| Baseline | Class | Headline |
|---|---|---|
search-quality-baseline-v1.2.0.md | A + B (canonical lookup + framework root) | MRR 0.9467, P@1 perfect on 46/50 |
search-quality-deprecation-baseline-v1.2.0.md | E (deprecation-aware) | Swift wins 30/30, sign-test p = 0.0078 |
search-quality-crosssource-baseline-v1.2.0.md (this doc) | F (cross-source canonical) | 19/19 OK when expected source present in top-10, p = 1.9 × 10⁻⁶. 6/25 reveal that HIG/apple-archive are systematically out-competed by apple-docs (by design). |
