Module plan 

AI Plan Definition

A Plan represents a sequence of steps that an agent intends to execute to complete a task.

Versioning

Plans are versioned monotonically. As the agent learns more or encounters obstacles, it may update the plan. Each update creates a new Plan object with plan_version = previous + 1.

Steps

Each step has an intent (what to do) and a status (pending/in_progress/done). Steps can also define expected inputs/outputs for better chain-of-thought tracking.

Structs

Plan

Plan object for step decomposition. New versions are created via new_next with monotonic versioning.

PlanStep

Enums
