swung0x48 9a494b6f01 [docs] (P7): magma-b3 - the wire arm's frame-serial floor was raised on a fence it had not waited ...

Mechanism with file:line and the submission structure measured rather than assumed, the
confirmation tallies (zero unforced, which refutes the silent-draw-drop hypothesis the
investigation ranked first, and which the judge refuted independently on the prefix-tear
forensics), the provable floor, the fence-backed second term in WriteWireBuffer, the red-once in
three forms (a deterministic counter 26/26/0 -> 0/0/0, a two-process lane case, and forced OpenRA
retraces), the gate numbers, and the device acceptance with three predictions H1 must satisfy.

Records honestly: an earlier draft of this note blamed TryDrainFrameTransients' every-8th-drain
frame boundary, which this package's own probe refutes (one successful drain in the whole replay,
zero frame-boundary ones, all 33 serial bumps from Present); the GPU-drag knob the judge suggested
was not built, with the reason; the aggregate-wait secondary fix is left to a separate package
with the lane evidence that nothing in this tree's coverage regressed without it; and M1's
"present fires once" observation does not hold for OpenRA, whose pbuffer replay presents every
frame.
