What does the Staff Only clue say?
The official listing says that prisoners are taken behind the STAFF ONLY door after lights out and “don't come back the same.” That is a real story clue, not proof of a secret code, guaranteed ending or one specific door-opening method.
How to investigate it without wasting a run
- Record the current title/version marker and the visible time or night state.
- Watch the prison during the lights-out transition and note any objective, sound cue or guard movement shown by the live game.
- Keep tools, cash, suspicion and team size in separate notes; do not infer a key from a nearby item without testing it.
- Repeat the observation in a second run before calling a trigger guaranteed.
- Capture the exact result card, route or reward if the door interaction succeeds.
Until a repeatable run exposes the interaction, EarlyWiki will not publish a “secret key,” “free ending” or Staff Only shortcut. Use the main walkthrough for the confirmed day/night loop and the tools guide for the equipment evidence.
