C.2.1:5 - Semantic triangle as a didactic projection (informative)
The Symbol-Concept-Object triangle is a teaching projection, not the episteme ontology.
| Triangle corner | C.2.1 projection | What the projection suppresses |
|---|---|---|
| Symbol | selected representation elements and any publication carrier | representation scheme, admitted operations, publication occurrence, and correspondence to the episteme |
| Concept | U.ClaimGraph interpreted under an effective U.ReferenceScheme | claim scope, justification, viewpoint, and edition relations |
| Object | exact EntityOfConcern and any current EpistemeEmpiricalGroundingRelation | the difference between what claims concern and the holon through which they are empirically inspectable |
A triangle diagram may be used to introduce expression, meaning, and subject if its caption says that it compresses the C.2.1 episteme ontic. Its corners and arrows are representation elements. They supply no SlotKinds, direct relation occurrences, or identity rules.
This limitation matters in practice. A proof-assistant term, wiring diagram, clinical chart, learned embedding, or verbal explanation can all occupy the Symbol corner while supporting different operations and different losses. Those questions belong to the representation-scheme and transition patterns; one geometric picture does not answer them.
