Result of the timeout path's expiry statement. entry is the row that
moved pending → expired (with resolver_payload set when the row
delivers a collection), or null when no pending row carried the key.
priorStatus names the row's status before the statement when a row
exists, so the caller can tell "a resolve won" from "no row".
