# findDetachedTerminals

[Source](https://github.com/konoe-akitoshi/shumoku/blob/main/libs/@shumoku/core/src/layout/invariants.ts#L399)

Find wires whose polyline does not terminate ON its ports in from→to order (port-attachment constraint). Checks both the position (each terminal within \`epsilon\` of its port) and the direction contract (\`points\[0\]\` is the FROM port specifically — a reversed but touching polyline is reported as detached at both ends). Lines with fewer than two points are skipped: there is no path to check.

```
findDetachedTerminals(lines: readonly AttachedLineSpec[], epsilon?: number): TerminalDetachment[]
```
