SYSE.53:5.2 - Two accounts and one definition

A corpus maintainer combines method account A1 and analytical account B1 in one inference. Inspection of their uses, qualified for this constructed example, establishes A1’s applicability to definition editions D1 or D2 and B1’s to D2. The maintained result is a release selection for that use, not a new assertion that all claims in both accounts are mutually true. A1+B1+D2 supplies the required common definition.

Now B2 relies on D3. Keeping two labelled copies of D permits side-by-side study, but does not preserve an inference that silently substitutes one meaning for the other. The maintainer either retains B1, obtains a qualified A2 or correspondence for the revised argument, or reports that the joint use remains unsupported.

A local note on A1 records an observation and remains attributed to its exact base; it changes no requirement. A replacing amendment would change the consuming rule and must be interpreted before the composition is reused. If B’s definition condition is absent, the honest result is an unresolved premise, not the full allowed set {D1,D2,D3}.

Add a third account C1 with allowed definitions {D1,D3}, and let B1’s qualified range for this variation be {D2,D3}. Every pair of A1, B1 and C1 has a witness; their shared triple has none. The maintainer follows the joint condition rather than approving the three pairwise reports. The corpus application in the Engineering Reference (Engineering.Reference:24) continues from such a selection to retained originals, local amendments, complete readers and independent change.

What changes in practice is the question returned after a failed upgrade: the practitioner can name the demand, scope or missing qualification that must change, instead of repeatedly installing combinations and calling the first successful download compatible.
