Get what changed in one or more activity items
Admin only. Report what changed between two Keryx clocks — for spreadsheets, the per-cell before/after values; for documents, the inserted and deleted text; for presentations, the affected slides. Take the clocks from the activity endpoint. Computed by the same differ the in-app Activity pane renders, so the payload matches what a user sees. Always inspect delta.coverage: caps and non-decodable bulk regions are reported there rather than silently omitted.
