What changed
Field record_id was removed from verify_footprint input; consumers still sending it may be rejected or silently ignored. New required field expected_row_sha256 on verify_footprint; requests without it will fail. New required field leaf_index on verify_footprint; requests without it will fail. New required field stamp_day on verify_footprint; requests without it will fail. dataset on verify_footprint narrowed to a closed enum (depin_onchain); previously valid values may now be rejected.
