+-- Reverses 000004.
+--
+-- Drops exactly what the up migration created and nothing else: no CASCADE on
+-- a schema, no DROP SCHEMA, no DROP DATABASE, and no touch to users beyond
+-- removing the index 000004 added. users_org_email_key predates this migration
+-- and is left alone.
+--
+-- Dropping `sessions` logs everyone out. That is the correct meaning of
+-- rolling back the authentication foundation, and it destroys no application
+-- data: every row in this table is a credential, not a record.
