 # Resume Branches
 CV control plane that treats your resume like a git tree: preserve one canonical ATS-safe DOCX, branch it into role/company variants, review AI-suggested patches, and publish stable public links without losing structure.

 ## Why Resume Branches exists
 - **Preserve canonical formatting.** We never regenerate the DOCX wholesale; edits are stored as targeted patches on parsed blocks so ATS cues stay intact.
