Matt 1b9e35efea pack: v0.31.0 — replace hacks with Item Obliterator
Replace the v0.30.x ad-hoc disable mechanisms (KubeJS server script,
datapack recipe override, KubeJS client-side JEI hide -- which was
broken on this KubeJS build) with a single proper tool:

  - **Item Obliterator 2.3.0** + dep **Necronomicon API 1.6.0**
    Declarative JSON config to remove items from inventories,
    creative tabs, all recipes (including modded custom recipe
    types), villager trades, and JEI. Exactly the missing capability.

Config: pack/overrides/defaultconfigs/item_obliterator.json5
  Blacklists:
    alexsmobs:transmutation_table
    alexsmobs:shattered_dimensional_carver

Removed (no longer needed):
  - pack/overrides/kubejs/server_scripts/disable_alexsmobs_features.js
    (Item Obliterator handles transmutation_table recipe removal
    and right-click cancel automatically)
  - pack/overrides/world/datapacks/bns-fuel/data/alexsmobs/
      capsid_recipes/shattered_dimensional_carver.json
    (Item Obliterator handles modded recipe removal too)

Both items now correctly:
  - Don't appear in JEI search / item list
  - Don't appear in creative tabs
  - Have no working recipe path
  - Can't be right-clicked / used
  - Get scrubbed from inventories on join

The Void Worm boss + regular Dimensional Carver still work --
nothing else in Alex's Mobs is affected.

Verified live: both mods discovered, Necronomicon read our config
file successfully ("File exists, reading config"), Item Obliterator
loaded with the blacklist.

Note: config schema is v2; v1 configs get overwritten by the mod's
default. Always write configVersion: 2.

Brass & Sigil KubeJS scripts

All custom server behaviour lives here. Files in this tree ship via the modpack manifest (see scripts/Build-Pack.ps1kubejs/ is in managedRoots), get synced to both server and client installs, and are loaded by KubeJS on startup.

Conventions

  • Logging prefix: every console line uses [bns/<module>] so server logs can be filtered with journalctl -u brass-sigil-server.service | grep '\[bns/'. Keeps our output separate from mod output.
  • One concern per file. Recipe overhauls live in recipes_<modname>. Block/item policy goes in a <thing>_policy.js. Don't mix recipe removal with event listeners in the same file.
  • Persistent player data keys are prefixed bns to avoid clashing with other mods' use of player.persistentData. Currently used keys:
    • bnsWaystoneCount (int) — see waystones_policy.js
    • bnsWelcomeGranted (bool) — see welcome.js
  • Performance: hot-path event handlers (BlockEvents.placed/broken, PlayerEvents.loggedIn) must stay O(1). Use Set for ID lookups, never Array.includes inside an event handler. Avoid Modrinth/network calls in event handlers — never. No periodic-tick polling unless absolutely necessary.
  • Server commands are registered under the /bns namespace (/bns admin ..., future: /bns plot ...). See bns_admin.js for the registration pattern.

Diagnostics

When something looks wrong in-game, first port of call:

  1. /bns admin info — prints active flags + counts for the running player
  2. /bns admin waystone-count <player> — read stored count
  3. /bns admin reset-welcome <player> — re-trigger the first-join grant
  4. Server log: journalctl -u brass-sigil-server.service -f | grep '\[bns/'
