Detailed Description

Report-only O(1) trade fold (DESIGN 3.3:515-533,547-553).

One accumulator per existing TradeFilter ALL/LONG/SHORT. Initialization and filtering match compute_trade_stats; fold is exactly its loop body, finish exactly its tail. Sums are plain left folds from 0.0 in row order, with the existing NaN, positive-loss and even-trade conventions; no sort, compensation or reuse of the engine's differently seeded running counters.

Fold sealed rows first, then finish a COPY with the unsealed tail and the final, re-marked range-end rows (3.3:547-551). Copies preserve the prefix; finish() never consumes or mutates it, so repeated report reads agree. The implementations replace the old loop only in L7a; none are supplied here. Report state is added to the broker hash waiver list by that lane, not silently treated as new decision state (3.3:552-553).
