Read MISTAKES.md before starting any work this session.

MISTAKES.md is a log of patterns that have caused problems in this project before. Every item in it represents something that went wrong and cost time to fix. Treat every entry as a hard rule , not a suggestion.

If MISTAKES.md does not exist yet, create it now using this template:

# MISTAKES.md

*Patterns this AI has gotten wrong in this project. Updated after every incident.*
