Danny Avila	68fc46a055	🪢 feat: Resume Bound Event Actors from Checkpoint Forks (#15227) ... * feat: resume event actors from checkpoint forks * fix: fence event actor checkpoint uncertainty * fix: satisfy event actor type contracts * fix: make actor reconciliation recoverable * fix: preserve event actor lifecycle transitions * fix: fence event actor lifecycle outcomes * fix: enforce event actor lifecycle ownership * fix: retain event actor settlement proof * 🔒 fix: Retain Event Actor Receipts Through Repair and Bound Their Journal Repair and compensation deleted the reconciliation row they resolved, which was the only durable proof that the invocation had already applied an external action. A delayed duplicate owner could then reacquire the same invocation id and repeat that action. Both resolutions now retire their receipt to `settled` and record how it settled, so the same-id tombstone survives; `history_repaired` and `action_compensated` still force a cold rebuild. Compensation undoes the effect without re-authorizing the delivery, so a legitimate retry must arrive under a new invocation id. A retried repair converges on its own receipt. Bound the journal so a long-lived actor cannot grow its conversation document without limit: a new fence is admitted only when no active lifecycle row exists, so a capped push can evict nothing but the oldest settled receipts. Stop shipping the unbounded source payload on every bound-child continuation. It rode the delivery body regardless of the feature flag while the sibling `fire` body deliberately sends event identity alone, so a large webhook payload could push a previously working delivery past the chat route's body limit. The actor binds an invocation from identity and never builds the prompt from it. Blank the positional token map on warm continuations. It is derived from the full DB history, while a warm run executes on checkpoint-restored state, so its indices address different messages and the pruner never recounts them — misattributing cached counts to the wrong messages in both directions. Keep the replaced-claim exit on its cleanup path when preserving reconciliation fails: the committing CAS already left a blocking row, so the failed status upgrade costs provenance, not safety. * 🧪 test: Pin the Warm Continuation's Map/Summary Asymmetry Give the warm-continuation client test a populated token map and a real cross-run summary so its assertions bite: the positional map must arrive blank (checkpoint-restored state no longer matches DB-derived indices, and the pruner never recounts a populated entry) while `initialSummary` must pass through unchanged — it rides the system tail and summarizes pre-boundary turns that were excluded from the very history the committed checkpoint was built from, so blanking it would silently drop context no warm run can recover. * ⚖️ fix: Honor Compensation in Settlement and Age-Bound the Receipt Journal A compensated receipt still tombstones its invocation id, but its external effect was explicitly undone — the terminal handler nonetheless replayed every settled lifecycle's stored action as authoritative and settled the public outcome as applied, telling an action-aware source the operation stands and suppressing the new-invocation retry compensation requires. The handler now settles a compensated invocation as failed with an explicit compensation error, overriding even fresh applied run evidence from a replayed generation; verified and repaired receipts continue to replay applied. Receipt eviction is now primarily age-based: a stale same-id owner is bounded by time, not by how many newer invocations settle, so the previous count-only slice let a high-rate actor evict a tombstone while its delayed duplicate owner could still wake and repeat the action. Admission prunes only settled receipts older than a retention window that dwarfs every generation, job, and delivery-retry lifetime, and the count cap is demoted to a raised document-size backstop. * 🔀 fix: Serialize Compensation Against Settlement and Never Evict Live Receipts The terminal handler read its lifecycle snapshot, verified history, and then settled the public outcome — so a compensation resolving the same receipt during that window lost: the handler settled applied from its stale snapshot and no retry could ever change the replay-identity-locked outcome. The receipt's status CAS is now the serialization point: verification resolves the receipt BEFORE settling, whichever transition wins determines the public outcome, and a crash between resolve and settle converges through the retained receipt's replay. The verified-replay probe requires the receipt's own resolution, so a compensated receipt can never satisfy a verification retry. This inverts the settle-before-receipt ordering deliberately: that ordering guarded proof that resolution used to delete, and the receipt now retains its full action proof through resolution. The document-size cap is no longer an eviction quota. A receipt inside its retention window is never discarded: when the journal holds a full cap of unexpired receipts, new invocations are refused fail-closed until receipts age out, making duplicate protection and document integrity simultaneous invariants instead of a rate-dependent trade. * 🎓 fix: Keep Skill-Bearing Event Actors on the Legacy Path Skill primes are spliced into the message list directly ahead of the newest message, and a warm continuation forwards only that newest message — so a checkpoint-restored actor would keep serving the prime bodies baked in at its last cold start and never observe an edited or newly attached skill. Until the actor head carries a context fingerprint that forces a cold rebuild when the agent's skill context changes, agents with always-apply or manual skill primes stay on the legacy path, which re-primes fresh bodies every turn: correct on every event, just never warm. * 📜 fix: Gate Fork Mode on the Skills Capability, Not Just Request-Time Primes History-derived re-priming was a third path into the same staleness class: an actor that previously invoked a skill carries no request-time prime arrays, yet primeInvokedSkills re-resolves that skill's current body from history each turn and the warm slice drops the reconstruction — leaving the checkpoint's old body active after edits. The fork gate now keys on the priming hook itself (present exactly when the skills capability is enabled) alongside the request-time arrays, so every skill-body path routes to the legacy rebuild until #15235's context fingerprint restores warm continuation for skill-bearing actors. * 🧾 fix: Capture Applied-Action Proof at Tool Execution, Not After sendMessage The executor read applied-action evidence from the run-step collection the instant sendMessage resolved, but that collection is populated asynchronously — an applied invocation could classify as actionless (runSteps still empty while the tool result already streamed), discarding its fork and stranding the actor cold while the terminal handler later settled the same delivery as applied from the persisted evidence. Authoritative proof is now recorded in graph context the moment the expected tool executes: the request-owned recorder observes the tool-end chain (which ToolNode dispatches synchronously with both input and output) and applies the same fences as run-step evidence — exact tool name with the MCP-suffixed form, the declared argument subset against the execution input, an error-free result, and the background non-execution receipt exclusion. readAppliedAction consults the receipt first; run-step inspection remains the fallback for paths that bypass the tool-end chain. Regression coverage reproduces the observed ordering: the real executor commits the head from the receipt while run steps are empty, warm-continues the next event, and never re-executes the action; recorder fences and the receipt-first controller wiring are covered separately. * 🎯 fix: Supply Execution Arguments to the Tool End Callback The live Vertex + MCP canary exposed a contract mismatch the synthetic fixtures hid: the ON_TOOL_EXECUTE execution path invoked its tool end callback with output only, while the action recorder must verify the declared argument subset against the execution input. The receipt never qualified, every turn fell back to cold history rebuilds, and the tournament advanced with zero actor heads and zero retained checkpoints while looking successful. The execution handler owns both halves at the same moment, so the fix is at the source rather than a correlation store: ToolEndCallbackData gains the executed call's input and every callback site passes tc.args. A handler-level regression drives the real createToolExecuteHandler and asserts the callback receives both fields; recorder regressions pin the production shapes — an output-only tool end must starve an argument-fenced receipt rather than trust an unfenced match, and still qualifies a name-only expected action. * 🕵️ fix: Mark Background Deliveries So They Cannot Impersonate Applied Actions The background-claim callback reports the ORIGINAL tool's name for artifact attribution on the poll turn that harvests a completed task. A name-only expected action could therefore be impersonated by work some earlier turn dispatched: the recorder would attribute that delivery to the current invocation and commit a head whose state never contained the invocation's own action. The run-step evidence path never had this hole — it sees the poll tool's name — so the recorder must match its provenance discipline. Delivery callbacks now carry an explicit backgroundDelivery marker set at the one site that rewrites the name, and the recorder ignores marked deliveries outright. Regressions pin both halves of the contract: the delivery callback must carry the marker with the poll call's arguments, and a marked delivery can never qualify even a name-only expected action. * 🧿 fix: Version Invalidations, Keep Evidence Ahead of Output Policy, Gate Detachable Actions Three closeout-round findings, each converted into an invariant. Every legacy-path invalidation now advances a durable epoch — including for headless and already cold-marked actors, where the marker alone leaves no CAS-visible trace — and the actor-head CAS requires the epoch observed at preparation. A concurrently prepared fork whose history predates an intervening legacy turn can no longer commit past it; the commit reports an ordinary conflict and journals. Execution identity is now emitted before post-execution output policy: when a side-effecting tool succeeds but its returned content is withheld by the output filter, the callback delivers an outputFiltered receipt with blank content — the recorder accepts it as proof (rejecting model-detached calls it cannot distinguish through the blank shape), the artifact path never sees it, and an applied action is no longer reclassified actionless and re-executed on retry. Background-capable expected actions stay off the fork path: dispatch returns a launch handle every evidence fence correctly rejects, and the completion is provenance-marked as another turn's work, so a fork would settle actionless before the external effect lands with nothing to stop a retry from dispatching it again. The gate mirrors the MCP-suffix name matching of the evidence path. * 🚧 fix: Seal the Whole Legacy Turn Behind a Second Epoch Advance The epoch fenced only the legacy turn's start: a fork preparing after the begin invalidation but before the turn's message persistence observed the new epoch and cold marker, rebuilt from history that did not yet contain the turn, and committed cleanly because nothing advanced the epoch again — making the incomplete rebuild authoritative and clearing the marker. Every legacy event turn now seals its invalidation at terminal persistence with a second epoch advance, on the success, replaced-claim, and error exits alike. Sealing deliberately carries no quiescence requirement — it must succeed while a fork fence is active, because that is exactly the mid-turn race it defeats — and a fork that already committed against the begin epoch is healed the same way: the seal re-marks the head cold, so the next event rebuilds with complete history. Seal failure never diverts the turn's own exit; the begin bump still fences everything prepared before the turn. * 🔗 fix: Replace the Best-Effort Epoch Bump With a Durable Legacy-Turn Fence The second epoch advance could not make a legacy turn atomic, and three findings shared that root cause: two conditional updates left a headless gap a fork could create the head inside; the error exit sealed before saveErrorTurn made the error history durable; and any crash or failure between persistence and sealing left an incomplete fork authoritative, because the seal was best-effort and its failure was swallowed. A legacy turn now carries one durable fence. A token is written before execution by a single update-pipeline write — no two-write gap, and the cold marker is applied only where a head exists via $cond/$$REMOVE. While the token is present no fork may prepare (the adapter refuses) or commit (the CAS requires its absence), because the turn's messages are not yet durable. One atomic write clears the exact token and advances the epoch once history is persisted — after saveErrorTurn on the error exit — and success, replacement, and error exits all route through it. Failure is now fail-closed rather than silent: a failed seal leaves the token set, which keeps blocking forks and is logged as such, and a fence abandoned by a crashed turn is reclaimed only once stale, advancing the epoch and marking any head cold so the next event rebuilds from whatever history actually survived. * fix: serialize legacy event actor turns * fix: close legacy actor fence ownership gaps * fix: preserve legacy actor persistence fences	2026-08-26 08:39:00 -04:00

Danny Avila	ac2aef00f6	🫗 fix: Drain Quoted Excerpts Into Mid-Run Steering (#15175) ... * 🧭 fix: Carry Quoted Excerpts Through Mid-Run Steering "Add to chat" quote chips were dropped by every during-run steer path: the steer POST had no quotes concept, so a composer-origin steer left the chip staged (gluing onto the NEXT send) and a queued item steered into the live run lost its quotes silently. Quotes now ride the steer protocol end to end: - POST + admission: `quotes` on the steer body, normalized like the chat route's (getReferencedQuotes caps), part of the idempotency fingerprint only when present so pre-existing receipts still replay. - Injection: merged into the model-bound turn as Markdown blockquotes at both boundaries (text-only and media paths), mirroring prependQuotes. - Persistence + replay: the STEER content part stores `quotes` separately from the typed text; stampSteerPartMedia re-merges them per turn (even with resendFiles off) via the SDK's transient media stamp, with the quote block folded into the token budget. - UI: composer steers/interrupt-steers drain the chips (skill picks stay staged — they configure a NEW turn's run); SteerPart and the in-flight bubble render the same MessageQuotes reference blocks as user bubbles; queued/failed rows show a quote count; reconnect reseeds fall back to the server item's quotes when no local chip survives. - buildMessages keeps its zero-await path to the parallel context kickoff via a synchronous stamp-target probe. * 🧭 fix: Keep Quotes in the Client-Safe Steer Projection toPendingSteer is the projection behind resume-state pendingSteers, abort responses, and terminal leftover claims — dropping quotes there would lose them on exactly the recovery paths the reconnect reseed's server fallback relies on. * 🧪 test: In-Flight Steer Bubble Renders Carried Quotes * 🔁 fix: Re-Stage Quotes When a Pre-Quotes Replica Accepts the Steer Codex flagged the rolling-deploy window: an old replica 202s a quoted steer while dropping the excerpts, so the client cleared the chips for context the model never received. The 202 (fresh and receipt replay) now echoes quotesAccepted from the DURABLE item; a missing echo on a quote-bearing composer-origin steer re-stages the excerpts as composer chips — the pre-steer behavior, so they ride the next send instead of vanishing — and strips them from the surviving chip so a later terminal conversion cannot duplicate them. Queued-origin steers keep quotes on the item, whose restore paths already return it intact. The residual cross-version lost-ACK retry stays fail-closed as a 409 idempotency conflict (failed chip with retry controls). * 🔁 fix: Close the Remaining Cross-Version Quote-Loss Windows Codex round 2: - Send now of a quoted queued item against a pre-quotes replica now re-stages the excerpts too (the row is consumed and the words inject bare, so the composer is their only remaining home); the strip clears the chip's captured origin copy so reclaims and terminal conversions cannot duplicate them. - A quoted retry whose lost first ACK was accepted by a pre-quotes replica now REPLAYS that legacy receipt instead of 409ing: the stored fingerprint matching the quote-less hash of the same words proves the cross-version case, and the replayed 202's missing echo drives the re-stage. Different quotes against a quote-bearing receipt still conflict. - TSteerAppliedEvent.part gains the quotes field (typed SSE consumers). * 🧪 test: Drop the Stale Narrow SteerDrainOutput Alias The spec's local intersection re-declared injectedMessages with content: string, predating the SDK pin that declares the field natively (content: string | MessageContentComplex[]). Under CI's clean install the hook's BaseHookOutput is no longer assignable to that narrower alias; the plain PostToolBatchHookOutput is the correct type for every drain/boundary assertion. Verified against the published 3.6.16 dist and the local one. * 🔁 fix: Honor the Generation Owner's Quote Capability End to End Codex round 4: - steerQuotesCapable rides job metadata (createJob + HITL resume rewrite), mirroring preemptCapable's owner-recorded pattern: an upgraded admission replica no longer stores quotes — or claims them accepted — for a generation whose older owning drain would silently drop them at injection. The missing echo drives the client re-stage, and a later capable handover cannot double-deliver restored context. - Applied events reconcile dropped quotes: when a quote-less applied part settles a quote-bearing chip (the lost-202 ordering the ACK-echo path cannot see), resolveSteerChip and both reconnect settle paths re-stage the chip's excerpts before removing their only copy. mergeRestagedQuotes dedupe keeps every trigger idempotent for the same excerpts. * 🔁 fix: Re-Read Quote Capability at the Last Moment and Cap Restaged Chips Codex round 5: - A HITL resume rewrites steerQuotesCapable without changing the generation's createdAt, so the enqueue fence cannot see a capable-to-legacy handover landing during admission's awaits. Re-read the owner's flag immediately before item construction (paid for only by quote-bearing requests); the residual between re-read and enqueue commit matches preemptCapable's documented race. - mergeRestagedQuotes now respects the 10-quote contract with the staged chips winning: a restored tail that cannot ride the next send is dropped explicitly instead of rendering as a chip the submission would silently discard. MAX_QUOTE_COUNT moves to utils/steer as the single client source; QuoteButton imports it. * 🔁 fix: Steer Quote Coverage for Preflights, Memory, and Single-Scan Stamping Codex round 6: - Stored-message policy inspection now extracts steer-part quotes as quote fragments (path /content/N/quotes/M), so conversation import and shared link preflights inspect the newly persisted field exactly like top-level message.quotes. - The memory copy gets its own quote-merge stamp (text only, resendFiles false): formatAgentMessages ignores part.quotes, so without it a steer whose substance lives in its excerpt reached the chat model but never memory extraction. - collectSteerStampTargets replaces the boolean probe: buildMessages collects once and hands the targets to stampSteerPartMedia, keeping the zero-await fast path without scanning the history twice. * 🔁 fix: Redis Quote Plumbing, Conversion-Race Guard, and Quote-Bound Recovery Proof Codex round 7: - RedisJobStore.deserializeJob now restores steerQuotesCapable (the explicit mapper otherwise dropped it on every read, leaving quote steering inert in Redis deployments), with the round-trip spec extended. - Both Lua parked-steer projections (terminal close + generation replacement) forward item.quotes, matching toPendingSteer — a lost final no longer strips excerpts from durable recovery in Redis mode. - The no-echo restage reads the SURVIVING chip (reclaimRejectedChipQuotes): a terminal conversion that beat the delayed 202 already moved the quotes onto the queued follow-up, and re-staging them again double-delivered. Regression-tested with the conversion-before-ACK ordering. - RecoveredSteerPayload binds normalized, order-significant quotes (builder, validator, TS matcher, and the Lua decode+matcher): a stale client presenting the same recoverySteerId with altered or missing quotes cannot consume the parked source. Quote-less sources keep matching quote-less recoveries. * 🔁 fix: Execution-Bound Quote Capability with an Atomic Enqueue Predicate Codex round 8: - steerQuotesCapable becomes a transient assertion translated (at createJob and in ApprovalLifecycle.resolve) into steerQuotesExecutionId, valid only while it equals the LIVE providerExecutionId. A legacy replica winning a HITL resume rewrites the execution id without knowing the marker, so its stale assertion self-invalidates — a bare boolean could not be cleared by code that predates it. - The fenced enqueue evaluates that equality atomically (all three Redis scripts decode-and-strip like the existing preemptCapable normalization; both InMemory sites mirror it) and returns the persisted item, so the quotesAccepted echo reflects exactly what was stored even when a handover lands between admission's read and the commit. The last-moment re-read is gone — the transaction is the authority. - Tests: capable-resume re-binding, legacy-resume omit-not-clear invalidation, the admission-vs-handover race (capability read true, then execution rewritten before enqueue), and the Redis round-trip of the marker. * 🔁 fix: Full Redis Parking Coverage and Loss-Moment Quote Restaging Codex round 9: - The two remaining Redis parking projections (terminal status CAS and stale-running cleanup) forward item.quotes — every field-picked steer projection now carries them (audited: 2 Lua 'projected' + 2 Lua 'clientItem' + toPendingSteer). - The ordinary no-echo ACK no longer re-stages: the steer has not injected yet, so the quotes stay carried on the pending chip. A quote-less applied event re-stages them at the actual loss; a terminal leftover conversion carries them onto the recovered row, whose normal send delivers quotes on any server — re-staging at the ACK let that leftover auto-send bare text while the excerpts glued onto an unrelated draft. Only the settled receipt replay (already injected, no future event) reclaims immediately. * 🔁 fix: Legacy-Replayable Receipts with Separate Quote Identity Codex round 10: an upgraded-first receipt stored a quote-inclusive fingerprint no pre-quotes replica could recompute, so a lost-ACK retry routed through one 409'd already-accepted words with duplicate-send controls. The durable fingerprint reverts to the quote-independent 3-field hash — the one shape EVERY deployed version computes, replayable across a rolling deploy in both directions — and quote identity moves beside it as requestedQuotesFingerprint (of the REQUESTED quotes, pre any capability strip, so an incapable-owner acceptance still replays its own retries). Absent records (legacy-written or quote-less) accept any same-words retry, preserving the round-5 rule; present records must match exactly, keeping different-quotes clientSteerId reuse a 409 on quote-aware readers. Under the keep-on-chip client contract a legacy replay's missing echo is harmless — the excerpts stay carried on the pending chip. * 🧪 chore: Re-Trigger CI After Dropped Workflow Events	2026-08-24 22:29:13 -04:00

Danny Avila	c2aa688d73	🖥️ feat: Stream PTC Inner Tool Calls as a CLI-Style Trace (#15115) ... * 🖥️ feat: Stream PTC Inner Tool Calls as a CLI-Style Trace Programmatic tool calling runs a whole program inside the sandbox, and the tool calls that program makes open no run step of their own. The card showed one running spinner for the entire execution, with no sign of what the code was doing. Emit a new `on_ptc_tool_call` step event for each inner invocation — once on dispatch, once on settle — and render them under the code as a terminal-style trace: status glyph, tool identity, argument preview, duration, with a failure message printed under the call that produced it. The seam is the tool map the sandbox bridge resolves inner calls against. `instrumentPtcToolMap` proxies `invoke` on each entry and leaves every other property (name, schema, mcp) passing straight through, so nothing about execution changes and emission failures can never fail a tool call. Client state is a per-tool-call Recoil atom keyed like the sandbox-starting and subagent atoms — live for the session, cleared on conversation switch so a finished program's trace stays readable. * 🩹 fix: Address Codex Review on the PTC Tool Trace Five findings, all confirmed against the source before fixing. Scope the trace atoms to a message occurrence. The hook already documents that providers repeat a tool_call_id across turns and even within one message, and `call_id` restarts at :0 for every outer call — so two programs sharing `call_0` merged into one card. Key by (response message id, tool call id) via `ptcTraceKey`, mirroring `subagentProgressKey`; the event's `runId` already carries the message id and the card reads its own from MessageContext. Prune unsettled rows on resume. Inner calls are not content parts, so the resume snapshot cannot rebuild them, and `trackReplayEvent` only persists OAuth events — a call that settled during a disconnect left a spinner that never resolved. Settled rows are real history and stay. Make the argument preview budget-aware. Iterate keys rather than entries so the budget check can actually skip work, and clip against a bounded window so a multi-megabyte value is never collapsed in full to build a 40-character preview. Catch the resumable emission promise. The synchronous try/catch around the emitter cannot observe a rejected `emitChunk`, so a failing transport raised an unhandled rejection per event instead of dropping telemetry. Announce completion to assistive technology. The check glyph is decorative and a fast call renders no duration, so a settled row previously announced no outcome; each row now carries an sr-only status and the visible cell that duplicated it is hidden.

The suite mocks the callbacks module with an object literal, and wiring the new emitter into `initialize.js` without adding it there left the factory undefined at call time. Added it alongside `createAttachmentEmitter`, plus an assertion that it receives the same generation fence as every other resumable emitter — a stale epoch would leak one run's inner calls into the next. `Static checks` — import-order drift in `PtcToolTrace.tsx` and `handlers.ts`, repaired with `scripts/sort-imports.mts`. ESLint and Prettier both passed, so only the dedicated check caught it. `openai.js` and `responses.js` never take the emitter, so their specs were unaffected; verified the initialize mock now covers every name the module destructures.

Respect tool-argument PII filtering (P1). Inner calls never reach `filteredToolArgumentsResult` — the sandbox bridge invokes them directly — so the trace was the one path putting their values on the wire in a deployment that had configured `filters.toolArguments.pii`. When any of the name / arguments / output fields are filtered, the emitter now omits both the argument preview and the failure message, which routinely quotes the argument that caused it. Name, status and duration still report. Drop the light/dark-specific background (P1). `dark:bg-transparent` stepped outside the semantic roles and would lose the intended separation under a custom theme. The pane now sets no background at all and inherits the card's surface, which resolves to the same color the override produced in both default themes and stays correct when a theme reassigns its roles. Bound the live trace (P2). A program looping over a large collection made every event copy an ever-growing array and rendered a row per call. The trace now keeps a rolling tail of 100 rows and counts what it evicted, surfaced as "+N earlier calls" so the cap is never silent. A settle whose row is gone — evicted, or pruned across a resume gap — no longer reappears out of order.

Declare the fixture `code_execution`. Add a guard for the resolution itself: a `direct`-only tool must never appear in the instrumented map. Tracing wraps the eligible map, and this fails if a later change reorders that and lets the trace widen what the sandbox reaches.

Redact filtered inner-tool names (P1). The previous gate suppressed argument and failure previews but the event still carried `name` verbatim, so a deployment whose `filters.toolArguments.pii.fields` includes `name` could see a blocked identifier disclosed through the trace — the one path inner calls take, since they never reach `filteredToolArgumentsResult`. Inner tool names are now inspected once per PTC call with the same `extractToolArgumentContent` + `inspectContent` pair the executor uses; any that trip the policy are left unwrapped, so they still execute and emit nothing. An un-inspectable name fails closed. Follow the trace tail (P2). The row list is a 200px scroller that never moved, so once a program exceeded the viewport the card sat on the oldest calls while live activity accumulated below the fold. Reuse `useFollowScroll` — the hook the code and command panes already use — which pins to the tail while calls are running and yields the moment the reader scrolls up. The host card threads its disclosure state so a collapsed pane is never scrolled invisibly. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MBRQUsPXSvDBnjrSDoXWHP * 📌 fix: Pin the PTC Trace Through Its Final Settle The fourth Codex pass on `4bf68e1`, one P2 finding. `useFollowScroll` returned early whenever `active` was false, so the one change it most needed to follow was the one it skipped. A failing inner call settles by appending its error line in the same commit that clears the last running row: the content grows and the stream ends together, and the pin that would have revealed that line never fired. On an expanded, bottom-pinned pane the failure — the row a reader most wants — stayed below the fold. The falling edge of `active` now pins too, but only when the content changed with it. Ending a stream on its own still leaves the pane where the reader left it, which is what the existing contract promises and what the sibling code and command panes rely on; a reader who has scrolled up is untouched either way. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MBRQUsPXSvDBnjrSDoXWHP * 🔌 fix: Keep PTC Calls That Outlive a Reconnect Fifth Codex pass on `085a83f`; one of its two findings. Pruning rows across a resume gap deleted every `running` row, but a stream gap is not proof the call ended. A call still executing across the reconnect settles normally on the restored live stream — and `applyPtcToolCall` drops a settle whose row is gone, by design, so an evicted row cannot reappear out of order. The call therefore vanished from the trace despite having run, which is worse than the spinner the pruning existed to prevent. Rows are now marked `interrupted` instead of removed. A call whose settle was genuinely lost in the gap reports that honestly rather than spinning forever, and one that survives the gap settles onto the row it opened, reporting its real outcome and duration. `interrupted` is a client-side conclusion, so it widens the row status locally and leaves the wire contract alone. Two cases added: the gap marks rather than drops, and a post-reconnect settle lands on its marked row; plus a render case for the new outcome.

Danny Avila	8c14f03432	🗂️ feat: Scope Scheduled Chats to Chat Projects (#15056) ... * 🗂️ feat: Scope Scheduled Chats to Chat Projects Adds an optional chat-project destination to a schedule, plus the operator config to require one — or to pin every scheduled run to a specific project. Feature: - `chatProjectId` on the schedule row, accepted on create/update, projected on the wire, and carried into the run's conversation through the durable trigger envelope's `run` context. - `interface.schedules.requireProject` refuses schedules that are not filed under a project; `interface.schedules.projectId` pins every run to one project and implies the requirement. - Dialog gains a project picker (required when configured, a read-only row when pinned); the card shows the destination and the new disabled reasons. Invariants: - ONE resolver (`resolveScheduleProjectId`) decides the destination for the write handler, the fire path, and the wire projection alike, and an operator pin OUTRANKS the stored id in all three. Tightening the config therefore redirects — or stops — existing schedules instead of grandfathering where their runs land. A pin implies `requireProject` for the same reason: without it, a row created before the pin would keep firing with no project at all. - Create/fire precheck symmetry, mirroring `resolveAgentFireAccess`: a write this handler accepts is one the next fire also accepts. Any edit leaving a schedule ENABLED re-validates its EFFECTIVE (possibly stored) project, like the existing stored-agent and cadence-floor rechecks. A DISABLING edit skips the requirement, or a schedule auto-disabled for `project_required` could never be turned off. - Fire-time enforcement auto-disables rather than filing runs loose, matching agent_deleted: new `project_required` (requirement raised after creation) and `project_deleted` (gone, or pinned to a project this owner does not have) reasons, both refused BEFORE a billed generation is dispatched, and both advancing so a schedule can never wedge on the occurrence. - `computeCreateDigest` appends the field only when present, so a payload without a project digests byte-identically to one from before this change — a create retried across the upgrade still matches its own row instead of reading as key reuse. - Project reads are scoped to the owner, so ownership and existence are the same lookup; a read ERROR propagates instead of failing closed, so a Mongo blip retries the fire rather than auto-disabling the schedule. The trigger idempotency key hashes principal/event/target and never `envelope.run`, so the added run field cannot destabilize delivery identity. * 🗜️ fix: Keep the Schedule Dialog Inside Its Height Budget The project picker landed as a new ROW in the schedule dialog, which broke the e2e edit spec: `md:overflow-visible` turns off the template's scrolling from `md` up, so the dialog's content must fit the viewport. The extra row pushed the footer's Save button below a 720x1280 window, where Playwright reported a visible, enabled button it could never click — 226 scroll-into-view retries and a 2-minute timeout, on all three attempts. Measured against `dev` at 1280x720 (Save button's bottom edge, viewport 720): dev 688 (32px slack) project row ~790 (off-screen, CI failure) 3-column row 704 (16px slack — half the budget spent) this commit 686 (34px slack, 2px better than dev) The identity row is now three columns — name, agent, project — and its caption moved out of the agent cell to sit full width beneath the row: at a third of the dialog that sentence wraps an extra line, and the row is the tallest thing competing for the budget. The caption is grouped with the row rather than left to the form's own 4-unit rhythm, which spent more height on the gap than the caption occupies. The e2e spec now asserts the button is in the viewport before clicking it, so the next field that overflows this dialog says so in one line instead of a two-minute timeout on a visible element. FOLLOWUPS.md records what the planned dialog controls (multi-day weekly, timezone, attachments) need first: give `ControlCombobox` the `portalElement` prop `Dropdown` already has, portal the popovers into the dialog content, and let the form scroll again. * 🧹 fix: Address Codex Review on Scheduled Chat Project Scope Four P2 findings, all real. Unreachable clearing path (ScheduleDialog). The picker only held live projects, so `com_ui_schedule_project_none` was a PLACEHOLDER — nothing selectable. Once a schedule had a project the owner could never take it away, leaving the server's `chatProjectId: null` path reachable only by API. The picker now carries a real "No project" option whenever a project is optional, and omits it when one is required, where there is nothing valid to select. Placeholder shown for a real project (ScheduleDialog). A stored or pinned project outside the first loaded page had no name in the paged map, and the combobox renders its placeholder for an empty display value — telling the owner a scoped schedule had no project. That one project is now read by id, with the raw id as a last resort: a poor label, but an honest one. Project policy skipped at the resume boundary (service.ts). `claimScheduleResume` re-applied the schedules gate, the revision fence, the kill switch and SCHEDULES:USE, but not the project policy this PR added. Approving a paused run whose project was deleted — or whose owner now sits under a requirement or a pin it no longer satisfies — billed a continuation the very next scheduled fire would refuse and auto-disable the schedule for. The effective-project resolution now runs there too, refused before the lease and the capacity slot so a policy refusal costs nothing and leaves no state to unwind. NOTE: agent access and balance are still not rechecked on resume; that gap predates this PR and is left alone. Per-card project derivation (ScheduleCard). Every card ran the projects hook and rebuilt the full option array, name map, and one icon element per project, to use a single name — O(schedules x projects) per render and per project-list refresh. The hook is split: `useChatProjectNames` (map only, for the panel, which resolves every card's name once and passes it down) and `useChatProjectPicker` (options and pagination, for the dialog's one combobox). The panel skips the query entirely until some schedule actually has a scope. Tests: four at the resume boundary (verified failing without the gate) and four in the dialog spec. The picker selection in one existing test now goes through the search field — the popover's VIRTUALIZED renderer sizes its window from a scroll height jsdom always reports as 0, so with three options it materialized only two. Full schedules e2e re-run green against the rebuilt client. * 🎯 fix: Settle Project-Policy Refusals and Keep Create Retries Idempotent Second Codex round, four P2s. Three were consequences of the resume gate added in the previous commit, which was half-built: it admitted where it should not and stranded the run where it refused. Project policy moves from `claimScheduleResume` into `isScheduleLive`'s `policy` branch. Both entry points consult that branch FIRST, and both already route its refusal through abort-and-settle — so a policy stop now settles the occurrence instead of answering a bare 409 while the job stays `requires_action`, the card keeps reading "Needs approval", and every retry repeats the same 409 until expiry. No change to resume.js: the existing branch does the work. The rule is deliberately NARROW. It refuses only where no valid destination is left — the requirement is on with nothing satisfying it, or the schedule's own project is gone (which also unset it on the conversation). It does NOT refuse because an operator's pin moved: the paused conversation cannot be rebound (`chatProjectId` is excluded from the resume context and the continuation reuses the same conversationId), so refusing would strand a pending approval over a destination it can never reach, for a pin that governs only where the NEXT run lands — which the fire path already redirects. Create retries are idempotent again. Project policy had been applied BEFORE the `clientRequestId` replay lookup, so a raised requirement, a deleted project, or a moved pin could answer 400 for a create that already committed — pushing the client to rotate its key and create a DUPLICATE schedule, the exact failure the key exists to prevent. Policy now applies only to a genuinely new insert, and the digest is computed from the CLIENT's payload rather than the resolved destination, so today's policy can no longer re-digest a genuine retry into a mismatch. An explicit `chatProjectId: null` under a pin is refused rather than silently resolved to the pin. The payload contract defines `null` as clearing the scope; answering 201 while filing under the pin reported success for the opposite of what was asked. Only an OMITTED field takes the pin silently. Tests: five on the policy branch (both refusals verified failing without it, plus guards that a moved pin and a live project still admit) and two on the handlers (the pinned explicit clear, and a committed create recovered by retry after the policy tightened — verified answering 400 without the reordering). * 🧭 fix: Converge the Stored Project on the Destination a Fire Resolved Third Codex round, four P2s. The root confusion behind the resume findings: an operator pin outranks the stored id at fire time, `fireSchedule` sends the pin in the trigger envelope, and the row keeps its old value. The row therefore LIED about where that occurrence's conversation went, and every later re-validation — the resume boundary above all — checked a project the conversation was never filed under. A schedule storing A, pinned to B, with B later deleted and A still live, was admitted for resume into a conversation that had just been unscoped. Fixed at the source rather than at each reader: a fire that resolves a destination different from the stored one writes it back, claim-token fenced like every other worker-side write and deliberately WITHOUT a configRevision bump — this is the server reconciling itself to policy, not an owner edit, and a bump would fence an in-flight occurrence off its own run. Written only AFTER the destination validates, so an unusable pin never lands in the row, and best-effort: the envelope already carries the right destination, so a failed write costs accuracy on a later recheck, never the run itself. The wire projection already reported the pin, so this also stops the row and the UI disagreeing. An explicit `chatProjectId: null` under a pin is now refused on the DISABLING edit path too. The pin check and the requirement are independent rules, and folding them together let `{enabled: false, chatProjectId: null}` skip the pin check entirely, unset the row, and answer with a wire projection still naming the pin. Only the requirement is waived for a disabling edit. The dialog no longer requires a project for an edit that leaves a schedule DISABLED. The server waives the requirement there precisely so a row auto-disabled for `project_required` can still be renamed or tidied up; requiring it in the form made that unreachable, and an owner with no projects could not edit the stopped schedule at all. FOLLOWUPS.md records the two residual gaps with their exact triggers: the sub-second deletion race inside the resume claim window (which needs the effective project persisted per OCCURRENCE plus a distinct policy conflict routed through abort-and-settle), and the fact that convergence happens only when a schedule fires. Tests: four on convergence (pin written, no write when unchanged, no write for a destination that failed validation, fire survives a failed write), two on the disabling-edit pin rules, two in the dialog. Schedules e2e re-run green. * 🔑 fix: Keep an Explicit Project Clear Out of an Omitted Field's Digest `computeCreateDigest` appended `chatProjectId` on `!= null`, so an OMITTED field and an explicit `null` produced the same digest. Because the replay lookup and `matchesCreateIntent` deliberately run before project policy, a request could reuse a pinned create's `clientRequestId` while explicitly sending `chatProjectId: null` and receive 201 describing the pinned row — success reported for the opposite of what it asked, and the pinned-clear refusal the normal create path applies never reached. Now `!== undefined`: an omitted field still digests byte-identically to a payload from before project scope existed, so a create in flight across the upgrade still matches its own row, while an explicit clear is a distinct intent and digests differently. A pre-scope client never sent the field at all, so nothing legacy can carry an explicit null. * 📍 fix: Validate a Paused Run Against the Project Its Own Occurrence Used The schedule-wide convergence from the previous commit was not enough, and the reason is the single-active run index: it covers `status: 'started'` only, so a PAUSED run does not block the next occurrence. While run 1 sat paused in project A, a pin move plus one later fire rewrote the schedule row to B — and the resume policy then validated B while run 1's conversation was still filed under A. Delete A and the continuation was admitted into a conversation that had just been unscoped. That window lasts as long as the pause, not the sub-second race the previous commit documented. The reservation now records the destination THIS occurrence used, and `isScheduleLive` validates that record when given the occurrence's `scheduledFor` — which `resume.js` already reads two lines above the call. No new conflict type and no settlement-path surgery: the refusal rides the abort-and-settle branch that check already has. An ABSENT record falls back to the schedule-level resolution rather than reading as unscoped. A pre-scope occurrence, or one whose row is gone, must never be treated as evidence to stop a run — the fallback keeps legacy paused runs behaving exactly as they do today. Schedule-wide convergence stays: it keeps the row honest for the UI and for every check that has no occurrence in hand. FOLLOWUPS.md now describes the one remaining gap accurately — a deletion inside the claim window, which needs a distinct policy conflict routed through abort-and-settle rather than the bare 409 an `inactive` conflict produces. Tests: three on occurrence-vs-row precedence (the decisive one verified failing without the lookup), two on what the reservation records, and the resume controller spec now pins `scheduledFor` in the policy call. Schedules e2e re-run green. * 🏷️ fix: Tell a Deliberately Unscoped Occurrence From an Unrecorded One The occurrence fallback added in the previous commit conflated two different absences. A post-upgrade run that deliberately went unscoped omitted the field exactly like a row written before the field existed, so both took the fallback — and a paused unscoped run was then validated against the schedule's CURRENT project. Under a requirement or a pin added while it sat paused, that admitted a billed continuation into a conversation satisfying no present policy. The reservation now ALWAYS records its decision, `null` for unscoped, and the read reports `recorded` from key PRESENCE rather than truthiness. Only an unknown record — a pre-scope row, or no row at all — falls back to the schedule-level resolution; a recorded null is the genuinely unscoped occurrence it says it is, and is refused once a project becomes required. The distinction rests entirely on a stored `null` surviving as a present key while a never-written field stays absent, so that is asserted against real Mongo rather than assumed: if it ever stopped holding, unscoped runs would silently start being validated against the schedule's current project again. Tests: two against mongodb-memory-server (recorded null vs never-written vs missing row), plus refusal of a recorded-unscoped occurrence under a new requirement and the preserved fallback for a pre-scope one. Schedules e2e green. * 🔁 fix: Validate an Initial Scheduled Start Against Its Own Occurrence The initial-start policy check in `request.js` called `isScheduleLive(..., { policy: true })` without `scheduledFor`, so it fell back to the schedule-level resolution even though the run row already carries the occurrence's recorded scope. An occurrence reserved unscoped, with a pin introduced while its loopback request sat queued, was therefore admitted against the new pin — producing a billed unscoped conversation under a requirement it does not satisfy, from an envelope already built without a project. `scheduledFor` was already in scope there. Passing it makes the initial start and the resume validate the same way: against the destination the occurrence itself recorded.	2026-08-21 11:09:04 -04:00
Danny Avila	c7e355b219	🛑 fix: Confirm Scheduled Stops and Separate Terminal Scheduler Failure from Startup (#15051) ... * 🛑 fix: Confirm Scheduled Stops and Separate Terminal Scheduler Failure from Startup Fixes #15042, fixes #15043. `resume.js` inferred a confirmed stop from the ABSENCE of `failureReason`, but `abortJob` had four `success: false` paths that returned no reason at all. Those settled the occurrence as `interrupted` and pruned the checkpoint on aborts that never landed — including one where a REPLACEMENT generation owned the conversation, which pruned the successor's checkpoint. Every `success: false` return now names itself (`job_not_found`, `already_settled` added alongside the existing `generation_replaced` / `job_still_active`), and a single canonical `isStopConfirmed` predicate decides whether durable state may be settled. `already_settled` confirms a stop — `awaitProviderDrain` has proven the provider segment can no longer persist — so a permanently terminal generation is not answered with a retry loop. Separately, a schedule engine that failed to arm advertised its permanent outage as a transient 503 with `Retry-After`, so a client obeying it would poll forever. Readiness is now tri-state (`starting` / `armed` / `unavailable`): the retry contract applies only while arming is genuinely pending, and a failed arm returns a terminal `SCHEDULES_UNAVAILABLE` with no `Retry-After` and an error-level log. * 🏷️ fix: Declare Schedule Write Gate Return Types `--isolatedDeclarations` requires an explicit return type on the exported factory and on the middleware it returns (TS9007). Adds a named `ScheduleWriteGate` type matching the existing `ShareMiddleware` shape.	2026-08-20 18:33:51 -04:00
Danny Avila	c5276fc63d	⏱️ feat: Run Scheduled Chats Through Durable Agent Triggers (#14939) ... * feat: Scheduled Chats — agent-centric scheduled runs creating real conversations Squash of the full review-hardened branch (PR 14540, supersedes 14373) onto latest dev, preserving the exact verified tree. History prior to this commit lived on the pre-squash branch; every invariant below survived 25 Codex review rounds plus two external audit rounds (R26) with regression tests that fail without their fixes. Feature: - Schedules CRUD + side-panel UI (cadence dialog, run cards, Run Now), roles/ permissions (SCHEDULES:USE), interface.schedules availability, per-user limits and capacity slots, timezone-aware cadence with DST-conservative floors and misfire grace. - Engine: single-process claim/fire loop with leases, loopback POST dispatch (signed schedule-fire JWT claims, per-occurrence idempotency key inside the route's clientRequestId charset), overlap/balance/capacity/duplicate skip policies with auto-disable streaks (too_many_failures, insufficient_balance), reconciliation from retained terminal-job evidence, erasure sweep. - Scheduled runs create real conversations through the resumable agents chat path: HITL pauses surface on the card (requires_action), resumes re-apply the fire boundary's admission policy (revision fence, enabled, global kill switch, SCHEDULES:USE, availability) before continuing a billed generation. Correctness invariants (the audit surface): - Settlement discipline: every persistence-producing write happens-before a run's terminal outcome write; Stop/complete/pause race through single-winner terminal CAS claims (dev's TerminalJobClaim substrate) with retained, completedAt-less evidence for scheduled fires plus an owner-intended outcome stamp (scheduleOutcome) the reconciler prefers over re-derived success — round-tripped through the Redis hash mapper. - Swallowed generation failures (client error content parts) classify to error/skipped_balance instead of success on both initial and resumed paths; stale stamps are refreshed evidence-first when persistence plus the Mongo outcome write both fail. - Abort honesty: delivery judged by generation ownership and the CAS's actual from-status; republication escalates to the transport's acknowledged variant; the Stop route settles only genuinely paused runs. - Account deletion: one-way barrier (deletionRequestedAt) with auth-cache tombstone-before-stamp, boundary rechecks across all auth strategies, quiesce of scheduled + interactive work with durable per-stream abort fences (positive-evidence acknowledgement only), owner-side finalization markers for post-terminal billed writes, deferred-deletion sweep (explicitly ensured partial index) that completes cascades autonomously. Remote OpenAI-compatible/ Responses requests are documented as outside the quiesce and tracked in issue 14594. - Store compatibility: finalization markers optional on the legacy IJobStore contract with coherent degradation (registration fails -> synchronous title fallback; count reads 0). * fix: fence terminal response persistence from deletion; retain stale-pause evidence Two blockers from the third external review round. Terminal persistence visible to account deletion: - The finalization marker was registered only when post-terminal TITLE work was possible, but every persistence-owning terminal CAS opens the same window: the claim drops the job out of the active set BEFORE the response save (and the background user-message/convo saves), so a deletion quiesce landing there saw neither an active job nor a marker and could cascade while the admitted request could still recreate messages. Both controllers now register the marker before every persistence-owning claim — the fresh-turn path and the HITL resume — and release it only after their pending saves (and any post-terminal title) have landed, on success and failure paths alike. The TTL bounds a crash. - settleAbortFence no longer clears a complete/error fence while `terminalPersistencePending` is set: terminal at the CAS is not settled while the owner is still persisting. The job facade now surfaces the flag. - The marker trio is REQUIRED by the runtime store contract (assertJobStoreV2 refuses a store without it at configure time, keeping the failure loud and deterministic) while remaining optional on the legacy public IJobStore type for source compatibility. The silent degrade path from the previous round is gone — it was not deletion-safe. Stale-pause recovery retains scheduled evidence: - Three crash/timeout recovery paths — ApprovalLifecycle.failStalePausePersistence and the InMemory/Redis stale-pause cleanups — unconditionally stamped `completedAt`, putting a scheduled fire's failed-pause error terminal on the short completed TTL. A Mongo outage longer than that TTL erased the evidence and the reconciler recovered the run as `interrupted` instead of `error`. All three now follow the controller-observed path from the previous round: scheduled jobs omit `completedAt` (retained-evidence TTL) and stamp the error outcome. The PR description now explicitly narrows the deletion guarantee for the remote OpenAI-compatible/Responses paths (tracked in issue 14594). * fix: deletion-fence marker protocol — generation-scoped, atomic, fail-closed, all terminal paths One consolidated pass over the finalization-marker mechanism, per the fourth external review round. The invariant it establishes: NO persistence-owning terminal CAS runs without a durable, generation-qualified marker covering the window it opens, and every consumer treats a pending terminal as unsettled. - Generation-scoped markers. Entries were keyed (userId, streamId), so a Stop-superseded generation finishing late could clear the marker its replacement registered on the same conversation. Marker fields are now qualified by the generation's createdAt; clears must present the same identity, and an unqualified legacy clear cannot drop a qualified entry. - Atomic Redis registration. HSET-then-EXPIRE loses the fresh marker when the user's existing hash expires between the two commands (or the process dies there); registration is now a single Lua script carrying both. - Fail closed everywhere. Registration failure (after one retry) now REFUSES the terminal CAS instead of proceeding uncovered: the completion claim throws into the error path, the error path skips completeJob and leaves the job ACTIVE — deletion-visible by itself, recovered by the stale-running reaper — and abortJob returns a new retryable `fence_unavailable` failure the Stop route answers with 503 and the deletion quiesce treats as an unacknowledged stop (fence kept). The previous round's log-and-proceed is gone. - Every terminal path enrolled. abortJob now owns its window (register before the abort CAS, clear in its finally — the Stop route's checkpoint prune and partial save run inside beforePublish, between CAS and publication); the interactive and background generation-error paths register before their completeJob; the resume controller's error finalization registers before its completeJob. A lost or thrown claim releases the marker after pending saves flush instead of holding the user's deletion behind the TTL. - Every pending terminal unsettled. settleAbortFence defers on terminalPersistencePending for ALL statuses — including `aborted`, whose route-side persistence the previous guard missed. Also: a direct Redis regression for scheduled stale-pause retention (the P2 test gap), and the PR description no longer claims to carry every commit. * fix: lease-token lifecycle fences — same-generation isolation, admission fence, undelivered-Stop retention, legacy abort enrollment Fifth external review round; four P1s, handled as the requested consolidated lifecycle-fence pass. - Lease tokens. Marker fields were (streamId, createdAt), shared by every contender on the same generation — completion and Stop, or two racing Stops — so a losing contender's cleanup erased the winner's still-live marker. Every registrant now carries a unique lease token in the field and may only ever clear its own lease; unqualified legacy clears cannot touch qualified entries. - Admission fence. Authentication can pass before the deletion barrier goes up, and the durable createJob is several async steps later — a deletion quiesce in that window saw neither an active job nor a marker and could cascade before the admitted request created its job. The controller now registers an admission lease and THEN rereads the deletion barrier: the ordering guarantees either this request observes the barrier (403, lease released, slot/claim cleanup) or the quiesce observes the lease and defers. Held until createJob is durable; released on every refusal and initialization-error path. Fail closed when the lease itself cannot be registered (503 retryable). - Undelivered-Stop retention. abortJob released its lease in a finally even when delivery AND publication had provably failed — the job reads terminal (invisible to active-set scans), a user Stop writes no durable abort fence, and the remote owner keeps generating and will persist its abort-catch writes whenever the signal finally lands. The lease is now retained in exactly that case, and each resignal attempt heartbeats a fresh lease so the fence outlives the TTL for as long as delivery is still being driven. The abort-winning turn's own loser-side pending saves are additionally fenced in the controller catch (best-effort — those writes are already in flight). - Legacy abort enrollment. abortMiddleware (assistants abort route fallback for non-assistants endpoints) awaited abortJob and then spent usage and saved the stopped response AFTER the abort's lease was released. Both writes now run inside `beforePublish`, between the abort CAS and publication, covered by the same lease as every other abort. Barrier tests, each verified to fail without its fix: same-generation lease isolation (store), racing two-Stop loser cleanup (manager, stale-read forced CAS race), undelivered-Stop lease retention, resignal heartbeat, admission refusal with lease-before-reread ordering plus release-on-durable-create, and legacy-abort persistence inside beforePublish. * fix: heartbeat-backed owner-lifecycle leases close the settlement handoff races Sixth external review round: the remaining P1 interleavings were one structural problem — lease handoffs that were not atomic — resolved as the requested consolidated lifecycle-lease pass. - Quiesce reads leases BEFORE the active-job scan. The admission-lease -> durable -job handoff is only atomic against a reader in the OPPOSITE order of the writer: writers hold the lease strictly until the job is active-set visible, so leases-first shows every interleaving either the lease or the job. Jobs-first allowed a request to create its job after the scan and release its lease before the count — hiding both, cascading, and letting the new generation persist into a deleted account. - The abort acknowledgement is fenced by the owner-lifecycle lease. Redis ACKed the moment the owner's AbortController tripped; the stopping side released its lease on that ACK while the owner's asynchronous abort-catch persistence was still ahead. The transport now awaits a manager-installed pre-ACK hook that registers a DETERMINISTIC owner lease (exactly one owner exists per generation, and determinism is what lets the signal-time registrant and the owner's catch-side release agree across processes) before the acknowledgement is persisted or published; an owned same-replica abort bridges to the same lease before tripping its local controller. Both generation-owner catches (fresh turn, resume) release it once their writes land. - A failed replacement handoff no longer orphans the predecessor. The atomic replacement removes it from active storage, and an unconfirmed handoff terminalizes the replacement too — leaving nothing a quiesce could discover while the predecessor's provider may still be generating. Its owner lease is now retained at the point the receipt fails delivery; the owner replica renews it through the pre-ACK fence when the signal finally lands. - Leases HEARTBEAT while held. The five-minute store TTL only bounds a crashed holder; live persistence — a stalled save, a long deferred title — must never outlive its own fence. holdUserFinalization registers and renews every minute until released; the controllers' completion/error/admission leases all hold. The undelivered-Stop retention moved to a deterministic `stop` lease that every resignal attempt renews and the first successful one clears (no more opaque leases accumulating to TTL), and a THROWN abort transition releases the contender lease instead of leaking it. - The user-document abort-fence mutations now invalidate the auth user-doc cache, matching every other user-doc write. Barrier tests, each verified to fail without its fix: quiesce lease-scan ordering (plus the observed-lease defer), pre-ACK fence ordering at the transport, owned-abort owner-lease bridging, replacement-handoff predecessor retention, held-lease heartbeat past the TTL, and failed-then-successful resignal reaping the retained stop lease. * fix: one manager-owned owner-lease span across every abort delivery path Seventh external review round; four lifecycle-fence gaps, closed by making the owner-lifecycle lease a single manager-owned, heartbeat-held span. - Fail-closed acknowledgements. The pre-ACK hook registered a one-shot lease and the transport ACKed even when it failed; a same-replica owned abort likewise swallowed registration failure. The hook now acquires a HELD owner lease (heartbeat until the owner's catch releases it via releaseOwnerLease) and a rejection SUPPRESSES the acknowledgement — the stopping side stays retryable behind its retention lease, and every resignal re-drives the handler. The hook also stopped gating on `job.createdAt === generationId`: during a replacement handoff the store holds the replacement while the abort targets the predecessor, and that gate silently skipped exactly the generation being acknowledged (the store job is owner identity, never a generation gate). A local owned abort acquires the same held lease before tripping its provider; post-CAS the trip cannot be withheld, so acquisition failure downgrades delivery and the retention handoff keeps the user fenced. - Committed-but-lost-reply disambiguation. A thrown abort transition released the contender lease as if nothing had happened, but a Lua CAS can commit and lose its reply — an aborted job invisible to active-set scans whose provider was never signalled, with no fence left. The throw path now re-reads the exact generation: only a job still live under the caller's identity proves no commit; committed or ambiguous outcomes hand the fence to the deterministic stop lease (kept on the contender lease if even that fails) before rethrowing. - Replacement handoff covered end to end. A LOCAL replacement abort acquires the predecessor's held owner lease before the trip (failure reports the receipt undelivered, engaging retention). Failed-handoff retention is no longer a swallowed one-shot: it heartbeats with the durable acknowledgement proof as its renewal predicate — acquisition failures keep retrying for as long as the fence is needed, and the retainer stands down (without clearing the shared field) once the remote owner ACKs and thereby holds its own lease. - A LOCAL resignal delivery hands off to the owner lease BEFORE clearing the retained stop lease, and keeps the stop lease when that handoff fails. Barrier tests: hook rejection suppressing the ACK, commit-then-lost-reply retention with its provably-uncommitted counterpart, local-resignal owner handoff ordering, pre-ACK owner lease held past the store TTL until release (and provably stopped after), and failed-handoff retention retrying on its heartbeat — verified fail-before/pass-after by stashing the fixes. * fix: finish scheduled chat lifecycle hardening * fix: close scheduled chat review follow-ups * fix: generation-fence abort recovery evidence * test: wait for settled approval tool output * test: preserve scheduled init reconciliation option * refactor: rebuild scheduled chats on durable agent triggers * test: reset MCP cache mock between cases * test: isolate scheduler startup in server specs * fix: harden scheduled run lifecycle * fix: normalize schedule capacity conflicts * test: type schedule collision fixture * fix: re-fence scheduled resume and expiry * fix: fence scheduled resume handoffs * fix: release superseded manual schedule leases * fix: release failed run-now claims * fix: release superseded engine claims * fix: repair schedule dialog interaction and rework its form The agent picker was unusable: ControlCombobox portals its popover to the body by default, which lands it outside the dialog's Radix focus trap. Clicks passed through it, it could not be tabbed into, and the trap fighting Ariakit for focus locked the page up on selection. The prop is documented for exactly this case — pass `portal={false}` and give the dialog `overflow-visible`, as ProjectButton already does. The time and day dropdowns defaulted the same way. Alongside that: - Extract the agent builder's instructions editor (special-variable menu plus expand-to-fullscreen) into a controlled `VariableEditor` and use it for the schedule prompt. Insertions now route through `onChange`, so react-hook-form sees them — the schedule PATCH is built from `dirtyFields`, and a `setValue` that skipped dirty tracking would have dropped an inserted variable silently. - Replace the hand-rolled frequency buttons with the shared `Radio`. They marked the selection with `bg-surface-hover` on an outline button whose hover is the same token, so the selected option was indistinguishable from a hovered one; `Radio` is also a real radiogroup rather than four `aria-pressed` toggles. - Wrap the fields in a real `<form>` and associate the footer button by id, so Enter submits. Group the frequency, day and time controls in fieldsets. - Add placeholders for name and prompt, match the textarea fill to the other fields, and label the hourly case as minutes past the hour. - Widen the dialog to `md:max-w-3xl` and pair name with agent so the form fits without scrolling on desktop. - Move scheduled chats below skills and above prompts in the side nav. The new dialog spec fails when the portal fix is reverted. * test: cover scheduled and subagent deletion drains * refactor: own the form-control appearance in the client primitives Addresses the codex finding on ScheduleDialog: a feature-local `FIELD_CLASS` restated the `Input` primitive's border, radius, height and background so it could be pasted onto the schedule dropdowns, leaving those controls with no connection to the primitive they were imitating. Move that appearance into `packages/client/src/components/Field.ts` as the single source `Input` and `Textarea` now compose, and give `Dropdown` and `ControlCombobox` a `variant="field"` that applies it. The schedule dialog passes the variant and carries no class strings of its own. This also repairs a break the dev merge would otherwise have introduced: the newer `Dropdown` splits `className` (wrapper) from `triggerClassName`, so the old pasted classes would have landed on the wrapper and left the triggers unstyled. The semantic-token guard now watches the shared module and asserts each primitive still composes it, which covers more than the two files it read before. * fix: keep an explicit schedules disable from becoming an opt-in `use` is two things at once for a dual-purpose runtime interface field: a permission bit, which DB overrides strip, and the runtime disable signal that `getLimits` reads. Stripping it from `{ use: false, maxPerUser: 2 }` leaves an object, and `getLimits` treats any object without `use: false` as enabled — so an admin override written to stop scheduled billing for a role or user started it instead. Collapse an explicit disable to the boolean form before the strip, on both paths that accept it: the `interface.schedules` field patch, which admitted the object wholesale because bare runtime paths deliberately bypass the permission gate, and the overrides merge, which reached the composite-field branch and kept `maxPerUser`. Objects that only narrow limits are untouched, so a principal can still be given a smaller cap. Both regressions fail without the normalizer. * fix(schedules): Wave A — null-balance CAS, atomic paused-card clear, clustered erasure sweep Slice 1 (thread r3804518381): route the existing-null balance initialization through a { user, tokenCredits: null } compare-and-set instead of a blind $set, so a concurrent initializer/charge landing between the preflight read and the write is never handed back its spent starting balance. On a CAS miss the preflight re-reads the winner. The absent-record $setOnInsert path and the credited-record refill-config sync are unchanged. Adds the initializeNullBalance adapter (no upsert) and regression coverage for winner/miss/sync cases. Slice 2 (thread r3804518388): updateScheduleById now drops a `requires_action` lastRun projection atomically with the configRevision bump. Any pause present at edit time was projected under the pre-edit revision and can never be replaced by its own revision-fenced terminal outcome — a disabling edit would strand the card on "Needs approval" forever. Implemented as classic-operator CAS branches (DocumentDB rules out a conditional pipeline $unset), fenced on the card STILL being the pause so a terminal outcome or newer occurrence that races in is preserved. Terminal history survives untouched. Slice 4 (thread r3803826204): expose initializeScheduleErasureSweep from the schedule runtime facade and start it in every clustered (experimental) worker after Mongo is up. It re-drives eraseScheduleIfDrained for soft-deleted rows so a hidden prompt cannot outlive its drain when the delete/erase-on-settle attempts miss. It arms nothing else and never infers owner death from a process-local missing job (isTopologySafeToArm gates that).

Account-deletion quiesce marked every schedule `deleting`, disabled it, and cleared nextRunAt destructively. When a later cascade step (or the drain itself) failed, the controller cancelled the user-deletion fence — restoring the user — but the schedules stayed `deleting` and were erased by the sweep, silently losing all of a live user's scheduled prompts. Replace the destructive marking with a REVERSIBLE, token-fenced suspension: - suspendUserSchedulesForDeletion(userId, token) snapshots each schedule's prior enabled/nextRunAt under a per-attempt token, then fences firing (disable, clear nextRunAt, rotate claimToken). It never sets `deleting`, so a suspended row is not erasure-eligible. Snapshotting reads then bulkWrites (a classic update cannot copy field values under DocumentDB), fenced per row so an already- suspended/soft-deleted/edited row is left alone; idempotent per token. - restoreUserSchedulesFromDeletion(userId, token) reverses it, re-enabling and re-arming only rows still carrying the exact attempt token and not independently deleted — so an owner-deleted or newer-attempt-suspended schedule is never resurrected. - deleteUserController generates the attempt token, passes it to quiesce, and on any failure that cancels the user-deletion fence restores the suspended rows. A successful deletion hard-deletes them (and their snapshots) via the existing cascade and never restores. Adds a `deletionSuspension` embedded field (excluded from the wire schedule), data-method regression tests (suspend/restore/fence/idempotency/no-resurrect), and controller tests (restore on drain-false and post-quiesce cascade failure, no restore on success).

The durable Stop primitives (requestRunAbort 'stop', getScheduleRunAbortState, markRunAbortPersisted) already existed but production only used requestRunAbort(..., 'deletion'). An interactive Stop flipped the job to `aborted` and then persisted its partial message + checkpoint inside `beforePublish`, without ever stamping the schedule Stop or acknowledging it — so reconciliation, the generation owner, or a concurrent schedule/account deletion could terminalize the run and release its capacity (and erase data) mid-write. Wire the request -> persist -> acknowledge -> settle barrier through the schedule runtime (the route never touches raw Mongo): - Expose beginScheduledStop / acknowledgeScheduledStopPersistence on the service. - The abort route stamps the Stop BEFORE signalling abortJob (a serialized 'in_progress' loser returns 409 STOP_IN_PROGRESS without a second abort), acknowledges only after beforePublish persistence succeeds, and on a persistence failure leaves the barrier unresolved so the run stays preserved (client retries; stale-owner timeout is the bounded recovery). A failed abort releases the stamp it placed so a replacement/retry is never blocked through its predecessor. - recordScheduleOutcome (the owner settlement path) now waits, bounded, for the Stop acknowledgement before terminalizing; a resolved/non-stop/stale marker proceeds immediately. The paused Stop settles only after its own ack. Adds service-layer barrier tests and route-level ordering/persistence-failure/ in-progress tests; the data-layer serialization is already covered.

And a valid delivery deferred by Retry-After (up to 24h) could be orphan-settled and have its capacity released, then fire anyway. Translate durable delivery state into the schedule outcome: - Store the deterministic trigger deliveryKey on the ScheduleRun reservation (computed from the envelope BEFORE enqueue, so an ambiguous commit still has it). - Add a getTriggerDelivery engine dep (wired to the merged trigger service's getDelivery) that reads the durable delivery by key. - Schedule reconciliation, for a jobless `started` run: staging/pending/leased → admission is live, never orphan; dead → record `error` from the durable lastError and release capacity promptly (no 30-minute wait), through the ordinary outcome/auto-disable path; succeeded or no record → the existing legacy orphan policy (interrupted only past the cutoff); a delivery lookup failure defers rather than orphaning a possibly-live delivery. Limiter/PII/ moderation middleware writes no schedule state. Adds reconcile state-mapping tests (dead/pending/leased/staging/succeeded/none/ lookup-failure) and a fire test that the reservation's deliveryKey equals the enqueued delivery's idempotency key.

Approval expiry won the `requires_action → aborted` CAS and then invoked the host hook best-effort: `runApprovalExpiredHandler` swallowed a failure, and because later sweeps enumerate only `requires_action` jobs, the now- aborted job was never offered again. In the clustered entrypoint (no schedule reconciler) the ScheduleRun stayed `requires_action` and its retained job persisted indefinitely. Make the host lifecycle work durable rather than schedule-specific: - Add a generic `terminalHostActionPending` marker, set ATOMICALLY in the same terminal transition (ApprovalLifecycle.expireWithIdentity), only when a host adapter is installed. - Retain and index such jobs: both stores keep them out of terminal reaping and expose getTerminalHostActionJobs(); Redis adds a set + extended (24h-bounded) TTL, in-memory a bounded 24h retention so a permanently-failing hook cannot leak. - The manager clears the marker only after the adapter acknowledges success, fenced by generation identity (clearTerminalHostAction), so a replacement generation can neither clear nor execute its predecessor's action. - cleanup()/expireStaleApprovals() enumerates unacknowledged terminal host actions across restarts and replicas and retries the idempotent hook; the relay only re-invokes while the marker is unacknowledged, so a successful ack prevents duplicate work. Store-won expiry marks it too, so a loser-replica relay still crosses the hook. - Terminal SSE notification continues regardless of host-hook outcome. Covers in-memory behavior (retry after failure, restart/other-replica retry, ack prevents duplicates, identity fence, terminal notification on failure, no marker accumulation for non-scheduled jobs) and updates the Redis cluster-membership contract test for the new index.

P1 — config/delete-user.js called methods.disableUserSchedulesForDeletion, which Wave B removed in favor of suspendUserSchedulesForDeletion. The file is @ts-nocheck and its spec mocked the removed name, so neither typecheck nor tests caught it; the real CLI would throw a TypeError before deleting anything and then only unwind the fence. The CLI now uses the tokenized protocol: it mints a suspension token, suspends with it, and restores that exact attempt's rows in its finally block when the deletion does not commit. Its spec mocks the real methods, so the breakage can no longer hide. P2 — both the HTTP controller and the CLI released the user-deletion fence BEFORE restoring schedules. That fence is what refuses new schedule writes/claims, so the gap let an owner PATCH edit a still-suspended row and have its enabled/next-run state overwritten by the older snapshot, and let a second deletion attempt re-suspend under a new token — making the first restore a no-op and stranding the disabled snapshot permanently. Restore now runs first, while writes are still fenced. Hardening for the same defect class across a crash: suspendUserSchedulesForDeletion now ADOPTS an existing suspension's snapshot when re-suspending a row abandoned by an earlier attempt, instead of re-capturing the row's current (already-suspended) state. Without this, an attempt that died before restoring would have its successor snapshot "disabled, no next run" and permanently strand the schedule. Tests: CLI restore-before-fence ordering and no-restore-on-success; the same ordering assertion on both controller post-quiesce failure paths; a data-method regression that a second attempt adopts the abandoned snapshot and restores the original enabled/next-run state. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CZwZPDBgxy4mCWWg6zQSjq * fix(schedules): converge dead deliveries in topology-safe maintenance Codex finding: the `dead` delivery mapping added in Wave C.1 lives only inside startScheduleEngine's reconciler, but the clustered entrypoint arms no engine — it runs erasure-only maintenance. A delivery queued before a restart into clustered mode and then rejected before generation creation (interactive limiter, PII, moderation) dead-letters while its ScheduleRun stays `started`, holding a global capacity slot indefinitely for an ordinary non-deleting schedule. Add a dead-delivery convergence pass to the erasure sweep, so every topology that runs schedule maintenance settles it. The pass is POSITIVE-EVIDENCE-ONLY and is therefore safe where absence-based reconciliation is not: a `dead` delivery is durable shared state proving no generation owns the reservation. It settles only when the job is confirmed absent or identity-mismatched (an identity-matched job still owns the run), defers on an unknown job lookup, on an in-flight abort, and on an in-flight resume hand-off, ignores legacy reservations with no deliveryKey, and applies a short grace so an accepted delivery still creating its generation is never settled mid-handoff. Auto-disable policy is deliberately left to the armed engine; this path records the failure and frees the slot. Deliberately does NOT touch api/server/experimental.js — the clustered entrypoint already starts this sweep, so the convergence arrives through the existing initializer and the shared-file footprint stays as-is. Tests: settles a dead delivery as error under an explicitly UNSAFE topology, leaves live deliveries alone, never settles under an identity-matched running generation (delivery is not even consulted), defers an in-flight abort, and ignores a reservation with no deliveryKey.

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

Slow checkpoint cleanup is indistinguishable from a dead route on that signal, so the timeout was being treated as if the barrier had been satisfied. The poll budget now means "undecided", not "clear". On timeout with a fresh, unacknowledged Stop the barrier DEFERS: recordScheduleOutcome returns false without recording, leaving the run active/preserved. Settlement then happens either when the route acknowledges, or once the existing stale-owner cutoff (ABORT_OWNER_PRESUMED_ALIVE_MS) authorizes a later attempt — which the loop already treats as clear-to-settle. Callers with durable retry (the approval-expiry host action, reconciliation) re-drive it, so a deferral converges rather than stranding the run. Test: a fresh Stop that never acknowledges within the budget reports not-settled and records no outcome. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CZwZPDBgxy4mCWWg6zQSjq * fix(schedules): require definite delivery failure, extract its message, converge deferred Stops Third Codex round. Three findings in code from this closeout, plus one pre-existing P1 that is a one-line operator-safety fix. P1 — dead-delivery settlement demanded too little evidence. `dead` does not prove a request was rejected: the trigger host marks response timeouts and invalid success responses `certainty: 'ambiguous'`, and the engine dead-letters those once retries are exhausted. The erasure sweep treated every dead letter as positive evidence, so an ambiguous one sitting over a generation a peer had accepted could terminalize the run and release its capacity mid-flight. It now settles only on a DEFINITE rejection, unless job absence is deployment-authoritative (safe topology), where the confirmed-absent job is itself the evidence. P1 — `lastError` is an `AgentTriggerDeliveryFailure` object, not a string. A duplicated local interface declared it `string` (against CLAUDE.md's no-duplicate- types rule), so both the sweep and the engine reconciler passed the object into the String-typed run/schedule `error` fields; Mongoose would reject the cast, the per-row catch would swallow it, and the run would keep its global capacity slot. The dep type now reuses the canonical `AgentTriggerDeliveryFailure` and both call sites pass `.message`. Re-typing immediately surfaced a stale test that had asserted a string. P1 (pre-existing) — the base-config global stop is honored in `getLimits` via `isRuntimeDisabled` rather than a literal `=== false`. The stop has two shapes, and deepMerge turns base `{ use: false }` plus a principal override of `true` into `{ use: true }`, so the literal check reported the feature enabled and Run Now dispatched straight through fireSchedule, bypassing the operator's emergency stop. Now the same predicate the engine gate already uses. P2 — a Stop whose settlement DEFERRED past the poll budget had no convergence path where no reconciler is armed. `acknowledgeScheduledStopPersistence` now optionally re-drives the terminal outcome once the barrier clears; `recordRunOutcome` is match-guarded and idempotent, so an owner that already settled makes it a no-op. The abort route passes it for a running generation; a paused job still settles explicitly. Tests: ambiguous dead letters refused under unsafe topology but settled when absence is authoritative, definite rejections settled either way, the failure message carried through, and the abort route's re-drive present for running / absent for paused. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CZwZPDBgxy4mCWWg6zQSjq * fix(schedules): converge terminal runs in clustered workers, retry suspension restore Fourth Codex round on 74f7af8. Both findings are in code from this closeout. P2 - a clustered worker never settled a run whose generation finished but whose outcome write failed. `recordScheduleOutcome` retries three times and then returns false; the owner honors that by PRESERVING the terminal job as the only surviving evidence, and the armed engine's reconciler replays exactly that. The clustered entrypoint arms no engine, and its sweep only covered deleting schedules (settleAbandonedRuns) and dead deliveries - an identity-matched job was skipped outright. So an ordinary live schedule's run stayed `started`, held its GLOBAL capacity slot, and kept a preserved job that carries no `completedAt` and is therefore invisible to the store's finished-job sweep: both leaked until store expiry. The live-schedule pass now also converges from a retained terminal job, mirroring the reconciler branch it stands in for: honor the owner's stamped outcome over the generic status (so a balance refusal still walks its streak rather than resetting it), clear the reserved conversationId when the generation never emitted its created event, and delete the retained job only AFTER the outcome write is durable. This stays positive-evidence-only and safe in every topology. Presence, not absence, is the evidence: an identity-matched job is authoritative wherever it is observed - a shared store shows the real generation, a process-local store can only be showing this process's own - which is why it needs no canInferOwnerDeathFromMissingJob fence, unlike the absence-based paths. The in-flight abort/resume fences still defer, so an `aborted` job cannot settle a run whose owner may still be persisting. Both cases now share one pass over one window rather than two, and `retainedOutcome` moved to types.ts so the sweep reuses the engine's mapping instead of duplicating it (and stays independent of the engine). P2 - a failed restore stranded a live account's schedules. Cancelling an account deletion restores the suspended rows while the deletion fence is still armed and then releases that fence; nothing re-drives the restore afterwards, so one transient write failure left the user with silently disabled, next-run-less schedules. The restore is now retried at the single choke point both the HTTP controller and the CLI share. Retrying is safe because each attempt re-reads only the rows STILL carrying the token: a partially-applied unordered write converges on exactly the stragglers, and a fully-applied one finds nothing. The fence is still released when every attempt fails, deliberately: retaining it would refuse the live account's schedule writes AND make beginAgentTriggerUserDeletion report `in_progress` forever, blocking the retry that is the convergence path (a later attempt adopts this snapshot, so its cancel restores these exact rows). Both callers now log the user id and suspension token so the state stays recoverable by hand if that never happens. Tests: retained terminal job settled and its evidence released, stamped outcome preferred over the generic status, stamped failure reason carried, reserved conversationId cleared for a never-created conversation, identity-mismatched terminal job ignored, abort-in-flight deferred; restore retried past a transient write failure and converging on a partially applied restore.

Both are in code this PR introduces, so merging would have shipped them; both are the same capacity/evidence-leak class the last four rounds have been closing. The remaining two (slotless rows escaping the per-user cap, and the non-rotating `started` reconciliation bucket) are genuinely latent and deliberately left alone. An UNPROJECTED PAUSE held a global capacity slot forever. The pause projection is what moves a run row off `started`; `recordScheduleOutcome` already retries it, but the request controller discarded the result, so three failed attempts were dropped silently. The armed engine's reconciler replays that state, but the clustered sweep did not: a paused job is not terminal, so the retained-job path returned without settling, and the dead-delivery path never inspects an identity-matched job at all. The row stayed `started` with no cutoff that would ever clear it. The call site now surfaces the failure, and the sweep converges it, mirroring the reconciler's pause branch: project `requires_action` (which frees the slot) but do NOT release the job's evidence — unlike a terminal job it is still live, awaiting an approval. The resume hand-off fence still defers, so re-projecting cannot release a slot a continuation just claimed. The BOOKKEEPING REPLAY pass leaked its retained job. A run reaches that pass only because its owner crashed before bookkeeping — which is also before it could release the job it retained for exactly this recovery. The active-run pass clears its own; this one never did, and a preserved job is deliberately kept WITHOUT `completedAt` so the store's finished-job sweep cannot reap it early, so nothing else ever would. It now clears after `finalizeBookkeeping` succeeds — identity-guarded, a no-op when no job is retained, and skipped entirely when the replay itself failed, since the retained job is the only surviving evidence in that case. Tests: pause projected and the slot freed while the live job's evidence is kept, paused job deferred during a resume hand-off, retained job released once replayed bookkeeping is durable, and retained job kept when the replay fails. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CZwZPDBgxy4mCWWg6zQSjq * fix(schedules): fence the clustered pause replay against a concurrent resume claim Codex round 5, on code I added in f735341. The finding is correct and the exposure is one I introduced. The pause replay lives in a sweep that runs in EVERY clustered replica, so several sweepers can observe the same unprojected pause. Its guards were all derived from an in-memory row SNAPSHOT: hasResumeHandoffInFlight reads the snapshot's resumeClaimedAt, and recordRunOutcome's pause branch matched any row currently in `started`/`requires_action` with no fence of its own. The race: sweeper A projects the pause and frees the slot; the owner's approval then claims a fresh one (markRunResumeClaimed takes the row to `started` WITH resumeClaimedAt in one write); sweeper B, still holding the pre-projection snapshot, passes its hand-off check and replays — `$unset: { capacitySlot, resumeClaimedAt }` under a continuation that is already running. The run reverts to `requires_action` while its generation proceeds outside global capacity. The engine's reconciler makes the same call and has the same snapshot-derived guard, but v1 arms exactly one engine, so it has no concurrent racer; the sweep is the first thing to run this transition in parallel. Left the engine alone rather than widening the change: its `requires_action` re-affirmation is deliberate and single-writer. Fixed where the race is, in the write itself. `recordRunOutcome` takes an optional `requireNoResumeClaim`, which adds `resumeClaimedAt: { $exists: false }` to the pause filter, and the sweep sets it. Because the stamp is written in the SAME update that moves the row to `started`, its absence is atomic proof no resume owns the row. The flag is deliberately NOT set by the generation owner: its own re-pause legitimately clears the stamp as the hand-off's completion signal. The fence cannot block the recovery it exists to enable: markRunResumeClaimed only matches `requires_action`, so a genuinely stuck `started` row can carry no resume claim — it is in fact blocking its own approval until this replay frees it. Tests: a replay from a stale snapshot leaves a resume-claimed row's status, slot, and claim stamp intact, while a stuck row with no claim still recovers; and the sweep is asserted to send the fence. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CZwZPDBgxy4mCWWg6zQSjq * fix(schedules): fence stale resume claims by age, not existence Codex round 6, on the fence I added in ee00c60. Correct again, and the defect is the mirror image of the one it fixed. The fence was an EXISTENCE check (`resumeClaimedAt: { $exists: false }`) while its caller's guard is a FRESHNESS check (hasResumeHandoffInFlight, bounded by RESUME_HANDOFF_STALE_MS). They agree while a claim is fresh and disagree once it is abandoned: a worker that dies after markRunResumeClaimed takes the row to `started` and stamps resumeClaimedAt — but before the continuation resumes or releaseRunResumeClaim rolls it back — leaves the stamp set forever. Past the bound the sweep correctly stops deferring and tries to recover the row, but the write rejected it purely because the field still existed. The row stayed `started` holding its global capacity slot, and its approval was unresumable for good, since markRunResumeClaimed only matches `requires_action`. That is exactly the stuck state this replay exists to clear, so the fence had reintroduced it for the crashed-resume case. `requireNoResumeClaim: boolean` becomes `resumeClaimStaleBefore: Date`, and the filter matches a row with no claim OR a claim older than that cutoff. The sweep passes the SAME bound its in-flight check uses, so the two can no longer disagree. A genuinely racing claim is by construction fresh — it is created after the sweeper's snapshot — so the race from round 5 stays closed. Tests: a row whose resume claim was abandoned by a dead worker now recovers (status, slot and stamp all cleared), alongside the existing two — a fresh claim still repels a stale-snapshot replay, and an unclaimed stuck row still recovers.

Replace `Array.prototype.at`, which the package target library does not provide.

Danny Avila	e7f1838515	⚡ feat: Reliable Interrupt & Steer Escalation and Recovery (#14558) ... * feat: surface interrupt-steer escalation on waiting messages The interrupt & steer feature shipped reachable only through the composer chord, the send-button hovercard, and the composer button; a message already waiting (queued for after the run, or steered and parked at the next tool boundary) had no path to it. Both waiting surfaces now carry one: - Queued rows get an icon-only ZapOff escalation button beside the existing Steer primary. It routes through sendQueuedNow, which now takes a preempt option on its live-run path. The tooltip teaches the composer chord, derived through resolveComposerKeyDown so a rebound or yielded chord is never advertised. - In-flight steer bubbles get an "Interrupt now" overflow entry with the same race rules as Edit: reclaim first, and only a `reclaimed` outcome resubmits (via retrySteer with preempt, swapping the chip for an interrupting one). `applied` and run-ended-mid-reclaim outcomes stop at the existing informational toasts, so the words can never land twice. Not offered on a steer already preempting. - Every during-run overflow menu gains an "Always interrupt instead" toggle for steerInterruptsByDefault, next to the existing steer/queue default toggle. MenuEntry supports disabled for the new entries. Only one interrupt can be unresolved at a time: while one preempt is pending (or the run is paused on approval, where the server 409s), every escalation control disables instead of racing the same seal. Ten new tests across both surfaces; 381 green in the affected suites. * fix: lock escalation across its reclaim window, keep the paused control visible, label as steer Codex round 1, all three findings. P2, escalation race. The single-interrupt invariant had a window between clicking "Interrupt now" and the reclaim resolving, where no preempt chip existed for the chip-derived gate to see: two bubbles escalated back-to-back could both resubmit. A shared escalating flag (Jotai, per-conversation) now covers the window and disables every escalation control on both surfaces, and a fresh recheck before resubmitting catches an interrupt armed elsewhere meanwhile (composer chord, queued row); those words re-home to the queue with an informational toast instead of breaking the invariant. P2, unreachable paused state. canSteer is defined as hasRealConvoId && !pausedOnApproval, so gating the button on canSteer removed it exactly when it was meant to render disabled; the test only passed on an impossible stub combination. The render gate is now duringRunActive && (canSteer || pausedOnApproval), and the test uses the real invariant. P2, label semantics. "Interrupt & send now" borrowed the name of the hard-abort action; this one preserves the partial answer and steers. Renamed to "Interrupt & steer now" (com_ui_interrupt_steer_now). Both behavior fixes counterfactually verified; 384 tests green across the affected suites. * fix: disable bubble escalation while the run cannot accept a steer Codex round 2, one P2. Answer mode (ask_user_question) sets duringRunActive false while pausedOnApproval stays false, since that flag only detects approval-bearing tool calls. The bubble's escalation entry stayed enabled there, so clicking it cancelled a healthy waiting steer and the preempt resubmission bounced off RUN_PAUSED, degrading the words to the queue. The entry now also disables on !duringRunActive, matching the queued-row control's gate. Counterfactually verified: reverting the gate fails the new answer-mode test. * fix: recheck live run state after the reclaim, not just at the click Codex round 3, one P2, and it is the round-1 recheck principle applied one level deeper: the entry-time disable cannot see a run that pauses (tool approval, answer mode) while the reclaim round-trip is in flight, and the .then closure held the render's stale steering controls, so the resubmit would fire into a RUN_PAUSED rejection after the reclaim had already surrendered the steer's boundary slot. The escalation continuation now reads the LIVE controls through a latest-ref: if the run can no longer accept a steer, the words re-home to the queue with an informational toast instead of resubmitting, and the resubmit itself also goes through the live controls. Counterfactually verified: reading the stale closure instead of the ref fails the new mid-reclaim pause test. * refactor: make escalation one atomic server-side arm, in place Codex round 4: four P2s, every one an interleaving of the same window — escalation as reclaim-then-repost is a compound, non-atomic operation whose continuation must revalidate the world (FIFO position lost, ref assigned too late, no run fence, competing bubble actions). Rounds 1-3 patched that window with a lock and rechecks; round 4 shows the window itself is the defect, so this removes it instead of guarding it again. Escalation is now POST /chat/steer/arm: the server flips preempt on the EXISTING queued item in one atomic store op (new IJobStore.armSteer; a decode-patch-encode LSET Lua on Redis, an in-place mutation in memory), fenced to the validated generation and refused once the queue closes. The handler mirrors the steer POST's preempt contract exactly: durable flag gated on the owner's recorded capability, volatile requestPreempt fire-and-forget because the durable flag is the truth resume/handover re-arm from. By construction this resolves all four findings: FIFO survives (the item never moves; the whole queue still drains in instruction order at the seal), there is no continuation to hold stale controls, the store op is fenced to the original run, and a competing Edit/Queue/Cancel either beats the arm (armed:false, chip untouched) or operates on the armed item, whose cancel already disarms. The client escalation entry becomes one mutation: armed:true relabels the chip in place (same steerId, same position), PREEMPT_UNSUPPORTED and lost races toast honestly, and the round 1-3 machinery — the escalating lock atom, the latest-ref, the post-reclaim rechecks and their two toast strings — is deleted rather than extended. Verified: 7 new handler tests on the real in-memory manager (including FIFO preservation and the stale-generation fence), 2 Redis integration tests against real Redis (in-place arm keeps order and every field; missing/stale/closed all refuse), client suites 396 green. * fix: decide capability inside the atomic arm, neutralize the lost-race toast Codex round 5, both findings, both edges of the new arm design rather than its mechanism. P2, capability TOCTOU. A HITL resume on a rolling deploy rewrites preemptCapable for the SAME generation, so the handler's read could go stale between validation and the flag flip, arming a steer the live owner cannot seal. armSteer now returns armed | missing | incapable, with the owner's live capability part of the same atomic predicate as the generation fence (HGET preemptCapable inside the Lua; the flat job field, not a metadata blob — the in-memory store reads the same field). The handler's pre-check is deleted rather than kept alongside; the store predicate is the single source. New handler test rewrites the capability after queueing and expects PREEMPT_UNSUPPORTED with the item left unflagged; the Redis guards test now asserts the incapable refusal against real Redis. P2, ambiguous toast. armed:false covers injected, cancelled, re-homed, and run-over alike, so telling the user the message "already reached the agent" claimed one specific outcome. The lost-race branch now uses a neutral message (com_ui_steer_arm_lost_race) and defers to the events for what actually happened. * fix: flip the escalation lock synchronously before the arm request Codex round 6, one P2. Round 4 deleted the escalating flag along with the reclaim continuation it guarded, but that left the one-interrupt gate blind during the arm request's own round trip: the chip-derived check cannot see an arm until its response relabels the chip, so on a slow connection two bubbles could both arm before either response landed. Double-arm is harmless server-side now (the run seals once and drains the whole queue in order), but every escalation control advertises "one interrupt at a time" by disabling, and the controls must tell the truth. The per-conversation escalating flag returns as a pure UX gate: set synchronously at click, before the mutation, cleared on settlement, and folded into interruptPending on both surfaces. Unlike its round 1-3 ancestor there is no continuation behind it to guard and no recheck to pair with it. Counterfactually verified: without the synchronous set, the two-bubble race test arms twice. 207 tests green across the Chat Input suites. * test(e2e): cover escalation of waiting messages through the real seal Three mock-harness tests on E2E_SLOW_REPLY, a 160-chunk stream with no tool boundary, so an in-thread steer part can ONLY come from a genuine mid-stream seal — which makes each test a behavioral proof rather than a UI check: - Queued row escalation: the ZapOff button turns a waiting queued message into a preempt-armed steer (202 echoes preempt: true) that seals and injects, where the sibling steering.spec test proves the unescalated path waits for run end instead. - Bubble in-place arm: an ordinary steer (202 with no preempt echo) waits as a bubble, POST /chat/steer/arm answers armed: true, the bubble relabels in place (same single bubble, same text, escalation no longer offered on reopen), and the armed steer seals mid-stream. - Always-interrupt toggle: flipped from a waiting row's overflow menu, plain Enter now produces a preempt: true steer that seals in the SAME run, and the menu offers the way back. An afterEach clears the localStorage preference so a mid-test failure cannot leak preempt-by-default into the rest of the serial suite. All three verified locally through the full harness (real backend, mock LLM, seeded DB): 3 passed in 27s. * feat: dedicated escalation arrow + shortcut, menu split into actions and preferences The escalation was still half-hidden: the bubble only offered it inside the overflow menu, and the tooltip taught the composer chord, which does a different thing (interrupts with typed text, not this chip). Three changes make it a first-class command: - A shared EscalateNowButton (circular arrow, ghost-bordered like the composer's interrupt control) is always visible on BOTH surfaces: beside each queued row's Steer primary and on every waiting steer bubble next to its menu. It disappears once a steer is interrupting. - A dedicated registry shortcut, escalateSteer (Cmd/Ctrl+Shift+.), editing-allowed and rebindable like every other action. Deliberately NOT an Enter chord: the composer owns every Enter chord, and the yield design rests on no default binding using Enter besides submit. Its handler clicks the newest enabled arrow control (bubbles beat queued rows), so the shortcut can never diverge from the button, and the arrow's tooltip teaches THIS command via the registry display. - The overflow menus separate one-off actions from sticky behavior changes: Edit, Cancel, Queue, then a smaller "Preferences" section holding the queueing and always-interrupt toggles, each with the standard InfoHoverCard reusing the Settings panel's descriptions. "Interrupt & steer now" leaves the menu entirely. 386 client tests green, including a menu-structure test locking the order and the absence of the escalation entry; bubble escalation tests drive the visible arrow. The e2e spec's bubble test now clicks the arrow, and a fourth test drives the dedicated shortcut end to end through a real mid-stream seal. * style: bind the escalation arrow to its message (variant A anatomy) Two same-weight circles in a row read as one control group, leaving the arrow's ownership ambiguous, and a floating arrow stops meaning anything once several messages stack. The shared control now carries variant A's anatomy: a thin divider binds a small SOLID arrow (filled, inverted) to the message region on its left, and the menu ellipsis stays a bare glyph, so the two affordances can no longer blur together — and the divider+arrow pairing repeats cleanly per chip at N messages. * chore: drop the unused within import CI lint caught * fix: advertise the escalation shortcut only while the control is live Codex on the e2e head, one P2: the tooltip appended the chord hint even while the button was disabled, advertising a shortcut that does nothing during an approval pause. The flagged control (InterruptNowButton) was since replaced by the shared EscalateNowButton, which inherited the pattern; the successor now omits the chord whenever the control is disabled, matching the rule the during-run hovercard already follows. * fix: harden steer escalation lifecycle and recovery * test(e2e): disambiguate accessible steer preferences * test: align abort persistence coverage with prerequisites * chore(i18n): remove obsolete steer race message * chore: normalize imports across steering changes * test: exercise stream integration on Redis Cluster * test: scope HITL checkpoints to generation * test: fix cluster cleanup and locale policy * fix: keep escalation visible during ask pauses * fix: fence recovery downgrade and stale predecessors * fix: require generation owner abort acknowledgement * fix: validate delayed preempt arms * test: align final escalation fixtures * fix: preserve in-memory predecessor abort handoff * fix: restore controls for recovered queued messages * test: cover recovered queue controls * fix: close final steering review gaps	2026-07-31 20:07:56 -04:00
Danny Avila	7bb6651883	🛑 feat: Preemptive Steer - Backend Interrupt & Steer (#14518) ... * 🛑 feat: Preemptive Steer — server half (Interrupt & Steer, PR 2 of 3) Lets the steer route ask the generating replica to seal its live model stream at the next provider-safe boundary instead of waiting for a tool step. The run is never aborted, job status never changes, the partial answer is kept, and generation resumes in the same assistant message after the injected steer. Consumes the SDK seam in @librechat/agents (danny-avila/agents#335, #346). Transport: IEventTransport gains a fenced emitPreempt/onPreempt pair beside abort. RedisEventTransport fans PREEMPT out on the SAME events channel and subscription (no new connection, key, or subscribe call); onPreempt returns a registration-scoped unsubscribe with the same replacement-safe state-identity guard onAbort uses. InMemory implements neither — single-process preempt lives entirely in the runtime set. Runtime state: RuntimeJobState carries the per-generation request set, createdAt-fenced and capped at STEER_QUEUE_MAX_DEPTH, plus a bounded `cleared` tombstone so a late cross-replica arm cannot resurrect a request whose steer already drained. registerPreemptSubscription mirrors the abort registration's double fence (runtime identity + generation createdAt); releaseAbortSubscription retires BOTH listeners and the armed set, so every terminal path drops preempt state for free. Public surface: requestPreempt (arm + fenced publish, never a rejection surface, never touches job status), isPreemptRequested (O(1) level-triggered poll), noteSteersRemoved (drain/cancel bookkeeping + fenced clear), clearPreemptRequests (empty-boundary disarm). One drain body, two boundaries: createSteerDrainHook (PostToolBatch) and createSteerPreemptBoundaryHook (PreemptBoundary) share drainAndBuildInjections, so the two injection sites cannot drift — the SDK's provider-safety argument rests on identical HumanMessage shapes. The shared body builds injections incrementally under a swallow-all catch (a mid-loop throw still injects what was applied — those parts are already persisted), clears preempt requests in finally, and disarms the generation when a boundary drains nothing. Request path: POST /chat/steer accepts preempt: true. The guard ladder is unchanged in order and in every status code. A preempt request is NEVER a rejection reason — without the capability the steer still enqueues and the 202 echoes preempt: false. Armed strictly after a successful enqueue; cancel disarms. The capability is read from the OWNING replica's recorded `preemptCapable` rather than the route replica's own SDK probe, so a rolling deploy cannot label a steer "interrupting" that the older owner will only inject at a tool step. Durable label: SteerQueueItem.preempt → TPendingSteer.preempt, so a parked/claimed/replayed chip keeps its wording. Run wiring: createRun registers the PreemptBoundary hook and threads RunConfig.preemption, both gated on isSteerPreemptSupported() — a separate probe from isSteeringSupported(), so the client affordance can never arm against an SDK that only injects at tool boundaries. buildSteerWiring builds both hooks from one shared closures object, so preemption survives HITL pause/resume for free. Honest finalization: an empty preempt boundary persists and emits with unfinished: true — the same contract an abort gets — re-marked explicitly because BaseClient has already saved the row as unfinished: false by that point. Not changed: no new job status, store method, Lua, SSE event type, endpoint, or authorization surface. abortJob, completeJob, transitionStatus, closeAndDrainSteers, getResumeState, emitChunk, applySteerPart and the whole abort path are untouched. Tests: 120 packages/api steering specs (preempt lifecycle, tombstone, fences, caps, terminal release, both-boundary drain parity, level-triggered poll, request/cancel arming, owner-capability degradation) plus 5 in api for buildSteerWiring gating, and 2 Redis-gated cross-replica transport specs. * 🔒 fix: Codex round 2 — evict tombstones, scope the empty-boundary disarm, honest resumes All four server findings were fresh consequences of the round-1 fixes, which is the review doing exactly what it should. - Tombstone cap refused new entries instead of evicting. Every drained or cancelled steer is tombstoned, not just preempting ones, so a generation that processed 20 steers exhausted the set and the late-arm race resurfaced silently. Now evicts oldest-first (Set iteration is insertion-ordered), with the budget named PREEMPT_TOMBSTONE_MAX rather than an inline expression. - The empty-boundary disarm I added in round 1 wiped the generation's ENTIRE armed set. A second steer can enqueue and arm between the atomic drain returning empty and the disarm running — that arm is backed by a live, uninjected queue item and must survive. The drain now snapshots the armed ids BEFORE draining (getArmedPreemptIds) and clearPreemptRequests takes an explicit id list instead of clearing everything. - HITL resume finalized with a hardcoded unfinished: false. The boundary hook is re-registered on resume via buildSteerWiring, so a resumed segment can end on an empty preempt boundary exactly like a fresh one; finalizeResumedTurn now reads getPreemptStats() and the halt reason, matching the normal request path. - Ownership moves on resume, so the job's recorded preemptCapable must describe the replica that will actually generate. Refreshed before resumeCompletion; a job created on a capable replica that resumes on an older one during a rolling deploy no longer acknowledges steers as interrupting. Tests: +3 (scoped disarm sparing a post-snapshot arm, oldest-first tombstone eviction, id-list disarm). 122 packages/api steering specs green. * 🚨 fix: Codex round 3 — deserialize preemptCapable from Redis (feature was dead under Redis) The P1 here is the most consequential defect in the whole feature, and it was introduced by round 1's own capability fix. - `RedisJobStore.serializeJob` writes booleans generically, so `preemptCapable` reached Redis — but `deserializeJob` is an EXPLICIT field map and had no line for it. Every `getJob()` therefore dropped the flag, `job.metadata.preemptCapable` was always undefined, and `handleSteerRequest` computed `preemptArmed: false` unconditionally. Interrupt & steer would have silently degraded to ordinary tool-boundary steering in EVERY Redis deployment — i.e. the feature shipping as a no-op in production while passing every in-memory test. Now deserialized, with a round-trip assertion in the metadata spec that fails (`Received: undefined`) against the unfixed store. - The resume capability refresh moved from just-before `resumeCompletion` to immediately after `approvals.resolve` claims the run. That call already flips the job back to `running`, so the steer route accepts requests from that instant; leaving the refresh 135 lines later (across the whole client reconstruction) left a real window where a steer read the PREVIOUS owner's capability. Not the fully atomic transition Codex suggested — that reaches into the approvals Lua — but it shrinks the window from seconds to one await, which is proportionate for a label-accuracy issue. Refuted: "avoid triggering preemption inside subagents". The premise — that the run-wide poll can seal a subagent stream — does not hold against the shipped SDK. Child graphs are constructed with `subagentScope: true` (SubagentExecutor) and `preemption` is NOT propagated into child inputs, while `canClaimPreemptSeal()` requires `!subagentScope && preemption != null`. Both conditions fail independently, so a subagent can never claim a seal and the boundary cannot fire with `agentId` set. The `input.agentId != null` guard in the hook is defensive depth, not the thing standing between us and the described failure. 140 packages/api specs green. * 🔁 fix: Codex round 4 — re-arm durable interrupt steers when resume moves owners - An arm lives only in the owning replica's runtime plus a transient pub/sub message, while the steer's `preempt` flag is durable on the queue item. A HITL resume landing on a different replica therefore started with an empty armed set and a poll stuck false, so an interrupt the user had already been ACKed for silently waited for an ordinary tool boundary. New `GenerationJobManager.rearmQueuedPreempts` rebuilds the armed set by peeking the durable queue (fenced on the generation) and re-arming every item flagged `preempt`; resume calls it right after claiming. Safe by construction: every item peeked is still queued, so no drained steer can be resurrected. - Capability-refresh failure now logs at error rather than warn, but deliberately does NOT fail the resume — see the reply on that thread. Tests: +2 (rebuild from queue arms only the flagged item and reports the count; a stale generation arms nothing). 124 packages/api steering specs green. * 📡 fix: Codex round 5 — acknowledge only what was actually armed - A cross-replica arm was fire-and-forget: `emitPreempt` logged its own publish failure and `requestPreempt` returned void, so the route answered `preempt: true` even when the owner never armed a poll. The steer still injected at the next tool boundary, but the chip claimed an interrupt that could not happen — and unlike HITL resume, an ordinary running generation had no durable reconciliation to recover it. `emitPreempt` now resolves to the subscriber count and rejects on failure; `requestPreempt` is async and returns whether the arm truly landed (owned locally, or delivered to at least one subscriber). The 202 reports THAT rather than what was asked for, so the chip relabels to ordinary steering exactly as it does for a capability-degraded deployment. Errors are swallowed into `false` — an unarmed interrupt is a downgrade, never a failed steer. - The owner capability is re-read immediately before enqueue rather than reused from the top of the guard ladder. `checkAgentAccess` and file resolution are awaits, so a request can span an entire HITL pause/resume that moves ownership to a replica with different capability and rewrites that very flag. Only paid for by requests that actually asked to interrupt. Tests: +3 (not-armed when the publish reaches nobody; armed when this replica owns the generation; a throwing publish downgrades instead of propagating). 127 packages/api steering specs green. * 🎯 fix: Codex round 6 — real ownership, confirmed disarms, and a CI regression of my own Three review findings plus three CI failures the round-5 commit caused. Review: - Ownership came from `runtimeState`, which a cross-replica `getJob` populates with a FACADE runtime on any replica that merely read the job. Matching `createdAt` therefore proved only "we looked at this job", so a non-owner could arm nothing and report success. Ownership now comes from `ownedJobs`, the actual owner map. - `armPreemptIds` returns how many ids it accepted, and a local arm is only reported as armed when one was. A tombstoned id (its steer drained at an ordinary boundary mid-request) no longer answers `preempt: true` for an interrupt that cannot happen. - The cancel disarm is awaited. A dropped clear is worse than a dropped arm: the owner keeps a level-triggered request for a steer that no longer exists, seals its next chunk and truncates an unrelated answer. The boundary drain's own call stays non-blocking — there the owner is local, so the disarm is already effective and awaiting the informational publish would only delay injection. - Subscriber count is NOT read as proof of owner receipt: the count includes this replica's own facade subscription. A successful publish reports armed, a rejected one does not. Documented rather than papered over — see the acknowledgement-semantics note on the PR. CI regressions from round 5, all mine: - `registerPreemptSubscription` was AWAITED at both runtime-init sites, so job creation blocked on a second Redis channel subscription and hung when that subscribe was slow. Abort is awaited because a missed abort strands a run; a missed preempt only degrades that steer to the next tool boundary, so it now registers without gating createJob. - Two api specs mocked `@librechat/api` without the newly imported `isSteerPreemptSupported`, so the call threw before createJob; and one exact-match assertion needed the new `preemptCapable` metadata field. - My own Redis integration spec asserted arm-before-clear ordering, which two publishes carry no guarantee of — the receiving tombstone exists precisely because of that. Now asserts delivery and payload fidelity, order-independent. 158 packages/api specs, 27 api specs green. * 🧭 fix: Codex round 7 — settle the acknowledgement semantics (Option A) Round 7's second finding is the incoherence I flagged on the PR: the route persisted `preempt: true` on the durable queue item while returning `preempt: false` when delivery could not be confirmed. Those two then disagreed, and `rearmQueuedPreempts` trusts the DURABLE one — so a resumed owner would honour an interrupt the client had explicitly been told degraded to ordinary steering. Rather than patch the disagreement, this settles the meaning: `preempt` in the 202 means "queued as an interrupt request", NOT "a seal is guaranteed". It mirrors `SteerQueueItem.preempt` exactly, so the response, the durable record, and the resume-time re-arm can never disagree. The gates that ARE knowable stay — the owner's recorded capability and a successful enqueue. Everything past that degrades to the documented fallback of injecting at the next tool boundary. A route cannot synchronously know whether another replica will seal: proving it needs a correlated request/response over pub-sub, and even that only proves the owner heard, not that it is still streaming when the arm lands. Four rounds of tightening this boolean each surfaced a narrower case; the sequence does not converge, so the invariant is now "the flag describes the durable decision" and an unconfirmed arm logs a warning instead of rewriting the answer. Also from this round: a failed disarm publish is retried once and its outcome reported. `handleSteerCancel` keeps `removed: true` — the steer really did leave the queue, and saying otherwise would make the client re-show a chip for a steer that can never arrive — and adds `disarmed: false` so the residual risk is visible rather than swallowed. Damage stays bounded regardless: the empty-boundary self-clear disarms the generation after a single seal. Tests: +1 pinning the response/durable-flag invariant. 159 packages/api specs green. * 🧹 fix: Codex round 8 — remove the unverifiable disarm signal Round 8 found the same over-promise on the disarm side that round 7 corrected on the arm side, so this applies the same answer rather than patching around it. The `disarmed: false` field added in round 7 was both unreliable and unused: a resolved publish is not proof the owner heard it (the delivery count includes this replica's own facade subscription), and it was never threaded into `CancelSteerResponse` or read by any client. A signal that claims a certainty the transport cannot provide is worse than no signal — it invites callers to trust it. Removed from the response. The retry stays, because it genuinely reduces the failure rate, and `noteSteersRemoved` still returns whether the publish succeeded FOR LOGGING, now documented explicitly as "published without error", not "the owner disarmed". Disarm is best effort with a bounded, self-healing failure: if the clear is lost the owner seals once, the empty-boundary self-clear disarms the generation, and the turn is persisted `unfinished: true` rather than silently truncated. Tightening that further needs a correlated request/response over pub-sub with a timeout — noted on the PR as the deliberate boundary of this design rather than an oversight. 130 packages/api steering specs green. * 🧽 fix: Codex round 9 — spend snapshot arms on nonempty drains too The round-6 scoping fix only cleared the pre-drain snapshot when the drain came back EMPTY. On a nonempty drain the `finally` cleared just the drained ids, so a stale arm — typically a cancel whose cross-replica clear was lost — survived the boundary. It would then immediately seal the continuation meant to answer the steer that had just been injected, and land on an empty boundary as `preempt_incomplete`: the interrupt appears to work, and the answer to it is truncated. A boundary that runs has spent its seal, so everything armed at snapshot time is spent whether or not it came back from the drain. The `finally` now clears the union of the snapshot and the drained ids. Arms that land AFTER the snapshot are still spared — their queue items are live and uninjected, which is the property round 6 added. Also fixes an api-workspace CI failure of mine: `resume.spec.js` stubs `GenerationJobManager` wholesale, and the round-3/4 resume work added two calls (`updateMetadata`, `rearmQueuedPreempts`) the stub did not define, so 34 specs threw. Stub extended. Tests: +2 (a nonempty drain clears a stale snapshot arm; a nonempty drain spares an arm that landed mid-drain). Counterfactually verified — the stale-arm spec fails against the unfixed drain. 132 packages/api specs, 60 resume specs green. * fix: never let a failed preempt subscription reject into the void registerPreemptSubscription is called detached at both sites, so a rejected Redis SUBSCRIBE became an unhandled rejection — process-fatal under Node's default --unhandled-rejections=throw. The comment already promised this path merely degrades steering; it now does. Swallowed and logged inside the registration rather than at each call site, so a future third caller cannot reintroduce the trap. Losing the channel costs this generation's cross-replica preempts, not the server: same-replica arming is runtime state and still works, and remote arms fall back to the next tool boundary. Verified counterfactually — the new spec surfaces SUBSCRIBE failed as an unhandled rejection against the unfixed registration. * docs: state the real blast radius of a failed preempt subscription LibreChat's own entrypoints install a global unhandledRejection handler that logs and keeps serving, so the escaping rejection this guards was never fatal to this server — only to another consumer of @librechat/api that installs no handler. The fix stands either way; the comment just should not overstate what it prevents. * test: cover the cross-replica preempt hop with two manager instances Every other preempt test runs against a single manager, so the hop that actually carries an interrupt in production had no coverage: the steer POST lands on whichever replica the balancer picks, which is usually not the one generating. Non-owner publishes, owner arms, owner's level-triggered poll flips — none of that was exercised end to end. Two GenerationJobManagerClass instances are a faithful replica pair here. runtimeState and ownedJobs are private instance fields, there is no module-level mutable state between them, and createStreamServices duplicates a dedicated subscriber connection per call, so separate OS processes would exercise the same objects over the same Redis. Both assertions verified counterfactually against real Redis: - Deleting the preemptCapable deserialization in RedisJobStore fails this with 'Expected: true, Received: undefined' — the exact P1 that shipped past every in-memory test and would have made the feature a silent no-op on every Redis deployment. - Dropping the non-owner arm publish fails it with 'Received: false'. * test: remove the fixed sleeps and vacuity from the cross-replica preempt test Codex round 11, both findings, both on the test I added last commit. P2 — the 300ms waits were load-bearing. Redis pub/sub never replays and the owner's SUBSCRIBE is detached, so on a slow CI worker the publish could land before anyone was listening and the test would fail against correct code. Now it republishes until the owner's state converges, which is safe because arms and clears are idempotent set writes keyed by steerId. Side effect: the tests got ~10x faster (85ms/57ms vs 929ms/606ms) since they finish on delivery rather than on a timer. P3 — afterEach destroyed only the transports, leaving each manager alive in its own cleanup-interval closure, still working against a dead transport. Now tracks the managers and awaits destroy(), which disposes the job store and its timer too. Matches how the rest of this file cleans up. Fixing the sleeps exposed a third problem codex did not flag: the stale-arm test could pass vacuously, because an undelivered arm and a fenced one look identical. It now brackets the stale publish between two control arms — the first proves the owner is listening before the stale one is sent, the second proves it has had its chance to arrive. Verified counterfactually against real Redis, and stable over 5 runs: - dropping the preemptCapable deserialization fails with 'Received: undefined' - dropping the non-owner arm publish times out both tests - removing the generation fence fails the stale test with ["control-before", "steer-stale", "control-after"] — which also confirms the bracketing orders as intended rather than by luck * fix: gate interrupt on the OWNER's capability alone, not the route's Codex round 12. The comment above this gate already said 'the OWNER's recorded capability, not this replica's probe' — and then the code ANDed in isSteerPreemptSupported(), which is exactly this replica's probe. The contradiction dates to the original commit; round 6 made the gate owner-scoped and wrote that comment without removing the local conjunct. The route never seals. It enqueues and publishes an arm, neither of which touches the SDK, so during a rolling deploy a steer landing on an un-upgraded replica silently lost its interrupt even though the owner could seal. When the route IS the owner the probe is redundant anyway: the flag it would consult is the one this process wrote at createJob. The real degradation path is unchanged and still tested — an owner that recorded no capability relabels to an ordinary steer. The test that pinned the local probe asserted an impossible same-replica state (capable metadata plus an incapable local SDK, when the metadata is written from that probe); it now pins the mixed-SDK direction instead, and fails with 'Expected: true, Received: false' if the probe is put back. * fix: reconcile arms at handover, and stop holding the 202 on a publish Codex round 13, two of three findings. P2 — rearmQueuedPreempts only ever ADDED. A replica that merely read the job still installs a facade runtime and subscribes, so it can accept an arm and then miss the best-effort clear that follows the drain. HITL resume promotes that facade to owner, the union keeps the orphan, and the first resumed stream seals on a steer no longer in the queue, drains nothing, and truncates the resumed answer as preempt_incomplete. acquireResumedJobOwnership only sets ownedJobs, so nothing else was clearing it. The durable queue is the sole authority at a handover: arms it does not back are now disarmed and tombstoned, so an in-flight publish cannot revive them either. Worth recording that my own independent review raised this and my verifier refuted it. Codex found it separately; two reviewers converging should have outweighed one refutation. P2 — the route awaited the arm publish before answering. The 202 reports capability, not delivery, so the await could not change the response; it only exposed the caller to Redis latency after the queue item was already durable. A client that times out and retries mints a second steer while the first stays queued, injecting the same instruction twice, whereas a lost publish merely takes the tool-boundary fallback. Detached, with both outcomes logged. All three tests verified counterfactually: union-only rearm fails the two new handover specs, and re-awaiting the publish hangs the stalled-publish spec until jest kills it. * fix: snapshot arms before reading the queue at handover Codex round 14 — a regression from my own round-13 fix, and a worse failure than the one it corrected. Round 13 read the durable queue first, then tombstoned any armed id the snapshot did not back. But approvals.resolve reopens steering before reconciliation runs, so another replica can commit a preempt steer and publish its arm while the peek is in flight. That arm is then present locally but absent from a snapshot taken before the steer existed, so a LIVE interrupt the route already acknowledged got dropped — and tombstoned, which blocks the re-arm, making it unrecoverable rather than merely late. Fixed by inverting the two reads rather than by locking or paying a second round trip. A steer is durably enqueued BEFORE its arm is published, so any id in an arms-first snapshot was already queued when it was armed, and the later peek must observe it unless it has since drained — which is exactly the orphan this reconciliation exists to drop. Arms landing after the snapshot are simply not candidates. Also re-checks runtime identity across the await, since the generation can be replaced while the queue read is in flight. New spec injects a steer + arm during the peek and verifies it survives; against the round-13 ordering it fails with Received array: []. * fix: bound the cancel disarm wait and fence enqueue to its generation Codex round 15. P2 — the cancel awaited its disarm publish unbounded. ioredis queues commands during an outage rather than rejecting, so that await could hang for the length of the outage with the steer ALREADY durably cancelled; a client that gives up then treats the cancel as failed and restores a chip for a steer that can never produce an applied event. Every successful cancel publishes, so ordinary steers were exposed too, not only preemptive ones. Now bounded at 1s, with the publish continuing behind it — its retry and logging are unchanged, it is just no longer in front of the response. This is the sibling of round 13's arm-publish finding; I fixed one path and left this one. P3 — enqueue was not fenced to the generation the capability decision was made against. The access checks, file resolution and owner re-read are all awaits, so the run can be replaced before the enqueue: the item then lands on the REPLACEMENT queue while the durable preempt flag and the arm still name the previous epoch, the arm is fenced out at the owner, and the 202 promises an interrupt that cannot happen. enqueueSteer now takes an expected generation, mirroring drain/peek, and the Redis path enforces it inside STEER_ENQUEUE_LUA so the check is atomic with the push rather than racing it. All three new specs verified counterfactually, including the Lua guard against real Redis (removing it returns 1 where -1 is required). * fix: fence the steer to its authorized generation, bound resume setup, keep preempt when Redis parks Codex round 16, all three findings. P2 — round 15 fenced the enqueue to owner.createdAt, the RE-READ job. Every guard above it (ownership, tenant, paused-state, agent ACL) ran against the job read at the top, so if the run was replaced during those awaits the fence happily accepted the steer into a generation the request was never authorized against, carrying the wrong agent's metadata. Now rejects on any mismatch between the validated job and the re-read. P2 — resume awaited its steering bookkeeping unbounded, after approvals.resolve had consumed the action and flipped the job to running, and outside the resume lifecycle's own try/finally. .catch does not fire on a promise that never settles, which is what ioredis produces during an outage, so the client times out, its retry gets a 409 for a spent action, and no cleanup runs. Bounded at 1s with the writes finishing in the background. P3 — Redis parks leftover steers inside its terminal-transition Lua, which projects item fields one by one, so preempt was silently dropped and a steer recovered from /chat/status lost its interrupting label. Added to both projections. All three verified counterfactually, two against real Redis. Worth recording that my first version of the generation-mismatch test was VACUOUS — it faked a createdAt matching no live job, so the round-15 enqueue fence rejected it for the wrong reason and the test passed with the guard removed. Rewritten to replace the run for real; it now fails with 'Expected 404, Received 202'.	2026-07-30 12:36:13 -04:00
Danny Avila	7b6900d556	🏷️ feat: Activity Groups With Fast-Model Headers (#14391) ... * ✨ feat: Activity Groups with Fast-Model Labels Groups each contiguous block of reasoning + tool calls into a collapsible unit headed by a fast-model label (claude.ai-style hierarchy), off the critical path: a PostToolBatch hook claims a live content slot at the batch boundary (steering index-offset pattern), renders a deterministic counts phrase instantly, and swaps in the generated label ~1s later while the next model call streams. Labels are UI-only — stripped before the SDK formatter and skipped in the legacy formatter — and reach live clients via a dedicated on_activity_label SSE event (live/replay/pending paths). Grouping preserves legacy rendering byte-for-byte when no label part is present. Generation bridges to Run.generateActivityLabel() when the SDK ships it (session-grouped Langfuse tracing); falls back to a direct call today. Env-gated: ACTIVITY_LABELS_POC=true, ACTIVITY_LABEL_MODEL. * 🧷 fix: Address Codex and Copilot Review Findings for Activity Labels - Settle in-flight label fills (bounded 3s) before finalization on both the main and resume paths, so a label resolving during the final batch still reaches the durable log and saved message. - Overlay on_activity_label chunks in RedisJobStore content reconstruction (splice path last-wins per index; replay path chronological overwrite), matching steer handling. - Wire activity labels into the HITL resume createRun so post-resume batches keep claiming slots. - Guard against out-of-order publishes: fill() awaits the claim emit before emitting the resolved label, and the client applier ignores a stale pending placeholder once a resolved label is present. - Stamp the batch's groupId onto label parts so parallel-column runs place them inside their group instead of filtering them out. - Localize the counts fallback phrase (10 keys, singular/plural) through useLocalize across chat rendering and exports. - Type the hook with Providers/ClientOptions instead of stringly types; drop the unknown cast in the spec; add a dedicated rAF retry ref for label events with effect cleanup. * 🛡️ fix: Address Independent Review — Abort, Usage, Lane Context, Redis Test - Propagate the run abort signal into label generation (both wiring call sites; runtime combines host + dispatch signals with the timeout) so a user abort cancels in-flight label calls instead of paying to timeout. - Record label-call usage like titles: the SDK bridge aggregates via chainOptions callbacks, the fallback path via a per-generation callback factory; both feed recordCollectedUsage under context 'activity-label'. - Scope block-context capture: reasoning collection stops at the previous block's label part and filters by executingAgentId, so consecutive or parallel batches can no longer bleed another block's thinking into the payload; intent text still scans past labels (persists across batches). - Forward the effective charLimit to the SDK call so host and SDK prompts agree (SDK default aligned to 600 in agents#327). - Add a Redis integration test proving last-write-wins reconstruction of on_activity_label chunks per claimed index. - Rebased onto main: only the two activity commits replay (the nine steering commits belonged to the old base branch), zero conflicts, steering suites green. * 📐 refactor: Move Activity-Label Wiring to TypeScript, Address Codex Round 2 - [P1] Slot claiming, lane stamping, emit ordering, context capture, and settle tracking now live in packages/api (createActivityLabelWiring + captureActivityBlockContext); client.js is a thin closure wrapper. - Register the activity-label hook BEFORE the steer drain so a steer draining at the same batch boundary cannot flush the tool block and orphan the label outside its group. - Resolve request-based header placeholders in resolveActivityLabelLLM (titleConvo parity) so metadata-keyed proxies work on label calls. - Trim labels centrally before filling so whitespace-only output from either generation path keeps the deterministic counts fallback. * 🧭 fix: Codex Round 3 — Capture Order, Shared Strip, Token Estimator, Hide Filter - Capture block context BEFORE pushing the label part: the scan stops at ACTIVITY_LABEL parts, so post-push capture hit the just-inserted label and silently collected no reasoning excerpts (regression test added). - Share stripActivityLabelParts from packages/api and apply it in the Responses and OpenAI-compatible controllers, closing the replay leak for entry points still running SDKs without the formatter skip. - Exclude activity_label parts from the fallback response-token estimator (UI-only parts must not inflate no-usage provider billing). - Keep label parts explicitly under hide_sequential_outputs — they summarize exactly the outputs that mode hides. * 🔁 fix: Codex Round 4 — Resume Gap, Delta Flush, Agent-Scoped Intent, Token Counter - Synthesize on_activity_label events for labels claimed or filled in the snapshot→subscribe window (the publish is fire-and-forget, so Redis-mode reconnects missed them). Feature-gated so the default path adds no content re-read; the client applier already ignores duplicates. - Flush queued deltas before applying a label part, matching the pending- action and steer appliers — without it the handler read a stale message cache and syncStepMessage pushed a pre-delta copy back. - Skip another agent's tail text when resolving intent, so parallel runs cannot seed a label prompt with a sibling agent's narration. - Exclude activity_label parts from countFormattedMessageTokens (the agent-path counter), not just the legacy BaseClient one. * 🏗️ refactor: Codex Round 5 — Extract Label Host Logic, Report Usage, Icon Strip - Move provider/model resolution, usage-metadata mapping, and the settle loop into packages/api (activityLabels/host.ts); client.js keeps only thin delegations, per the repo's TypeScript-implementation convention. - Fold label usage into the response rollup with an 'activity-label' tag (subagent precedent) so metadata.usage and the live cost gauge account for it; tagged, so it stays out of PRIMARY usage/context pairing. - Narrow tool metadata once in ToolCallGroup so THINK parts in a labeled block no longer render phantom generic icons in the stacked strip. - Import the activity-label helpers by deep path in GenerationJobManager: the package barrel now reaches provider-config/cache modules that import back into the stream layer, and the cycle broke suite loading. Declined: resetting steerOffsetState before HITL resume — resume builds a FRESH AgentClient via initializeClient (initialize.js:978), so the offset is already zero; the seed wrapper alone accounts for pre-pause parts. * 🚦 fix: Codex Round 6 — Stream Label Usage, Close Late Fills - Emit an on_token_usage chunk for label calls (sink push alone left the live session gauge blind); retained in pendingSubagentEmits so job cleanup cannot race the persist, tagged 'activity-label' as before. - Close the label scope when settle times out: the wiring gates fill() on isClosed and the client fires a label-scoped AbortController, so a straggling generation can neither mutate a saved response nor emit into a job whose runtime is gone. The controller also chains to the run signal, so a user abort still cancels label work. * 🩹 fix: Repair CI — Package Typecheck and Module Mocks Local runs covered the client tsconfig and jest, but never packages/api's own tsconfig, so nine type errors in the extracted host module shipped. - Type host.ts against the real contracts: ServerRequest, EndpointDbMethods, AppConfig from @librechat/data-schemas, IUser for createSafeUser, and a MaybeAzureConfig view for the azure instance-name probe and configuration. - Widen resolveConfigHeaders' llmConfig to Partial<RunLLMConfig>: it only reads the three provider header carriers, so auxiliary generations with a bare ClientOptions can resolve headers without assembling a run config. Type-only widening; every existing caller still satisfies it. - Add stripActivityLabelParts to the @librechat/api mock in the OpenAI and Responses controller specs — those mocks enumerate exports, so a new import read as undefined and threw before the assertions ran. - Use the real activity-label helpers in the ToolCallGroup spec's ~/utils mock; stubbing them out would hide the header logic under test. * ⚙️ feat: Configure Activity Labels via librechat.yaml, Drop Env Vars Replaces the ACTIVITY_LABELS_POC / ACTIVITY_LABEL_MODEL env gate with per-endpoint settings, following the title options convention rather than a top-level block — each endpoint picks its own cheap label model. - Add activity, activityModel, activityEndpoint, activityPrompt, activityMaxPerRun, and activityCharLimit to the endpoint schema, and to the endpoints.all pick list (enumerated, so 'all:' would otherwise drop them silently). - resolveActivityConfig reads them with title-style precedence: endpoints.all > named endpoint > custom endpoint config. - Model precedence is now activityModel > titleModel > the agent's model. activityEndpoint runs labels on another endpoint's credentials, with titleConvo's fallback-on-unknown-name behavior. - Thread activityPrompt/MaxPerRun/CharLimit through the wiring into the hook and the SDK bridge; they were hardcoded defaults. - The resume gap-repair gate keyed on the env var; it now keys on the snapshot actually containing label parts, so deployments without the feature still perform no extra content read. - Document the fields in librechat.example.yaml; add host.spec.ts covering precedence, custom-endpoint fallback, and opt-out. * 📝 refactor: Rename Enable Flag to activityLabel, Document Schema Inheritance - Rename the boolean from `activity` to `activityLabel`, matching the titleConvo/titleModel shape: a verb-object toggle whose prefix matches its modifiers (activityModel, activityPrompt, ...). `activity: true` alone read ambiguously — it could mean tracking or logging activity. - Document the two endpoint-schema inheritance paths, which behave oppositely and are ~900 lines apart: * `endpoints.all` omits from baseEndpointSchema, so new options are inherited automatically — nothing to maintain. * `azureEndpointSchema` enumerates via .pick(), so a new option is silently unavailable on Azure endpoints until listed there. The activity block now carries a pointer to the Azure caveat. * 🔍 fix: Address Codex Findings on the Config Rework - Pass the matched custom-endpoint config into the label gate. Custom endpoints live in the `endpoints.custom` ARRAY, so without it every custom endpoint resolved as disabled — including the example this PR added to librechat.example.yaml. - Give label usage a unique `runId:seq`. Label usage is billed but never appended to `collectedUsage`, so its length was static: every label event reused the last primary usage's pair and collided with itself, and the client dedupes on exactly that. - Attach `cost` to label usage when `interface.contextCost` is on; aggregateEmittedUsage treats coverage as all-or-nothing, so an event without it suppressed the whole response's cost. - Honor `activityPrompt` on the direct fallback path, not just the SDK bridge — it previously always used the built-in instruction. - Seed the per-response label cap from labels already on the response so a HITL resume cannot mint a fresh quota after every approval. - Reconcile label gaps on resume via a durable per-job `activityLabels` flag instead of probing the snapshot: the FIRST label of a run can be claimed inside the snapshot->subscribe window, which the old signal missed. The flag is read from a job record already fetched there, so runs without the feature still add no content read. - Auto-collapse labeled single-tool groups; one-call batches are common in agent runs and rendering them expanded defeats the grouping. * 🎯 fix: Correct Label Usage Seq, Cross-Endpoint Pricing, Close Scopes - Give label usage a NEGATIVE seq namespace. The previous fix was wrong: seq is a position in `collectedUsage` (push, then emit with the new length), so sink-length + array-length still lands on a real position — primary emits 1, the label computes 2, the next primary also emits 2. Labels have no position at all (billed separately, never appended), so they now occupy a namespace positional sequences cannot reach. The client key is a string used for Set membership, so the sign is inert. - Price cross-endpoint labels with the LABEL endpoint's token config: resolveActivityLabelModel now returns the resolved endpointTokenConfig, and both the streamed cost and recordCollectedUsage use it instead of the agent endpoint's rates. - Make close state per-wiring rather than per-client. A HITL resume rebuilds the wiring, and resetting a shared flag re-opened closures from the pre-pause segment whose provider call ignored the abort; settle now closes every retained scope, past generations included. * 🎯 fix: Make the Activity Header Say Something the Cards Cannot The header read "ran 1 command" next to a card already labeled "Code" — it restated the UI beneath it instead of adding to it. Two causes, both about content rather than timing: - A deterministic tool-type tally was the primary display and also fed the prompt, so the best case was a tally and the worst case was a tally dressed as prose. Removed from the metadata, the prompt, the part type, and the client. - The instruction only ever reached the fallback path. The wiring passed a prompt only when was configured, so the preferred SDK path silently used the published package default. The wiring now always supplies one and the hook forwards it on both paths. The register is rewritten around what the cards cannot show: past-tense git-commit-subject, leading with the distinctive noun, outcome over attempt, tool names and counts and arguments explicitly forbidden. The batch entries are labeled as reference material so the model stops transcribing them. Claiming a slot no longer emits. The slot still reserves its index so streamed parts never collide, but with nothing to say there is nothing to render: until a description exists the block looks exactly as it does without the feature. * 🧹 fix: Drop the Localize Hook Left Unused by the Counts Removal * ✅ test: Add Activity-Label e2e Coverage with a Recording Label Server Activity labels are the one model call a mock run does not already fake: fake-model.js swaps the GRAPH model via overrideTestModel, while run.generateActivityLabel() calls the endpoint resolved client options over HTTP. The custom endpoints already point baseURL at 127.0.0.1:8889, so serving that port exercises the real path with no production seam. fake-label-server.js answers it in both JSON and SSE form, records each prompt, and can inject blank/error responses. Recording is what lets the spec assert the CONTRACT rather than the rendering: that this repo register and the tool OUTPUTS actually reach the model. That is the bug class that produced unusable labels before, and rendered text looks identical whether or not the instruction arrived. Labels get a dedicated endpoint (Mock Provider E). A labeled block auto-collapses even at one tool call, which hides the tool cards other specs assert on -- enabling this on a shared endpoint broke steering.spec.ts. Provider D is the unlabeled control. Request-count assertions are scoped to a per-test token: a 5xx label response is retried by the provider client, and a retry can land after the next test has reset the server. * 🩹 fix: Address Review Findings on Activity-Label Indexing and Pricing Replay index (P1). Reserving the slot only in server memory left no event for it, so a cross-instance replay rebuilt content as [tool, hole, later], compacted the hole away, and the fill for the reserved index landed on the following part and overwrote it. The claim now publishes the empty, pending part so the index is real for every consumer, and fill publishes even when generation returned nothing so the client cannot stay pending. It stays invisible: an empty label still DELIMITS its batch in groupSequentialToolCalls but is not attached as the header, so grouping does not re-shuffle when the text lands and the block renders exactly as it does with the feature off. Edited-response index (P1). Edit-and-resubmit replays the kept prefix and the server indexes only new content, so run steps offset by that prefix. Labels are claimed in the same space and now take the identical shift; without it a label could land inside the prefix and overwrite it. Redis flag. deserializeJob never read activityLabels back, so every Redis reload left it undefined and resume skipped label gap reconciliation. Executing agent. RunActivityLabelOptions.agentId selects the executing agent tracing metadata AND its tool-output redaction policy; omitting it let a handoff be redacted under the default agent configuration. Label pricing. An undefined endpointTokenConfig is meaningful for a built-in label endpoint (priced from the shared table), so the nullish fallback billed those labels at a custom primary rates. Inherit only when the label runs on the agent own endpoint. HITL usage sequence. runId is the response message id and the counter was instance-local, so a resume restarted at -1 and the client runId:seq deduper discarded the post-approval label usage. Seeded past the labels already on the response. Also distinguishes "cannot serve" (undefined) from "no label" (null) in the SDK bridge, so a missing run falls back to the direct call instead of filling the slot empty. Version gating already happens at wiring time via the sdkCapable prototype probe. * 🩹 fix: Keep Unfilled Activity Labels Invisible and Unmask Endpoint Settings Follow-up review round. Publishing the reservation on every batch made two latent rendering paths reachable on every run, and both are fixed here. Empty labels no longer change grouping. The previous pass still formed a tool-group for a textless label, which wrapped even a single tool call and pulled THINK parts inside it — and since a reservation is published the moment each batch ends, that applied during every generation and permanently after a blank or failed fill. An empty label now flushes the legacy way instead: it still delimits its batch, but the block re-splits exactly as it renders with the feature off. Parallel lanes no longer show a blank line. Lanes render raw parts, so an unfilled label had nothing to draw; empty ones are dropped. Making labels act as collapsible headers inside lanes is still a separate gap. Edited responses no longer offset on resume. The sync replaces initialResponse.content with the server's aggregatedContent, which already contains the kept prefix AND everything generated since — so its length is not the prefix length, and indices reconciled from that snapshot are already absolute. Offsetting again pushed the label past its slot onto a later part. The shift now applies only to a fresh edited submission. Activity settings resolve field by field. Selecting one config object whole meant any endpoints.all block — even one carrying nothing but headers — shadowed the named or custom endpoint and silently disabled activity labels everywhere. Global still wins per field. Adds groupToolCalls coverage for the invisible-while-empty contract, which is the part most likely to regress: it is normal state on every run, not an edge case. * 🔒 fix: Scope Detached Label Writes to Their Generation Epoch Epoch scoping (P1). Label generation is detached and can outlive the generation that started it. emitChunk only proves that SOME runtime is current, not that the caller belongs to it, so an aborted generation's fill(null) -- and its usage event -- could be attributed to whichever generation replaced it, landing an index from the abandoned response on top of the new one. Because an empty label renders nothing, that overwrote content silently. emitChunk now takes an optional jobCreatedAt and drops the event when the runtime epoch differs, mirroring the existing setGraph/setContentParts convention, and both label emitters pass it. An abort now CLOSES the label scope instead of only cancelling the call: the rejected generation still runs its catch and calls fill(null), which would otherwise emit into a stream the next generation may already own. Edited-response indexing (P1). The previous pass skipped the prefix offset on resume, which was the wrong half of the problem: a sync replaces initialResponse.content with the server's aggregatedContent, which is completion-local, so after a reconnect its length is not the kept-prefix length and the offset is wrong -- but it is wrong for run steps in exactly the same way. Tool cards and the label that heads them must share one index space; a label shifting differently from its tools lands on another part. The label path now uses the identical expression as useStepHandler, with no resume special-case. Correcting the post-resume prefix length belongs in calculateContentIndex, where it fixes both at once. titleModel masking. The activity settings were made per-field last pass, but the titleModel fallback a few lines below still selected an entire config object, so a partial endpoints.all (for example one carrying only headers) hid a named endpoint's titleModel and quietly fell the label back to the main agent model. Both now read through one shared per-field helper. Resume reconciliation no longer depends solely on markActivityLabels, which is best-effort yet had come to gate correctness: a lost flag write silently dropped a label. The snapshot is consulted as a fallback. The exported host type for generateLabel now admits undefined, which is the documented "cannot serve, fall back to the direct call" signal the hook keys on -- distinct from null, meaning it ran and produced nothing. * 🧷 fix: Keep Group Identity Stable and Memoize Label Endpoint Resolution Group remount. Tool-group identity was keyed on the first part in the block. An activity label absorbs the block's leading THINK part the moment its text lands, so the key flipped from tool:<id> to fallback:<scope>:<idx> mid-run, remounting the group and discarding whatever the user had expanded. The key now scans for the first tool call, which does not move when the block re-forms. Label endpoint resolution is memoized per response. It reads provider config and can hit the database for user keys, yet nothing it depends on changes between batches of one run — and it ran twice per batch, once for generation and once for usage accounting. The promise is cached rather than the value so concurrent batches share a single in-flight resolution, and a rejection is evicted so one transient credential failure cannot disable labels for the rest of the response. * 🎯 fix: Offset Edited Resubmissions by a Prefix Length That Survives Resume The server indexes only NEW content for an edited resubmission, so the client offsets incoming indices by the prefix it retained. That prefix was read as initialResponse.content.length, which is correct only until a resume: the sync replaces that array with the server's completion-local snapshot, whose length is unrelated to the prefix. After a reconnect every offset was therefore wrong -- run steps and activity labels alike -- and could write over content the edit kept. For a label the symptom is worse than a bad position: the fill misses its own reservation, so the pending placeholder is never resolved. The prefix length is now captured when the submission is built, while initialResponse.content still IS the retained prefix, and carried on the submission as editPrefixLength. calculateContentIndex takes that length instead of deriving it from an array that a resume may have replaced, so run steps and labels share one index space by construction rather than by both happening to read the same field. Note the prefix is the FULL original content with the edited part substituted in place (useChatFunctions clones latestMessage.content and mutates one entry) -- it is not a slice, so the length cannot be inferred from editedContent.index. Group identity no longer changes when a label fills. Tool-group keys were derived from the first part in the block; an activity label absorbs the leading THINK part when its text lands, flipping the key mid-run and remounting the group, which discarded the user's expansion state. The key now scans for the first tool call, which does not move. Label endpoint resolution is memoized per response. It reads provider config and can hit the database for user keys, yet ran twice per batch -- once to generate, once for usage accounting -- while nothing it depends on changes within a run. The promise is cached so concurrent batches share one in-flight resolution, and rejections are evicted so a transient credential failure cannot disable labels for the rest of the response. The resume gap passes for steers and activity labels now share a single lazy content read instead of each issuing its own. The label pass stays gated on the run flag with a snapshot fallback: reconciling unconditionally would also close the residual first-label window, but it would bill a read to every resume of every run, including deployments with the feature off -- which the steer pass deliberately avoids. That residual requires a lost flag write, which shares fate with the content writes the labels live in. * 💵 fix: Bill Cross-Endpoint Labels at Their Own Rates recordCollectedUsage never accepted an endpointTokenConfig, so the value the activity-label caller passed was dropped and the balance transaction was written at the primary agent's rates. Only the UI cost honored the label endpoint, so a custom primary pointing activityEndpoint at another endpoint showed one price and charged another. The parameter is now accepted, and an explicit config wins outright over per-agent resolution: that map is keyed by AGENT, so it cannot describe usage that ran on a different endpoint. Group identity is stable for id-less tool calls too. The previous pass anchored the key to the first tool call ID; where a supported tool call carries no id the fallback still used the block's first part index, which shifts when a filled label absorbs the leading THINK part. The fallback now anchors to the first TOOL entry's index, so only a block containing no tool call at all keys off parts[0]. markActivityLabels is retried rather than fire-and-forget. It gates resume gap reconciliation and is a SEPARATE write from the durable label append, so a single lost write silently drops a label the content itself recorded. The earlier "shared fate with content writes" reasoning was wrong. One retry at run setup costs nothing and removes the only realistic way the gate goes stale, without billing a content read to every resume. * 🧮 fix: Stop Offsetting Once SYNC Drops the Edited Prefix The edit offset was applied unconditionally, but whether it is correct depends on which branch SYNC took. SYNC either preserves the content already loaded for the response -- which still contains the retained prefix, so the offset is required -- or replaces it with the server's aggregatedContent, which is completion-local and indexed from zero, after which any offset writes past the end of a now shorter array. That is why the two previous attempts each fixed half of it: skipping the offset on resume was right for the replace branch, applying it unconditionally was right for the preserve branch, and neither holds on its own. The offset now tracks the actual state of the rendered content. For an activity label the replace branch was worse than a bad position: the fill landed past its own reservation, so the pending placeholder was never resolved and the block kept its generic header for the rest of the run. Applied to run steps as well, not just labels. useStepHandler reads the prefix from the same submission and had the same unconditional offset, so after a mid-session resume of an edited response tool cards were misplaced too. Normalizing at the dispatch boundary keeps both in ONE index space by construction: a label that shifted differently from the tools it heads would land on another part. Note the reload path was already coherent -- useResumeOnLoad rebuilds the submission without editedContent or editPrefixLength, giving no offset against server-supplied content -- so only the mid-session SYNC path was inconsistent. * 🧾 fix: Keep Label Accounting Out of the Primary Usage Slot Label usage no longer owns getStreamUsage(). recordCollectedUsage assigned its result to this.usage unconditionally, so when the primary provider reported no usage metadata but the label provider did, BaseClient took the label's output tokens as the assistant response's authoritative count. The later primary call returns early on an empty collectedUsage and never replaced it, so the wrong value stood, the text-based fallback was skipped, and the real generation went unbilled. Secondary usage is still billed but no longer writes that slot. Cross-endpoint pricing keys off an explicit discriminator rather than the presence of a value. A built-in label endpoint prices from the shared table, so an undefined endpointTokenConfig is its MEANINGFUL value -- reading that as "no override" fell back to the primary's custom rates and restored the exact mismatch the previous pass set out to fix. The caller already knows whether the label ran elsewhere and now says so. markActivityLabels rejects on failure instead of swallowing it. The flag gates resume gap reconciliation and the caller retries it, but the internal catch resolved successfully and made that retry unreachable -- so the two changes cancelled out and a transient write failure still left the flag absent. Late label accounting is suppressed with the same gate as the late fill. A straggler that outlived the settle timeout still ran its finally block, so it charged the balance and appended to usageEmitSink after the response had passed its usage flush and metadata snapshot: a cost the user pays but is never shown. The cleared-prefix state is scoped to one generation. It was set on a resume SYNC that replaced the response and then never reset, so a later edited resubmission in the same mounted hook dispatched run steps and labels with no offset against content that still held its retained prefix. Reconnects pass isResume and keep the state; a new generation clears it. * 🔑 fix: Key Prefix State to the Stream and Honor current_model for Labels The cleared-prefix reset keyed on isResume, which skips exactly the case it was added for: a submission whose POST succeeded server-side but lost its response is retried, comes back resumed: true, and subscribes in resume mode even though it is a NEW generation. A previous generation's cleared state then survived into it, and incoming run steps and labels applied no offset against content that still held its retained prefix. The state is now keyed to the stream id, which changes with the generation and stays put across reconnects of one. activityModel now honors current_model. The options are documented as title-shaped and the titleModel fallback already excludes the sentinel, but the higher-precedence activity override passed the literal string through to getOptions and the provider, so an endpoint following that convention failed every label instead of using the agent model. * 🎯 fix: Key Prefix State to the Generation and Resolve the Run Model The cleared-prefix state was keyed to the stream id, which never changes within a conversation: request.js sets streamId = conversationId, so once a reconnect cleared the state every later edited resubmission in that conversation dispatched run steps and labels with no offset and could overwrite the prefix it retained. It is now keyed to the response message id, the only per-generation identity available here -- minted per submission and carried through a resume unchanged. That is the third identity tried for this state. isResume missed the deduplicated-retry path (a lost response returns resumed: true for a new generation); the stream id is conversation-scoped. The response id is the boundary that actually matches a generation. current_model labels now resolve the model the run is really using. initializeAgent merges the request's endpointOption override into model_parameters and the run gives it precedence, so preferring the saved agent.model could send labels to a different, potentially unavailable or more expensive model than the conversation is on. * 🆔 fix: Key Prefix State to the Submission and Keep the Origin Title Model Editing an assistant response reuses that response's messageId as editedMessageId, and useChatFunctions carries it onto initialResponse.messageId -- so re-editing the same response produced two generations with the same key and the cleared-prefix state survived between them, leaving run steps and labels with no offset against content the edit retained. Keyed now to clientRequestId, the per-submission uuid, which is minted fresh per edit attempt and forwarded unchanged on retries. That is the fourth key this state has had, and each earlier one failed at a real boundary: isResume missed the deduplicated-retry path, the stream id is the conversation id, and the response message id is reused across edits of one response. clientRequestId is the identity that actually means "this submission". The titleModel fallback is read from the ORIGINATING endpoint again, matching how titleConvo captures its config before switching credentials. Reading it after an activityEndpoint switch meant an OpenAI endpoint configured with titleModel claude-haiku and activityEndpoint anthropic fell through to the OpenAI run model and sent that name to Anthropic, failing every label. The destination endpoint supplies credentials, not the model choice. * 🧷 fix: Close the Remaining Edit, Epoch, and Scope Gaps for Labels SYNC clears the edit prefix on the new-row branch too. When a resumed edited submission cannot match an existing assistant row, that branch builds the response straight from the server's completion-local aggregatedContent, so it holds no retained prefix -- but the reset lived only in the matched branch, leaving later steps and labels adding an offset to indices that were already absolute. Label usage is keyed per GENERATION. Editing one assistant response reuses its responseMessageId while each fresh generation restarts activityLabelUsageSeq, so a second edit re-emitted the same runId:seq and the client discarded the newer usage while its balance transaction was still written. The key now carries jobCreatedAt, the run's own epoch: stable across reconnects and HITL resumes, distinct between generations. The scope is revalidated at commit time. Checking once before the await let a scope that closed mid-flight still charge the balance after finalization, while the matching fill saw the closed scope and dropped the label -- billed but never surfaced, the exact outcome the guard exists to prevent. The titleModel fallback no longer reaches the destination endpoint. With activityEndpoint set and no titleModel on the originating endpoint, it picked up the destination's, so changing only the credential target silently changed the model and its cost. Precedence is activityModel, then the originating endpoint's titleModel, then the run model; the destination supplies credentials only. * ✂️ refactor: Confine the Edit-Prefix Offset to Activity Labels useStepHandler is now byte-identical to dev again. The resume-aware prefix offset was applied there too, which was more correct in principle -- the post-resume prefix length is genuinely wrong for run steps as well -- but it changed index math that EVERY run step flows through, for every user, including everyone who never enables activityLabel. That shared correction needed five revisions in two days (isResume, the stream id, the response message id, clientRequestId, and the SYNC new-row branch), each passing the full suite and each failing at a boundary only review found. Carrying it inside an opt-in feature put every user behind logic with that track record. It belongs in its own change, with tests that construct the edit-plus-resume states none of the current suites reach. The offset now applies only where the label handler places its part, so this PR cannot alter rendering for anyone with the feature off. The known consequence is recorded in the description: with activity labels ENABLED, an edited response that reconnects mid-generation can place its label and its tool cards in different index spaces. That is a bug for opt-in users rather than a regression for everyone, and it disappears once the shared fix lands. submission.editPrefixLength stays: the label path still needs a prefix length that survives a SYNC replacing initialResponse.content. * 🧾 fix: Commit Labels Before Billing and Keep Blank Slots Invisible Round-nine review (all P2, feature-scoped): - Billing ordering (client.js:409, runtime.ts): usage accounting ran BEFORE the slot commit on both generation paths, so the settlement deadline could expire during the balance write — charged, then the fill dropped as out-of-scope: billed, never shown. `slot.fill` now resolves a commit flag, generators register their accounting via `deferUsage`, and the hook runs it only after a committed fill. - Scope gates (client.js:757): the direct-fallback `collect` omitted `scopeOpen`; both paths now gate on the OWNING wiring's scope, so a pre-pause straggler cannot bill because the resumed generation's scope is still open. - Blank-label grouping (groupToolCalls.ts:81): a blank slot forced a flush, splitting adjacent single-call batches into standalone cards where the feature-off path merges them. Blank labels now only mark the claim boundary — structurally invisible, while a later filled label still cannot claim an earlier batch. - Stale fill indices (wiring.ts:301): the skill-card unshift and the hide-sequential filter reshape contentParts before the finalization settle, so an in-flight fill emitted its claim-time index against a shifted array. Both completion paths now settle label fills before any post-run content reshaping (the finally settle stays as the error-path net; the second call sees an empty pending list). - Bounded serialization (runtime.ts:238): `JSON.stringify` fully materialized unbounded tool results to keep 200/600 chars per entry. A budget-bounded serializer stops at the limit (which also bounds cyclic values) and preserves the exact truncate-with-ellipsis output. Tests: fill/bill ordering + suppression on dropped fills (runtime.spec), blank-slot merging and claim boundaries (groupToolCalls.test), bounded serialization equivalence and giant-output truncation (runtime.spec). * 🧮 fix: Keep Deferred Label Billing Inside the Settle Window Self-review follow-up to the billing reorder: deferring usage until after the commit moved it PAST the fill's resolution, so a settle keyed on fills alone could let finalization flush the usage sink and snapshot metadata while the label's billing was still in flight — the usage row would silently miss the message rollup even on the happy path. The hook now reports its whole detached task (generate → fill → deferred usage) via a `trackTask` option, wired to the same settle tracker as the fills, so finalization waits for billing exactly as it did when accounting preceded the fill. The task never rejects. Pinned in runtime.spec: the tracked task resolves only after usage collection. * 🧰 fix: Harden Label Resolution, Output Bounds, and Cache Billing Round-ten review (all P2, feature-scoped); the sixth finding is the documented edited+reconnect index-space limitation, answered on-thread as deliberately out of scope for this PR. - Rejected-LLM memoization (runtime.ts): the hook cached a rejected `resolveLLM()` promise permanently, failing every later batch and silently defeating the host resolver's own rejected-cache eviction. The memo now evicts on rejection so the next batch retries. - `current_model` precedence (host.ts): an explicit `activityModel: current_model` resolved to `undefined` and then lost to a configured `titleModel`. The sentinel now resolves straight to the run model; the title fallback applies only when `activityModel` is absent. - Output bounds (runtime.ts): label text was persisted verbatim; a model ignoring the 4–9-word instruction (or steered by injection in untrusted tool output) could emit thousands of tokens duplicated through SSE, the chunk log, persistence, and the UI. `normalizeLabelOutput` keeps the first non-empty line, collapses whitespace, and hard-caps at 200 chars on both generation paths. - Cache-token billing (host.ts, client.js): the usage mapper dropped cache fields, vanishing Anthropic cache tokens from billing and charging OpenAI cache reads at the full input rate. The mapper now normalizes Anthropic/OpenAI/LangChain cache shapes into `input_token_details`, and the emit + cost path carries them with the label endpoint's `provider` (additive-provider adjustment). - Usage-type union (runs.ts): `TTokenUsageEvent.usage_type` now includes the emitted `activity-label` literal; the lone consumer keys on `usage_type != null`, so this is type-level completion. Tests: sentinel/title/explicit model precedence and all three cache shapes (host.spec), transient-resolution retry and output normalization with truncation (runtime.spec), the new usage literal (runs.spec). * 🪗 fix: Let Settled Labels Collapse Void Tools and Keep the Tail Cursor Round-eleven review (all P2, client-side). Two fixed; the other two findings restate documented Known limitations (edited+reconnect run-step index space; parallel-lane collapsible headers), answered on-thread. - Void-tool auto-collapse (ToolCallGroup.tsx): `allCompleted` keyed solely on output truthiness, so a tool that legitimately returns an empty string kept its labeled group expanded forever. A settled, filled label is itself a completion proof — the PostToolBatch claim only happens after every output in the batch returned — so it now satisfies `allCompleted`; pending labels keep the group live. - Trailing-reservation cursor (ContentParts.tsx): a blank label reservation at the content tail renders nothing but still counted as the last part, stripping the streaming cursor and last-item affordances from the last VISIBLE part until the next delta. `lastContentIdx` now walks back past empty label slots. Tests: labeled void-tool group auto-collapses, pending-label group stays expanded (ToolCallGroup.test). * 💳 fix: Price Label Cache Correctly, Honor endpoints.agents, Cancel Every Retry Round-twelve review: four fixed here; the remaining P1 (move the client.js bridge into packages/api) is an architecture call answered on-thread for the maintainer. - Provider on billed entries (client.js, P1): round ten added cache details to label usage entries but not `provider`, and `splitUsage` treats an unknown provider as additive — re-adding cache_read and cache_creation on top of an input count that already contains them, double-charging Anthropic/OpenAI cached label calls while the streamed cost (which carried the provider) disagreed. Every mapped entry now carries the label endpoint's provider. - endpoints.agents honored (host.ts, client.js): `initializeAgent` rewrites `agent.endpoint` to the backing provider, so activity settings under the PUBLIC `agents` endpoint — valid config, inherited by `agentsEndpointSchema` — were silently ignored. Field resolution is now `all` > public endpoint > backing provider/custom, applied to both the enable gate and the model/titleModel resolution. - E2E_LABEL_PORT reaches the YAML (playwright.config.mock.ts): an overridden port moved the fake label server and its health check but not the generated config's hard-coded 8889 baseURLs, so readiness passed while every label request targeted the wrong port. The override is now substituted into the generated copy. - Every retry frame cancelled (useResumableSSE.ts): concurrent label retry chains (reservation + fill per slot) overwrote one rAF handle, so cleanup cancelled only the newest chain; the rest ran up to 120 frames past unmount and could apply a stale label to a replacement generation reusing the same response id. Outstanding frame ids now live in a Set that cleanup drains. Tests: public-endpoint gate/precedence/all-above-public (host.spec). * 🖱️ fix: Keep the Last-Part Cursor in Parallel Lanes Too Round-thirteen review (single P2): `ParallelContentRenderer` computed `lastContentIdx` from the unfiltered array, so a trailing blank label reservation — filtered out of every lane — left NO rendered part carrying the last-part cursor and running-subagent affordances until the label filled. The sequential renderer's walk-back is extracted into a shared `lastVisibleContentIdx` helper (utils/activityLabels) used by both `ContentParts` and `ParallelContentRenderer`, so the two index spaces cannot drift again. Behavior pinned in activityLabels.spec: trailing blank skipped, consecutive blanks skipped, filled label counts, label-free content unchanged. * 🧹 chore: Alias the Retry-Frame Set for the Effect Cleanup Lint Rule * 📏 fix: Let activityCharLimit Reach Tool Inputs Round-fifteen review: `activityCharLimit` is documented as the per-entry truncation for tool input AND output, but `buildPrompt` hard-coded inputs at 200 characters — so raising the setting could never surface a distinguishing path, query, or operation that appears past the first 200 characters of a long argument. Inputs now truncate at the configured limit alongside outputs; the 200-char constant remains only for the intent line (renamed INTENT_CHAR_LIMIT to match). Config fidelity pinned in runtime.spec: a 400-char argument survives a 450 limit and truncates under a 50 limit. The round's other finding is the fifth restatement of the documented edited+reconnect index-space limitation, answered on-thread with the prior four cross-references. * 🤝 fix: No Labels for Pure Handoff Batches Round-sixteen review: a PostToolBatch containing only `transfer_to_*` calls claimed a label slot, but transfer parts are never groupable — the client flushed the handoff card standalone and the label orphaned into a stray line after it, restating what the card already says. Two-sided fix: - Hook (runtime.ts): a batch whose every entry is a transfer call claims nothing — no slot, no model call, no `maxPerRun` consumption. Mixed batches still label (the header describes the real work). - Renderer (groupToolCalls.ts): an orphan label whose `tool_call_ids` are all transfer calls is dropped instead of rendered standalone, covering content persisted before the hook-side skip. The round's two P1s are repeats answered on-thread: the packages/api extraction (maintainer-decided follow-up, recorded in the description) and the sixth restatement of the edited+reconnect index limitation. Tests: transfer-only batch claims nothing, mixed batch still claims (runtime.spec); transfer-only orphan label dropped, real-batch orphan label still renders (groupToolCalls.test). * 🎛️ fix: Sanitize Label Client Options and Bound the Batch Prompt Round-seventeen review: two fixed; the other two findings repeat the maintainer-decided packages/api extraction (follow-up) and the edited+reconnect index limitation (seventh instance), answered on-thread. - Primary-option strip (host.ts): the label client copied the resolved `llmConfig` wholesale, so an endpoint whose defaults enable extended thinking or carry model-specific output caps forwarded them to the (often cheaper) label model — unsupported options failed every label, and supported thinking spent real tokens and the settlement window on a 4–9 word header. The copy now strips `omitTitleOptions` keys and the `modelKwargs` output caps exactly like the title path, restoring the Anthropic `clientOptions` carrier by reference so proxy `defaultHeaders` still reach label requests. - Batch prompt budget (runtime.ts): per-entry truncation left the batch dimension unbounded — hundreds of parallel calls could build a prompt past the fast model's window. The entries section now has a total budget (8k chars, scaling with `activityCharLimit` so a raised limit still fits several entries); entries past it are skipped without paying their serialization cost, and the list notes how many were omitted. The first entry always renders in full. Tests: option strip with header-carrier survival (host.spec); giant batch bounded with omission marker, small batch untouched (runtime.spec). * 🛡️ fix: Keep SSRF Guards on Label Calls, Skip Mixed Handoff Batches Round-eighteen review: four fixed; the fifth repeats the maintainer-decided packages/api extraction (eighth instance), answered on-thread. - SSRF-safe carrier (host.ts, P1): the sanitize step restored the Anthropic `clientOptions` carrier only when `defaultHeaders` existed, but for user-provided base URLs `getLLMConfig` stores the guarded Undici dispatcher and `redirect: 'error'` there — dropping it reopened DNS-rebinding/redirect paths on label calls to user-controlled URLs. The carrier (client CONSTRUCTION options, not generation params) is now restored whenever present, same reference. - Primary maxTokens (host.ts): top-level `maxTokens` is not in `omitTitleOptions` and survived the strip; the title path deletes it explicitly, and a cap sized for the primary model can be rejected by the substitute. Deleted on the copy. - Bounded keys (runtime.ts): the object branch materialized every key via `Object.keys` and quoted oversized keys in full before the budget check. Enumeration is now lazy (`for..in` + own-property guard) and keys slice to the budget before quoting, like string values. - Mixed handoff batches (runtime.ts, groupToolCalls.ts): the client flushes the block at the transfer card, so a mixed batch's label orphaned exactly like a pure one. The hook now skips ANY batch containing a transfer call, and the renderer drops orphan labels covering one (legacy content). Tests: carrier survival without headers by same reference, maxTokens strip (host.spec); mixed batch claims nothing (runtime.spec); mixed orphan dropped, real-batch orphan kept (groupToolCalls.test). * 🧢 fix: Cap Label Generation, Order the Flag Persist, Detach Settled Listeners Round-nineteen review: three fixed; the fourth is the ninth instance of the edited+reconnect index limitation, answered on-thread. - Generation cap (host.ts): stripping the primary output caps left label calls with NO cap at all — `normalizeLabelOutput` bounds what persists, not what the provider generates and bills, so a model ignoring the 4–9-word instruction (or steered by injected tool output) could emit its provider-default output per batch. The sanitize step now installs a 256-token label cap (per provider family: `maxOutputTokens` for Google-style wrappers, `maxTokens` otherwise), after the filter so the omit set cannot remove it. - Flag-persist ordering (client.js): the `markActivityLabels` write was fire-and-forget, so an immediate cross-replica reconnect could read the job between the write and the first claim, see neither flag nor snapshot label, and skip gap reconciliation. Label emission now awaits the (settled-on-failure) persist chain, making "a label event exists" imply "the flag is durable" — the race window is gone; only the documented double-write-failure residual remains. - Listener detach (client.js): each HITL approval cycle's wiring adds a `once` abort listener to the shared job signal that only an actual abort removes; settled segments now detach theirs in `settleActivityLabels`, so long multi-approval runs cannot accumulate dead closures toward the listener-limit warning. Tests: the primary cap is REPLACED by the 256-token label cap (host.spec). * 🎯 fix: Route the Label Cap Per Model Family Round-twenty review: the 256-token label cap set maxTokens unconditionally, but GPT-5+ rejects max_tokens (the OpenAI builder routes its cap into modelKwargs.max_completion_tokens / max_output_tokens) and o-series models reject it with no stable kwargs alternative — every label on those models would have failed. The cap now mirrors the builder: modelKwargs for GPT-5+ (responses-API aware), no cap for o-series (title parity; the 200-char persistence bound still applies), maxOutputTokens for Google, maxTokens otherwise. Pinned in host.spec for both reasoning families. The round's other finding is the tenth instance of the documented edited+reconnect index limitation, answered on-thread. * ⏱️ fix: Persist the Label Flag at Run Start, Not on the Emit Path Round-twenty-one review: two fixed; the other three repeat the maintainer-decided packages/api extraction, the edited+reconnect index limitation, and the parallel-lane header limitation — all answered on-thread with their standing decisions. - Flag ordering, corrected (client.js): sequencing label emission behind the flag persist (previous round) delayed the claim-time reservation while the shared index offset had ALREADY shifted subsequent SDK chunks — reopening the cross-instance hole-compaction overwrite the reservation emit exists to prevent. The reservation emits immediately again; instead, run start (processStream and resume alike) awaits the settled-on-failure persist chain, so the flag is durable before any batch can claim a label. Same guarantee, zero latency on the emit path. - Tail-label cursor (ContentParts.tsx): a filled label at the content tail is consumed into the group header rather than listed in `group.parts`, so the `isLast` check missed it and nothing held the streaming cursor until the next delta. The check now includes `labelPart.idx`. * 🔌 fix: Detach Label Abort Listeners Even Without Claims A segment with labels enabled can end without a single claim (text-only, or handoff batches, which skip labels); the early return in settleActivityLabels skipped the detach added for HITL listener accumulation. The detach now runs on both paths. * ⚖️ fix: Make the Commit Flag the Sole Billing Authority Round-twenty-three review: a committed fill racing a late scope close (user abort or settle timeout during the durable emit) stayed visible — the part is mutated and persisted before the close — yet the deferred accounting's scope gates then skipped the charge: a completed provider call escaping both the label charge and the primary abort accounting. The scope gates on the deferred-usage path are removed; the hook's commit flag is now the single billing authority in BOTH directions. A dropped fill never reaches the accounting callback (billed-never-shown stays impossible), and a committed fill bills regardless of when its scope closed (shown-never-billed now impossible too). The dead `scopeOpen` payload threading is removed with it; the `recordActivityLabelUsage` parameter survives, defaulting open, for callers that own no commit signal. The round's other finding is the twelfth instance of the documented edited+reconnect index limitation, answered on-thread. * 🧮 feat: Bill Labels by Estimate When Providers Omit Usage Maintainer decision: follow the title convention rather than leaving label calls unbilled when a provider returns no usage metadata. The hook now passes a LAZY estimate thunk with the deferred accounting on the success path — the EXACT prompt the direct path sent (or the locally built equivalent for the SDK path: same entries, context, instruction, truncation contract, and continuity headers) plus the final normalized label. `recordActivityLabelUsage` invokes it only when no collected entry carries a real token count, counts both texts with the shared o200k_base tokenizer, and feeds the synthesized entry through the SAME pipeline (provider-tagged, streamed event, cost, balance transaction). Real provider usage always wins when present. The failure path passes NO estimate: a throw before a response bills only real collected metadata, never a full phantom prompt. Tests: the estimate thunk carries the exact invoked prompt and final label; the failure path defers with no estimate (runtime.spec). * 💵 fix: Estimate From the Raw Completion, Not the Normalized Label The fallback estimate counted the normalized label (first line, 200-char cap) while the provider generated and would bill the raw output up to the 256-token generation cap — under-recording verbose replies. The estimate thunk now carries the raw pre-normalization text; the persisted label is unchanged. Pinned with a multi-line reply test. * 🧾 fix: Commit Label Text Only After the Durable Emit, Estimate the Real SDK Prompt Round review on the billing work: two fixed; the third is the fourteenth instance of the edited+reconnect index limitation, answered on-thread. - Copy-first fill (wiring.ts): the fill mutated the shared content part BEFORE its durable emit, so a failed emit left the label text on `contentParts` anyway — persistence could save and display a label no client ever received and billing (keyed on the commit flag) never charged. The new state is staged on a copy; the shared part mutates only after the emit succeeds, so content, delivery, and billing move together. - Real SDK prompt for estimates (client.js): the estimate thunk carried this module's locally built prompt, but the SDK path frames entries differently — the estimated input count was for a prompt never sent. Chain-start callbacks (handleLLMStart/handleChatModelStart) now capture the prompt the SDK actually rendered, and the deferred accounting substitutes it into the estimate when capture succeeded, falling back to the local approximation otherwise.	2026-07-29 14:05:47 -04:00

Danny Avila	9e245aced4	🎟️ fix: Claim Idempotency Keys to Dedup Retried Generation Requests and Prevent Double Billing (#14344) ... * 🐛 fix: Dedup retried start-generation requests to prevent duplicate billing A lost or reset start-generation response makes the client re-POST the identical payload (up to 3x on network errors). The resumable-stream controller had no idempotency: createJob unconditionally overwrote the running job without aborting the prior one, so both requests ran full LLM completions and both billed while the UI showed only one (#14339). Add a stable per-submission clientRequestId (uuid, fresh per ask() so a regenerate differs, reused across the start-generation retries) and an atomic claim on the job store keyed by userId:clientRequestId. The first request wins and generates; a retried POST loses the claim and receives the original stream, which the client subscribes to and replays - no second billed generation. - IJobStore.claimIdempotencyKey/releaseIdempotencyKey (in-memory Map+TTL, Redis single-key SET NX PX + GET Lua, cluster-safe) - GenerationJobManager.claimGeneration/releaseGeneration (20m TTL) - Controller claims before the concurrency check, dedups with a resumed response, releases on start-failure/429 - clientRequestId threaded through TSubmission/TPayload/createPayload * 🐛 fix: Harden start-generation dedup (Codex review) Address three P2 findings on the idempotency path: - Resume replay: a deduped retry now subscribes with resume=true so the client replays prior content and any pending-action from the running stream instead of only live events (cross-replica / HITL correctness). startGeneration returns { streamId, resumed } and the response's status:'resumed' drives the subscribe mode. - Wait for the job record: a duplicate that loses the claim now waits briefly for the winner to create the job before returning the stream (a stream with no job 404s terminally). If the winner has not materialized, return 503 SERVER_NOT_READY so the client retries via the existing readiness path instead of attaching to a dead stream. - Release only owned claims: track whether the request actually won the claim; the 429 and init-error paths no longer release a claim owned by another in-flight generation (fail-open path could erase it and re-enable double billing). Adds controller tests covering dedup, the 503 race fallback, win-then- create, and claim-release ownership on 429 / fail-open. * 🐛 fix: Don't trap deduped retries on missing job records (Codex review) The previous round returned 503 SERVER_NOT_READY when a deduped retry's job record was absent. But a missing job usually means the original generation already completed and was cleaned up (cleanupOnComplete) — the correct recovery is to return the stream and let the client's subscribe 404 handler refetch the persisted messages. The 503 instead trapped the send in a readiness-retry loop until the client's window expired. Keep the bounded wait (it still covers the job-about-to-be-created race) but always return the resumed stream afterward; a gone/never-created job recovers via the client's existing 404 path instead of being treated as indefinitely starting. Updated the controller test accordingly. * 🐛 fix: Gate deduped resume on claim age, not just job presence (Codex review) Removing the 503 entirely (previous round) reintroduced the inverse race: if the winning request stalls between claimGeneration and createJob, a losing duplicate saw no job, returned status:'resumed' anyway, and the client subscribed to a stream that did not exist yet — the 404 handler tore the turn down while the winner went on to generate and bill with no UI attached. Distinguish the two missing-job cases by claim age (claimedAt now travels on the claim value): - fresh claim, no job yet → winner is still starting → 503 SERVER_NOT_READY so the client retries via the readiness path (bounded, not indefinite). - old claim, no job → the original already completed and was cleaned up (or the winner died) → attach; the client's 404 handler refetches. Tests cover both age branches. * 🐛 fix: Scope dedup fail-open + keep resumed convos on 404 (Codex review) - Fail-open only on claim acquisition: a store error while checking an already-confirmed existing claim no longer falls through to createJob (which would start a second billed generation during a Redis hiccup). Once claim.existing is known, a job-lookup error returns 503 retry. - Don't drop a resumed convo on 404: the optimistic-conversation cleanup in useResumableSSE now runs only for fresh (non-resume) subscribes. A deduped resume whose original completed and was cleaned up 404s, but its conversation is persisted and must stay in the sidebar. Adds a controller test for the job-lookup-error path (503, no createJob). * 🐛 fix: Reconcile resumed convos on 404 instead of guessing (Codex review) Round-4's !isResume guard fixed the completed-and-cleaned case (don't drop a persisted convo) but left the inverse: a new-conversation retry deduped to a claim whose original worker died before persisting still resumes, 404s, and — with removal skipped — leaves a phantom /c/<streamId> sidebar entry. Stop guessing keep-vs-remove on a resume 404. Reconcile against the server: invalidate the conversations list so a real (persisted) convo stays and a phantom is dropped. Fresh (non-resume) optimistic streams still prune immediately. Adds a client test for the resume path. * 🐛 fix: Finalize failed job before releasing its claim (Codex review) In the initialization-error catch, the idempotency claim was released before completeJob(streamId). A racing retry could win the released key and createJob() the same streamId while this catch was still running, and completeJob() (not guarded by the original createdAt) would then abort the replacement. Finalize the failed job first, then release the claim. Adds a controller test asserting completeJob precedes releaseGeneration. * 🐛 fix: Clear claims on destroy + survive completeJob failure (Codex review) - InMemoryJobStore.destroy() now clears the idempotencyClaims map, so a reused/reconfigured store instance doesn't dedup a fresh start against a torn-down job's stale claim. - Init-error cleanup: completeJob() is swallowed so a store-hiccup rejection can no longer skip the idempotency-key release and the pending-request decrement (which would wedge the retry behind the claim and leak the concurrency slot). A failed completeJob finalized nothing, so releasing afterward still can't abort a later replacement. Tests: claims cleared on destroy; release + pending decrement still run when completeJob rejects.	2026-07-21 08:16:31 -04:00
