Player use
Dead layers and liminal seams preserve routes, wounds, signs, and returns. The command surface should stay direct, readable, and useful in a MUD client.
System
Liminal Persistence
The city holds routes, scars, journals, and dead-state crossings. Some places only make sense after death opens the layer below.
World use
This system connects to Seattle routes, live records, discovery, and the player journal so actions leave usable traces.
