Server instructions

FillStub: the caller's own options trading journal, rebuilt from their broker exports. Every contract's real lifecycle (rolls chained, assignments turned into share lots, index options settled in cash), the Section 1256 versus Form 8949 split, and per-strategy statistics where every estimate carries a day-clustered 95% interval. Read the intervals: a win rate of 0.8 over ten sessions has an interval from 0.5 to 1.0 and means very little. The tax tools produce a worksheet, not a filing, and they say what they cannot compute rather than leaving it out.
