We'd love to hear from you. --- ## Context Resolution Order Interpret names and requests in this order unless the user explicitly points elsewhere: 1. **Our seat / local fleet** — machines, displays, prompt rocks, host tooling, and the immediate development environment. Names such as `panda`, `chicken`, `neo`, and `blueberry` mean machines first. 2. **Aesthetic Computer** — this monorepo, its pieces, services, and production system. 3. **Client context** — client infrastructure or projects only when the conversation makes that context clear; resolve their details through `aesthetic-computer-vault`. Do not interpret a known machine name as an Aesthetic Computer piece until the seat/fleet meaning has been ruled out. ## Front Door 359 built-in pieces (341 JS + 18 KidLisp), ~90 API endpoints.
2812 registered handles, 265 user-published pieces, 4429 paintings, 16779 KidLisp programs, 18107 chat messages, 20 prints ordered.

Our repo now lives on a self-hosted knot at `knot.aesthetic.computer` under the same ATProto identity (`did:plc:k3k3wknzkcnekbnyde4dbatz`) that powers our PDS, user handles, and federated content. GitHub will be maintained as a read-only mirror during the transition. --- ## 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 + geckos.io UDP). Hosted on its own DigitalOcean VPS; deployed via `fish session-server/deploy.fish` (sshes to the box, `git pull` from github main, restart node `session.mjs`). Houses `arena-manager.mjs` which is the authoritative pmove + snapshot pipeline for `disks/arena.mjs`. - `lith/` — Production monolith deploy (Express + Caddy on a DigitalOcean VPS, pulled from the tangled knot `git@knot.aesthetic.computer:aesthetic.computer/core` via `lith/deploy.fish`). Express adapts the handlers in `system/netlify/functions/` as routes — the `netlify/functions/` path is historical; Netlify is no longer the host. - `lith/mirror/` — knot↔github bidirectional mirror (systemd timer, every 60s). Lets us push to knot only while still letting downstream consumers (session-server VPS, mirrors) pull from github. - `help/bridge/` — Local Express bridge on @jeffrey's macbook that spawns the host `claude` CLI and streams it as SSE; reached publicly through `help.aesthetic.computer` via the existing droplet proxy + autossh reverse tunnel. Powers the `aa` piece (admin-only phone-side chat with the macbook's claude). Auto-runs under launchd as `computer.aesthetic.aa-bridge` and `computer.aesthetic.aa-tunnel`. - Authentication and data storage **Arena auto-deploy (post-commit hook)** — Any commit on `main` that touches `disks/arena.mjs`, `lib/{arena-world,pmove,cam-doll}.mjs`, `session-server/{arena-manager,session}.mjs`, or `shared/` triggers a paired deploy in the background: 1. push HEAD to knot (`origin`) so lith pulls the right commit 2. `fish lith/deploy.fish` — pulls knot, restarts the monolith 3. wait ~75s for the knot→github mirror 4. `fish session-server/deploy.fish` — VPS pull from github + node restart This is critical because `lib/pmove.mjs` is shared physics: client (lith) and server (session-server) MUST match, otherwise `arena-manager.mjs`'s reconciler will fight the client's prediction and movement glitches. Logs land in `.git/arena-auto-deploy.log`. Set `AC_NO_AUTO_DEPLOY=1` to skip (e.g. while bisecting). **Languages** - `kidlisp/` — KidLisp dialect (Lisp for generative art) - `compiler.mjs` — Parser and compiler - `spec/*.mjs` — Test specs **Desktop (ac-electron/)** - `ac-electron/main.js` — Electron main process: tray, menubar/notepat modes, multi-window orchestration, native bridges, auto-update. - `ac-electron/preload.js` + `webview-preload.js` — Bridges between main process and the AC web client running in the embedded webview. - `ac-electron/renderer/` — Native chrome (preferences, flip-view, notepat overlay) rendered outside the web client. - `npm start` — Run against `https://aesthetic.computer` (prod) or `http://localhost:8888` (dev with `--dev`). - `npm run build:mac` / `build:win` / `build:linux` — electron-builder packaging. - `npm run release:host:mac` — Notarized signed mac build published to `silo.aesthetic.computer/desktop/`. - **File associations:** mp3/wav/flac/ogg/m4a drop on the Dock icon (or onto a running window) opens the `play` piece. A loopback http server (`127.0.0.1:`) streams the file with HTTP Range so scrubbing works. **AC Electron Backlog:** - [x] Drag-and-drop mp3 onto app icon launches `play` piece via loopback streaming server - [ ] Same drop pipeline for paintings (`.png`/`.gif`) → open in `nopaint` - [ ] Same drop pipeline for `.lisp` source → load directly as a piece (`source piece-name`) - [ ] Multi-file drop: queue tracks in `play` as an ad-hoc playlist - [ ] Promote `system.droppedFile` to a generic `system.droppedFiles[]` API so any piece can accept its own MIME types **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. **AC Native Backlog:** - [ ] Per-user wifi credential storage: move hardcoded SSIDs out of JS pieces into per-handle config (e.g. `config.json` or `/mnt/wifi_creds.json` on USB). Each user's build should bundle their saved networks, not @jeffrey's home wifi. - [ ] Wifi cred persistence across OTA updates: saved networks on USB should survive re-flashing. - [ ] Geo-aware greeting: use `geo` piece's IP location for dynamic "enjoy [city]!" instead of hardcoded "Los Angeles". - [x] Claude native binary: switched to native binary (225MB ELF, no Node.js needed) - [x] Claude OAuth: using device-code auth method, loopback interface enabled - [ ] Session log upload to machines: on wifi connect + shutdown, upload ac-native.log to machines API (keyed by machine-id). View live/historical logs per device on machines dashboard. - [ ] Live log streaming: WebSocket pipe from device → machines dashboard for real-time debug - [ ] A/B kernel slots with auto-rollback: if boot doesn't reach "healthy" checkpoint in 60s, swap .prev kernel back - [ ] Terminal: full Unicode font support (bitmap glyphs for box drawing, block elements) - [ ] KidLisp GPU compositing: render effects on GPU buffer, recompose with CPU renderer **Host Tooling (slab/)** — @jeffrey's macOS host, not a deployed service - **Unipointer** (`slab/deskflow-handoff/UNIPOINTER.md`) — canonical identifier for the Fuser seat's one logical pointer. Neo and Blueberry can exchange the physical Deskflow controller role without changing the unipointer's active machine or display-local position. Code and agents should use the literal identifier `unipointer` and state-record kind `unipointer-state`; every fleet host exposes `~/.local/bin/unipointer` for versioned JSON state. - `slab/menubar-swift/` — native Swift menubar daemon (launchd `computer.slab.menubar`). Shows live Claude-session status, themes each Terminal.app/iTerm2 window by session state (working/awaiting/complete), tiles all windows into one grid, tints the desktop, and serves passphrases over a unix socket. Built + installed locally with `slab/menubar-swift/install.sh` (`swift build -c release` → universal arm64+x86_64 binary → app bundle + launchd agent); there is no remote deploy. - **Tiling auto-fits the type:** `tileNow` sizes each Terminal window's font to the grid (Far/Near/Tiny modes) and drives `View ▸ Default Font Size` per window so a live window actually adopts it — a per-window zoom otherwise silently overrides the profile font and is invisible to AppleScript. Floors keep it legible (Far 10 / Near 9 / Tiny 8). iTerm2 has no AppleScript font property, so it tiles by bounds only. - **Prompt rocks** (`slab/menubar-swift/Sources/SlabMenubar/PromptSigilOverlay.swift`) — the tumbling little stones parked at the top-right of each terminal window, one per live Claude session. Each rock is a 3D sigil rendered from the session's `sessionId + prompt` seed (so it re-forms when the session moves to a new prompt), lit by a shared global sun that tracks local time of day, wearing a pet name in bubble lettering. Its *motion* is the status channel — spin speed and direction encode working/awaiting/complete; being read by a peer makes it blink and rattle. Hovering one reveals a bubble summarizing the prompt (a cached one-line `claude -p haiku` inference). They're borderless click-through `.floating` windows, so hit-testing has to check occlusion by hand: a rock only answers the pointer while it's on screen *and* its terminal is still the topmost normal window under the cursor. - **Prompt rocks MCP** (`slab/bin/prox-mcp.mjs`, registered as `prox` in `.mcp.json`) — an MCP over the fleet handle ledger (`Ledger.swift`; `~/.config/slab/ledger/{local,peers/*}.json`, served per-machine on tailnet-only `:5252`) so any agent can `prox_list` every live session across machines, `prox_find` a `host:name` reference (e.g. `neo:regif`) to its status/subject/cwd/seed, `prox_poke` one (`POST /poke` → the target rock blinks + rattles), and `prox_launch` a new Claude/Codex Terminal on a prompt host. Launch is deliberately not a remote shell: the target accepts only those two fixed agents, a bounded prompt, and a cwd beneath that user's home. `prox_close` reads the session marker for tty+pid and closes locally only (refuses the calling session). This is how a `machine:promptname` handle resolves without an SSH crawl. - **Loopboy** (`~/.config/slab/loopboy.json`, surfaced in the Slab menubar) — the primary client-loop interface. Each route maps one private iMessage contact key to one stable local prox session; new inbound messages poke and optionally wake only that contact's rock. Loopboy never replies by itself. Armed rocks spin faster, glow pink, and identify themselves as Loopboy on hover. Create or replace a route with `prox_bind_notification(handle, contact)`. - **Paper MCP / `/papers` stack** (`slab/bin/paper-mcp.mjs`, registered as `paper`) — “use the papers stack,” “use `/papers`,” and similar requests name the studio's scholarly publishing workflow, not merely a request to export or prettify a PDF. Begin by consulting [`papers/SCORE.md`](papers/SCORE.md), the public Platter index, relevant sub-platters, prior papers and bibliographies, and the underlying code/data/evidence. Unless the user names another mill lane, shape the result as an archival/arXiv-style LaTeX paper: title/byline/date, abstract, problem and context, related work, system or method, implementation, evidence/evaluation, ethics/privacy/limitations, conclusion, references, numbered/captioned figures and tables, and reproducible source/assets. Briefings, decks, cards, dossiers, and visual reports are distinct lanes and require explicit intent or strong task evidence. The MCP is the transport/build/inspection layer: `paper_list`/`paper_find` locate precedent, `paper_read` supports the Platter consult, `paper_build` runs XeLaTeX or Tectonic, `paper_figure_table_qa_check` supports mandatory visual inspection, and `paper_open` raises the result through `slab-pdf`. The shared loopback daemon is `:7777`; `toolchain/mcp/install-daemons.sh` registers it for Claude and Codex. A build may pass `notifyHandle` to return its PDF to the originating rock through `prox_artifact_ready`. - `slab/bin/ac-passphrase` — pinentry-free secret fetch from the daemon (see Development Environment below). **Other Projects** - `tezos/` — NFT/blockchain experiments - `grab/` — Media utilities - `feed/` — RSS/content feeds ### How to Run **Start the dev server:** ```bash npm start # Visit http://localhost:8888 ``` **Run all tests:** ```bash npm test ``` **Run KidLisp tests:** ```bash npm run test:kidlisp # Or filter: npm run test:kidlisp -- --filter= ``` ### Adding a Piece Every piece is a single `.mjs` (JS) or `.lisp` (KidLisp) file in [`system/public/aesthetic.computer/disks/`](system/public/aesthetic.computer/disks/). Scaffold from the template: ```bash npm run new "one-line description" ``` **Header convention** — the docs auto-scan reads lines 1–2: ```js // Name, YY.MM.DD.HH.MM // One-line description shown in `list` and prompt autocomplete. ``` **Lifecycle exports** (all optional except whichever ones you need): `boot`, `paint`, `sim`, `act`, `leave`. Export `meta()` to opt the piece **into** `list` and prompt autocomplete — omit it and the piece stays reachable at `/` but hidden from indexes (good for drafts). **Curating the entry** (richer `desc`, `colon` params/`examples`, force `hidden: true`, or override an auto-entry): edit the `pieces` map in [`system/netlify/functions/docs.js`](system/netlify/functions/docs.js). Curated entries always win over the auto-scan. See [`WRITE-A-PIECE.md`](WRITE-A-PIECE.md) for the end-user `source` / `publish` flow and [`CLAUDE.md`](CLAUDE.md) for the full piece API surface. ### Development Environment The global environment model lives in [`ENVIRONMENT.md`](ENVIRONMENT.md). Resolve the active environment before applying editor- or host-specific instructions. An ordinary Claude Terminal session on macOS is `terminal-macos`; it should use its local shell directly and should not describe Emacs/fishy as a missing bridge or fallback. #### `[environment: emacs]` Emacs Terminal Buffers When Emacs is the active environment, use Emacs MCP tools (`mcp_emacs_*`) and the named terminal buffers. The `🐟-fishy` buffer is the primary shell: - `🐟-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 (Emacs environment only):** 1. Use `mcp_emacs_emacs_switch_buffer` to switch to `🐟-fishy` 2. Use `mcp_emacs_emacs_send_keys` to send the command 3. Send newline to execute **Fish Shell Commands (`ac-*` helpers):** #### Emacs & Development Environment - `ac-aesthetic` — Connect to aesthetic emacs UI (alias for `aesthetic-now`) - `ac-emacs-restart` — Kill and restart emacs daemon - `ac-emacs-full-restart` — Restart emacs and reconnect UI - `ac-emacs-kill` — Kill emacs daemon - `ac-emacs-status` — Check emacs daemon health - `ac-emacs-logs` — View emacs logs - `ac-emacs-health-check` — Verify emacs config loaded correctly - `ac-restart` — Restart all AC tabs/processes (calls emacs `ac-restart`) - `ac-crash-diary` — View emacs crash log - `ac-emacs-crash-monitor` — Background process that monitors emacs #### Core Development - `ac-artery` — Start artery development server - `ac-artery-dev` — Start artery in dev mode - `ac-site` — Start site server - `ac-session` — Start session server - `ac-url` — Get local tunnel URL - `ac-views` — View stats - `ac-watch` — Watch and rebuild (alias for `npm run watch`) - `ac-repl` — Start REPL #### KidLisp Tools - `ac-st` — KidLisp source tree viewer (`ac-st cow`, `ac-st $cow`, `ac-st cow --source`) #### Testing & Debugging - `ac-test-tabs` — Test tab functionality - `ac-diagnose` — Run diagnostics - `ac-profile-start` — Start performance profiling - `ac-profile-stop` — Stop performance profiling - `ac-profile-report` — Generate profile report - `ac-watch-cpu` — Monitor CPU usage - `ac-dev-log` — View development logs - `ac-dev-logs` — View all dev logs - `ac-dev-log-clean` — Clean old logs - `ac-dev-log-new` — Create new log - `ac-piece-logs [slug]` — Recent piece-run telemetry (see [Piece-Log Debugging](#piece-log-debugging-client-side-errors)) - `ac-piece-logs-events [slug]` — Include captured `console.log`/`warn`/`error` output - `ac-piece-logs-errors` — Runs with `status=error` in the last 60 minutes - `ac-piece-logs-grep ` — Search console-event text across recent runs #### Deployment & Distribution - `ac-pack` — Package for distribution - `ac-unpack` — Unpack distribution - `ac-ship` — Deploy/ship changes - `ac-keep` — Save state/backup - `ac-keeps` — List saved states - `ac-keep-test` — Test keep functionality #### Media & Recording - `ac-tv` — TV mode - `ac-record` — Start recording - `ac-pix` — Image utilities - `ac-media` — Media server #### Services & Infrastructure - `ac-servers` — Start all servers - `ac-tunnel` — Start tunnel - `ac-chat-system` — Start chat system - `ac-chat-sotce` — Start sotce chat - `ac-chat-clock` — Start clock chat - `ac-stripe-print` — Stripe print service - `ac-stripe-ticket` — Stripe ticket service - `ac-logger` — View lith backend logs (the handlers living under `system/netlify/functions/` run under lith's Express; the name is legacy) - `ac-oven` — Oven service - `ac-offline` — Offline mode #### Authentication & Tokens - `ac-login` — Login to AC - `ac-token` — Manage auth tokens - `slab/bin/ac-passphrase
