Back Door

Architecture

Frontend (system/)

system/public/aesthetic.computer/ — Web client (Canvas + WebGL)
- bios.mjs — Core runtime, loads pieces
- boot.mjs — System initialization
- disk.mjs — Piece loader and lifecycle
- disks/*.mjs — Individual pieces (programs)
- lib/*.mjs — Shared libraries and utilities

Backend

session-server/ — Real-time multiplayer (Socket.io)
Netlify deployment for static assets
Authentication and data storage

Languages

kidlisp/ — KidLisp dialect (Lisp for generative art)
- compiler.mjs — Parser and compiler
- spec/*.mjs — Test specs

Desktop

ac-electron/ — Electron wrapper for native apps

Bare Metal OS (fedac/native/)

ac-os build — Full build: binary → initramfs → kernel (produces build/vmlinuz)
ac-os flash — Build + flash to USB
ac-os upload — Build + upload OTA release (always rebuilds — never uploads stale kernels)
ac-os flash+upload — Build + flash + upload
Important: The kernel embeds the git hash and build name at compile time. upload without build would serve a stale kernel. The ac-os script enforces a full rebuild before every upload.

How to Run

Start the dev server:

npm start
# Visit http://localhost:8888

Run all tests:

npm test

Run KidLisp tests:

npm run test:kidlisp
# Or filter: npm run test:kidlisp -- --filter=<spec-name>

Development Environment

Terminal Workflow (IMPORTANT):

Use Emacs MCP + fishy terminal for all command execution
DO NOT use Bash tool for running commands - use fishy via Emacs MCP instead
The fishy terminal (🐟-fishy) is the primary shell for all development commands

Emacs Terminal Buffers: The development environment uses Emacs with named terminal buffers. Use Emacs MCP tools (mcp_emacs_*) to interact with them:

🐟-fishy — Main fish shell (use this for all commands!)
🌐-site — Site/web server logs
📋-session — Session server logs
🧪-kidlisp — KidLisp test runner
🔴-redis — Redis logs
📊-top — System monitoring
🚇-tunnel — Tunnel logs
(See AGENTS.md.backup for full list)

How to run commands in fishy:

Use mcp_emacs_emacs_switch_buffer to switch to 🐟-fishy
Use mcp_emacs_emacs_send_keys to send the command
Send newline to execute

Host Access (Docker)

When running inside a Docker container on Jeffrey's MacBook (or any local Docker host), SSH to the host machine via:

ssh jas@host.docker.internal

"SSH into my macbook" or "SSH into my host" means: connect to host.docker.internal from within the container
ac-host lists all machines from vault/machines.json and can SSH to them
The host machine resolves via host.docker.internal — do NOT use the LAN IP from machines.json when running in Docker

Other Tools

ac-host — List machines, SSH connection info
ac-cdp-tunnel — CDP tunnel
ac-cdp-status — CDP status
ac-extension — Build VSCode extension

Quick Start:

ac-aesthetic          # Connect to development UI
ac-emacs-full-restart # Restart everything
ac-restart            # Restart AC services only

NPM Scripts:

npm run aesthetic — Full-stack local (site + session + services)
npm run site — Client stack only
npm test — Integration tests
npm run test:perf — Performance tests
npm run url — Get local tunnel URL

Notation:

compush — commit, push
