LumenSmith v0.1.4 — Major Update

---

New Features

In-Game Recipe Creator (/ls create <key>)

• Full click-based GUI recipe builder — no YAML editing needed
• Supports all 9 recipe types: shaped, shapeless, furnace, blasting, smoking, campfire, stonecutting, smithing transform, and adjacent pair
• Click a slot, then click any item in your inventory to assign materials
• Type selector — pick your recipe type visually, change it anytime
• Result amount control — set output amount from 1-64 with +/- buttons (always starts at 1 when picking an item)
• Cooking controls — adjust cooking time (+/-50 ticks) and experience (+/-0.1) directly in the GUI
• Fuel selector — restrict which fuels are allowed for cooking recipes (click to add fuels, right-click to clear)
• Direction option — for adjacent pair recipes, choose horizontal, vertical, or both placement directions
• Auto-generates auto_unlock_on from ingredients
• Saves directly to config.yml and reloads instantly

Recipe Editing

• Edit button in recipe detail view (writable book icon) — loads existing recipe into the creator with all data pre-filled
• Supports editing all recipe types including shaped grid layout, cooking settings, fuel restrictions, and direction
• Saves changes in-place (replaces old config entry)

Recipe Deletion

• Delete button in recipe detail view (TNT icon) — removes recipe from config with one click
• Instantly reloads after deletion

Adjacent Pair Direction

• New direction config field for adjacent pair recipes: horizontal, vertical, or both (default)
• Controls which placement orientations are registered
• Fully configurable from both YAML and the in-game creator

Bug Fixes

Smelting Output Fix

• Fixed critical bug where custom cooking recipe outputs were blocked by remove_by_output
• Example: custom "Crying Obsidian -> Obsidian" recipe was blocked because OBSIDIAN was in the blocked outputs list
• Custom recipes now correctly bypass the vanilla output blocker

Fuel Enforcement Fix

• Switched from FurnaceSmeltEvent to FurnaceBurnEvent for fuel checking
• FurnaceBurnEvent fires before fuel is consumed, making getFuel() reliable
• Prevents infinite smelting loops when wrong fuel was used

Ingredient Display Deduplication

• /ls recipes browser and detail view now groups duplicate ingredients
• Shows STONE x9 instead of listing STONE nine separate times
• Applies to both shapeless and shaped recipe displays

---

Performance Optimizations

O(1) Fuel Index Lookup

• Pre-built cookingFuelIndex map in RecipeLoader (built once during config load)
• CookingBlockListener.onBurn now uses direct map lookup instead of iterating all recipes
• Reduces furnace burn event processing from O(n) to O(1) where n = total recipe count

Memory Leak Prevention

• Creator sessions are now cleaned up on PlayerQuitEvent
• Prevents session map from growing unbounded when players disconnect without closing the GUI

Existing Optimizations

• Pre-computed static messages in BlockCraftListener (no string processing on hot paths)
• Debounced recipe book rescanning with pendingRescan set + 2-tick delay
• boolean[] indexed by Material.ordinal() for O(1) material presence checks in UnlockListener
• Immutable List.copyOf / Map.copyOf for cached recipe data
