 `f89a3aa` (BH rung 7 — `nextFix` is the LEAST pre-fixed point; reverse-Γ₀
 reduced) and `a096764` (BH rung 8 — Veblen engine monotone in its iterated
 function). This **contradicts** the retirement banner in this file (arc below)

+*Status (reconciled 2026-06-21): the landed artifact is valid and kept —
+no further work on this trajectory.* It compiles `--safe --without-K` with
+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:
+the `OmegaMarkers` ← `Buchholz.Syntax` ← `EchoOrdinal` bridge STAYS; everything
+else under `proofs/agda/Ordinal/` is the consumer-less artifact that MOVES.
+Order-type fidelity to ψ₀(Ω_ω) remains an *open external problem*
+(`D-2026-06-14`) — retirement neither closes nor over-claims it.
