Built by OA agent per VIOLET_SUB_SPEC__L3_EXCHANGE_LEVERAGE.md; reviewed for compliance/flaws. VERIFIED: wraps real prod/bingx/leverage.py (untouched), constants imported from it, NO arbitrary upper caps, exact == bit-identity (1e6 gate 0 mismatches), ROUND_HALF_EVEN explicitly tested (1.5->2 AND 2.5->2), clamping+non-default caps+frozen model. 38 tests pass on independent rerun. REVIEW FIX: to_exchange clamped negative internal_conviction to 0 in the trace field (reused ConvictionLeverage ge=0); changed trace field to plain float (poison guard only) so it records the ACTUAL input faithfully; dropped the clamp + unused import. Relocated 8 off-spec leverage-spike scratch files off repo root -> prod/VIOLET_dev/l3_spike/. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
