#+TITLE: PROJECT: Personal Server Appliance (Universal Literate Note)
#+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 `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)
: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.
