- Trade blocks: none on a battery with no room, no sale at a negative price or while the emptiest battery is at arbitrage's floor, nothing when a level is unknown. A give after a charge may use what the charge put in. - The refusal line names the real reason: prices not published vs gap. - The plan's peak line uses the guard's ceiling (this month's peak once above the cap), as the peak card does. - House below zero: 0 W inside the idle band, no figure beyond it. - Price bars are "Low price" / "High price": the add-on trades in one hour. - Control toggle: one request in flight at a time. - test_home: the new cases; the house-sign mutation now goes red.
