-# Purpose: machine-readable current project state. The PRIMARY landed
-# workstream is the Buchholz/Ordinal rank-monotonicity + well-foundedness
-# track (Slice 3+4 Route A arc). The EI-2 termination capture (April
-# 2026) is preserved below as history — it prevents EI-2 from being
-# re-investigated, but it is no longer the whole document identity.
+# Purpose: machine-readable current project state.
+#
+# CURRENCY NOTE (2026-06-21): the ordinal / Buchholz track is RETIRED from
+# echo-types (owner decision D-2026-06-21) — it outgrew the project and is
+# being extracted to its own ordinal-notation repo (physical cut = owner;
+# tracking issue #263; hand-off record
+# docs/echo-types/decisions/ordinal-fidelity-ladder-parked.adoc). The
+# detailed [recent-work] and [current-workstream] blocks below are preserved
+# as accurate HISTORY of the 2026-06-05 → 2026-06-12 arc, NOT live work. The
+# live tracks as of 2026-06-21 are: composition (landed); establishment
+# (Pillars A–D + F closed; Pillar E in-repo complete at the bounded-claim
+# level; order-type fidelity the one OPEN external problem, D-2026-06-14);
+# variance resolved (#243); aggregation generalised (#175). The EI-2
+# termination capture (April 2026) remains preserved below as history.
