    "Depth can change before any execution. The estimate excludes queue priority, latency, replenishment, market impact, rebates and order routing. Captured minimum size and tick size are informational; this is not order eligibility validation. Unfilled shares have no inferred price.",

    "At most 2000 levels per side and 8 decimal places per price/size are accepted. Gross notional is exact to 16 decimal places; VWAP is rounded half-up to 12. This request does not add a market to collection or write account data.",

    "Estimated taker-buy fees sum shares \u00d7 rate \u00d7 (price \u00d7 (1 \u2212 price))^exponent for each consumed price level. HowSure rounds each level half-up to 5 decimals before summing. The venue documents 5-decimal fees but not its tie rule; actual fills and rounding may differ.",
    "The model receives the covered shares and adds fees in collateral; it excludes builder surcharges, rebates, funding, withdrawal, conversion and other intermediary charges. A modeled zero requires verified parameters and depth; unknown fees are never zero.",
    "Book and fee parameters are separate bounded reads, not an atomic quote. Parameters and identity expire after two minutes; stale, unsupported, empty and sell estimates cannot produce a purchase total. Partial depth has no total for the requested remainder."
