# Project Rules

## File Editing Safety

- When editing files in this repo that may contain Chinese text, treat encoding preservation as mandatory.
- Never use PowerShell write commands such as `Set-Content` or `Out-File` for file edits unless UTF-8 encoding is explicitly controlled and verified.
- Prefer `apply_patch` for manual edits.
- If a script-based or shell-based edit is unavoidable, use tooling that reads and writes explicit UTF-8 and inspect the diff immediately after the edit.
- After editing `.vue`, `.js`, `.ts`, `.json`, `.md`, or other text files that may contain Chinese, check for mojibake, garbled Chinese, or illegal characters before considering the edit complete.
