Back to Search-quality baseline: v1.2.0 candidate `search.db`

The four queries that did not yield a top-1 match. Each is informative.

Query | First-relevant rank | Top-1 returned | Note
--- | --- | --- | ---
`SwiftUI View` | not in top 10 | `apple-docs://clockkit/swiftui-templates` | Two-word query. `View` token bound to `swiftui-templates` URI dominates over the canonical `apple-docs://swiftui/view`. Probable cause: the query text `SwiftUI View` ranks pages with both tokens highly, and clockkit/swiftui-templates contains both, while swiftui/view contains them less prominently in the indexed body. Realistic regression class for users typing two-word lookups for framework-rooted concepts.
`Combine Publisher` | 2 | `apple-docs://combine` | Top-1 is the framework root; the canonical `combine/publisher` page is at rank 2. Defensible result for a two-word query naming both the framework and the protocol; an LLM consumer reading top-2 sees what it needs.
`CoreData` | 3 | `apple-docs://foundation/cocoaerror/code/coredata` | Top-1 is the `CocoaError.Code.coreData` enum case, not the Core Data framework root. Probable cause: `framework_aliases` table maps `coredata` → CoreData but the framework root isn't winning the BM25F tie. The two preceding hits are deep API pages that contain the literal token `coredata`.
`MapKit` | 2 | `apple-docs://mapkitjs/mapkit` | Top-1 is the JavaScript variant (`mapkitjs`) instead of the native `mapkit` framework. Probable cause: `mapkitjs/mapkit` contains the token in both framework and path positions; native `mapkit` only in the framework position. Source-authority weights should bias toward native; they don't here.

None of these is a regression vs the brew baseline (the paired pilot run on 2026-05-20 had the same outcomes); they are pre-existing ranking artefacts of the current BM25F + RRF configuration. Each is a candidate for a per-class follow-up evaluation per `docs/design/search-quality-eval.md` §14.2 (specifically class B framework-root for `SwiftUI View`, `Combine Publisher`, `MapKit`; class C acronym/synonym for `CoreData`).
