Need to double-check this, but I don't think we should expose (or at least always expose) traces/tick-tock at the sequence level if possible. There should maybe be a more approachable vernacular that tells users what properties they'll get:
traces refinement: 'behaviours', or 'safety'
tick-tock refinement: 'behaviours and deadlocks', or 'safety and liveness' (tick-tock deals with divergence, right?)
