-`window.nostr` capability for web browsers
-------------------------------------------
-
-`draft` `optional`
-
-The `window.nostr` object may be made available by web browsers or extensions and websites or web-apps may make use of it after checking its availability.
-
-That object must define the following methods:
-
-```
-async window.nostr.getPublicKey(): string // returns a public key as hex
-async window.nostr.signEvent(event: { created_at: number, kind: number, tags: string[][], content: string }): Event // takes an event object, adds `id`, `pubkey` and `sig` and returns it
-```
-
-Aside from these two basic above, the following functions can also be implemented optionally:
-```
-async window.nostr.nip04.encrypt(pubkey, plaintext): string // returns ciphertext and iv as specified in nip-04 (deprecated)
-async window.nostr.nip04.decrypt(pubkey, ciphertext): string // takes ciphertext and iv as specified in nip-04 (deprecated)
-async window.nostr.nip44.encrypt(pubkey, plaintext): string // returns ciphertext as specified in nip-44
-async window.nostr.nip44.decrypt(pubkey, ciphertext): string // takes ciphertext as specified in nip-44
-```
-
-### Recommendation to Extension Authors
-To make sure that the `window.nostr` is available to nostr clients on page load, the authors who create Chromium and Firefox extensions should load their scripts by specifying `"run_at": "document_end"` in the extension's manifest.
-
-
-### Implementation
-
-See https://github.com/aljazceru/awesome-nostr#nip-07-browser-extensions.

+### Dynamic Configuration Updates
+
+C-Relay supports **dynamic configuration updates** without requiring a restart for most settings. Configuration parameters are categorized as either **dynamic** (can be updated immediately) or **restart-required** (require relay restart to take effect).
+
+**Dynamic Configuration Parameters (No Restart Required):**
+- All relay information (NIP-11) settings: `relay_name`, `relay_description`, `relay_contact`, `relay_software`, `relay_version`, `supported_nips`, `language_tags`, `relay_countries`, `posting_policy`, `payments_url`
+- Authentication settings: `auth_enabled`, `nip42_auth_required`, `nip42_auth_required_kinds`, `nip42_challenge_timeout`
+- Subscription limits: `max_subscriptions_per_client`, `max_total_subscriptions`
+- Event validation limits: `max_event_tags`, `max_content_length`, `max_message_length`
+- Proof of Work settings: `pow_min_difficulty`, `pow_mode`
+- Event expiration settings: `nip40_expiration_enabled`, `nip40_expiration_strict`, `nip40_expiration_filter`, `nip40_expiration_grace_period`
+
+**Restart-Required Configuration Parameters:**
+- Connection settings: `max_connections`, `relay_port`
+- Database and core system settings
+
+When updating configuration, the admin API response will indicate whether a restart is required for each parameter. Dynamic updates take effect immediately and are reflected in NIP-11 relay information documents without restart.
+
 ### Response Format
 
 All admin commands return **signed EVENT responses** via WebSocket following standard Nostr protocol. Responses use JSON content with structured data.

-# 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):

-        
-        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.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;

-    
-    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
