-For hosted deployment, another repo such as `../extremist-software` imports `noisebell.nixosModules.default`. That host repo provides deployment-specific values like domains, ports, and the Pi address, while the Noisebell module itself points `agenix` at the encrypted files in `secrets/` and consumes the decrypted runtime files on the target machine.

 # Pi
 
-Rust service and deployment workflow for the Raspberry Pi at Noisebridge.
+Rust service and NixOS config for the Raspberry Pi at Noisebridge. Reads a magnetic door sensor via GPIO, serves the current state over HTTP, and pushes changes to the cache service.
 
-The current recommended setup is:
+Runs NixOS with Tailscale for remote access and agenix for secrets.
 
-1. run Raspberry Pi OS Lite on the Pi
-2. keep the Pi itself free of Nix
-3. build a static `aarch64` Noisebell binary on your laptop with Nix
-4. copy the binary, secrets, and systemd service to the Pi over SSH
+## How it works
 
-This avoids the Raspberry Pi Zero 2 W NixOS boot issues while still keeping the application build reproducible.
+The service watches a GPIO pin for rising/falling edges with a configurable debounce. When the door state changes, it:
 
-## What stays on Raspberry Pi OS
+1. Updates in-memory state (atomics)
+2. POSTs `{"status": "open", "timestamp": ...}` to the cache service with a Bearer token
+3. Retries with exponential backoff on failure
 
-- bootloader
-- kernel
-- firmware
-- Wi-Fi and local networking
-- SSH base access
-- Tailscale package/runtime
-- Avahi package/runtime
+On startup it also syncs the initial state.
 
-## What Nix manages
+## Setup
 
-- building a static `noisebell` binary for `aarch64-linux`
-- the exact app binary you deploy
-- encrypted secrets in the repo
-- repeatable deployment from your laptop
+### Prerequisites
 
-## Initial Pi OS setup
+If you're building on an x86_64 machine, you need binfmt emulation for aarch64. On NixOS, add this to your system config and rebuild:
 
-### 1. Flash Raspberry Pi OS Lite
-
-```sh
-curl -L "https://downloads.raspberrypi.org/raspios_lite_arm64_latest" | xz -d -c | sudo dd of=/dev/sdb bs=16M conv=fsync status=progress && sync
+```nix
+boot.binfmt.emulatedSystems = [ "aarch64-linux" ];
 ```
 
-### 2. Configure the flashed SD card
+### 1. Flash the SD card
 
-Configure it for:
-
-- Wi-Fi on `Noisebridge`
-- SSH enabled
-- serial enabled if you want a recovery console
-
-The helper script is:
+Preferred: one command builds the bootstrap image, writes it to the SD card, and installs the
+bootstrap agenix identity onto the boot partition so the full Pi system can come up on first boot:
 
 ```sh
-sudo scripts/configure-pios-sd.sh /run/media/jet/bootfs /run/media/jet/rootfs
+nix run .#flash-pi-sd -- /dev/sdX
 ```
 
-This setup expects SSH key login for user `pi`; it does not configure a password.
+This bootstrap image already includes the normal Noisebell service, Tailscale, and the Pi config.
 
-### 3. Boot the Pi and verify SSH
-
-After boot, verify SSH works:
+Manual build if you need it:
 
 ```sh
-ssh pi@noisebridge-pi.local
+nix build .#nixosConfigurations.bootstrap.config.system.build.sdImage
+dd if=result/sd-image/*.img of=/dev/sdX bs=4M status=progress
 ```
 
-## Add the Pi host key to age recipients
+Boot the Pi. It connects to the Noisebridge WiFi automatically.
 
-The deploy flow decrypts secrets locally on your laptop, but the Pi host key should still be a recipient for the Pi-facing secrets so the repo stays accurate.
+### 2. SSH host key
 
-Grab the Pi host key:
+Grab the key and add it to `secrets/secrets.nix`:
 
 ```sh
 ssh-keyscan noisebridge-pi.local 2>/dev/null | grep ed25519
 ```
 
-Add that key to `secrets/secrets.nix` for:
+```nix
+# secrets/secrets.nix
+let
+  pi = "ssh-ed25519 AAAA...";
+in
+{
+  "api-key.age".publicKeys = [ pi ];
+  "inbound-api-key.age".publicKeys = [ pi ];
+  "tailscale-auth-key.age".publicKeys = [ pi ];
+}
+```
 
-- `pi-to-cache-key.age`
-- `cache-to-pi-key.age`
-- `tailscale-auth-key.age`
+### 3. Create secrets
 
-Then refresh recipients if needed:
+```sh
+cd secrets
+agenix -e api-key.age            # key for POSTing to the cache
+agenix -e inbound-api-key.age    # key the cache uses to poll us
+agenix -e tailscale-auth-key.age # tailscale auth key
+```
+
+### 4. Bootstrap agenix identity
+
+The Pi uses a dedicated bootstrap age identity stored at `/boot/noisebell-bootstrap.agekey` to
+decrypt its runtime secrets, so first boot does not depend on the machine's freshly generated SSH
+host key.
+
+To refresh recipients after changing `secrets/secrets.nix`:
 
 ```sh
 cd secrets
 agenix -r
 ```
 
-## Edit secrets
+If you use `nix run .#flash-pi-sd -- /dev/sdX`, this file is installed automatically.
+
+To install the bootstrap identity manually onto a flashed card before first boot:
 
 ```sh
 cd secrets
-agenix -e pi-to-cache-key.age
-agenix -e cache-to-pi-key.age
-agenix -e tailscale-auth-key.age
+agenix -d bootstrap-identity.age > /boot/noisebell-bootstrap.agekey
+chmod 600 /boot/noisebell-bootstrap.agekey
 ```
 
-These stay encrypted in git. The deploy script decrypts them locally on your laptop and copies the plaintext files to the Pi as root-only files.
+### 5. SSH access
 
-## Deploy to Raspberry Pi OS
+Add your public key to `configuration.nix`:
 
-From your laptop:
+```nix
+users.users.root.openssh.authorizedKeys.keys = [
+  "ssh-ed25519 AAAA..."
+];
+```
+
+### 6. Deploy
+
+After first boot, the Pi should already be running the normal service stack from the flashed image.
+Use this only for later updates:
 
 ```sh
-scripts/deploy-pios-pi.sh pi@noisebridge-pi.local
+nixos-rebuild switch --flake .#pi --target-host root@noisebell
 ```
 
-If you only know the IP:
+## Configuration
 
-```sh
-scripts/deploy-pios-pi.sh pi@10.21.x.x
-```
+Options under `services.noisebell` in `flake.nix`:
 
-That script:
-
-1. builds `.#packages.aarch64-linux.noisebell-static` locally
-2. decrypts the Pi-facing secrets locally with `agenix`
-3. uploads the binary and secrets to the Pi
-4. installs Tailscale and Avahi if needed
-5. writes `/etc/noisebell/noisebell.env`
-6. installs `noisebell.service`
-7. enables and starts the service
-8. runs `tailscale up` with the decrypted auth key
-
-## Files written on the Pi
-
-The deploy script creates:
-
-- `/opt/noisebell/releases/<timestamp>/noisebell`
-- `/opt/noisebell/current` -> current release symlink
-- `/etc/noisebell/pi-to-cache-key`
-- `/etc/noisebell/cache-to-pi-key`
-- `/etc/noisebell/tailscale-auth-key`
-- `/etc/noisebell/noisebell.env`
-- `/etc/systemd/system/noisebell.service`
-
-All secret files are root-only.
-
-## Tailscale
-
-Tailscale is kept on Raspberry Pi OS rather than NixOS.
-
-The deploy script:
-
-- installs the Tailscale package if missing
-- enables `tailscaled`
-- runs `tailscale up --auth-key=... --hostname=noisebridge-pi`
-
-So Tailscale stays part of the base OS, while its auth key is still managed as an encrypted `age` secret in this repo.
-
-## Later updates
-
-Normal iteration is just rerunning the deploy script:
-
-```sh
-scripts/deploy-pios-pi.sh pi@noisebridge-pi.local
-```
-
-That rebuilds the binary locally, uploads a new release, refreshes secrets, and restarts the service.
-
-## Service configuration
-
-The deployed service uses these environment variables:
-
-| Variable | Default | Description |
+| Option | Default | Description |
 |---|---|---|
-| `NOISEBELL_GPIO_PIN` | `17` | GPIO pin number |
-| `NOISEBELL_DEBOUNCE_SECS` | `5` | Debounce delay in seconds |
-| `NOISEBELL_PORT` | `80` | HTTP server port |
-| `NOISEBELL_ENDPOINT_URL` | required | Webhook URL to POST state changes to |
-| `NOISEBELL_RETRY_ATTEMPTS` | `3` | Webhook retry count |
-| `NOISEBELL_RETRY_BASE_DELAY_SECS` | `1` | Exponential backoff base delay |
-| `NOISEBELL_HTTP_TIMEOUT_SECS` | `10` | Outbound request timeout |
-| `NOISEBELL_BIND_ADDRESS` | `0.0.0.0` | HTTP bind address |
-| `NOISEBELL_ACTIVE_LOW` | `true` | Low GPIO = door open |
+| `endpointUrl` | required | Webhook URL to POST state changes to |
+| `apiKeyFile` | required | Outbound API key file (agenix secret) |
+| `inboundApiKeyFile` | required | Inbound API key file for GET auth |
+| `gpioPin` | `17` | GPIO pin number |
+| `debounceSecs` | `5` | Debounce delay in seconds |
+| `port` | `8080` | HTTP server port |
+| `retryAttempts` | `3` | Webhook retry count |
+| `retryBaseDelaySecs` | `1` | Exponential backoff base delay |
+| `httpTimeoutSecs` | `10` | Outbound request timeout |
+| `bindAddress` | `0.0.0.0` | HTTP bind address |
+| `activeLow` | `true` | Low GPIO = door open (depends on wiring) |
+| `restartDelaySecs` | `5` | systemd restart delay on failure |
+| `watchdogSecs` | `30` | systemd watchdog timeout |
 
 ## API
 
 All endpoints require `Authorization: Bearer <token>`.

-When `extremist-software` builds a system using the Noisebell flake input, Nix uses the checked-out flake source for that input. The module points `agenix` at encrypted files inside that Noisebell source tree, such as `${inputs.noisebell}/secrets/discord-token.age`. At activation time `agenix` decrypts them locally on the target host into runtime paths like `/run/agenix/noisebell-discord-token`. The service modules then read those local decrypted files when systemd starts them.
