# Plan: Backup Version Reuse (016)

**Branch**: `016-backup-version-reuse`
**Date**: 2026-01-02
**Input**: [spec.md](./spec.md)

## Goal
Reduce unnecessary `PolicyVersion` creation when policies are added to backup sets by reusing an existing suitable latest version where safe.

## Approach
1. Always capture from Intune when a policy is added to a backup set (admin expectation: "backup = current state").
2. Rely on `PolicyCaptureOrchestrator` snapshot-hash reuse to avoid redundant `PolicyVersion` creation when nothing changed.
3. Still respect capture options (assignments / scope tags) via orchestrator backfill behavior.
4. Add tests for both reuse and capture paths.

## Out of scope
- UI toggles/config flags unless required.
- Cross-policy dedup or historical compaction.
