The final chemotaxis lesson closes the deterministic gradient-to-motion ledger. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Use the checked net displacement and time
The connected drift ledger has displacement 24 m and total time 24 s.
24m24s
Accept only the connected chemotaxis ledger
The audit accepts because gradient, occupancy, contrast, bias, and drift all cite matching checked sources.
