Definition
Scope growth by accretion, where each extension of an automated system is too small to trigger review and no single step is the one that widened the delegation. The ratchet turns one way only: successful operation is read as licence to extend.
It matters because the end state bears no relation to what was originally justified and no single decision can be pointed at. The countermeasure is to make each widening an expansion decision, which is also what keeps authority drift from being invisible.
