Poker tables previously displayed blinds without collecting them, accepted stakes out of turn, reset all-in status between streets, and showed only the winning hand in chat. This change collects blinds automatically, enforces the current turn, adds all-in commands and public action messages, and shows every remaining player's hole cards at showdown.

Adds configurable tournaments with Denar entry fees, separate chip stacks, limited rebuys, antes, timed blind levels and host kick/finish commands. Denars remain in the prize ledger until the tournament finishes; shutdown refunds entries and preserves settings.

Fixes blackjack auto-dealer payouts that returned only the stake when large coin denominations could not make the net winnings after tax. Table withdrawals now plan exact, value-preserving change, and bank/mint payout topups use smaller denominations.

Validation: Java 21 mvn clean verify passed all 1,108 tests; GitHub build passed for final commit 397a0f9. The final CI artifact was installed on TFMCDev01 (Paper 1.21.10-130): Games enabled with ProtocolLib and startup reached Done at 21:05:53 UTC. No Games errors were reported. Other plugins have existing startup configuration errors; multiplayer client rendering was not exercised. Regression scenarios cover real table/money flows, all-ins, blind collection, tournament prizes/refunds, taxed regular and natural blackjack wins, refused change transactions, and isolation of invalid saved tournament settings.

Merge Risk: ⚪ Minimal · up to 397a0

The persistence change isolates malformed poker settings without preventing valid tables from loading. No actionable merge-blocking failure is established in the reviewed tournament and wager behavior; the change is ready to merge after normal checks.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 397a0

Tournament commands enforce player identity and host authorization, and shutdown includes entry refunds. However, a started tournament can reach a state with no participants while retaining its entry money, blocking normal entry and completion until separate recovery. The impact is table-local rather than server-wide.

Retained concerns

  • Medium · reliability · inferred: A started tournament has no normal zero-participant terminal transition. Departure removes each registration but retains the entry ledger and started state; after the last departure, new entry and normal finish are refused. This leaves table-owned prize custody dependent on separate administrative recovery. Shutdown and stale-table cleanup provide refund paths, limiting the concern to recovery and availability rather than established permanent loss.
Security review details

Security Blast Radius

  • inferred — The inspected tournament actions affect participant chips and money held by the selected nearby poker table. The zero-participant recovery gap can recur independently at affected tables; its demonstrated scope is their prize custody and availability, not broader server authority.

Trust Boundaries and Controls

  • observed — Production poker routing requires a player sender with games.bet and resolves a nearby poker table. Configure, kick and finish additionally require the table owner UUID, staff permission or games.admin. Entry charges the invoking player's account rather than a player identifier supplied in command arguments.

Resilience and Maintainability Implications

  • observed — Recovery returns ledger value to its recorded owners, but payout accounts fall back to dropping coins at the table when an owner is offline. Thus recovery preserves a value-return path without establishing exclusive offline delivery; this is an existing account behavior used by the new tournament lifecycle, not a demonstrated newly introduced theft path.
