+# US04-01 — Build and Export Rename Plans
+
+Epic: [E04](../E04-guarded-renaming.md)
+
+As a user, I want a complete validated rename plan before mutation so I can understand
+every source, destination, collision, and blocker.
+
+## Acceptance criteria
+
+- Approved album proposals produce itemized plans with asset IDs, source/destination,
+  expected hashes, versions, and required operations.
+- Validation detects missing/changed sources, duplicate targets, case-only and Unicode
+  collisions, root escapes, symlinks, and cross-filesystem behavior.
+- A portable JSON export contains no credentials and has a schema version/checksum.
+
+## Automated tests
+
+- Property tests validate collision-free plans and asset-set preservation.
+- API/golden tests cover valid, invalid, stale, case-only, Unicode, and exported plans.
+
+## Dependencies
