A fire-and-forget permission_decision over the observer control channel is lost if the harness socket is down when the decision is published, stranding the card. Close both halves: - Harness (buzz-acp): a retransmitted decision whose nonce was already applied now acks success-shaped (already_decided) via a recently-decided nonce set with a retention window, instead of failing no_active_turn/channel_closed. - Desktop: a retransmit-until-acked orchestrator bounded by the card's expiresAt, with already_decided treated as success (never increments deliveryFailed). Frames without expiresAt fall back to a 300s freshness window from the frame timestamp. Co-authored-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Will Pfleger <pfleger.will@gmail.com>
