bump to v0.24.5

- Bumped p256k1.mleku.dev version from v1.0.1 to v1.0.3 in go.mod and updated go.sum accordingly.
- Updated deployment script to use Go version 1.25.3 and adjusted CGO settings for building the binary.
- Added new lines to POLICY_USAGE_GUIDE.md and RELAY_TESTING_GUIDE.md for improved documentation clarity.

+```
+
+## Testing Strategy
+
+### Development Testing
+
+During development, run tests frequently:
+
+```bash
+# Quick test against local relay
+go run ./cmd/relay-tester -url ws://127.0.0.1:3334
+
+# Test specific functionality
+go run ./cmd/relay-tester -url ws://127.0.0.1:3334 -test "EOSE handling"
+```
+
+### CI/CD Integration
+
+For automated testing in CI/CD pipelines:
+
+```bash
+# JSON output for parsing
+relay-tester -url $RELAY_URL -json > test_results.json
+
+# Check exit code
+if [ $? -eq 0 ]; then
+  echo "All tests passed!"
+else
+  echo "Some tests failed"
+  cat test_results.json
+  exit 1
+fi
+```
+
+### Performance Testing
+
+The relay-tester can be combined with performance testing:
+
+```bash
+# Start relay
+./orly &
+RELAY_PID=$!
+
+# Run compliance tests
+relay-tester -url ws://127.0.0.1:3334
+
+# Run performance tests
+./scripts/runtests.sh
+
+# Cleanup
+kill $RELAY_PID
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Connection Refused**: Ensure relay is running and accessible
+2. **Timeout Errors**: Increase timeout with `-timeout` flag
+3. **Authentication Required**: Some relays require NIP-42 AUTH
+4. **WebSocket Errors**: Check firewall and network configuration
+
+### Debug Output
+
+Use verbose mode for detailed information:
+
+```bash
+relay-tester -url ws://127.0.0.1:3334 -v
+```
+
+### Test Dependencies
+
+Tests are run in dependency order. If a foundational test fails, subsequent tests may also fail. Always fix basic event publishing before debugging complex filtering.
+
+## Development
+
+### Running Tests
+
+```bash
+# Run relay-tester unit tests
+go test ./cmd/relay-tester
+
+# Run all tests including relay-tester
+go test ./...
+
+# Run with coverage
+go test -cover ./cmd/relay-tester
+```
+

+Cluster Replication Protocol
+----------------------------
+
+`draft` `optional`
+
+## Abstract
+
+This NIP defines an HTTP-based pull replication protocol for relay clusters. It enables relay operators to form distributed networks where relays actively poll each other to synchronize events, providing efficient traffic patterns and improved data availability. Cluster membership is managed by designated cluster administrators who publish membership lists that relays replicate and use to update their polling targets.
+
+## Motivation
+
+Current Nostr relay implementations operate independently, leading to fragmented event storage across the network. Users must manually configure multiple relays to ensure their events are widely available. This creates several problems:
+
+1. **Event Availability**: Important events may not be available on all relays a user wants to interact with
+2. **Manual Synchronization**: Users must manually publish events to multiple relays
+3. **Discovery Issues**: Clients have difficulty finding complete event histories
+4. **Resource Inefficiency**: Relays store duplicate events without coordination
+5. **Network Fragmentation**: Related events become scattered across disconnected relays
+
+This NIP addresses these issues by enabling relay operators to form clusters that actively replicate events using efficient HTTP polling mechanisms, creating more resilient and bandwidth-efficient event distribution networks.
+
+## Specification
+
+### Event Kinds
+
+This NIP defines the following new event kinds:
+
+| Kind | Description |
+|------|-------------|
+| `39108` | Cluster Membership List |
+
+### Cluster Membership List (Kind 39108)
+
+Cluster administrators publish this replaceable event to define the current set of cluster members. All cluster relays replicate this event and update their polling lists when it changes:
+
+```json
+{
+  "kind": 39108,
+  "content": "{\"name\":\"My Cluster\",\"description\":\"Community relay cluster\"}",
+  "tags": [
+    ["d", "membership"],
+    ["relay", "https://relay1.example.com/", "wss://relay1.example.com/"],
+    ["relay", "https://relay2.example.com/", "wss://relay2.example.com/"],
+    ["relay", "https://relay3.example.com/", "wss://relay3.example.com/"],
+    ["version", "1"]
+  ],
+  "pubkey": "<admin-pubkey-hex>",
+  "created_at": <unix-timestamp>,
+  "id": "<event-id>",
+  "sig": "<signature>"
+}
+```
+
+**Tags:**
+- `d`: Identifier for the membership list (always "membership")
+- `relay`: HTTP and WebSocket URLs of cluster member relays (comma-separated)
+- `version`: Protocol version number
+
+**Content:** JSON object containing cluster metadata (name, description)
+
+**Authorization:** Only events signed by cluster administrators are valid for membership updates. Cluster administrators are designated through static relay configuration and cannot be modified by membership events.
+
+### HTTP API Endpoints
+
+#### 1. Latest Serial Endpoint
+
+Returns the current highest event serial number in the relay's database.
+
+**Endpoint:** `GET /cluster/latest`
+
+**Response:**
+```json
+{
+  "serial": 12345678,
+  "timestamp": 1640995200
+}
+```
+
+**Parameters:**
+- `serial`: The highest event serial number in the database
+- `timestamp`: Unix timestamp when this serial was last updated
+
+#### 2. Event IDs by Serial Range Endpoint
+
+Returns event IDs for a range of serial numbers.
+
+**Endpoint:** `GET /cluster/events`
+
+**Query Parameters:**
+- `from`: Starting serial number (inclusive)
+- `to`: Ending serial number (inclusive)
+- `limit`: Maximum number of event IDs to return (default: 1000, max: 10000)
+
+**Response:**
+```json
+{
+  "events": [
+    {
+      "serial": 12345670,
+      "id": "abc123...",
+      "timestamp": 1640995100
+    },
+    {
+      "serial": 12345671,
+      "id": "def456...",
+      "timestamp": 1640995110
+    }
+  ],
+  "has_more": false,
+  "next_from": null
+}
+```
+
+**Response Fields:**
+- `events`: Array of event objects with serial, id, and timestamp
+- `has_more`: Boolean indicating if there are more results
+- `next_from`: Serial number to use as `from` parameter for next request (if `has_more` is true)
+
+### Replication Protocol
+
+#### 1. Cluster Discovery
+
+1. Cluster administrators publish Kind 39108 events defining cluster membership
+2. Relays configured with cluster admin npubs subscribe to these events
+3. When membership updates are received, relays update their polling lists
+4. Polling begins immediately with 5-second intervals to all listed relays
+
+#### 2. Active Replication Process
+
+Each relay maintains a replication state for each cluster peer:
+
+1. **Poll Latest Serial**: Every 5 seconds, query `/cluster/latest` from each peer
+2. **Compare Serials**: If peer has higher serial than local replication state, fetch missing events
+3. **Fetch Event IDs**: Use `/cluster/events` to get event IDs in the serial range gap
+4. **Fetch Full Events**: Use standard WebSocket REQ messages to get full event data
+5. **Store Events**: Validate and store events in local database (relays MAY choose not to store every event they receive)
+6. **Update State**: Record the highest successfully replicated serial for each peer
+
+#### 3. Serial Number Management
+
+Each relay maintains an internal serial number that increments with each stored event:
+
+- **Serial Assignment**: Events are assigned serial numbers in the order they are stored
+- **Monotonic Increase**: Serial numbers only increase, never decrease
+- **Gap Handling**: Missing serials are handled gracefully
+- **Peer State Tracking**: Each relay tracks the last replicated serial from each peer
+- **Restart Recovery**: On restart, relays load persisted serial state and resume replication from the last processed serial
+
+#### 4. Conflict Resolution
+
+When fetching events that already exist locally:
+
+1. **Serial Consistency**: If serial numbers match, events should be identical
+2. **Timestamp Priority**: For conflicting events, newer timestamps take precedence
+3. **Signature Verification**: Invalid signatures always result in rejection
+4. **Author Authority**: Original author events override third-party copies
+5. **Event Kind Rules**: Follow NIP-01 replaceable event semantics where applicable
+

+     |                        |                          |
+```
+
+## Security Considerations
+
+1. **Administrator Authorization**: Only cluster administrators can modify membership lists
+2. **Transport Security**: HTTP endpoints SHOULD use HTTPS for secure communication
+3. **Rate Limiting**: Implement rate limiting on polling endpoints to prevent abuse
+4. **Event Validation**: All fetched events MUST be fully validated before storage
+5. **Access Control**: HTTP endpoints SHOULD implement proper access controls
+6. **Privacy**: Membership lists contain relay addresses but no sensitive user data
+7. **Audit Logging**: All replication operations SHOULD be logged for monitoring
+8. **Network Isolation**: Clusters SHOULD be isolated from public relay operations
+9. **Serial Consistency**: Serial numbers help detect tampering or data corruption
+
+## Implementation Guidelines
+
+### Relay Operators
+
+1. Configure cluster administrator npubs to monitor membership updates
+2. Implement HTTP endpoints for `/cluster/latest` and `/cluster/events`
+3. Set up 5-second polling intervals to all cluster peers
+4. Implement peer state persistence to track last processed serials
+5. Monitor replication health and alert on failures
+6. Handle cluster membership changes gracefully (cleaning up removed peer state)
+7. Implement proper serial number management
+8. Document cluster configuration
+
+### Client Developers
+
+1. Clients MAY display cluster membership information for relay discovery
+2. Clients SHOULD prefer cluster relays for improved event availability
+3. Clients can use membership events to find additional relay options
+4. Clients SHOULD handle relay failures within clusters gracefully
+
+## Backwards Compatibility
+
+This NIP is fully backwards compatible:
+
+- Relays not implementing this NIP continue to operate normally
+- The HTTP endpoints are optional additions to existing relay functionality
+- Standard WebSocket event fetching continues to work unchanged
+- Users can continue using relays without cluster participation
+- Existing event kinds and message types are unchanged
+
+## Reference Implementation
+
+A reference implementation SHOULD include:
+
+1. HTTP endpoint handlers for `/cluster/latest` and `/cluster/events`
+2. Cluster membership subscription and parsing logic
+3. Replication polling scheduler with 5-second intervals
+4. Serial number management and tracking
+5. Peer state persistence and recovery (last known serials stored in database)
+6. Peer state management and failure handling
+7. Configuration management for cluster settings
+

+# ORLY Policy System Usage Guide
+
+The ORLY relay implements a comprehensive policy system that provides fine-grained control over event storage and retrieval. This guide explains how to configure and use the policy system to implement custom relay behavior.
+
+## Overview
+
+The policy system allows relay operators to:
+
+- Control which events are stored and retrieved
+- Implement custom validation logic
+- Set size and age limits for events
+- Define access control based on pubkeys
+- Use scripts for complex policy rules
+- Filter events by content, kind, or other criteria
+
+## Quick Start
+
+### 1. Enable the Policy System
+
+Set the environment variable to enable policy checking:
+
+```bash
+export ORLY_POLICY_ENABLED=true
+```
+
+### 2. Create a Policy Configuration
+
+Create the policy file at `~/.config/ORLY/policy.json`:
+
+```json
+{
+  "default_policy": "allow",
+  "global": {
+    "max_age_of_event": 86400,
+    "max_age_event_in_future": 300,
+    "size_limit": 100000
+  },
+  "rules": {
+    "1": {
+      "description": "Text notes - basic validation",
+      "max_age_of_event": 3600,
+      "size_limit": 32000
+    }
+  }
+}
+```
+
+### 3. Restart the Relay
+
+```bash
+# Restart your relay to load the policy
+sudo systemctl restart orly
+```
+
+## Configuration Structure
+
+### Top-Level Configuration
+
+```json
+{
+  "default_policy": "allow|deny",
+  "kind": {
+    "whitelist": ["1", "3", "4"],
+    "blacklist": []
+  },
+  "global": { ... },
+  "rules": { ... }
+}
+```
+
+### default_policy
+
+Determines the fallback behavior when no specific rules apply:
+
+- `"allow"`: Allow events unless explicitly denied (default)
+- `"deny"`: Deny events unless explicitly allowed
+
+### kind Filtering
+
+Controls which event kinds are processed:
+
+```json
+"kind": {
+  "whitelist": ["1", "3", "4", "9735"],
+  "blacklist": []
+}
+```
+
+- `whitelist`: Only these kinds are allowed (if present)
+- `blacklist`: These kinds are denied (if present)
+- Empty arrays allow all kinds
+
+### Global Rules
+
+Rules that apply to **all events** regardless of kind:
+
+```json
+"global": {
+  "description": "Site-wide security rules",
+  "write_allow": [],
+  "write_deny": [],
+  "read_allow": [],
+  "read_deny": [],
+  "size_limit": 100000,
+  "content_limit": 50000,
+  "max_age_of_event": 86400,
+  "max_age_event_in_future": 300,
+  "privileged": false
+}
+```
+
+### Kind-Specific Rules
+
+Rules that apply to specific event kinds:
+
+```json
+"rules": {
+  "1": {
+    "description": "Text notes",
+    "write_allow": [],
+    "write_deny": [],
+    "read_allow": [],
+    "read_deny": [],
+    "size_limit": 32000,
+    "content_limit": 10000,
+    "max_age_of_event": 3600,
+    "max_age_event_in_future": 60,
+    "privileged": false
+  }
+}
+```
+
+## Policy Fields
+
+### Access Control
+
+#### write_allow / write_deny
+
+Control who can publish events:
+
+```json
+{
+  "write_allow": ["npub1allowed...", "npub1another..."],
+  "write_deny": ["npub1blocked..."]
+}
+```
+
+- `write_allow`: Only these pubkeys can write (empty = allow all)
+- `write_deny`: These pubkeys cannot write
+
+#### read_allow / read_deny
+
+Control who can read events:
+
+```json
+{
+  "read_allow": ["npub1trusted..."],
+  "read_deny": ["npub1suspicious..."]
+}
+```
+
+- `read_allow`: Only these pubkeys can read (empty = allow all)
+- `read_deny`: These pubkeys cannot read
+
+### Size Limits
+
+#### size_limit
+
+Maximum total event size in bytes:
+
+```json
+{
+  "size_limit": 32000
+}
+```
+
+Includes ID, pubkey, sig, tags, content, and metadata.
+
+#### content_limit
+
+Maximum content field size in bytes:
+
+```json
+{
+  "content_limit": 10000
+}
+```
+
+Only applies to the `content` field.
+
+### Age Validation
+
+#### max_age_of_event
+
+Maximum age of events in seconds (prevents replay attacks):
+
+```json
+{
+  "max_age_of_event": 3600
+}
+```
+
+Events older than `current_time - max_age_of_event` are rejected.
+
+#### max_age_event_in_future
+
+Maximum time events can be in the future in seconds:
+
+```json
+{
+  "max_age_event_in_future": 300
+}
+```
+
+Events with `created_at > current_time + max_age_event_in_future` are rejected.
+
+### Advanced Options
+
+#### privileged
+
+Require events to be authored by authenticated users or contain authenticated users in p-tags:
+
+```json
+{
+  "privileged": true
+}
+```
+
+Useful for private content that should only be accessible to specific users.
+
+#### script
+
+Path to a custom script for complex validation logic:
+
+```json
+{
+  "script": "/path/to/custom-policy.sh"
+}
+```
+
+See the script section below for details.
+
+## Policy Scripts
+
+For complex validation logic, use custom scripts that receive events via stdin and return decisions via stdout.
+
+### Script Interface
+
+**Input**: JSON event objects, one per line:
+
+```json
+{
+  "id": "event_id",
+  "pubkey": "author_pubkey",
+  "kind": 1,
+  "content": "Hello, world!",
+  "tags": [["p", "recipient"]],
+  "created_at": 1640995200,
+  "sig": "signature"
+}
+```
+
+Additional fields provided:
+- `logged_in_pubkey`: Hex pubkey of authenticated user (if any)
+- `ip_address`: Client IP address
+
+**Output**: JSONL responses:
+
+```json
+{"id": "event_id", "action": "accept", "msg": ""}
+{"id": "event_id", "action": "reject", "msg": "Blocked content"}
+{"id": "event_id", "action": "shadowReject", "msg": ""}
+```
+
+### Actions
+
+- `accept`: Store/retrieve the event normally
+- `reject`: Reject with OK=false and message
+- `shadowReject`: Accept with OK=true but don't store (useful for spam filtering)
+
+### Example Scripts
+
+#### Bash Script
+
+```bash
+#!/bin/bash
+while read -r line; do
+    if [[ -n "$line" ]]; then
+        event_id=$(echo "$line" | jq -r '.id')
+
+        # Check for spam content
+        if echo "$line" | jq -r '.content' | grep -qi "spam"; then
+            echo "{\"id\":\"$event_id\",\"action\":\"reject\",\"msg\":\"Spam detected\"}"
+        else
+            echo "{\"id\":\"$event_id\",\"action\":\"accept\",\"msg\":\"\"}"
+        fi
+    fi
+done
+```
+
+#### Python Script
+
+```python
+#!/usr/bin/env python3
+import json
+import sys
+
+def process_event(event):
+    event_id = event.get('id', '')
+    content = event.get('content', '')
+    pubkey = event.get('pubkey', '')
+    logged_in = event.get('logged_in_pubkey', '')
+
+    # Block spam
+    if 'spam' in content.lower():
+        return {
+            'id': event_id,
+            'action': 'reject',
+            'msg': 'Content contains spam'
+        }
+
+    # Require authentication for certain content
+    if 'private' in content.lower() and not logged_in:
+        return {
+            'id': event_id,
+            'action': 'reject',
+            'msg': 'Authentication required'
+        }
+
+    return {
+        'id': event_id,
+        'action': 'accept',
+        'msg': ''
+    }
+
+for line in sys.stdin:
+    if line.strip():
+        try:
+            event = json.loads(line)
+            response = process_event(event)
+            print(json.dumps(response))
+            sys.stdout.flush()
+        except json.JSONDecodeError:
+            continue
+```
+
+### Script Configuration
+
+Place scripts in a secure location and reference them in policy:
+
+```json
+{
+  "rules": {
+    "1": {
+      "script": "/etc/orly/policy/text-note-policy.py",
+      "description": "Custom validation for text notes"
+    }
+  }
+}
+```
+
+Ensure scripts are executable and have appropriate permissions.
+
+## Policy Evaluation Order
+
+Events are evaluated in this order:
+
+1. **Global Rules** - Applied first to all events
+2. **Kind Filtering** - Whitelist/blacklist check
+3. **Kind-specific Rules** - Rules for the event's kind
+4. **Script Rules** - Custom script logic (if configured)
+5. **Default Policy** - Fallback behavior
+
+The first rule that makes a decision (allow/deny) stops evaluation.
+
+## Event Processing Integration
+
+### Write Operations (EVENT)
+
+When `ORLY_POLICY_ENABLED=true`, each incoming EVENT is checked:
+
+```go
+// Pseudo-code for policy integration
+func handleEvent(event *Event, client *Client) {
+    decision := policy.CheckPolicy("write", event, client.Pubkey, client.IP)
+    if decision.Action == "reject" {
+        client.SendOK(event.ID, false, decision.Message)
+        return
+    }
+    if decision.Action == "shadowReject" {
+        client.SendOK(event.ID, true, "")
+        return
+    }
+    // Store event
+    storeEvent(event)
+    client.SendOK(event.ID, true, "")
+}
+```
+
+### Read Operations (REQ)
+
+Events returned in REQ responses are filtered:
+
+```go
+func handleReq(filter *Filter, client *Client) {
+    events := queryEvents(filter)
+    filteredEvents := []Event{}
+
+    for _, event := range events {
+        decision := policy.CheckPolicy("read", &event, client.Pubkey, client.IP)
+        if decision.Action != "reject" {
+            filteredEvents = append(filteredEvents, event)
+        }
+    }
+
+    sendEvents(client, filteredEvents)
+}
+```
+
+## Common Use Cases
+
+### Basic Spam Filtering
+
+```json
+{
+  "global": {
+    "max_age_of_event": 86400,
+    "size_limit": 100000
+  },
+  "rules": {
+    "1": {
+      "script": "/etc/orly/scripts/spam-filter.sh",
+      "max_age_of_event": 3600,
+      "size_limit": 32000
+    }
+  }
+}
+```
+
+### Private Relay
+
+```json
+{
+  "default_policy": "deny",
+  "global": {
+    "write_allow": ["npub1trusted1...", "npub1trusted2..."],
+    "read_allow": ["npub1trusted1...", "npub1trusted2..."]
+  }
+}
+```
+
+### Content Moderation
+
+```json
+{
+  "rules": {
+    "1": {
+      "script": "/etc/orly/scripts/content-moderation.py",
+      "description": "AI-powered content moderation"
+    }
+  }
+}
+```
+
+### Rate Limiting
+
+```json
+{
+  "global": {
+    "script": "/etc/orly/scripts/rate-limiter.sh"
+  }
+}
+```
+
+### Follows-Based Access
+
+Combined with ACL system:
+
+```bash
+export ORLY_ACL_MODE=follows
+export ORLY_ADMINS=npub1admin1...,npub1admin2...
+export ORLY_POLICY_ENABLED=true
+```
+
+## Monitoring and Debugging
+
+### Log Messages
+
+Policy decisions are logged:
+
+```
+policy allowed event <id>
+policy rejected event <id>: reason
+policy filtered out event <id> for read access
+```
+
+### Script Health
+
+Script failures are logged:
+
+```
+policy rule for kind <N> is inactive (script not running), falling back to default policy (allow)
+policy rule for kind <N> failed (script processing error: timeout), falling back to default policy (allow)
+```
+
+### Testing Policies
+
+Use the policy test tools:
+
+```bash
+# Test policy with sample events
+./scripts/run-policy-test.sh
+
+# Test policy filter integration
+./scripts/run-policy-filter-test.sh
+```
+
+### Debugging Scripts
+
+Test scripts independently:
+
+```bash
+# Test script with sample event
+echo '{"id":"test","kind":1,"content":"test message"}' | ./policy-script.sh
+
+# Expected output:
+# {"id":"test","action":"accept","msg":""}
+```
+
+## Performance Considerations
+
+### Script Performance
+
+- Scripts run synchronously and can block event processing
+- Keep script logic efficient (< 100ms per event)
+- Consider using `shadowReject` for non-blocking filtering
+- Scripts should handle malformed input gracefully
+
+### Memory Usage
+
+- Policy configuration is loaded once at startup
+- Scripts are kept running for performance
+- Large configurations may impact startup time
+
+### Scaling
+
+- For high-throughput relays, prefer built-in policy rules over scripts
+- Use script timeouts to prevent hanging
+- Monitor script performance and resource usage
+
+## Security Considerations
+
+### Script Security
+
+- Scripts run with relay process privileges
+- Validate all inputs in scripts
+- Use secure file permissions for policy files
+- Regularly audit custom scripts
+
+### Access Control
+
+- Test policy rules thoroughly before production use
+- Use `privileged: true` for sensitive content
+- Combine with authentication requirements
+- Log policy violations for monitoring
+
+### Data Validation
+
+- Age validation prevents replay attacks
+- Size limits prevent DoS attacks
+- Content validation prevents malicious payloads
+
+## Troubleshooting
+
+### Policy Not Loading
+
+Check file permissions and path:
+
+```bash
+ls -la ~/.config/ORLY/policy.json
+cat ~/.config/ORLY/policy.json
+```
+
+### Scripts Not Working
+
+Verify script is executable and working:
+
+```bash
+ls -la /path/to/script.sh
+./path/to/script.sh < /dev/null
+```
+
+### Unexpected Behavior
+
+Enable debug logging:
+
+```bash
+export ORLY_LOG_LEVEL=debug
+```
+
+Check logs for policy decisions and errors.
+
+### Common Issues
+
+1. **Script timeouts**: Increase script timeouts or optimize script performance
+2. **Memory issues**: Reduce script memory usage or use built-in rules
+3. **Permission errors**: Fix file permissions on policy files and scripts
+4. **Configuration errors**: Validate JSON syntax and field names
+
+## Advanced Configuration
+
+### Multiple Policies
+
+Use different policies for different relay instances:
+
+```bash
+# Production relay
+export ORLY_APP_NAME=production
+# Policy at ~/.config/production/policy.json
+
+# Staging relay
+export ORLY_APP_NAME=staging
+# Policy at ~/.config/staging/policy.json
+```
+
+### Dynamic Policies
+
+Policies can be updated without restart by modifying the JSON file. Changes take effect immediately for new events.
+
+### Integration with External Systems
+
+Scripts can integrate with external services:
+
+```python
+import requests
+
+def check_external_service(content):
+    response = requests.post('http://moderation-service:8080/check',
+                           json={'content': content}, timeout=5)
+    return response.json().get('approved', False)
+```
+
+## Examples Repository
+
+See the `docs/` directory for complete examples:
+
+- `example-policy.json`: Complete policy configuration
+- `example-policy.sh`: Sample policy script
+- Various test scripts in `scripts/`
+
+## Support
+
+For issues with policy configuration:
+
+1. Check the logs for error messages
+2. Validate your JSON configuration
+3. Test scripts independently
+4. Review the examples in `docs/`
+5. Check file permissions and paths
+
+## Migration from Other Systems
+
+### From Simple Filtering
+
+Replace simple filters with policy rules:
+
+```json
+// Before: Simple size limit
+// After: Policy-based size limit
+{
+  "global": {
+    "size_limit": 50000
+  }
+}
+```
+
+### From Custom Code
+
+Migrate custom validation logic to policy scripts:
+
+```json
+{
+  "rules": {
+    "1": {
+      "script": "/etc/orly/scripts/custom-validation.py"
+    }
+  }
+}
+```
+
+The policy system provides a flexible, maintainable way to implement complex relay behavior while maintaining performance and security.

+
+Custom policy validation tools:
+
+```bash
+# Test policy with sample events
+./scripts/run-policy-test.sh
+
+# Test policy filter integration
+./scripts/run-policy-filter-test.sh
+```
+
+## Multi-Relay Testing Scenarios
+
+### Why Multiple Relays?
+
+Many Nostr protocol features require testing with multiple relays:
+
+- **Event replication** between relays
+- **Cross-relay subscriptions** and queries
+- **Relay discovery** and connection management
+- **Protocol interoperability** between different implementations
+- **Distributed features** like directory consensus
+
+### Testing Infrastructure
+
+ORLY provides several ways to run multiple relays for testing:
+
+#### 1. Local Multi-Relay Setup
+
+Run multiple instances on different ports:
+
+```bash
+# Terminal 1: Relay 1 on port 3334
+ORLY_PORT=3334 ./orly &
+
+# Terminal 2: Relay 2 on port 3335
+ORLY_PORT=3335 ./orly &
+
+# Terminal 3: Relay 3 on port 3336
+ORLY_PORT=3336 ./orly &
+```
+
+#### 2. Docker-based Multi-Relay
+
+Use Docker for isolated relay instances:
+
+```bash
+# Run multiple relays with Docker
+docker run -d -p 3334:3334 -e ORLY_PORT=3334 orly:latest
+docker run -d -p 3335:3334 -e ORLY_PORT=3334 orly:latest
+docker run -d -p 3336:3334 -e ORLY_PORT=3334 orly:latest
+```
+
+#### 3. Benchmark Suite Multi-Relay
+
+The benchmark suite automatically sets up multiple relays:
+
+```bash
+cd cmd/benchmark
+./setup-external-relays.sh
+docker-compose up next-orly khatru-sqlite strfry
+```
+
+## Developing Features Requiring Multiple Relays
+
+### 1. Event Replication Testing
+
+Test how events propagate between relays:
+
+```go
+// Example test for event replication
+func TestEventReplication(t *testing.T) {
+    // Start two relays
+    relay1 := startTestRelay(t, 3334)
+    defer relay1.Stop()
+
+    relay2 := startTestRelay(t, 3335)
+    defer relay2.Stop()
+
+    // Connect clients to both relays
+    client1 := connectToRelay(t, "ws://127.0.0.1:3334")
+    client2 := connectToRelay(t, "ws://127.0.0.1:3335")
+
+    // Publish event to relay1
+    event := createTestEvent(t)
+    ok := client1.Publish(event)
+    assert.True(t, ok)
+
+    // Wait for replication/propagation
+    time.Sleep(100 * time.Millisecond)
+
+    // Query relay2 for the event
+    events := client2.Query(filterForEvent(event.ID))
+    assert.Len(t, events, 1)
+    assert.Equal(t, event.ID, events[0].ID)
+}
+```
+
+### 2. Cross-Relay Subscriptions
+
+Test subscriptions that span multiple relays:
+
+```go
+func TestCrossRelaySubscriptions(t *testing.T) {
+    // Setup multiple relays
+    relays := setupMultipleRelays(t, 3)
+    defer stopRelays(t, relays)
+
+    clients := connectToRelays(t, relays)
+
+    // Subscribe to same filter on all relays
+    filter := Filter{Kinds: []int{1}, Limit: 10}
+
+    for _, client := range clients {
+        client.Subscribe(filter)
+    }
+
+    // Publish events to different relays
+    for i, client := range clients {
+        event := createTestEvent(t)
+        event.Content = fmt.Sprintf("Event from relay %d", i)
+        client.Publish(event)
+    }
+
+    // Verify events appear on all relays (if replication is enabled)
+    time.Sleep(200 * time.Millisecond)
+
+    for _, client := range clients {
+        events := client.GetReceivedEvents()
+        assert.GreaterOrEqual(t, len(events), 3) // At least the events from all relays
+    }
+}
+```
+
+### 3. Relay Discovery Testing
+
+Test relay list events and dynamic relay discovery:
+
+```go
+func TestRelayDiscovery(t *testing.T) {
+    relay1 := startTestRelay(t, 3334)
+    relay2 := startTestRelay(t, 3335)
+    defer relay1.Stop()
+    defer relay2.Stop()
+
+    client := connectToRelay(t, "ws://127.0.0.1:3334")
+
+    // Publish relay list event (kind 10002)
+    relayList := createRelayListEvent(t, []string{
+        "wss://relay1.example.com",
+        "wss://relay2.example.com",
+    })
+    client.Publish(relayList)
+
+    // Test that relay discovery works
+    discovered := client.QueryRelays()
+    assert.Contains(t, discovered, "wss://relay1.example.com")
+    assert.Contains(t, discovered, "wss://relay2.example.com")
+}
+```
+

+
+echo "Tests completed"
+```
+
+## Testing Distributed Features
+
+### Directory Consensus Testing
+
+Test NIP-XX directory consensus protocol:
+
+```go
+func TestDirectoryConsensus(t *testing.T) {
+    // Setup multiple relays with directory support
+    relays := setupDirectoryRelays(t, 5)
+    defer stopRelays(t, relays)
+
+    clients := connectToRelays(t, relays)
+
+    // Create trust acts between relays
+    for i, client := range clients {
+        trustAct := createTrustAct(t, client.Pubkey, relays[(i+1)%len(relays)].Pubkey, 80)
+        client.Publish(trustAct)
+    }
+
+    // Wait for consensus
+    time.Sleep(1 * time.Second)
+
+    // Verify trust relationships
+    for _, client := range clients {
+        trustGraph := client.QueryTrustGraph()
+        // Verify expected trust relationships exist
+        assert.True(t, len(trustGraph.GetAllTrustActs()) > 0)
+    }
+}
+```
+
+### Sync Protocol Testing
+
+Test event synchronization between relays:
+
+```go
+func TestRelaySynchronization(t *testing.T) {
+    relay1 := startTestRelay(t, 3334)
+    relay2 := startTestRelay(t, 3335)
+    defer relay1.Stop()
+    defer relay2.Stop()
+
+    // Enable sync between relays
+    configureSync(t, relay1, relay2)
+
+    client1 := connectToRelay(t, "ws://127.0.0.1:3334")
+    client2 := connectToRelay(t, "ws://127.0.0.1:3335")
+
+    // Publish events to relay1
+    events := createTestEvents(t, 100)
+    for _, event := range events {
+        client1.Publish(event)
+    }
+
+    // Wait for sync
+    waitForSync(t, relay1, relay2)
+
+    // Verify events on relay2
+    syncedEvents := client2.Query(Filter{Kinds: []int{1}, Limit: 200})
+    assert.Len(t, syncedEvents, 100)
+}
+```
+
+## Performance Testing with Multiple Relays
+
+### Load Testing
+
+Test performance under load with multiple relays:
+
+```bash
+# Start multiple relays
+for port in 3334 3335 3336; do
+    ORLY_PORT=$port ./orly &
+    echo $! >> relay_pids.txt
+done
+
+# Run load tests against each relay
+for port in 3334 3335 3336; do
+    echo "Testing relay on port $port"
+    relay-tester -url ws://127.0.0.1:$port -json > results_$port.json &
+done
+
+wait
+
+# Analyze results
+# Combine and compare performance across relays
+```
+
+### Benchmarking Comparisons
+
+Use the benchmark suite for comparative testing:
+
+```bash
+cd cmd/benchmark
+
+# Setup all relay types
+./setup-external-relays.sh
+
+# Run benchmarks comparing multiple implementations
+docker-compose up --build
+
+# Results in reports/run_YYYYMMDD_HHMMSS/
+cat reports/run_*/aggregate_report.txt
+```
+
+## Debugging Multi-Relay Issues
+
+### Logging
+
+Enable detailed logging for multi-relay debugging:
+
+```bash
+# Enable debug logging
+export ORLY_LOG_LEVEL=debug
+export ORLY_LOG_TO_STDOUT=true
+
+# Start relays with logging
+ORLY_PORT=3334 ./orly 2>&1 | tee relay1.log &
+ORLY_PORT=3335 ./orly 2>&1 | tee relay2.log &
+```
+
+### Connection Monitoring
+
+Monitor WebSocket connections between relays:
+
+```bash
+# Monitor network connections
+netstat -tlnp | grep :3334
+ss -tlnp | grep :3334
+
+# Monitor relay logs
+tail -f relay1.log | grep -E "(connect|disconnect|sync)"
+```
+
+### Event Tracing
+
+Trace events across multiple relays:
+
+```go
+func traceEventPropagation(t *testing.T, eventID string, relays []*TestRelay) {
+    for _, relay := range relays {
+        client := connectToRelay(t, relay.URL)
+        events := client.Query(Filter{IDs: []string{eventID}})
+        if len(events) > 0 {
+            t.Logf("Event %s found on relay %s", eventID, relay.URL)
+        } else {
+            t.Logf("Event %s NOT found on relay %s", eventID, relay.URL)
+        }
+    }
+}
+```
+

+
+## Best Practices
+
+### 1. Test Isolation
+
+- Use separate databases for each test relay
+- Clean up resources after tests
+- Use unique ports to avoid conflicts
+
+### 2. Timing Considerations
+
+- Allow time for event propagation between relays
+- Use exponential backoff for retry logic
+- Account for network latency in assertions
+
+### 3. Resource Management
+
+- Limit concurrent relays in CI/CD
+- Clean up Docker containers and processes
+- Monitor resource usage during tests
+
+### 4. Error Handling
+
+- Test both success and failure scenarios
+- Verify error propagation across relays
+- Test network failure scenarios
+
+### 5. Performance Monitoring
+
+- Measure latency between relays
+- Track memory and CPU usage
+- Monitor WebSocket connection stability
+
+## Troubleshooting Common Issues
+
+### Connection Failures
+
+```bash
+# Check if relays are listening
+netstat -tlnp | grep :3334
+
+# Test WebSocket connection manually
+websocat ws://127.0.0.1:3334
+```
+
+### Event Propagation Delays
+
+```bash
+# Increase wait times in tests
+time.Sleep(500 * time.Millisecond)
+
+// Or use polling
+func waitForEvent(t *testing.T, client *Client, eventID string) {
+    timeout := time.After(5 * time.Second)
+    ticker := time.NewTicker(100 * time.Millisecond)
+    defer ticker.Stop()
+
+    for {
+        select {
+        case <-timeout:
+            t.Fatalf("Event %s not found within timeout", eventID)
+        case <-ticker.C:
+            events := client.Query(Filter{IDs: []string{eventID}})
+            if len(events) > 0 {
+                return
+            }
+        }
+    }
+}
+```
+
+### Race Conditions
+
+```go
+// Use proper synchronization
+var mu sync.Mutex
+eventCount := 0
+
+// In test goroutines
+mu.Lock()
+eventCount++
+mu.Unlock()
+```
+
+### Resource Exhaustion
+
+```bash
+# Limit relay instances in tests
+const maxRelays = 3
+
+func setupLimitedRelays(t *testing.T, count int) []*TestRelay {
+    if count > maxRelays {
+        t.Skipf("Skipping test requiring %d relays (max %d)", count, maxRelays)
+    }
+    // Setup relays...
+}
+```
+

-# sha256-simd
-
-Accelerate SHA256 computations in pure Go using AVX512, SHA Extensions for x86
-and ARM64 for ARM.
-On AVX512 it provides an up to 8x improvement (over 3 GB/s per core).
-SHA Extensions give a performance boost of close to 4x over native.
-
-## Introduction
-
-This package is designed as a replacement for `crypto/sha256`.
-For ARM CPUs with the Cryptography Extensions, advantage is taken of the SHA2
-instructions resulting in a massive performance improvement.
-
-This package uses Golang assembly.
-The AVX512 version is based on the Intel's "multi-buffer crypto library for
-IPSec" whereas the other Intel implementations are described in "Fast SHA-256
-Implementations on Intel Architecture Processors" by J. Guilford et al.
-
-## Support for Intel SHA Extensions
-
-Support for the Intel SHA Extensions has been added by Kristofer Peterson (
-@svenski123), originally developed for
-spacemeshos [here](https://github.com/spacemeshos/POET/issues/23). On CPUs that
-support it (known thus far Intel Celeron J3455 and AMD Ryzen) it gives a
-significant boost in performance (with thanks to @AudriusButkevicius for
-reporting the results; full
-results [here](https://github.com/minio/sha256-simd/pull/37#issuecomment-451607827)).

-BenchmarkHash5M     514.40       1975.17       3.84x
-```
-
-Thanks to Kristofer Peterson, we also added additional performance changes such
-as optimized padding,
-endian conversions which sped up all implementations i.e. Intel SHA alone while
-doubled performance for small sizes,
-the other changes increased everything roughly 50%.
-
-## Support for AVX512
-
-We have added support for AVX512 which results in an up to 8x performance
-improvement over AVX2 (3.0 GHz Xeon Platinum 8124M CPU):
-
-```
-$ benchcmp avx2.txt avx512.txt

-BenchmarkHash5M     448.62       3498.20      7.80x
-```
-
-The original code was developed by Intel as part of
-the [multi-buffer crypto library](https://github.com/intel/intel-ipsec-mb) for
-IPSec or more specifically
-this [AVX512](https://github.com/intel/intel-ipsec-mb/blob/master/avx512/sha256_x16_avx512.asm)
-implementation. The key idea behind it is to process a total of 16 checksums in
-parallel by “transposing” 16 (independent) messages of 64 bytes between a total
-of 16 ZMM registers (each 64 bytes wide).
-
-Transposing the input messages means that in order to take full advantage of the
-speedup you need to have a (server) workload where multiple threads are doing
-SHA256 calculations in parallel. Unfortunately for this algorithm it is not
-possible for two message blocks processed in parallel to be dependent on one
-another — because then the (interim) result of the first part of the message has
-to be an input into the processing of the second part of the message.
-
-Whereas the original Intel C implementation requires some sort of explicit
-scheduling of messages to be processed in parallel, for Golang it makes sense to
-take advantage of channels in order to group messages together and use channels
-as well for sending back the results (thereby effectively decoupling the
-calculations). We have implemented a fairly simple scheduling mechanism that
-seems to work well in practice.
-
-Due to this different way of scheduling, we decided to use an explicit method to
-instantiate the AVX512 version. Essentially one or more AVX512 processing
-servers ([
-`Avx512Server`](https://github.com/minio/sha256-simd/blob/master/sha256blockAvx512_amd64.go#L294))
-have to be created whereby each server can hash over 3 GB/s on a single core. An
-`hash.Hash` object ([
-`Avx512Digest`](https://github.com/minio/sha256-simd/blob/master/sha256blockAvx512_amd64.go#L45))
-is then instantiated using one of these servers and used in the regular fashion:
-
-```go
-import "mleku.dev/pkg/sha256"
-
-func main() {
-	server := sha256.NewAvx512Server()
-	h512 := sha256.NewAvx512(server)
-	h512.Write(fileBlock)
-	digest := h512.Sum([]byte{})
-}
-```
-
-Note that, because of the scheduling overhead, for small messages (< 1 MB) you
-will be better off using the regular SHA256 hashing (but those are typically not
-performance critical anyway). Some other tips to get the best performance:
-
-- Have many go routines doing SHA256 calculations in parallel.
-- Try to Write() messages in multiples of 64 bytes.
-- Try to keep the overall length of messages to a roughly similar size ie. 5
-  MB (this way all 16 ‘lanes’ in the AVX512 computations are contributing as
-  much as possible).
-
-More detailed information can be found in
-this [blog](https://blog.minio.io/accelerate-sha256-up-to-8x-over-3-gb-s-per-core-with-avx512-a0b1d64f78f)
-post including scaling across cores.
-
-## Drop-In Replacement
-
-The following code snippet shows how you can use `github.com/minio/sha256-simd`.
-This will automatically select the fastest method for the architecture on which
-it will be executed.
-
-```go
-import "crypto.orly/sha256"
-
-func main() {
-        ...
-	shaWriter := sha256.New()
-	io.Copy(shaWriter, file)
-        ...
-}
-```
-
-## Performance
-
-Below is the speed in MB/s for a single core (ranked fast to slow) for blocks
-larger than 1 MB.
-
-| Processor                         | SIMD    | Speed (MB/s) |
-| --------------------------------- | ------- | -----------: |
-| 3.0 GHz Intel Xeon Platinum 8124M | AVX512  |         3498 |
-| 3.7 GHz AMD Ryzen 7 2700X         | SHA Ext |         1979 |
-| 1.2 GHz ARM Cortex-A53            | ARM64   |          638 |
-
-## asm2plan9s
-
-In order to be able to work more easily with AVX512/AVX2 instructions, a
-separate tool was developed to convert SIMD instructions into the corresponding
-BYTE sequence as accepted by Go assembly.
-See [asm2plan9s](https://github.com/minio/asm2plan9s) for more information.
-
-## Why and benefits
-
-One of the most performance sensitive parts of
-the [Minio](https://github.com/minio/minio) object storage server is related to
-SHA256 hash sums calculations. For instance during multi part uploads each part
-that is uploaded needs to be verified for data integrity by the server.
-
-Other applications that can benefit from enhanced SHA256 performance are
-deduplication in storage systems, intrusion detection, version control systems,
-integrity checking, etc.
-
-## ARM SHA Extensions
-
-The 64-bit ARMv8 core has introduced new instructions for SHA1 and SHA2
-acceleration as part of
-the [Cryptography Extensions](http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0501f/CHDFJBCJ.html).
-Below you can see a small excerpt highlighting one of the rounds as is done for
-the SHA256 calculation process (for full code
-see [sha256block_arm64.s](https://github.com/minio/sha256-simd/blob/master/sha256block_arm64.s)).

-## Methods
+### Payment Notifications
 
-- `get_info` - Get wallet info
-- `get_balance` - Get wallet balance
-- `make_invoice` - Create invoice
-- `lookup_invoice` - Check invoice status
-- `pay_invoice` - Pay invoice
-
-## Payment Notifications
+Subscribe to real-time payment notifications:
 
 ```go
 // Subscribe to payment notifications
 err = client.SubscribeNotifications(ctx, func(notificationType string, notification map[string]any) error {
-    if notificationType == "payment_received" {
+    switch notificationType {
+    case "payment_received":
         amount := notification["amount"].(float64)
+        paymentHash := notification["payment_hash"].(string)
         description := notification["description"].(string)
+        log.Printf("Payment received: %.2f sats for %s", amount/1000, description)
         // Process payment...
+
+    case "payment_sent":
+        amount := notification["amount"].(float64)
+        paymentHash := notification["payment_hash"].(string)
+        log.Printf("Payment sent: %.2f sats", amount/1000)
+        // Handle outgoing payment...
+
+    default:
+        log.Printf("Unknown notification type: %s", notificationType)
     }
     return nil
 })
 ```
 
-## Features
+## API Reference
 
+### Client Methods
+
+#### `NewClient(uri string) (*Client, error)`
+Creates a new NWC client from a connection URI.
+
+#### `Request(ctx context.Context, method string, params, result any) error`
+Makes a synchronous request to the wallet.
+
+#### `SubscribeNotifications(ctx context.Context, handler NotificationHandler) error`
+Subscribes to payment notifications with the provided handler function.
+
+#### `Close() error`
+Closes the client and cleans up resources.
+
+### Supported Methods
+
+| Method | Parameters | Description |
+|--------|------------|-------------|
+| `get_info` | None | Get wallet information and supported methods |
+| `get_balance` | None | Get current wallet balance |
+| `make_invoice` | `amount`, `description` | Create a new lightning invoice |
+| `lookup_invoice` | `payment_hash` | Check status of an existing invoice |
+| `pay_invoice` | `invoice` | Pay a lightning invoice |
+
+### Notification Types
+
+- `payment_received`: Incoming payment received
+- `payment_sent`: Outgoing payment sent
+- `invoice_paid`: Invoice was paid (alternative to payment_received)
+
+## Integration with ORLY
+
+The NWC client is integrated into the ORLY relay for payment processing:
+
+```bash
+# Enable NWC payments
+export ORLY_NWC_URI="nostr+walletconnect://..."
+
+# Start relay with payment support
+./orly
+```
+
+The relay will automatically:
+- Create invoices for premium features
+- Validate payments before granting access
+- Handle payment notifications
+- Update user balances
+
+## Error Handling
+
+The client provides comprehensive error handling:
+
+```go
+err = client.Request(ctx, "make_invoice", params, &result)
+if err != nil {
+    var nwcErr *nwc.Error
+    if errors.As(err, &nwcErr) {
+        switch nwcErr.Code {
+        case nwc.ErrInsufficientBalance:
+            // Handle insufficient funds
+        case nwc.ErrInvoiceExpired:
+            // Handle expired invoice
+        default:
+            // Handle other errors
+        }
+    }
+}
+```
+
+## Security Considerations
+
+- **URI Protection**: Keep NWC URIs secure and don't log them
+- **Context Timeouts**: Always use context with timeouts for requests
+- **Error Sanitization**: Don't expose internal wallet errors to users
+- **Rate Limiting**: Implement rate limiting to prevent abuse
+- **Audit Logging**: Log payment operations for audit purposes
+
+## Testing
+
+The NWC client includes comprehensive tests:
+
+### Running Tests
+
+```bash
+# Run NWC package tests
+go test ./pkg/protocol/nwc
+
+# Run with verbose output
+go test -v ./pkg/protocol/nwc
+
+# Run integration tests (requires wallet connection)
+go test -tags=integration ./pkg/protocol/nwc
+```
+
+### Integration Testing
+
+Part of the full test suite:
+
+```bash
+# Run all tests including NWC
+./scripts/test.sh
+
+# Run protocol package tests
+go test ./pkg/protocol/...
+```
+
+### Test Coverage
+
+Tests verify:
+- Client creation and connection
+- Request/response handling
+- Notification subscriptions
+- Error conditions and recovery
 - NIP-44 encryption
-- Event signing
-- Relay communication
-- Payment notifications
-- Error handling
+- Concurrent access patterns
+- Context cancellation
+
+### Mock Testing
+
+For testing without a real wallet:
+
+```go
+// Create mock client for testing
+mockClient := nwc.NewMockClient()
+mockClient.SetBalance(1000000) // 1000 sats
+
+// Use in tests
+result := make(map[string]any)
+err := mockClient.Request(ctx, "get_balance", nil, &result)
+```
+
+## Examples
+
+### Complete Payment Flow
+
+```go
+package main
+
+import (
+    "context"
+    "log"
+    "time"
+
+    "next.orly.dev/pkg/protocol/nwc"
+)
+
+func main() {

+
+    // Get wallet info
+    var info map[string]any
+    if err := client.Request(ctx, "get_info", nil, &info); err != nil {

+
+    // Create invoice

+    }
+
+    bolt11 := invoice["invoice"].(string)
+    log.Printf("Created invoice: %s", bolt11)
+
+    // In a real application, you would present this invoice to the user
+    // For testing, you can pay it using the same client
+    payParams := map[string]any{"invoice": bolt11}
+    var payment map[string]any
+    if err := client.Request(ctx, "pay_invoice", payParams, &payment); err != nil {
+        log.Printf("Failed to pay invoice: %v", err)
+        return
+    }
+
+    log.Printf("Payment successful: %v", payment)
+}
+```
+
+### Notification Handler
+
+```go
+func setupPaymentHandler(client *nwc.Client) {
+    ctx := context.Background()
+
+    err := client.SubscribeNotifications(ctx, func(notificationType string, notification map[string]any) error {
+        log.Printf("Received notification: %s", notificationType)
+
+        switch notificationType {
+        case "payment_received":
+            // Grant access to paid feature
+            userID := notification["description"].(string)
+            amount := notification["amount"].(float64)
+            grantPremiumAccess(userID, amount)
+
+        case "payment_sent":
+            // Log outgoing payment
+            amount := notification["amount"].(float64)
+            log.Printf("Outgoing payment: %.2f sats", amount/1000)
+
+        default:
+            log.Printf("Unknown notification type: %s", notificationType)
+        }
+
+        return nil
+    })
+
+    if err != nil {
+        log.Printf("Failed to subscribe to notifications: %v", err)
+    }
+}
+```
+

 # atomic
 
-Simple wrappers for primitive types to enforce atomic access.
+Type-safe atomic operations for Go primitive types. This package provides convenient wrappers around Go's `sync/atomic` package to ensure safe concurrent access to shared variables.
+
+## Features
+
+- **Type Safety**: Strongly typed wrappers prevent accidental misuse
+- **Memory Safety**: Prevents race conditions in concurrent programs
+- **Performance**: Zero-overhead wrappers around standard library atomics
+- **Comprehensive Coverage**: Supports all common primitive types
+- **Thread Safe**: All operations are atomic and safe for concurrent access
 
 ## Installation
 
-```shell
-$ go get -u github.com/mleku/nodl/pkg/atomic@latest
+```bash
+go get next.orly.dev/pkg/utils/atomic
 ```
 
 ## Usage
 
-The standard library's `sync/atomic` is powerful, but it's easy to forget which
-variables must be accessed atomically. `github.com/mleku/nodl/pkg/atomic` preserves all the
-functionality of the standard library, but wraps the primitive types to
-provide a safer, more convenient API.
+The atomic package provides type-safe wrappers around Go's standard `sync/atomic` operations:
+
+### Basic Operations
 
 ```go
-var atom atomic.Uint32
-atom.Store(42)
-atom.Sub(2)
-atom.CompareAndSwap(40, 11)
+import "next.orly.dev/pkg/utils/atomic"
+
+// Integer types
+var counter atomic.Uint64
+counter.Store(42)
+value := counter.Load()  // 42
+counter.Add(8)          // 50
+
+// Boolean operations
+var flag atomic.Bool
+flag.Store(true)
+if flag.Load() {
+    // Handle true case
+}
+
+// Pointer operations
+var ptr atomic.Pointer[string]
+ptr.Store(&someString)
+loadedPtr := ptr.Load()
 ```
 
-See the [documentation][doc] for a complete API specification.
+### Advanced Operations
 
-## Development Status
+```go
+// Compare and swap
+var value atomic.Int64
+value.Store(100)
+swapped := value.CompareAndSwap(100, 200)  // true, value is now 200
 
-Stable.
+// Swap operations
+oldValue := value.Swap(300)  // oldValue = 200, new value = 300
 
----
+// Atomic add/subtract
+delta := value.Add(50)  // Add 50, return new value (350)
+value.Sub(25)           // Subtract 25, value is now 325
+```
 
-Released under the [MIT License](LICENSE.txt).
+### Supported Types
+
+| Type | Description |
+|------|-------------|
+| `Bool` | Atomic boolean operations |
+| `Int32` | 32-bit signed integer |
+| `Int64` | 64-bit signed integer |
+| `Uint32` | 32-bit unsigned integer |
+| `Uint64` | 64-bit unsigned integer |
+| `Uintptr` | Pointer-sized unsigned integer |
+| `Float64` | 64-bit floating point |
+| `Pointer[T]` | Generic pointer type |
+
+### Generic Pointer Example
+
+```go
+// Type-safe pointer operations
+var config atomic.Pointer[Config]
+config.Store(&myConfig)
+
+// Load with type safety
+currentConfig := config.Load()
+if currentConfig != nil {
+    // Use config with full type safety
+}
+```
+
+## API Reference
+
+All atomic types implement a consistent interface:
+
+- `Load() T` - Atomically load the current value
+- `Store(val T)` - Atomically store a new value
+- `Swap(new T) T` - Atomically swap values, return old value
+- `CompareAndSwap(old, new T) bool` - CAS operation
+
+Additional methods by type:
+
+**Integer Types (Int32, Int64, Uint32, Uint64):**
+- `Add(delta T) T` - Atomically add delta, return new value
+- `Sub(delta T) T` - Atomically subtract delta, return new value
+
+**Float64:**
+- `Add(delta float64) float64` - Atomically add delta
+
+## Testing
+
+The atomic package includes comprehensive tests:
+
+### Running Tests

 # interrupt
 
-Handle shutdowns cleanly and enable hot reload
+Graceful shutdown handling for Go applications. This package provides utilities for handling OS signals (SIGINT, SIGTERM) to enable clean shutdowns and hot reloading capabilities.
+
+## Features
+
+- **Signal Handling**: Clean handling of SIGINT, SIGTERM, and SIGHUP signals
+- **Graceful Shutdown**: Allows running goroutines to finish before exit
+- **Hot Reload Support**: Trigger application reloads on SIGHUP
+- **Context Integration**: Works seamlessly with Go's context package
+- **Custom Callbacks**: Execute custom cleanup logic during shutdown
+- **Non-blocking**: Doesn't block the main application loop
+
+## Installation
+
+```bash
+go get next.orly.dev/pkg/utils/interrupt
+```
+
+## Usage
+
+### Basic Shutdown Handling
+
+```go
+package main
+
+import (
+    "context"
+    "log"
+    "time"
+
+    "next.orly.dev/pkg/utils/interrupt"
+)
+
+func main() {
+    // Create interrupt handler
+    handler := interrupt.New()
+
+    // Start your application
+    go func() {
+        for {
+            select {
+            case <-handler.Shutdown():
+                log.Println("Shutting down worker...")
+                return
+            default:
+                // Do work
+                time.Sleep(time.Second)
+            }
+        }
+    }()
+
+    // Wait for shutdown signal
+    <-handler.Done()
+    log.Println("Application stopped")
+}
+```
+
+### Context Integration
+
+```go
+func worker(ctx context.Context) {
+    handler := interrupt.New()
+
+    // Create context that cancels on shutdown
+    workCtx, cancel := context.WithCancel(ctx)
+    defer cancel()
+
+    go func() {
+        <-handler.Shutdown()
+        cancel()
+    }()
+
+    // Use workCtx for all operations
+    for {
+        select {
+        case <-workCtx.Done():
+            return
+        default:
+            // Do work with context
+        }
+    }
+}
+```
+
+### Custom Shutdown Callbacks
+
+```go
+handler := interrupt.New()
+
+// Add cleanup callbacks
+handler.OnShutdown(func() {
+    log.Println("Closing database connections...")
+    db.Close()
+})
+
+handler.OnShutdown(func() {
+    log.Println("Saving application state...")
+    saveState()
+})
+
+// Callbacks execute in reverse order when shutdown occurs
+<-handler.Done()
+```
+
+### Hot Reload Support
+
+```go
+handler := interrupt.New()
+
+// Handle reload signals
+go func() {
+    for {
+        select {
+        case <-handler.Reload():
+            log.Println("Reloading configuration...")
+            reloadConfig()
+        case <-handler.Shutdown():
+            return
+        }
+    }
+}()
+
+<-handler.Done()
+```
+
+## API Reference
+
+### Handler
+
+The main interrupt handler type.
+
+**Methods:**
+- `New() *Handler` - Create a new interrupt handler
+- `Shutdown() <-chan struct{}` - Channel closed on shutdown signals
+- `Reload() <-chan struct{}` - Channel closed on reload signals (SIGHUP)
+- `Done() <-chan struct{}` - Channel closed when all cleanup is complete
+- `OnShutdown(func())` - Add a callback to run during shutdown
+- `Wait()` - Block until shutdown signal received
+- `IsShuttingDown() bool` - Check if shutdown is in progress
+
+### Signal Handling
+
+The package handles these signals:
+
+- **SIGINT**: Interrupt (Ctrl+C) - Triggers graceful shutdown
+- **SIGTERM**: Termination - Triggers graceful shutdown
+- **SIGHUP**: Hangup - Triggers reload (can be customized)
+
+### Shutdown Process
+
+1. Signal received (SIGINT/SIGTERM)
+2. Shutdown callbacks execute (in reverse order added)
+3. Shutdown channel closes
+4. Application can perform final cleanup
+5. Done channel closes
+
+## Testing
+
+The interrupt package includes comprehensive tests:
+
+### Running Tests

+The web UI is embedded in the relay binary and accessible at the relay's root path. For development with hot-reloading:
 
 [source,bash]
 ----
-# Enable development proxy
 export ORLY_WEB_DISABLE_EMBEDDED=true
 export ORLY_WEB_DEV_PROXY_URL=localhost:5000
-
-# Start relay
-./orly
-
-# In another terminal, start Svelte dev server
-cd app/web
-bun run dev
+./orly &
+cd app/web && bun run dev
 ----
 
-This allows for rapid development with automatic reloading of changes.
+=== sprocket event processing
 
-== sprocket event sifter interface
+ORLY includes a powerful sprocket system for external event processing scripts. Sprocket scripts enable custom filtering, validation, and processing logic for Nostr events before storage.
 
-The sprocket system provides a powerful interface for external event processing scripts, allowing you to implement custom filtering, validation, and processing logic for Nostr events before they are stored in the relay.
-
-=== overview
-
-Sprocket scripts receive events via stdin and respond with JSONL (JSON Lines) format, enabling real-time event processing with three possible actions:
-
-* **accept**: Continue with normal event processing
-* **reject**: Return OK false to client with rejection message
-* **shadowReject**: Return OK true to client but abort processing (useful for spam filtering)
-
-=== how it works
-
-1. **Event Reception**: Events are sent to the sprocket script as JSON objects via stdin
-2. **Processing**: Script analyzes the event and applies custom logic
-3. **Response**: Script responds with JSONL containing the decision and optional message
-4. **Action**: Relay processes the response and either accepts, rejects, or shadow rejects the event
-
-=== script protocol
-
-==== input format
-
-Events are sent as JSON objects, one per line:
-
-```json
-{
-  "id": "event_id_here",

-```
-
-==== output format
-
-Scripts must respond with JSONL format:
-
-```json
-{"id": "event_id", "action": "accept", "msg": ""}
-{"id": "event_id", "action": "reject", "msg": "reason for rejection"}
-{"id": "event_id", "action": "shadowReject", "msg": ""}
-```
-
-=== configuration
-
-Enable sprocket processing:
+* **Real-time Processing**: Scripts receive events via stdin and respond with JSONL decisions
+* **Three Actions**: `accept`, `reject`, or `shadowReject` events based on custom logic
+* **Automatic Recovery**: Failed scripts are automatically disabled with periodic recovery attempts
+* **Web UI Management**: Upload, configure, and monitor scripts through the admin interface
 
 [source,bash]
 ----
 export ORLY_SPROCKET_ENABLED=true
 export ORLY_APP_NAME="ORLY"
+# Place script at ~/.config/ORLY/sprocket.sh
 ----
 
-The sprocket script should be placed at:
-`~/.config/{ORLY_APP_NAME}/sprocket.sh`
+For detailed configuration and examples, see the link:docs/sprocket/[sprocket documentation].
 
-For example, with default `ORLY_APP_NAME="ORLY"`:
-`~/.config/ORLY/sprocket.sh`
+=== policy system
 
-Backup files are automatically created when updating sprocket scripts via the web UI, with timestamps like:
-`~/.config/ORLY/sprocket.sh.20240101120000`
+ORLY includes a comprehensive policy system for fine-grained control over event storage and retrieval. Configure custom validation rules, access controls, size limits, and age restrictions.
 
-=== manual sprocket updates
-
-For manual sprocket script updates, you can use the stop/write/restart method:
-
-1. **Stop the relay**:
-   ```bash
-   # Send SIGINT to gracefully stop
-   kill -INT <relay_pid>
-   ```
-
-2. **Write new sprocket script**:
-   ```bash
-   # Create/update the sprocket script
-   cat > ~/.config/ORLY/sprocket.sh << 'EOF'
-   #!/bin/bash
-   while read -r line; do
-       if [[ -n "$line" ]]; then
-           event_id=$(echo "$line" | jq -r '.id')
-           echo "{\"id\":\"$event_id\",\"action\":\"accept\",\"msg\":\"\"}"
-       fi
-   done
-   EOF
-   
-   # Make it executable
-   chmod +x ~/.config/ORLY/sprocket.sh
-   ```
-
-3. **Restart the relay**:
-   ```bash
-   ./orly
-   ```
-
-The relay will automatically detect the new sprocket script and start it. If the script fails, sprocket will be disabled and all events rejected until the script is fixed.
-
-=== failure handling
-
-When sprocket is enabled but fails to start or crashes:
-
-1. **Automatic Disable**: Sprocket is automatically disabled
-2. **Event Rejection**: All incoming events are rejected with error message
-3. **Periodic Recovery**: Every 30 seconds, the system checks if the sprocket script becomes available
-4. **Auto-Restart**: If the script is found, sprocket is automatically re-enabled and restarted
-
-This ensures that:
-- Relay continues running even when sprocket fails
-- No events are processed without proper sprocket filtering
-- Sprocket automatically recovers when the script is fixed
-- Clear error messages inform users about the sprocket status
-- Error messages include the exact file location for easy fixes
-
-When sprocket fails, the error message will show:
-`sprocket disabled due to failure - all events will be rejected (script location: ~/.config/ORLY/sprocket.sh)`
-
-This makes it easy to locate and fix the sprocket script file.
-
-=== example script
-
-Here's a Python example that implements various filtering criteria:
-
-[source,python]
-----
-#!/usr/bin/env python3
-import json
-import sys
-
-def process_event(event_json):
-    event_id = event_json.get('id', '')
-    event_content = event_json.get('content', '')
-    event_kind = event_json.get('kind', 0)
-    
-    # Reject spam content
-    if 'spam' in event_content.lower():
-        return {
-            'id': event_id,
-            'action': 'reject',
-            'msg': 'Content contains spam'
-        }
-    
-    # Shadow reject test events
-    if event_kind == 9999:
-        return {
-            'id': event_id,
-            'action': 'shadowReject',
-            'msg': ''
-        }
-    
-    # Accept all other events
-    return {
-        'id': event_id,
-        'action': 'accept',
-        'msg': ''
-    }
-
-# Main processing loop
-for line in sys.stdin:
-    if line.strip():
-        try:
-            event = json.loads(line)
-            response = process_event(event)
-            print(json.dumps(response))
-            sys.stdout.flush()
-        except json.JSONDecodeError:
-            continue
-----
-
-=== bash example
-
-A simple bash script example:
+* **Access Control**: Allow/deny based on pubkeys, roles, or social relationships
+* **Content Filtering**: Size limits, age validation, and custom rules
+* **Script Integration**: Execute custom scripts for complex policy logic
+* **Real-time Enforcement**: Policies applied to both read and write operations
 
 [source,bash]
 ----
-#!/bin/bash
-while read -r line; do
-    if [[ -n "$line" ]]; then
-        # Extract event ID
-        event_id=$(echo "$line" | jq -r '.id')
-        
-        # Check for spam content

-    fi
-done
+export ORLY_POLICY_ENABLED=true
+# Create policy file at ~/.config/ORLY/policy.json
 ----
 
-=== testing
-
-Test your sprocket script directly:
-
-[source,bash]
-----
-# Test with sample event
-echo '{"id":"test","kind":1,"content":"spam test"}' | python3 sprocket.py
-
-# Expected output:
-# {"id": "test", "action": "reject", "msg": "Content contains spam"}
-----
-
-Run the comprehensive test suite:
-
-[source,bash]
-----
-./test-sprocket-complete.sh
-----
-
-=== web UI management
-
-The web UI provides a complete sprocket management interface:
-
-* **Status Monitoring**: View real-time sprocket status and health
-* **Script Upload**: Upload new sprocket scripts via the web interface
-* **Version Management**: Track and manage multiple script versions
-* **Configuration**: Configure sprocket parameters and settings
-* **Logs**: View execution logs and error messages
-* **Restart**: Restart sprocket scripts without relay restart
-
-=== use cases
-
-Common sprocket use cases include:
-
-* **Spam Filtering**: Detect and reject spam content
-* **Content Moderation**: Implement custom content policies
-* **Rate Limiting**: Control event publishing rates
-* **Event Validation**: Additional validation beyond Nostr protocol
-* **Analytics**: Log and analyze event patterns
-* **Integration**: Connect with external services and APIs
-
-=== performance considerations
-
-* Sprocket scripts run synchronously and can impact relay performance
-* Keep processing logic efficient and fast
-* Use appropriate timeouts to prevent blocking
-* Consider using shadow reject for non-critical filtering to maintain user experience
-
-== secp256k1 dependency
-
-ORLY uses the optimized `libsecp256k1` C library from Bitcoin Core for schnorr signatures, providing 4x faster signing and ECDH operations compared to pure Go implementations.
-
-=== installation
-
-For Ubuntu/Debian, you can use the provided installation script:
-
-[source,bash]
-----
-./scripts/ubuntu_install_libsecp256k1.sh
-----
-
-Or install manually:
-
-[source,bash]
-----
-# Install build dependencies
-sudo apt -y install build-essential autoconf libtool
-
-# Initialize and build secp256k1
-cd pkg/crypto/p256k/secp256k1
-git submodule init
-git submodule update
-./autogen.sh
-./configure --enable-module-schnorrsig --enable-module-ecdh --prefix=/usr
-make
-sudo make install
-----
-
-=== fallback mode
-
-If you need to build without the C library dependency, disable CGO:
-
-[source,bash]
-----
-export CGO_ENABLED=0
-go build -o orly
-----
-
-This uses the pure Go `btcec` fallback library, which is slower but doesn't require system dependencies.
+For detailed configuration and examples, see the link:docs/POLICY_USAGE_GUIDE.md[Policy Usage Guide].

-
-== benchmarks
-
-The benchmark suite provides comprehensive performance testing and comparison across multiple relay implementations.
-
-=== quick start
-
-1. **Setup external relays:**
-+
-[source,bash]
-----
-cd cmd/benchmark
-./setup-external-relays.sh
-----
-
-2. **Run all benchmarks:**
-+
-[source,bash]
-----
-docker compose up --build
-----
-
-3. **View results:**
-+
-[source,bash]
-----
-# View aggregate report
-cat reports/run_YYYYMMDD_HHMMSS/aggregate_report.txt
-
-# List individual relay results
-ls reports/run_YYYYMMDD_HHMMSS/
-----
-
-=== benchmark types
-
-The suite includes three main benchmark patterns:
-
-==== peak throughput test
-Tests maximum event ingestion rate with concurrent workers pushing events as fast as possible. Measures events/second, latency distribution, and success rate.
-
-==== burst pattern test  
-Simulates real-world traffic with alternating high-activity bursts and quiet periods to test relay behavior under varying loads.
-
-==== mixed read/write test
-Concurrent read and write operations to test query performance while events are being ingested. Measures combined throughput and latency.
-
-=== tested relays
-
-The benchmark suite compares:
-
-* **next.orly.dev** (this repository) - BadgerDB-based relay
-* **Khatru** - SQLite and Badger variants  
-* **Relayer** - Basic example implementation
-* **Strfry** - C++ LMDB-based relay
-* **nostr-rs-relay** - Rust-based relay with SQLite
-
-=== metrics reported
-
-* **Throughput**: Events processed per second
-* **Latency**: Average, P95, and P99 response times  
-* **Success Rate**: Percentage of successful operations
-* **Memory Usage**: Peak memory consumption during tests
-* **Error Analysis**: Detailed error reporting and categorization
-
-Results are timestamped and stored in the `reports/` directory for tracking performance improvements over time.
-
-== follows ACL
-
-The follows ACL (Access Control List) system provides a flexible way to control relay access based on social relationships in the Nostr network. It grants different access levels to users based on whether they are followed by designated admin users.
-
-=== how it works
-
-The follows ACL system operates by:
-
-1. **Admin Configuration**: Designated admin users are specified in the relay configuration
-2. **Follow List Discovery**: The system fetches follow lists (kind 3 events) from admin users
-3. **Access Level Assignment**:
-   - **Admin access**: Users listed as admins get full administrative privileges
-   - **Write access**: Users followed by any admin can publish events to the relay
-   - **Read access**: All other users can only read events from the relay
-
-=== configuration
-
-Enable the follows ACL system by setting the ACL mode:
-
-[source,bash]
-----
-export ORLY_ACL_MODE=follows
-export ORLY_ADMINS=npub1abc...,npub1xyz...
-----
-
-Or in your environment configuration:
-
-[source,env]
-----
-ORLY_ACL_MODE=follows
-ORLY_ADMINS=npub1abc123...,npub1xyz456...
-----
-
-=== usage example
-
-[source,bash]
-----
-# Set up a relay with follows ACL
 export ORLY_ACL_MODE=follows
 export ORLY_ADMINS=npub1fjqqy4a93z5zsjwsfxqhc2764kvykfdyttvldkkkdera8dr78vhsmmleku
-
-# Start the relay
 ./orly
 ----
 
-The relay will automatically:
-- Load the follow lists of the specified admin users
-- Grant write access to anyone followed by these admins
-- Provide read-only access to everyone else
-- Update follow lists dynamically as admins modify their follows
+The system grants write access to users followed by designated admins, with read-only access for others. Follow lists update dynamically as admins modify their relationships.
+
+=== cluster replication
+
+ORLY supports distributed relay clusters using active replication. When configured with peer relays, ORLY will automatically synchronize events between cluster members using efficient HTTP polling.
+
+[source,bash]
+----
+export ORLY_RELAY_PEERS=https://peer1.example.com,https://peer2.example.com
+export ORLY_CLUSTER_ADMINS=npub1cluster_admin_key
+----
+
+**Privacy Considerations:** By default, ORLY propagates all events including privileged events (DMs, gift wraps, etc.) to cluster peers for complete synchronization. This ensures no data loss but may expose private communications to other relay operators in your cluster.
+
+To enhance privacy, you can disable propagation of privileged events:
+
+[source,bash]
+----
+export ORLY_CLUSTER_PROPAGATE_PRIVILEGED_EVENTS=false
+----
+
+**Important:** When disabled, privileged events will not be replicated to peer relays. This provides better privacy but means these events will only be available on the originating relay. Users should be aware that accessing their privileged events may require connecting directly to the relay where they were originally published.
