Session 53 closeout (HMW-mode ON, 'làm hết' full close). Code already shipped in 44b9e54 (Mig 47, Run #260) + dbf6648 (C+D, Run #261), both prod-verified.

- Doc-drift E (H1 top-5): ef-core skill 43->47, agents/README roster 10->11 + plugin nac, CLAUDE.md root 45->47 mig + 186->203 test, docs/CLAUDE.md 56->57 gotcha + 91->92 ERD.
- adap-report: database-agent executed-file -> verified-runtime (spawn-test caught Mig 46-unapplied-local).
- session log 2026-06-08-S53 + 4 agent diaries (S53 work).
- Memory: +project_database_agent_verified_local_drift (user-memory, outside repo).
