test(voyage): add annotation roundtrip + rollback + source_annotations integration — v4.2 Step 7
Implements SC2/SC3/SC5b/SC7 + additive-field invariant for the v4.2
annotation pipeline:
Fixtures (tests/fixtures/annotation/):
- annotation-brief.md — brief-validator-clean fixture
- annotation-plan.md — plan-validator-clean (2 steps)
- annotation-review.md — review-validator-clean
- annotation-plan-large.md — 51 steps (SC3 scale fixture)
Integration tests:
- tests/integration/annotation-roundtrip.test.mjs — 7 cases:
SC2 byte-identical empty round-trip across brief/plan/review,
SC3 scale (51 steps + 100 anchors) round-trip,
SC7 parseAnchors(stripAnchors(addAnchors(...))) === [] per target.
- tests/integration/schema-rollback.test.mjs — 4 cases:
SC5b validator-FAIL -> revisionGuard rolls back byte-identical
(sha256 invariant) for brief/plan/review + cross-target sweep.
.local.bak deleted on rollback path (validator-PASS path tested
in lib/util/revision-guard tests).
- tests/lib/source-annotations.test.mjs — 6 cases mirroring
tests/lib/source-findings.test.mjs additive-field pattern: each
validator (brief/plan/review) accepts source_annotations as
additive-optional, parser extracts as array of dicts, entries
conform to documented shape, baseline forward-compat (artifacts
without source_annotations still validate).
Verify: node --test tests/integration/annotation-roundtrip.test.mjs
tests/integration/schema-rollback.test.mjs
tests/lib/source-annotations.test.mjs -> 17 pass / 0 fail.
Full npm test: 577 pass / 0 fail / 2 skipped (Docker).
