Map Pack Entries in Practice
The cost of conflicting category choices is not a penalty; it is being quietly ranked below someone tidier. Give one person the logins and one document the truth; ambiguity is what causes drift.
Record the canonical version of the core contact record somewhere the owner can find it. Verified records are one of the few local levers that still work without a budget, assuming the basics are already in place. Beyond that most damage here is self-inflicted: an abandoned profile introduced during a rebrand or a move. What follows from this is that data flows outward from aggregators, therefore an error at the source reappears in places nobody submitted to.
