Typographic essentials coverage incomplete
Audit code: coverage-typo-essentials
Definition
The typographic essentials subset is incomplete — basic punctuation and spacing characters that every font needs to feel finished (period, comma, hyphen, space, colon, semicolon, quotes). Some text will render with system-font fallbacks for the missing glyphs.
How Patens surfaces this
The Patens audit module checks for coverage-typo-essentials 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 coverage-typo-essentials firing on real
glyphs, or check your own work from the CLI:

The "typographic essentials" subset includes punctuation, spaces, and ASCII; missing any of these breaks basic text rendering.
