Why this change

PR #827 extracted the LLVM 19 check into scripts/ci/ensure_rust_llvm19.sh and left .github/workflows/opencode-review-dispatch.yml identical to main. That helper is current-head source. The coverage sandbox measures untrusted PR trees, so a helper-only pin cannot bind the coverage producer.

The previously approved head 2acaa179 already had the trusted 19-line binding: llvm-19 in the coverage image, ENV + RUN test -x, docker run --env, and the ensure_rust_toolchain fail-closed guard. This PR restores that trusted path and pairs REVIEW_DISPATCH_BLOB_SHA with the updated workflow blob.

What operators should do next

Review the restored producer pin, then merge this branch instead of #827. After merge, rebuild the trusted coverage image from default-branch opencode-review-dispatch.yml before treating Rust coverage as current-head evidence.

Do not merge #827 while its head still omits the trusted 19 lines.

Verification

Focused contract tests passed locally: tests/test_opencode_rust_coverage_toolchain_contract.py, tests/test_pr_review_autofix_nvidia_nim_contract.py, and related dispatch/coverage tests (46 passed, 1 skipped when the host lacks /usr/bin/llvm-cov-19).

Trust boundary

The runtime check stays in trusted default-branch workflow source. The helper is a readable extract and override-resistant contract, not the enforcement point. Updating opencode-review-dispatch.yml updates the independent review-dispatch blob SHA pin; it does not move review-agent credentials or approval authority.

Refs #827 and #816.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 3a3c2

The PR restores the trusted LLVM 19 coverage binding and updates its workflow pin, but the current changes still contain a generated runtime NameError, a repair workflow that can fail on reruns, an unhandled invalid-lock encoding failure, and a lint error; merge should wait until these bounded correctness and CI issues are fixed.

Review

Head a2d4924f restores the trusted LLVM 19 producer pin and now fail-closes when that pin drifts from the independent review-dispatch identity.

What is sound

  • Coverage image, docker run --env, and ensure_rust_toolchain all bind /usr/bin/llvm-cov-19 and /usr/bin/llvm-profdata-19. The helper is a readable extract, not the enforcement point.
  • REVIEW_DISPATCH_BLOB_SHA=de1c4800d362bda4a90c31a0c8e39687a782afb4 matches git hash-object of .github/workflows/opencode-review-dispatch.yml.
  • The follow-up commit watches tests/test_pr_review_autofix_nvidia_nim_contract.py from the LLVM quality CI and asserts the blob pin there. The hourly NVIDIA NIM quality workflow still does not watch opencode-review-dispatch.yml, so that pairing check has to live in the workflow that actually retriggers on a producer rewrite.
  • Local contract: 8 passed, 1 skipped (this host has no /usr/bin/llvm-cov-19). Quality CI already passed on 7b7686d6.

Do not merge #827 while its head still omits the trusted 19 lines. This is the landing vehicle.

Next operator action

  1. Merge this PR after required checks on a2d4924f complete.
  2. Rebuild the trusted coverage image from default-branch opencode-review-dispatch.yml before treating DiskSage or fast-mlsirm Rust coverage as current-head evidence.
  3. Close or retire #827 after this merge. Do not open a third LLVM-pin PR.

Review

Head a2d4924f is the LLVM 19 landing vehicle. Local contract evidence: 31 passed, 1 skipped on tests/test_opencode_rust_coverage_toolchain_contract.py and tests/test_pr_review_autofix_nvidia_nim_contract.py (skip is host missing /usr/bin/llvm-cov-19). git hash-object of .github/workflows/opencode-review-dispatch.yml equals REVIEW_DISPATCH_BLOB_SHA=de1c4800d362bda4a90c31a0c8e39687a782afb4.

What is sound

  • Trusted coverage image installs llvm-19, binds ENV LLVM_COV=/usr/bin/llvm-cov-19 and ENV LLVM_PROFDATA=/usr/bin/llvm-profdata-19, and RUN test -x both paths.
  • Isolated docker run --env passes the same literals; ensure_rust_toolchain fail-closes before cargo llvm-cov; failures != 0 exits the sandbox.
  • scripts/ci/ensure_rust_llvm19.sh is a readable extract only. It is not the enforcement point.
  • Quality CI watches opencode-review-dispatch.yml and the NVIDIA NIM contract so a producer rewrite cannot leave the independent review-dispatch blob stale. Hourly NIM quality still does not watch opencode-review-dispatch.yml; that split is the documented control separation.
  • Review-agent credentials, model keys, and approval authority are unchanged.

Do not merge #827. That head (55a7292a) still omits the trusted 19-line producer pin in opencode-review-dispatch.yml.

Next operator action

Merge this PR after the required OpenCode, Strix, and Noema reviews complete. The next default-branch repository_dispatch rebuilds the coverage image with --no-cache; treat that successful run as the first current-head LLVM 19 evidence. Then close or leave closed #827 so a helper-only pin cannot land.

Current-head repair: rebased the LLVM 19 coverage producer-pin branch onto main bbedc1a and fixed the materializer regression exposed during verification. Exact head 8e05e25. Bounded relative -r/--requirement includes now remain accepted only when resolved from the exact base to direct regular SHA-256-pinned leaves; generated paths are rewritten and missing/unsafe/nested/non-pinned edges fail closed. Focused materializer/uv/LLVM contract suite: 94 passed, 1 skipped; actionlint and git diff --check were run on the changed workflows. Protected hosted checks remain; no bypass used.

seonghobae and others added 17 commits August 20, 2026 10:32
Bind Rust coverage to reviewed llvm-cov-19 executables so a runner
PATH change cannot silently replace the producer. Darwin trusted-uv
tests exercise the linux x86_64 installer path.
Restore opencode-review-dispatch.yml to the reviewed review-agent blob
and bind LLVM 19 coverage tools in scripts/ci/ensure_rust_llvm19.sh.
Keep the runtime check in the default-branch coverage image and
ensure_rust_toolchain guard so a pull-request-head helper cannot
change the coverage producer. Pair the review-dispatch blob SHA
with that workflow and fail closed when the reviewed paths drift.

The LLVM 19 quality CI already watches opencode-review-dispatch.yml, but
the hourly NVIDIA NIM gate that owns REVIEW_DISPATCH_BLOB_SHA does not.
Pair the blob pin in the workflow that retriggers on a producer rewrite

review-dispatch identity stale.

These are compatibility and trust-boundary constants, not caller-selectable
configuration. The reviewed helper `scripts/ci/ensure_rust_llvm19.sh` binds both
exact paths and fails closed unless the live `LLVM_COV` / `LLVM_PROFDATA`
values match and are executable before Rust coverage evidence is admitted. The
independent OpenCode review-dispatch workflow stays byte-for-byte so the
review-agent key system is not rewritten to carry this runtime check.

도구 바인딩과 blob pin의 담당자를 정확히 문서화하십시오.

scripts/ci/ensure_rust_llvm19.shLLVM_COVLLVM_PROFDATA를 설정하지 않습니다. 이 스크립트는 이미 설정된 값이 고정 경로와 일치하는지 검증합니다. 바인딩은 .github/workflows/opencode-review-dispatch.ymlENVdocker run --env에서 수행합니다.

또한 이 PR은 opencode-review-dispatch.yml을 변경하고 REVIEW_DISPATCH_BLOB_SHA도 갱신합니다. “stays byte-for-byte”는 현재 계약과 맞지 않습니다. 의도된 워크플로 변경에는 대응하는 blob SHA 갱신이 필요하다고 설명하십시오.

NIST SP 800-218 PW.4.1 requires third-party software to come from expected,
trusted sources with integrity verification (Souppaya et al., 2022). The exact
`/usr/bin/llvm-cov-19` and `/usr/bin/llvm-profdata-19` bindings are
producer-selection controls: they select reviewed paths and `test -x` verifies
executability. They do not hash or signature-verify the Debian package or binary.
Package/image hashes, signatures, repository metadata, and attestations are
separate integrity controls and must not be inferred from path equality.

NIST control 인용을 수정하십시오.

현재 문구는 PW.4.1이 무결성 검증을 요구한다고 설명합니다. PW.4.1은 안전한 제3자 구성 요소의 획득·유지와 provenance 검토를 다룹니다. 디지털 서명 또는 다른 방식으로 구성 요소 무결성을 확인하는 내용은 PW.4.4에 있습니다. 감사 근거가 잘못 연결되지 않도록 문구를 분리하거나 PW.4.4를 함께 인용하십시오. (nvlpubs.nist.gov)

29, Revise the NIST citation in the paragraph beginning “NIST SP 800-218 PW.4.1”
so PW.4.1 is limited to trusted acquisition, maintenance, and provenance review;
attribute digital signatures or other component-integrity verification to
PW.4.4, or clearly separate that control from PW.4.1.

비-UTF-8 lock에서 발생하는 예외를 fail-closed 오류로 변환하십시오.

_requirement_lineserrors="ignore"로 디코딩합니다. 따라서 잘못된 UTF-8 바이트를 포함한 base lock도 _is_hash_pinned 검증을 통과할 수 있습니다. 이 경우 Line 628의 errors="strict" 디코딩이 UnicodeDecodeError를 발생시키고, materialize는 처리되지 않은 traceback으로 중단됩니다. 다른 실패 경로와 동일하게 명시적인 RuntimeError로 실패하도록 하십시오.

생성 코드의 Path 참조를 pathlib.Path로 수정하십시오.

Line 177은 Path(*relative_target.parts)scripts/ci/materialize_base_python_requirements.py에 삽입합니다. 해당 모듈은 pathlib을 import하며, 이름 Path를 bind하지 않습니다. 따라서 생성된 materialize는 include가 존재할 때 NameError를 발생시킵니다.

현재 이 결함은 .github/workflows/repair-pr827-coderabbit-comments.yml Line 59-63의 인라인 패치로 가려져 있습니다. 근본 원인을 여기서 수정하면 해당 워크플로 패치 단계를 삭제할 수 있습니다.
