The brief told the agent to ask for a phase change and never carried the
asking. The agent asked in prose, no code represented the request, and the
session idled until its lease expired. That is what failed run 3.
F21. The agent asks with .orchestra/phase-request.json, and seals
research.json or plan.json where the phase it is leaving produces one. At a
verified turn boundary the worker checks the phase belief, the transition and
the artifact, then calls the coordinator with its lease epoch and a derived
operation id. AdvanceWorkPhase is unchanged, so a request cannot reach a move
the operator surface could not also make. Redelivery is idempotent.
F22. A session now records the phase it was launched to run. One that no
longer matches its task rotates with reason phase_changed, whether this worker
asked for the change or an operator made it.
F20. CLIAdapter.prompt sent handoff and rotation prompts without confirming
them, which is the failure F20 exists to catch. Fixed at the shared call site.
F23 needed no change. Issue comments already become decisions with no
submission, through Reconciler.Reconcile at PreLease and at every turn
boundary. The earlier finding searched internal/operations alone and was
wrong. Tests now cover the boundary it turns on.
