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

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

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

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

* 🤐 fix: Strip Preconfigured Client Instances from Resume Params

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

🧰 feat: Redesign Agent Builder with Unified Tools Marketplace, Skills & Orchestration (#13952)
* feat: redesign the agent builder tools, skills, and advanced panels

Replace the stacked capability/MCP/skill/tool/action form sections with a unified tools marketplace, per-item configuration dialogs, and a consolidated Advanced panel.

- unified tools marketplace (catalog, sidebar, polymorphic cards/rows) covering built-in capabilities, plugins, MCP servers, and actions, each with a detail/config dialog
- dedicated Skills picker and a Tools section with selected-item summaries and empty states
- redesigned action editor and authentication dialog (method cards, segmented controls)
- rebuilt Advanced panel: orchestration hub (subagents, handoffs, chain), max steps, skills kill-switch, copyable agent id
- restyled version history (timeline, tool/capability counts, in-app restore confirmation)
- shared component updates (Radio, Input/Textarea, dropdown z-index, dialog primitives) and keyboard-only focus rings via useInputModality
- format-hint placeholders for tool credential fields
- sanitize numeric parameter inputs to prevent comma truncation

* feat: refine agent builder tools, actions, and MCP sections

* feat: restore Memory capability toggle in agent builder tools catalog

* feat: refine agent tools picker (skills, MCP connect/OAuth, web search)

- Skills picker: per-card visibility (public) and shared-author badges,
  category filtering, and an in-place Create skill flow that auto-attaches
  the new skill without leaving the builder
- MCP: inline Connect button in the first dialog plus a dedicated OAuth
  dialog (continue, copyable URL, QR code) shown only when OAuth is required
- Web search: auth-aware affordance, settings cog when user-provided and an
  info icon when system-defined
- Remove orphaned com_ui_unavailable/com_ui_initializing keys and the dead
  Tools/MCPToolItem component

* refactor: streamline MCP OAuth dialog

- Remove the Cancel button (the flow auto-closes on connect / times out)
- Show the URL in a read-only single-line scrollable input (cursor moves
  through it, not fully visible) with the shared CopyButton's smooth
  Copy/Check icon swap, matching the OAuth callback-URL field
- Put the primary Continue with OAuth action (icon trailing) and an
  icon-only QR toggle together in a row at the bottom, below the URL
- The QR reveals between the description and the URL with a smooth height
  animation (grid-rows 0fr to 1fr, matching MCPToolItem's reveal)

* feat: smoothly collapse MCP connect button once connected

* feat: cross-fade MCP tools between loading, list, and empty states

* feat: show MCP server icon in OAuth dialog title

* fix: vertically center OAuth dialog title against the MCP icon

* feat: smoothly animate auth field changes in the MCP server dialog

* feat: match Code Interpreter file upload to the File Search dropzone

Swap Code Interpreter's thin btn-neutral bar for the same dashed dropzone
(DropzoneContent + dropzoneClassName) File Search already uses, so the two
capabilities' upload UIs are consistent.

* feat: show a saving spinner and allow cancelling credential edits

Drive the tool credential Save button from the real mutation state so it
shows a spinner while the request is in flight, and add a Cancel button
when re-editing already-saved credentials so the edit can be dismissed.

* feat: make the skills create button a compact icon button

* fix: restore MCP attach semantics and confirmations in the tools marketplace

Connecting an MCP server from the item dialog now enables all of its tools
once the connection settles, deselect-all keeps the server attached via its
placeholder token instead of detaching it, adding a server writes the token
so a zero-tool attachment survives a save, and removing a server from the
tools list asks for confirmation again. Consume-only servers are excluded
from the catalog, matching the old select dialog.

Also share the catalog/selection pipeline between ToolsSection and the
marketplace through useAgentItems, hoist NEW_ACTION_ID next to ActionItem,
drop unused status/view union members and stale TranslationKeys casts,
document the phase-2 Favorites/Made-by-you views, fix the needs-setup dot
semantics and card focus suppression, remove the redundant close button in
CreateSkillDialog, move useInputModality into @librechat/client so external
consumers can mount it, and delete dead files and orphaned translation keys.

* fix: scope tooltip elevation to dialogs and restore dialog close button size

Tooltips go back to z-150 globally; inside a dialog they now borrow the
depth-aware popover z-index so they still clear nested dialogs (the Tool
Library item dialog) without outranking freshly opened modals everywhere
else. The default dialog close icon returns to its original size, and the
lc-field pointer-focus suppression ships with the package next to Input and
Textarea so external consumers get the whole mechanism from @librechat/client.

* feat: add favorites for marketplace tools, MCP servers, and skills

Reintroduce the favorite star from the old skill picker, generalized to
every marketplace item kind except per-agent actions. Cards in the Tool
Library and Skills dialogs get a hover-revealed star (always visible once
favorited), and the existing Favorites views in both dialogs now filter to
starred items.

Favorites persist in a dedicated ToolFavorite collection, one document per
(user, itemType, itemId) with a unique compound index, exposed through
atomic per-item PUT/DELETE endpoints under /api/user/settings/favorites/
tools. Per-item writes are idempotent and race-free across tabs/devices
(the unique index backstops concurrent toggles), reads are a single
index-backed query capped at 100 favorites per user, and the client keeps
React Query as the source of truth with optimistic updates. Handlers live
in @librechat/api with a thin route wrapper; methods follow the
data-schemas factory pattern with tenant isolation.

The favorites filter now matches on compound kind:id keys instead of bare
ids, closing a cross-kind collision where a tool and a skill sharing an id
would both match. The skill-favorites data-service stubs and the reserved
TUserFavorite.skillId field are replaced by the new tool-favorites service.

* feat: anchor the favorite star at the card's right edge

Swap the ToolCard action-bar order so the star sits rightmost with the
configure/info icon to its left. Every card can be favorited but only some
are configurable, so anchoring the star keeps it in a consistent position
across the grid.

* chore: remove translation keys orphaned by the tool library redesign

* fix: gate marketplace creation entries and resolve off-page selected skills

The Create New menu exposed MCP server creation to users without the
MCP_SERVERS create permission and action creation on deployments with the
actions capability disabled; both entries are now gated like their
pre-redesign counterparts, and the button hides when neither applies.

Selected skills missing from the first catalog page (limit 100) were
dropped from the Skills section entirely, leaving them impossible to
inspect or remove. useResolvedSkills restores the per-id lookup: off-page
skills are fetched individually and confirmed misses (deleted or no longer
shared) stay visible under an Unavailable skill placeholder so the stale
allowlist entry remains removable.

* fix: refetch favorites when toggled before the list loads, lint fixes

An optimistic favorite written over an unpopulated cache seeded the list
with only the toggled item, and cancelQueries killed the initial fetch
that would have corrected it, hiding existing favorites until reload. The
optimistic write now only applies over known data; otherwise onSettled
invalidates so the authoritative list is refetched.

Also unnest the version date-label ternary and drop an unused form watch
flagged by CI.

* fix: sync skills_enabled with selection edits and hydrate agent file entries

skills_enabled is the master opt-in for the skill allowlist, and an empty
allowlist with the flag on means the full accessible catalog. Selection
edits now sync the flag on empty/non-empty transitions via a shared
skillsEnabledTransition helper: picking the first skill enables it so the
choice takes effect on save, and removing the last one disables it so the
agent doesn't silently escalate to every skill. Mid-selection edits leave
the flag alone, preserving the Advanced kill switch's
disable-without-clearing behavior.

Agents loaded from the API carry only tool_resources.*.file_ids; the
client-only context/knowledge/code file entry arrays were read directly,
so existing attachments rendered as empty and could not be removed. A new
useAgentFileEntries hook restores the legacy derivation (agent files query
merged into the file map via processAgentOption) and now feeds AgentConfig,
the item dialog, and the selected-items pipeline.

* fix: hide plugin tools from the marketplace when the tools capability is off

buildCatalog gated built-ins, MCP, and skills on their capabilities and
permissions but pushed regular plugin tools unconditionally, so deployments
that removed the tools capability still offered attachable tool cards in
the marketplace. The loop now requires AgentCapabilities.tools, matching
the old Add Tools gate.

* fix: strip legacy MCP tokens on removal, guard action creation, model button spacing

MCP selection accepts every historical token format (server placeholder,
raw server name, mcp_-prefixed, and per-tool ids in prefix/suffix shapes)
but removal only filtered the new placeholder plus the server's current
tool ids, so a legacy token left the server permanently selected and its
tools still expanded after save. Selection and removal now share a
matchesMcpServer predicate.

Creating an action from the marketplace on an unsaved agent opened an
editor whose save was guaranteed to fail; it now surfaces the existing
save-the-agent-first error, matching the action-removal guard.

The model picker button keeps its tight px-1 with a provider icon but gets
px-3 in the empty Select-a-model state so the placeholder is not flush
against the border.

* fix: strip legacy prefix MCP tokens in useRemoveMCPTool

The hook only filtered the raw server name and suffix-delimiter tokens,
so confirming removal in the selected-tools section left persisted
prefix-format tokens (mcp_<server>, mcp_<server>_<tool>) in the form and
the row reappeared as selected. It now shares the matchesMcpServer
predicate with the selection logic so removal can never lag selection.

* fix: exact MCP token matching and keep errored skill lookups removable

The mcp_<server>_ prefix clause in matchesMcpServer was invented by the
redesign, not a persisted format (mcp_prefix is only ever used as the
exact mcp_<serverName> pluginKey), and it claimed longer server names
sharing a prefix: with servers github and github_extra, removing github
also stripped github_extra's tokens. The predicate now only matches exact
or delimiter-bounded shapes.

An off-page selected skill whose per-id lookup failed with a transient
error (retry disabled) vanished from the selected list until remount. Any
settled lookup failure now keeps the placeholder entry so the allowlist id
stays visible and removable; only in-flight lookups are briefly hidden.

* fix: route file-backed built-in removal to the file manager

Code Interpreter and File Search stay selected while they hold code_files
or knowledge_files, so removing them by flipping the capability flag left
the row visible and unremovable. Their removal now opens the config dialog
where the files are managed, mirroring the file-only context built-in;
with no files attached the flag still toggles off for a clean removal.

* fix: preserve negative values in numeric parameter inputs

sanitizeIntegerInput stripped every non-digit, so typing -1 in a numeric
parameter field became 1. That broke Google thinkingBudget, where -1 is
the dynamic/auto-thinking sentinel (range min is -1): users could no
longer select auto and risked sending a one-token budget. The sanitizer
now takes an opt-in allowNegative flag that keeps a single leading minus,
and DynamicInput passes it when the field's range permits negatives.
Thousands-separator cleanup is unchanged for all other fields.

* fix: keep in-progress negative numeric input and localize the actions heading

Typing a leading minus in a negative-capable numeric parameter (Google
thinkingBudget) sanitized to a lone '-', which was then coerced by
Number('-') to NaN, so the sign could not be typed before the digits. The
lone '-' is now stored as a string until a digit resolves it to a number,
matching how the empty-string case is already handled.

The agent builder actions panel heading hard-coded 'Add'/'Edit actions';
it now uses com_assistants_add_actions and a restored
com_assistants_edit_actions key so non-English locales translate it.

* chore: fix import order drift flagged by CI

* fix: treat pending web-search auth verification as needs_setup

While useVerifyAgentToolAuth is still loading, data is undefined so
web_search was not marked needs_setup, and the marketplace card takes the
direct-enable path only when status is not needs_setup. On a slow
connection a click before the response arrived enabled web_search without
collecting the required user-provided key. The auth map now flags
web_search needs_setup while the query is loading, routing the click to
the config dialog; once verification resolves, a system-defined deployment
or a satisfied key clears the flag for a direct toggle.

* test: update agent builder e2e selectors

🧹 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: Add showInMenu Option to Model Specs (#14034)
Add an optional `showInMenu` flag to model specs. When set to false, the
spec is dropped from the model selector menu and from the client startup
config (GET /api/config), but remains resolvable server-side by name — a
request that sends `spec: "<name>"` still works, since server-side
resolution uses the full, unfiltered list.

Unlike `showIconInMenu` (which only hides the icon), this hides the whole
entry. The flag is optional and defaults to listed, so existing specs are
unaffected.

Adds an `excludeHiddenModelSpecs()` helper (applied before
`sanitizeModelSpecs`) plus unit tests.

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

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

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

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

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

* fix(hitl): decouple ApprovalProvider from chat context

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

* fix(hitl): address Codex review — backend

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

* fix(hitl): address Codex review — frontend

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

* fix(hitl): address Codex re-review

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

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

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

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

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

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

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

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

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

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

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

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

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

Five findings verified against the code before fixing:

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

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

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

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

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

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

Four findings verified against the code before fixing:

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

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

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

Four findings verified against the code before fixing:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

🪙 fix: Count Quote Tokens on Message Edit (#13958)
The message-edit route recomputed a user message's tokenCount from the edited
`text` alone, ignoring its persisted `quotes`. But the send path re-prepends
those quotes into the prompt on every turn (mergeQuotedText), so after editing a
quoted message the stored tokenCount under-reported by the whole quote block,
skewing the context gauge and any other tokenCount consumer.

The full-recount path now fetches the message's quotes and counts the merged
text+quotes via a new `mergeQuotedTextForCount` helper in packages/api (mirrors
the send path), so the stored count stays authoritative. The incremental
content-part path is left as-is: it deltas only the edited part and preserves the
rest of the count (incl. the quote contribution), and applies to content-array
messages rather than text+quotes user turns.

♻️ refactor: Compute Context Gauge Client-Side, Drop Projection Endpoint (#13953)
* ♻️ refactor: Compute Context Gauge Client-Side, Drop Projection Endpoint

The /api/endpoints/context-projection endpoint re-fetched a conversation's
messages from Mongo and re-tokenized them to project the context gauge for
snapshot-less branches. The browser already holds those messages and their
per-message tokenCounts, so this duplicated work on the request path (an
unbounded read + server-side BPE tokenization until it was later capped).

Move the snapshot-less estimate fully client-side, from the in-memory index:

- sumBranch accumulates an uncalibrated char/4 estimate (estTokens) for
  count-less messages (imports / pre-feature) under the same summary cutoff
- useTokenUsage folds estTokens (calibrated via the existing calibrationFamily
  ratio) into the existing fallback; known per-message counts render unchanged
- delete the endpoint, controller, rate limiter, route, the getMessageTextStats
  data-schemas method, and the data-provider surface (endpoint/key/type/service/query)

No DB read, no server tokenization, no rate-limit knobs; the gauge recomputes
reactively from the index. Net -793 lines.

* 🩹 fix: Count quotes and object-form content in client context estimate

Address Codex review on the client-side context estimate:

- messageChars now reads object-form content text (part.text.value), not
  only string text/think, so imported / pre-feature messages whose body
  lives in content parts are no longer estimated as zero.
- Count-less user messages include their merged quote excerpts in the
  estimate, mirroring what the send path prepends into the prompt.

* 🩹 fix: Cap over-window estimate and surface estimated tokens in breakdown

Address remaining Codex review on the client-side context estimate:

- Clamp the snapshot-less estimate's displayed usedTokens to maxTokens. The
  send path prunes an over-window branch before calling the model, so the
  gauge never actually exceeds the window; this avoids impossible values
  (e.g. 50k / 8k) without re-introducing client-side pruning.
- Surface the calibrated count-less estimate as its own "Estimated" row in
  the breakdown popover, so a branch of only count-less imported / pre-feature
  messages is no longer shown as Input 0 / Output 0 under a non-zero header.

* 🩹 fix: Refine client context estimate per Codex re-review

- Drop calibration from the snapshot-less estimate. The removed projection
  never actually calibrated (the client never sent a ratio), and a ratio
  inflated by provider-injected context over-estimates visible imported text.
- Exclude reasoning (think) / error parts from the estimate; the send path
  strips them, so they are not part of the next call's context.
- Fold quote text into the estimate even when a tokenCount is present, since
  the edit route recounts tokenCount from text only and drops the merged quote.

* 🩹 fix: Recount quoted user turns instead of topping up the stored count

The previous round added quote chars on top of a quoted message's stored
tokenCount, which double-counts the common (unedited) case where the count
already includes the merged quote prompt. Match the removed projection
instead: for quoted user turns, ignore the stored count and estimate the
full merged text. This both avoids the double-count and still corrects the
stale text-only count an edit leaves behind.

* 🩹 fix: Trust stored counts for quoted turns; count tool-call parts

- Quoted user turns: revert to trusting a present tokenCount. The send path's
  stored count already includes the merged quote (and any calibration), and
  the client's char/4 path is coarser, so recounting regressed normal turns.
  Only count-less messages estimate quotes from text.
- Count tool-call name/args/output for count-less assistant messages; the
  formatter sends them back as context, so omitting them under-reported
  imported branches with tool history.

* 🩹 fix: Exclude in-flight tail from estimate to avoid resume double-count

On resume the live path seeds liveTokens from the partial response and also
writes that content into the messages cache, where the count-less response
is estimated into estTokens too — double-counting the in-flight output on the
snapshot-less estimate path. sumBranch now exposes the tail message's own
estimate (tailEstTokens); the estimate path drops it while a stream is live,
so the in-flight response is counted once (via liveTokens). The breakdown's
Estimated row uses the same in-flight-adjusted value.

* 🩹 fix: Recount quoted user turns in context estimate (match send path)

A quoted user turn's stored tokenCount is unreliable for the gauge: a
text-only Save edit recomputes it from text alone, and the send path
(needsCanonicalTokenCount in agents/client.js) recounts the quote-merged
prompt every turn regardless of the stored value. Mirror that on the client
— estimate quoted turns from the merged text+quotes and ignore the stored
count — so snapshot-less branches don't under-report by the quote block.
Reverts the earlier "trust the count" assumption, which the server disproves.

* 🧹 chore: Route useResumableSSE diagnostics through the frontend logger

Convert the [ResumableSSE]/[Debug] console.log and console.error diagnostics
to the gated frontend `logger` (client/src/utils/logger), splitting the tag
from the message so object arguments are passed through as real args (logged
expandably, not stringified) and the logs stay tag-filterable and off the
production console unless explicitly enabled. All log statements preserved;
nothing removed.

* 🩹 fix: Prefer content over text when estimating count-less messages

A stopped agent response is saved with both a `text` field and a structured
`content` array, and the send path formats from content. messageChars
early-returned on `text`, dropping the content array (and the tool-call tokens
it carries) from the snapshot-less estimate — also making the tool_call
handling dead for such messages. Prefer content when present, fall back to text.

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

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

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

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

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

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

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

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

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

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

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

* 🔑 fix: Carry tool_call_id On ToolReviewConfig (HITL)

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

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

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

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

* fix: Address HITL review findings

* fix: Refresh paused HITL Redis state

* test: Stabilize HITL abort fallback specs

* 🎨 style: Sort imports to satisfy dev lint gate (HITL)

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

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

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

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

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

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

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

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

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

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

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

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

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

Three P2 findings on 780833d908, all valid:

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

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

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

Five P2 findings on 4324a4e776, all valid:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

🔄 feat: 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: Audit Log Backend for SystemGrant Assign and Revoke Events (#13087)
* 🛡️ feat: Audit log backend for SystemGrants changes

Add an AuditLog Mongoose collection that records every grant assign/revoke as an append-only entry capturing the actor, target principal, capability, timestamp, and tenant scope. Wire the entry-write into the existing admin assignGrant and revokeGrant handlers so the admin panel's audit-log tab populates as grants happen.

The data-schemas package gains the IAuditLog type, a Mongoose schema with tenant + target compound indexes for keyset pagination, a model factory wired through createModels, and an AuditLog methods factory exposing recordAuditEntry, listAuditLogPage (cursor-paginated, faceted, search-aware), findAuditLogEntry, and streamAuditLogEntries.

The packages/api admin layer adds createAdminAuditLogHandlers with three handlers backing the routes the admin panel already consumes: GET /api/admin/audit-log returns paginated entries, GET /api/admin/audit-log/:id returns a single entry for the permalink drawer, and GET /api/admin/audit-log/export.csv streams CSV with formula-injection defang plus UTF-8 BOM.

The Express layer mounts the new router at /api/admin/audit-log behind requireJwtAuth and the ACCESS_ADMIN capability, matching the existing admin route pattern. The audit emission failure is logged via logger.error but never rolls back the grant.

* 🧹 chore: Audit log backend cleanup — offset pagination, name-based filters, type tightening

Switch listAuditLogPage from cursor-based to offset-based pagination with skip().limit() + parallel countDocuments, returning { entries, total } instead of { entries, nextCursor }; the cursor encode and decode helpers are no longer needed and have been removed.

Interpret the actorId and targetPrincipalId filter parameters as case-insensitive partial regex against the denormalized actorName and targetName fields rather than exact-match against the underlying ObjectId. Admin panel users naturally filter by human name, not by Mongo identifier.

Replace the broad Record<string, unknown> casts on req.query with a typed AuditLogQuery shape, drop two unused exported types and the now-unused mongoose Types import, and fix the streamAuditLogEntries Omit literal to match the interface and the offset-based design.

* 🛠️ fix: Address audit log review feedback (CI typecheck, ISO offsets, no-op revoke, deps surface, schema, backpressure, tests)

Resolve the duplicate AuditAction export that broke the data-schemas TypeScript check by importing the canonical declaration from types/admin instead of re-declaring it in types/auditLog.

Accept timezone-offset ISO 8601 timestamps such as 2026-05-01T09:30:00+02:00 in the from and to filter params and reject local-time strings without a zone so every request resolves to an unambiguous instant.

Skip the audit emission on no-op revokes: revokeCapability now returns deletedCount so the admin handler can omit the grant_removed entry when the target grant did not exist, keeping the audit trail factually accurate. Mocks in the existing grants.spec.ts updated to the new return shape.

Drop the required recordAuditEntry from AdminAuditLogDeps since the audit-log handler factory never consumes it; the grants handler factory keeps its optional dep for the write path.

Tighten the tenantId validator on the audit log schema to require a non-empty trimmed string, and rewrite the listing-index comment to describe deterministic offset sort instead of keyset pagination.

Stream the CSV export with explicit backpressure (await drain when res.write returns false) and abort on client disconnect so a cancelled download no longer pins a Mongo cursor or buffers unbounded data in memory.

Add packages/data-schemas/src/methods/auditLog.spec.ts covering tenant and platform scoping, single and multi action filtering, partial-name filtering for actor and capability, the createdAt window, offset pagination with total, ObjectId and date stringification on the wire, regex-metacharacter escape, and streaming completeness.

* 🛠️ fix: Address P1 audit-log review findings (cursor cancel, drain race, filter naming, type dedupe, tenant scope, log enrichment)

The CSV stream handler kept draining Mongo batches after the client
disconnected because the `for await` loop only honored its abort flag
inside `onEntry`. Thread an `isCancelled` callback into
`streamAuditLogEntries` so the methods layer closes the cursor as soon
as the handler sees `close`/`aborted`; a `finally` block guarantees
release on throw. The drain promise in `writeChunk` now races against
the response's `close` event so a destroyed socket cannot strand the
handler on a `drain` that will never fire.

The HTTP filter keys `actorId` and `targetPrincipalId` always did
case-insensitive substring matches on the denormalized `actorName` /
`targetName` columns, never on ObjectIds — a client passing a real id
silently got zero rows. Renamed the wire-level keys to `actorQuery` /
`targetQuery` (matching what the matcher actually does) and kept the
old names as deprecated aliases for one release so the sibling
admin-panel PR can migrate without breaking; each legacy use logs a
deprecation warning. Renamed the corresponding fields in
`AuditLogFilters` too.

`AdminAuditLogEntryWire` duplicated `AdminAuditLogEntry` from
`types/admin.ts` field-for-field, violating the no-duplicate-types
rule. Deleted the duplicate, hoisted `AuditLogPage`,
`RecordAuditEntryInput`, and `AuditLogFilters` from
`methods/auditLog.ts` into `types/auditLog.ts`, and updated the
handler, method factory, and re-exports accordingly.

`tenantFilter` treated `''` as a valid tenant scope, producing a
`{ tenantId: '' }` query that silently returned nothing while the
schema validator rejected `''` on writes. Switched to a strict
`typeof tenantId === 'string' && tenantId.trim().length > 0` check so
reads agree with writes, with new spec coverage for empty and
whitespace-only inputs.

Audit-write failures now log the full forensic payload (action,
capability, tenantId, actorId, target metadata) inside a single meta
object so winston's standard signature surfaces it correctly; a comment
on the catch block explains why the failure mode stays silent (it must
never block a privileged operation).

Stronger filter parsing: invalid `action` values and unknown
`targetPrincipalType` now return 400 instead of silently dropping.
Extracted `MAX_LIMIT` to a constant. Replaced the
`Record<string, Date>` cast in `buildFilter` with a typed local.
Switched the stream cursor to `lean<IAuditLog[]>()` and removed the
`as IAuditLog` cast inside the loop.

* ✅ test: Cover admin audit-log handler with unit tests for auth, validation, tenant isolation, CSV output, and abort

The sibling admin handlers (grants, groups, roles, users) all have
handler specs; this one was missing. The new suite covers 401 on a
missing `req.user`, 400 on malformed ISO `from` / `to`, 400 on
limit > 500, 400 on negative offset, 400 on an unknown action or
`targetPrincipalType`, 400 on a non-ObjectId `:id`, 404 when the
methods layer returns null, that the caller's `tenantId` (not a
forged query-string `tenantId`) is the one passed to the methods
layer, that `actorQuery` / `targetQuery` round-trip, that the
deprecated `actorId` / `targetPrincipalId` aliases still map through,
that the CSV stream emits the BOM as the first chunk with CRLF line
endings and the expected header labels, that quotes, commas, and
newlines are properly escaped, that the formula-injection prefixes
(`=` `+` `-` `@` tab CR) are defanged, that an `isCancelled` callback
reaches the methods layer and flips to true on client `close`, and
that `res.end` is skipped when the client disconnected mid-stream.

* 🛡️ feat: Enforce append-only AuditLog at the schema level

Every field is now marked `immutable: true`, and pre-hooks on the
schema reject `updateOne`, `updateMany`, `findOneAndUpdate`,
`findOneAndReplace`, `replaceOne`, `deleteOne`, `deleteMany`,
`findOneAndDelete`, plus any `save()` against an existing document.
`timestamps` is reduced to `{ createdAt: true, updatedAt: false }`
since a mutable timestamp would imply mutation is allowed, and
`updatedAt` is dropped from `AuditLog` / `IAuditLog`. The methods
spec resets state between tests via the raw driver (`AuditLog.collection.deleteMany`),
which bypasses the pre-hooks; new specs assert that the model-level
update / delete / re-save paths reject with the append-only error and
that `updatedAt` is not stamped on new documents.

* ♻️ refactor: Share MAX_AUDIT_LOG_LIMIT between methods and handler

Renamed the methods-layer constant from the generic `MAX_LIMIT` to
`MAX_AUDIT_LOG_LIMIT`, exported it through `@librechat/data-schemas`,
and consumed it from the handler instead of duplicating `500` there.
Now the limit is single-sourced; bumping it once updates both the
clamp inside `listAuditLogPage` and the 400-error boundary the
handler returns to clients.

* 🛡️ feat: Gate audit-log routes on a dedicated `READ_AUDIT_LOG` capability

The audit-log routes were gated on `ACCESS_ADMIN`, which conflates "can log
into the admin panel" with "can see who granted what to whom." Anyone with
`ACCESS_ADMIN + READ_CONFIGS` (a config reviewer with no people-management
authority) could read the grant history of every user, group, and role —
information they have no need to know.

`READ_AUDIT_LOG` ('read:audit_log') is now an explicit, separately grantable
read capability with no MANAGE counterpart, matching the append-only nature
of the collection. `seedSystemGrants` iterates `Object.values(SystemCapabilities)`
so existing ADMIN-role seeds pick it up automatically on next startup.

This also makes an "auditor" persona possible: hold `ACCESS_ADMIN + READ_AUDIT_LOG`
without any MANAGE_* grants and you can review history without modifying anything.

* ♻️ refactor: Share AUDIT_ACTIONS, tighten audit dep types, document route order

Exports a runtime AUDIT_ACTIONS array from packages/data-schemas alongside the
AuditAction type so the Mongoose schema enum and the HTTP handler's whitelist
consume one source of truth instead of duplicating the literal pair.

Switches the grants handler's recordAuditEntry dep typing from a duplicated
inline object literal returning Promise<unknown> to the published
RecordAuditEntryInput type returning Promise<void>, and tightens the local
emitAudit args to AuditAction. Replaces the local ParsedFilters interface in
the audit-log handler with Omit<AuditLogFilters, 'offset' | 'limit'> to drop
the duplicate definition.

Drops the optional marker on AuditLog.createdAt. Mongoose always sets it at
insert time, so callers treating it as nullable were guarding against a state
the schema does not produce.

Adds a comment on api/server/routes/admin/audit.js noting that /export.csv
must precede /:id so a future contributor does not accidentally reorder them
into a 404 trap.

* 🛡️ feat: Resolve audit names without extra DB round-trips

For the actor name, JWT-authenticated `req.user` already carries `name`,
`username`, and `email`. `resolveUser` now derives the actor display name
from `req.user` directly and threads it through the caller context, so
every grant assign and revoke no longer triggers a separate `getUserById`
lookup.

For the target name, replaces the previous always-store-the-principalId
behavior (which buried opaque ObjectId strings in immutable audit rows
for USER and GROUP targets) with a `resolveTargetName` dep. ROLE
principals continue to use `principalId` directly because the SystemGrant
model stores role names there. USER and GROUP principals route through
the new dep, which in `api/server/routes/admin/grants.js` calls
`db.getUserById` or `db.findGroupById` respectively and falls back to
the principalId on miss or error so the audit row stays intelligible.

Drops the misleading "display name lookup happens in a later iteration"
comment.

* ✅ test: Cover audit emission, scope emitAudit to today's ROLE-only surface

Fixes a misleading test that claimed to verify "idempotent even if the grant
does not exist" while mocking deletedCount: 1 (the grant DID exist). Replaces
it with the actual no-op scenario (deletedCount: 0) and adds an assertion
that recordAuditEntry is NOT called, since the whole point of the
deletedCount > 0 gate is to avoid fictitious revocation rows.

Adds a dedicated audit emission describe block covering: grant_assigned
emission with the actor name resolved from req.user, grant_removed
emission when deletedCount is positive, and the no-emission fallback when
recordAuditEntry is not configured. The actor-name assertions exercise the
name / username / email fallback chain in resolveUser.

The previous commit also added a `resolveTargetName` dep and an
emitAudit branch for USER/GROUP targets. The grants surface is ROLE-only
today (MANAGE_CAPABILITY_BY_TYPE has only PrincipalType.ROLE), so that
code path is unreachable from the handler. Removed the dep and the
branch; the audit row uses principalId as the target name, which is the
human-readable role name for ROLE principals. A comment in emitAudit
flags where to plumb resolveTargetName back in once USER and GROUP
grants are enabled.

* 🛠️ fix: Inclusive `to` date filter and reject inverted ranges

A `?to=2025-01-15` filter previously stopped at midnight UTC of that
day, silently excluding everything that happened on January 15. The
`parseIsoDate` helper now widens a bare `YYYY-MM-DD` to 23:59:59.999Z
when called with the `end` boundary. Full ISO timestamps are honored
exactly, so callers that want minute-precision can still get it.

Also rejects inverted ranges (`from` later than `to`) with a 400 so
operators see a clear error instead of a silent empty result.

* 🛡️ feat: Cap audit-log CSV exports at 100k rows; cover stream error path

Introduces MAX_AUDIT_EXPORT_ROWS (100k) and threads a `maxRows` option
through streamAuditLogEntries. The handler now passes the cap into the
stream so a careless admin script or a hostile auditor cannot pin a
Node worker and a Mongo cursor by exporting unbounded result sets.
Beyond 100k rows, callers should slice exports by from / to date.

Adds a methods-layer spec for the cap behavior, a handler-layer spec
that asserts the option is plumbed through, and a handler-layer spec
that exercises the streamAuditLogEntries-throws-after-headers-sent path
(catch block falls through to res.end instead of attempting JSON).

Documents on buildFilter that case-insensitive substring regex filters
(actorName, targetName, capability, search) cannot use a B-tree index
and degrade to a tenant-scoped partition scan, so deployments with
hundreds of thousands of audit rows per tenant should constrain those
queries with a date window.

* 🧹 chore: Spell CSV_BOM as  and drop a gratuitous optional chain

`revokeCapability` is typed `Promise<{ deletedCount: number }>` so the
`?.` on `revokeResult?.deletedCount` only obscured that the value cannot
be nullish.

`CSV_BOM` was a literal U+FEFF character invisible in most editors. Now
spelled as the Unicode escape so readers can see the constant; the test
that asserts on the first emitted chunk uses the same escape.

* 🔧 chore: Allowlist AuditLog in the tenant-isolation coverage guard

The AuditLog collection carries a tenantId field but scopes tenancy manually
inside listAuditLogPage / streamAuditLogEntries / recordAuditEntry using the
same $exists: false convention as SystemGrant. The tenant-isolation plugin
coverage spec now allows that and asserts it stays accurate.

* 🛠️ fix: Normalize blank tenantId before persisting audit entries

The `recordAuditEntry` write path was treating any non-null tenantId as a
real string, so empty or whitespace-only values reached the schema validator,
failed the non-empty-string check, and silently dropped the audit row. The
read-side `tenantFilter` already treats those values as platform-level scope,
so the write path now mirrors it: blank or whitespace-only tenantId becomes
an omitted field, which matches `{ tenantId: { $exists: false } }` queries
and clears validation. Added a regression test that records two entries with
blank and whitespace tenantId and asserts both persist with the tenantId
field absent.

* 🎨 style: collapse expect.objectContaining onto one line to satisfy prettier

* 🔒 fix: block document-level deleteOne/updateOne on AuditLog

Mongoose registers deleteOne and updateOne pre-hooks as query middleware
by default. The query-level append-only block on AuditLog therefore did
not cover Document.prototype.deleteOne() or Document.prototype.updateOne(),
leaving a path where a caller that had already loaded an audit row via
findOne could call .deleteOne() or .updateOne() on the instance and bypass
the schema contract.

Explicit { document: true, query: false } registrations close the holes,
and the spec now covers both code paths against a real in-memory Mongo.

* 🔒 fix: require ACCESS_ADMIN on audit-log routes

Every other admin router (config, grants, users, roles, groups, auth)
enforces requireJwtAuth followed by requireCapability(ACCESS_ADMIN) before
any feature-specific capability check. The audit-log router only required
READ_AUDIT_LOG, which is independent of ACCESS_ADMIN in CapabilityImplications,
so a role delegated only READ_AUDIT_LOG without ACCESS_ADMIN could read or
CSV-export the audit trail and bypass the admin boundary.

Aligned the middleware chain with the rest of the admin surface so
ACCESS_ADMIN gates entry and READ_AUDIT_LOG gates the feature within it.

* 🎨 chore: re-sort imports after dev rebase

Post-rebase sort-imports against the merge target — six audit-log files
landed with stale import ordering relative to the current scripts/sort-imports.mts
rules on dev. CI's import-order job flagged the drift; running the script
locally rewrites them in place. No semantic changes.

* 🔧 fix: explicit type annotations on audit-log model + schema exports

Dev migrated packages/data-schemas builds from rollup to tsdown with
--isolatedDeclarations enabled, which requires every exported function to
declare its return type and every exported variable to declare its type.
Two of our audit-log exports got swept up:

  TS9007 models/auditLog.ts:12  createAuditLogModel return type
  TS9010 schema/auditLog.ts:12  auditLogSchema variable type

Added Model<t.IAuditLog> on the factory and Schema<IAuditLog> on the
schema variable, matching the sibling SystemGrant convention. No runtime
behavior change.

* 🔧 fix: align revokeCapability type annotation with implementation

The rebase auto-merge of systemGrant.ts kept dev's outer type annotation
(`revokeCapability: ... => Promise<void>`) but our implementation returns
`Promise<{ deletedCount: number }>` (added during the bot-review loop to
let the audit emitter distinguish a real revoke from a no-op against a
nonexistent grant). The mismatch surfaced as TS2719 on the methods record
return at line 520. Updated the type annotation to match the impl.

The caller at packages/api/src/admin/grants.ts:444 reads
`revokeResult.deletedCount` to gate the audit emit, so the wider return
type is what the rest of the code already assumes.

* 🔧 fix: explicit factory return type on createAdminAuditLogHandlers

Same tsdown --isolatedDeclarations migration that hit packages/data-schemas
also applies to packages/api; the audit-log handler factory's inferred
return type tripped TS9013 against the new build pipeline. Annotated the
factory with explicit handler signatures matching the sibling
createAdminGrantsHandlers convention. Used Promise<Response | void> for
the export handler because its final res.end() path returns undefined,
unlike the other two handlers which always return a Response.

* 🛡️ feat: Generalize audit log into a tamper-evident, extensible event substrate

Reworks the SystemGrant-only audit log into a general-purpose, append-only
compliance substrate designed to absorb future event classes (agent runs,
tool/MCP calls, config + permission changes, approvals) without reshaping the
record. Nothing was shipped yet, so this replaces the grant-specific wire
shape rather than layering aliases.

Schema / record shape (packages/data-schemas):
- schemaVersion + two-level taxonomy: category + namespaced action
  (grant.assigned/grant.removed), first-class outcome and severity.
- Structured actor{type,id,name} supporting non-user actors (system, agent,
  service, schedule, webhook, api); generic target{type,id,name}; open
  metadata map; request context{requestId,ip,userAgent,sessionId}.

Tamper-evidence (hash chain):
- Per-tenant chain keyed by chainKey with seq/prevHash/hash. Appends link to
  the previous hash; a unique {chainKey,seq} index serializes concurrent
  writes (dup-key retry) so the chain can never fork. createdAt is explicit so
  it's covered by the hash.
- verifyAuditChain() walks a chain and detects modification, deletion, and
  forged links; exposed via GET /api/admin/audit-log/verify.

Other best-practice gaps from the review:
- Keyset (cursor) pagination over seq alongside offset; stable under
  concurrent appends. nextCursor in the page payload.
- Retention: purgeAuditLogEntries() privileged prefix-purge with a confirm
  latch, returns a checkpoint; verify tolerates a purged prefix.
- Fail-closed option (AUDIT_LOG_FAIL_CLOSED) so a failed audit write can fail
  the grant request instead of being swallowed; default stays fail-open.
- Grant handlers now capture request context and emit the new shape.

CSV export updated for the new columns (incl. seq/hash). data-schemas bumped
to 0.0.54 for the sibling admin-panel consumer. Tests rewritten: 28
methods-layer cases (chain genesis/linking, tamper detection, keyset, purge)
and the handler/grants specs updated for the new shape, fail-closed, and the
verify endpoint.

* 🛠️ fix: Address Codex review on the audit-log substrate

- F1 (fail-closed atomicity): assign/revoke now compensate (rollback grant /
  restore grant) when a fail-closed audit write fails, so a 5xx never leaves an
  unaudited mutation.
- F5: only emit grant.assigned for a real change — skip the audit when the role
  already holds the capability (idempotent re-assert).
- F7: verifyAuditChain no longer silently trusts a non-genesis start; a purged
  prefix must be authorized by a trusted checkpoint (purge now returns
  {throughSeq, prevHash}), else verification fails as tampering.
- F4: block Model.bulkWrite on AuditLog (would bypass the append-only middleware).
- F3: CSV export appends an explicit TRUNCATED marker + logs when the row cap is hit.
- F6: reject out-of-range date-only filters (2025-02-31) instead of normalizing.
- F2: regenerate package-lock.json for the 0.0.54 data-schemas bump.

Tests: +1 methods (bulkWrite) +2 verify (deleted-prefix / checkpoint mismatch),
updated purge test for checkpoint flow; +4 api (re-assert skip, assign/revoke
fail-closed rollback, date reject, CSV truncation marker).

* 🛠️ fix: Address Codex round-2 on the audit-log substrate

- R2-1/R2-5 (P1/P2): base the grant.assigned audit decision on the atomic
  upsert result. grantCapability now returns { grant, created } via
  includeResultMetadata; the handler audits only when created. Removes the racy
  pre-read, which also mis-handled inherited platform grants vs a new
  tenant-scoped insert and concurrent double-assign.
- R2-2 (P2): namespace tenant chain keys (tenant:<id>) so a tenant whose id is
  literally the platform sentinel can't share the platform audit chain.
- R2-4 (P2): validate literal calendar tokens for full ISO timestamps too, so
  2025-02-31T00:00:00Z is rejected instead of normalizing to March 3.

Tests updated for the grantCapability { grant, created } contract (systemGrant +
grants specs) and the namespaced chain key (auditChainKey helper); +1 api date
case. data-schemas 141, api grants/audit 107 green.

R2-3 (deprecated actorId/targetPrincipalId aliases): not reinstating — the
surface is pre-release and its only consumer (admin-panel PR) migrates to the new
shape in lockstep, so there are no legacy clients to support.
R2-6 (role-deletion cascade emits no grant.removed): valid but a separate
workflow in roles.ts; tracked as a follow-up to keep this PR scoped.

* 🛠️ fix: Address Codex round-3 on the audit-log substrate

- R3-3 (P2): make a grant re-assert a true no-op — move grantedAt/grantedBy to
  $setOnInsert so an existing grant is never silently mutated when the audit is
  skipped (created:false now means nothing changed). grantedAt/grantedBy record
  the original grant.
- R3-2 (P2): report CSV export truncation exactly. streamAuditLogEntries returns
  { count, truncated }; truncated is true only when rows existed beyond the cap,
  so an exact-cap export is no longer falsely marked truncated.
- R3-5 (P2): block AuditLog.insertMany (another bulk path that skips the save
  hook and could inject forged seq/prevHash/hash and poison the chain).

Tests: +insertMany rejection, +exact-cap vs truncated stream cases, +exact-cap
export-not-truncated handler case. ds 142, api 108 green.

R3-1 (deprecated query aliases) and R3-4 (role-deletion cascade audit) are
re-flags of R2-3/R2-6 — holding the prior decisions (pre-release surface; separate
roles.ts workflow tracked as a follow-up), pending maintainer direction.

* 🛡️ feat: Audit grant removals from the role-deletion cascade

Closes the forensic gap Codex flagged (R2-6/R3-4): deleting a role removed its
SystemGrants with no audit entries. `deleteGrantsForPrincipal` now returns the
removed grants, and the role-deletion handler emits a `grant.removed` audit entry
per removed grant (actor = caller, target = role, metadata.capability, request
context), matching the explicit revoke endpoint. Fail-open — the role is already
deleted, so a failed audit is logged, not propagated; sequential to keep the
per-tenant hash chain ordered.

Extracted `buildAuditContext` to admin/context.ts (shared by grants + roles).
Tests: role-deletion emits one entry per grant / none when no grants; ds 110,
api admin 202 green.

* 🛠️ fix: Address Codex round-4 on the audit-log substrate

- R4-1 (P2): don't silently drop an audit row under heavy append contention.
  recordAuditEntry now retries duplicate-key seq collisions up to 12× with
  jittered backoff (was 5, no backoff), so realistic bursts of parallel admin
  writes resolve; the failClosed escape still applies on true exhaustion.
- R4-3 (P2): purge a contiguous seq prefix, not a date range. createdAt is
  app-generated, so under multi-instance clock skew a later seq can carry an
  earlier timestamp; a raw date delete could remove an interior row and break
  verification. purgeAuditLogEntries now resolves the date to the first retained
  seq and deletes only strictly-lower seqs, keeping the remaining chain contiguous.

Tests: +clock-skew purge case (no gap created). ds auditLog 33 green.

R4-2 (role-deletion grant audit) is a re-flag of R2-6/R3-4, already implemented
in 15472127d6 (roles.ts emitGrantRemovals + route wiring + tests); the finding's
cited line numbers predate that commit.

* 🛠️ fix: Address Codex round-5 on the audit-log substrate

- R5-1 (P2): scope each cascade grant.removed entry to the removed grant's own
  tenant, not the caller's. A platform admin deleting a role can remove
  tenant-scoped grants; those removals now land in the affected tenant's chain.
- R5-2 (P2): only return a purge checkpoint when rows were actually deleted. A
  no-op confirmed purge no longer mints a trust boundary that could legitimize a
  prefix it didn't authorize.
- R5-3 (P2): ensure the unique { chainKey, seq } index exists before appending
  (memoized createIndexes), so serialization doesn't depend on a background build
  — closes a silent chain-fork window under MONGO_AUTO_INDEX=false or at startup.

Tests: +per-grant-tenant cascade audit, +no-op-purge-no-checkpoint,
+index-built-before-append. ds auditLog 35, api roles 95 green.

🛂 refactor: Accept Targeted assign:configs for Config Scope-Lifecycle Endpoints (#13773)
* 🔓 fix: Accept Targeted assign:configs for Config Scope-Lifecycle Endpoints

Three admin-config endpoints currently require broad manage:configs: PUT /:principalType/:principalId for empty-overrides scope creation, DELETE /:principalType/:principalId for scope removal, and PATCH /:principalType/:principalId/active for the active toggle. The capability model already defines assign:configs:user|group|role for delegated administrators and validates that shape in isValidCapability, but no handler accepts it, so a delegate granted assign:configs:role via /api/admin/grants cannot manage scope lifecycle for the principal type they were explicitly delegated.

This aligns the server-side auth with the documented capability surface. Every destructive lateral path stays behind broad manage:configs: operations against the base config principal (__base__), non-empty PUT payloads that $set the full overrides field, and DELETE or toggle on a document whose existing overrides are non-empty (which would erase or neutralize sections the caller could not author). The new hasCapability dep on AdminConfigDeps is optional with a false default, so external consumers continue to get pre-PR behavior until they wire the resolver.

* 🛡️ fix: Block Assign-Only Scope-Lifecycle When Existing Doc Has Tombstones

The existing-overrides guard introduced in the prior commit only checked overrides, but configs also carry tombstones (suppressed inherited field paths) which are iterated during cascade resolution. An assign-only caller could delete, toggle, or empty-upsert a doc whose overrides is empty but whose tombstones is non-empty, which would erase or neutralize suppressions on fields they could not author. Extends the guard at all three call sites to treat a non-empty tombstones array as destructive state.

* 🚨 fix: Log TOCTOU Race When Assign-Only Lifecycle Op Hits Non-Empty Doc

The empty-state guard for assign-only callers performs a read-then-write across two DB roundtrips, so a concurrent broad-manage write can land between the guard and the destructive op. Adds post-write detection on the delete and toggle handlers: when the destructive op returns a doc whose state was non-empty at write time, emit logger.warn with the caller id, principal, and observed-state counts so ops can detect the race and restore from audit logs.

A fully atomic fix would require extending deleteConfig, toggleConfigActive, and upsertConfig in packages/data-schemas/src/methods/config.ts to support compare-and-swap filters, which is a wider design change than this PR's auth scope. Empty-payload upsert is not covered because $set replaces overrides, so the post-write doc no longer reflects pre-write state.

* 🔒 fix: Atomic Empty-State Filter for Assign-Only Scope-Lifecycle Writes

Replaces the read-then-check guard with an atomic Mongo filter on the destructive write itself. Adds an options.expectEmpty parameter to deleteConfig, toggleConfigActive, and upsertConfig in the shared data-schemas layer. When set, the filter requires both overrides and tombstones to be empty before the write matches. The TOCTOU race window is eliminated: a concurrent write cannot land between the empty-state check and the destructive op because they are now a single atomic operation.

For upsertConfig, the E11000 retry path returns null instead of falling back to a filterless update when expectEmpty is set, preserving the atomic property. Handlers fall back to findConfigByPrincipal only to disambiguate the null return between 404 (doc absent) and 403 (doc exists with non-empty state). The post-write logger.warn race detection added in the prior commit is removed as unreachable.

🔖 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.

* 🪙 feat: Context-usage projection — data-provider + client wiring

Consumer side of the SDK-aligned context projection (agents
`projectAgentContextUsage`). Adds the `/api/endpoints/context-projection`
data-provider plumbing (endpoint, service, query key, `TContextProjectionRequest`)
and a `useContextProjectionQuery` gated to fire only when no fresh snapshot
covers the viewed branch.

Wires `useTokenUsage` precedence to: live snapshot → fresh persisted snapshot
(window matches the resolved one) → server projection → per-message estimate.
A model/window switch marks the baked snapshot stale (its `maxContextTokens`
no longer matches) and falls to the projection — closing the gauge's
window-switch (G1) and snapshot-less-branch (G2) gaps. Snapshot and projection
share the render-relevant fields, so they render uniformly.

Backend endpoint + agents version bump land in follow-up commits. Includes the
design spec (CONTEXT_PROJECTION_SPEC.md).

* 🪙 feat: Context-projection backend endpoint

POST /api/endpoints/context-projection → resolveContextProjection (packages/api):
reconstructs the viewed branch (parent-chain walk from messageId), resolves the
agent config (instructions/provider/model/maxContextTokens), reuses LibreChat's
stored per-message tokenCounts as the index map (no re-tokenizing), and calls
the agents SDK projectAgentContextUsage — no model call. Thin controller injects
db.getMessages/db.getAgent; route mirrors /token-config.

First cut targets message-windowing accuracy; tool-schema tokens are deferred to
a follow-up that reuses the full initializeAgent path.

* 🩹 fix: Codex review on context projection (G1 guard, IDOR, recount, summary)

- Guard `currentActive` against a stale window: a model/window switch on the
  current branch left the live snapshot outranking the projection (G1 didn't
  fire). Now defers to the projection unless streaming or the window matches.
- Scope branch lookups to the authenticated user (`getMessages` filter +
  injected `userId`) — was loading any conversation by id (IDOR).
- Recount messages with no stored `tokenCount` via the tokenizer instead of
  charging 0, so snapshot-less/imported histories don't under-report.
- Fall back (null) for already-summarized branches rather than projecting from
  the full raw parent chain (the next call would send summary + tail); the
  client's summary-baseline-aware estimate handles them until a follow-up
  replays the summary boundary.

* 🩹 fix: Codex round 2 — drop agent load, summary marker, edit-invalidation

- Stop loading agent/model-spec config server-side (closes the agent-access
  IDOR and the spec-prompt special-casing). Provider/model/window now come from
  the client-resolved request (`limits.endpoint`/model — the agent's real
  provider, not the `agents` endpoint, so the tokenizer is right). Agent/spec/
  promptPrefix instructions are uniformly deferred to the full-fidelity follow-up.
- Detect summarized branches via the live path's `metadata.summaryUsedTokens`
  marker (was the wrong `summaryTokenCount` field) and fall back to the
  summary-aware estimate.
- Invalidate the projection query on in-place message edits via a branch
  content `revision` in the cache key (the tail id is unchanged on edit).

Deferred (valid, not a regression): same-window endpoint/model switch keeps a
window-matched snapshot — needs endpoint/model persisted on the snapshot, which
lands with the fidelity follow-up. Smoke-tested: fits / prunes / summarized→null
/ no-window→null.

* 🛡️ fix: make context projection strictly additive (no-regression)

Revert the G1 window-match guard on the live/branch snapshot. When no explicit
maxContextTokens is set (the common default), the SDK's snapshot window is
reserve-derived (~0.9·(modelContext − maxOutputTokens)) while useTokenLimits
resolves the raw model context — so `snapshot.maxContextTokens === resolvedMax`
is false for the SAME model, and the guard would wrongly drop a valid
current-branch snapshot to projection/estimate post-stream (a regression in the
default case, per initialize.ts:1240-1243).

The projection now activates ONLY for snapshot-less branches (G2): the
precedence is live snapshot → persisted branch snapshot → projection → estimate,
where the first two are byte-for-byte the prior behavior and the projection just
slots ahead of the estimate. Window/model-switch (G1) detection needs the
snapshot to carry its model/window and defers to the fidelity follow-up.

* 🩹 fix: surface projections as estimates, not authoritative snapshots

A first-cut projection carries the SDK's windowing but omits instruction/tool
overhead, so rendering it as `isEstimate: false` showed a confident under-count
for snapshot-less branches. Mark projection-sourced views `isEstimate: true` +
`snapshotActive: false` (and drop the snapshot field) so they present as a
better estimate than sumBranch — improved used/window number, estimate framing,
no misleading granular breakdown with ~0 tools. Real snapshots stay
authoritative. (Codex round 3, projection.ts:139.)

never a snapshot to seed from in this branch — so just remove it.

🥽 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.

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

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

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

* 🧹 chore: Remove orphaned com_ui_session_cost i18n key

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* 🪙 fix: Keep Tagged Usage Buckets Out of the Live Context Estimate

* 🩹 fix: Scoped Token-Config Fallback and Sequential Visibility for Usage Events

* 🩹 fix: Address Usage Review Findings — Cost Timing, Scoped Caches, Finalized Output

- carry the post-snapshot output estimate into the context snapshot at
  finalize so the gauge keeps the last response after live resets
- accumulate per-rate billable units and price the session cost at
  render, so usage events arriving before the token-config load still
  count once it resolves
- pass user-scoped token-config cache keys through loadConfigModels
  fetches and drop the controller's unscoped fallback to prevent serving
  another user's resolved config
- tag emitted usage events with a per-run seq so resume dedupe never
  drops a distinct call with an identical payload
- admit the static tokenConfig override in the custom endpoint schema so
  it survives zod parsing into req.config

* 🩹 fix: Align Client Usage Accounting with Backend Cost Semantics

- classify cache tokens by provider (shared inputTokensIncludesCache from
  data-provider, consumed by both the backend billing path and the client)
  instead of a magnitude heuristic, so Anthropic/Bedrock turns where cache
  is smaller than uncached input no longer under-bill input
- mirror resolveCompletionTokens on the client so Vertex-style hidden
  thinking tokens are reflected in the Output row and session cost
- prefer endpoint pricing over adapter-provider pricing so a custom
  endpoint can price a known model name without built-in rates shadowing it
- carry static cacheRead/cacheWrite overrides through the tokenConfig
  schema and buildTokenConfigMap

* 🩹 fix: Honor Static Token Config in Billing; Tighten Usage Freshness

- initializeCustom now uses a static endpoint tokenConfig as the agent's
  endpointTokenConfig (billing + balance checks), not just the advertised
  UI config — previously the gauge showed admin rates while the agent
  billed against built-in tables
- invalidate the token-config query alongside models on user-key add/
  revoke so context windows and pricing refresh without a reload
- include maxContextTokens in ChatForm's stabilized conversation memo so
  the gauge reflects a changed context-window setting immediately
- feed the live output estimate from the legacy content path (direct and
  assistants streams), setting from cumulative part text rather than
  accumulating deltas

* 🩹 fix: Resume Usage Dedup, Agent Pricing, and Partial Override Billing

- fold usage events idempotently by (runId, seq) so resume backfill no
  longer resets the conversation totals — a mid-stream reconnect keeps the
  usage of prompts already completed earlier in the session
- tap replayed pending message/reasoning/content events so output streamed
  past the resume snapshot reaches the live estimate, not just the message
- resolve cost against the agent's backing endpoint (Agents conversations
  report endpoint `agents` / provider `openAI`, neither of which keys a
  custom endpoint's tokenConfig)
- getMultiplier/getCacheMultiplier fall back to the standard tables for
  models absent from a partial endpointTokenConfig, so a partial static
  override no longer bills non-listed models at defaultRate while the UI
  shows the correct pattern rate

* 🩹 fix: Repaired Output in Gauge, Cache-Rate Keys, Config Gate, Usage Cleanup

- live/completed gauge counts the repaired completion (normalized output),
  so under-reporting providers don't drop the response from used context
- translate static tokenConfig cacheWrite/cacheRead onto the write/read
  keys getCacheMultiplier reads, so cache tokens bill at the configured
  rate instead of the prompt-rate fallback
- clear the token index and usage atoms when leaving a conversation, so
  visited histories don't accumulate in memory for the tab's lifetime
- wait for startupConfig before mounting the gauge, so a deployment with
  contextUsage disabled never briefly mounts it or fires the token-config
  query on first load

* 🩹 fix: Move Token-Config Resolution to TS; Key Live Usage by Created Convo

- extract the token-config resolution (override gathering + cache lookup +
  buildTokenConfigMap) into resolveTokenConfigMap in packages/api, leaving
  the /api controller a thin request-scoped wrapper (CLAUDE.md TS rule)
- getConvoKey prefers the user message's real conversationId once the
  `created` event stamps it, so a new chat's first-response live gauge and
  totals land under the id TokenUsage subscribes to instead of NEW_CONVO

* 🩹 fix: Clear Stale Redis Job Usage; Live-Tap Legacy Streams; Share Fetched Config

- DEL the Redis job hash before re-creating it so a reused streamId can't
  inherit a prior run's contextUsage/tokenUsage and backfill stale usage
- tap the legacy {message,text} stream branch (non-agent OpenAI/Anthropic
  streams) into the live estimate, not just the content path
- copy a deduped fetch's token config to every sibling endpoint sharing the
  baseURL/key/headers, so /token-config resolves each by its own name

* ⏪ revert: Don't DEL Redis job hash in createJob (breaks cross-replica resume)

createJob is an idempotent join — a second replica calls it for the same
streamId to share an in-flight stream's state. DELeting the hash wiped the
prior replica's persisted created/usage state, so a joining replica missed
the created event (GenerationJobManager cross-replica integration test).
Reverts the F1 change from 2bfce0c34b; the stale-usage concern doesn't
arise in practice (streamId is unique per generation).

* 🩹 fix: Best-Effort Usage Emit; Tag Hidden Sequential-Agent Usage

- wrap the ModelEndHandler usage emit in try/catch so a failed telemetry
  delivery (closed SSE / Redis publish error) can't abort the handler
  before thought-signature capture, which would break resumed tool calls
- tag hidden sequential-agent usage as 'sequential' (non-primary) so the
  client folds it into session cost/totals but not the live context gauge,
  instead of letting an undefined usage_type inflate the visible gauge

* 🩹 fix: Refetch Stale Token Config on Mount; Normalize Vertex for Lookup

- useTokenConfigQuery refetches on mount when stale, so a user-key change
  that invalidates tokenConfig while the gauge is unmounted takes effect on
  return instead of serving the prior key's resolved config
- normalize a Vertex-backed agent's provider (vertexai) to the google
  token-config key, so Gemini context windows and rates resolve instead of
  showing unknown context / $0 cost

* ✨ feat: Server-Side Per-Event Cost (Authoritative Pricing for the Gauge)

Move usage-cost pricing to the single source of truth. The backend prices
each model call with the same billing functions (premium tiers via
getMultiplier(inputTokenCount), cache rates) and emits the USD cost on
on_token_usage when interface.contextCost is enabled; the client sums
emitted costs instead of re-deriving from base token-config rates.

- computeUsageCostUSD reuses prepareTokenSpend/prepareStructuredTokenSpend
  so the emitted cost matches what is billed (incl. premium thresholds)
- getDefaultHandlers gains a usageCost pricing context; initialize.js wires
  db.getMultiplier/getCacheMultiplier gated on contextCost (agents path)
- client UsageTotals carries a summed costUSD; retire the client-side rate
  lookups (costFromUnits/calcUsageCost) that drifted from backend pricing
  and produced the provider-keying / cache-key / Vertex / premium findings
- keep normalizeUsageUnits for the displayed token counts; token-config is
  still used for the context-window meter

Fixes the premium-tier session-cost under-report (gpt-5.x / gemini-3.1
above their input thresholds).

* 🩹 fix: Branch-Accurate Usage Snapshot + Clearer Gauge Track Contrast

- re-anchor the context snapshot from the user message to the response
  message at finalize. Regenerating a response branches off a shared user
  message, so anchoring on it made the snapshot read as "active" on both
  branches — switching to the sibling branch showed the wrong (other
  branch's) context. The response message is branch-unique, so sibling
  branches now correctly fall back to their own per-branch totals.
- raise the gauge ring's track/fill contrast (muted track, prominent fill)
  so the used portion reads clearly as a fill-level indicator

* 🩹 fix: Tag Sequential Usage in Billing; Emit Subagent Cost; Reset Live on Resume Errors

- tag hidden sequential-agent usage `usage_type: 'sequential'` on the
  COLLECTED usage (not just the emit), and treat it as non-primary in
  recordCollectedUsage (billed, excluded from the reported output total) so
  hidden intermediate output stops inflating the parent's tokenCount/pruning
- emit on_token_usage from the subagent usage sink (tagged `subagent`, with
  authoritative cost when contextCost is on) so the gauge's session
  cost/totals include billed subagent usage; it stays out of the live meter
- call resetLive on the resumable 404 and max-retry terminal branches so the
  gauge doesn't keep counting stale in-flight tokens after the stream ends

* 🎨 fix: Contrast the Popup Context Bar; Revert Ring Restyle

- raise the popup breakdown's context progressbar contrast (muted
  surface-tertiary track, prominent text-primary fill) — that's the bar the
  contrast feedback was about
- revert the gauge ring restyle (kept its original border-heavy track /
  text-secondary fill); the ring wasn't the element in question

* 🩹 fix: Stop Snapshot Granularity Leaking Across Branches; Revert Tree Memo

- a null-anchor context snapshot was treated as active on every branch,
  leaking one generation's granular breakdown onto sibling branches. Require
  a non-null (response-message) anchor on the viewed branch instead, so
  siblings without a matching snapshot fall back to their own totals.
- revert the buildTree WeakMap memo in messages.ts. buildTree is pure (builds
  from shallow copies) so the memo was behaviorally identical, but it was the
  feature's only change to core branch-navigation selectors — removing it
  matches upstream and rules it out of branch-navigation debugging.

* 🪙 fix: Thread Endpoint Token Config to Agent Billing, Cost, and Context Limits

Custom-endpoint agents resolve an endpointTokenConfig during agent init but
it never reached the AgentClient, so spending, emitted cost, and runtime
max-token resolution all fell back to default rates for those agents.

- Surface options.endpointTokenConfig on the returned InitializedAgent.
- Pass it to the AgentClient (this.options.endpointTokenConfig) so the
  spending path bills at configured rates.
- Thread it through usageCost to computeUsageCostUSD so emitted per-event
  cost matches billing.
- getModelMaxTokens/getModelMaxOutputTokens fall back to the built-in map
  for models absent from a partial override (matches buildTokenConfigMap);
  consolidates the duplicated fallback in pricing.ts.

* 🪙 fix: Preserve Granular Breakdown Across Branch Switches

The granular context breakdown lives only in the live on_context_usage
snapshot — a single per-conversation slot, anchored to the latest response
and overwritten by each generation. Switching to a branch generated earlier
this session lost its tool/skill/system rows and fell back to coarse totals.

Retain each generation's finalized snapshot in a per-conversation map keyed
by its branch-unique response id (snapshotsByAnchorFamily). When the live
snapshot is off the viewed branch, walk the branch tail for its deepest
stored anchor and render that breakdown. Bounded by generation count and
cleared on conversation switch; the live/just-generated path is unchanged.

* 🪙 fix: Harden Resume Seeding and Subagent Usage Emission

- useResumableSSE: skip the trailing-output live seed when the resume
  carries a context snapshot; the snapshot's messageTokens already counts
  produced output, so seeding it again inflated usage until the next reset.
- AgentClient subagent emitter: await GenerationJobManager.emitChunk like
  every other caller (it persists before publishing), so a floating promise
  can't race job cleanup and a Redis/publish failure is caught by the
  emitter's try/catch instead of surfacing as an unhandled rejection.

* 🧪 test: Playwright Coverage for Context Breakdown Granularity

Add a test-only data-testid distinguishing the granular snapshot breakdown
(context-breakdown) from the coarse message-history estimate
(context-estimate), then assert granularity in the mock e2e harness:

- renders the granular breakdown from the live on_context_usage snapshot
  (guards that the snapshot event actually reaches the popover, not just the
  usage totals).
- preserves the granular breakdown after switching branches — regenerate to
  overwrite the single live snapshot, switch back, and confirm the rows
  survive via the per-anchor snapshot history map.

Branch regenerate/sibling selectors mirror the existing chat.spec branch test.
All three usage specs pass against the mock pipeline.

* 🪙 fix: Correct Resume Live-Seed, Fallback Re-index, and Subagent Emit Flush

Codex round on the prior commit:

- countTrailingOutputChars now counts only output at the very END of the
  aggregated content (0 when the model paused at a tool call), and the resume
  path always seeds it. The earlier skip-trailing-tool-parts behavior plus the
  skip-seed-when-snapshot gate together over- or under-counted in-flight
  output on resume; one rule fixes both — pre-invoke snapshot budget is never
  double-counted, and genuine in-flight output is no longer dropped.
- useTokenUsage re-indexes from the messages cache on tail change while
  submitting. The cache subscriber is muted during streaming, so without a
  context snapshot (non-agent streams) sumBranch missed the created tail and
  dropped history + prompt until finalize. Bounded — tailId only shifts on
  created/finalize/branch-switch.
- AgentClient tracks subagent usage emit promises and flushes them in
  chatCompletion's finally. The sink fires the emitter without awaiting, and
  resume reads the usage emitChunk persists (HSET), so cleanup must not race
  it or resumed clients miss billed subagent usage.

🗄️ 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.

* fix: Coerce scalar skill frontmatter and correct scheduler timer clear

- parse: coerce numeric/boolean name and description scalars to strings instead of dropping them to empty (restores pre-refactor behavior; preserves absent-vs-empty distinction for the when-to-use fallback)
- scheduler: clear the setTimeout handle with clearTimeout rather than clearInterval
- test: cover non-string scalar frontmatter coercion

* fix: Tolerate trailing whitespace after SKILL.md opening frontmatter fence

extractFrontmatterBlock required the opening fence to be exactly '---\n', so an opener with trailing spaces/tabs (e.g. '---   \n') silently dropped all frontmatter even though the closing-fence regex already tolerates it. Match the opener with /^---[ \t]*\n/ for symmetry. Addresses Codex P3 (parse.ts:24).

* feat: Run GitHub skill sync under a per-source tenant context

Under TENANT_ISOLATION_STRICT, the sync ran with no async tenant context, so the tenant-isolation mongoose hooks threw on every Skill/SkillFile/AclEntry operation; in non-strict mode synced skills were written tenant-less and never matched tenant-scoped reads. Add an optional per-source tenantId to the skillSync config; when set, each source sync runs inside tenantStorage.run({ tenantId }) so skills, files, and public ACL grants are created and listed within that tenant, and the skill row is stamped with the tenantId for correct dedup. Sources without tenantId keep the prior single-tenant behavior. Avoids runAsSystem. Addresses Codex P2 (sync.js:70).

Lock/status/credential bookkeeping stays outside the tenant context (those collections are intentionally global).

* test: Restore dropped tenant-context coverage for GitHub skill sync

The prior commit shipped the getTenantId import in github.spec.ts without the tenant tests that use it (lost in an interrupted edit), which failed the eslint --max-warnings=0 CI job on an unused import. Restore both github.spec.ts tenant tests (tenant-scoped run stamps tenantId and executes inside the tenant ALS context; no-tenant run stays ambient) and the two config-schemas tenant tests (accepts tenantId, rejects __SYSTEM__).

* test: Restore dropped github.spec tenant-context tests

The previous commit's github.spec.ts edit did not apply (anchor mismatch), so the getTenantId import remained unused and failed eslint --max-warnings=0. Add the two tenant tests that use it: a tenant-scoped run stamps tenantId and executes inside the tenant ALS context, and a no-tenant run stays ambient.

* feat: Scope synced skill author to tenant and harden tenant-context sync

Addresses the latest Codex review on the per-source tenant change:
- makeSourceAuthorId now folds tenantId into the synthetic author hash so the
  same source mirrored into different tenants gets distinct author ids (clearer
  audits, no cross-tenant author collisions). Single-tenant author ids stay
  stable (suffix omitted when tenantId is absent).
- syncSourceInTenantContext uses an async callback per the tenant-context
  contract so the ALS store propagates across awaited Mongoose calls.
- Tests: same-source/different-tenant yields distinct authors; mirror cleanup
  is scoped to the source and deletes only its absent-upstream skills.

* fix: Repair tsc error and guard external edits in github skill sync

- Fix TS2352 in github.spec mirror-cleanup test: build the existing-skill mock via makeSkill with authorName instead of an under-typed 'as CreateSkillInput' cast (this was the failing TypeScript CI check on f00ce3c5a).
- 808: commitExistingRemoteSkillAfterFileSync re-reads to clear our own file-sync version bumps, but now compares refreshed content against the pre-sync snapshot (body/name/description/always-apply) and throws SKILL_CONFLICT on a concurrent external edit instead of overwriting it.

* docs: Note skillSync source tenantId is effectively immutable

Changing/adding/removing a source's tenantId orphans previously mirrored skills in the old tenant (a tenant-scoped sync cannot clean another tenant's data without runAsSystem, which is intentionally avoided).

* fix: Key GitHub skill upstream identity on source id and path only

Addresses Codex finding (github.ts:217): makeUpstreamId previously included owner/repo, so repointing a source to a renamed or replacement repository (same source id) changed the upstreamId, made findSkillBySourceIdentity miss the existing mirror, and then collided on the (name, author, tenantId) uniqueness constraint — leaving the source stuck failing. Identity now keys on the stable source id + root path only. The feature is unreleased, so there is no stored-id migration. Updated spec upstreamId fixtures to the new format; the existing ref-independent identity test now also covers repo moves.

* fix: Scope GitHub skill mirror deletion to the source tenant

Addresses Codex P1 (github.ts:1047/1057): an ambient source (no tenantId) runs listSkillsBySource without tenant context, which under non-strict isolation returns github-synced skills across all tenants. The mirror-deletion pass then treated other tenants' skills as absent-upstream and could delete them. Filter existingSyncedSkills to rows whose tenantId matches the source's configured tenantId (absent = its own ambient bucket) before deleting, so a sync never removes another tenant's mirrored skills. Covered by a test where an ambient run leaves a tenant-b-owned skill untouched.

* fix: Apply tenant-scoped mirror deletion implementation

The prior commit (75ccfa3fc) added the test but the source change to github.ts was lost in an interrupted edit, leaving a failing test with no implementation. This adds the actual guard: the mirror-deletion pass skips skills whose tenantId does not match the source's configured tenantId (absent = ambient bucket), so an ambient source whose listSkillsBySource returns cross-tenant rows under non-strict isolation cannot delete another tenant's mirrored skills.

* fix: Resolve global access role outside tenant context for synced skill grants

Addresses Codex P2 (github.ts:1166): default access roles (incl. skill_viewer) are seeded globally with no tenantId under runAsSystem, but a tenant-scoped sync wraps ensurePublicViewer in the source's tenant context. The PermissionService grantPermission resolved the role via a tenant-isolated AccessRole query, so the global role did not match and tenant-scoped syncs failed with 'Role skill_viewer not found'. The sync adapter now resolves the role inside runAsSystem (matching the global seed) and writes the ACL entry in the active tenant context, so the AclEntry is tenant-scoped (visible to tenant users) while the role lookup still succeeds. Covered by service tests for the resolve-vs-write split and the missing-role failure.

* fix: Strip placeholder frontmatter booleans and check skill conflict before file sync

- 1083 (github.ts:759): toCleanFrontmatter now drops a non-boolean always-apply (e.g. the 'always-apply:' / 'always-apply: # TODO' placeholder, which js-yaml yields as null). The boolean is already captured in the dedicated alwaysApply field; persisting null left ambiguous frontmatter on the synced skill.
- 1080 (github.ts:1057): for an existing mirrored skill, check for an external content edit (via getSkillById + hasExternalSkillEdit) BEFORE syncSkillFiles mutates the bundled files, so a concurrently edited skill fails fast with SKILL_CONFLICT without partial file rewrites. The post-file-sync check still guards edits that land during the file sync window.
Tests: placeholder always-apply is dropped from synced frontmatter; concurrent-edit conflict leaves files unmutated (no upsert/delete).

🤫 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.

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

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

* 🧪 test: Memoize compiled patterns + add middleware spec

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

⏳ fix: Extend and Decouple MCP OAuth Flow Timeouts (#13622)
* ⏳ fix: Extend and decouple MCP OAuth flow timeouts

The OAuth auth button disappeared after 2 minutes (the internal OAuth
handling timeout) while the flow state lived for 3 minutes, leaving users
who didn't click immediately stuck in an unrecoverable re-auth loop. The
handling timeouts also reused the connection/init timeout, so a short
initTimeout would shrink the OAuth window further.

- Add MCP_OAUTH_HANDLING_TIMEOUT (10m) and MCP_OAUTH_FLOW_TTL (15m) to mcpConfig
- Decouple the reactive/proactive OAuth waits from initTimeout/connectionTimeout
- Use OAUTH_FLOW_TTL for the FlowStateManager TTL and the UI status window
- Ensure the flow TTL outlives the handling timeout, fixing the
  "Flow state not found" race
- Remove dead FLOW_TTL constant and document new env vars

Fixes #13615

* ⏳ fix: Coordinate OAuth pending window with handling timeout

Address Codex review: the extended OAuth wait was still capped by other
timeouts that were not updated.

- Align PENDING_STALE_MS (button validity + pending-flow reuse window)
  with MCP_OAUTH_HANDLING_TIMEOUT so a flow stays reusable for the full
  wait instead of 2 minutes (Finding 3)
- Clamp MCP_OAUTH_FLOW_TTL to never fall below the handling timeout so a
  callback near the deadline still finds its flow state (Finding 2)
- Floor attemptToConnect's timeout to the handling window for OAuth
  servers so the reactive in-connect OAuth wait is not killed by the
  30s connection timeout (Finding 1)
- Update flow staleness tests to reference the threshold symbolically

* ⏳ fix: Align OAuth window across status, action flows, and client polling

Address Codex round 2: extending the server wait exposed three more
windows that were still capped or now over-extended.

- checkOAuthFlowStatus reports a PENDING flow as active only within the
  usable PENDING_STALE_MS window, not the longer Keyv retention TTL, so
  the connect button reappears instead of a stuck 'connecting' state
- Give Action (custom tool) OAuth its own FlowStateManager on the prior
  3-minute TTL so the longer MCP OAuth TTL can't leave an action tool
  call waiting up to 15 minutes
- Extend the MCP server-card client polling to the 10-minute handling
  window so a user who completes OAuth after 3 minutes is still picked up

* 🧪 test: Make stale-flow CSRF test track PENDING_STALE_MS

The CSRF-fallback stale-flow test hardcoded a 3-minute age, which is now
within the 10-minute PENDING_STALE_MS window and was wrongly treated as
active. Derive the age from PENDING_STALE_MS so it tracks the constant.

* ⏳ fix: Add grace buffers and surface OAuth timeout to the client

Address Codex round 3 (near-deadline edges):

- Clamp MCP_OAUTH_FLOW_TTL to handling timeout + 60s grace (not equality),
  so flow state outlives the wait instead of expiring at the same instant
- Extend attemptToConnect's OAuth floor by a 60s grace so a user who
  authorizes near the deadline still gets the post-OAuth reconnect
- Surface OAUTH_HANDLING_TIMEOUT on the connection-status response and
  have the client poll for the configured window instead of a hardcoded
  10 minutes, so a tuned server deadline isn't capped on the client

* ⏳ fix: Refresh client OAuth timeout from the first status refetch

If the connection-status cache is empty when polling starts, the client
captured the 10-minute fallback and never picked up a tuned oauthTimeout.
Re-read it after each refetch so a longer configured deadline is honored
even on a cold cache.

* 📝 refactor: Type oauthTimeout on MCPConnectionStatusResponse

Declare the oauthTimeout field on the shared response type in
data-provider instead of an ad-hoc inline cast in the client hook, and
replace the pre-existing 'as any' on the status query read with the
typed getQueryData. Type-level only; no runtime change.

* feat: surface message feedback (thumbs up/down) as Langfuse scores

When Langfuse tracing is enabled, the message feedback endpoint now posts a
boolean `user-feedback` score (1/0 + tag/comment) to Langfuse for the
assistant message's trace; clearing feedback deletes the score. Fire-and-
forget, so the feedback UX never blocks on Langfuse.

Linking is lookup-free: the run opts into deterministic Langfuse trace ids
(`langfuse.deterministicTraceId`, passed to the agents Run), so the trace id
is sha256(messageId)[:32]. The feedback route recomputes the same id and
scores by it.

- api/server/services/Langfuse.js: POST/DELETE /api/public/scores (env-gated)
- api/server/utils/langfuseTrace.js: traceIdForMessage(messageId)
- api/server/routes/messages.js: fire feedback score after the Mongo write
- packages/api: pass langfuse.deterministicTraceId to the run
- bump @librechat/agents to ^3.2.21 (adds LangfuseConfig.deterministicTraceId)

Closes #13537

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix: match Langfuse trace environment for feedback scores

@librechat/agents passes no environment to its Langfuse tracer, so
@langfuse/otel falls back to LANGFUSE_TRACING_ENVIRONMENT and otherwise to
Langfuse's "default". The score helper instead fell back to NODE_ENV, so a
deployment with only NODE_ENV=production filed scores under "production" while
the trace stayed on "default" — the score never landed on the trace.

Use LANGFUSE_TRACING_ENVIRONMENT only, and omit `environment` when unset so
Langfuse defaults both score and trace to "default".

Addresses Codex review on #13544.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix: don't require LANGFUSE_BASE_URL to post feedback scores

The agent tracer emits traces with just the public/secret keys (defaulting to
Langfuse Cloud, or via the legacy LANGFUSE_BASEURL alias), but the score helper
disabled itself unless LANGFUSE_BASE_URL was set — so an otherwise-traced
deployment silently posted no scores. Resolve the base URL the same way the
tracer does (LANGFUSE_BASE_URL -> LANGFUSE_BASEURL -> Cloud) and gate enablement
on the credentials only.

Addresses Codex review on #13544.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix: only post feedback scores for agent-endpoint messages

The feedback route is shared by all message types, but deterministic Langfuse
trace IDs are only enabled for agent runs. Rating a message from a non-agent
endpoint (with Langfuse configured) posted a user-feedback score for
sha256(messageId) that no trace will ever match, leaving orphan scores.

Gate scoring on isAgentsEndpoint(message.endpoint); `updateMessage` now returns
`endpoint` so the route can check it.

Addresses Codex review on #13544.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix: gate feedback scoring by !isAssistantsEndpoint, not isAgentsEndpoint

The previous gate used isAgentsEndpoint, which only matches the literal
`agents` endpoint. But provider endpoints (anthropic, openai, custom, …) run
through the agents runtime as ephemeral agents and DO emit deterministic
AgentRun traces, so isAgentsEndpoint('anthropic') === false suppressed scoring
for the common case. Only the OpenAI/Azure Assistants endpoints use a separate
runtime with no agent trace, so gate on !isAssistantsEndpoint instead.

- Add ProjectsSection: collapsible project rows that unfurl chats inline
  (full-size rows), with per-project new chat and an open/rename/delete menu
- Lift the marketplace/favorites shortcuts above the Projects section

Chat scope
- Derive a new chat's project strictly from the URL ?projectId, so the
  global New Chat no longer stays stuck in a project after a project chat

Surfaces
- Chat landing: subtle, clickable project chip instead of the floating badge
- Project workspace: modest header, composer-style entry, chats list
- All-projects grid: Claude-style cards with pluralized chat counts

* chore: prune unused i18n keys; fix project chat-count pluralization

* fix: project new-chat keeps model spec; sidebar header + row polish

- newConversation: ignore a chatProjectId-only template when deciding to
  apply the default model spec, so starting a chat in a project no longer
  strips the conversation `spec`
- useSelectMention: the Model Selector and @ command now retain the active
  project across endpoint/spec/preset switches; other new-chat paths still
  clear it
- Chats header now matches the Projects header (inline chevron + a new-chat
  icon button) and starts a non-project chat
- Project rows: use the new-chat icon for the per-project add button, render
  at text-sm to match the chat list, and align the row actions + hover color
  with conversation rows

* fix: read project scope from router params; align sidebar header icons

- useSelectMention now reads the active project from React Router's search
  params instead of window.location, which can drift out of sync because
  new-chat params are written to the URL via raw history.pushState; the
  Model Selector and @ command now reliably keep the project on switch
- Move the Chats section header out of the virtualized list so it renders
  in the same context as the Projects header and isn't shifted by the
  list scrollbar
- Inset header action icons (pr-2) so Projects/Chats header icons line up
  with the project-row and conversation-row trailing actions
- Extract getRouteChatProjectId into utils for the submit path

* fix: preserve chatProjectId through the new-chat template reduction

The param-endpoint guard in newConversation reduced a new chat's template to
{ endpoint } only, dropping the chatProjectId injected by the Model Selector /
@ switch — so switching models cleared the project scope. Keep chatProjectId
in the reduced template.

* style: align chat-history panel top padding; improve projects page contrast

- Add pt-2 to the chat-history panel so its top spacing matches the other
  side panels (agent builder, skills, files, etc.)
- Projects grid + workspace now use the darkest surface for the page
  (surface-primary) with cards, inputs, and the composer one step lighter
  (surface-secondary) and tertiary on hover, so cards read as elevated
  rather than darker than the background

* feat: interactive project landing chip + gallery icon for all-projects

- All-projects sidebar button uses the gallery-vertical-end icon
- The project landing chip is now interactive: click it to switch projects
  via a searchable combobox (ControlCombobox), or the trailing × to drop the
  project scope. Both update the draft conversation and the ?projectId search
  param in place, so the typed message and selected model are preserved

* test: fix Conversations unit test for refactored sidebar; add projects e2e

- Update Conversations.test.tsx mocks for the inline Chats header
  (useNewConvo, useQueryClient, conversation atom, NewChatIcon, TooltipAnchor),
  drop the removed chatsHeaderControls prop, and remove the mock for the
  deleted ../Header module — fixes the failing frontend Jest job
- Add e2e/specs/mock/projects.spec.ts covering project creation, the
  project-scoped new-chat landing + interactive chip (switch/remove), and
  listing projects on /projects
- Give the landing chip combobox a stable selectId for reliable targeting

* fix: refresh project stats after project-chat activity; stabilize e2e

- useEventHandlers: when a project chat is created/updated, invalidate the
  live [projects] query (gated on chatProjectId) instead of the now-unused
  projectConversations key, so the sidebar + all-projects stats refresh
  after a streamed reply (addresses a Codex finding)
- projects e2e: assert the reliable project-landing behavior (chip, scoped
  composer, accepted send) rather than the /c/:id transition, which the
  mock LLM harness doesn't complete

* test: verify a project chat saves and is filed under its project (e2e)

- Switch to a mock endpoint before sending so the message streams without a
  real API key (the default model failed with "No key found", so no chat was
  saved and the page never left /c/new); this also asserts the project chip
  survives the model switch
- Restore the reply + /c/:id transition assertions and add a check that the
  chat is listed under the expanded project in the sidebar
- Add data-testid="project-chats-<id>" to the inline project chat list

* fix: address Codex review findings (project scope edge cases)

- useSelectMention: fall back to the conversation's chatProjectId when the
  URL has no projectId, so switching model/spec inside an existing project
  chat (/c/:id) keeps the project assignment
- Conversations: include chatProjectId in the MemoizedConvo comparator so a
  sidebar row's project menu doesn't stay stale after a reassignment
- useDeleteProjectMutation: clear the active conversation's chatProjectId
  when its project is deleted (mirrors the assignment mutation); drop the
  now-dead projectConversations invalidation
- useQueryParams: carry the project into the new conversation when applying
  URL settings, so /c/new?projectId=...&<settings> stays scoped

* fix: project stats pagination + archived-chat edge cases (data-schemas)

- listChatProjects: include the null lastConversationAt bucket in the desc
  cursor so empty projects paginate (a $lt:<date> predicate excluded nulls,
  hiding chat-less projects from "Load more")
- saveConvo: recompute project stats instead of the incremental fast path
  when the saved conversation is itself archived/temporary/expired, so a
  project's lastConversationAt/Id no longer points at a hidden chat

* test: cover chat-less project pagination across the dated→null boundary

* fix: validate project ownership in bulkSaveConvos

Bulk paths (import/duplicate/fork) persisted whatever chatProjectId the
payload carried; an id that does not belong to the user created an orphan
assignment hidden from both the project and the unassigned sidebar. Validate
ownership like saveConvo and strip un-owned project ids before persisting,
refreshing stats only for owned projects.

* fix(projects): preserve chatProjectId on continuation, basename-safe delete redirect, project-detail invalidation

* fix(projects): navigate project workspace chats via useNavigateToConvo to avoid stale conversation state

* fix(projects): include projectConversations cache when resolving deleted chat's project for detail invalidation

* fix(projects): refresh both projects when a save or bulk write moves a chat between them

* style(projects): use Folders icon for the sidebar Projects header

* fix(projects): require id on ProjectUser so ProjectRequest extends Express Request cleanly

* style(projects): taller project chip with hover-revealed remove button, upward combobox; sort en translations

* style(projects): show endpoint/agent icon for project workspace chat rows

🔗 feat: Add Granular Access Control to Shared Links via ACL System (#13051)
* feat: Add granular access control to shared links via ACL system

* fix(shared-links): preserve isPublic on failed migration grants

Transient ACL failures during auto-migration permanently stranded
links — $unset ran unconditionally, removing the legacy flag that
triggers retry. Now only $unset isPublic after all grants succeed.

* fix(config): skip isPublic unset for failed ACL grants

Bulk migration unconditionally removed isPublic from all links,
even those whose ACL writes failed. Failed links then lost the
legacy marker needed for auto-migration retry. Now tracks failed
link IDs per-batch and excludes them from the $unset step.

Also adds sharedLink to AccessRole resourceType schema enum —
was missing, only worked because seedDefaultRoles uses
findOneAndUpdate which bypasses validation.

* ci(config): add jest config and PR workflow for migration tests

config/__tests__/ specs depend on api/jest.config.js module
mappings but had no dedicated runner. Adds config/jest.config.js
extending api config with absolutized paths, npm test:config
script, and a GitHub Actions workflow triggered by changes to
config/, api/models/, api/db/, or packages/ ACL code.

* fix(permissions): honor boolean sharedLinks config

SHARED_LINKS has no USE permission, so boolean config produced
an empty update payload — gate conditions only matched object
form, making `sharedLinks: false` a no-op on existing perms.

* fix(share): resolve role before creating shared link

Role lookup between create and grant left an orphaned link
without ACL entries if getRoleByName threw — retry then hit "Share already exists" with no recovery path.

* fix: Restore Public ACL Access Checks

* fix: Type Public ACL Lookup

* fix: Preserve Private Legacy Shared Links

* chore: Promote Shared Link Permission Migration

* fix: Address Shared Link Review Findings

* fix: Repair Shared Link CI Follow-Up

* ⚡ feat: Immediate Conversation Title Generation

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

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

* 🩹 fix: Address Copilot review findings on title timing

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

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

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

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

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

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

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

Follow-up to codex review:

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

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

Follow-up to codex review:

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

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

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

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

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

* 🧪 test: Cover useTitleGeneration effect logic (integration)

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

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