ADR 0053 accepted; adds the scope boundary the umami rework surfaced (credential provisions vs data provisions — analytics' generated siteId return is left to a separate decision) and records the lab proof. Issue 008 marked resolved: the sdk harness and the four adapters are reworked, the symmetric seal removed, and provider-uses-mesh-credential is green.
