Canon 0.4.0: joinable consumer proof and EvidenceBasis

§10.3 now accepts a consumer record that validates against the live
catalog; resource-control's backup restatement is that proof. ITC-GOV
gains EvidenceBasis in tiers (invoiced and measured are peers) and
ITC-CAP requires it on every consumption row (CAP-R10).
