Passepartout Architecture

Passepartout is a self-bootstrapping replacement for the entire personal computing stack — one project, one image, one verified memory graph. Three subsystems compose into a single system:

Verification subsystem — The gate stack that evaluates every proposed action against formal policy. Capability-based authorization. Combines a probabilistic LLM for natural-language reasoning with a deterministic symbolic engine (gate stack, ACL2 prover, Screamer constraint solver) for all security-critical decisions. The gate verifies shell commands, DIDComm messages, and LLM-generated action proposals through the same decision procedure.

Environment subsystem — The Lisp image where editor, browser, shell, and agent coexist. No separate daemons, no IPC boundaries, no trust transitions between components. One address space from which the verification subsystem checks every state mutation.

Roadmap: v2.0 Lish editor + Nyxt browser (Qt/WebKit) → v3.0+ Lisp-native layout & browser → v4.0 in-process LLM → v5.0 tagged RISC-V hardware via TinyTapeout/FPGA → v6.0 world models and true agency.

Social protocol implementation — Self-sovereign DID identity, DIDComm encrypted messaging, Personal Data Store, relay network, compute marketplace, liquid democracy.

All three subsystems operate in the same Lisp address space. All three are verified by the same ACL2 prover. The gate stack that verifies a shell command also verifies a DIDComm message. The distinction between "tool" and "self" dissolves.

Total addressable market: ~$960B/year across cloud, AI, OS, social media, payments, productivity, and compliance.

The business model is the AWS of provable computing: AGPL infrastructure is free, revenue comes from verification appliances, gate rules, certification, namespace registry, hosted PDS, and a compute marketplace. Network effects are positive sum — every instance feeds the regression suite and grows the marketplace.

Strategy and IP:

The protocol overview and advanced integration requirements define how Passepartout's gate stack connects to the social protocol layer. The realistic assessment covers deployment timelines and adoption risks.

The lines that run the modern internet (tens of millions across Google, Meta, Amazon, Apple, Microsoft) are replaced by a single coherent architecture where one gate stack verifies everything and one prover proves everything consistent.
