Agents develop on branches and submit PRs, with **automatic merge once both required CI checks pass** in the current solo-maintainer setup. [`CODEOWNERS`](.github/CODEOWNERS) records future maintainers, but approval is not currently mandatory. CI runs Node.js 22/24 and PostgreSQL/pgvector checks. Never store bot tokens in this repository.
+Agents act through the `memo-labs-automation` GitHub App (`memo-labs-automation[bot]`); the former `drop-agent-bot` account was retired on 2026-10-14. Agents develop on branches and submit PRs.
