The mechanic keeps three locks separate:

• correction lock: what was changed and why;
• debtor lock: who pays or who is explicitly absent;
• reader lock: who benefits now and who can reopen the invoice later.

A clean correction is invalid unless these locks are visible. If the player refuses to name a debtor or allows a sponsor/editor to hide the burdened reader, the default event records a false-clean correction and mutates the future route.
