C.22.2:20.1 - Five-Case Worked Slices

These rows are recognition slices, not complete Thin cards. Before using one, complete the exact Thin contract in C.22.2:2.1; add the relation cues shown here only when they change that card’s next use. The compact filled Thin example follows in 20.1a.

CaseProblem-side signalRepaired card useBoundary preserved
AI and human task transfer reworkRepeated rework appears after transfer between human and agent.Stabilize signal, EntityOfConcern, effective ReferenceScheme, ClaimScope, acceptance probe, and safe-call or Work relation before another delegation.The card is not a prompt retry instruction and does not justify another delegation.
Musical mastery tempo driftPractice tempo drifts away from the intended mastery band.State the temporal claim, practice scheme and scope, acceptance probe, and C.27 relation when tempo, rhythm, recovery, or learning rate changes the next use.A trend line is not an intervention model or evidence of mastery.
Customer-service escalation after a policy or interface changeEscalation volume rises after the change.Stabilize affected customer hand-off, acceptance probe, risk boundary, measurement relation, and causal-use relation when that relation is being made.Escalation volume is not an automatic fix request, staffing plan, rollback order, or causal proof.
Literature-synthesis anomaly before method selectionAn anomaly does not fit current category labels.Preserve rival formulation, EntityOfConcern, evidence need, bridge, representation, or mathematical-lens relation when that relation is being made, and next discrimination action.The anomaly is not proof for a new theory or a selected research method.
Selected-set candidate before P2WA retained candidate from a front or pool looks promising.Preserve sourceSetRef, source-set kind, selection or retention criterion, non-scalar next use, and only the currentness or window on which that use relies.Set membership is not selected-solution proof, priority score, or work authorization.
