US06-01 — Configure and Preflight Archive Destinations

Epic: E06

As a user, I want archive destinations identified and validated so an album is never moved to the wrong, unavailable, or undersized storage.

Acceptance criteria

• Archive locations record stable media/volume identity, root, capabilities, and state.
• Preflight validates verified upload, current bytes, destination identity, capacity, writability, boundaries, collisions, locks, backup, and manifest creation.
• Preview shows transfer method, exact scope, reclaimable bytes, and every blocker.
• Confirmation uses a versioned token invalidated by source/destination changes.

Automated tests

• Integration tests cover valid, offline, wrong-volume, low-space, read-only, collision, stale source, lock conflict, and unsafe path cases.

Dependencies

• E05 complete
