Throughput is the concept that prevents route maps from being mistaken for functioning systems. A corridor may connect two places perfectly well in principle while still failing under the volume demanded by campaign supply, urban provisioning, or mass migration.
It also explains why bottlenecks appear in surprising places. Sometimes the weak point is not the road itself but the customs gate, repair yard, granary mouth, or unloading labor that caps the wider flow. Throughput forces you to look at the whole chain.
Throughput is not identical to width, speed, or nominal capacity. A broad road with poor unloading discipline may have worse throughput than a narrower but better-buffered corridor. A fast signal network may still have low institutional throughput if decisions cannot be processed or authorized in time. The term always implies sustained flow under real operating conditions, not optimistic maximums.
Queues, waiting time, backlog, and forced priority choices are usually the clearest signs that throughput is the real problem. If goods, people, or instructions keep arriving but cannot clear the next stage smoothly, the system is already telling you where its limit sits.
Continuation Map
Use this node as a deliberate step, not a terminal page.
Read what should come before it, what relation role matters next, and where this page should hand you off after the local graph is clear.
Before this node
2 prerequisites to read first
Start with Corridor and then return here once the surrounding concept stack is clear.

3 typed paths across 2 continuation roles
These entries clarify the footing underneath the current node before you move outward again. Start with Route Hierarchy when you want the clearest next role.

Open Spatial
Many glossary abstractions become richer when viewed inside the spatial module.
Continue from this node by program branch and operating scale.
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.

Flow and Logistics
2 entries
Explain how resources, goods, labor, information, and force circulate, stall, buffer, and break.
Start from the resource-flow loop, trace storage and throughput models, compare one logistics study, then run a flow audit worksheet.
Use operationalizing relations when you want the current abstraction rendered as a cleaner model, loop, or structural device.

How to read a glossary entry
Glossary entries define Spcent's shared vocabulary. They are conceptual anchors designed to stabilize how an abstraction is used across pages and modules.

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

When you know the concept but not yet the best framework or model, start here and then move outward through related nodes.

Glossary should connect outward
A useful definition points toward the frameworks, models, and studies that actually use the term in context.
