-# Implementation Plan: Enhanced Admin Event API Structure
-
-## Current Issue
-
-The current admin event routing at [`main.c:3248-3268`](src/main.c:3248) has a security vulnerability:
-
-```c
-if (event_kind == 23455 || event_kind == 23456) {
-    // Admin event processing
-    int admin_result = process_admin_event_in_config(event, admin_error, sizeof(admin_error), wsi);
-} else {
-    // Regular event storage and broadcasting
-}
-```
-
-**Problem**: Any event with these kinds gets routed to admin processing, regardless of authorization. This allows unauthorized users to send admin events that could be processed as legitimate admin commands.
-
-**Note**: Event kinds 33334 and 33335 are no longer used and have been removed from the admin event routing.
-
-## Required Security Enhancement
-
-Admin events must be validated for proper authorization BEFORE routing to admin processing:
-
-1. **Relay Public Key Check**: Event must have a `p` tag equal to the relay's public key
-2. **Admin Signature Check**: Event must be signed by an authorized admin private key
-3. **Fallback to Regular Processing**: If authorization fails, treat as regular event (not admin event)
-
-## Implementation Plan
-
-### Phase 1: Add Admin Authorization Validation
-
-#### 1.1 Create Consolidated Admin Authorization Function
-**Location**: [`src/main.c`](src/main.c) or [`src/config.c`](src/config.c)
-
-```c
-/**
- * Consolidated admin event authorization validator
- * Implements defense-in-depth security for admin events
- *
- * @param event - The event to validate for admin authorization
- * @param error_message - Buffer for detailed error messages
- * @param error_size - Size of error message buffer
- * @return 0 if authorized, -1 if unauthorized, -2 if validation error

-#### 1.2 Update Event Routing Logic
-**Location**: [`main.c:3248`](src/main.c:3248)
-
-```c
-// Current problematic code:
-if (event_kind == 23455 || event_kind == 23456) {

-        
-        // Check if this is an admin event
-        if (event_kind == 23455 || event_kind == 23456) {

-                int admin_result = process_admin_event_in_config(event, admin_error, sizeof(admin_error), wsi);
-                
-                if (admin_result != 0) {

-                }
-                // Admin events are NOT broadcast to subscriptions

-            }
-        }
-    }
-}
-```
-
-### Phase 2: Enhanced Admin Event Processing
-
-#### 2.1 Admin Event Validation in Config System
-**Location**: [`src/config.c`](src/config.c) - [`process_admin_event_in_config()`](src/config.c:2065)
-
-Add additional validation within the admin processing function:
-
-```c
-int process_admin_event_in_config(cJSON* event, char* error_buffer, size_t error_buffer_size, struct lws* wsi) {
-    // Double-check authorization (defense in depth)
-    if (!is_authorized_admin_event(event)) {
-        snprintf(error_buffer, error_buffer_size, "unauthorized: not a valid admin event");
-        return -1;
-    }
-    
-    // Continue with existing admin event processing...
-    // ... rest of function unchanged
-}
-```
-
-#### 2.2 Logging and Monitoring
-Add comprehensive logging for admin event attempts:
-
-```c
-// In the routing logic - enhanced logging
-cJSON* kind_obj = cJSON_GetObjectItem(event, "kind");
-cJSON* pubkey_obj = cJSON_GetObjectItem(event, "pubkey");
-int event_kind = kind_obj ? cJSON_GetNumberValue(kind_obj) : -1;
-const char* event_pubkey = pubkey_obj ? cJSON_GetStringValue(pubkey_obj) : "unknown";
-
-if (is_authorized_admin_event(event)) {
-    char log_msg[256];
-    snprintf(log_msg, sizeof(log_msg),
-            "ADMIN EVENT: Authorized admin event (kind=%d) from pubkey=%.16s...",
-            event_kind, event_pubkey);
-    log_info(log_msg);
-} else if (event_kind == 23455 || event_kind == 23456) {
-    // This catches unauthorized admin event attempts
-    char log_msg[256];
-    snprintf(log_msg, sizeof(log_msg),
-            "SECURITY: Unauthorized admin event attempt (kind=%d) from pubkey=%.16s...",
-            event_kind, event_pubkey);
-    log_warning(log_msg);
-}
-```
-
-## Phase 3: Unified Output Flow Architecture
-
-### 3.1 Current Output Flow Analysis
-
-After analyzing both [`main.c`](src/main.c) and [`config.c`](src/config.c), the **admin event responses already flow through the standard WebSocket output pipeline**. This is the correct architecture and requires no changes.
-
-#### Standard WebSocket Output Pipeline
-
-**Regular Events** ([`main.c:2978-2996`](src/main.c:2978)):
-```c
-// Database query responses
-unsigned char* buf = malloc(LWS_PRE + msg_len);
-memcpy(buf + LWS_PRE, msg_str, msg_len);
-lws_write(wsi, buf + LWS_PRE, msg_len, LWS_WRITE_TEXT);
-free(buf);
-```
-
-**OK Responses** ([`main.c:3342-3375`](src/main.c:3342)):
-```c
-// Event processing results: ["OK", event_id, success_boolean, message]
-unsigned char *buf = malloc(LWS_PRE + response_len);
-memcpy(buf + LWS_PRE, response_str, response_len);
-lws_write(wsi, buf + LWS_PRE, response_len, LWS_WRITE_TEXT);
-free(buf);
-```
-
-#### Admin Event Output Pipeline (Already Unified)
-
-**Admin Responses** ([`config.c:2363-2414`](src/config.c:2363)):
-```c
-// Admin query responses use IDENTICAL pattern
-int send_websocket_response_data(struct lws* wsi, cJSON* response_data) {
-    unsigned char* buf = malloc(LWS_PRE + response_len);
-    memcpy(buf + LWS_PRE, response_str, response_len);
-    
-    // Same lws_write() call as regular events
-    int result = lws_write(wsi, buf + LWS_PRE, response_len, LWS_WRITE_TEXT);
-    
-    free(buf);
-    return result;
-}
-```
-
-### 3.2 Unified Output Flow Confirmation
-
-✅ **Admin responses already use the same WebSocket transmission mechanism as regular events**
-
-✅ **Both admin and regular events use identical buffer allocation patterns**
-
-✅ **Both admin and regular events use the same [`lws_write()`](src/config.c:2393) function**
-
-✅ **Both admin and regular events follow the same cleanup patterns**
-
-### 3.3 Output Flow Integration Points
-
-The admin event processing in [`config.c:2436`](src/config.c:2436) already integrates correctly with the unified output system:
-
-1. **Admin Query Processing** ([`config.c:2568-2583`](src/config.c:2568)):
-   - Auth queries return structured JSON via [`send_websocket_response_data()`](src/config.c:2571)
-   - System commands return status data via [`send_websocket_response_data()`](src/config.c:2631)
-
-2. **Response Format Consistency**:
-   - Admin responses use standard JSON format
-   - Regular events use standard Nostr event format
-   - Both transmitted through same WebSocket pipeline
-
-3. **Error Handling Consistency**:
-   - Admin errors returned via same WebSocket connection
-   - Regular event errors returned via OK messages
-   - Both use identical transmission mechanism
-
-### 3.4 Key Architectural Benefits
-
-**No Changes Required**: The output flow is already unified and correctly implemented.
-
-**Security Separation**: Admin events are processed separately but responses flow through the same secure WebSocket channel.
-
-**Performance Consistency**: Both admin and regular responses use the same optimized transmission path.
-
-**Maintenance Simplicity**: Single WebSocket output pipeline reduces complexity and potential bugs.
-
-### 3.5 Admin Event Flow Summary
-
-```
-Admin Event Input → Authorization Check → Admin Processing → Unified WebSocket Output
-Regular Event Input → Validation → Storage + Broadcast → Unified WebSocket Output
-```
-
-Both flows converge at the **Unified WebSocket Output** stage, which is already correctly implemented.
-
-## Phase 4: Integration Points for Secure Admin Event Routing
-
-### 4.1 Configuration System Integration
-
-**Required Configuration Values**:
-- `admin_pubkey` - Public key of authorized administrator
-- `relay_pubkey` - Public key of this relay instance
-
-**Integration Points**:
-1. [`get_config_value()`](src/config.c) - Used by authorization function
-2. [`get_relay_pubkey_cached()`](src/config.c) - Used for relay targeting validation
-3. Configuration loading during startup - Must ensure admin/relay pubkeys are available
-
-### 4.3 Forward Declarations Required
-
-**Location**: [`src/main.c`](src/main.c) - Add near other forward declarations (around line 230)
-
-```c
-// Forward declarations for enhanced admin event authorization
-int is_authorized_admin_event(cJSON* event, char* error_message, size_t error_size);
-```
-
-### 4.4 Error Handling Integration
-
-**Enhanced Error Response System**:
-
-```c
-// In main.c event processing - enhanced error handling for admin events
-if (auth_result != 0) {
-    // Admin authorization failed - send detailed OK response
-    cJSON* event_id = cJSON_GetObjectItem(event, "id");
-    if (event_id && cJSON_IsString(event_id)) {
-        cJSON* response = cJSON_CreateArray();
-        cJSON_AddItemToArray(response, cJSON_CreateString("OK"));
-        cJSON_AddItemToArray(response, cJSON_CreateString(cJSON_GetStringValue(event_id)));
-        cJSON_AddItemToArray(response, cJSON_CreateBool(0)); // Failed
-        cJSON_AddItemToArray(response, cJSON_CreateString(auth_error));
-        
-        // Send via standard WebSocket output pipeline
-        char *response_str = cJSON_Print(response);
-        if (response_str) {
-            size_t response_len = strlen(response_str);
-            unsigned char *buf = malloc(LWS_PRE + response_len);
-            if (buf) {
-                memcpy(buf + LWS_PRE, response_str, response_len);
-                lws_write(wsi, buf + LWS_PRE, response_len, LWS_WRITE_TEXT);
-                free(buf);
-            }
-            free(response_str);
-        }
-        cJSON_Delete(response);
-    }
-}
-```
-
-### 4.5 Logging Integration Points
-
-**Console Logging**: Uses existing [`log_warning()`](src/main.c:993), [`log_info()`](src/main.c:972) functions
-
-**Security Event Categories**:
-- Admin authorization success logged via `log_info()`
-- Admin authorization failures logged via `log_warning()`
-- Admin event processing logged via existing admin logging
-
-## Phase 5: Detailed Function Specifications
-
-### 5.1 Core Authorization Function
-
-**Function**: `is_authorized_admin_event()`
-**Location**: [`src/main.c`](src/main.c) or [`src/config.c`](src/config.c)
-**Dependencies**:
-- `get_config_value()` for admin/relay pubkeys
-- `log_warning()` and `log_info()` for logging
-- `cJSON` library for event parsing
-
-**Return Values**:
-- `0` - Event is authorized for admin processing
-- `-1` - Event is unauthorized (treat as regular event)
-- `-2` - Validation error (malformed event)
-
-**Error Handling**: Detailed error messages in provided buffer for client feedback
-
-### 5.2 Enhanced Event Routing
-
-**Location**: [`main.c:3248-3340`](src/main.c:3248)
-**Integration**: Replaces existing admin event routing logic
-**Dependencies**:
-- `is_authorized_admin_event()` for authorization
-- `process_admin_event_in_config()` for admin processing
-- `store_event()` and `broadcast_event_to_subscriptions()` for regular events
-
-**Security Features**:
-- Graceful degradation for unauthorized admin events
-- Comprehensive logging of authorization attempts
-- No broadcast of admin events to subscriptions
-- Detailed error responses for failed authorization
-
-### 5.4 Defense-in-Depth Validation
-
-**Primary Validation**: In main event routing logic
-**Secondary Validation**: In `process_admin_event_in_config()` function
-**Tertiary Validation**: In individual admin command handlers
-
-**Validation Layers**:
-1. **Kind Check** - Must be admin event kind (23455/23456)
-2. **Relay Targeting Check** - Must have 'p' tag with this relay's pubkey
-3. **Admin Signature Check** - Must be signed by authorized admin (only if targeting this relay)
-4. **Processing Check** - Additional validation in admin handlers
-
-**Security Logic**:
-- If no 'p' tag for this relay → Admin event for different relay (not unauthorized)
-- If 'p' tag for this relay + wrong admin signature → "Unauthorized admin event attempt"

-### 6.2 Security Decision Points
-
-1. **Event Kind Check** - Identifies potential admin events
-2. **Authorization Validation** - Three-layer security check
-3. **Routing Decision** - Admin API vs Regular processing
-4. **Response Generation** - Unified output pipeline
-5. **Audit Logging** - Security event tracking
-
-### 6.3 Error Handling Paths
-
-**Validation Errors**: Return detailed error messages via OK response
-**Authorization Failures**: Log security event + treat as regular event
-**Processing Errors**: Return admin-specific error responses
-**System Errors**: Fallback to standard error handling
-
-This completes the comprehensive implementation plan for the enhanced admin event API structure with unified output flow architecture.

+# NIP-11 Relay Connection Implementation Plan
+
+## Overview
+Implement NIP-11 relay information fetching in the web admin interface to replace hardcoded relay pubkey and provide proper relay connection flow.
+
+## Current Issues
+1. **Hardcoded Relay Pubkey**: `getRelayPubkey()` returns hardcoded value `'4f355bdcb7cc0af728ef3cceb9615d90684bb5b2ca5f859ab0f0b704075871aa'`
+2. **Relay URL in Debug Section**: Currently in "DEBUG - TEST FETCH WITHOUT LOGIN" section (lines 336-385)
+3. **No Relay Verification**: Users can attempt admin operations without verifying relay identity
+4. **Missing NIP-11 Support**: No fetching of relay information document
+
+## Implementation Plan
+
+### 1. New Relay Connection Section (HTML Structure)
+
+Add after User Info section (around line 332):
+
+```html
+<!-- Relay Connection Section -->
+<div class="section">
+    <h2>RELAY CONNECTION</h2>
+    <div class="input-group">
+        <label for="relay-url-input">Relay URL:</label>
+        <input type="text" id="relay-url-input" value="ws://localhost:8888" placeholder="ws://localhost:8888 or wss://relay.example.com">
+    </div>
+    <div class="inline-buttons">
+        <button type="button" id="connect-relay-btn">CONNECT TO RELAY</button>
+        <button type="button" id="disconnect-relay-btn" style="display: none;">DISCONNECT</button>
+    </div>
+    <div class="status disconnected" id="relay-connection-status">NOT CONNECTED</div>
+    
+    <!-- Relay Information Display -->
+    <div id="relay-info-display" class="hidden">
+        <h3>Relay Information</h3>
+        <div class="user-info">
+            <div><strong>Name:</strong> <span id="relay-name">-</span></div>
+            <div><strong>Description:</strong> <span id="relay-description">-</span></div>
+            <div><strong>Public Key:</strong>
+                <div class="user-pubkey" id="relay-pubkey-display">-</div>
+            </div>
+            <div><strong>Software:</strong> <span id="relay-software">-</span></div>
+            <div><strong>Version:</strong> <span id="relay-version">-</span></div>
+            <div><strong>Contact:</strong> <span id="relay-contact">-</span></div>
+            <div><strong>Supported NIPs:</strong> <span id="relay-nips">-</span></div>
+        </div>
+    </div>
+</div>
+```
+
+### 2. JavaScript Implementation
+
+#### Global State Variables
+Add to global state section (around line 535):
+
+```javascript
+// Relay connection state
+let relayInfo = null;
+let isRelayConnected = false;
+let relayWebSocket = null;
+```
+
+#### NIP-11 Fetching Function
+Add new function:
+
+```javascript
+// Fetch relay information using NIP-11

+        console.error('Failed to fetch relay info:', error);
+        throw error;
+    }
+}
+```
+
+#### Relay Connection Function
+Add new function:
+
+```javascript
+// Connect to relay and fetch information
+async function connectToRelay() {
+    try {
+        const relayUrlInput = document.getElementById('relay-url-input');

+        
+        // Update UI to show connecting state
+        connectBtn.disabled = true;

+        
+        log(`Failed to connect to relay: ${error.message}`, 'ERROR');
+    }
+}
+```
+
+#### WebSocket Connection Test
+Add new function:
+
+```javascript
+// Test WebSocket connection to relay
+async function testWebSocketConnection(url) {
+    return new Promise((resolve, reject) => {
+        const timeout = setTimeout(() => {
+            ws.close();
+            reject(new Error('WebSocket connection timeout'));
+        }, 5000);
+        
+        const ws = new WebSocket(url);
+        
+        ws.onopen = () => {
+            clearTimeout(timeout);
+            console.log('WebSocket connection successful');
+            ws.close();
+            resolve();
+        };
+        
+        ws.onerror = (error) => {
+            clearTimeout(timeout);
+            console.error('WebSocket connection failed:', error);
+            reject(new Error('WebSocket connection failed'));
+        };
+        
+        ws.onclose = (event) => {
+            if (event.code !== 1000) {
+                clearTimeout(timeout);
+                reject(new Error(`WebSocket closed with code ${event.code}: ${event.reason}`));
+            }
+        };
+    });
+}
+```
+
+#### Display Relay Information
+Add new function:
+
+```javascript
+// Display relay information in the UI
+function displayRelayInfo(info) {
+    document.getElementById('relay-name').textContent = info.name || 'Unknown';
+    document.getElementById('relay-description').textContent = info.description || 'No description';
+    document.getElementById('relay-pubkey-display').textContent = info.pubkey || 'Unknown';
+    document.getElementById('relay-software').textContent = info.software || 'Unknown';
+    document.getElementById('relay-version').textContent = info.version || 'Unknown';
+    document.getElementById('relay-contact').textContent = info.contact || 'No contact info';
+    
+    // Format supported NIPs
+    let nipsText = 'None specified';
+    if (info.supported_nips && Array.isArray(info.supported_nips) && info.supported_nips.length > 0) {
+        nipsText = info.supported_nips.map(nip => `NIP-${nip.toString().padStart(2, '0')}`).join(', ');
+    }
+    document.getElementById('relay-nips').textContent = nipsText;
+}
+```
+
+#### Disconnect Function
+Add new function:
+
+```javascript
+// Disconnect from relay
+function disconnectFromRelay() {
+    console.log('Disconnecting from relay...');
+    
+    // Clear relay state
+    relayInfo = null;
+    isRelayConnected = false;
+    
+    // Close any existing connections
+    if (relayPool) {
+        const url = document.getElementById('relay-url-input').value.trim();
+        if (url) {
+            relayPool.close([url]);
+        }
+        relayPool = null;
+        subscriptionId = null;
+    }
+    
+    // Reset UI
+    const connectBtn = document.getElementById('connect-relay-btn');
+    const disconnectBtn = document.getElementById('disconnect-relay-btn');
+    const statusDiv = document.getElementById('relay-connection-status');
+    const infoDisplay = document.getElementById('relay-info-display');
+    const relayUrlInput = document.getElementById('relay-url-input');
+    
+    connectBtn.style.display = 'inline-block';
+    disconnectBtn.style.display = 'none';
+    connectBtn.disabled = false;
+    relayUrlInput.disabled = false;
+    
+    statusDiv.textContent = 'NOT CONNECTED';
+    statusDiv.className = 'status disconnected';
+    
+    infoDisplay.classList.add('hidden');
+    
+    // Reset configuration status
+    updateConfigStatus(false);
+    
+    log('Disconnected from relay', 'INFO');
+}
+```
+
+#### Update getRelayPubkey Function
+Replace existing function (around line 3142):
+
+```javascript
+// Helper function to get relay pubkey from connected relay info
+function getRelayPubkey() {
+    if (relayInfo && relayInfo.pubkey) {
+        return relayInfo.pubkey;
+    }
+    
+    // Fallback to hardcoded value if no relay connected (for testing)
+    console.warn('No relay connected, using fallback pubkey');
+    return '4f355bdcb7cc0af728ef3cceb9615d90684bb5b2ca5f859ab0f0b704075871aa';
+}
+```
+
+### 3. Event Handlers
+
+Add event handlers in the DOMContentLoaded section:
+
+```javascript
+// Relay connection event handlers
+const connectRelayBtn = document.getElementById('connect-relay-btn');
+const disconnectRelayBtn = document.getElementById('disconnect-relay-btn');
+
+if (connectRelayBtn) {
+    connectRelayBtn.addEventListener('click', function(e) {
+        e.preventDefault();
+        connectToRelay().catch(error => {
+            console.error('Connect to relay failed:', error);
+        });
+    });
+}
+
+if (disconnectRelayBtn) {
+    disconnectRelayBtn.addEventListener('click', function(e) {
+        e.preventDefault();
+        disconnectFromRelay();
+    });
+}
+```
+
+### 4. Update Existing Functions
+
+#### Update fetchConfiguration Function
+Add relay connection check at the beginning:
+
+```javascript
+async function fetchConfiguration() {
+    try {
+        console.log('=== FETCHING CONFIGURATION VIA ADMIN API ===');
+        
+        // Check if relay is connected
+        if (!isRelayConnected || !relayInfo) {
+            throw new Error('Must be connected to relay first. Please connect to relay in the Relay Connection section.');
+        }
+        
+        // ... rest of existing function
+    } catch (error) {
+        // ... existing error handling
+    }
+}
+```
+
+#### Update subscribeToConfiguration Function
+Add relay connection check:
+
+```javascript
+async function subscribeToConfiguration() {
+    try {
+        console.log('=== STARTING SIMPLEPOOL CONFIGURATION SUBSCRIPTION ===');
+
+        if (!isRelayConnected || !relayInfo) {
+            console.error('Must be connected to relay first');
+            return false;
+        }
+
+        // Use the relay URL from the connection section instead of the debug section
+        const url = document.getElementById('relay-url-input').value.trim();
+        
+        // ... rest of existing function
+    } catch (error) {
+        // ... existing error handling
+    }
+}
+```
+
+### 5. Update UI Flow
+
+#### Modify showMainInterface Function
+Update to show relay connection requirement:
+
+```javascript
+function showMainInterface() {
+    loginSection.classList.add('hidden');
+    mainInterface.classList.remove('hidden');
+    userPubkeyDisplay.textContent = userPubkey;
+    
+    // Show message about relay connection requirement
+    if (!isRelayConnected) {
+        log('Please connect to a relay to access admin functions', 'INFO');
+    }
+}
+```
+
+### 6. Remove/Update Debug Section
+
+#### Option 1: Remove Debug Section Entirely
+Remove the "DEBUG - TEST FETCH WITHOUT LOGIN" section (lines 335-385) since relay URL is now in the proper connection section.
+
+#### Option 2: Keep Debug Section for Testing
+Update the debug section to use the connected relay URL and add a note that it's for testing purposes.
+
+### 7. Error Handling
+
+Add comprehensive error handling for:
+- Network timeouts
+- Invalid relay URLs
+- Missing NIP-11 support
+- Invalid relay pubkey format
+- WebSocket connection failures
+- CORS issues
+
+### 8. Security Considerations
+
+- Validate relay pubkey format (64 hex characters)
+- Verify relay identity before admin operations
+- Handle CORS properly for NIP-11 requests
+- Sanitize relay information display
+- Warn users about connecting to untrusted relays
+
+## Testing Plan
+
+1. **NIP-11 Fetching**: Test with various relay URLs (localhost, remote relays)
+2. **Error Handling**: Test with invalid URLs, non-Nostr servers, network failures
+3. **WebSocket Connection**: Verify WebSocket connectivity after NIP-11 fetch
+4. **Admin API Integration**: Ensure admin commands use correct relay pubkey
+5. **UI Flow**: Test complete user journey from login → relay connection → admin operations
+
+## Benefits
+
+1. **Proper Relay Identification**: Uses actual relay pubkey instead of hardcoded value
+2. **Better UX**: Clear connection flow and relay information display
+3. **Protocol Compliance**: Implements NIP-11 standard for relay discovery
+4. **Security**: Verifies relay identity before admin operations
+5. **Flexibility**: Works with any NIP-11 compliant relay
+
+## Migration Notes
+
+- Existing users will need to connect to relay after this update
+- Debug section can be kept for development/testing purposes
+- All admin functions will require relay connection
+- Relay pubkey will be dynamically fetched instead of hardcoded
