- docs/SEARCH-QUALITY.md: the bake-off close record — corpus v1 (75 cases) x
gazetteer v1 (30 entries), measured 2026-10-23T17:02Z via npm run search:corpus
- top-1 66/68 (97.1%), top-3 68/68 (100.0%) >= 90% threshold
- negatives refused 7/7, refusal margin 0.643 < 0.72 admission line
- per-category table (landmark/abbreviation/glued/typo/alias all 100%)
- escalation lever: None — met on first run; no abbreviations.ts row, no
alias, no corpus edit; the fixed ladder was never climbed
- coordinate verification: 10 seed entries spot-checked against Nominatim
(identifying UA, 1 req/s): 8/10 within 0.01°; bukit-bintang outlier is an
area-vs-point discrepancy (no change); pavilion-kl was a real ~2 km error
- both top-1 misses documented as expected disjoint-tier behaviour
- kl-gazetteer.json: pavilion-kl coordinate corrected (3.1478,101.695) ->
(3.149,101.7132) — Rule 1 data bug found by the prescribed Nominatim
verification; post-fix delta 0.0002°; corpus is coordinate-blind, all suites green
