2026-09-26: HardwareStateReport: the two captures, the delta and both
verdicts, as one value that travels with the run into its gate record
(GateRecord::hardware_state, .benchmarks/<id>/<date>-<sha>.json).
Owner: bench hardware.
Invariants: none beyond the types. HardwareStateReport::close sets after,
delta and postcheck together.
