Compile a liquid-handling plan (Flex robot, pipettes, deck labware, liquids, transfer/distribute/serial-dilute/mix/delay steps) into a self-contained Python protocol, run a static volume tracker and a real opentrons simulation, and return a pass/fail report with platemap, reagent-usage, and simulation-log artifacts. This proves the protocol runs, never that the experiment is scientifically valid.
