    "title": "Neon stopped hiding missing parts behind a generic guardrail.",
    "summary": "The human-review packets now show whether required active lanes stayed measurable in each proof window, so a candidate cannot quietly pass review with a required musical part missing.",
    "whatWentWrong": "The earlier review packet could say required_instruments_preserved, but a reader had to inspect nested JSON to understand whether the required lanes were actually active in every proof window.",
    "whatRiddleCaught": "The new active-lane receipt exposes active_lanes_preserved or missing_required_active_lanes directly in the compact packet.",
    "whyItMatters": "This makes review packets safer without claiming that the mix sounds better.",
    "whatChanged": "LilArcade now adds activeLaneReceipt to compact claim-candidate packets, makes required_instruments_preserved depend on that receipt, and renders an Active Lane Receipts table in Markdown review packets.",
    "whatThisDoesNotProve": "It does not prove subjective mix quality, does not prove the candidate is musically preferred, and does not replace listening review.",
    "technicalReceipt": "activeLaneReceipt.status=active_lanes_preserved with requiredWindowCount=2, windowCount=2, requiredTracks=bass,chord,guitar,rhythmSynth, and missingRequiredActiveCount=0 for bass, guitar, and chord live RiddleNode packets."
