+# US06-03 — Preserve Offline Identity and Review Evidence
+
+Epic: [E06](../E06-archive-lifecycle.md)
+
+As a user, I want archived assets searchable and usable for deduplication while their
+media is offline so new copies are not mistaken for unrelated photos.
+
+## Acceptance criteria
+
+- Availability distinguishes active, archived online/offline, and unexpectedly missing.
+- Archived hashes remain in indexes and inventory scans do not prune offline assets.
+- Protected comparison previews and evidence remain available under a durable policy.
+- Exact and fuzzy active matches link to archived canonicals with appropriate review.
+
+## Automated tests
+
+- Integration tests toggle fake mounts, rescan, discover exact/fuzzy copies, review
+  previews, and assert stable state across restart.
+
+## Dependencies
