• Operate the rclone-based migration runtime with secure credential handling (Kerberos keytab, STS role assumption) and KMS-encrypted destinations.

• Build post-migration reconciliation checks: object count/size, checksums, drift detection, version completeness, and configuration parity.

• Track and enforce the point-of-no-return cutover, including owner acknowledgment and sealing of the source.

• Implement governance for bandwidth, queues, prioritisation, and throttling across concurrent migrations, with DynamoDB-backed state tracking.
