- Object placement bakes split into one per-object layout (palette, tiles, canopy) and per-variant offsets
- Variants beyond the per-object limit are built transiently instead of clearing the variant map
- High-variant golden and no-rebuild tests
- Cell lattice passes gather every missing corner sample of the pass and evaluate base, detail and modules through NoiseProgram.fillPoints3D

- Build source plans from a log slice
- Journal commit originals in a packed-key set instead of a linked map
- Buffer cave object writes in parallel arrays

- Build every free source plan before waiting on plans other threads are building
- Reuse TreeBlockMaterial values per block state
- Layer and generator programs sample single points through NoiseProgram.sample2D
- Scalar interpolator group means use the compiled programs when the seed matches
- Single-point program heights are property-tested against the generator path
- Add SectionBuffer: chunk palette of written instances and short[4096] ids per section in y, z, x order
- Column tops are indexed per x-slice and padded so fan-out slices do not share a cache line
- Add ColumnRunHunk and forward column runs through the listening hunk and block update listener
- Terrain painter emits column runs and evaluates ores only inside the column's ore bands
- Bukkit generation writes into SectionBuffer and applies it through ChunkDataOutput
- Remove ChunkDataHunkHolder and the probe's ProductionBlockHunk copy
- Probe production buffers use SectionBuffer
- Bake rotated block offsets, palette indexes, tiles and canopy bits per object and spin kernel
- Resolve decay, rotation, waterlog and air facts once per palette entry per placement
- Skip the destination read for waterloggable states that cannot become waterlogged
- Move SpinKernel to its own file
- Facade reads reuse the thread's last chunk entry instead of probing the bake map
- Stores and full-chunk fills refresh that entry from the map
- Surface lattice lookups reuse the previous point's cell indices
- Rarity stream picks are property-tested against the VolmLib rarity selection
- Pregen capacity growth scales the bake by the same factor as engine start
- Cell kernel passes fill a per-pass density lattice in field-major batches before classifying rows
- Lattice density columns are shared between profiles with identical density fields
- Warp samples are shared between profiles with the same warp field and batch along lattice columns
- Added lattice read, sample and warp counters
- Added bit-exact lattice column and field sharing tests
- Rarity selection streams pick from precomputed cumulative tables
- Implode and surface biome fixes take primitive coordinates
- Child selection reuses one derived child seed instead of a new RNG per level
- Base biome selection reads bridge and inferred streams directly
- Planes fill lazily per column with ready bits and batch only missing columns on full-chunk requests
- Natural fills batch only the base heights Terrain3D still needs and reuse the sparse memo
- Bounds lattice and hydrology planner reads stay out of the bake
- Bake capacity is eight times the noise cache, covering the measured working set
- Generator evaluation counters and a bake census print from the probe
- Parity test compares batched chunk base heights and evaluation counts with the scalar path
- Generation pool sized to performance cores
- Pregen burst raise sized from performance cores
- Hydrology planner pool sized to performance cores, at least four
- Compiled generator programs evaluate layer trees in batches through NoiseProgram
- TerrainProgram accumulates interpolator group means over chunk columns
- ChunkBakeCache holds compute-once per-chunk planes with provisional results never published
- Height, biome, region, rock, fluid and cave streams read the bake as thin facades
- Sparse hydrology and bounds reads stay scalar with a direct-mapped base height memo
- ColumnBake assembles id planes, heights, fluid surface, columns and the apron on demand
- Use the radial three-dimensional bound whenever rotateTowardsSlope is set, including placements whose configured rotation is disabled
- Group the support read margin helper with the other static factories
- Fell back to per-group grid sampling when a height sample nests inside another on the same thread
- Covered nested sampling with a bit-exact parity test
- Add PlacementReach: centered half-extent reach from loaded object keys, scale and shrink chains, enumerated rotation kernels, translate, warp and vacuum
- Size the object pass write radius and read radius from PlacementReach instead of full object width
- Size floating reach from scaled and shrunk object spans
- Count cave profile vacuum modes and upper-dimension effective rotation in the object reach
- Keep the transition-band footprint check on its existing footprint
- Add runner-backed and pack-wide reach tests
- Classify mixed cells without fade, boost or protection through a branch-light column loop
- Hoist the per-row bilinear terms shared by every column of a cell row
- Mark open cells from the pass bitset when every pass column is active
- Read interpolator corner bounds through a per-thread chunk block and skip groups whose cell corners are all zero
- Prefilled chunk context caches inline on generation threads with heights ahead of biomes
- Kept the burst-pool prefill only for the platform main thread, with heights and biomes in one task
- Painted surface fluid from the chunk context cache instead of re-sampling the fluid stream
