Architecture

Quantum-QEC uses a control loop with action validation, composite noise, syndrome measurement, reward decomposition, and deterministic grading.

Pipeline

1. Reset task config and seed.
2. Agent sends QECAction.
3. Environment sanitizes action.
4. Noise model injects stochastic + drift-coupled errors.
5. Surface code computes syndrome.
6. Reward module returns shaped step reward.
7. Grader scores terminal episode in [0,1].
