Accounting +Analysis: Net Settlement Entry Pattern

+

Date: 2025-01-12 Prepared By: +Senior Accounting Review Subject: Libra Extension - +Lightning Payment Settlement Entries Status: Technical +Review

+
+

Executive Summary

+

This document provides a professional accounting assessment of +Libra’s net settlement entry pattern used for recording Lightning +Network payments that settle fiat-denominated receivables. The analysis +identifies areas where the implementation deviates from traditional +accounting best practices and provides specific recommendations for +improvement.

+

Key Findings: - ✅ Double-entry integrity maintained +- ✅ Functional for intended purpose - ❌ Zero-amount postings violate +accounting principles - ❌ Redundant satoshi tracking - ❌ No exchange +gain/loss recognition - ⚠️ Mixed currency approach lacks clear +hierarchy

+
+

Background: The Technical +Challenge

+

Libra operates as a Lightning Network-integrated accounting system +for collectives (co-living spaces, makerspaces). It faces a unique +accounting challenge:

+

Scenario: User creates a receivable in EUR (e.g., +€200 for room rent), then pays via Lightning Network in satoshis +(225,033 sats).

+

Challenge: Record the payment while: 1. Clearing the +exact EUR receivable amount 2. Recording the exact satoshi amount +received 3. Handling cases where users have both receivables (owe +Libra) and payables (Libra owes them) 4. Maintaining Beancount +double-entry balance

+
+

Current Implementation

+

Transaction Example

Code Implementation

+

Location: +beancount_format.py:739-760

+
# Build postings for net settlement
+postings = [
+    {
+        "account": payment_account,
+        "amount": f"{abs(amount_sats)} SATS @@ {abs(net_fiat_amount):.2f} {fiat_currency}",
+        "meta": {"payment-hash": payment_hash} if payment_hash else {}
+    },
+    {
+        "account": receivable_account,
+        "amount": f"-{abs(total_receivable_fiat):.2f} {fiat_currency}",
+        "meta": {"sats-equivalent": str(abs(amount_sats))}
+    },
+    {
+        "account": payable_account,
+        "amount": f"{abs(total_payable_fiat):.2f} {fiat_currency}",
+        "meta": {}
+    }
+]
+

Three-Posting Structure: 1. Lightning +Account: Records SATS received with @@ total price +notation 2. Receivable Account: Clears EUR receivable +with sats-equivalent metadata 3. Payable Account: +Clears any outstanding EUR payables (often 0.00)

+
+

Accounting Issues Identified

+

Issue 1: Zero-Amount Postings

+

Problem: The third posting often records +0.00 EUR when no payable exists.

+
Liabilities:Payable:User-375ec158     0.00 EUR
+

Why This Is Wrong: - Zero-amount postings have no +economic substance - Clutters the journal with non-events - Violates the +principle of materiality (GAAP Concept Statement 2) - Makes auditing +more difficult (reviewers must verify why zero amounts exist)

+

Accounting Principle Violated: > “Transactions +should only include postings that represent actual economic events or +changes in account balances.”

+

Impact: Low severity, but unprofessional +presentation

+

Recommendation:

+
# Make payable posting conditional
+postings = [
+    {"account": payment_account, "amount": ...},
+    {"account": receivable_account, "amount": ...}
+]
+
+# Only add payable posting if there's actually a payable
+if total_payable_fiat > 0:
+    postings.append({
+        "account": payable_account,
+        "amount": f"{abs(total_payable_fiat):.2f} {fiat_currency}",
+        "meta": {}
+    })
+
+

Issue 2: Redundant Satoshi +Tracking

+

Problem: Satoshis are tracked in TWO places in the +same transaction:

+
    +

  1. Position Amount (via @@ +notation):

    +
    Assets:Bitcoin:Lightning  225033 SATS @@ 200.00 EUR
    2. +

  2. Metadata (sats-equivalent):

    +
    Assets:Receivable:User-375ec158  -200.00 EUR
+  sats-equivalent: "225033"
    3. +
+

Why This Is Problematic: - The @@ +notation already records the exact satoshi amount - Beancount’s price +database stores this relationship - Metadata becomes redundant for this +specific posting - Increases storage and potential for inconsistency

+

Technical Detail:

+

The @@ notation means “total price” and Beancount +converts it to per-unit price:

+
; You write:
+Assets:Bitcoin:Lightning  225033 SATS @@ 200.00 EUR
+
+; Beancount stores:
+Assets:Bitcoin:Lightning  225033 SATS @ 0.0008887585... EUR
+; (where 200.00 / 225033 = 0.0008887585...)
+

Beancount can query this:

+
SELECT account, sum(convert(position, SATS))
+WHERE account = 'Assets:Bitcoin:Lightning'
+

Recommendation:

+

Choose ONE approach consistently:

+

Option A - Use @ notation (Beancount standard):

+
Assets:Bitcoin:Lightning           225033 SATS @@ 200.00 EUR
+  payment-hash: "8d080ec4..."
+Assets:Receivable:User-375ec158   -200.00 EUR
+  ; No sats-equivalent needed here
+

Option B - Use EUR positions with metadata (Libra’s +current approach):

+
Assets:Bitcoin:Lightning           200.00 EUR
+  sats-received: "225033"
+  payment-hash: "8d080ec4..."
+Assets:Receivable:User-375ec158   -200.00 EUR
+  sats-cleared: "225033"
+

Don’t: Mix both in the same transaction (current +implementation)

+
+

Issue 3: No Exchange +Gain/Loss Recognition

+

Problem: When receivables are denominated in one +currency (EUR) and paid in another (SATS), exchange rate fluctuations +create gains or losses that should be recognized.

+

Example Scenario:

+
Day 1 - Receivable Created:
+  200 EUR = 225,033 SATS (rate: 1,125.165 sats/EUR)
+
+Day 5 - Payment Received:
+  225,033 SATS = 199.50 EUR (rate: 1,127.682 sats/EUR)
+  Exchange rate moved unfavorably
+
+Economic Reality: 0.50 EUR LOSS
+

Current Implementation: Forces balance by +calculating the @ rate to make it exactly 200 EUR:

+
Assets:Bitcoin:Lightning  225033 SATS @ 0.000888... EUR  ; = exactly 200.00 EUR
+

This hides the exchange variance by treating the +payment as if it was worth exactly the receivable amount.

+

GAAP/IFRS Requirement:

+

Under both US GAAP (ASC 830) and IFRS (IAS 21), exchange gains and +losses on monetary items (like receivables) should be recognized in the +period they occur.

+

Proper Accounting Treatment:

+
2025-11-12 * "Lightning payment with exchange loss"
+  Assets:Bitcoin:Lightning           225033 SATS @ 0.000886... EUR
+    ; Market rate at payment time = 199.50 EUR
+  Expenses:Foreign-Exchange-Loss     0.50 EUR
+  Assets:Receivable:User-375ec158   -200.00 EUR
+

Impact: Moderate severity - affects financial +statement accuracy

+

Why This Matters: - Tax reporting may require +exchange gain/loss recognition - Financial statements misstate true +economic results - Auditors would flag this as a compliance issue - +Cannot accurately calculate ROI or performance metrics

+
+

Issue 4: Semantic +Misuse of Price Notation

+

Problem: The @ notation in Beancount +represents acquisition cost, not settlement +value.

+

Current Usage:

+
Assets:Bitcoin:Lightning  225033 SATS @ 0.000888... EUR
+

What this notation means in accounting: “We +purchased 225,033 satoshis at a cost of 0.000888 EUR +per satoshi”

+

What actually happened: “We +received 225,033 satoshis as payment for a debt”

+

Economic Difference: - Purchase: +You exchange cash for an asset (buying Bitcoin) - Payment +Receipt: You receive an asset in settlement of a receivable

+

Accounting Substance vs. Form: - +Form: The transaction looks like a Bitcoin purchase - +Substance: The transaction is actually a receivable +collection

+

GAAP Principle (ASC 105-10-05): > “Accounting +should reflect the economic substance of transactions, not merely their +legal form.”

+

Why This Creates Issues:

+
    +
  1. Cost Basis Tracking: For tax purposes, the “cost” +of Bitcoin received as payment should be its fair market value at +receipt, not the receivable amount
    2. +
  2. Price Database Pollution: Beancount’s price +database now contains “prices” that aren’t real market prices
    3. +
  3. Auditor Confusion: An auditor reviewing this would +question why purchase prices don’t match market rates
    4. +
+

Proper Accounting Approach:

+
; Approach 1: Record at fair market value
+Assets:Bitcoin:Lightning           225033 SATS @ 0.000886... EUR
+  ; Using actual market price at time of receipt
+  acquisition-type: "payment-received"
+Revenue:Exchange-Gain              0.50 EUR
+Assets:Receivable:User-375ec158   -200.00 EUR
+
+; Approach 2: Don't use @ notation at all
+Assets:Bitcoin:Lightning           200.00 EUR
+  sats-received: "225033"
+  fmv-at-receipt: "199.50 EUR"
+Assets:Receivable:User-375ec158   -200.00 EUR
+
+

Issue 5: Misnamed +Function and Incorrect Usage

+

Problem: Function is called +format_net_settlement_entry, but it’s used for simple +payments that aren’t true net settlements.

+

Example from User’s Transaction: - Receivable: +200.00 EUR - Payable: 0.00 EUR - Net: 200.00 EUR (this is just a +payment, not a settlement)

+

Accounting Terminology:

+ +

When Net Settlement is Appropriate:

+
User owes Libra:    555.00 EUR (receivable)
+Libra owes User:     38.00 EUR (payable)
+Net amount due:      517.00 EUR (true settlement)
+

Proper three-posting entry:

+
Assets:Bitcoin:Lightning           565251 SATS @@ 517.00 EUR
+Assets:Receivable:User            -555.00 EUR
+Liabilities:Payable:User            38.00 EUR
+; Net: 517.00 = -555.00 + 38.00 ✓
+

When Two Postings Suffice:

+
User owes Libra:    200.00 EUR (receivable)
+Libra owes User:      0.00 EUR (no payable)
+Amount due:          200.00 EUR (simple payment)
+

Simpler two-posting entry:

+
Assets:Bitcoin:Lightning           225033 SATS @@ 200.00 EUR
+Assets:Receivable:User            -200.00 EUR
+

Best Practice: Use the simplest journal entry +structure that accurately represents the transaction.

+

Recommendation: 1. Rename function to +format_payment_entry or +format_receivable_payment_entry 2. Create separate +format_net_settlement_entry for true netting scenarios 3. +Use conditional logic to choose 2-posting vs 3-posting based on whether +both receivables AND payables exist

+
+

Traditional Accounting +Approaches

+

Approach +1: Record Bitcoin at Fair Market Value (Tax Compliant)

+
2025-11-12 * "Bitcoin payment from user 375ec158"
+  Assets:Bitcoin:Lightning           199.50 EUR
+    sats-received: "225033"
+    fmv-per-sat: "0.000886 EUR"
+    cost-basis: "199.50 EUR"
+    payment-hash: "8d080ec4..."
+  Revenue:Exchange-Gain              0.50 EUR
+    source: "cryptocurrency-receipt"
+  Assets:Receivable:User-375ec158   -200.00 EUR
+

Pros: - ✅ Tax compliant (establishes cost basis) - +✅ Recognizes exchange gain/loss - ✅ Uses actual market rates - ✅ +Audit trail for cryptocurrency receipts

+

Cons: - ❌ Requires real-time price feeds - ❌ +Creates taxable events

+
+

Approach 2: +Simplified EUR-Only Ledger (No SATS Positions)

+
2025-11-12 * "Bitcoin payment from user 375ec158"
+  Assets:Bitcoin:Lightning           200.00 EUR
+    sats-received: "225033"
+    sats-rate: "1125.165"
+    payment-hash: "8d080ec4..."
+  Assets:Receivable:User-375ec158   -200.00 EUR
+

Pros: - ✅ Simple and clean - ✅ EUR positions match +accounting reality - ✅ SATS tracked in metadata for reference - ✅ No +artificial price notation

+

Cons: - ❌ SATS not queryable via Beancount +positions - ❌ Requires metadata parsing for SATS balances

+
+

Approach +3: True Net Settlement (When Both Obligations Exist)

+
2025-11-12 * "Net settlement via Lightning"
+  ; User owes 555 EUR, Libra owes 38 EUR, net: 517 EUR
+  Assets:Bitcoin:Lightning           517.00 EUR
+    sats-received: "565251"
+  Assets:Receivable:User-375ec158   -555.00 EUR
+  Liabilities:Payable:User-375ec158   38.00 EUR
+

When to Use: Only when both +receivables and payables exist and you’re truly netting them.

+
+

Recommendations

+

Priority 1: Immediate +Fixes (Easy Wins)

+

1.1 Remove Zero-Amount +Postings

+

File: beancount_format.py:739-760

+

Current Code:

+
postings = [
+    {...},  # Lightning
+    {...},  # Receivable
+    {       # Payable (always included, even if 0.00)
+        "account": payable_account,
+        "amount": f"{abs(total_payable_fiat):.2f} {fiat_currency}",
+        "meta": {}
+    }
+]
+

Fixed Code:

+
postings = [
+    {
+        "account": payment_account,
+        "amount": f"{abs(amount_sats)} SATS @@ {abs(net_fiat_amount):.2f} {fiat_currency}",
+        "meta": {"payment-hash": payment_hash} if payment_hash else {}
+    },
+    {
+        "account": receivable_account,
+        "amount": f"-{abs(total_receivable_fiat):.2f} {fiat_currency}",
+        "meta": {"sats-equivalent": str(abs(amount_sats))}
+    }
+]
+
+# Only add payable posting if there's actually a payable to clear
+if total_payable_fiat > 0:
+    postings.append({
+        "account": payable_account,
+        "amount": f"{abs(total_payable_fiat):.2f} {fiat_currency}",
+        "meta": {}
+    })
+

Impact: Cleaner journal, professional presentation, +easier auditing

+
+

1.2 Choose One SATS Tracking +Method

+

Decision Required: Select either position-based OR +metadata-based satoshi tracking.

+

Option A - Keep Metadata Approach (recommended for +Libra):

+
# In format_net_settlement_entry()
+postings = [
+    {
+        "account": payment_account,
+        "amount": f"{abs(net_fiat_amount):.2f} {fiat_currency}",  # EUR only
+        "meta": {
+            "sats-received": str(abs(amount_sats)),
+            "payment-hash": payment_hash
+        }
+    },
+    {
+        "account": receivable_account,
+        "amount": f"-{abs(total_receivable_fiat):.2f} {fiat_currency}",
+        "meta": {"sats-cleared": str(abs(amount_sats))}
+    }
+]
+

Option B - Use Position-Based Tracking:

+
# Remove sats-equivalent metadata entirely
+postings = [
+    {
+        "account": payment_account,
+        "amount": f"{abs(amount_sats)} SATS @@ {abs(net_fiat_amount):.2f} {fiat_currency}",
+        "meta": {"payment-hash": payment_hash}
+    },
+    {
+        "account": receivable_account,
+        "amount": f"-{abs(total_receivable_fiat):.2f} {fiat_currency}",
+        # No sats-equivalent needed - queryable via price database
+    }
+]
+

Recommendation: Choose Option A (metadata) for +consistency with Libra’s architecture.

+
+

1.3 Rename Function for +Clarity

+

File: beancount_format.py

+

Current: +format_net_settlement_entry()

+

New: format_receivable_payment_entry() +or format_payment_settlement_entry()

+

Rationale: More accurately describes what the +function does (processes payments, not always net settlements)

+
+

Priority 2: +Medium-Term Improvements (Compliance)

+

2.1 Add Exchange Gain/Loss +Tracking

+

File: tasks.py:259-276 (get balance and +calculate settlement)

+

New Logic:

+
# Get user's current balance
+balance = await fava.get_user_balance(user_id)
+fiat_balances = balance.get("fiat_balances", {})
+total_fiat_balance = fiat_balances.get(fiat_currency, Decimal(0))
+
+# Calculate expected fiat value of SATS payment at current market rate
+market_rate = await get_current_sats_eur_rate()  # New function needed
+market_value = Decimal(amount_sats) * market_rate
+
+# Calculate exchange variance
+receivable_amount = abs(total_fiat_balance) if total_fiat_balance > 0 else Decimal(0)
+exchange_variance = market_value - receivable_amount
+
+# If variance is material (> 1 cent), create exchange gain/loss posting
+if abs(exchange_variance) > Decimal("0.01"):
+    # Add exchange gain/loss to postings
+    if exchange_variance > 0:
+        # Gain: payment worth more than receivable
+        exchange_account = "Revenue:Foreign-Exchange-Gain"
+    else:
+        # Loss: payment worth less than receivable
+        exchange_account = "Expenses:Foreign-Exchange-Loss"
+
+    # Include in entry creation
+    exchange_posting = {
+        "account": exchange_account,
+        "amount": f"{abs(exchange_variance):.2f} {fiat_currency}",
+        "meta": {
+            "sats-amount": str(amount_sats),
+            "market-rate": str(market_rate),
+            "receivable-amount": str(receivable_amount)
+        }
+    }
+

Benefits: - ✅ Tax compliance - ✅ Accurate +financial reporting - ✅ Audit trail for cryptocurrency gains/losses - +✅ Regulatory compliance (GAAP/IFRS)

+
+

2.2 +Implement True Net Settlement vs. Simple Payment Logic

+

File: tasks.py or new +payment_logic.py

+
async def create_payment_entry(
+    user_id: str,
+    amount_sats: int,
+    fiat_amount: Decimal,
+    fiat_currency: str,
+    payment_hash: str
+):
+    """
+    Create appropriate payment entry based on user's balance situation.
+    Uses 2-posting for simple payments, 3-posting for net settlements.
+    """
+    # Get user balance
+    balance = await fava.get_user_balance(user_id)
+    fiat_balances = balance.get("fiat_balances", {})
+    total_balance = fiat_balances.get(fiat_currency, Decimal(0))
+
+    receivable_amount = Decimal(0)
+    payable_amount = Decimal(0)
+
+    if total_balance > 0:
+        receivable_amount = total_balance
+    elif total_balance < 0:
+        payable_amount = abs(total_balance)
+
+    # Determine entry type
+    if receivable_amount > 0 and payable_amount > 0:
+        # TRUE NET SETTLEMENT: Both obligations exist
+        return await format_net_settlement_entry(
+            user_id=user_id,
+            amount_sats=amount_sats,
+            receivable_amount=receivable_amount,
+            payable_amount=payable_amount,
+            fiat_amount=fiat_amount,
+            fiat_currency=fiat_currency,
+            payment_hash=payment_hash
+        )
+    elif receivable_amount > 0:
+        # SIMPLE RECEIVABLE PAYMENT: Only receivable exists
+        return await format_receivable_payment_entry(
+            user_id=user_id,
+            amount_sats=amount_sats,
+            receivable_amount=receivable_amount,
+            fiat_amount=fiat_amount,
+            fiat_currency=fiat_currency,
+            payment_hash=payment_hash
+        )
+    else:
+        # PAYABLE PAYMENT: Libra paying user (different flow)
+        return await format_payable_payment_entry(...)
+
+

Priority 3: +Long-Term Architectural Decisions

+

3.1 Establish Primary +Currency Hierarchy

+

Current Issue: Mixed approach (EUR positions with +SATS metadata, but also SATS positions with @ notation)

+

Decision Required: Choose ONE of the following +architectures:

+

Architecture A - EUR Primary, SATS Secondary +(recommended):

+
; All positions in EUR, SATS in metadata
+2025-11-12 * "Payment"
+  Assets:Bitcoin:Lightning           200.00 EUR
+    sats-received: "225033"
+  Assets:Receivable:User            -200.00 EUR
+    sats-cleared: "225033"
+

Architecture B - SATS Primary, EUR Secondary:

+
; All positions in SATS, EUR in metadata
+2025-11-12 * "Payment"
+  Assets:Bitcoin:Lightning           225033 SATS
+    eur-value: "200.00"
+  Assets:Receivable:User            -225033 SATS
+    eur-cleared: "200.00"
+

Recommendation: Architecture A (EUR primary) +because: 1. Most receivables created in EUR 2. Financial reporting +requirements typically in fiat 3. Tax obligations calculated in fiat 4. +Aligns with current Libra metadata approach

+
+

3.2 +Consider Separate Ledger for Cryptocurrency Holdings

+

Advanced Approach: Separate cryptocurrency movements +from fiat accounting

+

Main Ledger (EUR-denominated):

+
2025-11-12 * "Payment received from user"
+  Assets:Bitcoin-Custody:User-375ec158  200.00 EUR
+  Assets:Receivable:User-375ec158      -200.00 EUR
+

Cryptocurrency Sub-Ledger (SATS-denominated):

+
2025-11-12 * "Lightning payment received"
+  Assets:Bitcoin:Lightning:Libra    225033 SATS
+  Assets:Bitcoin:Custody:User-375ec  225033 SATS
+

Benefits: - ✅ Clean separation of concerns - ✅ +Cryptocurrency movements tracked independently - ✅ Fiat accounting +unaffected by Bitcoin volatility - ✅ Can generate separate financial +statements

+

Drawbacks: - ❌ Increased complexity - ❌ +Reconciliation between ledgers required - ❌ Two sets of books to +maintain

+
+

Testing Requirements

+

Test Case 1: +Simple Receivable Payment (No Payable)

+

Setup: - User has receivable: 200.00 EUR - User has +payable: 0.00 EUR - User pays: 225,033 SATS

+

Expected Entry (after fixes):

+
2025-11-12 * "Lightning payment from user"
+  Assets:Bitcoin:Lightning           200.00 EUR
+    sats-received: "225033"
+    payment-hash: "8d080ec4..."
+  Assets:Receivable:User            -200.00 EUR
+    sats-cleared: "225033"
+

Verify: - ✅ Only 2 postings (no zero-amount +payable) - ✅ Entry balances - ✅ SATS tracked in metadata - ✅ User +balance becomes 0 (both EUR and SATS)

+
+

Test Case 2: True Net +Settlement

+

Setup: - User has receivable: 555.00 EUR - User has +payable: 38.00 EUR - Net owed: 517.00 EUR - User pays: 565,251 SATS +(worth 517.00 EUR)

+

Expected Entry:

+
2025-11-12 * "Net settlement via Lightning"
+  Assets:Bitcoin:Lightning           517.00 EUR
+    sats-received: "565251"
+    payment-hash: "abc123..."
+  Assets:Receivable:User            -555.00 EUR
+    sats-portion: "565251"
+  Liabilities:Payable:User            38.00 EUR
+

Verify: - ✅ 3 postings (receivable + payable +cleared) - ✅ Net amount = receivable - payable - ✅ Both balances +become 0 - ✅ Mathematically balanced

+
+

Test Case 3: Exchange +Gain/Loss (Future)

+

Setup: - User has receivable: 200.00 EUR (created at +1,125 sats/EUR) - User pays: 225,033 SATS (now worth 199.50 EUR at +market) - Exchange loss: 0.50 EUR

+

Expected Entry (with exchange tracking):

+
2025-11-12 * "Lightning payment with exchange loss"
+  Assets:Bitcoin:Lightning           199.50 EUR
+    sats-received: "225033"
+    market-rate: "0.000886"
+  Expenses:Foreign-Exchange-Loss     0.50 EUR
+  Assets:Receivable:User            -200.00 EUR
+

Verify: - ✅ Bitcoin recorded at fair market value - +✅ Exchange loss recognized - ✅ Receivable cleared at book value - ✅ +Entry balances

+
+

Professional Assessment

+

Is this “best practice” accounting? +No, this implementation deviates from traditional +accounting standards in several ways.

+

Is it acceptable for Libra’s use case? Yes, +with modifications, it’s a reasonable pragmatic solution for a +novel problem (cryptocurrency payments of fiat debts).

+

Critical improvements needed: 1. ✅ Remove +zero-amount postings (easy fix, professional presentation) 2. ✅ +Implement exchange gain/loss tracking (required for compliance) 3. ✅ +Separate payment vs. settlement logic (accuracy and clarity)

+

The fundamental challenge: Traditional accounting +wasn’t designed for this scenario. There is no established “standard” +for recording cryptocurrency payments of fiat-denominated receivables. +Libra’s approach is functional, but should be refined to align better +with accounting principles where possible.

+

Next Steps

+
    +
  1. Week 1: Implement Priority 1 fixes (remove zero +postings, rename function)
    2. +
  2. Week 2-3: Design and implement exchange gain/loss +tracking
    3. +
  3. Week 4: Add payment vs. settlement logic
    4. +
  4. Ongoing: Monitor regulatory guidance on +cryptocurrency accounting
    5. +

The docstring example -assumes `net_fiat == total_receivable − total_payable`. But -`tasks.py:251-258` sets `total_receivable = total_prior_balance` and -`net_fiat = invoice_fiat_amount` — only equal when the user paid the -full balance. Any partial payment ships unbalanced postings; Beancount -will reject or apply tolerance silently. - -**Fix:** add `assert abs(net_fiat − (receivable − payable)) <= 0.005` -inside the formatter and raise on violation. Then fix the caller in -`tasks.py:218-322` to settle only what the payment covers (likely a -two-posting `DR Lightning / CR Receivable`-for-payment-amount, not -net-settlement). - -### ✅ #3 — Migrations not idempotent (violates fork-migrations contract) -`migrations.py:347, 377` (`ALTER TABLE accounts ADD COLUMN -is_active/is_virtual`) and `migrations.py:441, 472, 510` (`CREATE TABLE -roles/role_permissions/user_roles`) lack idempotency guards.

Per CLAUDE.md, the cross-DB write between -`ext_libra` and core `dbversions` is non-atomic — a failed version-bump -leaves the migration to re-run on boot and crash with `duplicate -column` / `table exists` / UNIQUE violation. Bricks the extension until -manual `dbversions` surgery. - -**Fix:** wrap ALTERs with `_alter_add_column_safe`, switch CREATEs to -`CREATE TABLE IF NOT EXISTS`, gate seed INSERTs with `INSERT ... ON -CONFLICT DO NOTHING`. - -### ✅ #4 — Lightning payment recording has no local idempotency gate -`tasks.py:218-322` relies entirely on `fava.add_entry_idempotent` for -dedup, which itself does a read-then-write race on the Fava ledger. On -lnbits restart with a persisted invoice queue, the same `payment_hash` -can re-fire; the per-user lock is in-process only and doesn't survive -restart. Webhook + poller hitting concurrently both pass the -"not present" check and both insert. - -**Fix:** add a `processed_payments(payment_hash TEXT PRIMARY KEY)` -table; `INSERT OR IGNORE` at the top of `on_invoice_paid`; only -proceed if `rowcount == 1`. - ---- - -## HIGH - -### ✅ #5 — Auth prefix-match in `can_access_user_data` -`auth.py:248-251` uses `caller.user_id[:8] == target.user_id[:8]`. -Eight hex chars = 32 bits; birthday collision at ~65k users. - -**Fix:** require full UUID equality; never resolve by prefix in an -authorisation decision. - -### ✅ #6 — `can_access_account` substring match -`auth.py:178-180` does `f"User-{short}" in account.name` — matches -`Expenses:Misc-User-deadbeef` too. - -**Fix:** split on `:`, require segment equality. - -### ✅ #7 — `ChecksumConflictError` never raised by update/delete -`fava_client.py:1392-1482`: Fava 409/412 propagates as raw -`HTTPStatusError`. The `ChecksumConflictError` type exists but isn't -raised by these methods; callers see stack-trace 500s instead of a -clean retry path. - -**Fix:** `if status in (409, 412): raise ChecksumConflictError(...)`. - -### ✅ #8 — `float()` arithmetic in fiat-rate metadata -`views_api.py:1061-1062, 1263-1264, 1364-1365, 1759-1760` compute -`fiat_rate` / `btc_rate` via `float()`, then persist into Beancount -metadata as the cost basis for that entry. Float drift cascades -through reporting. - -**Fix:** keep `Decimal` end-to-end; only stringify at JSON-serialise -time. - -### ✅ #9 — Background loop swallows `raise` in `on_invoice_paid` -`tasks.py:320-322` does `logger.error(...); raise`. -`wait_for_paid_invoices` at `tasks.py:178-180` has no surrounding -try/except, so one unhandled exception kills the listener for the -rest of the process lifetime — no further Lightning payments get -recorded, no alarm. - -**Fix:** wrap the iteration body in -`try/except Exception: logger.exception(...)`; never `raise` from -`on_invoice_paid`. - -### ✅ #10 — `record-payment` dedup is non-atomic AND exception-swallowing -`views_api.py:1841-1924` (per subagent report — needs verification) -catches all exceptions in the dedup window with a 5-second timeout -and treats Fava errors as "not duplicate", producing double-entries -on transient Fava blips. - -**Fix:** fail closed on transport error; narrow the exception type -catch to `httpx.HTTPError` only. - -### ✅ #11 — `validate_journal_entry` is stale -`core/validation.py:21-93` validates the pre-string-amount model — -sums one bag of integers, doesn't balance per currency. Doesn't match -production data shape post-Fava migration. - -**Fix:** rewrite to parse `"X CCY"` strings and balance per currency, -or delete if Beancount-side validation is now considered sufficient. - ---- - -## MEDIUM - -### ✅ #12 — `m001_initial` seed `INSERT` into `accounts` non-idempotent -`migrations.py:319-330` — same shape as #3. - -### ✅ #13 — `format_posting_at_average_cost` emits `{}` when `cost_currency=None` -`beancount_format.py:256` — ` SATS {}` isn't valid Beancount -syntax; drop the braces when cost is unset. - -### ✅ #14 — Per-call `httpx.AsyncClient` instantiation in fava_client -~30 sites build a new `httpx.AsyncClient` per call.
