Defined in:
lib/fontisan/audit/checks/opentype_conformance_check.rb

Overview

Foundational cross-table OpenType spec conformance checks. Per-table rules live in their own check modules (HeadCheck, HheaCheck, Os2Check, NameTableCheck, PostCheck, KernCheck) to keep each concern MECE.

This check owns the rules that span multiple tables:

- Required tables for each sfnt flavor (TTF vs CFF vs variable)
- head.indexToLocFormat consistency with loca table byte size
- hhea.numberOfHMetrics must be ≤ maxp.numGlyphs
