Automated Materials Index (AMI)

1.8.7 - 2026-09-03

Added

• Added a server-side /ami dump (all, items, recipes, loot-tables, trades, worldgen) that works from a dedicated server console. The existing dump tree registers through client command events, which do not exist on a dedicated server, so none of it could be produced headlessly - the one place that loads a full mod set with no GPU, no resource packs and no human clicking. Registered at permission level 2 rather than behind -Dami.debugCommands, because needing a JVM flag on a server you did not launch yourself makes it unusable in exactly the case it exists for. Search nodes, guide docs, the results tree and recipe-viewer dumps are deliberately not included: they read the client index or a viewer plugin and have no meaning without a client.
• Added /ami dump worldgen, writing every biome, structure and dimension with its tags to ami_dumps/worldgen/worldgen-dump.json. This is new data rather than a port: the registry dump has only items. Taking it from the live registry is also the only complete source - modded biomes and structures are datapack JSON and can be scanned from jars, but vanilla's are registered in code, so a data scan silently misses minecraft:deep_ocean and every other vanilla entry.
• Added Fabric and NeoForge /ami dump trades, which resolves the active villager and wandering-trader listing factories against a deterministic server-side sample and writes costs, results, limits, XP, listing classes, and unresolved reasons to ami_dumps/trades/trades_runtime.json. Map-dependent offers can remain unresolved in an isolated world with no discoverable structures.

Changed

• Stack snapshots and CreativeStackVariantExpander.stackIdentityHash no longer read display names or tooltips on a dedicated server. getHoverName() dispatches to Item#getName(ItemStack), which mods routinely override with client code, and the tooltip inputs go through getTooltipLines outright; the existing catch guards stopped those from failing but not from being logged, so a single /ami dump all over a 333-mod pack emitted 6,306 RuntimeDistCleaner errors and spent most of its runtime producing them. Nothing is lost: mod assets/ are never loaded on a dedicated server, so those names only ever resolved to raw translation keys. Server and client identity hashes already disagreed for that reason - exactKey was never comparable across sides and still is not.
• RecipeDumpWriters.writeLootTables gained an overload taking an explicit ResourceManager. The existing no-arg path falls back to Minecraft.getInstance(), and merely executing that branch on a dedicated server trips RuntimeDistCleaner.

Fixed

• Fixed Fabric dedicated servers crashing during AMI startup because FabricPlatformHelper eagerly constructed client key mappings from its common static initializer. Key mappings now initialize only when the client accessor is actually used.
