Near-collinear points

Definition

A point sits within 1fu of the line between its neighbours — a vestigial node, safe to remove.

How Patens surfaces this

The Patens audit module checks for near-collinear-points across five teaching surfaces: the edit-panel inline issue list, the project-wide audit page, the release pre-flight check, the family hub, and the home-page project tile. Every surface shows the same plain-English explanation and links back to this page. This rule has a one-click Fix button in the editor — the audit module both detects the issue and applies a deterministic correction with a labelled snapshot, so the ⌘Z path back is preserved.

Run this check yourself

Patens runs every audit rule live as you draw — including this one. The editor (in private alpha) shows near-collinear-points firing on real glyphs, or check your own work from the CLI:
