  No foreign key on events.site_id. The ingest path sustains
  ~10³ rps and the constraint check costs ~5% of the per-request
  budget. Orphan rows are swept by the worker. See D-020.

  The cascade I added is the constraint this repository
  forbids. Reverting turn 7 and 9, and deleting rows in the
  sweep instead.
