+# Source summary — EmissionCadenceDeclaration draft
+
+The King's Guard draft proposes a source-authored declaration that makes stream
+silence observable. It distinguishes two forms:
+
+- `expected-rate`: an event-class minimum over a time window;
+- `heartbeat-or-reconciliation`: a positive liveness assertion, a comparison of
+  source and observed counts, or both.
+
+The draft was written against `qonto-assistant` and the Gate House approval
+emission contract. It assigns evaluation to King's Guard and explicitly asks a
+Taxonomy repository to own the schema.
+
+Security-specific content associates event classes with `attributive` or
+`load-bearing` evidence and requires the stronger form for rare, load-bearing
+events. That policy is part of the source context, not the generic core adopted
+by InfoTechCanon.
