How this instrument reaches a result
The category evidence matrix separates buyer and market evidence from company assertion. A confirmed category row requires a buyer problem, budget owner, multiple plausible members, and at least one independent use of the term.

Questions about Category Evidence Builder
What do I leave with?
A versioned category evidence matrix with visible reasoning, evidence status, next action, review date, and structured exports.
Does the result use a benchmark or AI?
No. The result uses the visible deterministic rules for this instrument and only the inputs you provide. It is not compared with other customers.
When does the paid work begin?
After the artifact. Petrichor helps the team challenge evidence, reconcile disagreement, assign ownership, and commit to the organizational decision without making you repeat the free work.
The method is versioned. No cross-customer benchmark is used. Review the full method and change history, the relevant plain-language answer, or the permanent Tool Trust Charter.
