Full-text search behind a swappable interface (ADR 0010).
- prisma: `page_content_cache.search_vector tsvector` (Unsupported column);
migration adds it plus a GIN index (raw SQL — the index is a production
perf optimization; correctness holds without it, so schema-pushed test DBs
work unchanged).
- shared: `normalizeForSearch` (NFKD + strip diacritics + lowercase) folds
both the indexed text and the query, so 'Baume' finds 'Bäume' without the
Postgres `unaccent` extension; search query schema + result view + highlight
sentinels.
- api search module:
- abstract `SearchProvider` (DI token: indexPage / removePage / search /
reindexAll) so an external engine can replace the binding — a fake proves
the seam in a test.
- `PostgresSearchProvider`: weighted vector (title A, labels B, body C),
`websearch_to_tsquery`, `ts_headline` snippets, results filtered to the
ponds the user may read; `GET /search?q=&pondId=&labels=`.
- `search:reindex` CLI (rebuilds from the content cache, idempotent).
- reindex hooks: page create/rename (title) and label assign/unassign/
rename/delete (labels are weight-B).
- collab: the persistence hook maintains `search_vector` in the same
transaction as the content cache (same weighting, normalized).
- tests: shared normalize/schema; api db (title ranks above body, highlight,
diacritic-insensitive match, permission filter, idempotent reindex) and the
fake-provider DI test; collab persistence already covers the write path.
