Row type	Option	Fit	Mandatory check	Tradeoff	Evidence revision	Commercial scope	Decision and reason
Technical route comparison	Supported drive combination	A motor, feedback and controller relationship must be preserved.	Firmware, mode, parameters and permitted restoration.	An electrical connector match is only one condition.	Original evidence pending	To define	To review
Technical route comparison	Reducer condition comparison	Speed, loading or reversing behaviour drives the decision.	Ratio, definitions, mounting and allowed load conditions.	One low lost-motion value is not whole-system accuracy.	Original evidence pending	To define	To review
Technical route comparison	Object-centred tooling choice	The task depends on contact, retention and release.	Object, utilities, attached load and failure behaviour.	Tool acknowledgement is not a conforming handled object.	Original evidence pending	To define	To review
Technical route comparison	Harness and routing replacement	The complete moving electrical connection must be preserved.	Pin map, reference, shielding and intended travel.	Static continuity does not establish motion behaviour.	Original evidence pending	To define	To review
