Viktor is setting up an Android app development pipeline (tripit is the first app) and wants agents to natively test changes on Android before shipping. This adds the testing environment: an API-36 Google emulator under KVM as a privileged pod (namespace joins the Kyverno exclude list), SDK/system-image/AVD on a proxmox-lvm PVC, adb on the shared MetalLB IP 10.0.20.200:5555 (LAN only), noVNC screen view at android-emulator.viktorbarzin.lan. Image is built manually from the stack's docker/ dir (rare rebuilds; off-infra-CI rule targets repeated builds). First infra ADR records the trade-offs (devvm/VM/redroid/budtmo rejected).
