The Divide systems
A short guide to the working language of The Divide. These are descriptions of the fictional setting, not instructions for operating real equipment.
Heat reserve and heat delivery
A reserve measures energy available to the system. Delivery depends on routes, flow and demand. A colony total cannot describe the temperature of every household.
The Drawdown
The agricultural extension at Olympus Prime draws heat from the shared network. Growing food and heating homes are connected demands.
The Bottleneck
The Bottleneck constrains circulation toward Renticuluous Alpha’s far districts. Its significance is introduced with the three habitats.
Isolation and stop rules
The Valles crews use defined conditions for stopping, checking and restarting work. Anika and Paul Evans must distinguish a plausible plan from evidence that a system is safe to use.
Records and responsibility
Drawings, logs and signatures preserve decisions. The novel asks what it means to take responsibility for the gap between a record and the physical system it describes.

Reading a system at several scales
The opening household diagram names air, water, heat, food and power. The plant view adds production and distribution; the habitat view asks whether those services reach the people who need them. Moving between these scales is a useful way to follow the technical language.
The diagrams in the story also carry human assumptions. A name beside a loop can express trust as well as responsibility. Everyday life explores this connection to school and family.
