Finding

The shared65 age and two interior ages provide an exact full-rank reconstruction after the six stated relations are retained. The distinction between a rational model and a bounded grid explains their different identification costs.

Reassessment

Audit the full input cost so reverse cap recovery is not counted as a new independent source explanation.
