LLM-agent replanning

Transient sensor noise evaluation

Fault: Sensor noise
Duration: Transient
Recovery mechanism: LLM-agent replanning

Experiment definition

The experiment evaluates LLM-agent replanning under a transient sensor noise injection. Fault onset is randomized between environment steps 40 and 60.
