Match each architectural concept to its defining scope in agent runtime execution.

Arrange the stages of a phase-level execution cycle in chronological order from stage initiation to boundary transition.

Analyze why Design A degrades agent problem-solving performance compared to Design B, and identify what internal condition Design B preserves during a stage of work to prevent this degradation.

What occurs if pre-commit checks fail during an attempted phase-level state transition?

A phase-level state architecture decomposes agent execution into fine-grained, isolated micro-actions rather than coarse stages of work.

What three operational tasks are performed by the entry hook (in_hook) upon entering a phase-level state?

Explain the responsibilities and operational purpose of the exit hook (out_hook) when departing a phase-level state.

The primary execution space where an agent conducts open-ended reasoning, invokes tools, and iterates on phase goals is the ___.
