+- Guide: `docs/zeroclaw_orchestration.md`
+- Préflight hardware avant upload:

+# Orchestration ZeroClaw (RTC)
+
+Dernière mise à jour: 2026-02-21.
+
+## Objectif
+
+Rendre les boucles hardware RTC plus robustes:
+
+- préflight USB obligatoire avant upload/flash,
+- session agent ZeroClaw ciblée sur le repo RTC,
+- exécution coordonnée avec `Kill_LIFE` (orchestrateur dual-repo).
+
+## 1) Préflight hardware local
+
+Lancer avant `autoflash.py`, `hw_validation.py` ou tout upload PlatformIO:
+
+```bash
+python3 scripts/zeroclaw_hw_preflight.py --zeroclaw-bin /Users/cils/Documents/Lelectron_rare/Kill_LIFE/zeroclaw/target/release/zeroclaw --require-port
+```
+
+Variantes:
+
+```bash
+python3 scripts/zeroclaw_hw_preflight.py --port /dev/tty.SLAB_USBtoUART
+python3 scripts/zeroclaw_hw_preflight.py --port /dev/tty.usbserial-0001 --port /dev/tty.usbmodem5AB90753301
+```
+
+## 2) Conversation agent ciblée RTC
+
+Depuis `Kill_LIFE`:
+
+```bash
+tools/ai/zeroclaw_dual_chat.sh rtc -m "fais un état hardware et propose 3 actions"
+```
+
+Si credentials manquants, choisir un provider:
+
+- `zeroclaw auth login --provider openai-codex --device-code`
+- ou `export OPENROUTER_API_KEY=... && export ZEROCLAW_PROVIDER=openrouter`
+
+## 3) Boucle recommandée (issue -> PR)
+
+1. Préflight USB (`zeroclaw_hw_preflight.py`).
+2. Prompt court RTC.
+3. Patch minimal RTC.
+4. Tests locaux ciblés.
+5. PR dédiée RTC avec logs/artefacts.
