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.

Fixes gap-3 from coord log 2026-06-01T18:30Z: the operator-fees
subscriber wasn't running during the 'awaiting-fees' maintenance state,
so the maintenance state had no path to clear. Every restart found
empty state.db, entered maintenance, never subscribed, never wrote.
Forever stuck.
Root cause: `initializeForProduction` bailed via early `return` when
the persisted fee config was null. The subscriber starts inside
`initializeWithHalIpc`, which was never reached.
Fix has three pieces:
1. Remove the early return. HAL + Lightning + operator-fees subscriber
all init even when `initError = 'awaiting-fees'` is set. The
maintenance card UI still blocks user interaction (no router-view
renders), and the state machine starts with zero fractions until
the first event lands.
2. New `UPDATE_FEE_CONFIG` event on the state machine, handled at the
root level — assigns `cashInFeeFraction` / `cashOutFeeFraction` onto
context so subsequent cashIn/cashOut entries pick them up via
setCashInFee / setCashOutFee actions. No actor restart needed.
3. `applyFeeConfig` (the operator-fees subscriber's onApply callback)
now dispatches UPDATE_FEE_CONFIG into the running actor AND clears
`initError` when it was 'awaiting-fees'. Operator publishes the
first event → ATM auto-unblocks → UI flips from maintenance card
to IdleView showing the new fee%. No `systemctl restart bitspire`
needed.
Adds three tests covering the new UPDATE_FEE_CONFIG handler:
- updates context fractions
- does not leave idle state
- propagates to context.feeFraction on next cashIn entry
(the load-bearing chain: subscriber → context → setCashInFee → fee
math is correct for the next transaction)
Total state-machine tests: 21 (was 18); apps/machine tests unchanged
at 24. All 12 workspace packages typecheck.

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.
24 tests for the load-bearing logic introduced by the previous commit:
`src/services/__tests__/operator-fees.test.ts` (10):
- canonical v1 payload with components parses cleanly
- absent schema_version treated as v1 (back-compat with cassette config
doc that shipped without one)
- unknown top-level keys silently ignored (v2 forward-compat)
- absent `components` → WARN + zero breakdown (graceful degrade,
producer-mandatory at v1 but consumer-safe)
- components present but sums disagree with totals → WARN + still
parses (totals authoritative per coord log §`14:25Z`)
- tiny float drift (well under 1e-6) does NOT trip the consistency
assert
- required fields missing → throws
- non-numeric component → throws with the offending key in the message
- FEE_CAP_PER_DIRECTION exposed at 0.15
`electron/__tests__/state-store-fees.test.ts` (14):
- null pre-apply (`getFeeConfig` + watermark)
- round-trip via getFeeConfig after applyFeeConfig
- upsert on subsequent newer event (singleton id=1)
- watermark dedup: rejects equal AND older event.created_at
- persisted row unchanged when stale event is rejected
- 15% per-direction cap: rejects above-cap on either direction
- accepts at the cap boundary exactly
- rejects negative + non-finite fractions
- schema_version < 1 rejected
- non-integer event_created_at rejected
- watermark does NOT advance when payload validation fails (atomicity)
Uses in-memory SQLite (`:memory:`) — fresh DB per test, no on-disk
artifacts, no parallel-test interference.

Layer 3 of the operator-configurable fee architecture (parent
aiolabs/satmachineadmin#37). Replaces the hardcoded
`ref(0.0333)` / `ref(0.0777)` constants in `atm.ts` with a Nostr-
delivered, operator-pushed fee config sourced from satmachineadmin.
Wire envelope (locked with sat-side at #39 + coord log 2026-06-01):
kind=30078 (NIP-78 replaceable), NIP-44 v2 encrypted
d-tag: bitspire-fees:<atm_pubkey_hex>
["p", atm_pubkey], signed by operator account
watermark: event.created_at (no envelope-level published_at)
Plaintext:
{ schema_version: 1,
cash_in_fee_fraction: …, sum ≤ 0.15
cash_out_fee_fraction: …, sum ≤ 0.15
components: { super_cash_in, super_cash_out,
operator_cash_in, operator_cash_out } }
Consumer-side invariants:
- Signature + author whitelist + watermark + clock-skew gates
- 15% per-direction hardcoded cap (defense in depth with sat's
producer-side refuse-to-publish at the same threshold)
- Consistency assert when `components` present: sum of super+operator
must equal each total within 1e-6; drift logs WARN + still applies
(totals are authoritative — see coord log §`07:33Z` and §`14:25Z`)
- Unknown top-level keys silently ignored (v2 forward-compat for
future promo additions); absent `schema_version` treated as v1
- Apply-mid-transaction defers to next tx by XState's context-snapshot
boundary; no explicit timer/lock code needed
Persistence (state.db schema v9→v10):
- New `fee_config` singleton row (id=1) with the totals, schema_version,
event_created_at watermark, and applied_at audit timestamp.
- New `meta.lastKnownFeeConfigCreatedAt` row — independent from the
cassette watermark per the d-tag-per-lifecycle convention.
- Super/operator components are NOT persisted on the ATM —
satmachineadmin is the canonical audit substrate per Layer 1 #38
(dumb-machine / smart-server split, see coord log §`07:56Z`). The
breakdown survives in the parser's receipt log line in journalctl
for offline forensics.
Fail-closed posture:
- First boot with no persisted config + no inbound event →
`initError = 'awaiting-fees'` → maintenance screen ("Awaiting fee
configuration from operator. Contact operator to publish initial
fee config."). Matches path-B `roster_required` posture.
- Persisted config present + relay unreachable → ATM operates with
the persisted values; subscriber catches up when relay returns.
Env-var fallback dropped:
- `VITE_CASH_IN_FEE` / `VITE_CASH_OUT_FEE` no longer read by the
Electron main process. Operator-config-over-Nostr is the single
source of truth — removes the env-vs-Nostr ambiguity surface.
- `parseFee` helper deleted (was its only caller).
Subscriber wired into all three init paths (Lightning-only,
direct-HAL, HAL-via-IPC) alongside the existing cassette-config
subscriber from #56. `onApply` callback receives just the totals
(components stay parser-side per the architectural split above).
IPC surface:
- state:get-fee-config → persisted singleton or null
- state:get-last-known-fee-config-created-at → watermark
- state:apply-fee-config → atomic upsert + watermark advance
Closesaiolabs/lamassu-next#57.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
`initialContext.cashInFeeFraction` / `cashOutFeeFraction` drop from
0.0333 / 0.0777 → 0. The state-machine no longer carries a fee
opinion; callers (the renderer's atm-store) are responsible for
supplying explicit fractions via `createATMMachine(..., options)`.
Why now: aiolabs/lamassu-next#57 makes the operator's Nostr-pushed
fee config the source of truth on the ATM. Keeping non-zero defaults
in the state machine would mean a misconfigured caller could silently
fall back to a 7.77% cash-out fee instead of failing closed into the
"awaiting fee configuration" maintenance screen.
Extracts `ATMMachineOptions` as a named interface (was inline). No
functional change to the option spread.
Updates the `should calculate sats amount from fiat with fee` test
to pass `cashOutFeeFraction: 0.0777` explicitly so it still exercises
the cash-out fee math; the post-refactor zero default would otherwise
land 50,000 sats instead of 53,885.

First test surface for the Electron + Vue 3 app — apps/machine has had
no tests until now (workspace packages cover state-machine, nostr-client,
clink, lnbits). Cassette config #56 shipped untested under the same
posture; #57 (operator fee config consumer) introduces enough load-
bearing parser + state-store logic to want unit coverage, so growing
the test substrate now.
Adds `test` / `test:watch` scripts + vitest devDep + minimal config
that picks up `src/**/*.test.ts` and `electron/**/*.test.ts`. No tests
land here — that comes with the feature commit.

Under path B (NOSTR_TRANSPORT_ROSTER_REQUIRED=true), lnbits's
roster-lookup override routes create_invoice to the operator's
wallet, but the subsequent subscribe_payments was scoping its
filter to the ATM's pre-override wallet_id. The dispatcher
AND-filters payment_hash + wallet_id, so the settlement on the
operator wallet was invisible to the subscription — bitspire
stayed in "Watching invoice" forever, dispense never fired.
Omit wallet_id on the single-invoice watcher: lnbits already
resolves the wallet from get_standalone_payment(payment_hash)
and ownership-checks against the auth'd account. Works pre/post-
override; payment_hash is the natural primary key for "wait for
THIS invoice" anyway.
Cash-out subscription site at services/lightning.ts:1008-1010
(production caller) + watchInvoice convenience helper at
packages/lnbits/src/client.ts:286-313 both flipped.
LNURL-withdraw subscription at services/lightning.ts:720
(filter: tag+link_id) is the symmetric case but pending lnbits
confirmation that the tag+link_id branch of _resolve_owner_wallet_id
exists alongside the payment_hash branch.

smoke surfaced the bug), 18:40Z (bitspire diagnosis), 18:50Z

Picks up aiolabs/atm-tui@3dffaf9 — cassettes table PK flips to position,
helpers operate by position, supports multiple cassettes with the same
denomination. Matches the lamassu-next v9 schema migration at bfd0b11.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Mirrors satmachineadmin's PR #30 v1.1 commits (df6e8e0..1cebefc). Three
load-bearing corrections from the v1.0 implementation:
1. **Wire shape flips from denomination-keyed to position-keyed**
(`{positions: {<pos>: {denomination, count}}}`). The original `#56`
spec was position-keyed; my `06:40Z` audit-and-flip was wrong on
both the load-bearingness of the ATM denom-PK invariant AND on the
operational requirement (per-slot denomination must be operator-
editable for swap-during-refill).
2. **Drop "one cassette per denomination" invariant.** Real production
machines load multiple cassettes with the same denomination for
cash-out throughput on a single bill class (4 × $20 cassettes on
Tejo/batm3 are normal). NO unique index on denomination.
3. **HAL refactor for per-position state + greedy distribution.** When
asked for N of denomination D, iterate matching bays in position
order draining greedy until the request is satisfied or all matching
bays empty. Surfaces "Insufficient inventory for denomination D:
short K" rather than crashing on the first under-stocked bay.
Schema migration v8 → v9: rebuild `cassettes` with `position INTEGER
PRIMARY KEY`, `denomination INTEGER NOT NULL`, `count INTEGER NOT NULL
DEFAULT 0`. SQLite create-copy-drop-rename per the v4→v5 precedent
(FKs off during, no data loss). Existing rows backfill column-by-column.
`setCassettes()` upserts `ON CONFLICT(position)`. `updateCassetteCount
(denomination, delta)` → `updateCassetteCountByPosition(position, delta)`
since the dispenser returns per-position results. `getInventory()`
boundary stays denomination-keyed (sums across matching bays) for
backwards compat with renderer callers.
HAL `inventory: Record<denom, count>` + `cassetteDenominations: number[]`
collapse into a single `bays: {position, denomination, count}[]` array.
Dispense per-bay note assignment + per-bay decrement on result. Bay
ordering by position throughout.
Operator-config consumer (`operator-config.ts`) flips both the apply
direction (`{positions: ...}` parse + validate position-set equality +
denom/count int checks, NO denom-uniqueness) and the bootstrap publish
direction (position-keyed payload encoding).
IPC type signatures updated in `preload.ts` + `types/electron.d.ts` for
both the new `OperatorCassettesPayload` shape and the per-position
`halReloadCassettes` argument.
`atm-tui` schema flip + handler updates land in a separate commit on
`aiolabs/atm-tui` (this commit's changes are limited to lamassu-next).
Bumping the atm-tui flake input on `deploy/server-deploy` (or the local
flake.lock here) after the atm-tui push reaches the sintra closure.
12/12 typecheck, 18/18 state-machine tests, 11/11 clink, 11/11 lnbits,

Wires the ATM-side consumer of operator-driven cassette config per
aiolabs/lamassu-next#56 v1. Operator → ATM only, with a one-shot ATM
bootstrap hello-event so satmachineadmin can auto-populate
`cassette_configs` rows on first boot.
Transport (decision rationale in coordination log 2026-05-30 entries):
- kind=30078 (NIP-78 replaceable), ["p", atm_npub]-tagged, ["d",
"bitspire-cassettes:<machine_id>"], NIP-44 v2 encrypted content,
authored by operator. Subscribed via filter
{kinds:[30078], "#p":[my_npub], "#d":[...], authors:OPERATOR_PUBKEYS}
- machine_id = ATM hex pubkey (no extra provisioning step)
Wire payload is denomination-keyed (per satmachineadmin's 06:40Z
audit of the ATM stack — every layer beneath the wire keys on
denomination, position is a sortable display column):
{ "denominations": { "<denom>": { "position": N, "count": M } } }
Validation:
- event signature + author in VITE_OPERATOR_PUBKEYS allowlist
- replay protection via meta.lastKnownConfigCreatedAt (drops events
re-delivered on relay reconnect or after restart)
- clock-skew defense: reject created_at > now + 60s
- denomination key set EXACTLY equal to state.db denominations
(no add/remove cassettes from the dashboard)
- per-row position positive int, count non-negative int
Apply in a single SQLite transaction (cassettes upsert by denomination
PK + meta watermark update), then hot-reload HAL via new IPC
`hal:reload-cassettes` so dispense math picks up the new layout
without restarting the bitspire service.
Bootstrap hello-event (one-shot):
- on init, if meta.bootstrapPublishedAt IS NULL AND cassettes
non-empty, publish kind=30078 with d=bitspire-cassettes-state:<id>,
encrypted to operator pubkey, signed by ATM
- on success set meta.bootstrapPublishedAt; on failure leave null and
retry next boot (best-effort; doesn't block service startup)
Schema v7 → v8: adds meta rows lastKnownConfigCreatedAt + bootstrap-
PublishedAt. Fresh installs at v8 seed via INSERT OR IGNORE.
HAL service grows setCassettes(cassettes) — closes + re-inits the
dispenser, rebuilds the inventory map + cassetteDenominations index.
Exposed as `hal:reload-cassettes` IPC + window.electronAPI.halReload-
Cassettes for the renderer.
Out of scope (v2 / separate issue):
- continuous ATM-state reverse-channel publish (dashboard
reconciliation + ✅/⏳ apply confirmation + safe "Add N bills" UX)
12/12 typecheck + 18/18 state-machine + 11/11 clink + 11/11 lnbits
suites pass.

Picks up aiolabs/atm-tui@2326e63 — DB path default now resolves to
/var/lib/bitspire/state.db (production layout), with a schema guard
that refuses stray files. Closes the silent-wrong-file footgun caught

Aligns lamassu-next with the canonical sat-amount vocabulary agreed
across lnbits/bitspire/satmachineadmin (satmachineadmin@d717a6e,
coordination log 2026-05-26T17:10Z):
- `feePercent` / `cashInFeePercent` / `cashOutFeePercent`
→ `feeFraction` / `cashInFeeFraction` / `cashOutFeeFraction`
(canonical: unit fraction in [0, 1], NEVER a percentage)
- `cashInFeeRate` / `cashOutFeeRate` (config option names)
→ `cashInFeeFraction` / `cashOutFeeFraction`
- `fee_percent` (wire field on Payment.extra + state.db column)
→ `fee_fraction`
Bug fix bundled with the rename:
`lightning.ts:780` previously stamped `Payment.extra.fee_percent =
context.feePercent * 100` (0.05 → 5.0). state.db stored the unit
fraction (0.05) but Payment.extra carried the percent (5.0) — 100×
divergence that any consumer reading Payment.extra computed fees
wrong by exactly 100×. Now stamps `fee_fraction` directly as unit
fraction. Display layers (atm-tui, view components) multiply by 100
themselves.
Defensive invariants added:
- `computeFeeSats` (atm store) throws if `feeFraction` outside [0, 1]
or if cash-in `feeSats > principalSats` (would mean negative payout)
- `recordTransaction` (state-store) throws on the same range
- state-machine + electron + Vue views propagate the rename
state.db migration v6 → v7: `ALTER TABLE transactions RENAME COLUMN
fee_percent TO fee_fraction`. Historical migrations preserved
verbatim (they wrote `fee_percent`, future installs see the same
sequence followed by the v7 rename).
12/12 typecheck + 18/18 state-machine tests green. Coordinated with
~/dev/bitspire/atm-tui (separate commit) reading `fee_fraction`
from the new column.

Tonight's Sintra re-flash surfaced two procedure gaps the doc didn't
cover. Burn them in so future-us doesn't rediscover them:
1. Step 0 (re-flash only): preserve .env + state.db before powering
off. The .env carries VITE_ATM_PRIVATE_KEY — without it LNbits
treats the reflashed unit as new and spawns a fresh wallet,
stranding the old wallet's balance. Also: push origin/dev +
push-cache.sh BEFORE flashing, or the 04:00 auto-upgrade either
fails to substitute or silently downgrades.
2. Step 5: e2fsck "No such file or directory" after parted resize.
Kernel re-read the partition table (lsblk shows mmcblk0p2) but
Alpine's udev didn't create the /dev/ node. partprobe and
blockdev --rereadpt don't fix it — they refresh the kernel's view,
not /dev/. Fix is udevadm trigger + settle, or mknod 179:N by
hand. Caught tonight, cost ~4 round-trips of confusion.
Step 7 split into first-time vs re-flash provisioning paths — the
re-flash path sources from the step-0 backup so the ATM keeps its
wallet identity. Also added optional state.db restore command.

The 24.05-era image was ~6 GB actual; the README's count=2200 (8.8 GB)
gave a small margin. The 25.11 image is 7.3 GB actual (linux-firmware-
zstd grew, plus the version churn) — count=2200 would now truncate.
Bump to count=2800 (~11.2 GB) and note that future bumps may need
another increase — image size is the right thing to check via

Was: weekly, no persistence. Problem: 15GB eMMC + ~7GB closure means
cross-release upgrades are always tight. Weekly cadence stacked up to
a week of generations under the 04:00 auto-upgrade. Persistent=false
also meant a Sintra powered off at 03:30 skipped GC until next week.
Now runs daily at 03:30, 30 min before the 04:00 nixos-upgrade so each
upgrade attempt gets the freshest headroom. 7d retention unchanged.
This is a periodic-cleanup fix only — cross-release in-place upgrades
on 15GB eMMC will still hit the disk-full wall (caught 2026-05-26 on
24.05 → 24.11). Reflash remains the answer there.

Closes aiolabs/lamassu-next#50. Builds on #49 (commit 0dcbe44):
isAuthenticServerEvent now Schnorr-verifies inbound events, so ev.id
is by construction the id of a server-signed event and can be used
as a dedup key without risk of attacker pre-poisoning.
Two layers:
1. Client-global `seenEventIds` (Set<string>, FIFO cap 1000) in
`LnbitsClient.handleReply`. Skips events whose id has been seen.
Catches exact-replay — relay re-delivers the same bytes after
reconnect, or any other source that emits a bit-identical event.
Without #49's guard, an attacker could pre-poison this set with
chosen ids; with the guard, every entry is a server-signed event.
2. Per-subscription `seenPaymentHashes` (Set<string>, FIFO cap 500)
on `ActiveSubscription`. Skips `onPush` invocations whose payment
hash has been seen on the same subscription. Catches logical
duplicates — server fan-out across two relays produces two
different ev.ids carrying the same payment_hash, which the
client-global ev.id layer can't dedup but the per-sub hash layer
does. Scoped per-sub so independent subscriptions seeing the same
hash for their own reasons still fire.
Why this matters in production: without dedup, a relay rebroadcast of
a settlement push would invoke `onPush` twice. The state machine's
`watchInvoice` callback resolves on the first push and unsubscribes,
but a race between the second push and the unsubscribe round-trip
could land a second `dispenseCash()` for the same cash-out — customer
walks away with double the cash. Per-sub `payment_hash` is the only
field guaranteed-unique per settlement (the customer's payment hash
is fixed at invoice creation), so it's the right dedup key.
5 new tests:
- forged event doesn't poison `seenEventIds` (proves guard + dedup
interact: a refactor that removes either #49's guard or this
patch's `seenEventIds.add()` ordering would fail this test)
- exact-replay: same event injected twice, callback fires once
- distinct ev.ids with same payment_hash, callback fires once
(per-sub hash dedup; ev.id dedup doesn't apply)
- distinct payment_hashes fire normally (negative dedup case)
- per-sub isolation: same hash on two subs fires both callbacks
Total: 11/11 lnbits package tests pass. Workspace typecheck clean.

Follow-up to commit 0dcbe44 (closesaiolabs/lamassu-next#49) addressing
two review notes from the bitspire session:
1. Integration test gap. The four unit tests on isAuthenticServerEvent
cover the predicate in isolation — a refactor that dropped the
`if (!isAuthenticServerEvent(...)) return` line from handleReply
would still pass them silently. Adds two integration tests that
exercise the full handleReply wiring through a mock NostrClient
that captures the subscribe callback:
- Forged event injected through the callback → pre-registered
pending entry's resolve is NOT called (asserts handleReply
short-circuited).
- Legitimate server-signed reply (NIP-44 v2 encrypted with
real keys) → pending entry's resolve IS called with the
decoded payload (positive sanity).
2. `@internal` JSDoc on isAuthenticServerEvent. The helper is exported
only so the unit tests can reach it directly; production callers
should go through handleReply. The annotation makes the intent
explicit and discourages accidental wider use.
6/6 tests pass. Workspace typecheck clean.

Clean step — all 8 nixosConfigurations evaluate without deprecation
warnings on 25.05.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
LnbitsClient.handleReply matched replies by request_id alone — no
verification that the inbound event was actually signed by the
configured LNbits server pubkey. The relay's subscription `authors`
filter is relay-honour, not relay-enforced; a malicious or buggy
relay could forward an event with the server's pubkey in the body
but signed by a different key (or with a tampered body whose id no
longer matches).
Adds `isAuthenticServerEvent(ev, expectedPubkey)`:
- `ev.pubkey === expectedPubkey` (explicit, not relying on filter)
- `verifyEvent(ev)` (catches sig/id/content tampering)
handleReply calls it before passing the event to decryptContentV2.
NIP-44 v2 already binds ciphertext to sender via ECDH, so a relay
without the server's nsec can't forge decryptable content — but
verifying the outer event keeps `ev.id` trustworthy for any
downstream dedup/logging code and matches the symmetric defence on
the server side (`nostr_transport/relay_pool.py:~320`) and on the
lnbits-bunker-client side (`aiolabs/lnbits` commit 4ebcd959,
`NsecBunkerAdminClient._match_response`).
Test `packages/lnbits/src/__tests__/client.test.ts` covers:
- legitimate server-signed event accepted
- event whose pubkey field doesn't match config rejected
- forged event (signed by attacker, pubkey overwritten to server)
rejected — recomputed id no longer matches stored id
- event with tampered content (id mismatch) rejected
Gotcha worth noting: `finalizeEvent` stamps `event[verifiedSymbol] = true`
to cache the verification result, and `{...ev}` spread copies symbol-
keyed properties. So forged/tampered events constructed via spread
inherit the cached `true` and `verifyEvent` short-circuits. The test
JSON-round-trips through `stripVerifiedCache` to drop the cache.

Adds a 5-minute expiration tag to every outbound RPC envelope. Belt-
and-suspenders with the handler-side max_age check (aiolabs/lnbits
e4b5bcd7) — the tag lets compliant relays drop expired events at the
relay layer before they reach LNbits, while the handler's own
time-bounds check defends against a stripped tag.

events) on the ATM emission side.

nixpkgs 24.11 made `pkgs.python3` an alias for Python 3.12, which
removed `distutils` from stdlib. node-gyp@9.4.1 (transitively pulled
in by better-sqlite3) still imports `distutils.version`, so the app
derivation failed with `ModuleNotFoundError: No module named
'distutils'` on the better-sqlite3 rebuild step.
Pin to python311 — still in 24.11 nixpkgs. Drop once pnpm-lock bumps
better-sqlite3 to a release whose node-gyp@10+ doesn't need distutils.

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.
All 8 nixosConfigurations (4 models × {live,installed}) evaluate
clean with zero deprecation warnings on 24.11.

Sibling-file convention: drop a logo-dark.png alongside logo.png in
/var/lib/bitspire/branding/ and the renderer uses it whenever the
effective color mode is dark, falling back to logo.png when absent.
No branding.json change — the file name itself is the contract.
Wiring:
- electron/main.ts:loadBranding() reads logo-dark.png and base64-encodes
it into logoDarkDataUrl on the IPC payload
- composables/useTheme.ts exposes an `isDark` computed that resolves
the 'system' colorMode via the prefers-color-scheme media query (and
reacts to OS-level dark-mode changes via the existing listener)
- composables/useBranding.ts switches logoUrl reactively based on isDark
- IdleView already binds to logoUrl — no template change needed

cachix push by default only walks the RUNTIME closure of the paths it
gets on stdin. Build-time inputs like fetchPnpmDeps tarballs are
consumed during a build and then thrown away — never referenced from
the final output — so they never make it into the cache.
This bites when an ATM has the cached runtime output for an older
version of bitspire-atm-app but then needs to rebuild it (e.g. because
a flake.nix change shifts the toplevel hash, cascading through to a
new app derivation). Sintra OOM-killed itself today (2026-05-25) doing
exactly this: 1.4 GB of pnpm install + node-headers on 1 GB of RAM.
Fix: query the .drv that produced each output path, then walk
`nix-store -qR --include-outputs <drv>` — that gives the full
build-time closure (every path needed to realize the build, including
fixed-output fetchers like fetchPnpmDeps). cachix push then uploads
all of them.
Cost: somewhat larger pushes, but the dev box has the headroom.
Benefit: ATM nixos-upgrade never falls into the rebuild-from-source
trap.

`./deploy/push-cache.sh sintra` was building+pushing `iso-sintra` while
the Sintra's auto-upgrade pulls `nixosConfigurations.sintra-installed`.
Result: the cache had the ISO closure but not the installed closure, so
every Sintra nixos-upgrade ran the substitution loop, came up empty for
small text-stitch derivations (nix.conf, etc, system-units), and bailed
with `local builds are disabled (max-jobs = 0)`. Caught when
re-provisioning the dev unit to the demo LNbits.
Symmetric fix:
- `sintra` now pushes `nixosConfigurations.sintra-installed.…toplevel`
(matches the douro/batm3 convention)
- New `sintra-live` target pushes the ISO (matches douro-live)
- `all` now includes `sintra-installed` (was silently missing)

Read /var/lib/bitspire/branding/{logo.png,branding.json} on startup and
apply across the renderer. branding.json may set title, theme (one of
the 6 built-ins or "custom"), and a custom_colors map (with optional
.dark overlay) — unset CSS vars fall back to gruvbox.
Wiring:
- electron/main.ts:loadBranding() reads + validates the JSON and
base64-encodes logo.png; surfaced via the existing get-config IPC
- composables/useBranding.ts holds reactive logoUrl/title refs and a
single setBranding() setter — the seam where #48's Nostr-event
source will eventually overlay the local-file source
- composables/useTheme.ts:applyBrandingTheme() handles built-in theme
swap and injects a <style#branding-custom-theme> block for custom
- IdleView binds :src/title; App.vue calls setBranding() before the
maintenance screen renders so "Under Service" wears operator branding
Provisioning: new deploy/nixos/provision-branding.sh rsyncs a local dir
to /var/lib/bitspire/branding/ via sudo-on-the-far-side and restarts
bitspire.service. The existing provision-atm.sh stays focused on .env.

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.

Default FIAT_CODE per-model (sintra=EUR, douro/tejo=GTQ, batm3=USD) to
match the flake's fiatCodeForModel table; both overridable via env var.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Follow-up to 138cd1a. Adds the customer-transacted fiat amount as a
top-level field on the kind-21000 Payment.extra payload, sourced
directly from `context.fiatCents` (the bill validator/dispenser
ledger — canonical record of what bills entered/exited the machine).
Why a separate field instead of letting the consumer divide:
principal_sats / exchange_rate
…is close but not equal to the bill-counted truth. It assumes the
commission was paid entirely in BTC (true today on cash-out) and
introduces sub-cent rounding from `floor()` in the principalSats
calc. The bill-validator number doesn't have those problems and is
the only authoritative record of what cash actually changed hands.
Belongs with the rest of the #44 metadata. Spec didn't enumerate it
originally; adding now before the field name locks in across the
fleet.
Cash-out invoices created via `lnbits.createInvoice()` now carry the
principal / commission / exchange-rate metadata satmachineadmin needs
to drive DCA distribution without back-deriving from a stored rate.
Closes the wire-format side of `aiolabs/lamassu-next#44`.
Wire payload (matches the canonical names agreed in #44 comments
#598/#599/#600 — `principal_sats` not `net_sats`, `fee_percent` not
`fee_pct`):
extra: {
source: 'bitspire',
type: 'cash_out',
txid: context.txid,
principal_sats: floor((fiatCents / 100) * exchangeRate),
fee_sats: max(0, satsAmount - principal_sats),
fee_percent: feePercent * 100,
exchange_rate: context.exchangeRate, // raw market rate, sats/fiat
currency: context.currency, // customer-paid currency
}
`bills` / `cassettes` deferred — they're meaningful for cash-in and
partial-dispense reconciliation, neither of which is wired on the
satmachineadmin side yet (#22, #3).
Plumbing:
- `ATMServices.generateInvoice` signature changes from
`(amountMsat: number) => Promise<string>` to
`(context: ATMContext) => Promise<string>`. The on-wire BOLT11
amount is derived inside the service as `satsAmount * 1000` msats;
the rest of the context drives the extra payload.
- State-machine `generatingInvoice` actor passes the full context
instead of just msats.
- Dev mock in `apps/machine/src/stores/atm.ts` updated to match.
All 18 state-machine tests pass. Typecheck clean across the app.
Two `// pragma: allowlist secret` markers added to lightning.ts on
existing doc-comment lines that mention "private key" — the dev-env
pre-commit secret scanner flagged them as false positives (every
prior commit touching this file had bypassed via --no-verify).
Cash-in (`generateLnurlWithdraw`) intentionally left alone for now —
satmachineadmin's listener doesn't handle the outbound LNURL-withdraw
flow yet (`aiolabs/satmachineadmin#22`), so stamping metadata it
won't read would be premature. Will land alongside that issue.
"Gross" was operator-vs-customer ambiguous (cash-out: customer's gross
payment = principal + commission, not the variable's value). atm-tui
already settled on "principal" for the same quantity (bitspire/atm-tui
src/db.zig:166-171, src/main.zig:98,716), and #44's Payment.extra
proposal will surface it as `principal_sats` on the kind-21000 wire.
Aligning the internal name removes one translation step across DB →
TUI → state machine → wire envelope.
Pure mechanical rename — no behavioral change. Also rewrites the
computeFeeSats JSDoc to drop the "gross"/"net" framing and document
the principalSats / on-wire satsAmount relationship explicitly.

Second + final batch of the doc refresh. README + CLAUDE went out in
8c9ae29; deploy/nixos/README + obsolete-flow flags in 924844f. This
commit covers everything left.
docs/machine-installation.md
Was describing a manual AppImage scp deploy + a `lamassu-kiosk`
systemd unit that hasn't been the deployment path for months.
Replaced with a high-level "what the pipeline does and why"
overview that points at deploy/nixos/README.md for the full
command-by-command walkthrough. Includes the BATM3 chassis-mod
note (custom Dell OptiPlex retrofit, not a stock Dell).
docs/architecture-comparison.md
Rewrote the comparison to be lamassu-server (≤ v8.1.5) vs bitSpire
(LNbits-backed) instead of the original lamassu-server vs LP-backed
lamassu-next framing. Updated the cash-out + cash-in flow diagrams
to show the actual nostr-transport path (LNbits-bundled nostrrelay
extension at ws://<host>:5001/nostrrelay/test, no separate strfry
container). Replaced the migration-path section with a softer
"when to choose what" framing that includes Lamassu's current
commercial offering as a legitimate third option. Added a header
pointer to the Acknowledgements section.
docs/business-model.md
Light touch-ups: Lightning.Pub → LNbits where it appeared, swapped
the [[ndebit-cash-in-flow]] link for [[architecture-comparison]],
noted the kind-30078 service beacon for availability broadcasts.
docs/device-configuration.md
Dropped "Lamassu" branding from the machine-model headings
(Sintra / tejo / douro / batm3 are referenced by hardware identity
here, not by Lamassu's product line). Added the Sintra-specific
ttyS4-vs-placeholder-ttyS1..3 gotcha we hard-learned during the
first flash. Corrected the BATM3 entry: stock GeneralBytes chassis
with a Dell OptiPlex 9030 AIO motherboard physically grafted in,
NOT a Dell out of the box. Updated the example /dev/ttyJ* symlink
output to match what a healthy Sintra actually shows.
docs/adr/001-hal-architecture.md
ADRs are historical artifacts — kept the original decision text
intact. Added a postscript noting:
- The package rename @lamassu/hal → @bitSpire/hal
- The v8.1.5 boundary on any lamassu-machine source-tree
references (Lamassu's 2024-01-26 license transition)
- That the "Remaining Work" list is complete and the first
successful Sintra hardware integration ran on 2026-05-13
.claude/skills/lightning-check.md
Rewrote end-to-end. Was Lightning.Pub-flavoured with CLINK kinds
21001/21002 as the primary flows; now validates the LNbits nostr-
transport surface (kind-21000 envelope, NIP-44 v2 encryption,
subscribe_payments filter discipline, lnurlw link composition).
Preserved a --clink mode for the still-live kind-21003 operator-
management surface. Includes a "what to check" rubric for cash-out
vs cash-in flows that mirrors the actual code in
apps/machine/src/services/lightning.ts.
.claude/skills/hal-check.md
Two pivots: (1) acknowledge ADR-001's TypeScript-not-Rust choice
and reframe all the safety checklists in TS-flavour (type safety,
discriminated unions, single-writer serial, bounded emitters)
instead of Rust-flavour (unsafe, borrow checker). (2) Add explicit
v8.1.5 provenance boundary plus a "forbidden operations" section
that prohibits diffing or porting from v8.1.6+ lamassu-machine
source. Updated the port-validation source-reference table to
list TS file paths under packages/hal/ instead of Rust paths.
.claude/skills/docs.md
@lamassu/* → @bitSpire/*. Replaced the Lightning.Pub mermaid
diagram with a current cash-out flow showing the nostr-transport
RPC + subscribe_payments push path. Left the createOffer noffer
example in the API-docs template section since it's illustrative
("here's what a good TSDoc block looks like") rather than current
reference documentation.
.claude/skills/test.md
One-line: @lamassu/nostr-client → @bitSpire/nostr-client in the
pnpm-filter example.
deploy/nixos/README.md
Single touch-up: clarified the douro/batm3 hardware-module comments
to reflect that BATM3 is a custom-installed Dell board in a
GeneralBytes BATM3 chassis (not a Dell OEM).
Files NOT touched in this sweep (intentionally):
- packages/hal/src/**/*.ts attribution comments — those reference
"lamassu-machine" in their port-source headers. Those are
factually accurate (the drivers ARE ported from there, up to
v8.1.5) and constitute necessary license/attribution metadata.
Editing them would erase the provenance trail.
- .claude/skills/{nostr-check,security}.md — already protocol-
neutral, no LP/lamassu references to clean up.

deploy/nixos/README.md was the most-stale doc in the tree: it still
talked about a `lamassu-atm` systemd unit, `/opt/lamassu-atm` paths,
nixos-install with a non-existent `lamassu-atm` flake output, and an
scp-the-built-electron-bundle workflow that hasn't been the deploy
path for many months. Replaced with a rewrite that documents the
actual current pipeline:
- File layout: bitspire-atm.nix (not lamassu-atm.nix), live.nix,
hardware/{douro,batm3,upboard}.nix, and the udev / helper scripts
- Build pipeline: `nix build .#disk-image-<model>` and the four
flake-output flavours per model (live config, installed config,
iso, disk-image)
- Full Sintra walkthrough end-to-end: prep a flashing USB on the
dev box, boot Alpine live on the Sintra, identify the eMMC,
dd with count= to skip the trailing USB padding, repair the
GPT secondary header + grow root with parted, poweroff, boot,
provision via provision-atm.sh. Every quirk we hit during the
first real flash is now baked in (mdev for /dev nodes, parted
Fix prompt, lbu-style notes).
- Runtime layout cheat-sheet: /var/lib/bitspire/.env (0600
lamassu:lamassu), state.db, /etc/bitspire/config.env, etc.
- Common-operations playbook: re-provision, nixos-rebuild switch
over SSH with --use-remote-sudo (much faster than reflashing),
journalctl filtering, hardware-side health checks.
- NixOS module reference for services.bitspire, including the
LNbits-flavoured options (relayUrl, lnbitsServerPubkey,
lnbitsHttpUrl) instead of the retired lightningPubUrl.
- Sintra-specific gotchas section: eMMC-via-sdhci-acpi, the
ttyS4 dispenser placement, the ttyS1..3 phantom-node issue.
- Security-notes section updated to reflect passwordless sudo
enabled for nixos-rebuild deploys, and the implications.
Auto-upgrade behaviour explained explicitly (the ?ref=dev pin) so
contributors understand why production ATMs on main don't pick up
dev branch changes.
docs/ndebit-cash-in-flow.md: added a header banner flagging the
document as historical — cash-in on dev is LNURL-withdraw +
subscribe_payments push, not ndebit. Original content kept as a
reference for any future revival of nostr-native cash-in.
docs/clink-protocol.md: same treatment — flagged as dormant on dev,
explaining which pieces still apply (kind-21003 management) and
which are unused (kinds 21001/21002). Protocol reference content
left intact since the wire format is unchanged upstream.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Both top-level docs were stale after the lamassu-next → bitSpire +
Lightning.Pub → LNbits migration shipped on this branch. They still
listed @lamassu/* package scopes, treated Lightning.Pub as the backend,
described cash-in as ndebit/CLINK, and pointed at removed packages.
README.md: rewritten end-to-end. Calls out the branch model (main vs
dev) so contributors don't accidentally affect production ATMs.
Documents the actual cash-out (BOLT11 + subscribe_payments by hash)
and cash-in (LNURL-withdraw + subscribe_payments by tag/link_id) wire
flows. Quick-start uses the dev compose's bundled LNbits with
nostr-transport + the LNbits-internal nostrrelay extension (the relay
endpoint is ws://<host>:5001/nostrrelay/test — no separate strfry
container, this was a pitfall during Sintra provisioning). Disk-image
deployment summary points at deploy/nixos/README for full details.
CLAUDE.md: rewritten to describe dev-branch reality. Lists actual
package names (@bitSpire/*), notes packages/lightning was deleted in
3d, calls out the LightningBackend adapter pattern in services/
lightning.ts, and gives an env-var reference table + a wire-envelope
crib for kind-21000. Sintra-specific hardware notes (UART layout,
initrd modules for the ACPI eMMC controller) bake in everything we
hard-learned during the first flash.
Both docs now include an Acknowledgements / Provenance section that:
- credits Lamassu Industries AG's open-source lamassu-machine /
lamassu-server (the v8.1.5 release line) as the prior art the
HAL drivers and state machine derive from — bitSpire wouldn't
exist without that foundation
- explicitly states Lamassu transitioned to a proprietary,
source-available "Appendix A SLA" on 2024-01-26 with v8.1.6+
gated behind a paid OSA subscription, and that bitSpire
incorporates no code from v8.1.6 or later
- declares bitSpire independent of Lamassu Industries AG
- in CLAUDE.md specifically: a hard rule that future contributors
(or future Claude runs) must not pull / port / copy code from
lamassu-machine at v8.1.6+; only the 8.1.5 tree is in-scope
License clarification: AGPL-3.0 (matches LNbits, which we link
against) — dropped the earlier "matches LNbits + lamassu-machine
pedigree" phrasing since lamassu-machine is no longer under a free
license.

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.
vue-tsc clean.

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.
Verified:

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).
