Matt ffff3bc78d econ: sell shop + bounty engine + player commands + FTB Ranks 13-tier
Foundation economy stack — fully command-driven, ready for the custom
UI mod to layer on top later. Built tonight as a single feature batch.

KubeJS scripts:
  pack/overrides/kubejs/server_scripts/economy/
    00_tier_system.js       — 13-tier ladder + admin commands
    02_sell_shop.js         — /bns sell, 9 items, DR + tier-fee
    03_bounty_engine.js     — /bns bounty, 20 bounties, state machine
    04_player_commands.js   — /bns help, /bns me, /bns tier upgrade

plots.js: updated to support multi-plot ownership based on tier slots
  - plotsOwnedBy() returns list, slot cap from TIER_PLOT_SLOTS table
  - /bns plot release now requires plot id (multiple plots possible)
  - /bns plot mine added

FTB Ranks server config:
  pack/overrides/world/serverconfig/ftbranks/ranks.snbt
  13 ranks with ftbchunks.max_claimed_chunks scaling per tier:
    Peasant 9 -> Sovereign 1500 (chunks)
    Peasant 1 -> Sovereign 200 (force-loaded)
  Name format colour codes match the design doc.

Player command surface (everything callable from chat or Telegram bridge):
  /bns help                          full command listing
  /bns me                            tier, balance, plots, bounties
  /bns tier upgrade                  pay spurs, advance to next tier
  /bns plot list|info|buy|release|mine
  /bns sell list|<item> [count]
  /bns bounty list|active|accept|cancel|turnin|completed
  /bns admin tier get|set|list       (op level 2)
  /bns admin info|waystone-*|reset-welcome  (pre-existing)

Tier upgrade flow:
  1. Player runs /bns tier upgrade
  2. KubeJS takes spurs from inventory
  3. KubeJS sets player.persistentData.bnsTier += 1
  4. KubeJS runs `ftbranks add <player> <rank>` so FTB Ranks applies
     the permission nodes (chunk allowance auto-flips)

Cross-file scope: KubeJS 2101 runs all server_scripts in shared Rhino
global scope. Constants (TIER_CONFIG, COIN_VALUES, bnsTier object,
shared functions like giveCoins/countCoins/takeCoins) are declared
once in their owning file and referenced from siblings. Don't redeclare.

Blocked tonight (deferred):
  - Villager trade rebalance: KubeJS 2101.7.2 doesn't ship a
    villagerTrades event. ServerEvents only exposes command/loaded/
    recipes/registry/tags/tick/unloaded. Verified by grepping the
    KubeJS jar's ServerEvents class. No KubeJS-villager-trade addon
    on Modrinth for NeoForge 1.21.1. Either build into the custom
    mod or add a third-party trade-overrides mod (research pending).
  - Custom mod UI screens: no Java toolchain on host, and these
    need visual iteration with the user anyway.

Verified live: server boots clean, all 4 economy scripts log loaded,
port 25565 binds, no EcmaError or EvaluatorException in KubeJS log.
FTB Ranks reload via rcon confirms "Ranks reloaded from disk!"

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/'
