Treat access as evidence
In a station mystery, an access card can identify permissions, connect a person to an area, or simply open a route. Those meanings should not be collapsed into one assumption.
Card checklist
- Visible owner, department, or clearance label
- Place where the card was found
- Doors or terminals that accept it
- Whether the access state survives a loop
- Records that explain why the holder needed that access
Finding a card in a room does not prove its owner left it there. Likewise, opening a restricted door establishes permission, not guilt or motive.
Official material supports access-control and investigation themes, but does not publish a complete card list. Names and locations should be added only from direct, versioned observation.
