/**
 * Session 64 Order 1 — date-targeted settlement + terminal states.
 *
 * The bug: a lookup miss did `pending += 1` with no terminal state, so a row
 * that could NEVER settle (DNP, or the rolling window passed the game) was
 * indistinguishable from one settling tomorrow. These lock the distinctions.
