fix(server): cancel approval-blocked tools when runs end - #22982
Approval-blocked Claude commands can remain running after a runtime-mode change fails their run. The shell then keeps showing Running commands and Stop even though those calls never executed. Addresses #22957.
Change
Finalization now emits cancellation events for run-owned command/dynamic-tool items that are still pending or have a waiting approval child backed by a pending runtime request. Their linked approval request, node, and item settle in the same batch, and stale approval responses reject. Accepted approvals and unrelated running/confirmed background work stay untouched. Server SQL/replay and the shared web/desktop/mobile reducer preserve cancellation through late active updates.
Scope limits: existing stale historical rows are not repaired, and approval-blocked file-change items are excluded. #21935 shares stale-approval symptoms but its Stop/delegated-cancellation path is not fixed here: it terminalizes the run before this finalizer can run. No full coverage of that issue is claimed.
Verification
This uses the event side rather than filtering the pending-shell query: stored item state must agree for shell/Stop, thread projections, and other consumers. The orchestrator remains pure and the shell query is unchanged.
Verification:
Before the fix, the fake-Claude server harness failed both approval assertions: the failed run retained a running item and the SQL shell snapshot still selected it. Background and completed controls passed.
Final head 661329512e65c3a08adabdad89cf0ddacdec9625: both proof auditors independently reran the targeted server/client files, 28/28 passed (9 server integration cases, 19 shared client projection cases). Earlier wider server verification: 101 passed. Scoped server/client typechecks and lint passed (three existing server lint warnings).
Identical final tests against four production files restored to main 680152e27b: 11 failed / 17 passed. Five server regressions and six client guards fail; background/completed/accepted/unlinked controls pass. The incident case reaches successor completion/checkpoint readiness before detecting the originals still running.
Cases cover pending approvals, Auto mode change, failed-run finalization and follow-up dispatch; confirmed background, completed, accepted approval, unrelated running/pending approval, dynamic tools, stale approval rejection, and late updates.
Independent Codex and Claude code reviews: MERGE after addressing their findings. Independent final proof audits: both SUFFICIENT for the harness mechanism.
The final incident case has two separate approvals, mode change plus dispatch before failure, successor command/run/checkpoint completion, then a fresh SQL shell snapshot. Query-close events are simulated using a Deferred latch; queue.resume is explicit. This does not establish live adapter timing or automatic successor resumption.
Harness verification only: cannot-verify claude live. No composer screenshot or live Claude claim.
Leave DRAFT; dispatcher certifies CI and decides readiness.

loadRunOwnedTools passes a ProjectionStore operation through a service input as an Effect-returning callback. Could RunExecutionService acquire ProjectionStoreV2 from its layer environment and load the projection itself during finalization? This keeps the new persistence dependency explicit in the service requirements rather than injecting it through the caller. The fix spans the service layer and its caller, so there is no self-contained suggestion here.

An approval accepted after loadRunOwnedTools() reads this snapshot is overwritten as cancelled, losing the accepted decision and potentially causing its response effect to fail. dispatchRuntimeRequestRespond leaves the run running, so writeIfRunCurrent() still passes, and the runtime-request upsert does not guard against replacing a resolved request. Revalidate the request/tool state atomically with the cancellation write, or condition cancellation on the request still being pending.

Summary
Load run-owned tools and cancel pending work apps/server/src/orchestration-v2/ProviderTurnStartService.ts, apps/server/src/orchestration-v2/RunExecutionService.ts, apps/server/src/orchestration-v2/TerminalShellItems.integration.test.ts
Root-run startup passes a loader to finalization. Finalization cancels eligible tools and linked approval requests, nodes, and turn items across covered termination paths. The integration test covers approval states, pending and unlinked shell items, and provider failure.
Finalization writes enable a guard that filters stale approval-request cancellations and associated node and turn-item events. Both event-write paths apply the guard when enabled.
Preserve cancelled items in projections apps/server/src/orchestration-v2/ProjectionStore.ts, packages/client-runtime/src/state/orchestrationV2Projection.ts, packages/client-runtime/src/state/orchestrationV2Projection.test.ts
Server persistence and client state retain cancelled command-execution and dynamic-tool items when later updates report active states. Client tests verify item and visible-row retention.

This change cancels approval-blocked tools when a run ends. Two edge cases remain. A failed tool-state read can block a run from reaching its terminal state. A cancelled tool that never emits a final event can keep the run's event subscription open. Both should be fixed, but each is narrow and recoverable.

Explanation
The title "fix(server): cancel approval-blocked tools when runs end" is a conventional commit title that names the primary change: run finalization now cancels run-owned command and dynamic-tool items that are pending or waiting on a pending approval. It matches the raw summary, the objectives, and the description's Change section. It does not cover the client reducer or the event-sink guard, which is acceptable for a title.
Full details: Description check
Explanation
The description covers the required template sections. Problem gives the symptom and links issue #22957. Change explains the finalization cancellation and the SQL/replay and client reducer updates. Scope states the limits, excluded file-change items, and the related issue #21935. Verification lists the targeted tests, results, and what was not checked, including live Claude behavior. The template's HTML comments are absent, which is acceptable. The description does not give exact reproduction steps, but the Problem section names the trigger (runtime-mode change failing a run) and the affected shell UI. The description is mostly complete.
Full details: Linked Issues check
Explanation
Issue #22957 is closed and is marked historical context only. No active directly linked targets remain, so no linked-issue coding requirements apply to this pull request. The PR objective in the supplied PR summary is also historical. The current code still implements the behavior described in the PR description: run finalization cancels pending command/dynamic-tool items and approval-blocked items with pending runtime requests (RunExecutionService), EventSink guards preserve accepted or non-pending approvals, and the client projection rejects late active updates for cancelled tools. Incremental change since the last reviewed head 6613295 is a merge from main and a client-runtime test commit (4dc9446). Those changes do not alter the cancellation logic in the files reviewed. Limit: the incremental diff could not be read in full because the diff exceeded the inspection buffer. The merge's server-side changes were not inspected in detail.
Full details: Out of Scope Changes check
Explanation
The changes match the PR's stated purpose: cancelling approval-blocked run-owned tool items on run finalization. They touch ProjectionStore, ProviderTurnStartService, RunExecutionService, EventSink, the client projection, and related tests. These files support the same cancellation path across server persistence, replay, and shared client projection. The PR does not repair historical rows, does not cancel approval-blocked file-change items, and does not change the Stop/delegated-cancellation path of #21935, as the PR description states. No demonstrated unrelated change was found. Limit: the latest incremental diff could not be read in full due to the inspection buffer limit.

Main now expires a detached session's pending approvals before the run
finalizes, so the cancel pass treats any unresolved approval child as proof
the tool never started. It reads only the run's tool and approval rows
instead of the whole recovery projection. Trim the integration test to the
cases that fail without the fix plus the two that must keep running.

A failed loadRunOwnedTools read blocks run finalization.
yield* input.loadRunOwnedTools() has no fallback. If the projection read or any row decode fails, writeFinalRunEvents fails before it writes the terminal run.updated, node.updated, and run-attempt.updated events.
On the provider-terminal path, the error becomes a RunExecutionIngestError. The ingestion failure handler then retries finalization with the same loader, so the retry hits the same failure.
The run can stay running until the read succeeds.
The sibling loaders loadRunInterruptReason and hasUnpairedRunInterruptRequest both use Effect.catchCause with a safe fallback.
Tool cancellation is best-effort cleanup. It must not gate the terminal write.
Catch the failure, log a warning, and continue with no cancellations.

Finalization builds approval cancellations from a read taken before its
write, so an approval accepted in between was overwritten as cancelled and
its tool marked never started. The write now rechecks each approval inside
the transaction and drops the cancellation, and the blocked tool's, when the
request is no longer pending.
Only server-closed approvals (pending, expired, or cancelled as
not_resumable) prove a tool never started. Claude also cancels a request a
PermissionRequest hook allowed, and that tool runs.

…blocked tool
The finalization guard kept the tool running whenever its approval was no
longer pending. A server-closed (not_resumable) approval proves the tool never
started, so only an accepted approval, or one Claude withdrew with a live
capability after a hook allowed the tool, now preserves it. The released
approval's own outcome is still kept.

🟠 Highorchestration-v2/EventSink.ts:387
A resolved decline or cancel response makes this guard suppress the parent tool's cancellation, leaving a never-executed command running indefinitely if the run closes before a provider tool-result arrives. Orchestrator.ts records these responses as status: "resolved" and stores the decision separately, so only suppress parent cancellation when that decision allows execution.

The automated pipeline stopped on this pull request and will not merge it:
the capture step could not show the problem on the base commit, so there is nothing to prove fixed.
On both commits, started a Claude thread in Supervised mode and requested two separate parallel Bash calls: vmstat 1 3 and top -b -n 1 | head -15. Left approval pending, switched to Auto, and sent a follow-up requesting replacement commands if necessary. Repeated with the follow-up drafted immediately after the initial send. Both sides declined the first command during the redirect, exposed the second approval, and remained in the original running run. Neither reached the reported failed-run and completed-successor state.

Clear committed tool cancellations from activeBackgroundTurnItems.
A pending command_execution or dynamic_tool item is added to activeBackgroundTurnItems when its non-settled event arrives. The finalizer cancels such items through cancelledToolEvents (line 924), but it never removes their IDs from that set. Those cancellation events do not pass through trackChildLifecycle, which runs only for provider events.
For a completed terminal event, shouldStopProviderEventIngestion returns false while that set is non-empty (lines 1510-1512). A cancelled tool that no later provider event settles can keep the provider event subscription open until another event or shutdown.
Remove each cancelled item's ID from activeBackgroundTurnItems after its guarded cancellation write commits. A removal before the write could end ingestion while the item is still pending in storage, if the write fails.
