# Final-head evidence transcript for [#23840](https://git.cafe/pingdotgg/t3code/pulls/23840) Head: `1fba4795e3342b9a4db956f25391bde81e0b0fab`. Merge-base: `ef92441313da327139df75daa8f723c0f42348f6`. OS: `Linux fs-36 6.1.102 #1 SMP PREEMPT_DYNAMIC Wed Aug 26 20:12:24 UTC 2026 x86_64 x86_64 x86_64 GNU/Linux`. CLI: `codex-cli 0.163.0`. Provider `codex`, model `gpt-6.1-sol`, reasoningEffort `low`; native turn/start effort `low`, serviceTier absent, approvalPolicy `never`, sandboxPolicy `dangerFullAccess`. Fresh isolated T3 homes: `/tmp/ev-23840/head-home` and `/tmp/ev-23840/before-home`. Seeding disabled with `T3CODE_DEV_SEED=0`. No real T3 data was read, copied, or seeded. Real server, real Codex CLI and authenticated WebSocket RPC; no replay in these runtime sections. No browser was needed. Before used the same installed worktree with the two changed files temporarily restored from merge-base; final-head regression tests were then overlaid unchanged. The production tree matched merge-base exactly; only the final regression test differed (see before-tree-diff.txt). HEAD remained the final commit throughout. The source was restored byte-for-byte afterward; git status was empty. The principal commands used the identical case.mjs, rpc.mjs, and late.prompt bytes. EV_RUN selects only isolated auth/log paths. Driver hashes: ``` 47c495a3a42d142507efa68eb3586f7c385017fccd02c0d594708a864e5898d6 /tmp/ev-23840/rpc.mjs 45edd7f07b19ab6e5cce63c94bccc3a0973488d344c939d0a43a18fc75feb975 /tmp/ev-23840/case.mjs 0048914c37d4e5858ccc63ed5e314f833716d3c09ecf01f354725cb81c240272 /tmp/ev-23840/late.prompt 5200af8a34308e10affdc441ce315e0ed6f590f740efdbc3eb3888a280c8e42e /tmp/ev-23840/head-CodexAdapterV2.ts fbbd557f806a4b8d5a52079b96158ec50c18d729db94fe6ea729a4a5e77349f1 /tmp/ev-23840/head-CodexAdapterV2.test.ts 62a5c88dfd25a68c28f262c879ce40cbc977bc7ebce2ab212a73b65969f9644d /tmp/ev-23840/codex-gate af55f2fdd56bb4e9148b7465e1dd1463d7dece9f31276616788f4135374b65bf /tmp/ev-23840/gated-cancellation.mjs 1f54cb8a7a7f62bf7443c25275d153ddf8076f57568005645d6ef479d33037a7 /tmp/ev-23840/cancelgate.prompt ``` ## Exact red / green Command from apps/server on both sides: ``` vp test run src/orchestration-v2/Adapters/CodexAdapterV2.test.ts src/orchestration-v2/ProviderContinuationService.test.ts src/orchestration-v2/ProviderRuntimeRecoveryService.test.ts ``` Final head: exit 0, 104 passed in 3 files. Merge-base production with final regression driver: exit 1, 4 failed / 100 passed; two failures are explicit expected-1/actual-0 assertions and two are waits for missing continuations that reach the existing 120-second test timeout. These timeouts are red-side missing-event failures, not passing no-wake evidence. Original merge-base tests: exit 0, 100 passed. Exact unedited outputs are in tests.txt. ## Principal ordering and control Head: root completed `21:38:30.258Z` < native child completed `21:39:15.000Z` < automatic root run 2 started `21:39:15.928Z`. One external user input, one durable agent/server-origin completion input, two completed root runs. No parent wait tool or follow-up user input. Child shell sleep deliberately makes completion late; it does not resume the parent. Before: root completed `21:48:03.712Z` < child completed `21:48:43.000Z`; root stayed at one completed run. A distinct observation thread started at `21:48:49.153Z` and completed `21:48:51.720Z`, proving provider processing advanced beyond the child terminal event. Final read-only observation at `21:48:56.300529Z` had no pending/running effects and no automatic input/run on the principal thread. No manual recovery input was sent. ## Runtime cases ### HEAD: late Provider/root/native-child IDs and parent relationships: ```json { "providerThreads": [ { "id": "provider-thread:provider:codex:native-thread:pending%3Arun%3Athread%3Aev23840-late%3Aordinal%3A1", "appThreadId": "ev23840-late", "nativeThreadRef": { "driver": "codex", "nativeId": "01a1658d-0b03-77d2-8386-9be6377a9670", "strength": "strong" }, "status": "idle" }, { "id": "provider-thread:provider:codex:native-thread:01a1658d-1858-7a20-91df-4a8b27a01528", "appThreadId": "thread:provider:codex:native-thread:01a1658d-1858-7a20-91df-4a8b27a01528", "nativeThreadRef": { "driver": "codex", "nativeId": "01a1658d-1858-7a20-91df-4a8b27a01528", "strength": "strong" }, "status": "idle" } ], "children": [ { "id": "node:provider:codex:native-item:call_e867b393438a48a4b0d20a561ce9cab3%3A01a1658d-1858-7a20-91df-4a8b27a01528", "threadId": "ev23840-late", "runId": "run:thread:ev23840-late:ordinal:1", "parentNodeId": "node:run:run%3Athread%3Aev23840-late%3Aordinal%3A1:root", "origin": "provider_native", "createdBy": "agent", "driver": "codex", "providerInstanceId": "codex", "providerThreadId": "provider-thread:provider:codex:native-thread:01a1658d-1858-7a20-91df-4a8b27a01528", "childThreadId": "thread:provider:codex:native-thread:01a1658d-1858-7a20-91df-4a8b27a01528", "nativeTaskRef": { "driver": "codex", "nativeId": "call_e867b393438a48a4b0d20a561ce9cab3:01a1658d-1858-7a20-91df-4a8b27a01528", "strength": "strong" }, "prompt": "", "title": "/root/ev23840_late", "model": "gpt-6.1-sol", "modelSelection": { "instanceId": "codex", "model": "gpt-6.1-sol", "options": [ { "id": "reasoningEffort", "value": "low" } ] }, "status": "completed", "result": "EV23840_LATE_CHILD_DONE", "startedAt": "2026-10-22T21:38:28.000Z", "completedAt": "2026-10-22T21:39:15.000Z", "updatedAt": "2026-10-22T21:39:15.874Z" } ] } ``` Persisted root runs: ```json [ { "id": "run:thread:ev23840-late:ordinal:1", "threadId": "ev23840-late", "ordinal": 1, "providerInstanceId": "codex", "modelSelection": { "instanceId": "codex", "model": "gpt-6.1-sol", "options": [ { "id": "reasoningEffort", "value": "low" } ] }, "providerThreadId": "provider-thread:provider:codex:native-thread:pending%3Arun%3Athread%3Aev23840-late%3Aordinal%3A1", "userMessageId": "9323ba62-65e5-45e6-993d-6c9b2c23de61", "rootNodeId": "node:run:run%3Athread%3Aev23840-late%3Aordinal%3A1:root", "activeAttemptId": "run-attempt:run:run%3Athread%3Aev23840-late%3Aordinal%3A1:attempt:1", "status": "completed", "queuePosition": null, "requestedAt": "2026-10-22T21:38:24.244Z", "startedAt": "2026-10-22T21:38:24.723Z", "completedAt": "2026-10-22T21:38:30.258Z", "checkpointId": "checkpoint:scope:checkpoint-scope%3Athread%3Aev23840-late%3Aname%3Aroot:name:1", "contextHandoffId": null }, { "id": "run:thread:ev23840-late:ordinal:2", "threadId": "ev23840-late", "ordinal": 2, "providerInstanceId": "codex", "modelSelection": { "instanceId": "codex", "model": "gpt-6.1-sol", "options": [ { "id": "reasoningEffort", "value": "low" } ] }, "providerThreadId": "provider-thread:provider:codex:native-thread:pending%3Arun%3Athread%3Aev23840-late%3Aordinal%3A1", "userMessageId": "message:thread:ev23840-late:ordinal:1:4a470504-3413-4edc-9e1b-ffa73be4bc2d", "rootNodeId": "node:run:run%3Athread%3Aev23840-late%3Aordinal%3A2:root", "activeAttemptId": "run-attempt:run:run%3Athread%3Aev23840-late%3Aordinal%3A2:attempt:1", "status": "completed", "queuePosition": null, "requestedAt": "2026-10-22T21:39:15.882Z", "startedAt": "2026-10-22T21:39:15.928Z", "completedAt": "2026-10-22T21:39:18.209Z", "checkpointId": "checkpoint:scope:checkpoint-scope%3Athread%3Aev23840-late%3Aname%3Aroot:name:2", "contextHandoffId": null, "workStartedAt": "2026-10-22T21:38:24.723Z" } ] ``` Persisted conversation (exact text and origin): ```json [ { "createdBy": "user", "creationSource": "web", "id": "9323ba62-65e5-45e6-993d-6c9b2c23de61", "threadId": "ev23840-late", "runId": "run:thread:ev23840-late:ordinal:1", "nodeId": "node:run:run%3Athread%3Aev23840-late%3Aordinal%3A1:root", "role": "user", "text": "Evidence case EV23840_LATE.

Snapshot 1 at `21:39:39.730053Z` shows direct child still running and root still at run 1, after the separately delivered resume-case continuation run 2 completed at `21:39:26.696Z`. The stronger FIFO processing boundary is resume run 3: its completion input was requested at `21:39:54.849Z`, after grandchild completion, and its run completed at `21:39:56.864Z` while the direct child remained running until `21:40:09Z`. Persisted nested root history contains no second run until the direct-child input at `21:40:09Z`. Exactly one direct-child root continuation then completed at `21:40:11.737Z`. Grandchild result never became a root continuation message. - Original active root: child completed at `21:39:15.963Z` inside root run 1 (ends `21:39:51.125Z`). Final root answer contains EV23840_FOREGROUND_CHILD_DONE. No server-origin input or extra root run, including after the global processing boundary. - Later active root: old child completed at `21:40:22Z` during root run 2 (`21:39:11.034Z`–`21:40:56.783Z`). Root 2 answer contains EV23840_LATER_CHILD_DONE. Exactly two external user inputs/two root runs, no server-created completion input or queued redundant run. - Interrupted parent: explicit run.interrupt accepted sequence 295. The real CLI emitted interrupted terminal events for root and child; child final status remained interrupted. Snapshot 1, before recovery input, still shows only the interrupted root run and no wake, after another eligible continuation had been delivered. The explicit fresh user recovery turn subsequently returned EV23840_RECOVERY_OK. This is real cancellation/terminal suppression; the additional GATED HEAD fixture below delivers an unchanged real successful child completion after persisted parent interruption; the ordinary cancellation fixture alone does not claim that ordering. - Interrupted direct child with settled root: root ended `21:43:39.290Z`; a native grandchild interrupted its direct parent at `21:44:04.589Z` and completed EV23840_CANCEL_SENT at `21:44:06Z`. Root stayed at one completed run with no completion input. This independently covers interrupted-child exclusion while no root turn is active. - Global post-processing boundary: a new eligible barrier child completed after every suppression case. Its server-created message caused barrier run 2 (`21:45:00.678Z`–`21:45:02.663Z`). The shared continuation worker takes and dispatches requests sequentially from a FIFO queue (ProviderContinuationRequests.layer and ProviderContinuationService.layer); delivery of this later request is an observable boundary after any earlier eligible offers. Final snapshot at `21:45:43.834928Z` has all children terminal, no pending/running effects and the same expected run counts: late 2, foreground 1, later 2, nested 2, resume 3, interrupted 2 including the explicit recovery, childinterrupt 1, barrier 2. There are no duplicate server completion inputs or root runs after delivery and settling. This is bounded evidence through shutdown, not a claim about arbitrarily delayed future activity. - Snapshot 1 initially queried the retired, empty orchestration_v2_events table for a sequence high-water mark, so its sequence is null. Its live projection records are valid. Later snapshots/export correctly use orchestration_events. All observation assertions use persisted terminal milestones and later delivered work, not elapsed sleep or an early run-count sample. ## Failure coverage classification No genuine native provider failed-turn condition was induced. A nonzero shell exit would not establish a failed provider turn. Per the pass-1 audit exception, failed-child wake coverage is **focused-replay-only**: an external /tmp copy of the final late-child regression drives a failed child turn after completed root and asserts exactly one message_text offer labeled Subagent failed with its partial detail preserved. make-focused.py is the exact transformation; no repository source/test was changed for this supplemental proof. The replay does not prove a real failed child was consumed by Codex. Existing scoped tests cover failed/interrupted provider lifecycle and a child completed-race after Stop; real cancellation and fresh recovery are shown above. ## Exploratory attempts (excluded from required proof) subagent.stop on a completed root was rejected: The requested native subagent cannot be stopped on this run. Native self-interrupt was rejected: an agent cannot interrupt itself; return your result and let the parent interrupt you if needed. Those children completed normally and each woke its root once. The successful interruption fixture instead used a native grandchild to interrupt its direct parent. Exploratory runs remain explicitly visible in runtime-head.json and were all terminal before the final boundary. ## Controlled real-CLI completion delivery after interruption A fresh isolated `/tmp/ev-23840/gate2-home` server ran the same final head and real Codex binary through the external `codex-gate` stdio driver. Native child ID `01a1659e-aa96-7131-a62d-771df216fc20` actually completed at `21:57:54Z`, while root remained active. The driver held its real turn/completed and parent subAgentActivity completion frames, without changing bytes. This deliberately delays delivery, not the underlying work. It is disclosed transport control, not replay or a claim of a naturally occurring race. The explicit run.interrupt receipt committed sequence 51 at `21:58:16.620Z`. Root run 1 persisted interrupted at `21:58:16.662Z`. The driver awaited that persisted milestone using filesystem events and read-only SQLite, then released the original real child turn/completed frame at `21:58:16.674218Z`, followed by its two original activity frames. Original/released turn/completed raw-line SHA256: `d1455a3cf6ac368b878eda7c566b4b19af69409df61f7d096186cf6946173e9f`. All three held/released SHA256 pairs match. gate-transport-events.json records original occurrence and delivery times; gated-cancellation-driver.txt records the persisted milestone and release. The late successful frame did not resurrect the parent: its run stayed interrupted, child projection stayed interrupted while preserving EV23840_CANCELGATE_CHILD_DONE, and no server completion message or root continuation appeared. A separate eligible barrier continuation completed at `21:58:52.425Z`; snapshot at `21:59:10.293373Z` still shows exactly one interrupted cancelgate root run and no pending/running effects. Only afterward did an explicit fresh user turn run and return EV23840_CANCELGATE_RECOVERY_OK. Final snapshot at `21:59:29.895993Z` has exactly two cancelgate runs (interrupted original plus explicit recovery) and two barrier runs. No duplicate wakes after late delivery and processing. The initial wrapper used a fixed control socket which a startup catalog probe left behind; two starts failed before any native child existed. That attempt is excluded. The corrected driver uses unique sockets and fresh gate2-home. No repository code was changed. All servers/wrappers/real CLI processes started by this work were stopped by recorded PID and verified checkout cwd. ## Capture scope runtime-head.json, runtime-before.json and runtime-gate2.json contain selected native protocol frames, persisted runs/messages/subagents/provider threads/provider turns, selected committed events and effect/receipt state. processing-boundaries.json preserves the named intermediate/final projections. Only this task's synthetic conversations are included. Driver and source hashes, exact commands, model/options, OS, home IDs and captured PID ownership are recorded. No visual fixtures apply (0/0): this changes server behavior and no render path. Model and harness: gpt-6.1-sol through Codex (evidence collection and read-only proof audit pass 2).
