The paragraph described the old values. It is deleted with them, its generation claim is detached the way a delete detaches it (the day's slot stays spent), and the workout's arrival is raised again so the paragraph is written from the corrected values through the ordinary path, under the same daily cap.
The manual form sends one manual: id per opening and resends it after
an edit. The batch route now treats a MANUAL entry with a manual: id
as an overwrite, the way stats: measurements are: the stored row takes
the new values and the entry reports "updated", or "duplicate" when
nothing changed. Records keyed on the workout are removed under the
personal-records lock and re-derived. Every other id stays
first-write-wins. The status enum gains "updated".
Builds the entry the form sends, posts it through the batch route, reads
it back from the list, re-posts it as a duplicate, and deletes it; a
synced workout is refused.
