Local-first AI assistant with multi-model orchestration
Status: Experimental / Proof of Concept
Concept: Manager pattern + Android HID injection
Stack: Android → PC via local/VPN'd Ollama inference
Philosophy: AI sovereignty through local execution (KISS)

Gamified Linux documentation system
Status: Concept stage
Vibe: Cyberpunk-themed sysadmin training adventure
Goal: Transforming dry docs into narrative-driven learning
Because learning should feel like a side quest, not homework.
