Maintenance
The repair floor is a sequence, not a mood.
LLM documentation maintenance starts when a change appears small enough to ignore. A parameter is renamed, a model behavior is tuned, an evaluation threshold changes, or a support caveat moves from private chat into public guidance. The floor turns those signals into visible repairs. Each station leaves a record that the next editor can inspect without replaying the whole launch.
