A.1.CSD:11 - Rationale
A.1.SCR answers whether one proposed entity is a System. A.1.CSD begins after a focus is current and asks which other Systems may undergo relevant changes. Merging the two would burden every systemhood check with an open-ended consequence search and would confuse candidate generation with recognition.
A.1.STM locates one unsupported answer across a long dependency; C.28 qualifies one causal-use claim; C.11.CRC constructs a finite comparison. None generates the bounded bearer/path/change account at comparable effort. A.1.CSD therefore stays a thin sibling in the A.1 family and returns each stronger claim to its direct owner.
The result remains an ordinary C.2.1 episteme because the recurring need is a reusable set of qualified claims, not a new world-side kind or relation. One focus fixes the account’s EntityOfConcern within its C.2.1 identity triple; claims about several bearers give it content.
