Gate: corruption robustness (LavaGapS7)

Project: Trust-Calibrated RL · Environment: MiniGrid-LavaGapS7-v0 · Schema: research.v1 · Published: 2026-08-21

Research question

How does PPO performance on LavaGapS7 degrade under observation corruption, and does corruption-trained robustness transfer to held-out corruption families?

Training and evaluation metrics are recorded separately; a stochastic training rollout is never presented as a controlled evaluation. Trust calibration and protective actions (ACT/VERIFY/DEFER/ABSTAIN) are research milestones — not implemented, and no values for them are shown anywhere.
