fix(server): show idle paragraphs before the assistant turn ends - #28221
Paragraph mode can hide the assistant's last paragraph while a tool or background command keeps the provider turn open. Keep the latest held snapshots and deliver them after 800 ms of inactivity, still streaming. Order idle delivery with provider ingestion, preserve run and child ownership, and retry failed writes after storage recovers. Full-turn mode stays buffered.
Refs #28175. The sibling-wakeup fix#28204 is on main. This PR fixes text delivery during an open prompt. Natural Antigravity hangs remain unverified.
Main's provider-write batching required rebuilding the ingestion integration. The timer now queues an idle control item for the existing consumer. It runs outside the shared batch transaction and marks text delivered only after its write commits. consumeProviderEvents accepts these control items without changing provider snapshot batching. Ordered pending-work snapshots also keep read-ahead from ending OpenCode child ingestion before continuation text arrives.
Evidence
Evidence pins source head 9a3ac59da77de24374422a5d834d3bafd891edd5 and original base 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0. Later main changes are reviewed through 2756da402b5d795baa05762cba1706a2c0e2fac8; the related recovery cases pass on the combined tree. The later Intel Mac Antigravity installer and packaged-app architecture-exclusion changes leave streaming, persistence and the recorded ARM64 build path unchanged. Final evidence and base review.
Before, freshly built baseline desktop with the trailing paragraph held while the command and original turn remain open:
before.mp4
After, freshly built current-head desktop with the same trigger, tail visible during that open turn, reload retention, completion on the replacement subscription, and completed reload:
Recordings before c2eba70 retain their original attribution and are superseded for this batching integration.
Limits and risk
The free gated ACP fixture proves idle delivery through the real server and compiled client. Natural Antigravity hangs and real-provider behavior remain unverified, as do separate relay/T3 Connect routes, signed installers, and continuation-enabled crash recovery. Device routing calls for source tests for this server-only diff; the real Mac app supplies the visible proof.
The COMMIT regression models connection repair explicitly; automatic recovery from every COMMIT error is not claimed.
An idle delivery can briefly show unfinished Markdown. Held text is memory-only until it commits. Reverting the change restores previous buffering without a schema migration.
Submitted under CONTRIBUTING.md's focused obvious-bug exception. This restores paragraph-mode delivery without adding a setting, provider capability, contract or separate workflow. No explicit maintainer scope approval is claimed.
Implemented with Claude Opus 5.5 through Claude Code. Investigated, tested and reviewed with GPT-6.1-Sol through the Codex harness in T3 Code.
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>:
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
[GPT-6.1-Sol][Codex] on behalf of shivam.
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 #28204. No merge, auto-merge or approval was performed.

Macroscope's review found this PR approvable — Paragraph streaming now shows held text after 800 ms of inactivity instead of waiting for another provider update. Ordered writes, ownership checks and bounded retries limit the risk; full-turn buffering remains unchanged.

Walkthrough
The assistant streaming filter retains paragraph updates for idle delivery. RunExecutionService serializes idle flushes with provider-event ingestion, retries failed writes, and closes flushing when the run or event stream ends.
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 retains paragraph updates for idle delivery and tracks delivery, retry, and discard outcomes. Tests cover timing, retries, superseded snapshots, rewrites, and turn mode.
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 serializes flushes with provider-event ingestion, retries failed writes, and closes flushing on terminal or stream shutdown. Tests cover root and child delivery, retries, ordering, handoff, and blocked-flush cancellation.

Possibly related issues
pingdotgg/t3code#19228: The PR changes the ingestion stop check to use the stored root pending-work snapshot, which relates to the issue’s concern about lost queued child continuation events. The supplied context does not establish that the PR covers both reproductions.
pingdotgg/t3code#28175: The PR queues idle flushes for held paragraph text while background work continues. The issue also describes a separate delegated-wakeup defect.

- Around line 3894-3897: In the test using paragraphDelivered, add a separate
Deferred that is completed when the streaming turn_item.updated event containing
“First.\n\nWaiting on the build” is ingested. Await it immediately after
TestClock.adjust and before offering later events to providerEvents, ensuring
the idle flush has been delivered before the next snapshot.

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 #28175 (comment)):
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.

ran vp i in separate main and pr checkouts, then each real vp run dev in the background, one server at a time. created a local git project and threads through the web app. used repository playwright, /usr/bin/google-chrome, and real codex gpt-6.1-sol through the local proxy.
a temporary passthrough wrapper paused the real codex process and subsequent stdout forwarding for 8 seconds after a real text delta. it generated no output and altered no bytes. this proves a controlled provider pause, not a naturally occurring antigravity hang.
main hid the held tail during the pause, showing it on message completion.
the pr rendered the tail while its assistant turn item remained streaming: true, status: running.
settings > threads > advanced > response streaming > wait for the full response suppressed partial text during the same pause, then displayed the complete response.
paragraph mode completed with the full text intact. stop after idle delivery left the run interrupted without reopening after forwarding resumed. the paused provider delayed cancellation, and remaining text arrived after the click; this does not prove immediate cancellation or frozen text.

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:
vp i --frozen-lockfile
# From apps/desktop:
node scripts/build-browser-secret.mjs && node scripts/build-preview-annotation-css.mjs && vp pack
# From the checkout root:
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.
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.
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.
Recordings
Baseline, held tail remains hidden until completion:
main-before.mp4
Candidate, prefix at 6 s, tail released at 17 s, full text visible with the command and turn open, completion at 46 s:
Refreshed base-impact verification at head fc00e3681d6f6bbe05061665ea063cf99cfcb945, baseline e68e19d605485db6ef31b2033f67a9d07634fc2b. All nine patches rebased unchanged. Main does not change the four PR files, but its recovery/projection, queued-background handoff, ACP replacement scope, pruned-cursor fallback and Electron update warranted fresh checks. The bug remains on main. No superseding merged fix or Julius takeover was found.

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.
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.
before.mp4
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.
after.mp4
Full-turn control: both chunks remain buffered until completion at 11.449 s.
turn.mp4
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 #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 e68e19d and advertising candidate fc00e36. 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:
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:
git fetch origin main
git bundle verify ../candidate.bundle
../candidate.bundle is okay
git fetch ../candidate.bundle
In both detached worktrees:
vp i --frozen-lockfile
Done in 17.5s using pnpm v12.14.0 [baseline]
Done in 3s using pnpm v12.14.0 [candidate serial completion]
From each apps/desktop:
node scripts/build-browser-secret.mjs && node scripts/build-preview-annotation-css.mjs && vp pack
✔ Build complete in 719ms [baseline]
✔ Build complete in 753ms [candidate]
From each root:
vp run --filter t3 build
[cli] Bundled web app into dist/client
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.
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.
The same chat view, prompt and text were used before and after:
First paragraph.
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.

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.

Current-head server runtime, disk-full/retry, crash recovery and 259 passing tests: #28221 (comment).
Independent fresh Codex evidence review found no findings or unsupported claims within this stated scope. It verified artifact hashes, exact-build provenance, DB/API/event/UI consistency and cleanup. Natural Antigravity hangs and the other named unverified paths remain unproven. Reproducer and assertion sources: #28221 (comment).
Reproducer and assertion sources for the fresh current-head desktop evidence at #28221 (comment). Head fc00e3681d6f6bbe05061665ea063cf99cfcb945, baseline e68e19d605485db6ef31b2033f67a9d07634fc2b. These external helpers set up isolated test state and control the free ACP replay. They do not patch product behavior.

# Build recipe for this run
Task root: `/tmp/fun-runs/r_hrgnoyrcibmmw000`. These operations used an independent shared clone, never the parent's worktree. Logs are in this directory.
```sh
git clone --shared --no-checkout /Users/shivam-mini/Developer/t3code source
git -C source remote set-url origin https://github.com/pingdotgg/t3code.git
git -C source fetch origin main
scp corex:/tmp/t3code-28221/candidate.bundle ./candidate.bundle
git -C source bundle verify ../candidate.bundle
git -C source fetch ../candidate.bundle
git -C source worktree add --detach ../baseline e68e19d605485db6ef31b2033f67a9d07634fc2b
git -C source worktree add --detach ../candidate fc00e3681d6f6bbe05061665ea063cf99cfcb945
For each worktree, vp i --frozen-lockfile, then from apps/desktop:
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.

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.
before.mp4
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.
after.mp4
Full-turn control: both chunks remain buffered until completion at 7.555 s.
turn.mp4
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.

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 #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:
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.
UTC time
Actual observation
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.
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 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: #28221 (comment). 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.

# Fresh macOS build and capture recipe
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.
```sh
git clone --shared --no-checkout /Users/shivam-mini/Developer/t3code source
git -C source remote set-url origin https://github.com/pingdotgg/t3code.git
git -C source fetch origin main
scp corex:/tmp/t3code-28221/candidate.bundle ./candidate.bundle
git -C source bundle verify ../candidate.bundle
git -C source fetch ../candidate.bundle refs/heads/issue-watch/28175:refs/heads/test-candidate
git -C source worktree add --detach ../baseline 90f0158e60b08946bcaae1df07109a893e7c36af
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:
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.
Before, main a09:
before-main.mp4
After, a09 plus exact d069 patch, including open and completed reload:

Full-turn buffering:

Pending-text cooperative UI Stop and late completion:
pending-stop.mp4
Queued fresh session:
fresh-session.mp4
History-heavy stopped reload:

Verification commands and results:
python3 out/assert-evidence.py
PASS: 167 persisted-state,read-API,reload,UI,cancellation and build assertions
python3 out/assert-supplemental.py
PASS: 42 fresh-session,history,control-budget and pending-Stop assertions
python3 out/record-provenance.py
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.
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 #28221 (comment) and its sources in #28221 (comment). 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.
Budget calculation against captured real-server state
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.
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.
desktop-transport.mp4
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.
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.

Reproduction recipe
Helpers were recovered from corex run r_4vyvyte3ggxeq000 and adapted only for this task root, app identity and candidate-only scope. 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.

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.
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.
Paragraph streaming held a turn's latest text back until the next Markdown
boundary or the final update, so a provider that paused mid-turn (a
backgrounded command, a long tool call) left that text hidden while the turn
stayed open.
A held snapshot is now delivered whole after 800 ms of inactivity. The
filter keeps the latest held message.updated and turn_item.updated snapshot
per message. It never shrinks delivered text, but a provider rewrite or
truncation replaces it. Turn mode is unchanged.
The idle timer only wakes ingestion. The flush runs as its own step of the
run's provider event consumer, ordered with routing and snapshots and
outside any batched commit, so it never waits on the shared batch worker
while that worker waits on it. A write has committed before its text counts
as delivered. consumeProviderEvents accepts such non-snapshot control items,
which it already orders outside the shared commit.
The flush rechecks routing, so a child handed to another run has its held
text dropped. Root finalization and the end of ingestion close the timer
before it can reopen settled items. A failed idle write keeps the text held
and retries it with backoff (1s doubling to 30s, warning at most every 10
minutes) while provider ingestion continues; a newer snapshot with an
earlier deadline reschedules the wake.

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.
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.

- Around line 1597-1618: Update the provider-event ingestion flow around
consumeProviderEvents so an idle_flush tick cannot stop ingestion while provider
events are still queued. Coordinate the stop decision in
shouldStopProviderEventIngestion with queued-event delivery, preserving idle
flushing while ensuring nested continuation output is consumed before ingestion
ends.

…pshot settles
The idle-flush merge pulls provider events ahead of the consumer, so OpenCode's live
pending-work probe could report false while a consumed root snapshot still said work
remained, ending ingestion before the middle child's continuation text arrived.
The stop check now trusts the last stored root snapshot's pendingBackgroundWork before
the live probe. Adapters that omit the flag keep the previous behavior.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

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 #28221 (comment).
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.
before.mp4
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.
after.mp4
Full-turn control at c2eba70: text stays buffered until completion. The final encoded frame shows the full completed text.
turn.mp4
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.
stop-race.mp4
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 #28221 (comment). 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.

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.

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.
PR #28221, head 9a3ac59, checks green; all review threads resolved; scoped evidence review clear; final-head app supplement pending.
Fresh final-head client proof at 9a3ac59da77de24374422a5d834d3bafd891edd5, tree 539e6ec748282afc137c7d48dabc371567a8d192. Physical shiv, arm64 macOS 27.0.1 build 26A434. Desktop, server and web 0.1.7 were freshly built from this exact clean commit. Electron 44.10.1, Chromium 152.0.7977.169, embedded Node 24.22.1, SQLite 3.53.4; build/fixture Node 26.12.0. 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:
after.mp4
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: #28221 (comment).
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.

F1 resolved. Fresh independent review accepted the final-head Mac evidence, verified the three recovery executions below, and confirmed evidence transfer through main 291bcc392c421902cb18b2bf39023bdcae6d5cbe. No findings remain.
Final base addendum: the parent inspected the complete later commit c55db3e9c72fdf584f4b54192fb39beb88667b59. It only changes Antigravity installation and its test, adding ad-hoc signing for Intel Macs and recording installed file sizes. It changes no streaming, ingestion, recovery, persistence, subscription or renderer path. The ARM64 Mac build and controlled ACP fixture do not use that Intel-only installation path. No new verification or rebase is needed; natural Antigravity hangs remain unverified.
Wake base addendum: the parent inspected the full later commit 2756da402b5d795baa05762cba1706a2c0e2fac8. It generalizes packaged Mac app exclusions to omit the other architecture’s native prebuilds, with a test. It changes only scripts/build-desktop-artifact.ts and its test. The recorded builds used vp pack and server/web build commands, not dist:desktop:artifact; streaming, persistence, recovery and renderer code are unchanged. Existing head evidence transfers without another test or app build.
Current-main recovery verification for final head 9a3ac59da77de24374422a5d834d3bafd891edd5. The final app evidence review requested three existing recovery cases because main changed shutdown transactions and recovery queries after the head CI started.
All three passed once on isolated integration tree 60dbe4d8b4cf8c9d42844e3bc3959680469c4339, combining that head with main ccde655b8f3d39af08d5b2e6b56773e4db1b2f89, merge base 2e39f1d7dec44c98a4cabdaf99d3d99209f770c0. The merge was conflict-free, with no manual source or test edits. All six PR source blobs equal the head; the two new recovery test files equal pinned main. The resulting tree and source hashes stayed unchanged after execution. The temporary merge was then aborted; the PR branch was not rebased or pushed.
Physical corex, isolated checkout, existing repository SQLite test layers. Commands ran from the repository root in the supported Node 26/vp environment, with no retries or new tests. Exactly one projection case and both shutdown grouping/rollback variants executed; the other cases were filtered out.
vp test run apps/server/src/orchestration-v2/ProjectionRecovery.test.ts -t "bounds streaming recovery reads by candidate runs and preserves message ordering"
vp test run apps/server/src/orchestration-v2/FoundationPersistence.test.ts -t "groups shutdown commits with rollback="
The projection case checks candidate run selection, wrong-thread/settled exclusions, ordering and indexed reads. The shutdown cases execute EventSink and real SQLite across 65 threads and the 32-thread batch boundary, checking durable state, deferred notification, rollback, retry and idempotency. These cover the related base changes; the independently reviewed final-head app and storage recordings retain their exact commit attribution.

Independent read-only review on 2026-11-06 UTC. I read fleet full-send, product decisions and unslop, repository AGENTS.md, all .macroscope review policies, testing guidance and relevant Effect-service guidance. I inspected the complete four base patches, the PR's production delta, nearby recovery/publication/shutdown code, and the final Mac artifacts. No source changes, product tests, servers, delegates, posts or pushes. The only saved output is this report. MP4 decoding used pipes and left no frame files.
Result
The final-head Mac supplement is valid for its stated controlled ACP scenario. No source defect, sanitization defect, or new client-evidence gap found. The previous c2 baseline, turn-mode and Stop controls retain their c2 attribution and transfer reasoning from evidence-review-comparison.md.
One narrow verification item remains before extending the recovery conclusion to integration with current main. It does not invalidate the exact-head Mac, ENOSPC/retry or SIGKILL evidence. A rebase, implementation redo, fresh desktop build, second app pass, phone or simulator is not required by these four base commits.
Findings
F1, blocker: current-main recovery integration is not established by the supplied head-only checks
This blocks an unconditional current-base readiness conclusion, not acceptance of the final-head app supplement. No failing behavior or source defect was found.
Evidence: 1bdb6cf1cfb55bff8d007caf6f5a36a4001a84cc changes shutdown reconciliation from separate thread commits to groups of 32 through EventSink.withProviderBatch. c22251163132534c4f2048ac35bad8caad0708db changes getRuntimeRecoveryProjection from ten collection queries to one UNION ALL query. These are the recovery reader and transaction path used to settle persisted streaming state after process loss. The supplied boat-nested/out/result.json pins 9a3 and merge base 2e39, and its 96-test result does not establish execution of those new cases on a tree containing current main. The final Mac build also pins 9a3. The previous crash run therefore cannot itself be described as exercising the new recovery query.
Minimal remedy: first inspect existing CI provenance. A successful merge-ref job that contains both reviewed commits and runs the cases below is sufficient. If that evidence does not already exist, run these existing cases once on an isolated integration tree containing head 9a3 plus main ccde, recording both parent commits and the resulting tree/commit. Run from the repository root with the repository's installed dependencies and supported Node/vp environment:
vp test run apps/server/src/orchestration-v2/ProjectionRecovery.test.ts -t "bounds streaming recovery reads by candidate runs and preserves message ordering"
vp test run apps/server/src/orchestration-v2/FoundationPersistence.test.ts -t "groups shutdown commits with rollback="
These are one streaming-selection/order case and both shutdown grouping/rollback variants. The first executes the new SQLite statement over live/terminal run cohorts, excludes wrong-thread and settled messages, and checks ordering and indexed access. The second executes real event-sink/projection/outbox persistence across 65 threads, shared sessions, the 32-thread boundary, rollback, deferred cancellation notification, retry and idempotency. Together they cover the changed recovery mechanisms and their use of this PR's EventSink module without duplicating the already reviewed idle-flush tests.
A Linux server-test environment on corex or Boat is sufficient. Use the real SQLite test layers already defined in these files. No provider account, desktop build, new test, UI test, ENOSPC rerun or SIGKILL rerun is needed. Do not run these on the unchanged 9a3 checkout and call that current-main integration. If integration is achieved by rebasing/pushing, the normal required checks must cover that new head; that is an optional implementation choice, not a prerequisite for this remedy.
No should or nit findings.
Why the four base changes have this impact
Main commit
Inspected interaction
Consequence
e21347b47081d36c2b184fba2685d83300321af9
Adds spans around existing app shutdown, backend scope close/wait, process exit/output drain and history shutdown. The changed test proves concurrent stops and history/markComplete ordering, including a stop defect. Production combinator order and shutdown behavior remain intact.
No new proof needed for paragraph delivery, persistence or crash handling.
1bdb6cf1cfb55bff8d007caf6f5a36a4001a84cc
Reconciliation groups only shutdown with more than one candidate thread. Reads and decisions occur inside the writer transaction. Eventless cancellation signals move after durable group commit. commitCommand publications already defer through CurrentProviderBatch. The PR changes EventSink's consumeProviderEvents type and ProviderCommitBatch's accepted item type; it does not change withProviderBatch, commitThenPublishNow or commitCommand.
Compatible by source review, but genuinely related to recovery and deserving the focused integrated grouping/rollback check in F1. Startup remains ungrouped.
c22251163132534c4f2048ac35bad8caad0708db
Preserves all ten collection predicates, original per-collection ordering and decoders. The message query's run alias changes to message_run without changing its run/thread/streaming filters. Ordered subqueries receive row positions, are combined, then split by section before the same decoders run. No schema or stored payload changes.
Does not affect the idle timer, retry, ordinary live projection reads or subscriptions. It does execute on startup recovery, so F1 checks the new statement rather than pretending the old crash run used it.
ccde655b8f3d39af08d5b2e6b56773e4db1b2f89
Lowers window minimum to 400x360; changes modal/titlebar and settings layout; adjusts draft hero layout; wraps the existing composer shell and moves draft banners outside it. I compared the complete ChatView reindent/reparent patch: model, phase, canInterrupt and send/interrupt callbacks stay the same. Timeline message rendering, RPC subscriptions, reload and server persistence do not change.
No new integrated app build or small-window test is needed for this server PR. The 1100x780 final recording remains proof of the affected view. Base-owned responsive behavior is not an added requirement for this fix.
Shutdown ordering also remains relevant: serverRuntimeStartup.ts interrupts the effect worker, prepares continuation state, shuts down provider sessions, then calls reconcile("shutdown"). RunExecutionService closes its idle wake on ingestion exit. The new recovery batching does not add another live idle-flush consumer or run the timer in the recovery transaction. The PR's ordered root pending-work guard remains confined to provider ingestion. Nothing in these commits changes its OpenCode input or barrier order.
I independently decoded and viewed the actual after/after.mp4 at 1, 4.5, 12.5, 25, 35, 44.5 and 48.8 seconds. These were fresh decodes from the encoded MP4, not reads of the producer's PNGs. They show the synthetic trigger before output, prefix alone, full held text with the controlled command running and Stop available, retained text after the open-run reload, completion before the final reload, and retained completed text after that reload. The frames show the isolated product app and synthetic data. I also decoded the complete video to a null output successfully. Its H.264 stream is 1100x780, about 49.85 seconds, with no audio. Recorder metadata identifies window 22536 and 1,429 captured frames with zero drops; the exported transcode decoded 1,427 frames. I do not conflate the capture and export frame totals.
The fixture emits ACP session updates and gates prefix, tail and completion. It uses the real ACP registry adapter, compiled server, orchestrator/event sink, SQLite, read API, WebSocket RPC and compiled renderer inside Electron. The active command is synthetic provider protocol data, not a real long-running shell command. No fixture replaces buffering, persistence, subscription or UI behavior. State inspection opens SQLite read-only, while project/thread creation and launch use real app APIs. The desktop loader sets isolated paths/ports and attaches a passive sanitized socket observer before requiring the compiled boot file. It does not rewrite the displayed response or the RPC stream.
I read all 61 assertion definitions and their retained results, the fixture/launcher/GUI actions, capture/reload/completion helpers, state export, collection and video-processing code. All 61 recorded assertions pass. I did not rerun them. Raw state and event inspection independently supports their important conclusions:
Milestone
Sample time, UTC
State
Prefix
07:01:56.075
One original running run, prefix-only streaming message/item, controlled command running.
Held
07:01:59.932
Same run, full text streaming, controlled command still running.
Reloaded held
07:02:22.319
Same run/message/item identities and full text, still running.
Completed
07:02:36.087
Original run completed, full message/item nonstreaming, command completed.
Reloaded completed
07:02:39.269
Same completed identities and text.
The thread is 15e00e86-e88d-45e6-a21f-de40379b6d6d, run run:thread:15e00e86-e88d-45e6-a21f-de40379b6d6d:ordinal:1. SQLite message exports equal the API projection at every inspected milestone. The 48 persisted thread events include prefix message/item at 27/28, full streaming text at 30/31, and final nonstreaming text at 34/35. Tail release is 07:01:56.627; full text persists at 07:01:57.486/.488, well before completion release at 07:02:33.754. Completion cannot explain the earlier tail.
I recomputed counts from raw rpc-socket.ndjson, rather than accepting counts.json alone. It has 63 request observations, 150 sent and 118 received frame observations. Thread-filtered traffic has three subscription requests, 26 sent frames, 23 received frames, 23 Chunks and 23 ACKs. Chunk/ACK counts by socket are 10/10, 12/12 and 1/1. These counts exclude fixture setup/control HTTP traffic and the fixture's separate launch RPC.
The original renderer subscription is sent at 07:01:43.215 after sequence 15. The replacement socket opens at 07:02:18.727 and actually subscribes at 07:02:18.777 after sequence 31. It receives one synchronized value and ordered unique persisted events 32 through 49 in 12 Chunks, each ACKed for that subscription request. Event 32 is a visit before completion release; the claim is 18 replacement-subscription events, not 18 completion events. Message/item finalization arrives at 07:02:33.786/.790, and the original run's completed update at sequence 47 arrives at 07:02:33.893. The final reload navigation starts at 07:02:36.680, its socket opens at .796 and subscribes at .880 after sequence 49. Thus both the raw transport and the video show live completion before that reload.
Wire payloads are not byte-for-byte stored payloads. The opted-in deduplication replaces assistant item text with textOmitted:true at 28/31/35, after the matching message text at 27/30/34. Existing packages/shared/src/orchestrationV2DedupedBodies.ts restores that body by messageId. Wire defaults also add empty optional collections/null goal. These differences explain the comparison and are not missing persisted text or backend stubbing.
Provenance and sanitization
All 99 artifact SHA-256 manifest entries match the retained files. Start/end build-provenance JSON are equal. I matched the commit-object digest and tree ID to local Git, all six changed-source hashes to git show 9a3:<path>, and lockfile/root/server/desktop/web package hashes to that commit. Git status is clean here and in the exported build provenance. The 4,322 compiled-file entries aggregate to 5e1f85c2b3b63f799bb97d7c661442ab11b83628bf9a6b15dbf4d6c6ac0e87fd, matching build-summary.json; its primary boot/main/server/web hashes match the manifest. The equal runtime manifests cover 266 runtime files.
Build commands/logs show fresh frozen-lockfile installation, desktop generation/pack, server/web build with remote cache disabled, and runtime setup. Desktop reports successful build; server/web reports 2/2 successful. The loader selects that compiled boot file. The built directories and copied runtime have been cleaned up, so this review validates retained source/build/run provenance, not an independent reopening of the removed binaries.
The physical host is shiv, arm64 macOS 27.0.1 build 26A434. Desktop/server/web versions are 0.1.7. Observed runtime is Electron 44.10.1, Chromium 152.0.7977.169, embedded Node 24.22.1 and SQLite 3.53.4. Fixture/build-command Node is 26.12.0. The global vp report and workspace tool/engine reports describe different launch contexts; the report correctly distinguishes the observed fixture Node from the workspace engine label. Provider commit batching is explicitly true.
The observer strips socket URL queries, keeps only synthetic thread subscription payloads, and records unrelated traffic as tags/sizes. ACP transcript rows whitelist methods, IDs, synthetic session IDs and gate metadata rather than raw parameters. I inspected these paths and independently scanned 86 retained text artifacts for credential values, bearer tokens, ticket/token assignments, JWTs and private-key headers, with no matches. Decoded frames show synthetic-only app data. This is a bounded inspection, not a universal secret-absence guarantee.
Cleanup records show the captured app/server/provider/fixture PIDs already stopped, detached build checkout removed and device/session lock released. I started no app or server and created no temporary decoded frames. Existing supplied evidence remains for the parent to publish/collect; I did not delete it.
Attribution, limits and handback
The earlier published comparison comment #28221 (comment) and review 6679349645 remain c2 evidence, not this 9a3 recording. Existing exact-head runtime evidence in comment 6678833267 and Boat evidence in 6678984841 are not re-audited here. I checked the retained final Boat result's 9a3 provenance to distinguish it from the older c2 Boat folder. Existing head evidence survives the base movement; only F1's current-main recovery combination remains to establish.
Natural Antigravity hangs remain unverified. The free ACP recording does not exercise OpenCode's optional pending-work hook; recorded replay/CI supplies that separate coverage. Real providers, relay/T3 Connect, signed installer distribution and continuation-enabled restart remain outside the demonstrated claims. No phone/simulator is required by this six-server-file diff or the reported Mac app issue. Source-only shared behavior does not create an extra platform-specific client requirement.
I did not refresh live PR state, checks, review threads, takeover status or mergeability. The parent supplied that all five review threads are resolved and final-head checks pass; cached earlier review wording about an unresolved thread is not a current live finding. The parent must complete F1 or locate sufficient integrated CI, then perform the live head/base/check/review/mergeability check. This report does not declare the live PR ready.
PR #28221, head 9a3ac59, checks and reviews: supplied head checks pass and five threads resolved, not live-refreshed here; final app evidence clear, F1 current-main recovery verification pending.
Independent round-two read-only review, 2026-11-06 UTC, by GPT-6.1 Sol through Codex. Reviewed head 9a3ac59da77de24374422a5d834d3bafd891edd5 and the new base range ccde655b8f3d39af08d5b2e6b56773e4db1b2f89..291bcc392c421902cb18b2bf39023bdcae6d5cbe. I read F1 in final-evidence-base-review.md, the retained integration evidence, the full three new base patches, and nearby settlement, terminal, ingestion, finalization and cancellation code. I used repository testing/review guidance, fleet product decisions and unslop. No source edits, tests, servers, apps, delegates, GitHub posts or pushes. This report is the only output I wrote.
Conclusion and ready condition
F1 resolved. No new findings. The supplied executions satisfy F1's requested current-main recovery integration at main ccde655b8f3d39af08d5b2e6b56773e4db1b2f89. The three subsequent base commits do not change the mechanisms exercised by those cases or this PR's behavior. Source review supports transferring that recovery evidence and the previously accepted head evidence through base 291bcc392c421902cb18b2bf39023bdcae6d5cbe.
No additional test, rebase, push, desktop rebuild, app pass, phone or simulator is required by this review. This is a scoped review clearance, not a fresh live-PR readiness assertion. The parent can report ready if its live check still confirms this head and reviewed base, required checks passing or legitimately skipped, resolved findings, an open non-draft conflict-free PR, and no auto-merge or queue that would merge it without Shivam's yes. Reassess any later head/base movement for what it touches.
F1 execution and provenance
The integration evidence is in /tmp/test-pr/t3code-28221/integration-recovery/.

Tested tree 60dbe4d8b4cf8c9d42844e3bc3959680469c4339. Its complete 31,741-entry Git tree equals pinned main with exactly the six PR-file blobs replaced by their exact head blobs. This independently supports the conflict-free merge record and absence of manual source or test edits.
I recomputed all 44 SHA-256 manifest entries. All match. I compared all 15 retained source/configuration files to their Git tree bytes, recorded blob IDs and SHA-256 values, and the post-test source hashes. All match. The six PR files equal head; both requested test files and all seven supporting files equal pinned main.
The saved binary integration patch exactly equals Git's head-to-tested-tree diff. The saved index has stage zero throughout and exactly matches every mode, blob and path in the tested Git tree. The lockfile SHA-256 matches Git, 79fe66979a951086b9c19cb1ad0eeedff7b9b16dc826fcee1b2f2f31dd677f0e.
Before/merge/post records place the merge before both test invocations and preserve the same HEAD, MERGE_HEAD and tree afterward, with empty unstaged diff and untracked-file list. Install, merge, both tests and abort report exit zero. Cleanup records restore clean head tree 539e6ec748282afc137c7d48dabc371567a8d192; my read-only probe confirms the prepared worktree remains clean at 9a3. The parent retains responsibility for that worktree's eventual removal.
I read the actual stdout, stderr and invocation records, rather than relying on result.md alone:

Both logs identify Vitest 5.0.5 and /home/shivam/Developer/.state/t3-auto/worktrees/t3code/t3-d2008cba. Stderr contains the Vite+ built-in-command notice, with no test failure. Each invocation records attempt one and only TMPDIR as an environment override. The retained configuration has retry: 0. The reporter prints counts, not passing-case names. Source contains exactly one matching projection declaration and one matching it.effect.each([false, true]) declaration for the two shutdown variants. Those filters and counts establish the requested three cases, with no missing variant. The retained records show one execution of each command; this review did not rerun them.
The environment was physical corex, Linux x86_64. Root probes report Node 26.12.1, global vp 0.3.2, workspace vite-plus 1.4.0 and SQLite 3.54.0. A separate server-directory probe reports Node 26.13.0. Both invocations ran from the root. There is no in-test Node probe, so I do not assign an independently observed exact Node patch version to the test worker. Both recorded contexts are Node 26, and this distinction is not an F1 gap.
The cases exercise the required layers
ProjectionRecovery.test.ts supplies SqlitePersistence.layerMemory to the real ProjectionStore and EffectOutbox. That layer runs the repository database setup and migrations over NodeSqliteClient.layer({ filename: ":memory:" }); the client uses node:sqlite DatabaseSync. The matching case creates live and terminal run cohorts, settled and wrong-thread messages, foreign-run and old-history rows. It checks the selected message IDs and order, empty results, and EXPLAIN plans for both observed recovery statements. The saved source includes main's UNION ALL recovery query. This exercises the new SQL rather than substituting a fake recovery result.
FoundationPersistence.test.ts composes the real SQLite layer, EventStore, ProjectionStore, EventSink, EffectOutbox and CommandReceiptStore. Both requested variants create 65 threads, cross the 32-thread grouping boundary, share a provider session, count real COMMIT spans, inspect persisted receipts and outbox cancellation status, and assert cancellation notification occurs outside the transaction. The failure variant injects the existing thread-33 defect through a delegating EventSink wrapper and checks that only the first group committed. Both then reconcile again and check idempotency. The EffectWorker is deliberately inert in these existing cases; SQL, recovery decisions, EventSink transactions and persistence remain real. This is the layer combination F1 requested, not an end-to-end provider or crash rerun.

Adds optional stopOnSettle project-action and terminal-launch data, passes it through web/mobile/setup launch paths, and stores it on TerminalManager sessions. Defaults remain false when absent. ThreadSettlementService replaces its post-settlement closeIdle call with closeOnSettle, which closes flagged terminal sessions through the existing closeSession path and then closes idle terminals.
No change to recovery selection, shutdown grouping, EventSink, assistant buffering, provider finalization or provider cancellation. Detailed interaction below supports transferring both recovery and head/runtime evidence without a new command.

Disables Koffi's install-time source-build script in pnpm allowBuilds. It changes no lockfile, package version, production source or runtime selection.
It does not invalidate an already executed native Mac build or SQLite tests. Cross-packaging verification belongs to that base change; this PR does not alter packaging or Koffi. No rebuild required here.
The settlement change is downstream of an actual thread.settled event and rechecks settledOverride before terminal cleanup. Its automatic eligibility checks still reject active runs and pending background work. Orchestrator's manual settlement guard still rejects preparing, starting, running or waiting runs; automatic settlement still dispatches through that mutation path and its live-state checks. An idle assistant flush writes provider message/item snapshots and does not create thread.settled, enable a project-action flag, or invoke terminal cleanup.
Provider finalization and continuing background ingestion remain in RunExecutionService. Its root/child/pending-work guards, ordered root snapshot check, idle wake closure on ingestion exit, and run-current/owner checks are unchanged. closeOnSettle selects TerminalManager's own flagged sessions by thread and invokes the existing terminal process/history close path. It does not call a provider interrupt, terminate a provider session, cancel the ingestion fiber or modify orchestration outbox cancellation. A provider's tool command is not turned into a managed project-action terminal by this patch. The controlled ACP command in the accepted app evidence therefore is not a newly eligible stopOnSettle terminal.
I also compared the range for all 15 retained PR/recovery/test/configuration files, package manifests, lockfile, Orchestrator, EffectWorker, EffectOutbox, EventStore and the shared pending-background-work helper. None changes. The terminal-specific test updates in main exercise its own new behavior; they do not change the three F1 cases. The recovery runs remain executions on 9a3 plus ccde, with source-based transfer to 291bcc, not a claim that the tests ran on 291bcc.
The previously accepted 9a3 Mac 61-assertion supplement at #28221 (comment), c2 baseline/Stop/turn-mode controls at #28221 (comment), exact-head runtime evidence at #28221 (comment) and Boat evidence at #28221 (comment) keep their original commit/build attribution. This review does not re-audit those unchanged artifacts or relabel c2 evidence as 9a3. Nothing in the three new patches invalidates their previously reviewed transfer reasoning.
Limits and handback
Natural Antigravity hangs remain explicitly unverified. The recovery tests do not establish real-provider behavior, an additional app run, relay/T3 Connect behavior, signed installer distribution or continuation-enabled restart. Existing evidence keeps its existing limits. This six-server-file change and the new base range create no additional phone requirement.
I did not refresh live GitHub state, takeover status, checks, review threads, mergeability, auto-merge or queue state. The parent's supplied passing/skipped checks and clear reviews are context, not independent live observations by this reviewer. With F1 closed and no new findings, only the parent's final live readiness check remains within the described work.
PR #28221, head 9a3ac59, checks and reviews: scoped read-only review clear; F1 resolved and evidence transfer through base 291bcc3 clear; live PR readiness remains the parent's responsibility.

Paragraph mode can hide the assistant's last paragraph while a tool or background command keeps the provider turn open. Keep the latest held snapshots and deliver them after 800 ms of inactivity, still streaming. Order idle delivery with provider ingestion, preserve run and child ownership, and retry failed writes after storage recovers. Full-turn mode stays buffered.
Refs #28175. The sibling-wakeup fix #28204 is on main. This PR fixes text delivery during an open prompt. Natural Antigravity hangs remain unverified.
Main's provider-write batching required rebuilding the ingestion integration. The timer now queues an idle control item for the existing consumer. It runs outside the shared batch transaction and marks text delivered only after its write commits.
consumeProviderEventsaccepts these control items without changing provider snapshot batching. Ordered pending-work snapshots also keep read-ahead from ending OpenCode child ingestion before continuation text arrives.Evidence

Later main changes are reviewed through2756da402b5d795baa05762cba1706a2c0e2fac8; the related recovery cases pass on the combined tree. The later Intel Mac Antigravity installer and packaged-app architecture-exclusion changes leave streaming, persistence and the recorded ARM64 build path unchanged. Final evidence and base review.Before, freshly built baseline desktop with the trailing paragraph held while the command and original turn remain open:

After, freshly built current-head desktop with the same trigger, tail visible during that open turn, reload retention, completion on the replacement subscription, and completed reload:

Recordings before c2eba70 retain their original attribution and are superseded for this batching integration.
Limits and risk
The free gated ACP fixture proves idle delivery through the real server and compiled client. Natural Antigravity hangs and real-provider behavior remain unverified, as do separate relay/T3 Connect routes, signed installers, and continuation-enabled crash recovery. Device routing calls for source tests for this server-only diff; the real Mac app supplies the visible proof.
The COMMIT regression models connection repair explicitly; automatic recovery from every COMMIT error is not claimed.
An idle delivery can briefly show unfinished Markdown. Held text is memory-only until it commits. Reverting the change restores previous buffering without a schema migration.
Submitted under CONTRIBUTING.md's focused obvious-bug exception. This restores paragraph-mode delivery without adding a setting, provider capability, contract or separate workflow. No explicit maintainer scope approval is claimed.
