A.6.REL:6 - Bias-Annotation
This pattern has an individuation bias because it serves receiving uses that need relation identity. The lightweight stop rule prevents that bias from turning every direct relation into an explicit relation-occurrence description episteme.
The admitted system-role-assignment case can over-emphasize participant identities and temporal continuity. Another direct relation may instead use constituting Work or another world-side discriminator, but only when its own accepted pattern states that contribution. The hypothetical installed-part boundary demonstrates why A.6.REL must not invent that rule.
Engineers can easily picture relation instances through data-model examples. When a representation must distinguish an obtaining occurrence, first apply the subject pattern’s obtaining test to the relevant case facts or constituting history, then apply its occurrence-identity rule. A system introduces a database row, graph edge, reifier, or other representation for that declared use only after those steps. Representing an assertion or another claim family does not by itself require an obtaining relation occurrence or explicit individuation.
