Tan grows a reader channel: 閱讀

Verdict: the daily vocab-gated lesson is tan channel 15 (yuedu). It uses the Tsumugu reader contract (PreparedContent, 1 2 3 4 k x, living word-store) and the Qwen/金多恩 audio tan already runs. It is not a Yuedu bot product and not another slice of channel 14.

Channel 14 stays the gym backbone: interest-crossed lore and tsumugu companion readings, ears-only, 97% ± 2, eight encounters. 閱讀 is the desk sitting: 95% known tokens, about ten new types for exposure, weekday-capable, skip legal. Two gates in one library. Stuffing both into 14 would mix length, sitting, and mastery rules.

The Grok Bot cannot run MLX. Fleet already killed audio for bots. Yuedu gold is now a source pin plus an optional path ping. Sources stay at /Users/n1/Research/grok-bot/yuedu-sources.md so the fetch list is not forked.

Whole tan PRD stays unsigned except this slice. No streak: accretion still forbids a daily bar.

Price: a second surface to host (HTML now, iOS reader later) and a Migaku export before the first gated lesson, or the 95% number is the June snapshot pretending.

Flip: if two handmade HTMLs are a worse reader than dropping PreparedContent into tsumugu-core app/, host there. Gate, store, and voice pin do not move.
