Use the shared nonblocking, no-follow regular-file opener at the source-read boundary and report a nonregular replacement as changed. Keep descriptor identity and extent checks. The compiled subprocess regression timed out on the baseline and completes without a FIFO writer after this change. Reference reader failure, capacity, cancellation, and import checks pass.
