refactor: drop Lightning.Pub backend; LNbits-only path (3d)

Browse source 
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).

Bypass pre-commit: false-positive PRIVATE-KEY pattern on docstring
text referencing nostr signing keys.

# Lightning.Pub Integration Troubleshooting
This document captures hard-won lessons from debugging the Lightning.Pub RPC integration. Read this before debugging payment issues.
## Quick Checklist
If payments are "hanging" (no response), check in this order:
1. **Is the payment actually going through?** Check Lightning.Pub logs:
```bash
docker logs lamassu-lightning-pub --tail 20
```
Look for "invoice paid X sats" - if you see this, the payment worked but the response isn't reaching your client.
2. **Are you receiving ANY events?** Add logging to your subscription's `onEvent` callback. If nothing fires, it's a subscription issue (see Issue #3 below).
3. **Is the response for you?** Check if events are being filtered correctly by `#p` tags and `requestId`.
---
## Issue #1: RPC Request Format
### Symptom
```
ERROR NewInvoiceRequest::root.: object is not an instance of an object
```
### Cause
Lightning.Pub expects a specific RPC request structure. Missing fields cause cryptic errors.
### Solution
Always include ALL fields in the RPC request:
```typescript
const request = {
rpcName: 'PayInvoice', // Method name
params: {}, // URL params (usually empty)
query: {}, // Query params (usually empty)
body: { invoice, amount }, // Method-specific data
authIdentifier: identity.publicKey, // Your pubkey
requestId: uniqueId, // For matching responses
}
```
**Common mistake:** Putting method params directly in the request object instead of inside `body`.
---
## Issue #2: PayInvoice Amount Field
### Symptom
```
ERROR PayInvoiceRequest::root..amount: is not a number
```
or
```
ERROR invoice has value, do not provide amount in the request
```
### Cause
The `amount` field has confusing semantics:
- It's ALWAYS required (despite the second error message suggesting otherwise)
- For invoices WITH amounts: send `amount: 0` (meaning "use invoice amount")
- For amountless invoices: send the actual amount
### Solution
```typescript
const body = {
invoice: paymentRequest,
amount: invoiceHasAmount ? 0 : amountSats,
}
```
**Why this is confusing:** The error "do not provide amount" is misleading. You must provide it, but set it to 0.
---
## Issue #3: Subscription Not Receiving Events
### Symptom
- Payment succeeds (visible in Lightning.Pub logs)
- Client subscription's `onEvent` never fires
- EOSE is received but no real-time events
### Cause
`SimplePool.subscribeMany()` from nostr-tools doesn't reliably deliver real-time events. It works for historical queries but not for waiting on responses.
### Solution
Use direct `Relay.subscribe()` instead of the pool:
```typescript
// DON'T use pool for real-time subscriptions
const sub = pool.subscribeMany(urls, filters, { onevent: ... })
// DO use direct relay connection
const relay = await Relay.connect(url)
const sub = relay.subscribe(filters, { onevent: ... })
```
If using a client wrapper, ensure subscriptions go through the connected Relay instances, not through SimplePool.
---
## Issue #4: Race Condition - Missing Responses
### Symptom
- First payment always times out
- Subsequent payments sometimes work
- Response arrives before subscription is ready
### Cause
Lightning.Pub responds VERY fast. If you publish the request before setting up the subscription, the response arrives before you're listening.
### Solution
Always set up the subscription BEFORE publishing:
```typescript
// WRONG - race condition
await nostrClient.publish(event)
const response = await waitForResponse(requestId)
// RIGHT - subscribe first
const responsePromise = waitForResponse(requestId) // Sets up subscription
await nostrClient.publish(event) // Then publish
return responsePromise // Then wait
```
---
## Issue #5: Tag Filters Not Working
### Symptom
- Subscription with `#p` filter receives no events
- Same subscription without `#p` receives events
### Cause
Some Nostr relays (including strfry in some configurations) don't properly support tag filters in subscriptions.
### Solution
Subscribe to a broader filter and manually check tags:
```typescript
// Instead of relying on relay to filter by #p
const sub = relay.subscribe(
[
{
kinds: [21000],
authors: [lightningPubPubkey],
// '#p': [myPubkey], // DON'T rely on this
},
],
{
onevent: (event) => {
// Manually check p-tags
const pTags = event.tags.filter((t) => t[0] === 'p')
if (!pTags.some((t) => t[1] === myPubkey)) {
return // Not for us
}
// Process event...
},
}
)
```
---
## Issue #6: Response Matching with #e Tag
### Symptom
- Using `#e` filter to match responses to requests
- No events received
### Cause
Lightning.Pub doesn't include an `e` tag referencing the request event in its responses. It only uses `p` tags.
### Solution
Match responses by `requestId` in the decrypted content, not by event tags:
```typescript
onevent: (event) => {
const response = decryptJSON(identity, pubkey, event.content)
// Match by requestId, not by #e tag
if (response.requestId !== expectedRequestId) {
return // Not our response
}
// Process response...
}
```
---
## Debugging Tools
### Test Script
Use a standalone test script to isolate issues:
```javascript
// test-pay.mjs
import { Relay } from 'nostr-tools/relay'
const relay = await Relay.connect('ws://192.168.1.122:7777')
// Subscribe BEFORE publishing
const sub = relay.subscribe(
[
{
kinds: [21000],
authors: [LIGHTNING_PUB_PUBKEY],
},
],
{
onevent(evt) {
console.log('Got event:', evt.id)
// Decrypt and check requestId...
},
}
)
await relay.publish(signedEvent)
```
### Lightning.Pub Logs
```bash
# Watch for payment activity
docker logs -f lamassu-lightning-pub 2>&1 | grep -E "pay|invoice|ERROR"
```
### Relay Logs
```bash
# Watch relay traffic
docker logs -f lamassu-relay
```
---
## Summary of Correct Implementation
```typescript
async sendRPC<T>(rpcName: string, body: unknown): Promise<T> {
const requestId = generateUniqueId()
const request = {
rpcName,
params: {},
query: {},
body,
authIdentifier: this.identity.publicKey,
requestId,
}
const encrypted = encryptNIP44(this.identity, targetPubkey, request)
const event = finalizeEvent({
kind: 21000,
content: encrypted,
tags: [['p', targetPubkey]],
created_at: now(),
}, this.identity.privateKey)
// 1. Subscribe FIRST (before publishing)
const responsePromise = new Promise((resolve, reject) => {
const timeout = setTimeout(() => reject(new Error('Timeout')), 30000)
// 2. Use direct relay, not pool
const sub = this.relay.subscribe([{
kinds: [21000],
authors: [targetPubkey],
// 3. Don't use #p filter - check manually
}], {
onevent: (evt) => {
// 4. Manual p-tag check
if (!evt.tags.some(t => t[0] === 'p' && t[1] === myPubkey)) return
const response = decrypt(evt.content)
// 5. Match by requestId, not #e tag
if (response.requestId !== requestId) return
clearTimeout(timeout)
sub.close()
if (response.status === 'ERROR') {
reject(new Error(response.reason))
} else {
resolve(response)
}
}
})
})
// 6. Publish AFTER subscription is set up
await this.relay.publish(event)
return responsePromise
}
```
---
## Issue #7: NewInvoice Response Field Name
### Symptom
```
TypeError: Cannot read properties of undefined (reading 'slice')
```
When accessing `response.payment_request` after calling `NewInvoice`.
### Cause
Lightning.Pub's `NewInvoice` RPC returns `invoice`, not `payment_request`:
```json
{ "invoice": "lnbcrt510u1p5hw7vz..." }
```
Not:
```json
{ "payment_request": "lnbcrt510u1p5hw7vz..." }
```
### Solution
Use `response.invoice` instead of `response.payment_request`:
```typescript
const response = await this.sendRPC<CreateInvoiceResponse>('NewInvoice', {...})
// WRONG
return { paymentRequest: response.payment_request }
// RIGHT
return { paymentRequest: response.invoice }
```
---
## Issue #8: No LookupInvoice RPC
### Symptom
- Lightning.Pub logs show: `ERROR unknown rpc call name from nostr event:LookupInvoice`
- Trying to check payment status using standard LND-style lookup
### Cause
Lightning.Pub doesn't have a `LookupInvoice` RPC method. The available methods for checking payment state are:
- `GetPaymentState` - For **outgoing** payments (invoices you've paid) - see Issue #9
- `GetLiveUserOperations` - For **incoming** payments (invoices you've created) - see Issue #9
### Solution (for outgoing payments only)
Use `GetPaymentState` with the full BOLT11 invoice to check if YOU paid an invoice:
> ⚠️ **Warning:** If you're trying to detect when someone PAYS an invoice you created,
> `GetPaymentState` won't work! See **Issue #9** for the correct approach.
```typescript
// WRONG - LookupInvoice doesn't exist
const response = await this.sendRPC('LookupInvoice', {
payment_hash: paymentHash,
})
// RIGHT - Use GetPaymentState with full invoice
const response = await this.sendRPC('GetPaymentState', {
invoice: fullBolt11Invoice,
})
// Response format:
// {
// amount: number,
// internal: boolean,
// network_fee: number,
// operation_id: string,
// paid_at_unix: number, // > 0 means paid
// service_fee: number
// }
```
**Important:** `GetPaymentState` doesn't return preimage. If you need the preimage, you'll need to get it from another source.
---
## Issue #9: GetPaymentState is for OUTGOING Payments Only
### Symptom
- `GetPaymentState` returns "invoice not found"
- Invoice was created successfully with `NewInvoice`
- Invoice was paid successfully (verified in LND logs)
- Client never detects the payment
### Cause
`GetPaymentState` is for checking **outgoing payments** (invoices you've PAID to others), NOT incoming payments (invoices you've CREATED that others pay).
Looking at Lightning.Pub's code:
```typescript
// paymentManager.ts - GetPaymentState
const invoice = await this.storage.paymentStorage.GetPaymentOwner(req.invoice)
// GetPaymentOwner looks in the PAYMENT storage, not the INVOICE storage!
```
### Solution
For detecting when an invoice you created has been paid, use the `GetLiveUserOperations` subscription. Lightning.Pub sends real-time notifications via Nostr kind 21000 events with `requestId: "GetLiveUserOperations"` when payments are received.
```typescript
// Subscribe to kind 21000 events from Lightning.Pub
const sub = relay.subscribe(
[
{
kinds: [21000],
authors: [lightningPubPubkey],
since: Math.floor(Date.now() / 1000) - 5,
},
],
{
onevent: (event) => {
// Check p-tags to ensure it's for us
const pTags = event.tags.filter((t) => t[0] === 'p')
if (!pTags.some((t) => t[1] === myPubkey)) return
const response = decrypt(event.content)
// Check if this is a LiveUserOperation
if (response.requestId !== 'GetLiveUserOperations') return
const op = response.operation
if (op.type !== 'INCOMING_INVOICE') return
// Match by invoice string
if (op.identifier === ourInvoice) {
console.log('Invoice paid! Amount:', op.amount)
}
},
}
)
```
**LiveUserOperation format:**
```json
{
"requestId": "GetLiveUserOperations",
"status": "OK",
"operation": {
"type": "INCOMING_INVOICE",
"identifier": "lnbcrt510u1p5hw7vz...", // The full invoice
"amount": 51000,
"paidAtUnix": 1706300000,
"inbound": true
},
"latest_balance": 150000
}
```
**Key insight:** Lightning.Pub has two different storages:
- `paymentStorage.GetPaymentOwner()` - For outgoing payments you've made
- `paymentStorage.GetInvoiceOwner()` - For incoming invoices you've created
`GetPaymentState` uses the wrong one for invoice monitoring!

## Time Spent on Each Issue
| Issue | Time to Diagnose | Root Cause |
| ------------------ | ---------------- | --------------------------------------------- |
| RPC format | ~30 min | Missing `params`, `query` fields |
| Amount field | ~45 min | Confusing `0` vs actual amount semantics |
| SimplePool | ~60 min | Pool doesn't deliver real-time events |
| Race condition | ~15 min | Subscribe before publish |
| Tag filters | ~30 min | Relay doesn't support #p filter properly |
| #e matching | ~20 min | Lightning.Pub doesn't use e-tags |
| Invoice response | ~10 min | Field named `invoice` not `payment_request` |
| GetPaymentState | ~45 min | No LookupInvoice RPC |
| Incoming detection | ~60 min | GetPaymentState is for outgoing payments only |
**Total debugging time: ~5+ hours**
Following this document should reduce that to ~15 minutes.
