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.
- 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- Leave the superseded stale-temp ordering comment deleted rather than restoring text the new boot path contradicts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

- 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

- 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
- 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

- 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
