Defect: Complete turn cancellation within the 5 s terminal bound

[Niko4417]

Parent Epic: #98

Planning contract

• Contract version: v95

• V95 test-only fixture safety: Parent185/child95/consumer98 need readiness. Freeze signed6459e2c029fb3f906efe2454401dcac8e0cffaec/runtime SHA256 f8603bd5bed9cd0f1459ebe3ad4db92352df5513868642ff42d87f742aead8e1. Preserve V94 five intended REDs before fence, GREENs, signed refinements/failures5543977763/5544196009/5544482455; V94 archive 5544514293. Canonical quality2 failed branch floor; diagnostic2050/2468=83.063209% is not canonical data/qualification. Historical timing/provider causes unproven; old ledgers/caps sealed.

  Scope only cfg(test) safety scaffolding in native/crates/keiko-host-macos/src/runtime.rs used by readiness5, a188_real_cancelled_transition and a188_refresh_cancellation_real_user_during_refresh; plus six current readiness values/assertions in quality/codex-tracer-acceptance.mjs and its test. Productive runtime/fence unchanged. No unrelated tests, policy, dependencies, gates, exclusions, skips, driver, UI or budget changes.

  Extract existing test-only coordination, exact-window/cutoff, update-sequence, cleanup-proof and owner-disposition predicates; keep real fixtures wired to them. Preserve logical checks, lazy short-circuit and observation order. Share only equivalent test retention/release guards; retain unproven resources and release idempotently on normal/unwind paths. No metric-only rewrites, removed safety checks or fabricated native identity/cleanup.

  Add a188_fixture_safety_ mandatory cases: readiness_coordination_requires_all_observations; readiness_window_requires_exact_authority; readiness_cleanup_requires_all_retirement_evidence; retention_requires_explicit_cleanup_proof; release_is_idempotent_on_drop; turn_update_sequence_rejects_incomplete_or_reordered; turn_cleanup_requires_every_observed_proof; refresh_cleanup_requires_retirement_and_absence. Cover missing/changed source/full window/cutoffs, absent coordination/cleanup/settlement, wrong/reordered/duplicate/late events and stop reason. Cleanup refusal uses inactive RuntimeHost::unavailable_for_test, individually unavailable locks and resource-free control/running/work states; never unretired live children. Drop witnesses test ownership; actual local primitives test release/unwind. Synthetic predicate inputs are unit-only, never substituted for genuine Host/native observations. No unsafe identity, network, sleeps or extra production probe. Allow refinements within this safety-helper class; retain every attempt. Raw counters promise no aggregate gain.

  Preserve readiness5, literal Host acceptance/full-window equality/unchanged cutoffs, raw-before-Host result, initialized-write/quarantine non-admission, account-write guard span, bounded joins and authenticated process/reader/work cleanup. Preserve V87 real paths/assertions/budgets, PROCESS_TEST_LOCK/default scheduling. V94 REDs prove its unchanged fix; new tests cover existing scaffolding, not a claimed new production failure. Audit extraction/call-site equivalence/test design before execution.

  Rebind #98v185/#188v95/#104v98 using actual accepted fingerprints/current assertions; stale fixtures unchanged. Run cargo +1.92.0 test --locked --manifest-path native/Cargo.toml -p keiko-host-macos a188_fixture_safety_ -- --nocapture, then unchanged focused readiness5, Clippy workspace/all-targets -D warnings, policy7, real-transition1, exact provider-crash1, application23 plus originalhost438 and all new safety tests, Node acceptance17. Capture full redacted outputs, exact commands/exit/inventories/source/diff/runner/log hashes; no concurrent Rust, offline/default scheduling, no RUST_TEST_THREADS. Each failure/incomplete attempt stops for investigation before another scoped refinement; no arbitrary attempt cap. New productive defect/boundary/scope/gate/deadline change requires replan.

  Direct GREEN/audit and signed clean three-file checkpoint precede npm ci --ignore-scripts; npm run quality; npm audit --audit-level=high; npm run acceptance:macos/all platform gates on Node24.18/npm11.16. Native branches/functions/lines/regions remain85%. Source-bound diagnostics guide only scoped tests, never grant gate credit. No partial-green publication.

  Exact-head local GREEN precedes matching package/readiness physical13, genuine IME/appearance/scaling/motion/accessibility, fresh human VoiceOver exactly-one hearing, real cancellation/crash recovery, no effects/residue and restored settings. Preserve single-display/no-external claim, one-hour freshness/five-minute tolerance and three consecutive unchanged no-argument npm run acceptance:codex-tracer:macos passes, each20 first-visible/20 fresh picker/4 projections with unchanged5,000/100/750ms ceilings. No historical reuse. Local journey/quality/current-head audit P0/P1/P2=0 precedes normal non-force publication; fresh Codex review, zero unresolved findings/conversations and exact-head remote gates precede handoff. PR211 target unchanged; inactive child/dev human-only, no activation/merge automation. Defect: Preserve fail-closed startup recovery ownership #213 waits actual Defect: Complete turn cancellation within the 5 s terminal bound #188 integration; Integrated packaged macOS acceptance for the Codex tracer #104 owns final integrated acceptance. Separate in-app Quit finding4897107465 is not authorized for repair here and remains an epic handoff blocker.

• Historical V87 (execution superseded by V88) narrow classified-refresh cancellation correction and requalification: Matching parent v177/child v87/consumer v90 supersede earlier execution allowlists for this bounded correction under the operator's autonomous epic-quality repair authority. Start from signed productive base 535b8fa3e286b3e53ddfa9019a6fda065fc6f20a, with exact retained V85/V86 diagnostic runtime.rs SHA-256 f6a9e51865454432253e3f17578269d95d6247df9f9acdc08abbef51ccce1e08 and full unstaged diff SHA-256 4e1465e99a4921eff1813a476ed4e1c608e1e171573131da68040a78feb709b6. Independent architecture, security and evidence audits confirmed the real V86 attempt-2 RED at Defect: Complete turn cancellation within the 5 s terminal bound #188 (comment): actual leader metadata size mismatch, actual WNOWAIT Ok(false), retained Unavailable and rejected leader refresh selected ContainmentFailed/InternalFailure before already-accepted User cancellation; full RuntimeHost accepted-window equality, genuine streaming/Stopping order, cutoff, authenticated cleanup and retirement passed. Attempt 1 passed; execution stopped at attempt 2. SizeMismatch does not distinguish zero, short or failed native metadata results, and NotExited is only that observation. This proves the fixture's cancellation/refresh terminal-decision defect, not the exact historical physical incident or renderer-originated Host acceptance path. The original provider-crash failure remains separately unresolved; neither this repair nor unrelated green reruns may claim it explained. Preserve every prior failed attempt, all twenty V85 no-RED results, V86 runners/claims/redacted logs/stop records, physical evidence and exact hashes. Before altering diagnostic bytes, archive and hash the exact source and full diff outside productive roots; no discarded evidence or reused attempt registry.

  Authorized productive scope is the owning private implementation and colocated tests in native/crates/keiko-host-macos/src/runtime.rs, plus only the six existing readiness identity fields and matching assertions in quality/codex-tracer-acceptance.mjs and quality/codex-tracer-acceptance.test.mjs after all three new contracts are accepted. The six fields are cancellationReadinessVersion/Fingerprint, issueReadinessVersion/Fingerprint and parentReadinessVersion/Fingerprint; bind them to the actual accepted v87/v90/v177 fingerprints, not guessed values. No other acceptance identity, schema, driver, frontend, dependency, capability, source root, policy, gate, coverage floor or permission boundary changes. Exact target remains epic/98-codex-tracer through PR Fix #188 cancellation terminal bound #211; retain the dedicated codex/188-cancellation-terminal-v68-recovery worktree/branch and normal non-force publication path. No new architecture boundary or reuse from Existing Keiko is introduced.

  The smallest correction is one shared private typed refresh/cancellation admission policy used by both run_turn_protocol and readiness run_protocol. Preserve the actual refresh and its native-call count/order, errno capture, lock ordering, process identity/inventory and all existing boolean consumers. A private classified metadata/retained-identity/refresh result may preserve distinctions currently erased by Option/bool; compatibility wrappers keep every existing Current/Reused/Unavailable and success/failure mapping unchanged. In particular, valid matching identity remains Current, changed start identity remains Reused, and both metadata-size and metadata-PID anomalies followed by WNOWAIT Ok(true) retain today's Current unreaped-child fallback. Do not convert those successful observations into failures. A failed refresh is narrowly eligible for cancellation admission only when the actual authenticated leader metadata observation is SizeMismatch and the existing WNOWAIT returns Ok(false), and the authoritative currently accepted cancellation is User. Call this unavailable-before-observed-exit, not proven transient. It is not identity authentication, liveness, absence or completed cleanup. Positive PID/start mismatch or reuse, WNOWAIT error, missing leader, poisoned ownership, retained-member uncertainty and descendant enumeration failure remain noneligible and keep original containment precedence even with User cancellation. No blanket false-refresh-to-cancel conversion. Successful-refresh cancellation behavior remains unchanged for every existing reason.

  Observe authoritative cancellation after the selected refresh has released its locks, using one shared decision policy and no cancellation read under owned-process locks; include cancellation accepted before or during refresh. The turn and readiness loops retain their distinct existing state mappings, exact request/generation/token validation, first-source/deferred-control failure priority, Stopping behavior and cleanup paths. Never mint, replace, refresh or infer a cancellation token. No new signal authority, skipped refresh, signal suppression, inventory clearing, externally reaped child, deadline or retry-budget extension, forward protocol effect after accepted cancellation, late-terminal rewrite, or post-hoc containment remapping. Authenticated process-tree cleanup, owned-member/descendant proofs, reader retirement, work-root removal, strict retry admission and publication remain unchanged. Failed or uncertain cleanup/retirement must remain a failure with ownership retained, never qualifying Cancelled success. A later successful cleanup cannot justify hiding an earlier noneligible discovery failure.

  Use a behavior-preserving private extraction and failure-first deterministic tests prefixed a188_refresh_cancellation_ that exercise the same production admission owner wired into both loops. First prove desired eligible-User behavior RED before enabling that exception, retaining exact command/source/diff/output. Synthetic classified policy inputs are labeled synthetic and are not native/process-cleanup evidence. Cover Ready with all existing cancellation reasons; the precise eligible failure with User versus absent/non-User cancellation; all noneligible metadata/identity/WNOWAIT/ownership/member/enumeration failures; existing Ok(true) Current fallbacks; control poisoning/deferred containment; actual wrong/stale request rejection and duplicate/multiple cancellation without token replacement; before/during-refresh cancellation; shared turn/readiness orchestration; exact token correlation, one final Stopping after genuine StreamingStarted, terminal uniqueness and unchanged cutoffs; failed cleanup/retirement without early retry; and fresh-owner retry only after strict cleanup. No fake native identity, WNOWAIT, process inventory or cleanup proof is permitted for real-process integration claims. Real normal-TERM regression retains the authentic V86 fixture, immediate worker release and real native observations; do not wait for stable child exit to obtain green.

  After the independently reviewed correction and deterministic matrix are green, permit at most twenty explicit sequential post-fix real-TERM diagnostic checks on one frozen source through a separately reviewed fresh source-bound runner using cargo +1.92.0 test --locked --manifest-path native/Cargo.toml -p keiko-host-macos a188_real_cancelled_transition_during_ownership_refresh_diagnostic -- --nocapture. This is a new post-fix verification registry, never a restart of V86. Retain every complete redacted result and stop on the first non-Cancelled/UserCancelled terminal, compilation/setup/correlation/cleanup/cutoff failure or zero match; twenty complete passes are required before advancing. Preserve the original diagnostic oracle and completed selected-refresh/token prerequisites; an eligible refresh rejection followed by correct User cancellation is a valid post-fix result only with all original cleanup/order/cutoff conditions. Then retain a compact genuine cancellation regression, remove diagnostic-only observer/trace output and redundant V85/V86 diagnostic tests through a reviewed cleanup diff, and keep only the smallest cfg(test) coordination required by ongoing regression. Archive original diagnostic bytes first; old evidence remains historical. No diagnostic/test capability may enter the release package.

  Deterministic focused command: cargo +1.92.0 test --locked --manifest-path native/Cargo.toml -p keiko-host-macos a188_refresh_cancellation_ -- --nocapture. The retained permanent real regression uses prefix a188_real_cancelled_transition and the same focused Cargo filter after diagnostic cleanup. Run stable 1.92.0 formatting/static checks and affected host/application tests offline with no concurrent host test process, then fresh npm ci --ignore-scripts, npm run quality, npm audit --audit-level=high and npm run acceptance:macos using exact Node 24.18.0/npm 11.16.0. Existing declared native/platform/package gates and coverage floors remain mandatory. Preserve failures rather than rerun-to-green. This contract authorizes the established tests and bounded repair of confirmed same-scope construction/regression findings, not a new hypothesis or unrelated production repair. An unexpected product failure, unsupported causal assumption or semantic scope change requires evidence-driven diagnosis and new readiness before expanded work. Continue the separately required original provider-crash investigation with exact assertion capture; it is not waived or silently attributed to this correction.

  After focused and complete local gates pass, permit signed local checkpoint/qualification commits and current-source package preparation for fresh physical acceptance, final audit and normal publication in the existing PR. Preserve all V83 single-display allowance and V173 actual stable topology policy: no required external monitor, no fabricated multi-display evidence, unique bound app window, matching automated/reference/physical topology and explicit unverified coverage. Preserve all thirteen physical-v2 checkpoints, genuine Unicode/IME/appearance/contrast/reduced-motion/scaling observations, actual VoiceOver with fresh human-confirmed exactly-one cancellation announcement, current signed source/package/readiness binding and existing freshness limit, timing, zero effects/descendants/residue and restoration obligations. No old record may be freshened or relabeled. Require at least three consecutive cancellation tranches, each one unchanged npm run acceptance:codex-tracer:macos invocation with all twenty first-visible samples, twenty fresh-launch picker samples and four local projections; no selective checkpoint command or substituted wrapper. Defect: Complete turn cancellation within the 5 s terminal bound #188 owns only its cancellation-tranche credit; Integrated packaged macOS acceptance for the Codex tracer #104 alone owns final uninterrupted integrated acceptance after actual Defect: Complete turn cancellation within the 5 s terminal bound #188 and Defect: Preserve fail-closed startup recovery ownership #213 integration. Require full current-head independent audit P0=P1=P2=0, exact-head remote gates, fresh Codex reviews and settlement of all real findings/conversations before clean handoff. Normal non-force push must preserve existing remote ancestry; no direct epic/dev write, no protected-branch merge, no provider auto-merge. The guarded child-merge operation remains inactive and unavailable; child integration stays human-only until protected activation independently authorizes the guarded route. Dev remains human-only.

• Historical V86 (execution superseded by V87) real cancellation-transition observation, diagnosis only: Matching parent v176/child v86/consumer v89 supersede earlier execution allowlists solely for this next bounded technical diagnosis under the operator's autonomous epic-quality repair authority. Freeze productive signed base 535b8fa3e286b3e53ddfa9019a6fda065fc6f20a, tree a1a6364130ec7e6722d55af1e7c4f2cd2434b055; the starting worktree deliberately retains the unchanged, unstaged 257-line V85 cfg(test) diagnostic addition, runtime.rs SHA-256 5ad1a53b5c9cee0c31e7fb018bbb5b2c6ff19facc8110305a07f9f671c9d8c65 and complete binary diff SHA-256 2a62fca0ff4c8649a8fbf44302f8db28ba54eb0bd5d95a5bdd89d3ad3bffdba9. Preserve that diagnostic test and its existing hook unchanged, every prior failed attempt, and all twenty valid V85 no-RED results at Defect: Complete turn cancellation within the 5 s terminal bound #188 (comment). V85 is exhausted and cannot be rerun under this phase. Those results show only that the stable already-exited real child fixture did not reproduce the failure; they do not rule out a transition race or explain the physical cancellation failure at issuecomment-5538790537. The prior exact-535b complete quality, zero-high-vulnerability audit and packaged acceptance passes remain historical evidence, not qualification for new diagnostic bytes. The separately retained original provider-crash failure remains unresolved, unreproduced and not claimed fixed. No root cause or productive repair is accepted. The single declared hypothesis is that real native identity or enumeration observations during normal TERM cancellation, before exit has stabilized, can make the actual protocol ownership refresh reject while exact User cancellation is already accepted. Cancellation/control containment remains an alternative to distinguish, not an assumed cause. Permit only additive cfg(test)-gated observation/coordination code and one new real-fixture test a188_real_cancelled_transition_during_ownership_refresh_diagnostic within native/crates/keiko-host-macos/src/runtime.rs. Reuse the existing genuine initialize/account/thread/turn scripted runtime, published authenticated process group and post-streaming hook. The worker may pause only at that existing loop entry, after the RuntimeControl action_guard naturally drops and the existing post-action cancellation check runs unchanged. The test invokes exact cancel_request for its real request, records the accepted User cancellation from the existing owning seam, then immediately releases the held worker into the real next refresh without waiting or polling for child exit, without a separate identity/enumeration probe before release, and without fabricating any observation. The script uses normal TERM exit. Do not poison a lock, add a descendant, alter process inventory or identity, externally reap the owned child, suppress a signal, compose a terminal outcome, or substitute unavailable/reused classifications. The permitted observation implementation is one per-ActiveRuntime opt-in sink with scoped test-only thread-local observation on the actual protocol worker, active solely around the selected next run_turn_protocol ownership refresh. Use scoped guards to correlate actual refresh entry/result and leader, retained-owned-member or descendant-discovery roles. Observe existing native metadata validation, existing WNOWAIT result if actually consulted, retained identity classification, owned-process presence if actually consulted, enumeration result and precise refresh rejection branch. Preserve native-call count, function signatures and non-test control flow: no duplicate native probe, replacement syscall, changed result, changed return branch, or additional cancellation read under an owned-process lock. In particular, preserve errno capture: after a failed native call, do not log, allocate or lock before the existing io::Error::last_os_error has captured it. A cfg(test) observation guard may assign plain closed enums in a return branch and emit on Drop only after the actual return Result, including its original error, is constructed. The sink has a fixed, declared finite event capacity and explicit overflow flag, uses no payloads or native object dumps, and captures only this refresh; missing, ambiguous or overflowed correlation is a prerequisite stop, never RED or pass. Restore scoped thread-local state on every exit, including panic, and do not leak observations into another runtime or worker. Emit only after worker join and authenticated cleanup/retirement assessment: bounded refresh ordinal/role; metadata valid/size-mismatch/identity-mismatch; WNOWAIT not-consulted/exited/not-exited/error; retained current/reused/unavailable; presence not-consulted/absent/present/unavailable; enumeration not-consulted/ok/error; closed exact refresh result/rejection category; accepted cancellation source before release and in outcome.cancellation returned by that exact run; full AcceptedRuntimeCancellation/window equality between the owning-seam capture before release and that returned outcome.cancellation, emitted only as a match boolean without logging object values, timestamps or identifiers; do not read the active cancellation window after run_turn because finish_request legitimately clears it; final state/reason; existing-cutoff result; genuine StreamingStarted then UserCancelled Stopping order/count; cleanup and owner-retirement booleans; overflow/correlation outcome. Not-consulted values describe absence of an actual call, never an invented native result. No process IDs, paths, timestamps, raw errno values, request/protocol/task content, credentials, endpoints or native structs enter diagnostic output or evidence. Closed observed categories, including unavailable, must not be replaced by desired values. Failure-safe teardown must release all held channels on every prerequisite/assertion failure, join or retain an authenticated cleanup owner, and reconcile real owned processes before removing a fixture; failed cleanup cannot yield no-RED or a qualifying regression. Preserve existing cancellation and coordination guards: no sleeps, increased timeout/budget, hidden retry or suite serialization. The unchanged accepted oracle is Cancelled/UserCancelled with exactly one accepted Stopping after genuine StreamingStarted, within the existing cutoff, with authenticated cleanup, no descendants/residue/effects and owner retirement. Do not weaken assertions to match an unexpected terminal. Independent read-first source and diagnostic review is mandatory before execution, including observation noninterference/errno and failure-safe teardown. The sole execution command is cargo +1.92.0 test --locked --manifest-path native/Cargo.toml -p keiko-host-macos a188_real_cancelled_transition_during_ownership_refresh_diagnostic -- --nocapture, offline, with no concurrent host tests. Permit at most twenty explicit one-at-a-time attempts for this single declared transition hypothesis, retaining exact command, source/full-diff hashes, redacted full output, exact one-test match, exit and closed scalar trace for every attempt. A zero match, compilation/setup failure, missing exact accepted User cancellation or unequal/missing full accepted window/token correlation with outcome.cancellation, absent genuine streaming/selected refresh, malformed or overflowed trace, failed prerequisite/cleanup or timing guard is a prerequisite stop, not an identified product regression or pass. Stop immediately on the first genuine assertion-failing terminal RED with completed prerequisites, on any prerequisite stop, or after twenty no-RED attempts; there is no implicit second hypothesis or automatic retry budget. A RED candidate needs independent source/audit analysis that identifies the exact executed owning branch and distinguishes an actual native observation failure from control containment before any corrective contract can be proposed. Retain the patch and all evidence, then stop for a new successful semantic readiness contract before productive implementation, broader diagnosis, qualification or delivery. No other tracked file, existing assertion, production-compiled behavior, non-test helper, frontend, driver, schema, dependency, policy, coverage floor or permission boundary may change. No six qualification-identity updates, staging, commit, whole-quality run, physical/canonical run, push, PR publication/state change, review settlement or merge is authorized; this diagnostic has zero qualification credit. Preserve every V83 single-display physical requirement and explicit unverified external/multi-display coverage, current-source/package/readiness binding, unique window/stable topology, actual Unicode/IME/visual observations, fresh human-confirmed one-count VoiceOver, timing, zero effects/descendants/residue, restoration, three consecutive canonical tranches, full local/platform/remote gates and final zero-findings audit for later accepted corrective delivery. Unlimited general orchestration does not waive this diagnostic cap or semantic revalidation. Defect: Preserve fail-closed startup recovery ownership #213 waits for actual Defect: Complete turn cancellation within the 5 s terminal bound #188 integration, Integrated packaged macOS acceptance for the Codex tracer #104 alone owns final integrated acceptance, the inactive guarded child-merge operation remains unavailable, and dev remains human-only.

• Historical V85 (execution superseded by V86) cancellation-to-refresh diagnosis only: Freeze signed clean 535b8fa3e286b3e53ddfa9019a6fda065fc6f20a, tree a1a6364130ec7e6722d55af1e7c4f2cd2434b055. The exact-head complete local quality, high audit with zero vulnerabilities and packaged macOS acceptance passed; retain that evidence and every prior failure and diagnostic attempt without converting them into a successful retry explanation. The subsequent real physical failure is recorded at Defect: Complete turn cancellation within the 5 s terminal bound #188 (comment): normal completion, controlled crash and later retry were observed; the first cancellation lacks audible VoiceOver proof; the second reached streaming and stopping, then observe-cancelled rejected an internal-error terminal as containment-failed. Neither the displayed runtime-ended text nor the closed failure category proves process cleanup, a prohibited provider action, VoiceOver causation, or an identified root cause. No valid physical record, human-confirmed terminal announcement count or canonical cancellation tranche exists. Under the operator's explicit autonomous epic-quality repair authority, matching parent v175/child v85/consumer v88 supersede earlier execution write and delivery allowlists solely for bounded evidence-driven diagnosis, as required by the current defect template for a not-yet-reproducible finding. Permit only one cfg(test) ActiveRuntime coordination field, install_turn_post_streaming_before_refresh_hook_for_test, one cfg(test) hook call at the existing loop entry before ownership refresh, installed only by the test callback after observing genuine StreamingStarted so earlier loop entries have no hook, and one new test a188_real_cancelled_exit_before_ownership_refresh_diagnostic, all within native/crates/keiko-host-macos/src/runtime.rs. Reuse existing fixture, request/cancellation, effect and cleanup test seams; every new hook and diagnostic must compile out of non-test builds. Pause only after the RuntimeControl action_guard has naturally dropped and the existing post-action cancellation check has run unchanged. Never block inside the StreamingStarted arm while holding RuntimeControl, move or suppress the post-action cancellation check, or introduce a second control boundary. Failure-safe teardown must release every held coordination channel on prerequisite or assertion failure and reconcile the authenticated owned child before fixture-directory removal. The real scripted runtime completes initialize/account/thread/turn protocol and then blocks on stdin with normal TERM exit. Invoke exact cancel_request, then use the existing cancellation cutoff and bounded yield to observe child_exited_without_reaping on its real process identity returning Ok(true), without reaping it. Observe retained identity Current versus the actual other closed state, actual child-enumeration Ok/Err, and final state/reason/cleanup as closed scalars only. Never alter the owned process inventory or substitute an identity. After these real preconditions, the diagnostic asserts the accepted Cancelled outcome; a contradictory terminal assertion is the sought RED, not a preselected cause. Localize the accepted-cancellation-to-process-refresh and terminal-settlement boundary through the actual scripted runtime, real process exit and authenticated current identities. The refresh boundary is a hypothesis to test, not an accepted cause. Do not replace unavailable, reused or current identity observations with fabricated classifications to stand in for the live failure; do not stub successful cleanup, directly compose a terminal state, change assertions to the observed failure, or use a helper-only model as the regression oracle. Preserve the actual production protocol, control flow, process observation, cancellation precedence, signaling, cleanup and terminal projection unchanged. Use deterministic channels and the established bounded-yield pattern within existing guards; no sleeps, budget increase, hidden retry or suite serialization. Before changing any productive behavior, establish an assertion-failing deterministic RED through the real owner, distinguish prerequisite/setup failures from that RED, capture only closed scalar diagnostic categories, and identify the precise owning branch with its synchronization and process-absence evidence. No raw task/protocol content, paths, process identifiers, credentials, endpoints or native object dumps may enter logs or retained evidence. Unique synthetic private fixtures must retain authenticated ownership and failure-safe teardown with no unrelated process or provider/network effect. The only execution command added by this diagnosis is cargo +1.92.0 test --locked --manifest-path native/Cargo.toml -p keiko-host-macos a188_real_cancelled_exit_before_ownership_refresh_diagnostic -- --nocapture. Permit at most twenty explicit focused diagnostic attempts, with no concurrent host test; retain every attempt and exact outcome, and treat a zero-match command as failure. Stop this hypothesis immediately when a genuine owner-branch RED is obtained, on an unmet physical/test prerequisite, or after twenty attempts without RED. Do not change the expected outcome or implement a fix to force a result. This diagnostic cap does not reinstate the waived general orchestration repair-attempt ceiling. Read-only source analysis and independent read-first review may accompany these focused diagnostic tests. Stop this phase after a deterministic RED and owning-branch explanation, or if the accepted seam cannot reproduce the finding without broader scope; retain the diagnostic patch and evidence, then obtain a new successful semantic readiness contract before any productive fix, further qualification or delivery. No other tracked file, existing test assertion, production-compiled byte, shared non-test helper, driver, frontend, dependency, schema, coverage policy, package policy or permission boundary may change. Do not update the six qualification identity constants yet, stage or commit a diagnostic candidate, run physical/canonical acceptance again, publish, change PR state, resolve reviews or merge under V85. Diagnostic execution has zero qualification credit. The separate earlier provider-crash failure remains unresolved and is not claimed fixed or explained by this cancellation investigation. Preserve all V83 single-display physical scope, current-source/package/readiness binding, unique window and stable topology, actual Unicode/IME and visual observations, fresh user-confirmed one-count VoiceOver, three consecutive canonical cancellation tranches, full local/platform/remote gates, zero-effect/descendant/residue, audit and restoration obligations for a later accepted corrective delivery. External/multi-display coverage remains unverified unless actually observed. Unlimited orchestration attempts do not waive diagnosis, retained failed evidence or semantic revalidation. Defect: Preserve fail-closed startup recovery ownership #213 remains blocked until actual Defect: Complete turn cancellation within the 5 s terminal bound #188 integration, Integrated packaged macOS acceptance for the Codex tracer #104 owns final integrated acceptance, the inactive guarded merge operation remains unavailable, and dev remains human-only.

• Historical V84 (execution superseded by V85) deterministic reader-retirement fixture repair: Under the operator's explicit autonomous epic-quality repair authority, freeze signed clean bd428230126e5a2b381eb395b0e515d57bcc9d25, tree 7a27194b7eca14e4d4ce8fa8251d3a5d4c38880f. V83 display-policy implementation, focused 66/66 tests and independent architecture/security source audits passed; the complete local quality run did not pass, stopping at native coverage with provider_crash_is_terminal_and_retry_repeats_fresh_preflight. Twenty isolated instrumented attempts, twenty-two full instrumented workspace attempts and one diagnostic immutable-snapshot coverage run passed; full attempt 23 failed the distinct a151_owned_cleanup_workers_cover_success_failure_and_retention assertion at retained-reader reconciliation. The original provider-crash case passed that attempt and remains an unresolved diagnostic item, not explained or fixed by this repair. Independent read-first diagnosis confirms the a151 fixture sends its retired notification before worker return, whereas the production reconciler correctly requires actual JoinHandle completion. The prior panic-reader row must also be independently proven retired so contamination cannot be mistaken for this interleaving. Matching parent v174/child v84/consumer v87 supersede prior execution write allowlists only to authorize the existing a151_owned_cleanup_workers_cover_success_failure_and_retention test inside native/crates/keiko-host-macos/src/runtime.rs and the six readiness version/fingerprint constants plus matching identity assertions in quality/codex-tracer-acceptance.mjs and quality/codex-tracer-acceptance.test.mjs. No productive Rust byte, other Rust test, shared helper, driver, dependency, frontend byte, display validator or coverage exclusion may change. Demonstrate the old invalid completion assumption failure-first using a deterministic channel-held reader after notification. Then assert that this unfinished reader remains retained, release it, wait within the existing one-second test guard for actual JoinHandle completion using the established bounded-yield pattern, and require successful production reconciliation plus an empty retained queue. Prove the preceding panic row left no retained reader. Keep failure-safe release/teardown; do not add sleeps, inflate a budget, weaken an assertion, replace production reconciliation with a stub, fabricate completion, or serialize the suite. All V83 single-display scope, physical observation, identity, topology, timing, authority, redaction, package, no-effect and cleanup requirements remain unchanged. Run the complete focused fixture test, full affected instrumented host/workspace tests, existing coverage floors and independent read-first audits before one additive signed noreply successor. Then repeat the whole clean-head Native quality, high audit and packaged macOS acceptance, followed by fresh real physical observations including user-confirmed exactly one VoiceOver terminal announcement, three consecutive exact-head canonical cancellation tranches, final findings-zero audit, normal non-force PR Fix #188 cancellation terminal bound #211 publication and fresh exact-head remote/Codex review settlement. Retain the failed run and all diagnostic attempts; diagnostic passes are not qualifying evidence. Continue investigating the original provider-crash failure with exact assertion capture and do not claim it fixed by this fixture change. Any confirmed corrective source change outside this test/identity slice requires another successful semantic readiness validation. External/multi-display coverage remains explicitly unverified unless actually observed. Restore temporary settings. Unlimited repair attempts do not waive diagnosis or replanning. Defect: Preserve fail-closed startup recovery ownership #213 follows actual Defect: Complete turn cancellation within the 5 s terminal bound #188 integration and Integrated packaged macOS acceptance for the Codex tracer #104 owns final integrated acceptance; inactive guarded merge remains unavailable and dev remains human-only.

• Historical V83 physical display scope (repair execution superseded by V84): The operator explicitly requests completing this epic without an external monitor. This is a semantic reference-environment scope amendment, not a claim that external or multi-display testing passed. CQS permits a justified issue-specific quality envelope; ADR-0006/ADR-0013 and the Native design baseline require genuine physical macOS, VoiceOver, visual, scaling and IME evidence but no external monitor count. Freeze signed clean 7c65d72ca4d8bb4ae8af1daee1a6d0f3848629b5, tree 04ec5699e5b7813a7d41b5f22bda1f3de5eceeb8, with its full local quality, high audit and packaged macOS acceptance green and independent source audits zero. Those results remain historical exact-head evidence, not qualification for a successor. Matching parent v173/child v83/consumer v86 supersede all earlier external-only/multi-display physical requirements and execution write allowlists solely as follows. Authorize only quality/codex-tracer-acceptance.mjs, quality/codex-tracer-acceptance-io.mjs and their existing .test.mjs files to adopt one shared closed physical-display validation policy and bind exactly the six current readiness version/fingerprint constants. Physical observation may target one active internal or external display within an actual nonempty topology of 1 through 16 displays. Internal and external counts are nonnegative safe integers whose sum equals active count; the observed target class must have a positive corresponding count; exactly one semantic Keiko window must match exactly one display. Reject absent, extra, malformed, noninteger, negative, excessive, contradictory or unsupported class/count/binding fields. Preserve current exact object field closure, structural full-v3/physical-v2 formats, fresh source/package/readiness binding, and rejection of stale records. The criterion change is explicitly bound to these new contracts rather than silently reinterpreting older evidence. Keep all existing active-display normalization, ephemeral same-window/display-position proof, no-movement and stable-topology checks, and equal automated/reference/physical aggregate topology; no identifiers or geometry may persist. Add failure-first real-validator tests for single internal and single external physical observations and full evidence, valid mixed/multiple topologies, class-not-present and all malformed/boundary/stale/extra-field cases. A valid old external/multi-display shape remains accepted when genuinely observed; no fixture is physical proof. Preserve every product/runtime/frontend byte, driver, dependency, permission boundary, hardware/OS/power/thermal requirement, timing budget, coverage floor/exclusion, package policy, redaction and no-effect/cleanup requirement. No fake display, synthetic observation, blanket skip, runtime login automation or credential read. Run the complete affected acceptance/IO tests and coverage, formatting and independent read-first audit before one additive signed noreply successor. Then run the whole clean-head Native quality, high audit and packaged macOS acceptance; collect fresh real physical observations including user-confirmed exactly one VoiceOver terminal announcement; run three consecutive exact-head cancellation tranches through unchanged npm run acceptance:codex-tracer:macos, retaining every valid record; obtain final findings-zero independent audit before normal non-force PR Fix #188 cancellation terminal bound #211 publication and fresh exact-head remote gates/Codex review settlement. Record the actually observed display class/count and explicitly disclose external/multi-display coverage as unverified when not exercised, in the evidence handoff and final epic PR. Do not claim unchanged display coverage or universality from a single-display run. Restore temporary settings. Unlimited orchestration repair attempts remain allowed, but failures require diagnosis and semantic changes require revalidation; no hidden retries or selective disposal. Defect: Preserve fail-closed startup recovery ownership #213 follows actual Defect: Complete turn cancellation within the 5 s terminal bound #188 integration, then Integrated packaged macOS acceptance for the Codex tracer #104 owns final integrated acceptance. Inactive guarded merge policy remains unavailable and dev remains human-only.

• Historical V82 terminal correction (execution superseded by V83): Freeze signed 7d5b91c8ab5bf46f15f528f19aa82d85d1b1af25, tree dda61dd4f515ac36d41202bdb215dca6be594da4, parent dd1c8c1e7a1b6132f8525cbd828381d2b733853b. Retain V80 production ownership corrections and V81 deterministic Rust coverage additions without reimplementation. V81 precommit focused 9/9, Host 425/425 and full-workspace coverage diagnostic passed (1986/2322 branches, 85.5297157623 percent); these are not complete clean-head qualification. Its whole quality run was deliberately interrupted on the final frontend audit finding after installation, toolchain, repository contract and Markdown passed; no physical/canonical evidence or push followed. Confirmed owning defect: after an invalid or missing first channel view, a valid exact authoritative non-completed terminal is rejected because latest is null; rejected, malformed, unavailable, or still-pending cancellation acknowledgement must not erase independent final-response authority. A shape-valid first preflight with foreign task/run IDs can also seed latest and make a final with a correct outer request ID but wrong nested IDs appear current. The accepted response remains authoritative under retained V29 and AC2/AC4, while content never creates identity or cancellation authority. Matching parent v172/child v82/consumer v85 supersede earlier execution allowlists for this correction: permit only native/frontend/src/port.ts at the common request-owned channel/final validation and terminal-supervision owner; deterministic regressions in native/frontend/src/port.test.ts and native/frontend/src/main.test.ts; and exactly six readiness constants in quality/codex-tracer-acceptance.mjs with corresponding assertions/stale-pair fixtures in quality/codex-tracer-acceptance.test.mjs. All Rust, main.ts, other tracked paths, dependencies, schemas, drivers, hooks, product timeouts, thresholds, coverage exclusions, credentials and historical commits are frozen. Use one locally derived canonical request/task/run/workspace identity predicate for every channel and final view; do not let a first channel frame create a replacement identity. Authoritative finals alone may use the existing locally derived preflight seed when no valid progress exists. Preserve envelope, identity, evidence, text-prefix, quarantine, reason, progression and terminal checks. A valid canonical non-completed final must settle independently of a failed or pending separate cancellation acknowledgement; provisional channel terminal views remain non-authoritative. Retain the completion-versus-accepted-cancellation fence, reject completed from preflight, never infer an accepted acknowledgement or fabricate stopping/cancelled/cleaned, and ignore all late events, acknowledgements and responses after the once-only terminal. Preserve exact-request recovery and retry for unresolved cleanup. Before productive edits, capture failure-first tests through the existing real port and UI composition seams with fake clocks and controlled promises. Cover invalid/lost first progress; no abort and user abort; accepted/rejected/malformed/rejected-promise/unresolved acknowledgement; final-before and final-after acknowledgement; truthful cancelled/cleanup-failed/containment-failed/timed-out/failed outcomes; wrong outer request, task, run, workspace and mixed identities; poisoned first preflight; malformed/error envelopes; early completed and provisional success; valid prior progress continuity; inclusive existing watchdog boundary, late settlement and safe next-turn recovery. Run focused regressions, full frontend tests and coverage, typecheck, format, identity tests and independent read-first audit before one additive signed noreply successor. Then require the entire clean-head Native quality, high audit, macOS package acceptance, fresh physical observations, three consecutive exact-head cancellation tranches using the unchanged canonical command, and final independent findings-zero audit before normal non-force publication to PR Fix #188 cancellation terminal bound #211 and fresh exact-head gates/Codex review settlement. Preserve 100 ms stopping, 4500 ms watchdog reserve, inclusive 5000 ms outer bound, no-effect authority, privacy/redaction, package/display requirements, human-confirmed VoiceOver one-count evidence and restoration of temporary settings. The operator explicitly removes the orchestration repair-attempt count ceiling for this task; every failure still requires diagnosis, semantic changes still require revalidation, and hidden retries or selective disposal of acceptance failures remain prohibited. Defect: Retain cancellation supervision after invalid channel input #212 remains superseded provenance, Defect: Preserve fail-closed startup recovery ownership #213 follows actual Defect: Complete turn cancellation within the 5 s terminal bound #188 integration, and Integrated packaged macOS acceptance for the Codex tracer #104 owns final integrated acceptance. Inactive protected merge policy still forbids agent merging; dev remains human-only.

• Historical V81 coverage correction (execution superseded by V82): Freeze signed clean dd1c8c1e7a1b6132f8525cbd828381d2b733853b, tree 3951aa31840118a1f7fa16cdd00b60033b62bdde, parent f9b241ce83bc6c9cb6a51b816fe820579749a484. V80's five owning product corrections and independent findings-zero read reviews are retained, not reimplemented. Its complete clean-head quality attempt failed native branch coverage below 85 percent after control, format, lint, architecture, build, and frontend coverage passed; later qualification, physical/canonical evidence, and push did not occur. The separate unchanged-head diagnostic measured 1956/2300 branches (85.043478 percent), only one covered outcome above the floor; it is diagnosis, never a successful retry or qualification credit, and the discarded failed-run report cannot identify which outcome differed. Matching parent v171/child v81/consumer v84 authorize only meaningful deterministic test additions or fixture correction inside the existing runtime.rs test module, native/crates/keiko-host-macos/src/tauri_adapter_tests.rs, tests.rs, and adapter_tests.rs; plus exact readiness rebinding in quality/codex-tracer-acceptance.mjs and its test. No productive Rust or frontend behavior, other tracked path, gate, exclusion, threshold, schema, dependency, test driver, production hook, timeout, credential, or historical commit may change. Cover report-identified owning branches through existing clocks, synchronization, actual accepted Host requests, and owned process fixtures: current/stale document retirement and retained runtime cancellation records; invalid or retired admission authority including final reservation revalidation; duplicate and capacity-bound deferred Host failures without a later-owner effect; queued stopping, cancellation-winning dequeued projection, and preservation of genuine worker cleanup failure. Add relevant malformed, empty, boundary, poisoned, unavailable, stale, and recovery variants without padding, assertion-free execution, fabricated cleanup, or sleep-based oracles. The failed complete coverage gate is the failure-first quality evidence; new behavioral assertions must exercise the real owner without changing expected product semantics. Run complete focused Host tests and the unchanged full-workspace nightly branch-coverage diagnostic after actual test changes; no unchanged rerun may recover credit. Require every existing 85-percent native metric before committing; retain actual counts and evidence rather than depending on the one-outcome margin. Any unexpected behavioral failure or required production change stops for diagnosis and a newly validated scope. After focused green and findings-zero read-first review, create one additive signed GitHub-noreply successor with exact v171/v81/v84 bindings, then run the whole clean-head Native quality, high audit, macOS package acceptance, fresh physical evidence, and three consecutive exact-head cancellation tranches using the existing canonical command, retaining every valid record. Preserve all V80 acceptance obligations: exactly-once truthful stopping/terminal, 100 ms stopping, 4500 ms watchdog reserve, inclusive 5000 ms outer bound, no-effect authority, privacy/redaction, unchanged package/display policy, fresh human-confirmed VoiceOver one-count evidence, restored temporary settings, final independent findings-zero audit, normal non-force PR Fix #188 cancellation terminal bound #211 publication, and fresh exact-head gates/Codex review settlement. Defect: Retain cancellation supervision after invalid channel input #212 remains superseded provenance inside Defect: Complete turn cancellation within the 5 s terminal bound #188; Defect: Preserve fail-closed startup recovery ownership #213 owns startup recovery only after Defect: Complete turn cancellation within the 5 s terminal bound #188 integrates; Integrated packaged macOS acceptance for the Codex tracer #104 owns final integrated acceptance. No agent merge while protected policy is inactive.

• Historical V80 candidate correction (execution superseded by V81): Supersede unexecuted draft v79 after the requested Codex review. Freeze signed clean f9b241ce83bc6c9cb6a51b816fe820579749a484; prior local/macOS greens are provenance and physical/canonical completion remains absent. Confirmed defects are (A) queued pre-cancel streaming/delta/quarantine applied after Stopping creates false containment; (B) poisoned Host renderer-loss/shutdown/channel paths erase typed failure into empty successful records; (C) Host failure after accepted preflight but before Runtime reservation is lost while no Runtime owner exists; (D) deferred terminal/nonterminal channel-failure cleanup can revoke a replacement renderer because originating generation/document identity is absent; (E) invalid channel or rejected/malformed/invalid final response without prior user abort prematurely removes supervision, retry, and accessible terminal state. E includes draft Defect: Retain cancellation supervision after invalid channel input #212 and Codex's provisional-terminal failure report and must be fixed once at the common owner, not split into a cyclic prerequisite. Matching parent v170/child v80/consumer v83 authorize only these owning corrections and deterministic regressions in existing native/crates/keiko-host-macos/src/runtime.rs, turn.rs, lib.rs, tests.rs, request_adapter.rs, adapter_tests.rs, tauri_adapter.rs, tauri_adapter_tests.rs; native/frontend/src/port.ts, port.test.ts, main.ts, main.test.ts; and exact readiness rebinding in quality/codex-tracer-acceptance.mjs and its test. No other tracked path or public schema changes. A must reject cancellation-winning queued projection while retaining worker outcome/cleanup and exactly one truthful stopping/terminal; separate owned state mutation from external callbacks when fencing projection. B must retain typed immediate closed failure and reentrancy-safe deferred failure identity/cleanup, not preserve a future cancellation window or signal a later owner. C must atomically revalidate exact accepted Host authority with Runtime reservation under Runtime-before-Host order, including turn and readiness; do not install permanent idle poison onto unrelated healthy requests. D must capture the originating sender generation/document and atomically reject stale failure retirement while retaining original-operation cleanup. E must use one bounded identity-preserving supervision/settlement path for invalid events, conflicting provisional terminals, and failed final responses with or without prior abort; reject invalid data, retain same-run retry until acknowledged cancellation or truthful cleanup-unverified containment, announce one stable polite atomic failure terminal, preserve applicable answer text, ignore late settlement, and block fresh execution until cleanup recovery is proven. Never promote provisional channel success into authoritative success. Preserve the existing 4500 ms watchdog reserve, inclusive 5000 ms outer bound, 100 ms stopping bound, runtime version, no-effect authority, redaction, package/display/privacy policies, thresholds, and merge boundary. Use deterministic real-owner REDs for all five paths plus held-fence reentrancy, queued/dequeued races, all cancellation sources, absent/prior cancellation, healthy/poisoned controls, old/new renderer, unavailable acknowledgements, and cleanup/recovery. Expected named regression REDs authorize only these fixes; unexpected failure stops for diagnosis/replanning. Reuse existing private test mechanisms; no new driver, production hook, timeout, hidden retry, sleep oracle, coverage exclusion, dependency, credential access, or historical rewrite. After focused GREEN and read-first review, create one additive signed GitHub-noreply successor; run complete clean-head Native quality/high audit/macOS acceptance with pinned toolchains; collect fresh physical evidence and three consecutive exact-head cancellation tranches using the existing canonical command (one invocation is one sample), retaining each valid record; then findings-zero independent audit, normal fast-forward push to PR Fix #188 cancellation terminal bound #211 source, fresh exact-head gates/Codex review, and evidence-backed review settlement. Restore task-specific settings and require fresh user-confirmed VoiceOver one-count evidence. Defect: Retain cancellation supervision after invalid channel input #212 is consolidated provenance without separate implementation; Defect: Preserve fail-closed startup recovery ownership #213 alone owns preexisting startup recovery after this delivery; Integrated packaged macOS acceptance for the Codex tracer #104 alone owns final full integration. No agent merge while protected policy is inactive.

• V75 Native direct-verification correction: Freeze exact signed clean e8b95563e1c2bdaeb96351e9c17f9f92172f4910, parent b84848fc45b7d3f43fb55fd87859b8f0c8e7cc56, tree b59008f4c5a9f5c1ae62e607fdceb8975a75a032, good signature and GitHub-noreply identity. V74 focused identity verification passed 1/1 under Node 24.18.0/npm 11.16.0. The subsequent generic-skill wrapper invocation failed immediately because .keiko-scripts/verify-receipt.sh is absent from this Native repository; it ran no gate and earns zero credit. Matching parent v165/child v75/consumer v78 authorize only the two-file readiness rebind in one signed noreply successor, then the repository-owned direct Native sequence npm ci --ignore-scripts, npm run quality, npm audit --audit-level=high, one npm run acceptance:macos, fresh physical/canonical evidence, audit, and remote delivery, all with literal cached Node 24.18/npm 11.16 PATH. No wrapper invention, runtime/product/UI, budget, schema, privacy, target, graph, retry-as-success, or merge change. Any failure requires replanning.

• V74 explicit-toolchain-PATH correction: Freeze signed clean base b84848fc45b7d3f43fb55fd87859b8f0c8e7cc56 and exact two-file identity diff SHA-256 e94788a73c921bf97fd8c3128ec4a76b30213c04b398c8ba2d000dadb30d8a48, +12/-12. The v73 command again stopped before tests because the operator verified but did not prepend the accepted cache bin, so ambient Node 25.9/npm 11.12.1 ran; zero credit, no rerun. Matching parent v164/child v74/consumer v77 authorize rebinding only those two identity files and one focused verification with a literal environment PATH beginning at the authenticated cached node-v24.18.0-darwin-arm64/bin; it must print Node v24.18.0 and npm 11.16.0 before tests. On green, create one signed noreply commit and continue the unchanged full one-shot qualification. No install, network, further source, runtime/product/UI, budget, schema, privacy, target, graph, retry-as-success, or merge change. Any failure requires replanning.

• V73 pinned-npm preflight correction: Freeze signed clean base b84848fc45b7d3f43fb55fd87859b8f0c8e7cc56 and exact uncommitted two-file identity diff SHA-256 a1b87af5c857bd1e6e76447c7e5787bbd631f9f2f1404cd3a9edbac5f505e072, +12/-12. The first v72 focused command stopped before tests because ambient npm 11.12.1 violated repository-required 11.16.0; it earns zero credit and is never rerun. Matching parent v163/child v73/consumer v76 authorize the same identity-only implementation and qualification scope, using the already-cached npm 11.16.0 CLI with Node 24.18.x for all npm commands. No additional source change, network installation, runtime/product/UI, budget, schema, privacy, target, graph, retry-as-success, or merge change. Any subsequent failure requires semantic replanning.

• V72 exact-head qualification correction: Freeze unchanged signed clean b84848fc45b7d3f43fb55fd87859b8f0c8e7cc56 and the consumed v71 host-only diagnostic, which completed all 402 host tests in 15.47 seconds with zero failures and earns no gate or acceptance credit. The result supports the existing readiness-handshake fixture correction but cannot convert the earlier failed macOS acceptance attempt into success. Authorize only exact parent v162/child v72/consumer v75 readiness identity rebinding in quality/codex-tracer-acceptance.mjs and quality/codex-tracer-acceptance.test.mjs; one signed GitHub-noreply additive successor atop b84848fc; focused identity verification; complete clean-head quality, high npm audit, and one fresh macOS acceptance attempt; fresh exact-head package, multi-display physical, VoiceOver, and canonical evidence; findings-zero mandatory audit; and normal fast-forward push to the existing PR Fix #188 cancellation terminal bound #211 source ref. No runtime/product/UI/helper/retry/sleep/budget/threshold/exclusion/schema/package-policy/display-scope/credential/privacy/target/graph/merge-boundary change. Stop and semantically replan on any failure or drift; no failed or diagnostic run earns release credit and no rerun is treated as success.

• V71 host-only diagnostic correction: Freeze unchanged signed clean head b84848fc45b7d3f43fb55fd87859b8f0c8e7cc56 and consumed v70 diagnostic. The exact v70 workspace command never started a test: desktop test compilation failed because local native/frontend/dist was absent, while the original acceptance attempt had built that directory inside its clean snapshot before the same Rust plan. This is diagnostic-harness failure with zero implementation, gate, or acceptance credit and no tracked change. V71 permits exactly one unchanged-head host-package diagnostic using stable 1.92.0, a fresh derived target directory, accepted source-revision/remap environment, and cargo +1.92.0 test --locked --manifest-path native/Cargo.toml -p keiko-host-macos -- --nocapture. It may record only bounded test name/state/assertion facts and receives zero gate credit regardless of outcome. No frontend build, workspace/desktop compile, tracked source/index/commit, PR, package, physical/canonical, audit, push, or merge effect is authorized. Stop and semantically replan after the command. Preserve every product byte/budget, cleanup truth, threshold/exclusion, schema, credential/privacy, target, and merge boundary.

• V70 diagnostic-only macOS acceptance host-test stop: Freeze exact signed clean head b84848fc45b7d3f43fb55fd87859b8f0c8e7cc56, parent 17a44085489daa23321cf40168f532c8b1dfbe1d, tree c6f1cccdfd484897162c40fa396215b41f7a01ae, unpushed PR Fix #188 cancellation terminal bound #211 source, and the accepted v69 correction. Focused owner proof passed; complete clean-head npm run quality passed with host 402/402; high audit found zero vulnerabilities. The first npm run acceptance:macos attempt passed frontend tests/build and then failed only the workspace Rust test command with status 101; its sanitized tail names the host test binary but omits the failing test/assertion. No package, physical, canonical, audit, push, or delivery credit follows, and no rerun is authorized. V70 permits exactly one unchanged-head diagnostic command with the stable 1.92.0 toolchain and accepted production remap/source-revision environment: cargo +1.92.0 test --locked --workspace --manifest-path native/Cargo.toml -- --nocapture. Record only bounded test name/state/assertion facts; make no tracked source, index, commit, PR, package, physical/canonical, or merge mutation. The diagnostic receives zero gate/completion credit regardless of result and must be followed by semantic replanning before any edit or qualification. Preserve every product byte/budget, cleanup truth, threshold/exclusion, schema, credential/privacy, target, and merge boundary.

Nothing was pushed; PR Fix #188 cancellation terminal bound #211 remains at 0734f6e3. Mandatory audit produced P0=0, P1=1, P2=0 after one ordinary host run failed cleanup_failure_retains_ownership_until_reconciliation_proves_exit: its shell intends to ignore TERM but cleanup can signal before the child installs the trap, so retained ownership is scheduler-dependent. All v68 green receipts receive zero final credit. Preserve 17a4408 without amend/reset and authorize one additive signed successor changing only that existing cfg(test) fixture to emit and consume a bounded readiness handshake after trap installation and before cleanup, plus exact parent v159/child v69/consumer v72 identity rebinding in the same two acceptance files. No production byte, product deadline, cleanup policy/classification, assertion outcome, retry, sleep, test exclusion/threshold, schema, package/display/VoiceOver, credential/privacy, target, or merge authority change. Require failure-first attribution from the audit, focused owner proof, full clean-head quality, high audit, macOS acceptance, fresh exact-head physical/canonical evidence as required by sourceRevision binding, mandatory findings-zero audit, normal fast-forward push to the existing PR source, and fresh exact-head remote settlement.

Signature verification is good, but author and committer expose a personal Gmail address instead of the established GitHub noreply identity. Nothing was pushed; PR Fix #188 cancellation terminal bound #211 remains exactly at the parent. Preserve the rejected branch/worktree and commit without amend/reset/delete. Authorize a fresh recovery worktree/local branch from exact 0734f6e3; reapply only the same runtime.rs v65 bytes and exact parent v158/child v68/consumer v71 fingerprints in the two identity files; set author and committer to Nikolaos Vasilopoulos using 159039192+Niko4417@users.noreply.github.com; verify the exact three-path diff; create one good signed commit; run the complete clean-head local bar, high audit, macOS acceptance, findings-zero issue audit; and normally fast-forward-push that commit to remote codex/188-cancellation-terminal-v63.

Fresh host 402/402 and identity 14/14 passed. The v66 complete attempt passed quality control and 92.52% line / 88.04% branch / 92.85% function coverage, then stopped only at native format. Read-only inspection of captureRepository proves native snapshots reject any porcelain status and materialize only the committed HEAD tree, so a clean signed successor is a precondition to every native gate. Authorize only exact v157/v67/v70 readiness rebinding in the two identity files; cached-diff verification and read-first review; one additive signed commit on the existing branch; then complete npm run quality, high npm audit, acceptance:macos, mandatory findings-zero audit, and exact-head remote/PR settlement.

Focused host 402/402 and identity 14/14 passed. The complete v65 quality attempt passed the control plane and aggregate 92.52% line / 88.04% branch / 92.85% function coverage, then stopped solely at native format because the patch was unstaged and the immutable snapshot rejected repository state. This is zero complete-gate credit. Authorize only exact parent v156/child v66/consumer v69 fingerprint/version rebinding in the two identity files, resulting mechanical diff-hash drift, staging exactly these three authorized paths, and one fresh focused/full local, audit, signed-successor, and remote sequence from the staged immutable snapshot.

One uninterrupted canonical sequence passed pinned install, complete quality, high dependency audit, and macOS acceptance; only final Codex-tracer acceptance rejected with zero gate credit. Bounded in-memory diagnostics that changed no repository byte proved permission denial now passes at 1,093 ms overall / 53 ms local and successful selection at 379/33 ms, then isolated cancel-turn at 228 ms overall / 102 ms local followed by a passed cancelled terminal 185 ms later. Exact source proof shows quality/codex-tracer-accessibility-source.mjs samples projectionStartedAt immediately before synchronous Press(application, CFSTR("Codex-Lauf abbrechen")); WaitForProjection therefore includes native AX press latency in the unchanged 100 ms local window. V59 authorizes exactly: add one hermetic failure-first owning-source regression in quality/codex-tracer-accessibility-source.test.mjs modeling a 140 ms synchronous cancel press followed by immediately visible stopping and proving the current pre-action clock exceeds the local bound; in quality/codex-tracer-accessibility-source.mjs, move only the cancellation projection clock sample to immediately after the synchronous press returns, while the existing outer adapter action and terminal clocks retain the inclusive 5,000 ms envelope; update only numeric parent/child/consumer versions and exact matching fingerprints in quality/codex-tracer-acceptance.mjs and quality/codex-tracer-acceptance.test.mjs; run focused RED/GREEN, generated Objective-C compilation, complete pinned qualification, fresh findings-zero four-role audit, and one additive signed private-email commit; then obtain fresh exact-head physical evidence and run one new uninterrupted canonical sequence before push or replacement PR.

The exact packaged application and fresh external-two-display physical observation passed cancellation at 51 ms with one terminal announcement and zero residue. One uninterrupted canonical sequence then passed pinned install, complete quality, high dependency audit, and macOS acceptance; only final Codex-tracer evidence validation failed. Bounded redacted instrumentation identified only budget-localProjectionP95Ms and budget-local-projection-measurements: permission-denied workspace selection measured 133 ms, successful selection 37 ms, and cancellation 51 ms. Exact source proof shows the denied path starts projectionStartedAt before synchronous native PressPickerControl, while the successful path uses PressPickerControlWithProjectionTiming and starts its local projection clock after the native action returns. The denied path therefore asymmetrically charges native picker and AX action time to the unchanged 100 ms local-projection budget. V58 authorizes exactly: add a hermetic failure-first owning-source regression in quality/codex-tracer-accessibility-source.test.mjs proving a 140 ms native denial action plus immediate local projection is accepted without changing the 5,000 ms overall action limit; in quality/codex-tracer-accessibility-source.mjs, route permission-denial confirmation through the existing projection-timing helper so its local clock begins at native action return while total elapsed time retains the existing inclusive 5,000 ms bound; update only numeric parent/child/consumer versions and exact matching fingerprints in quality/codex-tracer-acceptance.mjs and quality/codex-tracer-acceptance.test.mjs; run focused RED/GREEN, complete pinned qualification, findings-zero four-role audit, and one additive signed private-email commit; then obtain fresh exact-head physical evidence and run one new uninterrupted canonical sequence before push or replacement PR. Exact v58 write scope is those four quality files. Never increase the 100 ms or 5,000 ms budgets, add retries or sleeps, change native/frontend/product/runtime/picker/display/credential/privacy behavior, emit a new evidence field, synthesize evidence, credit a failed or diagnostic run, push before green, or merge outside epic/98-codex-tracer.

A bounded instrumented reproduction exposed packaged-journey-measurement-invalid; a separate action trace using the repository-owned Documents fixture passed workspace permission denial at 1,137 ms total and 139 ms projection, disproving picker behavior as owner. Exact source tracing proves quality/codex-tracer-accessibility.mjs samples cancellationStartedAt before synchronous adapter launch, but quality/codex-tracer-accessibility-source.mjs starts the accepted action clock immediately before cancellation AX press and returns truthful action-to-stopping projectedMs; assigning the outer duration to stoppingElapsedMs wrongly charges adapter startup, AX discovery, and serialization to the unchanged 100 ms product projection budget. V57 authorizes exactly: (1) add a hermetic failure-first test in quality/codex-tracer-accessibility.test.mjs where outer adapter invocation advances 250 ms, the validated cancellation projection is 80 ms, terminal progression is 10 ms, and the journey must succeed with turnCancellationProjectionMs=80 and turnCancellationTerminal.stoppingElapsedMs=80; (2) in quality/codex-tracer-accessibility.mjs, derive stoppingElapsedMs only from the already-validated turnCancellationProjectionMs, while retaining the current outer clock as a conservative inclusive 5,000 ms terminal envelope and preserving all temporal-order, containment, cleanup, display-binding, and evidence validation; (3) update only numeric parent/child/consumer versions and matching fingerprints in quality/codex-tracer-acceptance.mjs and its existing test; (4) run focused RED/GREEN, complete pinned qualification, and findings-zero four-role audit, then one additive signed/private-email commit; (5) provision only the existing exact private runtime/profile contract, obtain a fresh exact-head external-two-display physical-v2 observation including real cancellation, crash recovery, VoiceOver one-count user confirmation, visual modes, Unicode/IME, scaling, and zero residue, then run one new uninterrupted canonical sequence from the beginning before push or replacement PR. Exact allowed paths are the four named quality files. Never increase 100 ms or 5,000 ms, change native/frontend/product/runtime/picker/display/credential/privacy behavior, introduce retry or sleep semantics, synthesize evidence, credit the failed or diagnostic runs, touch unrelated generated provider cache, push before green, or merge outside epic/98-codex-tracer.

• V53 APFS-impossible-direction and exact-turn-assertion correction: Freeze signed head 483518217b4d5eed34adbbe7285db50441f67618 and stopped partial v52 overlay SHA-256 33dc0555d5c61c1adae69724b2eac617e4f923ffadee649117c91997949612cb, five paths +1750/-12, empty index/no untracked. The first focused B71 run was 16 pass/2 fail. The standalone 4678:F fixture fails at fs::create_dir with macOS EILSEQ because APFS rejects its invalid-UTF8 component before orphan recovery; reaching that direction would require a prohibited filesystem/read_dir seam, unsafe fabricated DirEntry, or non-authoritative filesystem. The turn.rs 327:T construction does execute its target: refresh changes Runtime accepted cancellation from none to exact while Host acceptance stays none, then owning publication intentionally emits containment-failed/protocol-rejected with cleanup complete; only the test's cancelled-state assertion is wrong. V53 authorizes exactly: delete the separable invalid-UTF8 test and exclude 4678:F; replace only the turn test's cancelled-state substring assertion with containment-failed while retaining cleanupComplete=true, which distinguishes 327:T from the false fallback's cleanupComplete=false; update exact v143/v53/v56 versions/fingerprints. Preserve every other v52 B70 case and R4/W4 repair byte unless a gate/audit requires an owning correction. Same five paths, no seam/non-test behavior, fabricated entry, new path, decision-bearing test flow, scheduler/deadline oracle, gate/tool/threshold/exclusion/denominator/package/display/accessibility change. Re-run focused/full noncoverage qualification and findings-zero four-role audit before one additive signed commit; aggregate coverage only on the signed successor, followed by the complete canonical sequence with no retry-as-success.

• V52 findings-driven deterministic B71 correction: Freeze signed head 483518217b4d5eed34adbbe7285db50441f67618 and rejected unstaged v51 overlay SHA-256 99412b423dd7584b5f74362daff3f8d35dc575aea00c3370834d9e8f87cb78a4, five existing paths +1236/-12, empty index/no untracked path. Its precommit gates were green, but mandatory audit returned correctness P1 and coverage-structure P1: only 52 directions are conservatively deterministic; 23 contracted coordinates are unowned; R4 uses a one-second production cleanup deadline as a semantic selector; W4 receives a message before worker return and therefore cannot prove is_finished. Security/resource and accessibility/display audits were findings-zero. Read-only remediation proves nineteen missed directions reachable with existing state/hooks and five directions impossible under the accepted hermetic/no-new-seam boundary.

  V52 authorizes exactly these nineteen individually invoked branch-free cases: 1279:T seed closed saturated containment with idle/no owner so the first overflow predicate is false and materialization makes the second true; 1327:F/1332:F reserve with exact Host token, fill deferred store, poison control, then commit with retained-in-control true; 2114:T use poisoned non-running exact request-id control then handoff; 2493:F, 2495:F, 2496:F use the existing reader-reconciliation hook after idle, respectively set running/exact request/pending request while paused, release, assert cleanup false, then reset; 2620:T use running plus exact request-id, no pending or Host acceptance, then claim disposition; 2670:F rename the tracked repository under exact active owner/nonzero generation then run Host settlement; 3108:T run valid readiness to completion then replace its work directory with a regular file so final cleanup fails; 3240:T construct an owned turn worker with queued outcome/cleanup false and a blocked worker, await it, then release/join; 3345:F use the existing Directory hook, cancel exact request and remove work root while paused, then release to exact cancelled error; 3722:F use the existing Publish hook plus poisoned process group, accept exact cancellation while paused, then release; 4154:T direct exact request-id/effect-generation-zero control into linearized initialization; 4332:T construct private verified configuration from an opened directory with matching directory identity; 4678:F create an invalid-UTF8 entry with Unix OsStringExt and invoke orphan recovery; 5019:T use existing Spawn hook, accept cancellation while paused with poisoned process group/blocking child, then release and prove direct kill/wait rollback; 5608:F retire a turn worker with cleanup false, blocked worker, and closed deadline, then take/release/join retained ownership; turn.rs 327:T return false from the update callback after deferring exact Host cancellation so acceptance changes only during refresh-after-publication.

  Explicitly exclude and do not chase runtime.rs 1259:T, 3075:T, 4460:F, 5639:F, and turn.rs 140:T: they require respectively post-commit/pre-finalize observation, post-Bind/pre-check observation, a validation-to-owner-write race or permission fault, proof of finished state before transferring an unjoined handle, or a callback after immediate containment cancellation. Repair R4 by taking the retained child from the private vector and performing direct normal kill plus blocking wait before recovery; remove its one-second production reconciliation deadline. Split W4: retain only the blocked-reader construction for 5700:T and delete the finished-worker construction/claim for 5639:F. Retain the other 52 conservatively deterministic directions, yielding B71 and eleven-direction margin over the exact deficit 60. Only the same five paths may change; no new seam, production/non-test behavior, loop, conditional expected result, sleep, polling, scheduler/deadline oracle, permission/resource fault, test/duplicate credit, denominator reduction, gate/tool/threshold/exclusion, package/display/accessibility, or Integrated packaged macOS acceptance for the Codex tracer #104 implementation change. Update exact v142/v52/v55 versions/fingerprints in both existing quality files. Re-run focused/full precommit qualification, authenticate exact scope, and obtain findings-zero four-role re-audit before one additive signed commit; no aggregate coverage until that signed successor, then run the complete canonical sequence from the beginning with no retry-as-success.

Canonical postcommit used exact Node 24.18.0/npm 11.16.0: dependency install, repository contract, Markdown, Prettier, control-plane coverage, bootstrap, native format/lint/architecture/build all passed; control coverage was 92.32% lines, 87.95% branches, 92.72% functions. Native coverage passed frontend 73/73 with 90.25% statements, 90.74% branches, 90.17% functions, 93.70% lines, then stopped only at Rust aggregate branches below 85%. No package/platform/security/signing/native-test/npm-audit or acceptance command ran. Static A151 mapping is insufficient against the actual instrumented build, while the canonical command used --summary-only and persisted no exact counts or regions.

The exact receive-entry EOF/cancel regression is green; twenty of twenty-one final static cases are green; completed-empty, stderr saturation, deadline cleanup, post-action cancellation, initialize-write, publication, cleanup, and readiness-settlement constructions are exact; the RAII regression performs a hook-free valid bind before any fresh hook. One direction remains non-hermetic under v48: the second operand of consecutive initialize and account/read writes in turn and readiness protocol. Both writes are small atomic pipe writes, and no existing hook separates them; closing the reader after the first observed line races the immediate second write. V49 authorizes exactly one fourth private cfg(test) seam: a per-ActiveRuntime, one-shot channel barrier invoked after the initialize write succeeds and immediately before the account/read write, in both run_turn_protocol and run_protocol. The branch-free turn and readiness tests must wait for entry, close the receiver, release the barrier, and assert exact second-write failure and containment/cleanup evidence; timeout is a hang guard only. Preserve the authorized receive-entry, publication, and verified-binary seams and every green v48 case. Correct all readiness identity fields in both quality source/test: numeric parent/child/downstream versions must be exactly 139/49/52 and fingerprints must be the newly accepted v139/v49/v52 values; the partial 135/45/48 numbers are explicitly rejected. No fifth seam, new path, decision-bearing test logic, test-code/duplicate credit, real-time or scheduler semantic oracle, production behavior, public API, schema, dependency, gate, threshold, exclusion, budget, package/display/accessibility boundary, or Integrated packaged macOS acceptance for the Codex tracer #104 implementation change.

After readiness, only new v137/v47/v50 fingerprints and the required hook-free valid bind in the RAII regression landed; the numeric readiness fields remain stale and no twenty-one-direction test landed. Read-only feasibility mapping proves twenty directions reachable without another seam: post-reader write/stderr/deadline/post-action/completed-empty protocol cases through staged pipe closure, explicit read acknowledgements, bounded stderr saturation, production protocol deadline, existing update/control fence, and scripted frames; retained publication failure through the existing post-disposition barrier with active poisoned ownership; cleanup false predicates through exact injected result/join/cutoff; atomic readiness settlement through direct owner state. The final authenticated run_turn_protocol EOF plus cancelled-state direction at current production coordinate 4007 is not scheduler-independently reachable because no observation exists after the loop-top cancellation check and before recv_timeout/EOF classification. V48 authorizes exactly one third private cfg(test) seam: a per-ActiveRuntime, one-shot channel barrier invoked immediately before the owning turn-protocol receiver call, after loop-top cancellation validation. The test must wait for entry, accept exact cancellation, close or resolve the receiver as EOF, release the barrier, and assert the exact cancelled terminal/cleanup result. The barrier is absent from production builds, used by one branch-free test, and its timeout is only a hang guard. Retain all v47 obligations for branch-free synchronized cases covering all twenty-one directions, source/test numeric versions and new exact parent v138/child v48/Integrated packaged macOS acceptance for the Codex tracer #104 v51 fingerprints, and the valid-bind-before-any-replacement RAII teardown proof. No fourth seam, new path, decision-bearing test logic, test-code/duplicate credit, real-time or scheduler semantic oracle, production behavior, public API, schema, dependency, gate, threshold, exclusion, budget, package/display/accessibility boundary, or Integrated packaged macOS acceptance for the Codex tracer #104 implementation change.

Re-audit closes prior wall-clock, scheduler-selected, branchful-test, initial eighteen-case, and hook-implementation findings but returns three exact evidence classes. First, acceptance source/test pair current fingerprints with numeric versions 135/45/48 instead of accepted 136/46/49. Second, the RAII regression installs a new hook before the valid bind and therefore overwrites rather than observes any stale closure. Third, twenty-one authenticated A151 directions remain unexercised, capping honest gain at 130: fourteen post-reader protocol directions in run_turn_protocol and run_protocol at current overlay production coordinates 3862, 3866, 3899, 3902, 3920, 3949, 3990, 4007, 4030, 5168, 5192, 5196, 5205, and 5206; retained publication failure where worker wait_for_idle must be false while exact active ownership remains; cleanup short-circuit false outcomes for cleaned, joined, and completion-deadline predicates; atomic readiness settlement for poisoned cleanup failure, poisoned acceptance extraction, and healthy exact running readiness without acceptance. V47 authorizes only branch-free individually invoked synchronized cases that reach all twenty-one named production directions and preserve the full A151 ledger; timeouts may guard hangs but never select semantics. Correct the three numeric versions to 136/46/49 in source and test while updating exact parent v137/child v47/Integrated packaged macOS acceptance for the Codex tracer #104 v50 fingerprints. Strengthen the existing RAII regression by dropping the early-failure guard and performing the next valid bind before installing any replacement hook, so a stale panic closure would fail the test; a later fresh hook may be tested separately. No third seam, new path, decision-bearing test control flow, test-code/duplicate credit, real-time or scheduler oracle, production behavior, public API, schema, dependency, gate, threshold, exclusion, budget, package/display/accessibility boundary, or Integrated packaged macOS acceptance for the Codex tracer #104 implementation change.

Four unique audit blockers invalidate the overlay: the authenticated A151 ledger proves at least eighteen omissions—handoff_host_cancellation five, claim_turn_request_for_host_settlement_disposition two, turn_request_with_channel three, atomic Host settlement four, publication retained failure one, and cleanup short-circuit conditions three—so current maximum is 133 before other misses; new for, while, match, conditional, conjunction, and disjunction control flow in tests creates instrumented denominator directions that cannot count as production gain; publication, retained-reader, and protocol-reader cases poll wall time or accept scheduler-selected terminal alternatives; the thread-local verified-binary after-open closure lacks teardown on an earlier bind error. V46 authorizes only exact owning correction inside the same nine overlay paths and existing 24-path delivery scope: expand the A151-to-test ledger with individually invoked deterministic cases for all eighteen named omissions and enough authenticated buffer; rewrite every new decision-bearing test table as branch-free explicit calls and assertions so no test or hook direction is claimed; replace every new wall-clock poll and terminal alternative with synchronized channel/barrier completion and one exact state plus cleanup result per case, where timeouts are hang guards only and never choose expected semantics; return an RAII installation guard for the already authorized after-open hook, clear an unconsumed closure on drop, and prove an early bind failure cannot contaminate the next valid bind on the same thread.

Authenticate the sole v44 report at /tmp/keiko-188-v44-ce70d5ea-rust-coverage.json, mode 0600, 4,722,988 bytes, SHA-256 a7f1b99c3d6374b62c6146c85e094778817cb25cb416ba77f2412fc387ed1628: Rust branches are 1,763/2,220 = 79.4144%, so the fixed-denominator 85% deficit is 124. V45 semantically widens verification ownership only: add deterministic table-driven tests and the minimum private test-only injection seams for the authenticated 151-direction A-set, targeting at least 140 honest net new covered directions and aggregate Rust branch coverage at or above 85%. The groups are exact Host-record storage 11; reservation transaction 29; atomic Host settlement 8; cancellation/effect authority 25; publication disposition 4; turn/readiness execution 11; protocol reducers 21; cleanup/workers/filesystem identity 21; Host turn orchestration 7; Host lifecycle/adapters 8; application model/timing 6. The owning functions and exact line/column/direction inventory are bound to report head ce70d5ea and must be posted as planning evidence before editing. Production behavior, non-test control flow, public interfaces, schema, dependencies, thresholds, exclusions, toolchain, package/display/accessibility boundaries, the 100 ms and 5,000 ms budgets, and Integrated packaged macOS acceptance for the Codex tracer #104 implementation remain byte-stable. The only permitted non-test-module bytes are private test-only barriers/hooks compiled exclusively for tests, specifically the publication post-disposition/pre-send barrier and verified-binary after-open identity-replacement hook when their tests require them. Tests must use injected clocks, in-memory frames/writers, synchronized channels or pipes, temporary paths, direct private state, and existing pure reducers. Exclude real network, sleeps, free ports, scheduler-selected results, actual TERM/KILL/reap/proc-list failures, current-PID impossibilities, resource or permission exhaustion, unsafe FFI anomalies, wall-clock loops, compiler/generic duplicates, both-zero regions, and any direction inside test code or test-only hooks from claimed gain. Run focused suites, full Host, workspace Clippy, frontend/evidence/format checks, independent findings-zero audit, one additive signed commit, then the complete canonical postcommit sequence from the beginning. No amend, threshold/exclusion weakening, retry-as-success, twenty-fifth path, push, PR, or merge before all local evidence is green.

• V43 postcommit native-coverage stop and v44 one-shot full Rust report: Freeze exact signed v43 head ce70d5ea96520a3b18ecba1253bde55e7d5116ad, tree 2d17867edb145c393593e2401297d5fdafd77d3c, base diff SHA-256 a62719b51eb1311486d7f3dc653d1c0202604292a15e75fddd9aac1634f911e2, 24 paths +13056/-595, clean worktree, and findings-zero audit. The restarted postcommit sequence passed dependency/toolchain/control-plane/native format-lint-architecture-build gates. Control-plane coverage was 92.32% lines, 87.97% branches, 92.72% functions. Native coverage passed frontend 73/73 and all frontend metrics above 90%, then stopped only because the Rust JSON aggregate reports branches below 85%. No later package/platform/security/signing/native-test/audit/acceptance command ran. The canonical gate captured the Rust summary internally, emitted no exact count, and removed its immutable snapshot/profile, so neither the deficit nor uncovered owners can be recovered read-only. V44 grants one diagnostic effect only: require exact clean signed head/tree and absent /tmp/keiko-188-v44-ce70d5ea-rust-coverage.json; set umask 077, pinned Node/Rust paths and KEIKO_NATIVE_SOURCE_REVISION=ce70d5ea96520a3b18ecba1253bde55e7d5116ad; execute exactly one cargo +nightly-2026-07-17 llvm-cov --locked --workspace --all-features --branch --json --output-path /tmp/keiko-188-v44-ce70d5ea-rust-coverage.json --ignore-filename-regex native/apps/keiko-desktop/src/main.rs --manifest-path native/Cargo.toml; bind before/after head/tree, cargo-llvm-cov 0.8.7 and LLVM version, exit, private mode, bytes, SHA-256, aggregate/per-file counts and uncovered branch regions. The run receives zero gate credit and no retry. Do not edit source/tests/contracts after readiness, commit/amend, alter threshold/exclusion/tool, push, open a PR, or merge. Stop after report authentication and return to semantic planning for a bounded honest branch-gain correction.

• V42 postcommit security stop and v43 scanner-safe marker rename: Freeze exact signed v42 head 3c31b2d8a367d80112330686f1bb5859b6347783, tree 8235d30a61c830090d4d4637cbf033203962aa7f, diff SHA-256 86f5da44efac944e0ca8489c47cf25ecd1c1c1da0b5e733369fdddbf2348ac62, exact 24 paths, clean worktree, base/target 535b0162, and four-role P0/P1/P2 zero audit. Postcommit dependency, toolchain, contract, Markdown, formatting, and numeric coverage passed, then npm run quality stopped because control-plane test closed repository-only security and signing gates pass returned Native source security rejected: source-sensitive-content; later commands did not run. Standard npm test reproduced 833/835 pass, one exact failure/one skip; focused test reproduced deterministically in about 150 ms. Diagnosis found no secret: the new internal identifiers closed_control_failure_token and reconciled_closed_token lexically form token: Option and token = Some or None, which the unchanged credential-assignment regex correctly rejects. An in-memory two-identifier substitution proves Runtime redaction classes change from [credential-assignment] to []. V43 authorizes only mechanical rename to closed_control_failure_marker and reconciled_closed_marker throughout runtime.rs, plus exact parent v133/child v43/Integrated packaged macOS acceptance for the Codex tracer #104 v46 constants in the existing acceptance source/test. Preserve types, values, control flow, poison/settlement semantics, v42 equality fence, all earlier behavior, exact 24-path delivery scope, and every gate/rule. No amend: add one signed successor after failure-first focused security, rustfmt, full Host 298/298, workspace Clippy, affected Node/frontend/evidence checks and findings-zero read-only review; then rerun npm ci --ignore-scripts, npm run quality, npm audit --audit-level=high, npm run acceptance:macos, and npm run acceptance:codex-tracer:macos from the beginning. No scanner exception, suppression, test edit/weakening, new path/schema/budget/display/package/Integrated packaged macOS acceptance for the Codex tracer #104 ownership, credential, or merge-boundary change.

• V41 qualification stop and v42 deterministic terminal-publication result-fence correction: Preserve rejected staged baseline 52be620dd11d45976639d06c4736da13653a6fa21b204dfaa93d85418cf87f8b (24 paths), green unstaged v41 overlay 2839ab1fefada98a7c231f4fda35f65e6e2a336450494446bc0fd1d5c9113997 (11 paths, +313/-37), and combined working-tree SHA-256 36b141ae9b002fac484fd0084c009db1b168f17b15d62272e31c849524d54c70 (the same exact 24 paths, +12999/-594), on base/target 535b0162, stash 903a54a9. V41 writer qualification passed Host 298/298, workspace Clippy, frontend 73/73 plus typecheck, acceptance/IO/accessibility/evidence, and formatting. The independent full Host gate then stopped at 297/298 in terminal_publication_uses_one_clock_at_worker_start_and_completion, exact worker=5000ms, completion=5000ms, expected Skipped, actual Deferred; no rerun or dismissal followed. Read-only diagnosis proves the test releases an already-admitted worker at injected logical time 5,000 ms, then the caller and worker race: the caller may compute zero remaining receive duration and return Deferred before the worker observes equality and sends deterministic Skipped. The clock is ActiveRuntime-local and v41 changed scheduling load only. V42 authorizes only owner-level worker admission/result synchronization so the caller cannot classify timeout before the released admitted worker publishes its exact boundary disposition. Preserve effect start < cutoff, completion <= cutoff, start == cutoff as Skipped, no callback at/after cutoff, bounded real production wait, and every v41 Host/Runtime capacity and AX containment correction. Add a failure-first, hermetic, scheduler-independent +4,999/+5,000/+5,001 regression; no wall-clock sleep, retry, selective-rerun credit, wait-budget change, product semantic change, new path/schema/display/package boundary, or Integrated packaged macOS acceptance for the Codex tracer #104 ownership. Update exact parent v132/child v42/Integrated packaged macOS acceptance for the Codex tracer #104 v45 constants, then run complete qualification, exact-scope authentication, findings-zero audit, signed delivery, and guarded merge only to epic/98-codex-tracer.

• V40 audit stop and v41 Host/Runtime capacity-composition and paired-AX correction: Exact staged v40 candidate 52be620dd11d45976639d06c4736da13653a6fa21b204dfaa93d85418cf87f8b, 24 paths, +12720/-591 histogram, base/target 535b0162, stash 903a54a9, no unstaged/untracked path, passed workspace Clippy, Host 295/295, frontend 73/73 plus typecheck, evidence/accessibility 78/78, and formatting. Mandatory audit returned two unique P1 classes: Host completion can free admission while non-Runtime renderer-loss records remain indefinitely in Runtime storage, allowing a later active exact token to be dropped after two capacity waves; and the paired AX stopping path treats the new internal-failure and cleanup-unverified terminal indices as successful projection evidence instead of containment. V41 adopts the exact candidate only as frozen rejected evidence and authorizes failure-first owning correction within the same 24 paths: bind Host-to-Runtime cancellation-record eligibility at Host acceptance to exact Runtime-owning operations (codex-turn-start and runtime-readiness), keep cancellation terminal authority for every Host request, never forward non-Runtime request IDs into Runtime storage, and require every forwarded Runtime-owned record to be consumed by exact atomic turn/readiness settlement before Host completion frees admission; add two-wave production composition with non-Runtime cancel/complete/reuse and a later active exact renderer-loss token proving literal cutoff plus TERM/KILL, no permanent overflow, and fresh recovery. In the paired AX cancellation path classify provider violation, internal Runtime failure, and cleanup-unverified watchdog terminal indices alike as containment failure, never successful stopping projection, while preserving each exact visible/VoiceOver string and standalone terminal classification. Add source/meta regressions for indices 3/4/5 and update exact parent v131/child v41/Integrated packaged macOS acceptance for the Codex tracer #104 v44 constants. Then fresh complete qualification, exact scope, findings-zero audit, signed delivery, and guarded child merge only to epic/98-codex-tracer. No new path, external schema, 100/5,000 ms budget, display/package boundary, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, credential, or merge-boundary change.

• V39 audit stop and v40 lossless-capacity, settlement-classification, poison-identity, and truthful-terminal correction: Exact staged v39 candidate 810387acfde27ee883159f97533fadb86020a4fcf58ca887319d08ca81f567a8, 24 paths, +12185/-590 histogram, base/target 535b0162, stash 903a54a9, no unstaged/untracked path, passed workspace Clippy, Host 289/289, frontend 72/72 plus typecheck, evidence/accessibility 78/78, and formatting. Mandatory four-role audit returned four unique P1 classes: saturated deferred storage can drop an already accepted active or reentrant cancellation and omit exact TERM/KILL; the deferred-only failed-claim precheck misclassifies a control-retained exact Host cancellation and races settlement; poisoned exact settlement can rotate marker and cancellation identities so stale containment leaks into the recovered request; and post-compute Runtime-control poison is announced as unauthorized provider activity despite being an internal control failure. V40 adopts the exact candidate only as frozen rejected evidence and authorizes failure-first owning correction within the same 24 paths: add a bounded owner-aware saturated fallback that preserves current exact Host or active global containment through reentrant Runtime-control fencing, never attributes an unmatched record to unrelated work, yields exact signal authority after the fence, and retains every accepted Host identity until exact claim or settlement; make atomic settlement/claim disposition classify no-effect failed claims from exact control-or-deferred authority without a separate precheck TOCTOU; bind poisoned settlement cleanup marker and cancellation to one fail-safe token while retaining exact Host acceptance locally, clear only after strict proof, and prove the first recovered request is clean; project Runtime-control poison as containment-failed/internal-failure with exact truthful visible/VoiceOver copy "Keiko hat einen internen Laufzeitfehler erkannt; die Laufzeit wurde beendet.", preserving the cleanup-unverified watchdog and provider-violation copies for their exact signatures. Add direct, production deferred, reentrant callback, full-capacity, wrong-ID, turn/readiness poison, fresh-recovery, DOM/live-region, and AX-mirror regressions. Update exact parent v130/child v40/Integrated packaged macOS acceptance for the Codex tracer #104 v43 constants; then fresh complete qualification, exact scope, findings-zero audit, signed delivery, and guarded child merge only to epic/98-codex-tracer. No new path, schema, 100/5,000 ms budget, display/package boundary, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, credential, or merge-boundary change.

• V38 audit/authority stop and v39 exact settlement, pending ownership, and signal-authority correction: Exact staged v38 successor candidate 1c2882d95cb631a5078e2bc67d3fb1916b7213b8a4dfe17bf14ed9c4ea056fd8, 24 paths, +10619/-715, base/target 535b0162, stash 903a54a9, no unstaged/untracked path, passed exact Clippy, Host 266/266, frontend 72/72 plus typecheck, evidence/accessibility 78/78, and formatting. Mandatory audit returned four unique P1 contract classes: a rollback-preserved ReservedHost token has no production failed-claim settlement consumer and can accumulate until unrelated unscoped overflow; poisoned multi-record retention expires unmatched exact Host records after five seconds instead of retaining them until exact claim/settlement; global workspace/shutdown cancellation and idle proof omit a pending reservation, allowing readiness on an invalidated workspace or false cleanup success; and the otherwise coherent request/generation/ProcessIdentity signal correction crossed the frozen v38 trust-boundary authority. V39 adopts the exact candidate only as frozen rejected evidence and authorizes failure-first owning correction within the same 24 paths: preserve request/generation/cancellation/full-ProcessIdentity authority through every TERM/KILL effect across direct, deferred, renderer-loss, containment, shutdown, workspace-change, and ControlFailed entry points; keep reentrant deferred installation enqueue-first and nonblocking. Move superseding rollback authority into bounded typed exact-request storage, let the original failed-claim settlement atomically extract it by explicit request ID for both Runtime/Host publication samples and finalization, then retire it exactly once without Host replay. Retain every unmatched accepted Host record until its exact request claims or settles, including beyond the normal terminal window; bounded capacity exhaustion must block/fail closed without converting records into an unrelated request cancellation. Treat pending identity/generation as cancellable cleanup ownership: global/workspace/shutdown cancellation supersedes it in healthy and poisoned recovery, forces compare-scoped rollback, and wait/idle/recovery proof requires no running or pending reservation; readiness revalidates workspace authority before effects. Add deterministic hooks and production regressions for original settlement, wrong-ID isolation, delayed multi-record retention, more than 64 sequential settled races with empty storage, healthy/poison pending turn/readiness workspace-change and shutdown, all stale-signal entry points, exact ControlFailed TERM+KILL, and reentrant terminal callbacks. Update exact parent v129/child v39/Integrated packaged macOS acceptance for the Codex tracer #104 v42 constants; then fresh complete qualification, exact scope, findings-zero audit, signed delivery, and guarded child merge only to epic/98-codex-tracer. No new path, schema, 100/5,000 ms budget, display/package boundary, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, credential, or merge-boundary change.

• V37 audit stop and v38 atomic fresh-claim correction: Exact staged v37 candidate a75e05a355f34878f8de87a86982d63aac29ac6f14ad1b3735d9c92b8f691c37, 24 paths, +9637/-713, base/target 535b0162, stash 903a54a9, no unstaged/untracked path, passed exact Clippy, Host 258/258, frontend 72/72 plus typecheck, evidence/accessibility 78/78, canonical formatting, and exact scope. Four-role audit returned two findings-zero roles and one unique P1 class with two interleavings: retained recovery is proven before reserving the fresh request, so an exact new cancellation or Host-control failure can be lost at commit; and post-begin retained-work failure unconditionally resets control, so a concurrently installed newer ControlFailed token can be erased while its marker remains. V38 freezes every v37 byte and authorizes only failure-first owning correction within the same 24 paths: reserve the new pending request identity and effect generation under Runtime control before retained-resource reconciliation; bind the old closed recovery marker/token snapshot to that reservation; exact cancellation for the reservation or Host ControlFailed must supersede the old token and force claim abort; commit running/begin only if reservation, generation, marker, and old token still match; all pre-begin and post-begin failure/reset paths must compare-and-clear only their own reservation and preserve any newer marker/token/authority. Add deterministic hooks pausing reconciliation before commit and post-begin rollback, with exact new user cancellation and Host ControlFailed interleavings proving zero provider effect, newer authority preservation, no stuck marker-without-token, later strict recovery, and two-claim exclusion. Update exact parent v128/child v38/Integrated packaged macOS acceptance for the Codex tracer #104 v41 constants; then fresh complete qualification, exact 24-path staging, findings-zero four-role audit, signed delivery, and guarded merge only to the epic branch. No new path, schema, budget, display/package boundary, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or other behavior is authorized.

• V36 qualification stop and v37 exact formatting correction: The accepted v36 composed-poison/retained-recovery overlay passed exact Clippy, Host 258/258, frontend 72/72 plus typecheck, evidence/accessibility 78/78, Rustfmt, diff, and exact 24-path scope. Frozen staged v35 candidate remains daec4ba60fa08dea3bea1aaa06fecec7b51bad9ec1c568cc9f724e2a0104408b; exact six-path unstaged v36 overlay is b6bff1157c72890b4b3d913a81940e4f5d37a4d42726087dea0d2e99f5d6fdf0, +287/-91, with no other unstaged/untracked path. The canonical whole-file Prettier check then stopped solely on one staged-v35 invalid-readiness-fingerprint loop in quality/codex-tracer-acceptance.test.mjs: expand the four-element invalid array to one entry per line and wrap the includes call; Prettier output shows no other byte. V37 freezes both layers and authorizes only that exact semantics-neutral Prettier output, exact parent v127/child v37/Integrated packaged macOS acceptance for the Codex tracer #104 v40 constants, fresh complete qualification, exact 24-path staging, findings-zero four-role audit, signed delivery, and guarded merge only to the epic branch. No production/test meaning, new path, schema, budget, display/package boundary, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or other formatting byte is authorized.

• V35 audit stop and v36 composed-poison/retained-recovery correction: Exact staged v35 candidate daec4ba60fa08dea3bea1aaa06fecec7b51bad9ec1c568cc9f724e2a0104408b, 24 paths, +9434/-713, base/target 535b0162, stash 903a54a9, no unstaged/untracked path, passed exact Clippy, Host 257/257, frontend 72/72 plus typecheck, and evidence/accessibility 78/78. Four-role audit returned one findings-zero accessibility role and three unique P1 classes: the Runtime-control-poison arm collapses Host ControlFailed with ordinary completion and preserves a prior future cancellation without setting retained cleanup; non-retained readiness finish_request can clear the cleanup marker while process-group absence remains unproven, causing permanent recovery denial; and workspace generation changes unconditionally erase the cleanup-unverified warning/gate before fresh readiness. V36 freezes every v35 byte and authorizes only failure-first owning corrections within the same 24 paths: in both healthy and poisoned Runtime-control arms distinguish HostCancellationMutation::ControlFailed, replace absent or prior cancellation with one detection-time AcceptedRuntimeCancellation::closed, set the owned cleanup marker, perform immediate authenticated signal/kill, and retain reconciliation; make every finish/reset path preserve the marker and closed token whenever any process group, owned child, reader/turn/publication worker, or work-directory absence remains unproven, let fresh claim atomically reconcile those resources, and clear recovery state only after strict proof; cover Host-poison × Runtime-poison × absent/prior-window and readiness retained-then-dead recovery. Preserve cleanup-unverified turnState across workspace selection, replacement, clear, and generation change while invalidating runtime readiness; keep warning/task/submit/programmatic gates through failed/unavailable recovery on the new workspace; only a fresh ready response for the current workspace generation may clear/re-enable. Add production, matrix, concurrency, and real-root workspace/recovery regressions; update exact parent v126/child v36/Integrated packaged macOS acceptance for the Codex tracer #104 v39 constants; then fresh complete qualification, exact 24-path staging, findings-zero four-role audit, signed delivery, and guarded merge only to the epic branch. No new path, schema, budget, display/package boundary, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or other behavior is authorized.

• V34 audit stop and v35 closed-poison/recovery-surface correction: Exact staged v34 candidate 5e9a66e3cd572466817901348f8af087f83671f1f675924ce293b9d2673bb160, 24 paths, +9226/-712, base/target 535b0162, stash 903a54a9, no unstaged/untracked path, passed exact Clippy, Host 257/257, frontend 72/72 plus typecheck, and evidence/accessibility 78/78. Four-role audit returned one findings-zero structure role and two unique P1 classes: Host-control failure installs a fresh +4,500/+5,000 ms Runtime window, contrary to CloseContainment and the invariant that poison never grants future time; and the cleanup-unverified terminal warning conflicts with an adjacent retry hint, stale ready state, enabled task surface, and no required recovery proof. V35 freezes every v34 byte and authorizes only failure-first owning corrections within the same 24 paths: on HostCancellationMutation::ControlFailed for any active/pending Runtime request, replace rather than preserve any cancellation with AcceptedRuntimeCancellation::closed at the detection instant, signal owned runtime/process state immediately, publish fail-closed truth without a new window, retain cleanup/fresh-claim exclusion until strict absence proof, and invert both fresh/prior-window tests to require cleanup_cutoff and terminal_cutoff no later than observed detection. For the exact containment-failed/internal-failure/cleanupComplete=false watchdog signature, preserve the exact status copy and use exact recovery hint "Die Bereinigung ist nicht bestätigt. Prüfen Sie die Codex-Bereitschaft erneut, bevor Sie fortfahren."; invalidate stale runtime readiness synchronously, disable task editing and submission, reject programmatic start, expose the existing readiness action, keep the warning on failed/unavailable recovery, and only clear the warning/re-enable task and submit after a fresh readiness response proves ready. Add real-root, keyboard/control, failed-recovery, successful-recovery, prior-cancellation poison, process cleanup, and cutoff regressions; update exact parent v125/child v35/Integrated packaged macOS acceptance for the Codex tracer #104 v38 constants; then fresh complete qualification, exact 24-path staging, findings-zero four-role audit, signed delivery, and guarded merge only to the epic branch. No new path, schema, product budget, display/package boundary, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or other behavior is authorized.

• V33 scope stop and v34 owning-presentation path correction: The v33 five-class correction passed exact Clippy, Host 257/257, frontend 72/72 plus typecheck, and evidence/accessibility 78/78. Root review correctly moved the exact cleanup-unverified watchdog copy from an imperative post-React DOM overwrite into the owning turnPresentation function, but final scope authentication then stopped because native/frontend/src/foundation.ts was not in the frozen 23 paths. No commit, push, PR, or audit occurred. Exact staged 23-path v33 layer is SHA-256 ee127f03b9d017ad7d0d878f5d8a4874944b881aaa58f88a0ec729a5e8a6e279; sole unstaged foundation delta is SHA-256 5bf5a932bdd81ea3e57236f6874c62a487202f1f89db2832ccaa003f62b6096b; no other unstaged/untracked path. V34 freezes both layers and authorizes only adding existing native/frontend/src/foundation.ts as the twenty-fourth path so the shared React presentation owner selects the already accepted exact watchdog copy from existing containment-failed/internal-failure/cleanupComplete=false fields while preserving the generic containment copy for all other views; retain synchronous main commit and existing accessibility/real-root regressions; update exact parent v124/child v34/Integrated packaged macOS acceptance for the Codex tracer #104 v37 constants; then fresh complete qualification, exact 24-path staging, findings-zero four-role audit, signed delivery, and guarded merge only to the epic branch. No imperative DOM mutation, other byte/path, schema, budget, display/package boundary, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or behavior is authorized.

• V32 audit stop and v33 consolidated owning correction: Exact fully staged v32 candidate 53fc2bbb2320b4d0f29d491adaa0e233780920543bac9c89caa08addda1f68db, 23 paths, +8948/-714, base/target 535b0162, stash 903a54a9, no unstaged/untracked path, passed exact Clippy, Host 255/255, frontend 69/69 plus typecheck, and evidence/accessibility 78/78. Four-role audit returned one findings-zero structure role and five unique obligations: the Integrated packaged macOS acceptance for the Codex tracer #104 fingerprint loses its final byte and readiness fingerprint shape is not validated; an invalid or contradictory provisional channel event after cancellation disarms the watchdog and authoritative response; watchdog presentation falsely claims provider interception and verified runtime termination despite cleanup-incomplete evidence; Host lifecycle poison returns an empty cancellation that Runtime ignores, leaving the owned provider running; and the Tauri +4,999 test depends on a worker completing inside one wall-clock millisecond. V33 freezes every v32 byte and authorizes only failure-first owning corrections in the same 23 paths: bind the exact 64-hex Integrated packaged macOS acceptance for the Codex tracer #104 identity and validate all parent/child/consumer readiness fingerprints as lowercase SHA-256; while the cancellation watchdog is active, keep malformed, mismatched, or contradictory channel events non-visible and provisional without rejecting or clearing the watchdog so only a verified authoritative response or the watchdog settles; preserve existing non-cancellation failure behavior; present watchdog containment with the exact truthful copy "Keiko konnte die Beendigung des Codex-Laufs nicht bestätigen. Starten Sie keinen neuen Lauf." when state is containment-failed, reason is internal-failure, and cleanupComplete is false; distinguish Host-control failure from unauthorized/invalid cancellation, keep Ignore for the latter, route the former through Runtime CloseContainment for the exact active request, signal and clean owned runtime/process state, and block fresh claims until proof; make the retained Tauri +4,999/+5,000/+5,001 matrix hermetic with the coherent injected clock and synchronized worker admission/completion, never a one-millisecond scheduler race or wall-clock sleep. Add production adapter, port, real-root/live-region, identity-shape, and deterministic timing regressions; update exact parent v123/child v33/Integrated packaged macOS acceptance for the Codex tracer #104 v36 constants; then complete fresh qualification, exact-scope staging, findings-zero four-role audit, signed delivery, and guarded merge only to the epic branch. No new path, schema, budget, allow attribute, display/package boundary, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or other behavior is authorized.

• V31 qualification stop and v32 exact lint correction: The accepted v31 overlay passed Host 255/255, frontend watchdog 47/47 plus typecheck, and retained evidence/accessibility 78/78. The exact production lint gate then stopped on four pre-existing staged-v30 warnings in already authorized paths: runtime run_turn_with_settlement has eight arguments, the cfg(test) reader-hook return tuple is too complex, turn preparation manually returns an Err instead of question-mark propagation, and lib terminal_reason needlessly borrows an existing reference. V32 preserves every v31 behavior and authorizes only failure-first or compile-equivalent mechanical corrections: group the six run-turn data arguments in one borrowed input struct without changing values/order/lifetimes; name the exact test-only reader-hook tuple with a cfg(test) alias; replace the explicit Err return with question-mark propagation; remove the redundant borrow; update exact parent v122/child v32/Integrated packaged macOS acceptance for the Codex tracer #104 v35 constants; then rerun complete qualification, exact-scope staging, findings-zero four-role audit, signed delivery, and guarded merge only to the epic branch. No allow attribute, new path, schema, budget, display/package boundary, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or other behavior is authorized.

• V30 audit stop and v31 effect-time/user-visible deadline correction: Exact staged 23-path v30 candidate SHA-256 ebad6ac96cba09922d60ea000108f35830a6d76d0a542e55c8f8a2fe2671cb2d, +8425/-672, base/target 535b0162, stash 903a54a9, no unstaged/untracked path, passed host 254/254 and all unchanged focused suites. Four-role audit returned one findings-zero role, one source-clean architecture role, and three roles confirming two unique P1 classes: publication time is sampled before spawning the worker, so scheduler delay or a blocking send can start/complete the callback after the Host cutoff while the caller merely returns Deferred; the test pins only pre-spawn started_at and accidentally gives real timeout duration, masking the race. Separately, the +5,001 path suppresses the callback but its encoded containment response still renders and announces a terminal after cutoff, so user-visible settlement is not deadline-owned. V31 freezes every v30 byte and authorizes only failure-first owning corrections within the same 23 paths: use one coherent injectable monotonic publication clock, recheck the authoritative Host cutoff inside the worker immediately before the channel effect, close equality to newly-started work, validate completion against the cutoff, and ensure any crossing result remains invalid provisional state that never renders or announces; replace the masked test with synchronized worker-delay and completion-crossing regressions at +4,999/+5,000/+5,001 using the real wait clock. Add a renderer-owned fail-closed deadline watchdog anchored at cancellation intent, using the existing 4,500 ms cleanup reserve and existing containment-failed TurnView only, so if neither verified callback/response has committed, the stable live region commits one cleanup-incomplete containment terminal before the later Host +5,000 cutoff; cancel it on verified terminal, ignore every later callback/response, and test real createRoot/live-region behavior with fake monotonic time. Preserve normal response authority, exact stopping commit, one terminal, all schemas, the 100/5,000 ms product budgets, and current display/package/Integrated packaged macOS acceptance for the Codex tracer #104 boundaries. Update exact parent v121/child v31/Integrated packaged macOS acceptance for the Codex tracer #104 v34 constants. No other byte/path/behavior is authorized. Then fresh complete qualification, exact-scope restaging, findings-zero four-role audit, signed commit, full local/package/physical/remote evidence, replacement PR, exact-head settlement, and guarded epic-branch merge. Stop and replan on any other change, late valid callback/announcement, duplicate terminal, failed gate, audit finding, evidence mismatch, remote blocker, or non-epic merge.

• V29 audit stop and v30 Host-cutoff-source correction: Exact staged 23-path v29 candidate SHA-256 17cedeb4cf2649a9b15216772cf2b0bd3a90b5d0bf97f79dae5463009387333c, +8279/-683, base/target 535b0162, stash 903a54a9, no unstaged/untracked path, passed host 253/253, application 22/22, frontend 67/67, evidence/accessibility 78/78, source security, format, and diff checks. Four-role audit returned two findings-zero roles and two roles with the same single P1: PreparedTerminalPublication.terminal_cutoff is derived only from Runtime acceptance, while Host may hold the authoritative accepted token after Runtime poison or mismatch; None then grants Tauri a fresh relative 100 ms window and a different Runtime token may grant a later cutoff, permitting a callback after literal Host +5,000 ms before response-side containment. V30 freezes every v29 byte and authorizes only a failure-first owning correction within the same 23 paths: Host publication preparation must expose and carry the authoritative Host accepted cutoff independently of Runtime-token agreement; the production terminal worker must use only that Host cutoff whenever Host cancellation exists and must never replace it with a fresh/later Runtime budget; missing/different/poisoned Runtime-token production/Tauri regressions at Host +4,999/+5,000/+5,001 must prove identical valid callback/response at or before the inclusive cutoff, no callback after it, and truthful containment response. Update exact accepted parent v120/child v30/Integrated packaged macOS acceptance for the Codex tracer #104 v33 constants. No other byte/path, schema, budget, package hook, persisted identity, display contract, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or behavior is authorized. Then run fresh focused and complete qualification, exact-scope restaging, findings-zero four-role audit, signed commit, local green/high audit, package/physical evidence, replacement PR, exact-head settlement, and guarded merge only to epic/98-codex-tracer. Stop and semantically replan on any other change, failed gate, audit finding, evidence mismatch, remote blocker, or non-epic merge attempt.

• V28 audit stop and v29 retained-settlement/DOM correction: Exact staged 22-path v28 candidate SHA-256 3ce858cd0a8e958696fcfbbc0f45e60847eb06ce88c688479925dd5f25928ff0, +7618/-693, base/target 535b0162, stash 903a54a9, no unstaged/untracked path, passed application 22/22, host 250/250, frontend 65/65, evidence/accessibility 78/78, direct source security, Rustfmt, Prettier, and diff checks. Fresh four-role audit returned P0=0 but five unique P1 classes: a deferred original terminal can arrive provisionally just before the differing cleanup-failed response and make the renderer reject the authoritative terminal; terminal-before-ack invokes stopping and terminal renders in one React continuation so concurrent rendering may omit an actual DOM stopping commit; shutdown/workspace cleanup can report success while retained reader, turn, or publication workers remain live; a deferred terminal send that later fails discards its result instead of installing renderer-loss authority; and pre-publication spawn cancellation discards kill/wait failures and can claim clean recovery without retained process ownership. V29 freezes every v28 byte and authorizes only failure-first owning corrections for those findings within the existing 22 paths plus native/frontend/src/main.ts: make the encoded response authoritative over a mismatching stale provisional callback while never rendering the stale terminal, bind publication validity/waiting to the remaining literal Host cutoff, and prove one durable terminal before/at/after +5,000 ms; synchronously commit the exact stopping status to the real DOM before releasing a pending terminal and prove the same live-region node transitions stopping then terminal; include retained readers, turn workers, and publication workers in bounded shutdown/workspace cleanup truth; preserve deferred publication completion disposition so late false/panic installs the exact renderer-loss Host transition only after runtime settlement and blocks fresh claims until settled; and make post-spawn/pre-publication rollback fallible, process-group-aware, authenticated, reaped or explicitly retained so clean cancellation and fresh work require absence proof. Update exact accepted parent v119/child v29/Integrated packaged macOS acceptance for the Codex tracer #104 v32 constants and add genuine production/Tauri/React/shutdown/workspace/spawn rollback regressions. No other path, schema, 100/5,000 ms budget, package hook, persisted identity, display contract, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or unrelated behavior is authorized. Then run fresh focused and complete qualification, exact-scope restaging, findings-zero four-role audit, signed commit, local green/high audit, package/physical cancellation evidence, replacement PR, exact-head settlement, and guarded merge only to epic/98-codex-tracer. Stop and semantically replan on any other byte/path, stale provisional render, coalesced stopping, false cleanup, lost renderer transition, unowned process, failed gate, audit finding, evidence mismatch, remote blocker, or non-epic merge attempt.

• V27 findings-zero audit stop and v28 ownership correction: Matching parent v117/child v27/Integrated packaged macOS acceptance for the Codex tracer #104 v30 readiness produced exact fully staged 22-path candidate SHA-256 d212e3e821a0889610d55399bf405884342c2fb0132be614b25a64a3d46f2247, +6489/-457, base/target 535b0162, stash 903a54a9, and no unstaged/untracked path. Fresh sequential qualification passed application 22/22, host 245/245, frontend 64/64, evidence/accessibility 77/77, source security across 28 productive files, Rustfmt, Prettier, and diff checks. Mandatory four-role audit returned P0=0 but five unique P1 classes: late successful terminal send exposes a cleanup-failed callback before post-effect revalidation returns contradictory containment-failed response; synchronous in-flight reversible effects and direct rollback can outlast the +5,000 ms terminal cutoff; initialize can write after literal Host cancellation accepted between authorization and revalidation; retained-reader reconciliation temporarily removes ownership before running CAS and permits a concurrent fresh claim; and observe-stopping accepts final cancelled text while terminal-before-ack can skip the stable stopping projection. V28 freezes every byte and authorizes only failure-first owning corrections within the same 22 paths: an owned deadline-bounded terminal-publication commit protocol with provisional callback state, exact callback/response identity for every valid completion, no user-visible late/failed worker result, and retained rather than detached publication ownership; owned deadline-aware execution and rollback for long reversible bind/directory/stage/spawn/publish/reader work so cancellation publishes one truthful terminal by cutoff, retains unfinished ownership, blocks fresh claims, and rolls back before recovery; a true irreversible initialize linearization point that keeps Host acceptance prompt before the write and proves zero provider bytes when cancellation wins; atomic retained-reader reconciliation with fresh claim; exact stopping-only packaged observation and a production port race that commits stopping before a raced terminal; exact accepted parent v118/child v28/Integrated packaged macOS acceptance for the Codex tracer #104 v31 constants; and genuine blocked-past-cutoff, late-publication, zero-initialize-byte, two-claim-reader, and terminal-before-ack regressions. No new path, schema, 100/5,000 ms budget, package hook, persisted identity, display contract, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or unrelated behavior is authorized. Then run fresh focused and complete qualification, exact-scope restaging, findings-zero four-role audit, signed commit, local green/high audit, package/physical cancellation evidence, replacement PR, exact-head settlement, and guarded merge only to epic/98-codex-tracer. Stop and semantically replan on any other byte/path, detached worker, late valid terminal, post-cancel provider byte, fresh-claim overlap, missed stopping projection, failed gate, audit finding, evidence mismatch, remote blocker, or non-epic merge attempt.

• V26 aggregate-scanner stop and v27 exact test-local correction: Matching parent v116/child v26/Integrated packaged macOS acceptance for the Codex tracer #104 v29 readiness froze exact complete 22-path candidate SHA-256 55d66ac6ec7bbc4bcd1232a012424d51bba801b1f03cbdac00e1a636b263d6f3, staged layer d21866d8ca608b1db386b390f5747ae26c7df7f4e86ba20d49718e5867666011, unstaged seven-path delta 6916528d91bb1509cfaac3cde5bc7a61f0329d6c8c17be7a2a12f4c8aa68291d, base/target 535b0162, and stash 903a54a9. Bounded diagnosis proved the exact cancellation test 10/10 green unloaded in 0.75–1.00 s and green under concurrent frontend/evidence load with truthful terminal and cleanup; v26 applied the authorized direct terminal_cutoff assertion, scanner-safe effect-permit rename, and exact v116/v26/v29 constants. Direct per-file scanning then revealed seven further candidate-added test locals matching the same aggregate credential-assignment pattern: one host_token in the runtime.rs test module, three host_token plus one runtime_token in turn.rs, and two host_token in tauri_adapter_tests.rs. V27 freezes every byte and authorizes only semantics-neutral renaming of those exact seven test locals, exact accepted parent v117/child v27/Integrated packaged macOS acceptance for the Codex tracer #104 v30 constants in the existing four quality paths, and one fresh sequential focused/complete qualification, exact-scope restaging, findings-zero four-role audit, signed commit, local green/high audit, package/physical cancellation evidence, replacement PR, exact-head settlement, and guarded merge only to epic/98-codex-tracer. No production byte, behavior, product constant, path, schema, budget, package hook, persisted identity, display contract, or Integrated packaged macOS acceptance for the Codex tracer #104 implementation may change. Stop and replan on any additional scanner class or match or any fresh failure.

• V25 qualification stop and v26 deterministic-gate correction: Matching parent v115/child v25/Integrated packaged macOS acceptance for the Codex tracer #104 v28 readiness produced exact complete 22-path candidate SHA-256 fbbf53e073ecda9ce2ccb0773a15d200eeb10488bb10b5f9fce99c0298e750cc, staged layer d21866d8ca608b1db386b390f5747ae26c7df7f4e86ba20d49718e5867666011, unstaged seven-path delta a434ded3f454f51a9fccd0ca8e620c477eb2fe7c75ae1e530cb84c5a375aaa40, base/target 535b0162, and stash 903a54a9. Implementer-focused suites passed host 245/245, frontend 64/64, evidence/accessibility 77/77, Rustfmt, Prettier, scope, and diff checks. Independent qualification then stopped before staging: a host run concurrent with the repository Node suite passed 244/245 and only user_cancel_turn_reports_stopping_then_cancelled_and_cleans_the_tree exceeded its incidental two-second wall-clock assertion at 2.472 s while producing clean cancellation below the unchanged five-second product contract; the repository Node suite passed 832/834 with one intentional skip and failed only source-sensitive-content because the added local text authorization = match matches the existing credential-assignment scanner. V26 freezes every candidate byte and authorizes only bounded unloaded and concurrent-load diagnosis of that exact test; a semantics-neutral local rename in runtime.rs eliminating the scanner match; if and only if diagnosis confirms no product deadline, cancellation, cleanup, reader, or process-ownership defect, replacement of the incidental two-second assertion with a direct monotonic assertion against the literal accepted cancellation terminal cutoff; exact accepted parent v116/child v26/Integrated packaged macOS acceptance for the Codex tracer #104 v29 constants in the same four quality files; and one fresh sequential focused/complete qualification, exact-scope restaging, findings-zero four-role audit, signed commit, local green/high audit, package/physical cancellation evidence, replacement PR, exact-head remote settlement, and guarded merge only to epic/98-codex-tracer. No product constant, source behavior, path, schema, budget, package hook, persisted identity, display contract, or Integrated packaged macOS acceptance for the Codex tracer #104 implementation may change. Stop and semantically replan if diagnosis contradicts the coarse-test cause or any fresh gate fails.

• V24 second-audit stop and v25 publication/effect-ownership correction: Matching parent v114/child v24/Integrated packaged macOS acceptance for the Codex tracer #104 v27 readiness was accepted. V24 corrected current readiness identity, exact-boundary observer timeout, actual production callback/response composition, deferred cancellation claim, stale-workspace settlement, fallible reader creation, prelaunch effect ordering, and bounded race receives. Focused suites passed application 22/22, host 243/243, frontend 64/64 plus typecheck, evidence/accessibility 77/77, format, diff, scope, and snapshot checks. Exact 22-path staged candidate was +5566/-410 with SHA-256 d21866d8ca608b1db386b390f5747ae26c7df7f4e86ba20d49718e5867666011, no unstaged/untracked/unmerged path, base/target 535b0162, and stash 903a54a9. Fresh four-role audit returned P0=0 but confirmed five remaining P1 obligations: a successful final send is validated only before the callback effect and can complete after +5,000 ms while retaining pre-cutoff state; packaged terminal elapsed is sampled after display inspection rather than immediately after terminal observation; the seven labelled prelaunch regressions invoke one helper instead of actual production boundaries; long bind/directory/stage/spawn effects hold the cancellation-authority mutex and can delay literal Host acceptance and stopping beyond 100 ms; and successfully spawned stdout/stderr readers are detached rather than retired before fresh recovery. V25 freezes d21866d8 and authorizes only failure-first tests and owning corrections for those findings within the same 22 paths: update durable readiness constants to exact accepted parent v115/child v25/Integrated packaged macOS acceptance for the Codex tracer #104 v28 versions and fingerprints; give the actual final send a bounded completion contract, revalidate immediately after successful completion, preserve exact callback/response identity for every within-cutoff success, and fail closed without claiming valid terminal evidence if send completion is late or failed; sample packaged terminal time immediately when observe-cancelled returns and before display or other inspection; replace helper-label coverage with injected production-composition traces through each real bind, directory, stage, spawn, publish, reader, and initialize boundary; replace long-held cancellation mutexes with a generation-bound two-phase action protocol that linearizes authorization briefly, leaves literal Host acceptance available within 100 ms, revalidates after each long/reversible effect, rolls back completed work when cancellation wins, and never performs provider initialize after accepted cancellation; retain and retire both successful reader workers as owned resources before work-directory retirement and fresh request, using bounded completion and fail-closed retained ownership rather than detached handles or unbounded join. Add timing tests proving Host acceptance and stopping remain within 100 ms while each long effect is blocked, production call-site tests proving no later effect after cancel, send-completion tests before/at/after +5,000, display-inspection-latency tests, and reader completion/retention/recovery tests. No new path, schema, budget, package hook, persisted identity, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or other behavior is authorized. Then run all focused RED/green groups, complete fresh qualification, exact-scope review/restaging, four-role findings-zero audit, signed linear commit, complete local green/high audit, required package/physical cancellation evidence, replacement PR to the epic branch, exact-head remote/review settlement, and guarded child merge.

• V23 mandatory-audit stop and v24 consolidated owning correction: Matching parent v113/child v23/Integrated packaged macOS acceptance for the Codex tracer #104 v26 readiness was accepted. Immutable corrected candidate a16f6c0e passed complete frontend 64/64 plus typecheck, complete application 22/22 and host 237/237, evidence/accessibility 75/75, Rustfmt, Prettier, diff, scope, and snapshot checks; its 14-path delta was staged atop the frozen v15 layer to one exact 22-path candidate. Fresh four-role audit returned P0=0 with confirmed P1/P2 obligations: durable evidence still binds obsolete v106/v16/v19 readiness; the production active-turn path omits its actual final channel callback and therefore does not prove reentrant send failure or callback-plus-response cutoff; the packaged observer passes zero timeout at the inclusive +5,000 ms boundary and rejects a valid already-visible terminal; exact deferred Host cancellation is not materialized when its request is claimed; ordinary cancellation can win after the preflight check but before directory/stage/spawn/initialize effects; the early stale-workspace terminal publishes outside runtime settlement and can emit a callback that disagrees with its response; stdout/stderr reader thread creation can panic after child registration and orphan the runtime; and one cleanup/cancel race test uses unbounded channel waits. V24 freezes staged SHA-256 a16f6c0eebfc8d8c549949f9de938491a7b7095244c0eb4687cdcf5f12478477, exact 22 paths and +4721/-319, base/target 535b0162, no unstaged/untracked/unmerged path, and stash 903a54a9. It authorizes only failure-first tests and owning corrections for those findings within the same 22 paths: update durable readiness constants to the exact accepted parent v114/child v24/Integrated packaged macOS acceptance for the Codex tracer #104 v27 versions and fingerprints; carry the real production terminal callback through the final settlement envelope without Host/runtime reentrant deadlock, keep runtime cancellation authority through actual callback and encoded response, revalidate the inclusive cutoff after each publication effect, and make channel and response terminal identity exact; allow an already-visible terminal at exactly +5,000 ms while still rejecting every later observation; materialize exact deferred cancellation atomically with request claim and revalidate cancellation before every prelaunch/provider effect so accepted cancellation creates no directory/process/provider write; route stale-workspace terminal through the same fenced settlement; make both reader-thread spawns fallible and on partial failure kill, wait, retire, join, and report truthful cleanup without residue; and replace both unbounded waits with monotonic bounded waits. Add genuine production-composition regressions for failed first/preflight send, no post-cancel prelaunch effect, final-send reentrancy/deadline/response agreement, stale-workspace callback race, each reader-spawn failure/partial construction, inclusive exact-boundary observation, and bounded wait failure. No new path, schema, budget, package hook, persisted identity, Integrated packaged macOS acceptance for the Codex tracer #104 implementation, or wider behavior is authorized. Then run all focused RED/green groups, complete fresh qualification, exact-scope review/restaging, four-role findings-zero audit, signed linear commit, complete local green/high audit, required package/physical cancellation evidence, replacement PR to the epic branch, exact-head remote/review settlement, and guarded child merge.

• V22 frontend-environment stop and v23 verification-only restart: Matching parent v112/child v22/Integrated packaged macOS acceptance for the Codex tracer #104 v25 readiness was accepted. The exact test-only malformed-runtime correction was applied with no production or path change. Its focused exact test passed, the complete pinned offline Rust suites passed application 22/22 and host 237/237, and the retained evidence/accessibility suite passed 75/75. The complete frontend command then completed typecheck but stopped before Vitest startup because the orchestration exported KEIKO_EXPECTED_SOURCE_REVISION; read-only inspection proves Vite requires KEIKO_NATIVE_SOURCE_REVISION, while the former name is only the compiled define. No frontend test, staging, audit, commit, package, physical, push, PR, or merge followed. Exact corrected candidate is 22 paths, +4721/-319, complete binary SHA-256 a16f6c0eebfc8d8c549949f9de938491a7b7095244c0eb4687cdcf5f12478477, with staged v15 layer 4b4d22c8, unstaged SHA-256 b9e9c51ebf2d94811329d1ed247b9aca038957dfb3b461418b8bab00475ddf3a, base/target 535b0162, and stash 903a54a9. V23 is verification and delivery only: make no repository source/test byte before qualification; authenticate the exact candidate and set KEIKO_NATIVE_SOURCE_REVISION=535b0162b9434a152fad967a49b1a738e17acfeb for the complete frontend command under pinned Node 24.18.0/npm 11.16.0; then perform one fresh whole qualification sequence without selective credit, exact-scope two-pass review, stage only the authenticated 14-path unstaged delta atop the frozen layer, four-role findings-zero audit, signed linear commit, complete local green bar and high audit, required cancellation-tranche package/physical evidence, replacement PR to the exact epic branch, exact-head remote/review settlement, and guarded child merge.

• V21 deterministic-fixture diagnosis and v22 owning test correction: The pipeline-safe v21 preflight passed exact readiness and repository snapshots, the non-Cargo smoke passed, twenty serial exact invocations and five batches of eight concurrent exact invocations all passed, and post-run inspection found no surviving Cargo, Rust, or fixture process. Read-only ownership inspection found unique process-and-sequence fixture roots and no runtime-test environment, current-directory, or umask mutation. The unchanged test writes arbitrary bytes without a shebang, while its assertion requires a process to spawn and terminate as protocol-incompatible; the production spawn mapping truthfully classifies a platform PermissionDenied as ContainmentFailed. The observed full-suite failure is therefore a nondeterministic test-fixture contract, not evidence for changing production containment semantics. V22 authorizes only replacing that one test input with an explicit executable shell fixture that starts and exits without emitting the protocol, renaming the test to describe malformed-runtime distinction, and retaining the same Unavailable versus Incompatible assertions. Use the v16 full-suite failure as failure-first evidence; change no production byte or other test. Then run the exact focused test, the complete host and application Rust suites, every previously green focused frontend/evidence/accessibility suite, the complete local green bar and audit, required package/physical evidence, four-role findings-zero audit, signed linear commit, replacement child PR to the epic branch, exact-head remote settlement, and guarded child merge only if every accepted condition passes.

• V20 snapshot-receipt stop and v21 pipeline-free restart: Matching v110/v20/v23 readiness was accepted. The explicit-line outer command printed all three exact readiness passes, then exited before its local snapshot receipt and before every diagnostic action. The bounded output proves no smoke or Cargo invocation ran; the first remaining shell construct was the stash-list/head command under pipefail, so v21 removes every truncating pipeline and reads refs/stash directly. Candidate, index, base, target, and stash bytes remain exact. V21 authorizes diagnosis only: one explicit-line, pipeline-safe outer preflight must independently verify Epic: Governed Codex lifecycle tracer — one workspace, one no-effect turn #98 v111, Defect: Complete turn cancellation within the 5 s terminal bound #188 v21, and Integrated packaged macOS acceptance for the Codex tracer #104 v24 body versions, sole status: ready labels, matching accepted fingerprints, exact base/target, 22-path staged/unstaged counts, hashes, direct refs/stash, and absence of unmerged/untracked files, emit one final pass receipt, and exit before any diagnostic action on mismatch; then one non-Cargo writable-variable/monotonic-elapsed smoke, twenty fresh isolated exact-test invocations, five bounded batches of eight concurrent exact-test invocations, and read-only process/filesystem/runtime-fixture inspection.

• V19 preflight-tokenization stop and v20 explicit-line restart: Matching v109/v19/v22 readiness was accepted and the v19 outer command began.

Exactly one isolated exact-test invocation completed, but the zsh harness then assigned the reserved read-only variable status and exited 1 before recording the Cargo result; no remaining serial run, concurrent batch, or ownership/environment inspection ran.

Focused application 22/22, host 237/237, frontend 64/64, evidence/accessibility 75/75, and formatting/diff checks were green. The first root complete Rust qualification passed application 22/22 and stopped host at 236/237: unchanged runtime::tests::unavailable_host_and_unspawnable_runtime_are_distinct returned ContainmentFailed instead of Incompatible. The same unchanged test had failed once and passed once in complete pre-v16 runs and passed isolated, so no rerun credit is allowed.

Finding and accepted behavior

• Finding source: test and independent read-only audit
• Finding or incident reference: Epic Epic: Governed Codex lifecycle tracer — one workspace, one no-effect turn #98 child Integrated packaged macOS acceptance for the Codex tracer #104 packaged-journey diagnostics on 2026-08-09; one of three checkpoint-labelled runs and one earlier closed packaged run expired after accepted cancellation at observe-cancelled. Preserved draft PR Fix bounded Codex cancellation terminal settlement (#188) #189 and signed head b9890408cdc0e57548c33f229e0cffa237f0d177 attempted the owning repair but are based on obsolete epic tip cf870abaff7029dc036f85d5dcc25fe18f91d15f, are now conflicting, and never completed current-head failure-first, packaged, accessibility, residue, audit, or PR-contract evidence.
• Current baseline and delivered prerequisites: Epic integration tip 535b0162b9434a152fad967a49b1a738e17acfeb, verified tree af459112ed30a989ab96cca1e7deee7a1a6a108d, sole parent 31d772b5bed830dcf8ee7f51265b2711949f1431. Defect: Correct successful workspace projection boundary #187's exact Sonar correction was delivered by PR fix(quality): clarify checkpoint arity for Sonar (#187) #204; fresh push CI 32950319416 and epic-PR CI 32950325429 passed, including macOS 14/26 and aggregate native/CI. Epic PR Deliver governed no-effect Codex lifecycle tracer #157 Sonar is OK with reliability A, 82.8% new coverage, and zero open bugs. Completed Interrupt, cancel, and recover the no-effect Codex run #103 remains the cancellation-policy owner.
• Confirmed cause class: Before the preserved repair, the runtime/session terminal could be published before HostLifecycle applied accepted-cancel precedence, so a raced completion could contradict renderer stopping. Runtime cleanup could also consume the full public 5,000 ms terminal-observation budget, leaving no projection margin. The packaged observer lacked complete fast-failure classification.
• Confirmed preserved candidate behavior: The five signed historical commits 33c489ae, 7b627d7b, 5b290e82, 4fada798, and b9890408 move publication after authoritative settlement, allow truthful stopping -> containment-failed, reserve and derive a bounded terminal-projection margin without increasing 5,000 ms, and classify cleanup/containment terminals. They are provenance only until reapplied and requalified on the current base.
• Remaining confirmed gaps: The arithmetic-only deadline test does not reproduce cancel accepted + stopping + delayed cleanup + terminal publication. HasCancellationProjection currently accepts only stopping/cancelled, so a truthful cleanup-failed or containment-failed visible before the first AX sample can still expire at observe-stopping. Duplicate authoritative terminal updates may cause duplicate live-region announcements and require explicit accessibility adjudication.
• V2 execution stop and v3 correction: On the exact current-base branch, genuine REDs were added only in five authorized test files and executed before salvage: authoritative host settlement returned Completed instead of accepted-cancel Cancelled; delayed cleanup consumed all 5,000 ms before the 500 ms projection reserve; fast AX cleanup/containment terminals lacked CancellationProjection and cleanup was classified adapter-output-invalid; identical authoritative frontend cancellation emitted twice. Those RED bytes are preserved in local stash object 903a54a91a0cb9fea6844f50809f1fa56cf9d2a9. Preserved commits 1–2 and nonconflicting portions of commit 3 were applied without commit, then commit 5b290e82 stopped on one unexpected purely additive conflict in quality/codex-tracer-accessibility-source.test.mjs: current Defect: Correct successful workspace projection boundary #187 workspace/UTF-8 tests versus Defect: Complete turn cancellation within the 5 s terminal bound #188 cancellation terminal probe distinguishes incomplete cleanup, at stage blobs base 7b9e6d28, ours 7190b548, theirs 920e77ec. HEAD remains exact 535b0162; no conflict resolution, commit, push, or PR mutation occurred. V3 authorizes only retaining both complete adjacent test blocks in that file, then continuing the previously authorized salvage and RED restoration. Any semantic overlap, changed assertion, further unexpected conflict, or stash drift stops again.
• V3 execution stop and v4 expectation correction: Under accepted v93/v3, the authenticated additive conflict retained both complete blocks, preserved commits 4–5 and both known commit-5 outcomes were integrated without commit, and exact RED stash 903a54a9 was restored. All four genuine REDs turned green; cargo fmt --check, the host suite 209/209, frontend typecheck, and accessibility suites 23/23 including clang compilation passed. The complete frontend port suite then stopped at 26/28: exactly two unchanged legacy arrays expected duplicate identical final callbacks—normal completed at the existing completion-flow test and cancellation containment-failed at the existing authoritative-failure test—while the accepted exactly-once projection now correctly emits each terminal once. No further edit, commit, push, or PR mutation occurred. V4 authorizes test-only removal of exactly the second duplicate terminal entry in those two existing expected arrays, preserving every preceding state and all production bytes. Any other test change or failure stops again.
• V4 audit stop and v5 whole-defect correction: Under accepted v94/v4, only the two exact legacy duplicate-terminal expectations changed; the staged candidate remained exactly nine paths, +552/-40, binary patch SHA-256 d657df8c387aed56845786fba2c6923aef1f64dc5eff7b0afde6f27f35d24ae9, with RED stash 903a54a9 preserved. Focused gates passed: host 209/209, frontend 28/28, AX 23/23 including clang. Mandatory read-first audit returned aggregate P0=0, P1=4, P2=0: cleanup starts a fresh 4,500 ms window instead of carrying accepted-cancel time; work-directory cleanup and host/final projection are outside that window; the delayed-cleanup tests remain arithmetic-only; the packaged journey can spend independent 5,000 ms waits for stopping and terminal and records no total metric; the canonical tracer environment rejects external/multiple displays; and physical evidence cannot prove one semantic VoiceOver/status announcement. No commit, push, or PR followed. V5 preserves the exact candidate and authorizes only the owning runtime/state-machine and cancellation-tranche evidence corrections below, with matching parent v95, child v5, and Integrated packaged macOS acceptance for the Codex tracer #104 v8 interface readiness required first.
• V5 audit stop and v6 exact-boundary correction: Accepted v5 produced a frozen fifteen-path staged candidate +1239/-141, binary patch SHA-256 32c41477cac7a3bfc488f40e37709cb8ebde5ae35e077d1f14c2afcaaf80e0a5, with no unstaged or unmerged path, no commit/push/PR, and RED stash 903a54a9 preserved. Focused host/application/frontend/AX suites passed, but the exact Node 24 workspace acceptance suite regressed to 5/8. Four independent read-first audits returned aggregate raw P0=0, P1=15, P2=0, consolidated to twelve distinct P1 obligations: runtime timing is not anchored at literal HostLifecycle cancel acceptance; frame and final-publication races remain; the coordinator trace is synthetic; cancellation arriving during synchronous directory removal cannot bind it; poisoned control restarts a future window; worker spawn can panic; containment reasons disagree; Defect: Correct successful workspace projection boundary #187 workspace v1 is broken; impossible temporal ordering validates; physical v2 is discarded; external-display proof is not bound to one semantic Keiko window; and common-status exactly-once coverage omits truthful failure terminals. V6 freezes that rejected candidate and adds exactly request_timing.rs, request_adapter.rs, tauri_adapter.rs, tests.rs, adapter_tests.rs, and tauri_adapter_tests.rs, for twenty-one total paths. It authorizes one typed first-acceptance record created inside HostLifecycle and forwarded unchanged through runtime cleanup and authoritative publication; dynamically cancellation-aware fallible owned cleanup; preserved-or-closed poison behavior; race-linearized frames/final settlement; real production-path injected-clock REDs; restored Defect: Correct successful workspace projection boundary #187 workspace v1; temporally coherent durable evidence; unique semantic Keiko-window-to-display proof; and table-driven terminal status coverage.

Focused gates passed: application 22/22, host 218/218, frontend 38/38, workspace/acceptance/AX 77/77, Objective-C compile, formatting, and diff checks. Mandatory four-role read-first audit returned raw P0=0, P1=23, P2=0, consolidated to sixteen P1 obligations: Host time is sampled before literal mutation; turn cleanup retains a synchronous mid-cancel race; recovery reconciliation can return to synchronous blocking IO; the coordinator trace is synthetic; runtime acceptance identity is discarded before Host cross-check; final callback can publish after cutoff; renderer-loss/shutdown create second windows; cancel can win after protocol projection but before action/product mutation; poisoned handoff can grant a future window; exact +5,000 policy is inconsistent; spawn panic is not fail-closed; workspace-v1 producer/validator remain incompatible; budget/physical terminal facts can contradict; the general journey hard-codes external instead of any display; display binding/topology stability is not rechecked; and the three-terminal DOM table omits exact text plus stopping-to-terminal stable-node proof. V7 freezes the rejected patch and authorizes only these corrections in the same twenty-one paths, with one literal mutation token and one cancellation/publication envelope through every source/action/cleanup/final boundary. Matching parent Epic: Governed Codex lifecycle tracer — one workspace, one no-effect turn #98 v97, child v7, and consumer Integrated packaged macOS acceptance for the Codex tracer #104 v10 readiness is required before edits resume.
• V7 execution stop and v8 exact frontend-composition correction: Accepted v7 implemented the sixteen audit obligations without a new path and preserved one complete 21-path candidate relative to HEAD, +3272/-250, binary patch SHA-256 5b6187a5d1c4da2022d0b67388a2c225c61563b82a34538fda32a324a81e9f23; twelve paths are unstaged over the frozen v6 index, no commit/push/PR occurred, and RED stash 903a54a9 remains intact. Genuine v7 REDs/greens cover literal mutation timing, spawn unwind, asynchronous owned recovery, poisoned handoff, renderer/shutdown tokens, post-projection action fencing without reentrant deadlock, runtime/Host identity and delayed publication, actual cross-layer coordinator, evidence consistency, internal display, repeated binding/topology, and exact common-status text/node proof. Host 225/225, application 22/22, and focused quality 71/71 are green. An accidental broader frontend run then stopped exactly once at unauthorized native/frontend/src/main.test.ts:1112: production renderer composition > lets the cancel control retry after an unaccepted acknowledgement expected terminalRenderCount + 2 but received +1, consistent with the accepted removal of duplicate terminal publication. No edit followed. V8 adds only that test file as path 22 and authorizes replacing the exact + 2 expectation with + 1, then the complete focused/frontend/audit path; production and every other assertion remain frozen.

• V8 execution stop and v9 exit-policy helper correction: Accepted v8 authenticated the frozen candidate, changed only native/frontend/src/main.test.ts:1112 from terminalRenderCount + 2 to +1, and produced a complete 22-path candidate relative to HEAD, +3273/-251, binary SHA-256 111b87b22276238c4489a52f27765f884f40172bdefd878582c66d9a5c3c2efa. Named frontend 1/1, full frontend 64/64, application 22/22, and evidence and accessibility 71/71 passed. The unchanged host rerun then failed at compile only: tauri_adapter_tests.rs:119 still calls removed begin_exit_request_shutdown (E0425) after v7 replaced its production use with typed shut_down_and_stop. No further edit, stage, commit, push, or PR occurred. Restoring an unused test-only legacy helper would not test production. V9 instead authorizes one pure cleanup_failure_prevents_exit(bool) -> bool policy helper in tauri_adapter.rs, requires both production RunEvent::ExitRequested and RunEvent::Exit branches to use it around the existing typed shut_down_and_stop result, and changes the legacy test to call shut_down plus that same helper. No cancellation or shutdown behavior, token forwarding, callback, or other assertion changes.

• V9 formatting-gate stop and v10 exact mechanical normalization: Accepted v9 applied only the authorized pure cleanup_failure_prevents_exit helper, its two production uses, and the one stale-test migration. The complete 22-path candidate remained on exact HEAD/base 535b0162, +3277/-253, binary SHA-256 1c08113f7b7e07adae11a79d97d010fda9ab00e34a4c47896b7f786ac05bb621; cached v6 patch 9526bd0d445dd1811911b215c3517c7b18204c035efc4990cffc316769b2a5f7, index/worktree layering, and RED stash 903a54a9 remained exact. Host/application passed 225/225 and 22/22; frontend passed 64/64 with exact source revision; evidence/accessibility passed 71/71; Rust formatting and both diff checks passed. Repository-pinned Prettier 3.9.6 then failed only five already-authorized files: native/frontend/src/port.test.ts, quality/codex-tracer-acceptance-io.mjs, quality/codex-tracer-acceptance.mjs, quality/codex-tracer-acceptance.test.mjs, and quality/codex-tracer-accessibility.test.mjs. Read-only formatter output proves only line wrapping and operator placement, with no token, assertion, control-flow, data, or semantic change. No formatter write, staging, commit, push, PR, or audit followed. V10 authorizes only applying repository-pinned Prettier 3.9.6 to those exact five paths, then re-running every complete focused suite, formatting and diff checks, staging all 22 paths, two-pass review, and fresh four-role findings-zero audit.

• V10 recovery-test diagnostic stop and v11 read-only reproduction: Accepted v10 applied repository-pinned Prettier 3.9.6 only to the five authorized files, with direct formatting delta +28/-16, no semantic token change, and complete 22-path candidate +3290/-254, binary SHA-256 d6dbea40770addeb842b23c97d81a11a81e37281e8a33ebd7eefefd09de94c23; cached patch, layering, and RED stash remained exact. Frontend 64/64, evidence/accessibility 71/71, Rustfmt, Prettier, and both diff checks passed. The complete Rust command passed application 22/22 but host stopped at 224/225: runtime::tests::retained_work_directories_are_retried_before_the_next_request exhausted its fixed 1,000 thread::yield_now() polls before asynchronous owned recovery allowed the next claim. The same complete host suite had passed 225/225 twice immediately before formatting, and formatting did not touch Rust. Read-only inspection shows the test uses iteration count rather than elapsed time while the production reconciliation worker is asynchronous. No selective retry, source edit, staging, audit, commit, push, or PR followed. V11 is diagnostic-only: preserve every candidate byte and run pinned isolated and concurrent-load repetitions of that exact existing test, recording pass/fail rate and duration, plus read-only process/filesystem observations sufficient to distinguish scheduler starvation, late channel observation, permission restoration, or cross-test interference. Stop after diagnosis and semantically replan before any test/source correction, rerun credit, staging, audit, or delivery.

• V11 diagnostic-harness construction stop and v12 native-loop correction: Matching v101/v11/v14 readiness was accepted with candidate bytes frozen. The first diagnostic command attempted to assemble 20 isolated exact-test invocations through macOS xargs -P1 -I{}. xargs immediately exited 1 with command line cannot be assembled, too long; /usr/bin/time reported effectively zero elapsed time, no Cargo/test process ran, and no repository, index, stash, process, fixture, TMP, or GitHub mutation followed. V11 is consumed and its command is not retried. V12 preserves every candidate byte and replaces only diagnostic orchestration with short native zsh loops: 20 isolated exact-test invocations, then five bounded batches of eight concurrent invocations, each emitting only ordinal/exit status and aggregate elapsed time without files. Stop after recording rates/durations and replan before any correction or qualification rerun.

• V12 recovery-test diagnosis and v13 deterministic-bound correction: Matching v102/v12/v15 readiness was accepted with candidate bytes frozen. The corrected native zsh diagnosis ran the exact existing test 20 times serially and five batches of eight concurrently without files or residue. Serial result was 19/20 pass, 1/20 exact assertion failure, elapsed 8.872 s; bounded concurrent result was 40/40 pass, elapsed 16.210 s. The exact failure reproduced without other tests or a separate load generator. Read-only trace confirms permissions are restored before recovery starts, fixtures are unique, and claim_request schedules one asynchronous worker but the test then grants only 1,000 thread::yield_now() attempts—an iteration count with no completion or elapsed-time guarantee. Concurrent success disproves required cross-test interference; filesystem latency or worker scheduling can both outlast the arbitrary loop and are the same unbounded-test-wait defect class. No source, index, stash, process, fixture, TMP, or Git mutation followed. V13 authorizes only replacing that one .any yield-count block in runtime::tests::retained_work_directories_are_retried_before_the_next_request with a monotonic one-second bounded loop that retries the unchanged active.claim_request("retry-cleanup"), yields between attempts, returns success immediately, and fails with the unchanged assertion if the deadline closes. Production recovery, constants, request identity, assertions, and every other byte remain frozen.

• V13 review stop and v14 inclusive-terminal-boundary correction: Matching v103/v13/v16 readiness applied only the authorized one-second monotonic test loop. The exact test then passed 20/20 serially and 40/40 bounded-concurrently; complete application 22/22, host 225/225, frontend 64/64, evidence/accessibility 71/71, Rustfmt, pinned Prettier, and both diff checks passed. All 22 paths were staged as +3296/-254, binary SHA-256 b852be906332108f56d7db05e969766233264f2cfae8c3f76ba76ea2b5b83271, with exact HEAD/base 535b0162 and RED stash 903a54a9. Mandatory root semantic review then confirmed one P1 exact-boundary inconsistency left from v7: runtime settlement uses Instant::now() >= window.terminal_cutoff, while Host final publication and evidence validators use > and the accepted contract requires +5,000 ms inclusive and +5,001 ms rejected. Existing tests cover +4,999 and +5,001 but omit +5,000. No audit, commit, push, PR, or further edit followed. V14 freezes the staged candidate and authorizes only one shared pure deadline-exceeded comparator with strict now > cutoff, use by runtime settlement and Host final publication, and an exact table-driven +4,999/+5,000/+5,001 regression test. Matching parent Epic: Governed Codex lifecycle tracer — one workspace, one no-effect turn #98 v104, child v14, and consumer Integrated packaged macOS acceptance for the Codex tracer #104 v17 readiness is required first.
• V14 review stop and v15 exact-composition/action-fence/display correction: Matching v104/v14/v17 readiness applied only the authorized strict shared terminal comparator and exact +4,999/+5,000/+5,001 table. Complete application 22/22, host 226/226, frontend 64/64, evidence/accessibility 71/71, Rustfmt, pinned Prettier, and both diff checks passed; all 22 paths were staged as +3325/-254, binary SHA-256 ea14118af0d91f47a005d96edb5b5fd382476fe49d93b2abc5c68e9db6738365, with exact HEAD/base/epic tip 535b0162 and RED stash 903a54a9. Whole-patch root semantic review then confirmed three P1 defect classes before audit: full-v3 identity still emits accepted parent v96/Defect: Complete turn cancellation within the 5 s terminal bound #188 v6/Integrated packaged macOS acceptance for the Codex tracer #104 v9 fingerprints and duplicates them in acceptance IO; the production IO binding normalizer rejects internal displays despite the journey/contract accepting any active internal or external display; and user/renderer/shutdown Host mutation occurs before the runtime action fence is acquired, allowing an already-fenced provider/product action to execute after literal Host acceptance, while page-load replacement still resamples renderer loss. No audit, commit, push, PR, or further edit followed. V15 freezes the staged candidate and authorizes only canonical current readiness binding, one internal-or-external closed binding normalizer, and one runtime-before-Host all-source cancellation handoff fence including page-load replacement, with matching parent Epic: Governed Codex lifecycle tracer — one workspace, one no-effect turn #98 v105, child v15, and consumer Integrated packaged macOS acceptance for the Codex tracer #104 v18 readiness required first.
• Accepted behavior and ownership: Defect: Complete turn cancellation within the 5 s terminal bound #188 owns the bounded cancellation tranche only: accepted cancel projects semantic stopping within 100 ms, then exactly one cancelled terminal or distinct truthful cleanup/containment failure appears within the unchanged 5,000 ms total bound; no late rewrite, false success, accepted late effect, or owned descendant remains; recovery starts only through a fresh preflight. Integrated packaged macOS acceptance for the Codex tracer #104 remains the sole owner of the final full canonical packaged journey after Defect: Complete turn cancellation within the 5 s terminal bound #188 merges.
• User-visible and operational impact: High release blocker. A user must never remain in stopping past the accepted terminal bound, receive a false clean cancellation, or hear duplicate terminal announcements. The correction must work with the Keiko window on any active connected display; no built-in-screen-only or Codex-foreground premise is accepted.
• Severity and rationale: high — intermittent primary-journey lifecycle failure with process/terminal trust-boundary implications, but no current evidence of secret exposure, unauthorized effect, or process escape.

Reproduction contract

• Preconditions: Exact current epic tip 535b0162b9434a152fad967a49b1a738e17acfeb; exact @openai/codex@0.145.0; accepted Defect: Make Codex cleanup coverage proof deterministic #101 containment profile and Interrupt, cancel, and recover the no-effect Codex run #103 terminal policy; sanitized identity-only Git fixture; repository-agnostic fixed no-effect task; operator-granted Accessibility permission; no competing Keiko acceptance process.
• Historical signal: Cancel projected stopping in 43 ms, then observe-cancelled intermittently returned bounded-wait-expired at 5,000 ms. Preserved PR Fix bounded Codex cancellation terminal settlement (#188) #189 is CONFLICTING/DIRTY, with its old exact-head evidence non-current.
• Deterministic RED 1: On the fresh current base, inject accepted cancel, semantic stopping, cleanup that occupies the pre-reserved portion of the deadline, and a terminal projection step. Before the owning repair, the end-to-end terminal exceeds or loses the 5,000 ms settlement contract; arithmetic-only duration comparison is insufficient.
• Deterministic RED 2: Present cleanup-failed and containment-failed before the first AX observe-stopping sample. Before correction, the observer expires instead of immediately classifying the truthful terminal.
• Accessibility check: Exercise the same authoritative terminal arriving through channel and final settlement and prove the live region announces one semantic terminal outcome, or record evidence that platform deduplication already guarantees one announcement without relying on incidental callback counts.
• Expected result: stopping at most 100 ms; one cancelled, cleanup-failed, or containment-failed semantic terminal inside 5,000 ms; exact precedence and one live announcement; zero descendants and accepted late events/effects; fresh recovery only.
• Packaged evidence boundary: Run the canonical packaged command but credit Defect: Complete turn cancellation within the 5 s terminal bound #188 only for the repeated cancellation, semantic terminal, accessibility, redaction, recovery, and zero-residue tranche. Any unrelated full-journey result remains Integrated packaged macOS acceptance for the Codex tracer #104 evidence and cannot be claimed as Defect: Complete turn cancellation within the 5 s terminal bound #188 completion.

Scope

• In scope: Preserve the exact frozen v6 candidate; create the typed first acceptance at the literal Host mutation, not before validation; carry and cross-check that exact identity through explicit user, renderer-loss, and app-shutdown sources, adapters, pending runtime claim, always-owned fallible turn-directory cleanup, always-bounded owned recovery reconciliation, TurnSession settlement, Host precedence, and the final response/channel publication envelope; hold or revalidate cancellation across projection action and every product/provider mutation; one exact +4,500/+5,000 boundary with 5,000 ms accepted and 5,001 ms rejected; poison preserving the first window or immediately closing when absent; panic/Err/disconnect-safe worker ownership; one genuine injected-clock production path; exact workspace-v1 producer/validator compatibility; cross-consistent budget/cleanup/terminal/VoiceOver facts; any-active-display automated journey plus external-only physical tranche; repeated semantic window/display binding with reference/physical topology equality and drift rejection; table-driven exact text and stable common status node across stopping to all three terminals; three repeated cancellation runs; Integrated packaged macOS acceptance for the Codex tracer #104 v10 acknowledgement without ownership transfer.
• Out of scope: Increasing 5,000 ms or 100 ms; treating stopping as terminal; suppressing cleanup/containment failure; automatic replay/resume; changing runtime version; repository-informed tasks; effects/tools/commands; Knowledge; auth/token management; Windows implementation; general desktop automation; full Integrated packaged macOS acceptance for the Codex tracer #104 canonical qualification; Epic: Contract-as-Code migration and lifecycle activation cutover (ADR-0003/ADR-0004) #49 lifecycle implementation.
• Owning modules: request_timing and HostLifecycle jointly own the literal first mutation token; request/Tauri adapters carry it for explicit user, renderer-loss, and shutdown; runtime owns the single cancellation/publication envelope, process action fence, always-owned directory cleanup and recovery; host turn owns runtime-token cross-check, post-lock deadline-safe exactly-once final publication, and exact 5,000 boundary; application owns only exact containment transitions; frontend owns one common status node; tracer acceptance/IO owns workspace compatibility and cross-consistent durable evidence; bounded AX owns nonactivating repeated semantic Keiko-window/display mapping and drift rejection. No product hook or second policy owner.
• Trust boundaries: Untrusted runtime events/process state cross adapter and host boundaries. Signals target only the authenticated owned runtime tree. Prompt/response/path/protocol/process identifiers remain absent from diagnostics and evidence. Keiko remains sole terminal authority.
• Display/accessibility boundary: Evidence may run with the Keiko window on any active connected display. The harness records bounded display topology without serials or user data, locates the window by accepted semantics rather than built-in display identity, and must not require the Codex app to remain foreground outside its own task execution.
• Regression boundary: Preserve Defect: Make Codex cleanup coverage proof deterministic #101 identity/containment, Stream one governed no-effect Codex turn #102 streaming/quarantine, Interrupt, cancel, and recover the no-effect Codex run #103 precedence/recovery, delivered Defect: Correct successful workspace projection boundary #187 workspace semantics/redaction, ADR-0006 package identity, and ADR-0013 AXUIElement exclusion/permission contracts.

• Starting baseline: exact verified epic tip 535b0162b9434a152fad967a49b1a738e17acfeb
• Fresh source identity: create a unique codex/188-cancellation-terminal-v2-535b branch/worktree from the exact starting baseline. Never reuse, rebase, reset, amend, or force-push preserved branch codex/188-cancellation-terminal or PR Fix bounded Codex cancellation terminal settlement (#188) #189.
• Allowed write scope: Preserve and correct only native/crates/keiko-host-macos/src/lib.rs; native/crates/keiko-host-macos/src/request_timing.rs; native/crates/keiko-host-macos/src/request_adapter.rs; native/crates/keiko-host-macos/src/tauri_adapter.rs; native/crates/keiko-host-macos/src/runtime.rs; native/crates/keiko-host-macos/src/turn.rs; native/crates/keiko-host-macos/src/tests.rs; native/crates/keiko-host-macos/src/adapter_tests.rs; native/crates/keiko-host-macos/src/tauri_adapter_tests.rs; native/crates/keiko-application/src/turn.rs; native/frontend/src/port.ts; native/frontend/src/port.test.ts; native/frontend/src/foundation.accessibility.test.ts; native/frontend/src/main.ts; native/frontend/src/main.test.ts; quality/codex-tracer-accessibility-source.mjs; quality/codex-tracer-accessibility-source.test.mjs; quality/codex-tracer-accessibility.mjs; quality/codex-tracer-accessibility.test.mjs; quality/codex-tracer-acceptance.mjs; quality/codex-tracer-acceptance.test.mjs; quality/codex-tracer-acceptance-io.mjs; quality/codex-tracer-acceptance-io.test.mjs; Git index and signed commits on the fresh branch; one replacement child PR and its evidence. No other path. PR Fix bounded Codex cancellation terminal settlement (#188) #189 is closed superseded provenance.
• Correction authority: Preserve the fully staged 22-path candidate relative to HEAD exactly as +3325/-254, binary SHA-256 ea14118af0d91f47a005d96edb5b5fd382476fe49d93b2abc5c68e9db6738365, with RED stash 903a54a9. Within existing authorized host paths, add one runtime-owned cancellation handoff fence that acquires/revalidates runtime control before invoking the literal Host mutation, installs only the matching first Host record before releasing the action fence, preserves-or-closes poison, and signals the owned process afterward. Route explicit user cancel, external renderer loss/window destruction, app shutdown, and page-load replacement through that fence; retain the existing same-thread channel-send-failure deferred path to avoid reentrant deadlock. Page-load replacement must fence and forward the old generation's Host token before starting the new document, never resample it. Add deterministic production-boundary tests proving Host mutation cannot occur while an action guard owns the fence and proving page-load/user/renderer/shutdown all carry the exact Host token. Within existing acceptance paths, make acceptanceIdentityContract the sole readiness-fingerprint owner, set its three values to the exact accepted v105/v15/v18 fingerprints, compose IO bindings from it rather than duplicate literals, and assert all three exact values. Add one pure closed window-binding normalizer used by production IO that accepts only records with display class internal or external, matched display count one, semantic window count one, and no other fields; table-test both display classes and hostile/malformed shapes. Physical-v2 remains external-only; the general automated journey remains valid on either class. Run failure-first focused tests, complete host/application/frontend/evidence suites, Rustfmt/Prettier/diff checks, restage all 22 paths, repeat root two-pass review, and fresh four-role findings-zero audit before commit/full delivery.
• Additional prohibitions: No path beyond the existing twenty-two; no new cancellation timestamp/window/deadline, Host-before-runtime lock order, blocking wait while holding both owners, unowned worker, product hook, display identifier/geometry persistence, unapproved weakening of physical qualification, schema field change, fingerprint placeholder, or duplicated readiness constant. Do not change terminal/cleanup/frontend behavior, budgets, runtime version, credentials, dependencies, branch target, merge boundary, or Integrated packaged macOS acceptance for the Codex tracer #104 ownership. No audit, commit, push, or PR before complete correction and reruns.
• Authorized external mutations: After matching parent v92/child v2 readiness, close stale draft PR Fix bounded Codex cancellation terminal settlement (#188) #189 as superseded without deleting its branch; assign Defect: Complete turn cancellation within the 5 s terminal bound #188 to the executing maintainer identity; create/push the fresh branch normally; create/update one replacement child PR; run the exact owned Codex process tree and bounded AXUIElement/package journey; merge only that green audited child PR into the accepted epic branch; observe resulting exact-tip gates. The parent contract separately authorizes removal of the satisfied Defect: Correct successful workspace projection boundary #187→Defect: Complete turn cancellation within the 5 s terminal bound #188 dependency edge.
• Required credentials or secrets: Existing Git/GitHub delivery credential plus the human-provisioned ChatGPT/keyring profile and operator-granted macOS Accessibility permission. Automation receives availability only and never reads or changes credential values or the macOS privacy database.
• Merge boundary: Guarded agent merge is authorized only from the replacement Defect: Complete turn cancellation within the 5 s terminal bound #188 child PR into epic/98-codex-tracer after all exact-head local/remote/package/accessibility/audit evidence, reviews, and conversations are green/clear. Never merge into dev.
• Additional stop conditions: Stop on pre-edit HEAD/path/hash/stash/readiness drift; inability to establish runtime-before-Host lock order without deadlock; any Host mutation observed while the action fence is held; any source resampling a Host token; current exact fingerprints unavailable or mismatched; internal or external exact binding rejected; malformed binding accepted; any extra byte/path beyond the authorized owning tests/call sites; any gate/review finding; or any prior stop condition.

Quality Plan

• V59 cancellation-action measurement-boundary addendum: RED must model a 140 ms synchronous cancel-turn AX press followed by immediately visible stopping and fail because the current pre-action sample reports 140 ms local projection. GREEN must sample the existing monotonic clock immediately after Press returns, report zero milliseconds for immediate local projection, preserve the separately measured overall adapter action and inclusive 5,000 ms terminal envelope, retain the exact 100 ms local budget and unchanged schema, add no helper/retry/sleep, and rerun focused source tests, generated Objective-C compilation, complete local gates, packaged journey, fresh physical observation, and findings-zero audit.

• V58 measurement-boundary addendum: RED must model a 140 ms synchronous permission-denial native action followed by immediate local projection and fail under the current pre-action projection clock. GREEN must reuse the existing action-return timing owner, preserve the 5,000 ms total action bound and 100 ms local projection bound, emit the unchanged denial evidence schema, add no retry or sleep, and rerun the focused source suite, complete local gates, packaged journey, exact-head physical observation, and findings-zero audit.

• V31 deadline addendum: REDs must delay worker start, block callback completion across cutoff, and withhold callback/response through the real renderer watchdog. GREEN must start no new callback at equality, validate completion on the same clock, keep late provisional results non-visible, and commit exactly one cleanup-incomplete containment terminal on the stable live region by the existing cleanup reserve when Host settlement is absent.

• V30 Host-cutoff addendum: REDs must cover actual Host acceptance with absent, mismatched, and poisoned Runtime acceptance at +4,999/+5,000/+5,001 through production publication composition. GREEN must source the worker deadline from Host alone whenever Host cancellation exists and preserve response containment without any callback after the inclusive cutoff.

• V29 retained-settlement and DOM addendum: REDs must drive actual late terminal success/failure through the production Tauri channel, actual concurrent React DOM commits for terminal-before-ack, shutdown and workspace replacement with each retained ownership class, and injected pre-publication process termination/reap failures. GREEN must commit stopping before terminal, treat the response as authoritative without rendering stale provisional state, retain and propagate deferred failure disposition, report cleanup only after all owned resources retire, and block fresh work until authenticated process absence. Re-run every focused and complete suite and require a fresh four-role P0=0/P1=0/P2=0 audit.

• V25 publication/effect-ownership addendum: REDs must drive the actual production final send through before/at/after cutoff completion; delay display inspection after a valid exact-boundary terminal; block each actual prelaunch boundary while accepting cancellation and measuring <=100 ms Host/stopping projection; prove generation-bound rollback and zero later provider effect; and prove both successful reader workers terminate or remain explicit retained ownership before fresh execution. GREEN must never claim a valid late terminal, hold cancellation authority through long synchronous work, detach a reader, or use helper labels as production evidence. Re-run every focused and complete suite and require a fresh four-role P0=0/P1=0/P2=0 audit.

• V24 audit-correction addendum: Before GREEN, add deterministic tests for the exact first-send deferred token at request claim, each ordinary prelaunch boundary, real final callback send failure/reentrancy plus response identity and post-effect cutoff, stale-workspace callback race, exact +5,000 ms already-visible observation, stdout and stderr thread-spawn failure including partial construction cleanup, and bounded receive failure. GREEN must fix the owning production/evidence layer, retain no child/thread/directory/provider effect after accepted cancellation, and embed only exact current readiness identities. Re-run every focused and complete suite and require a fresh four-role P0=0/P1=0/P2=0 audit.

• V23 verification-only addendum: The v22 source correction and focused/complete Rust plus 75-test evidence results are provenance, not selective qualification credit. Use the exact Vite input name KEIKO_NATIVE_SOURCE_REVISION with the frozen 40-hex base revision, run the complete frontend command, then one whole fresh accepted qualification and delivery sequence at immutable candidate a16f6c0e; no source or test edit is authorized.

• V22 deterministic-fixture addendum: Credit the recorded full-host-suite ContainmentFailed-versus-Incompatible mismatch as the failure-first signal. Correct only the test fixture so the child is a valid executable that deterministically starts and exits without protocol output; do not alter production spawn, staging, permission, containment, or readiness classification. The focused exact test must pass, followed by the complete host and application suites and every retained qualification/audit/delivery obligation.

• V16 failure-first addendum: Before production correction, prove final-channel re-entrance/deadline crossing, cancellation in the runtime-finish to Host-settlement gap, pending multi-record renderer/shutdown loss, Finished/failed-install page-load loss, internal-automated plus external-physical composition, same-class display movement, and the current helper-only coordinator. GREEN must exercise the production entrypoints in one injected trace, keep actual callback and encoded response within the literal Host token cutoff, retain all unmatched records until exact request claim, compare ephemeral window/display identity and position without persistence, and bound every test wait by monotonic time. Re-run every complete focused suite and fresh four-role findings-zero audit.

• Applicable Code Quality Standard areas: Architecture/ownership; correctness/contracts; failure/lifecycle semantics; security/privacy; hermetic and integration tests; performance/resources; UX/accessibility; observability/evidence; maintainability.

• Failure-first evidence: Before production correction, add focused tests that (1) expect all three newly accepted readiness fingerprints and fail against the v96/v6/v9 values, (2) expect the production IO normalizer to accept an exact internal binding and fail against its external-only policy, and (3) hold the runtime action guard while initiating the real adapter handoff and prove the current Host mutation occurs before fence ownership is released plus page-load replacement lacks the Host token. Then correct only the owners/call sites and require all REDs green followed by every complete focused suite; prior v14 greens are provenance only.

• Positive and boundary coverage: Literal token sampling and duplicate identity; explicit/renderer/shutdown sources; pending/wrong request; always-worker cleanup before and after cancel; worker Err/panic/disconnect/late settle; bounded reconciliation; cancel-wins before projection, after projection, and before every derived effect; runtime/Host mismatch; final callback at 4,999/5,000/5,001; callback delay; poison before/after token; workspace-v1 live producer; consistent/contradictory terminal facts; internal/external automated binding; external physical binding; stable/moved window and equal/drifted topology; exact three-terminal status transitions; fresh recovery only after proof.

• Accessibility coverage: Table-driven stopping -> cancelled, cleanup-failed, and containment-failed asserts exact visible text, one stable DOM node, polite/atomic role attributes, one channel/final update, and no duplicate. Automated nonactivating binding accepts any active internal or external display, samples exactly one semantic Keiko window before and after cancellation, rejects movement/ambiguity/topology drift, and persists aggregate classification only. Physical AC5 requires the genuinely observed active internal or external display, exactly one real VoiceOver cancellation announcement, and exact automated/reference/physical aggregate agreement.

• Security/resource coverage: Authenticated process identity before signal/reap; strict absence/retirement proof; zero descendants; no late accepted effects; bounded queues/diagnostics; body-free redacted evidence; no adapter/test marker in the package.

• Local gates: pinned npm ci --ignore-scripts, focused RED/green groups, complete npm run quality, npm audit --audit-level=high, npm run acceptance:macos, Rust host/application tests, and the exact packaged tracer command under the accepted fixed offline toolchain environment.

• Packaged repetition: At least three consecutive exact-head cancellation passes use one literal Host token and one 5,000-inclusive envelope through final callback/response; evidence enforces stopping <= terminal <= 5,000, terminal/cleanup/containment/announced-state consistency, equal stable automated/reference/physical aggregate topology, and the same unique semantic Keiko window on the observed internal or external physical target before/after cancellation. Internal-display automated runs remain valid. All prior recovery, redaction, zero-effect, zero-descendant, zero-residue, and no-selective-rerun rules remain.

• Independent audit: Read-first roles cover architecture, cancellation precedence, process security, deadline accounting, frontend state semantics, AX/accessibility/display behavior, hermeticity, performance/resources, and full evidence mapping. Required final result is P0=0, P1=0, P2=0 with user-facing applicability true and physical observations recorded.

• Delivery/remote gates: Exact signed linear head, applicable CI on macOS 14/26 plus Windows/Linux smoke, CodeQL, OSV, Dependency Review, Socket, canonical PR/issue contract statuses, zero unresolved review threads, and no blocking review before child merge.

Acceptance criteria

• AC1 — Genuine deterministic REDs exercise one actual injected production coordinator from literal Host mutation through all cancellation sources/adapters, already-active process and always-owned directory cleanup, projection/action fence, TurnSession and Host identity cross-check, deadline-safe exactly-once callback/response publication, and blocked-then-fresh recovery; manual helper timelines/states receive no credit.
• AC2 — The first accepted matching Host mutation creates one typed record carried unchanged for user/renderer/shutdown; cleanup and recovery are always fallible, owned, tracked, dynamically cutoff-aware, and bounded; poison never grants a future window; derived actions cannot apply after cancel wins; runtime/Host identity agrees; stopping <=100 ms and exactly one truthful terminal is actually published at or before the inclusive +5,000 ms boundary, with +5,001 rejected.
• AC3 — First/duplicate/pending/unauthorized and all three cancellation sources, completion/timeout/crash, worker Err/panic/disconnect/late settle, poison, projection/action/final races, cleanup/recovery, process exits, and retry preserve exact precedence/reasons, authenticated ownership, no synchronous blocking escape, no false success or late effect, one terminal, zero descendants, and fresh execution only after proof.
• AC4 — Table-driven frontend/DOM/channel/AX proves exact text and one stable polite atomic status node from stopping through each truthful terminal with one update. Automated binding works on any active internal or external display and nonactivatingly proves one semantic Keiko window before/after cancellation with no movement/ambiguity/topology drift or persisted identifiers/geometry; ADR-0013 exclusion remains.
• AC5 — Three consecutive signed packaged cancellation repetitions bind the literal Host token through final publication; enforce stopping <= terminal <=5,000 with mutually consistent cleanup/containment/terminal/VoiceOver facts; durably embed physical v2; prove equal stable automated/reference/physical aggregate topology and one semantic Keiko window on the observed internal or external physical target before/after cancel; and retain one announcement, fresh recovery, zero late effects, descendants, residue, or leakage. Integrated packaged macOS acceptance for the Codex tracer #104 v10 remains sole full-canonical owner.
• AC6 — Complete local/remote gates, findings-zero independent audit, exact PR contract/readiness, reviews, conversations, and child-to-epic delivery settle without deadline/gate/trust-boundary widening.

• Historical v13 stop: matching parent v103/child v13/Integrated packaged macOS acceptance for the Codex tracer #104 v16 governed only the deterministic recovery-test correction and grants no authority for this semantic boundary correction.

• Historical v12 stop: matching parent v102/child v12/Integrated packaged macOS acceptance for the Codex tracer #104 v15 governed diagnosis only and grants no edit, qualification rerun, staging, audit, commit, push, or PR authority.

• Historical v11 stop: matching parent v101/child v11/Integrated packaged macOS acceptance for the Codex tracer #104 v14 governed only the failed xargs construction and grants no retry or further action.

• Historical v10 stop: matching parent v100/child v10/Integrated packaged macOS acceptance for the Codex tracer #104 v13 governed formatting and complete focused reruns through the one host test failure and grants no retry, edit, staging, audit, or delivery authority.

• Historical v9 stop: matching parent v99/child v9/Integrated packaged macOS acceptance for the Codex tracer #104 v12 governed only the exit-policy helper correction through the Prettier gate stop and grants no formatter write, staging, audit, commit, or delivery authority.

• Historical v8 stop: matching parent v98/child v8/Integrated packaged macOS acceptance for the Codex tracer #104 v11 governed only the main-test expectation through the E0425 compile stop and grants no helper correction, commit, full gate, or delivery authority.

• Historical v7 stop: matching parent v97/child v7/Integrated packaged macOS acceptance for the Codex tracer #104 v10 governed the 21-path correction only through the out-of-scope main.test.ts failure and grants no extra-file edit, commit, full gate, or delivery authority.

• Historical v6 stop: matching parent v96/child v6/Integrated packaged macOS acceptance for the Codex tracer #104 v9 governed the exact staged candidate through its mandatory audit; it grants no correction, commit, full-gate, or delivery authority.

• Historical v5 stop: matching parent v95/child v5/Integrated packaged macOS acceptance for the Codex tracer #104 v8 governed only the fifteen-path audit correction attempt; its four-role P1 audit is final and grants no further edit, commit, full-gate, or delivery authority.

• Historical v4 stop: matching parent v94/child v4 governed only two expectation edits and focused gates; mandatory audit found four P1 obligations and v4 grants no audit-fix, commit, full-gate, or delivery authority.

• Historical v3 stop: matching parent v93/child v3 governed the additive resolution, completed salvage, exact RED restoration, and focused gates through the 26/28 frontend semantic-overlap stop; it grants no expectation edit or further gate authority.

• Historical v2 stop: matching parent v92/child v2 authorized the genuine REDs and salvage attempt through the unexpected commit-3 additive conflict; it grants no resolution or further salvage authority.

• Stop if reproduction contradicts the accepted cause, if a RED is setup/compile-only, if any unexpected conflict/path/scope/terminal-owner change appears, or if the preserved patch cannot be safely integrated.

• Stop on any need to increase 100 ms/5,000 ms, weaken truthful failure/cleanup/process proof, signal outside exact ownership, expose sensitive content, mutate credentials/privacy settings, rely on a built-in-only display, or claim Integrated packaged macOS acceptance for the Codex tracer #104's full journey.

• Stop on failed local/package/physical/remote gate or audit finding; diagnose and semantically replan before another attempt. Never selectively rerun or dismiss a failure.

• Never reuse/force-push PR Fix bounded Codex cancellation terminal settlement (#188) #189's branch, push directly to the epic branch or dev, merge into dev, or widen authority through issue/PR edits.
