STAT table missing (familyAxes unset)

Audit code: stat-missing

Definition

Variable font has axes but no familyAxes set — Patens needs the family-position to generate the STAT (Style Attributes) table at export time. Without STAT, OS font menus may display style names incorrectly (Windows in particular). Set the family-position on the Family tab.

How Patens surfaces this

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

npx patens audit your-project.font.json

    Microsoft Typography · 1997 · Microsoft Corporation· § STAT — Style Attributes Table

    STAT records the canonical axis-value names, default values, and italic-linkage needed for proper variable-font display in OS font-pickers. Without STAT, Windows in particular can display style names incorrectly (e.g. "Regular Bold Italic" instead of "Bold Italic").

    STAT is a per-axis label registry that the OS uses to compose instance names; the practitioner guidance covers why it matters and what to put in it.
