-# Rational vs irrational lens (mandatory)
-Carry the base prompt's rational-vs-irrational framing through to every
-paragraph of the portfolio read. For each section above, contrast:
-- The RATIONAL read: what the underlying factors (fundamentals,
-  macro/policy regime, valuation, currency dynamics) justify for this
-  exposure;
-- The IRRATIONAL read: what positioning, narrative momentum, sentiment
-  or flows are doing to that same exposure right now.

-the pie's numbers or only the macro backdrop, without placing the
-holding on this rational-vs-irrational axis, is incomplete.
+# DO NOT include in this surface (overrides the base prompt)
+- No "Rational vs irrational" framing, no "Rational:" / "Irrational:"
+  section labels, no parallel contrast lists. The base prompt asks
+  for this framework elsewhere; this surface is plain declarative
+  commentary on the holdings, not a comparative essay.
+- No "System temperature:" closing line. That artefact belongs to the
+  daily strategic log; here the analysis ends with the last paragraph.
+- No "Update mode" headers, no anchor-date callouts, no watch list.
