Requires current synapse:event_sources:write authority in the exact environment. Publication pins only a public Ed25519 signing key, event age and capacity bounds, input mode, and the complete run configuration. It neither activates nor starts a run. Activation and retirement require human sessions; enabling also requires an available event admission worker. Preserve exact request and key after an unknown mutation. No automatic retry. Fixed mode refuses event input overrides; event_reference requires an exact current approved JSON content reference, never a raw event body. Replies expose execution_ready; false refuses enabling. Test and Live authority, reset and funding remain separate. Signing private keys must stay with the external source. This metadata API does not expose event admission receipts.
