Subject: [PATCH] fix: Resolve Player.data AttributeError in patch_player
 endpoint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes critical bug where IL moves and team reassignments failed with:
  "type object 'Player' has no attribute 'data'"

Root Cause:
- model_to_dict() with recurse=True attempted to serialize foreign keys
- Peewee internal serialization incorrectly accessed Player.data class attribute

Changes:
- Add backrefs=False to model_to_dict() to prevent circular reference issues
- Add comprehensive exception handling with graceful fallback
- Fallback chain: recursive → non-recursive → basic dict conversion
- Add warning/error logging to track serialization failures

Impact:
- Fixes /ilmove command failures (player team updates)
- Prevents PATCH /api/v3/players/{id} endpoint errors
- Maintains backward compatibility with all response formats

Version: 2.5.1 → 2.5.2
