Why AI Confidently Makes Things Up: From Root Causes to Practical Engineering Strategies

LLM hallucination is not an occasional bug -- it's a systemic risk baked into the architecture. A breakdown of root causes, engineering countermeasures, and why AOSP development workflows are a natural safety net for AI agents.
LoRA Space Navigation: Three Ways to Specialize LLMs Without Fine-Tuning

LoRA parameter space can be programmatically navigated -- no gradient descent needed. A survey of 15+ papers across three research schools (generators, routers, mergers) and what they mean for agent systems.
From Binary Releases to Behavior Releases: The New Problem with Android On-Device AI

When Android apps become agent-callable tools and on-device models become part of runtime behavior, the release artifact is no longer just a binary that passed tests.
Why ALSA Loopback Can't Capture Audio on Amlogic S905X4

ALSA loopback on S905X4 captures silence because the Amlogic Audio HAL intercepts PCM before it reaches the hardware pins, routing it through Dolby MS12 via an internal SPDIF path invisible to ALSA.
SELinux Multi-SoC Policy Architecture: From Pitfalls to Design Contracts

When an Android platform supports multiple chipsets, the layered design of SELinux policy determines the ceiling of maintenance cost. This post walks through the three-layer protection model, common directory layout traps, and how to govern cross-SoC sepolicy with contracts instead of folders.
