A Delivery carries its Event and Target structs in memory for the delivery engine, so GORM's automatic association save upserted the whole target row -- config included, which holds destination URLs and bearer credentials -- into the per-webhook event database with an empty webhook_id. Event databases are the files most likely to be backed up or handed to someone else, so they shipped the credentials with them. Register a create and update callback on every per-webhook connection that omits associations, rather than fixing the one call site: it covers writes inside a transaction and write paths added later. Sweep any rows already written, before the migration on each open, so it is idempotent and a no-op on a database with no targets table. Encryption of target config at rest in webhooker.db is deliberately not part of this: it is tracked separately.
