// This file holds the production adapters that satisfy the small interfaces in
// deps.go over the real db, browse and core-go layers. Tests do not use these;
// they inject their own fakes. Each adapter is a zero-value struct with a
// compile-time interface assertion so a signature drift in a committed package
// breaks the build here rather than at Phase-3 wiring time.

// DBAdapter satisfies RepoStore over the request-scoped db.Store. It holds no
// connection: every method builds a Store from the *sql.DB the core-go database
// middleware installed in ctx (db.FromContext), so one value serves all
// requests and leaks nothing.
