# Data Safety & File Operations

## Core Principles
- **Never delete without approval** - Always ask before removing content
- **Preserve everything when merging** - Only remove verified exact duplicates
- **Verify before moving** - Check destination exists, update all `[[wikilinks]]` after
- **Read before writing** - Use Read tool before editing any file

## File Operations
- Use `mv` not `cp` (avoid duplicates)
- Never move numbered folders (00-06) from vault root
- Get approval for bulk operations affecting 5+ files

When proposing bulk operations:
- Explain what's changing and why
- List files affected
- Provide rollback approach
