- Unit test for the 1.21.1 saved-dimension rule: replaced stems keep their saved generator, Iris worlds and new dimensions persist as they run
- The mixin audit test lists the two 1.21.1 persistence mixins as deliberately unaudited
- Classpath scans accept the union filesystem the NeoForge 21.1 test harness mounts and skip test classes merged into it
- The 1.21.1 NeoForge server access test checks the cached world array the tick loop reads
- Mod targets 26.2 and 26.1.2 (inheriting 26.2) with Fabric 0.19.5, Forge 65.1.3 and 64.1.4, NeoForge 26.2.0.89 and 26.1.2.116
- The 26.3 target reads the minecraft26_3 native access rules
- Per-version pack.mcmeta ranges for 26.2 and 26.1.2
- 26.2 and 26.1.2 test overlays and replacements for the pre-26.3 biome, spawn, carver and sign APIs
- NeoForge compiles against the loader's own ASM while the mod jar keeps the bundled ASM
- Mod targets list an ordered overlay chain; later overlays replace earlier ones and earlier source replacements apply to inherited files
- Forge and NeoForge metadata take their loader version range from the target
- The Fabric permissions library is bundled only for targets that declare it
- Dropped the 1.21.1 mods.toml copies that only differed in the loader range
- Merge feature/modded-versions into the modded fix integration
- Take loader pins from gradle/mod-targets.json for every target
- Pin the 26.3 NeoForge target to 26.3.0.83
- Build Fabric, Forge and NeoForge per target listed in gradle/mod-targets.json (1.21.1, 26.3)
- Add 1.21.1 adapter source overlays under adapters/*/src/versions/1.21.1
- Add verifyModdedMatrix and per-target Java runtime verification of loader jars
- Re-inject persistent dimensions from the levels-ready hook before the watchdog starts
- Wait for queued chunks and the final save before pregen completes
- Add the 1.21.1 data version and datapack supported_formats range
- Cascade regions whose sea or shore pool loses every biome
- Use Gson calls available on the 1.21.1 runtime
- /locate biome on non-stacked Iris dimensions searches the visible biomes chunks are filled with instead of falling back to the vanilla structure-biome search
- BiomeSearchFilter rejects columns whose region, land, sea, shore, cave, carving, subterrain or image-map biomes cannot hold a target, so terrain height is computed only for columns that can match
- Hydrology planning state is consulted only when a target comes from a river policy, so a locate no longer queues hydrology tile plans across its whole radius
- Admitted samples resolve inside their generation-history coordinate scope, so saved-biome reads for generated chunks no longer fail the command
- HintedLocator surface hints and IrisBiome visible key enumeration are shared with the locate filter
- Bukkit and modded biome policies share the same filtered search
- Modded create, enable and replace-overworld prepare worlds in the background
- Worlds still being created refuse duplicate create, delete, disable and update
- /iris create, /iris world create, /iris world enable and /iris world replace-overworld acknowledge at once, build the world in the background, and report success or the existing failure messages to the sender when it finishes
- Pack validation, the pack dimension check, generation history creation, pack data loading and the engine build run off the server thread; the server thread only registers the world, creates the level and publishes it
- A second create of a world that is still being created, and delete, disable or update of that world, are refused until it is live
- Server shutdown cancels in-flight creations, waits for an engine that is still building, and rolls back its level and registry entry
- Startup restore and world creation share one dimension injection orchestrator, and abandoning an injection also closes an engine that was already built
- Added the creating-in-background message to every locale file
- Refused /iris replace for dimensions that no level stem defines, including mod levels created while the server starts
- Skipped hand-edited dimensionReplacements entries for such dimensions at startup without moving their data or writing a level stem override
- Derived replaceable dimensions from the recorded worldgen catalog and the applied replacement state
- Recorded a replacement as applied only when the loaded level generates from Iris with the configured pack and seed
- Kept matching Iris generation history without recording it as an applied replacement
- Dropped applied records whose loaded level uses another chunk generator
- Stopped Iris engines bound to replaced levels that a mod swapped out during startup
- Listed installed packs and pack:dimensionKey forms when the replace type is unknown
- Added the refusal and installed-pack messages to every locale
- Modded /iris replace stages vanilla, Iris and mod dimension replacements with Paper syntax
- /iris world takeover removed; replacements live in modded.json dimensionReplacements
- Added /iris replace with override and overwrite aliases on Fabric, Forge, and NeoForge using the Paper target, type, and seed arguments
- Resolved main, nether, end, level-name aliases, iris: and bare names, and any loaded mod dimension as replacement targets
- Kept the saved seed when seed is omitted and stored explicit seeds per replaced dimension
- Applied replaced vanilla and mod dimensions through the forced datapack level stem with the configured seed bound at engine creation
- Applied staged Iris world replacements at startup by moving their terrain aside and repointing the dimension registry
- Refused a second staging while a replacement is pending and checked pack environments for vanilla slots
- Added the modded-only off form to cancel a staged replacement or return a replaced dimension to its own generator
- Reset the Overworld spawn and moved returning players out of unsafe positions after an Overworld replacement
- Renamed the takeover reconciler, model, config key, state file, and recovery folder to replacement names
- Removed /iris world takeover and its help entry and localized messages
- Saved Iris dimensions are prepared in parallel during world load (server-about-to-start on NeoForge and Forge, server-starting on Fabric), before the server watchdog runs
- Server start only creates the restored levels, builds their engines in parallel, and publishes them, so its wait no longer grows one world at a time
- Each restored dimension opens its generation history once instead of twice and resolves its active pack once instead of three times
- An epoch snapshot whose content matches its validated source pack reuses that validation instead of running the full pack validator for every world
- Level creation reads the configured pack and structure biome keys from data warmed during preparation
- Immutable generation packs feed the prepared hydrology cache identity from the data's memoized fingerprint instead of hashing the pack twice per engine build
- Restore logging reports each dimension's preparation and engine time and how long the server thread waited
- /iris worlds and /iris info label each row with its own dimension key instead of the shared generator identity
- Dropped the redundant world= field now that the row label carries the dimension key
- Rows for worlds whose engine has not started use the same dimension key label
- Listing tests assert per-world row labels, including an unstarted engine row
- NeoForge builds compile against NeoForge 26.3.0.83
- The NeoForge mod requires NeoForge 26.3.0.65-beta or newer, the first build without the cached world array
- NeoForge server access test covers publishing, removing and restoring runtime levels against the live level map
- README platform table and bug template name the current NeoForge target
- /iris worlds and /iris info report each Iris world's own seed instead of the server level seed
- /iris worlds and /iris info report the world's persisted generated chunk total instead of the per-session counter
- /iris seed reports the Iris world seed on its World seed line
- Added command tests for per-world seeds, persisted chunk totals and the gamemaster seed gate
- The worldgen catalog (format 2) records the members of every block tag referenced by a captured placed feature, so ore targets using mod block tags convert instead of passing through
- Ore conversion supports noise_based_count and noise_threshold_count placement counts
- Converted ores that produce another converted ore's host block are written ahead of it, so an ore whose host comes from a sibling ore finds that host during the deposit stage
- The modded mixin audit checks that the pack selection mixin keeping the Iris forced datapack last is applied
- Ordering tests cover a world datapack saved after the Iris pack and already-ordered selections
- Mod biomes pick their template across all regions by climate distance, biome category agreement from minecraft and c tags, a reuse penalty that spreads biomes over equally good templates, and the region's overall climate
- Regions much rarer than the dimension's median region are treated as themed and only receive a mod biome when nothing else fits
- Templates derived from void biomes no longer act as climate references
- /iris ingest mods accepts excludeRegions=<a,b> to keep mod biomes out of named regions; unknown region names are refused
- Pack validation rejects borrowedDimensionType on platforms that generate their own Iris dimension type, with an error naming the supported loaders
- Dimension type keys and registry contracts honor borrowedDimensionType only when the platform generation registry supports borrowed types, so Bukkit always derives its generated iris type
- The Bukkit runtime contract always expects the generated Iris type; hotload still refuses a borrowedDimensionType change
- A worldgen catalog capture that fails with any throwable, during the server-thread scan or the background encode, always completes its future and frees the next capture
- Errors are logged with their stacktrace and no longer escape server startup; only virtual machine errors are rethrown after cleanup
- Merged datapack tags keep first-seen value order with duplicates removed instead of re-sorting, so world preset tag order is preserved
- NeoForge remove lists are kept as the deduplicated union of both tags instead of being dropped
- Datapack staging refuses a takeover it cannot stage when the level has applied takeover state or Iris generation history, instead of silently leaving the mod generator in place
- A level's retained generation history now stages its takeover even when the installed pack is gone
- Takeover pack names and dimension keys are resolved to the installed folder and file names before staging, reconciliation, and recording, and the takeover command stores that form
- Reconciliation refuses to switch an applied level to an uninstalled pack before moving any data, and leaves a never-applied level untouched until its pack is installed
- A changed level whose existing Iris generation history already uses the configured pack is recorded as applied instead of quarantined
- New and changed takeovers are recorded only once their level generates from the configured pack; removals are recorded at reconciliation
- A changed takeover keeps its previous applied state until the new pack generates, so a later staging failure still sees the level as taken over
- Failing to write the applied takeover state stops the server instead of only logging
- Retained borrowed-type packs take their pack name from the scoped biome aliases recorded in their generation history instead of the dimension key
- Scoped legacy biome aliases of retained borrowed packs now match the definitions their worlds reference
- A retained pack whose recorded aliases name several packs is refused instead of staged with a guessed name
- Modded config reports unparseable files, non-object takeover sections, and invalid takeover entries instead of returning silent defaults
- Takeover reconciliation refuses startup when takeovers are unreadable and the world has an applied takeover state file
- Config writes are refused while takeovers are unreadable so fallback defaults never overwrite the operator's file
- Staged packs that write the same data/*/tags file now merge into the union of their values
- Tag entries dedupe by value or id and replace stays false unless a contributor set it
- Every non-tag file keeps strict conflict detection
- Rejected target pack names outside letters, digits, underscores and hyphens before ingest starts
- Reported an existing target pack with a translated replace=true hint instead of the raw path
- 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
- Fresh levels adopt generation history with content-addressed biomes instead of legacy aliases
- /iris world takeover <dimension> <pack[:dimension]|off> with help and translations in every locale
- Captured the worldgen catalog after server start, scanning registries on the server thread and encoding and writing on a worker into config/irisworldgen/catalog/worldgen-catalog.json
- Added WorldgenCatalogFingerprint over namespace versions and registry keys
- Added /iris catalog [namespace|refresh] and /iris ingest mods <source> <target> with keyed dimension, namespaces and replace options
- Added catalog messages and help entries for every shipped locale
- Added tests for catalog assembly, namespace summaries, ingest arguments, the registry scan and command registration
- Chest activation and diamond withdrawal stop after ten seconds
- Partial chest evidence records the active phase and window layout
- Folia reports its unavailable reload command without changing pack files
- Gameplay opens normal and copper chests before inspecting loot
- Map markers and saved centers match verified structure targets
- Missing and disabled destinations retain unrelated chest loot
- Storage variants, insertion rollback, region ownership, and resource reloads have runtime assertions
- Separate data packs cover Minecraft 26.2 and 26.3 loot formats
- Container loot finishes on its owning thread before pending markers clear
- Failed fills restore container contents and deferred native loot state
- Failed materialization remains pending without refilling completed containers
- Vanilla tables resolve from the current registry after reload
- Studio loot previews follow the player scheduler
- Tests cover loot rollback, retries, cancellation, and container classification
