Decision

#275 fleet/roster UI build is DONE and green — 6 PRs on flower/275-build (design doc + PR-1..6), full suite 1381 pass / 3 skip / 0 fail, pint clean. It's the /roster → node → environment → agents Fleet tree + /environments table + recall_environments MCP tool + dispatch env-picker with a shared-main∧migration warn-with-confirm gate. Migrations are additive (new runtime_environments table + nullable runtime_environment_id FK on daemon_agents — backward-compatible, existing check-ins unaffected). Design was already blessed via the design loop + your decisions #75/#76. Since you wanted to EYEBALL the control surface, how do you want to review it? (Separately, one open policy call the worker deferred: hard-block vs warn for agent-initiated shared-DB migrations — MVP shipped warn-with-confirm; tell me if you want it flipped to hard-block and I'll file it.)
