- saved biome capture resolves each quart column through one engine call
- column-invariant height, region, surface and cave fallback resolved once
- cavern reads use one pinned mantle chunk per column
- saved biome cells interned per capture
- engine getters borrow the bound route runtime for other chunks instead of opening a stage
- dimension stack metadata clearing and continuation restore rewrite cavern cells after sCave, so they drop the context snapshot and decoration re-reads the mantle
- test that decoration reuses only its own chunk's snapshot
- boundary columns build runs directly instead of voxel lists, tree sets and hash maps
- palette sorted once per column with a direct comparator, same canonical order
- geometry source reuses the last encoded voxel
- equivalence test against the previous encoding
- close reads each window slot before the atomic swap instead of swapping all 5,929 slots
- terrain-ready flags live with the terrain access and exist only on content writers
- Over the plate cap, the least recently used idle plates are saved one at a time on the IO pool while submissions continue
- Submissions wait only past the cap plus a small overshoot
- Replaces trimming and unloading every idle plate, which evicted the active working set and read it back
- eager terrain window covers the replayed object sources plus one chunk of footprint (radius 13 instead of 19 for overworld)
- content writers generate a chunk's missing terrain components before handing it out, so reads past the window stay identical
- getEagerInputRadius replaces isInputGenerationLazy
- sCave copies the chunk's cavern and hydrology terrain view once (journal originals win) instead of per-voxel monitor, journal and slice lookups
- hydrology lookups answer null without work in chunks with no cave cells
- decorateNaturalCaves reuses the sCave snapshot through the chunk context
- Each thread keeps its recent final hasColumnsAround answers next to its chunk slots, so the object and hydrology gates skip the nine-chunk scan on repeat
- 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
- Index planned tiles by occupied chunk; empty chunks skip composition, tile residency and cave-cell lookups
- Plan the whole pregen area nearest first with several roots, past the tile budget when plans persist
- Restore persisted tiles without a planning root permit
- Never memoize answers the server thread gave before its hydrology plan landed
- 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
- Cache vanilla withProperty variants per state
- Cache rotated states per rotation and quantized spin
- Hoist the stilt dirt state and rotate only target-layer stilt blocks
- Store source plans as packed per-destination cell runs over a value table
- Weigh shared payloads once and give tiles and markers finite weights
- Release a plan once every touched destination consumed it, keeping its index
- Rebuild only on repeated consumption; debug stats for builds and waits
- 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 export tasks copy the selected artifact
- The previous plugin packer is removed
- The agent tracks primary storage closure during Spigot shutdown

- 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
- ItemsAdder API resolves from Maven Central
- Integration repositories only resolve their assigned groups and modules
- Shared VolmLib classes and packaging use the same pinned revision
- JitPack builds and publishes with remote dependencies
- Local Maven publication uses art.arcane:iris with the configured version
- API generation tracks the final archive filename lazily
- API jars retain signatures and metadata with valid throwing method stubs
- Publication tests verify metadata, bytecode, and consumer compilation
- 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
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.
- Resolve IrisTerrainNormalActuator by keeping master's primitive riverWaterSurfaceStream lookup and primarySurfaceLayerOrNull accessors while retaining the terrain column, span, layer surface and ceiling locals that write air through terrain3D gaps
- Resolve HydrologyFootprintCompiler by keeping the MaterializedSurface planned-surface record with terrain ownership beside master's package-private SurfaceRasterIndex, which retains its ownsTerrain override
- Resolve HydrologyCaveContainmentPlanner by dropping the nested RecordingCaveVoxelView, SurfaceObservations and ViewObservations types that master promoted to their own files
- Port the surface-observation ownership check into CaveSurfaceObservations so cached cave validations replay both height and ownership observations through Observation.matches
- Resolve PackExportClosureTest by keeping master's retirement of the source-text packager guard while retaining the snippet export tests, and restore the Files and Path imports those tests use
- Resolve IrisBiomeLayerSlopeSourceTest by folding the lower-ledge slope palette case into master's lockLayers parameterization
- Recapture the studio schema digest for the terrain3D biome property, its IrisTerrain3D definition, the terrain-3d snippet enumeration and the reworded upperDimensionCarving description, verified by reconstructing the previous digest from the stripped schema
- Add an optional per-biome `terrain3D` profile with density and fissure noise styles, amplitude, horizontal and vertical feature scales, crack depth, width and scale, slope and fluid-clearance gates, and a seed offset, each range-checked before use
- Add a terrain runtime that samples the signed density and fissure fields on a four-block lattice around the biome's generated height and resolves each column into solid spans, so surfaces gain projecting rock, undercuts, ledges and narrow cracks that fade out on flat ground and near the fluid line
- Remove unsupported rock by flood-filling span components across neighbouring columns and dropping any fragment of 512 blocks or fewer, while larger connected masses are kept
- Report the shaped column top as the natural terrain height, keep the unshaped generator height available as a separate stream, and measure surface slope between neighbouring ledge floors instead of the flat heightmap
- Write air through the gaps in the normal terrain actuator, generate a fresh surface palette for every ledge floor, and paint ceiling layers beneath undercuts
- Carry each layer's own column through the dimension stack and upper dimension so stack top heights, solidity and surface lookups follow the spans, and each exposed face draws its palette from its own source height and slope
- Sample a layer's slope condition once per column at the surface being generated, and gate surface decorators on the slope of the ledge they sit on rather than the column heightmap
- Decorate every exposed ledge floor and the ceiling above it during the decorant pass
- Treat shaped openings as surface rather than cave when resolving biomes, skip them during cave carving, suppress cave zone markers inside them, and resolve their boundary biome from the surface biome stream
- Include shaped openings in mantle carve queries and carved columns, fall back to terrain solidity for surface-solid checks across stack, upper and normal terrain, and answer both queries from the island mask when placing objects on floating islands
- Let the hydrology planned surface report whether it owns a column, so the cave voxel view consults natural terrain solidity where hydrology does not own the terrain, and split replayed plan observations into height and ownership records
- Validate `terrain3D` on biomes and `snippet/terrain-3d` snippets as a blocking pack error, rejecting unknown fields, wrong types, out-of-range numbers, unknown noise styles, style nesting past 32 levels and snippet references that escape the pack
- Copy the whole snippet tree during modded studio pack export through one shared routine instead of only `snippet/style`, so terrain and nested style snippets survive export
- Add a terrain probe and Gradle task that generates real pack chunks, compares predicted column geometry against the actual blocks, requires retained overhang coverage for named biomes, reports detached-component topology, and writes cross-section images with a JSON summary
- Enumerate image-mapped regions and skip compat-excluded ones when collecting biomes for stacked and upper dimension terrain
- Remove the accessor allocation comparison whose per-call byte counts depend on escape analysis timing and failed under load, keeping the three behavioral accessor tests
- Make IrisInterpolation extend the VolmLib IrisInterpolation and delete the nine numerically identical statics it duplicated: hermite, cubic, bicubic, bihermite, trihermite, tricubic, lerp, blerp and trilerp
- Keep the Iris rangeScale because the VolmLib copy short-circuits bmax == bmin and generation output must not move
- Ship the VolmLib IrisInterpolation and InterpolationMethod by removing their unusedVolmLibClasses entries
- Make StorageHunk, ArrayHunk, AtomicHunk, SynchronizedArrayHunk, AtomicDoubleHunk, AtomicIntegerHunk and AtomicLongHunk extend their VolmLib counterparts and only bind the Iris Hunk interface
- Drop the Lombok data, equals and hashCode generation the duplicated storage hunks carried
- Ship the VolmLib storage hunks by removing their unusedVolmLibClasses entries
- Delete unused board BoardSettings and ScoreDirection wrappers around the VolmLib board types
- Delete unused inventorygui UIStaticDecorator, Window and WindowResolution wrappers around the VolmLib inventorygui types
- Delete unused VectorMath subclass of the VolmLib VectorMath
- Delete unused InterpolationType enum and the IrisInterpolation blerp overload that keyed on it
- Delete HunkFace and point Hunk.viewFace and Hunk.cropFace at the VolmLib HunkFace
- Drop the iris board and inventorygui excludes from supersededVolmLibPackages and the VectorMath entry from unusedVolmLibClasses
- Drop the deleted inventorygui files from the Bukkit purity allowlist
- Remove VectorNoiseKernels2D from requiredBukkitArtifactEntries; the class was deleted with the unwired 2D kernels and verifyBukkitArtifact failed on every build
