Pagefind Evaluation (Wave 2.9)
Decision: Ship VitePress local search (MiniSearch) for Wave 1–2.
When to adopt Pagefind: if Engineering Core + ADR catalog exceed ~150 pages and relevance regresses. Pagefind adds a static WASM index at build time with no Algolia dependency.
Optional Wave 3: Algolia DocSearch if the project joins the DocSearch program.
