Module equivalence 

2026-09-26: Whether two boxes count as one box for Speed-class numbers: same GPU name and driver major, clock ceiling and memory within the class’s spreads, no thermal throttle reason asserted, and hottest chassis zones within its delta.

Owner: bench hardware. Invariants:

• equivalent returns Ok only when every field but postcheck_valid is reported on both sides; a field one side lacks is Mismatch::Undecidable.

gate::agreement applies equivalent to the Speed records of different signers, and that is the verdict. met bench certify calls it only to report whether its nodes look alike (remote/schedule.rs speed_mode runs the Speed class on one node either way).
