Master contour count mismatch

Audit code: master-contour-count

Definition

The number of contours differs across masters. VF interpolation requires identical contour count and order in every master.

How Patens surfaces this

The Patens audit module checks for master-contour-count 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 master-contour-count firing on real glyphs, or check your own work from the CLI:

npx patens audit your-project.font.json
