Each multipart range begins with its own absolute seek · case 02
Each multipart range begins with its own absolute seek.
Case contract
Return ordered abstract I/O operations: seek target if cursor differs, then read length even for zero length; equal cursor avoids redundant seek.
Why this case matters
Range responses combine representation identity, conditional requests, framing, and partial-object state.
One recorded failure
