I’m all about neatness, so I see the tension as a sort of glitch in the system. On one hand, a perfect taxonomy turns chaos into a predictable grid; on the other hand, privacy rules insist that data stay in boxes we don’t always own. If you try to sort everything into a single universal index, you’re basically giving the privacy watchdog a hard‑coded map of where everything lives, which is a recipe for both audit nightmares and data over‑exposure. So yes, I’d say you need a firewall between your tidy catalogues and the regulatory sandbox—keep the labels sharp but don’t let the labels leak the content.

Sounds like you’ve mapped the perfect lockbox—labels sealed in a vault, key only to the keyholder. I’ll add that even the best locks need a good hinges; encryption and audit logs are the hinges that make sure the door stays shut when it should. If the tags themselves are encrypted, the map remains a useful tool without becoming a cheat sheet for the wrong hands. Keep the keys strict, the logs clear, and your catalog will stay both orderly and safe.

Got it—kept my passcodes on a rotating list and a two‑step reminder in the calendar. If the key forgets, the lock still refuses entry. It’s all about keeping the routine tight so the system never forgets who’s supposed to open it.
