From 25a0fad3f08be782819a8e0a10b27de81f961fb2 Mon Sep 17 00:00:00 2001 From: immortal71 Date: Tue, 3 Mar 2026 17:20:05 +0545 Subject: [PATCH 1/2] fix: wrap card dealing in Ecto.Multi transaction for atomicity Replaces Repo.insert! loop with Ecto.Multi to ensure all card inserts and the game start update succeed or roll back together. Also adds minimum 3-player validation before starting a game. Addresses ASVS V2.3.3 - database transactions at the business logic level.
