 ### 16.10 Daemon Start Sequence
 
+**IMPORTANT**: supervisord has NO systemd unit — it is NOT auto-started on reboot.
+After any reboot or OOM kill, supervisord must be started manually (step 2 below).
+
+```bash
+# 1. Verify Hazelcast/Prefect are running (systemd-managed, survive reboots)
+systemctl status dolphin-prefect-worker
+
+# 2. Start supervisord (MUST export DOLPHIN_LOG_ROOT — used by logfile= directives)
+mkdir -p /tmp/dolphin_logs/supervisor /tmp/dolphin_logs/trader
+DOLPHIN_LOG_ROOT=/tmp/dolphin_logs supervisord \
+    -c /mnt/dolphinng5_predict/prod/supervisor/dolphin-supervisord.conf
+# dolphin_data group (OBF, ACB, MHS, exf, maras, esof) starts automatically
+
+# 3. Verify data pipeline is up
+supervisorctl -c /mnt/dolphinng5_predict/prod/supervisor/dolphin-supervisord.conf status
+
+# 4. Start BLUE (manual — autostart=false; only start after verifying BingX position state)
+supervisorctl -c /mnt/dolphinng5_predict/prod/supervisor/dolphin-supervisord.conf \
+    start dolphin:nautilus_trader
+
+# 5. Prefect deployments run on schedule (daily):
+#    paper_trade_flow.py   ← 00:05 UTC
+#    nautilus_prefect_flow ← 00:10 UTC
 ```
-1. docker-compose up -d          ← Hazelcast 5701, ManCenter 8080, Prefect 4200
-2. supervisord (auto)            ← starts dolphin_data group automatically on boot
-   └── exf_fetcher, acb_processor, obf_universe, meta_health start in parallel
 
-3. (Manual when needed):
-   supervisorctl start dolphin:nautilus_trader   ← HZ entry listener
-   supervisorctl start dolphin:scan_bridge       ← when DolphinNG6 active
+### 16.12 CRITICAL — supervisord.conf Safety Rules
 
-4. Prefect deployments (daily, scheduled):
-   paper_trade_flow.py           ← 00:05 UTC
-   nautilus_prefect_flow.py      ← 00:10 UTC
-   mc_forewarner_flow.py         ← daily
+**RULE 1 — Never use /tmp paths for trader binaries.**
+`/tmp` is writable but survives reboots on this host (not a tmpfs). However, directories
+created by agents (e.g. `/tmp/blue_runtime_mirror/`) may be manually cleaned or never
+recreated after an OOM kill, leaving supervisord unable to start the process.
+**Canonical paths for all trader programs MUST reference `/mnt/dolphinng5_predict/`.**
+
+**RULE 2 — nautilus_trader correct config (BLUE live mainnet):**
+```ini
+command=/home/dolphin/siloqy_env/bin/python3 /mnt/dolphinng5_predict/prod/nautilus_event_trader.py
+directory=/mnt/dolphinng5_predict/prod
+environment=PYTHONPATH="/mnt/dolphinng5_predict:/mnt/dolphinng5_predict/nautilus_dolphin:/mnt/dolphinng5_predict/prod",DOLPHIN_LOCAL_RUNTIME_ROOT="/mnt/dolphinng5_predict",...
+```
+
+**RULE 3 — OBF starvation → BLUE freeze.**
+If `obf_universe` dies and is not restarted, BLUE logs
+`"OBF step_live: no snapshots for N consecutive bars — OBF gate degraded to random"`.
+After ~60 bars (~10 min) without OBF the survival stack degrades to TURTLE/HIBERNATE,
+blocking new ENTERs. The existing open position stays open in RETRACT. Fix: restart
+supervisord (which brings OBF up), then restart `dolphin:nautilus_trader`.
+
+**RULE 4 — Before restarting BLUE after a gap, check for open positions.**
+If BLUE was in RETRACT when it died, there MAY be an open position on live BingX mainnet.
+Check `/tmp/dolphin_capital_checkpoint.json` (last capital) and `/tmp/nautilus_trader.log`
+(last V7 decision) for context, but verify directly on BingX before restarting.

+### 16.13 OOM Recovery Runbook (post-reboot)
+
+```bash
+# Confirm nothing is running
+supervisorctl -c /mnt/dolphinng5_predict/prod/supervisor/dolphin-supervisord.conf status 2>&1 || echo "supervisord down — need to start"
+
+# Check BLUE's last known state
+tail -5 /tmp/nautilus_trader.log
+cat /tmp/dolphin_capital_checkpoint.json
+
+# Restart supervisord (data pipeline only — do NOT auto-start BLUE)
+mkdir -p /tmp/dolphin_logs/supervisor /tmp/dolphin_logs/trader
+DOLPHIN_LOG_ROOT=/tmp/dolphin_logs supervisord \
+    -c /mnt/dolphinng5_predict/prod/supervisor/dolphin-supervisord.conf
+
+# Give services 15s to reach RUNNING state
+sleep 15
+supervisorctl -c /mnt/dolphinng5_predict/prod/supervisor/dolphin-supervisord.conf status
+
+# Verify OBF is connected (look for "subscribed" in first 30 lines of log)
+head -30 /tmp/dolphin_logs/supervisor/obf_universe-error.log
+
+# Only then, start BLUE after manually confirming BingX position state
+supervisorctl -c /mnt/dolphinng5_predict/prod/supervisor/dolphin-supervisord.conf \
