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)

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)

1. Architectural Intent

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

2. Semantic Interfaces

(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.")

Phase D: Build (Implementation)

Current focus is on research and simulation (Phase 1: Soft Machine).

Simulation Interface

;; Soft machine simulator stubs

Phase E: Chaos (Verification)

Verification will occur via FPGA synthesis reports and VM regression tests.
