The resources/database/drizzle SQL files and meta snapshots are v1-era CherryClaw agents-db migrations with no runtime consumer — the active v2 migrations live in migrations/sqlite-drizzle and are loaded from app.database.migrations. Delete the directory and clean up the now-dangling references: three source comments in AgentsDbMappings.ts that cited the deleted SQL files as the v1 column-type source (the epoch-ms notes are kept inline), and a stale doc row in cherryclaw/scheduler.md pointing to a migration file that no longer exists.
