Once a system enters a chokepoint regime, control, taxation, security, and crisis management all become disproportionately concentrated at a few sites.
This often produces both high leverage and high fragility.
A chokepoint regime is not just a map containing one narrow pass or one important harbor. The term applies only when closure or control of that site reorganizes outcomes across the wider network instead of causing a merely local inconvenience.
If closure of one gateway would reorder pricing, security, route choice, or political leverage across a much larger field, the system is operating under a chokepoint regime rather than merely containing an isolated chokepoint.
Military concentration, customs clustering, and repeated crisis attention around the same few crossings are the clearest signs that the wider system is regime-shaped by those gateways.
A strait, mountain pass, or estuary gate can produce a chokepoint regime when most trade, taxation, and reinforcement options for the larger region are forced to pass through that same narrow interface.
Once that condition exists, the surrounding geography starts inheriting the priorities of the gateway. Security, bargaining, and investment cluster there because the wider system cannot behave normally without it.
The regime is visible precisely because the whole map starts orbiting one narrow interface.

Detail pages now expose the branch and scale of their surrounding graph before showing raw prerequisite and relation shelves, so continuation can stay taxonomy-led instead of adjacency-led.

Explain how topology, region graphs, corridors, map abstraction, and scale determine movement and leverage.
Start in Spatial, reduce the map into region graph and corridor logic, test topology under disruption, then return through a spatial design guide.
Glossary entries define Spcent's shared vocabulary. They are conceptual anchors designed to stabilize how an abstraction is used across pages and modules.

A glossary term should lock down what a phrase means so later reading is not burdened by ambiguity.
