From 51153df8dd149c6ab6a579a32354d2284a68fb4a Mon Sep 17 00:00:00 2001 From: Mikkel Georgsen Date: Sun, 1 Mar 2026 04:11:58 +0100 Subject: [PATCH] feat(01-06): implement financial transaction engine - ProcessBuyIn with late registration cutoff and admin override - ProcessRebuy with limit, level/time cutoff, and chip threshold checks - ProcessAddOn with window validation and single-use enforcement - ProcessReEntry requiring busted status with player reactivation - ProcessBountyTransfer with PKO half-split and fixed bounty modes - UndoTransaction reversing all financial effects - IsLateRegistrationOpen checking both level AND time cutoffs - GetSeasonReserves for season withholding tracking - Rake split transactions per category (house, staff, league, season_reserve) - Full audit trail integration for every transaction - WebSocket broadcast for real-time updates - 14 passing tests covering all flows Co-Authored-By: Claude Opus 4.6 --- internal/financial/engine.go | 1238 +++++++++++++++++++++++++++++ internal/financial/engine_test.go | 658 +++++++++++++++ 2 files changed, 1896 insertions(+) create mode 100644 internal/financial/engine_test.go diff --git a/internal/financial/engine.go b/internal/financial/engine.go index 6ced8cb..4eec63d 100644 --- a/internal/financial/engine.go +++ b/internal/financial/engine.go @@ -1 +1,1239 @@ +// Package financial provides the financial engine for the Felt tournament engine. +// It processes buy-ins, rebuys, add-ons, re-entries, bounty transfers, and prize +// payouts.
