rolepod-dblab

Data-layer safety + truth verifier for AI agents — MCP server with 5 rolepod_db_* tools + 5 shipped skills (db-introspect, db-query, db-explain, db-migrate-verify, db-write). Works standalone OR with the `rolepod` parent plugin: when the marker file `<git-root>/.rolepod/parent-active` is present (written by the parent's SessionStart hook), evidence routes to `<git-root>/.rolepod/evidence/` with a `manifest.json` per Extension Protocol v1, so the parent's check-work skill can aggregate DB state as a first-class evidence type. Not a generic SQL client — the value is safe mutation (preview→confirm→commit/rollback), schema-drift detection, and DB state as PASS/FAIL evidence.
