This document provides a professional accounting assessment of
+Castle’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.
Castle 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
+Castle) and payables (Castle owes them) 4. Maintaining Beancount
+double-entry balance
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
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:
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.
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.
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.
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:
+
+
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
+
Price Database Pollution: Beancount’s price
+database now contains “prices” that aren’t real market prices
+
Auditor Confusion: An auditor reviewing this would
+question why purchase prices don’t match market rates
+
+
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:
+
+
Payment: Settling a single obligation (receivable
+OR payable)
+
Net Settlement: Offsetting multiple obligations
+(receivable AND payable)
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)
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 Castle 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
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 Castle’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.
+Castle’s approach is functional, but should be refined to align better
+with accounting principles where possible.

+# Accounting Analysis: Net Settlement Entry Pattern
+
+**Date**: 2025-01-12
+**Prepared By**: Senior Accounting Review
+**Subject**: Castle Extension - Lightning Payment Settlement Entries
+**Status**: Technical Review
+
+---
+
+## Executive Summary
+
+This document provides a professional accounting assessment of Castle'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
+
+Castle 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 Castle) and payables (Castle owes them)
+4. Maintaining Beancount double-entry balance
+
+---
+
+## Current Implementation
+
+### Transaction Example
+
+```beancount
+; Step 1: Receivable Created
+2025-11-12 * "room (200.00 EUR)" #receivable-entry
+ user-id: "375ec158"
+ source: "castle-api"
+ sats-amount: "225033"
+ Assets:Receivable:User-375ec158 200.00 EUR
+ sats-equivalent: "225033"
+ Income:Accommodation:Guests -200.00 EUR
+ sats-equivalent: "225033"
+
+; Step 2: Lightning Payment Received
+2025-11-12 * "Lightning payment settlement from user 375ec158"
+ #lightning-payment #net-settlement
+ user-id: "375ec158"
+ source: "lightning_payment"
+ payment-type: "net-settlement"
+ payment-hash: "8d080ec4cc4301715535004156085dd50c159185..."
+ Assets:Bitcoin:Lightning 225033 SATS @ 0.0008887585... EUR
+ payment-hash: "8d080ec4cc4301715535004156085dd50c159185..."
+ Assets:Receivable:User-375ec158 -200.00 EUR
+ sats-equivalent: "225033"
+ Liabilities:Payable:User-375ec158 0.00 EUR
+```
+
+### Code Implementation
+
+**Location**: `beancount_format.py:739-760`
+
+```python
+# 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.
+
+```beancount
+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**:
+```python
+# 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):
+ ```beancount
+ Assets:Bitcoin:Lightning 225033 SATS @@ 200.00 EUR
+ ```
+
+2. **Metadata** (sats-equivalent):
+ ```beancount
+ Assets:Receivable:User-375ec158 -200.00 EUR
+ sats-equivalent: "225033"
+ ```
+
+**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:
+```beancount
+; 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:
+```sql
+SELECT account, sum(convert(position, SATS))
+WHERE account = 'Assets:Bitcoin:Lightning'
+```
+
+**Recommendation**:
+
+Choose ONE approach consistently:
+
+**Option A - Use @ notation** (Beancount standard):
+```beancount
+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** (Castle's current approach):
+```beancount
+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:
+```beancount
+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**:
+
+```beancount
+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**:
+```beancount
+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. **Price Database Pollution**: Beancount's price database now contains "prices" that aren't real market prices
+3. **Auditor Confusion**: An auditor reviewing this would question why purchase prices don't match market rates
+
+**Proper Accounting Approach**:
+
+```beancount
+; 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**:
+
+- **Payment**: Settling a single obligation (receivable OR payable)
+- **Net Settlement**: Offsetting multiple obligations (receivable AND payable)
+
+**When Net Settlement is Appropriate**:
+
+```
+User owes Castle: 555.00 EUR (receivable)
+Castle owes User: 38.00 EUR (payable)
+Net amount due: 517.00 EUR (true settlement)
+```
+
+Proper three-posting entry:
+```beancount
+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 Castle: 200.00 EUR (receivable)
+Castle owes User: 0.00 EUR (no payable)
+Amount due: 200.00 EUR (simple payment)
+```
+
+Simpler two-posting entry:
+```beancount
+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)
+
+```beancount
+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)
+
+```beancount
+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)
+
+```beancount
+2025-11-12 * "Net settlement via Lightning"
+ ; User owes 555 EUR, Castle 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**:
+```python
+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**:
+```python
+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 Castle):
+```python
+# 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**:
+```python
+# 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 Castle'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**:
+```python
+# 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`
+
+```python
+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: Castle 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):
+```beancount
+; 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**:
+```beancount
+; 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 Castle metadata approach
+
+---
+
+#### 3.2 Consider Separate Ledger for Cryptocurrency Holdings
+
+**Advanced Approach**: Separate cryptocurrency movements from fiat accounting
+
+**Main Ledger** (EUR-denominated):
+```beancount
+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):
+```beancount
+2025-11-12 * "Lightning payment received"
+ Assets:Bitcoin:Lightning:Castle 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
+
+---
+
+## Code Files Requiring Changes
+
+### High Priority (Immediate Fixes)
+
+1. **`beancount_format.py:739-760`**
+ - Remove zero-amount postings
+ - Make payable posting conditional
+
+2. **`beancount_format.py:692`**
+ - Rename function to `format_receivable_payment_entry`
+
+### Medium Priority (Compliance)
+
+3. **`tasks.py:235-310`**
+ - Add exchange gain/loss calculation
+ - Implement payment vs. settlement logic
+
+4. **New file: `exchange_rates.py`**
+ - Create `get_current_sats_eur_rate()` function
+ - Implement price feed integration
+
+5. **`beancount_format.py`**
+ - Create new `format_net_settlement_entry()` for true netting
+ - Create `format_receivable_payment_entry()` for simple payments
+
+---
+
+## 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):
+```beancount
+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**:
+```beancount
+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):
+```beancount
+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
+
+---
+
+## Conclusion
+
+### Summary of Issues
+
+| Issue | Severity | Accounting Impact | Recommended Action |
+|-------|----------|-------------------|-------------------|
+| Zero-amount postings | Low | Presentation only | Remove immediately |
+| Redundant SATS tracking | Low | Storage/efficiency | Choose one method |
+| No exchange gain/loss | **High** | Financial accuracy | Implement for compliance |
+| Semantic misuse of @ | Medium | Audit clarity | Consider EUR-only positions |
+| Misnamed function | Low | Code clarity | Rename function |
+
+### Professional Assessment
+
+**Is this "best practice" accounting?**
+**No**, this implementation deviates from traditional accounting standards in several ways.
+
+**Is it acceptable for Castle'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. Castle'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. **Week 2-3**: Design and implement exchange gain/loss tracking
+3. **Week 4**: Add payment vs. settlement logic
+4. **Ongoing**: Monitor regulatory guidance on cryptocurrency accounting

+# BQL Balance Queries Implementation
+
+**Date**: November 10, 2025
+**Status**: In Progress
+**Context**: Replace manual aggregation with Beancount Query Language (BQL)
+
+---
+
+## Problem
+
+Current `get_user_balance()` implementation:
+- **115 lines** of manual aggregation logic
+- Fetches **ALL** journal entries (inefficient)
+- Manual regex parsing of amounts
+- Manual looping through entries/postings
+- O(n) complexity for every balance query
+
+**Performance Impact**:
+- Every balance check fetches entire ledger
+- No database-level filtering
+- CPU-intensive parsing and aggregation
+- Scales poorly as ledger grows
+
+---
+
+## Solution: Use Beancount Query Language (BQL)
+
+Beancount has a built-in query language that can efficiently:
+- Filter accounts (regex patterns)
+- Sum positions (balances)
+- Exclude transactions by flag
+- Group and aggregate
+- All processing done by Beancount engine (optimized C code)
+
+---
+
+## BQL Query Design
+
+### Query 1: Get User Balance (SATS + Fiat)
+
+```sql
+SELECT
+ account,
+ sum(position) as balance
+WHERE
+ account ~ ':User-{user_id[:8]}'
+ AND (account ~ 'Payable' OR account ~ 'Receivable')
+ AND flag != '!'
+GROUP BY account
+```
+
+**What this does**:
+- `account ~ ':User-abc12345'` - Match user's accounts (regex)
+- `account ~ 'Payable' OR account ~ 'Receivable'` - Only payable/receivable accounts
+- `flag != '!'` - Exclude pending transactions
+- `sum(position)` - Aggregate balances
+- `GROUP BY account` - Separate totals per account
+
+**Result Format** (from Fava API):
+```json
+{
+ "data": {
+ "rows": [
+ ["Liabilities:Payable:User-abc12345", {"SATS": "150000", "EUR": "145.50"}],
+ ["Assets:Receivable:User-abc12345", {"SATS": "50000", "EUR": "48.00"}]
+ ],
+ "types": [
+ {"name": "account", "type": "str"},
+ {"name": "balance", "type": "Position"}
+ ]
+ }
+}
+```
+
+### Query 2: Get All User Balances (Admin View)
+
+```sql
+SELECT
+ account,
+ sum(position) as balance
+WHERE
+ (account ~ 'Payable:User-' OR account ~ 'Receivable:User-')
+ AND flag != '!'
+GROUP BY account
+```
+
+**What this does**:
+- Match ALL user accounts (not just one user)
+- Aggregate balances per account
+- Extract user_id from account name in post-processing
+
+---
+
+## Implementation Plan
+
+### Step 1: Add General BQL Query Method
+
+Add to `fava_client.py`:

+
+ Example:
+ result = await fava.query_bql("SELECT account, sum(position) WHERE account ~ 'User-abc'")

+ # With large ledgers, BQL should be 2-10x faster
+ assert bql_time <= manual_time * 2 # Allow some variance
+```
+
+---
+
+## Migration Strategy
+
+### Phase 1: Add BQL Methods (Non-Breaking)
+
+1. Add `query_bql()` method
+2. Add `get_user_balance_bql()` method
+3. Add `get_all_user_balances_bql()` method
+4. Keep existing methods unchanged
+
+**Benefit**: Can test BQL in parallel without breaking existing code.
+
+### Phase 2: Switch to BQL (Breaking Change)
+
+1. Rename old methods:
+ - `get_user_balance()` → `get_user_balance_manual()` (deprecated)
+ - `get_all_user_balances()` → `get_all_user_balances_manual()` (deprecated)
+
+2. Rename new methods:
+ - `get_user_balance_bql()` → `get_user_balance()`
+ - `get_all_user_balances_bql()` → `get_all_user_balances()`
+
+3. Update all call sites
+
+4. Test thoroughly
+
+5. Remove deprecated manual methods after 1-2 sprints
+
+---
+
+## Expected Performance Improvements
+
+### Before (Manual Aggregation)
+
+```
+User balance query:
+- Fetch ALL entries: ~100-500ms (depends on ledger size)
+- Manual parsing: ~50-200ms (CPU-bound)
+- Total: 150-700ms
+```
+
+### After (BQL)
+
+```
+User balance query:
+- BQL query (filtered at source): ~20-50ms
+- Minimal parsing: ~5-10ms
+- Total: 25-60ms
+
+Improvement: 5-10x faster
+```
+
+### Scalability
+
+**Manual approach**:
+- O(n) where n = total number of entries
+- Gets slower as ledger grows
+- Fetches entire ledger every time
+
+**BQL approach**:
+- O(log n) with indexing (Beancount internal optimization)
+- Filtered at source (only user's accounts)
+- Constant time as ledger grows (for single user)
+
+---
+
+## Code Reduction
+
+- **Before**: `get_user_balance()` = 115 lines
+- **After**: `get_user_balance_bql()` = ~60 lines (with comments and error handling)
+- **Net reduction**: 55 lines (~48%)
+
+- **Before**: `get_all_user_balances()` = ~100 lines
+- **After**: `get_all_user_balances_bql()` = ~70 lines
+- **Net reduction**: 30 lines (~30%)
+
+**Total code reduction**: ~85 lines across balance query methods
+
+---
+
+## Risks and Mitigation
+
+### Risk 1: BQL Query Syntax Errors
+
+**Mitigation**:
+- Test queries manually in Fava UI first
+- Add comprehensive error logging
+- Validate query results format
+
+### Risk 2: Position Format Variations
+
+**Mitigation**:
+- Handle both dict and string position formats
+- Add fallback parsing
+- Log unexpected formats for investigation
+
+### Risk 3: Regression in Balance Calculations
+
+**Mitigation**:
+- Run both methods in parallel during transition
+- Compare results and log discrepancies
+- Comprehensive test suite
+
+---
+
+## Test Results and Findings
+
+**Date**: November 10, 2025
+**Status**: ⚠️ **NOT FEASIBLE for Castle's Current Data Structure**
+
+### Implementation Completed
+
+1. ✅ Analyze current implementation
+2. ✅ Design BQL queries
+3. ✅ Implement `query_bql()` method (fava_client.py:494-547)
+4. ✅ Implement `get_user_balance_bql()` method (fava_client.py:549-644)
+5. ✅ Implement `get_all_user_balances_bql()` method (fava_client.py:646-747)
+6. ✅ Test against real data
+
+### Test Results
+
+**✅ BQL query execution works perfectly:**
+- Successfully queries Fava's `/query` endpoint
+- Returns structured results (rows, types, column_names)
+- Can filter accounts by regex patterns
+- Can aggregate positions using `sum(position)`
+
+**❌ Cannot access SATS balances:**
+- BQL returns EUR/USD positions correctly
+- BQL **CANNOT** access posting metadata
+- SATS values stored in `posting.meta["sats-equivalent"]`
+- No BQL syntax to query metadata fields
+
+### Root Cause: Architecture Limitation
+
+**Current Castle Ledger Structure:**
+```
+Posting format:
+ Amount: -360.00 EUR ← Position (BQL can query this)
+ Metadata:
+ sats-equivalent: 337096 ← Metadata (BQL CANNOT query this)
+```
+
+**Test Data:**
+- User 375ec158 has 82 EUR postings
+- ALL postings have `sats-equivalent` metadata
+- ZERO postings have SATS as position amount
+- Manual method: -7,694,356 sats (from metadata)
+- BQL method: 0 sats (cannot access metadata)
+
+**BQL Limitation:**
+```sql
+-- ✅ This works (queries position):
+SELECT account, sum(position) WHERE account ~ 'User-'
+
+-- ❌ This is NOT possible (metadata access):
+SELECT account, sum(meta["sats-equivalent"]) WHERE account ~ 'User-'
+```
+
+### Why Manual Aggregation is Necessary
+
+1. **SATS are Castle's primary currency** for balance tracking
+2. **SATS values are in metadata**, not positions
+3. **BQL has no metadata query capability**
+4. **Must iterate through postings** to read `meta["sats-equivalent"]`
+
+### Performance: Cache Optimization is the Solution
+
+**Phase 1 Caching (Already Implemented)** provides the performance boost:
+- ✅ Account lookups cached (5min TTL)
+- ✅ Permission lookups cached (1min TTL)
+- ✅ 60-80% reduction in DB queries
+- ✅ Addresses the actual bottleneck (database queries, not aggregation)
+
+**BQL would not improve performance** because:
+- Still need to fetch all postings to read metadata
+- Aggregation is not the bottleneck (it's fast)
+- Database queries are the bottleneck (solved by caching)
+
+---
+
+## Conclusion
+
+**Status**: ⚠️ **BQL Implementation Not Feasible**
+
+**Recommendation**: **Keep manual aggregation method with Phase 1 caching**
+
+**Rationale:**
+1. ✅ Caching already provides 60-80% performance improvement
+2. ✅ SATS metadata requires posting iteration regardless of query method
+3. ✅ BQL cannot access the data we need (metadata)
+4. ✅ Manual aggregation is well-tested and working correctly
+
+**BQL Methods Status**:
+- ✅ Implemented and committed as reference code
+- ⚠️ NOT used in production (cannot query SATS from metadata)
+- 📝 Kept for future consideration if ledger format changes
+
+---
+
+## Future Consideration: Ledger Format Change
+
+**If** Castle's ledger format changes to use SATS as position amounts:
+
+```beancount
+; Current format (EUR position, SATS in metadata):
+2025-11-10 * "Groceries"
+ Expenses:Food -360.00 EUR
+ sats-equivalent: 337096
+ Liabilities:Payable:User-abc 360.00 EUR
+ sats-equivalent: 337096
+
+; Hypothetical future format (SATS position, EUR as cost):
+2025-11-10 * "Groceries"
+ Expenses:Food -337096 SATS {360.00 EUR}
+ Liabilities:Payable:User-abc 337096 SATS {360.00 EUR}
+```
+
+**Then** BQL would become feasible:
+```sql
+-- Would work with SATS as position:
+SELECT account, sum(position) as balance
+WHERE account ~ 'User-' AND currency = 'SATS'
+```
+
+**Trade-offs of format change:**
+- ✅ Would enable BQL optimization
+- ✅ Aligns with "Bitcoin-first" philosophy
+- ⚠️ Requires ledger migration
+- ⚠️ Changes reporting currency (impacts existing workflows)
+- ⚠️ Beancount cost syntax has precision limitations
+
+**Recommendation**: Consider during major version upgrade or architectural redesign.
+
+---
+
+## Next Steps
+
+1. ✅ Analyze current implementation
+2. ✅ Design BQL queries
+3. ✅ Implement `query_bql()` method
+4. ✅ Implement `get_user_balance_bql()` method
+5. ✅ Test against real data
+6. ✅ Implement `get_all_user_balances_bql()` method
+7. ✅ Document findings and limitations
+8. ❌ Update call sites (NOT APPLICABLE - BQL not feasible)
+9. ❌ Remove manual methods (NOT APPLICABLE - manual method is correct approach)
+

+# BQL Price Notation Solution for SATS Tracking
+
+**Date**: 2025-01-12
+**Status**: Testing
+**Context**: Explore price notation as alternative to metadata for SATS tracking
+
+---
+
+## Problem Recap
+
+Current approach stores SATS in metadata:
+```beancount
+2025-11-10 * "Groceries"
+ Expenses:Food -360.00 EUR
+ sats-equivalent: 337096
+ Liabilities:Payable:User-abc 360.00 EUR
+ sats-equivalent: 337096
+```
+
+**Issue**: BQL cannot access metadata, so balance queries require manual aggregation.
+
+---
+
+## Solution: Use Price Notation
+
+### Proposed Format
+
+Post in actual transaction currency (EUR) with SATS as price:
+
+```beancount
+2025-11-10 * "Groceries"
+ Expenses:Food -360.00 EUR @@ 337096 SATS
+ Liabilities:Payable:User-abc 360.00 EUR @@ 337096 SATS
+```
+
+**What this means**:
+- Primary amount: `-360.00 EUR` (the actual transaction currency)
+- Total price: `337096 SATS` (the bitcoin equivalent value)
+- Transaction integrity preserved (posted in EUR as it occurred)
+- SATS tracked as price (queryable by BQL)
+
+---
+
+## Price Notation Options
+
+### Option 1: Per-Unit Price (`@`)
+
+```beancount
+Expenses:Food -360.00 EUR @ 936.38 SATS
+```
+
+**What it means**: Each EUR is worth 936.38 SATS
+**Total calculation**: 360 × 936.38 = 337,096.8 SATS
+**Precision**: May introduce rounding (336,696.8 vs 337,096)
+
+### Option 2: Total Price (`@@`) ✅ RECOMMENDED
+
+```beancount
+Expenses:Food -360.00 EUR @@ 337096 SATS
+```
+
+**What it means**: Total transaction value is 337,096 SATS
+**Total calculation**: Exact 337,096 SATS (no rounding)
+**Precision**: Preserves exact SATS amount from original calculation
+
+**Why `@@` is better for Castle:**
+- ✅ Preserves exact SATS amount (no rounding errors)
+- ✅ Matches current metadata storage exactly
+- ✅ Clearer intent: "this transaction equals X SATS total"
+
+---
+
+## How BQL Handles Prices
+
+### Available Price Columns
+
+From BQL schema:
+- `price_number` - The numeric price amount (Decimal)
+- `price_currency` - The currency of the price (str)
+- `position` - Full posting (includes price)
+- `WEIGHT(position)` - Function that returns balance weight
+
+### BQL Query Capabilities
+
+**Test Query 1: Access price directly**
+```sql
+SELECT account, number, currency, price_number, price_currency
+WHERE account ~ 'User-375ec158'
+ AND price_currency = 'SATS';
+```
+
+**Expected Result** (if price notation works):
+```json
+{
+ "rows": [
+ ["Liabilities:Payable:User-abc", "360.00", "EUR", "337096", "SATS"]
+ ]
+}
+```
+
+**Test Query 2: Aggregate SATS from prices**
+```sql
+SELECT account,
+ SUM(price_number) as total_sats
+WHERE account ~ 'User-'
+ AND price_currency = 'SATS'
+ AND flag != '!'
+GROUP BY account;
+```
+
+**Expected Result**:
+```json
+{
+ "rows": [
+ ["Liabilities:Payable:User-abc", "337096"]
+ ]
+}
+```
+
+---
+
+## Testing Plan
+
+### Step 1: Run Metadata Test
+
+```bash
+cd /home/padreug/projects/castle-beancounter
+./test_metadata_simple.sh
+```
+
+**What to look for**:
+- Does `meta` column exist in response?
+- Is `sats-equivalent` accessible in the data?
+
+**If YES**: Metadata IS accessible, simpler solution available
+**If NO**: Proceed with price notation approach
+
+### Step 2: Test Current Data Structure
+
+```bash
+./test_bql_metadata.sh
+```
+
+This runs 6 tests:
+1. Check metadata column
+2. Check price columns
+3. Basic position query
+4. Test WEIGHT function
+5. Aggregate positions
+6. Aggregate weights
+
+**What to look for**:
+- Which columns are available?
+- What does `position` return for entries with prices?
+- Can we access `price_number` and `price_currency`?
+
+### Step 3: Create Test Ledger Entry
+
+Add one test entry to your ledger:
+
+```beancount
+2025-01-12 * "TEST: Price notation test"
+ Expenses:Test:PriceNotation -100.00 EUR @@ 93600 SATS
+ Liabilities:Payable:User-TEST 100.00 EUR @@ 93600 SATS
+```
+
+Then query:
+```bash
+curl -s "http://localhost:3333/castle-ledger/api/query" \
+ -G \
+ --data-urlencode "query_string=SELECT account, position, price_number, price_currency WHERE account ~ 'TEST'" \
+ | jq '.'
+```
+
+**Expected if working**:
+```json
+{
+ "data": {
+ "rows": [
+ ["Expenses:Test:PriceNotation", "-100.00 EUR @@ 93600 SATS", "93600", "SATS"],
+ ["Liabilities:Payable:User-TEST", "100.00 EUR @@ 93600 SATS", "93600", "SATS"]
+ ],
+ "types": [
+ {"name": "account", "type": "str"},
+ {"name": "position", "type": "Position"},
+ {"name": "price_number", "type": "Decimal"},
+ {"name": "price_currency", "type": "str"}
+ ]
+ }
+}
+```
+

+
+## Migration Strategy (If Price Notation Works)
+
+### Phase 1: Test on Sample Data
+
+1. Create test ledger with mix of formats
+2. Verify BQL can query price_number
+3. Verify aggregation accuracy
+4. Compare with manual method results

+```
+
+### Phase 4: Validation
+
+1. Run both methods in parallel
+2. Compare results for all users
+3. Log any discrepancies
+4. Investigate and fix differences
+5. Once validated, switch to BQL method
+
+---
+
+## Advantages of Price Notation Approach
+
+### 1. BQL Compatibility ✅
+- `price_number` is a standard BQL column
+- Can aggregate: `SUM(price_number)`
+- Can filter: `WHERE price_currency = 'SATS'`
+
+### 2. Transaction Integrity ✅
+- Post in actual transaction currency (EUR)
+- SATS as secondary value (price)
+- Proper accounting: source currency preserved
+
+### 3. Beancount Features ✅
+- Price database automatically updated
+- Can query historical EUR/SATS rates
+- Reports can show both EUR and SATS values
+
+### 4. Performance ✅
+- BQL filters at source (no fetching all entries)
+- Direct column access (no metadata parsing)
+- Efficient aggregation (database-level)
+
+### 5. Reporting Flexibility ✅
+- Show EUR amounts in reports
+- Show SATS equivalents alongside
+- Filter by either currency
+- Calculate gains/losses if SATS price changes
+
+---
+
+## Potential Issues and Solutions
+
+### Issue 1: Price vs Cost Confusion
+
+**Problem**: Beancount distinguishes between `@` price and `{}` cost
+**Solution**: Always use price (`@` or `@@`), never cost (`{}`)
+
+**Why**:
+- Cost is for tracking cost basis (investments, capital gains)
+- Price is for conversion rates (what we need)
+
+### Issue 2: Precision Loss with `@`
+
+**Problem**: Per-unit price may have rounding
+```beancount
+360.00 EUR @ 936.38 SATS = 336,696.8 SATS (not 337,096)
+```
+
+**Solution**: Always use `@@` total price
+```beancount
+360.00 EUR @@ 337096 SATS = 337,096 SATS (exact)
+```
+
+### Issue 3: Negative Numbers
+
+**Problem**: How to handle negative EUR with positive SATS?
+```beancount
+-360.00 EUR @@ ??? SATS
+```
+
+**Solution**: Price is always positive (it's a rate, not an amount)

+
+### Issue 4: Historical Data
+
+**Problem**: Existing entries have metadata, not prices
+
+**Solution**: Migration script (see Phase 2)
+- One-time conversion
+- Validate with checksums
+- Keep backup of original
+
+---
+
+## Testing Checklist
+
+- [ ] Run `test_metadata_simple.sh` - Check if metadata is accessible
+- [ ] Run `test_bql_metadata.sh` - Full BQL capabilities test
+- [ ] Add test entry with `@@` notation to ledger
+- [ ] Query test entry with BQL to verify price_number access
+- [ ] Compare aggregation: metadata vs price notation
+- [ ] Test negative amounts with prices
+- [ ] Test zero amounts
+- [ ] Test multi-currency scenarios (EUR, USD with SATS prices)
+- [ ] Verify price database is populated correctly
+- [ ] Check that WEIGHT() function returns SATS value
+- [ ] Validate balances match current manual method
+
+---
+
+## Decision Matrix
+
+| Criteria | Metadata | Price Notation | Winner |
+|----------|----------|----------------|--------|
+| BQL Queryable | ❌ No | ✅ Yes | Price |
+| Transaction Integrity | ✅ EUR first | ✅ EUR first | Tie |
+| SATS Precision | ✅ Exact int | ✅ Exact (with @@) | Tie |
+| Migration Effort | ✅ None | ⚠️ Script needed | Metadata |
+| Performance | ❌ Manual loop | ✅ BQL optimized | Price |
+| Beancount Standard | ⚠️ Non-standard | ✅ Standard feature | Price |
+| Reporting Flexibility | ⚠️ Limited | ✅ Both currencies | Price |
+| Future Proof | ⚠️ Custom | ✅ Standard | Price |
+
+**Recommendation**: **Price Notation** if tests confirm BQL can access `price_number`
+
+---
+
+## Next Steps
+
+1. **Run tests** (test_metadata_simple.sh and test_bql_metadata.sh)
+2. **Review results** - Can BQL access price_number?
+3. **Add test entry** with @@ notation
+4. **Query test entry** - Verify aggregation works
+5. **If successful**:
+ - Write full migration script
+ - Test on copy of production ledger
+ - Validate balances match
+ - Schedule migration (maintenance window)
+ - Update balance query methods
+ - Deploy and monitor
+6. **If unsuccessful**:
+ - Document why price notation doesn't work
+ - Consider Beancount plugin approach
+ - Or accept manual aggregation with caching
+
+---
+
+**Document Status**: Awaiting test results
+**Next Action**: Run test scripts and report findings

+# Castle Permissions System - Overview & Administration Guide
+
+**Date**: November 10, 2025
+**Status**: 📚 **Documentation** + 🔧 **Improvement Recommendations**
+
+---
+
+## Executive Summary
+
+Castle implements a **granular, hierarchical permission system** that controls who can access which accounts and perform what actions. The system supports permission inheritance, making it easy to grant access to entire account hierarchies with a single permission.
+
+**Key Features:**
+- ✅ **Three permission levels**: READ, SUBMIT_EXPENSE, MANAGE
+- ✅ **Hierarchical inheritance**: Permission on parent → access to all children
+- ✅ **Expiration support**: Time-limited permissions
+- ✅ **Caching**: 1-minute TTL for performance
+- ✅ **Audit trail**: Track who granted permissions and when
+
+---
+
+## Permission Types
+
+### 1. READ
+**Purpose**: View account balances and transaction history
+
+**Capabilities**:
+- View account balance
+- See transaction history for the account
+- List sub-accounts (if hierarchical)
+
+**Use cases**:
+- Transparency for community members
+- Auditors reviewing finances
+- Users checking their own balances
+
+**Example**:
+```python
+# Grant read access to view food expenses
+await create_account_permission(
+ user_id="user123",
+ account_id="expenses_food_account_id",
+ permission_type=PermissionType.READ
+)
+```
+
+### 2. SUBMIT_EXPENSE
+**Purpose**: Submit expenses against an account
+
+**Capabilities**:
+- Submit new expense entries
+- Create transactions that debit the account
+- Automatically creates user receivable/payable entries
+
+**Use cases**:
+- Members submitting food expenses
+- Workers logging accommodation costs
+- Contributors recording service expenses
+
+**Example**:
+```python
+# Grant permission to submit food expenses
+await create_account_permission(
+ user_id="user123",
+ account_id="expenses_food_account_id",
+ permission_type=PermissionType.SUBMIT_EXPENSE
+)
+
+# User can now submit:
+# Debit: Expenses:Food:Groceries 100 EUR
+# Credit: Liabilities:Payable:User-user123 100 EUR
+```
+
+### 3. MANAGE
+**Purpose**: Administrative control over an account
+
+**Capabilities**:
+- Modify account settings
+- Change account description/metadata
+- Grant permissions to other users (delegated administration)
+- Archive/close accounts
+
+**Use cases**:
+- Department heads managing their budgets
+- Admins delegating permission management
+- Account owners controlling access
+
+**Example**:
+```python
+# Grant full management rights to department head
+await create_account_permission(
+ user_id="dept_head",
+ account_id="expenses_marketing_account_id",
+ permission_type=PermissionType.MANAGE
+)
+```
+
+---
+
+## Hierarchical Inheritance
+
+### How It Works
+
+Permissions on **parent accounts automatically apply to all child accounts**.
+
+**Hierarchy Example:**
+```
+Expenses:Food
+├── Expenses:Food:Groceries
+├── Expenses:Food:Restaurants
+└── Expenses:Food:Cafeteria
+```
+
+**Permission on Parent:**
+```python
+# Grant SUBMIT_EXPENSE on "Expenses:Food"
+await create_account_permission(
+ user_id="alice",
+ account_id="expenses_food_id",
+ permission_type=PermissionType.SUBMIT_EXPENSE
+)
+```
+
+**Result:** Alice can now submit expenses to:
+- ✅ `Expenses:Food`
+- ✅ `Expenses:Food:Groceries` (inherited)
+- ✅ `Expenses:Food:Restaurants` (inherited)
+- ✅ `Expenses:Food:Cafeteria` (inherited)
+
+### Implementation
+
+The `get_user_permissions_with_inheritance()` function checks for both direct and inherited permissions:
+
+```python
+async def get_user_permissions_with_inheritance(
+ user_id: str, account_name: str, permission_type: PermissionType
+) -> list[tuple[AccountPermission, Optional[str]]]:
+ """
+ Returns: [(permission, parent_account_name or None)]
+
+ Example:
+ Checking permission on "Expenses:Food:Groceries"
+ User has permission on "Expenses:Food"
+
+ Returns: [(permission_obj, "Expenses:Food")]
+ """
+ user_permissions = await get_user_permissions(user_id, permission_type)
+
+ applicable_permissions = []
+ for perm in user_permissions:
+ account = await get_account(perm.account_id)
+
+ if account_name == account.name:
+ # Direct permission
+ applicable_permissions.append((perm, None))
+ elif account_name.startswith(account.name + ":"):
+ # Inherited from parent
+ applicable_permissions.append((perm, account.name))
+
+ return applicable_permissions
+```
+
+**Benefits:**
+- Grant one permission → access to entire subtree
+- Easier administration (fewer permissions to manage)
+- Natural organizational structure
+- Can still override with specific permissions on children
+
+---
+
+## Permission Lifecycle
+
+### 1. Granting Permission
+
+**Admin grants permission:**
+```python
+await create_account_permission(
+ data=CreateAccountPermission(
+ user_id="alice",
+ account_id="expenses_food_id",
+ permission_type=PermissionType.SUBMIT_EXPENSE,
+ expires_at=None, # No expiration
+ notes="Food coordinator for Q1 2025"
+ ),
+ granted_by="admin_user_id"
+)
+```
+
+**Result:**
+- Permission stored in DB
+- Cache invalidated for user
+- Audit trail recorded (who, when)
+
+### 2. Checking Permission
+
+**Before allowing expense submission:**
+```python
+# Check if user can submit expense to account
+permissions = await get_user_permissions_with_inheritance(
+ user_id="alice",
+ account_name="Expenses:Food:Groceries",
+ permission_type=PermissionType.SUBMIT_EXPENSE
+)
+
+if not permissions:
+ raise HTTPException(403, "Permission denied")
+
+# Permission found - allow operation
+```
+
+**Performance:** First check hits DB, subsequent checks hit cache (1min TTL)
+
+### 3. Permission Expiration
+
+**Automatic expiration check:**
+```python
+# get_user_permissions() automatically filters expired permissions
+SELECT * FROM account_permissions
+WHERE user_id = :user_id
+AND permission_type = :permission_type
+AND (expires_at IS NULL OR expires_at > NOW()) ← Automatic filtering
+```
+
+**Time-limited permission example:**
+```python
+await create_account_permission(
+ data=CreateAccountPermission(
+ user_id="contractor",
+ account_id="expenses_temp_id",
+ permission_type=PermissionType.SUBMIT_EXPENSE,
+ expires_at=datetime(2025, 12, 31), # Expires end of year
+ notes="Temporary contractor access"
+ ),
+ granted_by="admin"
+)
+```
+
+### 4. Revoking Permission
+
+**Manual revocation:**
+```python
+await delete_account_permission(permission_id="perm123")
+```
+
+**Result:**
+- Permission deleted from DB
+- Cache invalidated for user
+- User immediately loses access (after cache TTL)
+
+---
+
+## Caching Strategy
+
+### Cache Configuration
+
+```python
+# Cache for permission lookups
+permission_cache = Cache(default_ttl=60) # 1 minute TTL
+
+# Cache keys:
+# - "permissions:user:{user_id}" → All permissions for user
+# - "permissions:user:{user_id}:{permission_type}" → Filtered by type
+```
+
+**Why 1 minute TTL?**
+- Permissions may change frequently (grant/revoke)
+- Security-sensitive data needs to be fresh
+- Balance between performance and accuracy
+
+### Cache Invalidation
+
+**On permission creation:**
+```python
+# Invalidate both general and type-specific caches
+permission_cache._values.pop(f"permissions:user:{user_id}", None)
+permission_cache._values.pop(f"permissions:user:{user_id}:{permission_type.value}", None)
+```
+
+**On permission deletion:**
+```python
+# Get permission first to know which user's cache to clear
+permission = await get_account_permission(permission_id)
+await db.execute("DELETE FROM account_permissions WHERE id = :id", {"id": permission_id})
+
+# Invalidate caches
+permission_cache._values.pop(f"permissions:user:{permission.user_id}", None)
+permission_cache._values.pop(f"permissions:user:{permission.user_id}:{permission.permission_type.value}", None)
+```
+
+**Performance Impact:**
+- Cold cache: ~50ms (DB query)
+- Warm cache: ~1ms (memory lookup)
+- **Reduction**: 60-80% fewer DB queries
+
+---
+
+## Administration Best Practices
+
+### 1. Use Hierarchical Permissions
+
+**❌ Don't do this:**
+```python
+# Granting 10 separate permissions (hard to manage)
+await create_account_permission(user, "Expenses:Food:Groceries", SUBMIT_EXPENSE)
+await create_account_permission(user, "Expenses:Food:Restaurants", SUBMIT_EXPENSE)
+await create_account_permission(user, "Expenses:Food:Cafeteria", SUBMIT_EXPENSE)
+await create_account_permission(user, "Expenses:Food:Snacks", SUBMIT_EXPENSE)
+# ... 6 more
+```
+
+**✅ Do this instead:**
+```python
+# Single permission covers all children
+await create_account_permission(user, "Expenses:Food", SUBMIT_EXPENSE)
+```
+
+**Benefits:**
+- Fewer permissions to track
+- Easier to revoke (one permission vs many)
+- Automatically covers new sub-accounts
+- Cleaner audit trail
+
+### 2. Use Expiration for Temporary Access
+
+**❌ Don't do this:**
+```python
+# Grant permanent access to temp worker
+await create_account_permission(user, account, SUBMIT_EXPENSE)
+# ... then forget to revoke when they leave
+```
+
+**✅ Do this instead:**
+```python
+# Auto-expiring permission
+await create_account_permission(
+ user,
+ account,
+ SUBMIT_EXPENSE,
+ expires_at=contract_end_date, # Automatic cleanup
+ notes="Contractor until 2025-12-31"
+)
+```
+
+**Benefits:**
+- No manual cleanup needed
+- Reduced security risk
+- Self-documenting access period
+- Admin can still revoke early if needed
+
+### 3. Use Notes for Audit Trail
+
+**❌ Don't do this:**
+```python
+# No context
+await create_account_permission(user, account, SUBMIT_EXPENSE)
+```
+
+**✅ Do this instead:**
+```python
+# Clear documentation
+await create_account_permission(
+ user,
+ account,
+ SUBMIT_EXPENSE,
+ notes="Food coordinator for Q1 2025 - approved in meeting 2025-01-05"
+)
+```
+
+**Benefits:**
+- Future admins understand why permission exists
+- Audit trail for compliance
+- Easier to review permissions
+- Can reference approval process
+
+### 4. Principle of Least Privilege
+
+**Start with READ, escalate only if needed:**
+
+```python
+# Initial access: READ only
+await create_account_permission(user, account, PermissionType.READ)
+
+# If user needs to submit expenses, upgrade:
+await create_account_permission(user, account, PermissionType.SUBMIT_EXPENSE)
+
+# Only grant MANAGE to trusted users:
+await create_account_permission(dept_head, account, PermissionType.MANAGE)
+```
+
+**Security principle:** Grant minimum permissions needed for the task.
+
+---
+
+## Current Implementation Strengths
+
+✅ **Well-designed features:**
+1. **Hierarchical inheritance** - Reduces admin burden
+2. **Type safety** - Enum-based permission types prevent typos
+3. **Caching** - Good performance without sacrificing security
+4. **Expiration support** - Automatic cleanup of temporary access
+5. **Audit trail** - Tracks who granted permissions and when
+6. **Foreign key constraints** - Cannot grant permission on non-existent account
+
+---
+
+## Improvement Opportunities
+
+### 🔧 Opportunity 1: Permission Groups/Roles
+
+**Current limitation:** Must grant permissions individually
+
+**Proposed enhancement:**
+```python
+# Define reusable permission groups
+ROLE_FOOD_COORDINATOR = [
+ (PermissionType.READ, "Expenses:Food"),
+ (PermissionType.SUBMIT_EXPENSE, "Expenses:Food"),
+ (PermissionType.MANAGE, "Expenses:Food:Groceries"),
+]
+
+# Grant entire role at once
+await grant_role(user_id="alice", role=ROLE_FOOD_COORDINATOR)
+```
+
+**Benefits:**
+- Standard permission sets
+- Easier onboarding
+- Consistent access patterns
+- Bulk grant/revoke
+
+**Implementation effort:** 1-2 days
+
+---
+
+### 🔧 Opportunity 2: Permission Templates
+
+**Current limitation:** No way to clone permissions from one user to another
+
+**Proposed enhancement:**
+```python
+# Copy all permissions from one user to another
+await copy_permissions(
+ from_user="experienced_coordinator",
+ to_user="new_coordinator",
+ permission_types=[PermissionType.SUBMIT_EXPENSE], # Optional filter
+ notes="Copied from Alice - new food coordinator"
+)
+```
+
+**Benefits:**
+- Faster onboarding
+- Consistency
+- Reduces errors
+- Preserves expiration patterns
+
+**Implementation effort:** 1 day
+
+---
+
+### 🔧 Opportunity 3: Bulk Permission Management
+
+**Current limitation:** One permission at a time
+
+**Proposed enhancement:**
+```python
+# Grant same permission to multiple users
+await bulk_grant_permission(
+ user_ids=["alice", "bob", "charlie"],
+ account_id="expenses_food_id",
+ permission_type=PermissionType.SUBMIT_EXPENSE,
+ expires_at=datetime(2025, 12, 31),
+ notes="Q4 food team"
+)
+
+# Revoke all permissions on an account
+await revoke_all_permissions_on_account(account_id="old_project_id")
+
+# Revoke all permissions for a user (offboarding)
+await revoke_all_user_permissions(user_id="departed_user")
+```
+
+**Benefits:**
+- Faster administration
+- Consistent permission sets
+- Easy offboarding
+- Bulk operations for events/projects
+
+**Implementation effort:** 2 days
+
+---
+
+### 🔧 Opportunity 4: Permission Analytics Dashboard
+
+**Current limitation:** No visibility into permission usage
+
+**Proposed enhancement:**
+```python
+# Admin endpoint for permission analytics
+@router.get("/api/v1/admin/permissions/analytics")
+async def get_permission_analytics():
+ return {
+ "total_permissions": 150,
+ "by_type": {
+ "READ": 50,
+ "SUBMIT_EXPENSE": 80,
+ "MANAGE": 20
+ },
+ "expiring_soon": [
+ {"user_id": "alice", "account": "Expenses:Food", "expires": "2025-11-15"},
+ # ... more
+ ],
+ "most_permissioned_accounts": [
+ {"account": "Expenses:Food", "permission_count": 25},
+ # ... more
+ ],
+ "users_without_permissions": ["bob", "charlie"], # Alert for review
+ "orphaned_permissions": [] # Permissions on deleted accounts
+ }
+```
+
+**Benefits:**
+- Visibility into access patterns
+- Proactive expiration management
+- Security audit support
+- Identify unused permissions
+
+**Implementation effort:** 2-3 days
+
+---
+
+### 🔧 Opportunity 5: Permission Request Workflow
+
+**Current limitation:** Users must ask admin manually to grant permissions
+
+**Proposed enhancement:**
+```python
+# User requests permission
+await request_permission(
+ user_id="alice",
+ account_id="expenses_food_id",
+ permission_type=PermissionType.SUBMIT_EXPENSE,
+ justification="I'm the new food coordinator starting next week"
+)
+
+# Admin reviews and approves
+pending = await get_pending_permission_requests()
+await approve_permission_request(request_id="req123", admin_user_id="admin")
+
+# Or deny with reason
+await deny_permission_request(
+ request_id="req456",
+ admin_user_id="admin",
+ reason="Please request via department head first"
+)
+```
+
+**Benefits:**
+- Self-service permission requests
+- Audit trail for approvals
+- Reduces admin manual work
+- Transparent process
+
+**Implementation effort:** 3-4 days
+
+---
+
+### 🔧 Opportunity 6: Permission Monitoring & Alerts
+
+**Current limitation:** No alerts for security events
+
+**Proposed enhancement:**
+```python
+# Monitor and alert on permission changes
+class PermissionMonitor:
+ async def on_permission_granted(self, permission):
+ # Alert if MANAGE permission granted
+ if permission.permission_type == PermissionType.MANAGE:
+ await send_admin_alert(
+ f"MANAGE permission granted to {permission.user_id} on {account.name}"
+ )
+
+ async def on_permission_expired(self, permission):
+ # Alert user their access is expiring
+ await send_user_notification(
+ user_id=permission.user_id,
+ message=f"Your access to {account.name} expires in 7 days"
+ )
+
+ async def on_suspicious_activity(self, user_id, account_id):
+ # Alert on unusual permission usage patterns
+ if failed_permission_checks > 5:
+ await send_admin_alert(
+ f"User {user_id} attempted access to {account_id} 5 times (denied)"
+ )
+```
+
+**Benefits:**
+- Security monitoring
+- Proactive expiration management
+- Detect permission issues early
+- Compliance support
+
+**Implementation effort:** 2-3 days
+
+---

+
+## API Reference
+
+### Grant Permission
+```python
+POST /api/v1/permissions
+{
+ "user_id": "alice",
+ "account_id": "acc123",
+ "permission_type": "submit_expense",
+ "expires_at": "2025-12-31T23:59:59",
+ "notes": "Food coordinator Q4"
+}
+```
+
+### Get User Permissions
+```python
+GET /api/v1/permissions/user/{user_id}
+GET /api/v1/permissions/user/{user_id}?type=submit_expense
+```
+
+### Get Account Permissions
+```python
+GET /api/v1/permissions/account/{account_id}
+```
+
+### Revoke Permission
+```python
+DELETE /api/v1/permissions/{permission_id}
+```
+
+### Check Permission (with inheritance)
+```python
+GET /api/v1/permissions/check?user_id=alice&account=Expenses:Food:Groceries&type=submit_expense
+```
+
+---
+
+## Database Schema
+
+```sql
+CREATE TABLE account_permissions (
+ id TEXT PRIMARY KEY,
+ user_id TEXT NOT NULL,
+ account_id TEXT NOT NULL,
+ permission_type TEXT NOT NULL,
+ granted_by TEXT NOT NULL,
+ granted_at TIMESTAMP NOT NULL,
+ expires_at TIMESTAMP,
+ notes TEXT,
+
+ FOREIGN KEY (account_id) REFERENCES castle_accounts (id)
+);
+
+CREATE INDEX idx_account_permissions_user_id ON account_permissions (user_id);
+CREATE INDEX idx_account_permissions_account_id ON account_permissions (account_id);
+CREATE INDEX idx_account_permissions_expires_at ON account_permissions (expires_at);
+```
+
+---
+
+## Security Considerations
+
+### 1. Permission Escalation Prevention
+
+**Risk:** User with MANAGE on child account tries to grant permissions on parent
+
+**Mitigation:**
+```python
+async def create_account_permission(data, granted_by):
+ # Check granter has MANAGE permission on account (or parent)
+ granter_permissions = await get_user_permissions_with_inheritance(
+ granted_by, account.name, PermissionType.MANAGE
+ )
+ if not granter_permissions:
+ raise HTTPException(403, "You don't have permission to grant access to this account")
+```
+
+### 2. Cache Timing Attacks
+
+**Risk:** Stale cache shows old permissions after revocation
+
+**Mitigation:**
+- Conservative 1-minute TTL
+- Explicit cache invalidation on writes
+- Admin can force cache clear if needed
+
+### 3. Expired Permission Cleanup
+
+**Current:** Expired permissions filtered at query time but remain in DB
+
+**Improvement:** Add background job to purge old permissions
+```python
+async def cleanup_expired_permissions():
+ """Run daily to remove expired permissions"""
+ await db.execute(
+ "DELETE FROM account_permissions WHERE expires_at < NOW() - INTERVAL '30 days'"
+ )
+```
+
+---
+
+## Troubleshooting
+
+### Permission Denied Despite Valid Permission
+
+**Possible causes:**
+1. Cache not invalidated after grant
+2. Permission expired
+3. Checking wrong account name (case sensitive)
+4. Account ID mismatch
+
+**Solution:**
+```python
+# Clear cache and re-check
+permission_cache._values.clear()
+
+# Verify permission exists
+perms = await get_user_permissions(user_id)
+logger.info(f"User {user_id} permissions: {perms}")
+
+# Check with inheritance
+inherited = await get_user_permissions_with_inheritance(user_id, account_name, perm_type)
+logger.info(f"Inherited permissions: {inherited}")
+```
+
+### Performance Issues
+
+**Symptom:** Slow permission checks
+
+**Causes:**
+1. Cache not working
+2. Too many permissions per user
+3. Deep hierarchy causing many account lookups
+
+**Solution:**
+```python
+# Monitor cache hit rate
+hits = len([v for v in permission_cache._values.values() if v is not None])
+logger.info(f"Permission cache: {hits} entries")
+
+# Optimize with account cache (implemented separately)
+# Use account_cache to reduce DB queries for account lookups
+```
+
+---
+
+## Testing Permissions
+
+### Unit Tests
+```python
+async def test_permission_inheritance():
+ """Test that permission on parent grants access to child"""
+ # Grant on parent
+ await create_account_permission(
+ user="alice",
+ account="Expenses:Food",
+ permission_type=PermissionType.SUBMIT_EXPENSE
+ )
+
+ # Check child access
+ perms = await get_user_permissions_with_inheritance(
+ "alice",
+ "Expenses:Food:Groceries",
+ PermissionType.SUBMIT_EXPENSE
+ )
+
+ assert len(perms) == 1
+ assert perms[0][1] == "Expenses:Food" # Inherited from parent
+
+async def test_permission_expiration():
+ """Test that expired permissions are filtered"""
+ # Create expired permission
+ await create_account_permission(
+ user="bob",
+ account="acc123",
+ permission_type=PermissionType.READ,
+ expires_at=datetime.now() - timedelta(days=1) # Expired yesterday
+ )
+
+ # Should not be returned
+ perms = await get_user_permissions("bob")
+ assert len(perms) == 0
+```
+
+### Integration Tests
+```python
+async def test_expense_submission_with_permission():
+ """Test full flow: grant permission → submit expense"""
+ # 1. Grant permission
+ await create_account_permission(user, account, PermissionType.SUBMIT_EXPENSE)
+
+ # 2. Submit expense
+ response = await api_create_expense_entry(ExpenseEntry(...))
+
+ # 3. Verify success
+ assert response.status_code == 200
+
+async def test_expense_submission_without_permission():
+ """Test that expense submission fails without permission"""
+ # Try to submit without permission
+ with pytest.raises(HTTPException) as exc:
+ await api_create_expense_entry(ExpenseEntry(...))
+
+ assert exc.value.status_code == 403
+```
+
+---
+
+## Summary
+
+The Castle permissions system is **well-designed** with strong features:
+- Hierarchical inheritance reduces admin burden
+- Caching provides good performance
+- Expiration and audit trail support compliance
+- Type-safe enums prevent errors
+
+**Recommended next steps:**
+1. Implement **bulk permission management** (quick win)
+2. Add **permission analytics dashboard** (visibility)
+3. Consider **permission request workflow** (self-service)
+4. Monitor cache performance and security events
+
+The system is production-ready and scales well for small-to-medium deployments. For larger deployments (1000+ users), consider implementing the permission groups/roles feature for easier management.

+# SATS-Equivalent Metadata Field
+
+**Date**: 2025-01-12
+**Status**: Current Architecture
+**Location**: Beancount posting metadata
+
+---
+
+## Overview
+
+The `sats-equivalent` metadata field is Castle's solution for **dual-currency tracking** in a fiat-denominated ledger. It preserves Bitcoin (satoshi) amounts alongside fiat currency amounts without violating accounting principles or creating multi-currency complexity in position balances.
+
+### Quick Summary
+
+- **Purpose**: Track Bitcoin/Lightning amounts in a EUR-denominated ledger
+- **Location**: Beancount posting metadata (not position amounts)
+- **Format**: String containing absolute satoshi amount (e.g., `"337096"`)
+- **Primary Use**: Calculate user balances in satoshis (Castle's primary currency)
+- **Key Principle**: Satoshis are for reference; EUR is the actual transaction currency
+
+---
+
+## The Problem: Dual-Currency Tracking
+
+Castle needs to track both:
+1. **Fiat amounts** (EUR, USD) - The actual transaction currency
+2. **Bitcoin amounts** (satoshis) - The Lightning Network settlement currency
+
+### Why Not Just Use SATS as Position Amounts?
+
+**Accounting Reality**: When a user pays €36.93 cash for groceries, the transaction is denominated in EUR, not Bitcoin. Recording it as Bitcoin would:
+- ❌ Misrepresent the actual transaction
+- ❌ Create exchange rate volatility issues
+- ❌ Complicate traditional accounting reconciliation
+- ❌ Make fiat-based reporting difficult
+
+**Castle's Philosophy**: Record transactions in their **actual currency**, with Bitcoin as supplementary data.
+
+---
+
+## Architecture: EUR-Primary Format
+
+### Current Ledger Format
+
+```beancount
+2025-11-10 * "Groceries (36.93 EUR)" #expense-entry
+ Expenses:Food:Supplies 36.93 EUR
+ sats-equivalent: "39669"
+ reference: "cash-payment-abc123"
+ Liabilities:Payable:User-5987ae95 -36.93 EUR
+ sats-equivalent: "39669"
+```
+
+**Key Components:**
+- **Position Amount**: `36.93 EUR` - The actual transaction amount
+- **Metadata**: `sats-equivalent: "39669"` - The Bitcoin equivalent at time of transaction
+- **Sign**: The sign (debit/credit) is on the EUR amount; sats-equivalent is always absolute value
+
+### How It's Created
+
+In `views_api.py:839`:
+
+```python
+# If fiat currency is provided, use EUR-based format
+if fiat_currency and fiat_amount:
+ # EUR-based posting (current architecture)
+ posting_metadata["sats-equivalent"] = str(abs(line.amount))
+
+ # Apply the sign from line.amount to fiat_amount
+ signed_fiat_amount = fiat_amount if line.amount >= 0 else -fiat_amount
+
+ posting = {
+ "account": account.name,
+ "amount": f"{signed_fiat_amount:.2f} {fiat_currency}",
+ "meta": posting_metadata if posting_metadata else None
+ }
+```
+
+**Critical Details:**
+- `line.amount` is always in satoshis internally
+- The sign (debit/credit) transfers to the fiat amount
+- `sats-equivalent` stores the **absolute value** of the satoshi amount
+- Sign interpretation depends on account type (Asset/Liability/etc.)
+
+---
+
+## Usage: Balance Calculation
+
+### Primary Use Case: User Balances
+
+Castle's core function is tracking **who owes whom** in satoshis. The `sats-equivalent` metadata enables this.
+
+**Flow** (`fava_client.py:220-248`):
+
+```python
+# Parse posting amount (EUR/USD)
+fiat_match = re.match(r'^(-?[\d.]+)\s+([A-Z]{3})$', amount_str)
+if fiat_match and fiat_match.group(2) in ('EUR', 'USD', 'GBP'):
+ fiat_amount = Decimal(fiat_match.group(1))
+ fiat_currency = fiat_match.group(2)
+
+ # Track fiat balance
+ fiat_balances[fiat_currency] += fiat_amount
+
+ # Extract SATS equivalent from metadata
+ posting_meta = posting.get("meta", {})
+ sats_equiv = posting_meta.get("sats-equivalent")
+ if sats_equiv:
+ # Apply the sign from fiat_amount to sats_equiv
+ sats_amount = int(sats_equiv) if fiat_amount > 0 else -int(sats_equiv)
+ total_sats += sats_amount
+```
+
+**Sign Interpretation:**
+- EUR amount is `36.93` (positive/debit) → sats is `+39669`
+- EUR amount is `-36.93` (negative/credit) → sats is `-39669`
+
+### Secondary Use: Journal Entry Display
+
+When displaying transactions to users (`views_api.py:747-751`):
+
+```python
+# Extract sats equivalent from metadata
+posting_meta = first_posting.get("meta", {})
+sats_equiv = posting_meta.get("sats-equivalent")
+if sats_equiv:
+ amount_sats = abs(int(sats_equiv))
+```
+
+This allows the UI to show both EUR and SATS amounts for each transaction.
+
+---
+
+## Why Metadata Instead of Positions?
+
+### The BQL Limitation
+
+Beancount Query Language (BQL) **cannot access metadata**. This means:
+
+```sql
+-- ✅ This works (queries position amounts):
+SELECT account, sum(position) WHERE account ~ 'User-5987ae95'
+-- Returns: EUR positions (not useful for satoshi balances)
+
+-- ❌ This is NOT possible:
+SELECT account, sum(meta["sats-equivalent"]) WHERE account ~ 'User-5987ae95'
+-- Error: BQL cannot access metadata
+```
+
+### Why Castle Accepts This Trade-off
+
+**Performance Analysis** (see `docs/BQL-BALANCE-QUERIES.md`):
+1. **Caching solves the bottleneck**: 60-80% performance improvement from caching account/permission lookups
+2. **Iteration is necessary anyway**: Even with BQL, we'd need to iterate postings to access metadata
+3. **Manual aggregation is fast**: The actual summation is not the bottleneck
+4. **Database queries are the bottleneck**: Solved by Phase 1 caching, not BQL
+
+**Architectural Correctness > Query Performance**:
+- ✅ Transactions recorded in their actual currency
+- ✅ No artificial multi-currency positions
+- ✅ Clean accounting reconciliation
+- ✅ Exchange rate changes don't affect historical records
+
+---
+
+## Alternative Considered: Price Notation
+
+### Price Notation Format (Not Implemented)
+
+```beancount
+2025-11-10 * "Groceries"
+ Expenses:Food -360.00 EUR @@ 337096 SATS
+ Liabilities:Payable:User-abc 360.00 EUR @@ 337096 SATS
+```
+
+**Pros:**
+- ✅ BQL can query prices (enables BQL aggregation)
+- ✅ Standard Beancount syntax
+- ✅ SATS trackable via price database
+
+**Cons:**
+- ❌ Semantically incorrect: `@@` means "total price paid", not "equivalent value"
+- ❌ Implies currency conversion happened (it didn't)
+- ❌ Confuses future readers about transaction nature
+- ❌ Complicates Beancount's price database
+
+**Decision**: Metadata is more semantically correct for "reference value" than price notation.
+
+See `docs/BQL-PRICE-NOTATION-SOLUTION.md` for full analysis.
+
+---
+
+## Data Flow Example
+
+### User Adds Expense
+
+**User Action**: "I paid €36.93 cash for groceries"
+
+**Castle's Internal Representation**:
+```python
+# User provides or Castle calculates:
+fiat_amount = Decimal("36.93") # EUR
+fiat_currency = "EUR"
+amount_sats = 39669 # Calculated from exchange rate
+
+# Create journal entry line:
+line = CreateEntryLine(
+ account_id=expense_account.id,
+ amount=amount_sats, # Internal: always satoshis
+ metadata={
+ "fiat_currency": "EUR",
+ "fiat_amount": "36.93"
+ }
+)
+```
+
+**Beancount Entry Created** (`views_api.py:835-849`):
+```beancount
+2025-11-10 * "Groceries (36.93 EUR)" #expense-entry
+ Expenses:Food:Supplies 36.93 EUR
+ sats-equivalent: "39669"
+ Liabilities:Payable:User-5987ae95 -36.93 EUR
+ sats-equivalent: "39669"
+```
+
+**Balance Calculation** (`fava_client.py:get_user_balance`):
+```python
+# Iterate all postings for user accounts
+# For each posting:
+# - Parse EUR amount: -36.93 EUR (credit to liability)
+# - Extract sats-equivalent: "39669"
+# - Apply sign: -36.93 is negative → sats = -39669
+# - Accumulate: user_balance_sats += -39669
+
+# Result: negative balance = Castle owes user
+```
+
+**User Balance Response**:
+```json
+{
+ "user_id": "5987ae95",
+ "balance": -39669, // Castle owes user 39,669 sats
+ "fiat_balances": {
+ "EUR": "-36.93" // Castle owes user €36.93
+ }
+}
+```
+
+---
+
+## Implementation Details
+
+### Where It's Set
+
+**Primary Location**: `views_api.py:835-849` (Creating journal entries)
+
+All EUR-based postings get `sats-equivalent` metadata:
+- Expense entries (user adds liability)
+- Receivable entries (admin records what user owes)
+- Revenue entries (direct income)
+- Payment entries (settling balances)
+
+### Where It's Read
+
+**Primary Location**: `fava_client.py:239-247` (Balance calculation)
+
+Used in:
+1. `get_user_balance()` - Calculate individual user balance
+2. `get_all_user_balances()` - Calculate all user balances
+3. `get_journal_entries()` - Display transaction amounts
+
+### Data Type and Format
+
+- **Type**: String (Beancount metadata values must be strings or numbers)
+- **Format**: Absolute value, no sign, no decimal point
+- **Examples**:
+ - ✅ `"39669"` (correct)
+ - ✅ `"1000000"` (1M sats)
+ - ❌ `"-39669"` (incorrect: sign goes on EUR amount)
+ - ❌ `"396.69"` (incorrect: satoshis are integers)
+
+---
+
+## Key Principles
+
+### 1. Record in Transaction Currency
+
+```beancount
+# ✅ CORRECT: User paid EUR, record in EUR
+Expenses:Food 36.93 EUR
+ sats-equivalent: "39669"
+
+# ❌ WRONG: Recording Bitcoin when user paid cash
+Expenses:Food 39669 SATS {36.93 EUR}
+```
+
+### 2. Preserve Historical Values
+
+The `sats-equivalent` is the **exact satoshi amount at transaction time**. It does NOT change when exchange rates change.
+
+**Example:**
+- 2025-11-10: User pays €36.93 → 39,669 sats (rate: 1074.19 sats/EUR)
+- 2025-11-15: Exchange rate changes to 1100 sats/EUR
+- **Metadata stays**: `sats-equivalent: "39669"` ✅
+- **If we used current rate**: Would become 40,623 sats ❌
+
+### 3. Separate Fiat and Sats Balances
+
+Castle tracks TWO independent balances:
+- **Satoshi balance**: Sum of `sats-equivalent` metadata (primary)
+- **Fiat balances**: Sum of EUR/USD position amounts (secondary)
+
+These are calculated independently and don't cross-convert.
+
+### 4. Absolute Values in Metadata
+
+The sign (debit/credit) lives on the position amount, NOT the metadata.
+
+```beancount
+# Debit (expense increases):
+Expenses:Food 36.93 EUR # Positive
+ sats-equivalent: "39669" # Absolute value
+
+# Credit (liability increases):
+Liabilities:Payable -36.93 EUR # Negative
+ sats-equivalent: "39669" # Same absolute value
+```
+
+---
+
+## Migration Path
+
+### Future: If We Change to SATS-Primary Format
+
+**Hypothetical future format:**
+```beancount
+; SATS as position, EUR as cost:
+2025-11-10 * "Groceries"
+ Expenses:Food 39669 SATS {36.93 EUR}
+ Liabilities:Payable:User-abc -39669 SATS {36.93 EUR}
+```
+
+**Benefits:**
+- ✅ BQL can query SATS directly
+- ✅ No metadata parsing needed
+- ✅ Standard Beancount cost accounting
+
+**Migration Script** (conceptual):
+```python
+# Read all postings with sats-equivalent metadata
+# For each posting:
+# - Extract sats from metadata
+# - Extract EUR from position
+# - Rewrite as: " SATS { EUR}"
+```
+
+**Decision**: Not implementing now because:
+1. Current architecture is semantically correct
+2. Performance is acceptable with caching
+3. Migration would break existing tooling
+4. EUR-primary aligns with accounting reality
+

+
+## Technical Summary
+
+**Field**: `sats-equivalent`
+**Type**: Metadata (string)
+**Location**: Beancount posting metadata
+**Format**: Absolute satoshi amount as string (e.g., `"39669"`)
+**Purpose**: Track Bitcoin equivalent of fiat transactions
+**Primary Use**: Calculate user satoshi balances
+**Sign Handling**: Inherits from position amount (EUR/USD)
+**Queryable via BQL**: ❌ No (BQL cannot access metadata)
+**Performance**: ✅ Acceptable with caching (60-80% improvement)
+**Architectural Status**: ✅ Current production format
+**Future Migration**: Possible to SATS-primary if needed

+
+## User Experience Flow
+
+### Onboarding New Team Member (Before vs After)
+
+**Before** (10 minutes):
+1. Open permissions page
+2. Click "Grant Permission" 5 times
+3. Fill form each time (user, account, type)
+4. Click grant, repeat
+5. Hope you didn't forget any
+
+**After** (1 minute):
+1. Click "Bulk Operations" → "Copy Permissions"
+2. Select template user → Select new user
+3. Click "Copy"
+4. Done! ✨
+
+**Time Saved**: 90%
+
+---
+
+### Quarterly Access Review (Before vs After)
+
+**Before** (2 hours):
+1. Export permissions to spreadsheet
+2. Manually review each one
+3. Delete expired individually
+4. Update expiration dates one by one
+
+**After** (5 minutes):
+1. Click "Analytics" tab
+2. See "5 Expiring Soon" alert
+3. Review list, click "Extend" on relevant ones
+4. Done! ✨
+
+**Time Saved**: 96%
+

+
+## Testing Plan
+
+### UI Testing
+
+```javascript
+// Test bulk grant
+async function testBulkGrant() {
+ // 1. Open bulk grant dialog
+ // 2. Select 3 users
+ // 3. Select account
+ // 4. Select permission type
+ // 5. Click grant
+ // 6. Verify success message
+ // 7. Verify permissions appear in UI
+}
+
+// Test copy permissions
+async function testCopyPermissions() {
+ // 1. Open copy dialog
+ // 2. Select source user with 5 permissions
+ // 3. Select target user
+ // 4. Filter to SUBMIT_EXPENSE only
+ // 5. Verify preview shows 3 permissions
+ // 6. Click copy
+ // 7. Verify target user has 3 new permissions
+}
+
+// Test analytics
+async function testAnalytics() {
+ // 1. Switch to analytics tab
+ // 2. Verify stats load
+ // 3. Verify charts display
+ // 4. Verify expiring permissions show
+ // 5. Click on expiring permission
+ // 6. Verify details dialog opens
+}
+```
+
+### Integration Testing
+
+```python
+# Test full workflow
+async def test_onboarding_workflow():
+ # 1. Admin syncs accounts
+ sync_result = await api.post("/admin/sync-accounts")
+ assert sync_result["accounts_added"] >= 0
+
+ # 2. Admin copies permissions from template user
+ copy_result = await api.post("/admin/permissions/copy", {
+ "from_user_id": "template",
+ "to_user_id": "new_user"
+ })
+ assert copy_result["copied"] > 0
+
+ # 3. Verify new user has permissions in UI
+ perms = await api.get(f"/admin/permissions?user_id=new_user")
+ assert len(perms) > 0
+
+ # 4. Check analytics reflect new permissions
+ analytics = await api.get("/admin/permissions/analytics")
+ assert analytics["total_permissions"] increased
+```
+

+
+## Accessibility
+
+- ✅ Keyboard navigation support
+- ✅ Screen reader friendly labels
+- ✅ Color contrast compliance (WCAG AA)
+- ✅ Focus indicators
+- ✅ ARIA labels on interactive elements
+
+---
+
+## Mobile Responsiveness
+
+- ✅ Analytics cards stack vertically on mobile
+- ✅ Dialogs are full-screen on small devices
+- ✅ Touch-friendly button sizes
+- ✅ Swipe gestures for tabs
+
+---
+
+## Error Handling
+
+**Bulk Grant Fails:**
+```
+⚠️ Bulk Grant Results
+✅ Granted to 3 users
+❌ Failed for 2 users:
+ • bob: Already has permission
+ • charlie: Account not found
+
+[View Details] [Retry Failed] [Dismiss]
+```
+
+**Account Sync Fails:**
+```
+❌ Account Sync Failed
+Could not connect to Beancount service.
+
+Error: Connection timeout after 10s
+
+[Retry] [Check Settings] [Dismiss]
+```
+
+---
+
+## Performance Considerations
+
+- **Pagination**: Load permissions in batches of 50
+- **Lazy Loading**: Load analytics only when tab is viewed
+- **Debouncing**: Debounce search inputs (300ms)
+- **Caching**: Cache analytics for 30 seconds
+- **Optimistic UI**: Show loading state immediately
+
+---
+
+## Security Considerations
+
+- ✅ All bulk operations require admin key
+- ✅ Confirmation dialogs for destructive actions
+- ✅ Audit log all bulk operations
+- ✅ Rate limiting on API endpoints
+- ✅ CSRF protection on forms
+

+
+**User Guide** (to create):
+1. How to bulk grant permissions
+2. How to copy permissions (templating)
+3. How to offboard a user
+4. How to sync accounts
+5. How to use analytics dashboard
+
+**Admin Guide** (to create):
+1. When to use bulk operations
+2. Best practices for permission templates
+3. How to monitor permission usage
+4. Troubleshooting sync issues
+

+
+## Success Metrics
+
+**Measure after deployment:**
+- Time to onboard new user: 10min → 1min
+- Time for access review: 2hr → 5min
+- Admin satisfaction score: 6/10 → 9/10
+- Support tickets for permissions: -70%
+- Permissions granted per month: +40%
+

+
+## Summary
+
+This UI improvement plan focuses on:
+
+1. **Quick Wins**: Analytics and bulk grant (2-3 days)
+2. **Bulk Operations**: Copy, offboard, sync (2-3 days)
+3. **Polish**: Templates and advanced features (later)
+
+**Total Time**: ~5-6 days for Phase 1 & 2
+**Impact**: 50-70% reduction in admin time
+**ROI**: Immediate productivity boost
+
+The enhancements leverage the new backend features we built (account sync, bulk permission management) and make them accessible through an intuitive UI, significantly improving the admin experience.

+# Castle Beancount Import Helper
+
+Import Beancount ledger transactions into Castle accounting extension.
+
+## 📁 Files
+
+- `import_beancount.py` - Main import script
+- `btc_eur_rates.csv` - Daily BTC/EUR rates (create your own)
+- `README.md` - This file
+
+## 🚀 Setup
+
+### 1. Create BTC/EUR Rates CSV
+
+Create `btc_eur_rates.csv` in this directory with your actual rates:
+
+```csv
+date,btc_eur_rate
+2025-07-01,86500
+2025-07-02,87200
+2025-07-03,87450
+```
+
+### 2. Update User Mappings
+
+Edit `import_beancount.py` and update the `USER_MAPPINGS` dictionary:
+
+```python
+USER_MAPPINGS = {
+ "Pat": "actual_wallet_id_for_pat",
+ "Alice": "actual_wallet_id_for_alice",
+ "Bob": "actual_wallet_id_for_bob",
+}
+```
+
+**How to get wallet IDs:**
+- Check your LNbits admin panel
+- Or query: `curl -X GET http://localhost:5000/api/v1/wallet -H "X-Api-Key: user_invoice_key"`
+
+### 3. Set API Key
+
+```bash
+export CASTLE_ADMIN_KEY="your_lnbits_admin_invoice_key"
+export LNBITS_URL="http://localhost:5000" # Optional
+```
+
+## 📖 Usage
+
+```bash
+cd /path/to/castle/helper
+
+# Test with dry run
+python import_beancount.py ledger.beancount --dry-run
+
+# Actually import
+python import_beancount.py ledger.beancount
+```
+
+## 📄 Beancount File Format
+
+Your Beancount transactions must have an `Equity:` account:
+
+```beancount
+2025-07-06 * "Foix market"
+ Expenses:Groceries 69.40 EUR
+ Equity:Pat
+
+2025-07-07 * "Gas station"
+ Expenses:Transport 45.00 EUR
+ Equity:Alice
+```
+
+**Requirements:**
+- Every transaction must have an `Equity:` account
+- Account names must match exactly what's in Castle
+- The name after `Equity:` must be in `USER_MAPPINGS`
+
+## 🔄 How It Works
+
+1. **Loads rates** from `btc_eur_rates.csv`
+2. **Loads accounts** from Castle API automatically
+3. **Maps users** - Extracts user name from `Equity:Name` accounts
+4. **Parses** Beancount transactions
+5. **Converts** EUR → sats using daily rate
+6. **Uploads** to Castle with metadata
+
+## 📊 Example Output
+
+```bash
+$ python import_beancount.py ledger.beancount
+======================================================================
+🏰 Beancount to Castle Import Script
+======================================================================
+
+📊 Loaded 15 daily rates from btc_eur_rates.csv
+ Date range: 2025-07-01 to 2025-07-15
+
+🏦 Loaded 28 accounts from Castle
+
+👥 User ID mappings:
+ - Pat → wallet_abc123
+ - Alice → wallet_def456
+ - Bob → wallet_ghi789
+
+📄 Found 25 potential transactions in ledger.beancount
+
+✅ Transaction 1: 2025-07-06 - Foix market (User: Pat) (Rate: 87,891 EUR/BTC)
+✅ Transaction 2: 2025-07-07 - Gas station (User: Alice) (Rate: 88,100 EUR/BTC)
+✅ Transaction 3: 2025-07-08 - Restaurant (User: Bob) (Rate: 88,350 EUR/BTC)
+
+======================================================================
+📊 Summary: 25 succeeded, 0 failed, 0 skipped
+======================================================================
+
+✅ Successfully imported 25 transactions to Castle!
+```
+
+## ❓ Troubleshooting
+
+### "No account found in Castle"
+**Error:** `No account found in Castle with name 'Expenses:XYZ'`
+
+**Solution:** Create the account in Castle first with that exact name.
+
+### "No user ID mapping found"
+**Error:** `No user ID mapping found for 'Pat'`
+
+**Solution:** Add Pat to the `USER_MAPPINGS` dictionary in the script.
+
+### "No BTC/EUR rate found"
+**Error:** `No BTC/EUR rate found for 2025-07-15`
+
+**Solution:** Add that date to `btc_eur_rates.csv`.
+
+### "Could not determine user ID"
+**Error:** `Could not determine user ID for transaction`
+
+**Solution:** Every transaction needs an `Equity:` account (e.g., `Equity:Pat`).
+
+## 📝 Transaction Metadata
+
+Each imported transaction includes:
+
+```json
+{
+ "meta": {
+ "source": "beancount_import",
+ "imported_at": "2025-11-08T12:00:00",
+ "btc_eur_rate": 87891.0,
+ "user_id": "wallet_abc123"
+ }
+}
+```
+
+And each line includes:
+
+```json
+{
+ "metadata": {
+ "fiat_currency": "EUR",
+ "fiat_amount": "69.400",
+ "fiat_rate": 1137.88,
+ "btc_rate": 87891.0
+ }
+}
+```
+
+This preserves the original EUR amount and exchange rate for auditing.

+Beancount to Castle Import Script
+
+⚠️ NOTE: This script is for ONE-OFF MIGRATION purposes only.
+
+ Now that Castle uses Fava/Beancount as the single source of truth,
+ the data flow is: Castle → Fava/Beancount (not the reverse).
+
+ This script was used for initial data import from existing Beancount files.
+
+ Future disposition:
+ - DELETE if no longer needed for migrations
+ - REPURPOSE for bidirectional sync if that becomes a requirement
+ - ARCHIVE to misc-docs/old-helpers/ if keeping for reference
+
+Imports Beancount ledger transactions into Castle accounting extension.
+Reads daily BTC/EUR rates from btc_eur_rates.csv in the same directory.

+Castle Extension Database Migrations
+
+This file contains a single squashed migration that creates the complete
+database schema for the Castle extension.
+
+MIGRATION HISTORY:
+This is a squashed migration that combines m001-m016 from the original
+incremental migration history. The complete historical migrations are
+preserved in migrations_old.py.bak for reference.
+
+Key schema decisions reflected in this migration:
+1. Hierarchical Beancount-style account names (e.g., "Assets:Bitcoin:Lightning")
+2. No journal_entries/entry_lines tables (Fava is source of truth)
+3. User-specific equity accounts created dynamically (Equity:User-{user_id})
+4. Parent-only accounts removed (hierarchy implicit in colon-separated names)
+5. Multi-currency support via balance_assertions
+6. Granular permission system via account_permissions
+
+Original migration sequence (Nov 2025):
+- m001: Initial accounts, journal_entries, entry_lines tables
+- m002: Extension settings
+- m003: User wallet settings
+- m004: Manual payment requests
+- m005: Added flag/meta to journal entries
+- m006: Migrated to hierarchical account names
+- m007: Balance assertions
+- m008: Renamed Lightning account
+- m009: Added OnChain Bitcoin account
+- m010: User equity status
+- m011: Account permissions
+- m012: Updated default accounts with detailed hierarchy
+- m013: Removed parent-only accounts (Assets:Bitcoin, Equity)
+- m014: Removed legacy equity accounts (MemberEquity, RetainedEarnings)
+- m015: Converted entry_lines to single amount field
+- m016: Dropped journal_entries and entry_lines tables (Fava integration)

Create Balance Assertion
- Balance assertions help you verify accounting accuracy by checking if an account's actual balance matches your expected balance. If the assertion fails, you'll be alerted to investigate the discrepancy.
+ Balance assertions are written to your Beancount ledger and validated automatically by Beancount.
+ This verifies that an account's actual balance matches your expected balance at a specific date.
+ If the assertion fails, Beancount will alert you to investigate the discrepancy. Castle stores
+ metadata (tolerance, notes) for your convenience.
