Time limits and cancels

Open orders expire. Makers can cancel their own open order from the ticket and get APU back from escrow. You cannot silently pull inventory after a taker has already opened a deal.

After a reserve, you watch the deal room. If the buyer never funds in 10 minutes, or they Release early, the deal ends and the ask returns to the book. Seller APU stays locked on the ask. That buyer cannot reserve the same order for 30 minutes. Activity lists your orders and deals so you do not cancel the wrong ticket.

If Econext is unreachable, the live book may be empty. That is a connectivity state, not a zero-price market. Retry on the same screen. Do not invent a settled state.
