A sound workflow for an ambiguous name is:
1. Preserve the reading: transcribe what the manuscript actually says before proposing emendation.
2. Separate components: identify given name, father, kunya, and nisbah.
3. Classify the ambiguity: is it script, dots, vowels, word order, or distinct individuals?
4. Test contextual evidence: compare teachers, pupils, generations, locality, and parallel chains.
5. Calibrate the conclusion: mark a reading as probable or unresolved if proof is incomplete.
For example, seeing “Yazīd ibn al-Aswad” does not justify reversing it simply because “al-Aswad ibn Yazīd” is more familiar. First examine the associated biographies and independent chains.
