+*Status (reconciled 2026-06-21): the landed artifact is valid and kept —

+zero postulates and stays in the green closure; the climb is *not continued*
+and *no new ordinal rung is to be opened here*. The disposition is extraction
+to its own ordinal-notation repository. Echo Core never depended on this track:
