Sora Orchestration Architecture — Multi-Device Personal AI Assistant Across 6-Device Fleet

Sora is an architecture (not a product) for a single-operator AI assistant that orchestrates across a 6-device fleet (DESKTOP-SOL01 personal-root, DESKTOP-YESOL company-work-pc, YSH-Server orchestrator, MX Mac Studio team-mac build node, S26 Ultra and Tab S10 Ultra mobile-operator). It enforces blast-radius scoring (tier 0-5), device-tier capability tokens, the Magentic-One dual-ledger pattern (Task Ledger + Progress Ledger), a four-stage hook pipeline (SessionStart / UserPromptSubmit / PreToolUse / PostToolUse), uncertainty-triggered HITL gating, and an Owner Sovereignty Article 0 that distinguishes 'disclose-and-confirm' from 'block.' This note documents the architecture as deployed across personal-root, company-work-pc, server, and mobile tiers with provenance-aware shared brain.
