+#+TITLE: PROJECT: Personal Server Appliance (Universal Literate Note)
+#+ID: project-personal-server-appliance
+#+STARTUP: content
+#+FILETAGS: :hardware:server:sovereignty:modular:psf:
+
+* Overview
+The **Personal Server Appliance** project aims to design and develop a modular, high-integrity computing environment. It features swappable modules for compute, storage, networking, and signal processing, packaged in a sleek 10-inch or standard 19-inch form factor that resembles high-end audio equipment.
+
+* Phase A: Demand (PRD)
+:PROPERTIES:
+:STATUS: FROZEN
+:END:
+
+** 1. Purpose
+Define the requirements for a modular, user-serviceable, and aesthetically pleasing personal server.
+
+** 2. User Needs
+- **Modularity:** Unified backplane for swappable compute, storage, and power modules.
+- **Sovereignty:** Full control over hardware and the software stack (running `org-agent`).
+- **Aesthetics:** Sleek "Hi-Fi" industrial design.
+- **Multimodality:** Integration of SDR, AV, and specialized processors.
+
+** 3. Success Criteria
+*** TODO Inter-module communication standard specification
+*** TODO Power delivery backplane design (schematic)
+*** TODO Compute module (Arm/RISC-V) software stack definition
+*** TODO 10-inch form factor industrial design stubs
+
+* Phase B: Blueprint (PROTOCOL)
+:PROPERTIES:
+:STATUS: SIGNED
+:END:
+
+** 1. Architectural Intent
+Interfaces for hardware status monitoring and inter-module orchestration. Source of truth is the physical hardware spec and the kernel telemetry.
+
+** 2. Semantic Interfaces
+#+begin_src lisp
+(defun server-module-status (module-id)
+  "Retrieves health and load telemetry from a specific hardware module.")
+
+(defun server-shutdown-sequence ()
+  "Gracefully powers down all modules via the backplane controller.")
+#+end_src
+
+* Phase D: Build (Implementation)
+Implementation involves PCB designs (KiCad), CAD models (FreeCAD), and driver software.
+
+** Hardware Logic (Software Component)
+#+begin_src lisp
+;; Implementation of hardware monitoring stubs
+#+end_src
+
+* Phase E: Chaos (Verification)
+Verification involves thermal stress testing, power-fail recovery simulation, and bus protocol integrity audits.
