Picked one by one from a mixed channel. Transcript check: both title readers certain; 4 of 5 sampled certain picks confirmed by transcript, none failed. Channel rule: Include only descriptively titled how-to videos that teach a specific installation or plumbing/tile/electrical technique (e.g., valve installs, drain connections, shower pans, niches, subfloor, blocking); exclude timelapses, makeover/project showcases, course or membership promos, cost videos, and any caps/exclamation clickbait titles.
