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).

// String-normalisering helper for cross-tier Jaccard smoke-test (Step 18).
|
|
//
|
|
// Plan steps from different model tiers (sonnet vs opus) often differ
|
|
// only in punctuation, casing, or trivial wording (`logger.info` vs
|
|
// "logger.info" vs `logger info`). To avoid trivial false-negatives in
|
|
// cross-tier Jaccard, every step title passes through `normalizeStep`
|
|
// before set membership is computed.
|
|
//
|
|
// Normalisering rules (per research/02 §3.4):
|
|
// 1. Lowercase the entire string.
|
|
// 2. Strip backticks and parentheses (`...` and (...)).
|
|
// 3. Collapse runs of whitespace to a single space.
|
|
// 4. Trim leading + trailing whitespace.
|
|
//
|
|
// We do NOT stem or lemmatize — that would over-normalize and mask real
|
|
// disagreement (e.g. "Add tests for X" vs "Verify tests for X" should
|
|
// remain distinct).
