Tiny contour
Auto-fixAudit code: tiny-contour
Definition
A contour smaller than 8fu in both dimensions — usually a stray artefact from a boolean op or imported SVG.
How Patens surfaces this
The Patens audit module checks for tiny-contour 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 tiny-contour firing on real
glyphs, or check your own work from the CLI:

Primary literature where this rule is established or explained. Drawn from the open-licensed corpus — browse the full 42-source canonical library or read the research artifact.
The canonical authority for this rule sits in the in-copyright craft canon (Tracy, Smeijers, Noordzij, Cheng) which requires licensing before body-text ingestion. We cite these by bibliographic reference only — see the library for the full 42-source canon, or the research artifact Section 2 for the family-specific citation matrix. Q3 2026 work expands the corpus once publisher relations land.
