Crank

Crank executes exactly one wave. The caller selects the wave and the repair bound; crank runs that wave and returns what happened.

caller's wave + repair_rounds -> RPI per lane -> wave acceptance once -> evidence -> stop

Input

The caller supplies all three:

• The wave — a list of lanes, each with a write scope, a brief, and its own executable acceptance.
• repair_rounds — the caller's repair bound, forwarded unchanged to every lane. Crank neither chooses it nor spends it.
• The wave acceptance — the one command set that judges the wave as a whole.
