Check examples by hand

Before answering, recompute every given example with your exact formula; if any example differs, your formula is wrong, so rederive it from the stated rules rather than recalling a standard formula.

Designed by OPSIN: it read 24 misses of the unchanged agent on Coding, Haiku 5.5 with thinking off, found 8 of them failed one way (wrong swap formula or fee scaling), and wrote this line aimed at it. Why it fails

Did it fix what it was aimed at? "Check examples by hand" was aimed at wrong swap formula or fee scaling: on the same 96 tasks, 2 such misses with it against 3 without, so it cut the misses it was aimed at. Elsewhere: floored fee before swap 3 against 4; wrong fixed-point scaling in pnl 2 against 3. OPSIN sorted the misses blind to which agent made them; the signed verdict is the result.

Read from 432 paired tasks in 1 notebook, each task against its own notebook’s two controls, with every interval widened for the 11 families read. No notebook preregisters a family: this says where to look, and a notebook says whether it holds. The runs behind it are on each notebook’s page.
