  "notes": "Every Larry turn opens with exactly one De Stijl glyph naming the move (detectVoiceMark's valid contract in lib/hmi/voice-color-mark.cjs). This rule already holds in practice today; declared here (not logged) because no window of evidence has been reviewed by a human yet, even though the same Stop hook and voice-style.jsonl log this phase shipped mechanically evaluates it. min_true_positives is grounded in the same sourced figure as voice-hyphens-only: the 50 to 100 human-reviewed-traces baseline from Vanishing Gradients Ep. 57 (Shreya Shankar), low end adopted as the promotion floor."
