- 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
- Add the PlatformBinding rule that binds a mock platform for a class or method, unbinds on teardown and restores the previous binding
- Add the PlatformLeakGuard rule that fails a class when a platform is still bound or a service is still registered at class start or end
- Add IrisRuntimeState so the guard reads the registered services without adding a test-only method to the SPI
- Replace the inline mock-platform setup and teardown of twenty test classes with the rule
- Guard the remaining sixty-four platform and service touching core test classes
- Rename the pack-compat pool fixtures to PackCompatFixtures so the two CompatFixtures names cannot collide
- Scope BukkitTestServer branding to a ServerBranding rule that restores the shared mock after each test
- Add Durability, a process-wide fsync policy defaulting to real barriers and switchable to relaxed through the iris.durability system property
- Route the history, studio, journal, structure and datapack fsync barriers through Durability so relaxed mode skips both the force and the channel open
- Add the DurabilityMode test rule and enable relaxed durability on the twenty slowest core stores tests
- Split GenerationHistoryTest into epoch, legacy adoption and recovery classes over a shared GenerationHistorySupport base
- 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
- Read the modded bukkit-supertype baseline from core/purity-allowlist.txt
- Match nested classes against their top-level source entry
- Exempt VolmLib classes, which Iris' core ratchet does not govern
- Delete the hand-frozen knownBukkitSupertypeClasses inventory
- Drop outputs.upToDateWhen and outputs.cacheIf from the loader jar Exec tasks
- Declare lombok.config, core/agent and both revision scripts as modded inputs
- Add gradle/runtime-relocations.gradle as the one runtime-download relocation map
- Read the slimJar relocations and shrinkRelocations from that map
- Pass the derived relocation prefixes into BukkitArtifactVerifier
- Drop the duplicate jar size check the packaging audit already enforces
- Add minecraftPurityRatchet over core/minecraft-purity-allowlist.txt, wired into check
- Register both purity ratchets from one closure instead of duplicating the scan
- Prune WorldCreationProgressReporter from core/purity-allowlist.txt
- Wire the ProGuard shrink pass into the Bukkit artifact with the core, Bukkit plugin and NMS compile classpaths as library jars
- Map the fourteen SlimJar relocations so runtime-downloaded libraries resolve under their relocated names
- Add packaging/shrink.pro keeping the public API, Iris events, platform SPI, VolmLib integration contract and Bukkit event handler lists
- Lower maximumBukkitArtifactBytes to 7,600,000 so verifyBukkitArtifact enforces the same budget as the packaging gate
- Build VolmitSender.name() from the sender name instead of the relocated CommandSender.name() reference, which cannot resolve on Paper 26.2
- 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
