Concurrent readers use positional I/O instead of a shared mutable seek cursor · case 03
Concurrent readers use positional I/O instead of a shared mutable seek cursor.
Case contract
requests are [absolute-offset,count]; return independent ASCII slices for each request. The underlying shared handle cursor is irrelevant.
Why this case matters
Range responses combine representation identity, conditional requests, framing, and partial-object state.
One recorded failure
