Cut Grade Point Aggregator

Aggregate caller calibrated cut component assessments while separately retaining mandatory-component vetoes; high weighted score does not override failed local criteria or create a laboratory cut grade.

Description

A weighted score can hide failure of a mandatory component.

A weighted score can hide failure of a mandatory component. Reporting component vetoes separately keeps supplied minimum criteria visible.^[1]

When to use Cut Grade Point Aggregator

Use this tool to aggregate caller calibrated cut component assessments while separately retaining mandatory-component vetoes; high weighted score does not override failed local criteria or create a laboratory cut grade.

Prepare the gemstone measurements, spectra or comparison data and any supplied calibration parameters. Check units, reference conditions and record alignment.

How to use Cut Grade Point Aggregator and understand its results

Prepare the gemstone measurements, spectra or comparison data and any supplied calibration parameters. Check units, reference conditions and record alignment.
Enter callerComponentScores, callerComponentWeights, callerMandatoryComponentMinimums using the field table and calculation rules, then run the tool.
Read weightedCutAssessmentScore, mandatoryComponentShortfallFlags, allCallerMandatoryCriteriaMet. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
callerComponentScores	Caller component scores	list of number	Required
callerComponentWeights	Caller component weights	list of number	Required
callerMandatoryComponentMinimums	Caller mandatory component minimums	list of number	Required

Pair component scores/minimums in [0,1] with positive weights. Return the weighted assessment, binary strict shortfall flags and whether every minimum was met inclusively.

Paired lists must be nonempty and have equal lengths.

weighted score=Σscore × weight/Σweight; shortfall flag=score<component minimum

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
weightedCutAssessmentScore	Weighted cut assessment score	number
mandatoryComponentShortfallFlags	Mandatory component shortfall flags	list of number
allCallerMandatoryCriteriaMet	All caller mandatory criteria met	boolean

Limitations and assumptions

All criteria and scores are supplied. A high aggregate score does not override failures or create a laboratory cut grade.

Numeric inputs and returned numeric values must be finite; an unrepresentable returned value produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.

Alternative or Complementary methods

Use Hearts and Arrows Precision Check: Audit caller aligned eight-arrow angular/radial measurements against declared pattern precision; no automated hearts detection, branded cut certification or correction for lighting/registration. For a complementary task, use Contrast Pattern Grade Estimator: Grade measured spatial RMS luminance contrast under caller independent bands and physical patch areas; differs from temporal scintillation, no laboratory cut grade or perceptual preference is inferred.
