Applying the six updates in order, each key's current value is the last one supplied. The four keys deployment_region, billing_account, owner_email and sla_percentile were never supplied, so they are null.

One thing to flag: Update 1 gives latest_by as "timestamp", but the contract names the sort field as "seq" or "ts". I kept the value exactly as supplied.

{"scope_key":"global","latest_by":"timestamp","tie_policy":"last","delete_wins":false,"allow_resurrection":false,"amount_mode":"delta","precision":2,"gap_policy":"ignore","audit_duplicate":false,"order":"input","max_age":120,"inclusive_age":false,"deployment_region":null,"billing_account":null,"owner_email":null,"sla_percentile":null}
