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.
