6 of 8 archetypes ported. This one starts from VOID and FILLS where the other four start from ROCK and CARVE, which is what it was worth doing: neither end of the pile needed a new operator, only the opposite sign. FConstantRockSource -> FConstantFieldSource(+/-Base) AllSolid <-> AllAir FSdfCarveOp -> FSdfConvertOp(Sign = +/-1) carve <-> fill FSdfRoughnessMod 4th archetype, unchanged Only the island blob source is new. Multiplying by +/-1 is exact in IEEE-754, so the three already-green ports are bit-for-bit untouched. ClassifyBox can return AllAir for the first time in the plugin, and an island strate is by construction mostly empty — the test counts AllSolid and AllAir separately so an aggregate cannot hide whether that fired. Two bounds that would have been holes if assumed rather than derived: the island bound is one-sided (a hairline thread of matter hangs below each island down its axis, so only the TOP may reject), and the domain warp displaces X and Y independently, so the pad needs WarpAmp*sqrt(2). Also: AUDIT C1 was NOT closed. The 2026-07-27 sweep matched `SeedF * K` and this archetype's warp spells it `(float)S * K`, so one site survived — at seed 2e9 the warp flattens and every island snaps back to a perfect circle. Fixed in both paths in one pass so the equivalence test stays a valid oracle. Expect island silhouettes to change at large seeds. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
