Out-of-order downloaded ranges write at their absolute positions · case 04
Out-of-order downloaded ranges write at their absolute positions.
Case contract
ASCII base is a preallocated buffer; offset and part fit within it. Replace that exact span without inserting or appending.
Why this case matters
Range responses combine representation identity, conditional requests, framing, and partial-object state.
