Prepare each acquired content frame into one of two private GPU candidates so the IddCx frame can be released without copying it to IVSHMEM immediately. Wake a high-resolution publisher at the client deadline and send the newest completed candidate. Preserve accumulated damage across superseded candidates, include the scheduling hold in end-to-end timing, and keep transport work on the existing physical copy queue.
