+Founder resolved the earlier daily 48h/72h question by introducing one
+coordination frame, initially f=1h. Canonical configuration is
+coordination-engine/config/coordination-frame.json; NetKingdom's compiler
+regenerates the source-derived Qonto fixture alongside source/receiver
+artifacts and records the config digest. The historical Taxonomy draft
+fixture remains a historical worked example. Live admission must supply the
+actual configured frame/interval and preserve per-class scope; the source
+fixture cannot prove that a deployed process emits hourly heartbeats.
