- Defers a chunk update pass while saved biome information is loading and retries it on a later pass
- Forgets only the updates already applied so a retry never refills a chest
- Propagates engine failures from loot application instead of marking the chunk done
- Stops downloads, protocol, pregen, tools and services at server stopping
- Keeps engines, mantle, generation history, the generation pool and burst pools open while the loader drains chunk generation
- Closes each engine when its level unloads and sweeps the rest at server stopped
- Logs a failed level unload instead of aborting the loader's level close loop
- GenerationClosedException covers closed history routers, stages, saved biome runtimes and admissions
- It also covers ownership stores, hydrology caches and engine runtimes
- GenerationFailures tells engine, lifecycle, executor and JVM failures from content failures
- Engine failures rethrow from object, cave object, procedural, floating, upper and decorator catch sites
- Biome layer, noise bound, rotation and mantle write catch sites rethrow them too
- Only content failures are skipped
- A source plan is never cached or persisted without an object a healthy engine places
- A transient engine failure no longer turns imported features off
- Matches the volmlib$ handler names of the client world-open and world-type mixins
- Keys expected mixins by their mixin config file and reports the target class name
- Verifies every expected handler is an injector declared by its mixin class
- Requires every registered volmlib mixin to be audited or deliberately unaudited

- Fabric uses loader 0.19.5 with Fabric API modules from 0.161.0+26.3
- Forge uses 26.3-66.0.8 with ForgeGradle 7.0.40
- NeoForge uses 26.3.0.33-beta with ModDevGradle 2.0.147
- Modded forced datapacks use the 26.3 data fixer and pack format 121

- Bug template offers 26.3, 26.2 and 26.1.2 with current loader examples
- Plugin api-version comment covers 26.1.2 through 26.3
- 26.3 custom biomes write natural_mob_spawns as an overlay modifier with its argument, matching vanilla biomes
- NeoForge biome modifiers can add spawns to Iris biomes again
- The 26.3 custom biome codec test checks the overlay modifier
- The modded structure-state biome lookup resolves from the natural true biome stream, the same as the Bukkit ring search
- Stronghold ring placement no longer plans hydrology tiles around its 128 positions, so chunk structure starts stop waiting on river plans out to ~24k blocks
- Ring lookups are cached per runtime and cleared with the other biome caches
- The modded chunk generator hands VolmLib the bound loader for chunk-generation creature checks
- Each loader build tests its spawn position check: Forge and NeoForge fire MobSpawnEvent.PositionCheck and honor a denial, Fabric applies the vanilla rule and obstruction checks
- The forced datapack, datapack commands, and world check render biomes and dimension types with the 26.3 data fixer and pack format 121
- Modded tests use the 26.3 feature, placement, spawner, sign, and biome resolver APIs
- The water spawn test binds a blocks_motion fixture so solid waterlogged blocks still obstruct spawns
- Fabric, Forge, and NeoForge build against Minecraft 26.3 with Fabric Loader 0.19.5, Forge 26.3-66.0.8, and NeoForge 26.3.0.33-beta
- Fabric API modules follow fabric-api 0.161.0+26.3, ForgeGradle is 7.0.40, and ModDevGradle is 2.0.147

- The fallback resolves on first unset read
- Bukkit chunk generator supplies plains
- Core keeps no new Bukkit coupling
- Modded platform gets registry access from the modded server factory
- Engine bootstrap and tile parity test get tile readers from the modded server factory
- Registry access tests build through the modded server factory
- Object source plans are packed per destination and built once
- Source plans retire once every destination in reach consumed them
- Rotated block states and property variants are memoized
- Generation history syncs to disk from a background group commit
- History syncs at world save, shutdown, pregen end and promotion
- History capture reuses per-column biome and mantle reads
- Semantic summaries are built only when read
- Hydrology plans the whole pregen area nearest first
- Chunks without hydrology skip composition and cave cell lookups
- Server-thread stand-in hydrology answers are never cached
- Neighbour drafts stay inside the planned pregen area
- Terrain3D caches are lock-free
- Cave density lattice samples are shared between neighbouring chunks
- The eager carve window is 27 by 27 chunks with on-demand terrain beyond it
- Cave cells are copied once per chunk for the carve stage
- Terrain columns are painted z-major with per-level ore bands
- Deposit clumps that cannot place are rejected before building
- Dead biome inject writes are gone
- Chunk output buffers track each column top
- Engine getters use a thread-id frame table
- Pregen keeps region border chunks until neighbouring regions finish
- Mantle reads take plate pins so saves cannot close plates in use
- Chunk generator reports generation failures to the running pregen job
- Pregen methods forward generation failures to the async method
- Async pregen fails every outstanding request through an in-flight ledger
- In-flight requests settle once and ignore late completions
- Pregen aborts with the failing chunk as its cause
- Admission drain waits with a 60 second deadline
- Closing the admission gate fails leftover requests
- Tests cover failure propagation, the ledger and the drain deadline
- Dry layers keep head and ceiling equal to the bed after the transition taper
- Displaced layers that dry out also keep head and ceiling at the bed
- Transition displacement reads its datum from the original fluid head
- Tests cover dry banks and drying channels across a transition band
- Language asset test locates the directory through the English file
- Structure template test reads the mixin class bytes instead of loading it
- Water spawn test initializes block state caches before running
- Logging policy check runs after the native sources are unpacked
- Native class boundary check runs after classes compile
- Modded jars ship pack.mcmeta for client resources and mod data
- Modded jars bundle jlibdeflate and its native libraries
- Artifact check requires pack.mcmeta and the jlibdeflate entries
- Artifact check rejects client language resources without pack.mcmeta
- Test loads the pack metadata against the current Minecraft formats
- Modded platform hands the running server to registry access
- Tile reader is built from the running server
- Registry test covers startup, reload and shutdown of dynamic registries
- Every getChunk(..).use() site calls Mantle.useChunk, which cannot fail because a save closed the chunk in between
- Covered-chunk cleanup, custom block and static object layers take their chunk through useChunk
- Discovered flag writes go through Mantle.flag instead of an unpinned chunk
- Test mantles stub useChunk the way the real one behaves
- PregenChunkRetention holds every chunk in a FULL request's dependency square until all in-area regions reaching it drained; drained regions keep only the border strips undrained neighbours need
- Removes the unload/reload churn (about 1.5 reloads per generated chunk at r1000: lattice passes, next region's border, future-region and ring protos)
- Capped at one chunk per MB of heap; over the cap the drained strips farthest from the active region are released; heap pressure and close release everything
- Regions still save and unload at drain; the early-unload test now pins that plus border retention
- A demanded owner missing from the owner cache is restored from its planned tile (resident or prepared-plan store) instead of drafted again
- Same restore path as persisted tiles; plans identical
- Plans real pack tiles headless and prints a digest per tile with planning CPU
- Optional pregen radius plans them under a pregeneration scope and prepared-plan store
- Expected-digest file fails the run on any changed plan
- ChunkBlockUpdateListener remembers the last state with no update or custom effect
- Plain terrain runs skip the per-block isUpdatable and isCustom checks
- Test replays random writes against the per-write catch semantics
- 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
- Pregeneration scope limits the lower-rank neighbour drafts an owner starts early to tiles the area composes from
- Undemanded ring drafts (and the early neighbours they started) are no longer computed; demanded ones still resolve on demand
- r2000 tile set: 80 -> 54 drafts, planning CPU -32%, plans identical
- 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
- ColumnExtentListeningHunk reports writes through a primitive listener instead of boxing ListeningHunk
- Palette layer generators memoized per seed slot instead of one shared recent entry
- Paint chunks z-major so neighbouring columns share block-buffer cache lines
- Fill the solid run below layers, river paint and cave ceilings with ores or rock in one loop
- Resolve chunk constants, air and bedrock once per chunk; drop the unread shared lastBedrock write
- IrisOreBands replaces IrisOreGeneratorBounds: per-Y candidate generators in list order
- Resolve a constant (FLAT) ore chance once instead of sampling it per block
- Column parity test against the per-block algorithm over randomized columns
- close reads each window slot before the atomic swap instead of swapping all 5,929 slots
