<MODULE_CONTRACT>
<purpose>
  RFC-0263: parity fixture — captures buildPage's hideSectionNumber injection
  behavior for hero-role blocks (Europa, Phobos) and confirms a non-hero block
  never receives the prop. Written against the roleByCosmicName-driven
  implementation (which replaced the UNNUMBERED_HERO_PLANETS literal set) to
  guard byte-identical output going forward.
</purpose>
<non-goals>
  <item>Not a contract source of truth — the module under test owns the authoritative behavior; fixtures are minimal scaffolding only.</item>
</non-goals>
</MODULE_CONTRACT>
<CHANGE_SUMMARY>
  <item>RFC-1311: Compass header sweep — declares the hero suite's contract for test-file scaffold coverage.</item>
