Is the market in profit or at a loss? It depends on which cost basis you ask. Puts the three BTC cost-basis measures side by side — Realized Price (unweighted), True Market Mean (cointime-weighted) and Vaulted Price (dormant holdings only) — with spot measured against each, and flags the case that matters: `sign_conflict` is true when spot sits BETWEEN them, i.e. one measure says profit and another says loss at the same moment. That state is invisible to anyone who queries realized price alone. Also returns the active/vaulted supply split. ⚠️ Supply figures are cointime-weighted, NOT coin balances: active + vaulted legitimately exceeds circulating supply, so total_counted is not a supply number (the payload states this). All values come from one snapshot; source Cointime Economics (ARK×Glassnode) via BRK. Descriptive — no statement about future price direction.
