| trial question | One evidence question whose answer can change a named later decision. | “Try the method” is not yet a bounded question. |
| representative situation | A situation selected because stated characteristics match the named current-use question. | The word does not imply random sampling, population coverage, or transfer. |
| discriminating situation | A situation selected because one changed condition can expose a claimed limit, burden, or failure. | Difference alone is insufficient; state which claim the changed condition can test. |
| WorkPlan | Intended performers, tasks, Methods, situations, observations, and stops. | A plan, script, simulation description, or scheduled demonstration is not performed Work. |
| admitted Work | One dated Work occurrence admitted under A.15.1 from its actual performers, action history, enacted Method, temporal extent, and required containing-System relation. | A report, trace, attendance record, or output can support the claim but does not create the occurrence. |
| candidate-account trial branch | Actual Work is admitted separately while claims in a candidate Method account are compared with observations. | The candidate whole is not said to have been enacted. Only separately admitted constituent Methods may obtain in enactsMethod relations. |
| capability input | A claim about a holder System, Work family or result class, operating envelope, measures, qualification or currentness window, and evidence used for reliance. | Training, availability, assignment, permission, authority, or one success does not substitute for it. |
| trial evidence | Occurrence-level observations, source relations, burdens, adaptations, results, and gaps qualified for named later uses. | It is not itself coherence, fit, transfer, worth, contribution, or causal proof. |
