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
- Move each jigsaw subgroup executor into its own top-level command class
- Move the adoption plan store, handlers and helpers into CommandJigsawAdopt
- Move the vanilla export lease and reporting helpers into CommandJigsawExports
- Move the studio open lifecycle into CommandJigsawOpen
- Point the jigsaw contract test at the relocated command types
- Exclude the new jigsaw command sources from the generation revision scope
- Move art.arcane.iris.testsupport into core/src/testFixtures and apply java-test-fixtures to core
- Consume core test fixtures from the bukkit plugin, nms, probe and the three loader adapters
- Delete the duplicate ProjectPaths copies in the bukkit-plugin and modded-common test trees
- Point ModdedMessageContributorTest at the shared ProjectPaths
- Guard CommandPackCompatTest, NativeTransitionColumnTest and StubPlatformStateTest with PlatformLeakGuard
- Release the probe runtime state after DimensionStackSuperflatProbeTest opens a workspace
- Keep core main classes ahead of the core jar on the test classpath so the bytecode gates still scan a directory
- Remove the Javadoc and inline comment blocks the three runtime-safety commits added under src/main
- Keep the GPL file header on the new spi type, matching every other file in that module
- Leave the superseded stale-temp ordering comment deleted rather than restoring text the new boot path contradicts
- Add RuntimeInjection so the Java agent attach and the server-code injection run once, on demand, instead of during every enable
- Install the injection when a world Iris created is about to be built and when Bukkit asks for the generator of a world configured outside Iris
- Lock the runtime with the same reason a boot-time injection failure used to raise when the deferred install fails
- Add general.eagerRuntimeInjection to keep boot-time injection and its startup verification
- Re-read the startup lock after a deferred install so a failed install refuses the world instead of generating it
- Move the stale cache/temp sweep off the boot thread and make every pack import wait it out
- Move the default-pack presence warning off the boot thread; it walks the whole pack tree to pick a warning
- Build the wand and dust templates on the first tick instead of during service enable
- Report enable duration, per-phase timings and the three slowest services on every boot
- Drop the wand and dust templates on service disable
- Null Iris.instance, the console sender, the Multiverse link, the compat set and the chunk tickets at the end of teardownRuntime
- Bind the host bridge suppliers to the constructing plugin instead of reading the instance static on every call
- State that Iris is disabled when service, getTemp or getSender is reached after teardown instead of raising a bare NullPointerException
- Add IrisRuntimeStatics so a disable drops the service registry, both capability singletons, the loaded datapack runtime and the localization roots
- Add WorldLifecycleService.reset and WorldRuntimeControlService.reset so the next boot snapshots the server it is running on
- Add ServerConfigurator.resetLoadedDatapackRuntime so an enable revalidates instead of trusting the previous boot's fingerprint
- Clear the localization data folder and plain-text memo on shutdown
- Add BukkitPlatform.releaseHost and call it last in terminal cleanup so the disabled plugin, console sender and log bridge stop being reachable from a static
- Add art.arcane.iris.spi.CapabilityProbe so an absent optional API is recorded at debug with the failure class and message instead of a bare ignored catch
- Route runtime day-time reads, clock pushes and the noon time lock through IrisLogging.reportError with the world name and the full trace
- Report a level storage access that will not close, so a retained world session lock names its cause
- Report a failed iris.json rewrite with the file path instead of dropping the IOException
- Report Iris world registry and dimension read failures during Multiverse reconciliation instead of logging one debug line
- Report a failed pack compatibility summary and a failed vanilla-slot capture with their traces
- Report a superseded generation semantics shard that cannot be deleted, once, with its path
- Restore the interrupt flag when the global cache trimmer join is interrupted
- Replace ValueWithDiagnostics with CheckResult so a startup check carries the runtime lock reason it raises
- Give every startup check an explicit advisory or critical severity and lock the runtime on any Danger result, replacing the catch that recognised the injection check by id
- Lock the runtime when general.disableNMS holds a no-op binding or the NMS binding is unbound, instead of marking the runtime ready
- Match incompatible plugin names against every registered plugin without regard to case
- Name the JVM maximum heap in the memory check output
- Print the lock reason and what it blocks when Iris enables into a locked runtime
- Carry the per-check safeguard modes and diagnostic lines in /iris debugdump
- Require the core source tree alongside the settings file when walking up for the repository root, so modded-common tests built inside a loader adapter no longer stop at that adapter's own settings file
- Add the Await test helper that polls a condition every ten milliseconds under a bounded timeout
- Replace every Thread.sleep in the fourteen polling test classes with a condition wait, a latch wait or a bounded quiet window
- Keep the crash-consistency fsync interception in GenerationHistoryAdmissionTest and SavedBiomeStoreBatchTest on real barriers
- Add the ProjectPaths test helper that derives the module root from the test class code source and the repository root from the settings file above it
- Replace the working-directory-relative source and resource literals in thirty-five test classes with module and repository lookups
- Drop the bespoke source-root walk in PregenMantleCleanupContractTest
- Delete 22 test classes whose assertions only read production .java text and check call ordering or literal presence
- Remove 77 source-text assertion methods from 34 test classes that keep real behavioural coverage
- Replace the core process-stream source grep with an ASM gate over compiled core classes in CoreProcessStreamPurityGateTest
- Replace the packs-root source grep in PacksFolderContractTest with an ASM call-site gate over compiled core classes
- Replace the IrisData registered-root regex in PackTypeBukkitPurityGateTest with an ASM scan of the registerLoader class constants
- Trim six mixed tests down to their behavioural assertions and drop their source-text tails
- Drop the eight iris.*Source and three iris.moddedCommonSources test system properties now that nothing reads them
- Add a root moddedTest that runs adapters/modded-common through the Fabric build
- Make check depend on moddedTest, ordered ahead of the loader jars
- Gate the buildSrc jar on the buildSrc tests so they stop being skipped
- Drop an unreachable classpath guard from SchemaBuilderPlatformIsolationTest
- Delete stale jars through an injected FileSystemOperations in the root build
- Delete stale loader jars through an injected FileSystemOperations in each adapter
- Resolve stale-jar file trees and copy sources at configuration time
- Expand the loader metadata templates from the configured version string
- 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
- Terrain and cave scans skip repeated work
- River and structure lookups reuse cached results
- Chunk history saves share disk writes
- History lookups continue during disk writes
- Failed saves retain their original errors
- Deposit failures stop incomplete chunks
- Tests check output and save safety
- Server shutdown advances native chunk tasks while waiting for pregeneration
- Native world close owns chunk saves during server shutdown
- Pending plugin flushes stop waiting when native shutdown begins
- Late eviction completion cannot schedule another shutdown flush
- Regression tests cover owner waits and shutdown save ownership
