fix(server): Claude turns whose CLI exits before its first frame fail instead of running forever - #33008
A Claude run stays Working forever, and Stop sits at "Stopping" forever, when the Claude CLI exits right after a new native query opens, before it writes any frame. The provider log shows query.open, prompt.offer, then nothing. Stop never finishes: the provider-turn.interrupt effect fails all five attempts with Claude provider thread … has no live query., so the run is never terminalized and the thread is stuck until the server restarts.
Reproduced on main (ade473018d) in the real app. A claude wrapper on PATH runs the real CLI, except that a resumed query (--resume) exits immediately without output. Turn 1 completes normally; switching the permission mode before turn 2 forces a new resumed query, and that run never leaves Working. Exit codes 0 and 1 behave the same.
Change
startTurn opens the query (which starts consuming its message stream), then reads the auto-compact window from settings, then attaches the turn. If the CLI's stream ends during that gap, the stream's exit handler drops the dead query but has no turn to finalize yet. The turn then attaches to the dead query, and nothing ever ends it.
attachTurn now claims the live query atomically: in one Ref.modify on the query context it checks that this query is still the live one and not stopping, and only then records the turn on it. activeTurn is set just before the claim. An exit that wins the race therefore makes the start fail with "Claude provider query ended before the turn could start.", which surfaces as a visible provider error and releases the thread. An exit that loses the race finalizes the attached turn as failed, as before. The continuation path already had a non-atomic version of this check; both paths now share the one in attachTurn.
Two existing test fixtures used an empty message stream to stand for a query that stays open. That now correctly reads as a CLI that died, so they use Stream.never.
Tests.fails a turn whose Claude query ends before its first frame in ClaudeAdapterV2.test.ts holds the settings read on a Deferred until the dead stream has ended, so the race is pinned without timing. It asserts the start fails with Claude provider query ended before the turn could start. and that the next start is accepted. Against main's adapter it fails with a turn whose Claude query ended before its first frame started running on the dead query. The whole file passes (348/348), and vp run check:changed passes on the final head.
Captures were made on 966a7d2; the final head 5588975 adds only a merge of main that does not touch the adapter or its tests.
Evidence
Captured 5/5 affected matrix rows for #33008: R1–R3 in the real app on both revisions; R1-C and R1-S as explicitly labelled adapter harnesses. All nine matrix rows are accounted for below.
Environment for every image and recording: Linux x86_64, headless Chrome 151.0.0.0 / Playwright 1.60, no device emulation, DPR 1, browser zoom and font scaling 100%, 1280×900 CSS-pixel client viewport, dark, UTC, reduced motion. PNGs add a 76-pixel evidence caption below the unchanged viewport. Each checkout ran its own real server/web build and freshly created database with T3CODE_DEV_SEED=0; identical synthetic project, thread, prompts and CLI. One viewport/theme suffices because no rendering code changed.
The same run-sequence.py drives both sides: establish a completed turn, start recording, arm a zero-frame resumed CLI exit, wait 6 seconds, capture R1, click Stop only if available, wait 8 seconds, capture R2, disarm and submit the same-thread follow-up, wait 6 seconds, capture R3. Every still waited for network idle and fonts, then passed two unmasked, pixel-identical full-viewport probes at least 500 ms apart. Date is frozen during each probe pair; server/driver UTC stays live. All six final images, all six diffs, and sampled frames throughout both videos were opened and inspected before upload. The browser clock is frozen during each still's probe pair, so on-screen timers pause in the recordings; the UTC log milestones establish how long each state persisted.
R1 — CLI exits before its first frame (1280×900, dark). Before: submit 09:19:39.674 → CLI exit 09:19:39.813 → still Working at 09:19:46.990. After: submit 09:16:54.913 → CLI exit 09:16:55.030 → exact Claude provider query ended before the turn could start. failure at 09:16:55.062 → settled Failed/composer at 09:17:02.271. No failed-run prompt is offered on After. Recording segments are approximately 00:05–00:13 Before and 00:04–00:12 After.
R2 — Stop consequence (1280×900, dark). Before: actual Stop click 09:19:47.313 → fifth has no live query interrupt failure 09:19:48.886 → Stopping still present at 09:19:57.581. After: the shared driver finds no Stop at 09:17:02.445 because R1 already failed; it retains that state through 09:17:11.584. No artificial fixed-side Stop interaction. Recording segments: approximately 00:13–00:23 Before and 00:12–00:21 After.
R3 — next message, same thread (1280×900, dark). Before: follow-up accepted at 09:19:57.805 but still queued at 09:20:06.227. After: follow-up accepted at 09:17:11.839 → RECOVERY COMPLETE at 09:17:11.973 → success result 09:17:11.978 → settled still 09:17:19.978. The server, database, thread, provider session and native session remain the same within each side; After reuses native session c813875f-3cd8-42e2-9dc6-21c7e7f64e12. Recording segments: approximately 00:23–00:32 Before and 00:21–00:30 After.
Diff0: ImageMagick compare -fuzz 0%, every changed pixel amplified to white against black. DiffT: the same comparison at 5% fuzz. Full PNGs, including captions, are compared. Changed pixel counts (0% / 5%): R1 101,336 / 65,521; R2 102,293 / 66,398; R3 56,893 / 54,891.
Matrix row
Final-head evidence and limits
R1-C, provider continuation
Harness only, 966a7d2: source and passing transcript. Agent/provider provenance, no user prompt, Deferred-gated stream exit before claim, exact common rejection. No claim about real-app wake routing.
R1-S, same query stopping before claim
Harness only, 966a7d2: source and passing transcript. Start pauses in settings; fork marks this live/current query stopping; close remains blocked; settings releases; start rejects with exact error without offering a prompt; close then releases and fork completes. This isolates stopping from stream-exit identity loss.
C1, healthy user claim
Both recordings begin with a completed synthetic turn; After R3 also completes a resumed turn.
C2, healthy continuation/replay
Two focused existing adapter cases pass: native wake starts before output; buffered workflow outcome survives interrupted replay. Control transcript. No new UI capture.
C3, exit after successful claim
Existing prompt-echo/stream-end case passes in the control transcript. No new UI capture.
C4, live Stop
Existing acknowledged and bounded-unacknowledged Stop cases pass in the control transcript. No new UI capture.
What else changed:
Working/Thinking, elapsed timers and the lower Working sidebar group/count become a Failed entry in the upper project list; R3 returns to the normal settled entry.
After R1/R2 adds the top error banner and error activity with a timestamp. Banner-driven scrolling hides the first user bubble and shifts the first reply and second prompt. R3 removes the banner while keeping the prior error in history.
The red Stop control becomes the normal blue Send control; R2's Stopping indicator disappears.
R3's dashed queued bubble and Send now/edit/cancel controls become a sent bubble plus RECOVERY COMPLETE; related activity markers and row positions change.
Message/elapsed clocks and evidence captions differ. A handful of zero-threshold pixels near the sidebar divider/header disappear at 5% fuzz. No unrelated visible change was found.
Unverified: no affected row lacks its required medium. R1-C/R1-S remain harness-only: real-app continuation routing and the exact live fork/start gap were not seeded. Replaced-query identity and preservation of a different active context were not forced separately. C2–C4 have refreshed tests, not new browser recordings. Windows, the Electron shell and native mobile were not run.
Raw winning pixel probes, capture metadata, UTC scenario/driver milestones, synthetic CLI logs, credential-redacted server logs, recording probes and diff metrics: proof-data.zip. Additional sanitized setup/failure logs: capture-diagnostics-redacted.zip. Auth/catalog WebSocket results are excluded. Source, stills, recordings and transcripts contain synthetic data only.
Not covered. Windows (the reporter's platform), the Electron shell and native mobile were not run; the adapter code is platform-independent and the race reproduces on Linux. This change does not add a deadline for a CLI that stays alive but never writes, a Stop fallback for a turn whose query is already gone, or repair of a run that was stranded before this change.
Verification log
Review round 1 on 966a7d2: reviewer A found no code defect and asked for refreshed evidence of the continuation path; reviewer B recommended merge. Evidence was re-captured on 966a7d2 with recordings, and the continuation and stopping-before-claim guards were re-run as labelled harnesses.
Review round 2 on 966a7d2, with the evidence above: both reviewers recommend merge; no confirmed defects. Both ran ClaudeAdapterV2.test.ts (348/348); B confirmed the regression test fails against main's adapter.
Proof audit: pass 1 derived rows R1–R3, R1-C, R1-S and controls C1–C4 and asked for recordings and final-head captures; pass 2 found the evidence sufficient after opening every still, diff and sampled recording frames and rebuilding R1 After independently (125 differing pixels: clock text and anti-aliasing only).
vp run check:changed passes on the final head (format, lint, knip, typecheck, tests in changed files).

…the first frame (#33001)
These tests reproduce #33001. When the Claude CLI exits before writing a
frame, the query stream ends before startTurn attaches the turn, so the
turn is marked running on a dead query: it never terminalizes, the next
turn is refused as still active, and Stop fails with "has no live query".

…l instead of running forever
When the Claude CLI exited right after spawn, its query stream could end
while startTurn was still between opening the query and attaching the
turn. The exit handler found no turn to finalize, then startTurn marked
the turn running on the dead query, so it never finished and Stop failed
with "has no live query".
attachTurn now claims the query in the same step that checks it is still
live, after publishing the active turn. Either the query exit sees the
turn and finalizes it, or the start fails with a provider error and the
turn is released. The continuation path already had this check without
the atomic claim and now shares it. Two test fixtures whose fake CLI
exited immediately now keep their stream open.

Macroscope's review found this PR approvable — Claude turns now reject startup when their query has already exited, rather than remaining running indefinitely. The change is confined to turn attachment and existing failure handling, with identity checks protecting replacement queries.

Walkthrough
The Claude adapter now checks query ownership and stop state when attaching a turn. A regression test covers a query that ends before its first frame and verifies that a later turn succeeds.

Layer / File(s)
Summary
Turn attachment and regression coverage apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts
startTurn sets the active-turn context before claiming the query. If the query is no longer current or is stopping, the adapter clears the context if it still refers to this turn and returns a protocol error. Continuations use the shared guarded attachment logic. Tests cover a query ending before its first frame and verify that a follow-up turn succeeds. The fork and session-identity test fixtures now use streams that remain open.
The early-exit case now fails visibly and permits a subsequent turn to start. No issue requiring a fix before merge was established.

Full details: Linked Issues check
Explanation
For #33001, attachTurn now atomically rejects a query that ended before turn attachment, and the regression test checks rejection and later thread reuse. This covers the reported exit race. The issue also requires Stop to terminalize after a short grace period when the query is gone or does not acknowledge the interrupt. The PR explicitly excludes that behavior. The issue requires bounded failure when a query produces no frame; the PR adds no first-frame deadline for a live silent CLI, and the available evidence does not establish that the existing MCP registration timeout meets this requirement.
Resolution
Implement and test Stop terminalization after a short grace period when the query is gone or does not acknowledge the interrupt. Establish with code and tests that a query which produces no frame within a bounded time fails visibly and releases the thread; add timeout handling if existing behavior does not meet this requirement.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Review note: the atomic claim is sound, but Ref.modify mutates querySession inside the modifier.
The check and the lastTurn write run in one Ref.modify. The exit handler uses Ref.modify on the same queryContext ref, so the two cannot interleave. Either the claim wins, or the exit wins and the start fails. This closes the stranded-Working race.
One style concern remains. The modifier function writes querySession.lastTurn as a side effect. Ref.modify modifiers should be pure. In the current Effect runtime the modifier runs once, so the behavior is correct. A later change to the ref implementation could break this. Move the write out of the modifier:
This version is safe because the claim and the write happen in the same synchronous fiber step. No yield point sits between them.

compare -fuzz 0%, every changed pixel amplified to white against black. DiffT: the same comparison at 5% fuzz. Full PNGs, including captions, are compared. Changed pixel counts (0% / 5%): R1 101,336 / 65,521; R2 102,293 / 66,398; R3 56,893 / 54,891.What else changed:
RECOVERY COMPLETE; related activity markers and row positions change.Unverified: no affected row lacks its required medium. R1-C/R1-S remain harness-only: real-app continuation routing and the exact live fork/start gap were not seeded. Replaced-query identity and preservation of a different active context were not forced separately. C2–C4 have refreshed tests, not new browser recordings. Windows, the Electron shell and native mobile were not run.
Scripts: claude, browser-driver.cjs, scenario.py, control.py, launch.py, capture.py, run-sequence.py, diff-driver.py, extract-logs.py, continuation-evidence.test.ts, stopping-evidence.test.ts, package-evidence.py.
Raw winning pixel probes, capture metadata, UTC scenario/driver milestones, synthetic CLI logs, credential-redacted server logs, recording probes and diff metrics: proof-data.zip. Additional sanitized setup/failure logs: capture-diagnostics-redacted.zip. Auth/catalog WebSocket results are excluded. Source, stills, recordings and transcripts contain synthetic data only.
Not covered. Windows (the reporter's platform), the Electron shell and native mobile were not run; the adapter code is platform-independent and the race reproduces on Linux. This change does not add a deadline for a CLI that stays alive but never writes, a Stop fallback for a turn whose query is already gone, or repair of a run that was stranded before this change.
Verification log
ClaudeAdapterV2.test.ts(348/348); B confirmed the regression test fails against main's adapter.vp run check:changedpasses on the final head (format, lint, knip, typecheck, tests in changed files).AI-assisted; verified with the tests and tools listed above.
