The mirror test compared a normalised reading of two spellings and was beaten twice (a statement before the return, gravityHeight's sum). GravityShader writes the whole file (potential, zero-strength guard, reference term, height sum) from GravityField's constant (TailOffset); GravityShaderTests fails on any difference. GravityShaderMirrorTests deleted. GravityFieldParityVerify opens Main Menu.unity: no ZoneRenderer there, its Fog Surface Displacement camera is the menu's own brush presentation (layers 9 and 10) by spec. Builds not yet verified on this commit; verified at the final merge. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
