Games now binds guild tables to permanent guild incarnations and captures the character that stakes or deals before money enters play. Another character on the same account cannot collect those stakes, and a deleted guild's namesake cannot claim its bank or tables. Existing guild tables migrate once after faction readiness, with an immutable backup and persisted migration plan.

Guild-bank transfers and citizen tax now use one balanced Denars posting per durable intent. Net winnings and actual withheld whole-chip tax are planned together; only an applied posting authorizes item/float changes. Casino-profit bookkeeping uses the same operation ID. Prepared retries retain their ID; interrupted delivery, partial winnings, missing identity and failed bookkeeping retain a frozen table and review record rather than replaying money or discarding an obligation. Physical item escrow and automatic recovery of ambiguous delivery remain out of scope.

Requires the stage 5 dependency set: DenarEconomy 0.3.0, SimpleFactions 4.0.0 and TLibs 2.4.0. DenarEconomy is now a required plugin dependency. No deployment or release is included.

Validation: tfmc-mvn -o -B --no-transfer-progress clean verify on the CachyOS build worker: 1,155 tests passed, including balanced bank-funded win/tax, refusal, stable retry IDs, restart quarantine, item/storage/profit failures, incarnation migration and character-switch regressions. Existing test and coverage configuration remains enabled.

Coverage: 98.93% lines and 96.05% branches (JaCoCo).

Documentation: TF-Minecraft/Docs#201

📝 Summary

Summary by CodeRabbit

  • New Features
    • Guild-owned tables are now linked to a specific guild identity, preventing access when a guild is replaced.
    • Wager payments and taxes are processed through quoted, recorded transactions, with interrupted or unresolved payouts retained for review.
    • Tables with unsettled funds are protected from resets, pickups and other money operations.
    • Table loading can be deferred, and existing guild tables are migrated while preserving backups.
  • Changes
    • DenarEconomy is now required to run the plugin.

Walkthrough

The change adds guild-incarnation and player-character identity tracking, plans wager movements before applying them, and records ledger operations in a durable journal. Table loading, session control, tax handling, and settlement now include checks for blocked or unresolved funds.

Changes

Wager identity and lifecycle

Layer / File(s) Summary
Guild incarnation and table migration
src/main/java/net/tfminecraft/games/guild/*, src/main/java/net/tfminecraft/games/table/Table.java, src/main/java/net/tfminecraft/games/table/TableHouse.java, src/main/java/net/tfminecraft/games/table/TableManager.java, src/test/java/net/tfminecraft/games/guild/*, src/test/java/net/tfminecraft/games/table/*
Guild table ownership is tied to an incarnation UUID. Table data stores guild and wager-character identities. Loading prepares legacy guild-table migration and avoids loading tables that are already active.
Character-bound transaction planning
src/main/java/net/tfminecraft/games/table/Table.java, src/main/java/net/tfminecraft/games/wager/*, src/test/java/net/tfminecraft/games/support/TestCharacters.java, src/test/java/net/tfminecraft/games/wager/*, src/test/java/net/tfminecraft/games/table/TableManagerChipLayoutTest.java
Account types support planning copies. MoneyTx validates captured player characters and applies strict checks to bank and tax movements. Tax quotes carry the earning character and tax account.
Durable ledger intent handling
src/main/java/net/tfminecraft/games/persistence/DurableFiles.java, src/main/java/net/tfminecraft/games/wager/GuildBank.java, src/main/java/net/tfminecraft/games/wager/WagerJournal.java, src/main/java/net/tfminecraft/games/table/TableManager.java, src/test/java/net/tfminecraft/games/wager/GuildBankTest.java, src/test/java/net/tfminecraft/games/wager/WagerJournalTest.java
Wager operations persist an intent before posting. Applied operations update and save table state before the intent is removed. Guild balances and profit use Denars accounts keyed by guild incarnation.
Table session and settlement safeguards
src/main/java/net/tfminecraft/games/Games.java, src/main/java/net/tfminecraft/games/table/TableManager.java, src/main/java/net/tfminecraft/games/wager/WagerEngine.java, src/main/resources/plugin.yml, pom.xml, src/test/java/net/tfminecraft/games/table/*, src/test/java/net/tfminecraft/games/wager/WagerEngineTest.java
Session, reset, pickup, and settlement paths check blocked money. Payout and tax movements use one quoted transaction. Unresolved or failed guild settlements retain funds and quarantine the table. DenarEconomy is now a required dependency, and startup initialises the journal and schedules deferred loading.

Merge Risk: 🟡 Moderate · up to 4d231

Idle personal tables can become permanently frozen when a dealer who never staked steps down. Saves and wagers may fail on hosts where parent directories cannot be opened. A temporary guild lookup error during migration can permanently remove a guild's table ownership. Resolve these before merging.

Review comments at
@src/main/java/net/tfminecraft/games/guild/GuildTableMigration.java:
- Around line 30-33: Update the migration flow in GuildTableMigration to
distinguish an absent guild from a failed incarnation lookup. Add a GuildTables
lookup variant that reports caught lookup failures separately, and return false
on failure before writing the migrated manifest; preserve null incarnation
handling for genuinely absent guilds.

Review comments at
@src/main/java/net/tfminecraft/games/persistence/DurableFiles.java:
- Line 32: Update the directory synchronisation in DurableFiles.write and delete
to sync only the target’s immediate parent, rather than traversing and syncing
every ancestor. Preserve synchronisation of parents of directories created by
the operation, and continue propagating IOException so durable-persistence
failures still block dependent operations.

Review comments at @src/main/java/net/tfminecraft/games/table/TableManager.java:
- Around line 275-298: Update TableManager.loadTables to remember files that
fail for reasons other than GuildTableMigration.prepare returning false, and
skip those files on subsequent onlyMissing passes. Continue retrying files
deferred by prepare so migration can complete, while preventing permanently
unloadable files from being parsed and logged on every loadDeferred run.

Review comments at @src/main/java/net/tfminecraft/games/wager/MoneyTx.java:
- Around line 192-198: Move the recipient identity check in the leg-planning
flow to after `plan` returns a non-null plan and before the plan is added to
`planned`. This ensures legs with no planned transfer do not quarantine the
table; preserve the existing validation for legs that will move money.

ryanbarlow97 dismissed coderabbitai[bot]’s stale review October 12, 2026 21:30

Adjudicated per thread: three findings were valid and are fixed (c98222c, 7da9e48, c5b8f97) — failed guild lookups no longer stamp migration, zero-money legs no longer quarantine tables, and unloadable table files are not re-reported every 5 seconds. The DurableFiles finding is refuted in-thread (deliberate ancestor-fsync durability boundary). Full clean verify passes (1,161 tests, coverage improved) and CI is green on c5b8f97.
