Purpose

Restore exact-head security evidence for organization-required repository scanners and fail closed when dependency-review evidence is unavailable. DiskSage PR #137 exposed synthetic-merge scanner input; the public EgressWeave canary exposed a separate fail-open path where HTTP 403 skipped dependency review while the aggregate Security Scan remained green.

Exact current stack

  • exact head: a6cd746e86c07452d03e0f5cef8e8d13c22f28c6;
  • protected base/main: e71fdab2ab088001f218765ecb5e3b7fabfee11a;
  • main is an ancestor and GitHub reports the seven-file slice mergeable;
  • every temporary repair workflow, encoded patch, and unrelated process-group repair is absent;
  • predecessor-head checks and reviews are stale.

Implemented boundary

  • Dependency-review support, Trivy, and Scorecard check out the explicit pull-request head repository and immutable head SHA with persisted credentials disabled.
  • Trivy and Scorecard SARIF uploads bind refs/pull/<number>/head and that same exact head SHA.
  • The dependency-review support probe binds exact base and head SHAs and accepts only a transport-successful HTTP 200 response.
  • The support probe has a 10-second connection limit and 30-second total limit; timeout, partial transfer, transport failure, HTTP 403/404, 000, empty/malformed status, and every unexpected outcome fail closed.
  • The API response body is discarded to /dev/null; diagnostics expose only bounded repository, base/head identity, and status evidence.
  • Only the successful probe enables the immutable-pinned actions/dependency-review-action hard gate; no green supported=false path exists.
  • OSV, Trivy, CodeQL, Semgrep, Secret Scan, Scorecard, Dependabot, and dependency review remain independent controls.
  • Fork pull requests remain read-only and supported through their explicit head repository.

Exact-head acceptance evidence

For a6cd746e86c07452d03e0f5cef8e8d13c22f28c6, all exact-head workflows completed successfully:

  • Security Scan Exact-Head Quality CI 31153100905;
  • Security Scan 31153100932;
  • CodeQL PR 31153100875;
  • Python Security 31153100955;
  • SAST Semgrep 31153100913;
  • Secret Scan 31153100874;
  • OSV-Scanner PR 31153101198;
  • Scorecard PR 31153100952;
  • SBOM Generation 31153100999;
  • CodeRabbit commit status: success.

All inline review threads are resolved or outdated; zero actionable unresolved thread remains. Formal exact-current-head OpenCode/Noema review and a qualifying independent non-author approval remain required. Queued, cancelled, predecessor-head, synthetic-merge, status-only, author-only, local-only, or repair-workflow evidence is not accepted.

Stack order

This scanner repair overlaps the fail-closed dependency-review subset carried by .github#813, whose primary purpose is the OpenCode fatal-process-group prerequisite. Keep this PR Draft until #813 reaches protected main. Then rebase or merge the new protected base, remove any base-identical overlap from the effective diff, and regenerate every exact-head quality, security, review, and approval surface. No evidence transfers across that base change.

Operator and merge contract

For a public GitHub.com repository, unavailable dependency-review evidence is a repository/organization configuration or capability problem until proven otherwise. Correct dependency graph, GitHub security capability, organization policy, entitlement, or token access and rerun; do not manufacture a green check by weakening the hard gate. Private/internal exceptions require explicit organization policy and independently reviewable entitlement evidence.

docs/doctoring/security-scan-exact-head.md records exact-head authorization, SARIF identity, fail-closed behavior, bounded execution, rollback, operator remediation, and APA 7 primary sources. After #813 integration and this PR's base refresh, merge only after exact-current-head automated review, qualifying independent non-author approval, zero unresolved valid findings, and every branch-protection rule succeed without bypass.

@opencode-agent Extend this exact-current-head security-scan repair test-first to address #810, and do nothing if PR #799 branch head is no longer aee317b3ecbfaad7cdb3898e603dfe5e69b8f7ae.

A downstream exact-head canary exposed a valid organization-level fail-open defect in the same workflow. ContextualWisdomLab/EgressWeave is public. On EgressWeave PR #66 exact head c038a9509d1a8eae8561cc9081e67e12bd373d42, Security Scan run 31108241013, dependency-review job 92638903658, the exact compare 10d0c51daf2ad278d66f43be479df8cf6b08ba6d...c038a9509d1a8eae8561cc9081e67e12bd373d42 returned HTTP 403; central security-scan.yml warned that dependency review was unavailable, set supported=false, skipped actions/dependency-review-action, and returned a green job/workflow. GitHub currently documents dependency review/action as available for public GitHub.com repositories when dependency graph is enabled, and the public-resource REST compare does not require authentication. Treat this as unavailable security evidence, not a clean dependency review. Do not guess the root cause of the 403.

Use two auditable commits in order:

  1. Immutable RED test-only commit. Modify only tests/test_security_scan_exact_head.py (or add one tightly focused tests/test_security_scan_dependency_review.py if substantially clearer). Add a deterministic static/contract regression that fails on current head because 403/404 are converted to supported=false + exit 0 / success and because the hard action is conditionally skipped. Require the central contract to distinguish an executed clean review from API unavailability and to fail closed for public-repository unavailability. Preserve all existing exact-head checkout and SARIF contracts.

  2. GREEN bounded repair. Modify only .github/workflows/security-scan.yml, the focused test above, docs/doctoring/security-scan-exact-head.md, and CHANGELOG.md. For the dependency-review support probe:

    • keep exact BASE_SHA/HEAD_SHA, exact PR-head checkout, read-only permissions, persisted credentials disabled, and the immutable actions/dependency-review-action@a1d282b36b6f3519aa1f3fc636f609c47dddb294 pin;
    • 200 may continue to the hard dependency-review action;
    • 403, 404, empty/malformed status, curl/transport failure, timeout, and any unexpected status must not yield a successful dependency-review result for a public repository; fail closed with a concise actionable error that identifies repository plus exact base/head and HTTP status but does not print auth material or an untrusted response body;
    • do not use OSV, Trivy, Scorecard, CodeQL, or another scanner as a semantic substitute for dependency review;
    • do not introduce branch-controlled opt-outs or infer not-applicable from 403/404. If private/internal repository exceptions are required, leave that as the separately governed policy decision in security: make central dependency-review unavailability fail closed #810 rather than weakening this public-repository canary repair.

Update doctoring so its claimed fail-closed behavior matches production and include current APA 7 primary references to GitHub Dependency Review, Dependency Graph, and Dependency Review REST API. Add one concise [Unreleased] Security entry; no version/release bump.

Do not change .github/workflows/security-scan-exact-head-quality-ci.yml unless the existing permanent exact-head quality job cannot discover the new focused test without a minimal dependency-free update. Do not modify any other workflow, OpenCode/Noema/Strix credentials or identities, dependencies, repository protections, publication/release/tag/ref behavior, model provider, or caller. Never add a temporary/self-modifying/write-capable repair workflow, contents: write, OIDC, branch push, merge/rebase, auto-merge, -X ours/theirs, or execution of model-modified source under a write credential.

After GREEN, run the focused dependency-free contract and the complete central Python test/100% statement+branch coverage/public-docstring/compile contract available on the branch. Then leave PR #799 unmerged and request fresh exact-GREEN CodeRabbit/OpenCode/Noema review plus every required security workflow; do not claim queued, absent, skipped, predecessor-head, or synthetic-merge evidence as current-head success. Report immutable RED and GREEN SHAs in this PR conversation.

@opencode-agent Extend this existing security-scan repair test-first on exact current head aee317b3ecbfaad7cdb3898e603dfe5e69b8f7ae; stop without writing if the head differs.

Fresh downstream evidence from ContextualWisdomLab/EgressWeave#66 exact head c038a9509d1a8eae8561cc9081e67e12bd373d42 exposed a still-valid organization-level fail-open dependency-review path. Security Scan run 31108241013, job 92638903658, queried exact base 10d0c51daf2ad278d66f43be479df8cf6b08ba6d and exact head c038a9509d1a8eae8561cc9081e67e12bd373d42; the dependency-graph compare endpoint returned HTTP 403. The current central step then emitted Dependency review is unavailable for ContextualWisdomLab/EgressWeave; skipping dependency-review hard gate., set supported=false, skipped actions/dependency-review-action, and allowed the dependency-review job and aggregate Security Scan to conclude success. This is tracked as ContextualWisdomLab/EgressWeave#76. PR #66 does not change dependency inputs, so do not claim it introduced a vulnerable dependency; repair the assurance semantics instead.

Use the existing PR #799 rather than creating a competing PR because it already owns .github/workflows/security-scan.yml, its exact-head contracts, doctoring, and CHANGELOG. Preserve the exact-head checkout/SARIF repair already present.

Required RED → GREEN extension:

  1. First commit immutable test-only RED evidence in the existing security-scan contract tests proving that HTTP 403/404 from dependency-review support cannot be represented as a passed dependency-review gate.
  2. Preserve 200 as the only path that may execute the pinned dependency-review action.
  3. For unavailable 403/404, classify the exact PR base..head conservatively and deterministically. If any supported dependency manifest, lock, dependency-submission definition, package-resolution input, or an unknown/truncated classification state is present, fail closed. If and only if the complete exact diff proves no dependency-sensitive path changed, emit an explicit exact-base/exact-head not-applicable outcome; never call that passed.
  4. Any GitHub API enumeration used for classification must paginate fully, bind repository/PR/base/head identities, reject stale heads, and fail closed on malformed responses, page/record limits, truncation, rate/permission failures, or identity drift. Prefer an already-authenticated exact-tree method if it gives stronger completeness evidence. Do not rely on the capped compare-file list as complete evidence.
  5. Keep contents/pull-requests read-only, persist-credentials: false, immutable action pins, fork-read-only behavior, OSV, Trivy, Scorecard, CodeQL/GHAS, Semgrep, Dependabot and existing scanner semantics unchanged except for the corrected dependency-review outcome.
  6. Add focused positive/negative/adversarial tests for dependency-sensitive paths, dependency-neutral paths, stale-head refusal, pagination/completeness, malformed/unavailable responses, and the exact EgressWeave 403 shape. Maintain 100% production statement/branch coverage and beginner-readable public docstrings for any helper added.
  7. Update docs/doctoring/security-scan-exact-head.md with passed vs exact-bound not-applicable vs unavailable/fail-closed, administrator remediation for enabling GitHub dependency graph/Code Security when entitlement permits, and APA 7 primary GitHub references. Prepend one [Unreleased] Security entry; do not bump a version.

Modify only the already-owned PR #799 security-scan workflow/contract/helper/documentation/CHANGELOG surface needed for this repair. Do not add any repository-write, OIDC, branch/ref publication, PR creation/merge, release/package/signing authority, temporary write-capable workflow, self-modifying workflow, model-modified-tree publication, or conflict strategy. Do not merge or mark Ready. After GREEN, require fresh exact-current-head central quality/security/review evidence and preserve independent non-author approval and branch protection as mandatory gates.

@seonghobae Formal exact-head review completed for aee317b3ecbfaad7cdb3898e603dfe5e69b8f7ae against main f070c504c1cb06891b800d7ab0cf6ac7d3cf8eae.

Finding — P1: dependency-review can succeed without dependency-review evidence

In .github/workflows/security-scan.yml, Line 292 through Line 295 convert dependency-graph compare HTTP 403 or 404 into supported=false and exit successfully. Line 302 then skips the pinned actions/dependency-review-action. The dependency-review job and the required Security Scan workflow can therefore pass without a dependency review.

Treat unavailable support as unavailable security evidence. Fail the job with a concise error that identifies the repository and exact base/head. Do not print the response body. This behavior is relevant to the reported EgressWeave public-repository 403 case.

The remaining requested controls are present:

  • Dependency review, Trivy, and Scorecard check out github.event.pull_request.head.repo.full_name at github.event.pull_request.head.sha.
  • These checkouts set persist-credentials: false.
  • Trivy and Scorecard SARIF uploads bind refs/pull/${{ github.event.pull_request.number }}/head and github.event.pull_request.head.sha.
  • Trivy preserves the fixable CRITICAL,HIGH,MEDIUM hard gate.
  • Scorecard remains a soft job.
  • Workflow permissions remain least-privilege for the scanner roles.
  • GitHub reports the named quality, security, review, and SBOM workflows as successful for the requested head.

I cannot approve while the dependency-review fail-open path remains.

@opencode-agent Exact-head correction for #810: extend only current PR #799 head 323c07b794d11f82c04db91544bc3a3f5cf5ad5c; stop without writing if the branch head differs. The prior #810 request was intentionally bound to stale predecessor aee317b3ecbfaad7cdb3898e603dfe5e69b8f7ae and therefore must not authorize a write now.

Preserve the existing exact-PR-head checkout/SARIF binding repair. Add the dependency-review availability repair test-first in two auditable commits:

  1. Immutable RED, test-only: add a focused deterministic contract proving the current 403/404supported=false/exit-0 → skipped hard action → green aggregate path is forbidden. Preserve all existing exact-head contracts.
  2. GREEN bounded repair: modify only .github/workflows/security-scan.yml, that focused test, docs/doctoring/security-scan-exact-head.md, and CHANGELOG.md (and leave the permanent quality workflow unchanged unless discovery truly requires a minimal dependency-free adjustment). A 200 support probe may continue to the immutable-pinned dependency-review action. For a public repository, 403, 404, empty/malformed status, transport/curl failure, timeout, truncated state, or any unexpected status must fail closed with concise repository + exact base/head + status diagnostics, without auth material or untrusted response bodies. Do not substitute OSV, Trivy, Scorecard, CodeQL, Semgrep, or another scanner for dependency review. Do not infer not-applicable from 403/404 or add a branch-controlled opt-out.

Keep exact BASE_SHA...HEAD_SHA binding, explicit head repo/SHA checkout, persist-credentials: false, read-only permissions, immutable action pins, and the independent scanner surfaces. Add current APA 7 primary GitHub references and one [Unreleased] Security entry; no version bump.

Do not add or use a temporary/self-modifying/write-capable workflow, contents: write, OIDC, branch push, merge/rebase, auto-merge, -X ours/theirs, or execution of model-modified source under a write credential. After GREEN, run the focused dependency-free contract and complete central test/100% statement+branch coverage/public-docstring/compile contract, then request fresh exact-GREEN review and required security workflows. Report immutable RED/GREEN SHAs and exact-head evidence; do not merge or publish.

Final read-only review for exact head 323c07b794d11f82c04db91544bc3a3f5cf5ad5c. Exact-head quality, CodeQL, Python Security, SAST, Security Scan, Secret Scan, OSV, Scorecard, and SBOM are successful. Verify literal contributor-head checkout and SARIF identity binding for dependency-review support, Trivy, and Scorecard, including fork read-only behavior and persisted-credential denial. Submit a qualifying non-author approval only if no actionable finding remains. Do not mutate the branch, bypass protections, or merge.

@seonghobae Formal exact-head review completed for 323c07b794d11f82c04db91544bc3a3f5cf5ad5c.

Finding — P1: dependency-review can pass without dependency-review evidence

In .github/workflows/security-scan.yml, Line 292 through Line 295 handle HTTP 403 or 404 by setting supported=false and exiting successfully. Line 302 then skips the pinned actions/dependency-review-action. The dependency-review job and the aggregate Security Scan workflow can therefore pass when dependency-review evidence is unavailable.

The exact head still contains the EgressWeave fail-open path from the prior review. Treat 403, 404, malformed status, transport failure, and unexpected status as unavailable security evidence. Fail the job with a concise diagnostic that includes the repository, BASE_SHA, HEAD_SHA, and HTTP status. Do not print credentials or the response body.

The requested exact-head controls are present:

  • Dependency review, Trivy, and Scorecard use github.event.pull_request.head.repo.full_name and github.event.pull_request.head.sha.
  • These checkouts set persist-credentials: false.
  • Trivy and Scorecard SARIF uploads bind refs/pull/${{ github.event.pull_request.number }}/head and github.event.pull_request.head.sha.
  • The workflow keeps read-only contents and pull-requests permissions for dependency review.
  • Trivy retains the fixable CRITICAL,HIGH,MEDIUM hard gate.
  • Scorecard remains a soft posture job.
  • The listed quality, security, and supply-chain workflows completed successfully for the requested SHA.

I cannot approve while the dependency-review fail-open path remains.

Supersede the immediately preceding review-only request at issue comment 5210969307 for current head 323c07b794d11f82c04db91544bc3a3f5cf5ad5c. It was generated against a tree that still contains the #810 fail-open dependency-review path and therefore must not be treated as a final-approval request or as evidence that all security/supply-chain gates are trustworthy.

Current-head inspection still shows .github/workflows/security-scan.yml converting dependency-review support-probe HTTP 403/404 into supported=false + exit 0 and conditionally skipping the pinned dependency-review action. The exact-head test-first repair request in comment 5210837930 remains the active mutation instruction for this branch. Do not approve, merge, auto-merge, release, or publish 323c07b794d11f82c04db91544bc3a3f5cf5ad5c as-is.

After a new exact GREEN head implements #810, request fresh CodeRabbit/OpenCode/Noema review and every required quality/security/supply-chain workflow against that new SHA only. Predecessor-head success and this superseded review request are stale evidence.

@seonghobae Formal read-only review completed for PR #799 at exact head e7690e359791353fb5547e1b4a4d1e4272f78cc3 against base e6fc91416c4fb13febd07b985c6e9c74fe888306.

I found one blocking current-head defect. I cannot approve this head.

P1 — The central test contract still requires the removed fail-open path.

tests/test_required_workflow_queue_contract.py, Lines 829-838, defines test_security_scan_skips_dependency_review_when_dependency_graph_is_unavailable. It requires .github/workflows/security-scan.yml to contain:

  • "$status" = "403"
  • "$status" = "404"

The current workflow correctly contains neither branch. It accepts only HTTP 200. It exits with failure for every other result. The central test contract therefore contradicts the fail-closed dependency-review boundary. It will fail during the complete central test suite.

Replace this legacy test with a fail-closed contract that requires:

  • the exact ${BASE_SHA}...${HEAD_SHA} comparison;
  • only HTTP 200 to emit supported=true;
  • the immutable actions/dependency-review-action@a1d282b36b6f3519aa1f3fc636f609c47dddb294 action to remain gated on that output; and
  • no supported=false output or successful skip for 403, 404, malformed or empty status, timeout, transport failure, or any other non-200 result.

The other inspected controls are correct on this exact head:

  • Dependency review, Trivy, and Scorecard check out the explicit pull-request head repository and SHA with persisted credentials disabled.
  • The dependency-review probe uses the exact base/head identity.
  • The probe uses --connect-timeout 10, --max-time 30, and -o /dev/null.
  • The non-200 diagnostic contains repository, base SHA, head SHA, and status. It does not print the API response body or token.
  • Trivy and Scorecard SARIF uploads bind refs/pull/<number>/head and the exact head SHA.
  • The immutable action pin, read-only permissions, fork-compatible checkout behavior, Trivy gate, and Scorecard soft role remain intact.
  • The focused contracts, doctoring, README, and changelog match the production fail-closed behavior.
  • No temporary timeout patch artifact exists.
  • The review-thread query returned no unresolved threads.

The focused workflow can pass while the complete central suite still fails on the stale contract. Keep the PR unapproved until that test is repaired and the complete suite passes on a new exact head.

@opencode-agent Implement the minimal test-only GREEN repair on exact current head e7690e359791353fb5547e1b4a4d1e4272f78cc3 of branch fix/security-scan-exact-head; stop without writing if the live head differs.

The current exact-head OpenCode coverage run 31148891881 failed because tests/test_required_workflow_queue_contract.py::test_security_scan_skips_dependency_review_when_dependency_graph_is_unavailable still asserts the superseded fail-open HTTP 403/404 behavior. The exact production workflow intentionally accepts only HTTP 200 and exits nonzero for every unavailable status. The focused exact-head contracts already encode that boundary, and a local reproduction on the materialized exact tree produced exactly one failure in this stale test; after the bounded test correction, the three relevant files reported 54 passed.

Modify only tests/test_required_workflow_queue_contract.py:

  • rename the stale test to test_security_scan_fails_closed_when_dependency_graph_is_unavailable with a normal -> None signature;
  • retain the support-step ID, exact base/head compare endpoint, and supported-output gate assertions;
  • replace the 403/404 acceptance assertions with assertions for if [ "$status" != "200" ]; then, absence of supported=false, absence of skipping dependency-review hard gate, and presence of HTTP ${status:-unavailable}.

Do not modify the production workflow, dependencies, docs, credentials, permissions, refs, release paths, or any other file. Run the corrected contract file plus tests/test_security_scan_exact_head.py and tests/test_security_scan_sarif_exact_head.py, then run the repository's complete Python coverage/docstring contract if available. Commit only the single test-file repair. Do not merge, approve, mark draft, rebase, retarget, release, or publish.

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 a6cd746e86c07452d03e0f5cef8e8d13c22f28c6.

  • Head SHA: a6cd746e86c07452d03e0f5cef8e8d13c22f28c6

Verify the durable diff binds dependency-review, Trivy, and Scorecard to the literal PR head, fails dependency-review availability closed unless the exact base/head probe returns HTTP 200, applies explicit connect/total timeouts, discards the response body, binds SARIF to the exact head identity, preserves independent scanner controls, and contains no temporary/encoded/write-capable repair workflow or patch payload. Exact-head Security Scan Exact-Head Quality CI, Security Scan, Python Security, CodeQL, Semgrep, Secret Scan, OSV, Scorecard, and SBOM runs are all successful on this head. Anchor any formal outcome to this exact PR/head.

/oc Refetch the live pull request and stop without writing unless its exact head is a6cd746e86c07452d03e0f5cef8e8d13c22f28c6. Keep the PR Draft. Exact-head OpenCode run 31153541779 failed only because inherited tests/test_required_workflow_queue_contract.py::test_security_scan_skips_dependency_review_when_dependency_graph_is_unavailable still asserts the superseded fail-open 403/404 support path, while .github/workflows/security-scan.yml now correctly accepts only HTTP 200 and fails closed for every unavailable, malformed, timeout, transport, 403, 404, or unexpected result.

Apply the minimum test-only repair. Rename that test to describe fail-closed dependency-review evidence. Preserve assertions for id: dependency_review_support, the exact ${BASE_SHA}...${HEAD_SHA} dependency-graph endpoint, and the gated action condition. Replace the obsolete "$status" = "403" and "$status" = "404" assertions with bounded assertions proving: curl has 10-second connect and 30-second total timeouts; only if [ "$status" != "200" ]; then is accepted; the non-200 branch emits the bounded exact-base/head error and exits 1; supported=true is written only after that branch; and there is no supported=false output or green skip path. Do not add inert workflow strings merely to satisfy the old test and do not change production scanner behavior.

Run that focused test first, then tests/test_security_scan_exact_head.py, tests/test_security_scan_sarif_exact_head.py, the full repository suite, the exact PR quality workflow, 100% production statement/branch coverage and public docstrings where configured, compileall, and git diff --check. Update the PR body's exact-head evidence after the commit. Do not mark Ready, approve, merge, release, force-push, create another branch/PR/workflow, or alter reviewer credentials, NVIDIA_NIM_API_KEY, or any model-provider boundary. Never introduce COPILOT_GITHUB_TOKEN.
