- Flat authoring studios skip terrain and native structure preparation
- Normal Studio entry prepares the exact hydrology column asynchronously
- Hydrology prefetch admits the complete frontier before stale queued work
- Concurrent hydrology loads avoid cache monitor contention
- Cave density tasks drain failures before releasing chunk state
- Terrain and interpolation queries reuse exact bounded samples
- Pregeneration counts requested chunks directly from its bounds
- World-local pack epochs preserve generated chunks across restart-only updates
- Kernel catalogs and source seals retain executable generation behavior across jar changes
- Crash-safe ownership, boundary, registry, semantic, and mantle records survive activation changes
- New terrain blends lower surfaces and inverted ceilings against frozen historical boundaries
- Cave, object, structure, biome, and hydrology work respects activation ownership
- Find commands merge recorded facts with eligible active predictions for biomes, regions, structures, objects, and rivers
- Bukkit, Fabric, Forge, and NeoForge route generation through retained runtime scopes
- Shutdown ordering preserves class-loader resources until world and service cleanup finishes
- Tests cover activation chains, failure recovery, retained registries, bounded lookup, and transition geometry
Vanilla structure and feature placement now runs through the bounded
worldgen access with a protected-position predicate, so a jigsaw piece
or an imported feature can read a static object's blocks but never
overwrite them, and never schedules a tick or block entity there.
Dimensions without static objects keep the plain level as before.
