- 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
- Replaced the nine static final PlatformBlockState fields in IrisDimensionStackActuator, IrisTerrainNormalActuator, IrisPerfectionModifier, IrisPostModifier, IrisBiomeLayerGenerator, BiomeBuffetGenerator, ChunkDataHunkHolder and EngineMantle with BoundBlockState holders that re-resolve when a different platform binds, costing one volatile read of the cached binding, one of the bound platform and a reference compare per read
- Turned the IrisPerfectionModifier ore-hiding table into a Map of BoundBlockState so the four base states follow the bound platform instead of the first one loaded
- Kept the last resolution in BoundBlockState while nothing is bound so in-flight generation on an unbinding server reads the same states it did before, matching what B.registries already does
- Added IrisPlatforms.getOrNull so the block-state holders read the binding once without an exception on a bare JVM
- Added PlatformStateRebindTest, which fails on the old code: it binds two mock platforms in turn and asserts ChunkDataHunkHolder and EngineMantle serve the second one, and rejects any static PlatformBlockState field left on the converted classes
- Indexed the .iob write palette by key so palette lookup is a hash probe rather than a scan of the palette list, cutting the 32767-state IrisObjectIoWriteLimitsTest from 4.9s to 0.7s while writing byte-identical files
- Built the palette once per write instead of once in validateWritable and again in the writer, and shared it between the plain and progress-reporting write paths
- Added IrisObjectIoPaletteTest, which pins the SHA-256 of a 30000-block, 3011-state object written by the previous implementation and asserts the palette keeps first-seen insertion order
- Added BukkitTestServer, a single mock Bukkit server installed once per JVM under a lock, stubbing logger, name, version, plugin manager and both createBlockData overloads, and failing loudly if the install does not take
- Moved IrisRuntimeSchedulerModeRoutingTest, WorldRuntimeControlServiceTimeLockTest, PreObjectMatterTest, CNGInjectorParityTest, BukkitSpiConformanceTest, MantleWriterPreObjectJournalTest, IrisFloatingChildBiomesCarvingResolutionTest and IrisDimensionCarvingResolverParityTest onto it, so whichever class runs first no longer decides whether createBlockData or getPluginManager is stubbed
- Extracted the KeyedBlockState test double out of IrisObjectIoWriteLimitsTest so the palette test can reuse it
- Replaced the IrisServices.clear() teardowns in nine test classes with a targeted remove of the PreservationRegistry each one registers, so a teardown no longer wipes a binding it did not install
- Registered a PreservationRegistry in PackDownloaderTest and StudioSVCWorldPackPublishTest, which reach IrisData.get and openRuntime and were silently getting loaderless IrisData whenever no other class had leaked one
- Removed the core processResources skip that fired on test-only invocations, which packaged a core jar with no generation kernel catalog and made all 10 probe and bukkit-plugin tests that reach GenerationKernelRegistry fail on every ./gradlew test
- Set maxParallelForks on :core:test to half the available processors, overridable with -PtestForks, and left the small modules single-forked so they do not re-pay the Minecraft bootstrap per fork or steal worker leases from core
- Resolved B.registries() per bound platform instead of latching the first one for the JVM lifetime, keeping the previous unbound behaviour, so a test that binds its own platform no longer reads a foreign platform's block states
- Resolved IrisObject.States per bound platform through accessors instead of static finals fixed at class-init, removing the NoClassDefFoundError and null material-key failures that appeared whenever class partitioning changed
- Bound an explicit platform in EngineMantleCoverageTest and IrisDimensionStackActuatorMetadataTest so they no longer depend on another class leaking a binding first
- Gated BukkitSpiConformanceTest registry probes on a live RegistryAccess and restored the IrisPlatforms binding it leaked, which was silently swallowing the stderr two SettingsHotloadWatchTest assertions read
- Initialised org.bukkit.Registry and Biome inside the RegistryAccess mock scope in ObjectStudioGeometryTest so Mockito no longer instruments Registry mid-clinit
- Replaced the SettingsHotloadWatchTest fixed 1200ms diagnostic window with a 10ms condition poll bounded at 4s
- Replaced the IrisCaveCarver3DNearParityTest wall-clock speedup benchmark with a deterministic density-sample count, cutting 28 carves to 2
- Cut HydrologyPlannerTest cold-owner parity from 12 tile plans to 4 and shared the immutable baseline plan across the early-owner tests
- Built one prototype project or staged history per class in the jigsaw studio and world replacement tests and copied it per test, replacing repeated fsync-bound fixture construction
- Replaced Mockito block-state fixtures with concrete implementations in the object IO, deposit modifier and nearest-block-index tests, removing about 2.5 million interceptions
- Replaced Thread.sleep with bounded condition polling in HydrologyTileCacheTest
- Deleted 19 test classes and 60 further test methods that asserted on production .java source text rather than behaviour, and removed the 19 now-unread iris.*Source system properties that fed them
