| Readable assertion vs explicit identity | Engineers need short relation sentences, while some later assertion or description epistemes need one stable occurrence as their EntityOfConcern or designated object and receiving direct relations may need it as a participant. |
| Relation obtaining vs predicate satisfaction | The world-side relation obtains; the actual relation participants, considered under their participant meanings, satisfy the truth-valued condition stated by the semantic predicate. Conflating these substitutes a formal expression for the obtaining relation. |
| Relation kind vs semantic predicate | A relation kind classifies occurrences under an identity rule; a predicate states a satisfaction condition for the jointly considered participants. One is not a synonym for the other. |
| Occurrence vs assertion or representation | An occurrence can exist before anyone asserts, describes, explicitly individuates, names, references, or represents it. |
| Participant identity vs repeated occurrences | In one direct species under U.SystemRoleAssignment, the same complete participant set can recur after a demonstrated predicate-false gap; another direct relation may use a different discriminator only when its own pattern declares one. |
| Construction vs description | A system can create a relation occurrence while performing constitutive work when the direct construction rule says so; that work occurrence may contribute to identity. Producing a row or description episteme is not constitutive by form. |
| Subject-pattern variation vs universal reification | A.6.REL supplies no universal truth-maker, occurrence-identity discriminator, or representation form. Each direct relation pattern supplies its own obtaining and identity settlement; each concrete representation remains under its direct representation pattern and explicit correspondences. |
| Stable reference vs false creation | Identifiers enable later reference, but identifier assignment neither creates the occurrence nor makes the direct relation obtain. |
