Warn players every 5 minutes when their bank can't cover vehicle upkeep

[Drefvelin]

Summary

• Every 5 minutes (the existing timer % 300 tick in FactionManager.time()), each online player whose personal bank balance is below their projected daily vehicle upkeep gets:

  §cYou lack 15.00 denars in your personal bank to pay vehicle maintenance in 3h 12m §7(/deco deposit for the bank, it does not count the pouch)

• The shortfall is the projected upkeep for all personal vehicles, minus the bank balance of the account that the daily charge uses (PlayerBank.resolve). Berthed vehicles are excluded, the same as in the charge.
• The time counts down to the next new day, which is when processDailyUpkeep runs. Minutes round up, like the ledger countdown.

Tests

• VehicleUpkeepServiceTest: warns with the exact text when the bank is short. Stays silent when the bank covers the upkeep and when the player has no vehicles.
• mvn package: 2023 tests, 0 failures.

Summary by CodeRabbit

• New Features
  • Players with vehicles now receive periodic warnings when their bank balance won’t cover upcoming daily upkeep. The notice shows the amount they’re short and the time remaining until the charge, and explains that funds in a pouch don’t count. Players with sufficient bank funds or no vehicle upkeep due won’t receive a warning.

📝 Walkthrough

Walkthrough

Every 300 timer ticks, the timer checks vehicle upkeep bank shortfalls for online players. The service compares projected daily upkeep with bank balances and sends a formatted warning when a balance is insufficient.

Merge Risk: ⚪ Minimal · up to f4faf

The five-minute warning path is wired to the daily upkeep calculation. No actionable issue remains from the supplied evidence; the change is mergeable after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 280b5

The reminders use each player’s own bank account and do not change how upkeep is charged. The added periodic work could affect the shared timer, but its runtime cost has not been established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The scheduled read can cover every online player every 300 ticks, but each warning is addressed to the Player whose name supplied its ownership and bank lookup.

Trust Boundaries and Controls

• inferred — The observed timer call supplies the server’s online-player collection, not a player-selected target. The service uses each supplied Player’s name for both vehicle ownership and bank resolution, so the observed path does not establish a cross-player identity transition.

Resilience and Maintainability Implications

• observed — At the daily rollover, a nonpositive countdown makes the warning method return before per-player lookups; the daily steps follow the warning call in the timer.

Hardening Proposals

• proposed — If vehicle or bank lookups can stall or fail under load, bound or isolate reminder work so a notification cannot impede the shared economy timer.

_{A rabbit checks the bank before the day,
And counts the upkeep due along the way.
A shortfall gets a message, clear and bright,
With hours and minutes left to make things right.
No pouch can fill the bank, the words explain,
Then off hops the rabbit through the rain.}

as `0.00` do not trigger a bank-shortfall message.
