05 — Migrate turn and 分神化身 lifecycle

[XMethues]

Parent

#1

What to build

Migrate turn and subagent lifecycle activity to the normalized intake. Treat session end as the authoritative turn boundary and show subagent work without awarding cultivation twice.

Acceptance criteria

• The documented pre-LLM hook starts a turn and the documented session-end hook is its authoritative end.
• A post-LLM hook is not treated as the authoritative end of the turn.
• Normal and interrupted session endings close the matching turn and are neutral in reward/penalty terms.
• Subagent start and stop hooks track each subagent by identity and surface active work as 分神化身.
• Delegation cultivation reward is applied exactly once through the parent delegation tool result, not again through subagent lifecycle events.
• Display priority places direct tool activity above 分神化身, then recent outcome, then 推演, then 入定; 候旨 remains highest priority.
• Parallel subagents and direct tools settle independently and cannot incorrectly force the aggregate state to idle.
• Hook adapters tolerate additional Hermes keyword arguments.
• Real-HTTP integration tests and fake hook-context tests cover normal, interrupted, parallel, and out-of-order lifecycles.
