Variant Matrix Completeness Worksheet

Compare the option space you declare with existing variants and explicit intentional exclusions. Missing combinations are review items and are not automatically catalog errors.

01 · Declare

You define what “complete” means

The worksheet builds a Cartesian product from your option values, then subtracts only the exclusion rules you wrote with reasons. It never infers that an absent combination should exist.

A · Options

Declared option space

Required

Names and values are exact, trimmed, and case-sensitive. ; and = are reserved.

B · Existing

Existing variant rows

Required for comparison

Every valid row must name every declared option. Unknown or incomplete rows stay explicitly unknown.

C · Exclusions

Intentional exclusion rules

Optional, but explicit

A partial rule excludes every matching combination. Overlapping rules are retained, with all reasons shown.

Terminology and problem evidence

Official documentation confirms that product variants are combinations of option values and may be generated or added selectively. The worksheet deliberately does not encode any vendor limit.

These links support terminology and the existence of the operator problem. They do not validate this worksheet against a live store or prove search volume.
