-`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.

-# 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
- */
-int is_authorized_admin_event(cJSON* event, char* error_message, size_t error_size) {

-                }
-            }
-        }
-    }
-    
-    if (!has_relay_target) {
-        // Admin event for different relay - not unauthorized, just not for us
-        snprintf(error_message, error_size, "admin_auth: admin event for different relay");
-        return -1;
-    }
-    
-    // Validation Layer 3: Admin Signature Check (only if targeting this relay)
-    const char* event_pubkey = cJSON_GetStringValue(pubkey_obj);

-```
-
-#### 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) {

-
-// Enhanced secure code with consolidated authorization:

-    if (kind_obj && cJSON_IsNumber(kind_obj)) {
-        int event_kind = (int)cJSON_GetNumberValue(kind_obj);
-        
-        // Check if this is an admin event
-        if (event_kind == 23455 || event_kind == 23456) {
-            // Use consolidated authorization check
-            char auth_error[512] = {0};
-            int auth_result = is_authorized_admin_event(event, auth_error, sizeof(auth_error));

-                char admin_error[512] = {0};
-                int admin_result = process_admin_event_in_config(event, admin_error, sizeof(admin_error), wsi);
-                
-                if (admin_result != 0) {
-                    result = -1;
-                    strncpy(error_message, admin_error, sizeof(error_message) - 1);
-                }
-                // Admin events are NOT broadcast to subscriptions
-            } else {
-                // Unauthorized admin event - treat as regular event
-                log_warning("Unauthorized admin event treated as regular event");
-                if (store_event(event) != 0) {
-                    result = -1;
-                    strncpy(error_message, "error: failed to store event", sizeof(error_message) - 1);
-                } else {
-                    broadcast_event_to_subscriptions(event);
-                }
-            }

-            }
-        }
-    }
-}
-```
-
-### 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.

+### 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`

+- 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.
