A.2.6:11.1 - Claim-scope membership boundary

Claim-bearing episteme E_adhesive states that Adhesive X retains at least 85 percent tensile strength on Al6061 for two hours at 120-150 °C under rig edition Calib-v3. It designates exact claim scope G_adhesive.

  • slice_in = {substrate=Al6061, temp=140°C, dwell=90min, rig=Calib-v3}. member(slice_in, G_adhesive) is true.
  • slice_out = {substrate=Al6061, temp=160°C, dwell=90min, rig=Calib-v3}. Membership is false; the attempted use stops.
  • slice_unknown = slice_in, evaluated with an interpretation basis whose required rig-edition resolution is unavailable. Evaluation returns unknown; it neither excludes the slice nor permits the use.

LabEvaluator_A may perform exact membership-evaluation work through the declared USM operation. When a named audit or replay use needs a judgment to persist, a C.2.1 episteme may record it. A table showing the three rows is a C.29 representation.

The same G_adhesive may participate in two independently governed model-applicability relation occurrences and may be referred to by exact applied constraint claims in two A.22 structures. Only a selected obtaining model-applicability occurrence or an exact constraint claim as applied contributes through its corresponding A.22 discriminator; the common scope itself contributes through neither path and neither merges nor identifies the relations or structures. A declared applicability interval in either occurrence description is separate from the actual maximal continuous obtaining extent.
