Module runner 

Structs

MilestoneEvaluationContext

RuntimeOptions

Configuration for a RuntimeRunner (aligned with Node/Python RuntimeOptions).

RuntimeRunner

Orchestrates the agentic turn loop via the runtime kernel + session event log.

TurnMetrics

P0-C tool-gating telemetry: per-LLM-turn metrics, delivered to RuntimeOptions::on_turn_metrics. Pure observation — no behavior change. tools_exposed vs tools_called quantifies over-exposure; consecutive equal active_skill values measure skill dwell D; the cache split gives the prompt-cache hit baseline. Mirrors the node SDK TurnMetrics.

Enums

MilestonePolicy

Controls what the runner does when the state machine returns EvaluateMilestone — i.e., the LLM finished a turn but a milestone phase has not yet been evaluated.

Functions

collect_text

Type Aliases

MilestoneEvaluationHandler

OnTurnMetricsHandler

Sink for per-turn TurnMetrics. Synchronous, infallible — it must never affect the run.
