Module pending_reason 

Why a pending ledger row is still pending.

The ledger records only that a row is waiting, never what for: the answer changes the moment the student links a number, and a stored copy would be a cache to keep true. Every surface that names the blocker derives it here, from the same facts preconditions::pending_moves decides the row’s next state from.
