WAV/AIFF streams and audio handoff buffers

Stopped file ownership after paired clocked device retirement

The device open_reclaimable_clocked_duplex route can reclaim a W215 buffered file/capture processor only after all four native callback guards have retired and the control worker owns their shared cell exclusively. A paused stream or pending retirement does not expose a file consumer. The stopped result can be consumed into the original processor and both matching raw capture endpoints; consuming the buffered wrapper then returns its original file/DSP owners after once-only deactivation. Control may perform the existing stopped worker indexed seek and explicitly prepare/open a fresh clocked pair. Failed seeks retain queue/cursor/ generation as specified by the file worker; success adopts its exact suffix.

Converted/prefetched capture histories are disposed on control, with no rollback, file state restoration or physical clock alignment inferred. The explicit recovery coordinator waits old callback proof before invoking the caller's restoration policy. No native live seek mailbox, automatic file-state migration or new device validation claim follows. See audio devices and decision 0231.
