Ring Composition Circular Return Checker

Audit independently annotated nested ring-composition motif pairs, leaving odd center unpaired; no semantic similarity or author-intent determination.

Description

Ring composition compares motifs at corresponding outer positions in a text's structure.

Ring composition compares motifs at corresponding outer positions in a text's structure.^[1]

Equality of caller annotations is evidence about that pattern, not automatic literary interpretation. Use Ring Composition Circular Return Checker to evaluate the supplied inputs under the model explained below.

When to use Ring Composition Circular Return Checker

Use Ring Composition Circular Return Checker to evaluate the supplied inputs under the model explained below. Choose the applicable era, source or grammatical convention and independently establish the annotations or numerical assumptions.

How to use Ring Composition Circular Return Checker and understand its results

Choose the applicable era, source or grammatical convention and independently establish the annotations or numerical assumptions.
Enter Independently annotated section motif ids using the field table and validation rules below, then run the tool.
Read Matched Outer Pair Indices, Unmatched Outer Pair Indices in the Result object; interpret the units, signs, ordering and unknown-value placeholders described below.
Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.

Input field	Meaning	Value type	Requirement
independentlyAnnotatedSectionMotifIds	Independently annotated section motif ids	array of string	Required; constraints below

Enter at least two nonblank independently annotated section-motif IDs. Compare pairs [i,n−1−i] for i from zero through floor(n/2)−1, partitioning them into exact matches and mismatches. ID repetition is allowed and an odd central section is omitted. Pair indices are zero based; no text parsing, motif discovery or compositional-intent verdict is produced.

outerPairs=[i,n−1−i]; matched iff motif[i]==motif[n−1−i]

Use the field order, units and branch conditions described above.

Output field	Meaning	Value type
result	Object containing the named result fields below.	object
result.matchedOuterPairIndices	Matched Outer Pair Indices	array of arrays
result.unmatchedOuterPairIndices	Unmatched Outer Pair Indices	array

Limitations and assumptions

Equality of caller annotations is evidence about that pattern, not automatic literary interpretation. Apply the exact scope and assumptions explained above.

All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
