NOOA post-training readiness

Goal

Define and close the remaining gaps required to use NOOA agents for Gym-based post-training.

This work builds on the object-oriented agent integration in #2096 and the CLU evaluations for NOOA agents in #3453.

Scope

The initial scope is an RFC describing the target post-training architecture, required rollout contracts, integration boundaries, validation plan, and staged delivery milestones.

Features

• #3459

Success criteria

• The RFC defines how NOOA rollouts become training-ready data.
• Required model, trajectory, reward, token, and failure contracts are explicit.
• Dependencies on the existing NOOA integration and CLU evaluation work are identified.
• Reviewers can approve a concrete implementation plan with measurable readiness gates.
