+# Automated Daily Reconciliation
+
+The Castle extension includes automated daily balance checking to ensure accounting accuracy.
+
+## Overview
+
+The daily reconciliation task:
+- Checks all balance assertions
+- Identifies discrepancies
+- Logs results
+- Can send alerts (future enhancement)
+
+## Manual Trigger
+
+You can manually trigger the reconciliation check from the UI or via API:
+
+### Via API
+```bash
+curl -X POST https://your-lnbits-instance.com/castle/api/v1/tasks/daily-reconciliation \
+  -H "X-Api-Key: YOUR_ADMIN_KEY"
+```
+
+## Automated Scheduling
+
+### Option 1: Cron Job (Recommended)
+
+Add to your crontab:
+
+```bash
+# Run daily at 2 AM
+0 2 * * * curl -X POST http://localhost:5000/castle/api/v1/tasks/daily-reconciliation -H "X-Api-Key: YOUR_ADMIN_KEY" >> /var/log/castle-reconciliation.log 2>&1
+```
+
+To edit crontab:
+```bash
+crontab -e
+```
+
+### Option 2: Systemd Timer
+
+Create `/etc/systemd/system/castle-reconciliation.service`:
+```ini
+[Unit]
+Description=Castle Daily Reconciliation Check
+After=network.target
+
+[Service]
+Type=oneshot
+User=lnbits
+ExecStart=/usr/bin/curl -X POST http://localhost:5000/castle/api/v1/tasks/daily-reconciliation -H "X-Api-Key: YOUR_ADMIN_KEY"
+```
+
+Create `/etc/systemd/system/castle-reconciliation.timer`:
+```ini
+[Unit]
+Description=Run Castle reconciliation daily
+
+[Timer]
+OnCalendar=daily
+OnCalendar=02:00
+Persistent=true
+
+[Install]
+WantedBy=timers.target
+```
+
+Enable and start:
+```bash
+sudo systemctl enable castle-reconciliation.timer
+sudo systemctl start castle-reconciliation.timer
+```
+
+### Option 3: Docker/Kubernetes CronJob
+
+For containerized deployments:
+
+```yaml
+apiVersion: batch/v1
+kind: CronJob
+metadata:
+  name: castle-reconciliation
+spec:
+  schedule: "0 2 * * *"  # Daily at 2 AM
+  jobTemplate:
+    spec:
+      template:
+        spec:
+          containers:
+          - name: reconciliation
+            image: curlimages/curl:latest
+            args:
+            - /bin/sh
+            - -c
+            - curl -X POST http://lnbits:5000/castle/api/v1/tasks/daily-reconciliation -H "X-Api-Key: ${ADMIN_KEY}"
+          restartPolicy: OnFailure
+```
+
+## Response Format
+
+The endpoint returns:
+
+```json
+{
+  "task_id": "abc123",
+  "timestamp": "2025-10-23T02:00:00",
+  "total": 15,
+  "checked": 15,
+  "passed": 14,
+  "failed": 1,
+  "errors": 0,
+  "failed_assertions": [
+    {
+      "id": "assertion_id",
+      "account_id": "account_id",
+      "expected_sats": 100000,
+      "actual_sats": 99500,
+      "difference_sats": -500
+    }
+  ]
+}
+```
+
+## Monitoring
+
+### Check Logs
+
+```bash
+# View cron logs
+grep CRON /var/log/syslog
+
+# View custom log (if using cron with redirect)
+tail -f /var/log/castle-reconciliation.log
+```
+
+### Success Criteria
+
+- `failed: 0` - All assertions passed
+- `errors: 0` - No errors during checks
+- `checked === total` - All assertions were checked
+
+### Failure Scenarios
+
+If `failed > 0`:
+1. Check the `failed_assertions` array for details
+2. Investigate discrepancies in the Castle UI
+3. Review recent transactions
+4. Check for data entry errors
+5. Verify exchange rate conversions (for fiat)
+
+## Future Enhancements
+
+Planned features:
+- [ ] Email notifications on failures
+- [ ] Webhook notifications
+- [ ] Slack/Discord integration
+- [ ] Configurable schedule from UI
+- [ ] Historical reconciliation reports
+- [ ] Automatic retry on transient errors
+
+## Troubleshooting
+
+### Task Not Running
+
+1. **Check cron service**:
+   ```bash
+   sudo systemctl status cron
+   ```
+
+2. **Verify API key**:
+   - Ensure you're using the admin wallet API key
+   - Key must belong to the super user
+
+3. **Check network connectivity**:
+   ```bash
+   curl http://localhost:5000/castle/api/v1/reconciliation/summary -H "X-Api-Key: YOUR_KEY"
+   ```
+
+### Permission Denied
+
+- Ensure the user running cron has execute permissions
+- Check file permissions on any scripts
+- Verify API key is valid and belongs to super user
+
+### High Failure Rate
+
+- Review your balance assertions
+- Some assertions may need tolerance adjustments
+- Check for recent changes in exchange rates
+- Verify all transactions are properly cleared
+
+## Best Practices
+
+1. **Set Reasonable Tolerances**: Use tolerance levels to account for rounding
+2. **Regular Review**: Check reconciliation dashboard weekly
+3. **Assertion Coverage**: Create assertions for critical accounts
+4. **Maintenance Window**: Run reconciliation during low-activity periods
+5. **Backup First**: Run manual check before configuring automation
+6. **Monitor Logs**: Set up log rotation and monitoring
+7. **Alert Integration**: Plan for notification system integration
+
+## Example Setup Script
+
+```bash
+#!/bin/bash
+# setup-castle-reconciliation.sh
+
+# Configuration
+LNBITS_URL="http://localhost:5000"
+ADMIN_KEY="your_admin_key_here"
+LOG_FILE="/var/log/castle-reconciliation.log"
+
+# Create log file
+touch "$LOG_FILE"
+chmod 644 "$LOG_FILE"
+
+# Add cron job
+(crontab -l 2>/dev/null; echo "0 2 * * * curl -X POST $LNBITS_URL/castle/api/v1/tasks/daily-reconciliation -H 'X-Api-Key: $ADMIN_KEY' >> $LOG_FILE 2>&1") | crontab -
+
+echo "Daily reconciliation scheduled for 2 AM"
+echo "Logs will be written to: $LOG_FILE"
+
+# Test the endpoint
+echo "Running test reconciliation..."
+curl -X POST "$LNBITS_URL/castle/api/v1/tasks/daily-reconciliation" \
+  -H "X-Api-Key: $ADMIN_KEY"
+```
+
+Make executable and run:
+```bash
+chmod +x setup-castle-reconciliation.sh
+./setup-castle-reconciliation.sh
+```

+# Phase 2: Reconciliation - COMPLETE ✅
+
+## Summary
+
+Phase 2 of the Beancount-inspired refactor focused on **reconciliation and automated balance checking**. This phase builds on Phase 1's foundation to provide robust reconciliation tools that ensure accounting accuracy and catch discrepancies early.
+
+## Completed Features
+
+### 1. Balance Assertions ✅
+
+**Purpose**: Verify account balances match expected values at specific points in time (like Beancount's `balance` directive)
+
+**Implementation**:
+- **Models** (`models.py:184-219`):
+  - `AssertionStatus` enum (pending, passed, failed)
+  - `BalanceAssertion` model with sats and optional fiat checks
+  - `CreateBalanceAssertion` request model
+
+- **Database** (`migrations.py:275-320`):
+  - `balance_assertions` table with expected/actual balance tracking
+  - Tolerance levels for flexible matching
+  - Status tracking and timestamps
+  - Indexes for performance
+
+- **CRUD** (`crud.py:773-981`):
+  - `create_balance_assertion()` - Create and store assertion
+  - `get_balance_assertion()` - Fetch single assertion
+  - `get_balance_assertions()` - List with filters
+  - `check_balance_assertion()` - Compare expected vs actual
+  - `delete_balance_assertion()` - Remove assertion
+
+- **API Endpoints** (`views_api.py:1067-1230`):
+  - `POST /api/v1/assertions` - Create and check assertion
+  - `GET /api/v1/assertions` - List assertions with filters
+  - `GET /api/v1/assertions/{id}` - Get specific assertion
+  - `POST /api/v1/assertions/{id}/check` - Re-check assertion
+  - `DELETE /api/v1/assertions/{id}` - Delete assertion
+
+- **UI** (`templates/castle/index.html:254-378`):
+  - Balance Assertions card (super user only)
+  - Failed assertions prominently displayed with red banner
+  - Passed assertions in collapsible panel
+  - Create assertion dialog with validation
+  - Re-check and delete buttons
+
+- **Frontend** (`static/js/index.js:70-79, 602-726`):
+  - Data properties and computed values
+  - CRUD methods for assertions
+  - Automatic loading on page load
+
+### 2. Reconciliation API Endpoints ✅
+
+**Purpose**: Provide comprehensive reconciliation tools and reporting
+
+**Implementation**:
+- **Summary Endpoint** (`views_api.py:1236-1287`):
+  - `GET /api/v1/reconciliation/summary`
+  - Returns counts of assertions by status
+  - Returns counts of journal entries by flag
+  - Total accounts count
+  - Last checked timestamp
+
+- **Check All Endpoint** (`views_api.py:1290-1325`):
+  - `POST /api/v1/reconciliation/check-all`
+  - Re-checks all balance assertions
+  - Returns summary of results (passed/failed/errors)
+  - Useful for manual reconciliation runs
+
+- **Discrepancies Endpoint** (`views_api.py:1328-1357`):
+  - `GET /api/v1/reconciliation/discrepancies`
+  - Returns all failed assertions
+  - Returns all flagged journal entries
+  - Returns all pending entries
+  - Total discrepancy count
+
+### 3. Reconciliation UI Dashboard ✅
+
+**Purpose**: Visual dashboard for reconciliation status and quick access to reconciliation tools
+
+**Implementation** (`templates/castle/index.html:380-499`):
+- **Summary Cards**:
+  - Balance Assertions stats (total, passed, failed, pending)
+  - Journal Entries stats (total, cleared, pending, flagged)
+  - Total Accounts count with last checked timestamp
+
+- **Discrepancies Alert**:
+  - Warning banner when discrepancies found
+  - Shows count of failed assertions and flagged entries
+  - "View Details" button to expand discrepancy list
+
+- **Discrepancy Details**:
+  - Failed assertions list with expected vs actual balances
+  - Flagged entries list
+  - Quick access to problematic transactions
+
+- **Actions**:
+  - "Check All" button to run full reconciliation
+  - Loading states during checks
+  - Success message when all accounts reconciled
+
+**Frontend** (`static/js/index.js:80-85, 727-779, 933-934`):
+- Reconciliation data properties
+- Methods to load summary and discrepancies
+- `runFullReconciliation()` method with notifications
+- Automatic loading on page load for super users
+
+### 4. Automated Daily Balance Checks ✅
+
+**Purpose**: Run balance checks automatically on a schedule to catch discrepancies early
+
+**Implementation**:
+
+- **Tasks Module** (`tasks.py`):
+  - `check_all_balance_assertions()` - Core checking logic
+  - `scheduled_daily_reconciliation()` - Scheduled wrapper
+  - Results logging and reporting
+  - Error handling
+
+- **API Endpoint** (`views_api.py:1363-1390`):
+  - `POST /api/v1/tasks/daily-reconciliation`
+  - Can be triggered manually or via cron
+  - Returns detailed results
+  - Super user only
+
+- **Documentation** (`DAILY_RECONCILIATION.md`):
+  - Comprehensive setup guide
+  - Multiple scheduling options (cron, systemd, k8s)
+  - Monitoring and troubleshooting
+  - Best practices
+  - Example scripts
+
