The Pi 4 twin of the Pi 5 build: `rpi4-installed` (in-place rebuild target),
`rpi4-image`, and `packages.aarch64-linux.{sd-image-rpi4,atm-app-rpi4}`, all
through the board-keyed machinery of the previous commit. The shared runtime
is untouched; only the board pair is new.
deploy/nixos/hardware/raspberry-pi-4.nix mirrors raspberry-pi-5.nix line for
line except where the boards differ:
- KMS for the kiosk display is an opt-in on the Pi 4
(`hardware.raspberry-pi."4".fkms-3d`), which also injects the CMA + vc4
device-tree overlays; the Pi 5 gets it by default. Without it X falls back
to the framebuffer and Electron renders in software.
- fkms-3d sets videoDrivers itself, so the module doesn't.
Everything else — extlinux boot, console pinned to tty0 so the GPIO UART is
free for a validator, no-suspend, the ttyValidator{0,1,2} udev symlinks — is
identical by design.
Evaluation-verified only: rpi4-installed/rpi4-image instantiate, and against
rpi5 they differ solely in the expected places (bcm2711 device tree, the two
fkms overlays, the rpiVersion=4 kernel, no clk-rp1 in initrd, machine model
in the env seed). Not yet booted on hardware; the doc says so.
docs/raspberry-pi-setup.md covers both boards — build, flash, first boot +
provisioning via the spire seed, in-place updates, peripherals — since #87
shipped the Pi 5 without one. It replaces a never-committed Pi 4 sketch
(parked on wip/rpi4-sketch) whose flake wiring didn't evaluate and whose
provisioning section predated the pairing seed.

piBaseModules hardcoded the nixos-hardware raspberry-pi-5 module and our
raspberry-pi-5.nix glue, so mkPiInstalled/mkPiImage could only ever produce
a Pi 5. Everything else in the Pi runtime is board-agnostic.
Introduce `piBoards`, keyed by machine model — the parameter already threaded
through both builders — pairing each board's nixos-hardware module with its
glue file, and have piBaseModules look the pair up. Same modules in the same
order for rpi5, so its evaluated configuration is unchanged (compared on 16
app-independent facets: kernel, params, initrd modules, loader, device tree,
video drivers, udev, filesystems, swap, nix settings, sleep targets, service
exec/memory, env seed, sshd). No new board yet — that's the next commit.

`rpi5-installed` previously bundled the sd-image-aarch64 module, so it
was only good for building a flashable image — a `nixos-rebuild switch`
against it (local or the git+ssh remote form) would drag in the image
builder and its image-specific fs wiring. Split it, mirroring the x86
fleet's mkLiveConfig/mkInstalledConfig separation:
- rpi5-installed → in-place rebuild target. Declares the flashed media's
own root fs (NIXOS_SD / FIRMWARE labels), nothing image-specific. This
is what
sudo nixos-rebuild switch --flake \
"git+ssh://forgejo@git.atitlan.io/aiolabs/bitspire.git?ref=<branch>#rpi5-installed"
targets, the aarch64 equivalent of the sintra/douro deploy ritual.
- rpi5-image → same shared runtime + the sd-image builder. Its
system.build.sdImage is the flashable artifact; packages.aarch64-linux
.sd-image-rpi5 now points here.
Shared runtime extracted into piBaseModules/mkPiRuntime; folded the
aiolabs cachix substituter + trusted key into the Pi's nix.settings so a
remote rebuild substitutes the heavy aarch64 closure instead of building
it on the Pi (no max-jobs/timeout watchdog — the Pi 5 can build locally
if it must).
Verified: rpi5-installed evaluates to a valid system toplevel (root fs
present), rpi5-image/sd-image-rpi5 to the .img.zst builder, and x86
sintra-installed is byte-identically unaffected.

Proper aarch64 NixOS target for the DIY Pi 5 build, wired additively so
the x86 fleet path is untouched (both the new Pi sd-image and the
existing sintra-installed still evaluate cleanly):
- nixos-hardware input (raspberry-pi-5 module) for Pi kernel/firmware/GPU.
- aarch64 pkgs + pkgs-unstable + mkAtmApp instances (parallel to x86).
- mkPiConfig: aarch64 nixosSystem reusing the shared configuration.nix +
bitspire-atm service, replicating the installed-config runtime (bitspire
service, first-boot env seed, electron service override, swap). Drops
the x86 fleet machinery for a first bring-up: no determinate/autoUpgrade
(not yet fleet-managed) and no atm-tui (needs an aarch64 package).
- raspberry-pi-5.nix hardware module: extlinux boot, vc4/v3d KMS for X,
primary UART free for a GPIO-wired validator, no-suspend, and stable
/dev/ttyValidator* udev symlinks for USB-serial validator adapters
(Apex 7600 RS-232 via adapter, NV10 USB+).
- nixosConfigurations.rpi5-installed + packages.aarch64-linux.sd-image-rpi5.
BUILD NOTE: the app closure (aarch64 electron/native addons) needs an
aarch64 builder — a native Pi/arm box or `boot.binfmt` qemu emulation on
an x86 host. Config evaluates on x86; it just can't build there.

Lift the USB-variant config (distinct fs labels, nofail /boot, no
growPartition, autoUpgrade off) out of the inline disk-image-batm3-usb
`let` into `nixosConfigurations.batm3-usb`, and build the disk-image from
that same config. Enables in-place app deploys to a running stick via
`nix copy` + `switch-to-configuration` (build the toplevel, copy the
closure, activate) — no reflash, preserving pairing + /var/lib state.

Add a USB-bootable BATM3 disk-image target plus the batm3 hardware
changes that make a dd'd USB stick boot reliably on the Dell 9030 AIO.
flake.nix — new `disk-image-batm3-usb` target:
- Distinct partition labels (nixos-usb / ESP-USB) so stage-1 by-label
resolution can't latch onto an internal SATA drive that already holds
a generic nixos/ESP-labelled install. Post-build mlabel relabels the
ESP FAT volume to ESP-USB (bootloader files untouched; UEFI still
loads /EFI/BOOT/BOOTX64.EFI).
- /boot mounted nofail + short device-timeout: the firmware already
loaded the bootloader before Linux; without nofail a slow/late ESP-USB
enumeration drops to emergency mode with root locked — a dead end.
- NO growPartition/autoResize on the USB image: sfdisk rewriting the
partition table on first boot is the single most bus-stressing write,
and flaky USB bridges drop off the bus mid-rewrite (sfdisk wedges in
uninterruptible D-state and ESP-USB vanishes with the device, so /boot
times out too). Persistent state is a few MB and the image already
ships ~2GB free in root. The internal-SATA disk-image-batm3 keeps
growPartition — a real AHCI SSD won't drop the bus.
- autoUpgrade off (test image, not a managed fleet member).
batm3.nix — USB-boot reliability:
- Add usb_storage to initrd.availableKernelModules so stage-1 binds the
stick and /dev/disk/by-label/* appears.
- Blacklist uas + usbcore.autosuspend=-1: force the slower-but-reliable
Bulk-Only Transport path and stop the boot medium being power-suspended
mid-I/O — both were causing "device offline error" bus drops.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
batm3-installed existed as a nixosConfiguration but had no dd-able disk
image (only the live ISO, which is tmpfs — no persistent state.db/.env).
Mirrors the douro/sintra make-disk-image blocks, with one improvement:
boot.growPartition + fileSystems."/".autoResize so the root partition
and ext4 expand to fill the target drive on first boot. Flashing is
dd-and-done — no manual parted/resize2fs — and the full drive is
available to the nix store from day one (the #55 headroom lesson).
Image-only override via extendModules: the running system's
batm3-installed config (what auto-upgrade rebuilds against) is
unchanged.
Build: nix build .#disk-image-batm3 → result/nixos.img

The bitspire-env activation seeds .env only when ABSENT (never refreshes on
redeploy), and env WINS over the pairing seed — so any value written at first
boot is frozen for the disk's life and silently masks the seed's source. That's
how a dead relay.aiolabs.dev and a provisioned VITE_OPERATOR_PUBKEYS made stale
installs "work" while a fresh machine broke.
Seed ONLY image-baked, non-maskable values (model, fiat, ELECTRON_FORCE_PROD,
DISPLAY, empty VITE_SPIRE_SEED placeholder). Relay + server pubkey come from the
seed; operator pubkey + fee config come from LNbits over the transport — so those
keys are no longer pre-seeded at all. VITE_RELAY_URL / VITE_LNBITS_SERVER_PUBKEY
are emitted only when the operator deliberately pins them via the Nix options (an
explicit override). Also drops the inert RELAY_URL/LNBITS_SERVER_PUBKEY lines from
/etc/bitspire/config.env (never loaded — EnvironmentFile is forced to .env).
Verified: built sintra-installed .env template is 5 lines, 0 maskable vars.

The bitspire-env activation seeded VITE_RELAY_URL from the relayUrl option
(default wss://relay.aiolabs.dev). Because env wins over the pairing seed, every
fresh machine pinned itself to that relay — which is dead — so a scanned seed's
relay was ignored ("No connected relays"; hit live on the aio-demo USB). Default
relayUrl to "" so both relay and server pubkey come from the seed; a non-empty
option now pins a machine (an explicit override) rather than being the default.
Descriptions updated to match.

The USB disk image was systemd-boot (UEFI-only) with make-disk-image's "efi"
table (pure GPT + ESP, protective MBR). The Sintra's Aaeon UP Board firmware
USB-boots in Legacy/BIOS mode — it boots the live ISO via that ISO's isolinux
(BIOS) El Torito image, not the UEFI ESP — so a dd'd systemd-boot image has no
BIOS boot code to execute and the firmware won't list it (a hand-added hybrid
MBR didn't help: nothing to run).
Switch the USB target to GRUB with BIOS + UEFI on make-disk-image's "hybrid"
table: it adds a bios_grub partition, GRUB writes its BIOS stage to the MBR AND
a removable /EFI/BOOT/BOOTX64.EFI — mirroring the live ISO's dual boot. The
Aaeon now lists it (as two "ia android" entries, BIOS + UEFI) and boots it.
Scoped to disk-image-sintra-usb only; the eMMC install keeps systemd-boot.
ESP stays partition 1 so the ESP-USB relabel step is unchanged.
Verified on hardware: booted from USB into the wizard with the full upboard.nix
hardware config.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
A USB-bootable Sintra image variant for booting on a machine whose eMMC
already holds a nixos/ESP-labelled install. make-disk-image hardcodes the
root/ESP labels (nixos/ESP); booting the standard image from USB next to
the eMMC races stage-1's by-label/nixos between the two roots and likely
mounts the eMMC. This variant labels root nixos-usb (via make-disk-image
-L) and relabels the ESP to ESP-USB in a post-step (mtools), with
fileSystems pointed at the new labels. Auto-upgrade is disabled — it's a
portable test / hand-off image, and that also removes scheduled bootloader
writes that could land on the eMMC's ESP.

The dev autoUpgrade flake URL still referenced the pre-migration repo
(aiolabs/lamassu-next), so the Sintra test unit would auto-pull
lamassu-next/dev at 04:00 — which lacks all the bitspire work (the
QR-pairing wizard, etc.) and would revert the box to the old no-seed
build. Repoint it at aiolabs/bitspire?ref=dev, the post-migration home
of this code. lamassu-next still feeds the not-yet-converted production
ATMs (batm3, douro) until they migrate.

provision-atm.sh now writes VITE_SPIRE_SEED (the spire-seed:v1: pairing seed
from spirekeeper) as the production identity, validating the scheme prefix;
the generated nsec path is kept only as a dev fallback when SPIRE_SEED is
unset. Relay default moved to the LNbits bundled nostrrelay
(ws://$HOST_IP:5001/nostrrelay/test). .env templates (live.nix + the flake's
installed-default) swap VITE_ATM_PRIVATE_KEY → VITE_SPIRE_SEED and drop the
dead LP-era vars. README notes state.db now also holds the bunker binding
(keep it or re-pair).
Part of Phase E, aiolabs/bitspire#52. Unblocks the Sintra live-pairing smoke.

The fresh-boot `/var/lib/bitspire/.env` template at flake.nix's
`bitspire-env` activation script seeded `VITE_RELAY_URL=` empty, which
forced every operator to run `provision-atm.sh` (or hand-edit .env)
before the renderer could resolve a relay. Meanwhile the NixOS option
`services.bitspire.relayUrl` was wired only to the dead-code
`/etc/bitspire/config.env` (mkForce-shadowed by `/var/lib/bitspire/.env`).
Thread the NixOS option through: seed `VITE_RELAY_URL=${cfg.relayUrl}`
on first boot. The .env override path remains intact — provision-atm.sh
or a hand edit still take precedence at runtime (the file is the
EnvironmentFile, not the activation-time template). Existing ATMs
already have a populated `.env` and aren't affected (the activation
script's `if [ ! -f ... ]` guard skips the rewrite).
Renderer resolution order:
/var/lib/bitspire/.env → NixOS module default → renderer fallback
(`ws://localhost:7777` in lightning.ts:63 / main.ts:284)
Also expand the `services.bitspire.relayUrl` option description so
future readers see the wire-through + the override path documented
where the option lives.

Closes gap 2 from coord log 2026-06-01T18:30Z. The LNbits withdraw
extension's nostr-transport RPC now populates `link.lnurl` from
`settings.lnbits_baseurl` (aiolabs/withdraw#1 / commit e9d911e), so the
ATM no longer needs a separate HTTP URL on the wire to compose the
LNURL-withdraw callback itself.
What goes:
- `VITE_LNBITS_HTTP_URL` env var (renderer + Electron main)
- `lnbitsHttpUrl` field on `LightningConfig`, `RuntimeConfig`, and the
Window mirror in `src/types/electron.d.ts`
- The manual `${lnbitsHttpUrl}/withdraw/api/v1/lnurl/${unique_hash}`
composition in `generateLnurlWithdraw`
- The `encodeLnurl` bech32 helper in `lightning.ts` (LNbits returns
bech32-encoded; we just `.toUpperCase()` to match BOLT/LNURL convention)
- `@scure/base` dep from `apps/machine/package.json` (only used by the
removed helper; clink still uses it directly)
- The `lnbitsHttpUrl` option + `LNBITS_HTTP_URL=…` env var + boot echo
in `deploy/nixos/bitspire-atm.nix`
- Doc references in CLAUDE.md, README.md, deploy/nixos/README.md,
docs/architecture-comparison.md, and the lightning-check skill
What stays:
- `link.lnurl` consumption, with an explicit error if LNbits returns
null (which signals `LNBITS_BASEURL` is unset on the server side —
better to fail clearly than silently)
- The receiver-side bech32 uppercasing (LNbits returns lowercase per
the standard library)
Why this is a net win:
- Removes a config-drift surface — if LNbits's external URL moved
(DNS, port, reverse-proxy rewrite), every ATM in the field would
stop issuing redeemable LNURL-withdraw QRs until reconfigured.
Now LNbits derives its own URL from `settings.lnbits_baseurl`,
one source of truth.
- Removes an extra provisioning step. No more `LNBITS_HTTP_URL=…`
before running `provision-atm.sh`; the relay + server pubkey suffice.
- Removes the misleading boot echo that triggered the §`18:30Z`
smoke triage confusion ("LNbits HTTP: <url>" read like ATM-→-LNbits
connectivity, when it was only ever a URL embedded in customer QRs).
Also adds a `# pragma: allowlist secret` marker above the
`VITE_ATM_PRIVATE_KEY` doc block in `.env.example` so the global
secret scanner stops false-positiving on the documentation prose.
Workspace typecheck + 24/24 apps/machine tests still green.

Main's commit e5d7a86 ("chore: set ATM_DB_PATH env var for atm-tui")
added two ATM_DB_PATH lines pointing at /var/lib/lamassu-atm/state.db
AFTER dev had forked. Dev's path-rename commit (10d2869) couldn't
touch those lines because they didn't exist on dev's base; the
rebase brought them in unchanged, undoing the lamassu-atm → bitspire
data-dir migration for the ATM_DB_PATH consumers.
Re-point both occurrences at /var/lib/bitspire/state.db so atm-tui
and other ATM_DB_PATH consumers reach the actual on-disk location.
isoImage.isoName was renamed to image.fileName in 25.11 (unified

Three breakages handled:
- hardware.opengl → hardware.graphics (renamed in 24.11). Touches
upboard.nix, douro.nix, batm3.nix, live.nix.
- vaapiIntel dropped — legacy pre-Broadwell driver, removed in
nixpkgs. UP Board (Cherry Trail) and OptiPlex 9030 (Haswell) both
use intel-media-driver, which stays.
- vaapiVdpau renamed → libva-vdpau-driver.
system.stateVersion stays 24.05 — convention is to never bump after
install. Existing Sintra and fresh flashes keep the 24.05 state
semantics; that's correct.

System-level half of the lamassu → bitspire rebrand the rest of dev
already did at the path / service / package layers. Touches user/group
declarations, every systemd `User=` block, the udev rules filename, all
chown calls in flake.nix + live.nix, the displayManager autoLogin user,
the trusted-users nix entry, provision-atm.sh's ATM_USER, plus README +
CLAUDE.md doc references.
In-place migration for the Sintra dev unit (which auto-pulls dev at
04:00) lives in `system.activationScripts.bitspire-user-migration` and:
- copies `/home/lamassu/.ssh/authorized_keys` → `/home/bitspire/` once,
so SSH access survives the rename
- recursively chowns `/var/lib/bitspire` to the new bitspire UID on
every boot — cheap no-op once done, but covers the case where the
data dir was written by the now-removed lamassu UID
- leaves `/home/lamassu/` in place as evidence; operator can `rm -rf`
after confirming bitspire login works
Recovery path if the migration breaks SSH access: root key is still in
configuration.nix:142-144 (padreug@gizmo), so ssh root@<host> works.

- nixosConfigurations.sintra-installed reuses the existing UP Board
hardware module (deploy/nixos/hardware/upboard.nix). Sintra has
identical peripheral layout to tejo — Aaeon UP Board with iVIZION
validator on ttyJ5 and Fujitsu F56 dispenser on ttyJ7 — so no new
hardware nix module is needed.
- packages.x86_64-linux.disk-image-sintra is a raw GPT disk image
consumable via \`dd if=result/*.img of=/dev/<eMMC>\`. Mirrors the
existing disk-image-douro shape.
- bitspire-env activation script (the template that lands at
/var/lib/bitspire/.env on first boot) now emits LNbits fields
(VITE_LNBITS_SERVER_PUBKEY, VITE_LNBITS_HTTP_URL) instead of the
retired LP fields. Empty values mean the ATM boots into a
"needs provisioning" state, ready for provision-atm.sh to fill in.
Evaluations confirmed: nix eval .#nixosConfigurations.sintra-installed
and .#packages.x86_64-linux.disk-image-sintra both resolve.

Five-file coordinated rename to give the dev-branch deploy a clean
`bitspire` namespace at the NixOS level:
deploy/nixos/lamassu-atm.nix → deploy/nixos/bitspire-atm.nix
- `services.lamassu-atm` → `services.bitspire`
- `systemd.services.lamassu-atm` → `systemd.services.bitspire`
- `/var/lib/lamassu-atm` → `/var/lib/bitspire`
- `/opt/lamassu-atm` → `/opt/bitspire`
- `/etc/lamassu-atm/config.env` → `/etc/bitspire/config.env`
flake.nix
- module import path updated
- `nixosModules.lamassu-atm` → `nixosModules.bitspire`
- `system.activationScripts.lamassu-env` → `bitspire-env`
- all activation-script paths point at /var/lib/bitspire
deploy/nixos/configuration.nix
- `networking.hostName = "lamassu-atm"` → `"bitspire"`
deploy/nixos/live.nix
- module import path updated
- ISO name template: `lamassu-atm-<model>-live.iso` → `bitspire-<model>-live.iso`
- activation-script name updated
deploy/nixos/provision-atm.sh
- data-dir paths: /var/lib/lamassu-atm → /var/lib/bitspire
- systemctl + journalctl unit names updated
DELIBERATELY kept as `lamassu` (for now):
- The `lamassu` UNIX user and group account. Renaming would
require file-ownership migration scripts; the Sintra is a
fresh flash so no existing data, but the internal user
namespace inconsistency is acceptable.
- LP-specific bits in provision-atm.sh (admin token, the
`docker logs lamassu-lightning-pub` extractor) — those
get ripped out in 3c when the script switches to LNbits.
NO migration activation script added — the Sintra flash is fresh,
production batm3/douro stay on `main` and never see this branch.
A future dev→main cutover will need a separate migration story
(rename UNIX user, move /var/lib/lamassu-atm → /var/lib/bitspire,
SSH key relocation, etc.).

nix eval .#nixosConfigurations.batm3-installed.config.systemd.services.bitspire.enable

Three root-level identifier renames:
- Root package.json `name`: lamassu-next → bitSpire
- flake.nix nixosConfigurations.lamassu-live-*: kept (legacy
aliases) and ADDED bitSpire-live-* alongside. Both work.
Drop the lamassu-* aliases at the final cutover once nothing
references them.
- nix/mkAtmApp.nix `pname`: lamassu-atm-app → bitspire-atm-app
(lowercase to match nix package naming conventions; the
Electron app's externally-facing names get their own commit).
What's NOT renamed here (per the plan):
- Hardware-named outputs (douro, tejo, sintra, batm3) — those
are physical product names.
- nixosConfigurations.{douro,tejo,sintra,batm3} ergonomic
aliases — same reason.
- nixosModules.lamassu-atm + its imported file — that's the
systemd service, deferred to 2d.
- apps/machine/package.json appId/productName — Electron
identity, deferred to 2c.

The system.autoUpgrade flake URL had no explicit ref, so the auto-pull
at 04:00 resolves to the repo's default branch (main). That's correct
for production ATMs flashed from main, but it would silently regress
a Sintra flashed from dev back to main code overnight.
Pin to ?ref=dev on the dev branch so any ATM deployed from dev stays
on dev. The main branch's flake.nix stays unchanged — production ATMs
keep pulling main HEAD as before.
First commit on the new dev branch. Tagged pre-bitspire-cutover on
main beforehand as a rollback target.

Follow-up to 9430c9b. `max-jobs = 1` reopened the door for ANY uncached
derivation to build locally, including derivations whose outputs SHOULD
be substituted but happen to miss the cache (network blip, hash drift,
operator forgot to push). On ATM hardware a kernel/electron/rustc build
would take literal hours and silently wedge the kiosk while it churns.
`timeout = 60` caps every local build's wall-clock at 60s. Activation-
time stitches (boot.json, system-units, X-Restart-Triggers, etc.) finish
in well under a second; anything that doesn't return by 60s is by
definition a heavy compile that has no business running on an ATM.
Killing it fast makes the upgrade fail loudly so the operator can fix
the cache miss, rather than the box silently chewing CPU all night.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
NixOS generates several trivial activation-time derivations that are
hardcoded with `allowSubstitutes = false` + `preferLocalBuild = true`
— most visibly `boot.json` (the bootspec) and `nixos-rebuild`. These
will NEVER appear in any binary cache (cachix follows the
non-substitutable flag) and they CAN'T be substituted (allowSubstitutes
= false). They're only realized via local build.
With `max-jobs = 0`, that's structurally impossible, so every nightly
`nixos-upgrade` across the fleet has been failing for at least a week:
May 19 04:00:36 lamassu-atm: Cannot build '/nix/store/...-boot.json.drv'
May 20-24 04:00:xx: Cannot build '/nix/store/...-nixos-rebuild.drv'
May 25 04:11:17 lamassu-atm: Cannot build '/nix/store/...-atm-transactions.drv'
The kiosk kept running so nobody noticed — the systemd unit fails but
the old generation continues. Caught when re-provisioning the Sintra
dev unit to the demo LNbits today and the migration commits wouldn't
land.
`max-jobs = 1` allows one concurrent local build slot. Heavy compiles
(kernel, rustc, electron) DON'T have `preferLocalBuild`, so they still
go through normal substitution and effectively never build locally
because they're cached upstream. The slot exists strictly to unblock
the trivially-cheap activation-time stitch derivations.

(local-overlay-store / stale-file-handle FAILs at exit 1) that triggers
when the determinate-nix-3.16.3 derivation has to be built from source
locally — no aiolabs.cachix nor cache.flakehub.com substituter has the
output cached for our exact nixos-24.05 / x86_64-linux combo, so the
build evaluates the test phase and fails.
Bumping the semver pin from `?3` (≥3.0.0 → resolves to 3.16.3) to
`?3.15` (≥3.15.0 → resolves to 3.20.0) skips past the regression.
3.20.0 builds cleanly; nix bumps from 2.33 → 2.34.6 across the BATM3
fleet once it auto-pulls.
Mirrors the same fix already applied on dev in 6d8c217.

Without --refresh, nix caches the flake evaluation and
nixos-upgrade may not pull the latest commits. The --refresh
flag forces re-fetching the git repo on every upgrade.
Only affects flake evaluation cache — /var/lib data is untouched.

Standalone Node.js script that generates a Lightning invoice for
the ATM's Lightning.Pub account. Reads config from .env, connects
to the relay, creates an invoice via Nostr RPC, displays a QR code
in the terminal, and prints the BOLT11.
Bundled as self-contained CJS with esbuild (all dependencies inlined)
so it works from the nix store without separate node_modules.
Usage: fund-atm <amount_sats>
e.g. fund-atm 100000
fund-atm 100000 sats
Added to NixOS systemPackages for both live and installed configs.

HP ProDesk 600 G3 DM hardware module (temporary board replacement for
BATM3). Includes batm3-installed nixosConfiguration with auto-upgrade,
cachix, and systemd-boot.

Add batm3 to flake.nix NixOS configs, live.nix (CDC ACM kernel modules,
MEI udev rules), and build-iso.sh. Default fiat: USD.

Add atm-tui as a flake input and include it in environment.systemPackages
for both live and installed NixOS configs. The TUI will be available as
'atm-tui' on PATH after deployment — no more manual SCP.
The binary is pushed to cachix alongside the ATM app, so douro pulls
it from the binary cache on upgrade (no local compilation needed).

- Add tejo-specific udev rules for both UP Board and UP4000 variants
(serial symlinks ttyJ4/J5/J7, camera, LED SPI, I2C, USB autosuspend)
- Add USB serial kernel modules (usbserial, ftdi_sio, cp210x) for tejo
- Add tejo serial console kernel params (ttyS4 debug UART)
- Fix upboard.nix: hardware.graphics → hardware.opengl (NixOS 24.05)
- Add tejo-installed nixosConfiguration with model-specific auto-upgrade
- Parameterize auto-upgrade flake URL per machine model

The ATM should never compile from source — only download pre-built
binaries from cachix/cache.nixos.org. If a derivation isn't cached,
the upgrade fails cleanly instead of trying to build on the mSATA.

Without this, freshly flashed ATMs have mismatched nix store hashes and
fall back to building from source instead of pulling cachix binaries.
Matches the installed config which already had this.

Same fixes as live.nix: disable SwiftShader, enforce MemoryMax=1G,
add 1GB swap file, and clean /tmp on boot. Applies to douro-installed
and tejo-installed configs used by nixos-rebuild on disk-installed ATMs.

Resolves the cachix binary cache hash mismatch between local dev machines
(Determinate Nix 2.33) and douro (stock Nix 2.18). With both sides using
Determinate Nix, `cachix push` from local builds produces store paths that
douro's 4am auto-upgrade can download directly instead of building from source.

- Passwordless sudo for lamassu user (nixos-rebuild without TTY)
- Cachix binary cache (aiolabs) as substituter
- Daily auto-upgrade timer pulling latest flake from Forgejo
- trusted-users includes lamassu for nix commands

Move deploy/nixos/flake.nix into the root flake.nix, adding mkAtmApp
for pure Nix builds of the Electron app (no local pnpm needed). Simplify
build-iso.sh to a thin wrapper around `nix build .#iso-<model>`. Add
douro hardware configuration. Streamline live.nix to consume the
Nix-built app package.

- Add dev.sh script for managing regtest development environment
- Implement cmd_fund to fund ATM app owner via Lightning.Pub API
- Add --fund flag to cmd_up for automatic funding on startup
- Update setup_atm_app to write VITE_APP_ID to machine .env
- Fix Electron IPC to pass appId and extensionApiUrl to renderer
- Restructure repo from nested lamassu-next/ to root
The dev.sh script now supports:
- ./dev.sh up --fund # Start regtest and auto-fund ATM
- ./dev.sh fund # Fund existing ATM app
- ./dev.sh status # Show environment status
- ./dev.sh reset # Clean restart
