The Shell Universe › Architecture
Seams
The hidden joints in a system — where one threshold ends and another begins.
Seams are the structural joints of the Shell's architecture: the transitions between rooms, protocols, people, and jurisdictions. They are where systems are most vulnerable and most honest. A seam, properly read, reveals the true logic of a structure.
Why it matters
Seams are how the novel shows that every system has edges — and that edges are where the real decisions happen.

The Shell is built around this architecture. The first two chapters are free — they introduce the world, the signal logic, and the first threshold.
