Kerning pair references missing glyph

Definition

A kerning pair references a glyph that doesn't exist in the project. The pair is dead weight — either draw the missing glyph or remove the pair from the spacing tab.

How Patens surfaces this

The Patens audit module checks for pair-missing-glyph 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 is detection-only — there's no automatic fix because the correction is design-dependent (it requires a judgment call about the glyph's intended shape or the font's intended behaviour). The audit message links to the specific glyph or field that needs attention.

Run this check yourself

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

npx patens audit your-project.font.json
