- An ad-hoc request made while its target's run is under way is the run after it: the scheduler dropped a second fire of a running id, so a second Takeout file was never imported and its key stayed queued until a restart. - Un-marking or resetting a video is remembered (video_unmarks): an import of an older YouTube view no longer marks it watched again; un-marks take the user's Takeout lock. - One user's failure in the Shorts job's Takeout pass is theirs: the job keeps its own result, the others are settled, and a failed lookup spends none of the daily share. - The upload reads the user's id before giving the read connection back. - A watched row waits on a discovery video (search or explore) until the catalog keeps it, so a mark never pins it against the cleanup jobs. - The history is decoded a window at a time, a Watch later file over 2 MiB is refused unread, and two uploads at once across all users (takeout_server_busy). - A Watch later list goes in as one presence read and one insert.

Un-marking or resetting a video leaves no `video_states` row, so this is what tells an import of the

user's YouTube history a video they un-marked here from one never touched.
