monitoring: use inference fix branch by default; harden GUI chain ANR wait

Default BUILD branch fix-bank-withdraw-auto-exchange; dismiss System UI
ANR before confirm taps so low-RAM emulators fail less uselessly.

 - **I-and-gui-004** — emulator RAM cost (this host ~3.7 GiB)  
 - **I-and-gui-007** — for reliable withdraw GUI, build/install app from **fix/bank-withdraw-auto-exchange** or **fix/withdraw-spinner-fallback**, not plain master alone  
 
-Recommended demo stack:
+### Ground rule (ops)
+
+1. **Bring it to run** first (scripts + live stack).  
+2. **App code changes only if needed**, and **minimal**.  
+3. Prefer **existing** `dev/hernani-inference/*` branches over new ones; extend them rather than forking random trees.

+`run-android-build-and-smoke.sh` defaults `BRANCH=dev/hernani-inference/fix-bank-withdraw-auto-exchange`
+so source smokes pick up the GOA exchange auto-add fix without manual checkout.
+
+### Runtime note (clementine)
+
+On ~3.7 GiB hosts the emulator often shows **System UI isn’t responding** before Confirm is tappable. Chain script now prioritizes **Wait** over hunting Confirm. For a green end-to-end GUI path use a physical device or more RAM — the **mint + deep-link + fix-branch APK** path is otherwise ready.
