and the registry inspector build keys with the normalized server
   name, matching the instance names MCP.js has always assigned. The
   builder's tool ids, agent.tools entries, tool_options keys, and
   definition names all flow from these keys, so every model-facing
   name now agrees. The cache STORE stays keyed by the raw config name.

2. CONFIG LOOKUPS RESOLVE ALIASES. New shared helpers in data-provider
   (buildServerNameAliases, normalizeMCPToolKey) map a parsed
   normalized name back to the raw config name that the registry,
   config maps, tool cache, and plugin-auth rows are keyed by. Applied
   in the definitions loader closure, handleTools grouping,
   createMCPTool's parsing fallback, getUserMCPAuthMap, and the MCP
   tools endpoint - matching both spellings so legacy raw keys keep
   resolving.

3. LEGACY DATA HEALS AT ONE BOUNDARY. initializeAgent rewrites
   raw-keyed agent.tools entries and tool_options keys to the
   normalized form (normalizeAgentToolKeys) before anything consumes
   them, so agents persisted under the old convention load their tools
   AND have all four per-tool options honored. Placeholder and
   server-pin tokens stay raw - they are config-identity references,
   not model-facing names.

Servers whose names are already in the safe character set (the common
case) produce byte-identical keys before and after; the fast path
allocates nothing. Stale Redis-cached raw keys self-heal via the
existing reconnect-on-missing path within one cache cycle.

* 🧯 fix: Deterministic Alias Collisions + Raw Names in Definition Metadata

Two review findings on the normalization contract:

- Two configured server names that normalize to the same segment (e.g.
  'Sales Force' and 'Sales:Force' -> 'Sales_Force') produce inherently
  ambiguous tool keys; the alias map silently resolved last-wins, so a
  tool selected from one server could execute against the other's
  config. buildServerNameAliases now resolves collisions to the FIRST
  configured name deterministically, and resolveMCPServerContext warns
  once per colliding pair per process so the operator can rename one
  server. A collision-resistant identifier would change every existing
  tool key, so detection + stable routing is the right treatment here;
  startup-time config validation can follow separately.

- The definitions loader resolved parsed (normalized) server names to
  raw only inside the ToolService closure, while the definition
  metadata (serverName -> mcpRawServerName) kept the normalized value.
  Server instructions are keyed by raw config names, so a
  special-character server's instructions were silently omitted in
  definitions-only mode. loadToolDefinitions now takes rawServerNames,
  resolves the boundary against both spellings, and stores the RAW
  name in definition metadata - consistent with the instance path.

* 🧯 fix: Heal Stale Caches, Skill Allowed-Tools, and Builder Selectors

Three review findings on the normalization rollout, all in the
transition class:

- Stale cache entries (P1): the definitions-only loader treats the
  per-server tool map as authoritative and never reconnects on a
  per-key miss, so a pre-change raw-keyed Redis entry would make a
  special-character server's tools vanish for up to the cache TTL.
  getMCPServerTools now heals legacy raw-keyed entries to the
  normalized format at read time (keys and function names), covering
  every consumer with no coordinated invalidation; safe names return
  the map untouched.

- Skill allowed-tools: a skill declaring a raw MCP key in
  allowed-tools bypassed the initialize-boundary heal (the union runs
  after it) and would neither dedupe against healed agent tools nor
  match the normalized tool map. The primes' allowedTools now pass
  through the same normalizeAgentToolKeys heal before unioning.

- Builder selectors: matchesMcpServer and useVisibleTools parsed tool
  ids against raw server names only, so an attached special-character
  server rendered as an unselected orphan card. Both now accept the
  normalized spelling and resolve it back to the raw map key, keeping
  legacy raw ids working.

* 🧯 fix: Fail Closed on Normalized Server-Name Collisions

Escalation of the collision finding: a deterministic first-wins alias
plus a warning still let the tools listing publish BOTH colliding
servers, so a tool selected under the shadowed second server would
silently execute against the first server's configuration (their
model-facing keys are identical, so routing cannot ever distinguish
them).

- findShadowedServerNames identifies later-configured names whose
  normalized form an earlier different name claimed.
- getMCPTools excludes shadowed servers from the published listing
  entirely (with a warn naming the collision), so their tools are
  never selectable - nothing ambiguous can be picked.
- Server creation reserves both spellings: a generated slug may not
  collide with a raw config name OR the normalized form its tool keys
  would carry.

Collision-resistant model-facing IDs remain out of scope: changing
normalizeServerName's output would rewrite every existing tool key
(agent documents, caches, instance names) for ALL servers to handle a
misconfiguration that is now blocked from exposure instead.

*  fix: Dedupe Reserved Server-Name Spellings at Creation

The reservation list appended normalized forms unconditionally, which
duplicated every safe name (raw === normalized) and broke the
route-level contract test pinning the exact list. Dedupe via a Set so
safe names contribute one entry, while special-character names still
reserve both spellings; adds the special-character reservation case.

* 🧯 fix: Never Heal a Shadowed Server's Keys; Align Authorization Tie-Break

Persisted references were the remaining collision vector: an agent or
skill saved with the shadowed later server's raw key was HEALED into
the shared normalized key, authorized through a last-wins map, and
routed first-wins - authorized as one server, executed as another.

- normalizeAgentToolKeys now refuses to rewrite keys of shadowed
  servers (findShadowedServerNames): rewriting would produce exactly
  the first server's key. Left raw, the key cannot match the
  normalized-keyed tool map and the tool fails visibly - broken beats
  misrouted. Covers agent.tools, tool_options, and skill
  allowed-tools through the shared heal.

- filterAuthorizedTools (agents/v1.js) builds its normalized-to-raw
  map via the shared buildServerNameAliases instead of a last-wins
  Map constructor, so authorization resolves a colliding key to the
  SAME first server execution routes to.

* 🧯 fix: Direct Identity Wins Over Aliases; Heal Client Forms and Degraded Contexts

Four review findings on the normalization edges:

- Alias hijack (P1): a user-DB server named exactly like an operator
  server's normalized form ('foo' vs YAML 'foo!') had its tools
  rerouted to the operator server by unconditional alias resolution.
  Resolution is now DIRECT-FIRST everywhere: the parsed name is tried
  as-is, and only when nothing resolves is it treated as a normalized
  spelling (definitions loader, handleTools grouping, createMCPTool
  fallback). buildServerNameAliases seats identity entries before
  derived ones so a literal name owns its slot regardless of config
  order, findShadowedServerNames and the collision warning derive from
  the same construction, and getUserMCPAuthMap fetches auth under both
  spellings so either owner finds its rows.

- Builder double-match: a normalized name containing the delimiter
  ('foo mcp bar' -> 'foo_mcp_bar') also suffix-matched a server named
  'bar', selecting both cards and making removal strip the wrong tool.
  matchesMcpServer now resolves the token ONCE against the full
  configured list (longest boundary, both spellings) when the caller
  supplies it; selection and removal share the resolution.

- Builder legacy ids: an agent saved with raw-keyed ids showed its
  tools unchecked while the runtime heal kept them active, and
  selection updates never replaced the legacy entries. McpSection maps
  legacy raw ids to their current normalized ids when deriving and
  rewriting this server's selection.

- Degraded context: a transient ensureConfigServers failure returned
  an entirely empty context, leaving normalized keys unresolvable for
  the request. resolveMCPServerContext now keeps the name lists (they
  derive from the config snapshot alone) and degrades only the
  lazy-init configs.

* 🧯 fix: Collision Detection Sees Accessible Servers; Shadowed Refs Fail Closed End to End

Round follow-ups on the collision design, all in the
DB-server-visibility class:

- The legacy-key heal detected collisions against operator-config
  names only, so healing could still produce a key that direct-first
  resolution routes to an invisible user-DB server. initializeAgent
  gains an optional getAccessibleMcpServerNames dep (wired through
  ToolService for controllers that mock it, directly elsewhere),
  consulted ONLY when a configured name needs normalization - zero
  cost for safe-name deployments. The heal then sees the full
  accessible set and skips shadowed servers' keys.

- Wildcard and legacy raw tokens bypassed catalog filtering, letting a
  shadowed server's instances join a run under the same normalized
  names as the winner's. filterAuthorizedTools rejects tools of
  shadowed servers at authorization (its merged map sees DB + config),
  and handleTools skips them at execution.

- The builder migrated only tool selection, not tool_options: legacy
  raw option keys showed disabled while the runtime honored them, and
  toggles could not clear them. McpSection now migrates option keys to
  the current normalized ids (existing normalized entries win).

- A transient ensureConfigServers failure degraded to an EMPTY server
  context, leaving normalized keys unresolvable for the request.
  resolveMCPServerContext keeps the name lists (derived from the
  config snapshot alone) and degrades only the lazy-init configs.

* 🧯 fix: Complete the Collision Audit at Every Gate; Safer Heal Semantics

Round follow-ups hardening the collision audit:

- Execution guards now consult the FULL accessible set: the caller's
  heal threads its already-fetched names through loadTools, and
  handleTools fetches them itself when a configured name needs
  normalization (never for safe-name deployments) - so a cross-tier
  collision (user-DB 'foo' vs operator 'foo!') fails closed at eager
  execution instead of joining the run under one normalized name.

- Healing is SKIPPED when the collision audit cannot complete
  (transient lookup failure, or no dep): un-healed raw keys still
  resolve through the direct-first candidates, so skipping is safe
  while rewriting against an incomplete audit is not.

- The audit lookup is gated on the agent actually carrying
  delimiter-bearing keys (tools, tool_options, or skill
  allowed-tools), so non-MCP agents never pay a registry round-trip
  even on specially named deployments.

- normalizeAgentToolKeys gives the CURRENT (normalized) entry
  precedence when both spellings carry options, matching the builder's
  migration semantics instead of letting insertion order decide.

- The builder's toCurrentToolId resolves entries boundary-exactly
  against every configured server (longest match, both spellings), so
  a raw suffix shared with a LONGER server name can no longer reassign
  that server's selection or options while another dialog is open.

* 🧯 fix: Shared Collision Audit for Definitions Loading; Fail Closed on Audit Failure

Round follow-ups closing the remaining audit gaps:

- The definitions-only loader now consumes the same collision audit as
  eager loading: shadowed servers' entries (wildcards included) are
  dropped before definitions are emitted, so the default execution
  path can never resolve a shadowed server's normalized function name
  to another server. The audit names thread from initializeAgent's
  heal; the loader self-fetches only when a configured name needs
  normalization.

- resolveCollisionAuditNames centralizes the audit-resolution policy
  (threaded set > self-fetch when needed > incomplete on failure), and
  BOTH loaders now fail closed under an incomplete audit: any
  normalization-sensitive reference (its own name needs normalizing,
  or it equals the normalized form of a configured special-character
  name) is skipped with a warning instead of being audited against
  operator names alone. isNormalizationSensitiveName lives in
  packages/api as a pure helper so test mocks use the real predicate.

- normalizeAgentToolKeys collapses duplicate ids after healing
  (order-preserving): a document carrying both spellings converges on
  one key, never two instances with the same function name.

* 🧯 fix: Thread the Audit Everywhere; Identity-Aware Alias Fallback

Round follow-ups on audit plumbing:

- The OpenAI-compatible and Responses tool loaders now forward the
  already-resolved accessibleMcpServerNames instead of discarding it,
  so the definitions loader neither repeats the registry lookup nor
  fails closed on a transient second lookup after the first succeeded.

- The skill-only path threads its audit: when the baseline agent has
  no MCP keys but a primed skill's allowed-tools fetched the complete
  set, that set (not the operator-only list) reaches the loader, so
  the collision remains visible and the shadowed reference stays
  rejected end to end.

- OAuth discovery iterates the collision-FILTERED tool list, so a
  request can no longer emit an OAuth prompt, wait out the connection
  timeout, and reconnect a server whose definitions were deliberately
  rejected.

- The definitions loader's alias fallback is identity-aware: when the
  parsed name IS a known accessible server, a null tool fetch means
  temporarily unavailable (OAuth pending, missing user variables,
  disconnected) and no longer reroutes to the raw alias - previously
  the aliased operator server's definitions could be emitted under the
  unavailable DB server's names.

* 🧯 fix: Legacy-Key Definition Lookup; Retain Audit for Deferred Execution

- createMCPTool resolves tool definitions by BOTH spellings: the key as
  persisted plus the canonical normalized key built from the resolved
  server name. Assistants and direct tool calls persisted before the
  rollout bypass the agent-boundary heal and arrive with raw keys, while
  availableTools is now indexed canonically - previously every such call
  missed the index, burned a reconnect, and returned the unavailable
  stub permanently via the negative cache.

- The initialized agent retains accessibleMcpServerNames (the COMPLETE
  collision audit this initialization resolved), buildAgentToolContext
  copies it into every per-agent tool context, and loadToolsForExecution
  threads it into the eager loader as bare options. Deferred/event-driven
  execution therefore reuses the snapshot instead of repeating the merged
  registry read - a transient failure there could fail-closed a tool the
  same turn already advertised from the successful first audit.

- MCP.spec.js keeps @librechat/api pure helpers REAL (requireActual
  spread) so normalization paths are exercised rather than mirrored.

* 🧯 fix: Parse Legacy Keys Against Both Server-Name Spellings

createMCPTool's boundary candidates were normalized-only, so a legacy
raw key whose server name contains the delimiter (foo_mcp_bar!) missed
the suffix match and fell to the generic last-delimiter split - the
canonical rebuild then produced a key that could never hit the index
and the persisted call stubbed out. The candidate list now carries the
RAW resolved name (and raw config names on the parse-only path) next
to the normalized spellings.

* 🧯 fix: Honest Audit Completeness; Shadowed-Server Form-Key Guard

- resolveAllMcpConfigs tolerates ensureConfigServers failures, so the
  merged registry read can silently omit config-only servers while the
  audit still reported complete: true - a foo/foo! collision would go
  unseen and a persisted key could route to the wrong server. Both
  audit consumers now union the snapshot-derived raw config names back
  in (resolveCollisionAuditNames unions the caller's rawServerNames;
  the initializeAgent heal unions configRawServerNames), keeping the
  completeness label honest without an extra read: operator names come
  from the registry-independent config snapshot, user-DB names from the
  merged read that fails loudly into the existing incomplete path.

- The client tool_options migration now mirrors the runtime heal's
  fail-closed rule for SHADOWED servers: when the dialog's server has
  lost its normalized slot to another catalog name, legacy raw keys
  stay raw instead of being rewritten onto the winning server's key,
  where a later save would apply the wrong server's per-tool settings.
  The dialog's own server joins the alias construction so a stale
  catalog map can't misread as a collision.

* 🧯 fix: Heal Legacy Assistant MCP Tool Names on Save

The assistants create/update controllers look tools up in the cached
definitions by exact key, and the cache is now normalized-keyed - an
assistant saved before the convention resubmits its raw-suffixed MCP
name on every edit, so any save silently removed the tool.

healMcpToolNames pre-heals the payload's tool list: a delimiter-bearing
string that misses the cache resolves through the configured raw names
(longest-suffix, boundary-exact) and rewrites to the normalized key
only when that key actually exists in the cache. SHADOWED raw names
stay raw and fail closed, mirroring the runtime heal; the config read
happens only when a delimiter-bearing name actually misses, and read
failures propagate (write path) rather than silently dropping tools.
v2's update loop also stops re-reading the tool cache per iteration.

* 🧯 fix: Full-Audit Shadow Set + Dedupe in the Assistant Key Heal

- The assistant-save heal built its shadow set from operator config
  names alone, so a cross-tier collision (user-DB `foo` owning the
  normalized slot of operator `foo!`) looked unshadowed and the legacy
  key healed into the shared normalized name - which direct-first
  execution then binds to the DB server. The shadow set now comes from
  resolveCollisionAuditNames' full accessible audit, and an incomplete
  audit skips healing outright (every rewrite candidate is
  normalization-sensitive by construction, so raw-and-fail-closed is
  the only safe answer).

- Healed string entries dedupe order-preserving: a payload carrying
  both spellings of the same tool collapses to one entry instead of
  expanding into duplicate function definitions the provider rejects.

🧹 fix: Clean Up MCP OAuth State Mappings on Uninstall + Reject Superseded Callbacks (#14549)
* 🧹 fix: Clean Up MCP OAuth State Mappings on Uninstall + Reject Superseded Callbacks

Disconnecting an OAuth MCP server deleted its mcp_oauth flows but left the
mcp_oauth_state:{state} mappings behind for the full TTL. Because flow ids
are deterministic (userId:serverName) and the CSRF token is HMAC(flowId), a
stale browser tab's callback could resolve its orphaned state to the NEXT
flow for the same server, pass CSRF, burn the fresh flow's one-shot CSRF
cookie, and fail the PKCE exchange, sabotaging the legitimate retry.

- Add MCPOAuthHandler.deleteFlowAndStateMapping: reads the flow's stored
  state and deletes the mapping before the flow (mapping-first so a crash
  between deletes fails closed instead of recreating the orphan)
- Route mcp_oauth deletions in clearStoredMCPOAuthState through the helper
  for both tenant-scoped and legacy flow ids
- Reject callbacks whose state does not match the resolved flow's stored
  state: the only control distinguishing a superseded attempt from the
  current one on a deterministic flow id

Fixes #14534

* fix: gate failFlow on state match in the OAuth error branch (Codex P1)

The provider-error branch failed the resolved flow on CSRF/session alone,
so a superseded error callback resolved through an orphaned mapping could
mark the current flow FAILED. Apply the same stored-state equality gate
before failFlow.

* fix: leave the flow in place when the state-mapping delete fails (Codex P2)

deleteFlow swallows storage errors and returns false, and
deleteStateMapping discarded that result, so a failed mapping delete
followed by a successful flow delete would silently recreate the orphan.
Surface the boolean from deleteStateMapping and throw from
deleteFlowAndStateMapping before touching the flow, so the caller's
allSettled warn branch fires and the next replacement retries both.

* fix: restore the state mapping when the flow delete fails (Codex P2)

The inverse partial failure of the round-3 fix: a successful mapping
delete followed by a silently failed flow delete left a PENDING flow
whose reused authorization URL could never resolve, dead-ending every
callback in invalid_state until the flow went stale. Check deleteFlow's
result, re-store the mapping on failure, and throw so the caller's
allSettled warn branch fires.

* fix: never leave a callback-capable flow behind on uninstall (Codex round 6)

Teardown runs after the server's tokens are deleted, so a preserved
flow+mapping pair (the round-3 early-throw path) let a lingering consent
tab complete the callback and recreate credentials post-uninstall. Now
that both callback branches gate on stored-state equality, an orphaned
mapping is the benign failure mode, so invert the order: delete the flow
first, attempt the mapping delete regardless, and reject when either
reports a storage failure. This supersedes the round-4 mapping restore,
which also preserved a callback-capable pair.

* fix: delete the flow even when its metadata read fails (Codex round 7)

A storage error on the initial getFlowState aborted teardown before any
delete ran, preserving the callback-capable flow after token deletion.
Tolerate the read failure, delete the flow blindly, skip the mapping it
could not identify (the callback gates neutralize the possible orphan),
and reject so the caller's warn branch fires.

🪃 fix: Resolve User Vars Before the First Post-OAuth Reconnect (#14538)
* fix: resolve customUserVars before first post-OAuth-callback MCP reconnect

The OAuth callback route reconnects the user's MCP connection immediately
after storing new tokens, but never resolves customUserVars before doing
so - unlike the /reinitialize route a few hundred lines below, which does.
As a result, headers/oauth_headers templates like `{{MY_KEY}}` are sent
to the MCP server literally, unsubstituted, on this first connection
attempt, even though the user's value is already saved. The upstream
server rejects it as an invalid credential.

Fixes #14537

* refactor: share getServerCustomUserVars reader from @librechat/api

The mcp_-prefixed key shape was built by getUserMCPAuthMap but re-derived
by hand at each read site (a private helper in services/MCP.js, and the
new callback-route extraction). Export a reader from the same module that
owns the writer and reuse it at both sites, so the key shape has a single
source of truth.

* chore: sort destructured require members in routes/mcp.js

* feat: encrypt tenant Langfuse secret in admin config

Add generic per-field secret encryption to the admin config layer: registered
secret paths (langfuse.secretKey) are encrypted with encryptV3 on write and a
non-secret fingerprint companion is stored. Admin config reads (base + per
principal) redact registered secrets so they are never returned; the fingerprint
is kept so the UI can show which key is configured.

The Langfuse fanout read path decrypts the tenant secret before export. Adds
secretKeyFingerprint to langfuseConfigSchema and tests for the encrypt/redact
policy.

Settings (Dify-style): enable toggle, host, public key, masked write-only secret,
configured-key fingerprint, and a test-connection action. Backed by a dedicated
/api/admin/langfuse/connection endpoint that encrypts the secret at rest, returns
metadata plus fingerprint on read, and validates credentials. Builds on the
per-field encryption and fanout decrypt from the langfuse-config-encryption branch.

* refactor: align Langfuse secret field to CustomUserVars pattern

Use the established SecretInput plus Set/Unset state pill (com_ui_set/com_ui_unset)
from the MCP CustomUserVars UI for the saved-secret state, instead of a bespoke
masked input.

🧹 feat: Eager HITL Checkpoint Cleanup (Expiry + Deletion) & Full-Wiring E2E (#14123)
* feat: eager HITL checkpoint cleanup on expiry + deletion, full-wiring e2e

Follow-up to the lazy checkpointer (#14024): two paths still left a paused
run's durable checkpoint to the 24h Mongo TTL, and no test exercised the
whole HITL seam with real components.

1. Approval expiry: GenerationJobManager.setApprovalExpiredHandler(fn) — a
   non-destructive host hook fired after expireApproval's CAS succeeds
   (periodic sweeper AND stale-submit path), safe on startups that run
   constructor defaults. Both startups (index.js configureGenerationStreams,
   experimental.js) register a handler that prunes the checkpoint, resolving
   config lazily per expiry (streamId === conversationId === thread_id).

2. Conversation deletion: deleteConvos now returns the deleted
   conversationIds; the three deletion paths (DELETE /convos, DELETE
   /convos/all, account deletion) prune them via the new bulk
   deleteAgentCheckpoints (one $in deleteMany per collection). The delete
   routes gain configMiddleware for the checkpointer config.

3. Full-wiring e2e (hitlCheckpoint.e2e.spec.js): real SDK Run driven by
   FakeChatModel calling a gated tool, real PreToolUse/humanInTheLoop wiring,
   real LazyMongoSaver over mongodb-memory-server, real GenerationJobManager,
   real /resume controller via supertest. Asserts: clean turn persists
   nothing; error turn persists nothing; pause -> HTTP approve -> gated tool
   executes exactly once -> finalize prunes the checkpoint; expiry prunes the
   abandoned pause eagerly.

Tests: 3 handler unit tests (pendingAction.spec), 2 bulk-prune integration
tests (checkpointer.integration.spec), convos route + deleteUser specs
updated, 4 e2e scenarios. 207 tests green across changed areas.

* fix: tenant-scoped expiry prune, store-won expiry relay, resilient deleteConvos ids

Codex round 1 on #14123 — all three valid:

1. The approval-expired handler now receives the expired JOB so both startups
   resolve config in the paused job's tenant/user scope (getAppConfig({userId,
   tenantId})) — a tenant checkpointer override no longer sends the prune to
   the base config's collections. expireApproval fetches the job best-effort.

2. Multi-replica: when RedisJobStore.cleanupRequiresActionIndex wins the
   expiry CAS on another replica, this replica's sweeper relay branch now runs
   the approval-expired cleanup too (prune is idempotent) — store-driven
   expiry no longer bypasses the hook.

3. deleteConvos: post-delete cleanup (deleteMessages, project stats refresh)
   is now best-effort — the conversations are already gone, so throwing hid
   the deletion and dropped the conversationIds the checkpoint prune needs,
   unrecoverable on retry. Updated the existing tag-decrement-on-failure test
   to the new contract (ids still returned).

Tests: handler-receives-job, store-won relay path, ids-survive-cleanup-failure.
134 tests green across changed suites.

* fix: relay cleanup independent of cached errorEvent; enter tenant ALS context

Codex round 2 on #14123:

1. The sweeper's relay branch gated BOTH the terminal-error emit and the new
   checkpoint cleanup on !runtime.errorEvent — but a reconnect seeds errorEvent
   from the aborted job (runtime-state creation), which then suppressed the
   cleanup entirely. The emit stays gated; the idempotent cleanup now runs
   independent of the cached error, once per runtime lifetime
   (approvalCleanupRan flag — the aborted job is swept repeatedly).

2. Passing userId/tenantId to getAppConfig only keys the config cache; the
   Config query is ALS-scoped by the tenant-isolation plugin. Both startup
   handlers now ENTER the paused job's tenant context via tenantStorage.run
   before resolving config + pruning, so a tenant checkpointer override is
   honored in strict and non-strict modes.

Tests: relay-cleanup-with-cached-error (reconnect simulation), repeated sweeps
run the cleanup once. 27+4 green.

* fix: dedup expiry cleanup across winner and relay paths

Codex round 3 (P3): expireApproval ran the handler without marking the
runtime's approvalCleanupRan flag, so the next sweep's relay branch (the
aborted job outlives expiry for the completed-job TTL) ran the cleanup a
second time. The dedup now lives inside runApprovalExpiredHandler — the
single choke point both paths call — set-before-run, once per runtime
lifetime. Test: local expiry followed by a sweep fires the handler once.

🔄 feat: Continue Shared Conversations as Personal Copies (#13714)
Adds a "Continue this chat" button to the shared conversation view that forks
the shared conversation into a new conversation owned by the viewer and opens it
to continue (issue #13001).

- POST /api/share/:shareId/fork, gated by requireJwtAuth, the fork rate
  limiters, and the canAccessSharedLink ACL (view access = fork access).
- forkSharedConversation clones from the anonymized getSharedMessages payload,
  so only share-visible data is copied.
- Strips file ids from cloned files/attachments so a fork grants no more file
  access than viewing the read-only share, and honors the global shared-file
  kill switch via the snapshotFiles option.
- Reduces the clone to the viewer's active branch, located by its index in the
  shared payload (shared ids are re-anonymized per request and createdAt can
  collide, while the payload order is stable).
- Resolves config/retention, persists, and reads back under the requesting
  user's tenant, not the share owner's; canAccessSharedLink also falls back to
  a system-wide share lookup so cross-tenant public shares resolve (ACL still
  enforced under the share's own tenant).
- Resolves a usable endpoint/model from the viewer's models config instead of
  hard-coding OpenAI, so deployments without OpenAI can send the first message.
- Routes the fork's 401s (logged-out or cold-loaded viewers) through login,
  including when the refresh itself is rejected for a stale session.
- Hides the Temporary Chat toggle once a conversation has a real id, and
  portals the share-settings theme/language dropdowns above the dialog.

Rebased onto dev; collapses the share-fork feature and its review fixes into a
single commit.

* 🔗 feat: Snapshot Files for Shared-Link Attachments

Shared-link viewers could read a shared conversation snapshot but not its
attachments: file preview/download still went through the owner-scoped file
ACL (the /api/files router sits behind requireJwtAuth + owner/agent checks),
so anonymous viewers got 401s and authenticated non-owners got 403s — the
repeated `[fileAccess] denied` warnings seen for the preview poller.

Capture an immutable per-share file snapshot (embedded on the SharedLink
document, referencing the original stored object — no byte copy) at share
create/update, and serve those files through new share-scoped routes
authorized by the existing shared-link view permission (public/ACL) plus
snapshot membership, never the owner's live file ACL.

- data-schemas: fileSnapshots on the share doc; capture in create/update;
  read-time rewrite of filepath/preview to /api/share/:id/files/:fileId;
  getSharedLinkFile + lazy backfillSharedLinkFiles for legacy links
- api: GET /api/share/:shareId/files/:file_id[/download|/preview]; route
  context added to fileAccess denial logs
- packages/api: isFileSnapshotEnabled resolver (env + yaml)
- data-provider: interface.sharedLinks.snapshotFiles (default on) + client
  endpoints/services
- client: ShareContext.shareId wired to Image, preview hook, and downloads
- config: SHARED_LINKS_SNAPSHOT_FILES env override (default on)

* 🔒 fix: Address Codex review on shared-link file snapshots

Triage of the Codex review on PR #13740 (2 P1, 7 P2 — all valid):

- P1 (cross-user access): scope the snapshot lookup to the sharing user's own
  files so a message referencing another user's file_id can't widen access.
- P1 (stored XSS): the inline share-file route now serves only safe preview
  types inline (raster images/pdf); everything else is forced to attachment with
  X-Content-Type-Options: nosniff.
- Stream shared downloads by default; redirect to a signed URL only on
  ?direct=true (blob/XHR callers work without bucket CORS).
- Read preview status live from the file record (always current for deferred
  previews) and stop embedding extracted text in the share doc (16MB-limit risk).
- Only lazily backfill when the fileSnapshots field is absent (legacy), not on
  every snapshot miss.
- Backfill legacy shares before rewriting message URLs, and gate URL rewriting
  to public shares so non-public (ACL) shares keep prior behavior (img/anchor
  can't carry the bearer token).
- Frontend: only route a download through the share path when the file was
  actually snapshotted (rewritten href / filepath), else fall back.

* 🔑 feat: Authorize shared-link files for non-public shares via cookie

Extends shared-link file access to non-public (ACL) shares (Codex finding 5).
`<img>`/anchor requests can't carry the bearer access token, so non-public
shares previously 401'd on file loads. Add an optional cookie-auth fallback on
the share file routes that resolves the viewer from the `refreshToken` cookie
(or signed `openid_user_id` cookie) — the same mechanism secure image links use
(validateImageRequest) — then let canAccessSharedLink run the viewer's ACL check.

- new middleware optionalShareFileAuth (+ unit spec); applied to the three
  share file routes after optionalJwtAuth
- URL rewriting in getSharedMessages is no longer gated to public shares (the
  route now authorizes header-less requests), so files work uniformly across
  public and non-public shares; revert the now-unused req.sharePublic plumbing

* 🔒 fix: Second Codex pass on shared-link file snapshots

Addresses the follow-up Codex findings on PR #13740:

- Don't snapshot transient text-source files: FileSources.text filepaths are
  Multer temp paths the upload route deletes, so they can't be streamed —
  removed from the streamable allowlist.
- Unset stale snapshots on a disabled-feature update: updateSharedLink now
  $unsets fileSnapshots when snapshotFiles is false, so an opted-out update
  can't keep serving file ids the update dropped.
- Load tenant config after share resolution: configMiddleware now runs after
  canAccessSharedLink (which enters the share's tenant ALS context), so
  per-tenant interface.sharedLinks.snapshotFiles overrides apply to anonymous
  public views.
- Return a clean 404 when the snapshotted object is gone: resolveShareFile now
  requires the live file record and 404s if it's been deleted/expired, instead
  of letting the stream error after headers are sent (ENOENT / 500).

(The re-flagged P1 about private-viewer rewriting was already fixed in the prior
commit's cookie-auth change.)

* 🔒 fix: Third Codex pass on shared-link file snapshots

Addresses the third Codex review pass on PR #13740:

- P1: keep shared previews/files pinned to the snapshotted version. Snapshot the
  small previewRevision; resolveShareFile 404s when the live file's revision no
  longer matches (file_id reused/overwritten by a later turn), so old links can't
  surface post-share content — covers both preview text and streamed bytes.
- Honor the toggle as a kill switch: resolveShareFile 404s when snapshotFiles is
  disabled, instead of only skipping backfill, so disabling stops serving
  already-snapshotted file URLs.
- Lazy-sweep orphaned 'pending' previews to 'failed' in the share preview route
  (mirrors the owner route) so the client poller reaches a terminal state.
- Resolve the cookie-fallback user in runAsSystem so strict tenant isolation
  doesn't throw before canAccessSharedLink establishes the share tenant context.

*  feat: Per-link "share files" checkbox for shared links

Add a checkbox to the share-link dialog (checked by default) letting the user
choose whether to include the conversation's files in the shared link, with
copy explaining images/files won't be visible to viewers otherwise. Opting out
skips snapshot creation/serving for that link.

- client: ShareButton renders the checkbox gated on the new
  startupConfig.sharedLinksSnapshotFilesEnabled flag; state threads through
  SharedLinkButton into the create/update mutations as `snapshotFiles`.
- data-provider: createSharedLink/updateSharedLink send `snapshotFiles` in the
  body; TStartupConfig gains `sharedLinksSnapshotFilesEnabled`.
- api: POST/PATCH /api/share compute snapshotFiles as
  isFileSnapshotEnabled(req.config) && body.snapshotFiles !== false (admin gate
  AND per-link opt-out); config.js exposes the effective enabled flag to clients.
- en locale: com_ui_share_files (+ _description).

* 🐛 fix: Make the "share files" opt-out actually hide files

Unchecking "share files" at creation didn't hide anything: the shared message
JSON still carried each file's original (e.g. static-served) path, and because
opting out only meant "no fileSnapshots field" — indistinguishable from a legacy
link — getSharedMessages would backfill snapshots on first view whenever the
admin feature was on, re-enabling files entirely.

Fix by persisting and honoring the per-link choice:
- Store `snapshotFiles` (boolean) on the SharedLink so opt-out is distinct from a
  legacy link; set it on create and update.
- getSharedMessages computes includeFiles = adminEnabled && link not opted out;
  when excluded it strips files/attachments from the payload (no original-path
  leak) and never backfills the opted-out link.
- Surface the stored choice via getSharedLink so the dialog checkbox reflects an
  existing link's actual setting instead of always defaulting to checked.

Note: changing the checkbox on an already-created link still applies only when
the link is refreshed (which regenerates the URL) — a UX follow-up.

* 🔒 fix: Close remaining shared-link file opt-out leaks (Codex)

Follow-up to the per-link opt-out, addressing the third Codex pass:

- Honor the opt-out on the file route too: getSharedLinkFile now returns the
  link's `optedOut` choice; resolveShareFile 404s (and never backfills) an
  opted-out link, so a direct /files/:id request can't re-create snapshots.
- Make read/serve viewer-independent: the gate no longer uses the viewer's
  resolved config (isFileSnapshotEnabled(req.config)) — it uses the link's stored
  choice plus a global env-only kill switch (isFileSnapshotKillSwitchActive). A
  viewer's own interface.sharedLinks.snapshotFiles can no longer hide a link's
  files. Create/update still use the creator's config to set the per-link choice.
- Neutralize render URLs for non-snapshotted files: applyShareFileRoute now
  strips filepath/preview for any file/attachment not in the snapshot, so the
  owner's original (e.g. static) path can't be loaded through the share.

* 🔒 fix: Harden shared-file version pinning and local path handling (Codex)

- Refuse reused/overwritten file snapshots more broadly: resolveShareFile now
  refuses to serve when either previewRevision OR `bytes` changed vs the
  snapshot. `bytes` catches non-office reused outputs (e.g. code-exec
  same-filename images that lack previewRevision) and is stable across S3 URL
  refresh and the pending->ready transition. Same-size content swaps remain a
  best-effort gap inherent to the no-byte-copy design.
- Strip cache-busting query strings before local streaming: code-output images
  add `?v=...` to filepath; the share route now splits it off so getLocalFileStream
  resolves the real filename instead of a literal `*.png?v=...` path.

* 💬 fix: Clarify that file-sharing changes apply on link refresh

For an already-created shared link, changing the "share files" checkbox only
takes effect when the link is refreshed (which regenerates the snapshot). Add a
note under the checkbox, shown only when a link already exists, so the behavior
isn't surprising: "Refresh the link to apply this change — files are snapshotted
when the link is refreshed."

🔖 feat: Add Pinned Conversations (#13492)
* feat: add `convo.pinned`

We want to be able to pin convos (so users can easily find them), thus we
added a new field to the DB schema: `pinned`.

We also had to add an API method for pinning a convo. It's got thorough tests.
It's structured just like how /api/convos/archive works, only for pinning.

* feat: add 'pinned' section to conversation list

If there are any pinned conversations, they will appear above the normal
"chats" list, with a pinned icon next to them.

* feat: added pin/unpin to convo options

ConvoOptions now has a pin/unpin button which lets you change the
pin status of any given conversation.

* fix: adjust ellipsizing gradient on ConvoLink

Because it went across the whole ConvoLink, it would cover up any
children (i.e. icons) that appear after the title. However, the point
of the gradient is just to gradually make the title disappear, not
the icons.

This change places the gradient on the title only, so it achieves
the same ellipsizing effect without interfering with the display of
the child icons.

* Fixed import sorting

🔐 fix: Honor Admin-Panel MCP Allowlist Overrides Without Restart (#13814)
* 🔐 fix: Honor Admin-Panel MCP Allowlist Overrides Without Restart

MCPServersRegistry was built once at boot from getAppConfig({ baseOnly:
true }), freezing allowedDomains/allowedAddresses to YAML. Admin-panel
mcpSettings overrides were ignored by both inspection (addServer/
reinspectServer/updateServer/lazyInitConfigServer) and runtime connection
enforcement (assertResolvedRuntimeConfigAllowed), so a domain allowed only
via the panel failed inspection and never connected.

Make the registry's effective allowlists mutable and refresh them from the
merged admin-panel config: seed at boot, and re-apply on every config
mutation via invalidateConfigCaches -> clearMcpConfigCache. Both inspection
and connection paths read the same getters, so both honor overrides without
a restart. Fail-safe: current allowlists are preserved when the merged read
fails.

* 🛡️ fix: Scope MCP allowlist refresh to global config, fail-safe on DB error

Address Codex P1 review findings on the allowlist-refresh path:

- Tenant-scoped config mutations no longer push one tenant's merged
  mcpSettings into the process-wide registry singleton (read by all MCP
  connection paths), which would leak allowlists across tenants. Only
  global (non-tenant) mutations refresh the registry; tenant mutations
  still evict the config-server cache.
- The refresh read now uses strictOverrides:true so a transient DB error
  throws instead of silently returning YAML base config — preserving the
  last-known allowlists rather than overwriting them with fallback values.
  Adds the strictOverrides option to getAppConfig (default off, no behavior
  change for existing callers).

* ♻️ refactor: Resolve MCP allowlists per-request (tenant-scoped) instead of a global singleton

Supersedes the prior global-mutation approach. MCP allowlists live in
mcpSettings, which is tenant/principal-scoped admin config, so a process-wide
singleton value is the wrong model — it caused cross-tenant bleed and stale
reads.

Instead, inject a resolver (from the app layer, where the merged config lives)
that the registry calls per inspection and per connection. It reads the ALS
tenant context via getAppConfig and accepts the acting user so user/role-scoped
overrides resolve; config-source inspection (no user) resolves at tenant scope.
Falls back to the YAML base allowlists when no resolver is set or the lookup
fails, so a transient error fails to the operator baseline rather than
disabling the allowlist.

Removes the now-unnecessary setAllowlists / boot-seed / invalidateConfigCaches
refresh / getAppConfig.strictOverrides machinery.

* 🔒 fix: Scope config-source cache by allowlist; resolve OAuth allowlists per-request

Address Codex review of the per-request resolver:

- Config-source cache key now folds in the resolved allowlists, not just the
  raw-config hash. Inspection results became allowlist-dependent, so without
  this a tenant whose allowlist rejects a URL could poison the shared key with
  an inspectionFailed stub for a tenant that allows it (and vice versa). The
  tenant-scoped allowlist is resolved once per ensureConfigServers pass and
  threaded through the cache key + inspection.
- The two remaining request-time OAuth allowlist reads now use the merged
  config instead of the YAML base getters: the fallback OAuth-initiate path
  (routes/mcp.js) via resolveAllowlists, and OAuth revocation
  (UserController.maybeUninstallOAuthMCP) via the request's already-merged
  appConfig.mcpSettings. Without this, an OAuth endpoint allowed only by an
  admin-panel override was rejected while inspection/connection allowed it.

*  test: Update MCP OAuth registry/config mocks for per-request allowlists

CI fix for the Finding-12 change. The OAuth-initiate route now calls
registry.resolveAllowlists() and the revocation path reads the merged
appConfig.mcpSettings, so the affected specs' mocks were asserting the old
base-getter values:
- routes/__tests__/mcp.spec.js: add resolveAllowlists to the registry mock.
- UserController.mcpOAuth.spec.js: provide mcpSettings on the getAppConfig
  mock so revokeOAuthToken still receives the expected allowlists.

* 🧪 test: e2e proof that admin-panel MCP allowlist override takes effect

Adds a Playwright mock-harness spec for #13809. A URL-based MCP fixture
(e2e-http, streamable-http SDK server) boots inspectionFailed because its
origin is omitted from the YAML mcpSettings.allowedDomains; the spec adds that
origin via an admin config override (PUT /api/admin/config/user/:id) and
asserts the server reinitializes — exercising the real resolver path through
the backend + DB. Before the fix, reinspection used the frozen YAML allowlist
and the server stayed unreachable.

- e2e/setup/fake-mcp-http-server.js: streamable-HTTP MCP fixture (health GET /).
- e2e/playwright.config.mock.ts: boot the fixture as a second webServer.
- e2e/config/librechat.e2e.yaml: mcpSettings.allowedDomains (excludes 127.0.0.1)
  + the e2e-http server.
- e2e/specs/mock/mcp-allowlist-override.spec.ts: login → baseline reinit fails →
  apply override → reinit succeeds.

🥽 fix: Restrict MCP Server URL Disclosure to Admins, Owners, and Editors (#13784)
* 🥽 fix: Redact Non-User-Sourced MCP Server URLs by ACL Edit Permission

GET /api/mcp/servers and GET /api/mcp/servers/:serverName return MCP server configs to any caller with MCP-use permission. For user-sourced configs (DB-stored, UI-submitted), the URL is the caller's own and is intentionally disclosed. For non-user-sourced configs (YAML or config-tier, operator-defined), the URL and OAuth flow endpoints (authorization_url, token_url) are operator-sensitive: they can encode internal infrastructure hostnames and are not editable through the API.

This change redacts those fields on non-user-sourced configs unless the caller has edit authority on the resource, using the same ACL check (PermissionBits.EDIT) that the PATCH and DELETE routes already enforce via canAccessMCPServerResource. Callers with broad MANAGE_MCP_SERVERS capability bypass the per-resource check, matching the existing capability bypass in canAccessResource. customUserVars is intentionally not redacted: its values are UI hint metadata (title, description, sensitive), not user-supplied secrets; blanking it would give non-editor callers a Configure form with no field labels.

* 🥽 fix: Correct getResourcePermissionsMap import path + tighten redact comments

The MCP server redaction commit imported getResourcePermissionsMap from ~/server/controllers/PermissionsController, but that controller is a consumer of the helper, not its exporter. The canonical export lives in ~/server/services/PermissionService (which controllers/agents/v1.js already imports from). Fixes the runtime getResourcePermissionsMap is not a function failure on GET /api/mcp/servers and the four downstream route-spec failures whose config mocks lacked a source field and were therefore wrongly treated as non-user-sourced; mocks now reflect the real registry behavior (addServer/updateServer tag DB-stored configs with source: 'user'). Trims narrating JSDoc on the redact helpers and resorts the librechat-data-provider destructure by length.

* chore: import order

* 🥽 fix: Redact OAuth Revocation Endpoint Alongside Authorization And Token URLs

The OAuth-URL strip path only dropped authorization_url and token_url. The UserOAuthOptionsSchema in packages/data-provider/src/mcp.ts (line 146) accepts revocation_endpoint as another operator-configurable URL, and the OAuth handler uses it to revoke tokens; it can hold the same internal IdP hostnames the existing strip is trying to hide. Adds revocation_endpoint to the destructure so a non-user-sourced YAML/config MCP server config no longer leaks the revocation URL to non-editor callers. The existing strip url and oauth flow URLs spec is extended with a revocation_endpoint value to lock in the new field.

* 🥽 fix: Gate Shared DB Server URL Disclosure On ACL Edit Permission

source-driven URL disclosure was incorrect for shared DB-backed MCP servers. ServerConfigsDB.mapDBServerToParsedConfig (packages/api/src/mcp/registry/db/ServerConfigsDB.ts:465) sets source: 'user' on every DB-stored config it returns, regardless of who is accessing it. A user with only VIEW share on a DB server, or with agent-mediated access, was therefore treated by the redaction layer as if they owned the URL, and GET /api/mcp/servers disclosed the owner's URL and OAuth flow URLs to viewers who could not edit the resource.

The redaction is now driven purely by ACL edit authority: computeCanEditByServer routes every dbId-bearing config through PermissionBits.EDIT regardless of source; redactServerSecrets strips on !canEdit regardless of source. POST and PATCH controllers explicitly pass canEdit: true since both endpoints establish edit authority (POST creates the resource, PATCH is gated on the EDIT middleware). Legacy/ephemeral configs without a dbId still fall back to the source heuristic.

🗄️ fix: Gate Request-Scoped MCP Servers Out of Persistent Tool Cache (#13672)
* 🗄️ fix: Gate Request-Scoped MCP Servers Out of Persistent Tool Cache

PR #13626 established that request-scoped MCP servers (runtime
OPENID/GRAPH/BODY placeholders) must not use the persistent 12h tool
cache, but only gated three of five touchpoints. The panel endpoint
still back-filled the cache and the OAuth callback still wrote to it,
while agent loading read those entries ungated — pinning ephemeral
model-spec/agent toolsets to stale definitions for up to 12h.

Centralize the invariant in createMCPToolCacheService: a getServerConfig
resolver dep gates both writers and a new service-owned getMCPServerTools
read, so every current and future caller is covered. Callers that already
hold the parsed config pass it to skip resolution; the per-call skipCache
flag and duplicated call-site gates are removed in favor of the single
config-based mechanism. Resolution failures fail open to preserve prior
behavior.

* 🩹 fix: Address Codex Review on Cache Gating

- Repair getCachedTools.spec.js, which destructured the relocated
  getMCPServerTools directly from the module; its coverage now lives in
  the service-level tools.spec.ts.
- Resolve the merged (Config-tier-aware) server config in the OAuth
  callback before writing tool definitions, so the cache gate detects
  request-scoped servers supplied via admin Config overlays that the
  base registry lookup cannot see.
- Discover tools actively for request-scoped servers in the panel
  endpoint via ephemeral reinitialization: such servers have no stored
  app/user connections, so the previous getServerToolFunctions fallback
  returned an empty toolset once the cache read was gated.

* 🧵 fix: Address Second Codex Review on Cache Gating

- Resolve the merged server config before the OAuth callback reconnects,
  so the connection itself uses Config-tier overlays rather than only
  the subsequent cache write.
- Pass Config-tier candidates into the panel's request-scoped discovery,
  matching the reinitialize route: reinitMCPServer forwards configServers
  (not the provided serverConfig) to its OAuth discovery fallback.
- Document the accepted read-path trade-off: the gate resolver sees base
  configs only, all writers pass merged configs, so a pre-gating or
  overlay-divergent entry survives at most one cache TTL.

* 🚏 chore: Rework Cache Gating for BODY-Only Request Scoping

After #13673 narrowed requiresEphemeralUserConnection to BODY
placeholders, the central gate follows the predicate unchanged, but the
panel's active discovery no longer serves a purpose: the only remaining
request-scoped class cannot connect outside a chat turn, so the
reinitialization attempt would always fail at the missing-body check.
Remove that path; OpenID/Graph servers are persistent user-scoped again
and flow through the stored-connection and cache lookups as before.

Flip test fixtures that used OPENID placeholders to denote
request-scoped configs over to BODY placeholders.

* 🪟 fix: Check Config Overlays in Agent-Loading Cache Reads

The cache service's registry resolver sees only base YAML/DB configs, so
a BODY placeholder introduced by a request-tier Config overlay was
invisible to the gate on the agent-loading read path: model-spec and
ephemeral-agent expansion could read a leftover persistent entry and pin
stale concrete tool names instead of the mcp_all fresh-discovery path.

Check the raw overlay candidate inline in loadEphemeralAgent and
loadAddedAgent — a pure placeholder scan with no extra IO — and skip the
cache read when the overlay makes the server request-scoped. Widen
UserScopedConnectionConfig so raw (pre-inspection) configs qualify for
the scoping predicates, which only check key presence.

* 🧪 test: Guard Run-Scoped MCP Definition Handoff Boundaries

The original ClickHouse breaker storm regressed precisely at field
pass-through boundaries that unit tests of each end could not see:
initializeAgent dropping mcpAvailableTools from its destructure, and the
agent tool context losing it on the way into ON_TOOL_EXECUTE. Add direct
guards on both hops: the loadTools result must surface on the
initialized agent, and the captured toolExecuteOptions closure must
forward it to loadToolsForExecution.

🤫 refactor: Silent MCP OAuth Refresh on Mid-Session 401 (#13369)
* 🤫 fix: Silent MCP OAuth Refresh on Mid-Session 401

Avoids the hourly interactive re-auth prompt when an MCP server
(e.g. Azure Entra ID) returns 401 mid-session by attempting a refresh
token exchange first, and only falling back to the interactive OAuth
flow when no refresh token is stored or the refresh server rejects it.

Resolves #13364.

* fix: Use distinct flow type for silent token refresh to avoid cache hit

Addresses the Codex review on PR #13369: `attemptSilentTokenRefresh` was
reusing the `'mcp_get_tokens'` flow type, so
`FlowStateManager.createFlowWithHandler` would short-circuit and return
the same tokens cached by an earlier `getOAuthTokens` call — the very
tokens the server just rejected — without executing the forced-refresh
handler.

Switch silent refresh to the distinct `'mcp_force_refresh_tokens'` flow
type so coalescing still works but stale `mcp_get_tokens` cache entries
are not reused. After a successful refresh, invalidate the
`mcp_get_tokens` flow cache so the next `getOAuthTokens` call reads the
freshly persisted tokens from storage rather than the stale cached
value.

Add a regression test that simulates the real
`FlowStateManager.createFlowWithHandler` cache-hit behavior for
`mcp_get_tokens` and verifies the silent refresh handler still runs and
returns the freshly refreshed tokens.

* fix: Address Codex round-2 review on silent MCP OAuth refresh

Three follow-up findings from Codex on PR #13369:

1. The new `mcp_force_refresh_tokens` flow type was itself cached by
   `FlowStateManager.createFlowWithHandler`, so a subsequent 401 within
   the refreshed token's `expires_at` could re-serve the just-rejected
   token without ever re-running the refresh handler.

2. The factory's `oauthRequired` listener was removed immediately after
   the initial `attemptToConnect` succeeded, so a real mid-session 401
   emitted by `MCPConnection.connectClient` during transport recovery
   had no listener — the OAuth handled-promise would simply time out
   instead of triggering the silent refresh.

3. Routing the silent refresh through a distinct flow type broke
   coalescing with the `mcp_get_tokens` lock used by `getOAuthTokens`,
   letting two paths concurrently redeem the same stored refresh token.
   For providers that rotate refresh tokens (e.g. Azure Entra) the
   second redemption is rejected, kicking the user back into interactive
   OAuth despite a successful refresh elsewhere.

Resolution:

- Drop `FlowStateManager` from the silent-refresh path entirely. Replace
  with a process-local `inflightSilentRefreshes` Map keyed by
  `userId:serverName` that holds only the in-flight Promise (no cached
  result), so every fresh 401 after settlement triggers a fresh
  redemption while concurrent 401s for the same user/server still share
  one redemption.
- Stop calling `cleanupOAuthHandlers()` on successful initial connect,
  keeping the OAuth handler attached for the connection's lifetime so
  mid-session 401s actually reach `attemptSilentTokenRefresh`.
- Add a regression test reproducing the stale-cache scenario by faking
  the `mcp_get_tokens` cache hit and asserting silent refresh still runs
  against storage and returns the fresh tokens.
- Add a coalescing test asserting two concurrent oauthRequired events
  for the same user/server result in a single `forceRefreshTokens` call.
- Clear `inflightSilentRefreshes` in `beforeEach` to prevent
  cross-test leakage; switch the silent-refresh test mocks to
  `mockResolvedValueOnce` / `mockImplementationOnce` so leftover mock
  state cannot leak into later test cases.

Acknowledged remaining gap: the silent refresh still races
`getOAuthTokens`'s `mcp_get_tokens` flow when both run concurrently
(narrow window when an existing connection's local `expires_at` is
still valid but the server invalidated the token, and a new connection
is being created in parallel). The race is self-healing on the next
401 and documented inline.

* fix: Address Codex round-3 review on silent MCP OAuth refresh

Three more findings from Codex on PR #13369:

1. The in-flight silent-refresh promise was unbounded. If
   `forceRefreshTokens()` ever hung (slow provider, dropped TCP), the
   `inflightSilentRefreshes` lock stayed occupied forever and every
   later 401 for the same user/server joined the stuck promise instead
   of starting a fresh attempt or falling back to interactive OAuth.

2. The interactive-OAuth fallback didn't invalidate the
   `mcp_get_tokens` flow cache after persisting fresh tokens. For
   providers that don't issue refresh tokens (so silent refresh
   returns null), the old cache could still feed stale access tokens
   to the next `getOAuthTokens` call until its TTL expired — causing
   an immediate reconnect with the same just-rejected token.

3. When silent refresh failed, the handler fell through to
   `handleOAuthRequired()` whose recent-completion fast path can
   reuse a COMPLETED `mcp_oauth` flow within `PENDING_STALE_MS`. Those
   cached tokens are exactly the ones the server just rejected, so
   the connection would keep adopting them and looping on 401s until
   the cache aged out.

Resolution:

- Wrap `runSilentRefresh()` with a 60-second `withTimeout` (well under
  `connectClient`'s 120s OAuth timeout). On timeout the `.catch`
  resolves to null and the `finally` clears the in-flight entry, so
  the next 401 starts fresh and falls through to interactive OAuth.
- Extract two helpers — `invalidateGetTokensFlow` and
  `invalidateCompletedOAuthFlow` — and call them from the right
  branches: clear `mcp_get_tokens` after silent-refresh success AND
  after interactive-OAuth `storeTokens`; clear the COMPLETED
  `mcp_oauth` state (plus its CSRF mapping) before falling through to
  interactive OAuth so the fast-reuse path can't re-serve the
  rejected tokens.
- Add three regression tests: hung refresh release-the-lock under
  fake timers, completed-OAuth cache invalidation pre-fallback, and
  `mcp_get_tokens` invalidation after interactive token store.

* fix: Address Codex round-4 review on silent MCP OAuth refresh

Three more findings from Codex on PR #13369:

1. (P1) The silent-refresh in-flight lock keyed only by
   `userId:serverName`. In multi-tenant setups where two tenants share a
   userId (e.g. username-based IDs) and the same MCP server name, a
   concurrent mid-session 401 from tenant B would join tenant A's
   in-flight refresh and adopt tenant A's freshly minted tokens onto a
   tenant-B connection — a cross-tenant credential leak.

2. (P2) `invalidateGetTokensFlow` deleted the `mcp_get_tokens` flow
   state regardless of its status. When another connection was
   currently in `getOAuthTokens()` (PENDING flow) and joiners were
   monitoring it, the unconditional delete made those waiters see
   "Flow state not found" and unnecessarily fall back to interactive
   OAuth — even though fresh tokens were already being written.

3. (P2) The 60s `withTimeout` wrapping `runSilentRefresh()` only races
   the promise; it does not cancel the underlying `forceRefreshTokens`
   /  refresh-token HTTP request. If the request returned after a
   subsequent interactive OAuth had stored newer tokens, the late
   completion would `storeTokens` over the newer state. This requires
   a provider that doesn't rotate refresh tokens AND a refresh slower
   than 60s AND a successful interactive OAuth in that window — narrow
   but real.

Resolution:

- Capture `getTenantId()` into a new `factory.tenantId` field at
  factory construction time (before the OAuth handler closes over it
  outside the original request's async context) and include it in the
  silent-refresh lock key as `tenantId:userId:serverName`.
- `invalidateGetTokensFlow` now calls `getFlowState` first and only
  deletes when `status === 'COMPLETED'`. PENDING lookups are left
  alone so concurrent `getOAuthTokens` waiters via `monitorFlow` can
  still settle.
- For (3), document the race as a known limitation inline. Fully
  closing it requires threading an `AbortSignal` through
  `MCPTokenStorage.forceRefreshTokens` and the OAuth refresh handler
  to skip the late `storeTokens` after timeout — out of scope for this
  PR's surgical change.
- Add `getTenantId` to the `MCPOAuthConnectionEvents` test's
  `@librechat/data-schemas` mock so the factory constructor doesn't
  blow up under that suite.
- Add three regression tests: per-tenant lock isolation, PENDING-state
  preservation under `invalidateGetTokensFlow`, and (reused) the
  existing interactive-store invalidation test now driven through
  `getFlowState` returning the COMPLETED state.

* fix: Address silent MCP OAuth refresh review

Restore captured tenant context around token storage and OAuth fallback paths so mid-session callbacks do not lose tenant scope.

Thread AbortSignal through forced refresh and OAuth token requests, cap silent refresh by the connection OAuth timeout, and prevent timed-out refreshes from writing stale credentials after fallback.

Complete pending mcp_get_tokens flows with fresh tokens, add missing FlowState createdAt test fixtures, and cover the new tenant/abort/cache behaviors.

* fix: Tighten tenant-scoped MCP token refresh

Cap silent refresh by both the factory connect timeout and the connection OAuth wait timeout so fallback OAuth wins before the outer connect attempt expires.

Tenant-scope mcp_get_tokens flow ids for both token lookup and refresh invalidation, preventing cross-tenant flow completion or cache deletion when tenants share user ids and server names.

Add regression tests for the omitted initTimeout budget and tenant-prefixed token flow locks.
