-### Technical Insights -- **Security-first development**: Agent validation caught 3 HIGH severity issues before production -- **Input validation is critical**: ZDOTDIR extraction needed sanitization to prevent injection -- **TOCTOU vulnerabilities**: Race conditions exist even in simple bash scripts -- **Empty state validation**: Must validate backup contents, not just existence -- **Format validation**: Backup directory names must match expected pattern -
