+# US06-02 — Transfer, Verify, and Remove Active Sources
+
+Epic: [E06](../E06-archive-lifecycle.md)
+
+As a user, I want source files removed only after durable archive verification so
+reclaiming space cannot cause data loss.
+
+## Acceptance criteria
+
+- A journal records planned, transferring, verified, removing, and terminal item state.
+- Cross-filesystem flow copies to a temporary destination, closes, hashes, atomically
+  publishes, records manifest, then removes the matching source.
+- Same-filesystem optimization is used only when proven safe and still verified.
+- Unexpected source/destination changes stop the item without overwrite or deletion.
+
+## Automated tests
+
+- Filesystem/process tests interrupt every transition before and after source removal.
+- Tests assert manifest/hash correctness, idempotent recovery, and zero verified loss.
+
+## Dependencies
+
+- US06-01, US02-03
