| CC-CSC-0 (Ordinary entry). | The practitioner names the present use and must-retain distinctions, writes the shorter candidate, compares it with the source, rejects unsupported additions or strengthening, and records loss, non-use, and return before optional identity work. | Makes direct semantic compression the first useful move without admitting a fluent invention. |
| CC-CSC-1 (Exact endpoints when material). | When the candidate must travel independently or exact content identity changes the receiving use, exact X and Y each have recoverable claim content, EntityOfConcern, and effective U.ReferenceScheme. | Blocks a source set, model, graph, evidence set, publication, form, carrier, or readable tile from replacing an episteme. |
| CC-CSC-2 (Exact construction when material). | The same trigger requires exact c : X -> Y with same EntityOfConcern, claim construction, endpoint-scheme relation, preservation, controlled loss, prohibited strengthening, applicability, and return. | Makes a load-bearing coarsening claim testable without making the formal account the ordinary entrance. |
| CC-CSC-3 (Admissible use). | The ordinary candidate names its present use; exact Y has one stated narrower admissible use. | Keeps convenience from becoming broad authority. |
| CC-CSC-4 (Non-admissible use). | The stronger downstream use that needs more than the ordinary candidate, exact Y, or its publication is explicit, together with the limiting loss or missing support. Apply F.19:4 to how that boundary is expressed; retain the actual admissibility condition. | Blocks authority laundering. |
| CC-CSC-5 (Return). | Ordinary return resolves to the directly linked source; an exact account resolves to exact X, an established source relation, a genuine authority source, or the concrete neighboring contribution needed by the stronger claim. | Prevents provenance reset and fictive routing. |
| CC-CSC-6 (Neighbor separation). | Actual Work, additional source epistemes, correspondence, representation, mathematical-lens use under C.29, viewpoint/U.View, grounding, publication occurrence, form, carrier, audience, and bounded use remain separate and use their own definitions, tests, or methods when current. | Prevents a filled coarsening card from becoming an omnibus ontology. |
| CC-CSC-7 (Ordinary economy). | Ordinary cases return the shorter candidate with its directly reachable source after comparison; a separate six-row note is optional. Exact endpoint and construction identity open only when independent transfer or the receiving use makes them material. | Preserves usability without deleting the exact branch. |
