  "tool_version": "1.0.0",
  "mandate_type": "compliance_mandate",
  "purpose": "Book-level Group 2 exposure-limit assessor for banks' cryptoasset exposures (BCBS d545 Prudential treatment of cryptoasset exposures, SCO60.116-119; the corrected successor to the single-position classifier: the 1% figure is a general-expectation threshold, the must-not-exceed limit is 2% of Tier 1). The caller supplies Tier 1 capital in integer minor units and the Group 2 book as per-cryptoasset positions carrying absolute long and short legs already delta-adjusted for derivatives. Legs are aggregated per cryptoasset and each asset is counted at the higher of its absolute long and short totals, never a netted figure; the per-asset figures sum into one aggregate that is assessed against both thresholds by strict cross-multiplied integer comparisons (exposure*100 against tier1*multiplier), so exactly 1% is not crossed and exactly 2% is not breached, and no floating-point rounding can flip a boundary. Below 1%: no finding. Above 1% and at or below 2%: the expectation threshold is crossed - supervisor notification fires and only the excess over 1% of Tier 1 takes the 1250% Group 2b weight, the remainder keeping its own treatment; this band is not a limit breach and the Pillar 3 precheck is unaffected. Above 2%: the limit is breached - the whole aggregate takes the 1250% weight, the precheck fails, and the breach gap and flags fire. The capital input must be a multiple of 100 minor units so 1% and 2% of it and the excess amount are exact integers; zero, negative, fractional or over-cap capital is a typed refusal, never a NaN or Infinity verdict. The caller owns the completeness of the book (every direct holding - cash and derivatives - and indirect holding - funds, ETF/ETN or similar - must be supplied), the delta adjustment of the legs, and the Tier 1 figure; the node classifies no individual asset and applies no infrastructure-risk add-on, which remain the earlier single-position classifier's decisions. National implementation of the standard varies by jurisdiction and no adoption status is asserted.",
