Problem

When Claude starts a root turn by itself after T3's run has ended (a Monitor event, a background task finishing, a message from another session), the adapter buffers it and asks for a continuation run to show it. That run can start well after the turn does. Any approval or AskUserQuestion Claude raised in between was denied with "Claude V2 adapter has no active turn for this tool request." On one machine a continuation run started 2 minutes after its wake began, and the question asked 6 seconds in was lost.

Change

canUseTool now waits when a continuation run has been offered for that Claude session's wake, and raises the request in the continuation run that drains that wake, after the buffered frames replay. The wait belongs to the session it started in. It still denies when no run is coming, the continuation is cancelled or replaced, a user turn attaches first, Claude withdraws the request, or the process closes. A change signal on turn attach and wake-latch settle drives it; nothing polls. Since #36339 a Monitor continuation can drain only its own wake; a request whose tool_use is still buffered after that drain belongs to a later wake, and is denied as before rather than answered in the wrong run.

One case could otherwise wait forever: the continuation message goes to the thread's active provider thread, so if the active session is another one the run starts there and the original session never attaches. #36103 keeps wakes on the active session, so this still happens to a wake from the user's own conversation after a fresh-session scheduled run. ProviderContinuationService now treats a continuation run that starts on another provider thread like one that never started, which withdraws the original wake. That request is denied as before, and the wake no longer blocks later wakes from that session.

Scope

Fixes #20339 (root-turn case). Background subagents after the parent turn are #35428. The two touch one line in canUseToolEffect; if #35428 lands first, the order is: active turn, its settled-subagent fallback, then this wait.

Verification

• New ClaudeAdapterV2.test.ts case: a wake opens, Claude asks for Bash approval before the continuation run starts. On main it fails at once with the exact deny; with the fix the approval appears in the continuation run and approving allows the call. Three more cases wait until the request is pending, then cancel the continuation, withdraw the request, or attach a user turn first, and get a deny.
• New Monitor split case: a later wake's tool request waiting behind a Monitor continuation stays out of that run, and its tool appears only in the later wake's own continuation.
• New ProviderContinuationService.test.ts case: a continuation run that starts on another provider thread, while still running, releases the wake.
• vp run check:changed passes; ClaudeAutomaticDelivery.integration.test.ts, the Claude replay fixtures, RestartContinuation.test.ts and ProviderSwitch.integration.test.ts pass, as do fix(server): a Claude Monitor line no longer wakes a delegated child's parent #36339's Monitor wake tests.
• With fix(server): background Claude subagents still ask for approval after their parent turn ends #35428 merged on top (one-line conflict resolved as above), all of ClaudeAdapterV2.test.ts passed, including both PRs' tests (checked on an earlier main).
• Found from provider event logs and native transcripts on 0.1.9: a cross-session message started a turn at 12:11:52Z, AskUserQuestion was denied at 12:11:58Z, and the continuation run for that wake was created at 12:13:57Z.
• Not checked in a running app: scenarios:prove uses the replay agent, which never reaches the Claude adapter, and I did not run live Claude turns for this.

Approvability

Verdict: Approved at 3111225

Macroscope's review found this PR approvable — Autonomous Claude tool requests now wait for their matching continuation and use the existing approval flow instead of being prematurely denied. Query and wake ownership checks preserve request attribution, while cancellation and stale-continuation handling limit the wait.

Walkthrough

The changes update provider continuation latch handling and Claude tool-permission checks. Claude can wait for a matching wake continuation when no turn is active, then validate and attribute the request to the attached turn. New tests cover continuation timing, denial cases, and run attribution.

The change lets Claude wait for its continuation run before asking for tool approval in turns it starts itself. Two gaps remain in how the approval is assigned to a run. A resumed user turn can pick up a pending wake approval, and a request that arrives during replay can bypass the ownership check, so an approval may appear under the wrong run. The affected flow is narrow, but both gaps should be fixed before merging.

Full details: Title check

Explanation

The title names the main change: Claude no longer denies approvals in turns it starts on its own. The changeset adds a wait in canUseTool for self-started root turns so the request is raised in the continuation run. The title follows the conventional commit format and is specific. It does not cover the cross-provider-thread release in ProviderContinuationService, which is a secondary change.

Full details: Description check

Explanation

The description follows the template sections: Problem, Change, Scope, and Verification. The Problem section gives the failure and a reproduction timeline. The Change section explains the wait, the denial conditions, and the cross-provider-thread release. The Scope section links #20339 and explains what is excluded. The Verification section lists focused tests, the results, and what was not checked in a running app. The description does not use the template's conventional-commit comment, but that comment is guidance and not a required section. The author also states the model used, which the template asks for.

Full details: Out of Scope Changes check

Explanation

The changes stay within the root-turn wake wait for #20339. ClaudeAdapterV2.ts adds wake-latch signaling and a wait in canUseTool for a matching continuation, with checks for live query and buffered tool calls. ClaudeAdapterV2.test.ts adds cases for approval before continuation start, cancel, withdrawal, user-turn attach, and Monitor wake split. ProviderContinuationService.ts and its test release a wake when its continuation run starts on another provider thread. The PR states this is needed so the new wait cannot block forever when the continuation runs on the active session's other thread. ProviderContinuationRequests.ts changes only a comment. Each change supports the new wait or its tests. The Monitor split behavior depends on #36339 behavior that the PR preserves. No change was found that is unrelated to the root-turn wait.

Full details: Linked Issues check

Explanation

Directly linked issue #20339 asks that permission requests from background subagents not be denied with "Claude V2 adapter has no active turn for this tool request." after the parent root turn ends. The suggested fix is to decide the request from runtime policy or raise it against the subagent task. The PR changes only the root-turn case: canUseTool waits for a continuation run tied to a self-started root turn's wake. The PR description states that background subagents after the parent turn are deferred to #35428. The reviewed code therefore still denies background subagent requests after the parent turn ends, which is the primary symptom reported in #20339. The root-level denials after task_notification are covered by the wait, but the issue's main scenario is not. Tests cover the root-turn wake, Monitor split, and cross-thread release cases only. No test covers a background subagent request after the parent result. Requirements are coding requirements, so this assessment applies. Based on the PR summary and description, the subagent requirement is unmet.

Resolution

Either extend the fix to background subagent permission requests after the parent turn ends, following the suggested fix in #20339 (runtime policy or raise against the subagent task), with a test for that case. Or document with the issue owner that #20339 remains open for the subagent case and that this PR fixes only the root-turn part, so the linked-issue relationship and closing keywords reflect partial scope.

- Line 13012: Record consumed wake-token ownership only when
isClaudeProviderContinuationTurn(turnInput) is true, rather than for every turn
entering the replay branch. Extend the user-turn denial check to reject resumed
user turns as well, so replay cannot create an approval under a user run.
- Around line 11825-11827: Update the canUseTool callback’s activeTurn path so
it does not return the attached turn until wake ownership and buffered-tool
checks pass; alternatively, defer returning it until replay completes. Keep the
existing awaitWakeContinuationTurn checks for the continuation path, and ensure
callbacks cannot use a turn that does not own the wake.
