Proposed extension: apply the contributor/reader practice tests to a second scientific claim, rather than only adding later readers of the first package. Passing one package’s delayed unaided explanation and new-error checks would not establish that its lessons fit another argument. Recheck source scope and whether linked lessons teach the new claim’s needed background; record lessons that cannot be reused. Repeat explanation, error-detection and justified-correction checks for each route on the new claim. Count additional authoring, source/link review, learning, revisions and upkeep separately from the first build. Compare with updating a well-organized reusable document collection, not rebuilding from scratch. Savings with maintained understanding and checking remain hypothetical; reuse does not validate the new claim. Basis: 1Cademy’s undated proposal (captured 2026-11-09), not effectiveness evidence.
