Module region 

Region access for chunk feature generation.

Feature placement needs the center chunk plus its direct dependencies, while writes must stay inside the stage’s block-state write radius. WorldGenRegion centralizes that contract so feature, structure, and vegetation code cannot bypass the chunk pyramid.

Structs

CachedWorldGenChunk 🔒

CachedWorldgenHeightmaps 🔒

WorldGenBulkSectionAccess 🔒

Cached section-level access for feature code that mirrors vanilla BulkSectionAccess.

WorldGenChunkRef 🔒

A generation dependency with access semantics captured when it was acquired.

WorldGenRegion

Chunk-cache backed worldgen view for the current generation step.

WritableSectionKey 🔒

Enums

WorldGenAccessMode 🔒

The access mode is captured when a generation dependency is acquired.

Constants

BULK_SECTION_INLINE_CHUNKS 🔒

Size of 8 is fine here because analysis showed that 91.7% only ever reach <=2 and the largest one ever grew was 6. Decreasing the size below 8 resulted in no change in speed.
