session-mode

Resolves project-level single-session vs multi-session execution and prints role-specific identity prompts. Once project.session_mode is present in .agentic-rounds/state.yaml, do not ask again per round.

Workflow

1. Read .agentic-rounds/state.yaml and the round handoff.
2. If project.session_mode.mode is already set, treat it as fact and skip the recommendation/choice step.

3. If no project-level mode exists, generate a recommendation:

   arcgentic session-mode recommend \
     --round <round-id> \
     --handoff <handoff-path>

4. Print recommendation, confidence, reasons, suggested role identities, and override instructions before asking the user to choose.

5. Print only the identity handoff prompt needed for the next role:

   arcgentic session-mode prompt \
     --round <round-id> \
     --handoff <handoff-path> \
     --mode multi-session \
     --role developer

   V1 valid roles: developer, auditor, closeout.

6. For V2 Codex-native orchestration, generate the fixed-role host plan instead of per-round role prompts:

   arcgentic v2-session-plan \
     --state .agentic-rounds/state.yaml \
     --host codex

   V2 session roles are fixed to Orchestrator, Planner, Developer, and Auditor. close-round is an orchestrator-owned command, not a session role.

Boundaries

• Do not enter developer work before the mode gate is resolved.
• Do not re-ask the user when project-level mode is already stored.
• Do not claim single-session auto-audit when dispatch transport is unavailable.
• In V1, developer, auditor, and closeout identity prompts must remain separate.
• In V2, keep exactly four fixed role sessions and never create round-numbered role threads.
