Evidence boundary
The corrected v0.3.1 planning metric reuses previously opened v0.2 cases and is not a fresh sealed confirmation.
Declared limitationsTrained and evaluated on PC-Gym 0.1.8 four_tank trajectories, not a physical plant.The package models the declared four-level state and two pump inputs only.Pump schedules are advisory. A plant safety system must retain execution authority.
