fix: stop food and pot duplication

[ryanbarlow97]

Summary

Critical: carved roasts and sausage chains became whole again when a chest was opened

ConversionManager.onOpen replaces each food with a clone of the first "equal" food in the chest or player inventory, so the two stack. InventoryAdder.equalsFood only compares category, id, origin, quality and tag steps. It ignores:

• carve state
• base food and nutrition overrides
• cook time
• lineage
• catch size

For example, a player could carve a Beef Roast down to 2 cuts on a meat hook and take it back. Opening any chest, with a whole roast in a later slot, then copied the whole roast over it (8 cuts). Repeating that gave unlimited steaks. Sausage chains and high-genetics slaughter roasts worked the same way.

Fix: the clone happens only when ConversionManager.sameApartFromAging says the two stacks are the same once aging is set aside. That means ignoring the clock (LAST_UPDATE, AGE_REMAINDER), the progress within each tag step (TAGS), and the lore written from them.

Critical: pot ingredients duplicated after a chunk reload

CookingManager and CraftingManager cache a station by the furniture's entity UUID. InteractibleFurniture replaces the furniture object with a new one, under the same UUID, when its chunk reloads, and the cache kept the old one. A player could then:

1. take the ingredient, which came from the stale object;
2. break the pot, whose live furniture still dropped that ingredient.

That gave one extra item per reload. The soup variant was worse: all five mashed ingredients came back as well as the three scoops.

Fix: a cached station whose furniture isn't the live object is rebuilt from the live one. Stations are also dropped when their chunk unloads (StationChunks), so stale ones stop ticking. Pot state is saved on the furniture itself (soup servings and extras), so a rebuild keeps it. Only the pot's in-memory temperature resets, as it does after a restart.

Small leaks

• Mixing bowl and frying pan: when a held ingredient needed converting first, setItemInMainHand(converted) stored a copy. The -1 then went to that copy, so the held stack never went down. Both now take from the hand again, as TroughHandler already did.
• Sausage maker: casing paper was checked when the crank started but taken when it finished (6 ticks later). A player could switch it away in between and keep the paper. The paper is now checked again before the chain is made.
• Drinking cups: the empty cup replaced whatever was held a tick after drinking. So switching slots left the glass bottle and added a cup, or overwrote the newly held item. Now only the glass bottle in the slot the cup was drunk from is replaced, and only if it is still there.

Tests

• mvn clean verify passes locally (245 tests).
• FoodStackMergeTest checks that only differences in aging merge, and that a carved roast, a base-food override, a catch size or a different item doesn't.
• StationChunksTest checks which furniture counts as inside an unloading chunk.
• EmptyCupReturnTest covers four cases: the cup goes back in the slot drunk from, switching slots keeps the new item, a bottle moved away gets no extra cup, a slot left empty gets no cup, and the off-hand works.
• Adds MockBukkit 4.95.0 and Mockito 5.20.0 as test dependencies, with the JUnit BOM pinned to 5.10.2, as Thievery does.
• Development build on this pull request succeeds.

Not in this PR

Two other audit findings aren't duplication, so they're left for later:

• CustomCrops harvest quality can be put onto produce that didn't come from the crop.
• Tamed wild babies mature straight away.

Summary by CodeRabbit

• Bug Fixes
  • Empty cups now return to the slot where the drink was consumed, without overwriting another item or the player’s newly selected item.
  • Food stacks merge only when their differences are limited to aging information; other item differences prevent merging.
  • Cooking and crafting stations refresh correctly when their chunks unload or their furniture changes.
  • Ingredient handling uses the item in the player’s hand after conversion.
  • Sausage crafting stops if the player is offline or casing paper is missing.

📝 Walkthrough

Walkthrough

The changes update empty-cup replacement, food-stack comparison, station cleanup on chunk unload, converted-item handling, and sausage crafting checks. They also add test dependencies and MockBukkit tests for cup replacement, food comparison, and chunk matching.

Changes

Empty cup replacement

Layer / File(s)	Summary
Targeted cup replacement pom.xml, src/main/java/net/tfminecraft/cooking/cup/DrinkConsumeListener.java, src/test/java/net/tfminecraft/cooking/cup/EmptyCupReturnTest.java	The listener targets the consumed hand slot and replaces its contents only when that slot still contains a glass bottle. Tests cover main-hand and offhand replacement, slot changes, and non-bottle contents. Test-scoped MockBukkit and Mockito dependencies are added, along with JUnit BOM management.

Food stack comparison

Layer / File(s)	Summary
Compare food apart from aging src/main/java/net/tfminecraft/cooking/manager/ConversionManager.java, src/test/java/net/tfminecraft/cooking/manager/FoodStackMergeTest.java	Food stacks must match after aging-related data is removed. Tests cover aging differences and differences in other item data.

Station chunk lifecycle

Layer / File(s)	Summary
Identify stations by chunk src/main/java/net/tfminecraft/cooking/utils/StationChunks.java, src/test/java/net/tfminecraft/cooking/utils/StationChunksTest.java	The utility checks furniture location, world, and chunk coordinates. Tests cover chunk boundaries, other worlds, and null locations.
Unload and refresh station references src/main/java/net/tfminecraft/cooking/manager/CookingManager.java, src/main/java/net/tfminecraft/cooking/manager/CraftingManager.java	Both managers remove stations in an unloading chunk. They reuse cached references only when the furniture object is identical.

Converted hand items

Layer / File(s)	Summary
Use the inventory-held converted item src/main/java/net/tfminecraft/cooking/cooking/FryingReference.java, src/main/java/net/tfminecraft/cooking/mixing/MixingBowlHandler.java	After conversion, both handlers retrieve the item from the player’s main hand before continuing.

Sausage crafting checks

Layer / File(s)	Summary
Validate crank completion src/main/java/net/tfminecraft/cooking/sausagemaker/SausageMakerHandler.java	Crafting stops if the player is offline or no casing paper is held after the meat-slot check.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 1a85e

An inventory-open merge can discard non-aging food lore; resolve this data-preservation risk before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 1a85e

The changes narrow known item-duplication paths, but station recovery and food replacement affect persistent player assets. The available evidence does not fully establish their behavior across interrupted or repeated lifecycle transitions.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The relevant attacker-controlled actions are player consumption, inventory opening, and station interaction or chunk lifecycle. The observed mutations concern player items and furniture-held ingredients; the inspected paths do not show a new cross-service authority or privilege boundary.

Trust Boundaries and Controls

• observed — The delayed cup replacement is confined to the consuming player's captured slot and checks for a glass bottle before writing. It does not prove the bottle is the originally consumed one, but the prior replacement also relied on a bottle check and searched more broadly.

Resilience and Maintainability Implications

• inferred — Eviction stops cached cooking references from ticking after their chunk unloads, while delayed load handlers attempt reconstruction. The inspected code does not establish ordering or durability guarantees for an interrupted unload, repeated load, or break before reconstruction.

Hardening Proposals

• proposed — Exercise add, take, break, unload, reload, and repeat transitions against persisted furniture state, checking that each ingredient has one authoritative owner and that interrupted or delayed reconstruction cannot create a second claim to it.

35-80: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Cover the DrinkConsumeListener.onDrink slot mapping.

EmptyCupReturnTest calls replaceWithEmptyCup directly with hard-coded slots. These tests do not exercise the registered PlayerItemConsumeEvent handler, its EquipmentSlot mapping, or its scheduled task. A regression that passes the wrong slot can therefore pass every test and leave the consumed bottle without an empty-cup replacement. Add handler-level tests for main-hand slot capture and off-hand mapping.
