Test	What it does	Result
test_layer_apart	No explain() row in this layer is an epsilon, and the finite-key length for the same family comes from q.security.keylength, in bits.	✅ pass
test_rates_shipped	q.rates is in __all__ and registers exactly cow-vacuum, pairing and rrdps, each catalogued.	✅ pass
test_units_stated	Each family names its own per-shot unit on every rate: a round for pairing, a pulse for RRDPS, and a pulse plus its two-pulse sequence for COW'.	✅ pass
test_working_shown	Every rate carries the engine's intermediate quantities under the engine's own names, each row labelled pinned or derived.	✅ pass
