- frames live in a 256-slot table indexed by thread id, ThreadLocal only on slot collisions
- the single ThreadLocal probed long collision chains in the workers' thread-local maps
- Semantic journal and saved-biome appends write without forcing; a shared flusher forces touched files within 2s outside every store lock
- GenerationHistory.sync forces pending history at world save, engine shutdown, pregen completion and before activation promotion
- A failed deferred force poisons the store the same way an uncertain append did
- Cache the active epoch pack root instead of regex-validating it on every stage open
- Tests pin append-without-force, sync barriers, failure poisoning and the save, shutdown and pregen hooks
- Ellipsoid footprint dry run replays the build draws without building
- Terrain-scoped clumps above every column limit are dropped before building
- Surface biome filters no chunk column passes skip the deposit
- parent biome lookups read the biome stream directly instead of building the boundary field
- fields are only built where a parent with floating children needs edge distances
- Bukkit noise generation keeps one biome per column until a partial column write
- drops the full-resolution biome array allocation and fill per chunk
- ChunkDataHunkHolder stores cells in a plain array and tracks each column's highest stored y
- natural cave decoration and perfection stop scanning above the column top
- sBiome, floating biomes and publishNaturalMetadata no longer write MatterBiomeInject; nothing reads it
- stack metadata clearing only runs for dimension stacks
- Version is 4.1.2-26.2 across platform builds
- Plugin builds use shared automatic jar selection
- Native adapters remain bundled in selected artifacts
- Plugin export tasks copy the selected artifact
- The previous plugin packer is removed
- The agent tracks primary storage closure during Spigot shutdown
- Limit terrain cleanup to affected columns and batch cave boundary reads.
- Reuse offline generation workers and native air states.
- Gather history writes and defer unpublished append synchronization until atomic publication.
- Cover terrain parity, worker lifecycle, history durability, and publication failures.
- Startup holds generation admission through recovery and runtime attachment
- Prepared startup state removes the second recovery scan before generator readiness
- Recovery batches allocated chunks by region with reusable snapshot buffers
- Region decoding uses up to four workers within processor and heap limits
- Oversized regions and external chunks use bounded direct reads
- Status parsing validates chunk coordinates without constructing the full NBT tree
- Region snapshots reject changed files, allocation headers and truncated payloads
- Native zlib decompression uses jlibdeflate with a Java inflater fallback
- Chunk readers reuse region handles and decompression buffers during recovery and boundary capture
- Semantic shards reuse validated summaries with invalidation on mutation
- Semantic key validation avoids regular expression allocation
- Saved biome indexes use buffered sequential reads with reusable CRC state
- Pack inspection reads validated manifest and pack state without opening terrain indexes
- Datapack compilation reuses pack inspection within each operation
- Kernel staging avoids duplicate pack hashing when no activation is pending
- Pack copying and directory synchronization use up to four available processors
- Boundary publication batches directory synchronization around durable catalog publication
- Configured world reconciliation reuses ready runtimes after identity and saved-state checks
- Explicit world loads retain the full validation path
- Regression tests cover startup admission, recovery, malformed data, resource limits, publication and reconciliation
- Invalid language updates retain the last valid messages
- Malformed startup catalogs use English defaults
- Unrelated reloads preserve personal language caches
- Deleted locales use English without changing saved choices
- Restored locale files resume their translations
- Language catalogs include shared editor titles and remove obsolete usage messages
- Packages regrouped by domain: generation, world, pack, studio, structure, platform, command, localization, diagnostics
- Forked VolmLib utilities dropped for the shared library: noise, stream, interpolation, hunk, matter
- Engine-coupled stream decorators moved to generation.stream.GenerationStreams
- Hunk section splits now run on the Iris burst pool through HunkBurst
- Artifact entry lists, purity allowlists and shrink rules follow the new paths
- Debug dump replaces the root debugdump command
- Debug toggle controls diagnostic logging
- Debug version uses the shared version display
- Root version remains executable but hidden from help
- Diagnostic dump routing retains its separate permission path
- Translations and tests cover the revised command structure
All 17 translations now use editable TOML files
Language menus and debug messages include translations
Headers explain all 243 variables, prefixes, colors and formatting
Generated guides refresh without overwriting customized messages
Missing or invalid messages fall back to English
Language reloads preserve server and player selections
Jars include localized guides and required TOML support
Surface hydrology policy split, native terrain height cache, watched-edit
hotload cancellation, world-save requestSave with tracked ownership flush,
background-task drain that follows saves admitted mid-drain, peaceful spawn
guard, cached-completion terminal state, IO drains off the owner thread.
Studio pregen at scale: detached historical runtimes keep the configured
noise cache instead of the Studio-wide cache; retired runtimes are no longer
pinned by the volumetric fragment filter's per-thread scratch; pregen mantle
cleanup and native region flushes run on per-run threads instead of the
server thread and the shared Iris IO pool (the flush on the IO pool starved
tectonic plate loads and wedged every Paper worker in Mantle.getChunks);
background-task cancellation claims tasks atomically.
