sprint-retrospective

Run the iteration retrospective as a rite — consult each persona that ran, one at a time and in isolation, on what should change in how we work, each reasoning from its own artifacts rather than from memory. Use when the drain reports its entry snapshot exhausted, or when the owner types it against an iteration that was worked by hand. Produces a proposal he rules on at planning, never an Issue and never a change. It takes an optional iteration title as its argument, typed after its name; without one it uses the active iteration.
