When a patch intentionally removes a previously supported input—such as a documented breaking change or deprecation cleanup—the base source will necessarily prove that the control used to be supported, but that alone does not prove the patch is defective. This instruction unconditionally requires revise even when the removal is authorized, documented, and fully tested, preventing the otherwise valid merge/human_review_required outcome for public-contract changes. Require evidence that the control must remain supported, rather than treating prior support itself as a failed boundary.

For versioned or event-sourced systems whose replay contract deliberately evaluates the principal, resource, and policy version recorded with the event, the current governing policy can change while the saved authority remains the correct input. This rule nevertheless requires reclassification against the current values or proof that they cannot change, so a correct deterministic replay implementation can only be reported as unresolved or defective. Allow an authoritative contract to establish that the recorded snapshot is itself the governing decision context instead of assuming every mutable policy must be refreshed.

When either skill document is rewritten with semantically equivalent language, these toContain assertions fail even though the assessment contract remains intact, creating brittle maintenance coupling between tests and prose. The scoped test guidance explicitly says to avoid tests of exact Markdown wording, so cover the intended behavior or a structured invariant instead of pinning these sentences.

When the accepted commit_range input was constructed with the wrong base, or a provider returns a stale comparison, the comparison can be wrong even though the patch did not cause that failure. This directive nevertheless forces failureAttribution: patch_caused and, once applicability is known, revise, producing a defect verdict against the author instead of requesting a corrected immutable artifact as step 1 requires. Distinguish patch pollution from an externally selected or stale comparison before assigning patch-caused attribution.

When authoritative evidence permits an intentional contract narrowing, line 53 says the boundary must not be marked contradicted merely because the base supported the removed control, but this summary still allows the base source's proof of that newly rejected control to establish a contradiction. Because a contradicted boundary drives revise, assessors can still reject an authorized breaking change; align this condition with the earlier requirement for a current governing contract or required caller. Fresh evidence in this version is this newly changed summary clause, which retains the behavior despite the detailed narrowing rule being corrected.

When a comparison includes an unrelated but otherwise correct runtime change, this sentence mandates revise, but semantic_errors() accepts that recommendation only when there is a critical regression likelihood, a contradicted boundary, or failed validation (validate_patch_risk_assessment.py, lines 87-93 and 209-210). A scope-only mismatch has none of those, so the prescribed validator rejects the recommendation the skill requires; represent comparison/scope mismatch as revision evidence or use a recommendation supported by the output contract.

When --create-pr is used with a single imported Linear issue, directPatchIdentifier returns its identifier (for example, SEC-123), and this call uses it both to derive the public branch name and, below, in the PR introduction. That exposes a private issue identifier through codex-security/patch-SEC-123 and the PR body; use the opaque digest and a generic introduction instead.

When --assess-patch-risk and --create-pr are combined, this model-generated summary is inserted into the body and published by gh pr create without any user inspection. safePatchReport only handles limited credential-like patterns, so a summary containing a customer name, repository URL, scan finding, or undisclosed vulnerability is still published publicly; require an explicit review/confirmation step or keep generated report text out of automatic PR bodies.

When a literal or Linear patch --create-pr run succeeds, this new path supplies only a generated introductory sentence (plus an optional risk summary) to createPatchPullRequest, whose gh pr create --body call never loads .github/PULL_REQUEST_TEMPLATE.md. Every supplied-issue PR therefore omits the required Summary, Changes, Testing, Risk and rollout, and disclosure-attestation sections; start these bodies from the repository template and complete its sections before publication.

There was a problem hiding this comment.
When patch ISSUE --create-pr runs in an initialized repository with no commits, this unconditional read-tree HEAD fails before the patcher starts because HEAD does not yet resolve. The existing publication code already supports an absent head by using an empty index, so the newly supported supplied-issue path should likewise use read-tree --empty when no head exists; otherwise this advertised --create-pr flow works for saved findings but not for literal or imported issues in an unborn repository.

When a literal or imported-issue patch edits files but finishes with a natural-language blocked or failed-verification outcome, the app-server turn can still return transport status 0; unlike the saved-finding path, this path neither requests nor parses a structured patch status before entering publication. It therefore opens a draft PR containing the partial changes solely because the Codex process completed successfully, so require an explicit verified outcome rather than treating exitCode === 0 as verification.

When patch ISSUE --create-pr is invoked from a Git subdirectory without an optional review, patchRepository remains that subdirectory, but this tree-to-tree diff returns repository-root-relative names. I checked git diff -h, which describes --relative as the option that, when run from a subdirectory, excludes outside changes and shows relative paths; it is absent here. The returned names are later passed as ordinary git add pathspecs from the subdirectory, so a change such as root path sub/file.ts is looked up as sub/sub/file.ts and publication fails or stages the wrong same-named path; resolve the Git top level or consistently convert the names to the publication working directory.

The release highlight calls --assess-patch-risk an “advisory assessment,” but the implemented behavior and sdk/typescript/README.md lines 882-887 say that every non-merge recommendation fails the selected review and prevents automatic publication. Users or automation relying on these release notes can therefore enable what appears to be reporting-only behavior and unexpectedly have otherwise completed patches rejected; describe the flag as an opt-in gating review here as well.

Summary
Strengthen patch-risk review guidance for comparison scope, contract changes, and reused authority. Integrate the verified patch-review stack with current main while preserving this PR's configured base.
Changes
reviseunder the existing output contract.0.1.84and verify cache replacement from earlier versions.Testing
Current patch-risk contract suite: 17 passed, including rejection of an evidence-free scope revision and acceptance once failed scope validation is recorded.
Six-file CLI/review/runtime integration run at seed 658: 525 passed, 14 platform skips, zero failures.
Four real bundled Codex cache upgrades from
0.1.37,0.1.60,0.1.81, and0.1.82to0.1.84passed, checking installed guidance/schema/validator bytes and preserved credentials.Types/generated-model freshness, formatting, build, Ruff, Python 3.10 grammar, static package validation, and full installed-package smoke: passed.
Windows shard routing: all 97 shared test files assigned exactly once across eight shards; the existing fifteen-minute timeout is unchanged.
Native Windows/Linux, live model behavior, full cross-platform suite and current-head CI were not run locally. CI is left for the second pass.
Final main refresh (
fd98a90): package 0.1.21 includes the MCP launcher-permission fix; SDK implementation and bundled payload are unchanged. Types/model generation, formatting, build, 28 focused tests, static artifact verification and full installed-package smoke passed, including MCP initialization. CI was not awaited.Risk and rollout
The configured parent PR was closed externally. Its remote branch and this PR's base setting are unchanged; the verified integration is carried only into this open child. This diff therefore includes stack integration as well as the additional guidance and is not a standalone two-file documentation change.
The stack preserves its opt-in validated
--assess-patch-riskgate, which prevents automatic publication for non-merge recommendations, pluspatch --pythoninterpreter selection. This differs from main's advisory assessment behavior; no additional flags are introduced by this cleanup. Guidance tests verify valid structured outputs, not model judgment. Native Windows timing still needs CI verification.Public disclosure review
Historical commit contact metadata and automated restricted settings links remain in the existing PR history, so the second attestation stays unchecked. New fixtures are synthetic; new commits use GitHub noreply metadata.
