feat: pay denars to change a locked choice, and reset locks by stage revision - #60
Conversation
Once a stage's lock-time runs out, a configured paid-change rule lets the player reopen it by paying denars (pouch first, then bank). The payment is held while the stage is open: keeping a change counts it and raises the next price, and backing out refunds it. Class is the first rule: free for 5 days, then 100, 1000, and 3000 denars for every change after that. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Merge Risk: 🟡 Moderate · up to Players can be charged when cancelling, have a payment counted against the wrong stage, or open a payable age choice without seeing its price. A revision reload can also carry an old edit into the new price count. Resolve these payment and pricing issues before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to A player’s payment and future prices can be affected by when a stage revision is reloaded or by a class change outside the stage editor. The identified effects are bounded to the affected character, but payment and refund integrity need attention. Retained concerns

Stages take a manual `revision` in stages.yml. When staff raise it after a large change, each character gets a fresh lock-time window on that stage from when it next loads (or at once on reload if online), and paid-change prices start over. New characters start on the current revisions. Also: - Reach DenarEconomy by reflection instead of softdepend. The softdepend made a load cycle (DenarEconomy -> TLibs -> ItemsAdder -> BirdMessenger -> RPCharacters) that stopped the server from starting. - Settle held payments when DenarEconomy disables, since it shuts down before RPCharacters. - Drop edit sessions on quit so the next /rpcharacter edit isn't blocked.

The payment held while a paid stage is open now lives on the character and is saved as soon as the player pays, under "paid-change-pending". A failed refund stays held instead of being dropped, and the player is told it will be retried. When the owner next joins, any hold left by a crash or a failed refund is settled: kept and counted if the character changed, refunded otherwise. Stage revision refreshes also moved to join, so offline data loads can't start a window early. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

@coderabbitai The outside-diff finding (retain pending refunds when the deposit fails) is also fixed in 7fda695. |
DenarEconomy keeps online balances in memory until its own save, so a crash rolls back the withdrawal or refund. Forcing the hold to disk right after paying meant a crash refunded twice: once by DenarEconomy's rollback and again on the next join. The hold now saves with the character on the normal schedule, the same way DenarEconomy saves the balance it changed. Join recovery still retries failed refunds.

What
Adds a general pay to change system. After a stage's
lock-timeruns out, a paid-change rule lets the player reopen that choice by paying denars. Class is the first rule.lock-time: 5d). After that the first change costs 100 denars, the second 1,000, and the third and every one after 3,000. The prices are inconfig.yml./rpcharacter edit, and the payment is held while the stage is open. If they confirm a different class, the payment is kept and the paid-change count goes up. If they cancel, go back, confirm the same class, quit, or the server stops, they get the denars back.Free to change for: 4d 23h/Then: 100 denars, next: 1,000 denarsClick to change for 100 denars/The change after costs 1,000 denars/Refunded if you keep your classKeep your class and get 100 denars back.paid-changes.rules.revision:instages.yml, default 0.
