A live HLS manifest is a changing view of a moving stream. A saved copy can point to segments that the server later removes from its live window. Keeping the current top-level stream URL is different from keeping a permanent recording. A snapshot of a live manifest does not freeze the underlying media on the server.
Understand the moving window
Live delivery commonly publishes recent media pieces while older ones leave the active window. A player normally refreshes the manifest as playback continues. An old local copy cannot discover new pieces if it no longer follows the live source.
Distinguish a snapshot from an archive
A text file listing media URLs is not a licensed offline download. Whether replay or recording exists depends on the actual service, player and rights. Do not assume that past segment addresses will remain accessible indefinitely.
Use the supported source for recovery
If a saved manifest fails, reopen the current authorized stream through the normal player flow. Avoid repeatedly requesting obsolete pieces or guessing archive paths. Report a fresh playback error with its time if the current source also fails.

An example to work through
A manifest saved at 18:00 may list media pieces no longer retained at 20:00. The text file still exists, but the referenced live window has moved on.
Questions about this topic
Does saving the manifest save the video?
No. It saves references and metadata.
Can a live manifest be a permanent bookmark?
Use the supplied top-level stream URL rather than a temporary manifest snapshot.
