Prepare a reversible rollout

The problem

A release is incomplete without a way to recover from a bad deploy.

Practical procedure

Stage files, validate them, atomically move into place and retain an owned rollback marker.

Worked scenario

If a public smoke test fails, move only the newly owned directory to a protected backup path.

Acceptance check

Prove rollback refuses to remove a directory without the expected ownership marker.

Apply the method

Use the related interactive tool to try the concept on an inspectable example. Record the starting assumptions and expected result before changing settings, then compare what the tool actually does. Where the result differs, keep the release marked experimental and document the discrepancy.
