InventoryAdvancementAccelerator

1. 01

   Per-player item index

   Each player gets an index of item filters, so the trigger checks only the conditions tied to items that changed.

2. 02

   Vanilla predicate matching

   Final evaluation still uses Minecraft's own predicates, so the outcome of each advancement check stays the same.

3. 03

   Correct handling of edge cases

   Counts, tags, data components, slots that turn empty, removed items and cases with several conditions at once are all processed correctly.

4. 04

   Automatic fallback

   When a condition is unrecognized, an async call or resource reload occurs, a Mixin fails to inject, or an internal exception is raised, the mod hands processing back to the vanilla path.

5. 05

   Result verification

   By default the mod compares optimized results with full evaluation, uses the full result on a mismatch and disables the affected index.

Who it’s for: Server owners running NeoForge 1.21.1 dedicated servers with large numbers of advancements or many online players will find the mod relevant. Vanilla clients connect to the server directly, since only the server runs the mod.
