We are migrating from GitHub to Tangled, a decentralized code hosting platform built on AT Protocol. 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)
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.
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

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.

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".
Claude native binary: switched to native binary (225MB ELF, no Node.js needed)
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

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>

Adding a Piece#

Every piece is a single .mjs (JS) or .lisp (KidLisp) file in system/public/aesthetic.computer/disks/. Scaffold from the template:

npm run new <slug> "one-line description"

Header convention — the docs auto-scan reads lines 1–2:

// 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 /<slug> 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. Curated entries always win over the auto-scan.

See WRITE-A-PIECE.md for the end-user source / publish flow and CLAUDE.md for the full piece API surface.

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

Piece-Log Debugging (client-side errors)#

Every piece load gets a fresh pieceId and a 2-second-batched wrapper around console.log / warn / error / info is installed in system/public/aesthetic.computer/lib/disk.mjs (~line 970). Events are POSTed to /api/piece-log (netlify/functions/piece-log.mjs) and stored in MongoDB in the piece-runs collection with phases start / log / error / complete.

This is the primary debug channel for problems you can't reproduce locally — silent synth failures, "worked for me but not for the user" bugs, hydration issues on specific hosts. Each record carries:

pieceId, slug, bootId, userAgent, host, geo (from CF headers)
events[] — the captured console output with {level, at, elapsed, message}, last 500 per run
error — if the piece crashed, {message, stack}
summary — on clean exit, {duration, ...}

Inspecting from the CLI (SSHes to lith, runs system/backend/piece-logs-cli.mjs against the deployed env):

ac-piece-logs notepat                   # recent 20 runs of a slug
ac-piece-logs-events notepat --since 30 # include console events, last 30 min
ac-piece-logs-errors                    # status=error runs in the last hour
ac-piece-logs-grep "drumMode"           # full-text search across captured events
ac-piece-logs-json --slug notepat | jq  # raw JSON for scripting

The CLI ships with every fish lith/deploy.fish. If you add new telemetry, bump the payload in disk.mjs and the phase handler in netlify/functions/piece-log.mjs; no schema migration needed (MongoDB collection is schemaless).

Pulling Chat Messages (clock / system channels)#

Chat lives in MongoDB. Each channel is a separate collection:

chat-system — the main chat piece (/chat)
chat-clock — the laer-klokken / r8dio chat piece (connects via client.connect("clock") in disks/laer-klokken.mjs)

Public read endpoint: /api/chat-messages (GET, 2-min Redis cache):

# Latest 100 clock-channel messages as chronological JSON (oldest → newest)
curl -s "https://aesthetic.computer/api/chat-messages?instance=clock&limit=100" | jq

# Just handle + text
curl -s "https://aesthetic.computer/api/chat-messages?instance=clock&limit=100" \
  | jq -r '.messages[] | "\(.when)  \(.from)  |  \(.text)"'

# Filter by sender or URL pattern (e.g. YouTube links from @prutti)
curl -s "https://aesthetic.computer/api/chat-messages?instance=clock&limit=100" \
  | jq -r '.messages[]
            | select((.from == "@prutti") or (.text | test("youtu\\.?be|youtube\\.com"; "i")))
            | "\(.when)  \(.from)  |  \(.text)"'

Query params:

instance — system (default) or clock. Any other value hits chat-system.
limit — up to 100 (over 100 returns HTTP 400). Sort is when descending, then reversed to chronological before returning.

Response shape: { instance, count, messages: [{ id, from, text, when, hearts }], nextBefore }. from is resolved to @handle via the @handles collection, falling back to "anon" for unclaimed user ids. hearts joins the shared hearts collection (type: "chat-<instance>"). nextBefore is the oldest when in the page, ready to hand back as before= for the previous page.

Going back further than 100 messages — pass before=<ISO> to walk back (or use nextBefore from the previous response):

# All @prutti YouTube links in the clock channel, paginating back
cursor=""
while true
    set url "https://aesthetic.computer/api/chat-messages?instance=clock&limit=100"
    test -n "$cursor"; and set url "$url&before=$cursor"
    set page (curl -s $url)
    test (echo $page | jq '.count') -eq 0; and break
    echo $page | jq -r '.messages[]
      | select(.from == "@prutti" and (.text | test("youtu"; "i")))
      | "\(.when)  \(.text)"'
    set cursor (echo $page | jq -r '.nextBefore')
end

Full docs and curl/JS/Python examples live at /api/chat-messages on api.aesthetic.computer (served by system/netlify/functions/api-docs.mjs).

If you ever need raw Mongo access (deleted messages, admin edits, heavier aggregations), go direct from lith:

# On lith (or any machine with backend creds loaded):
ac-host                                          # pick lith
# then in the ssh session:
cd aesthetic.computer/system
node -e '
  import("./backend/database.mjs").then(async ({ connect }) => {
    const { db, disconnect } = await connect();
    const rows = await db.collection("chat-clock")
      .find({ when: { $lt: new Date("2026-04-22T00:00:00Z") } })
      .sort({ when: -1 }).limit(500).toArray();
    console.log(JSON.stringify(rows, null, 2));
    await disconnect();
  });
'

When adding before pagination, update the TODO at the top of chat-messages.mjs and bump the cache key so stale entries don't mask the new param.

Claude on ac-native — A Claude Code CLI binary is bundled into the initramfs at /bin/claude, pre-authenticated with @jeffrey's credentials. When running inside ac-native it has the same repo view as everywhere else, plus direct access to the real hardware.

Hardware Probing on ac-native#

When the onboard Claude is debugging a device (missing speakers, WiFi, trackpad, etc.) the below surfaces are always available without needing a separate diagnostic build. Probe from the prompt, a piece, or a shell — whatever fits the task.

Boot-time logs (USB pulled out then inspected on a host)#

/mnt/pre-launch.log — init script's full probe dump: GPU nodes, block devices, net ifaces, rfkill state, PCI devices with bound drivers, ACPI codecs, sound PCM names, GPIO chips + descriptor consumers, ASoC debugfs, MAX98357A amp state, and a subset of the running kernel config via /proc/config.gz (CONFIG_IKCONFIG=y).
/mnt/kmsg.log — persistent cat /dev/kmsg for the entire boot session. Grep for any driver probe, dev_dbg, or warning.
/mnt/ac-native-stderr.log — ac-native's ALSA init trace (device opened, mixer enumeration, volume sets, XRUN count).
/mnt/flash-last.log — flash-thread telemetry from the last OTA.

Runtime probing (piece APIs)#

system.audio.listPcms() → array of {device, card, num, id, name}. Skips HDMI. active: true marks the PCM ac-native's main audio thread opened.
system.audio.testPcm(device, freq_hz, duration_ms, volume) — plays a short sine wave on an arbitrary ALSA device in a detached thread. Used by the speaker piece to find which PCM actually drives the onboard speakers vs headphone jack vs HDMI. Piece source: speaker.mjs.
system.firmware.{available, board, biosVersion, install} — machines running MrChromebox coreboot can reflash from os.mjs's firmware panel (gated behind /dev/mtd0 + bios_vendor=coreboot).

Live sysfs hotspots#

/proc/asound/card0/pcm*p/info — per-PCM id/name. On SOF: pcm0p is usually "Speakers", pcm1p "Headset", pcm2-4p are HDMI.
/sys/bus/gpio/devices/ + /sys/kernel/debug/gpio — list every GPIO chip + which consumer holds which pin. gpio-* | sdmode shows the MAX98357A speaker-enable line.
/sys/bus/pci/devices/<BDF>/driver — symlinks to each PCI device's driver. drv=NONE means the driver isn't bound (either missing config, missing firmware file, or missing ACPI device match).
/sys/bus/acpi/devices/<HID>:NN/physical_node/driver — same but for ACPI-enumerated devices (audio codecs, embedded controller, pinctrl, etc).
/proc/config.gz — zcat /proc/config.gz | grep CONFIG_FOO= tells you definitively whether a config survived make olddefconfig.

Build-time canaries#

docker-build.sh verifies six critical driver symbols (jsl_pinctrl_ acpi_match, max98357a_sdmode_event, rt5682_i2c_probe, i2c_dw_prepare_clk, …) are linked into vmlinux via nm. When a new config toggles on, a hash sentinel wipes the matching subsystem's object files so kbuild actually rebuilds them. If your build fails at "BUILD SANITY: critical driver symbols missing", wipe the persistent docker volume: docker volume rm ac-os-kbuild.
