Restore path-local frozenset prevention, keep the cycle and distinct-key regressions in two test modules, drop the unauthorized pdfjs-dist Trivy ignore, and record the unsafe optimization as a rejected change.

I reproduced the three fixtures on this DFS head: cycle

Preserve the canonical #867 repair while incorporating #887's additional regression that makes the documented simple-path/Cormen authority executable. The resulting tree is exactly #887's reviewed tree; both sibling repair histories remain explicit parents so no unique evidence-bearing delta is discarded.

Head 09a27eb7 restores simple-path owner-chain matching
Exact head 09a27eb7c1e0bd41d07c5db0b88e23fb1d4ab545 is the merge of f270d3df and 593b6fe6. The tree matches closed #887. The matcher is still the iterative path-local frozenset walk. A cycle cannot reuse alpha@1 to satisfy ("alpha", "alpha", "charlie"). Distinct keys (alpha@1 then alpha@2) still match. The bcf22eea recursive-DFS rewrite and the deleted cycle/citation locks are gone. The policy-authority test is present and executable.
Independently reproduced on this walk:
- cycle
("alpha", "alpha", "charlie")→ False - distinct keys → True
- direct
("alpha", "charlie")on the cyclic graph → True
No lockfile, .trivyignore, or CVE-2026-16633 change. Inherited pdfjs-dist stays with #783.
Next action
Add one assert in test_supply_chain_dependency_path_cycles.py: on the existing cycle graph, ("alpha", "charlie") must stay True. The PR body claims that lock; the files do not have it. An implementation that rejects every cyclic graph would still pass today. That lock is the only remaining test gap on this slice.
Do not merge until exact-head required checks are terminal-success. Queued ci, Security Scan, rust-check, and macOS baseline jobs are not success. Windows amd64/arm64 already succeeded on this SHA. Do not treat this review as a substitute for those gates. #886 and #887 stay closed.
