#+TITLE: SKILL: Lisp Machine Bootstrap (Universal Literate Note)
#+ID: skill-lisp-machine-bootstrap
#+STARTUP: content
#+FILETAGS: :hardware:lisp:sovereignty:fpga:psf:

* Overview
The *Lisp Machine Bootstrap* project is the "Endgame" of the PSF. It aims to eliminate the "Unix/C Tax" by building a hardware-native Lisp machine where CAR, CDR, and CONS are primitive gates. This ensures ultimate digital sovereignty and a provably secure, homoiconic environment.

* Phase A: Demand (PRD)
:PROPERTIES:
:STATUS: FROZEN
:END:

** 1. Purpose
Define the requirements for a hardware environment optimized for Lisp and user sovereignty.

** 2. User Needs
- *Hardware-Native Lisp:* ISA designed for list processing efficiency.
- *Tagged Memory:* Hardware-level safety preventing memory corruption.
- *Bootstrapping Path:* Progression from Soft Machine (Linux) to Sovereign Silicon (ASIC).
- *Transparency:* Every gate and instruction must be introspectable and documented.

** 3. Success Criteria
*** TODO Research existing Lisp-on-FPGA implementations (Openora, etc.)
*** TODO Define minimum hardware-native Lisp ISA (Instruction Set Architecture)
*** TODO Draft CLOSOS-style Virtual Machine specification
*** TODO FPGA Implementation: Verilog/VHDL skeleton synthesis

* Phase B: Blueprint (PROTOCOL)
:PROPERTIES:
:STATUS: SIGNED
:END:

** 1. Architectural Intent
The protocol defines the interface between the high-level Lisp image and the low-level ISA/VM.

** 2. Semantic Interfaces
#+begin_src lisp
(defun isa-dispatch (instruction opcode)
  "Simulates the hardware dispatch of a Lisp-native instruction.")

(defun memory-tag-audit (address)
  "Verifies the hardware tag of a specific memory word.")
#+end_src

* Phase D: Build (Implementation)
Current focus is on research and simulation (Phase 1: Soft Machine).

** Simulation Interface
#+begin_src lisp
;; Soft machine simulator stubs
#+end_src

* Phase E: Chaos (Verification)
Verification will occur via FPGA synthesis reports and VM regression tests.
