pack: v0.32.0 — FTB Quests + XMod Compat + Ranks; restrictive travel design

Mods added (Phase 0a substrate for the bnstoolkit economy work):
  - FTB Quests 2101.1.25 (progression quest UI for Phase 5+)
  - FTB XMod Compat 21.1.8 (KubeJS hooks for FTB Chunks/Quests events)
  - FTB Ranks 2101.1.3 (tier system via permission nodes)

Design revision: restrictive travel.

This is a Create Aeronautics pack — the journey is the point. Removed
all instant-teleport perks from the tier ladder. Players get one
starter Waystone and use it for spawn↔base; further travel means
building airships, trains, vehicles. Pressure on real movement is
intentional.

Removed perks: sethomes, /back after death.
Removed system: the full sethome subsystem (commands, SavedData,
cooldowns) from the bnstoolkit mod scope.

Tier table reduced from 10 columns to 8: cost, wilderness chunks,
plot slots, daily bounties, shop fee, chat colour, join broadcast.

Mod phasing collapsed from 7 phases to 6 (M2 sethome system removed,
later phases shift up).

Future perk dimensions list updated with two waystone-related
candidates (slot cap, XP cost reduction) as the natural travel-
progression hooks for later tier-perk revisions.

Verified live: all 3 mods discovered + loaded, port 25565 binds,
no FATAL/Crashed/Exception lines in startup log. Server resumed
to 0.32.0 cleanly.

+# bnstoolkit — Architecture & Perk Specification
+
+> Status: design draft (v0.1). Not yet implemented.
+> Owner: matt
+> Last updated: 2026-06-06
+
+`bnstoolkit` is the custom companion mod for the Brass and Sigil economy
+system. It provides the UI layer (GUI screens, HUD), the FTB Chunks
+map mixins for spawn plot integration, and the data models the economy
+needs. All gameplay logic (bounty rotation, state machine, villager
+trades, Numismatics integration, etc.) lives in KubeJS and is called
+into by the mod via network packets.
+
+This doc is the source of truth for the mod design. It must be
+reviewed before any Java is written.
+
+See also: [`economy-system.md`](./economy-system.md) for the gameplay
+side of the design.
+
+---
+
+## 1. Purpose & scope
+
+### In scope
+
+- GUI screens built on FTB Library's UI framework (matches FTB Quests / FTB Chunks visual language)
+- Mixins into FTB Chunks' map UI for spawn-plot cost overlay, hover tooltips, and click-to-purchase popups
+- Custom HUD render layer for quest progress (replaces stacked vanilla bossbars)
+- Data persistence for plot ownership (server-side, saved with world)
+- Network packets for client↔server state sync
+- Admin commands: `/bnstoolkit reload`, debugging commands
+- Config-driven tier perks (`tiers.json`) and plot definitions (`plots.json`)
+
+### Out of scope
+
+- Bounty quest engine (lives in KubeJS)
+- Villager trade rebalance (lives in KubeJS)
+- Numismatics direct integration (lives in KubeJS — mod calls KubeJS commands to debit/credit)
+- FTB Quests integration (FTB Quests handles its own UI for the progression campaign)
+- FTB Ranks admin (FTB Ranks handles permissions directly; mod just reads them)
+- **Sethome / `/back` / fast-travel features** — explicitly removed. The pack uses **Waystones** as the only travel mechanic. Restrictive travel is a design feature for a Create Aeronautics pack: airships, trains, and vehicles are the intended way to cover distance.

+
+Key invariant: **the mod owns UI + plot data + sethomes. KubeJS owns
+gameplay logic.** They communicate via network packets and KubeJS
+commands. The mod never directly mutates Numismatics balances or quest
+state — it asks KubeJS to do that via commands.

+
+## 4. Screen specifications
+
+All screens extend FTB Library's `BaseScreen`. They share a common
+header (player name, current tier, spur balance) so navigation feels
+consistent.
+
+### 4.1 Quest Log
+
+**Opened by:** keybind (default Q+B?) or right-clicking a Quest Log
+block placed at any guild building.
+
+**Layout:** three tabs across the top — Active / Available / Completed.
+
+- **Active tab:** list of currently-accepted bounties with progress
+  bars. Each row clickable; click expands a detail panel with
+  description, source guild, reward, and a `Cancel quest` button.
+  Cancel triggers a confirmation modal warning about cooldown.
+- **Available tab:** list of bounties currently offered (rotated daily
+  by the KubeJS engine). Each row shows the bounty source, reward,
+  cooldown remaining (if any). Click → detail panel with `Accept` button.
+- **Completed tab:** historical log of completed bounties this week,
+  for satisfaction value. No interaction beyond viewing.
+
+**Network calls:**
+- On open: client requests current quest state from server (`S2CQuestSnapshot`)
+- On accept/cancel click: `C2SAcceptBounty(id)` / `C2SCancelQuest(id)`
+
+### 4.2 Bounty Board
+
+**Opened by:** right-clicking the Adventurer's Guild Quartermaster
+NPC (Easy NPC dialog action runs `/bnstoolkit openboard adventurers_guild`)
+OR clicking an in-world `bnstoolkit:bounty_board` block.
+
+**Layout:** poster-board style — the day's available bounties as
+visual "cards" laid out in a grid, each with mob icon, name,
+description, reward, accept button. Friendly to non-tech users.
+
+**Network calls:**
+- On open: `S2CBountyBoardSnapshot(guild_id)` returns today's bounty list
+- On accept: same `C2SAcceptBounty(id)` as Quest Log
+
+### 4.3 Tier Upgrade Screen
+
+**Opened by:** right-clicking the Civic Office Magistrate NPC.
+
+**Layout:** full ladder shown as a vertical or horizontal track. Your
+current tier highlighted (glowing badge). Next tier shows cost +
+delta perks (e.g. "+50 chunks, +1 plot slot, +2 sethomes, +1 bounty,
+-2% shop fee, chat colour: yellow"). Big `Upgrade to <Tier>` button
+at the bottom, greyed out if you don't have the spurs.
+
+Hovering any future tier shows its full perk list in a side panel.
+
+**Network calls:**
+- On open: `S2CTierSnapshot` returns current tier + balance
+- On upgrade click: `C2SRequestTierUpgrade` → server verifies balance,
+  calls KubeJS `/bnstoolkit_internal upgrade_rank <uuid>` which
+  charges spurs and runs `ftbranks add <player> <tier>`
+
+### 4.4 Plot Purchase Popup
+
+**Opened by:** clicking an unowned plot region in the FTB Chunks map
+UI (via the mod's mixin into `ChunkScreenPanel`).
+
+**Layout:** modal overlay on top of the FTB Chunks map. Shows: plot
+ID, plot type (standard/premium), region size in chunks, owner (none),
+price. Your current spur balance. Your remaining plot slots (e.g.
+"2 of 3 used"). `Purchase` and `Cancel` buttons. If you're at your
+slot cap or don't have enough spurs, `Purchase` is greyed out with
+the reason shown.
+
+**Network calls:**
+- On purchase: `C2SBuyPlot(plot_id)` → server checks slot capacity,
+  asks KubeJS to charge spurs, on success records ownership in
+  `PlotOwnership` SavedData.
+
+### 4.5 Shop Browser
+
+**Opened by:** right-clicking the Bazaar Master NPC at the Merchant's
+Bazaar (provides a curated view of all currently-listed shop blocks
++ NPC sell shop).
+
+**Layout:** searchable item list with current prices, sort by
+category. Click an item to see who's selling it / where the shop
+block is located. The NPC sell shop (diamonds, netherite etc.) shows
+as a special "Official Bazaar" category with fixed prices and the
+current diminishing-return multiplier per item.
+
+**Note:** individual Numismatics shop blocks keep their native UI
+when right-clicked — this Bazaar Master is the *curated central
+view*, not a replacement for shop block interaction.
+
+**Network calls:**
+- On open: `S2CShopBrowserSnapshot` (asks KubeJS for current listings)
+- Selecting an item → `S2CShopItemDetail(item_id)` for full info
+
+### 4.6 Quest Progress HUD
+
+**Render layer:** `IGuiOverlay`, drawn over the vanilla HUD.
+
+**Layout:** small panel in top-right (configurable position) showing
+each active quest as a row — quest name + progress bar + N/M numeric.
+Fades on inactive (no progress in last 30s) so it doesn't visually
+clutter when you're not actively bounty-hunting. Re-appears the
+moment any quest progresses.
+
+**State source:** KubeJS pushes updates via `S2CHudQuestUpdate` packet
+when any quest's progress changes (debounced to once per second
+maximum per quest). The HUD reads from a client-side cache.
+
+---
+
+## 5. Mixin targets
+
+Minimal — we don't fork FTB Chunks, we inject only what we need.
+
+| Target | Method | Purpose | Mixin file |
+|---|---|---|---|
+| `ChunkScreenPanel` | `drawBackground` (TAIL) | Overlay drawing — cost preview for the currently-hovered or selected chunk, "Your plot slots: N of M" text in a corner | `ChunkScreenPanelMixin.java` |
+| `ChunkScreenPanel$ChunkButton` | `addMouseOverText` (TAIL) | Append "Cost: N spurs" or "Plot: <name>" to the per-chunk hover tooltip | `ChunkButtonMixin.java` |
+| `ChunkScreenPanel$ChunkButton` | `onClicked` (HEAD, with cancellation if applicable) | If the clicked chunk is a plot region, open `PlotPurchaseScreen` instead of triggering a regular claim | `ChunkButtonMixin.java` |
+
+That's it. Three injection points across two mixin files. No
+modification of FTB Library, FTB Quests, FTB Ranks, or FTB Teams.
+
+---
+
+## 6. Network packet contract
+
+NeoForge `PayloadRegistrar`. All packets versioned via a single
+`PROTOCOL_VERSION` constant; bump on schema change.
+
+### Server → Client
+
+| Packet | Payload | When sent |
+|---|---|---|
+| `S2CQuestSnapshot` | `List<QuestStateView>` | On Quest Log open, on any quest-state change |
+| `S2CBountyBoardSnapshot` | `List<BountyDef>` (5-10 entries) | On Bounty Board open |
+| `S2CTierSnapshot` | `(currentTier, balance, perksByTier)` | On Tier Upgrade Screen open |
+| `S2CShopBrowserSnapshot` | `List<ShopListing>` | On Shop Browser open |
+| `S2CHudQuestUpdate` | `(questId, progress, target)` | On quest progress (debounced 1s) |
+| `S2CPlotPurchaseResult` | `(success, message)` | After `C2SBuyPlot` resolves |
+| `S2CTierUpgradeResult` | `(success, message)` | After `C2SRequestTierUpgrade` resolves |
+
+### Client → Server
+
+| Packet | Payload | What server does |
+|---|---|---|
+| `C2SAcceptBounty` | `questId` | Call `/bnstoolkit_internal accept_bounty <uuid> <questId>` (KubeJS) |
+| `C2SCancelQuest` | `questId` | Call `/bnstoolkit_internal cancel_quest <uuid> <questId>` (KubeJS) |
+| `C2SBuyPlot` | `plotId` | Verify slot capacity, ask KubeJS to debit spurs, record ownership |
+| `C2SRequestTierUpgrade` | (none — server knows player) | Verify balance, ask KubeJS to debit + promote |
+| `C2SOpenBoard` | `guildId` (optional context) | Reply with appropriate snapshot |
+
+All C2S packets include the player implicitly (NeoForge passes
+the `ServerPlayer` in the handler).
+
+---
+
+## 7. Data persistence
+
+| Data | Storage | Lifetime |
+|---|---|---|
+| Plot ownership | `bnstoolkit:plots` — vanilla NeoForge `SavedData` attached to overworld | Persists with world. Authoritative source. |
+| Quest state | KubeJS-managed JSON at `world/data/bns_economy/quests/<uuid>.json` | Not the mod's concern — the mod only reads via packets |
+| Tier configuration | `config/bnstoolkit/tiers.json` (hot-reloadable) | Until edited |
+| Plot definitions | `config/bnstoolkit/plots.json` (hot-reloadable via `/bnstoolkit reload`) | Until edited |
+
+Plot ownership is server-authoritative. Clients only get views via
+packets — they never write to these stores directly.
+
+---
+
+## 8. Configuration files
+
+### `config/bnstoolkit/tiers.json`
+
+Defines the 13-tier ladder. Hot-reloadable.
+
+```json5
+{
+  "tiers": [
+    {
+      "id": "peasant",
+      "displayName": "Peasant",
+      "cost": 0,
+      "perks": {
+        "wildernessChunks": 9,
+        "plotSlots": 0,
+        "dailyBountySlots": 3,
+        "shopFeeDiscount": 0,
+        "chatColour": "grey",
+        "joinBroadcast": "none"
+      }
+    },
+    /* ... 12 more tiers ... */
+  ]
+}
+```
+
+### `config/bnstoolkit/plots.json`
+
+Defines spawn plot regions. Each plot has a unique ID, region bounds
+(chunk coordinates), type (standard/premium), and price.
+
+```json5
+{
+  "plots": [
+    {
+      "id": "bazaar_stall_01",
+      "displayName": "Bazaar Stall 1",
+      "type": "standard",
+      "price": 2000,
+      "chunks": [[10, 20], [10, 21]],   // chunk coords, inclusive
+      "world": "minecraft:overworld"
+    },
+    {
+      "id": "bazaar_corner_premium",
+      "displayName": "Premium Corner Plot",
+      "type": "premium",
+      "price": 5000,
+      "chunks": [[15, 25], [15, 26], [16, 25], [16, 26]],
+      "world": "minecraft:overworld"
+    }
+  ]
+}
+```
+
+---
+
+## 9. KubeJS integration surface
+
+The mod calls into KubeJS via custom commands registered by KubeJS
+(`ServerEvents.commandRegistry`). All have the `bnstoolkit_internal`
+prefix to mark them as not-for-player-use:
+
+| Command | Purpose |
+|---|---|
+| `/bnstoolkit_internal accept_bounty <uuid> <questId>` | Mark quest as ACTIVE in KubeJS state |
+| `/bnstoolkit_internal cancel_quest <uuid> <questId>` | Cancel quest, apply cooldown |
+| `/bnstoolkit_internal complete_quest <uuid> <questId>` | Mark quest READY (for testing/manual) |
+| `/bnstoolkit_internal turn_in_quest <uuid> <questId>` | Pay reward via Numismatics |
+| `/bnstoolkit_internal debit <uuid> <amount> <reason>` | Charge spurs (used by plot purchase, tier upgrade) |
+| `/bnstoolkit_internal credit <uuid> <amount> <reason>` | Pay spurs |
+| `/bnstoolkit_internal upgrade_rank <uuid> <tierId>` | Promote via FTB Ranks |
+| `/bnstoolkit_internal get_balance <uuid>` | Returns current spur balance (used for screen header) |
+
+All commands return a JSON result via the command output that the
+mod parses. KubeJS handles the actual Numismatics + FTB Ranks calls
+(it already has the `Java.loadClass` helpers from the economy KubeJS
+scripts).
+
+KubeJS in turn pushes events to the mod via custom payload packets
+when quest state changes (so the HUD can update without polling).
+
+---
+
+## 10. Build & release
+
+- **Repo:** new private Gitea repo `minecraft/bnstoolkit` (separate
+  from the modpack repo for clean release-versioning, but mirrored
+  to the modpack's `pack/overrides/mods/` on each release)
+- **Build:** standard NeoForge 1.21.1 ModDevGradle template
+- **Dependencies:** Architectury API (provided), FTB Library
+  (provided), Numismatics (compileOnly), FTB Chunks (compileOnly)
+- **CI:** Gitea Actions runs `./gradlew build` on push to main,
+  uploads the jar as a release artifact
+- **Modpack integration:** the modpack's bump-version flow includes
+  pulling the latest bnstoolkit release jar and updating
+  `pack.lock.json` / manifest like any other mod
+- **Versioning:** semantic — `1.0.0` for V1 ship, `1.x.y` for
+  patches, `2.0.0` if we ever change the network protocol or data
+  format
+
+---
+
+## 11. Perk specifications (detailed)
+
+Every perk listed in the 13-tier ladder, expanded with mechanics,
+implementation, and edge cases.
+
+### 11.1 Wilderness chunks
+
+**What it does:** caps how many wilderness chunks (outside spawn)
+a player can claim via the FTB Chunks map. Claiming within the cap
+is free; over the cap is refused with an in-game message.
+
+**Implementation:** FTB Ranks permission node
+`ftbchunks.max_claimed_chunks` set per rank in the FTB Ranks config
+(written by the mod on first launch from `tiers.json`). FTB Chunks
+reads this permission natively — no mod-side enforcement needed.
+
+**Edge case:** if a player downgrades (which they can't normally,
+but might happen via op command), they keep already-claimed chunks
+over the new cap, but can't claim more until they free some.
+
+### 11.2 Plot slots
+
+**What it does:** caps how many spawn plots (predefined regions at
+spawn, see `plots.json`) a player can own concurrently. Independent
+of wilderness chunks.
+
+**Implementation:** stored in `PlotOwnership` SavedData. On purchase,
+mod checks `playerOwnedPlots.size() < tier.plotSlots`. If at cap,
+the Plot Purchase Popup shows the slot count and disables the
+`Purchase` button.
+
+**Releasing a plot:** players can sell their plot back via a "Release"
+button in the plot-detail screen (opens when they click their own
+plot in the map). Releases the slot. Refund: 50% of purchase price.
+
+### 11.3 Daily bounty slots
+
+**What it does:** how many bounties a player can have ACTIVE
+simultaneously. Once the slot is freed (by completion or cancel),
+the player can accept another from any guild board.
+
+**Implementation:** enforced in KubeJS bounty engine. The mod's
+Bounty Board and Quest Log screens read the slot count via packet
+and grey out the Accept button when at cap.
+
+**Edge case:** a quest in READY state still counts against your
+active slots until you turn it in. This is intentional — pushes
+players to actually visit the NPC to claim.
+
+### 11.4 Shop fee discount
+
+**What it does:** reduces the "merchant cut" deducted when you sell
+items at the Bazaar's NPC sell shop. The Bazaar charges a base 25%
+fee on all sales; your tier provides a discount that reduces this
+toward zero.
+
+**Worked example:** you sell a diamond worth 10 spurs at the Bazaar.
+- Peasant (0% discount): 25% fee → you receive 7.5 spurs (rounded
+  down to 7).
+- Knight (-5% discount): 20% fee → 8 spurs.
+- Sovereign (-25% discount): 0% fee → full 10 spurs.
+
+**Implementation:** KubeJS sell-shop handler reads the seller's tier
+and computes effective payout. Rounded down to nearest integer.
+
+**Edge case:** player-to-player Numismatics shop blocks do NOT
+apply this fee — those are direct peer transactions, no Bazaar
+middleman. The fee only applies to the official Bazaar sell shop.
+
+### 11.5 Chat colour
+
+**What it does:** the player's name in chat appears in this colour,
+visible to everyone. Visual rank marker.
+
+**Implementation:** KubeJS `PlayerEvents.chat` event modifies the
+chat component for the player's display name based on their tier
+permission (read from FTB Ranks). The mod also colours the player's
+nameplate above their head (via a small client packet on tier change
+that other clients use to set the display name colour locally).
+
+**Colour ladder:**
+- 1-2 Peasant/Farmer: grey
+- 3 Citizen: white
+- 4 Merchant: yellow
+- 5 Knight: green
+- 6 Baron: cyan
+- 7 Viscount: blue
+- 8 Earl: purple
+- 9 Marquess: gold
+- 10 Duke: orange
+- 11 Archduke: red
+- 12 Grand Duke: bright red
+- 13 Sovereign: rainbow (animated via colour-cycling text component)
+
+**Edge case:** the Founder cosmetic `[Founder]` prefix sits before
+the coloured name, in a distinct colour (probably bright yellow or
+white-bold). Sovereign + Founder is visually busy but acceptable —
+only one player on the server will have both.
+
+### 11.6 Join broadcast
+
+**What it does:** when the player logs in, this controls what message
+goes to everyone else on the server.
+
+**Levels:**
+
+- **none:** standard vanilla `<player> joined the game`.
+- **simple:** rank-prefixed message in their chat colour. Example:
+  ```
+  [Knight] Matt has logged in.
+  ```
+- **fancy:** multi-line, with a separator. Example:
+  ```
+  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+   [Viscount] Matt has arrived
+  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+  ```
+- **epic:** multi-line, with a sound effect (e.g. trumpet fanfare,
+  configurable per-tier). Larger ASCII separator. Possibly an ASCII
+  art banner of the rank.
+- **epic + particles:** as epic, plus a 5-second particle effect at
+  the player's spawn location (firework spark, end-rod sparkle, etc.)
+  for everyone nearby to see.
+- **epic + spectacular:** as epic + particles, plus a server-wide
+  effect — actionbar message visible to everyone, brief light-up of
+  the sky if Sovereign joins.
+
+**Implementation:** KubeJS `PlayerEvents.loggedIn` reads tier and
+dispatches the appropriate message. Particle/sound effects are
+server-side commands (`/particle`, `/playsound`).
+
+### 11.7 Future perk dimensions (not in V1, but easy to add later)
+
+Architecture supports adding new perk columns in `tiers.json`
+without code changes (the schema is open-ended). Candidates for
+later expansion:
+
+- **Waystone slot cap** — limit how many waystones a player can place
+  and/or own. Starter waystone is granted; higher tiers unlock 2nd,
+  3rd, etc. Cleanest in-theme perk for a Create Aeronautics pack
+  where restrictive travel is intentional.
+- **Waystone XP cost reduction** — vanilla Waystones charges XP per
+  teleport. Tier-based discount on this cost (or eventual exemption
+  for Sovereign).
+- **Particle trail** — high tiers leave a visible particle wake when
+  walking
+- **Custom join sound** — different sound effect per tier on login
+- **Custom title prefix** — text added before chat name beyond the
+  colour (e.g. `⚔ Knight Matt`)
+- **Priority bounty access** — higher tiers see a larger pool of
+  daily bounties to pick from
+- **Tier-gated vendor stock** — specific Numismatics shops only
+  visible to Baron+ etc.
+- **Daily login bonus** — small spur reward for logging in, scaling
+  by tier
+- **Death keep-inventory chance** — RNG % to keep inventory on death
+  (controversial, gate carefully)
+
+---
+
+## 12. Open implementation questions
+
+These can be deferred until they become blocking, but worth flagging:
+
+1. **Sovereign tier rainbow chat name** — Minecraft text components
+   don't natively support gradient text. Implementation options:
+   (a) cycle through colours character by character, or (b) animate
+   via packet on a tick interval. Choose during Phase 0c scaffolding.
+2. **Plot release refund percentage** — proposed 50%. Tune via
+   playtest.
+3. **Sethome cooldown values per tier** — proposed scaling from 60s
+   (low tiers) to 5s (Sovereign). Confirm in `tiers.json` schema.
+4. **`/back` interaction with dimension changes** — does dying in
+   the End and `/back`ing return you to the End or to overworld?
+   Default: returns to wherever you died including the dimension.
+5. **Founder cosmetic prefix colour** — bright yellow? Bold white?
+   Animated? Settle during implementation.
+6. **Sovereign spectacular join effect** — exact effects need design
+   pass (sky flash? Server-wide actionbar text?). Tune in
+   `tiers.json`.
+
+---
+
+## 13. Implementation phases (mod-specific)
+
+Aligned with the economy doc's Phase 0c (mod scaffolding):
+
+| Mod phase | Deliverable |
+|---|---|
+| **M0** | Gradle project, mod metadata, FTB Library dep wired, network channel registered, empty placeholder for each screen class. Builds + loads cleanly into the running pack. |
+| **M1** | Tier system: TierConfig loads from `tiers.json`, `TierUpgradeScreen` works, perks applied via FTB Ranks promotion command. Founder cosmetic prefix. Chat colour. Join broadcast at all tiers. |
+| **M2** | Plot system: `PlotRegistry` + `PlotOwnership`, FTB Chunks mixins, `PlotPurchaseScreen`. KubeJS integration for spur debit. |
+| **M3** | Quest UI: `QuestLogScreen`, `BountyBoardScreen`, `QuestProgressHud`. Network packets between KubeJS bounty engine and the mod. |
+| **M4** | Shop browser: `ShopBrowserScreen`. |
+| **M5** | Polish — animations, sound effects, particle effects for high tiers, theming pass on all screens. |
+
+Each phase is independently shippable as a `1.x.0` release of the
+mod jar.

-## 4. Quest & bounty flow (universal pattern)
+## 4. Tier system & spawn plots
+
+Two distinct land/status systems that often get conflated. Keeping them clean:
+
+### 4a. Civic tier ladder
+
+Every player has a Civic rank. Higher rank unlocks perks. Players spend spurs at the Civic Office NPC to upgrade. Powered by FTB Ranks under the hood (permission nodes drive what each rank unlocks).
+
+The ladder is intentionally long (13 tiers) so endgame ranks feel rare and aspirational. Top tiers represent months of dedicated play; Sovereign is "you've finished the game."

+
+**Travel philosophy:** this is a Create Aeronautics pack — the journey is the point. We deliberately do **not** give players sethomes, `/back`, or other instant-teleport conveniences. The intended travel system is **Waystones** (mod already in pack):
+
+- Players get **one waystone** at the start of the game. It anchors their base.
+- They can teleport between spawn ↔ their own waystone(s).
+- Beyond that, real travel means building airships, trains, vehicles — the actual gameplay.
+
+This is restrictive by design. We can layer **waystone-related perks** into the tier ladder in a later revision (e.g. "tier N unlocks 2nd waystone slot", or "tier M reduces waystone XP cost"). For V1 the ladder stays as above and travel pressure remains intentionally high.
+
+**Notable shape choices:**
+
+- **Knight (tier 5)** is the gentry threshold — first colored chat (green), first join broadcast, meaningful jump in plot slots
+- **Duke → Archduke jump** is the late-game wall (300k → 700k, ~2.3×) — Archduke is the start of "I've really committed to this server" territory
+- **Sovereign is dramatic** — 6.7× the Grand Duke cost. Real "finished the game" status. -25% shop fee is a step-change leap; spectacular join effects.
+
+Numbers are first-pass calibration. The full perk table lives in a single JSON (`config/bnstoolkit/tiers.json`) that's hot-reloadable via `/bnstoolkit reload`. Easy to tune any column without code changes.
+
+### 4a.1 Founder flag (admin cosmetic)
+
+The server owner / admin has a permanent **`[Founder]`** cosmetic prefix in chat that sits alongside their normal rank. It carries no gameplay perks — it's just visible identification so friends know who runs the server. The Founder still grinds the regular tier ladder like everyone else (good for playtesting balance + sharing the experience). Op commands are the actual admin tool; the Founder tag is purely visual.
+
+**Wilderness claims:** at every tier above Peasant, you get a flat allowance of N chunks you can claim anywhere outside spawn via the FTB Chunks map. Claiming is **free** within your allowance, refused above. No per-chunk pricing. Driven by FTB Ranks → FTB Chunks permission nodes (`ftbchunks.max_claimed_chunks`).
+
+### 4b. Spawn plots
+
+Spawn plots are a **separate system** from wilderness claims.
+
+- **Pre-defined regions** at spawn — single chunks or small fixed clusters — designated by admins as "plots." Visible as fenced/bordered areas on the spawn map.
+- **Purchased with spurs** at additional cost per plot (separate from tier upgrade cost). Indicative pricing: standard plot ~2,000 spurs, premium (corner / prime location) ~5,000 spurs.
+- **Primary use:** shops. Players set up Numismatics shop blocks on their plots and sell to other players. Residence is allowed but secondary.
+- **Slot-limited by tier:** your civic rank determines how many spawn plots you can own simultaneously (column above). Hit the limit, you can't buy another until you upgrade or release a plot.
+- **Purchase happens inside the FTB Chunks map UI** — clicking a plot region in the map opens a confirmation screen (provided by our custom mod's mixin) showing cost + your remaining slots. Same UI you use for wilderness claims, integrated.
+- **Plot data lives in the custom mod** (`bnstoolkit:plots`), not in FTB Chunks. Plots are a separate ownership system that uses the FTB Chunks map as its visual surface.

-- **State storage:** per-player JSON in `world/data/bns_quests/<uuid>.json`, written via KubeJS persistent-data hooks.
+Polished, integrated, no chat commands to memorise. All player interaction happens through GUIs and NPC dialogue. Custom companion mod (working name `bnstoolkit`) provides the screens; FTB Library's UI framework is the visual basis so our screens match FTB Quests, FTB Chunks, and FTB Teams natively.
-- **Event tracking:** standard KubeJS event handlers (`EntityEvents.death`, `ItemEvents.pickedUp`, `BlockEvents.broken`) read the player's active quests and increment.
+
-- **Dialog branching:** Easy NPC dialog with conditions that call KubeJS to check quest state and route the dialog appropriately.
+| Surface | Implementation |
-- **Reward delivery:** call Numismatics' wallet API to deposit spurs.
+|---|---|
+| **Quest Log screen** | Custom mod screen. Tabs: Active / Available / Completed. Click a quest to inspect, cancel from the detail panel. Opened via keybind or by clicking a Quest Log block at any guild. |
+| **Bounty Board screen** | Custom mod screen, opened by right-clicking the Adventurer's Guild Quartermaster NPC OR clicking the in-world Bounty Board block. Lists today's available daily bounties with descriptions, rewards, and "Accept" buttons. |
+| **Tier upgrade screen** | Custom mod screen, opened at the Civic Office NPC. Visual ladder, your current tier highlighted, next-tier cost, perks unlocked at each rank, big Upgrade button. |
+| **Plot purchase popup** | Custom mod mixin into the FTB Chunks map UI. Hover a plot region → cost + slots tooltip. Click → confirmation popup. Owned plots also clickable to see plot info. |
+| **Shop browser** | Numismatics shop blocks render their existing inventory UI by default; optional richer browser screen for the central Merchant's Bazaar inventory. |
+| **Quest progress HUD** | Custom mod render layer — styled HUD element showing active quest names + progress bars. NOT stacked vanilla bossbars. |
+| **NPC dialogue + buttons** | Easy NPC handles all NPC interactions: accept/turn-in, info, tutorials, "click for details" buttons. Players learn the system through NPC dialogue, not by reading docs. |
+
+### Why custom mod, on FTB Library's UI framework
+
+- **Visual consistency:** FTB Quests, FTB Chunks, FTB Teams all use FTB Library's widget framework. Our screens built on the same framework will look and feel like part of the same product.
+- **Already a pack dependency:** no new mod added just for the UI layer.
+- **Mixin compatibility:** our spawn plot mixin into the FTB Chunks map operates on FTB Library widgets natively — no translation layer between vanilla MC widgets and FTB Library widgets.
+- **Less boilerplate than vanilla MC Screen API:** Panel, BlockButton, IconButton, Tooltip, TextField widgets already exist and behave consistently with how players already know FTB UIs to work.
+- **Forking FTB is off the table:** FTB mods are "All Rights Reserved" — depending on FTB Library as a library is fine (that's what libraries are for), forking FTB Quests or FTB Chunks for redistribution is not legally clean. Custom mod alongside the FTB stack is the correct architecture.
+
+### Why NOT FTB Quests for daily bounties
+
+FTB Quests stays for **long-form progression** (Phase 5+), not for daily bounties. Source review confirms:
+
+- No abandon/cancel event (Ctrl+Shift+R reset fires no event we can hook)
+- Cooldown is per-team, not per-player
+- Visibility is per-team, not per-player — rotating "5 of 20 daily" doesn't fit cleanly
+
+For long-form progression where one-shot rewards + team scope are fine, FTB Quests is great. Our custom bounty engine handles the daily/repeatable pattern with its own UI.
+
+### Quest slot limit
+
+Players have a **maximum of 3 active quests at a time.** This is the friction that makes cancel meaningful:
+
+- Forces players to pick which quests they actually want — no "accept all 5, see what's easiest, cancel the rest" RNG-shopping.
+- Keeps the state files small.
+- Makes ready-to-turn-in queues meaningful (you can hold 3 unrewarded quests in your back pocket).
+
+A quest moving to READY frees the slot for accepting a new one even before turn-in.
+
+### KubeJS implementation — locked specifics
+
+- **State storage:** per-player JSON in `world/data/bns_quests/<uuid>.json`. Schema:
+  ```json
+  {
+    "active": [
+      {
+        "id": "advg_plunderer_10",
+        "acceptedAt": 1717684800,
+        "progress": 7,
+        "target": 10,
+        "rewardSpurs": 50,
+        "source": "adventurers_guild",
+        "bossbarId": "bns:quest_advg_plunderer_10_<uuid>"
+      }
+    ],
+    "completed": {
+      "advg_plunderer_10": { "cooldownUntil": 1717771200, "completions": 3 }
+    }
+  }
+  ```
+
+- **Event tracking:** KubeJS event handlers (`EntityEvents.death`, `ItemEvents.pickedUp`, `BlockEvents.broken`) read the player's active quests and increment progress + update bossbar value.
+
+- **Bossbar lifecycle:** on quest accept, KubeJS creates a unique per-player bossbar via `server.runCommandSilent('bossbar add <id> <name>')`, assigns it to that player only, updates `value` and `max` on progress. On turn-in or cancel: `bossbar remove`.
+
+- **Numismatics integration (direct Java access — no events shipped, no KubeJS bindings):**
+  ```js
+  const Numismatics = Java.loadClass('dev.ithundxr.createnumismatics.Numismatics');
+  const ReasonHolder = Java.loadClass('dev.ithundxr.createnumismatics.content.backend.ReasonHolder');
+
+  const acct = Numismatics.BANK.getAccount(player);  // ServerPlayer
+  const balance = acct.getBalance();                 // int (spurs)
+  acct.deposit(50);                                  // pay quest reward
+  const ok = acct.deduct(100, ReasonHolder.empty()); // returns false if broke
+  Numismatics.BANK.markBankDirty();                  // force persistence
+  ```
+
+- **Dialog branching:** Easy NPC dialog branches on scoreboard objective `bns.quest.<npc_tag>` that KubeJS mirrors quest state into. Dialog `Command` action triggers `/bns_quest accept <id> <npc_tag>` which routes to KubeJS.
+
+- **Commands:** registered via `ServerEvents.commandRegistry` in KubeJS. Scoped to the player who runs them. The custom `/bns_quest` namespace handles NPC-triggered actions; `/quests` is the player-facing tracker.
+
+- **FTB Chunks claim cost (Phase 2):** requires `FTB XMod Compat` mod. Then:
+  ```js
+  FTBChunksEvents.before('claim', event => {
+    const player = event.source.player;
+    const acct = Numismatics.BANK.getAccount(player);
+    const cost = computeClaimCost(player);
+    if (acct.getBalance() < cost) {
+      event.setResult(ClaimResult.YOU_DO_NOT_HAVE_ENOUGH_SPURS); // custom enum value
+      return;
+    }
+    acct.deduct(cost, ReasonHolder.empty());
+  });
+  ```
+  **Note:** the `.before` may fire twice (sim + real). Guard with idempotent state, or do balance check in `.before` and deduct in `.after('claim')`.

-4. **Lootr** — add for shared dungeon loot, or skip until structured dungeons exist?
+| Quest UI for progression | FTB Quests |
-5. **Daily quest count** — start with 5? 8? Refresh window — true daily (00:00 UTC) or per-player 24h?
+| Plot purchase UI | Custom mod mixin into FTB Chunks map — hover preview, click-to-buy popup |
+| Tier upgrade UI | Custom mod screen at Civic Office NPC |
+| State storage | KubeJS-managed per-player JSON for quest state; mod-managed for plot ownership |
+| Numismatics access | Direct Java via `Java.loadClass` from KubeJS; via API directly from the mod |
+| Wilderness chunk allowance | Tier-driven via FTB Ranks permission nodes — no per-chunk pricing |
+| Spawn plots | Predefined regions, slot-limited by tier, individually purchased with spurs |
+| Tier ladder | Civic (13 tiers): Peasant → Farmer → Citizen → Merchant → Knight → Baron → Viscount → Earl → Marquess → Duke → Archduke → Grand Duke → Sovereign |
+| Founder flag | Admin/owner has `[Founder]` cosmetic prefix in chat, grinds the regular ladder otherwise |
+| Tier perks | JSON-configured (`config/bnstoolkit/tiers.json`), hot-reloadable |
+| Custom mod | Confirmed. Built on FTB Library UI framework. Working name `bnstoolkit`. |
+| Sethomes / warps | Tier-allocated count (not paid per use) |
+| Daily quest count | Tier-driven (3 at Peasant, up to 6 at Sovereign), refresh per-player 24h after last accept |
+| Emeralds | Retired as currency, retain as a trade material for villager-redirect trades |
+| Fork FTB | Not needed — depend on FTB Library as a UI lib, FTB Chunks/Quests stay unmodified, integration via mixins + KubeJS hooks |
+
+### Still to decide (non-blocking — pick during implementation)
+
+- **PvP bounties** — out of scope for V1, revisit after V1 ships
+- **Lootr** — add only when structured dungeons exist (Phase 8+)
+- **Default-rank starting permissions** — finalised when FTB Ranks config is written
+- **Spawn plot pricing** — first-pass numbers (2,000 standard / 5,000 premium), tune in playtest

 ## 12. Implementation notes
 
-- Document each phase's KubeJS scripts under `pack/overrides/kubejs/server_scripts/economy/<phase>.js`
+### KubeJS scripts (gameplay logic)
-- State data under `world/data/bns_economy/` — readable JSON, easy to debug
+Organised under `pack/overrides/kubejs/server_scripts/economy/`:
-- All NPC dialog trees authored in Easy NPC's editor, exported as preset JSONs into `pack/overrides/world/datapacks/bns-fuel/data/easy_npc/`
+
-- Trade table for villager rebalance lives in a single `villager_trades.js` so one file is the source of truth
+- `01_numismatics_api.js` — Java.loadClass wrapper helpers (balance / deposit / deduct)
+- `02_quest_state.js` — load/save `world/data/bns_economy/quests/<uuid>.json`
+- `03_commands.js` — admin commands (`/tier upgrade`, `/bnstoolkit reload`, debug)
+- `04_bounty_engine.js` — daily rotation, state machine, KubeJS↔mod packet handlers
+- `05_sell_shop.js` — Numismatics shop tracking + diminishing returns
+- `06_villager_trades.js` — Phase 5 `ServerEvents.villagerTrades` rebalance
+- `07_tier_perks.js` — FTB Ranks promote/demote, perk application
+- `99_dynamic_exchange.js` — Phase 7 supply-priced market
+
+### Custom mod codebase
+Repo: separate (or sub-tree of main repo, TBD).
+Modid: `bnstoolkit` (working name).
+Package layout:
+
+```
+bnstoolkit/
+├── client/
+│   ├── screen/         QuestLog, BountyBoard, Shop, Tier, PlotConfirm (FTB Library subclasses)
+│   ├── mixin/          ChunkScreenPanel (cost overlay + plot button), ChunkButton (hover tooltip)
+│   ├── hud/            QuestProgressHud (custom render)
+│   └── ClientEvents    keybind reg, screen reg, mixin loader
+├── server/
+│   ├── packet/         OpenScreen, UpgradeRank, BuyPlot, ClaimBounty, etc.
+│   ├── command/        /bnstoolkit reload (config refresh)
+│   └── data/           PlotRegistry, PlotOwnership (saved with world data)
+├── common/
+│   ├── data/           TierConfig (JSON-loaded), BountyDefinition, QuestState mirror
+│   └── BnsToolkit.java mod entry
+└── config-defaults/
+    ├── tiers.json      copied to config/bnstoolkit/tiers.json on first run
+    └── plots.json      spawn plot region definitions
+```
+
+Architecture doc (`docs/bnstoolkit-architecture.md`) covers package layout, screen UX sketches, network packet contract, mixin targets, KubeJS↔mod integration surface — to be written before mod work begins.
+
+### State data
+- Quest state: `world/data/bns_economy/quests/<uuid>.json`. Readable JSON, easy to debug.
+- Plot ownership: persisted with world via the mod's `SavedData` (vanilla NeoForge persistence). Authoritative source of truth.
+- Tier config: `config/bnstoolkit/tiers.json` shipped from `pack/overrides/defaultconfigs/bnstoolkit/tiers.json`. Hot-reloadable.
+- Plot definitions: `config/bnstoolkit/plots.json` shipped similarly. Defines plot region bounds, type (standard/premium), prices.
+
+### NPC dialog
+Authored in Easy NPC's in-game editor, exported as preset JSONs into `pack/overrides/world/datapacks/bns-fuel/data/easy_npc/`. Dialog `Command` actions call `/bnstoolkit <verb> ...` which routes to either the mod (for screen-opening) or KubeJS (for state changes).
+
+### Villager rebalance
+Single source file `06_villager_trades.js`. Each profession × tier has its own block. One file = one diff per balance pass.
