Annual Report Output Metrics Rollup Aggregator Roll up periodic output metrics such as quarterly accessions or reference counts into a count, total, mean, minimum and maximum for annual reporting.
Appraisal Macrovaluation Score Weighted Criteria Calculator Restricted institution-calibrated archival macroappraisal arithmetic, not automatic retention/disposal authority or universal appraisal model. This restricted caller-defined rubric has three independently declared criterion domains: independently assessed societal/function significance, independently assessed evidential value, independently assessed representational/community value. Scores 0–100, nonnegative calibrated weights; known-only normalized mean and unresolved weight retained. No universal validated model, population risk prediction, personal diagnosis or authorization.

Known missing and unknown evidence stay distinct; not approval, compliance, readiness, authenticity or safety certification.
ISO 8601 Date Interval Format Validator Validate a practical ISO 8601 interval subset of the form start/end.
