C.22:1.2 - ProblemCard relation

ProblemCard is the C.22.2 C.2.1 episteme used to stabilize one problem-side representation before downstream Principles-to-Work.

A ProblemCard can prepare TaskKind, scope, and characteristic bindings for a candidate TaskSignature. Assignment obtains only when one signature is adequate for the named receiving use. If several signatures remain plausible, keep them as candidates under the selection or problem-framing pattern rather than asserting one assignment occurrence.

TaskSignatureAssignmentRelation moves no card claim into the TaskSignature. The signature keeps only its A.6.0 declaration content; the card remains the reviewable problem-side episteme that explains why this problem can proceed to characterization, comparison, search, refresh, retirement, or another subject pattern.

The corresponding claims remain with their named subject patterns.
