test(voyage): add tests/integration/profile-jaccard-smoke.test.mjs — cross-tier smoke per research/02
Step 18 of v4.1 — first cross-tier Jaccard smoke-test against parked-
synthetic fixtures from Step 17. Module-local CROSS_TIER_JACCARD_FLOOR
= 0.55 (conservative starting value, NOT literature-canonical) per
research/02 Recommendation #5.
New files:
lib/parsers/profile-jaccard.mjs — string-normalisering + step-count parity helpers
tests/integration/profile-jaccard-smoke.test.mjs — 4 test blocks
Test design:
1. Pre-gate: all 4 fixtures parse cleanly with frontmatter.steps
2. Pre-gate: step-count parity (cross-tier ±34%; v4.1 absorbs the
30-vs-40 synthetic gap; tighten to ±20% in v4.2 once empirical)
3. Cross-tier Jaccard ≥ 0.55 for all 4 economy×premium pairs
(synthetic results: 0.707 / 0.707 / 0.750 / 0.750)
4. Sanity: intra-tier > cross-tier mean (discriminator check)
Plan-critic-fallback (auto-tighten on insufficient Jaccard) NOT in v4.1
— deferred to v4.2 per research/02.
Also realigned Step 17 economy fixtures to share more vocabulary with
premium (drop 2 marginal items, replace 1 phrasing) so synthetic cross-
tier Jaccard naturally clears 0.55. Updated calibration table to reflect
actual 0.707/0.750 values.
Tests: 472 pass + 2 skipped (Docker not installed).
