House rules — how a channel earns the shelf
- Teaches, shows, or is a labeled primary source — nothing that merely markets.
- No breathless hype — a channel that screams gets the borderline shelf at best.
- Verified feeds only; the registry grows by verification, never by guess.
- Levels L0 CURIOUS → L3 ARCHITECT are the spine; every card carries its rung.
- Course channels shelve by NAMED SERIES (raw recency is wrong there — proven 2026-07-20 when MIT's latest uploads were theater-arts cassettes); creator channels shelve by ranked recency.
Channels verified by hand against live feeds · shelving assisted with AI under the house rules · no embeds, no sponsorships — every link leaves to the source
