1. Specify the claim: Which narrator is allegedly alone from which teacher, and regarding what wording or meaning?
2. Write the full initial chain: identify each link and the Companion.
3. Compare the texts: determine whether agreement is verbal, near-verbal, or only semantic.
4. Trace further chains: seek another pupil of the same teacher, higher points of convergence, and other Companion routes.
5. Classify the finding: state whether it is complete, partial, verbal shahid, or semantic shahid.
6. Assess strength: analyze continuity, precision, independence, and contradictions before deciding how much corroboration is achieved.
A technical label should follow the evidence, not be guessed as soon as similar wording is spotted.
