Summary

Prevent the central OpenCode coverage image from installing native fuzz-engine toolchains that the generic coverage job never executes.

  • classify the exact file name requirements-atheris.txt as a native fuzz-engine lock;
  • exclude it from trusted-base generic coverage materialization at any module depth;
  • continue materializing hash-pinned property and regression locks, including similarly named nonexact files;
  • preserve exact-base Git reads, shared credential-redacting failure diagnostics, hash enforcement, PR-input isolation, deterministic output, symlink rejection, and malformed-tree failure;
  • verify the boundary with a real temporary-Git integration fixture and exact-name classifier contract;
  • execute the regression from the permanent Python 3.10/3.14 diagnostics workflow;
  • retain 100% statement, branch, and docstring gates for the changed central Python surface;
  • add APA 7 doctoring and changelog evidence.

Stack order and focused scope

Current exact head: 66d5a26498503361aa814e5be742ac8c6335246b.

This branch is built directly on exact OpenCode diagnostics and Strix hardening prerequisite head 4d076f636b6de5043e8501e93c06ed0a8c896eb3 from #759. The child diff contains the exact-name materializer change, its realistic regression, the permanent diagnostics workflow registration, design, updated implementation plan, APA 7 doctoring, and changelog.

Temporary exact-stack run 30990609972 caught a real integration regression on predecessor head 050cb25e3a7c317503c5221f095281cb9400c780: the earlier file replacement had removed #759’s shared _publish_coverage_failure_summary call, causing both Python failure-diagnostic tests to produce no GITHUB_OUTPUT file even though raw coverage remained 100%. Head 54591186557d8251f9c2967c11cd98ff926d6464 repaired the code by applying only the classifier to the current #759 materializer and made the permanent diagnostics workflow execute the new regression; run 30990945724 passed both Python 3.10 and 3.14 jobs. Current head additionally removes stale #76 integration guidance and explicitly preserves the diagnostic workflow in the plan.

A temporary Draft verification PR was closed without merge after every direct workflow succeeded on this exact current head:

  • OpenCode Coverage Diagnostics CI 30991153826;
  • Python Security 30991153764;
  • Security Scan 30991153704;
  • CodeQL 30991153852;
  • SAST Semgrep 30991153727;
  • OSV 30991154176;
  • Secret Scan 30991153720;
  • SBOM 30991153841;
  • Scorecard 30991153859.

Required order:

  1. merge fix(opencode-review): surface exact coverage setup failures #759 after its exact-head independent approval completes;
  2. retarget this PR to the resulting main without changing its reviewed coverage behavior;
  3. rerun every exact-head central check and current-head review;
  4. merge without administrative bypass;
  5. re-dispatch contextual-orchestrator ruleset pin 문서 갱신 #96 coverage and independent review evidence.

Focused security PR #776 and older provider transport PR #76 were closed unmerged as superseded by #759 and #96 respectively, eliminating duplicate ownership.

Security and review boundary

This PR reduces the dependency closure entering the networked generic coverage image. It does not weaken --require-hashes, remove bounded sanitized failure evidence, change dedicated Fuzz workflows, accept pull-request-mutated dependency metadata, suppress selected application or test import failures, or change OpenCode, Noema, Strix, NVIDIA NIM, and reviewer credential names or scopes.

Buyer and organization impact

A repository can repair an interpreter-specific native fuzz lock without the existing protected base first breaking unrelated source-coverage evidence. Dedicated repository fuzzing remains an independent required gate, and exact setup failures remain visible to reviewers.

Validation gate

Merge only after exact-head focused and full central tests, 100% statement and branch coverage, docstrings, compile/static checks, Python Security, Security Scan, CodeQL, Semgrep, OSV, Secret Scan, SBOM, Scorecard, OpenCode, Noema, CodeRabbit, independent approval, and every branch-protection rule pass.

Closes #762.
Refs #759 and ContextualWisdomLab/contextual-orchestrator#96.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

  • Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

  • Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

  • Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

  • Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

  • Result: REQUEST_CHANGES

  • Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head 931fe3b7f296d7624e494f4c2f934873433d5be8.

Pull request overview

OpenCode reviewed the current-head bounded evidence and requested changes before merge.

Findings

1. P1 scripts/ci/materialize_base_python_requirements.py:24 - Core changed surface (exact-name native fuzz-engine lock classifier and its fixture) is not inspectable in the trusted evidence - fail-closed until hunks are supplied

  • Problem: The PR's central behavior is a new exact-name classifier that excludes requirements-atheris.txt from trusted-base generic coverage materialization at any module depth while keeping hash-pinned property/regression locks eligible. The trusted current-head evidence for this run contains no diff hunks for scripts/ci/materialize_base_python_requirements.py or tests/test_coverage_native_fuzz_lock_boundary.py: the Focused changed hunks section of bounded-review-evidence.md truncates at the plan document with the marker '[Prompt evidence truncated after 12000 of 23673 bytes ...]' (bounded-review-evidence.md:991-993), and the precomputed CodeGraph changed-scope exploration for this PR's changed files surfaced only unrelated sources (scripts/ci/r_coverage_peer_gate.py, tests/test_noema_review_gate.py, tests/test_opencode_existing_approval_gate.py) and reports 'no covering tests found' for materialize at scripts/ci/materialize_base_python_requirements.py:214. Direct reads of /home/runner/work/_temp/opencode-pr-head are denied by this runtime's permission policy. Because materialize is the org-wide coverage dependency materializer (blast radius: every repository's coverage evidence), approval requires affirmative source evidence of the classifier's exact-name (non-substring) matching, path-independent placement in the blob-selection flow, and fail-closed behavior on malformed Git trees, symlinks, and unpinned lines; that evidence is absent in this run. The workflow wiring (paths filters, pytest step with --cov-branch --cov-fail-under=100, compileall) and the Coverage execution evidence Result: PASS are present and consistent, but they do not substitute for the classifier source itself, which the review contract requires before approving material script changes.
  • Root cause: Evidence-generation truncation cut the Focused changed hunks before the materializer/test diffs, and this run's CodeGraph changed-scope exploration did not cover the changed files' source or test reachability (it returned unrelated files and 'no covering tests found' for materialize at :214).
  • Fix: Supply the full current-head diff hunks for scripts/ci/materialize_base_python_requirements.py and tests/test_coverage_native_fuzz_lock_boundary.py in the trusted evidence (or make the head checkout readable to reviewers) and re-run the CodeGraph changed-scope exploration for these files so the classifier predicate, its call site inside materialize, and the fixture assertions (generated manifest contains only requirements-property.txt and requirements-fuzz-regression.txt; exact-name exclusion does not match substrings or directory names) are source-backed. Also surface the new identifier names so the two-word naming and reserved-word conventions can be checked.
  • Regression test: python3 -m pytest tests/test_coverage_native_fuzz_lock_boundary.py tests/test_materialize_base_python_requirements.py -q; plus the diagnostics workflow gate python -m pytest tests/test_coverage_native_fuzz_lock_boundary.py --cov=scripts.ci.materialize_base_python_requirements --cov-branch --cov-fail-under=100 -q
  • Suggested diff: posted in this finding's inline review thread.

Summary

PR #763 (fix(coverage): keep native fuzz locks out of generic images). Changed-file evidence inspected: .github/workflows/opencode-coverage-diagnostics-ci.yml (pull_request/push paths filters, 'Run diagnostics and lock contracts with full branch coverage' pytest step, 'Compile changed Python surfaces' step), CHANGELOG.md, docs/doctoring/coverage-native-fuzz-lock-boundary.md, docs/superpowers/plans/2026-08-05-coverage-native-fuzz-lock-boundary.md, docs/superpowers/specs/2026-08-05-coverage-native-fuzz-lock-boundary-design.md. Blocking: the two core changed files scripts/ci/materialize_base_python_requirements.py and tests/test_coverage_native_fuzz_lock_boundary.py have no hunks in the trusted evidence (Focused changed hunks truncates at the plan doc, bounded-review-evidence.md:991-993), the CodeGraph changed-scope exploration for these changed files surfaced only unrelated sources (r_coverage_peer_gate.py, test_noema_review_gate.py, test_opencode_existing_approval_gate.py) and reports 'no covering tests found' for materialize at scripts/ci/materialize_base_python_requirements.py:214, and direct reads of /home/runner/work/_temp/opencode-pr-head are denied in this runtime - the exact-name Atheris-lock classifier semantics therefore cannot be affirmatively verified, so this review fails closed (REQUEST_CHANGES). DAG: flowchart LR with quoted labels mapping opencode-coverage-diagnostics-ci.yml -> materialize_base_python_requirements.py materialize:214 -> exact-name native fuzz-engine lock classifier (hunks absent from evidence) -> generic coverage image lock set; fixture test -> classifier; dedicated Fuzz workflow (unchanged) as the parallel execution path; head-flow from workflow hunks, classifier internals unverified. Approval sufficiency: NOT met - core changed surface uninspectable; positive evidence for changed-file behavior required by contract. Verification posture: Coverage execution evidence Result: PASS (supported repository test suites passed); docstring gates passed or advisory; no OPENCODE_EXECUTION_RECEIPT lines exist in the evidence, so no per-run tool receipt is citable (execution limitation). Linter/static: repo lint_commands cover hadolint/npm audit/pip_audit/bandit/trivy; diagnostics workflow runs compileall on changed surfaces including the new test. TDD/regression: fixture is described (real temp-Git base with fuzz/requirements-atheris.txt, fuzz/requirements-property.txt, services/example_service/requirements-fuzz-regression.txt; manifest must contain only property/regression locks; second contract for exact-name non-substring classification) but fixture source is not in the evidence. Coverage: trusted Coverage execution evidence Result: PASS - supported repository test suites passed (diagnostics workflow enforces --cov-branch --cov-fail-under=100 on scripts.ci.materialize_base_python_requirements). Docstring coverage: configured repository docstring gates passed or advisory per Coverage execution evidence. DAG: see mermaid in this summary (head flow; classifier internals unverified). PoC/execution: none - no execution receipts present. DDD/domain: lock-role classification (native fuzz engine vs property/regression) is a clear domain rule, documented in the doctoring record and changelog. CDD/context: change sits at the org-wide coverage materialization trust boundary; docs/changelog/plan/spec are mutually consistent with PR intent. Similar issues: repo history shows the materializer evolved through evidence-backed changes (#657 content-based discovery, #661, #668); this PR follows that pattern. Claim/concept check: docs claim exact-name, path-independent exclusion with substring/directory-name regression contract and unchanged hash-pinning/immutable-base trust - unverifiable from evidence (docs are PR-controlled text). Standards search: Keep a Changelog 1.1.0 and SemVer 2.0.0 links in CHANGELOG.md; APA 7 references in the doctoring record; no contradiction found in evidenced content. Compatibility/convention: workflow naming/paths follow sibling entries; classifier identifiers inside the uninspectable file cannot be naming/reserved-word reviewed. Breaking-change/backcompat: exclusion changes which locks enter generic coverage images; dedicated Fuzz workflows unchanged per docs; no public API surface changed. Implementation completeness: unverifiable for the classifier; all doc artifacts (changelog, doctoring, plan, spec) present. Performance: exclusion reduces image installs; no measurable regression evidenced or expected. Developer experience: DX surface = coverage-diagnostics workflow; new fixture is wired into triggers, pytest (with branch-coverage gate), and compileall, matching sibling test wiring. User experience: UX surface = repository coverage evidence flow; policy-only change, no interactive UI; docs state application/test import failures remain fail-closed (not suppressed). Visual/DOM: non-web change; interaction surface reviewed = workflow config, review-comment output, and docs. Accessibility/i18n: not applicable (non-web); docs English-only, consistent with repository. Supply-chain/license: exclusion reduces installed native artifacts; hash-pinning and exact-base reads preserved per doctoring record - no evidence of weakening. Packaging: pyproject.toml (requires-python >=3.10) defines test/coverage/docstring commands; scripts/ci package covered by pytest per coverage evidence. Security/privacy: no secrets/authz surface changed; trust-boundary invariants (immutable base, malformed-tree/symlink fail-closed) documented as unchanged but classifier internals unverified. Blocking finding: P1 scripts/ci/materialize_base_python_requirements.py:24 - evidence gap for the core classifier; supply the materializer and fixture diff hunks (or a readable head checkout) for re-review.

Root-cause repair at exact head 99eabb1ae0995f0bc17fa3c20862a527e24f7be9:

The prior OpenCode coverage run failed before evaluating this PR’s native-fuzz lock behavior because the protected-base scheduled-security-scan.yml mixed CodeQL Action revisions (v4.37.0 for init/analyze and v4.37.4 for upload-sarif). The current head aligns all three phases to the immutable v4.37.5 commit d1ba80a13dd99fba24a470575428917156a28b43.

I reproduced the failure from the exact coverage-source artifact (tests/test_codeql_pr_workflow_contract.py::test_codeql_action_steps_use_one_version_per_workflow) and verified that the focused native-fuzz lock tests themselves pass. No coverage, security, dependency, reviewer, or credential gate was weakened. Fresh exact-head checks and independent review remain required.

The prior CHANGES_REQUESTED review is bound to superseded head 931fe3b7f296d7624e494f4c2f934873433d5be8; its coverage failure was reproduced from the archived merge tree as a mixed CodeQL Action revision in scheduled-security-scan.yml. The current head aligns init, analyze, and upload-sarif on immutable v4.37.5 SHA d1ba80a13dd99fba24a470575428917156a28b43, and all exact-head direct workflows plus CodeRabbit status are successful. Reverify full Python coverage/docstring evidence, exact-name native-fuzz exclusion, immutable-base/hash/symlink boundaries, dedicated fuzz separation, Strix snapshot, changelog, and APA 7 doctoring. Submit APPROVE only for this exact head if no blocker remains.

seonghobae dismissed opencode-agent[bot]’s stale review August 5, 2026 02:53

The requested-changes review targets superseded head 931fe3b. Current head 99eabb1 adds the exact scheduled-CodeQL revision repair and all direct security/supply-chain workflows pass. A fresh exact-current-head coverage review is required; dismissal is not approval.

@coderabbitai review

Please review exact current head 99eabb1ae0995f0bc17fa3c20862a527e24f7be9. Verify the exact-name native-fuzz lock classifier, nested-module behavior, continued inclusion of similarly named nonexact locks, immutable-base Git reads, symlink and malformed-tree fail-closed behavior, real temporary-Git integration fixture, secure Strix dependency floor, exact CodeQL revision alignment, and APA 7th doctoring. Do not reuse evidence from 931fe3b7f296d7624e494f4c2f934873433d5be8.

@opencode-agent Please rerun complete exact-head test, coverage, and docstring evidence for 99eabb1ae0995f0bc17fa3c20862a527e24f7be9. The prior requested-changes review was dismissed only because it targets the previous head.

@cwl-noema-review Please independently review this exact current head after all protected gates succeed.

@seonghobae Approved for exact head e4a704c25761de68b288d8c3b17d09dd395f7a9b.

I found no current actionable blocker.

Verified items:

  • The classifier excludes only the exact basename requirements-atheris.txt.
  • Nested hash-pinned property and regression locks remain eligible.
  • Materialization reads Git tree entries and blobs from the validated 40-character base SHA.
  • The materializer rejects malformed tree entries and symlink output directories.
  • The output order is deterministic because source paths are sorted before materialization.
  • The temporary-Git fixture verifies nested Atheris exclusion and property/regression lock retention.
  • No dedicated Fuzz workflow changed in this PR.
  • CodeQL init, analyze, and upload-SARIF use immutable revision d1ba80a13dd99fba24a470575428917156a28b43.
  • Strix requirements and hashes select aiohttp==3.14.3, cryptography==50.0.0, and pyopenssl==26.4.0.
  • CHANGELOG.md and the APA 7 doctoring record document the boundary and rollback condition.
  • GitHub reports current-head success for coverage, OpenCode review, CodeQL, Semgrep, secret scan, OSV, Scorecard, SBOM, Strix, dependency review, pip-audit, and Trivy.

The sandbox cannot execute repository tests. The successful current-head coverage-evidence check provides the CI evidence for the required coverage and docstring gates.

Current-head blocker diagnosis for ae20bc30ec3b26d996ceb665a64ac7b5722e047e: the focused native-fuzz-lock change itself is not the source of the failed hard gates. Python Security and Security Scan audit the complete repository and correctly found the protected-base Strix snapshots still contain aiohttp==3.14.1 (fixed in 3.14.3) and cryptography==49.0.0 (fixed in 50.0.0). This PR had intentionally restored those files to current main to keep its diff focused, so rerunning the same head cannot succeed. Safe order: merge secure central baseline #743 first, update this branch onto that exact protected main, confirm the final diff again contains only the exact requirements-atheris.txt exclusion boundary, and rerun every check/review on the new head. No failed or predecessor-head evidence is treated as approval, and no duplicate security-lock changes are added here before #743 resolves.

@seonghobae I reviewed only c2120a2bc8b7d52c100b4271a5fad17ef716ab39 against 08d83dd2c2e4ba3ff577c9c8e53442260b3b0ff9.

I found two approval blockers.

  1. The repository does not generate or enforce branch-coverage evidence.

    pyproject.toml configures statement coverage with fail_under = 100. It does not set [tool.coverage.run] branch = true.

    The effective Python command in .github/workflows/opencode-review-dispatch.yml is python3 -m coverage run -m pytest. It does not use --branch.

    Therefore, the required 100% branch-coverage evidence is not available for this head.

  2. The fallback docstring check is advisory.

    tests/test_docstrings.py is absent. The fallback in .github/workflows/opencode-review-dispatch.yml runs:

    python3 -m interrogate . || true

    This command cannot fail the coverage-evidence job. It does not enforce the configured fail-under = 100 threshold.

I also cannot approve while the exact-head strix check remains IN_PROGRESS. GitHub reported mergeStateStatus: UNSTABLE.

I verified the focused implementation boundary:

  • The exact base-to-head diff has six coverage-policy files.
  • The classifier excludes only the exact basename requirements-atheris.txt.
  • The classifier operates on PurePosixPath(path).name, so module depth does not change the result.
  • requirements-atheris-regression.txt, property locks, and regression locks remain eligible.
  • The temporary-Git fixture commits nested locks and verifies that only the property and regression locks materialize.
  • The materializer validates the 40-character base SHA, reads blobs from that immutable base, requires hashes, rejects malformed Git-tree data, rejects symlink output directories, and sorts output inputs.
  • No dedicated Fuzz workflow changes in the requested diff.
  • The changelog and APA 7 doctoring document the boundary and rollback condition.

I cannot approve this head. Enable and enforce branch coverage, make docstring coverage mandatory, and wait for the exact-head strix check to complete successfully.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

  • Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

  • Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

  • Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

  • Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

  • Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

  • Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

  • Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

  • Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

Apply the native-fuzz exact-name classifier on top of the current shared failure-summary materializer instead of replacing it with an older implementation, and make the permanent diagnostics workflow execute and compile the new realistic regression.

Review exact current head 54591186557d8251f9c2967c11cd98ff926d6464 against exact prerequisite base 4d076f636b6de5043e8501e93c06ed0a8c896eb3 only. Predecessor 050cb25e3a7c317503c5221f095281cb9400c780 failed run 30990609972 because an older materializer replacement removed the shared bounded failure-summary publisher. The repair preserves #759’s shared diagnostic path, adds only the exact-name native-fuzz classifier, and registers the realistic regression in the permanent diagnostics gate; exact run 30990945724 now succeeds. Verify nonexact lock retention, immutable-base and hash-pinned materialization, sanitized setup evidence, malformed-tree/symlink/output fail-closed behavior, dedicated Fuzz preservation, 100% statement/branch/docstring evidence, and APA 7 doctoring. Submit a formal exact-head review or actionable findings; do not reuse predecessor evidence.

@seonghobae I reviewed only 54591186557d8251f9c2967c11cd98ff926d6464 against 4d076f636b6de5043e8501e93c06ed0a8c896eb3.

I found no source-level blocker in the requested scope.

Verified items:

  • The classifier excludes only the exact basename requirements-atheris.txt.
  • Classification is path-independent because the materializer evaluates PurePosixPath(path).name.
  • The temporary-Git fixture retains nested property and regression locks.
  • The materializer validates a 40-character base SHA and reads candidate blobs from that exact base commit.
  • Hash-pinned selection remains required.
  • Existing tests retain malformed-tree rejection, non-blob handling, deterministic ordering, and output-symlink rejection.
  • The exact diff does not modify a dedicated Fuzz workflow.
  • The diagnostics workflow includes the new regression in its permanent gate.
  • Exact run 30990945724 ran on this head and succeeded.
  • That run reported 100% statement and branch coverage for scripts/ci/materialize_base_python_requirements.py.
  • That run reported 100% production docstring coverage.
  • The changelog and APA 7 doctoring document the boundary and rollback condition.

I cannot approve yet. GitHub currently reports mergeStateStatus: UNSTABLE because two current-head strix checks are still IN_PROGRESS. Wait for those checks to complete successfully, then request approval for this same head.

You are interacting with an AI system.

Remove the closed #76 rebase step, name #759 and #96 as the surviving ordered prerequisites, preserve shared failure diagnostics in the implementation task, and include the permanent diagnostics workflow in the reviewed commit scope.

Summary

APPROVE PR #763 (fix(coverage): keep native fuzz locks out of generic images) on head 66d5a26. The PR adds an exact-name classifier to scripts/ci/materialize_base_python_requirements.py (receipts at lines 24 and 39; CodeGraph shows materialize() at line 214) that excludes requirements-atheris.txt from generic coverage materialization while keeping hash-pinned property/fuzz-regression locks eligible, and wires the new fixture tests/test_coverage_native_fuzz_lock_boundary.py into .github/workflows/opencode-coverage-diagnostics-ci.yml paths filters (pull_request and push), the pytest --cov-branch --cov-fail-under=100 run, and the compileall gate. Changed-file evidence inspected: .github/workflows/opencode-coverage-diagnostics-ci.yml, CHANGELOG.md, docs/doctoring/coverage-native-fuzz-lock-boundary.md, docs/superpowers/plans/2026-08-05-coverage-native-fuzz-lock-boundary.md (focused hunks), and tests/test_coverage_native_fuzz_lock_boundary.py plus scripts/ci/materialize_base_python_requirements.py (trusted receipts and CodeGraph blast radius; direct head-tree reads were denied in this environment, a review source limitation). Labels: Approval sufficiency: affirmative - Coverage Decision Result PASS, no unresolved non-outdated threads, no undiagnosed failed checks, no contradiction between PR intent and changed files. Verification posture: trusted Coverage execution evidence (Result: PASS, supported repository test suites passed) plus workflow gate wiring; no OPENCODE_EXECUTION_RECEIPT tool receipt exists in evidence, so no runtime-tool claim is made. Linter/static: bandit/pip_audit/trivy/npm audit configured in execution contracts; no linter/static failure evidence on this head beyond the diagnosed Strix cancellations. TDD/regression: new real temporary-Git fixture test added and executed by the diagnostics CI; doctoring record, changelog, plan, and design docs updated. Coverage: Coverage execution evidence shows supported repository test suites passed (workflow enforces --cov-branch --cov-fail-under=100 over scripts.ci.materialize_base_python_requirements). Docstring coverage: Coverage execution evidence reports configured repository docstring gates passed or advisory. DAG: flowchart (head flow, base-to-head changed flow) A["tests/test_coverage_native_fuzz_lock_boundary.py"] --> B["materialize_base_python_requirements.py exact-name classifier"] --> C["generic coverage image manifest"] --> D["OpenCode coverage evidence gate"]; E["fuzz/requirements-atheris.txt (excluded)"] -.-> C; F["requirements-property.txt and requirements-fuzz-regression.txt (included)"] --> C; G["opencode-coverage-diagnostics-ci.yml paths/pytest/compileall wiring"] --> A. PoC/execution: no execution receipt in bounded evidence; the trusted Coverage Decision and workflow gate wiring are the execution proxy; no fabricated runtime claim. DDD/domain: CI control-plane policy change confined to scripts/ci and tests; no application domain model touched. CDD/context: boundary described identically in plan, design, doctoring record, changelog, and workflow. Similar issues: prior heads of this PR iterated coverage-evidence and documentation findings; current-head Coverage Decision is PASS and the only historical bot threads are stale/superseded-head reviews. Claim/concept check: exact-name, path-independent classification claim is consistent between the doctoring record (docs/doctoring/coverage-native-fuzz-lock-boundary.md:56) and changelog; no contradicting source available in evidence. Standards search: Keep a Changelog and SemVer formats referenced; APA 7 references present in the doctoring record. Compatibility/convention: no DB/API/schema objects introduced; workflow and test naming follows repo snake_case and existing diagnostics-CI conventions. Breaking-change/backcompat: behavior change is coverage-image-only; dedicated Fuzz workflows continue to install requirements-atheris.txt directly and --require-hashes enforcement is unchanged. Implementation completeness: classifier, regression fixture, workflow wiring, changelog, and doctoring are all present; unchecked plan-doc checkboxes are implementation-plan artifacts, not code gaps. Performance: exclusion shrinks generic image install surface; no hot-path impact. Developer experience: diagnostics CI self-gates the new fixture and path filters keep CI scoped to changed surfaces. User experience: CLI/workflow-revision surface; no end-user UI. Visual/DOM: non-web change; reviewed the workflow/test/docs interaction surface instead. Accessibility/i18n: non-web; no UI strings or motion behavior. Supply-chain/license: no new dependencies added; Atheris remains hash-pinned inside dedicated fuzz workflows. Packaging: pyproject.toml requires-python >=3.10 contract present; unpackaged_source_surfaces empty. Security/privacy: the exact-name exclusion is a strict reduction of trusted inputs (no unhashed fallback, no replacement download), no secrets/auth/tenant surfaces touched, and identifier enumeration is not applicable; Strix runs on this head were CANCELLED due to a higher-priority waiting request for strix-pull_request_target-ContextualWisdomLab/.github-pr-777 (annotations at .github:1 and .github:111), a diagnosed scheduling cancellation with no Strix model vulnerability reports in evidence.

Approval sufficiency: bounded evidence supplied affirmative approval evidence for changed files, coverage/docstring posture, risk surfaces, and current-head verification; approval is not based merely on the absence of known blockers.
Verification posture: CodeGraph evidence was initialized and bounded current-head evidence reviewed for changed-file evidence including .github/workflows/opencode-coverage-diagnostics-ci.yml, CHANGELOG.md, docs/doctoring/coverage-native-fuzz-lock-boundary.md, docs/superpowers/plans/2026-08-05-coverage-native-fuzz-lock-boundary.md, docs/superpowers/specs/2026-08-05-coverage-native-fuzz-lock-boundary-design.md, and 2 more.
Linter/static: workflow/static review evidence is bounded by the current-head GitHub Checks gate and changed-file evidence.
TDD/regression: coverage execution evidence and focused changed hunks were reviewed from bounded-review-evidence.md.
Coverage: coverage execution evidence reports supported repository test suites passed.
Docstring coverage: coverage execution evidence reports configured repository docstring gates passed or docstring coverage was advisory.
DAG: CodeGraph/source-backed behavior map connects .github/workflows/opencode-coverage-diagnostics-ci.yml to the affected review, runtime, or workflow path and required checks.
PoC/execution: coverage-evidence job executed on the current head and reported PASS.
DDD/domain: workflow and repository-governance invariants were reviewed against changed files in bounded evidence.
CDD/context: CodeGraph evidence, changed-file history, and focused hunks were reviewed from bounded-review-evidence.md.
Similar issues: changed-file history evidence was reviewed for comparable local precedents.
Claim/concept check: bounded evidence, repository source, current-head workflow evidence, and, where numeric, scientific, statistical, or literature-backed claims are affected, original-paper/formula evidence and parameter-recovery expectations were used for claims.
Standards search: standards and external-source claims require trusted bounded source evidence prepared outside the isolated model process; no evidence-backed standards blocker is present in bounded evidence.
Compatibility/convention: changed workflow/script conventions, object naming, and reserved-word safety for schema/API/config/code surfaces were checked in bounded evidence.
Breaking-change/backcompat: deployment evidence and changed-file history were checked for backward-compatibility risk.
Performance: changed surfaces were checked for performance risk in bounded evidence.
Developer experience: changed automation, review, test, setup, and maintenance surfaces were checked for helpful or obstructive DX impact in bounded evidence.
User experience: connected user, operator, API, CLI, documentation, review-comment, status-check, rendering, and workflow-reader behavior was checked for contradictions against code, docs, and tests in bounded evidence.
Visual/DOM: deterministic repair does not infer browser runtime execution; source-backed DOM/UI evidence and trusted workflow receipts were reviewed when present, and non-web surfaces used API/CLI/log/docs/workflow evidence instead.
Accessibility/i18n: accessibility, localization, and human-readable text surfaces were checked where UI, CLI, API message, docs, logs, or review text changed.
Supply-chain/license: dependency, package, model, container, and external-tool changes were checked in bounded evidence.
Packaging: package, build, test, lint, and security contracts were checked in bounded evidence.
Security/privacy: workflow-token, review-gate, and repository-automation security/privacy boundaries were checked in bounded evidence.

Review the current exact head only. Verify exact-name native fuzz-lock exclusion, preservation of every nonexact/property/regression lock, immutable trusted-base Git reads, hash/symlink/path enforcement, realistic false-positive and bypass tests, 100% statement/branch/docstring evidence, APA 7 doctoring, and protected-branch semantics. Treat all predecessor-head coverage requests as stale. Approve only when current-head checks and independent evidence are complete.

@seonghobae I reviewed only exact head 66d5a26498503361aa814e5be742ac8c6335246b.

I found no current source-level blocker.

Verified items:

  • The classifier excludes only the exact basename requirements-atheris.txt.
  • The classifier uses PurePosixPath(path).name. Module depth does not change classification.
  • requirements-atheris-regression.txt and requirements-property.txt remain eligible.
  • The temporary Git fixture proves nested Atheris exclusion and nested property/regression lock retention.
  • The materializer accepts only a 40-character base SHA.
  • The materializer reads the tree and blobs from that exact base SHA.
  • Hash-pinned selection remains required.
  • Existing controls reject malformed Git-tree entries and symlink output directories.
  • Existing controls skip unsafe paths and non-blob entries.
  • Sorting preserves deterministic materialization order.
  • The exact diff does not modify a dedicated Fuzz workflow.
  • CHANGELOG.md and the doctoring record define the boundary, rollback condition, and APA 7 references.
  • Exact-head run 30991153826 completed successfully. Its Python 3.10 and Python 3.14 jobs succeeded.
  • The permanent diagnostics gate includes the regression fixture. It enforces --cov-branch, --cov-fail-under=100, and interrogate --fail-under 100.

I could not read the protected-branch configuration. The branch-protection API returned HTTP 403 for this review token. GitHub reports that PR #763 is already merged and has an approved review decision. Therefore, no further approval action applies.

Pull request overview

OpenCode reviewed the current-head bounded evidence and requested changes before merge.

Findings

1. P1 scripts/ci/materialize_base_python_requirements.py:24 - Core changed surface (exact-name native fuzz-engine lock classifier and its fixture) is not inspectable in the trusted evidence - fail-closed until hunks are supplied

  • Problem: The PR's central behavior is a new exact-name classifier that excludes requirements-atheris.txt from trusted-base generic coverage materialization at any module depth while keeping hash-pinned property/regression locks eligible. The trusted current-head evidence for this run contains no diff hunks for scripts/ci/materialize_base_python_requirements.py or tests/test_coverage_native_fuzz_lock_boundary.py: the Focused changed hunks section of bounded-review-evidence.md truncates at the plan document with the marker '[Prompt evidence truncated after 12000 of 23673 bytes ...]' (bounded-review-evidence.md:991-993), and the precomputed CodeGraph changed-scope exploration for this PR's changed files surfaced only unrelated sources (scripts/ci/r_coverage_peer_gate.py, tests/test_noema_review_gate.py, tests/test_opencode_existing_approval_gate.py) and reports 'no covering tests found' for materialize at scripts/ci/materialize_base_python_requirements.py:214. Direct reads of /home/runner/work/_temp/opencode-pr-head are denied by this runtime's permission policy. Because materialize is the org-wide coverage dependency materializer (blast radius: every repository's coverage evidence), approval requires affirmative source evidence of the classifier's exact-name (non-substring) matching, path-independent placement in the blob-selection flow, and fail-closed behavior on malformed Git trees, symlinks, and unpinned lines; that evidence is absent in this run. The workflow wiring (paths filters, pytest step with --cov-branch --cov-fail-under=100, compileall) and the Coverage execution evidence Result: PASS are present and consistent, but they do not substitute for the classifier source itself, which the review contract requires before approving material script changes.
  • Root cause: Evidence-generation truncation cut the Focused changed hunks before the materializer/test diffs, and this run's CodeGraph changed-scope exploration did not cover the changed files' source or test reachability (it returned unrelated files and 'no covering tests found' for materialize at :214).
  • Fix: Supply the full current-head diff hunks for scripts/ci/materialize_base_python_requirements.py and tests/test_coverage_native_fuzz_lock_boundary.py in the trusted evidence (or make the head checkout readable to reviewers) and re-run the CodeGraph changed-scope exploration for these files so the classifier predicate, its call site inside materialize, and the fixture assertions (generated manifest contains only requirements-property.txt and requirements-fuzz-regression.txt; exact-name exclusion does not match substrings or directory names) are source-backed. Also surface the new identifier names so the two-word naming and reserved-word conventions can be checked.
  • Regression test: python3 -m pytest tests/test_coverage_native_fuzz_lock_boundary.py tests/test_materialize_base_python_requirements.py -q; plus the diagnostics workflow gate python -m pytest tests/test_coverage_native_fuzz_lock_boundary.py --cov=scripts.ci.materialize_base_python_requirements --cov-branch --cov-fail-under=100 -q
  • Suggested diff: posted in this finding's inline review thread.

Summary

PR #763 (fix(coverage): keep native fuzz locks out of generic images). Changed-file evidence inspected: .github/workflows/opencode-coverage-diagnostics-ci.yml (pull_request/push paths filters, 'Run diagnostics and lock contracts with full branch coverage' pytest step, 'Compile changed Python surfaces' step), CHANGELOG.md, docs/doctoring/coverage-native-fuzz-lock-boundary.md, docs/superpowers/plans/2026-08-05-coverage-native-fuzz-lock-boundary.md, docs/superpowers/specs/2026-08-05-coverage-native-fuzz-lock-boundary-design.md. Blocking: the two core changed files scripts/ci/materialize_base_python_requirements.py and tests/test_coverage_native_fuzz_lock_boundary.py have no hunks in the trusted evidence (Focused changed hunks truncates at the plan doc, bounded-review-evidence.md:991-993), the CodeGraph changed-scope exploration for these changed files surfaced only unrelated sources (r_coverage_peer_gate.py, test_noema_review_gate.py, test_opencode_existing_approval_gate.py) and reports 'no covering tests found' for materialize at scripts/ci/materialize_base_python_requirements.py:214, and direct reads of /home/runner/work/_temp/opencode-pr-head are denied in this runtime - the exact-name Atheris-lock classifier semantics therefore cannot be affirmatively verified, so this review fails closed (REQUEST_CHANGES). DAG: flowchart LR with quoted labels mapping opencode-coverage-diagnostics-ci.yml -> materialize_base_python_requirements.py materialize:214 -> exact-name native fuzz-engine lock classifier (hunks absent from evidence) -> generic coverage image lock set; fixture test -> classifier; dedicated Fuzz workflow (unchanged) as the parallel execution path; head-flow from workflow hunks, classifier internals unverified. Approval sufficiency: NOT met - core changed surface uninspectable; positive evidence for changed-file behavior required by contract. Verification posture: Coverage execution evidence Result: PASS (supported repository test suites passed); docstring gates passed or advisory; no OPENCODE_EXECUTION_RECEIPT lines exist in the evidence, so no per-run tool receipt is citable (execution limitation). Linter/static: repo lint_commands cover hadolint/npm audit/pip_audit/bandit/trivy; diagnostics workflow runs compileall on changed surfaces including the new test. TDD/regression: fixture is described (real temp-Git base with fuzz/requirements-atheris.txt, fuzz/requirements-property.txt, services/example_service/requirements-fuzz-regression.txt; manifest must contain only property/regression locks; second contract for exact-name non-substring classification) but fixture source is not in the evidence. Coverage: trusted Coverage execution evidence Result: PASS - supported repository test suites passed (diagnostics workflow enforces --cov-branch --cov-fail-under=100 on scripts.ci.materialize_base_python_requirements). Docstring coverage: configured repository docstring gates passed or advisory per Coverage execution evidence. DAG: see mermaid in this summary (head flow; classifier internals unverified). PoC/execution: none - no execution receipts present. DDD/domain: lock-role classification (native fuzz engine vs property/regression) is a clear domain rule, documented in the doctoring record and changelog. CDD/context: change sits at the org-wide coverage materialization trust boundary; docs/changelog/plan/spec are mutually consistent with PR intent. Similar issues: repo history shows the materializer evolved through evidence-backed changes (#657 content-based discovery, #661, #668); this PR follows that pattern. Claim/concept check: docs claim exact-name, path-independent exclusion with substring/directory-name regression contract and unchanged hash-pinning/immutable-base trust - unverifiable from evidence (docs are PR-controlled text). Standards search: Keep a Changelog 1.1.0 and SemVer 2.0.0 links in CHANGELOG.md; APA 7 references in the doctoring record; no contradiction found in evidenced content. Compatibility/convention: workflow naming/paths follow sibling entries; classifier identifiers inside the uninspectable file cannot be naming/reserved-word reviewed. Breaking-change/backcompat: exclusion changes which locks enter generic coverage images; dedicated Fuzz workflows unchanged per docs; no public API surface changed. Implementation completeness: unverifiable for the classifier; all doc artifacts (changelog, doctoring, plan, spec) present. Performance: exclusion reduces image installs; no measurable regression evidenced or expected. Developer experience: DX surface = coverage-diagnostics workflow; new fixture is wired into triggers, pytest (with branch-coverage gate), and compileall, matching sibling test wiring. User experience: UX surface = repository coverage evidence flow; policy-only change, no interactive UI; docs state application/test import failures remain fail-closed (not suppressed). Visual/DOM: non-web change; interaction surface reviewed = workflow config, review-comment output, and docs. Accessibility/i18n: not applicable (non-web); docs English-only, consistent with repository. Supply-chain/license: exclusion reduces installed native artifacts; hash-pinning and exact-base reads preserved per doctoring record - no evidence of weakening. Packaging: pyproject.toml (requires-python >=3.10) defines test/coverage/docstring commands; scripts/ci package covered by pytest per coverage evidence. Security/privacy: no secrets/authz surface changed; trust-boundary invariants (immutable base, malformed-tree/symlink fail-closed) documented as unchanged but classifier internals unverified. Blocking finding: P1 scripts/ci/materialize_base_python_requirements.py:24 - evidence gap for the core classifier; supply the materializer and fixture diff hunks (or a readable head checkout) for re-review.

  • Result: REQUEST_CHANGES

  • Reason: Core changed files (scripts/ci/materialize_base_python_requirements.py exact-name Atheris-lock classifier and tests/test_coverage_native_fuzz_lock_boundary.py fixture) are uninspectable in the trusted evidence: their focused hunks are truncated out, the CodeGraph changed-scope exploration returned only unrelated sources with 'no covering tests found' for materialize at :214, and the head checkout is unreadable in this runtime; fail-closed per contract until the materializer/test diffs are supplied.

P1 Core changed surface (exact-name native fuzz-engine lock classifier and its fixture) is not inspectable in the trusted evidence - fail-closed until hunks are supplied

  • Location: scripts/ci/materialize_base_python_requirements.py:24
  • Problem: The PR's central behavior is a new exact-name classifier that excludes requirements-atheris.txt from trusted-base generic coverage materialization at any module depth while keeping hash-pinned property/regression locks eligible. The trusted current-head evidence for this run contains no diff hunks for scripts/ci/materialize_base_python_requirements.py or tests/test_coverage_native_fuzz_lock_boundary.py: the Focused changed hunks section of bounded-review-evidence.md truncates at the plan document with the marker '[Prompt evidence truncated after 12000 of 23673 bytes ...]' (bounded-review-evidence.md:991-993), and the precomputed CodeGraph changed-scope exploration for this PR's changed files surfaced only unrelated sources (scripts/ci/r_coverage_peer_gate.py, tests/test_noema_review_gate.py, tests/test_opencode_existing_approval_gate.py) and reports 'no covering tests found' for materialize at scripts/ci/materialize_base_python_requirements.py:214. Direct reads of /home/runner/work/_temp/opencode-pr-head are denied by this runtime's permission policy. Because materialize is the org-wide coverage dependency materializer (blast radius: every repository's coverage evidence), approval requires affirmative source evidence of the classifier's exact-name (non-substring) matching, path-independent placement in the blob-selection flow, and fail-closed behavior on malformed Git trees, symlinks, and unpinned lines; that evidence is absent in this run. The workflow wiring (paths filters, pytest step with --cov-branch --cov-fail-under=100, compileall) and the Coverage execution evidence Result: PASS are present and consistent, but they do not substitute for the classifier source itself, which the review contract requires before approving material script changes.
  • Root cause: Evidence-generation truncation cut the Focused changed hunks before the materializer/test diffs, and this run's CodeGraph changed-scope exploration did not cover the changed files' source or test reachability (it returned unrelated files and 'no covering tests found' for materialize at :214).
  • Fix: Supply the full current-head diff hunks for scripts/ci/materialize_base_python_requirements.py and tests/test_coverage_native_fuzz_lock_boundary.py in the trusted evidence (or make the head checkout readable to reviewers) and re-run the CodeGraph changed-scope exploration for these files so the classifier predicate, its call site inside materialize, and the fixture assertions (generated manifest contains only requirements-property.txt and requirements-fuzz-regression.txt; exact-name exclusion does not match substrings or directory names) are source-backed. Also surface the new identifier names so the two-word naming and reserved-word conventions can be checked.
  • Regression test: python3 -m pytest tests/test_coverage_native_fuzz_lock_boundary.py tests/test_materialize_base_python_requirements.py -q; plus the diagnostics workflow gate python -m pytest tests/test_coverage_native_fuzz_lock_boundary.py --cov=scripts.ci.materialize_base_python_requirements --cov-branch --cov-fail-under=100 -q

Suggested diff

No suggestion-ready diff is possible without the actual file content; the requested change is evidence availability, not a code-line change. Directional addition-only sketch that would make the exact-name contract independently reviewable if the current implementation lacks it:
+NATIVE_FUZZ_ENGINE_LOCK_NAMES: frozenset[str] = frozenset({"requirements-atheris.txt"})
+
+def is_native_fuzz_engine_lock(lock_path: str) -> bool:
+    """Return whether an exact-name candidate is a native fuzz-engine lock."""
+    return Path(lock_path).name in NATIVE_FUZZ_ENGINE_LOCK_NAMES

@seonghobae I reviewed exact head 66d5a26498503361aa814e5be742ac8c6335246b.

I found no current actionable source-level finding.

Verified items:

  • The classifier excludes only the exact basename requirements-atheris.txt.
  • Classification is independent of module depth because it uses PurePosixPath(path).name.
  • The temporary Git fixture excludes the nested Atheris lock.
  • The fixture retains nested requirements-property.txt and requirements-fuzz-regression.txt.
  • The materializer validates a 40-character base SHA.
  • The materializer reads the Git tree and blobs from that exact base SHA.
  • Hash-pinned lock selection remains enforced.
  • Existing tests retain malformed-tree rejection, non-blob rejection, deterministic ordering, and output-directory symlink rejection.
  • No dedicated fuzz workflow changed in the exact diff.
  • No NVIDIA NIM or reviewer credential file changed between the reviewed base and head.
  • Exact run 30991153826 succeeded on this head.
  • The run used --cov-branch and --cov-fail-under=100.
  • The run reported 100% statement and branch coverage for scripts/ci/materialize_base_python_requirements.py.
  • The run reported 100.0% production docstring coverage with interrogate --fail-under 100.

I could not read protected-branch settings because the GitHub branch-protection API returned HTTP 403 for the review token.
