The second metal foot stopped behind Yara's wall.
The first one carried weight.
Its pressure bowed the black threshold under her bare heel. Water crept over the rim of the shallow pan and ran toward the completed mark. Yara caught the pan with her left hand before the next vibration could empty it.
"Camera high," she said. "The floor throws loose things first."
Eri gave her slack. Yara wedged the flat camera between the hanging chain and a wall seam above her head. The view kept her whole floor, the water pan, and the completed threshold inside one frame.
Yara paced the floor in two long steps and one short one. Her outstretched arms nearly reached both side walls. No door, cot, food sleeve, or second water vessel occupied the room.
A third impact landed to her left.
Chalk dust jumped from the wall and settled in a curved line. Yara rubbed one mark into the floor with her boot toe.
The fourth landed behind the water wall. The pan shivered in her hand without spilling.
