Narrow Point

Bottleneck surface

The Narrow Point is the structural bottleneck through which energy, decisions, and constraints must pass. It is the lowest governing constraint in the system.

Identifies

• the single unavoidable constraint
• the point of maximum tension
• the structural bottleneck
• the location of collapse expression

Does not

• interpret motives
• describe behaviour
• assign responsibility

Signals

where collapse will express · where energy localises · where reconfiguration must occur

Pre‑Collapse Narrow Point

Before collapse, the Narrow Point expresses as inward curvature and tightening. There is no throat, no compression, and no axial segment. It is the approach to inevitability, not the collapse itself.
