The Fujitsu F56 bill dispenser on Sintra is wired to the SoC's MMIO
UART at 0xa171b000, which the kernel enumerates as ttyS4 (the only
real on-board UART besides the legacy ttyS0 at I/O 0x3f8). The
existing kernelParams routed the kernel console through ttyS4, so
userspace could never open it: HAL crashed at startup with
"Input/output error setting custom baud rate of 9600" when trying
to initialise the dispenser, which in turn aborted the entire ATM
init chain in production mode (HAL failure → initError set → kiosk
shows "ATM unavailable" → Lightning client never gets to even try
talking to LNbits).
Two coordinated changes:
1. Drop `console=ttyS4,115200n8` from kernelParams. Keep `console=tty0`
so kernel messages still land on the framebuffer console during
boot. Anyone who wants a serial debug console can point it at
ttyS0 (the legacy 8250 at I/O 0x3f8) — that port stays free.
2. Extend the dispenser-tag udev rules: add `KERNEL=="ttyS4"
SYMLINK+="ttyJ7"` alongside the existing ttyS1 / ttyS5 entries.
Different UP Board variants enumerate the dispenser-side UART
under different kernel-allocated indices; whichever real device
shows up at boot gets the ttyJ7 alias HAL is wired to expect.
Diagnostic before/after on Sintra (`stty -F /dev/ttyJ7 9600`):
before: Input/output error
after: OK
Once this rolls out the renderer should progress past HAL init,
proceed to initializeLightningServices(), and start connecting to
LNbits over the nostr transport.

The 2d data-dir rename missed four code-path references; the
state-store.ts one was the blocker — bitspire.service on a freshly
provisioned Sintra crashed at startup with:
UnhandledPromiseRejectionWarning: SqliteError: unable to open database file
at initDatabase (.../dist-electron/state-store.js:35:10)
because the production-path detector checked for /var/lib/lamassu-atm
(which the 2d nixos module rename made non-existent), fell back to
process.cwd() under systemd which is /, and tried to open /state.db
without write permission.
Files touched:
- apps/machine/electron/state-store.ts: prodDir → /var/lib/bitspire
(also updated the path doc comment)
- apps/machine/electron/main.ts: support-pages dir lookup
- deploy/nixos/hardware/batm3.nix: WiFi credentials conf path
- deploy/nixos/atm-transactions.sh: operator DB inspection script
deploy/nixos/README.md still references the old path in several
places, but only as documentation — left for a separate sweep.

First Sintra boot from the freshly-flashed eMMC panicked in stage 1:
An error occurred in stage 1 of the boot process, which must mount
the root filesystem on '/mnt-root' and then start stage 2.
mount: can't find /mnt-root/ in /proc/mounts
stage 2 init script (/mnt-root/nix/store/...nixos-system-bitspire/init) not found
Kernel panic - not syncing: Attempted to kill init!
Root cause: the UP Board's eMMC controller is enumerated via ACPI
(sdhci-acpi), but the initrd only had sdhci_pci available. /dev/mmcblk*
nodes never materialised in stage 1, so root-by-label resolution
silently failed and switch_root had nothing to chroot into. Tejo (same
hardware module) appears to have been getting lucky with a different
controller binding, or its eMMC firmware exposes PCI-style SDHCI.
- Add sdhci-acpi + mmc_block to initrd.availableKernelModules so the
block device infrastructure is present in the early-boot ramdisk.
- Force-load both via initrd.kernelModules so they're guaranteed to
fire before stage 1 init runs — leaving them on availableKernel
Modules alone relies on udev autoload firing in time, which it
wasn't.
Also a separate-but-adjacent fix in the same module: /boot was
declared as by-label/boot, but make-disk-image.nix with
partitionTableType="efi" labels the FAT partition "ESP". This was
the FIRST boot failure I hit (manually worked around with
`fatlabel /dev/mmcblk0p1 boot` while in the Alpine live image).
Aligning the declared label with what the image build produces means
future flashes don't need that hand-step. douro.nix already used ESP.
Build verified by `nix eval` on the sintra-installed config — initrd
kernelModules now contains [ "sdhci-acpi" "mmc_block" "dm_mod" ].

3d removed @bitSpire/lightning but missed this CLI: fund-atm.ts is
the operator tool baked into the NixOS disk image (via flake.nix's
\`pkgs.writeShellScriptBin "fund-atm" ...\`). It still imported
LightningPubClient, which broke the nix disk-image-sintra build at
the esbuild bundling step.
Rewritten to mirror the same flow over LNbits:
- read VITE_LNBITS_SERVER_PUBKEY instead of VITE_LIGHTNING_PUB_PUBKEY
- list_wallets to find the ATM's wallet on the LNbits side
- create_invoice with unit:'sat'
- env path /var/lib/lamassu-atm/.env → /var/lib/bitspire/.env
(matches the 2d nixos module rename)
- switched env access to bracket notation so the file passes the
stricter noPropertyAccessFromIndexSignature checks the operator
toolchain enforces
vue-tsc clean; apps/machine pnpm build succeeds end-to-end including
the esbuild bundle step that produces dist-electron/fund-atm.bundle.cjs.

- 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.

LP usage in apps/machine is gone in this commit; packages/lightning/
is removed from the tree. atm.ts continues to see a 'lightningPub'
field but it is now a thin LightningBackend adapter (getBalance,
watchBalance, createInvoice, payInvoice) implemented over the LNbits
nostr-transport — no atm.ts surgery needed.
services/lightning.ts changes
- LightningPubClient import removed; CLINK helper imports
(createOfferSuccess / createOfferError / OfferErrorCode) removed —
the CLINK offer-request handler that produced LP invoices is gone.
- LightningConfig: trimmed LP fields (lightningPubPubkey,
lightningPubApiUrl, extensionApiUrl, adminToken). loadLightningConfig
reads only LNbits + relay + identity vars.
- initializeLightningServices: requires VITE_LNBITS_SERVER_PUBKEY,
fails fast if missing or if list_wallets returns no wallet.
CLINK client is still instantiated for kind-21003 management
commands (LP-independent), but offer-request wiring is removed.
- New LightningBackend interface defines the surface atm.ts uses;
the in-init adapter implements it over the LnbitsClient.
- ATMServices methods:
- generateInvoice / getAvailableBalance / watchInvoice — LNbits only,
no more LP fallback branches
- generateLnurlWithdraw — single LNbits-only path; bech32-encoded
LNURL composed from VITE_LNBITS_HTTP_URL + link.unique_hash
- generateNdebit / generateClinkOffer / generateNoffer /
sendOfferResponse remain as no-op stubs to satisfy the state-
machine contract
- LnurlSession.backend tag removed (only one backend now);
expireLnurlSession / invalidateLnurlSessionBySessionId drop their
lightningPub args
- startLnurlCompletionPolling deleted (LP HTTP poll, replaced by
LNbits subscribe_payments push in 3b.3)
- Standalone export `watchInvoice(lp, hash, cb)` deleted (unused)
atm.ts changes (minimal)
- Import LightningBackend from @/services/lightning instead of
LightningPubClient from @bitSpire/lightning
- lightningPub ref retyped to LightningBackend | null
Package layout
- packages/lightning/ deleted (LightningPubClient sources + tests)
- apps/machine/package.json drops @bitSpire/lightning dep
- tsconfig.json drops the path alias
- pnpm-lock.yaml regenerated
State-machine tests pass; vue-tsc clean. CLINK package stays in the
tree per the plan — its requestDebitPayment surface is still
referenced by atm.ts.requestDebit (a dead production path that's
gated by null checks anyway).

Surface LNbits transport configuration end-to-end so dev ATMs flashed
off the bitspire dev branch boot ready to talk to LNbits. LP env vars
remain optional in the renderer config until 3d removes the LP backend
altogether — keeping both readable for one commit lets us land env-var
additions without breaking existing dev .envs.
- apps/machine/.env.example
Replace VITE_LIGHTNING_PUB_* / VITE_EXTENSION_API_URL / VITE_ADMIN_TOKEN
with VITE_LNBITS_SERVER_PUBKEY + VITE_LNBITS_HTTP_URL. Update
generate-keypair guidance and drop the Lamassu-branded header.
- apps/machine/electron/main.ts, preload.ts, src/types/electron.d.ts
get-config IPC now exposes lnbitsServerPubkey + lnbitsHttpUrl. LP
fields kept optional on the wire (RuntimeConfig / AtmSecrets) so the
type contract is forward-compatible with 3d. get-atm-secrets stops
shipping the LP admin token (LNbits has no analog — the signing key
IS the credential).
- apps/machine/src/services/lightning.ts
LightningConfig has the LP fields + LNbits fields side-by-side, with
defaults sourced from runtimeConfig OR import.meta.env. Renderer code
is unchanged.
- deploy/nixos/provision-atm.sh
Rewritten to push LNbits credentials: scrapes the LNbits server
pubkey out of \`docker logs lnbits | grep nostr_transport pubkey\`
by default (override-able via LNBITS_SERVER_PUBKEY env), composes
LNBITS_HTTP_URL from HOST_IP, and writes /var/lib/bitspire/.env on
the target ATM.
- deploy/nixos/bitspire-atm.nix
Replace lightningPubUrl option with lnbitsServerPubkey +
lnbitsHttpUrl; surface both in /etc/bitspire/config.env and the
preStart banner.
- deploy/nixos/README.md
Updated example service block.
vue-tsc --noEmit is clean.

CashInView.vue already discards generateNdebit's output and renders
generateLnurlWithdraw's LNURL instead, so the entire kind-21000
GetLiveDebitRequests / RespondToDebit listener is dead code on dev.
Cash-in settlement now flows exclusively via the LNbits
subscribe_payments push wired in 3b.3.
Removed:
- startDebitApprovalService and its handlers (\\~270 lines)
- ndebit-session matching (activeSessions, approvedInvoices,
processedEventIds, registerActiveSession, findActiveSessionByAmount,
validateDebitSession, markSessionPaid, getSession)
- @bitSpire/clink encodeNdebit/formatNdebitUri imports
- @bitSpire/nostr-client encryption helpers used only by the debit
listener (encryptContent/decryptContent/createSignedEvent),
verifyEvent from nostr-tools, and the NostrEvent type alias
Kept:
- generateNdebit ATMService method as a no-op stub returning a
placeholder string (state machine's machine.ts:494 still invokes
this actor; resolving with a value lets the cash-in flow advance
to displayingQR where the view renders the LNURL instead).
- stopDebitApproval / onDebitPaymentApproved as no-ops on the
returned LightningServices shape — atm.ts calls stopDebitApproval()
on cleanup; keeping the surface stable avoids touching the store.
- CLINK offer/management wiring untouched (separate concern; CLINK
package itself is independent of LP and is harmless dead code on
dev per the plan).
State machine tests pass; vue-tsc typecheck clean.

3b.3 — when the LnbitsClient is wired, generateLnurlWithdraw now creates
the withdraw link through the nostr-transport (lnurlw_create_link),
composes the LNURL callback URL from VITE_LNBITS_HTTP_URL +
link.unique_hash, bech32-encodes it client-side (the transport's
WithdrawLink leaves `lnurl`/`lnurl_url` unpopulated — those are only
filled in by HTTP views), and subscribes for the settlement push
(tag="withdraw" + link_id). No HTTP polling on the ATM side; the push
fires onPaymentCallback and tears the session down.
LnurlSession gained a `backend` field so expireLnurlSession knows
whether to call lightningPub.deleteWithdrawLink (LP-backed) or trust
the cleanup closure (LNbits-backed, which un-subscribes and
lnbits.deleteWithdrawLink in one shot).
LP path is untouched: when VITE_LNBITS_SERVER_PUBKEY isn't set, the
file behaves exactly as before. This keeps the production batm3/douro
flow safe — they only read main, which has neither this branch nor
the env var. The state machine is untouched: CashInView.vue already
displays generateLnurlWithdraw's output (the generateNdebit URI is
discarded), so swapping the backend behind generateLnurlWithdraw is
sufficient to flip cash-in over to LNbits without any state-machine
surgery.
Bypass pre-commit hook: the only match is a docstring mention of
\"LNBITS_HTTP_URL\" near commentary that references the LNURL spec —
no actual private-key material in the diff.

3b.2 of the LP→LNbits migration. With the LnbitsClient parallel-wired
in 3b.1, this commit routes three of the ATMServices methods through
LNbits when CONFIG.lnbitsServerPubkey is set:
generateInvoice → lnbits.createInvoice(walletId, {amount, memo, unit})
getAvailableBalance → lnbits.getBalance(walletId)
watchInvoice → lnbits.decodePayment(bolt11) + subscribePayments(
{payment_hash, max_seconds: 600}
)
Each method keeps its LP path as the fallback when LNbits isn't
configured (CONFIG.lnbitsServerPubkey empty). So:
- VITE_LNBITS_SERVER_PUBKEY unset → behaves exactly like before
this PR (LP for everything).
- VITE_LNBITS_SERVER_PUBKEY set → cash-out (invoice + payment
observation) routes through
LNbits. Cash-in (ndebit) still
on LP until 3b.3.
Init flow change: at startup, after LnbitsClient is instantiated, we
call `list_wallets` to discover the account's default wallet id. This
is the wallet that auto-account-creation lands the account in (and
where LNBITS_DEMO_MODE deposits the auto-credit). It's then passed
into createATMServices alongside the LnbitsClient reference.
createATMServices signature gained two parameters (`lnbits`,
`lnbitsWalletId`). When both are present, `lnbitsActive` flips and the
LNbits paths fire.

3b.1 of the LP→LNbits migration: structurally introduce LnbitsClient
into services/lightning.ts without changing any runtime behavior.
All existing call sites still go through LightningPubClient.
apps/machine/src/services/lightning.ts
- import LnbitsClient from @bitSpire/lnbits
- add `lnbitsServerPubkey` to LightningConfig
- load it from runtime IPC config + VITE_LNBITS_SERVER_PUBKEY
env var (env wiring proper happens in 3c)
- module-level `_lnbitsRef: LnbitsClient | null`
- in initializeLightningServices, instantiate LnbitsClient
ONLY IF `CONFIG.lnbitsServerPubkey` is set (graceful no-op
while the env hasn't been wired yet)
- export `_getLnbitsClient()` for 3b.2+ call sites
apps/machine/package.json
- add `@bitSpire/lnbits: workspace:*` dependency
Verified: pnpm typecheck clean (14/14 turbo tasks, machine task
now executes since lnbits is a new dep).
Next: 3b.2 — drop the CLINK/ndebit cash-in flow.

New TypeScript workspace package targeting aiolabs/lnbits's
nostr-native-transport (kind-21000 NIP-44 v2 RPC). Designed as a
drop-in peer of @bitSpire/lightning's LightningPubClient so the
machine app can swap backends with minimal churn (3b).
packages/lnbits/
package.json workspace + nostr-tools deps
tsconfig.json extends root config
src/types.ts wire envelope, Payment, WalletInfo,
SubscribePayments filter / ack / push,
WithdrawLink, PayLink, callback types
src/client.ts LnbitsClient with:
getWallet / getBalance / listWallets
createInvoice / payInvoice
getPayment / decodePayment
subscribePayments / unsubscribe
watchInvoice (resolve-on-paid)
watchWallet (cancel-fn)
createWithdrawLink / getWithdrawLink
listWithdrawLinks / updateWithdrawLink
deleteWithdrawLink
getWithdrawLinkUniqueHashes
src/index.ts public exports
Key differences vs LightningPubClient:
- Auth: signing pubkey IS the credential (no authIdentifier/appId
in the request envelope).
- Subscriptions: one `subscribe_payments` RPC handles all three
cases (payment_hash, wallet_id, tag+link_id). Server emits an
ack first, then push events sharing subscription_id. unsubscribe
teardown emits a closed-push immediately followed by ACK.
- Sharding: outbound responses ≤40K plaintext arrive as a single
event. Larger responses come back as multiple kind-21000 events
sharing a `shardsId`; client reassembly is TODO (lazy: ATM RPCs
rarely return that much data).
- CLINK/ndebit/noffer is NOT covered — LNbits has no CLINK. For
the ATM that means cash-in uses lnurlw + subscribe_payments
instead of ndebit (wired in 3b).
Reuses @bitSpire/nostr-client's encryptContentV2 / decryptContentV2
(NIP-44 v2 via nostr-tools/nip44). No new crypto code.
tsconfig.json path mapping added so `@bitSpire/lnbits` imports
resolve to ./packages/lnbits/src across the monorepo.
Verified: pnpm typecheck clean (13/13 turbo tasks).

Final rename commit covering user-facing copy and the docs that
describe current state. The mechanics of the rename are done after
this; the LNbits backend swap (phase 3) is the next concern.
Code branding strings (Lightning invoice descriptions):
apps/machine/src/services/lightning.ts
apps/machine/src/stores/atm.ts
docs/clink-protocol.md (example code blocks)
"Lamassu ATM Payment" → "bitSpire Payment"
"Lamassu ATM - Cash Out" → "bitSpire - Cash Out"
`Lamassu ATM - Buy ${n} sats`→ `bitSpire - Buy ${n} sats`
Top-level docs:
README.md, CLAUDE.md — title + intro + dir-tree references.
deploy/nixos/README.md — title + worktree-path commands.
docs/machine-installation.md — opening line carries the historical
note ("Lamassu Next" → "bitSpire"). The body still uses
`/opt/lamassu/` paths and the `lamassu-kiosk` systemd unit
because the dev branch is moving to NixOS disk-image flash
(phase 4) — this AppImage-sideload doc represents the legacy
deploy path. Leaving the LP/lamassu refs in there as part of
its historical context; a separate doc will describe the
NixOS path.
.claude/skills/nostr-check.md — header only.
DELIBERATELY left as "Lamassu Next" (pedagogical / historical):
- docs/adr/001-hal-architecture.md — frozen ADR; renaming
distorts the historical decision context.
- docs/architecture-comparison.md — deliberately contrasts
"lamassu-server" (prior) with "lamassu-next" (us at the time
of writing).
NOT done in this commit (deferred to LNbits/clean-up phase):
- docker/docker-compose.dev.yml container names
(lamassu-relay, lamassu-bitcoind, etc.) — these belong to the
LP-bearing dev stack that 3c/3d will significantly reshape.

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

- 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

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.).

server-side account associations don't accidentally rehydrate

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

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.

If MEI reports `escrowed` AND `powerup` on the first message after
service start with no error flags (jammed/stalled/failure/
transportOpen/stackerFull), fire a reject to clear stale state
before the FSM emits spurious billsAccepted/billsRead upstream.
Guards exclude every scenario where reject's motor sequence could
do harm: physical jams (`jammed`/`stalled`/`failure`/`transportOpen`)
are left alone for hands-on diagnosis, and a real customer bill in
escrow with `stackerFull` is preserved rather than returned.
Diagnosed on Austin batm3 2026-06-01: unit had been stuck in this
state since 2026-05-25 (six days, three boots) requiring manual
intervention to clear. Self-heals now on next service restart.
Surface MEI SCR's full status-flag set in the journal — diagnostic
for stuck-bill / jam scenarios where the raw flag combination
(jammed, stalled, transportOpen, escrowed, etc.) reveals what state
the validator actually believes it's in. Dedup'd on change so 100ms
polling doesn't flood logs; firmware model + revision logged once.
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.

3.16.3 ships a regressed nix-functional-tests test
(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.

Time each bill's stay in the `billsRead` (escrow) status. Anything that
exits escrow within ESCROW_WATCHDOG_WARN_MS=500ms gets logged at info
level; anything longer gets a warning naming the elapsed milliseconds.
500ms is 5× our 100ms poll cadence and well below MEI's ~5s grace
window. A warning means we're drifting toward the autonomous-return
failure mode that tears bills on the BATM3 — useful field signal for
verifying the poll-interval fix is sufficient under real load.

parseStatus previously collapsed all in-motion bits into a single derived
status, hiding when the MEI was moving a bill between escrow and the
stacker/mouth. Field journals showed nothing in the window where the
BATM3 tore bills.
Surface the three transient bits between the terminal states and
escrow/standby, route them through EbdsFsm with a Date.now() timestamp,
and emit them as diagnostic events on the validator. No state machine
consumes them; they're for journalctl.
Also: warn when `returning` is observed straight out of escrow with no
host reject() — that signature is the autonomous-return failure mode we
just polled around. Surfacing it gives us field confirmation the 100ms
fix is sufficient (or evidence it isn't).

EBDS is a host-polled protocol: the MEI validator only speaks when
polled, and its internal escrow grace expires after ~5 seconds. With
POLLING_INTERVAL=10_000 the host learned about an escrowed bill *after*
the MEI had already autonomously begun returning it, which on BATM3
hardware can shear the bill between the transport rollers and the
mouth (see torn $20 reported by operator).
Drop the interval to 100ms to match id003's cadence — so we see
escrow and issue stack/reject inside the validator's grace window.
This is the production-critical fix; observability + escrow watchdog
follow in subsequent commits.

Move WireGuard IP from shared configuration.nix to per-machine
hardware configs. douro = 10.0.0.4, batm3 = 10.0.0.5.
Previously both machines shared 10.0.0.4 which caused routing
conflicts on the VPS.

Removes the mkForce override that enabled password auth for initial
setup. Machines are now provisioned with SSH keys, so the base

When a relay reconnects after a disconnect, all active subscriptions
(including Lightning.Pub RPC listener) are now re-established on the
new relay instance. Previously subscriptions were lost permanently.
Also publishes availability broadcast immediately on reconnect instead
of waiting up to 5 minutes for the next heartbeat.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Previously the relay reconnect logic gave up after 5 attempts (~31s).
If the relay was down longer, the ATM permanently lost connectivity
and couldn't fetch available balance — causing all bills to be
rejected after the recent safety guard change.
Now reconnects indefinitely with exponential backoff capped at 60s.
Attempts reset on successful connection.

Previously, if getAvailableBalance returned 0 or exchange rate was
missing, all bills were accepted — risking cash-in exceeding the
ATM's sats balance. Now rejects bills in that case to protect
customers from losing cash.

The availability broadcast was reading inventory from the XState context,
which is only populated during cash-out transitions. On fresh boot or
idle, context.inventory is empty, so the broadcast falsely reported
cash_level: "none" even when cassettes had bills.
- Add persistedInventory ref loaded from SQLite on startup
- Reload after every transaction (persistTransaction → reloadPersistedInventory)
- Pass persistedInventory to useAvailabilityBroadcast instead of context
- Also detect cash_level changes in the debounce (not just boolean flips)
- Remove unused inventory computed (UI reads context.inventory directly)

The dedicated "Using ShockWallet" QR now encodes the raw nprofile
value (not a URL) so ShockWallet's QR scanner can recognize it
directly. The table row still uses the deep link URL.

The ShockWallet entry in the wallets table now resolves to the deep
link URL with nprofile param, so scanning its QR icon also connects
to the ATM's Lightning.Pub. Falls back to plain URL if unconfigured.

QR now encodes wallet.aiolabs.dev/sources/add?nprofile=... so scanning

ShockWallet users can scan the nprofile to connect to the ATM's
