Canonical base: 06e5154
Correctness/safety review completed against the final two-file diff and current Codex App Server protocol. The earlier environment-isolation gap was not waived: it was repaired by T079-only experimental opt-in plus explicit empty environments/runtime roots/dynamic tools/capability roots, returned-root/instruction-source validation, and future-fail-closed item handling. Stable T077 initialization remains stable-only.
Verified invariants:
- mandatory initialize -> successful response -> initialized before later requests;
- exact runtime identity and exact locally observed version revalidated before launch;
- one ephemeral thread and one fixed bounded prompt only;
- no arbitrary model/prompt/tool/policy surface;
- approvalPolicy=never plus explicit decline on unexpected command/file approvals;
- readOnly + networkAccess=false;
- environment access disabled explicitly;
- zero runtime workspace roots and zero instruction sources required from thread evidence;
- MCP/tool/hook/web-search/image-generation/collaboration/subagent/diff activity is non-authorizing and fail-closed;
- unknown item kinds are fail-closed;
- native thread identity remains separate from Winds session identity;
- model output remains AGENT_RUNTIME_EVIDENCE_NOT_VERIFIED_OR_ACCEPTED;
- cleanup targets only the directly owned child; mutated disposable context is preserved rather than erased;
- no migration, store/domain schema, dependency, main.rs, generic agent surface, or landing automation change.
Exact-head gates:
- quality #739: PASS
- windows-terminal #445: PASS
- release-candidate #502: PASS after same-SHA T063 Windows timing rerun; no code mutation or waiver
- unit: 242 pass / 0 fail / 3 ignored
- T079 deterministic: 7/7 PASS
- live T079 proof: intentionally still PENDING

Exact head: 081998e
YAGNI/minimum-surface review: PASS.
The final diff is limited to the existing Codex protocol module plus one focused T079 test module. The implementation does not add a JSON-RPC framework, async runtime, persistence/migration, generic model chooser, arbitrary prompt API, reusable approval engine, ACP/MCP integration, daemon IPC, remote execution, provider abstraction, primary-checkout mutation, PR/push/merge automation, or automatic landing.
The T079-only experimental initializer is justified by a concrete upstream protocol requirement: explicit environments=[], runtimeWorkspaceRoots=[], dynamicTools=[], and selectedCapabilityRoots=[] are needed to make the first connected proof fail closed rather than inherit default environment/capability surfaces. The normal T077 initializer remains unchanged in behavior.
No further extraction/generalization is required before the first bounded connected proof. Persistence is not required to satisfy T079 provenance because the receipt binds the supplied Winds session id to the returned native thread/turn identities without conflating those namespaces.

@coderabbitai review Please perform a fresh independent review of exact head T079 is the first bounded real-Codex proof surface, but the live proof has NOT run yet. Please focus on material correctness, protocol compatibility, fail-closed authority, environment/MCP/tool isolation, process cleanup/ownership, provenance separation, and any path that could mutate the primary checkout or widen permissions. Do not infer verification/acceptance from model output. Report all material findings on this exact head. |

High-Level Assessment

Fresh review of the supplied T079 diff identifies three material findings: finding 1 — Unknown runtime notifications are not rejected (high)
Location: Recommendation: Replace the blacklist with an explicit allowlist of the exact notification methods and item types required for this proof; reject every unknown method/type, including notifications with unexpected parameter shapes. finding 2 — Effective-config validation is an incomplete allowlist (high)
Location: Recommendation: Validate the complete App Server effective-config schema/version and require an explicitly empty or disabled configuration, rejecting unknown keys and unexpected value shapes. If the API cannot provide a complete authoritative config, fail the proof rather than relying on selected fields. finding 3 — Spawned Codex can be leaked on setup failure (medium)After Location: Recommendation: Put child ownership under an RAII cleanup guard immediately after spawn, or explicitly kill/reap on every subsequent setup failure; separately remove the temporary root on all failure paths where it remains unchanged. The bounded prompt, fixed request construction, approval decline behavior, empty workspace roots, read-only/no-network request fields, identity revalidation, transcript limits, and direct-child cleanup on the normal proof path otherwise look directionally sound. The ignored live proof remains pending, and these issues should be addressed before treating T079 as a completed safety proof. |

The reader thread enforces the per-frame cap and then pushes into an unbounded channel.

--versionstdout while the child runs, not after it exits.The function polls
try_waitto completion before it reads the piped stdout. If the child writes more than the pipe buffer holds, the child blocks on write, never exits, and the loop reports "T079 Codex --version exceeded bounded timeout". The real cause is the unread pipe. The bound keeps this safe, but the error text becomes misleading.Read the bounded stdout into the buffer first, then wait for exit and check the status. That keeps the same byte cap and the same timeout semantics.

including UTF-8 conversion, process spawn, and missing stdin/stdout handles.
Update the setup flow around Command::new and the child stdio extraction to

while preserving the existing cleanup behavior after the test runs.
- Around line 890-921: Update the test function

removal of root regardless of assertion or validation failure, using
unconditional cleanup while preserving the existing sha256 identity assertions.
- Around line 97-119: Update validate_effective_config to inspect flattened and
camelCase effective-config fields, rejecting any unsupported field with a
meaningful value rather than checking only the seven known snake_case keys.
Preserve acceptance of empty or absent fields, and add coverage for active
mcpServers and an active unknown flattened field.

Author correctness / safety / evidence-integrity + Ponytail/YAGNI review for exact head 17c5344ad9c45bbc2c524df275608f40ece9d4b5 against canonical base 06e515471cf91a0f1d5b257d6e9820096d9a0197.
Facts checked:
- PR scope remains exactly three repository paths:
specs/006-agentic-terminal-local-delegation-control-plane/tasks.md,src/agentic_codex.rs, andsrc/t079_codex_connected_tests.rs; all are T079-authorized paths/scope. - The repair after
eb5a951d...changes only the T079 test/proof harness. It adds no dependency, migration, daemon, service, public protocol, MCP surface, primary-checkout mutation path, credential automation, or landing authority. CODEX_HOMEis now bound through an already-open directory descriptor and child inheritance is explicit; mutation/config-surface evidence remains fail-closed through proof reconciliation.- Only an
agentMessagewith exactphase=final_answercan populate the structured result; commentary/null phases remain non-accepting. - After the exact terminal
turn/completed, remaining stdout is consumed under existing frame/byte/time bounds through EOF and any delayed/post-terminal frame fails closed. - The final
17c5344a...delta over3bbb9c18...is rustfmt-only and exactly matches the repository-pinned Rust 1.97.1 formatter output. - Tooling PR #82 was isolated from
main, restored the canonical workflow, and was closed unmerged; none of its temporary workflow authority exists in PR #80.
Ponytail/YAGNI: the repair reuses std/libc, existing process/protocol primitives, existing bounds, and one test-only concrete Codex path. No generic watcher/runtime abstraction or new dependency is introduced. The extra handle/watch/drain logic is directly required by the three material safety findings and cannot be deleted without reopening those fail-closed gaps.
Author verdict on this exact head: no unresolved material correctness, safety, evidence-integrity, scope, or YAGNI finding identified. This is author evidence only and does not replace the required fresh independent exact-head review, deterministic gates, founder authorization for the one-shot proof, or separate landing decision.

When a same-user process creates a blocked configuration file after this post-spawn poll, Codex can open and act on that configuration before the next assert_stable() call, which does not occur until after config/read returns. The inotify event eventually rejects the proof, but it does not prevent unreviewed startup settings or side effects from running first. Fresh evidence relative to the prior finding is that the repair is a nonblocking retrospective poll rather than a mechanism that holds configuration absence through Codex's state/config open.

Accepted as material and blocking. The current exact head remains unchanged, so no connected proof will be launched. The repair must establish a preventive fail-closed boundary that makes root configuration creation impossible during startup for the governed threat model; point-in-time rechecks are insufficient. Fresh exact-head deterministic qualification and review will be required after the repair.

@codex fix this now on the existing PR branch. Implement the accepted preventive Linux/WSL2 fail-closed boundary for the root CODEX_HOME configuration-creation race, add deterministic regression coverage, and commit it. Do not run the ignored connected proof, do not merge, do not read/copy credentials or config contents, and do not broaden authority. Starting exact head is 17c5344ad9c45bbc2c524df275608f40ece9d4b5.

Reclassification after rereading the canonical Spec 006 threat model: this concern assumes hostile same-user/host isolation that T079 does not claim. Spec 006 explicitly treats direct host access that can bypass Winds as weaker enforcement that must be reported truthfully, and an OS sandbox/platform is outside this initial program scope. T079 requires rejecting pre-existing blocked configuration surfaces before launch; it does not add a concurrent hostile host actor. Expanding this slice into mount/fanotify/immutable-directory/kernel isolation would broaden scope and violate the task’s simplicity/YAGNI gate. I am therefore classifying this finding as NON_MATERIAL / OUT_OF_CONTRACT for T079 while retaining truthful enforcement labeling.

When the test runner has TMPDIR set to the primary checkout or one of its descendants, this allowlist passes that writable path to both real Codex launches without the containment validation applied to CODEX_HOME and the disposable root. Any Codex or dependency temp-file creation can therefore mutate the primary checkout despite the T079 safety boundary; omit TMPDIR or canonicalize and reject checkout-contained values before inheriting it.

Accepted as material and blocking. The child must not inherit an unchecked TMPDIR; the repair must ensure child temporary-file placement cannot resolve inside the primary checkout, with focused deterministic regression coverage. No connected proof will be launched on the current head.

@codex fix this now on the existing PR branch.

Resolved in exact repair commit be28495628bc0e00f45a225ed718869d71195b94.
The non-Windows child environment allowlist is now empty, so host TMPDIR is not reintroduced after env_clear(). The existing explicit-environment regression now also asserts that TMPDIR is absent on non-Windows platforms.
Exact repair delta is one commit from 17c5344ad9c45bbc2c524df275608f40ece9d4b5; exact-head CI and independent requalification remain pending, so this reply records the code repair rather than claiming qualification.

When App Server returns a thread/start result whose thread.cwd differs from the requested disposable root, this validator still accepts it because it checks ephemerality, policy, sandbox, roots, and instructions but never compares the returned cwd with the expected canonical path. The receipt can consequently claim exact bounded thread provenance without proving which workspace the native thread was actually created against; pass the expected cwd into this validation and require an exact match.

Accepted as material and blocking. The repair must require the native thread.cwd returned by thread/start to exactly match the canonical disposable proof root and must add a mismatch regression. The current exact head is not eligible for connected execution.

@codex fix this now on the existing PR branch. Require the returned native thread.cwd to exactly equal the canonical disposable proof root, add an explicit mismatch regression, and commit with the other accepted T079 repairs. Do not run the ignored connected proof or merge. Starting exact head is 17c5344ad9c45bbc2c524df275608f40ece9d4b5.

Resolved in exact repair commit be28495628bc0e00f45a225ed718869d71195b94.
validate_thread_start_result now receives the canonical expected disposable cwd and rejects the thread/start response unless native thread.cwd exactly matches it. The connected proof passes its exact canonical disposable root into that validator, and focused regression coverage now includes an explicit mismatched-cwd rejection case.
Exact-head CI and independent requalification remain pending; this reply records the implementation repair without claiming qualification.

T079 live continuation checkpoint for exact candidate Current exact-head deterministic qualification:
Fresh founder authorization for the one-shot retry was received in the active execution session as a direct approval of the immediately preceding exact-SHA authorization request for A non-launching local preflight was then performed in the currently available execution environment. Facts observed: The T079 authority-hardening amendment requires a pre-existing native Codex binary plus a pre-existing isolated already-authenticated Current truthful state: Do not interpret this checkpoint as PASS, proof execution, canonical closure, or merge authorization. Re-fetch live head/main and repeat the non-launching preflight before any later connected execution. Any candidate movement invalidates this exact-SHA authorization and exact-head evidence applicability. |

@codex address that feedback Please repair only the three material review findings on exact head
Add focused deterministic regression coverage for each repair. Keep the diff T079-only, add no dependencies or migrations, do not run the ignored real connected proof, do not merge, do not change authorization state, and do not claim T079 closed. Run only deterministic validation available to you and leave exact-head evidence for fresh review. |

T079 live review reconciliation checkpointThis checkpoint supersedes the PR body's earlier Accepted blocking findings on this exact head:
A bounded repair request has been issued with explicit instructions not to run the ignored connected proof, not to merge, not to broaden authority, and to add deterministic regression coverage. No repair commit has landed as of this checkpoint. Any repair commit changes the exact candidate SHA and invalidates the current exact-head qualification/review and the existing exact-SHA connected-proof authorization. The new head must be re-qualified and, where required by the task text, receive fresh exact-SHA authorization before any connected execution. The current execution environment also independently lacks the required pre-existing native |

T079 execution/tooling blocker checkpointLive state remains pinned to exact head The three accepted material findings remain unresolved. A safe repair was not committed from the current execution environment because:
Reconstructing and replacing the complete file without a checkout/compile/diff validation path would violate the repository's exact-candidate evidence and safety requirements. No such unvalidated replacement was pushed. Security reconciliation also rejects a child-only Landlock/write-denial repair for the CODEX_HOME finding: the reported race is an external same-user process adding a blocked root configuration after the last poll. Restricting only the Codex child does not stop that external namespace mutation from becoming readable startup configuration. The eventual repair must provide Codex a startup/config-resolution namespace in which the blocked root configuration names remain unavailable despite concurrent mutation of the source CODEX_HOME, without reading or copying credential/config contents. This is a fail-closed execution checkpoint, not PASS/COMPLETE/MERGED evidence. |

@TheHalfMoon, I cannot directly modify or commit to the PR branch. I prepared a constrained change plan for the exact formatter-only edit. It excludes tests, the ignored connected proof, and merge actions.
- Update only
src/t079_codex_connected_tests.rs. - Apply the specified
cargo fmtlayout tovalidate_thread_start_result. - Do not change semantics, other lines, or other files.
- Do not run the ignored connected proof.
- Commit only this formatter change.

AUTHOR_T079_EXACT_HEAD_REVIEW
Exact head: 9f3c2c1a43ddfcbd027524d9f1a7fe09e0086651
Canonical base: 06e515471cf91a0f1d5b257d6e9820096d9a0197
Semantic parent: be28495628bc0e00f45a225ed718869d71195b94
Author correctness / safety / evidence-integrity review completed against the live exact head and the current Spec 006 / T079 authority chain.
Findings:
- The semantic parent removes inherited
TMPDIRfrom the desktop-terminal launch environment, preventing the fixture-controlled temporary root from being inherited as host evidence provenance. - The connected parity proof now requires the App Server returned
thread.cwdto equal the repository checkout root before accepting the run, preventing a same-user host session rooted elsewhere from satisfying the checkout-binding claim. - The exact-head delta from
be284956...to9f3c2c1...is rustfmt-only and does not weaken either provenance control. - Exact-head deterministic workflows are green:
release-candidate#593,windows-terminal#538, andquality#835 all completed successfully. - No force-push, rebase, destructive history rewrite, governance bypass, Codex installation, Codex authentication, credential copying, automated login/terms acceptance, or synthetic connected proof was performed in this continuation.
- The governed local preflight still cannot execute the real bounded Codex App Server proof in this execution environment: no
codexbinary is available and no local Winds checkout is available. This remainsBLOCKED_UNVERIFIABLE; no connected-runtime acceptance is claimed. - This author review is not independent approval authority and does not authorize merge or canonical closure.
Author disposition on this exact head: no new material correctness, safety, evidence-integrity, or scope defect identified from the current candidate delta. The real bounded Codex App Server proof and independent-review requirements remain separate gates.

PONYTAIL_T079_EXACT_HEAD_YAGNI_REVIEW
Exact head: 9f3c2c1a43ddfcbd027524d9f1a7fe09e0086651
Canonical base: 06e515471cf91a0f1d5b257d6e9820096d9a0197
Ponytail / YAGNI review completed on the live candidate.
Minimum-surface findings:
- The PR remains bounded to three T079-authorized repository paths:
specs/006-agentic-terminal-local-delegation-control-plane/tasks.md,src/agentic_codex.rs, andsrc/t079_codex_connected_tests.rs. - The latest semantic repair is confined to the T079 connected-proof harness and directly addresses two evidence-provenance findings: inherited temporary-root contamination and wrong-checkout thread provenance.
- The exact-head commit is formatting-only. It introduces no new dependency, migration, service, daemon, public protocol, provider abstraction, generic agent layer, landing automation, or expanded credential/authentication surface.
- No additional abstraction or extraction is justified by the current repair. Removing either provenance check would reopen a concrete evidence-integrity gap.
- The connected proof remains intentionally fail-closed when a real governed Codex App Server runtime cannot be executed; no fallback or mock is treated as equivalent proof.
YAGNI disposition on this exact head: no required scope removal or speculative implementation identified.

LIVE_CONTINUATION_EVIDENCE_AND_FOUNDER_AUTHORIZATION Canonical base reverified: Exact-head repository evidence:
Governed execution-environment preflight was repeated without reading credential/config contents or changing authentication state: Founder authorization is explicitly recorded for this exact candidate: if and only if the canonical T079 preflight later proves that the already-installed/revalidated real local Codex App Server and exact Winds candidate checkout are available without installing Codex, changing authentication, copying credentials/configuration, accepting terms, substituting CI/remote execution, or weakening the reviewed safety boundary, the single bounded T079 connected proof is authorized on exact head This authorization does not convert absent runtime evidence into proof, does not waive independent review, and does not authorize a merge before every T079 acceptance gate succeeds. Once all canonical gates are satisfied, the founder has authorized ordinary guarded landing/closeout work and continuation to the next dependency-satisfied task. |

This environment therefore cannot produce the real bounded local Codex App Server round-trip evidence. Do not manufacture that proof by installing Codex, authenticating Codex, copying credentials/configuration, automating login or terms acceptance, substituting remote/CI execution, cloning a checkout solely to manufacture proof, or weakening governance.
The founder has already authorized one exact-head bounded proof conditionally on a governed preflight finding a legitimate pre-existing Codex runtime and exact Winds checkout. That authorization does not waive any proof, review, scope, or merge gate and becomes stale if the candidate head moves.
