| validation use | Fit, applicability, or transfer question; receiver; decision; claim; qualification window; stop. |
| subject status | Admitted Method, or candidate account plus separately admitted enacted constituent Methods. |
| source situation | Situation-family conditions, actual Work, performers, capability inputs, Systems, Agent-performed Work, direct relations, adaptations, domain results, burdens, and evidence reach. |
| receiving situation | The same positions for actual receiving or held-out Work, including missing facts. |
| discrimination | Condition selected to challenge the claim, why it matters, matched conditions, changed conditions, and unknowns. |
| semantic continuity | Preserved Method semantics, local Work or support changes, and any reusable semantic change returned as a variant question. |
| comparison | Result differences, burdens and deviations needed for interpretation, evidence strength, and unsupported contribution or causal claims. |
| return | Bounded fit, failure, applicability, transfer, or missing-evidence result; direct C.39.RQ, C.32.MWA.PP, B.1.5.CM, or A.3.1.MV return, or a bounded A.3.1.CC observation for a possible A.3.2.DE description, C.37.MP Method representation profile-row, or A.15.8.MS support contradiction; non-transfer and reopen conditions; unaffected results preserved. |
