On 2026-09-30 PWCM's stop was moved, and Alpaca's replace returns a NEW order id.
The trader kept the dead id, so reconcile treated the stop as gone and tried to
arm another one (refused with 403, shares held) about 20 times in 80 s, and the
trail exit could not sell because it cancelled the stale id.
- Adopt the id returned by replace. Reconcile follows replaced_by, and before
arming it adopts any working sell stop already at the broker.
- Exits cancel every open order on the symbol before close_position.
- If the price is already through the stop, close instead of arming a stop the
broker would reject.
- tests/unit/test_judge_live_exits.py covers these cases and the 2026-09-29 ones.
