B.4:10.1 - SoTA-Echoing

The phase rhythm has historical lineage in iterative cycles such as Plan-Do-Check-Act and Observe-Orient-Decide-Act. B.4 adapts that lineage rather than treating those labels as an ontology: it distinguishes design-time accounts from run-time use, applies a kind-specific identity rule, identifies actual Systems and dated Work, admits internal acting-side splits, and keeps evidence, deployment, publication, acceptance, and renewed use separate.

The result is a practical review language for repeated adaptation. It avoids both agentless “self-evolution” stories and the opposite mistake of requiring every acting System to be external. Canonical means the four questions recur; it does not mean every subject or project follows one identical history.
