Picked one by one from a mixed channel. Transcript check: both title readers certain; 5 of 5 sampled certain picks confirmed by transcript, none failed. Channel rule: Include only explicit narrated repair tutorials whose titles describe a specific repair procedure (e.g. 'How To: Replace...', '... Screen Replacement—How To', '... Repair'); exclude teardowns framed as product verdicts, hooks, rundowns, lists, tests and music-only disassemblies.
