"""
Tests for the WP-13 post-game callback integration hook.

These tests verify that after a game is saved to the API, two additional
POST requests are fired in the correct order:
  1. POST season-stats/update-game/{game_id}   — update player_season_stats
  2. POST refractor/evaluate-game/{game_id}    — evaluate refractor milestones

Key design constraints being tested:
  - Season stats MUST be updated before refractor is evaluated (ordering).
  - Failure of either refractor call must NOT propagate — the game result has
    already been committed; refractor will self-heal on the next evaluate pass.
  - Tier-up dicts returned by the refractor endpoint are passed to
    notify_tier_completion so WP-14 can present them to the player.
