 NIP-07
 ======
 `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.

 Inconsistency audit with exact fixes (treating README.md as authoritative)
 Backend auth_rules schema mismatch
 Evidence:
 Migration (creates mismatched columns):
 See "CREATE TABLE IF NOT EXISTS auth_rules ... UNIQUE(rule_type, operation, rule_target)".
 Active code uses rule_type, pattern_type, pattern_value, action:
 Insert: "INSERT INTO auth_rules (rule_type, pattern_type, pattern_value, action)"
 Delete: "DELETE FROM auth_rules WHERE rule_type = ? AND pattern_type = ? AND pattern_value = ?"
 Query mapping: map_auth_query_type_to_response()
 Queries: "... WHERE rule_type LIKE '%blacklist%'"
 Validator checks:
 "... WHERE rule_type = 'blacklist' AND pattern_type = 'pubkey' AND pattern_value = ?"
 "... WHERE rule_type = 'blacklist' AND pattern_type = 'hash' AND pattern_value = ?"
 "... WHERE rule_type = 'whitelist' AND pattern_type = 'pubkey' AND pattern_value = ?"
 Embedded schema expects pattern columns and active/indexes:
 "CREATE TABLE auth_rules ( ... )"
 "CREATE INDEX idx_auth_rules_pattern ON auth_rules(pattern_type, pattern_value)"
 "CREATE INDEX idx_auth_rules_active ON auth_rules(active)"
 Fix (update migration to align with sql_schema.h/config.c):
 Replace the DDL at "create_auth_rules_sql" with: CREATE TABLE IF NOT EXISTS auth_rules ( id INTEGER PRIMARY KEY AUTOINCREMENT, rule_type TEXT NOT NULL, -- 'whitelist' | 'blacklist' pattern_type TEXT NOT NULL, -- 'pubkey' | 'hash' | future pattern_value TEXT NOT NULL, -- hex pubkey/hash action TEXT NOT NULL, -- 'allow' | 'deny' active INTEGER DEFAULT 1, created_at INTEGER DEFAULT (strftime('%s','now')), UNIQUE(rule_type, pattern_type, pattern_value) );
 After creation, also create indexes as in "sql_schema.h":
 CREATE INDEX idx_auth_rules_pattern ON auth_rules(pattern_type, pattern_value);
 CREATE INDEX idx_auth_rules_type ON auth_rules(rule_type);
 CREATE INDEX idx_auth_rules_active ON auth_rules(active);
 Duplicate UI function + stale DOM id usage
 Evidence:
 Duplicate definition of disconnectFromRelay() and disconnectFromRelay(); the second overwrites the first and uses legacy element access paths.
 Stale variable: "const relayUrl = document.getElementById('relay-url');" — no element with id="relay-url" exists; the real input is "relay-connection-url" and is referenced as "relayConnectionUrl".
 Calls using relayUrl.value.trim() (must use relayConnectionUrl):
 "sendConfigUpdateCommand() publish URL"
 "loadAuthRules() publish URL"
 "deleteAuthRule() publish URL"
 Tests:
 "testGetAuthRules()"
 "testClearAuthRules()"
 "testAddBlacklist()"
 "testAddWhitelist()"
 "testConfigQuery()"
 "testPostEvent()"
 Fix:
 Remove the duplicate legacy function entirely: delete the second disconnectFromRelay().
 Remove stale variable: delete "const relayUrl = document.getElementById('relay-url');".
 Replace every relayUrl.value.trim() occurrence with relayConnectionUrl.value.trim() at the lines listed above.
 Supported NIPs inconsistency (README vs UI fallback)
 Evidence:
 README implemented NIPs checklist (authoritative): "NIPs list" shows: 1, 9, 11, 13, 15, 20, 33, 40, 42 implemented.
 UI fallback for manual relay info includes unsupported/undocumented NIPs and misses implemented ones:
 "supported_nips: [1, 2, 4, 9, 11, 12, 15, 16, 20, 22]"
 "supported_nips: [1, 2, 4, 9, 11, 12, 15, 16, 20, 22]"
 Fix:
 Replace both arrays with: [1, 9, 11, 13, 15, 20, 33, 40, 42]
 Config key mismatches (README vs UI edit form)
 Evidence:
 README keys (authoritative): "Available Configuration Keys"–(README.md:110)
 relay_description, relay_contact, max_connections, max_subscriptions_per_client, max_event_tags, max_content_length, auth_enabled, nip42_auth_required, nip42_auth_required_kinds, nip42_challenge_timeout, pow_min_difficulty, nip40_expiration_enabled
 UI currently declares/uses many non-README keys:
 Field types: "fieldTypes" include nip42_auth_required_events, nip42_auth_required_subscriptions, relay_port, pow_mode, nip40_expiration_strict, nip40_expiration_filter, nip40_expiration_grace_period, max_total_subscriptions, max_filters_per_subscription, max_message_length, default_limit, max_limit.
 Descriptions: "descriptions" reflect the same non-README keys.
 Fix:
 Restrict UI form generation to README keys and rename mismatches:
 Combine nip42_auth_required_events/subscriptions into README’s "nip42_auth_required" (boolean).
 Rename nip42_challenge_expiration to "nip42_challenge_timeout".
 Remove or hide (advanced section) non-README keys: relay_port, pow_mode, nip40_expiration_strict, nip40_expiration_filter, nip40_expiration_grace_period, max_total_subscriptions, max_filters_per_subscription, max_message_length, default_limit, max_limit.
 Update both "fieldTypes" and "descriptions" to reflect only README keys (data types and labels consistent).
 First-time startup port override (-p) ignored when -a and -r are also provided
 Observation:
 You confirmed: first run with -p 7777 works, but with -p plus -a and -r the override isn’t honored.
 Likely cause:
 The code path that handles admin/relay key overrides on first-time setup bypasses persisting the CLI port override to config/unified cache before server start, so "start_websocket_relay(-1, ...)" falls back to default.
 Fix:
 Ensure first_time_startup_sequence applies cli_options.port_override to persistent config and cache BEFORE default config insertion and before starting the server. Specifically:
 In the first-time path (main):
 After "first_time_startup_sequence(&cli_options)" and before creating defaults on the -a/-r path at "populate_default_config_values()", write the port override:
 set_config_value_in_table("relay_port", "<port>", "integer", "WebSocket port", "relay", 0);
 and update unified cache if required by the port resolution code.
 Verify the code path where -a/-r trigger direct table population also applies/overwrites the port with the CLI-provided value.
 Add a regression test to assert that -p is honored with and without -a/-r on first run.
 Minor consistency recommendations
 UI NIP-11 fallback version string:
 Consider aligning with backend version source (e.g., src/version.h). The UI currently hardcodes "1.0.0" at "version: '1.0.0'".
 UI hardcoded relay pubkey fallback:
 "getRelayPubkey()" returns a constant when not connected. Safe for dev, but should not leak into production paths.
 Added TODO items (as requested)
 The following todos were added/organized:
 Remove duplicate disconnectFromRelay() and standardize to relay-connection-url
 Replace all relayUrl.value references with relayConnectionUrl.value in api/index.html
 Align Supported NIPs fallback arrays in api/index.html with README (1,9,11,13,15,20,33,40,42)
 Update config form keys/descriptions in api/index.html to match README keys
 Fix backend auth_rules migration in src/main.c to match src/sql_schema.h/src/config.c
 Investigate and fix first-time startup port override ignored when -a and -r are provided
 Add tests for port override and auth_rules flows
 Rebuild via ./make_and_restart_relay.sh and validate against README

 # 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
 async function fetchRelayInfo(relayUrl) {
    try {
        console.log('=== FETCHING RELAY INFO VIA NIP-11 ===');
        console.log('Relay URL:', relayUrl);
        // Convert WebSocket URL to HTTP URL for NIP-11
        let httpUrl = relayUrl;
        if (relayUrl.startsWith('ws://')) {
            httpUrl = relayUrl.replace('ws://', 'http://');
        } else if (relayUrl.startsWith('wss://')) {
            httpUrl = relayUrl.replace('wss://', 'https://');
        }
        console.log('HTTP URL for NIP-11:', httpUrl);
        // Fetch relay information document
        const response = await fetch(httpUrl, {
            method: 'GET',
            headers: {
                'Accept': 'application/nostr+json'
            },
            // Add timeout
            signal: AbortSignal.timeout(10000) // 10 second timeout
        });
        if (!response.ok) {
            throw new Error(`HTTP ${response.status}: ${response.statusText}`);
        }
        const contentType = response.headers.get('content-type');
        if (!contentType || !contentType.includes('application/json')) {
            throw new Error(`Invalid content type: ${contentType}. Expected application/json or application/nostr+json`);
        }
        const relayInfoData = await response.json();
        console.log('Fetched relay info:', relayInfoData);
        // Validate required fields
        if (!relayInfoData.pubkey) {
            throw new Error('Relay information missing required pubkey field');
        }
        // Validate pubkey format (64 hex characters)
        if (!/^[0-9a-fA-F]{64}$/.test(relayInfoData.pubkey)) {
            throw new Error(`Invalid relay pubkey format: ${relayInfoData.pubkey}`);
        }
        return relayInfoData;
    } catch (error) {
        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');
        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 url = relayUrlInput.value.trim();
        if (!url) {
            throw new Error('Please enter a relay URL');
        }
        // Update UI to show connecting state
        connectBtn.disabled = true;
        statusDiv.textContent = 'CONNECTING...';
        statusDiv.className = 'status connected';
        console.log('Connecting to relay:', url);
        // Fetch relay information via NIP-11
        console.log('Fetching relay information...');
        const fetchedRelayInfo = await fetchRelayInfo(url);
        // Test WebSocket connection
        console.log('Testing WebSocket connection...');
        await testWebSocketConnection(url);
        // Store relay information
        relayInfo = fetchedRelayInfo;
        isRelayConnected = true;
        // Update UI with relay information
        displayRelayInfo(relayInfo);
        // Update connection status
        statusDiv.textContent = 'CONNECTED';
        statusDiv.className = 'status connected';
        // Update button states
        connectBtn.style.display = 'none';
        disconnectBtn.style.display = 'inline-block';
        relayUrlInput.disabled = true;
        // Show relay info
        infoDisplay.classList.remove('hidden');
        console.log('Successfully connected to relay:', relayInfo.name || url);
        log(`Connected to relay: ${relayInfo.name || url}`, 'INFO');
    } catch (error) {
        console.error('Failed to connect to relay:', error);
        // Reset UI state
        const connectBtn = document.getElementById('connect-relay-btn');
        const statusDiv = document.getElementById('relay-connection-status');
        connectBtn.disabled = false;
        statusDiv.textContent = `CONNECTION FAILED: ${error.message}`;
        statusDiv.className = 'status error';
        // Clear any partial state
        relayInfo = null;
        isRelayConnected = false;
        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
