-opp-dm.py: Operator Direct Messages
+opp-dm.py: Operator Direct Messages (fixed)
 
-For operator-to-operator communication (646, operator-main).
+Works from container OR from bl directly.
-Operators have SSH access and infrastructure tools.
+Detects environment and acts accordingly.
-This is bidirectional and reliable.
+Verifies writes.
 
-Distinct from dev-dm.py (for task agents: muse, pip).
+For operator-to-operator: 646, operator-main.
-
-Usage:
-  opp-dm.py send --to 646 "message"        # operator-main -> 646
-  opp-dm.py send --to operator-main "msg"  # 646 -> operator-main (via SSH)
-  opp-dm.py read [--from 646]              # Read operator messages
