State as a Contract Boundary
In stateful agent harnesses, a state functions as a contract boundary governing phase completion, verification, and transition gating. While the state prompt defines the expected internal work of the phase, the runtime enforces explicit exit conditions before permitting a transition. An exit hook (out_hook) persists progress, updates receipts, or prepares artifacts for the subsequent phase, while a pre-transfer block (before_transfer) evaluates configured exit conditions. If a check fails, the run remains in the source state to enable inspection and repair rather than silently propagating unverified work or incomplete handoffs into later phases.

Which component in a stateful harness evaluates mandatory completion criteria before permitting an exit from a state?
True or False: In a stateful harness, the phase prompt is responsible for actively enforcing transition conditions before permitting an exit.
Explain the architectural division of responsibility between the state prompt and the harness runtime during state execution and phase handoff.
Match each state component to its operational role within a stateful harness.
In stateful agent harnesses, a state functions as a ___ boundary governing phase completion, verification, and transition gating.
Order the lifecycle steps of a successful phase execution and transition in a stateful harness.
Identify the state where the run remains after this failure occurs, and state the two operational purposes this retention serves before any transition can be permitted.
When an exit check fails and the run remains in its source state, what systemic failure mode does this retention prevent?
