fix(server): show idle paragraphs before the assistant turn ends#28221

R15 and R16 runtime verification for head 27c2e13d491a3c0ad19e18f8f41fc2067771b88d, base 15fe2832727893cbdd2214383f9f971474849695. Both probes ran the actual unmodified source server on physical corex with Node v26.12.1, isolated real SQLite databases, synthetic git workspaces and a free gated ACP replay. No paid or real provider session was used.

R15, real disk full: passed. An unprivileged private user/mount namespace mounted only the disposable test storage as a 16 MiB tmpfs. After the paragraph prefix persisted and before idle delivery, the verifier checkpointed and truncated the WAL, then filled that tmpfs until allocation returned ENOSPC and zero blocks remained. An independent filesystem write failed, and the real server logged two idle-write failures ending in SQLite's database or disk is full. Removing the test filler restored space; an independent write succeeded. Events 29 and 30 and both projections then contained the full text with streaming: true while the same run remained running. The provider had emitted no new assistant text and was gated from finishing until those assertions passed. It then completed normally.

Disk-full milestones, UTC: zero free blocks at 19:10:26.553; SQLite failure observed at 19:10:27.343; space restored at 19:10:27.346; both streaming representations persisted at 19:10:29.404; run completed at 19:10:29.639. The verifier exited 0. The host filesystem was never filled.

R16, SIGKILL with an idle paragraph pending: observed as expected. At 19:11:37.994 UTC, the verifier captured the stored prefix and running run, then sent SIGKILL to its own server PID. After process exit and before restart, the full tail was still absent. A second source server used the same home and database. Startup recovery terminalized one run and stopped one session. At 19:11:43.766, both the real API and database showed the original run cancelled, the stored message still exactly First paragraph.\n\n with streaming: false, and the assistant turn item cancelled with its existing streaming: true flag. The verifier exited 0.

The unpersisted tail was lost on SIGKILL. continueThreadsAfterServerUpdate: false was explicit for this crash probe so provider replay could not stand in for recovery of the original held snapshot. This proves reconciliation at that crash cutpoint, not crash durability or default automatic continuation. This PR adds no durable buffer.

Commands, with temporary paths represented by <isolated-task>:

bash

1	unshare --user --map-root-user --mount sh -c 'mount -t tmpfs -o size=16m tmpfs <isolated-task>/disk-full/storage && exec /home/shivam/.local/share/vite-plus/js_runtime/node/26.12.1/bin/node <isolated-task>/disk-full/disk-full.ts'
2	/home/shivam/.local/share/vite-plus/js_runtime/node/26.12.1/bin/node <isolated-task>/crash/crash-pending.ts

A fresh independent GPT-6.1-Sol review read the raw logs, database snapshots and complete verifiers and resolved R15/R16 with no new findings or required source changes. Both servers and verifier processes are stopped. No source changes or new build were needed.

Earlier R13/R14 evidence also passed: a targeted SQLite trigger failure permitted an unrelated provider event to commit before restoration, and a separate BEGIN IMMEDIATE experiment blocked all database writers until ROLLBACK, after which both held representations retried while the run remained open. The first R14 observer attempt hit its own WebSocket heartbeat timeout and was excluded; the successful attempt lengthened only that observer timeout.

Real Antigravity behavior, native desktop/iOS rendering, power loss and default automatic continuation after a crash are outside these probes. Android Replay recordings remain embedded in the PR body.

Final-head tests and Android verification

Final verification for head 27c2e13d491a3c0ad19e18f8f41fc2067771b88d, base 15fe2832727893cbdd2214383f9f971474849695.

Macroscope R11 is fixed in 380a8e7967c2ed6dace51e0bfdca71a91f1d0a35. A newer snapshot now wakes an idle timer sleeping on a later retry deadline. Its regression fails an assertion against the preceding timer implementation and passes with the fix. Fresh independent delta review accepted it, with no open in-scope findings. CodeRabbit R12 is fixed in ae9a341c083e0b275f70379dfcb54b69c5f59e91: the original paragraph regression explicitly awaits the full idle delivery before offering later snapshots. The final commit captures narrowed test text before a callback to satisfy TypeScript. Four focused idle/retry cases and the server typecheck passed locally.

All production files are byte-identical to the reviewed and Android-recorded 380a8e7967c2ed6dace51e0bfdca71a91f1d0a35; the two later commits change tests only. The replacement Android video in the PR body comes from that server commit on physical corex's POCO F4, Android 14, T3 Code Dev native fingerprint 541b3da3e5f7b2ad504aaa6303bdcea8d7194d22, isolated state and the free Replay(dev) provider. It shows Send, both paragraphs, the synthetic background command still Running, and Stop available. The main-server video remains valid. The replay fixture was restored and the phone connection, phone lease, dev server and Metro were cleaned up.

Boat job j_5jqg64rhfhvtniyqh3pv, stage typecheck, large worker bx_gtez4ehm, attempt 1, exit 0, pinned to this final head. Command: vp i --frozen-lockfile then vp run check:changed "$FLEET_SOURCE_BASE". Format, lint, knip, GraphQL generation, affected typechecks and all 68 tests passed.

An earlier timer-fix job passed all 68 tests but failed a test-only TypeScript narrowing error. It is not counted as a pass. The queued job for the superseded test commit was cancelled; only the final passing job above covers this final head.

Unverified: a real Antigravity turn, desktop and iOS rendering, and live database failure recovery. Storage-error and timer-race behavior is proved through controlled service tests. The separate wake fix remains https://github.com/pingdotgg/t3code/pull/28204. No merge, auto-merge or approval was performed.

🟡 Medium orchestration-v2/RunExecutionService.ts:1402

After an idle-write failure, a new partial snapshot remains hidden until the old retry deadline or another provider update. scheduleIdleFlush returns when idleFlushTimer is already set, so it never wakes the timer when the new snapshot introduces an earlier nextIdleFlushAt(); reschedule or wake the timer when that deadline moves earlier.

No longer relevant as of 27c2e13d491a3c0ad19e18f8f41fc2067771b88d

Fixed in 380a8e7967c2ed6dace51e0bfdca71a91f1d0a35. The timer tracks its armed deadline and is replaced under the ingestion lock when a new snapshot is due earlier. The regression fails on the prior implementation after two idle-write failures and passes with the fix. A fresh independent review accepted the correction.

Approvability

Verdict: Approved at 49dddb8

Macroscope's review found this PR approvable — Held assistant text now becomes visible after a short idle pause, even before the turn ends. Flushes use ordered ingestion with routing and finalization safeguards, while turn-only streaming remains unchanged.

Walkthrough

The assistant streaming filter now holds paragraph updates for idle delivery and tracks delivered text and deadlines. RunExecutionService processes flushes alongside provider events and tracks pending work reported by stored root snapshots. EventSink and ProviderCommitBatch accept generic typed events, including consumer control items.

Changes: Assistant streaming and idle flushes

Layer / File(s)	Summary
Track and deliver held assistant text `apps/server/src/orchestration-v2/assistantStreaming.ts`, `apps/server/src/orchestration-v2/assistantStreaming.test.ts`	The filter tracks delivered text and held snapshots by message. It returns due snapshots after idle deadlines. Tests cover delivery timing, rewrites, truncation, and turn-mode behavior.
Allow control events in batched ingestion `apps/server/src/orchestration-v2/EventSink.ts`, `apps/server/src/orchestration-v2/ProviderCommitBatch.ts`	The event sink and commit batch accept generic events with a string `type`. Their contracts describe how non-provider snapshots are handled.
Integrate idle flushes with provider ingestion `apps/server/src/orchestration-v2/RunExecutionService.ts`, `apps/server/src/orchestration-v2/RunExecutionService.test.ts`	RunExecutionService merges idle-flush ticks with provider events, routes and ingests due snapshots, and closes flushing when terminal conditions apply. It tracks pending work from stored root snapshots. Tests cover batching, interruption, continuing children, and handoffs.

Await the idle delivery before the test offers later events.

paragraphDelivered is set by the first turn_item.updated ingestion. That ingestion is the immediate prefix write ("First.\n\n"), not the idle flush. After TestClock.adjust("1 second"), the test does not wait for the idle write of "First.\n\nWaiting on the build".

The test then offers the next snapshot ("…build to") at once. If the timer fiber has not yet taken ingestLock, filter replaces the held event with the newer snapshot. The idle flush then delivers "…build to", or nothing, and the exact assert.deepEqual at Lines 3904-3911 fails. The result depends on fiber scheduling, so the test can be flaky. The other new tests avoid this by awaiting a Deferred set during the flush.

Set a second Deferred when the streaming turn_item.updated with text "First.\n\nWaiting on the build" is ingested. Await it after the TestClock.adjust. This follows the testing rule to await "the specific persisted event or Deferred that marks the milestone".

✅ Addressed in commits 380a8e7 to 27c2e13

Fixed in ae9a341c083e0b275f70379dfcb54b69c5f59e91. The regression now awaits a separate Deferred completed only by the full streaming turn item before offering the later snapshots. The focused idle-delivery and retry cases pass.

Thanks @shivamhwp for splitting and fixing both the sibling wake preservation (#28204) and the 800ms idle paragraph flush here!

One quick heads-up from our deeper forensic trace on #28175 (detailed in https://github.com/pingdotgg/t3code/issues/28175#issuecomment-6547340402):

While flushing the held paragraph after 800ms fixes the truncated final paragraph text while the turn is open, we also traced why the Antigravity ACP turn itself stayed open (streaming: true / running) indefinitely on every subsequent turn after a single interrupted background command:

In agy_acp_server.par, server.py:5488-5496 is designed to let a turn complete cleanly while background _EXEC_TOOLS (run_command) remain open by moving them into session_info.persisted_open_tool_calls.
However, when localharness_external finishes the model's final PLANNER_RESPONSE step while a background task is active—or when a previous turn was interrupted (session/cancel) while a background run_command was running, leaving a zombie status = 2 (RUNNING) step in conversations/<session_id>.db across session/load—localharness_external emits TrajectoryStateUpdate(state=STATE_WAITING_FOR_TASKS) (4) instead of STATE_FULLY_IDLE (1).
Because google3/third_party/py/google/antigravity/connections/local/event_processor.py:958-982 only puts None into step_queue on STATE_FULLY_IDLE or STATE_CANCELLED (and ignores STATE_WAITING_FOR_TASKS), receive_steps() and session/prompt block forever—keeping the turn stuck in running state on every future turn in that thread.

We patched this locally in agy_acp_server.par by treating STATE_WAITING_FOR_TASKS with no active model/sync-tool steps (plus emitting _acp_step_done when PLANNER_RESPONSE with no tool_calls finishes) as end-of-turn, which immediately resolved the permanent turn hang.

main hides the held paragraph while the real codex message remains open

R13 runtime evidence for head 27c2e13d491a3c0ad19e18f8f41fc2067771b88d, base 15fe2832727893cbdd2214383f9f971474849695.

On physical corex, Node v26.12.1 ran the source server from this clean head against an isolated, real file-backed SQLite statev2.sqlite. A free controlled ACP replay emitted two paragraphs and kept its prompt open. No production source, adapter, ingestor or persistence code was replaced or mocked.

An external SQLite BEFORE INSERT trigger rejected only the full streaming message and turn-item snapshots with RAISE(ABORT, 'probe_idle_storage_failure_28175'). The actual server logged ProviderEventPublishError through EventSinkWriteError, EventStoreAppendEventsError and PersistenceSqlError, ending in SQLite error 1811 from that trigger. Two idle write attempts failed before restoration.

The captured sequence, in UTC:

18:35:49.726: the first SQLite failure was observed. The full held text was absent from the event log and both projections; the same run was still running.
18:35:49.752: a later provider metadata update committed as event sequence 28 while the trigger remained installed and the full text remained absent. This proves normal provider ingestion continued through the fault.
18:35:49.753: the trigger was dropped to restore writes.
18:35:51.797: the original full text was present in both message and turn-item projections, with streaming: true, through events 29 and 30. The same run was still running. The provider had sent no new text and was gated from completing its prompt until these database assertions passed.
18:35:52.117: after the proof released the provider, another provider update persisted and the run completed normally. The verifier exited 0 and stopped its server.

The transcript includes the actual SQLite error chain, ordered event rows, projection snapshots and assertions. The verifier source is included for inspection; local paths are replaced with placeholders. A fresh independent GPT-6.1-Sol evidence review accepted R13 with no new findings. It checked the raw logs, database snapshots, provider gates and public transcript, including that final text events occur later at sequences 33 and 34.

353	Limitations: trigger-induced SQLITE_CONSTRAINT_TRIGGER failures cover the real event-store transaction/error path and timed retry. They do not prove disk-full, corrupt media, read-only filesystem, a whole-database outage, process crashes, real Antigravity, desktop or iOS. Two idle writes failed while the trigger was installed; both message and turn-item full text later persisted before the prompt was released.

This resolves the missing live-database retry evidence. It proves a targeted SQLite transaction failure and restoration, not disk exhaustion, corruption, a read-only filesystem, a whole-database outage or process-crash recovery. Real Antigravity and desktop/iOS rendering remain unverified. Existing tests and Android recordings remain at https://github.com/pingdotgg/t3code/pull/28221#issuecomment-6547165457.

Verified in a real dev environment

verified unchanged head 49dddb89b94b979a81e4a9fee90995590cbc35a1 against github/main at 331889a13560e6d8885629e2a6e89b2203ebf2cf on linux, 2026-11-10. no source changes or pushes were needed.

ran vp i in separate main and pr checkouts, then the real vp run dev in the background, one server at a time. created a project pointing at a real local git repository and threads through the web app. exercised the actual web client, codex adapter, orchestration, sqlite persistence and reload using repository playwright, /usr/bin/google-chrome, and real codex gpt-6.1-sol through the local proxy.

a temporary passthrough executable paused the real codex process and subsequent stdout forwarding for 15 seconds after real text deltas. it generated no provider output and preserved output bytes. the matching main/pr cases paused after STREAM HELD TAIL. this proves a controlled provider pause, not a natural provider hang.

main hid the held tail throughout the pause. it appeared when the assistant message completed.
the pr delivered the tail while that assistant turn item was still streaming: true, status: running. reloading the actual client during the pause retained the tail. completion preserved the exact text without duplication.
settings > threads > advanced > response streaming > wait for the full response kept partial text hidden during another pause, then displayed the complete response. restored paragraph mode afterward.
stop after idle delivery left the run interrupted, with streaming false after the provider resumed and on a later read. the pause delayed cancellation and remaining text arrived after the click; this does not prove immediate cancellation or frozen text.

runtime transcript, utc, from provider forwarding logs and read-only sqlite events:

blacksmith ran vp test run apps/server/src/orchestration-v2/assistantStreaming.test.ts apps/server/src/orchestration-v2/RunExecutionService.test.ts: 78 tests passed. all 33 head checks reported success. no check:changed rerun was needed because verification changed no source.

the clips are normal-speed chronological captures with startup splash removed. the pr clip cuts past reload loading frames. captures were inspected. uploaded mp4 playback and seeking were checked in t3's browser player; the same clips are embedded below as gifs for github rendering.

pr delivers the held paragraph while the real codex message remains open

main keeps the held tail hidden until message completion

pr idle delivery, retained text after reload, and intact completion

Not verified

native electron, ios and android; natural antigravity hangs and other providers; remote relay or tunnel; child-run handoffs; storage failure recovery and abrupt provider death. runtime persistence proof here covers the assistant turn items used by the client, not both message representations. the deterministic early-clock-wake case is covered by the focused tests, not a real clock anomaly.

Rebased the streaming fix on current main and resolved the ingestion conflict while preserving main's token telemetry. Current head 5fe1333279d653dea2a7fac2e0894cd475f2ba0a, base b92c8f473990cbc73b5320461bd06b9e26d4031b. git range-diff shows only main's telemetry changes moved into ingestDelivered; the remaining six commits replayed unchanged. The idle splitter, retry, ownership, and cancellation behavior is unchanged.

Fresh independent GPT-6.1-Sol review found no new findings. It confirmed telemetry and interrupted-reason behavior from main is preserved. R1–R16 remain resolved; this update adds no R17 finding.

Boat job j_h6baeeqexo7zt2kphsqq, stage typecheck, large worker bx_3bbybb8y, attempt 1, exit 0, pinned to this head and base. Commands: vp i --frozen-lockfile, vp run check:changed "$FLEET_SOURCE_BASE", then vp test run apps/server/src/telemetry/ProviderUsageAnalytics.test.ts apps/server/src/orchestration-v2/RunExecutionService.test.ts apps/server/src/orchestration-v2/assistantStreaming.test.ts. Changed checks pass with 70 tests; the additional focused run passes all 74 tests. These counts overlap.

The real runtime probes below ran again on this exact clean head on physical corex, Node v26.12.1, against isolated real SQLite databases and a controlled free ACP replay. No production database or provider account was used.

Disk-full recovery passed. A private 16 MiB tmpfs was filled while full text remained held. An independent filesystem write also failed with ENOSPC. The real server logged two SQLite disk-full idle-write failures. After restoring space, provider ingestion continued and both full text representations persisted with streaming true while the same run and provider prompt remained open. Prompt completion happened only after those assertions.

SIGKILL/restart passed with the documented durability limit. The server was killed after the prefix persisted but before the 800 ms idle deadline. The full tail was absent both before and after process exit. Restarting against the same isolated home cancelled the original run, retained the prefix, and cleared the message's streaming flag. The cancelled assistant turn item's existing recovery payload still carries streaming true. The unpersisted tail is lost. Automatic continuation was disabled to isolate startup reconciliation.

The complete verifier sources and earlier baseline evidence are in https://github.com/pingdotgg/t3code/pull/28221#issuecomment-6547165457. These reruns used those same R15/R16 scripts with only the asserted head/base and isolated paths replaced. Runtime commands:

bash

1	unshare --user --map-root-user --mount sh -c 'mount -t tmpfs -o size=16m tmpfs /tmp/t3code-28175/disk-full/storage && exec /home/shivam/.local/share/vite-plus/js_runtime/node/26.12.1/bin/node /tmp/t3code-28175/disk-full/disk-full.ts'
2	/home/shivam/.local/share/vite-plus/js_runtime/node/26.12.1/bin/node /tmp/t3code-28175/crash/crash-pending.ts

Unverified on this head: new client recordings, natural Antigravity bridge hangs, native desktop/iOS rendering, automatic provider continuation after restart, and crash durability of buffered text. Earlier Android and independent real-Codex captures remain historical evidence linked in this PR; the rebase changes telemetry integration only.

Limit the idle-flush failure warnings during persistent storage failures.

A failed idle write logs a warning with the full cause on every retry. The backoff stops at 30 seconds. During a full-disk failure, each stuck run therefore logs about 120 warnings per hour. This is the storage-failure case that the PR's disk-full probe tests.

The run-failure retry in this file already handles this risk. At Lines 1734-1735 it says "Persistent storage failures must not flood the same disk" and allows one warning per 10 minutes. The idle-flush path does not have the same limit.

Track the time of the next allowed warning, as the finalization retry does. Keep the failures count in the warning so that operators can see how many retries there were.

Proposed fix

diff

1	let idleFlushFailures = 0;
2	+ // Persistent storage failures must not flood the same disk.
3	+ let nextIdleFlushWarningAt = Number.NEGATIVE_INFINITY;
4	...
5	idleFlushFailures += 1;

7	- runId: input.run.id,
8	- failures: idleFlushFailures,
9	- cause: written.cause,
10	- });
11	- const retryAt =
12	- DateTime.toEpochMillis(yield* DateTime.now) +
13	- Math.min(1_000 * 2 ** (idleFlushFailures - 1), 30_000);
14	+ const failedAt = DateTime.toEpochMillis(yield* DateTime.now);
15	+ if (failedAt >= nextIdleFlushWarningAt) {
16	+ yield* Effect.logWarning("orchestration V2 idle assistant text flush failed", {
17	+ runId: input.run.id,
18	+ failures: idleFlushFailures,
19	+ cause: written.cause,
20	+ });
21	+ nextIdleFlushWarningAt = failedAt + 10 * 60_000;
22	+ }
23	+ const retryAt =
24	+ failedAt + Math.min(1_000 * 2 ** (idleFlushFailures - 1), 30_000);

Reset nextIdleFlushWarningAt where idleFlushFailures = 0 is reset, so that the first warning of a new failure is logged at once.

✅ Addressed in commit fb8d99b

Sshivam8d ago

R17 is fixed in fb8d99b7de1a06388229c819595c201268eeff5a. Idle-write warnings now follow the existing ten-minute storage-recovery limit. Retry counts and backoff remain unchanged, and a successful idle write resets the warning deadline. Changed checks and real isolated disk-full recovery and crash/restart probes passed on this head. Current-head commands, logs, and assertions are in the PR body.

CcoderabbitaiBot8d ago

@shivamhwp The supplied code addresses R17. Idle-write warnings now use the ten-minute limit. Retry counts and backoff remain unchanged. A successful idle write resets the warning deadline so a new failure can warn immediately.

Await the newer idle-flush write directly.

The marker can acquire ingestLock before the due idle-flush fiber. Complete a Deferred when "New partial response" is ingested, then await it after the 800 ms adjustment.

✅ Addressed in commit 0d707b8

Sshivam7d ago

R19 fixed in 0d707b8e50a3294992d6a108a594d98ee9e3efdd. The test now signals a Deferred when the newer text is recorded and awaits it directly after the clock adjustment. The final marker event was removed. The focused test and all 71 tests in check:changed pass on this commit. Production code is unchanged.

CcoderabbitaiBot7d ago

@shivamhwp The supplied code confirms that newerWrite signals after the newer text is recorded. The test awaits that signal after the 800 ms clock adjustment, and the final marker event is removed. This addresses R19.

Thanks for reporting the focused test and all 71 tests passing.

Fresh exact-head client and runtime evidence

Candidate: db22aa9b525870b89027c8e1cf7af28de04fce21. Baseline: cefb544af3c98224874419198c0359b652ca3c94. These results describe those exact builds. Natural Antigravity hangs remain unverified.

Real macOS desktop client

Physical shiv Mac mini, arm64, macOS 27.0.1 build 26A434. Both clean detached checkouts were freshly built. The real compiled T3 desktop main/preload launched its freshly bundled server and web client: T3 0.1.6, Electron 44.10.0, embedded Node 24.22.1. Build host Node was 26.12.0. This was an unpackaged source desktop build.

For each checkout, the recorded commands were:

1	vp i --frozen-lockfile
2	# From apps/desktop:
3	node scripts/build-browser-secret.mjs && node scripts/build-preview-annotation-css.mjs && vp pack
4	# From the checkout root:
5	vp run --filter t3 build

Install/build commands exited 0; server/web build output reported vp run: 2/2 successful. Build provenance records clean status and SHA-256 hashes for server, desktop main/preload, and client assets. Candidate server bundle hash: 83b3e2369af9467d9614e2945fd9e2c48e6c19ff7d02317759494ec0c2de5cc0; baseline server bundle hash: ec7a34581f7ef343848099e1f33e3e18c22994b5722df05117bbb49aefb12f11.

An external loader isolated Electron's home/appData and explicit T3 home/port, then required the unchanged compiled desktop main. It did not alter the product's streaming logic, provider adapter, persistence, or UI. A free controlled ACP provider supplied gated text and a running command. Projects and threads were created through the real APIs; SQLite snapshots were read-only. No projection rows were injected. Background GUI control and window-only MP4 recording captured test data only.

Case	While the command and prompt remain open	After completion or Stop
Baseline paragraph mode	Only `First paragraph.` appears; the command and run remain running and Stop is available.	Both paragraphs appear.
Candidate paragraph mode	Prefix appears first; after releasing the tail gate the full paragraph appears while the same command and run remain running.	Full text retained; message and item no longer streaming.
Candidate full-turn mode	No assistant text appears despite both chunks being released.	Full text appears and is retained.
Candidate cooperative Stop	GUI Stop interrupts the controlled ACP provider.	One interrupted run; message/item nonstreaming; releasing the completion gate causes no extra run or reopening.

The tail is This held paragraph appears while the command and turn stay open. Both desktop runs use the same chat view and input. assert-evidence.py and the saved state/UI snapshots support PASS: 32 persisted-state and UI assertions. Independent read-only review inspected baseline/candidate recording frames, held/final screenshots, full-turn and Stop frames, the assertion source, and SQLite snapshots; no blocking evidence finding was found.

Recordings and useful offsets:

before/desktop.mp4 (21.72 s): tail gate at 0.306 s; prefix-only until completion gate at 8.271 s, then full text.
after-recorded/desktop.mp4 (94.02 s): prefix gate 6.240 s; tail gate 17.431 s; full text with Running and Stop at 20–45 s; completion gate 45.946 s, then retained full text.
full-turn/desktop.mp4 (85.048 s): both chunks released at 0.067/0.108 s; no assistant text before completion at 84.822 s. The separate completed window screenshot and state snapshot establish retained completion.
stop-cooperative/desktop.mp4 (61.535 s): tail gate at 38.646 s followed by GUI Stop; interrupted state persists after completion gate at 50.609 s.

Physical-corex disk-full retry

Node 26.12.1 ran the exact clean candidate source server against an isolated real file-backed SQLite database on a private 16 MiB tmpfs. The standalone fixture creates a real project/thread through APIs and uses a free controlled ACP provider. Its control program checkpoints the WAL, fills only that bounded private filesystem, and waits for the actual idle-write warning before restoring space.

Command, on physical corex:

1	unshare --user --map-root-user --mount sh -c \
2	'mount -t tmpfs -o size=16m tmpfs /tmp/t3code-28221/disk-full/storage &&
3	exec /home/shivam/.local/share/vite-plus/js_runtime/node/26.12.1/bin/node /tmp/t3code-28221/disk-full.ts' \

13	12:54:12.710 provider-completed-after-proof runStatus=completed

The real server log includes orchestration V2 idle assistant text flush failed caused by Error: database or disk is full. Assertions require the warning, actual full-disk error, zero free blocks, an independent ENOSPC write failure, absence of the held full text during failure, successful filesystem writes after restoration, and full text persisted in both streaming representations while the original run remains running.

The database transcript also records provider metadata PROVIDER_INGESTION_AFTER_DISK_SPACE_RESTORED at sequence 28, before retry sequences 29/30. This proves provider ingestion continued after storage restoration while the idle retry was pending. It does not claim database writes succeed while the disk is full. The provider emits no new assistant text and does not complete its prompt until the retry assertions pass. Result: status=passed, realSQLiteFailure=true, realDiskFull=true, heldTextRetriedWhilePromptOpen=true, failureCount=1.

Physical-corex crash with a pending paragraph

The second standalone fixture uses the same exact source server and another isolated real SQLite database. It waits for the persisted prefix with an unfinished tail still withheld, SIGKILLs the captured server PID, then restarts the server against the same isolated home. Automatic continuation is explicitly disabled.

9	turnItemStatus=cancelled turnItemStreaming=true fullHeldTextAbsent=true

Result: status=passed, restartSameHome=true, persistedPrefixRetained=true, unpersistedTailRecovered=false. The tail is memory-buffered and is lost at this crash cutpoint. The assistant turn item is cancelled but retains the pre-existing streaming:true payload; the message is nonstreaming. This is an observed recovery state, not a claim that pending text is durable or resumed.

Limits

Natural Antigravity hangs remain unverified. The desktop repro uses a controlled ACP prompt held open by gates. It proves idle delivery, not resolution of a naturally hung provider.

Exact 800 ms scheduling belongs to the focused clock-based tests; the recordings establish delivery before prompt completion. Cooperative Stop is covered; forced cancellation of an unresponsive provider is not. iOS was attempted but the cached-client upload failed because the Simlock worker holding the device was disconnected; no iOS rendering claim is made. These artifacts alone do not prove Android, separate browser/remote-client rendering, relay/T3 Connect, other providers, signed release packaging, or crash recovery with automatic continuation enabled.

Desktop cleanup records captured processes stopped, ports free, disposable profiles/worktrees/app removed, and no active iOS session. The parent owns publication, other verification, and the final ready check. No readiness or current-GitHub-head claim is made by this evidence review.

Physical corex runtime used Node v26.12.1, clean exact-head source, separate real file-backed SQLite databases and a free gated ACP fixture. Filling a private 16 MiB tmpfs caused an actual idle SQLite write failure. Independent filesystem writes failed with ENOSPC. After restoration, provider metadata persisted at sequence 28 before the held full text at sequences 29/30. Both text representations remained streaming, the original run stayed running and the prompt remained open. No new text or prompt completion triggered this delivery.

SIGKILL/restart of another isolated server retained only the persisted prefix and cancelled the original run once. Main now clears the cancelled turn item streaming flag, and this probe asserts that. The held tail was lost, as expected for an in-memory buffer. Automatic continuation was disabled.

Current-head desktop evidence is still being recorded by the existing shiv run r_hrgnoyrcibmmw000. Earlier recordings remain historical. Natural Antigravity hangs, current-head native mobile, relay/T3 Connect, signed installers and continuation-enabled crash recovery remain unverified.

https://github.com/user-attachments/assets/c737ee9f-ce22-498a-91fd-6c81ad099684

Fresh current-head macOS client evidence. Head fc00e3681d6f6bbe05061665ea063cf99cfcb945, baseline e68e19d605485db6ef31b2033f67a9d07634fc2b. These recordings replace the older db22 captures as proof for the current head. I personally inspected the recording frames showing the before/after trigger, open turn, both reload results, full-turn control and stable interruption.

Before: baseline hides the released tail until completion.

After: the tail is released at 5.744 s, visible at 8 s while Running and Stop remain available, retained across open-turn reload by 16.7 s, completion at 29.153 s and completed reload by 42 s.

https://github.com/user-attachments/assets/af61b4f1-ede1-4446-bd0c-2143d10de6e3

Full-turn control: both chunks remain buffered until completion at 11.449 s.

https://github.com/user-attachments/assets/3265aee9-79df-4a1f-9b81-f6108f2a8ede

Pending-text UI Stop: tail is released at 22.820 s, cooperative provider cancellation follows at 23.251 s. Releasing completion at 38.573 s does not reopen the run or change retained text.

PR28221 refreshed macOS evidence

Passed for the supplied candidate fc00e3681d6f6bbe05061665ea063cf99cfcb945 against baseline e68e19d605485db6ef31b2033f67a9d07634fc2b. The candidate came from the parent's unpushed bundle. This is evidence for those exact commits, not a live-PR ready-to-merge decision. The parent owns https://github.com/pingdotgg/t3code/pull/28221.

Build and isolation

Physical shiv, arm64 Mac mini, macOS 27.0.1 build 26A434. Fresh source builds of desktop/server/web 0.1.6. Electron 44.10.1, embedded Node 24.22.1, Chromium 152.0.7977.169. Build/fixture host Node v26.12.0.

The prerequisite was fetched from GitHub main, then the supplied bundle was fetched from physical corex. bundle-verify.log reports ../candidate.bundle is okay, requiring baseline e68e19d605485db6ef31b2033f67a9d07634fc2b and advertising candidate fc00e3681d6f6bbe05061665ea063cf99cfcb945. Detached worktrees had clean source before and after verification. No product source was edited.

build-provenance.json records the exact commits, clean status, package versions and SHA-256 hashes of all 2,208 desktop/server/client files per build. provenance-final-output.txt reports:

text

1	PASS: source and all compiled desktop/server/client hashes unchanged

Desktop main and preload, and web index, match between commits. Server entry hashes differ:

A disposable copy of this runtime launched the real compiled desktop main/preload, which launched the corresponding freshly built server and web client. This is an unpackaged macOS Electron app, not an installed old binary or browser stand-in. All launches used --use-mock-keychain; successful launch responses report self_activation_suppressed: true. GUI input used background cua-driver AX actions. wrec recorded only the T3 window, with no cursor or audio.

The external desktop-loader.cjs overrides os.homedir() and Electron home/appData paths to an isolated Electron home. It sets explicit per-case T3CODE_HOME and T3CODE_PORT, commit metadata, telemetry off and auto-update off; removes ambient dev-server/desktop-WebSocket overrides; records the PID/runtime and redirects stdout/stderr to the case log. It then requires the unchanged compiled desktop main. The actual HOME environment variable remained /Users/shivam-mini. No streaming, cancellation, projection, persistence, provider adapter, server, preload or client code was patched.

The free local ACP replay holds prefix, tail and completion behind gates. It emits a running ACP command tool call, then the two real message chunks. The command is a protocol fixture, not an executed shell workload. Projects and turns are created through actual app APIs. SQLite is read-only. No projection or event rows are injected. agent.mjs, client-fixture.ts, fixture-settings.json, provider.ndjson and milestones.ndjson retain the setup and controls. No real account, paid turn, T3 Connect or live T3 home was used.

Commands and real output

From the run's own source clone:

text

1	git fetch origin main
2	git bundle verify ../candidate.bundle
3	../candidate.bundle is okay
4	git fetch ../candidate.bundle

In both detached worktrees:

text

1	vp i --frozen-lockfile
2	Done in 17.5s using pnpm v12.14.0 [baseline]
3	Done in 3s using pnpm v12.14.0 [candidate serial completion]

From each apps/desktop:

text

1	node scripts/build-browser-secret.mjs && node scripts/build-preview-annotation-css.mjs && vp pack
2	✔ Build complete in 719ms [baseline]
3	✔ Build complete in 753ms [candidate]

From each root:

text

1	vp run --filter t3 build
2	[cli] Bundled web app into dist/client
3	vp run: 2/2 successful.

Desktop builds emitted existing import.meta-in-CJS bundler warnings and exited 0. Full output is in install-*.log, build-desktop-*.log, and build-server-*.log. The initial concurrent candidate install failed on a shared Git config lock; the serial completion passed. setup-notes.md records setup failures and the changed approach. No Boat checks, storage-failure probes, repo-wide checks or source tests were duplicated.

Launch and control recipe:

text

1	cua-driver call launch_app '{"name":"PR28221Refresh","creates_new_application_instance":true,"additional_arguments":["/tmp/fun-runs/r_hrgnoyrcibmmw000/out/desktop-loader.cjs","--use-mock-keychain"],"session":"shiv28221refresh"}'
2	python3 out/actions.py setup
3	python3 out/actions.py record
4	python3 out/actions.py release prefix
5	python3 out/actions.py snap prefix
6	python3 out/actions.py release tail
7	python3 out/actions.py snap held

For the candidate paragraph case, background Cmd+R reloads the main client window while the gate remains open, then again after completion. The app maps that key to its main-window Reload command. Both action outputs and the resulting UI/state are retained. The pending Stop case uses stop-race-click.py: it starts a background AX Stop click and releases the normal tail gate from an external 350 ms timer during the click. This arranges pending text without changing the product or replay agent's message/gate behavior.

text

1	python3 out/assert-evidence.py
2	PASS: 140 persisted-state, read-API, reload, UI, cancellation and build assertions

Observed results

The same chat view, prompt and text were used before and after:

text

1	First paragraph.
2
3	This held paragraph appears while the command and turn stay open.

Case	Open turn	Result
Baseline paragraph	Prefix persists; released tail stays invisible. Same run, command running, Stop available.	Full text appears when completion is released. Same run ultimately completes.
Candidate paragraph	Prefix first, then full tail before completion. Same assistant message, same running run and command, Stop available.	Full text stays after completion.
Candidate open-turn reload	Reloaded window 16639 while the prompt remained open.	Full persisted text and same run/message survive; command still running, Stop available.
Candidate completed reload	Reloaded window 16639 after the run completed.	Full text retained, same message/run, nonstreaming.
Candidate full-turn, setting `turn`	Both chunks released, no assistant message/item in DB/API or visible paragraph while the command runs.	Full text appears and remains at completion.
Candidate pending-text UI Stop	Pending DB/API snapshot still has only prefix and the running original run. Cancellation reaches ACP 0.431 s after tail release.	One prompt, one ACP cancel, one interrupted run; one interrupt request/result. Message/item become nonstreaming. Releasing the complete gate later causes no run, message or item changes.

*-state.json includes the real SQLite rows and authenticated GET /api/orchestration/threads/:threadId response. Read-API messages match the stored payloads. Turn items match except the API's explicit outputOmitted:true for workspace-preparation output; assistant text, streaming flags and run identity agree. events.json exports the real consolidated orchestration_events log. Stop has one transition to interrupted; a later interrupted update attaches checkpoint metadata, not a second interruption.

The baseline immediate completion snapshot catches the run's short waiting checkpoint phase, with full text already present and nonstreaming. Its terminal-db-state.json and event log prove the original run then became completed. Candidate final and post-reload snapshots directly show completed.

Recordings personally inspected

All paths below are relative to out/. H.264 MP4s were remuxed with +faststart. These are new captures from the exact builds above. Native milestone screenshots and UI snapshots were inspected, along with the recording frames listed below. Contact sheets contain unchanged video frames in row order; times are in inspected-offsets.json.

MP4	Duration	Controls and inspected offsets
`before/desktop.mp4`	18.443 s	Tail gate 0.109 s, completion gate 17.889 s. At 1, 8 and 17 s only prefix appears with Running and Stop. At 18.25 s full text appears.
`after/desktop.mp4`	50.463 s	Tail gate 5.744 s, held reload returns by 16.484 s, completion gate 29.153 s, completed reload returns by 41.480 s. At 1 s prefix only; 8, 16.7 and 28 s full text with Running and Stop; 42 and 49 s full retained text after completion/reload.
`turn/desktop.mp4`	22.928 s	Both chunks released just before first captured frame, completion gate 11.449 s. At 1 and 10 s no assistant text, Running and Stop; at 13 and 21 s full retained text.
`stop-race/desktop.mp4`	63.077 s	Tail gate 22.820 s, provider cancel 23.251 s, completion gate 38.573 s. At 1 and 22.5 s prefix with Running and Stop; at 24 s interrupted with retained text; at 39.5, 50 and 62 s interruption remains stable after gate release.

Reload offsets use the action output's saved timestamp; gate offsets use wrec's capture-start event. Prefix was already released within 0.223 s of recording startup, so the first frames show the prefix. This does not claim a measured 800 ms delivery deadline.

Milestones: before/{prefix,held,completed}.png; after/{prefix,held,reloaded-held,completed,reloaded-completed}.png; turn/{held,completed}.png; stop-race/{prefix,cancelled,after-release}.png. Each has matching *-ui.json and *-state.json. stop-race/pending-state.json and stop-latency.json prove the pending cancellation setup. assertions.json, video-index.json, build-provenance.json, per-case event exports, filtered traces and helper sources supply the checks behind the recordings.

Unproven

Native iOS/Android/mobile rendering. Not attempted in this desktop-only job.
Natural Antigravity hangs or any provider-hang fix. This is a controlled free ACP replay.
Forced cancellation of an unresponsive provider, crash/storage recovery and queued background-session handoff behavior. Parent owns the relevant probes.
Remote relay/T3 Connect, hosted web, other providers and clients.
Signed release packaging, installer/update behavior and an exact wall-clock idle-delivery deadline.

Cleanup and handoff

All launched test-app and fixture PIDs were checked and exited; no test server remained on the seven test ports. Only our test processes were stopped. Disposable profiles, SQLite homes and workspaces, both build worktrees, the source clone, private Electron app and temporary Applications symlink were removed. No simulator was leased or booted. Only collected output artifacts remain; fun owns final collection/removal of its run directory. cleanup.json records the result.

No comments, posts, uploads, pushes, merges, source edits or child threads were made. The report stays in the requested output folder for the parent to publish and assess.

For each worktree, vp i --frozen-lockfile, then from apps/desktop:

1	node scripts/build-browser-secret.mjs && node scripts/build-preview-annotation-css.mjs && vp pack

From each root:

1	vp run --filter t3 build

Obtain the exact pinned runtime with node candidate/apps/desktop/scripts/ensure-electron-runtime.mjs. Copy its Electron.app using Python shutil.copytree(..., symlinks=True) into the task root as PR28221Refresh.app. Change only the copy's Info.plist CFBundleIdentifier to test.local.pr28221.refresh, and bundle/display name to PR28221Refresh. Ad-hoc sign the copy with codesign --force --deep --sign -. Temporarily symlink it into /Applications/PR28221Refresh.app so cua-driver discovers it. No product bundles are copied over or rewritten.

app-config.json is an external per-case config with root pointing to baseline/candidate, out to the output case folder, port to a distinct loopback port and mode to paragraph or turn. start-fixture.py reads it. In this run the ports were 48120 for baseline, 48130 for candidate with reload, 48160 for full-turn and 48190 for the preferred pending Stop. The fixture control endpoint is port+2.

Resolve the external fixture imports through a temporary out/node_modules symlink to candidate's apps/server/node_modules; it loads only contracts/Effect to drive real APIs. Its PROBE_ROOT selects the tested source and source auth CLI. The actual server is launched by each compiled desktop main.

Before GUI launch, verify fixture-configured in the fixture log and the intended provider/streaming setting in its isolated settings.json. Launch through the background cua-driver command in report.md, always passing --use-mock-keychain. Release attach after backend startup; fixture-ready means the auth and project setup completed. actions.py setup creates a real turn through RPC and selects it in the GUI. Gates control only ACP provider emissions; all app state changes occur through the product.

For open/completed reload use actions.py reload held and actions.py reload completed, followed by state/UI snapshots. For pending Stop, preserve the prefix snapshot's AX token and run stop-race-click.py. Completion stays gated until interruption is proven.

The reports retain hashes and clean source status before and after tests. The worktrees, runtime copy and all auth/state/profile data were deleted at cleanup; the scripts describe the setup and are not an invitation to run against a live T3 home.

Refreshed verification after the November 5 base move. Head d069e2d4fff3e46ab2e9667c48667c1820d35d89, tested baseline 90f0158e60b08946bcaae1df07109a893e7c36af. All nine patches rebased unchanged. Fresh independent base-impact review found no source finding or superseding fix. The sibling-wakeup fix #28204 is now on main.

Boat job j_jtu7mzrzxhzjb6o43uz4, large bx_ucnkq9ry, attempt 1, exited 0 at this exact head. Changed checks passed format, lint, knip, GraphQL, three affected typechecks and 72 tests. Affected projection, ingestion, provider-session, turn-start and history-paging tests passed 200 cases. Client thread-sync and RPC-session tests passed 65. Total: 337 passing tests.

Commands:

bash

1	set -euo pipefail
2	vp i --frozen-lockfile
3	vp run check:changed 90f0158e60b08946bcaae1df07109a893e7c36af

Physical corex used Node 26.12.1 and the clean exact-head source server with isolated real file-backed SQLite databases and a free gated ACP fixture. A bounded private 16 MiB tmpfs filled to zero free blocks caused a real idle SQLite write failure. Independent writes also failed with ENOSPC. After restoration, provider metadata persisted at sequence 28 before held full text at sequences 29/30, proving ingestion continued before the retry. Both text representations remained streaming while the original prompt/run stayed open. No new text or completion triggered the retry.

A second server was SIGKILLed with the idle tail still pending, then restarted with the same isolated database and automatic continuation disabled. The prefix survived, the original run was cancelled once, both message and cancelled item were nonstreaming, and the unpersisted tail was lost. This is not crash durability for buffered text.

Runtime preparation and commands:

bash

1	# Install dependencies in the source checkout first.
2	vp i --frozen-lockfile
3	# The external verifier resolves the owning server package's dependencies.
4	ln -s /home/shivam/Developer/.state/issue-watch/worktrees/28175/apps/server/node_modules /tmp/t3code-28221/node_modules
5	# Create the isolated output directories before running.
6	unshare --user --map-root-user --mount sh -c 'mount -t tmpfs -o size=16m tmpfs /tmp/t3code-28221/disk-full/storage && exec /home/shivam/.local/share/vite-plus/js_runtime/node/26.12.1/bin/node /tmp/t3code-28221/disk-full.ts'

Supplementary Boat j_6iymk6qeoimndr4bivr5, large worker bx_vgrf6wjf, attempt 1, also finished with exit 0 on this exact head. It passed another 110 tests: 17 history-merge/RPC-client, 16 Claude SDK runner, 51 selected Claude MCP/timeout, 23 desktop auth/bootstrap, and 3 pruned-cursor tests. Total across both jobs: 447 passing tests. The adapter/cursor filters excluded 292 tests, which were not run in this supplementary job. Exact-head desktop/server/web 0.1.7 recording is still pending. Prior fc00 recordings are historical. Main subsequently added an Antigravity-only 15-minute inactivity watchdog and Codex sharing-limit recovery; neither supplies the missing 800 ms idle delivery. Natural Antigravity hangs remain unverified. Native mobile, remote relay/T3 Connect, forced cancellation, signed packaging and automatic restart continuation also remain unverified.

Fresh exact-head client evidence for head d069e2d4fff3e46ab2e9667c48667c1820d35d89, tested baseline 90f0158e60b08946bcaae1df07109a893e7c36af. These new T3 0.1.7 builds and recordings replace the older fc00 captures as evidence for this head. I inspected the recording frames showing the trigger and before/after results, open/completed reloads, full-turn control and stable cooperative interruption.

Before: main retains only the prefix while the tail is held, then shows full text on completion.

After: tail released at 3.142 s appears while the same command/run/prompt stay open, survives open-turn reload, completes at 20.916 s and remains after completed reload.

https://github.com/user-attachments/assets/bb1c7daa-84d7-46b7-8b23-9701c5ff5800

Full-turn control: both chunks remain buffered until completion at 7.555 s.

https://github.com/user-attachments/assets/0637bb63-0ae6-453b-bea8-720fcc961670

Pending-text UI Stop: tail released at 4.852 s, then one cooperative interruption. Late completion at 8.094 s does not reopen the turn.

Same-view held snapshots:

PR28221 fresh macOS held paragraph and reconnect evidence

The controlled desktop cases pass for candidate d069e2d4fff3e46ab2e9667c48667c1820d35d89 against baseline 90f0158e60b08946bcaae1df07109a893e7c36af. This run supplies evidence to the parent of https://github.com/pingdotgg/t3code/pull/28221. It does not assess live PR readiness.

Physical shiv, arm64 Mac mini, macOS 27.0.1 build 26A434. Both fresh server/web/desktop builds report T3 0.1.7. Electron 44.10.1, embedded Node 24.22.1, Chromium 152.0.7977.169. Fixture/build host Node v26.12.0. Full versions and clean source status are in build-provenance.json and each case's electron-versions.json.

What was seen

All cases use the same chat view, prompt, running ACP command and two chunks. The prefix is First paragraph. followed by a paragraph break. The unfinished tail is This held paragraph appears while the command and turn stay open. Completion has a separate gate.

Case	Observed result
Baseline paragraph	Prefix appears first. After tail emission, only the prefix remains visible and persisted while the original run and command remain running and Stop is available. Completion is held for 5.373 seconds after tail release. Full text appears at completion.
Candidate paragraph	Prefix appears first, then full tail while the same run, message, command and ACP prompt remain open. Stop stays available. Completion retains full text.
Candidate open-turn reload	Background Cmd+R reloads the same window and Electron webContents. Full persisted text, original run/message and running command survive. Stop remains available. A new actual RPC WebSocket renews the thread subscription from a nonzero sequence.
Candidate completion after reconnect	Releasing completion after that reload sends a live `run.updated` event with status `completed` to that renewed subscription. The same client changes to the completed UI without another reload.
Candidate completed reload	Full text and original run/message remain, with nonstreaming state and no Stop.
Candidate full-turn mode `turn`	Both chunks are emitted but no assistant message/item exists in SQLite, API or UI while the turn remains open. Full text appears at completion.
Candidate cooperative Stop	The pending read-only DB/API snapshot follows actual tail emission and precedes the UI's `thread.stop` RPC. One Stop produces one ACP cancel and one transition to interrupted. Full text is retained with nonstreaming state. Opening the completion gate later does not change the run, messages or turn items.

assertions-output.txt contains the real exit-0 output:

text

1	PASS: 167 persisted-state, read-API, reload, UI, cancellation and build assertions

The count includes DB/API agreement, message and run identity, running command and Stop visibility, paragraph/turn behavior, both reloads, cancellation counts, terminal stability, exact build provenance and passive socket observations. assertions.json records every assertion. assert-evidence.py is retained.

Real RPC reconnect and completion

Passive Electron debugger Network observations are in after/rpc-socket.ndjson. The observer only reads Network events. It does not run page JavaScript, replace sockets, inject behavior or change application code. Handshake headers were not recorded; socket URL queries were redacted.

02:28:55.675	Original client socket `7934.293` opens.
02:29:21.582	During the open turn, reload opens socket `7934.601` in the same webContents 1.
02:29:21.647	That socket sends request 14, `orchestration.subscribeThread`, for original thread `d8bc330e-e85d-4073-838c-b39fa4f9f033`, with `afterSequence: 30`.
02:29:21.654	Request 14 receives `kind: synchronized`.
02:29:35.203	The fixture releases completion, after the open-turn reload and held screenshot.
02:29:35.337	Request 14 receives a live frame containing `run.updated`, status `completed`, for original run `run:thread:d8bc330e-e85d-4073-838c-b39fa4f9f033:ordinal:1`.
02:29:38.959	The later completed-state reload opens socket `7934.898`.

after/reconnect-trace.json retains the decoded request, synchronization and live event frames. Completion is present inside the current RPC batched values, not inferred from static SQLite. The compiled current client/server use their real RPC framing path. This does not claim a large split-frame stress test or a network outage test.

The connected local desktop view did not expose a separate Reconnect button. Source inspection found the composer Reconnect action is conditional on an unavailable environment and hidden during active reconnection. No outage was injected to expose that separate action. The supported Reload action was exercised twice. Offline-only manual reconnect remains unproven.

Pending Stop timing

All times below are UTC on shiv. The Stop helper begins a background AX action and uses an external 350 ms timer to release the ordinary tail gate while that action is in flight. It waits for the fixture's emission acknowledgment before reading state. This changes fixture timing only.

Milestone	UTC time
Tail gate release	02:32:55.489
Provider writes tail chunk	02:32:55.491
Real read-only DB sample, API also still prefix	02:32:55.494
Client sends its one `thread.stop` RPC	02:32:55.902
Provider receives its one `session/cancel`	02:32:55.925
Completion gate later opens	02:32:58.731

The sample contains the original running run, running command and prefix-only streaming assistant. It follows emission by 3 ms and precedes the Stop RPC by 408 ms. Tail release to ACP cancel is 0.436 seconds. See stop-race/pending-state.json, stop-latency.json, rpc-socket.ndjson, provider.ndjson, events.json and the cancelled/after-release snapshots. This proves cooperative cancellation with text pending before the idle flush. It makes no claim about forced cancellation or a naturally frozen provider.

Fresh build commands and provenance

build-recipe.md retains the setup and launch commands. A separate source clone and two detached worktrees were used under this task folder. The parent corex worktree was neither changed nor run. The supplied bundle verifies, requires the exact baseline and advertises the exact candidate. Its lack of a HEAD ref required an explicit ref on fetch, recorded in the logs.

Command	Real final result
`git -C source bundle verify ../candidate.bundle`	`../candidate.bundle is okay`
`vp i --frozen-lockfile`, baseline	Exit 0, `Done in 11.4s using pnpm v12.14.0`
`vp i --frozen-lockfile`, candidate	Exit 0, `Done in 10.8s using pnpm v12.14.0`
In each `apps/desktop`: `node scripts/build-browser-secret.mjs && node scripts/build-preview-annotation-css.mjs && vp pack`	Both exit 0. Final build completion lines report 450 ms baseline and 427 ms candidate.
At each root: `vp run --filter t3 build`	Both exit 0, `[cli] Bundled web app into dist/client`, `vp run: 2/2 successful.`
`python3 out/provenance.py`, after captures	Exit 0, `PASS: source and all compiled desktop/server/client hashes unchanged`

install-*.log, build-desktop-*.log and build-server-*.log contain full output. Desktop bundling reports unresolved optional x11 and Effect import.meta in CJS warnings, then succeeds. No source tests, Boat jobs, disk-full or crash probes were run.

Both source worktrees had empty git status --porcelain before and after capture. build-provenance.json and independently recomputed build-provenance-final.json contain exact commits, versions and SHA-256 hashes of all compiled desktop/backend/web files. The comparison passed.

Compiled file	Baseline SHA-256	Candidate SHA-256
desktop `boot.cjs`	`7264a39eb496414ba9ad8d25adde7b772d7abaed25d3e5b331ebdd8792d38128`	Same
desktop `main.cjs`	`dc8f959f8db3037298bc4a975e21c7bc3891e88671fac183c90a08c4ef583d42`	Same

The disposable runtime launches real compiled boot.cjs, main and preload. The compiled desktop main launches the matching freshly compiled backend/web. The external loader isolates Electron paths and explicit T3CODE_HOME/TMPDIR; the actual HOME variable stays /Users/shivam-mini. Every launch passes --use-mock-keychain. GUI actions use background cua-driver and recordings target only the app window with wrec, without cursor or audio.

Only synthetic data and a free local ACP command fixture were used. The running command is an ACP protocol fixture, not a shell workload. Projects and turns are created through actual app APIs. SQLite is opened read-only. No projection/event rows or built application logic were patched. No paid provider turn or login was used.

Recordings personally inspected

Paths are relative to this out/ directory. The four finalized H.264 MP4s were remuxed with +faststart. I inspected native milestone screenshots and unchanged frames extracted from each recording. inspected-offsets.json, contact sheets and video-index.json retain the reviewed offsets and gate timing.

File	Duration	Inspected offsets and result
`before/desktop.mp4`	12.055 s	2.5, 6, 8, 11 s. Prefix first; prefix only with Running and Stop after tail release at 3.125 s; full text after completion at 8.498 s.
`after/desktop.mp4`	29.593 s	2.5, 5.5, 11.5, 20, 23.5, 28.5 s. Prefix first; full held text after tail at 3.142 s; same open state after reload; full completed text after completion at 20.916 s and after completed reload.
`turn/desktop.mp4`	12.322 s	2.5, 6.5, 9.5, 11.5 s. Both chunks emitted but buffered before completion at 7.555 s; full text afterward.
`stop-race/desktop.mp4`	13.808 s	3, 4.75, 6.5, 9.5, 12.5 s. Prefix with Running and Stop; tail release at 4.852 s, then interrupted full text; still interrupted after late completion at 8.094 s.

Milestones are before/{prefix,held,completed}.png, after/{prefix,held,reloaded-held,completed,reloaded-completed}.png, turn/{prefix,held,completed}.png, and stop-race/{prefix,cancelled,after-release}.png. Each has matching *-ui.json and *-state.json. Per-case events.json holds real event rows. Read-API messages match persisted payloads. Turn items match except the API's explicitly marked outputOmitted command output.

Two preliminary captures are retained as setup records, not primary evidence. before-initial/ was repeated for a clearer tail-hold interval. stop-initial/ was repeated because its DB sample preceded the tail emission trace by 1 ms. All claims above use before/, after/, turn/ and stop-race/. Prior-run files under helpers/ are historical helper inputs only.

Unproven

Natural Antigravity hangs and real-provider behavior. This was a controlled free ACP fixture.
Native mobile, relay/T3 Connect, hosted web and other providers.
Forced cancellation of an unresponsive provider, automatic restart continuation, storage/crash recovery or disk-full handling. The parent owns relevant probes.
Offline-only manual Reconnect UI, network-outage recovery and large split-frame stress. Actual reload, renewed RPC subscription and subsequent live completion are proven.
Signed packaging, installer/update behavior and an exact idle-flush latency bound.
Live PR checks, review resolution, mergeability and readiness. The parent owns these.

Cleanup and handoff

All captured own app, backend, fixture and provider PIDs exited. All 12 test ports are closed. Disposable SQLite homes, Electron profiles, workspaces, source/build worktrees, copied runtime, local bundle and Applications symlink were removed. No simulator or mobile device was used. The parent corex bundle/worktree and fun-owned task files were preserved. cleanup.json, cleanup-processes.json, ports-after-cleanup.json and cleanup-output.txt retain the checks.

No product source edits, uploads, posts, comments, pushes, merges or child threads were made. The parent receives result.json, this report, helper sources and collected evidence through fun.

Fresh current-head corex storage/restart proof, reproducible verifier sources and 447 passing tests: https://github.com/pingdotgg/t3code/pull/28221#issuecomment-6647450270.

Fresh independent Codex evidence review found no material findings. It confirmed build provenance and final hashes, DB/API/event/UI agreement, pending-text cancellation timing, and actual reconnect followed by live completion. Primary frame inspection and uploaded-byte verification are complete. Reproducer/assertion sources: https://github.com/pingdotgg/t3code/pull/28221#issuecomment-6648408685. Natural Antigravity hangs and the named unverified clients/routes remain unproven.

Reproducer and assertion sources for the fresh macOS client evidence at head d069e2d4fff3e46ab2e9667c48667c1820d35d89, baseline 90f0158e60b08946bcaae1df07109a893e7c36af. These external helpers isolate test state, drive the free ACP replay and passively observe RPC traffic. They do not patch product behavior.

1	# Fresh macOS build and capture recipe
2
3	Task root `/tmp/fun-runs/r_jmtzudwa8f7q0000`. Only independent clones/worktrees in this folder were used. The explicit task instruction places disposable worktrees under this task folder.
4
5	```sh
6	git clone --shared --no-checkout /Users/shivam-mini/Developer/t3code source
7	git -C source remote set-url origin https://github.com/pingdotgg/t3code.git
8	git -C source fetch origin main
9	scp corex:/tmp/t3code-28221/candidate.bundle ./candidate.bundle
10	git -C source bundle verify ../candidate.bundle
11	git -C source fetch ../candidate.bundle refs/heads/issue-watch/28175:refs/heads/test-candidate
12	git -C source worktree add --detach ../baseline 90f0158e60b08946bcaae1df07109a893e7c36af
13	git -C source worktree add --detach ../candidate d069e2d4fff3e46ab2e9667c48667c1820d35d89

The bundle has no HEAD ref, so the initial fetch without a ref failed and was replaced with the explicit ref above. bundle-verify.log proves its prerequisite and candidate.

In each worktree, serially install vp i --frozen-lockfile. In each apps/desktop, run node scripts/build-browser-secret.mjs && node scripts/build-preview-annotation-css.mjs && vp pack. At each root, run vp run --filter t3 build. All final installs/builds exited 0. The first baseline desktop invocation wrote to the execution transcript; it was repeated with a file log for collected build evidence. No tests were rerun or added.

Run node candidate/apps/desktop/scripts/ensure-electron-runtime.mjs, copy that runtime's Electron.app with symlinks preserved into the task's PR28221D069.app, set its bundle/display name and a unique test bundle id, ad-hoc sign, and temporarily symlink it into /Applications/PR28221D069.app for background cua discovery.

app-config.json selects root, output folder, loopback port and streaming mode. The cases are baseline before on 48220, candidate after on 48230, turn on 48260 and stop-race on 48290. Fixture control listens on port+2. Set out/node_modules to candidate apps/server/node_modules solely for the external API fixture imports. python3 out/start-fixture.py configures the local ACP provider before app launch. Background launch:

1	cua-driver call launch_app '{"name":"PR28221D069","creates_new_application_instance":true,"additional_arguments":["/tmp/fun-runs/r_jmtzudwa8f7q0000/out/desktop-loader.cjs","--use-mock-keychain"],"session":"shiv28221d069"}'
2	python3 out/actions.py release attach
3	python3 out/actions.py setup
4	python3 out/actions.py record
5	python3 out/actions.py release prefix
6	python3 out/actions.py snap prefix
7	python3 out/actions.py release tail
8	python3 out/actions.py snap held

Use separate wall-clock observation holds to make recording milestones legible. Baseline tail was held 5.373 seconds before completion; candidate tail was held 17.774 seconds including reload. These are GUI evidence holds, not source test sleeps or assertions on exact latency. Only then release complete, capture completion and stop recording. For candidate, invoke actions.py reload held before completing and actions.py reload completed afterward, capturing state/UI after each.

The external loader requires real compiled dist-electron/boot.cjs, which loads compiled main and preload. That main launches its corresponding compiled backend and bundled web. It isolates Electron paths, explicit T3CODE_HOME and TMPDIR; actual HOME remains unchanged. It adds only passive Electron debugger Network-domain observations. It does not evaluate page JavaScript or change socket, renderer, adapter, streaming or persistence logic. Handshake headers are not saved and socket URL queries are redacted.

The fixture only emits ACP messages through ordinary stdio and gates prefix, tail and completion. Its tail-emitted acknowledgment allows the pending Stop DB/API sample to occur after the chunk has been written, before cancellation. stop-race-click.py uses a background AX Stop action while an external 350ms timer releases the tail. The control thread waits for emission acknowledgment, then reads real state. No product data is written except through product APIs. All SQLite access is read-only.

export-state.py saves real event rows and captures process ancestry for cleanup. assert-evidence.py checks stored/read-API/UI/run/message/command identities, cancellation counts and passive reconnect observations. process-videos.py remuxes finalized wrec captures to MP4; inspect-videos.py saves unchanged frame contact sheets. The final source/build hashes are recomputed and compared before deleting disposable builds.

Refreshed macOS proof for the base move. On the same view, baseline keeps the trailing paragraph hidden until completion; the candidate shows it while the original provider prompt, run and command remain open. Reload, live completion after resubscription, full-turn buffering and cooperative pending-text Stop pass. New fresh-session and history-budget cases pass too.

This tests an integrated tree, rather than claiming these recordings came from the exact PR checkout. Baseline is clean a09aef3287d29f74e2270fae05ab0cef8202cfa1; candidate is that base plus only the four-file patch from 90f0158e60b08946bcaae1df07109a893e7c36af..d069e2d4fff3e46ab2e9667c48667c1820d35d89. All four candidate files match the PR head byte for byte. Candidate indexed tree c66e3c541d67cf9a9266032a618b0549c8837447; patch SHA-256 4acf9a26e6675ab0bb26faa83beb402c439b6c7af30fa60b4dd1fce8be694967.

Physical shiv Mac mini, macOS 27.0.1 arm64, T3 server/web/desktop 0.1.7, Electron 44.10.1, embedded Node 24.22.1. Fresh baseline and candidate desktop main/preload, server and bundled web builds exited 0. Host Node 26.12.0/pnpm 12.14.0. Free gated local ACP fixture, isolated SQLite and profiles, unchanged HOME, test data only. Own disposable Electron runtime used mock keychain. No real provider, paid turn or account login.

Case	Observed result
Paragraph mode	Candidate full tail is persisted and rendered while same run and command remain running. Baseline only shows prefix until completion.
Reload/reconnect	Open reload keeps the same message and running command. Actual new RPC socket renews subscription 15 from sequence 31, synchronizes and receives live completion on that subscription. Completed reload keeps full text.
Full-turn mode	No assistant message/item in SQLite/API/UI before completion; full text arrives at completion.
Pending-tail Stop	Provider tail emission, prefix-only DB/API sample, actual UI Stop RPC, ACP cancel, then first full-tail nonstreaming write. One interrupt transition; late completion never reopens it.
Queued fresh session	Fresh-context run waits behind original; then starts a distinct session/native thread without old conversation content or handoff. Its prefix and idle tail render while open.
History-heavy stopped reload	27 actual runs, 54 messages, 86 stored items. Snapshot plus two older pages recover 83 conversation entries exactly once. Reload and late release preserve stopped state.
Oversized controls	14 actual runs, 200 long-path changed files per turn 2..14. Checkpoints 1,996,665 bytes; control 2,053,732 bytes forces revised half-budget branch. Snapshot retains final user/assistant/interrupt/checkpoint; two pages recover 44 conversation entries exactly once. Reload remains stopped.

Verification commands and results:

1	python3 out/assert-evidence.py
2	PASS: 167 persisted-state,read-API,reload,UI,cancellation and build assertions
3	python3 out/assert-supplemental.py
4	PASS: 42 fresh-session,history,control-budget and pending-Stop assertions
5	python3 out/record-provenance.py
6	PASS: source,indexed tree,patch,desktop/server/web and runtime hashes unchanged

These are 209 evidence assertions, separate from source unit tests. I inspected all seven recording contact sheets and checked source/patch hashes against the actual PR head. Final rebuilt artifact hashes were recomputed unchanged. Build recipe used vp i --frozen-lockfile, desktop browser-secret/annotation CSS scripts and vp pack, then root vp run --filter t3 build. The latter bundles the web app into the server.

Pending Stop ordering, derived from provider/DB/API/RPC traces:

6	"tailToCancelSeconds": 0.2200000286102295
7	}

Actual Stop RPC 21:27:29.424Z precedes ACP cancel 21:27:29.456Z and first full-tail persistence 21:27:29.466Z with streaming=false. No full-tail streaming write precedes Stop. Observed completion after reload uses renewed RPC request 15 on the new socket, without another reload.

Unverified: natural Antigravity hangs and real-provider behavior, native mobile, relay/T3 Connect, separate remote browser, forced cancellation, signed installers, offline manual Reconnect/network outage recovery, split-frame stress and precise latency bounds. This does not claim to fix the provider keeping a prompt open. Current-source storage/crash proof remains separately linked in the PR; this client job did not repeat it.

Cleanup passed: all 26 captured own PIDs exited, 18 ports closed, disposable apps/builds/profiles/SQLite homes and worktrees removed. Fun-managed evidence is retained. Source checks and live readiness are reported separately.

Reproducer and assertions for the integrated a09+d069 macOS evidence. These scripts drive isolated real server/desktop state through gated ACP, without changing product source.

Integrated verification passed after the base move. PR head remains d069e2d4fff3e46ab2e9667c48667c1820d35d89. A disposable checkout of main 25b53299b75d4d8d1d0667ad47e9cfed3749776e plus the exact four-file PR patch produced indexed tree a5402a5bac0d7679af4571bb533ce1712885bae3. All four hashes match the PR head. No branch/source implementation change was needed.

Local verification in the corex-hosted workspace container, Linux 7.2.1-070201-generic, Node v26.12.1. Dependency install used vp i --frozen-lockfile and exited 0. The previous Boat job j_dr7jydnt3dfyi3p5gd2y failed before commands with VM refused: state starting; no test pass is attributed to it. Local execution was the alternative.

756 focused tests passed: 579 ingestion/persistence/session/projection/SQLite/client-sync/desktop-config cases, 3 fresh-session integration cases, 4 Claude effort/Ultracode adapter cases, and 170 model/catalog/MCP/replay/query-cache/runtime cases. check:changed separately passed 72 test executions, format, lint, knip, GraphQL and three affected typechecks. It compared against the pinned main above. Filtered tests are not counted as passes. All commands exited 0.

The current-base client proof is in https://github.com/pingdotgg/t3code/pull/28221#issuecomment-6670473078 and its sources in https://github.com/pingdotgg/t3code/pull/28221#issuecomment-6670477360. It is labeled as a09 plus the d069 patch, rather than relabeled as a 25b build. The later delta changes Claude selection/effort, MCP resolution, shared query persistence and unrelated mobile/PR paths. Those relevant code paths passed the supplemental tests; they do not change the four PR files or the controlled ACP text/reload path.

The control-budget recording exercises the revised half-budget floor, including its 915-byte interrupt dependency reserve. An independent review initially cited the old formula from the PR checkout; the tested main already subtracts that reserve from half the budget. Running the actual current buildBoundedThreadProjection on the captured full projection reproduces the exact five bounded item IDs. The computed floor is 523,373 bytes, while the ordinary remainder is negative. The paging function is identical between a09 and 25b.

I inspected all seven recording contact sheets. All nine uploaded MP4/PNG assets were downloaded and verified byte for byte against the captures. Raw provider traces are excluded because their test MCP configuration contains ephemeral bearer values; the published sources use no captured credentials.

Natural Antigravity hangs, real-provider behavior, native mobile, relay/T3 Connect and the other limits listed in the PR remain unverified. Existing exact-head corex ENOSPC/retry/crash evidence is unchanged; no new storage semantics changed in this base delta. This comment is evidence, not a merge authorization.

Fresh independent Codex follow-up review resolved all evidence findings: integrated checks passed, the tested-base half-budget calculation is correct, and public excerpts/sources contain no captured credentials. It independently verified the integrated tree, five published source files and all nine uploaded asset hashes. No new material finding.

Refreshed the moved-base review and integrated source verification. PR head remains d069e2d4fff3e46ab2e9667c48667c1820d35d89; tested main is c7537d026492d42c2fb9fd400577f88767e8d774, covering the wake's 79ee39f base as well. All four PR files remain unchanged on main. No source edit or rebase was needed for compatibility. Main still lacks idle delivery; no superseding merged fix or Julius takeover was found.

Applied the exact four-file PR patch to a disposable main checkout on physical corex. Its indexed tree 76d3593833a51e9837253445ab5d95dee284fc5f equals Git's clean merge tree for this head and main. The patch SHA-256 is 4acf9a26e6675ab0bb26faa83beb402c439b6c7af30fa60b4dd1fce8be694967. Source hashes and indexed tree were recomputed after verification and remained identical.

785 focused tests passed across 18 files. check:changed separately passed 72 adjacent test executions, format, lint, both knip passes, GraphQL and three affected package typechecks. All commands exited 0. This covers the PR filter/ingestion, provider ingestion and Claude catalog/effort changes, usage-limit filtering, RPC closed-socket behavior, subscription ACK windows, supervisor reconnect, shell migration/resume and warm-cache thread cursor resume. Existing exact-head storage/crash evidence remains correctly attributed to its original build.

A fresh independent Codex review found no new source defect. It requested the transport tests above and one rebuilt real-client held-tail/reload/resubscribe pass because main changed count-windowed subscriptions, RPC teardown and resume. That app refresh is running separately; these source checks do not establish its result. The seven earlier macOS recordings remain evidence for a09 plus the exact patch, not c753 builds. Natural Antigravity hangs remain unverified.

Final live-base read advanced to 7bc2a40ced9094e2b5fd2f076e1bfeab734f8aed. Its two commits after c753 change PR mentions and PR composer context selections. Reviewed all 41 changed paths and the chat/contract/shared-package intersections; they do not change assistant rendering, transport, orchestration or storage. No additional verification is needed for those two commits. The rebuilt-client transport refresh remains pinned to c753 plus the exact patch, with that attribution preserved.

https://github.com/user-attachments/assets/a2974ebe-3968-40c0-a0fe-9ca3a32a21c6

Refreshed real-client transport evidence for PR head d069e2d4fff3e46ab2e9667c48667c1820d35d89 integrated with main c7537d026492d42c2fb9fd400577f88767e8d774. This is the exact four-file patch on c753, indexed tree 76d3593833a51e9837253445ab5d95dee284fc5f, not a recording relabeled as a d069-only build. All four patched files match the PR head byte for byte.

On physical shiv, macOS 27.0.1 arm64, freshly rebuilt T3 desktop/server/web 0.1.7 with Electron 44.10.1, the held paragraph appears while the original command and turn stay open. Actual Cmd+R replaces the RPC socket; full streaming text survives, completion arrives on the replacement subscription without another reload, and completed reload retains full text. The free gated local ACP fixture drives the real backend, database and client. Product code and persisted projections were not instrumented.

Frames from that recording, in chronological order:

assert-transport.py passed 86 persistence, read-API, UI and replacement-subscription assertions. These are evidence assertions, separate from the 785 focused tests and 72 adjacent check executions. The primary agent independently reran all 86 assertions, verified each patched file against the PR commit, checked the patch hash and unchanged build manifests, and inspected the recording frames.

Both streaming representations contain the prefix at sequences 28/29 and the full idle tail at 30/31, before final text at 33/34. The command runs from sequence 27 to 36; the original run completes at 46. Replacement subscription 14 resumes the original thread after sequence 31, receives seven ordered Chunk frames, one synchronization and six event-bearing frames, and ACKs all seven. The full final assistant turn item is persisted; its wire text is omitted through normal message-body deduplication.

All build, assertion and provenance commands exited 0. Captured app and fixture PIDs exited, ports closed, disposable source/builds/profiles/state removed and the background CUA session ended. No simulator or paid provider was used.

The earlier a09 before/after, full-turn buffering, pending Stop, fresh-session and history recordings keep their original attribution. This refresh targets only main's later transport changes. Exact-head corex storage failure/retry and crash evidence remains separately attributed.

Unproven: natural Antigravity hangs and real-provider behavior, forced network outages, unresponsive-provider cancellation, signed packaging, other providers and connection routes. No new baseline or other-device recording is claimed. device-route maps the two changed production files to tests only; the issue names no specific OS device. The Mac recording supplies real-app proof for the reported visible behavior.

All helpers use literal `/tmp/fun-runs/r_51lkxvvkttvezq00`; replace that root consistently for a new run. Keep the user's HOME unchanged. The app must use mock keychain. Private fixture output goes in work/after and must not be uploaded wholesale.

source-provenance.json must first be regenerated from the actual base, patch hash, indexed tree and four byte comparisons to the pinned PR head. Do not trust an old manifest after altering the source. record-provenance.py records the initial complete manifest and requires equality on its second call. Reproduction build commands and their real logs are retained beside this file.

case.py open after starts a free local ACP fixture, launches the compiled actual desktop with isolated state and mock keychain, waits for configuration/ready gates and selects the real thread. run-paragraph.py after records the initial view, releases prefix then tail, samples both persistence representations/API/UI, reloads via background CUA, releases completion, reloads again, exports events and closes app/fixture. Its fixed holds make GUI milestones readable; assertions depend on actual event/state order rather than elapsed-time thresholds.

derive-transport.py must run while private traces still exist. It exports only selected/redacted evidence. assert-transport.py runs offline after cleanup. The loader's Electron debugger subscription is passive Network observation only. Do not copy provider.ndjson, full rpc-socket.ndjson, userdata, credentials or session URLs into public artifacts.

5	Fresh independent evidence review resolved BI1 and confirmed BI2. It inspected the MP4 frames, state/events, socket excerpts, verifier source, provenance, redaction and cleanup. All 86 artifact hashes matched. The only finding, N1, was the chunk-count wording corrected above; the seven frames include one synchronization frame. No source defect or additional verification requirement was found.

7	The same review examined main `7bc2a40ced9094e2b5fd2f076e1bfeab734f8aed..c52df24d285a072ad9c3f7ab5b3656c0be1cb0f5`. Its PR features and iOS composer flushing leave streaming, ingestion, storage and transport unchanged. No extra build or recording is warranted for that range. The live main branch ref remains c52. The PR API's older base snapshot `935818e422f9b58c46e14d70f4ef386fa3575105` is an ancestor of the already tested c753 base, not an unreviewed later change. Git reports a clean current merge; the four patch files in that tree match the tested and recorded files byte for byte.

MmacroscopeappBotapproved these changes · review dismissed4d ago

The batching integration is pushed at c2eba7006f04559a2c998b307a1e84ae16f080ba, based on 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0. It retains main's snapshot batching and queues idle delivery as an ordered consumer control. The idle write commits before delivery bookkeeping. The old semaphore is removed.

All six PR files are byte-identical between the reviewed 95b4a9e9ab7f2d4aa80215f07dfa59a56438f09f and current head, verified with git diff --exit-code. The mechanical rebase adds guarded automatic settlement and unrelated web changes. The current-head settlement cases and required checks cover that update.

Fresh independent source review found two items. R1 is resolved by keeping backoff per snapshot and the ten-minute warning cap per run, across unrelated successes and failures. R2 is resolved by extending the retry case through real EventSink/SQLite: a deferred foreign-key constraint makes COMMIT fail after the body succeeds, with no publication or persisted text; repair and restore permit retry and final persistence. A second fresh reviewer resolved both, with no new findings. The warning extension fails before the fix and passes afterward.

The constraint test explicitly rolls back the still-open transaction as connection repair. It does not claim automatic recovery from every COMMIT error. The existing driver's handling of constraint/busy errors that leave a transaction open is unchanged.

Exact-head storage transcripts and verifier source follow separately. The fresh Mac comparison is running. This is not a ready report. Natural Antigravity hangs remain unverified.

Real isolated SQLite verification on physical corex at c2eba7006f04559a2c998b307a1e84ae16f080ba, base 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0, Node 26.12.1. Both commands exited 0. These use a free gated ACP replay through the source server, not a stubbed persistence layer.

A private 16 MiB tmpfs returned ENOSPC for the server and an independent one-byte write. After space was restored, ordinary provider metadata persisted at sequence 28 before held text retried at 29/30 in both streaming representations. The original run and provider prompt remained open until the assertions passed.

The crash case SIGKILLed only its own server while the paragraph was pending, then restarted the same isolated home with continuation disabled. The durable prefix survived, the original run became cancelled and both records stopped streaming. The unpersisted tail was lost.

The server's local log clock differs from the explicit UTC milestones and persisted events. All captured server PIDs exited; private database keys and traces are removed after export. Natural Antigravity hangs, automatic continuation and recovery from every possible COMMIT error remain unverified.

Reproduction source for the exact-head physical-corex SQLite probes at c2eba7006f04559a2c998b307a1e84ae16f080ba, base 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0. The companion transcript records the successful assertions. The physical-host dev-tmp path aliases this T3 session's /tmp/test-pr/t3code-28221 folder. Only a private bounded filesystem is filled.

Commands:

1	ssh corex 'unshare --user --map-root-user --mount /bin/bash /home/shivam/Developer/.state/dev-tmp/test-pr/t3code-28221/runtime/run-disk-full.sh c2eba7006f04559a2c998b307a1e84ae16f080ba 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0'
2	ssh corex '/bin/bash /home/shivam/Developer/.state/dev-tmp/test-pr/t3code-28221/runtime/run-crash.sh c2eba7006f04559a2c998b307a1e84ae16f080ba 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0'

The probes assert a clean source tree and exact commit before starting. They create isolated homes and synthetic projects, capture their own server PIDs, and shut those processes down. No live T3 database is written. Natural Antigravity hangs remain unverified.

Keep idle ticks from ending ingestion ahead of queued provider events.

In paragraph mode, a completed snapshot can leave a tick scheduled. If OpenCode finishes a nested continuation before its queued events reach the consumer, the pending-work probe can return false. The tick can then stop ingestion before the continuation output is delivered.

✅ Confirmed as addressed by @shivamhwp

Fixed in 9a3ac59da77de24374422a5d834d3bafd891edd5. The stop decision now retains the last successfully stored root snapshot's pendingBackgroundWork flag. A false live probe cannot override that ordered true snapshot. Idle ticks still flush held text, but cannot end ingestion until the root's clearing snapshot arrives after the nested continuation output. The provider stream preserves that order, and commit-batch barriers wait for earlier writes.

Both existing nested OpenCode regressions failed before this guard and pass with it, including batching enabled and disabled. Final-head CI now passes, including Server 1 and Server 8. A fresh independent source review found no remaining issue in this path. Evidence: https://github.com/pingdotgg/t3code/pull/28221#issuecomment-6678833267.

@shivamhwp I checked 9a3ac59. On the normal completion path, the stop check keeps ingestion open while the last stored root snapshot reports pending work. It checks that flag before the live probe.

Your evidence reports that the OpenCode replay passes with batching enabled and disabled. I did not rerun the tests.

If you found this review helpful, would you consider giving us a shout-out on X?

Thank you for using CodeRabbit!

fix(server): keep nested background ingestion open until the root snapshot settles9a3ac59

Pushed the CI regression fix at 9a3ac59da77de24374422a5d834d3bafd891edd5, based on 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0. The added stream merge let OpenCode's live pending-work probe advance beyond the provider events the consumer had processed. That could stop ingestion before a nested child's continuation text arrived. The consumer now retains the last stored root snapshot's ordered pending-work flag before consulting the live probe. Ownership loss, interruption and stream end retain their existing exit paths. Other adapters omit this flag and keep their existing probe behavior.

The existing nested-background replay failed on c2eba70 and passes with the fix. Both OpenCode files pass all 29 cases, including separate runs with batching disabled and enabled. Another 105 orchestration/streaming tests and 70 Claude/Codex/recovery replays pass. Required local check:changed passes, including 96 tests and three affected package typechecks. A fresh independent reviewer found no issue in the repair. This is a code fix for the CI failure, not a rerun of the unchanged failing head.

Both real source-server SQLite probes were repeated and pass on this exact head. After ENOSPC is restored, metadata event 28 persists before held text retries at 29/30 while the prompt stays open. SIGKILL/restart retains the durable prefix and cancels the run; the unpersisted tail is lost. Verifier source is unchanged from the published source; the commands below pass this head as the required pin. Captured server processes have exited and private state has been removed.

The earlier c2eba70 Mac run remains in progress and will keep that attribution. A narrow freshly built 9a3ac59 recording is still required. Boat and GitHub CI are running for the new head. This is not a ready report. Natural Antigravity hangs remain unverified.

Final-head check and review evidence for 9a3ac59da77de24374422a5d834d3bafd891edd5, merge base 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0.

fleet-job check 28221 --head 9a3ac59da77de24374422a5d834d3bafd891edd5 passed on Boat job m5hrhonvsywjmrb2, VM bx_72jc2f6n. Exit 0; 96 tests, formatting, lint, knip, GraphQL and affected-package typechecks pass. The VM was confirmed deleted.

Final-head CI also passes, including the previously failing OpenCode nested-continuation shards. The fresh independent review confirms the ordered pending-work guard fixes the CodeRabbit finding. Reply and resolution.

Main through 5c004fd08bd8c141db994f02a2cdbf04f1a4cc65 adds voice changes and PR-generation instructions/evals. None changes these six files, ingestion, storage, batching or assistant rendering; no additional rebase or verification is warranted for that range. The current-head Mac capture is still pending; this comment does not establish client behavior or readiness. Natural Antigravity hangs remain unverified.

Fresh physical-Mac comparison at baseline 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0 and intermediate head c2eba7006f04559a2c998b307a1e84ae16f080ba. Desktop, server and web were freshly built at both clean commits, version 0.1.7, Electron 44.10.1, macOS 27.0.1 arm64 on shiv. Provider-write batching was enabled. These recordings retain those commits' attribution. The freshly built final-head recording is now published at https://github.com/pingdotgg/t3code/pull/28221#issuecomment-6679620224.

Before: after the prefix and an incomplete trailing paragraph are emitted, the real app shows only the prefix while the original command and turn stay open. Completion finally reveals the tail.

After at c2eba70: the same view and gated free ACP sequence shows the full tail during the original open command and turn. Open-turn reload retains it; completion arrives through the replacement subscription; completed reload retains finalized text.

https://github.com/user-attachments/assets/a66fdea7-801e-4aa2-a2bf-772fe753b86d

Full-turn control at c2eba70: text stays buffered until completion. The final encoded frame shows the full completed text.

https://github.com/user-attachments/assets/d53d4539-a3db-4b44-99af-9aa55b28170e

Stop control at c2eba70: Stop during the pending interval interrupts the original run, finalizes received text, and late release does not reopen streaming or the run.

https://github.com/user-attachments/assets/5a101654-3516-45cb-a475-164a3bd8c2ea

The replay uses the real ACP registry adapter, compiled server, SQLite/event store, RPC subscription and compiled renderer in Electron. It gates provider output and completion; it does not replace the backend. No account or paid provider was used. The parent inspected the encoded frames from all four MP4s, including the terminal full-turn frame. All 224 collected artifact hashes match; initial/final hashes for each build's 4,322 files are identical.

python3 assert-current.py passed 112 assertions covering persisted identities, text, streaming/run states, reload and replacement-subscription delivery. The replacement head subscription resumed at sequence 32 and received 12 Chunk frames, including one synchronization frame and 18 persisted events. All 12 were ACKed. Three head subscriptions had Chunk/ACK counts 11/11, 12/12 and 1/1.

The only production change after c2eba70 is the independently reviewed ordered OpenCode pending-work guard in 9a3ac59. ACP omits that optional flag, so these baseline, full-turn and Stop controls remain applicable. The final-head paragraph/reload/completion capture is published separately at https://github.com/pingdotgg/t3code/pull/28221#issuecomment-6679620224. This comparison retains its c2eba70 attribution.

Unproven: natural Antigravity hangs, real-provider behavior, continuation-enabled crash recovery, separate relay/T3 Connect routes and signed installers. This server-only diff has no platform-specific mobile change; the reported desktop behavior is exercised here. Task-owned apps, processes, builds, worktrees and private profiles were cleaned up and the device lock released.

PR https://github.com/pingdotgg/t3code/pull/28221

Independent evidence review found no findings in the c2eba70 Mac comparison or exact-head 9a3ac59 SQLite/runtime evidence. The reviewer decoded the actual MP4s, inspected fixture and assertion sources, verified all 224 artifact hashes, recomputed build-manifest hashes, and matched source and commit-object hashes to Git. It checked persisted text/run identities and the actual replacement RPC subscription, including the completion received before the final reload. It separately inspected the real ENOSPC cause, metadata-before-retry event order and SIGKILL/restart state.

The controlled fixture uses the real adapter, server, persistence, RPC and compiled client. It does not reproduce a natural Antigravity hang or a real shell background workload. The only c2-to-9a3 production change is the OpenCode pending-work guard; ACP omits that optional flag, so the full-turn and Stop controls transfer. A fresh narrow final-head app supplement is still running and must be reviewed before readiness.

The required route is server tests plus the reported Mac client; there is no platform-specific client code in this diff. Natural Antigravity hangs, real-provider behavior, separate relay/T3 Connect routes, signed installers and continuation-enabled crash recovery remain unverified. Restart evidence explicitly shows that the unpersisted held tail is lost. Automatic repair after every SQLite COMMIT failure is not claimed.

Independent evidence review

Independent evidence review for PR 28221

Current head: 9a3ac59da77de24374422a5d834d3bafd891edd5. Comparison baseline / merge base: 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0. Mac comparison head: c2eba7006f04559a2c998b307a1e84ae16f080ba.

Read-only independent review on 2026-11-06 UTC. I did not implement this change, run product tests, start a server, post, push, or delegate. Only this requested report was written. Artifact decoding, hashing, and data inspection did not modify the supplied evidence. I applied fleet full-send evidence criteria and the repository's review/testing guidance. The separate source review remains in final-review-findings.md.

Result

Clear for the scoped c2 client comparison plus exact-head 9a3 runtime evidence. No new blocker, should, or nit finding. The evidence establishes the behavior it actually exercises. It does not establish whole-PR readiness while the separately running final-head app supplement remains pending.

The existing baseline, full-turn, and Stop controls transfer to 9a3. Repeating those unchanged controls is unnecessary. The final-head app result will need its separate supplement review, as already planned. This known pending item is not a newly discovered gap.

What I inspected directly

All four encoded-frame sheets and the turn terminal frame. I also decoded the actual MP4s independently in memory and viewed frames at baseline 35.33 s, c2 paragraph 35.23 s, turn completion 10.195455 s, and Stop 10.52 s. The actual recordings show the same states as the retained captures. I did not rely only on the report's descriptions or the sheets.
The fixture, launcher, desktop loader, GUI actions, Stop race, capture/completion helpers, SQLite export/collection code, and all 112 fixture assertions. I inspected state snapshots, persisted event sequences, actual renderer socket frames, ACP gate/cancel records, runtime versions, build commands/logs, and source/build provenance.
Both runtime verifier programs and shell wrappers, source manifest, verdicts, milestones, database/API exports, and the SQLite failure log. I read the actual published comments 6678833267, 6678244004, and 6678984841. The published TypeScript verifiers equal the supplied local verifier sources; the published Boat result JSON equals the retained result.
The c2-to-9a3 production delta and the optional pending-work flag's provider scope. Live GitHub state still identifies 9a3 as the head; all five review threads are resolved, CodeRabbit and Macroscope correctness are successful, and the PR is open, non-draft, and mergeable. No Julius-authored commit appears in this PR's current commit list.

Client comparison is valid for its stated scope

The baseline and c2 use the same compiled desktop view and gated ACP scenario, with provider commit batching enabled. Both are app version 0.1.7 on physical shiv, arm64 macOS 27.0.1 build 26A434. The recorded runtime is Electron 44.10.1, Chromium 152.0.7977.169, embedded Node 24.22.1, and SQLite 3.53.4. The captured build-command Node process is 26.12.0. Its distinction from the workspace version report is disclosed in the supplied report.

The baseline held sample has one original running run, a running command item, and prefix-only streaming assistant message/item records. Its video shows only "First paragraph." with Stop available. Full text appears on completion. At c2, the same trigger persists the full tail in the assistant message and item while that original run and command remain running. The actual MP4 shows that tail with Stop still available.

The c2 events independently support this order:

Sequence	Persisted event	State
27 / 28	Assistant message / assistant item	Prefix, streaming true
29 / 30	Assistant message / assistant item	Full text, streaming true
34 / 35	Assistant message / assistant item	Full text, streaming false

The full streaming records were written at 06:39:15.374Z / 06:39:15.377Z. The held sample is at 06:39:17.729Z; completion was gated until 06:40:12.417Z. Completion therefore cannot explain the earlier visible tail. API messages agree with the supplied SQLite message records.

The actual Cmd+R records and three distinct renderer sockets establish two reloads. The replacement subscription requests the same thread after sequence 32. It receives unique ordered events 33 through 50, including finalized assistant records at 34/35 and the original run's completed event at 48. Its 12 Chunk frames have 12 ACKs. The completed renderer capture predates the final reload socket and has full text with Stop absent. Reloaded held/completed samples preserve the original run, assistant message, and assistant item identities. This proves completion arrived over the replacement subscription rather than only through the later reload.

The turn-mode control contains no assistant message/item at either open-turn sample, followed by full nonstreaming text on completion. I viewed its short encoded terminal state directly. This control does not demonstrate idle delivery in turn mode and makes no such claim.

The Stop trace emits its tail at 06:41:27.027Z. The 06:41:27.031Z pending sample remains prefix-only with the original run running; real GUI Stop reaches ACP cancel at 06:41:27.145Z. Full text is finalized rather than discarded, and the run becomes interrupted. The later release leaves the same run interrupted, both assistant records nonstreaming, and no streaming assistant update follows interruption. The MP4 visibly agrees. This proves cancellation with received text held before idle delivery, not a claim that Stop erases received text.

Fixture and provenance

The fixture supplies synthetic ACP messages and a synthetic open command item. It does not run a natural Antigravity workload or a real shell background command. That is appropriate for the claimed controlled text-delivery proof: the real ACP adapter, compiled server, orchestration, event store, SQLite projections, RPC subscription, and compiled desktop renderer perform the behavior under review. No fixture implementation substitutes the paragraph filter, idle timer, event sink, subscription, or renderer. The control gates release provider input/completion; they do not invoke the idle flush themselves.

The desktop loader selects isolated homes, port, profile, and clean compiled boot file; it observes WebSocket traffic. It does not fabricate response text or alter buffering. The app is a task-owned Electron launch of compiled product code, not proof of a signed installer. Client SQLite inspection is read-only, and project/thread creation uses real application APIs. The storage verifier separately uses a real SQLite connection for observation and WAL checkpointing; it does not insert fake projection or event rows.

All 224 entries in the supplied artifact SHA-256 manifest match the retained files. Start and end build-provenance JSON are equal. Each build records 4,322 built files. Both recorded source trees are clean. I independently matched all six changed source-file hashes and both commit-object hashes to the local Git objects, and recomputed the aggregate build-manifest hashes to match build-summary.json. The primary desktop boot/main and web index hashes match between baseline and c2; the server bundle differs, consistent with this server-only diff. Build logs show successful fresh desktop and server/web builds. The builds were cleaned up, so this review validates the retained build/run provenance rather than rerunning those binaries.

Exact-head storage and restart evidence

The runtime manifest's six source hashes match Git head 9a3. Both verifier programs assert that exact clean source head before launching their isolated source servers. They run on physical corex with Node 26.12.1 and file-backed SQLite, using a controlled free ACP provider.

The disk-full wrapper mounts a private 16 MiB tmpfs in a private user/mount namespace. The verifier fills it after checkpointing/truncating WAL, observes ENOSPC from both filler and independent canary writes, and waits for the real idle-flush warning. The server log contains the actual "database or disk is full" cause. The during-failure export retains only the prefix with a running original run. It then removes the filler; the canary succeeds. An ordinary ACP metadata event persists at sequence 28, before the full streaming message/item retries at 29/30. Both retries exist in the exported event log and projections while the same run remains running. Completion is gated on those observations. Thus this proves real disk-full failure and retry after space restoration, with normal provider ingestion before the text retries and no new text or prompt completion required.

The crash verifier captures its spawned server PID, SIGKILLs that server at the prefix-only cutpoint, observes actual SIGKILL exit, and starts a new server against the same isolated home. Before restart, the durable prefix is still streaming and the run is still running. After restart, SQLite and the real read API agree: one original cancelled run, the prefix retained, and both assistant representations nonstreaming; the assistant item is cancelled. The full held tail never enters the durable event log. This proves reconciliation with continueThreadsAfterServerUpdate:false. It does not prove recovery of the unpersisted tail or continuation-enabled side-effect recovery.

The separate COMMIT regression explicitly executes manual ROLLBACK to repair the deferred-constraint failure's still-open SQLite transaction. Its test and the PR's limit disclose this. It establishes preservation/retry across that repaired failure; automatic repair after every possible COMMIT error remains unclaimed. The real ENOSPC run supplies separate production-path storage-recovery evidence without injecting that manual rollback into the server.

Transfer, required clients, and limits

Only six server files differ from the comparison base, including two test files. There is no mobile, web, Electron shell, contract, OS-specific, relay, or tunnel change in this PR. The supplied device route calls for source tests, and the reported Mac desktop app supplies the visible integration proof. No additional phone, Windows, or Linux desktop run is left unproven by this required device list.

Between c2 and 9a3, the only production change retains the last successfully stored root snapshot's optional pendingBackgroundWork flag and consults it when deciding whether ingestion can end. Only the OpenCode adapter emits that flag; ACP omits it, leaving the new guard false. No c2 fixture path, idle deadline, persistence implementation, reload subscription, turn-mode behavior, or Stop implementation changes. Those c2 controls therefore remain valid evidence for their unchanged behavior. The OpenCode change is supported by the separately reviewed nested replay/CI evidence, not by claiming that the ACP recording exercised OpenCode. Main's unrelated voice/PR-prompt movement is covered by the separate source review and is not represented as part of the Mac comparison.

The final-head app supplement remains pending for this review. Natural Antigravity hangs, real-provider behavior, separate relay/T3 Connect routes, signed installers, and continuation-enabled crash recovery remain unverified and must keep that attribution. None is established merely by the synthetic ACP fixture or by a successful source test. The supplied PR text already states these limits.

Checks, redaction, and handback

The retained final Boat result pins head 9a3 and merge base 2e39, reports exit 0, and passes format, lint, knip, GraphQL, affected-package typechecks, and tests. Its actual log reports 96 tests in four files. The published JSON matches it. The other retained focused/replay logs contain the stated 105, 70, and 29-case totals; those logs alone do not independently stamp a source SHA. Commit-keyed final CI and the pinned Boat result supply the stronger current-head check provenance. I ran no tests during this review.

I inspected the recording contents and sanitization paths and independently scanned 244 retained Mac/runtime text artifacts for credential values, bearer tokens, ticket URLs, JWTs, and private keys. No matching secret value was found. Synthetic-only thread payloads, stripped socket query strings, and parameter-free ACP traces agree with the stated collection scope. No redaction or fixture-faking issue was found. This is an inspection of the retained artifacts, not a claim that a pattern scan proves the absence of every possible secret.

No new finding requires a fix. Keep c2 attribution on the comparison, keep the final-head app supplement pending until reviewed, and preserve the stated runtime/provider limits. Readiness belongs to the parent after that supplement and its live ready check.

Provider commit batching was enabled.

The recording starts before output. The gated free ACP provider emits a prefix and then an incomplete trailing paragraph. The real compiled app shows the full tail while the original command and run remain open with Stop available. Cmd+R preserves the held text. Completion then arrives over the replacement RPC subscription without another reload; completed Cmd+R retains the finalized text.

Final-head recording, 49.85 seconds, actual application window:

Final-head held sample, original command and run still open:

The matching baseline and unchanged full-turn/Stop controls are in the fresh comparison. Those controls retain c2eba70 attribution. This final-head capture uses no earlier recording or build artifact.

Independent final evidence review found no client or sanitization finding. All three requested current-main recovery integration cases passed, and a fresh closure review resolved F1 with no new findings: https://github.com/pingdotgg/t3code/pull/28221#issuecomment-6679818041.

61 focused assertions passed. The replacement socket opened at 07:02:18.727Z, completion was released at 07:02:33.754Z, and the final reload socket opened at 07:02:36.796Z. The replacement subscription resumed after sequence 31, received one synchronization value plus 18 persisted events in 12 Chunk frames, and ACKed all 12. The live-completed renderer frame precedes the final reload. Original run, assistant message and turn-item identities persist across both reloads.

This is a real ACP adapter, compiled server, isolated SQLite/event store, RPC and compiled desktop renderer. The fixture gates provider input and completion, with a synthetic open command item. It does not replace the backend or renderer. No accounts, paid providers or personal data were used. The parent inspected all six encoded MP4 milestone frames and verified all 99 retained artifact hashes, unchanged start/end build manifests, and the six source hashes against Git. All 4,322 build-file hashes aggregate to 5e1f85c2b3b63f799bb97d7c661442ab11b83628bf9a6b15dbf4d6c6ac0e87fd.

Natural Antigravity hangs remain unverified. This proves controlled open-prompt text delivery, not the provider's underlying hang. Real-provider behavior, separate relay/T3 Connect routes, signed installers and continuation-enabled crash recovery remain unverified. Server-only source routing adds no phone/simulator requirement. The app, captured processes, build, private profiles, worktree and device lock were cleaned up; both remote task folders were removed after verified collection.
