From c0783340b004800596ee25865f5c2c08459b08e9 Mon Sep 17 00:00:00 2001 From: Joan Date: Mon, 20 Oct 2025 12:22:07 +0200 Subject: [PATCH] Unify all handler signatures and simplify router - Standardize all handlers to signature: (query, user_id, player, data=None) - Replace 125-line if/elif chain with HANDLER_MAP dictionary - Reduce router code by 90 lines (72% reduction) - Add HANDLER_MAP registry for cleaner organization - Enable future auto-discovery and decorator patterns - Maintain full backward compatibility - Document changes in HANDLER_REFACTORING_V2.md Benefits: - O(1) handler lookup vs O(n) if/elif chain - Add new handlers by just updating the map - Consistent signature makes code easier to understand -
