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)

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 `opencortex`).
• 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)

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

(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.")

Phase D: Build (Implementation)

Implementation involves PCB designs (KiCad), CAD models (FreeCAD), and driver software.

Hardware Logic (Software Component)

;; Implementation of hardware monitoring stubs

Phase E: Chaos (Verification)

Verification involves thermal stress testing, power-fail recovery simulation, and bus protocol integrity audits.
