Case Closed — v0.7.5-DEV Changelog

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Overview

Three systems land and Cops N Crooks ships as feature-complete. A stationary Trader NPC brings a full buy / barter / sell / tip economy to the street, built on a new shared shop-api framework. A Banker NPC takes deposits, issues withdrawals, and gates a tier ladder that controls your max balance, daily cap, interest, and weekly / monthly loans. And bail finally closes the arrest loop — handcuff → jail → pay-your-way-out (or serve your time and walk).

Alongside those, the release ships a real YAML validation layer, a debug logging block, Vault permissions integration, loot-chest polish, and a wave of command ergonomics (tab-completion fixes, a /gangland alias, optional player targets on bank commands). One feature shipped and was rolled back inside the cycle — see the Ambiguous list.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Configuration Changes

Upgrading from 0.7.4? You'll need to merge in new files and new settings.yml sections — or regenerate them by bumping Config_Version.

New files shipped in this version:

File	Purpose
npc/trader_traits.yml	Trader personality catalogue (mood rates, barter rules, max health).
npc/bank_tiers.yml	Banker tier ladder — balance cap, daily cap, interest, loans per tier.
shop/<shop-key>.yml	One file per shop. Managed through the in-game admin GUIs.

New sections added to settings.yml: Debug (module-level debug logging toggle), a rewritten User.Bank block (rolling-window caps, rename fee), and a new top-level Detainment block with nested Transit, Break_Free, Handcuff_Bribe, Bail, Jail_Bribe, Sentence, and Sounds sub-blocks.

Removed sections: per-account bank knobs that are now tier-scoped (max balance, daily deposit limit, interest rate, death-loss discount, weekly / monthly loan amounts) — they live in bank_tiers.yml instead.

Required YAML validation: every loader now rejects unknown keys and reports a line-accurate error. If you'd been silently carrying dead keys from earlier versions, expect a first-boot warning.

✨ Features

Trader NPCs

A damageable, stationary Citizens NPC that runs a full shop. Placed via an admin command, bound to a shop key and a trait from trader_traits.yml. Right-click opens a buy view; the trader also supports barter (item-for-item swap, no money involved), sell (you hand items to the trader for cash), and tip (spend money to improve the trader's mood toward you).

• Six built-in traits — easygoing, hotheaded, stubborn, generous, shrewd, timid — each with its own mood rates, barter policy, sell-price ratio, and HP. Define your own by adding a new top-level id.
• Per-player mood — mood is a positive-only scalar. Tipping and successful purchases both push mood up; there's no anger / negative track by design. At max mood the trader gives the configured Min_Friend_Discount on buys.
• Barter is a pure item swap — no money ever changes hands on a barter. The trader values incoming items against the category rates set in the shop file and accepts / rejects based on the trait's Barter_Price_Ratio. Turn it off per-trait with Allows_Barter: false.
• Sell — per-category valuation via Sell_Price_Ratio. Players can liquidate loot they don't want; server owners tune how generous each trait is per category.
• Item freshness via decorate, not NBT — newly-delivered shop items are re-decorated on every purchase, so configured lore / display names refresh even if an old YAML shape changed in between.
• Admin editing in-game — no YAML wrestling needed day-to-day. /glw trader edit shop <key> retargets the trader in your crosshair, edit trait <id> changes the personality, edit name opens an anvil to rename (spaces supported), remove deletes the trader you're looking at.
• Trader is damageable by default — Invulnerable: false on the trait makes the NPC killable so you can actually rob a shop. Default traits ship invulnerable; stubborn is the example "killable" trait.
• Persistent repository — traders are saved by the plugin, not by Citizens' saves.yml (SHOULD_SAVE = false at spawn). One source of truth.

New file — trader_traits.yml shape:

New commands:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Shop API Framework

The shop UI, persistence, and transaction logic were extracted into a new gangland-ui/shop-api module so any future shop surface — not just traders — can reuse them.

• Per-shop YAML files under plugins/<plugin>/shop/<key>.yml, scanned on boot and hot-reloaded through the standard /glw reload pipeline.
• Typed transaction returns — PurchaseResult, BarterResult, SellResult replace the old boolean-plus-enum mess. Each carries a clean reason enum plus the outcome payload (item stack delivered, money debited, etc.).
• Shop-level messaging contract — ShopMessageContract and TraderMessageContract route every user-facing string back through the Messages enum, so every shop / trader line is translatable without feature-module imports.
• Admin GUIs — shop definitions, buy entries, sell categories, and per-category barter / sell pricing are all editable in-game. Edits round-trip to YAML via ShopYamlWriter with zero restarts.
• Shop entries deliver per-copy stacks — a buy entry's template.amount is one copy; the BUY AMOUNT picker counts copies, not items. Multi-item copies (e.g. a stack of 5 arrows) are supported.

New admin command:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Inventory & UI Refresh

A new multi-panel inventory framework underpins every revamped GUI this cycle. Panels swap in place without closing the underlying Bukkit inventory, so switching between trader categories, banker sections, and shop-admin pages no longer triggers the familiar close-and-reopen flicker.

• Multi-panel framework — one Bukkit inventory, many logical panels. Each flow (trader, banker, shop admin) registers its panels once and transitions between them with no closeInventory call in between.
• Flow panels for traders and bankers — the trader buy / barter / sell / tip surfaces and the banker deposit / withdraw / tier surfaces now run as flow panels on top of the framework. Rendering logic was rewritten to coalesce updates into a single repaint per click.
• Admin legacy inventory migrated — the legacy admin GUIs were ported onto the multi-panel framework. Panel transitions inside admin flows are now flicker-free, matching the rest of the UI.
• Shift-click + drag-and-drop in admin editors — barter and sell category editors accept shift-click moves and drag operations from the player inventory; previously they only accepted single-click placement.
• Custom inventory filter system — per-view filter controls (search, category sort, etc.) are now first-class, so heavy lists (gang member browsers, shop catalogues) stay navigable.
• Gang inventory revamp — the gang member browser ships with search filters and an updated layout; pagination and rank annotations are easier to scan.
• New inventory layouts — several screens were rebuilt from scratch with consistent borders, panel headers, and decorate pipeline coverage. General icon/glass-pane polish across the board.
• Shop item freshness — car entries now run through a dedicated car item refresher on every delivery, so an updated cars.yml shape is reflected in the next handout. Trader-bought ammunition runs through an AmmunitionItemRefresher so bought stacks merge cleanly with looted ones instead of occupying a separate slot.
• Item-equality by serialized payload — shop, barter and sell comparisons now serialize the full item (NBT + meta), not just Material. Custom-model variants and differently-tagged stacks stay distinct where they used to collide.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Banking & Banker NPC

Every player gets an account balance (cash in hand) and a bank balance. 0.7.5 turns the bank from a cash drop into a full ladder with a dedicated NPC.

• Banker NPC — a stationary Citizens NPC that opens the bank UI on right-click. Create / delete via a command; identical-looking Banker NPCs can be scattered across your map without each one needing its own config.
• Tier ladder — four default tiers (Basic, Premium, Elite, Vault) gate max balance, daily deposit cap, interest rate, death-loss discount, and weekly / monthly loan drops. Every Banker NPC offers the same ladder — there's no per-NPC pricing.
• Rolling-window daily cap — deposits and withdrawals use a rolling window, not midnight, so splitting a transaction across midnight can never count against two separate days.
• Interest — accrued continuously as a fraction of bank balance per 24h, clamped at Max_Balance.
• Weekly / monthly loans — free currency deposited into the bank on a fixed cadence per tier (Weekly_Loan_Amount, Monthly_Loan_Amount).
• Death-loss discount — tier-scoped fraction subtracted from the death-tax deduction (so higher tiers take a smaller hit on death).
• Rename fee — charged from cash every time a player renames their account at a Banker. 0 disables it.
• BigDecimal money handling — price arithmetic on bank operations now uses BigDecimal, so large balances stop suffering from floating-point drift.
• Admin reset — /glw bank resetcap <player|all> wipes the rolling-window cap for one player or everyone.
• Optional player targets on every bank command — /glw bank deposit <amount> [player] / /glw bank withdraw <amount> [player] credit / debit another player's bank as admin actions.

New file — npc/bank_tiers.yml shape:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Bail — Closing the Arrest Loop

Handcuff → jail now has a paid way out. When a player is jailed, the paperwork view exposes a Pay Bail action that charges the player's balance, restores their seized inventory, and releases them.

• Cost scales with wanted level — Bail.Base_Cost + (wanted_level * Bail.Per_Wanted_Level). A one-star arrest pays base; a five-star fugitive pays a lot more.
• Inventory restoration — a successful bail routes through the same ReleasePipeline that a served sentence or admin-release uses, so seized items come back intact.
• Insufficient-funds path — BailResult.INSUFFICIENT_FUNDS is surfaced as a distinct message; no partial charge.
• Handcuff bribe is separate — while handcuffed (pre-jail) you can still bribe the arresting cop; that's Handcuff_Bribe, with its own Base_Cost / Per_Wanted_Level. Bail is post-jail only.
• Jail bribe — a risky shortcut from inside the cell. Pay the cost and roll against Success_Chance; on failure you eat a Fail_Penalty_Seconds sentence extension.
• Sentence — if you pay nothing, serving Base_Seconds + wanted * Per_Wanted_Level_Seconds releases you automatically.

Add to settings.yml:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Loot Chest Polish

Loot chests got a big quality pass.

• Item preview — the chest advertises what it's holding before you open it. No more blind clicks.
• Floating key / lockpick — the required unlock item hovers above the chest as a plain item (no more armor-stand placeholder), so the visual lines up with how the game actually renders custom items.
• Drop chances replace tier requirement — per-table Rarity_Overrides and per-item Drop_Chance buckets (COMMON, UNCOMMON, RARE, EPIC, LEGENDARY) decide what rolls. Tier gating still controls which table a chest draws from; it no longer gates individual items inside a table.
• Natural drops — weapons rolled from a chest now drop as real weapon items (not placeholder renders).
• Hologram drop for weapons — weapon drops float under a hologram showing the weapon's display name.
• Repair system deleted — the loot-chest repair path was removed. If you were relying on it, wire it back through the shop-api sell flow or a custom handler.
• Validation layer — the chest loader now reports malformed entries with a line number instead of silently skipping them.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Civilians

Small but load-bearing.

• Per-type drop chances — civilians now roll their drop table with the same Drop_Chance semantics as loot chests, so a friendly villager and a hostile mercenary don't drop with the same probability.
• Inventory field removed — non-trader civilians no longer carry a Bukkit inventory. Trader behavior moved to the dedicated Trader NPC (above). If your civilians.yml had Inventory: on a type, it's now an unknown key and the new validation layer will flag it — delete the line.
• Stray-entity despawn fix — civilians and cops with no active player were sometimes left alive past the despawn radius. Now cleaned up on the same 3D proximity check.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Weapons & Projectiles Polish

• Flame particle added to incendiary hits — the cone-spray visual is more obviously fire now.
• Natural drops across weapon spawns (hologram + item, not armor stands).
• Weapon drop holograms — dropped weapons float under a name hologram so players can identify loot at a glance.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Commands & Permissions

• New /glw permissions command — list / inspect / grant / revoke permissions directly in-game. Splits cleanly from the rank command.
• Rank permission subcommands split — /glw rank add permission and /glw rank remove permission are now separate subcommands. Tab-completion routes by verb; no more positional confusion.
• Vault permission integration — Vault (soft-dep) is detected and used for permission checks when present. If Vault isn't installed, the built-in permission system handles everything on its own.
• /gangland alias for /glw — both resolve to the same dispatcher.
• Legacy commands revamped — the old flat-args subcommands were rewritten as chained optional-argument nodes, so every positional slot has a tab-completion suggestion list. No more terminal args[n] reads that silently fall through.
• Help commands fixed — the /glw <cat> help <page> surfaces (bank, jail, cop, trader, car, money, civilian, waypoint, rank…) now paginate correctly. Previously some pages rendered blank.
• Tab-completion polish — trailing-space bug fixed, per-argument suggestions align with what actually parses.
• Optional player targets — bank deposit / bank withdraw now accept an optional [player] that admins can target for credit / debit.
• Delete-confirm command fixed — the two-step confirmation flow on destructive commands (gang delete, shop remove, etc.) was resetting its pending state on a race; now stable.
• Custom messages for every command — every user-facing command string now routes through the Messages enum. Previously-hardcoded strings are removed.
• /glw gang members — list the members of a gang from the command line, with paging and the standard rank annotations. Useful for admin inspection without opening the GUI.
• Rank schema + Vault-group rank command fix — the rank command's Vault-group apply path was reading a stale schema, so group changes weren't always propagating to Vault. Rank edits now round-trip cleanly.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

YAML Validation Layer

Every loader in the plugin now runs through a shared validator.

• Unknown-key detection — a key that isn't in the declared schema gets reported with its line number. Catches dead keys left over from upgrades.
• Required-key / missing-node reporting — a missing section still falls back to defaults (same as before) but now logs that the fallback was used, so you can re-add the section on the next edit.
• Depth tracking — nested paths like Cops.Behaviour.Cuff_Radius resolve and validate correctly without custom code in every loader.
• Fallback message loading from the jar — if message/*.yml is missing or corrupt, the loader falls back to the bundled copy inside the jar instead of hard-failing.
• Missing configuration nodes added — the defaults that were loaded silently in prior versions are now explicitly documented in the files so /glw reload reports them accurately.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Debug Logging

Module-level debug logging is now a first-class config surface instead of a JVM-flag dance.

• Debug.Enabled: true + Debug.Modules: [<module>, ...] flips log levels at runtime. Restart the server after editing.
• Valid module names: Gangland, Gangland Core, Gangland Weapons, Cops N Crooks, Inventory API, Lootchest API, Scoreboard API, Sign API, Plugin Persistence, Version Handler. Empty list = every module on the classpath.
• Startup logs demoted to DEBUG — your console is quiet on normal boot. Flip the module list to see the old chatter.
• Logging infrastructure moved to plugin-common — every module's logger setup is now centralized.

Add to settings.yml:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Vehicle Persistence

• Dismount on shutdown — mounted players were being serialized into player.dat as a RootVehicle, which spawned rogue duplicate vehicles on rejoin. PlayerQuitEvent now ejects riders first, and the destroy-all runs in two passes so no entity is left behind.
• Half-block vertical traversal — vehicles now climb slabs and half-blocks smoothly. Previously they caught on the lip.
• Session cleanup ordering — vehicle session save runs before close, not after, so a server restart never loses the last known position.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Internal — Module Reorg & Beans Cleanup

Not user-facing, but flagged here for anyone shipping custom modules against this version.

• Listener and command packages moved inside the bean package for consistency with @ListenerHandler / @CommandHandler.
• Autowire package folded under bean.
• gangland-core main package renamed to me.luckyraven.core.
• BankerViewOpener contract removed — the view is specified directly at the call site, dropping an unnecessary indirection.
• Trader trait loader moved onto the shared bean lifecycle.
• Input interceptors abstracted so anvil-GUI / chat-prompt sessions share the same cancellation pipeline.
• Test suite expanded before shipping (repository lifecycle, cleanup on Windows, HikariCP init).

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Bug Fixes

Trader & Bank

• Users without a bank — newly-created users without a bank row were NPE'ing the Banker view. Now lazy-created on first right-click.
• Trader invulnerable tag — the Invulnerable: false trait wasn't propagating to the Citizens NPC, so "killable" traits weren't actually killable. Fixed by setting both the Citizens protected flag and the Bukkit LivingEntity invulnerable flag at spawn.
• Bargain / tip views dropped — per the trader simplification, bargain and tip-view GUIs were removed and their bug list with them. Tipping is still supported via command / shop integration; the dedicated anvil flow is gone.
• Item moved from inventory into created inventory — a bug where shift-clicking into a newly-opened shop view dropped the item into the wrong slot is fixed.
• Ammunition stacking from trader — bought ammo now runs through AmmunitionItemRefresher and merges with looted stacks instead of occupying a separate slot.
• Shop item equality by Material only — buy / barter / sell comparisons used to match on Material, so custom-model variants and differently-tagged stacks collided. Comparisons now serialize the full item.

Jail & Detainment

• Handcuff → jail → release flow — the release leg occasionally left seized inventory in limbo. Bail, sentence-served, and admin-release now all route through the same ReleasePipeline.

Loot Chests

• Loot chest validation — malformed entries previously crashed or silently skipped; now reported with file + line number.
• Icon swap — the placeholder armor stand used for the "hold-to-open" item was replaced with a proper Bukkit item, so resource packs render it consistently.

Commands

• Delete-confirm command — the two-step confirmation was racing its own state reset.
• Help commands — pages beyond the first weren't rendering for several categories; fixed.
• Tab-completion — trailing-space bug and a mis-ordered suggestion list on some subcommands.

Inventories & UI

• Player heads not rendering in several GUIs — the skull-owner payload was being dropped through the decorate pipeline; preserved now so head icons render correctly.
• Multiple items in the same slot not showing — a paginated-inventory branch was overwriting the displayed stack with whichever item rendered last, hiding everything else assigned to the slot.
• Inventory / multi-inventory interaction bugs — shift-click and drag events on the new panel framework were crossing into the player inventory in a few edge cases. Click handling is now scoped per panel.
• False-positive config report for Multi and Static_Items — the validator was flagging legitimate Multi and Static_Items blocks as unknown keys on /glw reload. Both are now in the declared schema and pass validation.

System & Reliability

• Gang deletion database consistency — deleting a gang now cascades cleanly: members and alliances get orphan-handling passes so stale rows don't accumulate.
• Reload periodical updates — the periodic auto-save and cache cleanup weren't re-registering after /glw reload. Now rebuilt on every reload.
• Stray civilians / cops despawn — NPCs that were out of range weren't always cleaned up.
• Vehicle dismount on shutdown — see the Vehicle section above — mounts were being serialized into the player save file and spawning duplicates on rejoin.
• Language loader — a missing message/*.yml used to hard-fail startup; now falls back to the bundled copy inside the jar.
• Filename typo in prior changelogs — the 0.7.3 / 0.7.4 files shipped with an inconsistent filename casing; standardized.
• Bean ordering race — some beans were being resolved before their graph dependencies had finished initializing. Topological-sort pass hardened.
• Naming-convention sweep — internal file / class names aligned to the project's house convention (Capitalized_Underscore YAML keys, package paths match module names).

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚠️ Possibly Fixes / Ambiguous Changes

Commits whose intent didn't obviously map to either a feature or a fix. Flagged so server owners can spot behavior changes in their own setups.

• "Added a market system" → "Removed the market system" — a player-to-player market / auction-house prototype shipped and was rolled back inside this cycle. It may have left behind gangland-market module traces or stale SQL tables if you ran a development build between those two commits. "Moved economy and bank to gangland-market" is part of the same arc — the economy and bank code briefly lived under gangland-market, then moved back when the market was cut. If you drifted from mainline during the cycle, diff your database schema and module list against the 0.7.5 default.
• "Removed the trade in" — the trade-in variant of the trader sell flow was cut after landing. The remaining sell path is category-based valuation through Sell_Price_Ratio. If you had placeholder text, messages, or admin workflows wired to trade-in, they no longer resolve.
• "Removed Bargin and tip views" — per the trader simplification, the anvil-GUI bargain flow, the dedicated tip view, and the propose-price widget were removed. The trait record dropped from 16 fields to 8. Tipping still works as a currency-spent signal for mood, but there's no standalone tip GUI anymore.
• "Removed the repair system" — the loot-chest repair path went away. If any of your shop templates still reference repair-kit materials, they'll parse as ordinary items.
• "Removed civilian inventory" — non-trader civilians lost their Inventory: field. Existing civilians.yml files with the key will trigger the new unknown-key validator.
• "Changed the default values" — one commit tweaked defaults across loaders without specifying which. If you upgrade by regenerating settings.yml / catalogue files, diff against a backup of your prior version so intentional overrides survive.
• "Removed the banker view opener contract so that you directly specify it" — API surface change for anyone wiring a custom banker view. The view is now specified inline at the call site.
• "Added a bean lifecycle for trader trait loader" — traits now participate in /glw reload. If you had custom code reloading traits manually, remove it — the framework does it for you.
• "Added moving vertically on half blocks or less" — vehicle movement change; watch for slab-heavy parkour tracks behaving differently.
• "Added hologram drop for weapons" — weapon spawns are now accompanied by a floating display name. If you were relying on entity-count-based triggers near weapon drops, you'll see one more entity per drop.
