Cocoon Grade Sorting Classifier

Classify observed cocoons by a caller descending shell-percent grade schedule with explicit defect/reject codes; no universal trade grade or health certification.

Description

A grading policy assigns the first qualifying descending shell threshold.

A grading policy assigns the first qualifying descending shell threshold. Defects can override percentage-based grades.

Classify observed cocoons by a caller descending shell-percent grade schedule with explicit defect/reject codes; no universal trade grade or health certification.

When to use Cocoon Grade Sorting Classifier

Use this tool to classify observed cocoons by a caller descending shell-percent grade schedule with explicit defect/reject codes; no universal trade grade or health certification.

Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.

How to use Cocoon Grade Sorting Classifier and understand its results

Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.
Enter shellPercents, defectFlags, descendingMinimumShellPercents, callerGradeCodes, rejectGradeCode using the field table and calculation rules, then run the tool.
Read assignedGradeCodes. 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
shellPercents	Shell percents	list of number	Required
defectFlags	Defect flags	list of number	Required
descendingMinimumShellPercents	Descending minimum shell percents	list of number	Required
callerGradeCodes	Caller grade codes	list of number	Required
rejectGradeCode	Reject grade code	integer	Required

Align shell percents in [0,100] with binary defects, and up to 128 strictly descending thresholds with unique integer codes distinct from reject. Defects and no matching threshold return reject; equality qualifies. Workload is bounded.^[1]

Paired lists must be nonempty and have equal lengths.

grade = first caller code whose minimum shell percent ≤ measured percent

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

Output field	Meaning	Value type
assignedGradeCodes	Assigned grade codes	list of number

Limitations and assumptions

Caller grades are not universal trade grades or health certification.

Numbers and computed results must be finite; overflow 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.

Alternative or Complementary methods

Use Cocoon Price From Shell Percent: Interpolate a supplied auction shell-percent price schedule and quality multiplier without market-price defaults or out-of-range extrapolation. For a complementary task, use Double Cocoon Percent Defect Rate: Audit double-cocoon count share and a caller equal-mass price-discount scenario; count share is not claimed to be measured double-cocoon mass share.
