Matt c699dcc77b pack: KubeJS tidying + admin commands, bump to 0.20.0
Tidying pass on the KubeJS suite before plot system V1 lands. Sets up
the file structure + conventions + diagnostics so the larger plot
system has a clean foundation.

Changes:

1. NEW kubejs/README.md
   File layout doc + conventions: logging prefix [bns/<module>],
   persistent-data key naming (bns* prefix), one concern per file,
   performance discipline (O(1) lookups, no polling).

2. Split economy_policy.js -> recipes_waystones.js + recipes_numismatics.js
   Single-concern files. recipes_waystones removes ALL waystones
   crafting (welcome.js distributes the only allowed waystone instead).
   recipes_numismatics removes the 5 coin-denomination crafts.

3. NEW kubejs/server_scripts/bns_admin.js
   /bns admin subcommands for OP diagnostics:
     - info                       calling player's flags+counts
     - waystone-count <player>    read stored count
     - waystone-set <player> <n>  override stored count
     - reset-welcome <player>     clear bnsWelcomeGranted -- replays
                                  the welcome grant on next login
   Registered via ServerEvents.commandRegistry with Brigadier tree,
   permission level 2 (OP). No performance cost (operator-triggered only).

4. Logging added to waystones_policy.js + welcome.js
   Every action prints `[bns/<module>] ...` so server logs can be
   filtered with `journalctl ... | grep '\[bns/'`.

Performance discipline applied:
- All event-handler lookups use Set.has (O(1)), not Array.includes
- No periodic tick polling anywhere
- No network calls in event handlers
- console.info is cheap (no string format unless logged)

Bumps to 0.20.0. Plot system V1 follows in v0.21.x as a separate
multi-file submodule under server_scripts/plots/.

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/'
