B's power reading shows -95 to -118 W at idle (standby draw), so the |reading| < 100 W refusal band never held a refusing B: never at N=2, and since SAFETY-94's shared rule not at N=1 either (review F1). Each unit now learns its idle reading (app/idle.py): only while control runs, the unit is not refused/stale/tripped and its command has stayed within 50 W for 120 s; first value a 120 s mean, then a 30 min follow; samples beyond 250 W dropped, value clamped to 250 W; saved per unit and restored. The shared refusal evidence, compute()'s N=1 engage and end, the unit refusal ends, the stale-path refusal and SAFETY-42's "parked" test are centred on it. Until learned it is 0 W, the rule as it was. Refusing B caught at N=1 28/28/65 s and N=2 24/24/60 s (1/2/5 s meters), before never; refusing A unchanged. Healthy B with its offset, SAFETY-94's scenarios, 96 runs: 0 stale, 0 refused. Live replay: 0.
