Introduce an explicit provenance + taint + delegation model so untrusted content cannot acquire authority merely by being read. Guarding now enriches every action with required vs delegated authority before PolicyEngine evaluation, with fail-closed pack, APIs, CLI, dashboard, corpus evaluation, and adversarial/property tests. Client trust claims remain untrusted unless verified by the control plane. Co-authored-by: Cursor <cursoragent@cursor.com>
