Three TDD-first fixes surviving the B8 roadmap bucket (v8.0.0-plan.local.md
Phase 1, items 1-3; item 4 JAR hardening scoped out at review):
- supply-chain-recheck.mjs parseYarnLock: ported the hook's per-entry parser
(pre-install-supply-chain.mjs) so Berry's `version: x` format (unquoted) is
recognized alongside Classic's `version "x"` — Berry lockfiles previously
yielded zero deps, silently missing pinned compromised packages.
- supply-chain-recheck.mjs parsePackageLock: lockfileVersion-1 fallback now
recurses nested `dependencies`, mirroring the hook's walk() — a transitive,
non-hoisted compromised copy below the top level was previously invisible.
- content-extractor.mjs stripInjection: attribution moved from a global
`Set<label>` to `Set<label::lineIndex>`. The old check silenced the
unstripped flag for ANY occurrence of a label once ANY occurrence had been
line-redacted, so a second, cross-line-only encoded occurrence of the same
label survived into sanitized output without being flagged.
Full suite 2019/2019 (one known-flaky timing test confirmed green in isolation).
