+## Phase 1.6 — Live device path verified (2026-10-03)
+- Push infra fixed: `b00312c` + `e91d185` pushed to origin/main (Cloudflare issue cleared).
+- `uvicorn app.main:app` now loads config.yaml (module-level `app`); bind `0.0.0.0:8766`.
+- Live handshake VERIFIED via `wss://zhi.moreminimore.com/ws/xiaozhi`: hello→hello OK, device `xiaozhi-main` auth accepted.
+- Root cause of earlier auth rejections: stale server process (pre-config-fix code) holding port 8766.
+- Device token documented above; ESP32 device (muma) flashed to xiaozhi v2.5.0 factory bin via esptool (COM3, backup kept).
+- Next: point device OTA at `wss://zhi.moreminimore.com/ws/xiaozhi`, verify real firmware handshake (CON-004).
