Exiting a dungeon now pays the current character's pouch through Denars.earn, including tax in the same posting. Loot is removed only after payment applies. With no active character, a refusal or an unavailable ledger, the player still exits and keeps the loot.

Each conversion saves and fsyncs its operation ID, captured character, gross cents and slot plan before posting. Interrupted intents remain on disk and block further conversions until staff reconcile them, so exit polling cannot issue another payment. Existing-intent retries use the stored ledger result; altered loot is left for review. Minecraft inventory saves remain separate from ledger commits.

Requires DenarEconomy 0.3.0 (TF-Minecraft/DenarEconomy#38) and TLibs 2.4.0. The 0.3.0 artifact is currently a local build, not a release: GitHub dependency installation is expected to fail until the coordinated provider release. Keep this draft with the stage 5 set; do not release it independently.

Validation: tfmc-mvn -o -B --no-transfer-progress clean verify on CachyOS passes all 115 tests and the unchanged 100% instruction, line and branch coverage gates. Tests use real SQLite ledgers and exercise paid, refused, conflicting, unavailable, no-session, repeated-poll, interrupted-posting and changed-inventory paths.

📝 Summary

Summary by CodeRabbit

  • New Features
    • Players can convert eligible loot into money when leaving a dungeon. Conversion records are handled safely across interruptions, helping prevent duplicate payments or lost items.
  • Bug Fixes
    • Loot is retained when a conversion cannot be completed. If a conversion is interrupted after payment, players are warned that staff review is needed before trying another conversion.

Walkthrough

Dungeon-exit loot conversion now records a payment intent before settlement. It removes captured items only after an applied payment and a matching inventory check. The exit flow reports conversion results and requests staff review when settlement throws an exception.

Loot conversion

Layer / File(s) Summary
Plan conversions and prepare test ledger
src/main/java/net/tfminecraft/trialrooms/environment/entrance/LootConversion.java, src/test/java/net/tfminecraft/trialrooms/LootConversionTest.java, src/test/java/net/tfminecraft/trialrooms/TestMoney.java, pom.xml
Planning captures eligible items and the active character, then rounds the total to cents. Tests cover planning outcomes and use a test ledger. The POM updates DenaEconomy and TLibs versions and adds the test-scoped SQLite JDBC dependency.
Persist and settle conversions
src/main/java/net/tfminecraft/trialrooms/environment/entrance/LootConversion.java, src/test/java/net/tfminecraft/trialrooms/LootConversionTest.java
Settlement records a durable intent before payment. It retries stored operations and checks captured inventory slots before removing items after an applied payment. Tests cover retries, interruptions, refused payments, and intent-write failures.
Use conversions on dungeon exit
src/main/java/net/tfminecraft/trialrooms/manager/EntranceManager.java, src/test/java/net/tfminecraft/trialrooms/EntranceManagerTest.java
The exit flow reports successful conversions, reports when loot remains, and requests staff review if settlement throws. Tests check ledger balances, inventory preservation, and recovery after an interrupted credit.

Merge Risk: 🟡 Moderate · up to 62c38

Paid loot could return after a server crash, and staff may lack the item details needed to reconcile a changed inventory. Resolve these persistence gaps before merging.

@src/main/java/net/tfminecraft/trialrooms/environment/entrance/LootConversion.java:
- Around line 74-85: Update the intent’s slot-plan persistence in
LootConversion.settle to store each slot and its complete ItemStack data using
ItemStack.serializeAsBytes() encoded with Base64, rather than Map.toString() or
material and amount alone; retain enough structure for stable deserialisation.
- Around line 82-91: Save the player’s data after clearing the inventory in the
APPLIED path and before deleting the conversion intent. Update the flow around
`player.updateInventory()` so `player.saveData()` persists the change before
`Files.deleteIfExists(intent)`.

Both findings were valid and are fixed in fe08cbf: conversion intents now persist complete item data, and player data is saved before the intent is deleted. Full clean verify (118 tests, coverage gates met) and CI build pass on the new head.
