v0.4.9 - Working on dm admin

- Add cache refresh mechanism for config updates
- Implement selective re-initialization for NIP-11 relay info changes
- Categorize configs as dynamic vs restart-required using requires_restart field
- Enhance admin API responses with restart requirement information
- Add comprehensive test for dynamic config updates
- Update documentation for dynamic configuration capabilities

Most relay settings can now be updated via admin API without requiring restart, improving operational flexibility while maintaining stability for critical changes.

-Expiration Timestamp
---------------------
-
-`draft` `optional`
-
-The `expiration` tag enables users to specify a unix timestamp at which the message SHOULD be considered expired (by relays and clients) and SHOULD be deleted by relays.
-
-#### Spec
-
-```
-tag: expiration
-values:
- - [UNIX timestamp in seconds]: required
-```
-
-#### Example
-
-```json
-{
-  "pubkey": "<pub-key>",
-  "created_at": 1000000000,
-  "kind": 1,
-  "tags": [
-    ["expiration", "1600000000"]
-  ],
-  "content": "This message will expire at the specified timestamp and be deleted by relays.\n",
-  "id": "<event-id>"
-}
-```
-
-Note: The timestamp should be in the same format as the created_at timestamp and should be interpreted as the time at which the message should be deleted by relays.
-
-Client Behavior
----------------
-
-Clients SHOULD use the `supported_nips` field to learn if a relay supports this NIP. Clients SHOULD NOT send expiration events to relays that do not support this NIP.
-
-Clients SHOULD ignore events that have expired.
-
-Relay Behavior
---------------
-
-Relays MAY NOT delete expired messages immediately on expiration and MAY persist them indefinitely.
-Relays SHOULD NOT send expired events to clients, even if they are stored.
-Relays SHOULD drop any events that are published to them if they are expired.
-An expiration timestamp does not affect storage of ephemeral events.
-
-Suggested Use Cases
--------------------
-
-* Temporary announcements - This tag can be used to make temporary announcements. For example, an event organizer could use this tag to post announcements about an upcoming event.
-* Limited-time offers - This tag can be used by businesses to make limited-time offers that expire after a certain amount of time. For example, a business could use this tag to make a special offer that is only available for a limited time.
-
-#### Warning
-The events could be downloaded by third parties as they are publicly accessible all the time on the relays.
-So don't consider expiring messages as a security feature for your conversations or other uses.

-
-Authentication of clients to relays
------------------------------------
-
-`draft` `optional`
-
-This NIP defines a way for clients to authenticate to relays by signing an ephemeral event.
-
-## Motivation
-
-A relay may want to require clients to authenticate to access restricted resources. For example,
-
-  - A relay may request payment or other forms of whitelisting to publish events -- this can naïvely be achieved by limiting publication to events signed by the whitelisted key, but with this NIP they may choose to accept any events as long as they are published from an authenticated user;
-  - A relay may limit access to `kind: 4` DMs to only the parties involved in the chat exchange, and for that it may require authentication before clients can query for that kind.
-  - A relay may limit subscriptions of any kind to paying users or users whitelisted through any other means, and require authentication.
-
-## Definitions
-
-### New client-relay protocol messages
-
-This NIP defines a new message, `AUTH`, which relays CAN send when they support authentication and clients can send to relays when they want to authenticate. When sent by relays the message has the following form:
-
-```
-["AUTH", <challenge-string>]
-```
-
-And, when sent by clients, the following form:
-
-```
-["AUTH", <signed-event-json>]
-```
-
-Clients MAY provide signed events from multiple pubkeys in a sequence of `AUTH` messages. Relays MUST treat all pubkeys as authenticated accordingly.
-
-`AUTH` messages sent by clients MUST be answered with an `OK` message, like any `EVENT` message.
-
-### Canonical authentication event
-
-The signed event is an ephemeral event not meant to be published or queried, it must be of `kind: 22242` and it should have at least two tags, one for the relay URL and one for the challenge string as received from the relay. Relays MUST exclude `kind: 22242` events from being broadcasted to any client. `created_at` should be the current time. Example:
-
-```jsonc
-{
-  "kind": 22242,
-  "tags": [
-    ["relay", "wss://relay.example.com/"],
-    ["challenge", "challengestringhere"]
-  ],
-  // other fields...
-}
-```
-
-### `OK` and `CLOSED` machine-readable prefixes
-
-This NIP defines two new prefixes that can be used in `OK` (in response to event writes by clients) and `CLOSED` (in response to rejected subscriptions by clients):
-
-- `"auth-required: "` - for when a client has not performed `AUTH` and the relay requires that to fulfill the query or write the event.
-- `"restricted: "` - for when a client has already performed `AUTH` but the key used to perform it is still not allowed by the relay or is exceeding its authorization.
-
-## Protocol flow
-
-At any moment the relay may send an `AUTH` message to the client containing a challenge. The challenge is valid for the duration of the connection or until another challenge is sent by the relay. The client MAY decide to send its `AUTH` event at any point and the authenticated session is valid afterwards for the duration of the connection.
-
-### `auth-required` in response to a `REQ` message
-
-Given that a relay is likely to require clients to perform authentication only for certain jobs, like answering a `REQ` or accepting an `EVENT` write, these are some expected common flows:
-
-```
-relay: ["AUTH", "<challenge>"]
-client: ["REQ", "sub_1", {"kinds": [4]}]
-relay: ["CLOSED", "sub_1", "auth-required: we can't serve DMs to unauthenticated users"]
-client: ["AUTH", {"id": "abcdef...", ...}]
-client: ["AUTH", {"id": "abcde2...", ...}]
-relay: ["OK", "abcdef...", true, ""]
-relay: ["OK", "abcde2...", true, ""]
-client: ["REQ", "sub_1", {"kinds": [4]}]
-relay: ["EVENT", "sub_1", {...}]
-relay: ["EVENT", "sub_1", {...}]
-relay: ["EVENT", "sub_1", {...}]
-relay: ["EVENT", "sub_1", {...}]
-...
-```
-
-In this case, the `AUTH` message from the relay could be sent right as the client connects or it can be sent immediately before the `CLOSED` is sent. The only requirement is that _the client must have a stored challenge associated with that relay_ so it can act upon that in response to the `auth-required` `CLOSED` message.
-
-### `auth-required` in response to an `EVENT` message
-
-The same flow is valid for when a client wants to write an `EVENT` to the relay, except now the relay sends back an `OK` message instead of a `CLOSED` message:
-
-```
-relay: ["AUTH", "<challenge>"]
-client: ["EVENT", {"id": "012345...", ...}]
-relay: ["OK", "012345...", false, "auth-required: we only accept events from registered users"]
-client: ["AUTH", {"id": "abcdef...", ...}]
-relay: ["OK", "abcdef...", true, ""]
-client: ["EVENT", {"id": "012345...", ...}]
-relay: ["OK", "012345...", true, ""]
-```
-
-## Signed Event Verification
-
-To verify `AUTH` messages, relays must ensure:
-
-  - that the `kind` is `22242`;
-  - that the event `created_at` is close (e.g. within ~10 minutes) of the current time;
-  - that the `"challenge"` tag matches the challenge sent before;
-  - that the `"relay"` tag matches the relay URL:
-    - URL normalization techniques can be applied. For most cases just checking if the domain name is correct should be enough.

+## 🌐 Web Admin Interface
 
+C-Relay includes a **built-in web-based administration interface** accessible at `http://localhost:8888/api/`. The interface provides:
+
+- **Real-time Configuration Management**: View and edit all relay settings through a web UI
+- **Database Statistics Dashboard**: Monitor event counts, storage usage, and performance metrics
+- **Auth Rules Management**: Configure whitelist/blacklist rules for pubkeys
+- **NIP-42 Authentication**: Secure access using your Nostr identity
+- **Event-Based Updates**: All changes are applied as cryptographically signed Nostr events
+
+The web interface serves embedded static files with no external dependencies and includes proper CORS headers for browser compatibility.
+
+## 🔧 Administrator API
+
+C-Relay uses an innovative **event-based administration system** where all configuration and management commands are sent as signed Nostr events using the admin private key generated during first startup. All admin commands use **NIP-44 encrypted command arrays** for security and compatibility.
+
+### Authentication
+
+All admin commands require signing with the admin private key displayed during first-time startup. **Save this key securely** - it cannot be recovered and is needed for all administrative operations.
+
+### Event Structure
+
+All admin commands use the same unified event structure with NIP-44 encrypted content:
+
+**Admin Command Event:**
+```json
+{
+  "id": "event_id",
+  "pubkey": "admin_public_key",
+  "created_at": 1234567890,
+  "kind": 23456,
+  "content": "AqHBUgcM7dXFYLQuDVzGwMST1G8jtWYyVvYxXhVGEu4nAb4LVw...",
+  "tags": [
+    ["p", "relay_public_key"]
+  ],
+  "sig": "event_signature"
+}
+```
+
+The `content` field contains a NIP-44 encrypted JSON array representing the command.
+
+**Admin Response Event:**
+```json
+["EVENT", "temp_sub_id", {
+  "id": "response_event_id",
+  "pubkey": "relay_public_key",
+  "created_at": 1234567890,
+  "kind": 23457,
+  "content": "BpKCVhfN8eYtRmPqSvWxZnMkL2gHjUiOp3rTyEwQaS5dFg...",
+  "tags": [
+    ["p", "admin_public_key"]
+  ],
+  "sig": "response_event_signature"
+}]
+```
+
+The `content` field contains a NIP-44 encrypted JSON response object.
+
+### Admin Commands
+
+All commands are sent as NIP-44 encrypted JSON arrays in the event content. The following table lists all available commands:
+
+| Command Type | Command Format | Description |
+|--------------|----------------|-------------|
+| **Configuration Management** |
+| `config_update` | `["config_update", [{"key": "auth_enabled", "value": "true", "data_type": "boolean", "category": "auth"}, {"key": "relay_description", "value": "My Relay", "data_type": "string", "category": "relay"}, ...]]` | Update relay configuration parameters (supports multiple updates) |
+| `config_query` | `["config_query", "all"]` | Query all configuration parameters |
+| **Auth Rules Management** |
+| `auth_add_blacklist` | `["blacklist", "pubkey", "abc123..."]` | Add pubkey to blacklist |
+| `auth_add_whitelist` | `["whitelist", "pubkey", "def456..."]` | Add pubkey to whitelist |
+| `auth_delete_rule` | `["delete_auth_rule", "blacklist", "pubkey", "abc123..."]` | Delete specific auth rule |
+| `auth_query_all` | `["auth_query", "all"]` | Query all auth rules |
+| `auth_query_type` | `["auth_query", "whitelist"]` | Query specific rule type |
+| `auth_query_pattern` | `["auth_query", "pattern", "abc123..."]` | Query specific pattern |
+| **System Commands** |
+| `system_clear_auth` | `["system_command", "clear_all_auth_rules"]` | Clear all auth rules |
+| `system_status` | `["system_command", "system_status"]` | Get system status |
+| `stats_query` | `["stats_query"]` | Get comprehensive database statistics |
+
+### Available Configuration Keys
+
+**Basic Relay Settings:**
+- `relay_name`: Relay name (displayed in NIP-11)
+- `relay_description`: Relay description text
+- `relay_contact`: Contact information
+- `relay_software`: Software URL
+- `relay_version`: Software version
+- `supported_nips`: Comma-separated list of supported NIP numbers (e.g., "1,2,4,9,11,12,13,15,16,20,22,33,40,42")
+- `language_tags`: Comma-separated list of supported language tags (e.g., "en,es,fr" or "*" for all)
+- `relay_countries`: Comma-separated list of supported country codes (e.g., "US,CA,MX" or "*" for all)
+- `posting_policy`: Posting policy URL or text
+- `payments_url`: Payment URL for premium features
+- `max_connections`: Maximum concurrent connections
+- `max_subscriptions_per_client`: Max subscriptions per client
+- `max_event_tags`: Maximum tags per event
+- `max_content_length`: Maximum event content length
+
+**Authentication & Access Control:**
+- `auth_enabled`: Enable whitelist/blacklist auth rules (`true`/`false`)
+- `nip42_auth_required`: Enable NIP-42 cryptographic authentication (`true`/`false`)
+- `nip42_auth_required_kinds`: Event kinds requiring NIP-42 auth (comma-separated)
+- `nip42_challenge_timeout`: NIP-42 challenge expiration seconds
+
+**Proof of Work & Validation:**
+- `pow_min_difficulty`: Minimum proof-of-work difficulty
+- `nip40_expiration_enabled`: Enable event expiration (`true`/`false`)
+
+### 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.

+# C-Relay Administrator API Implementation Plan
+
+## Problem Analysis
+
+### Current Issues Identified:
+
+1. **Schema Mismatch**: Storage system (config.c) vs Validation system (request_validator.c) use different column names and values
+2. **Missing API Endpoint**: No way to clear auth_rules table for testing
+3. **Configuration Gap**: Auth rules enforcement may not be properly enabled
+4. **Documentation Gap**: Admin API commands not documented
+
+### Root Cause: Auth Rules Schema Inconsistency
+
+**Current Schema (sql_schema.h lines 140-150):**
+```sql
+CREATE TABLE auth_rules (
+    rule_type TEXT CHECK (rule_type IN ('whitelist', 'blacklist')),
+    pattern_type TEXT CHECK (pattern_type IN ('pubkey', 'hash')),  
+    pattern_value TEXT,
+    action TEXT CHECK (action IN ('allow', 'deny')),
+    active INTEGER DEFAULT 1
+);
+```
+
+**Storage Implementation (config.c):**
+- Stores: `rule_type='blacklist'`, `pattern_type='pubkey'`, `pattern_value='hex'`, `action='allow'`
+
+**Validation Implementation (request_validator.c):**
+- Queries: `rule_type='pubkey_blacklist'`, `rule_target='hex'`, `operation='event'`, `enabled=1`
+
+**MISMATCH**: Validator looks for non-existent columns and wrong rule_type values!
+
+## Proposed Solution Architecture
+
+### Phase 1: API Documentation & Standardization
+
+#### Admin API Commands (via WebSocket with admin private key)
+
+**Kind 23456: Unified Admin API (Ephemeral)**
+- Configuration management: Update relay settings, limits, authentication policies
+- Auth rules: Add/remove/query whitelist/blacklist rules
+- System commands: clear rules, status, cache management
+- **Unified Format**: All commands use NIP-44 encrypted content with `["p", "relay_pubkey"]` tags
+- **Command Types**:
+  - Configuration: `["config_key", "config_value"]`
+  - Auth rules: `["rule_type", "pattern_type", "pattern_value"]`
+  - Queries: `["auth_query", "filter"]` or `["system_command", "command_name"]`
+- **Security**: All admin commands use NIP-44 encryption for privacy and security
+
+#### Configuration Commands (using Kind 23456)
+
+1. **Update Configuration**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["relay_description", "My Relay"]`
+
+2. **Query System Status**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["system_command", "system_status"]`
+
+#### Auth Rules and System Commands (using Kind 23456)
+
+1. **Clear All Auth Rules**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["system_command", "clear_all_auth_rules"]`
+
+2. **Query All Auth Rules**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["auth_query", "all"]`
+
+3. **Add Blacklist Rule**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["blacklist", "pubkey", "deadbeef1234abcd..."]`
+
+### Phase 2: Auth Rules Schema Alignment
+
+#### Option A: Fix Validator to Match Schema (RECOMMENDED)
+
+**Update request_validator.c:**
+```sql
+-- OLD (broken):
+WHERE rule_type = 'pubkey_blacklist' AND rule_target = ? AND operation = ? AND enabled = 1
+
+-- NEW (correct):
+WHERE rule_type = 'blacklist' AND pattern_type = 'pubkey' AND pattern_value = ? AND active = 1
+```
+
+**Benefits:**
+- Matches actual database schema
+- Simpler rule_type values ('blacklist' vs 'pubkey_blacklist')  
+- Uses existing columns (pattern_value vs rule_target)
+- Consistent with storage implementation
+
+#### Option B: Update Schema to Match Validator (NOT RECOMMENDED)
+
+Would require changing schema, migration scripts, and storage logic.
+
+### Phase 3: Implementation Priority
+
+#### High Priority (Critical for blacklist functionality):
+1. Fix request_validator.c schema mismatch
+2. Ensure auth_required configuration is enabled
+3. Update tests to use unified ephemeral event kind (23456)
+4. Test blacklist enforcement
+
+#### Medium Priority (Enhanced Admin Features):
+1. **Implement NIP-44 Encryption Support**:
+   - Detect NIP-44 encrypted content for Kind 23456 events
+   - Parse `encrypted_tags` field from content JSON
+   - Decrypt using admin privkey and relay pubkey
+   - Process decrypted tags as normal commands
+2. Add clear_all_auth_rules system command
+3. Add auth rule query functionality (both standard and encrypted modes)
+4. Add configuration discovery (list available config keys)
+5. Enhanced error reporting in admin API
+6. Conflict resolution (same pubkey in whitelist + blacklist)
+
+#### Security Priority (NIP-44 Implementation):
+1. **Encryption Detection Logic**: Check for empty tags + encrypted_tags field
+2. **Key Pair Management**: Use admin private key + relay public key for NIP-44
+3. **Backward Compatibility**: Support both standard and encrypted modes
+4. **Error Handling**: Graceful fallback if decryption fails
+5. **Performance**: Cache decrypted results to avoid repeated decryption
+
+#### Low Priority (Documentation & Polish):
+1. Complete README.md API documentation
+2. Example usage scripts
+3. Admin client tools
+
+### Phase 4: Expected API Structure
+
+#### README.md Documentation Format:
+
+```markdown
+# C-Relay Administrator API
+
+## Authentication
+All admin commands require signing with the admin private key generated during first startup.
+
+## Unified Admin API (Kind 23456 - Ephemeral)
+Update relay configuration parameters or query available settings.
+
+**Configuration Update Event:**
+```json
+{
+  "kind": 23456,
+  "content": "base64_nip44_encrypted_command_array",
+  "tags": [["p", "relay_pubkey"]]
+}
+```
+*Encrypted content contains:* `["relay_description", "My Relay Description"]`
+
+**Auth Rules Management:**
+
+**Add Rule Event:**
+```json
+{
+  "kind": 23456,
+  "content": "{\"action\":\"add\",\"description\":\"Block malicious user\"}",
+  "tags": [
+    ["blacklist", "pubkey", "deadbeef1234..."]
+  ]
+}
+```
+
+**Remove Rule Event:**
+```json
+{
+  "kind": 23456,
+  "content": "{\"action\":\"remove\",\"description\":\"Unblock user\"}",
+  "tags": [
+    ["blacklist", "pubkey", "deadbeef1234..."]
+  ]
+}
+```
+
+**Query All Auth Rules:**
+```json
+{
+  "kind": 23456,
+  "content": "{\"query\":\"list_auth_rules\",\"description\":\"Get all rules\"}",
+  "tags": [
+    ["auth_query", "all"]
+  ]
+}
+```
+
+**Query Whitelist Rules Only:**
+```json
+{
+  "kind": 23456,
+  "content": "{\"query\":\"list_auth_rules\",\"description\":\"Get whitelist\"}",
+  "tags": [
+    ["auth_query", "whitelist"]
+  ]
+}
+```
+
+**Check Specific Pattern:**
+```json
+{
+  "kind": 23456,
+  "content": "{\"query\":\"check_pattern\",\"description\":\"Check if pattern exists\"}",
+  "tags": [
+    ["auth_query", "pattern", "deadbeef1234..."]
+  ]
+}
+```
+
+## System Management (Kind 23456 - Ephemeral)
+System administration commands using the same kind as auth rules.
+
+**Clear All Auth Rules:**
+```json
+{
+  "kind": 23456,
+  "content": "{\"action\":\"clear_all\",\"description\":\"Clear all auth rules\"}",
+  "tags": [
+    ["system_command", "clear_all_auth_rules"]
+  ]
+}
+```
+
+**System Status:**
+```json
+{
+  "kind": 23456,
+  "content": "{\"action\":\"system_status\",\"description\":\"Get system status\"}",
+  "tags": [
+    ["system_command", "system_status"]
+  ]
+}
+```
+
+## Response Format
+All admin commands return JSON responses via WebSocket:
+
+**Success Response:**
+```json
+["OK", "event_id", true, "success_message"]
+```
+
+**Error Response:**  
+```json
+["OK", "event_id", false, "error_message"]
+```
+
+## Configuration Keys
+- `relay_description`: Relay description text
+- `relay_contact`: Contact information  
+- `auth_enabled`: Enable authentication system
+- `max_connections`: Maximum concurrent connections
+- `pow_min_difficulty`: Minimum proof-of-work difficulty
+- ... (full list of config keys)
+
+## Examples
+
+### Enable Authentication & Add Blacklist
+```bash
+# 1. Enable auth system
+nak event -k 23456 --content "base64_nip44_encrypted_command" \
+  -t "auth_enabled=true" \
+  --sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
+
+# 2. Add user to blacklist
+nak event -k 23456 --content '{"action":"add","description":"Spam user"}' \
+  -t "blacklist=pubkey;$SPAM_USER_PUBKEY" \
+  --sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
+
+# 3. Query all auth rules
+nak event -k 23456 --content '{"query":"list_auth_rules","description":"Get all rules"}' \
+  -t "auth_query=all" \
+  --sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
+
+# 4. Clear all rules for testing
+nak event -k 23456 --content '{"action":"clear_all","description":"Clear all rules"}' \
+  -t "system_command=clear_all_auth_rules" \
+  --sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
+```
+
+## Expected Response Formats
+
+### Configuration Query Response
+```json
+["EVENT", "subscription_id", {
+  "kind": 23457,
+  "content": "base64_nip44_encrypted_response",
+  "tags": [["p", "admin_pubkey"]]
+}]
+```
+
+### Current Config Response

+  "tags": [["response_type", "auth_rules_list"], ["query_type", "all"]]
+}]
+```
+
+### Pattern Check Response

+
+## NIP-44 Encryption Implementation Details
+
+### Server-Side Detection Logic
+```c
+// In admin event processing function
+bool is_encrypted_command(struct nostr_event *event) {
+    // Check if Kind 23456 with NIP-44 encrypted content
+    if (event->kind == 23456 &&
+        event->tags_count == 0) {
+        return true;
+    }
+    return false;
+}
+
+cJSON *decrypt_admin_tags(struct nostr_event *event) {
+    cJSON *content_json = cJSON_Parse(event->content);
+    if (!content_json) return NULL;
+    
+    cJSON *encrypted_tags = cJSON_GetObjectItem(content_json, "encrypted_tags");
+    if (!encrypted_tags) {
+        cJSON_Delete(content_json);
+        return NULL;
+    }
+    
+    // Decrypt using NIP-44 with admin pubkey and relay privkey
+    char *decrypted = nip44_decrypt(
+        cJSON_GetStringValue(encrypted_tags),
+        admin_pubkey,           // Shared secret with admin
+        relay_private_key       // Our private key
+    );
+    
+    cJSON *decrypted_tags = cJSON_Parse(decrypted);
+    free(decrypted);
+    cJSON_Delete(content_json);
+    
+    return decrypted_tags; // Returns tag array: [["key1", "val1"], ["key2", "val2"]]
+}
+```
+
+### Admin Event Processing Flow
+1. **Receive Event**: Kind 23456 with admin signature
+2. **Check Mode**: Empty tags = encrypted, populated tags = standard
+3. **Decrypt if Needed**: Extract and decrypt `encrypted_tags` from content
+4. **Process Commands**: Use decrypted/standard tags for command processing
+5. **Execute**: Same logic for both modes after tag extraction
+6. **Respond**: Standard response format (optionally encrypt response)
+
+### Security Benefits
+- **Command Privacy**: Admin operations invisible in event tags
+- **Replay Protection**: NIP-44 includes timestamp/randomness
+- **Key Management**: Uses existing admin/relay key pair
+- **Backward Compatible**: Standard mode still works
+- **Performance**: Only decrypt when needed (empty tags detection)
+
+### NIP-44 Library Integration
+The relay will need to integrate a NIP-44 encryption/decryption library:
+
+```c
+// Required NIP-44 functions
+char* nip44_encrypt(const char* plaintext, const char* sender_privkey, const char* recipient_pubkey);
+char* nip44_decrypt(const char* ciphertext, const char* recipient_privkey, const char* sender_pubkey);
+```
+

+- [ ] **Configuration discovery API** (list available config keys)
+- [ ] **Enhanced error messages** with encryption status
+- [ ] **Performance optimization** (caching, async decrypt)
+
+#### Phase 4: Schema Fixes (Critical)

 | `nip40_expiration_grace_period` | Grace period (seconds) | "300" | 0-86400 |
 
+## Web Admin Interface
+
+The relay includes a built-in web-based administration interface that provides a user-friendly way to manage your relay without command-line tools.
+
+### Accessing the Interface
+
+1. **Open your browser** and navigate to: `http://localhost:8888/api/`
+2. **Authenticate** using your Nostr identity (the admin interface uses NIP-42 authentication)
+3. **Manage configuration** through the web interface
+
+### Features
+
+- **Real-time Configuration**: View and edit all relay settings
+- **Database Statistics**: Monitor event counts, storage usage, and performance metrics
+- **Auth Rules Management**: Configure whitelist/blacklist rules for pubkeys
+- **Relay Connection Testing**: Verify WebSocket connectivity and NIP-11 information
+- **Event-Based Updates**: All changes are applied as signed Nostr events
+
+### Security Notes
+
+- The web interface requires NIP-42 authentication with your admin pubkey
+- All configuration changes are cryptographically signed
+- The interface serves embedded static files (no external dependencies)
+- CORS headers are included for proper browser operation
+
+### Browser Compatibility
+
+The admin interface works with modern browsers that support:
+- WebSocket connections
+- ES6 JavaScript features
+- Modern CSS Grid and Flexbox layouts
+
