How copying behaves
The connection drops while an order is being sent
Replica never re-sends it blindly; that follower waits for the broker.
- Replica does not send the order again. The follower is marked as unknown on disk, so even a restart cannot re-send it.
- It waits for the broker’s own answer. The other followers keep copying.
- The follower resumes by itself once the broker shows it flat with no working orders. Nothing is sent just to “fix” it.
An entry that reaches Replica more than 15 seconds late is not chased at a moved price. Exits are always copied.
