A.3.1.WT:0 - Use This When

Use this pattern when a Method or candidate Method account is ready for a trial in actual Work and the next decisions need observations from named situations rather than another plan, demonstration, or document review. Begin with one trial question: what must be learned from actual Work for a later coherence, fit, transfer, or worth decision?

The first useful result is a trial-slice row. It names the subject and its status, the situation-selection reason, the planned task, the Work that actually occurred, actual performers and enacted admitted Methods, relied-on Systems and capabilities, observations, gaps, and the later decision that may use them. A row that returns missing-performed-work is useful when the trial remains only planned.

Here trial is Plain practice wording for intentionally selected Work and observation. It is not a new subtype of U.Work, a Method admission, an evaluation result, or a claim that the situation statistically represents a population.

Do not use this pattern to declare description coherence, situational fit, transfer, practical worth, capability, causal contribution, or general effectiveness. A.3.1.WT makes later judgments possible; A.3.1.CC, A.3.1.FT, and C.11.MV make those judgments under their own questions and evidence.

A.3.1.WT:0.1 - Working Distinctions

Item	Working meaning here	Boundary
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.
