- Migrate 11 character JSONs from old wardrobe keys to _BODY_GROUP_KEYS format - Add is_favourite/is_nsfw columns to Preset model - Add HTTP response validation and timeouts to ComfyUI client - Add path traversal protection on replace cover route - Deduplicate services/mcp.py (4 functions → 2 generic + 2 wrappers) - Extract apply_library_filters() and clean_html_text() shared helpers - Add named constants for 17 ComfyUI workflow node IDs - Fix bare except clauses in services/llm.py - Fix tags schema in ensure_default_outfit() (list → dict) - Convert f-string logging to lazy % formatting - Add 5-minute polling timeout to frontend waitForJob() - Improve migration error handling (non-duplicate errors log at WARNING) - Update CLAUDE.md to reflect all changes Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
