  "description": "Mark a position to a given price for equity snapshots. Call when portfolio marks without a live exchange feed in the tool itself. Returns position value at mark as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.",
