/**
 * v1 EAV Database Layer — REMOVED in v2
 *
 * The old `records` table has been removed (spec section 12.3).
 * All v1 API routes that used this module will be replaced in Phase 2+.
 *
 * This stub exists so the build compiles. It returns empty results at runtime.
 * New code should use Drizzle directly via `@project-e/db`.
