- IrisDimension borrowedDimensionType reuses an existing registered dimension type instead of generating one
- Pack validation rejects borrowedDimensionType values that are not namespaced registry keys
- Generation contracts record the borrowed type key and capture it as an external registry definition
- Borrowed types bind when the pack min equals the type min_y and the pack top fits, with both ranges in the refusal
- Studio hotload rejects borrowed type changes and the world check validates borrowed ranges
- Forced datapack skips generated types and presets for borrowed dimensions and accepts retained borrowed epochs
- modded.json dimensionTakeovers writes a LevelStem per level key using the irisworldgen:iris generator
- Takeover changes quarantine the level chunk, entity, POI, and Iris data before load and track applied state per world

- Isolate smart-bore variants from shared source objects.
- Pin noise and full-engine output across generation orders.
- Verify same-jar generation through cold server restarts.
- Test that capture drops generation timings once generation is idle
- Test that capture carries the engine timing averages while fresh
- Remove the hand-built idle snapshot test that passed without the gate
- Publish in-flight pregen chunk requests as iris.pregen-queue
- Publish chunks left in the job as iris.pregen-remaining
- Mark generation timings unavailable after 10 seconds without generation
- The build resolves VolmLib master-SNAPSHOT when no sibling checkout is substituted
- The native runtime manifest, roots and keep rules come from the embedded natives
- The packed jar natives are verified against the embedded provider shas
- Every jar carries META-INF/volmit/volmlib.properties
- The build logs the resolved VolmLib once
- publishedNativeRuntime, the loader coordinate flags, mavenLocal and publish-volmlib are gone
- 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
- Maintenance ends only when it was entered
- Folia no longer treats a refused chunk requested during evacuation as a chunk system crash
- A chunk is refused while Folia world maintenance forbids mantle stages
- Such chunks no longer end up missing objects, caves, deposits or their REAL flag
- Refused chunks warn at most every 5 seconds
- The overworld mode no longer bypasses mantle stages
- 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
- 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
- The reconciler uses a throwing resolution so a broken world fails without stopping the server
- A failed enable on a server with Iris worlds keeps Iris enabled with a locked runtime
- bukkit.yml bindings in vanilla slots count as Iris worlds for that lock
- The shutdown-based vanilla fallback guard is gone
- A recorded modded bind failure rethrows instead of rebinding on every chunk call
- The first modded bind failure logs a banner
- Persistent-dimension reinject failures log a banner and repeat to operators on join
- Modded logins are refused while the configured primary Iris world is missing
- Startup holds generation admission through recovery and runtime attachment
- Prepared startup state removes the second recovery scan before generator readiness
- Recovery batches allocated chunks by region with reusable snapshot buffers
- Region decoding uses up to four workers within processor and heap limits
- Oversized regions and external chunks use bounded direct reads
- Status parsing validates chunk coordinates without constructing the full NBT tree
- Region snapshots reject changed files, allocation headers and truncated payloads
- Native zlib decompression uses jlibdeflate with a Java inflater fallback
- Chunk readers reuse region handles and decompression buffers during recovery and boundary capture
- Semantic shards reuse validated summaries with invalidation on mutation
- Semantic key validation avoids regular expression allocation
- Saved biome indexes use buffered sequential reads with reusable CRC state
- Pack inspection reads validated manifest and pack state without opening terrain indexes
- Datapack compilation reuses pack inspection within each operation
- Kernel staging avoids duplicate pack hashing when no activation is pending
- Pack copying and directory synchronization use up to four available processors
- Boundary publication batches directory synchronization around durable catalog publication
- Configured world reconciliation reuses ready runtimes after identity and saved-state checks
- Explicit world loads retain the full validation path
- Regression tests cover startup admission, recovery, malformed data, resource limits, publication and reconciliation
- Packages regrouped by domain: generation, world, pack, studio, structure, platform, command, localization, diagnostics
- Forked VolmLib utilities dropped for the shared library: noise, stream, interpolation, hunk, matter
- Engine-coupled stream decorators moved to generation.stream.GenerationStreams
- Hunk section splits now run on the Iris burst pool through HunkBurst
- Artifact entry lists, purity allowlists and shrink rules follow the new paths
- Debug dump replaces the root debugdump command
- Debug toggle controls diagnostic logging
- Debug version uses the shared version display
- Root version remains executable but hidden from help
- Diagnostic dump routing retains its separate permission path
- Translations and tests cover the revised command structure
- 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
