From b04219d2085c67d0493c420dfe1765a06cdffcda Mon Sep 17 00:00:00 2001 From: Cal Corum Date: Wed, 18 Mar 2026 15:54:37 -0500 Subject: [PATCH] feat: WP-13 post-game callback hook for season stats and evolution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit After complete_game() saves the game result and posts rewards, fire two non-blocking API calls in order: 1. POST season-stats/update-game/{game_id} 2. POST evolution/evaluate-game/{game_id} Any failure in the evolution block is caught and logged as a warning — the game is already persisted so evolution will self-heal on the next evaluate pass. A notify_tier_completion stub is added as a WP-14 target.
