Danny Avila	8a46ca070c	🧊 feat: Persist Context Fading Tier Across Agent Runs (#15505) ... * 🧊 feat: Persist Context Fading Tier Across Agent Runs Carry the pruner's latched context-fading tier from `@librechat/agents` through `contextMeta` the way `calibrationRatio` already travels, so a historical tool result keeps the same truncated bytes from one run to the next and Anthropic's prefix-based prompt cache survives across turns (danny-avila/agents#497). - Add `IAgentFadingTier` to the message and conversation `contextMeta` types, schemas and the data-provider zod schema - Add `isAgentFadingTier`, `resolvePersistableFadingTier` and `resolveRunContextMeta` in `packages/api`; a tier is persisted once it carries information (masking active or a budget below the window), and a latched tier is kept even at a neutral calibration ratio - Seed `createRun({ fadingTier })` from the parent response's contextMeta regardless of encoding, since caps are character-based; the field rides the existing forward-compatible `runConfig` variable and older SDK versions ignore it, as does `Run.getFadingTier` being absent - Accept a valid `fading` field in event actor context and reject a malformed one, matching the calibration checks - Capture run context meta through one module-level helper for both completion paths instead of two inline copies Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Seed Fading Tier Across HITL Resume, Validate at the DB Layer Address review findings on fading tier persistence: - Leave the "is this tier worth persisting" decision to the SDK, whose `Run.getFadingTier()` now returns only informative tiers; comparing against the client's window misclassified untouched conversations whenever a reserve ratio was configured - Carry `contextMeta` through the HITL pause projection (staged approval, job metadata, resume state) and seed the rebuilt client from it, so a paused turn resumes with the same tier and calibration instead of re-deriving a shallower one and rewriting the prefix - Share run seeding between `chatCompletion` and `resumeCompletion`, and make capture tolerate partial runs and bare resume contexts - Validate `contextMeta.fading` in `commitAgentEventActorState` with a shared `isAgentFadingTier` guard in data-schemas, so a malformed tier is rejected at the DB layer instead of silently cold-starting the actor - Reuse `IAgentEventActorContextMeta` for `IMessage.contextMeta` instead of extending an inline duplicate Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 test: Cover Resume Seeding From Paused Context Meta Assert the resume controller seeds the rebuilt client from the context meta captured at the pause before rebuilding the run, and move the capture helper's JSDoc back above its function.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Fence Context Meta Publication Ahead of Stop A Stop handled by another replica reads the job before the owner is signaled, so a fire-and-forget publish could lose the race, and a run stopped before its first context snapshot never published the tier it inherited. The client now publishes the inherited seed before the run streams or resumes, and the context-usage handler awaits each snapshot's publish so the write lands before the model call it describes begins. Failures still only log; the pre-run publish is optional-called so bare resume contexts keep working. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Read Back Context Meta After the Abort Claim The run owner publishes its context meta ahead of each model call and awaits the write, so a publish landing between the abort's initial job read and its terminal claim describes the call whose partial output the abort snapshot carries. abortJob now reads the same-epoch job back after the claim and content re-read and takes its context meta, so the stopped response persists the tier that produced its bytes. The refresh is best-effort and logs on failure like the content refresh beside it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Share In-Flight Context Meta Writes and Clear Neutral Live State Two snapshot callbacks in a parallel-agent run can capture the same tier before the first write settles; the publisher now caches the in-flight promise per serialized value so the second caller awaits the same durable write instead of treating an uncommitted value as published. A live snapshot with nothing left to persist after an earlier publish now writes a neutral record (ratio 1, no tier), since a running job's fields cannot be deleted through the metadata writer, so a Stop no longer persists an earlier non-neutral state onto the response. The pre-run seed publish is unchanged and is told apart from live snapshots by a flag from the context-usage sink. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 chore: Drop Unused Rest Parameter in Context Meta Test Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 feat: Persist Per-Agent Fading Tiers as Compact Context Meta Reconciles the host with @librechat/agents at 9aacad1a, where graph history stays canonical and each Run derives a provider-only projection from the latched tiers. LibreChat therefore persists only compact state: the calibration ratio, the default agent's tier, and now the per-agent tiers from Run.getFadingTiers(), stored as validated entries so agent IDs never become MongoDB field names and restored onto a null-prototype record for RunConfig.fadingTiers. Truncated messages, canonical tool content, projection provenance and per-message truncation state are never persisted; the SDK's latched flag is stripped on capture. The per-agent map travels everywhere the single tier already did: response contextMeta, event-actor checkpoint state, HITL pause and resume job metadata in both stores, the Stop path, and branch creation. A shared Mongoose definition keeps the message and conversation schemas identical, the zod schema validates entries, and commitAgentEventActorState rejects malformed maps. Comments no longer describe graph messages as truncated; only the provider projection is. Tests cover: tool results and inputs reach the persisted content parts at full size; contextMeta carries exactly the compact tier and calibration fields; a persisted snapshot round-trips into the seeded RunConfig unchanged and prototype-safe; per-agent tiers survive pause, Redis job round-trips, and event-actor context validation. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Restore Event Actor Types and Publish Seeds Before Abortable Setup The previous commit's doc rewording in the conversation types dropped the event-actor interfaces that precede the fading tier, which broke the declaration bundle in CI; they are restored unchanged. The inherited context meta is now published onto the job as soon as the parent's state is loaded and awaited at the top of chatCompletion and resumeCompletion, ahead of run creation and the other abortable setup stages, so a Stop during setup still persists the parent's tiers onto the stopped response. The partial response saved when every subscriber disconnects now carries the job's context meta like the Stop and pause paths do. The branch route keeps the source's context meta in the saved message but strips it from the HTTP response, matching client reads. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Serialize Distinct Context Meta Publications Overlapping snapshots from parallel agents could carry different tiers; each started its own write and both job stores keep whichever write finished last, so an older snapshot could overwrite a newer one. Each distinct publication is now issued after the previous one settles, in call order, so the newest snapshot is what a Stop reads back. Equal values still share one write. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Project Root Message Reads and Keep Inherited Meta on Setup Failure The root GET /api/messages paths returned raw documents: the single-message query read called getMessages without a projection and the cursor page performed an unprojected find. Both now apply CLIENT_MESSAGE_SELECT, with getMessagesByCursor accepting a select option, so the persisted fading tiers never reach the client through the paginated endpoint; the search-hydration read projects the same way. A turn that loads a parent's context meta but fails before its run exists used to replace the inherited meta with the capture of a missing run, so the persisted error response lost the last valid tiers. Both finalizers now keep the inherited meta when no run was created while a created run's neutral state may still clear it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 refactor: Move Context Meta Publication Into packages/api The publication coordinator (ordering, deduplication, in-flight sharing, failure state) now lives in packages/api as createContextMetaPublisher, with selectRunContextMetaToPublish deciding what a publication carries; the legacy client keeps only the wiring to the job metadata writer. A transiently failing write is retried with a short backoff before the publication is reported and forgotten, so a snapshot's model call no longer proceeds on the first rejection while the job holds the previous record. The SDK swallows handler errors, so retrying is the only way to strengthen the fence without failing the turn. A terminal save now supplies contextMeta: null when the finished run has nothing to carry, and saveMessage unsets a previously stored value in that case, so a disconnect snapshot's record cannot outlive the run that completed neutrally. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Widen the saveMessage Method Type for the Null Unset The exported method interface still typed contextMeta as the message field, so the spec exercising the null unset failed typechecking; it now mirrors the implementation signature. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Publish Every Agent's Snapshot, Sanitize Search Hits, Unbound Agent IDs The context-usage handler now awaits the run's context meta publish for every ON_CONTEXT_USAGE event, hidden sequential agents included, while the visible-snapshot bookkeeping and the client emission keep their gate; a Stop before the next visible snapshot finds the tier a hidden agent's model call latched. Search results are built from the hydrated hit minus its server-private contextMeta, since Meilisearch hydration projects every schema field. The per-agent tier entry guard no longer caps the agent ID length: ephemeral agent IDs encode endpoint, model and sender without a bound, and dropping such an entry would let that agent alone re-derive its tier on the next turn. Also formats the publication spec so the static checks pass. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Unset Context Meta Atomically, Keep Publication State After a Failed Write - `saveMessage` folds the `contextMeta` unset into the same update that persists the terminal response, on both the plain and the provenance-merge paths, so a failure between two writes can no longer leave a completed row carrying a disconnect snapshot's state. - `createContextMetaPublisher` tracks whether any record has committed separately from the retryable latest publication, so `hasPublished` stays true after a later publication exhausts its retries and a following neutral snapshot still overwrites the earlier record on the job. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Carry Context Meta Through the Resumable Stop Route and Neutral Resumed Completions - The resumable Stop route copies the refreshed `jobData.contextMeta` onto the terminal assistant message it persists, as the abort middleware already does, so a stopped resumable response keeps the tiers that produced its partial output. - A resumed run that completes with neutral context state now saves `contextMeta: null`, which unsets the paused segment's record instead of letting an omitted field keep it on the completed row. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Trust Only Server-Authored Context Meta, Unset It on a Neutral Stop, Read It From the Job on Disconnect - `POST /api/messages/:conversationId` and conversation imports drop any client-supplied `contextMeta`, and the run seeds its calibration and fading tiers only from a server-authored parent response, so a forged tier can never shape a provider projection. - Both Stop paths save `contextMeta: jobData.contextMeta ?? null`, so a job that re-paused with neutral state unsets what an earlier pause stored on the row instead of leaving it behind. - The disconnect partial save reads the same-epoch job record for the run's published context meta, since the client-facing resume snapshot never carries server-private state. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧪 test: Mock the Job Store in the Resume Metadata Spec The disconnect partial save now reads the same-epoch job record through `GenerationJobManager.getJobStore()`, so the resume metadata spec's manager mock provides it as the other disconnect spec already does. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 🧊 fix: Keep Context Meta Off the POST Message Response `POST /api/messages/:conversationId` returned the saved row verbatim, so a client write against an existing server-authored message echoed the row's stored context meta. The route now projects the row through the same client projection the branch route uses, which drops the server-private field. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WNbgMeR2aZDyhsqAy4L8gF * 📦 chore: Bump @librechat/agents to 3.7.16 for Persisted Fading Tiers 3.7.16 is the first release that carries danny-avila/agents#497, so `Run.getFadingTier()` / `getFadingTiers()` now report the latched tier this branch persists and `RunConfig.fadingTier` / `fadingTiers` seed the next run from it. The dependency set is unchanged from 3.7.15; only the package entry moves. Adds an SDK-backed round trip to the fading spec: a first pruner latches an informative tier, `resolveRunContextMeta` reduces it to the persisted shape, and a second pruner seeded from that shape reproduces the first run's projected tool-exchange bytes under instruction and calibration drift, while an unseeded pruner under the same drift relaxes its tier and rewrites them.

Danny Avila	29f738dea8	⏭️ feat: Honor an Interrupt Before the Model Has Answered (#15491) ... * ⏭️ feat: Honor an Interrupt Before the Model Has Answered An interrupt armed while the model is still thinking sat as "Interrupting" until the entire turn finished, then landed as a terminal continuation. The cause is upstream: the SDK reads `shouldPreempt` once per streamed chunk, and its seal gate requires non-empty text — so a silent provider is never polled at all, and a reasoning-only turn is never sealable. `@librechat/agents` gains a discard-and-restart path for exactly that window (`HOOK_PREEMPT_RESTART_CAPABLE`). This wires the host half: - `GenerationJobManager.subscribePreempt` registers run-scoped wake listeners, notified after an ACCEPTED arm — local or cross-replica, since both land in `armPreemptIds`. Fenced on `createdAt` like every other preempt entry point, and a throwing listener never fails the arm a queued steer depends on. - `createSteerPreemptPoll` hands that channel to the SDK as `StreamPreemption.subscribe`, gated on a new `isSteerPreemptRestartSupported` probe so an SDK that cannot act on a wake is never handed one. The wake is a hint only: `isPreemptRequested` stays the single authority, so the level-triggered contract the seal path depends on is unchanged. Inert until `@librechat/agents` publishes the restart contract — the probe returns false against the pinned 3.7.11 and the run keeps today's behavior. * 🩹 fix: Replay an Already-Armed Preempt on Subscribe Preempt requests are level-triggered, and the window between a job becoming steerable and the SDK installing its model-attempt listener is real. An interrupt landing there was recorded with no callbacks to notify, and on a silent or reasoning-only turn no later chunk poll may ever run — leaving the request to wait out the whole turn, the exact stall this channel removes. `subscribePreempt` now replays an existing arm to the newly registered listener only, after registration: waking the whole set would re-notify runs that already looked, and waking before registration would leave a concurrent arm with nowhere to land. The `createdAt` fence is unchanged and still gates the replay. The SDK also reads the level flag once at each attempt's start, so this is belt-and-braces rather than the sole cover — but it makes the host correct on its own terms instead of resting on when the SDK happens to look. * 🔧 chore: Update @librechat/agents dependency to version 3.7.14 in package-lock.json and related package.json files * 🔧 chore: Update dependencies in package-lock.json and package.json - Bump versions for @humanfs/core (0.19.1 to 0.19.2), @humanfs/node (0.16.6 to 0.16.8), @xmldom/xmldom (0.8.13 to 0.8.15), and qs (6.15.2 to 6.16.0). - Add @humanfs/types (0.15.0) as a new dependency for @humanfs/node. - Update dependencies for side-channel and side-channel-list to their latest versions.	2026-09-02 13:35:52 -04:00
Danny Avila	0219513115	🛑 fix: Forward Run Abort Signal to Foreground Tool Calls (#15517) ... * 🛑 fix: Forward Run Abort Signal to Foreground Tool Calls Stopping a generation left in-flight tool calls running on the far side. For MCP over streamable-http the external server kept burning CPU until the tool finished or timed out, with no `notifications/cancelled` ever sent. The MCP layer was never the problem: `MCPManager.callTool` already spreads `options.signal` into `client.request`, and the SDK's `Protocol.request` sends `notifications/cancelled` the moment that signal aborts. The signal simply never arrived. Agent tools do not execute inside LangGraph's ToolNode — `eventDrivenMode` dispatches `on_tool_execute` and `createToolExecuteHandler` invokes them. The agents SDK puts the run's abort signal on the batch request (`ToolExecuteBatchRequest.signal`, documented as one handlers should forward), but the handler destructured every field except `signal` and built its invoke config without it. `config.signal` was therefore `undefined` in every foreground tool, so `createMCPTool` derived no signal and the SDK registered no abort listener. Forward it. This restores cancellation for all signal-aware foreground tools, not just MCP. The detached background invoke keeps its own controller, since that work deliberately outlives the turn. An aborted call now rejects promptly and resolves an error result rather than hanging, so the abort is logged at debug instead of as a tool error — a user pressing Stop should not spray the error log. * 🔇 fix: Keep Cancelled Tool Calls on the Filtered Path and Out of Error Logs Addresses both findings from the Codex review of 48fded564a. P1 — the cancellation branch returned before `filteredToolOutputResult`, so with tool-output filtering configured an aborted call's error text reached the turn uninspected. Worse, `runSignal.aborted` says the run is over, not that this rejection was the cancellation: an unrelated failure racing the Stop took the same unfiltered exit. Cancellation now only selects the log level; filtering and the result shape are unchanged. P2 — `createMCPTool` logs its own error before wrapping and rethrowing, so every Stop during an MCP call still emitted an error-level MCP entry and could pollute operational alerts. That catch now recognizes the abort and logs at debug; the wrapped message still reaches the turn. Both are covered by tests that fail against the previous commit. * 🎯 fix: Require an Abort-Shaped Error and Spare Shared OAuth Flows Addresses both findings from the Codex review of b3c67082cd. An aborted run signal proves the turn is over, not that the rejection in hand was the cancellation — a permission, OAuth, or upstream failure can reject in the same tick a user presses Stop. Both quiet-log branches now require the error to look like an abort as well, so a real failure racing the Stop stays at error level and visible to operational alerts. `isAbortError` moves to `@librechat/api` and the copy in `abortMiddleware` is retired, keeping one implementation. Its spec pulls the real function through its partial package mock rather than asserting a stub. Forwarding the run signal also reached ActionService, where two of the three OAuth flows are keyed `userId:action_id` and so outlive the run that opened them: a second run for the same action joins the very same record, and the browser's OAuth callback reads its metadata to exchange the code. `monitorFlow` deletes the key when a waiter's signal aborts, so one Stop could strand a concurrent run and discard an authorization the user had already granted. Those two flows no longer take the signal; the run-scoped login flow, keyed by thread and run, still does. Every guard is covered by a test that fails when the guard is removed. * 🧷 fix: Detach the Stopped OAuth Waiter Instead of Dropping Its Signal Addresses the Codex review of d53ff170ab. Withholding the run signal from the shared Action OAuth flows protected concurrent runs and the browser callback, but left this invocation attached to the flow after the Stop. A callback landing late then resumed `_call` straight into `preparedExecutor.execute` — a consequential API request running after the user had already stopped the turn. Handing the signal back is not the answer either, since `monitorFlow` deletes the shared `userId:action_id` key on abort. `detachOnAbort` separates the two: the caller stops waiting the moment the signal aborts, while the shared flow runs on for whoever else needs it — another run, or the callback exchanging its code. Late settlement of the detached work is swallowed rather than surfacing as an unhandled rejection. Both shared flows now use it. The run-scoped login flow keeps the signal directly, as nothing outside its run observes it. * 🪪 fix: Keep an Action OAuth Abort an Abort Addresses two of the three findings from the Codex review of 70fc0782b1. Detaching the stopped waiter left the rejection to be misread on the way out. The refresh catch treated it as a failed refresh and called `requestLogin()`, emitting an OAuth prompt and opening pending authorization state for a turn that had already ended. `requestLogin` and the surrounding auth catch relabelled it `Failed to authenticate OAuth tool` / `Authentication failed`, and the outer catch handed that to `logAxiosError` — so an ordinary Stop produced two error-level entries and returned failure text as the tool's result. Each boundary now lets an abort through unchanged, and the outer catch logs it at debug and rethrows so it stays a cancellation end to end. Deferred: waiter-only cancellation in `FlowStateManager`, so a detached `monitorFlow` stops polling instead of running out the flow's TTL. That poller is bounded at three minutes and lives exactly as long as it does for a waiter that never left, so it changes no lifetime this branch introduced; giving `FlowStateManager` a non-destructive abort mode is its own change, shared with MCP and indexSync. * 🤫 fix: Classify the Abort at the MCPManager Boundary Too Addresses the Codex review of 9bcf1aa57e. `MCPManager.callTool` logs every rejection at error level before rethrowing to `createMCPTool`, so a user Stop still emitted an MCP error from the inner boundary even after the outer one learned to recognize it. The same signal-plus-abort-shape classification now applies here. The review also noted, correctly, that the existing test could not have caught this: it replaces `getMCPManager` wholesale, so it only ever exercised the outer logger. The new cases drive the real manager with a connection whose `client.request` rejects the way the SDK does once a request signal aborts, and cover both the cancellation and a genuine failure racing the Stop. * 🧹 chore: Restore Import Order in the Agents Tool Handler	2026-09-02 13:32:33 -04:00

Danny Avila	a3c2277c38	🚧 fix: Narrow Chat MCP Selections to What the Picker May Offer (#15478) ... * 🚧 fix: Narrow Chat MCP Selections to What the Picker May Offer The chat MCP picker offers a server only when the operator has not hidden it (`chatMenu: false`) and the user reaches it directly rather than through an agent (`consumeOnly`). Nothing enforced either condition on the request, so a stale client, a replayed body, or a hand-written one could name any server and get its tools — `consumeOnly` in particular is a permission the registry derives per user, so ignoring it let a user reach in plain chat a server they had only been granted through an agent. Narrow the picker's selection in the two ephemeral loaders, against the same predicate the client's `selectableServers` uses. The resolver is injected, so `packages/api` stays free of the registry and the loaders keep their existing `deps` shape. Provenance is why this lives in the loaders rather than at the tool-resolution chokepoint: only here is a server name known to have come from the picker. Servers a model spec pins are the operator's own choice and are added after the narrowing, so pinning a chat-hidden server to a spec keeps working. `chatMenu` only ever comes from the config tier, so the overlay settles it with no lookup at all. Lookups for the rest run concurrently and are cached per server and user. A name the registry cannot resolve — request-tier, declared on the body and never registered — is kept, as is one whose lookup fails: this narrows an already-authenticated selection and is not the authorization boundary. * 📝 docs: Say What chatMenu Now Bounds The schema still described `chatMenu` as dropdown visibility alone, which is misleading now that it also bars a server from the chat selection a request carries. Spell out both halves, and what it deliberately does not restrict: agents, and servers a model spec pins. * 🛡️ fix: Close Four Gaps in the Chat MCP Narrowing Dedupe before resolving. The selection is request-supplied and the loaders used to build a `Set` immediately; mapping the raw array first let one body repeat a name enough times to launch a resolver — registry, cache, and ACL reads, with no single-flight — per occurrence. Resolve names through the tool-loading aliases. A configured `private server` is addressable as `private_server` downstream, so an exact-key lookup let the normalized spelling walk past a `chatMenu: false` check and still load tools. Names are returned as sent; only the decision is canonicalized. Let the request overlay settle `chatMenu`. The config tier is where the flag lives and is what the picker itself was built from, so an overlay that re-enables a server now outranks the durable config the registry returns, which was silently dropping a valid selection. `consumeOnly` still comes from the registry. Narrow the request body, not just the loader's copy. `applyContextToAgent` reads `req.body.ephemeralAgent.mcp` directly and prefers it over the agent's tools, so a hidden server's `serverInstructions` reached the model context even after its tools were dropped. * 🧭 fix: Ask the Registry Which MCP Servers the Picker May Offer Three rounds of review found the same mistake in three disguises: this narrowing re-derived the registry's tier precedence instead of asking for it. A config entry was treated as authoritative over a user-DB or process-backed server of the same name; the alias map was built from config names only, so a DB server named `private_server` was misrouted to a config `private server`; and the overlay short-circuit ran before any of that could be consulted. Resolve the accessible set through `resolveAllMcpConfigs` instead — the same call behind `GET /api/mcp/servers`, so what the request may use and what the picker was offered come from one place and cannot drift. Precedence, cross-tier name collisions, and the config overlay are the registry's job again, and the selectability test is a single flag check over what it returns. The result is smaller: no overlay branch, no per-server lookups, one catalog read regardless of how long the selection is, and aliases built over the whole accessible set so an exact name always outranks another server's normalized form. Publish the servers actually in play back onto the request body, spec pins included. `applyContextToAgent` prefers that list over the agent's tools, so narrowing to the picker selection alone had started dropping a spec-pinned server's `serverInstructions` while suppressing a hidden one's.	2026-09-01 18:47:36 -04:00

Oliver Faust	5e49868f0a	🔑 fix: Decode Action OAuth Credentials After Decryption (#14698) ... * 🔑 fix: Decode Action OAuth Credentials After Decryption Action client credentials are URL-encoded before encryption, but the OAuth token exchange decrypted them with `decryptV2` alone, sending values like `abc%40domain.com` to the provider and causing 401s for secrets containing `@`, `+`, `=`, `/` or `:`. Decoding falls back to the raw decrypted value so legacy secrets stored before 299cabd6e (which contain an unescaped `%`) still work. Fixes #14636 * 🔑 fix: Share Action Credential Codec Between Read Paths The encode-before-encrypt convention had two readers with different behaviour. `ActionService.decryptSensitiveValue` decoded unconditionally, so a credential stored before encoding was introduced (299cabd6e, March 2025) containing a stray `%` threw `URIError` and failed every read of the action, not just the token exchange. Extract the pair into `packages/api/src/actions/crypto.ts` as the single implementation and consume it from both `ActionService` and the OAuth token exchange, so the two paths cannot drift again. Tests cover the codec against real crypto: reserved characters and literal percent escapes round-trip, pre-encoding values are returned unchanged, and a pre-encoding value with a stray `%` no longer throws. A version marker on newly encrypted values was prototyped and dropped: it changes the stored format for every action credential while fixing nothing, since values written by the encoding convention already decode correctly and pre-encoding values stay unmarked either way. --------- Co-authored-by: Danny Avila <danny@librechat.ai>	2026-09-01 18:42:28 -04:00

Danny Avila	8f6228095f	🖼️ fix: Stop Reporting a Failed Sandbox Image Read as an Unreadable Format (#15453) ... * 🖼️ fix: Stop Reporting a Failed Sandbox Image Read as an Unreadable Format `read_file` on a `/mnt/data` image collapsed every failure — rate limit, missing path, truncated transfer, transport error — into the binary-file hint, whose image branch reads as a permanent capability limit ("is an image file and cannot be read as text"). The model stopped retrying, and the operator had no way to tell which failure had actually occurred. The failure that surfaced it: the reader windows the bytes through `/exec` stdout, one call per window, against the Code API's per-user execution limiter (20 requests / 30s in the reference deployment). At a fixed 32KB window a 122KB chart cost 4 calls and a 1MB image cost 33 — more than a whole limiter window, so anything over ~640KB could never complete. A turn that generates several charts and reads them back exhausts the budget partway through and reports the 429s as unreadable images. - `handlers.ts`: failed reads name the real cause and the affordance that matches it — rate-limited waits and retries, a missing path lists the directory, a truncated transfer retries. The "cannot be read as text" phrasing is now reserved for bytes that are not a supported image. An image past the inline budget says to downscale and read the smaller copy rather than pointing at `bash_tool`, which cannot show an image. - `process.js`: the window is derived from the runner's stdout budget (48,960B vs 32,768B, so a 122KB chart is 3 calls and 1MB is 22), halves and re-reads the same offset when a runner truncates anyway (remembered per Code API, with the env remedy logged), waits out a rate limit it can afford instead of discarding the bytes already pulled, and stops at a 24-call ceiling so no read stalls a turn across limiter windows. - `utils/code.ts`: shared `getCodeApiRetryAfterMs` (header, then the `retry_after_seconds` body); `skillFiles.ts` drops its private copy. * ♻️ refactor: Move the Sandbox Image Reader Into TypeScript Addresses the review round on #15453. - P1: windowing, window sizing, the in-sandbox reader script, response parsing and byte assembly move to `packages/api/src/files/code/image.ts`, and the Code API rate-limit policy to `packages/api/src/utils/code.ts`. `process.js` keeps only the `/exec` transport it owns. Both new modules are tested against their real implementations (19 + 13 cases), including the round-trip ceiling, the changed-file guard and the shell-injection guard on the reader script. - P2: a configured stdout budget below the old 8KB window floor produced a window the runner could never emit, and narrowing was pinned to the same floor, so no retry could succeed. The window now aligns to the base64 group size instead, and the round-trip ceiling bounds what a small budget costs. - P2: `.env.example` documented a 32,768-byte default that no longer holds and never mentioned the stdout budget. It now describes `LIBRECHAT_CODE_SANDBOX_OUTPUT_MAX_SIZE` as the setting to tune, with the chunk override as the escape hatch. - P3: `process.spec.js` no longer reimplements the retry parser in its module mock. Behaviour is tested where it lives; the mock is a declared passthrough and the spec covers what the transport still owns — session forwarding, the profile header, parser hand-off and error logging. - P3: `getCodeApiRetryAfterMs` reads the response body through `in` narrowing rather than an `as` assertion. - P3: the window-sizing JSDoc no longer claims a multiple of 3 in the one case that is not — an explicit `LIBRECHAT_CODE_IMAGE_CHUNK_BYTES`. * 🎯 fix: Size Sandbox Image Reads to What the Limiter Can Deliver Addresses review round 2 on #15453. - Narrowing now halves the caller's own failing window instead of the shared learned value, and the learned value only moves down to the narrowest size any read needed. Reads run concurrently (one per tool call), so two reads failing at the same size were compounding into a window two steps smaller than the runner would have accepted, and persisting it for every later read. - Narrowing continues until a runner accepts a window or a floor below which no runner could serve an image at all. Two halvings stopped at 12,240 bytes — still ~16KB of base64 — so an 8-10KB stdout cap that was not configured up front stayed unreachable. - The round-trip ceiling is now one limiter window (20), and a read that cannot finish within it says so from the FIRST response rather than spending the whole budget rediscovering it: the first window reveals both the file size and what a call really delivers. A near-limit image no longer drains the turn's executions before failing, which is what made the wait budget look too small. - The round-trip message names the size this deployment can actually inline, so the model has a downscale target instead of a guess. - `python3: not found` from the sandbox reader was matching the generic "not found" in `isSandboxMissingFileError` and being reported as a missing image path, sending the model to `ls /mnt/data` while hiding a runner dependency. Image reads now classify only path-specific ENOENT forms as a missing file. * 📐 fix: Size a Truncated Read's Retry From the Cap It Revealed Addresses review round 3 on #15453. A ~1KB sandbox stdout cap is a real runner default, and the 1,536-byte narrowing floor sat above it: discovery stopped one step short and declared every image unreadable, even though small ones fit comfortably in the 576-byte window the configured path already derives. Narrowing now runs until no smaller window exists. It also no longer has to grope its way down: a truncated response emitted exactly as much as the runner allows, so its length measures the cap this deployment never declared, and the retry is derived from it directly — one round-trip instead of the eight blind halvings it takes to fall from ~49KB to ~1KB. Blind halving remains the fallback and bounds the result either way, so every retry is strictly smaller than the window that just failed.	2026-09-01 09:08:01 -04:00

Danny Avila	224512851a	🗂️ fix: Resolve Code Interpreter Destination Collisions (#15449) ... * 🗂️ fix: Resolve Code Interpreter Destination Collisions Codeapi mounts each `/exec` input at a destination derived from its `name` and rejects the whole request when two entries land on one. LibreChat never enforced that: `primeFiles` sent `name: file.filename` verbatim, and the graph seed deduped by `(storage_session_id, id)` — identity, not destination. Two conversation files sharing a filename therefore killed code execution for the rest of the conversation. The rejected request never reaches the sandbox, so no result comes back to collapse the pair, and every later turn re-primes both and fails identically. Only code-generated outputs are covered by the `(filename, conversationId, context, tenantId)` partial unique index; uploads carry `context: message_attachment`, so one conversation can hold several records sharing a filename — two uploads of `image.png`, or an upload whose name a later execution wrote back in place. `packages/api/src/files/code/destinations.ts` now owns the name → destination mapping for every contributor to an `/exec` file list, mirroring codeapi's conflict rule including directory-prefix conflicts: - `primeFiles` claims per pushed file, disambiguating with a `-2`, `-3` counter and echoing the resolved path into the tool context, so the model is told where each file actually mounts. Claim order comes from immutable `createdAt`, not `getFiles`'s `updatedAt` sort, which usage accounting and re-upload both bump — order-dependent destinations would silently repoint a path an earlier turn had already handed the model. Newest wins the bare name, matching `ToolNode.updateCodeSession` and giving an in-place rewrite precedence over the original it superseded. - `seedCodeFilesIntoSessions` drops a later file whose destination is already claimed. Renaming there would invent a path nothing told the model about, and a conflict at that layer means one logical file arrived twice under different storage pointers. Fixes #15443 * 🧹 chore: Tolerate Holes in the Destination Priority Sort `primeFiles` sorts the raw `getFiles` result before its own per-entry guard runs, so the comparator has to survive a null row rather than throw ahead of the loop that was already defending against one. Also tightens the tool-context assertion in the upload-vs-output case, which was passing on a trailing space rather than on the path. * 🔁 fix: Address Codex Review on Destination Assignment Four findings from the review of `b0f61d0`. **Identity-derived suffixes instead of a collision counter.** A counter is assigned from whatever is in the set, so a third file arriving under the literal name a displaced file had been given pushed that file along, and code the model wrote in an earlier turn would silently start reading the newcomer. The fallback now hashes the file's own `file_id`, so a displaced file keeps its destination for the life of the conversation and only the winner of the bare name can change. A trailing counter still guards a hash collision so the search terminates on any input. **Rank by last content write, not record creation.** `processCodeOutput` claims one row per `(filename, conversationId)` and rewrites it in place, so a repeatedly written output keeps its original `createdAt` while recording the latest writer in `metadata.sourceDispatchedAt`. Ranking on `createdAt` alone handed the bare path to an upload the output had since been rewritten over. Recency is now `max(sourceDispatchedAt, createdAt)` — still never `updatedAt`, which usage accounting bumps without any content changing. **Advertise a displaced generated output.** Generated files are left out of the tool context because the model already knows what it wrote — which stops being true once a newer same-named file takes the bare path and the output mounts somewhere the model has never seen. Displaced outputs are now listed with the name they were written as, and displaced uploads name their original too. **Rank conversation files above an agent's private ones.** Each agent claims destinations over its own candidate set — the conversation's files plus its own — so a private file taking a bare name from a shared file in one agent but not in another left two agents advertising different paths for the same file into one shared mount namespace. Shared files now rank first, so the majority that every agent sees resolves identically. The private-versus-private case still drops at the merge and is documented there; closing it needs one assignment across contributors, made before any agent renders its context. * 📌 test: Pin Alias Ownership on an In-Place Rewrite Codex round 2 flagged that the identity alias still falls back to a counter when the alias itself is literally claimed, so a displaced file can move after all. The mechanism is real and my JSDoc overstated the guarantee, which this corrects. The behaviour stays as it is. The realistic way a file arrives under another file's alias is the model rewriting the displaced file in place: it was told `<stem>-<hash>.ext`, wrote back to it, and `processCodeOutput` registered an output under that literal name. Keeping the alias with the newest holder is what makes the model's familiar path resolve to its own edit; reserving it against the newcomer would hand that path back to the bytes it replaced. The test pins that ordering so a later change cannot invert it silently.	2026-09-01 00:55:54 -04:00

Hitting the login rate limit during a social sign-in dropped the user on a blank page showing: {"message": "Too many login attempts, please try again after 5 minutes."} Mark those requests with markOAuthNavigation and have the two middlewares that can reject them answer with a redirect to the login page carrying an error code the client localizes.

Danny Avila	982a9a5141	🧴 fix: Strip LangChain URLs From Provider Errors (#15421) ... * 🧹 fix: Strip LangChain Attribution From User-Facing Provider Errors LangChain classifies provider failures by mutating `error.message` with a docs URL, and that message is forwarded verbatim into the error content part we persist, so users saw `docs.langchain.com/...` credited for a provider's own 429. The client only intercepted `MODEL_NOT_FOUND`, leaving every other code to render raw. Resolve the classification server-side instead: codes with localized copy become the typed payload the client already knows how to localize, and every other message keeps the provider's wording with the docs URL removed before it reaches the database. The untouched error still reaches the logs through `getSafeErrorMetadata`. The client keeps a code-driven lookup for messages persisted before this, and gains `com_error_model_rate_limit` alongside the existing not-found copy. The OpenAI-compatible and Responses controllers now share one provider-error helper rather than three copies of it, so the strip applies on those surfaces too. * 🛡️ fix: Harden Error Sanitization For Non-String Messages And Legacy Text Codex review follow-up. `stripLangChainTroubleshootingUrl` assumed a string, so an error-like object with a truthy non-string `message` threw `.replace is not a function` inside the error handler that was meant to report it — the template interpolation it replaced had coerced such values safely. It now coerces at the boundary, as does the code lookup. Legacy messages whose LangChain code has no localized copy still rendered the docs URL, which is exactly the historical case the client-side path exists to clean up. The rendered fallback is now stripped too. Both helpers move to `librechat-data-provider`, which is shared by the client and the backend, so one implementation serves both instead of a second regex drifting in the component.	2026-08-31 12:51:34 -04:00

Danny Avila	413906abc3	🖍️ fix: Honor Agent Image Detail Settings (#15407) ... * 🖼️ fix: Apply an Agent's Configured Image Detail The Agent Builder exposes an Image Detail slider and saves it to `model_parameters.imageDetail`, but nothing ever read it back: `encodeAndFormat` resolves the level from `req.body.imageDetail`, which the agents route never populates, so every image was encoded as `detail: "auto"`. Providers that reject `auto` — MiniMax's OpenAI-compatible API among them — fail every image upload through an agent, and the setting that would fix it has no effect. The root cause is a classification error rather than a missing argument. `extractLibreChatParams` splits LibreChat's own settings out of an agent's model parameters, and its key set is derived from the `librechat` group in `parameterSettings`. `imageDetail` sat in `baseDefinitions` instead, so it was neither extracted for LibreChat's use nor stripped from the options handed to the provider. It is now grouped with `resendFiles` and the other LibreChat-level parameters, which gives it the same path those already take: extracted during agent initialization, carried on the initialized agent, passed to the client, and read by `encodeAndFormat`. `AgentClient.getSaveOptions` already expected `options.imageDetail` — nothing had ever populated it. The request body still wins where it is set, so the classic endpoints keep resolving detail from conversation settings exactly as before. Fixes #15359 * 🔤 fix: Type Image Detail as Its Enum, Not a Bare String `TConversation.imageDetail` is the `ImageDetail` enum, so the extractor's return type and the initialized agent's field are now declared as that enum rather than widened to `string`, and the tests pass enum members instead of raw literals. Caught by CI's type check, which I had run before adding the tests and not after — jest compiles the specs through babel, so the suite stayed green over a type error.	2026-08-31 08:34:05 -04:00

Dustin Healy	8fcab7e44f	🔄 fix: Recover Missing MCP Marketplace Catalogs (#15323) ... * fix: recover missing MCP marketplace catalogs * fix: make MCP catalog recovery passive * test: type MCP catalog recovery fixtures * fix: bound and back off passive MCP catalog recovery Passive recovery runs inline on `GET /api/mcp/tools` and its results are request-local by design, so every list request re-dialed the same cold servers with the default connection timeout. Three limits keep that cost proportional to what recovery can actually recover: - Cap the discovery timeout at 5s instead of inheriting the connection default (`initTimeout ?? 30s`); a server configured to connect faster keeps its own shorter limit. - Skip a server the config tier already marked `inspectionFailed`, leaving it to that tier's retry window rather than re-dialing it per request. - Skip a server whose declared `customUserVars` are unset, matching the gate `reinitMCPServer` applies for issue #10969 — connecting without them fails auth, so the attempt is spent for nothing. Servers that still fail discovery enter a one-minute per-process cooldown, which is what stops an unreachable server from being re-dialed by every subsequent list request. A server that recovers clears its own entry, and expired entries are swept at most once per window so the map stays bounded. Skipped servers render exactly as they did before recovery existed: present in the catalog with an empty tool list. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Xr1Dabvdn1mzzyYgpJgU5B * fix: bound passive MCP recovery by deadline, key cooldowns by config Both follow-ups address the same mistake: recovery expressed its own request-level constraints in terms borrowed from other layers. `connectionTimeout` bounds one connection attempt, and `MCPConnectionFactory.discoverToolsInternal` spends it twice — once on the authenticated connection, then again in `attemptUnauthenticatedToolListing` — so capping it bounded no total this layer could reason about. Recovery now enforces its own wall-clock deadline per server with `withTimeout`, which holds however many attempts the factory makes; `connectionTimeout` is left to do only its own job, still honouring a shorter operator `initTimeout`. An attempt abandoned by the deadline disposes its own connection when it settles, and `Promise.race` keeps a handler on it, so a late rejection is not unhandled. A per-request budget now caps total recovery regardless of server count. A server is dialed only if the remaining budget can fund a full deadline; never dialing one is not evidence against it, so a skipped server records no cooldown and a later request reaches it once those ahead are cached or cooling down. Cooldown identity now includes the publication generation — the same effective-config identity the tool caches fence on — instead of just user and server name. Correcting a server's URL or transport keys a new entry, so the refetch the client issues on update is no longer skipped for up to a minute by the previous configuration's failure. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Xr1Dabvdn1mzzyYgpJgU5B * refactor: keep passive MCP recovery stateless and bounded by its own work Reverts the cooldown, request budget and deadline race added in 257d5cf and fc3e3c9, and keeps only the three stateless limits. The tool cache refuses unfenced writes (`tools.ts`), and a discovery connection owns no publication generation and is disposed, so a recovered catalog cannot be retained by design. Those commits responded by building a cache-shaped memory in front of it — per-process failure state, a scheduling budget, an identity, an eviction sweep — and each round of review found another way that hand-rolled cache differed from a real one: wrong identity for configuration, wrong identity for credentials, no fairness across requests, and a limiter slot released while its network operation was still running. None of that machinery was asked for; all of it was compensation for a result the architecture does not allow keeping. Recovery is now stateless. It skips only what configuration alone proves pointless — a server the config tier already marked `inspectionFailed`, and one whose declared `customUserVars` are unset — and bounds the work itself rather than racing it, so a limiter slot is held for exactly as long as its network operation runs and the concurrency limit of three is real. The attempt timeout is not a compromise: recovery exists for a server that is reachable and authorized but whose catalog cache expired, and such a server answers tools/list well inside 1.5s. Anything slower cannot be rescued here, so failing fast costs nothing. The factory spends that value per attempt, so a server's ceiling is it times the attempts made; the constant documents that rather than hiding it behind a number tuned to today's attempt count. Consequences that were bugs are now gone by construction: every cold server is attempted on every request, so none is starved by those ahead of it, and correcting a server's configuration or credentials takes effect on the next refetch instead of waiting out a stale cooldown. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Xr1Dabvdn1mzzyYgpJgU5B * fix: correct the inspection-failure skip and bound catalog fan-out Three fixes that belong to this layer; a fourth issue does not, and is described below. The `inspectionFailed` skip was too broad. `MCPServersInitializer` stores a YAML server that was unreachable at startup via `addServerStub`, which stamps `source: 'yaml'`, and only config-tier entries get the timed retry in `ensureSingleConfigServer`. Skipping every failed stub therefore hid a recoverable server from the marketplace permanently — the exact state this recovery exists to escape. It now defers only `source === 'config'`, matching what `reinitMCPServer` already does. Plugin auth is read only when some cold server actually declares `customUserVars`, and only for those servers. The common unauthenticated case no longer pays a MongoDB round trip whose result nothing can consume. Snapshot refreshes are now bounded by the same limiter as discovery. They are not local reads: both connection paths reach `fetchOrderedToolsSnapshot` and issue a real `tools/list`, so a cache reset across many servers previously burst unbounded outbound requests while discovery was capped at three. Not fixed here, because it cannot be: `connectionTimeout` does not bound discovery. It covers `connection.connect()` only, and `fetchToolsSnapshot` then applies its own `TOOLS_LIST_TIMEOUT_MS` (30s) to `tools/list`, so a server that connects fast and stalls while listing still holds its slot for that window. The factory also does not cancel a timed-out connect before starting the unauthenticated fallback. Bounding this end to end needs a deadline threaded through `MCPConnectionFactory` into both `connect()` and `fetchToolsSnapshot()`, which is a change to shared connection machinery rather than to this caller. The constant's comment now states what it does and does not bound instead of implying an end-to-end guarantee.

Danny Avila	fa913148fb	🔒 fix: Refresh MCP OBO Tokens From the Live OpenID Session (#15334) ... * 🧊 fix: Inline-refresh OpenID session tokens at MCP OBO call time Resolves the walk-away failure mode where MCP tool calls using OBO auth fail with "No valid OpenID access token is available for OBO exchange" after a user idles past their access-token lifetime. The strategy-time snapshot on `user.federatedTokens` could expire mid-stream before `resolveOboToken` ran, while `req.session.openidTokens` carried a still- valid (or refreshable) token that nothing read. - New OpenIDSessionRefresh service: per-user single-flighted closure that reads `req.session.openidTokens` at OBO time and inline-refreshes via `openid-client.refreshTokenGrant` when expired (30s skew), persisting via `req.session.save()`. No cookie writes (headers already flushed). - `resolveOboToken` gains a required UpstreamTokenProvider parameter (typed as `() => Promise<OIDCTokens | null>`, reusing the shared shape from @librechat/data-schemas). Compile-time guarantee that every call site is updated. - New `session_refresh_failed` OboTokenResolutionReason distinguishes "session expired and IdP rejected refresh" from "no upstream token ever existed." - `req` threaded through createMCPTool/createMCPTools/createToolInstance to construct the closure with captured request, plus fail-closed guards in MCPConnectionFactory.getOboTokens and MCPManager.callTool when the closure isn't plumbed. - Startup warning in MCPServersInitializer when OBO is configured but OPENID_REUSE_TOKENS is unset (the strategy populating user.federatedTokens is only registered under reuse, so OBO would fail every call without it). Tests: 16 new in OpenIDSessionRefresh.spec.js; obo.spec.ts extended for the new param + error reason; wiring smoke tests in MCPManager, MCPConnectionFactory, MCPServersInitializer, and MCP.spec.js. * 🛡️ fix: Harden OBO inline-refresh against token type and session edge cases - Token-preference asymmetry: live-token reuse and expires_at derivation now strictly gate on the access_token, not the id_token. Added a required `tokenPreference` parameter on isLiveSessionTokenStillValid, buildOIDCTokensFromSession, and createOpenIDSessionTokenProvider so every call site is explicit. Dropped the bogus id_token-exp fallback in performIdpRefresh — id_token TTL is governed by IdP session policy and would mark a short-lived access_token reusable past its real lifetime. - Missing req in /reinitialize route: the manual reconnect endpoint now forwards req into reinitMCPServer, so OBO servers can build a session-aware upstream-token closure instead of failing with missing_upstream_token. - Single-flight key collisions: composed key as tenantId:openidIssuer:openidId:sessionId via getSingleFlightKey. Concurrent calls in the same session still coalesce; separate sessions never share an in-flight refresh, preventing refresh-token rotation from breaking sibling sessions and preventing cross-tenant token crossover when distinct users share an IdP sub. - Opaque access token reuse): persist accessTokenExpiresAt (unix seconds, from tokenset.expires_in) on each refresh AND on initial login / SPA refresh in setOpenIDAuthTokens. New getAccessTokenExp helper falls back to it when the access token isn't a JWT, avoiding redundant inline refreshes for Microsoft Graph and Auth0 default audiences. - Log hygiene: the single-flight key (containing sessionId, openidId, openidIssuer, tenantId) is now SHA-256-hashed in the "Joining in-flight refresh" debug log. Preserves cross-line correlation via a 12-char prefix without leaking credential or PII material. Documented req.session.openidTokens shape contract via JSDoc typedef so the new accessTokenExpiresAt field has a discoverable home alongside the existing accessToken/idToken/refreshToken/expiresAt/lastRefreshedAt. Tests: OpenIDSessionRefresh.spec.js up to 30 passing (added coverage for opaque-token reuse, JWT-access-token-exp fallback, no-id_token-fallback regression, cross-session no-coalesce, persistence on refresh, and a guard against stale accessTokenExpiresAt carryover). AuthService.spec.js adds two cases covering accessTokenExpiresAt persistence on login. mcp.spec.js (route) gains a regression test asserting req flows into reinitMCPServer. * 🔍 fix: Detect OBO-only MCP admin config overrides Admin Config overlays for YAML-defined MCP servers compare only ADMIN_CONFIGURABLE_FIELDS to decide whether to lazy-init a config-tier override. The OBO config field was added after that fingerprint list, so an override that only added or changed `obo` was treated as unchanged YAML and skipped. Include `obo` in the admin-configurable field list and add a regression test for an OBO-only override. * 🔊 fix: Mock MCP OAuth timeout in SDK integration test MCPConnectionFactory.attemptToConnect reads mcpConfig.OAUTH_HANDLING_TIMEOUT when building the OAuth connection timeout. The SDK OAuth integration test mocked mcpConfig without that field, which made the timeout calculation produce NaN and caused the test to fail before the OAuth refresh/start path completed. Add OAUTH_HANDLING_TIMEOUT to the test mock. * ♻️ refactor: Pass OBO upstream-token closure into MCP instead of req Build the OpenID upstream-token provider at the request boundary and thread only the closure through MCP handling, so the MCP service layer no longer receives the raw Express request. The closure still reads/refreshes the live session at tool-call time, preserving the walk-away recovery. - Drop `req`/`capturedReq` from createMCPTools, createMCPTool, reconnectServer, createToolInstance, and reinitMCPServer; forward `upstreamTokenProvider` instead. Closure is constructed in loadTools, loadToolDefinitionsWrapper, and the reinitialize route, where req/res are in scope. - OBO: fall back to user.federatedTokens when the provider yields no live session, so OIDC remote-agent calls (verified bearer, no session) still work. - Inline refresh: mirror a rotated refresh token to the refreshToken cookie via a shared setRefreshTokenCookie helper, guarded by !res.headersSent (no-op on the streaming path; session copy stays authoritative). - Single-flight: hydrate a joining request's own session from the resolved tokens so a later OBO call doesn't replay a rotated-away refresh token. Addresses owner feedback and three review findings. * 🔒 fix: Recover OIDC refresh-token rotation after SSE OBO refresh When an inline OBO refresh rotates the OpenID refresh token after SSE headers have already been sent, the browser refreshToken cookie cannot be updated. Store a short-lived encrypted bridge from the stale cookie token to the rotated token so /api/auth/refresh can recover after express-session loss. Use the signed openid_user_id cookie to load user context for bridge validation, retry only on invalid_grant, and delete the bridge only after the bridged refresh succeeds. * 🔨 fix: hydrate joined OIDC refresh sessions with stable refresh tokens Update single-flight OIDC refresh joiners whenever refreshed access token state changes, even if the IdP keeps the refresh token unchanged. This prevents joined requests from retaining stale accessToken or accessTokenExpiresAt values and redundantly refreshing later in the same run. * 🌉 Persist OIDC refresh-token recovery bridges in MongoDB Store SSE OBO refresh-token recovery bridges in MongoDB instead of process-local memory so /api/auth/refresh can recover after worker restarts or cross-worker routing. Derive bridge expiry from REFRESH_TOKEN_EXPIRY so the recovery window matches the stale refreshToken cookie it repairs, and delete bridges after successful recovery. * 🤝 Coordinate OIDC inline refreshes across workers Add a short-lived Mongo-backed refresh-flight record so concurrent OBO refreshes for the same OpenID session do not redeem the same rotating refresh token on different workers. The winning worker performs the IdP refresh and stores an encrypted result; joiners wait for that result, hydrate their request session, and return without calling the IdP. * ⚓ Keep OpenID marker cookies aligned on inline refresh Refresh token_provider and openid_user_id with the same expiry as the rotated refreshToken cookie when an inline OBO refresh can still write headers. Share the marker-cookie writer with the normal OpenID auth refresh path so the fallback /api/auth/refresh branch continues to recognize valid OpenID refresh tokens after session expiry. * 🔑 fix: include refresh token in OIDC local refresh flight key Key the process-local OIDC refresh coalescing by the current session refresh token, matching the Mongo-backed flight key. This prevents a request with a newly rotated token from joining an older pending refresh and inheriting its failure/result. * 🌉 fix: store OIDC refresh bridge without cookie response Treat missing or non-cookie responses like headers-sent streaming responses during inline OIDC refresh. When the IdP rotates the refresh token and cookies cannot be written, persist a recovery bridge so a later /auth/refresh can recover after session expiry. * 🫙 fix: preserve stale OIDC cookie bridge key Track the refresh token last written to the browser cookie separately from the current session refresh token. When inline OIDC refreshes rotate tokens without a writable response, keep bridging from the browser-stale token directly to the latest session token. * 🙌 fix: keep OIDC bridge recovery success on cleanup failure Make refresh-token bridge cleanup best-effort after a bridged OIDC refresh succeeds. A transient delete failure now logs a warning but does not convert the already-refreshed session and cookies into a 403 response. * 📦 test: Exclude RefreshTokenBridge from tenant-isolation coverage Add RefreshTokenBridge to the tenant-isolation coverage allowlist because refresh bridge lookups run during unauthenticated OpenID refresh recovery. The controller first recovers user context from the signed OpenID marker cookie, then the bridge methods apply explicit user and tenant filters. Ambient tenant isolation would bind this recovery path to request-local tenant context that is not available at the point the stale cookie is being resolved * ⚡ Fix OpenID refresh flight retry and marker hydration Allow failed OpenID refresh flights to be reclaimed immediately instead of pinning transient errors. Preserve the browser refresh-token marker when joined refreshes hydrate session tokens from a shared flight result. Stabilize AuthService tests by isolating mocked module imports from prior suites. * 🛠️ fix: centralize OBO identity scoping Add shared auth identity helpers for app user ids, OpenID subjects, tenant ids, and normalized OpenID issuers. Thread a non-placeholder-visible OBO identity context from the real request user through MCP connection, tool-call, reinit, and refresh paths. Keep tenantId and openidIssuer out of createSafeUser so MCP user placeholders do not expose those fields. Scope OBO token cache and in-flight exchange keys by tenant, issuer, OpenID subject, scopes, and a SHA-256 hash of the upstream assertion. This prevents cross-tenant/cross-issuer collisions and avoids reusing tokens minted from stale rotated assertions. Use the shared identity helpers for OpenID refresh-flight keys and refresh-token bridge recovery records so related OBO refresh paths share the same identity normalization rules. The helper is intended for auth-boundary and credential-cache code, not as a blanket replacement for ordinary app user id ownership checks. * 🛠️ fix: preserve OIDC refresh-token sync on save failures Sync OpenID refresh-token cookie/bridge state before persisting the session so a transient session-store failure cannot lose an IdP-rotated refresh token. Also trigger sync when the session refresh token differs from the browser refresh-token marker, not only when the current grant rotates the token. This lets later writable refreshes repair stale browser cookies left behind by SSE refreshes. Route refresh bridge identity through the shared identity helper with the threaded OBO identity context, falling back to request/user context when needed. Add regression coverage for session-save failures, stale browser cookie repair, non-writable bridge storage, and shared-helper identity fallback. * 🛠️ fix: keep OIDC refresh bridge during recovery grace After successful bridged refresh recovery, re-store the stale-cookie bridge with a short grace TTL instead of deleting it immediately. This lets parallel /api/auth/refresh requests that already sent the stale browser cookie recover before they can observe the first response's Set-Cookie. Retarget the bridge to the refresh token returned by the bridged retry so B-to-C refresh-token rotation remains recoverable. The grace TTL is parsed with math() and defaults to 60s, which shrinks the replay window from the original REFRESH_TOKEN_EXPIRY bridge lifetime to the short recovery grace period. Remove the now-unused explicit bridge delete path from the service and data-schemas method surface. Add regression coverage for grace re-store, identity symmetry, retry failure behavior, and same-key upsert replacement. * 🛠️ fix: fail closed on OBO MCP user identity mismatch Add an OBO-specific guard before MCP tool execution that requires the effective invocation user and captured request user to both have ids and to match. This prevents OBO tool calls from falling back to a separate configurable.user_id identity after request-bound OBO context has already been captured. Keep the existing user id fallback behavior for non-OBO MCP calls. Tests cover mismatched OBO users, missing user ids, and the matching-user path ignoring a conflicting configurable.user_id. * 🛠️ fix: Guard OpenID bridge retry user identity Extract the shared OpenID refresh/user-resolution flow in AuthController so the normal refresh path and bridge-recovery retry use the same grant, claims, issuer, user lookup, and diagnostic logging code. Preserve the existing path-specific behavior: the normal path still owns migration updates and 401 login redirects, while the bridge retry still falls through to the existing 403 invalid-token response. Add a bridge-recovery guard that rejects retry results whose resolved user id differs from the signed openid_user_id cookie before issuing tokens or re-storing the grace bridge. Cover both the successful matching-user recovery and the mismatched-user rejection. * 🛠️ fix: type-safety polish on OBO data layer Replace refresh token bridge query/update Record<string, unknown> usage with typed Mongoose FilterQuery and UpdateQuery definitions. Harden OpenID marker cookie JWT expiry handling by converting refresh expiry milliseconds to integer seconds and rejecting invalid or non-positive durations. Add focused CSRF tests for fractional refresh expiry values and invalid expiry configuration. * 🛠️ fix: Bind OpenID session tokens to authenticated identity Stamp OpenID session token state with the LibreChat user id, OpenID subject, tenant id, and normalized issuer when tokens are stored. Fail closed before OBO inline token reuse/refresh when the session token identity does not match the current authenticated identity, preventing a stale or mixed Express session from supplying another user's upstream assertion. Also validate the normal /api/auth/refresh session-token reuse shortcut against the signed marker-cookie user before returning cached session tokens. Note: sessions created before this change carry no identity stamp and are treated as a mismatch. This is self-healing — the reuse path forces a full IdP refresh (which re-stamps the session) and the OBO path throws, surfacing as a one-time re-authentication for active OBO users at deploy time. The session re-stamps within one session lifetime (SESSION_EXPIRY, default 15 min). * 🛠️ fix: Recover OpenID refresh token drift Prefer the browser refresh-token cookie when it differs from the server-side OpenID session state, and force a real IdP refresh in that case instead of reusing stale session tokens. Store a short-lived refresh-token bridge when inline OBO refresh writes a rotated browser cookie but session persistence fails, so follow-up refreshes can still recover from the old token. Keep the bridge grace TTL centralized in RefreshTokenBridge so both recovery paths use the same env-backed value. Note: drift is measured against the last-synced browserRefreshToken marker, so the SSE path (intentionally stale cookie, authoritative session) does not false-positive. Sessions predating the marker have no browserRefreshToken; for those, drift falls back to comparing the cookie against the session refresh token and prefers the cookie on difference. This is the same self-healing pre-change-session window as the identity binding fix and re-syncs within one session lifetime. Tests cover cookie/session drift selection, reusable-session bypass on drift, bridge storage after session-save failure, and the shared bridge constant wiring. * 🛠️ fix: Harden OBO token caching and expiry handling Reject malformed OBO grant responses before writing them to the exchanged-token cache so a missing access_token cannot poison the cache. Store absolute expires_at values with cached OBO tokens and ignore legacy cache entries without usable expiry metadata. This keeps cached-token freshness based on the token’s real remaining lifetime instead of reusing the original relative expires_in on cache hits. Move OBO expiry normalization and skew helpers into packages/api and use them from both the JS exchange service and the TS MCP resolver. Apply a 30-second safety margin with a one- second floor for short-lived tokens, covered by direct helper tests and caller-level regression tests. Tests: - packages/api: npm run build - packages/api: npx jest src/mcp/oauth/expiry.spec.ts src/mcp/oauth/obo.spec.ts - api: npx jest server/services/OboTokenService.spec.js * 🛠️ fix: Harden OBO refresh-token bridge lookup and indexing Reuse getValidOpenIDReuseUserId for the bridge-recovery user lookup in refreshController instead of re-verifying openid_user_id inline. The shared helper enforces the JWT_REFRESH_SECRET presence check and a strict typeof payload.id === 'string' guard, rejecting tokens whose id claim is present but not a string (e.g. a numeric id) that the inline check accepted. Fail closed on issuer mismatch in getRefreshTokenBridge. Both the stored and the expected issuer are now normalized and compared for equality, so a bridge is recovered only when both sides agree (both absent, or both present and equal after normalization). Previously the check was skipped whenever the stored issuer was absent, allowing recovery across mismatched issuer context. Drop the unused {oldRefreshTokenHash, userId, tenantId, openidIssuer} index and the openidIssuer field on RefreshTokenBridgeQuery. The data-layer filter only queries the 3-field {oldRefreshTokenHash, userId, tenantId} index; the issuer is verified in application code, not the query. Hoist the repeated model accessor into getRefreshTokenBridgeModel. Note: issuer is now load-bearing for recovery. A bridge stored with an issuer recovers only when the lookup supplies a matching issuer; the recovery lookup reads user.openidIssuer via AUTH_REFRESH_USER_PROJECTION (an exclusion projection that retains the field). If a user's persisted openidIssuer is empty while the stored bridge has one, recovery fails closed (falls through to normal re-authentication) until the bridge TTLs out — no security regression. Tests cover invalid signed-cookie payloads bypassing the bridge, both asymmetric issuer-presence cases, issuer normalization before comparison, and an index-alignment assertion guarding against re-adding the dropped index. * 🛠️ fix: Degrade OBO discovery on token resolution failures Catch expected OboTokenResolutionError failures during MCP tool discovery and fall back to unauthenticated tool listing instead of aborting discovery. This keeps discovery aligned with the existing unauthenticated listing behavior while preserving unexpected errors as real failures. Also correct OBO tool-call freshness comment and tighten the OBO trust-check permissions type to the existing role permission shape. Tests: - npx jest src/mcp/__tests__/MCPConnectionFactory.test.ts --runInBand --coverage=false - npx jest src/mcp/oauth/obo.spec.ts --runInBand --coverage=false * 🛠️ fix: tighten OBO tool-call errors, bridge logging, and flight typing Move resolveToolCallUserId inside the tool-call try/catch so an OBO identity mismatch surfaces with serverName/toolName context and the standard tool-call-failed message instead of an opaque bare Error. Raise the refresh-token bridge lookup failure log from debug to warn so transient infrastructure failures on the unauthenticated /api/auth/refresh path are observable, and guard the message access against non-Error values. Replace the unknown+cast in isDuplicateKeyError with a hasErrorCode type predicate so the duplicate-key check reads error.code without an assertion. Preserve real math/isEnabled in the MCPConnectionFactory test mock (mock only processMCPEnv) so mcpConfig timeouts no longer resolve to NaN, fixing the TimeoutNaNWarning that masked slow OAuth retry behavior. * 🧪 fix: Restore the Flight Uniqueness Index and Buffer the Graph Cache TTL Two CI failures on the merge, both in suites this environment cannot run (their MongoDB binary download is blocked). `GraphApiService.spec.js` still asserted the unbuffered TTL. Graph tokens route through the same `getTokenCacheTtlMs` as the OBO and openidStrategy caches, so the entry now expires 30s before the credential does. `openidRefreshFlight.spec.ts` dropped the database between tests, which takes the indexes with it, and Mongoose builds them only once when the model is compiled. Whether the unique `key` index survived into a test was a race with that one-time build. Without it a second `create` inserts instead of raising a duplicate-key error, so every worker believes it won the flight — the mutual exclusion the file exists to prove. Indexes are now rebuilt after each drop, which also makes the reclaim and complete cases reach those paths for the right reason. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SxKWxwqxAGckYpRsYTqx3F * fix: address OBO review findings * 🔐 fix: Install Bridge Indexes and Carry OBO Through Assistant Recovery Two findings from the Codex pass on d08c82f0d. The refresh-token bridge relied on Mongoose auto-indexing for both of its indexes, and `MONGO_AUTO_INDEX=false` is a supported deployment setting. A bridge holds an encrypted refresh token and the TTL index is the only thing that ever deletes one, so under that setting they would accumulate for the life of the collection while concurrent upserts lost the compound uniqueness the filter assumes. Installed before the first write, matching the flight methods and the session and schedule methods before them. `recoverServerTools`, the assistant create/update path that reruns `reinitMCPServer` when a referenced server's catalog and connection snapshot are both missing, was the last reinit site not carrying the upstream-token closure. For an OBO server the factory rejects the connection outright, so the assistant write failed with unavailable MCP definitions. It now builds the provider at that request boundary like the other entry points; assistant writes have no `res`, so a rotation there falls back to the recovery bridge. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SxKWxwqxAGckYpRsYTqx3F * fix: harden OBO refresh coordination * ⏳ fix: Keep Elapsed Expiries Elapsed and Revoke the Superseded Session Two of the five findings from the Codex pass on fcdc15885 — the two that are defects in code this branch introduced rather than design questions about the bridge. `getSkewedTokenExpiresAtMs` floored every result at a second in the future, including an expiry the provider had already declared elapsed. An exchange answering `expires_in: 0` or a past `expires_at` was handed to the MCP connection stamped valid for another second, which only moves the failure downstream. The floor now applies to a lifetime that is still live, which is what it was for; an elapsed one stays elapsed so the caller rejects it. Same for the cache TTL, which falls back to the elapsed-credential floor. Bridge recovery left the stale token's durable Session behind. Only the token it recovered through was passed as `existingRefreshToken`, so that one's session was replaced while the token the browser actually presented kept its record until its original expiry. That record, with the marker cookie still bound to it, is what authorizes local image access for OpenID users — so a copy of the stale cookie outlived the rotation it had lost. Revoked explicitly on successful recovery.

That also makes the stale token the fallback the installed session and the refresh cookie use when a tokenset carries no `refresh_token` of its own, which holds only while the recovery grant rotates. An IdP that answers that grant without rotating sends the browser back to the very token the bridge exists to retire: `storeOpenIDSession` installs and deletes the same stale record in one call, and the cookie is rewritten to a token the IdP already rejected — a sign-out on the next refresh. The grace bridge one line above already guards this with `|| bridgedRefreshToken`; the resolved tokenset now does the same, so leader and followers alike publish the recovered token.

It is rejected at the exchange now, where the reason is known, and retryably — the exchange itself worked, so a fresh grant can succeed. Completes the elapsed-expiry change in cb26a6f7d, which made the stamp honest without giving anyone a reason to look at it.

Nothing asserted that, so removing the inner catch left every suite green while callers began receiving the cleanup error instead. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SxKWxwqxAGckYpRsYTqx3F * fix: compensate OpenID bridges only on proven ownership loss The post-write lease assertion deletes the bridge it just published when it throws, but it threw for two different reasons: a coordination record that is no longer ours, and a coordination read that simply failed. Treating the second as the first destroys the only mapping from the token the browser still holds to the one the IdP already rotated to, so a transient Mongo error on the headers-already-sent path signed the user out. Tag the ownership error where the lease raises it and compensate only for that, preserving the bridge whenever ownership is merely undetermined. A preserved bridge stays behind the logout revocation fence, so the safe default costs nothing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SxKWxwqxAGckYpRsYTqx3F * fix: reject spent OpenID refresh results Two ways a refresh could report success while handing back a credential nothing can use. An inline refresh carries the previous id_token forward when the IdP omits one on rotation, so tokenset.id_token is not necessarily freshly issued. setOpenIDAuthTokens applied its freshness guard only to the session copy and took tokenset.id_token unconditionally, so /refresh returned an expired bearer even though the grant produced a usable access token. Skip it only when it is provably expired: an id_token whose expiry cannot be read stays preferred, since access_token may be opaque or scoped to another audience. normalizeExpiresIn preserves a zero or negative lifetime rather than discarding it, so a grant declaring an already-spent access token still published, rotating the refresh token and returning a token every freshness check rejects. Each OBO call then repeated the grant. Reject an elapsed lifetime before publishing; an unknown lifetime still publishes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SxKWxwqxAGckYpRsYTqx3F * fix: harden OpenID refresh publication * fix: keep identity and results intact through OpenID refresh cleanup Two follow-ons from the last round's fixes. Stripping an expired carried-forward id_token from the refresh result removed the only identity material a rotation without id_token leaves behind. The result is rebuilt by buildOIDCTokensFromSession, so it carries no provider claims() either, and getTokenClaims accepts only those two — bridge recovery failed with "no usable identity claims" before setOpenIDAuthTokens could hand back the fresh access token. The stripped token now travels in a non-enumerable marker, alongside the existing browser and predecessor markers, which identity resolution reads and the authentication response never sees. The lease drained a pending renewal by awaiting it in finally, so a transient coordination failure there threw from finally and replaced the operation's result. The refresh had already settled and published, so the caller saw a failure on credentials that had rotated. Proven ownership loss is recorded on ownershipLost and checked before the return, so the drain has nothing to add but noise; it now absorbs and logs.

Danny Avila	01f5391ee3	🕰️ fix: Guard expires_in So a Token Response Cannot Outlive Its Credential (#15321) ... * 🕰️ fix: Guard `expires_in` So a Token Response Cannot Outlive Its Credential RFC 6749 §5.1 makes `expires_in` only RECOMMENDED, so a token response may legally omit it. Four sites derived a lifetime from the raw field, where `undefined * 1000` is `NaN`. `NaN` is not a short TTL, it is no TTL. `@keyv/redis` writes the key without `PX` because `NaN` is falsy, so the entry is stored in Redis with no expiration at all; the in-memory backend embeds `expires: NaN` and every check compares with `>`, always false against `NaN`. The namespace default does not stand in either, since Keyv applies it with `??=` and `NaN` is neither `null` nor `undefined`. The exchanged access token was therefore cached permanently at `openidStrategy.js` and `GraphApiService.js`, and once it genuinely expired the poisoned entry kept being served with no path to eviction. The same omission is sharper in `ActionService.js`, where `new Date(NaN).toISOString()` throws `RangeError: Invalid time value`. Both call sites are inside a `try`, so the failure surfaces as a generic "Failed to authenticate OAuth tool" that names nothing, and the refresh site falls through to `requestLogin()` on every attempt, looping with no exit. The rule had six hand-written homes and three of them were wrong, so it now has one. A new `packages/api/src/oauth/expiry.ts` normalizes `expires_in` to a positive finite number of seconds or nothing, and exposes the two shapes callers actually need: a cache TTL that falls back rather than returning `NaN`, and an absolute expiry that is absent rather than Invalid. The four unguarded sites adopt it, and the two ad-hoc guards in `openidStrategy.js` and `OboTokenService.js` are consolidated onto it. `createHandleOAuthToken` is folded in as well. Its guard already handled `null` and unparseable strings but admitted `NaN`, since `typeof NaN === 'number'` satisfied its first branch. The `mcp/oauth` sites are deliberately left alone: `tokens.ts` guards on truthiness and carries richer logic that reads a JWT access token's own expiry when the response omits one, and the file is being reworked in #13901. Closes #15318 Closes #15319 * 🕰️ fix: Address `expires_in` Guard Review Round 1 Preserve an explicitly elapsed lifetime instead of collapsing it into "unknown". `expires_in: 0` is the provider stating the credential is already dead, which is information; treating it as absent handed it the one-hour fallback in `createHandleOAuthToken` and dropped the expiry entirely in `ActionService`, so a credential declared expired could be used and retained for up to an hour. Both sites preserved that value before this branch, so the collapse was a regression introduced here. `normalizeExpiresIn` now returns any finite number, positive or not, and reports `undefined` only for a lifetime that is genuinely unusable. `getTokenExpiresAt` therefore yields a past timestamp for an elapsed lifetime, so callers refresh rather than guess. Cache TTLs cannot pass such a value through raw: Keyv reads a TTL of exactly `0` as "no expiry", turning a dead credential into the immortal entry this module exists to prevent. `getTokenCacheTtlMs` floors an elapsed lifetime at one millisecond, which expires immediately without ever writing an entry that outlives its credential. Parse numeric strings with `Number` rather than `parseInt`, which truncates a complete value such as `"3.6e3"` to `3` and would expire an hour-long credential after three seconds, re-exchanging against the identity provider on every request. An empty or blank string is rejected rather than read as zero, since `Number('')` is `0`. * 🕰️ fix: Bound `expires_in` to Lifetimes a Date Can Represent Parsing the complete numeric string last round made an overflow reachable that `parseInt` had been masking. `parseInt('1e13', 10)` was `1`; `Number('1e13')` is `1e13`, and `1e13` seconds is 1e16 ms, past the ECMAScript time value range of ±8.64e15. Every derived timestamp was therefore an Invalid Date whose `toISOString()` throws `RangeError: Invalid time value` — the exact failure this branch exists to remove, reintroduced by its own fix. The token model derives the same way at `packages/data-schemas/src/methods/token.ts:19`, so storage and authentication would fail with it. A lifetime is now reported as unusable unless it can still produce a valid `Date`. The bound is the time value range halved, leaving room for the `Date.now()` every derived timestamp adds. At roughly 137,000 years it rejects nothing a provider could mean: a one-year refresh token and even a hundred-year lifetime still pass through untouched, while `1e13`, `Number.MAX_SAFE_INTEGER` and `1e300` take the caller's fallback instead of poisoning a timestamp. The invariant tests now carry the overflow shapes rather than a fixed list of small ones, since a guard that only sees the inputs its author imagined is how the previous round's regression got in.	2026-08-28 10:47:09 -04:00
