Back to Search-quality baseline: CamelCase fragment recall (Phase 1.3, v1.2.0 candidate)

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` | F (cross-source canonical) | 19/19 OK when expected source in top-10, p = 1.9 × 10⁻⁶
`search-quality-fragment-baseline-v1.2.0.md` (this doc) | D (CamelCase fragment) | mean P@1 = 1.0, mean P@5 = 0.92 across 20 fragment queries. 14 / 20 returned 5/5 matches. The #77 symbol_components mechanism is working.

Four of eight Phase 1.x classes from §1.4 now have documented baselines. Four remain: C (acronym), G (prose), H (symbol-attribute), and Phase 1.7 agent-end-to-end.
