Houmgaor	2365b63e9c	fix(gacha): validate reward pool before charging currency (#175) ... Filter out gacha entries with no items at the query level (EXISTS subquery) and reorder Play methods to validate the pool before calling transact(), so players are never charged for a misconfigured gacha.	2026-03-10 11:28:11 +01:00
Houmgaor	915e9bc0b0	fix(gacha): prevent panics from misconfigured gacha entries (#175) ... getRandomEntries panics with rand.Intn(0) when box gacha has more rolls than available entries. Fix by clamping rolls, guarding empty entries and zero-weight pools, and fixing an out-of-bounds slice in the receive handler overflow path.	2026-03-10 11:19:22 +01:00
Houmgaor	1e9de7920d	refactor(gacha): extract gacha logic into GachaService ... Move payment processing, reward selection, stepup state management, and box gacha tracking from handlers into a dedicated service layer. Handlers now delegate to GachaService methods and only handle protocol serialization.	2026-02-23 23:57:54 +01:00
