Codex L2 food-truck orchestrators are killed by the stream-idle watchdog (run_skill.stream_idle_timeout_ms = 600000 → 600s; defaults.yaml:53, _config_dataclasses.py:106) while legitimately blocked on a long-running MCP tool call — specifically run_skill children (make-plan, implement) that routinely run 30–60+ minutes. The kill orphans the healthy child session, fails the dispatch with fleet_l3_no_result_block, and applies the fail label to the pipeline's issue.
Lineage: #1984 covered the same watchdog killing food trucks waiting on merge queue / CI (staged); this is the codex + in-flight-MCP-call variant, which that fix does not cover.
Rollout shows a fully healthy L2: 34 events, 5 mcp_tool_call_end (open_kitchen → bootstrap_clone → claim_and_resolve → create_and_publish → run_skill make-plan), last event 12:02:20Z, then silence while awaiting the make-plan child.
Dispatcher log: stdout idle for 600.0s — firing IDLE_STALL at 05:39:34, Headless session killed. Envelope: fleet_l3_no_result_block, elapsed 2302s.
The make-plan child kept working after the parent was killed (clone file activity continued 30+ minutes past the kill: 2439 files modified in the following hour) — orphaned healthy work.
Why claude-code L2s survive identical spells: the stale detector suppresses on ESTABLISHED port-443 evidence ("JSONL silent for 1202s but ESTABLISHED port-443 — suppressing stale kill", observed repeatedly on the same night's claude dispatches). A codex L2 blocked on a local MCP socket has no port-443 connection and channel_b_capable=False (no JSONL side-channel), so no suppression path applies — the stream-idle kill fired with no suppression attempt logged.
Secondary observation
At kill time the codex NDJSON parser dropped item_type=error events (codex_ndjson_unknown_item_type, sealed enum from #3765; also noted on #4200) — kill-adjacent error payloads are invisible to diagnostics, which materially slowed root-causing this failure.
Expected behavior / fix shapes
In-flight MCP call = alive. The MCP server knows when a run_skill (or any long tool call) is executing for a session — that registry is the truthful liveness signal. Suppress stream-idle/idle-stall kills while a tool call is in flight, backend-independently.
Per-backend or per-session-type stream-idle threshold: an L2 food truck is expected to be stdout-silent for the full duration of each child session; its stream-idle floor should be >= run_skill.timeout (7200s), not 600s.
Add error to the sealed codex NDJSON item enum so kill-adjacent error payloads are captured in diagnostics.
Mitigation in use (loop driver)
AUTOSKILLIT_RUN_SKILL__STREAM_IDLE_TIMEOUT_MS=7200000 on the dispatching environment.
Additional occurrence: claude-code variant via suppression bound (2026-07-07)
The same defect class also kills claude-code L2s: dispatch 045d509c (remediation of #4204) was killed at 1h30m by "Suppression bounded: stale kill after 2402s consecutive suppression (max_suppression_seconds=1800)" while legitimately blocked on its implement child. The port-443 suppression works but is CAPPED below realistic child-session durations (implement/resolve-failures children routinely run 30-90 min). Fix shape 1 ("in-flight MCP call = alive") covers this variant too — while a run_skill call is executing, neither the stream-idle kill, the stale kill, nor the suppression bound should fire. Interim mitigations in use by the loop driver: AUTOSKILLIT_RUN_SKILL__STREAM_IDLE_TIMEOUT_MS=7200000 and AUTOSKILLIT_RUN_SKILL__MAX_SUPPRESSION_SECONDS=7200.
Prior Codex Self-Test Attempt (2026-07-08/09) — blocked by #4215 before implementation
The required Codex self-test was retried after #4199 landed, using the bundled remediation recipe (not remediation-fable) and --backend codex:
env -u AUTOSKILLIT_SESSION_TYPE AUTOSKILLIT_CORE__DEFAULT_MODEL='opus[1m]' \
AUTOSKILLIT_RUN_SKILL__STREAM_IDLE_TIMEOUT_MS=7200000 \
AUTOSKILLIT_RUN_SKILL__MAX_SUPPRESSION_SECONDS=7200 \
autoskillit fleet run remediation --backend codex \

-i source_dir=/home/talon/projects/generic_automation_mcp \
-i post_run_diagnostics=true --timeout-sec 14400
Outcome: dispatch d6d87a72-f14a-4dc8-aca6-4c329ddfd1ec, parent Codex session 019f4498-1f77-70c2-ad4a-d80d40c234b2, failed at the first recipe step (investigate) before implementation began. The clone was preserved at /home/talon/projects/autoskillit-runs/remediation-20260708-185810-891274.
Failure signature: child investigate session 019f4499-47bf-7ba3-b2e6-624dc4d486a2 exited naturally with exit_code=0, but run_skill returned subtype=adjudicated_failure, success=false, fs_writes_detected=false, git_writes_detected=false, and write_call_count=0. Child artifacts:
The child final message said it could not write the normal $investigate report under .autoskillit/temp/investigate/ because the session was read-only. It then produced useful root-cause analysis for this issue and emitted %%ORDER_UP::e284d23b%%, but the recipe could not consume it because the mandatory report artifact was missing.
New blocker filed: #4215, Codex investigate child runs read-only, cannot write required report artifact, and returns adjudicated_failure with zero writes.
Next-round guidance: do not rerun this same Codex remediation --backend codex dispatch until #4215 is fixed or the investigate step is manually routed through a writable provider. Once #4215 is staged/installed, rerun the exact self-test command above and continue this issue's remediation.
Blocker #4215 Resolved Before Retry (2026-07-09 UTC)
The prior Codex self-test failure described above was fixed by #4215 / PR #4216. PR #4216 merged into develop at 2026-07-09T03:39:36Z (7555994c4018bb5f5025bfec6ab0fe5db02b89c3), and the follow-up version-sync commit installed as AutoSkillit 0.10.858 at 1e76bde9af858757374348b357985d468d73c98b.
The fix makes /autoskillit:investigate writable for required report artifacts and gives the bundled remediation recipe an explicit output_dir: '{{AUTOSKILLIT_TEMP}}/investigate' for its first step. Local task test-check, pre-commit, GitHub Actions, and merge queue all passed.
Before retrying this issue, the driver verified no live fleet dispatch process was running and .autoskillit/temp/.hook_config_overlay.json had no quota_guard key, no empty locked-step scope, and no false locked steps. Proceed with the exact bundled remediation --backend codex self-test command above.
Progress made: investigate, rectify, and dry-walkthrough completed successfully. The Codex L2 survived a long stdout-silent child session with stdout_idle_stall_suppressed warnings instead of being killed, which is direct live evidence for the #4202 fix path. The implementation step produced a substantial liveness-policy worktree, then hit context exhaustion. The L2 continued into testing/recovery and reduced local failures from 30 to 23, but then exited with envelope dispatch_status=resumable, reason=fleet_quota_exhausted, and summary: Codex weekly quota exhausted during remediation retries; reset window Jul 12 at 10am America/Los_Angeles.
Because the remaining route is blocked by Codex quota rather than engineering intent, the driver is entering operator-authorized UNCLOGGER mode and continuing manually from the existing worktree in recipe order. Next manual step: run /autoskillit:resolve-failures against the preserved worktree and plan artifact, using the existing MiniMax/claude-code provider route rather than re-dispatching Codex.
Correction to 2026-07-09 Quota Interpretation
Follow-up investigation found the prior phrase "Codex weekly quota exhausted" was imprecise.
The dispatch envelope for f59e3e5b-8609-4d8b-ae3b-ea01d525285b was correctly dispatch_status=resumable, reason=fleet_quota_exhausted, but the exhausted quota was not the parent Codex L2. The parent Codex rollout continued to report roughly 28% five-hour and 10% seven-day usage with no rate_limit_reached_type through the final turn.
The actual 429s came from downstream Claude Code child sessions launched after implementation context exhaustion:
The last child Claude log contains provider-layer metadata: error="rate_limit", isApiErrorMessage=true, apiErrorStatus=429, and text You've hit your weekly limit · resets Jul 12, 10am (America/Los_Angeles). Those recovery steps had provider_used="", while the earlier implement child used provider_used="minimax". Current config maps remediation implement to MiniMax, but not retry_worktree, assess, or merge_gate_assess.
Operational guidance remains: continue manually from the preserved worktree with explicit step_provider=minimax for /autoskillit:resolve-failures; do not re-dispatch into recovery steps that can fall back to Anthropic without provider override coverage.
Because the MCP kitchen was still stale after the installed package changed, the driver continued the recipe's resolve-failures intent manually in the preserved worktree rather than re-dispatching into the Anthropic-backed recovery wall.
Plan artifact: /home/talon/projects/autoskillit-runs/remediation-20260708-205019-355728/.autoskillit/temp/rectify/rectify_codex_l2_liveness_policy_2026-07-08_211800.md
Full gate after follow-up contract fix: task test-check -> PASS (29810 passed, 603 skipped, 44 xfailed), output /home/talon/projects/autoskillit-runs/worktrees/impl-4202-20260708-220503/temp/test-2026-07-09_061035.txt.
Next recipe-tail step: push the worktree branch and run the normal audit/PR/review tail (audit-impl if available, then prepare/compose PR, review, resolve-review, CI, merge queue). If MCP run_skill remains blocked by stale server state, continue the tail manually only as far as the runbook allows and document each action here.
After MCP reload, the driver continued the #4202 recipe tail manually from the preserved worktree rather than re-dispatching into the known downstream Anthropic quota wall.
Mirrored resolved SessionLivenessSpec back into child AUTOSKILLIT_IDLE_OUTPUT_TIMEOUT before runner invocation, including explicit idle_output_timeout=0 removing stale Codex stream-idle hints.
Preserved raw Codex backend payloads on operation-liveness events and on item.started / item.updated metadata.
Current route: continue manual remediation from the audit file. Three disjoint worker subagents were launched for watcher/process tests, fleet/provider-fallback tests, and config/arch/contract guards. Do not open the PR until audit-impl returns GO.
Manual Audit Remediation Round 2 (2026-07-09)
The driver completed the audit-impl NO GO remediation from the preserved worktree and pushed the follow-up coverage commit.
Added the missing liveness contract, core API, protocol, architecture, watcher, Channel-B stale, provider-fallback, and fleet Codex coverage requested by audit.
Added tests/contracts/test_headless_liveness_contracts.py and source-map/docs entries for _headless_liveness.py.
Added architecture guards that keep Codex parent idle behavior sourced from resolved SessionLivenessSpec, not backend child hints or ambient env reads.
Added watcher/process tests proving in-flight operation liveness suppresses stdout idle and Channel-B stale, and clamps child-activity deadline extension to the operation deadline.
Added provider fallback and fleet Codex regressions for stdout-silent MCP activity and fresh per-attempt supervisor state.
Made dispatch wrapper tests deterministic by patching quota wait/refresher dependencies in non-quota server tests; this fixed a full-suite-only timeout where real quota state could sleep long enough for pytest-timeout and surface as fleet_l3_startup_or_crash / CancelledError: transport teardown.
Next route: rerun audit-impl with step_provider=minimax. If it returns GO, continue the PR tail with prepare-pr, compose-pr, review-pr, and resolve-review as directed by the recipe/runbook.
Manual Audit Rerun GO (2026-07-09)
Manual audit-impl was rerun after remediation round 2 with MiniMax provider routing.
Run parameters: step_provider=minimax, order_id=4202-manual-audit2, idle_output_timeout=0, stale_threshold=7200.
Session: 7dd2e5ff-b18a-4850-9967-fd7daa2202bc
Result: verdict = GO / merge approved.
Next route: continue the normal recipe PR tail from branch codex-l2-liveness-supervision-4202: prepare PR metadata, compose/open PR, run review-pr, and route any review findings through resolve-review before CI/merge queue.
Manual PR / Review Tail Continuation (2026-07-09)
After audit-impl returned GO, the driver continued the recipe PR tail manually with MiniMax-backed run_skill steps from the preserved worktree.
compose-pr (step_provider=minimax, order 4202-manual-compose-pr) succeeded; session 596f7f59-8c42-4104-b4ce-2b070a08fc74; opened PR Rectify: Codex L2 Liveness Policy #4217.
First review-pr (step_provider=minimax, order 4202-manual-review-pr-0) posted review comments and returned changes_requested; session 35c6f84d-5602-4bd5-a5c4-7f36d31046f8.
resolve-review initially ran into a read-only source-edit constraint, then the driver manually applied the documented review plan and committed the fixes.
Second review-pr (step_provider=minimax, order 4202-manual-review-pr-1) returned approved_with_comments; session cb0f833b-9c4b-43cb-b70b-3c1a54491ed5.
Final resolve-review (step_provider=minimax, order 4202-manual-resolve-review-2) applied 5 warning fixes, rejected 5 comments, left 5 DISCUSS, resolved/replied to 16 threads, and reported verdict = real_fix; session e8b80f0b-d613-4ad6-9ce6-713951bf76e9.

Issue labels swapped from in-progress to staged.
This completes the required Codex self-test remediation target for #4202.
Rollback / Rerun Correction — 2026-07-09
The previous staged status was incorrect. The Codex-backed #4202 remediation dispatch did not complete the bundled remediation recipe end-to-end and did not persist/review a final analyze-pipeline-health report. It proved the early Codex liveness path through investigate, rectify, and dry_walkthrough, but then hit implementation context exhaustion, failed worktree tests, and stopped when downstream Claude Code recovery sessions hit Anthropic weekly 429s.
Manual UNCLOGGER continuation produced PR #4217, but that manual PR/review/CI/merge tail cannot count as the #4202 Codex self-test. The success condition requires the Codex backend to complete the bundled remediation recipe independently, including post-run diagnostics/health analysis.
Kept only a separate test-only stabilization so dispatch tests do not use the live Anthropic quota path: d89fb2aa0fa42d8f53830ccf53afa7da2cdf2853 (test: isolate dispatch tests from quota state). This does not restore the Rectify: Codex L2 Liveness Policy #4217 liveness implementation.
Reset labels by removing staged; current labels should be bug + recipe:remediation.
Validation after rollback: pre-commit run --all-files PASS; focused dispatch tests PASS (23 passed, temp/test-2026-07-09_100810.txt); full task test-check PASS (29800 passed, 604 skipped, 44 xfailed, temp/test-2026-07-09_100830.txt).
Next required route: rerun #4202 the right way. If the Codex backend cannot complete the recipe, manual work is limited to remediating the blocker that prevents a later autonomous Codex completion; manual recipe/PR/review/merge steps cannot substitute for the required Codex self-test.
Rerun Attempt Interrupted — 2026-07-09 Codex Alias Blocker
Fresh Codex self-test dispatch 4e6fbbea-f4fc-4176-bfce-34cb09157a68 was started after the #4217 rollback, but it was intentionally interrupted before it could count as a valid #4202 self-test. Evidence from the process tree showed the Codex L2 food-truck process launched with --model gpt-5.4, which violates the active operator constraint to use gpt-5.5 and avoid 5.4/mini routes.
This is a separate pipeline/backend blocker, now tracked as #4218. Local dispatch state was marked interrupted with reason operator_stopped_for_forbidden_gpt_5_4, and the stale in-progress label was removed from #4202. #4202 remains bug + recipe:remediation and must be rerun only after #4218 is merged/installed.
Manual work on #4218 is limited to remediating this blocker so a later #4202 Codex backend run can complete autonomously. It does not count as completing #4202.
Autonomous Rerun Preflight — 2026-07-09 13:26 PDT
After #4218/PR #4220 installed AutoSkillit 0.10.861, the Claude marketplace plugin cache needed a local administrative refresh before MiniMax + claude-code worker steps could safely launch. The cache was refreshed with AUTOSKILLIT_AGENT_BACKEND__BACKEND=claude-code autoskillit install --scope user; this performed only local marketplace/plugin administration and did not launch an Anthropic model session.
installed_plugins.json points autoskillit@autoskillit-local at /home/talon/.claude/plugins/cache/autoskillit-local/autoskillit/0.10.861 with version 0.10.861.
AutoSkillit's runtime marketplace resolver returns that versioned path, and version_info reports package 0.10.861, plugin manifest 0.10.861, match=true.
A restarted MCP server opens the kitchen successfully and reports AutoSkillit 0.10.861.
Direct kitchen_status invocation from this Codex client returns Unknown tool: 'kitchen_status'; this is a client/tool-visibility discrepancy, not a package/cache mismatch. The independent runtime resolver check above verifies the same version contract used by a newly launched fleet server.
The bundled remediation recipe validates under the exact dispatch-style ingredient shape with valid=true, dispatch_feasible=true, and zero error-severity findings. A schema-only call that forced post_run_diagnostics=true while deferring every other guarded ingredient exposed a separate pruning-filter edge case, but the real fleet validation path resolves defaults and is unaffected.
No autoskillit fleet process is running.
.autoskillit/temp/.hook_config_overlay.json is absent, so no stale ingredient locks or quota guard remain.
Next action: launch a completely fresh bundled remediation --backend codex run with post_run_diagnostics=true, then verify the live L2 process uses gpt-5.6-sol with model_reasoning_effort=xhigh. This dispatch must complete the recipe and health-analysis tail autonomously; manual completion of its engineering/PR tail is not an allowed success route.
Rerun Interrupted — 2026-07-09 Sol Effort Override Key
Fresh dispatch 0b23e627-a221-4948-8f07-5792235a8f2f was launched after the 0.10.861 reload and stopped before engineering. Live process evidence showed the L2 using --model gpt-5.6-sol -c model_reasoning_effort=high. The model family was correct, but #4202 is an Opus-class serious remediation and requires xhigh.
This was a runbook configuration-key error, not a failure of the Sol alias mapping. The command used AUTOSKILLIT_CORE__DEFAULT_MODEL='opus[1m]', which is ignored by the config loader and leaves model.default=sonnet. Direct installed-package probes established:
The dispatch record is marked interrupted with reason operator_stopped_for_sol_effort_downgrade, its process tree is gone, and the transient fail label was removed. The handoff command now uses AUTOSKILLIT_MODEL__DEFAULT='opus[1m]'.
Next action: start another completely fresh dispatch with the corrected key and require live gpt-5.6-sol + model_reasoning_effort=xhigh evidence before allowing the autonomous recipe to continue. Do not resume this interrupted session.
Autonomous Codex Rerun Active — 2026-07-09 13:32 PDT
Fresh bundled-remediation dispatch f6b3f866-1f83-487d-80e0-1ff00a4f74c5 is the current valid #4202 self-test.
Fleet command uses AUTOSKILLIT_MODEL__DEFAULT='opus[1m]', the 7200-second stream-idle/suppression overrides, --backend codex, and post_run_diagnostics=true.
Live L2 process PID 3276930 was process-verified with --model gpt-5.6-sol -c model_reasoning_effort=xhigh.
The L2 environment carries AUTOSKILLIT_DISPATCH_ID=f6b3f866-1f83-487d-80e0-1ff00a4f74c5, AUTOSKILLIT_HEADLESS=1, and AUTOSKILLIT_AGENT_BACKEND__BACKEND=codex.
This run must complete the entire recipe, including PR/review/merge gates and the final analyze-pipeline-health step, without the driver taking over its engineering tail. If it exposes another pipeline blocker, harvest that failure, remediate only the blocker, and rerun #4202 fresh.
Dispatch f6b3f866-1f83-487d-80e0-1ff00a4f74c5 ran the bundled remediation recipe on the Codex backend for 2h47m. The L2 and all serious Codex stages were process-verified on gpt-5.6-sol with model_reasoning_effort=xhigh; worker-write and recovery stages used the configured MiniMax + claude-code route. No Anthropic-backed step was used.

The branch is partial, not an accepted implementation. Health analysis found that the reproducer's 1.2-second simulated stall ends before the watcher's first 5-second poll and that production observations use hard_deadline_monotonic=0.0, so the green test was a false positive. audit-impl independently found that the seven-slice liveness architecture remained incomplete.
Terminal failure:
The audit-remediation dry walkthrough received only the remediation plan, not the current remediation_path. It treated REQ-001 through REQ-042 as unmapped, made zero writes, and asked to be rerun with the audit artifact. The L3 envelope reported:
Pipeline failed after the remediation dry-walkthrough did not receive the required remediation_path; diagnostics completed and the clone was preserved.
Health analysis confirmed four bugs: the false-positive liveness test/inert production deadline, incomplete implementation hidden by green tests, missing remediation-path propagation, and search-command guard false positives. It also recorded implementation/retry context exhaustion, skipped audit parallel/chunk discipline, Codex NDJSON error item drift, one recoverable 1-second wait error, and read-only/offline rectify verification limits.
No JSON health report exists because #3209 supplied an empty dispatch ID. The reviewed health text is preserved in the final agent_message of rollout /home/talon/.local/share/autoskillit/logs/codex-sessions/2026/07/09/rollout-2026-07-09T16-11-34-019f4926-9abc-74f0-bd84-effbf70e1f99.jsonl.
Next-round guidance: do not reimplement from scratch and do not treat the five commits as complete. Fix and install #4185 and #3209 first. Then launch a fresh bundled-remediation Codex round that adopts remote branch .../4202-4, completes the missing liveness architecture, opens/finishes its own PR, and persists/reviews the dispatch-scoped health report autonomously.
Problem
Codex L2 food-truck orchestrators are killed by the stream-idle watchdog (
run_skill.stream_idle_timeout_ms= 600000 → 600s;defaults.yaml:53,_config_dataclasses.py:106) while legitimately blocked on a long-running MCP tool call — specificallyrun_skillchildren (make-plan, implement) that routinely run 30–60+ minutes. The kill orphans the healthy child session, fails the dispatch withfleet_l3_no_result_block, and applies the fail label to the pipeline's issue.Lineage: #1984 covered the same watchdog killing food trucks waiting on merge queue / CI (staged); this is the codex + in-flight-MCP-call variant, which that fix does not cover.

The port-443 suppression works but is CAPPED below realistic child-session durations (implement/resolve-failures children routinely run 30-90 min). Fix shape 1 ("in-flight MCP call = alive") covers this variant too — while a run_skill call is executing, neither the stream-idle kill, the stale kill, nor the suppression bound should fire. Interim mitigations in use by the loop driver: AUTOSKILLIT_RUN_SKILL__STREAM_IDLE_TIMEOUT_MS=7200000 and AUTOSKILLIT_RUN_SKILL__MAX_SUPPRESSION_SECONDS=7200.Prior Codex Self-Test Attempt (2026-07-08/09) — blocked by #4215 before implementation

investigate,rectify, anddry-walkthroughcompleted successfully. The Codex L2 survived a long stdout-silent child session withstdout_idle_stall_suppressedwarnings instead of being killed, which is direct live evidence for the #4202 fix path. The implementation step produced a substantial liveness-policy worktree, then hit context exhaustion. The L2 continued into testing/recovery and reduced local failures from 30 to 23, but then exited with envelopedispatch_status=resumable,reason=fleet_quota_exhausted, and summary: Codex weekly quota exhausted during remediation retries; reset window Jul 12 at 10am America/Los_Angeles.Because the remaining route is blocked by Codex quota rather than engineering intent, the driver is entering operator-authorized UNCLOGGER mode and continuing manually from the existing worktree in recipe order.

The dispatch envelope for

Rollback / Rerun Correction — 2026-07-09
The previous staged status was incorrect. The Codex-backed #4202 remediation dispatch did not complete the bundled remediation recipe end-to-end and did not persist/review a final
analyze-pipeline-healthreport. It proved the early Codex liveness path throughinvestigate,rectify, anddry_walkthrough, but then hit implementation context exhaustion, failed worktree tests, and stopped when downstream Claude Code recovery sessions hit Anthropic weekly 429s.Manual UNCLOGGER continuation produced PR #4217, but that manual PR/review/CI/merge tail cannot count as the #4202 Codex self-test. The success condition requires the Codex backend to complete the bundled remediation recipe independently, including post-run diagnostics/health analysis.
Actions taken:

If the Codex backend cannot complete the recipe, manual work is limited to remediating the blocker that prevents a later autonomous Codex completion; manual recipe/PR/review/merge steps cannot substitute for the required Codex self-test.
Rerun Attempt Interrupted — 2026-07-09 Codex Alias Blocker
Fresh Codex self-test dispatch
4e6fbbea-f4fc-4176-bfce-34cb09157a68was started after the #4217 rollback, but it was intentionally interrupted before it could count as a valid #4202 self-test. Evidence from the process tree showed the Codex L2 food-truck process launched with--model gpt-5.4, which violates the active operator constraint to usegpt-5.5and avoid 5.4/mini routes.This is a separate pipeline/backend blocker, now tracked as #4218. Local dispatch state was marked
interruptedwith reasonoperator_stopped_for_forbidden_gpt_5_4, and the stalein-progresslabel was removed from #4202. #4202 remainsbug+recipe:remediationand must be rerun only after #4218 is merged/installed.Manual work on #4218 is limited to remediating this blocker so a later #4202 Codex backend run can complete autonomously. It does not count as completing #4202.

Dispatch
f6b3f866-1f83-487d-80e0-1ff00a4f74c5ran the bundledremediationrecipe on the Codex backend for 2h47m. The L2 and all serious Codex stages were process-verified ongpt-5.6-solwithmodel_reasoning_effort=xhigh; worker-write and recovery stages used the configured MiniMax + claude-code route. No Anthropic-backed step was used.Completed autonomously:

Health analysis found that the reproducer's 1.2-second simulated stall ends before the watcher's first 5-second poll and that production observations use
hard_deadline_monotonic=0.0, so the green test was a false positive.audit-implindependently found that the seven-slice liveness architecture remained incomplete.Terminal failure:
The audit-remediation dry walkthrough received only the remediation plan, not the current
remediation_path. It treated REQ-001 through REQ-042 as unmapped, made zero writes, and asked to be rerun with the audit artifact. The L3 envelope reported:Blockers activated from this run:
remediation_pathinwith:but therun_skillschema cannot deliver that unsupported argument; the bilateral semantic rule validates an inert key.--dispatch-id=and explicitly skipped writing the JSON health report, even though the L2 process had the fleet dispatch ID.Health analysis confirmed four bugs: the false-positive liveness test/inert production deadline, incomplete implementation hidden by green tests, missing remediation-path propagation, and search-command guard false positives. It also recorded implementation/retry context exhaustion, skipped audit parallel/chunk discipline, Codex NDJSON
erroritem drift, one recoverable 1-second wait error, and read-only/offline rectify verification limits.No JSON health report exists because #3209 supplied an empty dispatch ID. The reviewed health text is preserved in the final

Fix and install #4185 and #3209 first. Then launch a fresh bundled-remediation Codex round that adopts remote branch
.../4202-4, completes the missing liveness architecture, opens/finishes its own PR, and persists/reviews the dispatch-scoped health report autonomously.
