05 — Research & Experiments
Validated results and open experiments, clearly separated.
On-device LLM inference
arm64 llama.cpp/GGUF CPU runtime: streaming multi-turn inference, KV-prefix reuse, measured decode throughput and TTFT on Snapdragon 8s Gen 4.
Snapdragon / Hexagon NPU
Qualcomm Hexagon HTP evaluation; first non-CPU backend confirmed with FastRPC/DSP evidence. No acceleration claimed until qualification completes.
Adreno GPU — Vulkan, Turnip, Zink
Mesa Turnip Vulkan and Zink on Adreno 825; Vulkan compute crash at decode root-caused and documented; Zink desktop path measured (glmark2 140).
Consent-gated Android automation
AccessibilityService + Shizuku privileged execution with explicit confirmation, typed operations, and a hash-chained audit trail.
Linux on Android — ARM64 workstation
No-root Debian/Xfce over PRoot with a measured GPU route, plus a phone-first loop where CI builds artifacts and the device validates them.
Native ARM64 tooling from AOSP source
Android SDK build-tools/platform-tools compiled for Linux ARM64/glibc; SHA-256-verified offline artifacts; APK pipeline validated end-to-end on device.
