- Saved-biome loading defers chunk update passes
- Mixin audit handler names are checked against the compiled mixins
- Teleports wait up to 120 s and report the real failure
- Capture original biomes at Fabric mod init so generated biome definitions exclude Fabric biome modifications
- Test the generated definition against a biome modified in place the way Fabric does it
- Bootstrap audits vanilla slots that hold an Iris world
- Startup stops when such a slot has unusable history
- Startup also stops when bukkit.yml no longer binds such a slot to Iris
- The audit detail carries the history read cause
- File system failures are named by type
- Bootstrap failures print the refusal banner instead of a bare stack trace
- A vanilla slot holding an Iris world is told to restore its history and keep its binding
- The vanilla slot remedy adds deleting level.dat when the level was never created
- A failed enable locks only for bukkit.yml worlds the server loads
- Mantle-bypass maintenance starts only after players leave the world
- This covers studio close, studio disable, world remove, world unload and create rollback

- Ends a level's pass only when its engine or mantle is closed
- Covers the deferred, permanent and isolated update paths through updateChunk and the server tick
- Waits for the destination chunk without a wall-clock deadline so a cold first chunk no longer fails the teleport
- Reports the failure cause, an unloaded dimension, an offline player or a refused teleport separately
- Adds the new messages to every locale
- 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

- 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

- 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
- Modded logins are refused only when this save's dimension registry lists the primary world
- Otherwise Iris warns once and leaves routing idle
- An unreadable dimension registry counts as expecting the primary world
- A vanilla slot bound to Iris without Iris storage points at the bukkit.yml entry and /iris replace
- The refusal consequence comes from whether startup worlds exist instead of the first tick
- The first WorldLoadEvent or a hotload marks startup worlds as existing
- A failed enable on a hotload says the server keeps running
- Reconciler resolution failures report the refusal banner
- Operators get a join notice for such failures until the world loads
- The fail-closed generator is built even when the cause message cannot be read
- Tests drive Iris.onEnable for the lock, the unsupported-server lock and the rethrow
- The failed-enable teardown decision lives in FailedEnableLock with a test
- Pass the modded loader into the generation registry so biome modifier output stays out of validation
- Cover Forge modifiers on climate, attributes, effects and features against the canonical definition
- Every Iris world the Bukkit resolver cannot serve gets a fail-closed generator
- CraftServer no longer receives a throw that it turns into vanilla
- A refusal banner logs the world, key, cause chain and what happens next

- Tests cover semantic round trips for every supported fixer
- 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

- 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

- 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

- 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

- 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

- Over the plate cap, the least recently used idle plates are saved one at a time on the IO pool while submissions continue
- Submissions wait only past the cap plus a small overshoot
- Replaces trimming and unloading every idle plate, which evicted the active working set and read it back
- eager terrain window covers the replayed object sources plus one chunk of footprint (radius 13 instead of 19 for overworld)
- content writers generate a chunk's missing terrain components before handing it out, so reads past the window stay identical
