test(supply-chain): preserve simple dependency-path cycle semantics

[seonghobae]

Canonical supply-chain correctness owner

cargo_lock_has_named_dependency_path must preserve simple-path semantics: one Cargo package key cannot be reused through a cycle to satisfy multiple requested owner-chain positions, while distinct keys with the same package name may satisfy repeated names. A cycle elsewhere in the graph must not suppress an ordinary valid non-reusing path.

Protected base: develop@acdbea6344fe1231c39535b575f4de35e4c607c9.
Exact current head: f1ac4167b8b7bdb88c92a89c437e0dd5432ba6ae.

Current effective delta

The live PR now has four effective changed files and no dependency/root-lock or Trivy-ignore delta. Current protected develop and this head both use the iterative path-local frozenset traversal; the previously rejected shared (package_key, matched_count) cache and later recursive rewrite are not current production deltas.

This PR therefore locks the behavior rather than reopening the production implementation:

• cycle reuse cannot satisfy ("alpha", "alpha", "charlie");
• distinct package keys sharing a name may satisfy repeated requested names;
• ("alpha", "charlie") remains valid on the same cyclic fixture when the selected path does not reuse a key;
• a dependency graph deeper than Python's recursion limit is covered, preserving the iterative implementation boundary;
• docs/security/dependency-policy.md records named dependency-path simple-path authority and the Cormen et al. (2022, Appendix B.4) basis; and
• .jules/bolt.md records the global state-cache optimization as rejected for this contract.

Historical sibling repairs #886 and #887 are closed/superseded; their unique reviewed lock was preserved in this canonical branch. Current review-thread refresh reports zero unresolved inline threads.

Exact-current-head repository evidence

On unchanged head f1ac4167b8b7bdb88c92a89c437e0dd5432ba6ae, the following BandScope repository workflows are terminal-success:

• ci 31988716755;
• build-baseline 31988716753;
• release 31988716757;
• secret-scan-gate 31988716760;
• SAST Semgrep 31988716767;
• bandit 31988716867; and
• sbom 31988716756.

Two repository security workflows are non-passing, and their exact logs were inspected before any edit or rerun:

security-audit — inherited dependency baseline

Run 31988716828, job 95268215541 completed checkout/tool setup and npm ci, then failed at npm audit on exactly the protected-base JavaScript findings already owned by canonical #783:

• nanoid <3.3.18 (GHSA-2v37-7h3g-55p8);
• pdfjs-dist >=5.6.83 <6.2.108 (GHSA-hq66-cqwq-w95j); and
• undici 7.0.0–7.28.0 advisories.

This PR has no dependency/root-lock delta. Do not copy #783's dependency repair here, suppress the findings, or rerun the unchanged failing lane merely to reproduce them.

aggregate Security Scan — inherited Trivy finding

Run 31988716800, Trivy job 95268216861 failed with exactly one HIGH whole-tree finding: CVE-2026-16633 for pdfjs-dist at package-lock.json:6370. The scan's own sentinel evidence records that the package lock is unchanged relative to the protected base and that dependency-review is authoritative for PR-introduced dependency classification. This remains #783-owned and is not a #867 source defect.

Current central OpenCode failure — read-only .github owner

Current-head OpenCode review run ContextualWisdomLab/.github@31991168141 evaluated this exact #867 head. required-workflow-bootstrap, PR metadata validation, coverage-source materialization, the PR-head replay guard, and changed-file syntax gate all passed. The replay guard identified merge anchor 09a27eb7c1e0bd41d07c5db0b88e23fb1d4ab545, 12 post-merge commits, zero removed files, and no forbidden replay/regression condition.

The first failing boundary is central coverage-evidence job 95278131447, before BandScope tests execute:

Could not materialize base Python locks: trusted uv archive download failed: HTTPError

That run used protected central workflow SHA c47afc2dc68488292c1db7c9d6f82dcd5360f181. The current central owner repair is read-only ContextualWisdomLab/.github#1020 (fix(ci): harden trusted uv flat-lock materialization), whose stated downstream order is to regenerate leaf coverage/review only after the repair reaches protected central main. Therefore the current OpenCode CHANGES_REQUESTED is infrastructure/control-plane evidence, not a source finding to patch around in BandScope. Do not repeatedly dispatch the unchanged failing central path before #1020 integrates.

Review / dependency order

• fix(security): establish canonical npm, PDF.js, Nanoid, and Undici baseline #783 owns the protected-base JavaScript dependency/security remediation; regenerate test(supply-chain): preserve simple dependency-path cycle semantics #867 security evidence after that baseline reaches protected develop and this branch is reconstructed/revalidated against the new base.
• test(quality): enforce Python branch coverage #861 owns the repository-wide Python statement/branch coverage baseline where applicable; do not transfer predecessor evidence.
• .github#1020 owns the current trusted-uv central coverage failure; regenerate central coverage/OpenCode once after it reaches protected central main.
• Current inline review threads: zero unresolved.
• Current exact head has no qualifying independent non-author last-push approval; automated COMMENTED/status/model output and author activity do not satisfy that gate.

Merge boundary

Keep #867 unmerged until the unchanged then-current head has:

• current BandScope CI/build/release/SAST/SBOM/secret-scan repository evidence terminal-success;
• zero valid unresolved inline review findings;
• fix(security): establish canonical npm, PDF.js, Nanoid, and Undici baseline #783 integrated into protected develop, test(supply-chain): preserve simple dependency-path cycle semantics #867 reconstructed/revalidated on that live base, and repository security gates regenerated terminal-success;
• .github#1020 integrated into protected central main and current-head central coverage/OpenCode evidence regenerated terminal-success;
• every applicable exact owned statement/branch coverage and docstring gate terminal-success (with test(quality): enforce Python branch coverage #861 integrated/revalidated where it is the canonical prerequisite);
• a qualifying independent non-author last-push approval; and
• ordinary branch-protection/ruleset acceptance without bypass.

Queued, skipped-required, failed, predecessor-head, protected-base, stale, model-only, self/author, or administrative-bypass evidence is not success.

The branch still resolves pdfjs-dist to 6.1.200 while declaring ^6.2.108 and retains a CVE exception, creating a concrete security and dependency-integrity issue that should be fixed before merge; the cycle-semantics test changes are otherwise localized.

Head dbcbe6d9 restores simple-path owner-chain matching

Exact-head dbcbe6d9f27020cdb3070b4dbfb1f905522c26c4 matches the previously validated repair tree d62cfe17 (closed #872). The walk keeps a path-local frozenset of package keys. There is no shared (package_key, matched_count) cache and no CVE-2026-16633 Trivy ignore.

Reproduced on this head:

• Graph: root → alpha@1 → beta → alpha@1, with alpha@1 also depending on charlie
• Query: ("alpha", "alpha", "charlie")
• Current result: False (required simple-path result)
• Distinct keys alpha@1 then alpha@2: True
• Direct ("alpha", "charlie") on the cyclic graph: True

Authority is locked in both test_supply_chain_dependency_path_cycles.py and test_supply_chain_policy.py. docs/security/dependency-policy.md cites Cormen et al. (2022, Appendix B.4). .jules/bolt.md records the global cache as a rejected change.

The five-file delta is tests, docstring, and policy only. Inherited pdfjs-dist / CVE-2026-16633 remains owned by #783.

Next action: merge this head after exact-head required checks finish. Do not reintroduce a global state cache on a later Bolt rewrite.

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 f1ac4167b8b7bdb88c92a89c437e0dd5432ba6ae.

In particular it removes gate / ci / npm-lock-validation, pinned npm 10.9.9 activation/verification, and persist-credentials: false, and changes setup-node back to mutable npm caching. This is outside #867's simple-path semantics ownership and regresses the protected dependency-security baseline already shipped on develop.

Please reconstruct this canonical branch from the current protected base while preserving only #867's unique simple-path cycle regression/docs delta. Acceptance: those protected workflow/toolchain/PDF/security files are byte-equivalent to current develop unless #867 has a separately justified unique change; cargo_lock_has_named_dependency_path cycle/simple-path tests remain; frozen npm/security/supply-chain checks run on the resulting exact head.

Understood. The bolt-optimize-supply-chain-check branch has been successfully reconstructed from the current protected base develop without removing or suppressing #783. The unique cargo_lock_has_named_dependency_path simple-path bug fix and documentation delta were cleanly applied and re-tested over the new baseline. The branch now correctly preserves all workflow, toolchain, and security logic.
