Magnetization

## Fixed

• Fixed large pregenerated worlds freezing or triggering the server watchdog when optional magnetic integrations were enabled.

  • External magnetic emitters now use chunk-local spatial indexing.
  • Unloaded chunks are removed from the index immediately.
  • Field evaluation no longer loads missing chunks.
  • Disabled integrations are not indexed.
  • Only emitters near active targets are processed, with a bounded per-tick budget.

• This resolves the large-world performance problem reported in GitHub issue #7.

  Added

• Added the permission-free /magnetization manual command for replacing a lost Patchouli Field Manual.

  • If the player's inventory is full, the replacement is safely dropped at their feet.
  • Clear errors are shown when Patchouli is missing or its integration is disabled.

• Added independent configuration switches for the Field Manual recipes:

  • Book + Raw Magnetite — enabled by default.
  • Book + Lodestone — enabled by default.
  • Book + Iron Ingot — disabled by default to avoid conflicts with other guide-book recipes.

• Added compat.externalFieldApplicationBudget, defaulting to 256, for controlling the maximum number of optional-mod magnetic emitters applied per level tick.

  Compatibility and upgrades

• Existing Magnetization 1.3.0 worlds and configurations remain supported.

• Missing new configuration values automatically use their defaults.

• Minecraft and required dependency versions are unchanged from 1.3.0.
