Liked Videos as a Key Indication of Signal

This is a position: liked videos are a primary signal source, not a personal archive. The user explicitly treats explicit taste endorsements as higher-signal than implicit ones (watch history, search history, suggested-video clicks).

The framing carries an architectural implication: rich capture per liked video, not voluminous capture. The "what was liked" matters more than the "count of likes."
