Summary

  • Bind OpenCode coverage-source evidence to one immutable artifact ID and the producer-attested GitHub workflow attempt.
  • Validate positive current-attempt identity before downloading by artifact ID.
  • Fail closed with full-rerun or fresh-dispatch guidance when producer, identity, or download evidence is unavailable.
  • Preserve one-day source retention and the credential-free actions: read consumer boundary.

Lineage and exact identities

This clean current-main successor supersedes #812, whose donor head diverged from protected main and contained a historically truncated central workflow. The successor was rebuilt from independently resolved protected main 6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba; no checks, reviews, approvals, or generated merge evidence from the donor transfer.

  • Exact current head: 5cf988c7aca0541fa7a6561c55667a52caf306ec.
  • Exact protected-base snapshot and live base: 6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba.
  • GitHub reports the ready head mechanically mergeable.

During connector publication, a size-capped local read initially truncated the central workflow in commit 308d2b8a79e1e5ba5531d4a776135fe616c76974. That defect was detected before external consumption and repaired from GitHub's complete protected-main blob in 44e3ecc66312e2c232b8f415322d09d84983aa1a.

After the previously bounded head 498867cf05079120aa89c05fe1d13b65b26084a4, unrelated architecture and trusted-lock-test drift entered this branch. A non-destructive forward commit now points to the exact previously bounded tree. GitHub compare reports zero changed files between 498867cf... and the current head. No force-push, rebase, history rewrite, or predecessor evidence transfer was used.

The final comparison is bounded to exactly six permanent files:

  • .github/workflows/opencode-coverage-artifact-rerun-quality-ci.yml;
  • .github/workflows/opencode-review-dispatch.yml;
  • CHANGELOG.md;
  • docs/doctoring/opencode-coverage-artifact-reruns.md;
  • scripts/ci/test_strix_quick_gate.sh; and
  • tests/test_opencode_coverage_artifact_rerun_contract.py.

Every predecessor check, review, and approval is historical only; current-head evidence must regenerate.

Test-first and product contract

  • RED: the focused contract fails against unmodified protected main because immutable artifact-ID and producer-attempt binding are absent.
  • The consumer never searches for, selects, or falls back to an artifact from a prior run or attempt.
  • It receives no repository-content, model, OIDC, or write credential.
  • Missing or expired current-attempt evidence remains a hard failure and directs operators to run the complete workflow or issue a fresh repository dispatch.
  • The central workflow retains its target job, terminal scheduler sentinel, exact-head/source validation, archive-member validation, isolated execution, coverage, docstring, security, and approval boundaries.
  • No temporary, one-shot, self-modifying, encoded-patch, branch-writer, approval-bypass, or stale-artifact path remains in the bounded tree.

Verification posture

The previously bounded tree completed its focused contract, full repository suite, 100% owned production statement/branch coverage, public documentation gate, compilation, Strix, security, SAST, dependency, and supply-chain checks with zero unresolved thread. Those results prove the prior head only.

The current head must regenerate every applicable exact-head quality, security, supply-chain, and semantic-review result. Pending, queued, skipped, cancelled, absent, stale, predecessor-head, local-only, author-only, status-only, synthetic, or model-only evidence is not acceptance.

Acceptance

Merge or auto-merge only after the unchanged current head has terminal-success required gates, zero valid unresolved findings, a qualifying current-head semantic verdict, the independent non-author formal approval required by live rules, a compatible live base, and ordinary expected-head merge authority. Closing #811 additionally requires protected-main operational rerun evidence; source-branch success alone is insufficient. No administrative bypass, self-approval, synthetic approval, or protection weakening is requested.

Supersedes #812.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to d0e59

The change tightens coverage-artifact identity and fail-closed workflow behavior, but the current branch does not fully enforce those guarantees in its contract tests, including artifact-path binding, pre-execution guard ordering, conflict-repair protections, and reordered-inventory rejection. This can allow workflow security or correctness regressions to pass validation, so merge is not ready without fixes or explicit owner acceptance.

Evaluate exact current head 498867cf05079120aa89c05fe1d13b65b26084a4 against independently resolved live main 6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba. All ten observed exact-head workflows are terminal-success, GitHub reports the ready head mergeable, and unresolved threads are zero. Review immutable artifact-ID selection, producer workflow-attempt attestation, and rerun-safe coverage-source binding only on this head. Submit only a current-head semantic verdict; keep automated judgment separate from qualifying independent human approval, merge authority, and protected-main operational acceptance.

Review exact current head 498867cf05079120aa89c05fe1d13b65b26084a4 only. All exact-head quality, security, supply-chain, Strix, and artifact-rerun workflows are terminal-success; the remaining CodeRabbit note is explicitly optional. Validate immutable upload artifact ID plus producer-attempt binding, positive current-attempt identity checks, exact-ID download only, one-day retention, credential-free consumer permissions, fail-closed full-rerun/fresh-dispatch recovery, and absence of prior-artifact search or temporary writers. Review only; do not mutate, merge, or alter protections.

Exact-current-head review request for 498867cf05079120aa89c05fe1d13b65b26084a4 over protected main@6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba.

Review the bounded six-file attempt-scoped artifact repair: immutable artifact ID, positive producer workflow-attempt identity before download, no search or stale-attempt fallback, exact-head/source/archive validation, one-day retention, credential-free actions: read consumer, and fail-closed rerun guidance when evidence is missing. OpenCode Coverage Artifact Rerun Quality CI, Strix Changed Path Quality CI, CodeQL PR, Python Security, Security Scan, SAST Semgrep, Secret Scan, OSV-Scanner PR, Scorecard PR, and SBOM Generation are terminal-success on this exact head. CodeRabbit reported only an optional low-value audit→block hardening suggestion; no unresolved thread exists.

Keep this exact head unchanged. Do not update the branch, synthesize author approval, search for an older artifact, widen credentials, merge, release, or bypass protection.

Review exact current head 498867cf05079120aa89c05fe1d13b65b26084a4 only. Validate immutable coverage-source artifact identity across github.run_attempt, producer-attested artifact ID and attempt, positive current-attempt validation before exact-ID download, one-day retention, actions: read credential-free consumer scope, non-terminating diagnostic plus aggregate fail-closed recovery reporting, and the prohibition on searching prior artifacts. The CodeRabbit egress-policy suggestion is explicitly optional and outside this bounded identity repair; do not treat it as a source defect unless the current workflow permits an ungoverned endpoint. Exact-head quality, Strix, security, SAST and supply-chain runs are terminal-success; there are no inline threads. Review only; do not mutate, merge, release, or bypass protection.

Exact-current-head automated and independent review requested for 498867cf05079120aa89c05fe1d13b65b26084a4 against protected main@6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba.

Fresh evidence: the focused artifact-rerun quality workflow plus all nine generic exact-head workflows are terminal-success, no inline thread exists, and the only CodeRabbit note is an explicitly optional egress-hardening suggestion rather than a current blocker. Review the immutable artifact-ID and positive producer-attempt binding, credential-free actions: read consumer boundary, exact-head archive/member validation, and fail-closed rerun/fresh-dispatch behavior when current-attempt evidence is unavailable. The consumer must never search for or fall back to a prior run or attempt.

Submit an exact-head verdict without updating the branch, extending retention to hide identity loss, enabling stale-artifact fallback, synthesizing author approval, or bypassing protection.

Pull request overview

OpenCode reviewed the current-head bounded evidence and found no blocking issues.

Findings

No blocking findings.

Summary

Approval sufficiency: APPROVE - affirmative evidence from inlined current-head changed-file hunks for .github/workflows/opencode-review-dispatch.yml and .github/workflows/opencode-coverage-artifact-rerun-quality-ci.yml, Coverage execution evidence PASS, no failed GitHub Checks, no unresolved review threads. Verification posture: Coverage execution evidence records supported repository test suites passed; no OPENCODE_EXECUTION_RECEIPT lines were present for repository_dispatch runtime behavior, so runtime claims rest on source traces and static contract tests (source limitation). Linter/static: no failed lint checks in evidence; the new quality workflow adds compileall over scripts and tests. TDD/regression: new 187-line contract test tests/test_opencode_coverage_artifact_rerun_contract.py plus tests/test_materialize_base_python_requirements.py additions, wired into the new quality CI and recorded PASS. Coverage: supported repository test suites passed per Coverage execution evidence (PASS decision). Docstring coverage: Coverage execution evidence - configured repository docstring gates passed or advisory; quality workflow runs interrogate scripts/ci. DAG: base-to-head flowchart of coverage-source-tree upload -> attempt identity gate -> artifact-ids download -> tar validation (see review body); reflects the changed head flow. PoC/execution: no trusted execution receipts in evidence; static source-trace analysis only for GitHub Actions runtime behavior. DDD/domain: CI control-plane infrastructure change; no domain model surface touched. CDD/context: control-plane workflow context; no application contexts affected. Similar issues: extends prior artifact-binding hardening (PR #687, dependency bump #596) with attempt scoping. Claim/concept check: PR claim bind coverage artifacts to workflow attempts verified against the attempt-scoped artifact name, producer-attested run_attempt output, and fail-closed identity gate in the diff. Standards search: SLSA attempt-scoped artifact identity cited in CHANGELOG/ARCHITECTURE docs; no external lookup possible in this sandbox (source limitation). Compatibility/convention: new identifiers coverage_source_artifact_id, coverage_source_run_attempt, artifact_id, exact-head-contract are multi-word and idiomatic; no reserved-word risk. Breaking-change/backcompat: artifact name changed from opencode-coverage-source to attempt-scoped and download switched from name to artifact-ids; uploader and downloader updated in the same PR and no external consumers appear in CodeGraph evidence. Implementation completeness: all new steps (attempt validation, output plumbing, identity gate, unified fail-closed report) are fully implemented; no placeholders. Performance: CI-only; concurrency cancel-in-progress prevents redundant runs. Developer experience: actionable fail-closed guidance (full rerun or fresh repository dispatch) plus new operator doctoring doc. User experience: operator/CI output surface reviewed - ::error:: messages name the exact remediation. Visual/DOM: non-web change; no DOM surface; CLI/workflow/docs interaction surface reviewed instead. Accessibility/i18n: non-web; no i18n surface. Supply-chain/license: third-party actions SHA-pinned with version comments, hash-locked pip install (--require-hashes), no new dependencies. Packaging: python contract via pyproject.toml; no unpackaged source surfaces in evidence; compileall gate added. Security/privacy: least-privilege contents:read, egress-policy audit, retained tar-member validation before extraction, fail-closed identity checks, no secrets or credential changes.

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-artifact-rerun-quality-ci.yml, .github/workflows/opencode-review-dispatch.yml, ARCHITECTURE.md, CHANGELOG.md, CLAUDE.md, and 4 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-artifact-rerun-quality-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.

Returned to Draft because the exact current tree contradicts the body’s six-file bounded-closure claim.

The valid product slice is the attempt-scoped coverage artifact contract: immutable artifact ID, producer workflow-attempt identity, positive pre-download validation, credential-free actions: read, and fail-closed recovery guidance. Head d765e0b7e85d062de0c7c33f41234e4dd21a9c46 changes eleven files and additionally carries unrelated trusted-uv materializer source/tests plus broad governance documents.

Rebuild from protected main so the effective diff is the six declared files only. Preserve materializer/governance work in its authoritative PR, update the stale exact-head identity in the body, then reacquire exact-head artifact-rerun, Strix, security, supply-chain, and independent-review evidence.

Review only exact current head 17327a23b75f00523c6ad409d8abebbed3a48397 against live protected main@6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba. I removed the unrelated trusted-uv production delta by restoring the exact SLSA/NIST attempt-scoped artifact tree as a new descendant. The current branch retains immutable artifact-ID + producer-attempt binding, fail-closed missing/expired evidence, one-day retention, credential-free actions: read, and the documented exact-head recovery contract. Exact-head checks are regenerating; nonterminal evidence is not acceptance. Review read-only; do not mutate source, synthesize approval, allow stale artifact fallback, weaken protection, or merge.

@seonghobae Review verdict for exact head 17327a23b75f00523c6ad409d8abebbed3a48397 against main@6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba:

The artifact handoff implementation passes the requested static semantic review.

  • coverage-source-tree exports the upload action’s immutable artifact-id.
  • The producer exports a validated github.run_attempt.
  • coverage-evidence requires the producer attempt to equal its current github.run_attempt.
  • The consumer validates a positive artifact ID before download.
  • The consumer downloads only through artifact-ids.
  • The consumer has only actions: read.
  • The handoff retains one-day evidence retention.
  • Producer, identity, and download failures reach the fail-closed recovery gate.
  • The recovery guidance requires a full rerun or a fresh repository dispatch.
  • I found no stale-artifact search or name-based fallback in the changed handoff path.

The exact head does not satisfy the stated six-file bounded scope. It changes nine files. The additional files are ARCHITECTURE.md, CLAUDE.md, and tests/test_materialize_base_python_requirements.py. These changes are outside the declared artifact-rerun repair.

The current checks do not support acceptance. GitHub reports queued, in-progress, cancelled, and skipped checks. GitHub reports mergeStateStatus: BLOCKED. I do not treat this evidence as a successful exact-head validation.

No source, workflow, protection, or merge state was changed.

Exact-current-head read-only review request for 5cf988c7aca0541fa7a6561c55667a52caf306ec over protected base 6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba.

A non-destructive forward commit restored the exact six-file previously bounded artifact-attempt tree; GitHub compare reports zero changed files from 498867cf05079120aa89c05fe1d13b65b26084a4. Recheck immutable artifact ID plus producer attempt binding, positive current-attempt validation before download, credential-free actions:read consumption, hard failure for missing/expired evidence, one-day retention, preserved exact-head/source/archive/isolation/coverage/docstring/security boundaries, and absence of stale fallback or temporary writers. Treat every predecessor check/review as historical. Do not mutate or merge the branch.

Unique-source replay of #928 onto origin/main.
Keep current changelog history. Coverage source evidence is bound to a
producer-attested attempt and immutable artifact ID; selective reruns fail
closed before download. Retarget the independent-review blob pin to the
attempt-scoped dispatch workflow.

테스트 이름과 docstring은 ordinary repair와 conflict repair의 동일한 scope를 요구합니다. 그러나 현재 assertion은 ordinary slice만 검사합니다. Conflict 경로에서 snapshot, sealed inventory, restore_workspace_config, 또는 verify가 제거되어도 테스트는 통과할 수 있습니다. conflict_start에서 conflict block을 추출하고 두 block에 동일한 assertion을 적용하세요.
