K-404
K-404 is an environmental NPC: an old lost-and-found terminal trapped in the instruction “return lost property.”
Function
It must not be only a lore terminal. Its trust state gates the quiet return ending and static/silence code access.
First encounter
D-17 front desk terminal on first station entry.
Miss / recruit logic
The encounter is not missable if D-17 is visited. The trust route is missable.
K-404 is not a follower; it can become a facility ally or quiet archive holder.
Mechanical impact
- Counters:
k404_trust,lost_property_protocol,static_code_access - Unlocks: static/silence code, quiet return ending, D-17 silent archive cabinet state
- Lens requirement: K-404 trust gates the quiet return ending.
