+
+## Overview
+
+C-Relay uses an innovative **event-based administration system** where all configuration and management commands are sent as cryptographically signed Nostr events. This provides:
+
+- **Cryptographic security**: All commands must be signed with the admin private key
+- **Audit trail**: Complete history of all administrative actions
+- **Real-time updates**: Configuration changes applied instantly
+- **Standard protocol**: Uses Nostr events, no custom protocols
+- **NIP-44 encryption**: All admin commands and responses are encrypted
+
+### Key Concepts
+
+1. **Admin Keypair**: Generated on first startup, used to sign all admin commands
+2. **Relay Keypair**: The relay's identity on the Nostr network
+3. **Admin Events**: Kind 23456 events with NIP-44 encrypted commands
+4. **Response Events**: Kind 23457 events with NIP-44 encrypted responses
+5. **Event-Based Config**: All settings stored as events in the database
+
+## Authentication
+
+### Admin Private Key
+
+The admin private key is displayed **only once** during first startup:
+
+```
+========================================
+IMPORTANT: SAVE THIS ADMIN PRIVATE KEY
+========================================
+Admin Private Key: nsec1abc123...
+Admin Public Key: npub1def456...
+========================================
+```
+
+**Critical**: Save this key immediately. It cannot be recovered and is required for all administrative operations.
+
+### Secure Storage
+
+Store the admin private key securely:
+
+```bash
+# Environment variable
+export C_RELAY_ADMIN_KEY="nsec1abc123..."
+
+# Secure file
+echo "nsec1abc123..." > ~/.c-relay-admin
+chmod 600 ~/.c-relay-admin
+
+# Password manager (recommended)
+# Store in 1Password, Bitwarden, etc.
+```
+
+### Key Loss Recovery
+
+If you lose the admin private key:
+
+1. Stop the relay
+2. Delete the database file (`*.db`)
+3. Restart the relay (generates new keys)
+4. **Note**: This deletes all events and configuration
+
+## Admin API
+
+### Event Structure
+
+All admin commands use the same event structure with NIP-44 encrypted content.
+
+#### Admin Command Event (Kind 23456)
+
+```json
+{
+  "id": "computed_event_id",
+  "pubkey": "admin_public_key_hex",
+  "created_at": 1234567890,
+  "kind": 23456,
+  "content": "AqHBUgcM7dXFYLQuDVzGwMST1G8jtWYyVvYxXhVGEu4nAb4LVw...",
+  "tags": [
+    ["p", "relay_public_key_hex"]
+  ],
+  "sig": "event_signature"
+}
+```
+
+**Fields**:
+- `kind`: Must be `23456` for admin commands
+- `pubkey`: Admin public key (hex format)
+- `content`: NIP-44 encrypted JSON array containing the command
+- `tags`: Must include `["p", "relay_pubkey"]` tag
+- `sig`: Valid signature from admin private key
+
+#### Encrypted Content Format
+
+The `content` field contains a NIP-44 encrypted JSON array:
+
+```json
+["command_name", "param1", "param2", ...]
+```
+
+Examples:
+```json
+["config_query", "all"]
+["config_update", [{"key": "relay_name", "value": "My Relay", ...}]]
+["blacklist", "pubkey", "abc123..."]
+["auth_query", "all"]
+["sql_query", "SELECT * FROM events LIMIT 10"]
+```
+
+#### Admin Response Event (Kind 23457)
+
+```json
+{
+  "id": "response_event_id",
+  "pubkey": "relay_public_key_hex",
+  "created_at": 1234567890,
+  "kind": 23457,
+  "content": "BpKCVhfN8eYtRmPqSvWxZnMkL2gHjUiOp3rTyEwQaS5dFg...",
+  "tags": [
+    ["p", "admin_public_key_hex"],
+    ["e", "request_event_id"]
+  ],
+  "sig": "response_signature"
+}
+```
+
+**Fields**:
+- `kind`: Always `23457` for admin responses
+- `pubkey`: Relay public key (hex format)
+- `content`: NIP-44 encrypted JSON response object
+- `tags`: Includes `["p", "admin_pubkey"]` and optionally `["e", "request_id"]`
+- `sig`: Valid signature from relay private key

+
+## Real-time Monitoring
+
+C-Relay provides subscription-based real-time monitoring using ephemeral events (kind 24567).
+
+### Activation
+
+Subscribe to kind 24567 events to activate monitoring:
+
+```json
+["REQ", "monitoring-sub", {"kinds": [24567]}]
+```
+
+### Monitoring Event Types
+
+Subscribe to specific monitoring types using d-tag filters:
+
+```json
+["REQ", "event-kinds", {"kinds": [24567], "#d": ["event_kinds"]}]
+["REQ", "time-stats", {"kinds": [24567], "#d": ["time_stats"]}]
+["REQ", "top-pubkeys", {"kinds": [24567], "#d": ["top_pubkeys"]}]
+["REQ", "cpu-metrics", {"kinds": [24567], "#d": ["cpu_metrics"]}]
+```

+  ]
+}
+```
+

+  "last_24h": 234,
+  "last_7d": 1456,
+  "last_30d": 5432
+}
+```
+
+#### Top Publishers (`top_pubkeys`)
+
+```json
+{
+  "data_type": "top_pubkeys",
+  "timestamp": 1234567890,
+  "top_pubkeys": [
+    {"pubkey": "abc123...", "count": 1234, "percentage": 8.0},
+    {"pubkey": "def456...", "count": 987, "percentage": 6.4}
+  ]
+}
+```

+  "data_type": "cpu_metrics",
+  "timestamp": 1234567890,
+  "cpu_percent": 12.5,
+  "memory_mb": 45.2,
+  "uptime_seconds": 86400
+}
+```
+
+#### Active Subscriptions (`active_subscriptions`) - Admin Only
+
+```json
+{
+  "data_type": "active_subscriptions",
+  "timestamp": 1234567890,
+  "total_subscriptions": 156,
+  "subscriptions_by_client": [
+    {"client_id": "client1", "count": 12},
+    {"client_id": "client2", "count": 8}
+  ]
+}
+```
+
+### Configuration
+
+Control monitoring frequency:
+
+```json
+["config_update", [{
+  "key": "kind_24567_reporting_throttle_sec",
+  "value": "10",
+  "data_type": "integer",
+  "category": "monitoring"
+}]]
+```
+
+### Performance
+
+- Events are ephemeral (not stored)
+- Automatic activation/deactivation based on subscriptions
+- Throttling prevents excessive event generation
+- Minimal overhead when no clients monitoring
+
+## Direct Message Admin
+
+Control your relay by sending direct messages from any Nostr client.
+
+### Setup
+
+1. The relay has its own keypair (shown on startup)
+2. The relay knows the admin public key
+3. Send NIP-17 direct messages to the relay
+
+### Available Commands
+
+Send a DM containing any of these keywords:
+
+| Command | Aliases | Response |
+|---------|---------|----------|
+| Statistics | stats, statistics | Database statistics |
+| Configuration | config, configuration | Current configuration |
+
+### Example
+
+Using any Nostr client that supports NIP-17:
+
+1. Find the relay's public key (shown on startup)
+2. Send a DM: "stats"
+3. Receive a DM with current relay statistics
+
+### Response Format
+
+The relay responds with a NIP-17 DM containing:
+

+| `invalid_signature` | Event signature invalid | Check admin private key |
+| `unauthorized` | Wrong admin pubkey | Use correct admin key |
+| `invalid_command` | Unknown command | Check command format |
+| `validation_failed` | Invalid parameter value | Check parameter ranges |
+| `database_error` | Database operation failed | Check database integrity |
+| `timeout` | Query took too long | Simplify query or increase timeout |
+
+### Error Response Example
+
+```json
+{
+  "query_type": "config_update",
+  "status": "error",
+  "error": "field validation failed: invalid port number '99999' (must be 1-65535)",

+### Python Example
+
+```python

+client.connect()
+
+# Send admin command
+async def send_admin_command(command):
+    # Encrypt command
+    encrypted = nip44.encrypt(
+        keys.secret_key(),
+        relay_pubkey,

+    
+    # Publish
+    await client.send_event(event)
+    
+    # Wait for response
+    filter = Filter().kind(23457).pubkey(relay_pubkey).since(int(time.time()))
+    events = await client.get_events_of([filter], timeout=5)
+

+
+# Query configuration
+config = await send_admin_command(["config_query", "all"])
+print(config)
+```
+
+### Bash/curl Example
+
+```bash
+#!/bin/bash
+
+# Note: This is a simplified example. Real implementation requires:
+# - NIP-44 encryption
+# - Event signing
+# - WebSocket connection
+
+RELAY_URL="ws://localhost:8888"
+ADMIN_PRIVKEY="your_admin_privkey"
+RELAY_PUBKEY="relay_pubkey"
+
+# Use nostrtool or similar for proper event creation
+nostrtool event \

+# Relay
+
+I am releasing the code for the nostr relay that I wrote use myself. The code is free for anyone to use in any way that they wish.
+
+Some of the features of this relay are conventional, and some are unconventional.
+
+## The conventional
+
+This relay is written in C99 with a sqlite database.
+
+It implements the following NIPs.
+
+- [x] NIP-01: Basic protocol flow implementation
+- [x] NIP-09: Event deletion
+- [x] NIP-11: Relay information document
+- [x] NIP-13: Proof of Work
+- [x] NIP-15: End of Stored Events Notice
+- [x] NIP-20: Command Results
+- [x] NIP-33: Parameterized Replaceable Events
+- [x] NIP-40: Expiration Timestamp
+- [x] NIP-42: Authentication of clients to relays
+- [x] NIP-45: Counting results
+- [x] NIP-50: Keywords filter
+- [x] NIP-70: Protected Events
+
+## The unconventional
+
+### The binaries are fully self contained.
+
+It should just run in linux without having to worry about what you have on your system. I want to download and run. No docker. No dependency hell.
+
+I'm not bothering with other operating systems.
+
+### The relay is a full nostr citizen with it's own public and private keys.
+
+For example, you can see my relay's profile (wss://relay.laantungir.net) running here:
+
+[Primal link](https://primal.net/p/nprofile1qqswn2jsmm8lq8evas0v9vhqkdpn9nuujt90mtz60nqgsxndy66es4qjjnhr7)
+
+What this means in practice is that when you start the relay, it generates keys for itself, and for it's administrator (You can specify these if you wish)
+
+Now the program and the administrator can have verifed communication between the two, simply by using nostr events. For example, the administrator can send DMs to the relay, asking it's status, and changing it's configuration through any client that can handle nip17 DMs. The relay can also send notifications to the administrator about it's current status, or it can publish it's status on a regular schedule directly to NOSTR as kind-1 notes.
+
+Also included is a more standard administrative web front end. This front end communicates to the relay using an extensive api, which again is nostr events signed by the administrator. You can completely control the relay through signed nostr events.

+docker build -f Dockerfile.alpine-musl -t c-relay .

-**That's it!** Your relay is now running with zero configuration required. The event-based configuration system means you can adjust all settings through the web interface or admin API without editing config files.
-
-
-## 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"
-}
+# Run container
+docker run -d \
+  --name c-relay \
+  -p 8888:8888 \
+  -v /path/to/data:/data \
+  c-relay
 ```

-The `content` field contains a NIP-44 encrypted JSON array representing the command.
+### Cloud Deployment

-**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"
-}]
+Quick deployment scripts for popular cloud providers:
+
+```bash
+# AWS, GCP, DigitalOcean, etc.
+sudo examples/deployment/simple-vps/deploy.sh
 ```

-The `content` field contains a NIP-44 encrypted JSON response object.
+See [`docs/deployment_guide.md`](docs/deployment_guide.md) for detailed deployment instructions.

-### Admin Commands

-##  Direct Messaging Admin System
-
-In addition to the above admin API, c-relay allows the administrator to direct message the relay to get information or control some settings. As long as the administrator is signed in with any nostr client that allows sending nip-17 direct messages (DMs), they can control the relay.
-
-The is possible because the relay is a full nostr citizen with it's own private and public key, and it knows the administrator's public key.
-
-
-
-**Available DM commands**
-
-The intent is not to be strict in the formatting of the DM. So for example if the relay receives any DM from the administrator with the words "stats" or "statistics" in it, it will respond to the administrator with a reply DM with the current relay statistics.

+# Real-Time Traffic Monitoring Commands (Direct Server Use)
+
+Copy and paste these commands directly on your server.
+
+## Quick Status Checks
+
+### See IPs visiting in the last few minutes:
+```bash
+sudo tail -500 /var/log/nginx/access.log | awk '{print $1}' | sort | uniq -c | sort -rn | head -20
+```
+
+### See what status codes they're getting:
+```bash
+sudo tail -500 /var/log/nginx/access.log | awk '{print $1, $9}' | grep '216.73.216.38'
+```
+
+### Count status codes (200 vs 403):
+```bash
+sudo tail -500 /var/log/nginx/access.log | awk '{print $9}' | sort | uniq -c
+```
+
+## Real-Time Monitoring
+
+### Watch live traffic (updates every 2 seconds):
+```bash
+watch -n 2 'sudo tail -200 /var/log/nginx/access.log | awk "{print \$1}" | sort | uniq -c | sort -rn | head -15'
+```
+
+### See live log entries as they happen:
+```bash
+sudo tail -f /var/log/nginx/access.log
+```
+
+### Live GoAccess dashboard:
+```bash
+sudo tail -f /var/log/nginx/access.log | goaccess -
+```
+
+## Active Connections
+
+### See who's connected RIGHT NOW:
+```bash
+sudo netstat -tn | grep ':443' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -rn
+```
+
+### Alternative (using ss command):
+```bash
+sudo ss -tn | grep ':443' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -rn
+```
+
+## Detailed Analysis
+
+### Last 100 requests with timestamps:
+```bash
+sudo tail -100 /var/log/nginx/access.log | awk '{print $4, $1}' | sed 's/\[//'
+```
+
+### See what blocked IPs are trying to access:
+```bash
+sudo tail -500 /var/log/nginx/access.log | grep '216.73.216.38' | awk '{print $7}' | head -10
+```
+
+### Show all 403 (blocked) requests:
+```bash
+sudo tail -500 /var/log/nginx/access.log | awk '$9==403 {print $1}' | sort | uniq -c | sort -rn
+```
+
+### Show all successful (200) requests:
+```bash
+sudo tail -500 /var/log/nginx/access.log | awk '$9==200 {print $1}' | sort | uniq -c | sort -rn | head -10
+```
+
+## Comprehensive Monitoring Script
+
+### Create a monitoring script:
+```bash
+cat > /tmp/monitor-traffic.sh << 'EOF'
+#!/bin/bash
+echo "=== Traffic in last 5 minutes ==="
+echo "Time: $(date)"
+echo ""
+echo "Top IPs:"
+sudo tail -1000 /var/log/nginx/access.log | awk '{print $1}' | sort | uniq -c | sort -rn | head -10
+echo ""
+echo "Blocked IPs (403 errors):"
+sudo tail -1000 /var/log/nginx/access.log | awk '$9==403 {print $1}' | sort | uniq -c | sort -rn
+echo ""
+echo "Successful requests (200):"
+sudo tail -1000 /var/log/nginx/access.log | awk '$9==200 {print $1}' | sort | uniq -c | sort -rn | head -5
+echo ""
+echo "Status Code Summary:"
+sudo tail -1000 /var/log/nginx/access.log | awk '{print $9}' | sort | uniq -c | sort -rn
+EOF
+chmod +x /tmp/monitor-traffic.sh
+```
+
+### Run the monitoring script:
+```bash
+/tmp/monitor-traffic.sh
+```
+
+## Auto-Refreshing Dashboard
+
+### Live dashboard (refreshes every 5 seconds):
+```bash
+watch -n 5 'echo "=== Last 5 minutes ==="
+date
+echo ""
+echo "Top IPs:"
+sudo tail -1000 /var/log/nginx/access.log | awk "{print \$1}" | sort | uniq -c | sort -rn | head -10
+echo ""
+echo "Status Codes:"
+sudo tail -1000 /var/log/nginx/access.log | awk "{print \$9}" | sort | uniq -c | sort -rn'
+```
+
+Press `Ctrl+C` to exit.
+
+## GoAccess HTML Report (Live Updating)
+
+### Generate live HTML report:
+```bash
+sudo goaccess /var/log/nginx/access.log -o /var/www/html/live-stats.html --real-time-html --daemonize
+```
+
+Then visit: https://git.laantungir.net/live-stats.html
+
+### Stop the live report:
+```bash
+sudo pkill -f "goaccess.*live-stats"
+```
+
+## Filter by Time
+
+### Get timestamp from 5 minutes ago:
+```bash
+date -d '5 minutes ago' '+%d/%b/%Y:%H:%M'
+```
+
+### Analyze only recent logs (replace timestamp):
+```bash
+sudo awk '/01\/Feb\/2026:19:09/,0' /var/log/nginx/access.log | goaccess -
+```
+
+## Check Gitea CPU
+
+### Current CPU usage:
+```bash
+ps aux | grep gitea | grep -v grep
+```
+
+### Watch CPU in real-time:
+```bash
+watch -n 2 'ps aux | grep gitea | grep -v grep'
+```
+
+## Most Useful Command for Quick Check
+
+This one-liner shows everything you need:
+```bash
+
+echo "=== Quick Status ===" && \
+echo "Time: $(date)" && \
+echo "" && \
+echo "Top 10 IPs (last 1000 requests):" && \
+sudo tail -1000 /var/log/nginx/access.log | awk '{print $1}' | sort | uniq -c | sort -rn | head -10 && \
+echo "" && \
+echo "Status Codes:" && \
+sudo tail -1000 /var/log/nginx/access.log | awk '{print $9}' | sort | uniq -c && \
+echo "" && \
+echo "Gitea CPU:" && \
+ps aux | grep gitea | grep -v grep
+```

+# Static MUSL Build Guide for C Programs
+
+## Overview
+
+This guide explains how to build truly portable static binaries using Alpine Linux and MUSL libc. These binaries have **zero runtime dependencies** and work on any Linux distribution without modification.
+
+This guide is specifically tailored for C programs that use:
+- **nostr_core_lib** - Nostr protocol implementation
+- **nostr_login_lite** - Nostr authentication library
+- Common dependencies: libwebsockets, OpenSSL, SQLite, curl, secp256k1
+
+## Why MUSL Static Binaries?
+
+### Advantages Over glibc
+
+| Feature | MUSL Static | glibc Static | glibc Dynamic |
+|---------|-------------|--------------|---------------|
+| **Portability** | ✓ Any Linux | ⚠ glibc only | ✗ Requires matching libs |
+| **Binary Size** | ~7-10 MB | ~12-15 MB | ~2-3 MB |
+| **Dependencies** | None | NSS libs | Many system libs |
+| **Deployment** | Single file | Single file + NSS | Binary + libraries |
+| **Compatibility** | Universal | glibc version issues | Library version hell |
+
+### Key Benefits
+
+1. **True Portability**: Works on Alpine, Ubuntu, Debian, CentOS, Arch, etc.
+2. **No Library Hell**: No `GLIBC_2.XX not found` errors
+3. **Simple Deployment**: Just copy one file
+4. **Reproducible Builds**: Same Docker image = same binary
+5. **Security**: No dependency on system libraries with vulnerabilities
+
+## Quick Start
+
+### Prerequisites
+
+- Docker installed and running
+- Your C project with source code
+- Internet connection for downloading dependencies
+
+### Basic Build Process
+
+```bash
+# 1. Copy the Dockerfile template (see below)
+cp /path/to/c-relay/Dockerfile.alpine-musl ./Dockerfile.static
+
+# 2. Customize for your project (see Customization section)
+vim Dockerfile.static
+
+# 3. Build the static binary
+docker build --platform linux/amd64 -f Dockerfile.static -t my-app-builder .
+
+# 4. Extract the binary
+docker create --name temp-container my-app-builder
+docker cp temp-container:/build/my_app_static ./my_app_static
+docker rm temp-container
+
+# 5. Verify it's static
+ldd ./my_app_static  # Should show "not a dynamic executable"
+```
+
+## Dockerfile Template
+
+Here's a complete Dockerfile template you can customize for your project:
+
+```dockerfile

+
+# Output stage - just the binary
+FROM scratch AS output
+COPY --from=builder /build/my_app_static /my_app_static
+```
+
+## Customization Guide
+
+### 1. Adjust Dependencies
+
+**Add dependencies** by modifying the `apk add` section:
+
+```dockerfile
+RUN apk add --no-cache \
+    build-base \
+    musl-dev \
+    # Add your dependencies here:
+    libpng-dev \
+    libpng-static \
+    libjpeg-turbo-dev \
+    libjpeg-turbo-static
+```
+
+**Remove unused dependencies** to speed up builds:
+- Remove `libwebsockets` section if you don't need WebSocket support
+- Remove `sqlite` if you don't use databases
+- Remove `curl` if you don't make HTTP requests
+
+### 2. Configure nostr_core_lib NIPs
+
+Specify which NIPs your application needs:
+
+```bash
+./build.sh --nips=1,6,19  # Minimal: Basic protocol, keys, bech32
+./build.sh --nips=1,6,13,17,19,44,59  # Full: All common NIPs
+./build.sh --nips=all  # Everything available
+```
+
+**Common NIP combinations:**
+- **Basic client**: `1,6,19` (events, keys, bech32)
+- **With encryption**: `1,6,19,44` (add modern encryption)
+- **With DMs**: `1,6,17,19,44,59` (add private messages)
+- **Relay/server**: `1,6,13,17,19,42,44,59` (add PoW, auth)
+
+### 3. Modify Compilation Flags
+
+**For your application:**
+
+```dockerfile
+RUN gcc -static -O2 -Wall -Wextra -std=c99 \
+    -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 \  # REQUIRED for MUSL
+    -I. -Inostr_core_lib \                    # Include paths
+    src/*.c \                                  # Your source files
+    -o /build/my_app_static \                 # Output binary
+    nostr_core_lib/libnostr_core_x64.a \     # Nostr library
+    -lwebsockets -lssl -lcrypto \             # Link libraries
+    -lsqlite3 -lsecp256k1 -lcurl \
+    -lz -lpthread -lm -ldl
+```
+
+**Debug build** (with symbols, no optimization):
+
+```dockerfile
+RUN gcc -static -g -O0 -DDEBUG \
+    -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 \
+    # ... rest of flags
+```
+
+### 4. Multi-Architecture Support
+
+Build for different architectures:
+
+```bash
+# x86_64 (Intel/AMD)
+docker build --platform linux/amd64 -f Dockerfile.static -t my-app-x86 .
+
+# ARM64 (Apple Silicon, Raspberry Pi 4+)
+docker build --platform linux/arm64 -f Dockerfile.static -t my-app-arm64 .
+```
+
+## Build Script Template
+
+Create a `build_static.sh` script for convenience:
+
+```bash
+#!/bin/bash
+set -e
+
+SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+BUILD_DIR="$SCRIPT_DIR/build"
+DOCKERFILE="$SCRIPT_DIR/Dockerfile.static"
+
+# Detect architecture
+ARCH=$(uname -m)
+case "$ARCH" in
+    x86_64)
+        PLATFORM="linux/amd64"
+        OUTPUT_NAME="my_app_static_x86_64"
+        ;;
+    aarch64|arm64)
+        PLATFORM="linux/arm64"
+        OUTPUT_NAME="my_app_static_arm64"
+        ;;
+    *)
+        echo "Unknown architecture: $ARCH"
+        exit 1
+        ;;
+esac
+
+echo "Building for platform: $PLATFORM"
+mkdir -p "$BUILD_DIR"
+
+# Build Docker image
+docker build \
+    --platform "$PLATFORM" \
+    -f "$DOCKERFILE" \
+    -t my-app-builder:latest \
+    --progress=plain \
+    .
+
+# Extract binary
+CONTAINER_ID=$(docker create my-app-builder:latest)
+docker cp "$CONTAINER_ID:/build/my_app_static" "$BUILD_DIR/$OUTPUT_NAME"
+docker rm "$CONTAINER_ID"
+
+chmod +x "$BUILD_DIR/$OUTPUT_NAME"
+
+echo "✓ Build complete: $BUILD_DIR/$OUTPUT_NAME"
+echo "✓ Size: $(du -h "$BUILD_DIR/$OUTPUT_NAME" | cut -f1)"
+
+# Verify
+if ldd "$BUILD_DIR/$OUTPUT_NAME" 2>&1 | grep -q "not a dynamic executable"; then
+    echo "✓ Binary is fully static"
+else
+    echo "⚠ Warning: Binary may have dynamic dependencies"
+fi
+```
+
+Make it executable:
+
+```bash
+chmod +x build_static.sh
+./build_static.sh
+```
+
+## Common Issues and Solutions
+
+### Issue 1: Fortification Errors
+
+**Error:**
+```
+undefined reference to '__snprintf_chk'
+undefined reference to '__fprintf_chk'
+```
+
+**Cause**: GCC's `-O2` enables fortification by default, which uses glibc-specific functions.
+
+**Solution**: Add these flags to **all** compilation commands:
+```bash
+-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0
+```
+
+This must be applied to:
+1. nostr_core_lib build.sh
+2. Your application compilation
+3. Any other libraries you build
+
+### Issue 2: Missing Symbols from nostr_core_lib
+
+**Error:**
+```
+undefined reference to 'nostr_create_event'
+undefined reference to 'nostr_sign_event'
+```
+
+**Cause**: Required NIPs not included in nostr_core_lib build.
+
+**Solution**: Add missing NIPs:
+```bash
+./build.sh --nips=1,6,19  # Add the NIPs you need
+```
+
+### Issue 3: Docker Permission Denied
+
+**Error:**
+```
+permission denied while trying to connect to the Docker daemon socket
+```
+
+**Solution**:
+```bash
+sudo usermod -aG docker $USER
+newgrp docker  # Or logout and login
+```
+
+### Issue 4: Binary Won't Run on Target System
+
+**Checks**:
+```bash
+# 1. Verify it's static
+ldd my_app_static  # Should show "not a dynamic executable"
+
+# 2. Check architecture
+file my_app_static  # Should match target system
+
+# 3. Test on different distributions
+docker run --rm -v $(pwd):/app alpine:latest /app/my_app_static --version
+docker run --rm -v $(pwd):/app ubuntu:latest /app/my_app_static --version
+```
+
+## Project Structure Example
+
+Organize your project for easy static builds:
+
+```
+my-nostr-app/
+├── src/
+│   ├── main.c
+│   ├── handlers.c
+│   └── utils.c
+├── nostr_core_lib/          # Git submodule
+├── nostr_login_lite/        # Git submodule (if used)
+├── Dockerfile.static        # Static build Dockerfile
+├── build_static.sh          # Build script
+├── Makefile                 # Regular build
+└── README.md
+```
+
+### Makefile Integration
+
+Add static build targets to your Makefile:
+
+```makefile
+# Regular dynamic build
+all: my_app
+
+my_app: src/*.c
+	gcc -O2 src/*.c -o my_app \
+		nostr_core_lib/libnostr_core_x64.a \
+		-lssl -lcrypto -lsecp256k1 -lz -lpthread -lm
+
+# Static MUSL build via Docker
+static:
+	./build_static.sh
+
+# Clean
+clean:
+	rm -f my_app build/my_app_static_*
+
+.PHONY: all static clean
+```
+
+## Deployment
+
+### Single Binary Deployment
+
+```bash
+# Copy to server
+scp build/my_app_static_x86_64 user@server:/opt/my-app/
+
+# Run (no dependencies needed!)
+ssh user@server
+/opt/my-app/my_app_static_x86_64
+```
+
+### SystemD Service
+
+```ini
+[Unit]
+Description=My Nostr Application
+After=network.target
+
+[Service]
+Type=simple
+User=myapp
+WorkingDirectory=/opt/my-app
+ExecStart=/opt/my-app/my_app_static_x86_64
+Restart=always
+RestartSec=5
+
+[Install]
+WantedBy=multi-user.target
+```
+
+### Docker Container (Minimal)
+
+```dockerfile
+FROM scratch
+COPY my_app_static_x86_64 /app
+ENTRYPOINT ["/app"]
+```
+
+Build and run:
+```bash
+docker build -t my-app:latest .
+docker run --rm my-app:latest --help
+```
+
+## Reusing c-relay Files
+
+You can directly copy these files from c-relay:
+
+### 1. Dockerfile.alpine-musl
+```bash
+cp /path/to/c-relay/Dockerfile.alpine-musl ./Dockerfile.static
+```
+
+Then customize:
+- Change binary name (line 125)
+- Adjust source files (line 122-124)
+- Modify include paths (line 120-121)
+
+### 2. build_static.sh
+```bash
+cp /path/to/c-relay/build_static.sh ./
+```
+
+Then customize:
+- Change `OUTPUT_NAME` variable (lines 66, 70)
+- Update Docker image name (line 98)
+- Modify verification commands (lines 180-184)
+
+### 3. .dockerignore (Optional)
+```bash
+cp /path/to/c-relay/.dockerignore ./
+```
+
+Helps speed up Docker builds by excluding unnecessary files.
+
+## Best Practices
+
+1. **Version Control**: Commit your Dockerfile and build script
+2. **Tag Builds**: Include git commit hash in binary version
+3. **Test Thoroughly**: Verify on multiple distributions
+4. **Document Dependencies**: List required NIPs and libraries
+5. **Automate**: Use CI/CD to build on every commit
+6. **Archive Binaries**: Keep old versions for rollback
+
+## Performance Comparison
+
+| Metric | MUSL Static | glibc Dynamic |
+|--------|-------------|---------------|
+| Binary Size | 7-10 MB | 2-3 MB + libs |
+| Startup Time | ~50ms | ~40ms |
+| Memory Usage | Similar | Similar |
+| Portability | ✓ Universal | ✗ System-dependent |
+| Deployment | Single file | Binary + libraries |

+## Example: Minimal Nostr Client
+
+Here's a complete example of building a minimal Nostr client:
+
+```c
+// minimal_client.c
+#include "nostr_core/nostr_core.h"
+#include <stdio.h>
+
+int main() {
+    // Generate keypair
+    char nsec[64], npub[64];
+    nostr_generate_keypair(nsec, npub);
+    
+    printf("Generated keypair:\n");
+    printf("Private key (nsec): %s\n", nsec);
+    printf("Public key (npub): %s\n", npub);

+## Conclusion
+
+Static MUSL binaries provide the best portability for C applications. While they're slightly larger than dynamic binaries, the benefits of zero dependencies and universal compatibility make them ideal for:
+
+- Server deployments across different Linux distributions
+- Embedded systems and IoT devices
+- Docker containers (FROM scratch)
+- Distribution to users without dependency management
+- Long-term archival and reproducibility
+
+Follow this guide to create portable, self-contained binaries for your Nostr applications!

+# Agent Browser Testing Guide for C-Relay
+
+This document explains how to use the `agent-browser` CLI tool to test the c-relay admin web UI from an AI agent context (no physical display required).
+
+## Prerequisites
+
+- **agent-browser** installed globally: `npm install -g agent-browser`
+- Binary location: `/home/user/.nvm/versions/node/v24.14.1/bin/agent-browser`
+- The relay must be running locally (default port 8888)
+- Test keys configured in `.test_keys`
+
+## Starting the Relay for Local Testing
+
+```bash
+./make_and_restart_relay.sh -t
+```
+
+This reads `.test_keys` and starts the relay with:
+- `ADMIN_PUBKEY` — the hex public key of the admin account
+- `ADMIN_PRIVKEY` — the hex secret key (used for browser login, not by the relay itself)
+- `SERVER_PRIVKEY` — the relay's own private key
+
+## Key URLs
+
+| URL | Purpose |
+|-----|---------|
+| `http://127.0.0.1:8888/api/index.html` | Admin web UI (the correct entry point) |
+| `http://127.0.0.1:8888/` | Returns 406 without NIP-11 Accept header — **do not use for browser testing** |
+| `http://127.0.0.1:8888/` with `Accept: application/nostr+json` | NIP-11 relay info JSON |
+
+**Important:** The root URL `/` is a WebSocket/NIP-11 endpoint, not an HTML page. Always use `/api/index.html` for browser testing.
+
+## Admin Login Credentials
+
+The admin nsec for the current `.test_keys` configuration:
+
+```
+nsec: nsec1zkn0hlt4jvcvn9yt5p7ea4m7f82pf3ph0gj3d4rlcz4s64x5z86satv9qm
+hex:  15a6fbfd759330c9948ba07d9ed77e49d414c4377a2516d47fc0ab0d54d411f5
+npub: npub1tlyzk6slzt8d989f4pn3synk98fea64ea3jmrdc7dtd0kw8uxlas9a9fwr
+hex pubkey: 5fc82b6a1f12ced29ca9a86718127629d39eeab9ec65b1b71e6adafb38fc37fb
+```
+
+## Complete Login Flow with agent-browser
+
+### Step 1: Open the admin UI
+
+```bash
+agent-browser open http://127.0.0.1:8888/api/index.html
+agent-browser wait --load networkidle
+```
+
+### Step 2: Take an interactive snapshot to see what is on screen
+
+```bash
+agent-browser snapshot -i
+```
+
+You will see a login modal with buttons like:
+- `"Browser Extension"` — skip this
+- `"Local Key"` — **use this one**
+- `"Seed Phrase"` — skip
+- `"Nostr Connect"` — skip
+- `"Read Only"` — skip
+
+### Step 3: Click "Local Key"
+
+```bash
+agent-browser click @e15
+```
+
+(The ref number may vary — use the ref from the snapshot output for the "Local Key" button.)
+
+After clicking, a text input appears asking for the secret key.
+
+### Step 4: Enter the admin nsec
+
+```bash
+agent-browser fill @e14 "nsec1zkn0hlt4jvcvn9yt5p7ea4m7f82pf3ph0gj3d4rlcz4s64x5z86satv9qm"
+```
+
+(Use the ref from the snapshot for the textbox element.)
+
+### Step 5: Click "Import Key"
+
+```bash
+agent-browser snapshot -i
+```
+
+Check the snapshot — the "Import Key" button should now be enabled. Click it:
+
+```bash
+agent-browser click @e15
+```
+
+### Step 6: Click "Continue" on the success screen
+
+After import, a success screen appears with "Continue" button:
+
+```bash
+agent-browser wait 800
+agent-browser snapshot -i
+agent-browser click @e19
+```
+
+(Use the ref from the snapshot for the "Continue" button.)
+
+### Step 7: Wait for admin UI to load
+
+```bash
+agent-browser wait 5000
+agent-browser snapshot -i
+```
+
+You should now see the admin dashboard with:
+- Statistics table (Database Size, Total Events, PID, etc.)
+- Navigation buttons (Statistics, Subscriptions, Configuration, Authorization, etc.)
+- Admin profile area showing "admin" label
+
+## Navigating Admin Sections
+
+After login, use the sidebar navigation buttons:
+
+```bash
+# View configuration
+agent-browser click @e8    # Configuration button ref
+
+# View authorization rules
+agent-browser click @e9    # Authorization button ref
+
+# View statistics
+agent-browser click @e6    # Statistics button ref
+
+# Always snapshot after navigation to see results
+agent-browser wait 2500
+agent-browser snapshot -i
+```
+
+## Checking for Errors
+
+```bash
+# View browser console logs
+agent-browser console
+
+# View JavaScript errors
+agent-browser errors
+
+# View relay server logs
+tail -n 100 relay.log
+```
+
+## Chained Command Example (Full Login in One Shot)
+
+```bash
+agent-browser open http://127.0.0.1:8888/api/index.html && \
+agent-browser wait --load networkidle && \
+agent-browser snapshot -i
+```
+
+Then use refs from the snapshot to complete login steps.
+
+## Tips for AI Agents
+
+1. **Always use `/api/index.html`** — never the root URL
+2. **Use `snapshot -i`** after every action to see the current interactive elements and their refs
+3. **Refs change** between snapshots — always re-snapshot before clicking
+4. **Wait after clicks** — use `agent-browser wait 2000` (milliseconds) between actions that trigger async operations
+5. **The login flow has 3 screens**: method selection → key input → success confirmation
+6. **Console logs are cumulative** — they show all logs since page load, which is useful for debugging admin API responses
+7. **The relay log** at `relay.log` shows server-side processing of admin commands
+8. **Command chaining** with `&&` works — the browser daemon persists between commands
+
+## Verifying Admin API is Working
+
+After login, the statistics page should show populated data:
+- Database Size (e.g., "4 KB")
+- Process ID (the relay PID)
+- WebSocket Connections count
+- Memory Usage
+
+If these show "-" or "Loading...", check:
+1. `relay.log` for errors
+2. `agent-browser console` for JavaScript errors
+3. `agent-browser errors` for page-level errors
+
+## Closing the Browser
+
+```bash
+agent-browser close --all
+```

+# NIP-59 Timestamp Configuration Implementation Plan
+
+## Overview
+Add configurable timestamp randomization for NIP-59 gift wraps to improve compatibility with Nostr apps that don't implement timestamp randomization.
+
+## Problem Statement
+The NIP-59 protocol specifies that timestamps on gift wraps should have randomness to prevent time-analysis attacks. However, some Nostr platforms don't implement this, causing compatibility issues with direct messaging (NIP-17).
+
+## Solution
+Add a configuration parameter `nip59_timestamp_max_delay_sec` that controls the maximum random delay applied to timestamps:
+- **Value = 0**: Use current timestamp (no randomization) for maximum compatibility
+- **Value > 0**: Use random timestamp between now and N seconds ago
+- **Default = 0**: Maximum compatibility mode (no randomization)
+
+## Implementation Approach: Option B (Direct Parameter Addition)
+We chose Option B because:
+1. Explicit and stateless - value flows through call chain
+2. Thread-safe by design
+3. No global state needed in nostr_core_lib
+4. DMs are sent rarely, so database query per call is acceptable
+
+---
+
+## Detailed Implementation Steps
+
+### Phase 1: Configuration Setup in c-relay
+
+#### 1.1 Add Configuration Parameter
+**File:** `src/default_config_event.h`
+**Location:** Line 82 (after `trust_proxy_headers`)
+
+```c
+// NIP-59 Gift Wrap Timestamp Configuration
+{"nip59_timestamp_max_delay_sec", "0"}  // Default: 0 (no randomization for compatibility)
+```
+
+**Rationale:**
+- Default of 0 seconds (no randomization) for maximum compatibility
+- Placed after proxy settings, before closing brace
+- Follows existing naming convention
+
+#### 1.2 Add Configuration Validation
+**File:** `src/config.c`
+**Function:** `validate_config_field()` (around line 923)
+
+Add validation case:
+```c
+else if (strcmp(key, "nip59_timestamp_max_delay_sec") == 0) {
+    long value = strtol(value_str, NULL, 10);
+    if (value < 0 || value > 604800) {  // Max 7 days
+        snprintf(error_msg, error_size, 
+                 "nip59_timestamp_max_delay_sec must be between 0 and 604800 (7 days)");
+        return -1;
+    }
+}
+```
+
+**Rationale:**
+- 0 = no randomization (compatibility mode)
+- 604800 = 7 days maximum (reasonable upper bound)
+- Prevents negative values or excessive delays
+
+---
+
+### Phase 2: Modify nostr_core_lib Functions
+
+#### 2.1 Update random_past_timestamp() Function
+**File:** `nostr_core_lib/nostr_core/nip059.c`
+**Current Location:** Lines 31-36
+
+**Current Code:**
+```c
+static time_t random_past_timestamp(void) {
+    time_t now = time(NULL);
+    // Random time up to 2 days (172800 seconds) in the past
+    long random_offset = (long)(rand() % 172800);
+    return now - random_offset;
+}
+```
+
+**New Code:**
+```c
+static time_t random_past_timestamp(long max_delay_sec) {
+    time_t now = time(NULL);
+    
+    // If max_delay_sec is 0, return current timestamp (no randomization)
+    if (max_delay_sec == 0) {
+        return now;
+    }
+    
+    // Random time up to max_delay_sec in the past
+    long random_offset = (long)(rand() % max_delay_sec);
+    return now - random_offset;
+}
+```
+
+**Changes:**
+- Add `long max_delay_sec` parameter
+- Handle special case: `max_delay_sec == 0` returns current time
+- Use `max_delay_sec` instead of hardcoded 172800
+
+#### 2.2 Update nostr_nip59_create_seal() Function
+**File:** `nostr_core_lib/nostr_core/nip059.c`
+**Current Location:** Lines 144-215

+**Function Signature Change:**
+```c
+// OLD:

+```
+
+**Code Change at Line 181:**
+```c
+// OLD:
+time_t seal_time = random_past_timestamp();
+
+// NEW:
+time_t seal_time = random_past_timestamp(max_delay_sec);
+```
+
+#### 2.3 Update nostr_nip59_create_gift_wrap() Function
+**File:** `nostr_core_lib/nostr_core/nip059.c`
+**Current Location:** Lines 220-323
+
+**Function Signature Change:**

+```
+
+**Code Change at Line 275:**
+```c
+// OLD:
+time_t wrap_time = random_past_timestamp();
+
+// NEW:
+time_t wrap_time = random_past_timestamp(max_delay_sec);
+```
+
+#### 2.4 Update nip059.h Header
+**File:** `nostr_core_lib/nostr_core/nip059.h`
+**Locations:** Lines 38-39 and 48
+
+**Update Function Declarations:**

+```
+
+**Note:** Both files already include `config.h`, so `get_config_int()` is available.
+
+---
+
+## Testing Plan
+
+### Test Case 1: No Randomization (Compatibility Mode)
+**Configuration:** `nip59_timestamp_max_delay_sec = 0`
+
+**Expected Behavior:**
+- Gift wrap timestamps should equal current time
+- Seal timestamps should equal current time
+- No random delay applied
+
+**Test Command:**
+```bash
+# Set config via admin API
+# Send test DM
+# Verify timestamps are current (within 1 second of send time)
+```
+
+### Test Case 2: Custom Delay
+**Configuration:** `nip59_timestamp_max_delay_sec = 1000`
+
+**Expected Behavior:**
+- Gift wrap timestamps should be between now and 1000 seconds ago
+- Seal timestamps should be between now and 1000 seconds ago
+- Random delay applied within specified range
+
+**Test Command:**
+```bash
+# Set config via admin API
+# Send test DM
+# Verify timestamps are in past but within 1000 seconds
+```
+
+### Test Case 3: Default Behavior
+**Configuration:** `nip59_timestamp_max_delay_sec = 0` (default)
+
+**Expected Behavior:**
+- Gift wrap timestamps should equal current time
+- Seal timestamps should equal current time
+- No randomization (maximum compatibility)
+
+**Test Command:**
+```bash
+# Use default config
+# Send test DM
+# Verify timestamps are current (within 1 second of send time)
+```
+
+### Test Case 4: Configuration Validation
+**Test Invalid Values:**
+- Negative value: Should be rejected
+- Value > 604800: Should be rejected
+- Valid boundary values (0, 604800): Should be accepted
+
+### Test Case 5: Interoperability
+**Test with Other Nostr Clients:**
+- Send DM with `max_delay_sec = 0` to clients that don't randomize
+- Send DM with `max_delay_sec = 172800` to clients that do randomize
+- Verify both scenarios work correctly
+
+---
+
+## Documentation Updates
+
+### Update docs/configuration_guide.md
+
+Add new section:
+
+```markdown
+### NIP-59 Gift Wrap Timestamp Configuration
+
+#### nip59_timestamp_max_delay_sec
+- **Type:** Integer
+- **Default:** 0 (no randomization)
+- **Range:** 0 to 604800 (7 days)
+- **Description:** Controls timestamp randomization for NIP-59 gift wraps
+
+The NIP-59 protocol recommends randomizing timestamps on gift wraps to prevent
+time-analysis attacks. However, some Nostr platforms don't implement this,
+causing compatibility issues.
+
+**Values:**
+- `0` (default): No randomization - uses current timestamp (maximum compatibility)
+- `1-604800`: Random timestamp between now and N seconds ago
+
+**Use Cases:**
+- Keep default `0` for maximum compatibility with clients that don't randomize
+- Set to `172800` for privacy per NIP-59 specification (2 days randomization)
+- Set to custom value (e.g., `3600`) for 1-hour randomization window
+
+**Example:**
+```json
+["nip59_timestamp_max_delay_sec", "0"]  // Default: compatibility mode
+["nip59_timestamp_max_delay_sec", "3600"]  // 1 hour randomization
+["nip59_timestamp_max_delay_sec", "172800"]  // 2 days randomization
+```
+```
+

+2. Revert c-relay changes
+3. Configuration parameter will be ignored if not used
+4. Default behavior (0) provides maximum compatibility
+
+---
+
+## Notes
+
+- The configuration is read on each DM send, allowing runtime changes
+- No restart required when changing `nip59_timestamp_max_delay_sec`
+- Thread-safe by design (no global state)
+- Default value of 0 provides maximum compatibility with other Nostr clients
+- Can be changed to 172800 or other values for NIP-59 privacy features

+# Subscription Cleanup - Simplified Design
+
+## Problem Summary
+
+The c-relay Nostr relay experienced severe performance degradation (90-100% CPU) due to subscription accumulation in the database. Investigation revealed **323,644 orphaned subscriptions** that were never properly closed when WebSocket connections dropped.
+
+## Solution: Two-Component Approach
+
+This simplified design focuses on two pragmatic solutions that align with Nostr's stateless design:
+
+1. **Startup Cleanup**: Close all subscriptions on relay restart
+2. **Connection Age Limit**: Disconnect clients after a configurable time period
+
+Both solutions force clients to reconnect and re-establish subscriptions, which is standard Nostr behavior.
+
+---
+
+## Component 1: Startup Cleanup
+
+### Purpose
+Ensure clean state on every relay restart by closing all subscriptions in the database.
+
+### Implementation
+
+**File:** [`src/subscriptions.c`](src/subscriptions.c)
+
+**New Function:**
+```c
+void cleanup_all_subscriptions_on_startup(void) {
+    if (!g_db) {
+        DEBUG_ERROR("Database not initialized for startup cleanup");
+        return;
+    }
+    
+    DEBUG_LOG("Startup cleanup: Marking all active subscriptions as disconnected");
+    
+    // Mark all 'created' subscriptions as disconnected
+    const char* update_sql =
+        "UPDATE subscriptions "
+        "SET ended_at = strftime('%s', 'now') "
+        "WHERE event_type = 'created' AND ended_at IS NULL";
+    
+    sqlite3_stmt* stmt;
+    int rc = sqlite3_prepare_v2(g_db, update_sql, -1, &stmt, NULL);
+    if (rc != SQLITE_OK) {
+        DEBUG_ERROR("Failed to prepare startup cleanup query: %s", sqlite3_errmsg(g_db));
+        return;
+    }
+    
+    rc = sqlite3_step(stmt);
+    int updated_count = sqlite3_changes(g_db);
+    sqlite3_finalize(stmt);
+    
+    if (updated_count > 0) {
+        // Log a single 'disconnected' event for the startup cleanup
+        const char* insert_sql =
+            "INSERT INTO subscriptions (subscription_id, wsi_pointer, client_ip, event_type) "
+            "VALUES ('startup_cleanup', '', 'system', 'disconnected')";
+        
+        rc = sqlite3_prepare_v2(g_db, insert_sql, -1, &stmt, NULL);
+        if (rc == SQLITE_OK) {
+            sqlite3_step(stmt);
+            sqlite3_finalize(stmt);
+        }
+        
+        DEBUG_LOG("Startup cleanup: Marked %d subscriptions as disconnected", updated_count);
+    } else {
+        DEBUG_LOG("Startup cleanup: No active subscriptions found");
+    }
+}
+```
+
+**Integration Point:** [`src/main.c:1810`](src/main.c:1810)
+
+```c
+// Initialize subscription manager mutexes
+if (pthread_mutex_init(&g_subscription_manager.subscriptions_lock, NULL) != 0) {
+    DEBUG_ERROR("Failed to initialize subscriptions mutex");
+    sqlite3_close(g_db);
+    return 1;
+}
+
+if (pthread_mutex_init(&g_subscription_manager.ip_tracking_lock, NULL) != 0) {
+    DEBUG_ERROR("Failed to initialize IP tracking mutex");
+    pthread_mutex_destroy(&g_subscription_manager.subscriptions_lock);
+    sqlite3_close(g_db);
+    return 1;
+}
+
+// **NEW: Startup cleanup - close all subscriptions**
+cleanup_all_subscriptions_on_startup();
+
+// Start WebSocket relay server
+DEBUG_LOG("Starting WebSocket relay server...");
+if (start_websocket_relay(port_override, strict_port) != 0) {
+    DEBUG_ERROR("Failed to start WebSocket relay");
+    // ... cleanup code
+}
+```
+
+### Benefits
+- **Immediate relief**: Restart relay to fix subscription issues
+- **Clean slate**: Every restart starts with zero active subscriptions
+- **Simple**: Single SQL UPDATE statement
+- **Nostr-aligned**: Clients are designed to reconnect after relay restart
+- **No configuration needed**: Always runs on startup
+
+---
+
+## Component 2: Connection Age Limit
+
+### Purpose
+Automatically disconnect clients after a configurable time period, forcing them to reconnect and re-establish subscriptions.
+
+### Why Disconnect Instead of Just Closing Subscriptions?
+
+**Option 1: Send CLOSED message (keep connection)**
+- ❌ Not all clients handle `CLOSED` messages properly
+- ❌ Silent failure - client thinks it's subscribed but isn't
+- ❌ Partial cleanup - connection still consumes resources
+- ❌ More complex to implement
+
+**Option 2: Disconnect client entirely (force reconnection)** ✅
+- ✅ Universal compatibility - all clients handle WebSocket reconnection
+- ✅ Complete resource cleanup (memory, file descriptors, etc.)
+- ✅ Simple implementation - single operation
+- ✅ Well-tested code path (same as network interruptions)
+- ✅ Forces re-authentication if needed
+
+### Implementation
+
+**File:** [`src/websockets.c`](src/websockets.c)
+
+**New Function:**
+```c
+/**
+ * Check connection age and disconnect clients that have been connected too long.
+ * This forces clients to reconnect and re-establish subscriptions.
+ *
+ * Uses libwebsockets' lws_vhost_foreach_wsi() to iterate through all active
+ * connections and checks their connection_established timestamp from per_session_data.
+ */
+void check_connection_age(int max_connection_seconds) {
+    if (max_connection_seconds <= 0 || !ws_context) {
+        return;
+    }
+    
+    time_t now = time(NULL);
+    time_t cutoff = now - max_connection_seconds;
+    
+    // Get the default vhost
+    struct lws_vhost *vhost = lws_get_vhost_by_name(ws_context, "default");
+    if (!vhost) {
+        DEBUG_ERROR("Failed to get vhost for connection age check");
+        return;
+    }
+    
+    // Iterate through all active WebSocket connections
+    // Note: lws_vhost_foreach_wsi() calls our callback for each connection
+    struct lws *wsi = NULL;
+    while ((wsi = lws_vhost_foreach_wsi(vhost, wsi)) != NULL) {
+        // Get per-session data which contains connection_established timestamp
+        struct per_session_data *pss = (struct per_session_data *)lws_wsi_user(wsi);
+        
+        if (pss && pss->connection_established > 0) {
+            // Check if connection is older than cutoff
+            if (pss->connection_established < cutoff) {
+                // Connection is too old - close it
+                long age_seconds = now - pss->connection_established;
+                
+                DEBUG_LOG("Closing connection from %s (age: %lds, limit: %ds)",
+                         pss->client_ip, age_seconds, max_connection_seconds);
+                
+                // Close with normal status and reason message
+                lws_close_reason(wsi, LWS_CLOSE_STATUS_NORMAL,
+                               (unsigned char *)"connection age limit", 21);
+            }
+        }
+    }
+}
+```
+
+**Key Implementation Details:**
+
+1. **No database needed**: Active connections are tracked by libwebsockets itself
+2. **Uses existing timestamp**: `pss->connection_established` is already set on line 456 of websockets.c
+3. **Built-in iterator**: `lws_vhost_foreach_wsi()` safely iterates through all active connections
+4. **Per-session data**: Each connection's `per_session_data` is accessible via `lws_wsi_user()`
+5. **Safe closure**: `lws_close_reason()` properly closes the WebSocket with a status code and message
+
+**Integration Point:** [`src/websockets.c:2176`](src/websockets.c:2176) - in existing event loop
+
+```c
+// Main event loop with proper signal handling
+while (g_server_running && !g_shutdown_flag) {
+    int result = lws_service(ws_context, 1000);
+
+    if (result < 0) {
+        DEBUG_ERROR("libwebsockets service error");
+        break;
+    }
+
+    // Check if it's time to post status update
+    time_t current_time = time(NULL);
+    int status_post_hours = get_config_int("kind_1_status_posts_hours", 0);
+
+    if (status_post_hours > 0) {
+        int seconds_interval = status_post_hours * 3600;
+        if (current_time - last_status_post_time >= seconds_interval) {
+            last_status_post_time = current_time;
+            generate_and_post_status_event();
+        }
+    }
+    
+    // **NEW: Check for connection age limit**
+    int max_connection_seconds = get_config_int("max_connection_seconds", 86400); // Default 24 hours
+    if (max_connection_seconds > 0) {
+        check_connection_age(max_connection_seconds);
+    }
+}
+```
+
+### Configuration
+
+**Parameter:** `max_connection_seconds`
+- **Default:** `86400` (24 hours)
+- **Range:** `0` = disabled, `>0` = disconnect after X seconds
+- **Units:** Seconds (for consistency with other time-based configs)
+
+**Example configurations:**
+```json
+{
+  "max_connection_seconds": 86400   // 86400 seconds = 24 hours (default)
+}
+```
+
+```json
+{
+  "max_connection_seconds": 43200   // 43200 seconds = 12 hours
+}
+```
+
+```json
+{
+  "max_connection_seconds": 3600    // 3600 seconds = 1 hour
+}
+```
+
+```json
+{
+  "max_connection_seconds": 0       // Disabled
+}
+```
+
+### Client Behavior
+
+When disconnected due to age limit, clients will:
+1. Detect WebSocket closure
+2. Wait briefly (exponential backoff)
+3. Reconnect to relay
+4. Re-authenticate if needed (NIP-42)
+5. Re-establish all subscriptions
+6. Resume normal operation
+
+This is **exactly what happens** during network interruptions, so it's a well-tested code path in all Nostr clients.
+
+### Benefits
+- **No new threads**: Uses existing event loop
+- **Minimal overhead**: Check runs once per second (same as `lws_service`)
+- **Simple implementation**: Iterate through active connections
+- **Consistent pattern**: Matches existing status post checking
+- **Universal compatibility**: All clients handle reconnection
+- **Complete cleanup**: Frees all resources associated with connection
+- **Configurable**: Can be adjusted per relay needs or disabled entirely
+
+---
+
+## Implementation Plan
+
+### Phase 1: Startup Cleanup (1-2 hours)
+
+1. **Add `cleanup_all_subscriptions_on_startup()` function**
+   - File: [`src/subscriptions.c`](src/subscriptions.c)
+   - SQL UPDATE to mark all active subscriptions as disconnected
+   - Add logging for cleanup count
+
+2. **Integrate in main()**
+   - File: [`src/main.c:1810`](src/main.c:1810)
+   - Call after mutex initialization, before WebSocket server start
+
+3. **Test**
+   - Create subscriptions in database
+   - Restart relay
+   - Verify all subscriptions marked as disconnected
+   - Verify `active_subscriptions_log` shows 0 subscriptions
+
+**Estimated Time:** 1-2 hours
+
+### Phase 2: Connection Age Limit (2-3 hours)
+
+1. **Add `check_connection_age()` function**
+   - File: [`src/websockets.c`](src/websockets.c)
+   - Iterate through active connections
+   - Close connections older than limit
+
+2. **Integrate in event loop**
+   - File: [`src/websockets.c:2176`](src/websockets.c:2176)
+   - Add check after status post check
+   - Use same pattern as status posts
+
+3. **Add configuration parameter**
+   - Add `max_connection_seconds` to default config
+   - Default: 86400 (24 hours)
+
+4. **Test**
+   - Connect client
+   - Wait for timeout (or reduce timeout for testing)
+   - Verify client disconnected
+   - Verify client reconnects automatically
+   - Verify subscriptions re-established
+
+**Estimated Time:** 2-3 hours
+
+---
+
+## Testing Strategy
+
+### Startup Cleanup Tests
+
+```bash
+# Test 1: Clean startup with existing subscriptions
+- Create 100 active subscriptions in database
+- Restart relay
+- Verify all subscriptions marked as disconnected
+- Verify active_subscriptions_log shows 0 subscriptions
+
+# Test 2: Clean startup with no subscriptions
+- Start relay with empty database
+- Verify no errors
+- Verify startup cleanup logs "No active subscriptions found"
+
+# Test 3: Clients reconnect after restart
+- Create subscriptions before restart
+- Restart relay
+- Connect clients and create new subscriptions
+- Verify new subscriptions tracked correctly
+```
+
+### Connection Age Limit Tests
+
+```bash
+# Test 1: Connection disconnected after timeout
+- Set max_connection_seconds to 60 (for testing)
+- Connect client
+- Wait 61 seconds
+- Verify client disconnected
+- Verify client reconnects automatically
+
+# Test 2: Subscriptions re-established after reconnection
+- Connect client with subscriptions
+- Wait for timeout
+- Verify client reconnects
+- Verify subscriptions re-established
+- Verify events still delivered
+
+# Test 3: Disabled when set to 0
+- Set max_connection_seconds to 0
+- Connect client
+- Wait extended period
+- Verify client NOT disconnected
+```
+
+### Integration Tests
+
+```bash
+# Test 1: Combined behavior
+- Start relay (startup cleanup runs)
+- Connect multiple clients
+- Create subscriptions
+- Wait for connection timeout
+- Verify clients reconnect
+- Restart relay
+- Verify clean state
+
+# Test 2: Load test
+- Connect 100 clients
+- Each creates 5 subscriptions
+- Wait for connection timeout
+- Verify all clients reconnect
+- Verify all subscriptions re-established
+- Monitor CPU usage (should remain low)
+```
+
+---
+
+## Success Criteria
+
+### Component 1: Startup Cleanup
+- ✅ Relay starts with zero active subscriptions
+- ✅ All previous subscriptions marked as disconnected on startup
+- ✅ Clients successfully reconnect and re-establish subscriptions
+- ✅ Relay restart can be used as emergency fix for subscription issues
+- ✅ No errors during startup cleanup process
+
+### Component 2: Connection Age Limit
+- ✅ Clients disconnected after configured time period
+- ✅ Clients automatically reconnect
+- ✅ Subscriptions re-established after reconnection
+- ✅ No impact on relay performance
+- ✅ Configuration parameter works correctly (including disabled state)
+
+### Overall Success
+- ✅ CPU usage remains low (<10%)
+- ✅ No orphaned subscriptions accumulate
+- ✅ Database size remains stable
+- ✅ No manual intervention required
+
+---
+
+## Configuration Reference
+
+**New Configuration Parameters:**
+
+```json
+{
+  "max_connection_seconds": 86400
+}
+```
+
+**Recommended Settings:**
+
+- **Production:** 
+  - `max_connection_seconds: 86400` (24 hours)
+
+- **Development:**
+  - `max_connection_seconds: 3600` (1 hour for faster testing)
+
+- **High-traffic:**
+  - `max_connection_seconds: 43200` (12 hours)
+
+- **Disabled:**
+  - `max_connection_seconds: 0`
+
+---
+
+## Rollback Plan
+
+If issues arise after deployment:
+
+1. **Disable connection age limit:**
+   - Set `max_connection_seconds: 0` in config
+   - Restart relay
+   - Monitor for stability
+
+2. **Revert code changes:**
+   - Remove `check_connection_age()` call from event loop
+   - Remove `cleanup_all_subscriptions_on_startup()` call from main
+   - Restart relay
+
+3. **Database cleanup (if needed):**
+   - Manually clean up orphaned subscriptions using SQL:
+     ```sql
+     UPDATE subscriptions 
+     SET ended_at = strftime('%s', 'now') 
+     WHERE event_type = 'created' AND ended_at IS NULL;
+     ```
+
+---
+
+## Comparison with Original Design
+
+### Original Design (5 Components)
+1. Startup cleanup
+2. Fix WebSocket disconnection logging
+3. Enhance subscription removal with reason parameter
+4. Periodic cleanup task (background thread)
+5. Optimize database VIEW
+6. Subscription expiration (optional)
+
+### Simplified Design (2 Components)
+1. Startup cleanup
+2. Connection age limit
+
+### Why Simplified is Better
+
+**Advantages:**
+- **Simpler**: 2 components vs 5-6 components
+- **Faster to implement**: 3-5 hours vs 11-17 hours
+- **Easier to maintain**: Less code, fewer moving parts
+- **More reliable**: Fewer potential failure points
+- **Nostr-aligned**: Leverages client reconnection behavior
+- **No new threads**: Uses existing event loop
+- **Universal compatibility**: All clients handle reconnection
+
+**What We're Not Losing:**
+- Startup cleanup is identical in both designs
+- Connection age limit achieves the same goal as periodic cleanup + expiration
+- Disconnection forces complete cleanup (better than just logging)
+- Database VIEW optimization not needed if subscriptions don't accumulate
+
+**Trade-offs:**
+- Less granular logging (but simpler)
+- No historical subscription analytics (but cleaner database)
+- Clients must reconnect periodically (but this is standard Nostr behavior)
+
+---
+
+## Conclusion
+
+This simplified design solves the subscription accumulation problem with two pragmatic solutions:
+
+1. **Startup cleanup** ensures every relay restart starts with a clean slate
+2. **Connection age limit** prevents long-term accumulation by forcing periodic reconnection
+
+Both solutions align with Nostr's stateless design where clients are expected to handle reconnection. The implementation is simple, maintainable, and leverages existing code patterns.
+
+**Key Benefits:**
+- ✅ Solves the root problem (subscription accumulation)
+- ✅ Simple to implement (3-5 hours total)
+- ✅ Easy to maintain (minimal code)
+- ✅ Universal compatibility (all clients handle reconnection)
+- ✅ No new threads or background tasks
+- ✅ Configurable and can be disabled if needed
+- ✅ Relay restart as emergency fix
+
+**Next Steps:**
+1. Implement Component 1 (Startup Cleanup)
+2. Test thoroughly
+3. Implement Component 2 (Connection Age Limit)
+4. Test thoroughly
+5. Deploy to production
+6. Monitor CPU usage and subscription counts

+# Subscription Table Collapsible Groups Implementation Plan
+
+## Objective
+Add collapsible/expandable functionality to subscription groups, where:
+1. Each WSI Pointer group starts collapsed, showing only a summary row
+2. Clicking the summary row expands to show all subscription details for that WSI Pointer
+3. Clicking again collapses the group back to the summary row
+
+## Current Behavior
+- All subscriptions are displayed in a flat list
+- WSI Pointer value shown only on first row of each group
+- No interaction or collapse functionality
+
+## Desired Behavior
+- **Collapsed state**: One row per WSI Pointer showing summary information
+- **Expanded state**: Header row + detail rows for each subscription in that group
+- **Toggle**: Click on header row to expand/collapse
+- **Visual indicator**: Arrow or icon showing expand/collapse state
+
+## Design Approach
+
+### Option 1: Summary Row + Detail Rows (Recommended)
+```
+[▶] WSI Pointer: 0x12345678 | Subscriptions: 3 | Total Duration: 15m
+    (detail rows hidden)
+
+When clicked:
+[▼] WSI Pointer: 0x12345678 | Subscriptions: 3 | Total Duration: 15m
+    | sub-001 | 5m 30s | kinds:[1]
+    | sub-002 | 3m 15s | kinds:[3]
+    | sub-003 | 6m 15s | kinds:[1,3]
+```
+
+### Option 2: First Row as Header (Alternative)
+```
+[▶] 0x12345678 | sub-001 | 5m 30s | kinds:[1] (+ 2 more)
+
+When clicked:
+[▼] 0x12345678 | sub-001 | 5m 30s | kinds:[1]
+               | sub-002 | 3m 15s | kinds:[3]
+               | sub-003 | 6m 15s | kinds:[1,3]
+```
+
+**Recommendation**: Option 1 provides clearer UX and better summary information.
+
+## Implementation Details
+
+### Files to Modify
+1. `api/index.js` - Function `populateSubscriptionDetailsTable()` (lines 4277-4384)
+2. `api/index.css` - Add styles for collapsible rows
+
+### Data Structure Changes
+
+Need to group subscriptions by WSI Pointer first:
+```javascript
+// Group subscriptions by wsi_pointer
+const groupedSubscriptions = {};
+subscriptionsData.forEach(sub => {
+    const wsiKey = sub.wsi_pointer || 'N/A';
+    if (!groupedSubscriptions[wsiKey]) {
+        groupedSubscriptions[wsiKey] = [];
+    }
+    groupedSubscriptions[wsiKey].push(sub);
+});
+```
+
+### HTML Structure
+
+#### Summary Row (Header)
+```html
+<tr class="subscription-group-header" data-wsi-pointer="0x12345678" data-expanded="false">
+    <td colspan="4" style="cursor: pointer; user-select: none;">
+        <span class="expand-icon">▶</span>
+        <strong>WSI Pointer:</strong> 0x12345678
+        <span class="group-summary">
+            | Subscriptions: 3 | Oldest: 15m 30s
+        </span>
+    </td>
+</tr>
+```
+
+#### Detail Rows (Initially Hidden)
+```html
+<tr class="subscription-detail-row" data-wsi-group="0x12345678" style="display: none;">
+    <td style="padding-left: 30px;"><!-- Empty for WSI Pointer --></td>
+    <td>sub-001</td>
+    <td>5m 30s</td>
+    <td>kinds:[1]</td>
+</tr>
+```
+
+### JavaScript Implementation
+
+#### Modified populateSubscriptionDetailsTable Function
+
+```javascript
+function populateSubscriptionDetailsTable(subscriptionsData) {
+    const tableBody = document.getElementById('subscription-details-table-body');
+    if (!tableBody || !subscriptionsData || !Array.isArray(subscriptionsData)) return;

+
+## Features Included
+
+1. ✅ **Collapsible groups**: Each WSI Pointer group can be collapsed/expanded
+2. ✅ **Visual indicator**: Arrow icon (▶/▼) shows current state
+3. ✅ **Summary information**: Shows subscription count and oldest duration
+4. ✅ **Smooth transitions**: Icon rotation animation

+# Subscription Table WSI Pointer Grouping Implementation Plan
+
+## Objective
+Modify the subscription details table to show the WSI Pointer value only once per group - on the first row of each WSI Pointer group, leaving it blank for subsequent rows with the same WSI Pointer.
+
+## Current Behavior
+- All rows show the WSI Pointer value
+- Rows are sorted by WSI Pointer (grouping is working)
+- Visual grouping is not clear
+
+## Desired Behavior
+- First row of each WSI Pointer group shows the full WSI Pointer value
+- Subsequent rows in the same group have an empty cell for WSI Pointer
+- This creates a clear visual grouping effect
+
+## Implementation Details
+
+### File to Modify
+`api/index.js` - Function `populateSubscriptionDetailsTable()` (lines 4277-4384)
+
+### Code Changes Required
+
+#### Current Code (lines 4291-4383):
+```javascript
+// Sort subscriptions by wsi_pointer to group them together
+subscriptionsData.sort((a, b) => {
+    const wsiA = a.wsi_pointer || '';
+    const wsiB = b.wsi_pointer || '';
+    return wsiA.localeCompare(wsiB);
+});
+
+subscriptionsData.forEach((subscription, index) => {
+    const row = document.createElement('tr');
+
+    // Calculate duration
+    const now = Math.floor(Date.now() / 1000);
+    const duration = now - subscription.created_at;
+    const durationStr = formatDuration(duration);
+
+    // Format client IP (show full IP for admin view)
+    const clientIP = subscription.client_ip || 'unknown';
+
+    // Format wsi_pointer (show full pointer)
+    const wsiPointer = subscription.wsi_pointer || 'N/A';
+
+    // Format filters (show actual filter details)
+    let filtersDisplay = 'None';
+    // ... filter formatting code ...
+
+    row.innerHTML = `
+        <td style="font-family: 'Courier New', monospace; font-size: 12px;">${wsiPointer}</td>
+        <td style="font-family: 'Courier New', monospace; font-size: 12px;">${subscription.id || 'N/A'}</td>
+        <!-- <td style="font-family: 'Courier New', monospace; font-size: 12px;">${clientIP}</td> -->
+        <td>${durationStr}</td>
+        <td>${filtersDisplay}</td>
+    `;
+    tableBody.appendChild(row);
+});
+```
+
+#### Modified Code:
+```javascript
+// Sort subscriptions by wsi_pointer to group them together
+subscriptionsData.sort((a, b) => {
+    const wsiA = a.wsi_pointer || '';
+    const wsiB = b.wsi_pointer || '';
+    return wsiA.localeCompare(wsiB);
+});
+
+// Track previous WSI Pointer to detect group changes
+let previousWsiPointer = null;
+
+subscriptionsData.forEach((subscription, index) => {
+    const row = document.createElement('tr');
+
+    // Calculate duration
+    const now = Math.floor(Date.now() / 1000);
+    const duration = now - subscription.created_at;
+    const durationStr = formatDuration(duration);
+
+    // Format client IP (show full IP for admin view)
+    const clientIP = subscription.client_ip || 'unknown';
+
+    // Format wsi_pointer - only show if it's different from previous row
+    const currentWsiPointer = subscription.wsi_pointer || 'N/A';
+    let wsiPointerDisplay = '';
+    
+    if (currentWsiPointer !== previousWsiPointer) {
+        // This is the first row of a new group - show the WSI Pointer
+        wsiPointerDisplay = currentWsiPointer;
+        previousWsiPointer = currentWsiPointer;
+    } else {
+        // This is a continuation of the same group - leave blank
+        wsiPointerDisplay = '';
+    }
+
+    // Format filters (show actual filter details)
+    let filtersDisplay = 'None';
+    // ... filter formatting code remains the same ...
+
+    row.innerHTML = `
+        <td style="font-family: 'Courier New', monospace; font-size: 12px;">${wsiPointerDisplay}</td>
+        <td style="font-family: 'Courier New', monospace; font-size: 12px;">${subscription.id || 'N/A'}</td>
+        <!-- <td style="font-family: 'Courier New', monospace; font-size: 12px;">${clientIP}</td> -->
+        <td>${durationStr}</td>
+        <td>${filtersDisplay}</td>
+    `;
+    tableBody.appendChild(row);
+});
+```
+
+### Key Changes Explained
+
+1. **Add tracking variable**: `let previousWsiPointer = null;` before the forEach loop
+2. **Store current WSI Pointer**: `const currentWsiPointer = subscription.wsi_pointer || 'N/A';`
+3. **Compare with previous**: Check if `currentWsiPointer !== previousWsiPointer`
+4. **Conditional display**:
+   - If different: Show the WSI Pointer value and update `previousWsiPointer`
+   - If same: Show empty string (blank cell)
+5. **Use display variable**: Replace `${wsiPointer}` with `${wsiPointerDisplay}` in the row HTML
+
+### Visual Result
+
+**Before:**
+```
+WSI Pointer    | Subscription ID | Duration | Filters
+0x12345678     | sub-001        | 5m 30s   | kinds:[1]
+0x12345678     | sub-002        | 3m 15s   | kinds:[3]
+0x87654321     | sub-003        | 1m 45s   | kinds:[1,3]
+```
+
+**After:**
+```
+WSI Pointer    | Subscription ID | Duration | Filters
+0x12345678     | sub-001        | 5m 30s   | kinds:[1]
+               | sub-002        | 3m 15s   | kinds:[3]
+0x87654321     | sub-003        | 1m 45s   | kinds:[1,3]
+```
+
+## Testing Checklist
+
+1. ✅ Verify first row of each group shows WSI Pointer
+2. ✅ Verify subsequent rows in same group are blank
+3. ✅ Verify grouping works with multiple subscriptions per WSI Pointer
+4. ✅ Verify single subscription per WSI Pointer still shows the value
+5. ✅ Verify empty/null WSI Pointers are handled correctly
+6. ✅ Verify table still displays correctly when no subscriptions exist
+
+## Next Steps
+
+1. Review this plan
+2. Switch to Code mode
+3. Implement the changes in `api/index.js`
+4. Test the implementation
+5. Verify the visual grouping effect

+# c-relay-pg Plan — PostgreSQL Backend + Multi-Instance + Dashboard
+
+## Overview
+
+**c-relay-pg** is a new project (separate repository) forked from c-relay after the `db_ops` abstraction layer is complete. It replaces the SQLite backend with PostgreSQL, enabling horizontal scaling, external dashboards, and production-grade deployments.
+
+### Prerequisites
+
+- The `db_ops.h` / `db_ops.c` abstraction layer must be complete in c-relay first — see [c-relay thread pool plan](c_relay_thread_pool_plan.md) Phase 1.
+- The fork happens after Phase 1 of that plan is done and tested.
+
+### Why a Separate Project?
+
+| | c-relay | c-relay-pg |
+|---|---------|-----------|
+| **Database** | SQLite (embedded) | PostgreSQL (client-server) |
+| **Deployment** | Single binary + DB file | Binary + PostgreSQL server |
+| **Scaling** | Single instance | Multiple instances + load balancer |
+| **Dashboard** | Embedded web UI | Separate web server + Grafana |
+| **Target user** | Personal relay, small community | Medium-large relay, production |
+| **Complexity** | Minimal | More infrastructure |
+
+For the full analysis of why PostgreSQL was chosen over MySQL/MariaDB and other databases, see the [database architecture analysis](database_architecture_analysis.md).
+

+```
+
+---
+
+## Phase 1: PostgreSQL Backend
+
+### Goal
+
+Fork c-relay into a new repository called **c-relay-pg**. Replace the SQLite `db_ops` implementation with PostgreSQL using `libpq`. The `db_ops.h` interface stays identical — only the backend changes.
+
+### New Files
+
+- `src/db_ops_sqlite.c` — Renamed from `db_ops.c` (the Phase 1 SQLite implementation from c-relay)
+- `src/db_ops_postgres.c` — New PostgreSQL implementation
+- `src/db_ops.c` — Thin dispatcher that calls the active backend
+
+### PostgreSQL Schema

+
+### Key Implementation Details
+
+#### Tag Queries with JSONB
+
+The biggest win — replacing the `event_tags` subquery with JSONB containment:
+
+```c
+// SQLite (current): subquery into event_tags table
+// AND id IN (SELECT event_id FROM event_tags WHERE tag_name = ? AND tag_value IN (?))
+
+// PostgreSQL: JSONB containment operator with GIN index
+// AND tags @> '[["p", "pubkey_hex"]]'
+
+// For multiple tag values:
+// AND (tags @> '[["p", "val1"]]' OR tags @> '[["p", "val2"]]')
+```
+
+This eliminates the entire `event_tags` table (4 million rows, ~2 GB indexes in the current SQLite schema). The GIN index on JSONB handles everything in ~100–200 MB.
+
+#### LISTEN/NOTIFY Integration
+
+For cross-instance event broadcasting:
+
+```c
+// In db_ops_postgres.c:
+int db_notify_new_event(const char* event_id) {
+    char cmd[128];
+    snprintf(cmd, sizeof(cmd), "NOTIFY new_event, '%s'", event_id);
+    PGresult* res = PQexec(g_pg_conn, cmd);
+    PQclear(res);
+    return 0;
+}
+
+// Called from the lws event loop every iteration:
+int db_check_notifications(char* event_id_out, size_t max_len) {
+    PQconsumeInput(g_pg_notify_conn);
+    PGnotify* notify = PQnotifies(g_pg_notify_conn);
+    if (notify) {
+        strncpy(event_id_out, notify->extra, max_len);
+        PQfreemem(notify);
+        return 1;  // Got a notification
+    }
+    return 0;  // No notifications
+}
+```
+
+#### Connection Management
+
+```c
+// db_ops_postgres.c connection pool (simple version)
+#define DB_POOL_SIZE 4
+
+static PGconn* g_pg_read_pool[DB_POOL_SIZE];  // For REQ queries
+static PGconn* g_pg_write_conn;                // For EVENT inserts
+static PGconn* g_pg_notify_conn;               // For LISTEN/NOTIFY
+static pthread_mutex_t g_pool_lock;
+
+PGconn* db_get_read_connection(void) {
+    pthread_mutex_lock(&g_pool_lock);
+    // Round-robin or find idle connection
+    // ...
+    pthread_mutex_unlock(&g_pool_lock);
+}
+```
+
+### Build System Changes
+
+```makefile
+# Makefile additions
+DB_BACKEND ?= sqlite  # Default to sqlite, override with: make DB_BACKEND=postgres
+
+ifeq ($(DB_BACKEND),postgres)
+    MAIN_SRC += src/db_ops.c src/db_ops_postgres.c
+    LIBS += -lpq
+    CFLAGS += -DDB_BACKEND_POSTGRES
+else
+    MAIN_SRC += src/db_ops.c src/db_ops_sqlite.c
+    CFLAGS += -DDB_BACKEND_SQLITE
+endif
+```
+
+### Data Migration Tool
+
+A standalone tool to migrate existing SQLite data to PostgreSQL:
+
+```bash
+# migrate_to_postgres.sh
+# 1. Export events from SQLite
+sqlite3 old_relay.db ".mode csv" "SELECT id,pubkey,created_at,kind,event_type,content,sig,tags,event_json,first_seen FROM events" > events.csv
+
+# 2. Import into PostgreSQL
+psql -d crelay -c "\COPY events FROM 'events.csv' WITH CSV"
+
+# 3. Migrate config
+sqlite3 old_relay.db ".mode csv" "SELECT key,value,data_type,description,category,requires_restart FROM config" > config.csv
+psql -d crelay -c "\COPY config(key,value,data_type,description,category,requires_restart) FROM 'config.csv' WITH CSV"
+
+# 4. Migrate auth rules
+sqlite3 old_relay.db ".mode csv" "SELECT rule_type,pattern_type,pattern_value,active FROM auth_rules" > auth_rules.csv
+psql -d crelay -c "\COPY auth_rules(rule_type,pattern_type,pattern_value,active) FROM 'auth_rules.csv' WITH CSV"
+
+# 5. Refresh materialized views
+psql -d crelay -c "REFRESH MATERIALIZED VIEW event_kinds_mv; REFRESH MATERIALIZED VIEW time_stats_mv; REFRESH MATERIALIZED VIEW top_pubkeys_mv;"
+```

+
+## Phase 2: Multi-Instance + Dashboard
+
+### Goal
+
+Run multiple c-relay-pg instances behind a load balancer with a separate dashboard web server, all sharing the same PostgreSQL database.
+
+### Components
+
+1. **nginx config** — WebSocket load balancing with `ip_hash` stickiness
+2. **systemd template** — `c-relay-pg@.service` for multiple instances
+3. **LISTEN/NOTIFY integration** — Cross-instance event broadcasting in the `lws_service()` loop
+4. **PgBouncer** — Connection pooling between c-relay-pg instances and PostgreSQL
+5. **Dashboard** — Separate web server querying PostgreSQL directly
+6. **Materialized view refresh** — Background job to refresh analytics views
+
+### Multi-Instance Architecture

+
+### nginx Load Balancing Config
+
+```nginx
+# nginx.conf - WebSocket load balancing for c-relay-pg
+upstream relay_backends {
+    # ip_hash ensures a client always hits the same instance
+    # (important for WebSocket session stickiness)
+    ip_hash;
+    
+    server 127.0.0.1:8888;
+    server 127.0.0.1:8889;
+    server 127.0.0.1:8890;
+}
+
+server {
+    listen 443 ssl;
+    server_name relay.example.com;
+    
+    # TLS config...
+    
+    location / {
+        proxy_pass http://relay_backends;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_read_timeout 86400;  # Keep WebSocket alive for 24h
+    }
+    
+    # Dashboard on separate path
+    location /dashboard {
+        proxy_pass http://127.0.0.1:3000;
+    }
+}
+```
+
+**Session stickiness** (`ip_hash`) ensures that once a client connects to Instance 2, all their subsequent WebSocket frames go to Instance 2. This is important because subscriptions are held in-memory per instance.
+
+### Starting Multiple Instances
+
+Each instance is the same binary, just on a different port, all pointing to the same PostgreSQL:
+
+```bash
+# Instance 1
+./build/c_relay_x86 --port 8888 --db-host localhost --db-name crelay &
+
+# Instance 2
+./build/c_relay_x86 --port 8889 --db-host localhost --db-name crelay &
+
+# Instance 3
+./build/c_relay_x86 --port 8890 --db-host localhost --db-name crelay &
+```
+
+Or with systemd template units:
+
+```ini
+# /etc/systemd/system/c-relay-pg@.service
+[Unit]
+Description=C-Relay-PG Nostr Instance %i
+After=postgresql.service
+
+[Service]
+ExecStart=/opt/c-relay-pg/c_relay_x86 --port %i --db-host localhost --db-name crelay
+Restart=always
+User=c-relay
+
+[Install]
+WantedBy=multi-user.target
+```
+
+```bash
+systemctl enable c-relay-pg@8888 c-relay-pg@8889 c-relay-pg@8890
+systemctl start c-relay-pg@8888 c-relay-pg@8889 c-relay-pg@8890
+```
+
+### Cross-Instance Event Broadcasting
+
+When Instance 1 receives a new EVENT and stores it in PostgreSQL, Instance 2 and Instance 3 need to know about it so they can broadcast to their connected subscribers.
+
+```mermaid
+sequenceDiagram
+    participant Client_A as Client A - connected to Instance 1
+    participant I1 as Instance 1
+    participant PG as PostgreSQL
+    participant I2 as Instance 2
+    participant I3 as Instance 3
+    participant Client_B as Client B - connected to Instance 2
+    participant Client_C as Client C - connected to Instance 3
+
+    Client_A->>I1: EVENT - new kind:1 note
+    I1->>PG: INSERT INTO events...
+    PG-->>I1: OK
+    I1->>I1: broadcast to local subscribers
+    I1->>PG: NOTIFY new_event with event_id
+    
+    Note over PG: PostgreSQL delivers notification to all listeners
+    
+    PG-->>I2: NOTIFY: new_event event_id
+    PG-->>I3: NOTIFY: new_event event_id
+    
+    I2->>PG: SELECT event_json FROM events WHERE id = event_id
+    PG-->>I2: event JSON
+    I2->>I2: match against local subscriptions
+    I2->>Client_B: EVENT message - if subscription matches
+    
+    I3->>PG: SELECT event_json FROM events WHERE id = event_id
+    PG-->>I3: event JSON
+    I3->>I3: match against local subscriptions
+    I3->>Client_C: EVENT message - if subscription matches
+```
+
+#### PostgreSQL LISTEN/NOTIFY Implementation
+
+Built into PostgreSQL — no additional infrastructure needed:
+
+```c
+// === In the relay's event loop (modified lws_service loop) ===
+
+// Setup: create a dedicated connection for LISTEN
+PGconn* notify_conn = PQconnectdb("host=localhost dbname=crelay");
+PQexec(notify_conn, "LISTEN new_event");
+int notify_fd = PQsocket(notify_conn);  // Get the socket fd for poll()
+
+// After storing an event:
+void on_event_stored(PGconn* write_conn, const char* event_id) {
+    char notify_cmd[128];
+    snprintf(notify_cmd, sizeof(notify_cmd),
+             "NOTIFY new_event, '%s'", event_id);
+    PQexec(write_conn, notify_cmd);
+}
+
+// In the main event loop (runs every lws_service iteration):
+void check_cross_instance_events(PGconn* notify_conn) {
+    // Non-blocking check for notifications
+    PQconsumeInput(notify_conn);
+    
+    PGnotify* notify;
+    while ((notify = PQnotifies(notify_conn)) != NULL) {
+        // Another instance stored a new event
+        const char* event_id = notify->extra;
+        
+        // Fetch the event and check against local subscriptions
+        cJSON* event = db_get_event_by_id(event_id);
+        if (event) {
+            broadcast_event_to_subscriptions(event);
+            cJSON_Delete(event);
+        }
+        
+        PQfreemem(notify);
+    }
+}
+```
+
+**Performance**: LISTEN/NOTIFY adds ~1–5ms latency for cross-instance delivery. For a Nostr relay, this is imperceptible — clients already expect network latency.
+
+**Payload limit**: NOTIFY payloads are limited to 8000 bytes. For event IDs (64 hex chars), this is fine.
+
+#### Alternative: Redis Pub/Sub
+
+If you later need even lower latency or more sophisticated routing:
+
+```c
+// Using hiredis (Redis C client)
+redisContext* redis = redisConnect("127.0.0.1", 6379);
+
+// After storing event:
+redisCommand(redis, "PUBLISH new_event %s", event_json);
+
+// Subscriber (in each instance):
+redisCommand(redis, "SUBSCRIBE new_event");
+// Then poll for messages in the event loop
+```
+
+Redis adds sub-millisecond pub/sub but requires running a Redis server. For most relays, PostgreSQL LISTEN/NOTIFY is sufficient.
+
+### Connection Pooling with PgBouncer
+
+Each relay instance needs multiple database connections. Without pooling, 3 instances × 10 connections = 30 PostgreSQL backend processes. With PgBouncer:
+
+```ini
+# /etc/pgbouncer/pgbouncer.ini
+[databases]
+crelay = host=127.0.0.1 port=5432 dbname=crelay
+
+[pgbouncer]
+listen_port = 6432
+listen_addr = 127.0.0.1
+auth_type = md5
+pool_mode = transaction    # Return connection to pool after each transaction
+max_client_conn = 200      # Total connections from all relay instances
+default_pool_size = 20     # Actual PostgreSQL connections
+```
+
+Relay instances connect to PgBouncer (port 6432) instead of PostgreSQL directly (port 5432). PgBouncer multiplexes 200 client connections onto 20 actual PostgreSQL connections.
+
+### Zero-Downtime Deployment
+
+```mermaid
+sequenceDiagram
+    participant LB as nginx
+    participant I1 as Instance 1 - v1.0
+    participant I2 as Instance 2 - v1.0
+    participant I3 as Instance 3 - v1.0
+    participant I1_NEW as Instance 1 - v1.1
+
+    Note over LB,I3: Normal operation: 3 instances serving traffic
+    
+    LB->>I1: Mark upstream as down
+    Note over I1: Drain: wait for existing connections to close or timeout
+    I1->>I1: Graceful shutdown
+    
+    Note over LB: Traffic now goes to I2 and I3 only
+    
+    I1_NEW->>I1_NEW: Start with new binary
+    I1_NEW->>LB: Health check passes
+    LB->>I1_NEW: Mark upstream as up
+    
+    Note over LB,I1_NEW: Instance 1 now running v1.1, repeat for I2 and I3
+```
+
+Rolling deploy script:
+
+```bash
+#!/bin/bash
+# rolling_deploy.sh - Zero-downtime deployment
+
+for port in 8888 8889 8890; do
+    echo "Deploying instance on port $port..."
+    
+    # 1. Tell nginx to stop sending new connections
+    sed -i "s/server 127.0.0.1:$port;/server 127.0.0.1:$port down;/" /etc/nginx/nginx.conf
+    nginx -s reload
+    
+    # 2. Wait for existing connections to drain (30 seconds)
+    sleep 30
+    
+    # 3. Stop old instance
+    systemctl stop c-relay-pg@$port
+    
+    # 4. Deploy new binary
+    cp ./build/c_relay_x86 /opt/c-relay-pg/c_relay_x86
+    
+    # 5. Start new instance
+    systemctl start c-relay-pg@$port
+    
+    # 6. Wait for health check
+    sleep 5
+    
+    # 7. Re-enable in nginx
+    sed -i "s/server 127.0.0.1:$port down;/server 127.0.0.1:$port;/" /etc/nginx/nginx.conf
+    nginx -s reload
+    
+    echo "Instance on port $port deployed successfully"
+done
+```
+
+### Dashboard Options
+
+With PostgreSQL, the dashboard can be built with any technology:
+
+- **Grafana** — Point directly at PostgreSQL, zero custom code
+- **Custom web app** — React/Vue frontend + any backend (Node, Python, Go) querying PostgreSQL
+- **Embedded in c-relay-pg** — Keep current approach but queries go through `db_ops` to PostgreSQL (no longer blocks event loop since PostgreSQL handles concurrency)
+
+### Scaling Scenarios
+
+| Scenario | Instances | Connections | Events/hour | Setup |
+|----------|-----------|-------------|-------------|-------|
+| **Current** | 1 | ~1,200 | 56 | Single process + SQLite |
+| **Small upgrade** | 2 | ~2,500 | 500 | 2 instances + PostgreSQL |
+| **Medium relay** | 4 | ~5,000 | 5,000 | 4 instances + PostgreSQL + PgBouncer |
+| **Large relay** | 8 | ~10,000 | 50,000 | 8 instances + PostgreSQL + read replica |
+| **Multi-region** | 2–4 per region | ~50,000 | 500,000 | Multiple servers + PostgreSQL replication |
+
+### Cost Perspective
+
+Running multiple relay instances with PostgreSQL on a single VPS:
+- **PostgreSQL**: ~200–500 MB RAM baseline
+- **PgBouncer**: ~10 MB RAM
+- **Each relay instance**: ~50–100 MB RAM
+- **Dashboard web server**: ~50–100 MB RAM
+- **4 instances + PostgreSQL + PgBouncer + dashboard**: ~1–2 GB total RAM
+- A **$20/month VPS** with 4 cores and 4 GB RAM handles this easily
+- A **$40/month VPS** with 8 cores and 8 GB RAM handles 8 instances comfortably

+
+## Risk Mitigation
+
+| Risk | Mitigation |
+|------|-----------|
+| PostgreSQL connection failures | `db_ops` returns error codes. Relay logs errors but doesn't crash. Reconnection logic with exponential backoff. |
+| Performance regression | Benchmark before/after. PostgreSQL should be faster for complex queries, similar for simple ones. |
+| Data loss during migration | Migration tool is read-only on SQLite. PostgreSQL import is idempotent (INSERT ON CONFLICT). |
+| SQLite fallback needed | Keep `db_ops_sqlite.c` working. Compile-time flag switches backends. Can always go back. |
+| LISTEN/NOTIFY message loss | NOTIFY is transactional — if the INSERT commits, the NOTIFY is guaranteed. Missed notifications during reconnect handled by periodic full-sync. |
+| PgBouncer adds latency | Transaction pooling mode adds <0.1ms. Negligible compared to query time. |
+

+
+## Relationship to c-relay
+
+This project depends on the `db_ops.h` abstraction layer built in [c-relay thread pool plan](c_relay_thread_pool_plan.md) Phase 1. The interface is identical — only the backend implementation changes:
+
+- **c-relay**: `db_ops.c` → SQLite calls via `sqlite3_*`
+- **c-relay-pg**: `db_ops_postgres.c` → PostgreSQL calls via `libpq` (`PQexec`, `PQgetvalue`, etc.)
+
+The `db_ops.h` header file is shared between both projects. Changes to the interface should be coordinated.

+# c-relay Thread Pool Plan — db_ops Abstraction + SQLite Thread Pool
+
+## Overview
+
+This plan covers improvements to **c-relay** (this repo) — the lean, single-binary, embedded-SQLite Nostr relay. Two phases:
+
+1. **Phase 1: Database Abstraction Layer** — Consolidate all scattered `sqlite3_*` calls into a single `db_ops.h` / `db_ops.c` module. Pure refactor, no behavior change.
+2. **Phase 2: SQLite Thread Pool** — Add worker threads for concurrent reads, unblocking the `lws_service()` event loop.
+
+This is the **final form of c-relay**: an embedded-SQLite relay with clean architecture and non-blocking database access. The abstraction layer also enables a future fork to PostgreSQL — see [c-relay-pg plan](c_relay_pg_plan.md).
+
+### Why This First?
+
+The current architecture has a fundamental bottleneck documented in the [database architecture analysis](database_architecture_analysis.md): the single-threaded event loop blocks on every database call. A 672ms REQ query freezes every connected client. The thread pool fixes this without changing the database engine or deployment model.
+
+| Metric | Current | After Thread Pool |
+|--------|---------|-------------------|
+| **Event loop blocking** | 0.1–672ms per query | Near-zero |
+| **Concurrent reads** | 1 | 4–8 |
+| **Deployment** | Single binary + DB file | Same |
+| **Database** | SQLite | Same |
+| **Code risk** | N/A | Low — additive change |

+## Phase 1: Database Abstraction Layer
+
+### Goal
+
+Consolidate all 258 scattered `sqlite3_*` calls across 8 files into a single `db_ops.h` / `db_ops.c` module with a backend-agnostic interface. SQLite continues to work — this is a pure refactor.
+
+### Files That Currently Touch SQLite Directly
+
+| File | `sqlite3_*` calls | Operations |
+|------|-------------------|------------|
+| [`src/main.c`](../src/main.c) | ~80 | Event store/retrieve, tag storage, REQ queries, COUNT queries, DB init, schema migration |
+| [`src/config.c`](../src/config.c) | ~60 | Config CRUD, auth rules CRUD, WoT sync, relay key storage, startup sequence |
+| [`src/api.c`](../src/api.c) | ~40 | Stats queries, monitoring views, admin SQL execution, config management |
+| [`src/dm_admin.c`](../src/dm_admin.c) | ~20 | Auth rule management, WoT whitelist operations |
+| [`src/websockets.c`](../src/websockets.c) | ~15 | COUNT queries, IP ban stats, connection tracking |
+| [`src/subscriptions.c`](../src/subscriptions.c) | ~15 | Subscription logging — create/close/disconnect |
+| [`src/nip009.c`](../src/nip009.c) | ~10 | Event deletion — by ID and by address |
+| [`src/request_validator.c`](../src/request_validator.c) | ~8 | Blacklist/whitelist checks |

+
+### Migration Strategy for Phase 1
+
+The key principle: **change the interface, not the behavior**. Each function in `db_ops.c` initially just wraps the existing SQLite calls.
+
+**Step-by-step for each file:**
+
+1. **Create `db_ops.h` and `db_ops.c`** with the interface above
+2. **Implement each `db_ops` function** by moving the existing SQLite code from the source files into `db_ops.c`
+3. **Replace direct `sqlite3_*` calls** in each source file with `db_ops_*` calls
+4. **Remove `extern sqlite3* g_db`** from each file — only `db_ops.c` knows about `g_db`
+5. **Remove `#include <sqlite3.h>`** from each file — only `db_ops.c` includes it
+6. **Update Makefile** to compile `db_ops.c`
+
+### Order of Migration (by risk, lowest first)
+
+1. **`src/ip_ban.c`** — Self-contained, simple CRUD. Good warmup.
+2. **`src/subscriptions.c`** — Logging only, no critical path.
+3. **`src/nip009.c`** — Event deletion, small file.
+4. **`src/request_validator.c`** — Auth checks, small file.
+5. **`src/api.c`** — Stats/monitoring queries. Larger but read-only.
+6. **`src/dm_admin.c`** — Auth rules + WoT. Medium complexity.
+7. **`src/config.c`** — Config CRUD. Large but well-structured.
+8. **`src/websockets.c`** — COUNT queries, minimal DB usage.
+9. **`src/main.c`** — Event store/retrieve, REQ queries. The big one — do last.
+
+### Testing Phase 1
+
+After Phase 1, the relay should behave **identically** to before. Run:
+- `tests/run_all_tests.sh` — Full test suite
+- `tests/performance_benchmarks.sh` — Verify no performance regression
+- Manual testing with production-like traffic
+
+---
+
+## Phase 2: SQLite Thread Pool
+
+### Goal
+
+Add a pool of N worker threads, each with its own `sqlite3*` connection to the same database file. SQLite WAL mode (already enabled) supports **concurrent readers**. The event loop dispatches database work to the pool and remains responsive.
+
+### Key Design Points
+
+1. **Read path**: REQ queries dispatched to thread pool. Each worker opens its own `sqlite3*` connection. SQLite WAL allows unlimited concurrent readers.
+
+2. **Write path**: EVENT inserts go through a single dedicated writer thread. SQLite only allows one writer at a time anyway — this serializes writes cleanly.
+
+3. **Result delivery**: Worker threads cannot call `lws_write()` directly (libwebsockets is not thread-safe). Instead, they push results into a per-session message queue and call `lws_cancel_service()` to wake the event loop, which then drains the queue.
+
+4. **Connection lifecycle**: Each thread opens its own connection with `PRAGMA journal_mode=WAL` and `PRAGMA busy_timeout=5000`.
+
+### What Changes in the Codebase
+
+| Component | Current | Thread Pool |
+|-----------|---------|-------------|
+| [`g_db`](../src/main.c:49) | Single global connection | One per thread + writer connection |
+| [`handle_req_message()`](../src/main.c:1101) | Synchronous SQL in callback | Package filter into job, dispatch to pool |
+| [`store_event()`](../src/main.c:787) | Synchronous INSERT in callback | Dispatch to writer thread |
+| [`handle_count_message()`](../src/websockets.c:2863) | Synchronous COUNT in callback | Dispatch to pool |
+| Result delivery | Direct `queue_message()` | Worker pushes to queue + `lws_cancel_service()` |
+| Config reads | Direct `sqlite3_prepare` on `g_db` | Can stay synchronous with own connection or cache |
+
+### New Files
+
+- `src/thread_pool.h` — Thread pool interface
+- `src/thread_pool.c` — Thread pool implementation (job queue, worker lifecycle, result delivery)
+
+### Thread Pool Interface (sketch)
+
+```c
+// src/thread_pool.h
+#ifndef THREAD_POOL_H
+#define THREAD_POOL_H
+
+typedef enum {
+    JOB_TYPE_REQ_QUERY,
+    JOB_TYPE_COUNT_QUERY,
+    JOB_TYPE_STORE_EVENT,
+    JOB_TYPE_DELETE_EVENT,
+} job_type_t;
+
+typedef struct {
+    job_type_t type;
+    void* session;              // lws per-session data pointer
+    db_event_filter_t filter;   // For REQ/COUNT jobs
+    cJSON* event;               // For STORE jobs
+    char event_id[65];          // For DELETE jobs
+} db_job_t;
+
+int thread_pool_init(int num_readers, const char* db_path);
+void thread_pool_shutdown(void);
+int thread_pool_submit_read(db_job_t* job);
+int thread_pool_submit_write(db_job_t* job);
+
+#endif // THREAD_POOL_H
+```
+
+### Performance Characteristics
+
+| Metric | Value |
+|--------|-------|
+| **Concurrent reads** | N readers in parallel (N = thread count, typically 4–8) |
+| **Write throughput** | Same as current — SQLite serializes writes regardless |
+| **Event loop latency** | Near-zero — REQ no longer blocks the loop |
+| **Max theoretical read throughput** | ~4–8x current (limited by disk I/O, not CPU) |
+| **Memory overhead** | ~50–100 MB per connection (page cache) |
+| **Latency per query** | Same as current per-query, but no head-of-line blocking |
+
+### Limitations
+
+- **Write contention**: SQLite still allows only ONE writer at a time. With WAL, readers don't block writers and writers don't block readers, but two simultaneous writes will serialize. At the current write rate (~56 events/hour), this is a non-issue.
+- **Database size**: The 2.7 GB index bloat problem remains. Thread pool doesn't fix the schema — it fixes the concurrency.
+- **Scaling ceiling**: Beyond ~8 reader threads, diminishing returns due to disk I/O contention on a single SQLite file.
+- **Complexity**: Need a proper job queue, thread lifecycle management, and careful handling of the lws ↔ worker thread boundary.
+
+---
+
+## Risk Mitigation
+
+| Risk | Mitigation |
+|------|-----------|
+| Phase 1 introduces bugs | Each file migrated independently, tested after each. Full test suite runs after each file. |
+| Thread pool race conditions | Worker threads only touch their own `sqlite3*` connection. Result delivery uses a mutex-protected queue. `lws_cancel_service()` is documented as thread-safe. |
+| Performance regression from abstraction | Abstraction layer is thin wrappers — no extra allocations or copies. Benchmark before/after. |
+| lws thread safety issues | Workers never call `lws_write()` directly. They push to a queue and wake the event loop. This is the documented pattern for libwebsockets multi-threading. |
+| Rollback needed | Phase 1 is a pure refactor — easy to revert. Phase 2 thread pool is additive — can be disabled with a compile flag. |
+
+---
+
+## Relationship to c-relay-pg
+
+After Phase 1 (abstraction layer) is complete, the codebase is ready to be forked into a separate **c-relay-pg** project that replaces the SQLite backend with PostgreSQL. See [c-relay-pg plan](c_relay_pg_plan.md) for details.
+
+The `db_ops.h` interface is designed to work with any backend:
+- **SQLite** (this plan): `db_result_next_json()` copies from `sqlite3_column_text()`
+- **PostgreSQL** (c-relay-pg): `db_result_next_json()` returns from `PQgetvalue()`
+- **LMDB** (future possibility): `db_result_next_json()` returns a zero-copy pointer into mmap'd memory

+# Plan: Eliminate g_db from the Main Thread
+
+## Problem Statement
+
+All SQLite calls go through `db_ops.c`, but `db_active_connection()` falls back to `g_db` when `g_thread_db` is NULL. Since the main thread never sets `g_thread_db`, every `db_*` call from lws-main executes synchronous SQLite on the main thread. The thread pool workers have their own connections and work correctly — the problem is the **fallback path**.
+
+Current perf data shows lws-main at **67.6% avg CPU**, dominated by SQLite symbols (`sqlite3BtreeTableMoveto`, `sqlite3VdbeExec`, `pcache1Fetch`).
+
+## Goal
+
+Remove `g_db` as a runtime connection used by the main thread. After this change:
+- The main thread has **no SQLite connection** and cannot execute synchronous queries
+- All DB work routes through thread pool workers (which have their own connections)
+- `g_db` is only used during startup/shutdown (before/after the event loop)
+- Any accidental `db_*` call from lws-main returns an error instead of silently blocking
+
+## Architecture After Change
+
+```

+  - WebSocket protocol handling
+  - Message parsing/routing
+  - Completion queue draining
+  - NO SQLite access during event loop

+### Category D: Auth rule checks — already use separate connections
+
+These functions in `db_ops.c` open their own temporary read-only connections:

+| `db_is_hash_blacklisted()` | 362 | Opens own connection |
+| `db_is_pubkey_whitelisted()` | 377 | Opens own connection |
+| `db_count_active_whitelist_rules()` | 392 | Opens own connection |
+
+These are already safe — they don't use `g_db`. No change needed.
+
+## Implementation Strategy
+
+### Phase 1: Pre-warm caches and eliminate cache-miss DB reads
+
+1. Pre-warm the config cache at startup by loading all config values into the in-memory cache before the event loop starts
+2. Pre-warm the NIP-11 cache at startup
+3. Pre-warm the auth rules fast cache at startup
+4. This eliminates the most frequent cache-miss `db_get_config_value_dup()` calls
+
+### Phase 2: Route subscription logging through write worker
+
+1. Add a `THREAD_POOL_JOB_FIRE_AND_FORGET` job type to thread_pool
+2. Create async wrappers: `db_log_subscription_created_async()`, etc.
+3. These submit SQL to the write worker queue and return immediately
+4. No completion callback needed — fire and forget
+
+### Phase 3: Route special-kind EVENT store through async worker
+
+1. Remove the `event_is_async_eligible()` exclusion for kinds 14, 1059, 23456
+2. For kind 23456: process admin command in completion handler on main thread after store
+3. For kind 14/1059: process NIP-17 DM in completion handler after store
+
+### Phase 4: Route periodic timer DB work through workers
+
+1. `generate_and_post_status_event()` — submit event creation to write worker
+2. `ip_ban_cleanup()` / `ip_ban_log_stats()` — submit to write worker
+3. Monitoring queries — submit to read worker with completion callback
+
+### Phase 5: Null out g_db before event loop
+
+1. After startup is complete and thread pool is initialized, set `g_db = NULL`
+2. Change `db_active_connection()` to assert/warn if both `g_thread_db` and `g_db` are NULL
+3. Any accidental main-thread DB call will now fail loudly instead of silently blocking
+4. Restore `g_db` briefly for shutdown checkpoint
+
+## Implementation Order
+
+1. Phase 1 — lowest risk, immediate benefit from eliminating cache misses
+2. Phase 2 — straightforward fire-and-forget pattern
+3. Phase 3 — moderate complexity, needs careful completion handler design
+4. Phase 4 — moderate complexity, periodic tasks need async patterns
+5. Phase 5 — the final enforcement step, only safe after phases 1-4
+
+## Risk Assessment
+
+- **Phase 1**: Very low risk — just pre-warming existing caches
+- **Phase 2**: Low risk — subscription logging is non-critical, fire-and-forget is safe
+- **Phase 3**: Medium risk — admin/DM event processing has complex state; needs careful testing
+- **Phase 4**: Medium risk — periodic tasks have side effects that need to complete
+- **Phase 5**: High risk if done prematurely — must verify ALL runtime paths are covered first
+
+## Expected Impact
+
+After all phases:
+- lws-main CPU should drop from ~67% to near 0% SQLite overhead
+- All SQLite work happens on db-read and db-write threads
+- Main thread only does WebSocket I/O, JSON parsing, and completion queue draining
+- Thread model becomes: lws-main = pure I/O, workers = all DB

+# Event JSON Storage & Database Migration Plan
+
+**Goal:** Store full event JSON in database for 2,500x faster retrieval + implement proper database migration system
+
+---
+
+## Decision: Fresh Start vs Migration
+
+### Option A: Fresh Start (Recommended for This Change)
+
+**Pros:**
+- ✅ Clean implementation (no migration complexity)
+- ✅ Fast deployment (no data conversion)
+- ✅ No risk of migration bugs
+- ✅ Opportunity to fix any schema issues
+- ✅ Smaller database (no legacy data)
+
+**Cons:**
+- ❌ Lose existing events
+- ❌ Relay starts "empty"
+- ❌ Historical data lost
+
+**Recommendation:** **Fresh start for this change** because:
+1. Your relay is still in development/testing phase
+2. The schema change is fundamental (affects every event)
+3. Migration would require reconstructing JSON for every existing event (expensive)
+4. You've been doing fresh starts anyway
+
+### Option B: Implement Migration System
+
+**Pros:**
+- ✅ Preserve existing events
+- ✅ No data loss
+- ✅ Professional approach
+- ✅ Reusable for future changes
+
+**Cons:**
+- ❌ Complex implementation
+- ❌ Slow migration (reconstruct JSON for all events)
+- ❌ Risk of bugs during migration
+- ❌ Requires careful testing
+
+**Recommendation:** **Implement migration system for FUTURE changes**, but start fresh for this one.
+
+---
+
+## Proposed Schema Change
+
+### New Schema (v11)
+
+```sql
+CREATE TABLE events (
+    id TEXT PRIMARY KEY,
+    pubkey TEXT NOT NULL,
+    created_at INTEGER NOT NULL,
+    kind INTEGER NOT NULL,
+    event_type TEXT NOT NULL CHECK (event_type IN ('regular', 'replaceable', 'ephemeral', 'addressable')),
+    content TEXT NOT NULL,
+    sig TEXT NOT NULL,
+    tags JSON NOT NULL DEFAULT '[]',
+    event_json TEXT NOT NULL,  -- NEW: Full event as JSON string
+    first_seen INTEGER NOT NULL DEFAULT (strftime('%s', 'now'))
+);
+
+-- Keep all existing indexes (they query the columns, not event_json)
+CREATE INDEX idx_events_pubkey ON events(pubkey);
+CREATE INDEX idx_events_kind ON events(kind);
+CREATE INDEX idx_events_created_at ON events(created_at DESC);
+CREATE INDEX idx_events_kind_created_at ON events(kind, created_at DESC);
+CREATE INDEX idx_events_pubkey_created_at ON events(pubkey, created_at DESC);
+```
+
+### Why Keep Both Columns AND event_json?
+
+**Columns (id, pubkey, kind, etc.):**
+- Used for **querying** (WHERE clauses, indexes)
+- Fast filtering and sorting
+- Required for SQL operations
+
+**event_json:**
+- Used for **retrieval** (SELECT results)
+- Pre-serialized, ready to send
+- Eliminates JSON reconstruction
+
+**This is a common pattern** in high-performance systems (denormalization for read performance).
+
+---
+
+## Implementation Plan
+
+### Phase 1: Schema Update (v11)

+```
+
+### Phase 2: Update store_event() Function
+
+**File:** `src/main.c` (lines 660-773)
+
+**Current:**
+```c
+int store_event(cJSON* event) {
+    // Extract fields
+    cJSON* id = cJSON_GetObjectItem(event, "id");
+    // ... extract other fields ...
+    
+    // INSERT with individual columns
+    const char* sql = "INSERT INTO events (id, pubkey, ...) VALUES (?, ?, ...)";
+}
+```
+
+**New:**
+```c
+int store_event(cJSON* event) {
+    // Serialize event to JSON string ONCE
+    char* event_json = cJSON_PrintUnformatted(event);
+    if (!event_json) {
+        return -1;
+    }
+    
+    // Extract fields for indexed columns
+    cJSON* id = cJSON_GetObjectItem(event, "id");
+    // ... extract other fields ...
+    
+    // INSERT with columns + event_json

+    // ... bind parameters ...
+    sqlite3_bind_text(stmt, 9, event_json, -1, SQLITE_TRANSIENT);
+    
+    // ... execute ...
+    free(event_json);
+}
+```
+
+### Phase 3: Update handle_req_message() Function
+
+**File:** `src/main.c` (lines 1302-1361)
+
+**Current:**
+```c
+while (sqlite3_step(stmt) == SQLITE_ROW) {
+    // Build event JSON from 7 columns
+    cJSON* event = cJSON_CreateObject();
+    cJSON_AddStringToObject(event, "id", (char*)sqlite3_column_text(stmt, 0));
+    // ... 6 more fields ...
+    cJSON* tags = cJSON_Parse(tags_json);  // Parse tags
+    cJSON_AddItemToObject(event, "tags", tags);
+    
+    // Create EVENT message
+    cJSON* event_msg = cJSON_CreateArray();
+    cJSON_AddItemToArray(event_msg, cJSON_CreateString("EVENT"));
+    cJSON_AddItemToArray(event_msg, cJSON_CreateString(sub_id));
+    cJSON_AddItemToArray(event_msg, event);
+    
+    char* msg_str = cJSON_Print(event_msg);
+    queue_message(wsi, pss, msg_str, msg_len, LWS_WRITE_TEXT);
+}
+```
+
+**New:**
+```c
+// Update SQL to select event_json
+const char* sql = "SELECT event_json FROM events WHERE ...";
+
+while (sqlite3_step(stmt) == SQLITE_ROW) {
+    const char* event_json = (char*)sqlite3_column_text(stmt, 0);
+    
+    // Build EVENT message with pre-serialized event
+    // Format: ["EVENT","sub_id",{...event_json...}]
+    size_t msg_len = 12 + strlen(sub_id) + strlen(event_json);  // ["EVENT","",""]
+    char* msg_str = malloc(msg_len + 1);
+    snprintf(msg_str, msg_len + 1, "[\"EVENT\",\"%s\",%s]", sub_id, event_json);
+    
+    queue_message(wsi, pss, msg_str, strlen(msg_str), LWS_WRITE_TEXT);
+    free(msg_str);
+}
+```
+
+**Speedup:** 366 × (cJSON operations) eliminated!

+
+## Recommendation: Hybrid Approach
+
+### For This Change (v10 → v11): Fresh Start
+
+**Rationale:**
+1. Your relay is still in development
+2. Migration would be slow (reconstruct JSON for all events)
+3. You've been doing fresh starts anyway
+4. Clean slate for performance testing
+
+**Steps:**
+1. Update schema to v11 with event_json column
+2. Update store_event() to populate event_json
+3. Update handle_req_message() to use event_json
+4. Deploy with fresh database
+5. Test performance improvement
+
+### For Future Changes: Use Migration System
+
+**Rationale:**
+1. Once relay is in production, data preservation matters
+2. Migration system is reusable
+3. Professional approach for production relay
+
+**Steps:**
+1. Create `src/migrations.c` and `src/migrations.h`
+2. Implement migration framework
+3. Add migration functions for each schema change
+4. Test migrations thoroughly before deployment
+
+---
+
+## Migration System Features
+
+### Core Features
+
+1. **Version Detection**
+   - Read current schema version from database
+   - Compare with embedded schema version
+   - Determine which migrations to run
+
+2. **Migration Chain**
+   - Run migrations in sequence (v8 → v9 → v10 → v11)
+   - Skip already-applied migrations
+   - Stop on first failure
+
+3. **Backup Before Migration**
+   - Automatic database backup before migration
+   - Rollback capability if migration fails
+   - Backup retention policy
+
+4. **Progress Reporting**
+   - Log migration progress
+   - Show estimated time remaining
+   - Report success/failure
+
+### Safety Features
+
+1. **Transaction Wrapping**
+   ```c
+   sqlite3_exec(db, "BEGIN TRANSACTION", NULL, NULL, NULL);
+   int result = migrate_v10_to_v11(db);
+   if (result == 0) {
+       sqlite3_exec(db, "COMMIT", NULL, NULL, NULL);
+   } else {
+       sqlite3_exec(db, "ROLLBACK", NULL, NULL, NULL);
+   }
+   ```
+
+2. **Validation After Migration**
+   - Verify row counts match
+   - Check data integrity
+   - Validate indexes created
+
+3. **Dry-Run Mode**
+   - Test migration without committing
+   - Report what would be changed
+   - Estimate migration time
+

+
+## Implementation Timeline
+
+### Immediate (Today): Fresh Start with event_json
+
+**Changes:**
+1. Update schema to v11 (add event_json column)
+2. Update store_event() to populate event_json

+
+## Testing Strategy
+
+### For Fresh Start (v11)
+
+1. **Local testing:**
+   - Build with new schema
+   - Post test events
+   - Query events and measure performance
+   - Verify event_json is populated correctly
+
+2. **Performance testing:**
+   - Query 366 events
+   - Measure time (should be <10ms instead of 18s)
+   - Check CPU usage (should be <20%)
+
+3. **Production deployment:**
+   - Stop relay
+   - Delete old database
+   - Start relay with v11 schema
+   - Monitor performance
+
+### For Migration System (Future)
+
+1. **Unit tests:**
+   - Test each migration function
+   - Test rollback capability
+   - Test error handling
+
+2. **Integration tests:**
+   - Create database with old schema
+   - Run migration
+   - Verify data integrity
+   - Test rollback
+
+3. **Performance tests:**
+   - Measure migration time for large databases
+   - Test with 10K, 100K, 1M events
+   - Optimize slow migrations
+
+---
+
+## Migration Complexity Analysis
+
+### For v10 → v11 Migration
+
+**If we were to migrate existing data:**
+
+```sql
+-- Step 1: Add column (fast)
+ALTER TABLE events ADD COLUMN event_json TEXT;
+
+-- Step 2: Populate event_json (SLOW!)
+-- For each of N events:
+--   1. SELECT 7 columns
+--   2. Reconstruct JSON (cJSON operations)
+--   3. Serialize to string (cJSON_Print)
+--   4. UPDATE event_json column
+--   5. Free memory
+
+-- Estimated time:
+-- - 1000 events: ~10 seconds
+-- - 10000 events: ~100 seconds
+-- - 100000 events: ~1000 seconds (16 minutes)
+```
+
+**Conclusion:** Migration is expensive for this change. Fresh start is better.
+
+---
+
+## Future Migration Examples
+
+### Easy Migrations (Fast)
+
+**Adding an index:**
+```c
+int migrate_add_index(sqlite3* db) {
+    return sqlite3_exec(db, 
+        "CREATE INDEX idx_new ON events(new_column)",
+        NULL, NULL, NULL);
+}
+```
+
+**Adding a column with default:**
+```c
+int migrate_add_column(sqlite3* db) {
+    return sqlite3_exec(db,
+        "ALTER TABLE events ADD COLUMN new_col TEXT DEFAULT ''",
+        NULL, NULL, NULL);
+}
+```
+
+### Hard Migrations (Slow)
+
+**Changing column type:**
+- Requires table recreation
+- Copy all data
+- Recreate indexes
+- Can take minutes for large databases
+
+**Populating computed columns:**
+- Requires row-by-row processing
+- Can take minutes for large databases
+
+---
+
+## Recommendation Summary
+
+### For This Change (event_json)
+
+**Do:** Fresh start with v11 schema
+- Fast deployment
+- Clean implementation
+- Immediate performance benefit
+- No migration complexity
+
+**Don't:** Migrate existing data
+- Too slow (reconstruct JSON for all events)
+- Too complex (first migration)
+- Not worth it (relay still in development)
+
+### For Future Changes
+
+**Do:** Implement migration system
+- Professional approach
+- Data preservation
+- Reusable framework
+- Required for production relay
+
+**Timeline:**
+- **Today:** Deploy v11 with fresh start
+- **This week:** Build migration framework
+- **Future:** Use migrations for all schema changes
+
+---
+
+## Next Steps
+
+1. ✅ Update schema to v11 (add event_json column)
+2. ✅ Update store_event() to populate event_json
+3. ✅ Update handle_req_message() to use event_json
+4. ✅ Test locally with 366-event query
+5. ✅ Deploy to production with fresh database
+6. ✅ Measure performance improvement
+7. ⏳ Build migration system for future use
+
+**Expected result:** 366-event retrieval time drops from 18s to <10ms (2,500x speedup)

+# Event Tags Denormalization Plan
+
+## Problem Statement
+
+The relay is at 99% CPU with 1,178 WebSocket connections and ~120 new REQ subscriptions per minute. The root cause is that every tag-filtered REQ query (e.g., `#g`, `#e`, `#p`) uses `json_each(json(tags))` with `json_extract()` — a correlated subquery that parses the JSON tags column for every candidate row. With geohash-based subscriptions from a location app generating constant connection churn, this creates unsustainable CPU load.
+
+### Evidence
+
+- `EXPLAIN QUERY PLAN` shows: `CORRELATED SCALAR SUBQUERY → SCAN json_each VIRTUAL TABLE`
+- 8,077 subscription creates/hour but only 442 active at any time (connection churn)
+- Only 56 events stored/hour — the load is entirely from **read queries**, not writes
+- 14,819 events match the kind filter; each query parses JSON tags on candidate rows
+
+## Solution: Denormalized `event_tags` Table
+
+Replace `json_each()` queries with indexed lookups on a separate `event_tags` table. This is the standard approach used by strfry, nostream, and other production Nostr relays.
+
+### Performance Impact
+
+| Metric | Before | After |
+|--------|--------|-------|
+| Tag query type | `json_each()` correlated subquery | Indexed JOIN/subquery |
+| Complexity per query | O(rows × tags_per_event) JSON parsing | O(log n) B-tree lookup |
+| Expected CPU reduction | 99% | <10% for same traffic |
+
+## Files to Modify
+
+| File | Changes |
+|------|---------|
+| `src/sql_schema.h` | Add `event_tags` table, indexes, cascade triggers; bump to schema v12 |
+| `src/main.c` | Add `store_event_tags()`, update `handle_req_message()` tag filter SQL, move config reads out of row loop, add startup tag population |
+| `src/nip009.c` | Add `DELETE FROM event_tags` alongside event deletions |
+| `src/dm_admin.c` | Downgrade NIP-17 decryption failure log level |
+| `src/websockets.c` | Downgrade NIP-17 error log to DEBUG at lines 780 and 1488 |
+
+## Detailed Changes
+
+### 1. Schema: `src/sql_schema.h`
+
+Add the `event_tags` table after the events table definition. Bump schema version to 12.
+
+```sql
+-- Denormalized event tags for fast indexed lookups
+-- Replaces json_each(json(tags)) queries which cause full JSON parsing per row
+CREATE TABLE event_tags (
+    event_id TEXT NOT NULL,
+    tag_name TEXT NOT NULL,
+    tag_value TEXT NOT NULL,
+    tag_index INTEGER NOT NULL DEFAULT 0,
+    FOREIGN KEY (event_id) REFERENCES events(id) ON DELETE CASCADE
+);
+
+-- Primary lookup index: find events by tag name + value
+CREATE INDEX idx_event_tags_lookup ON event_tags(tag_name, tag_value);
+
+-- Reverse lookup: find all tags for an event (for cleanup)
+CREATE INDEX idx_event_tags_event ON event_tags(event_id);
+
+-- Composite index for common query pattern: tag + kind (via join)
+CREATE INDEX idx_event_tags_value_name ON event_tags(tag_value, tag_name);
+```
+
+**Key design decisions:**
+- `ON DELETE CASCADE` handles cleanup when events are deleted (NIP-09, replaceable events)
+- `tag_index` stores the position within the tags array (useful for ordered tag access)
+- Only the first two elements of each tag are indexed (`tag_name` = `$[0]`, `tag_value` = `$[1]`) — this covers all standard Nostr tag filters (`#e`, `#p`, `#t`, `#g`, `#d`, etc.)
+- `PRAGMA foreign_keys = ON` is already in the schema, so CASCADE will work
+
+### 2. Store Tags: `src/main.c` — New `store_event_tags()` Function
+
+Add a new function called after successful event INSERT in `store_event()`:
+
+```c
+// Insert denormalized tags into event_tags table for fast indexed lookups
+int store_event_tags(const char* event_id, cJSON* tags) {
+    if (!g_db || !event_id || !tags || !cJSON_IsArray(tags)) {
+        return 0; // Not an error if no tags
+    }
+
+    const char* sql = "INSERT INTO event_tags (event_id, tag_name, tag_value, tag_index) VALUES (?, ?, ?, ?)";
+    sqlite3_stmt* stmt;
+    int rc = sqlite3_prepare_v2(g_db, sql, -1, &stmt, NULL);
+    if (rc != SQLITE_OK) {
+        DEBUG_ERROR("Failed to prepare event_tags insert: %s", sqlite3_errmsg(g_db));
+        return -1;
+    }
+
+    int tag_index = 0;
+    cJSON* tag = NULL;
+    cJSON_ArrayForEach(tag, tags) {
+        if (cJSON_IsArray(tag) && cJSON_GetArraySize(tag) >= 2) {
+            cJSON* name = cJSON_GetArrayItem(tag, 0);
+            cJSON* value = cJSON_GetArrayItem(tag, 1);
+
+            if (cJSON_IsString(name) && cJSON_IsString(value)) {
+                sqlite3_reset(stmt);
+                sqlite3_bind_text(stmt, 1, event_id, -1, SQLITE_STATIC);
+                sqlite3_bind_text(stmt, 2, cJSON_GetStringValue(name), -1, SQLITE_STATIC);
+                sqlite3_bind_text(stmt, 3, cJSON_GetStringValue(value), -1, SQLITE_STATIC);
+                sqlite3_bind_int(stmt, 4, tag_index);
+
+                rc = sqlite3_step(stmt);
+                if (rc != SQLITE_DONE) {
+                    DEBUG_ERROR("Failed to insert event tag: %s", sqlite3_errmsg(g_db));
+                }
+            }
+        }
+        tag_index++;
+    }
+
+    sqlite3_finalize(stmt);
+    return 0;
+}
+```
+
+**Call site** — in `store_event()` at line ~784, after `monitoring_on_event_stored()`:
+
+```c
+// After successful event storage, insert denormalized tags
+store_event_tags(cJSON_GetStringValue(id), tags);
+```
+
+### 3. Update REQ Query Builder: `src/main.c` — `handle_req_message()`
+
+Replace the `json_each()` tag filter at lines 1243-1270 with an `event_tags` subquery:
+
+**Before** (current code at line 1244):
+```c
+snprintf(sql_ptr, remaining, 
+    " AND EXISTS (SELECT 1 FROM json_each(json(tags)) "
+    "WHERE json_extract(value, '$[0]') = ? "
+    "AND json_extract(value, '$[1]') IN (");
+```
+
+**After** (new code):
+```c
+snprintf(sql_ptr, remaining,
+    " AND id IN (SELECT event_id FROM event_tags "
+    "WHERE tag_name = ? AND tag_value IN (");
+```
+
+The rest of the parameter binding code (lines 1248-1270) stays the same — the bind params are identical (`tag_name` then `tag_value(s)`). Only the SQL template changes.
+
+The closing parenthesis changes from `"))` to `"))` — same syntax, just different semantics.
+
+### 4. NIP-09 Delete Cascade: `src/nip009.c`
+
+The `ON DELETE CASCADE` foreign key handles this automatically. When `DELETE FROM events WHERE id = ?` executes, SQLite will automatically delete matching rows from `event_tags`. **No code changes needed in nip009.c** as long as `PRAGMA foreign_keys = ON` is set (it already is in the schema).
+
+However, verify the replaceable/addressable event triggers in the schema also cascade properly. The existing triggers at schema lines 97-119 use `DELETE FROM events WHERE ...` which will trigger the CASCADE.
+
+### 5. Performance Fix: Move Config Reads Out of Row Loop
+
+In `handle_req_message()` at lines 1400-1401, `get_config_bool()` is called **inside the `while (sqlite3_step())` loop** — meaning it executes a SQLite query for every row returned. Move these before the loop:
+
+**Before** (inside loop):
+```c
+while (sqlite3_step(stmt) == SQLITE_ROW) {
+    // ...
+    int expiration_enabled = get_config_bool("expiration_enabled", 1);  // SQLite query per row!
+    int filter_responses = get_config_bool("expiration_filter", 1);     // SQLite query per row!
+```
+
+**After** (before loop):
+```c
+int expiration_enabled = get_config_bool("expiration_enabled", 1);
+int filter_responses = get_config_bool("expiration_filter", 1);
+
+while (sqlite3_step(stmt) == SQLITE_ROW) {
+    // ... use cached values
+```
+
+### 6. Log Level Fixes
+
+#### NIP-17 Decryption Failure — `src/websockets.c` lines 780 and 1488
+
+Change from `DEBUG_ERROR` to `DEBUG_INFO`:
+```c
+// Before:
+DEBUG_ERROR("NIP-17 admin message processing failed");
+// After:
+DEBUG_INFO("NIP-17 admin message processing failed");
+```
+
+This is expected behavior when non-admin gift wraps arrive — not an error condition.
+
+#### Duplicate Event INSERT — `src/main.c` line 741
+
+The `DEBUG_ERROR` at line 741 fires before the CONSTRAINT check at line 746. Suppress it for constraint violations:
+
+```c
+// Before (line 738-741):
+if (rc != SQLITE_DONE) {
+    const char* err_msg = sqlite3_errmsg(g_db);
+    int extended_errcode = sqlite3_extended_errcode(g_db);
+    DEBUG_ERROR("INSERT failed: rc=%d, extended_errcode=%d, msg=%s", rc, extended_errcode, err_msg);
+}
+
+// After:
+if (rc != SQLITE_DONE) {
+    const char* err_msg = sqlite3_errmsg(g_db);
+    int extended_errcode = sqlite3_extended_errcode(g_db);
+    if (rc != SQLITE_CONSTRAINT) {
+        DEBUG_ERROR("INSERT failed: rc=%d, extended_errcode=%d, msg=%s", rc, extended_errcode, err_msg);
+    }
+}
+```
+
+### 7. Startup Tag Population
+
+Since you said no migration code is needed (fresh deploy), the `event_tags` table will start empty and populate as new events arrive. Existing events won't have tags in the lookup table.
+
+However, to avoid a period where old events don't appear in tag-filtered queries, add a one-time population function that runs at startup:
+
+```c
+// Populate event_tags from existing events (run once at startup)
+int populate_event_tags_from_existing(void) {
+    if (!g_db) return -1;
+
+    // Check if event_tags is already populated
+    sqlite3_stmt* check_stmt;
+    sqlite3_prepare_v2(g_db, "SELECT COUNT(*) FROM event_tags", -1, &check_stmt, NULL);
+    if (sqlite3_step(check_stmt) == SQLITE_ROW && sqlite3_column_int(check_stmt, 0) > 0) {
+        sqlite3_finalize(check_stmt);
+        DEBUG_INFO("event_tags already populated, skipping");
+        return 0;
+    }
+    sqlite3_finalize(check_stmt);
+
+    DEBUG_INFO("Populating event_tags from existing events...");
+
+    const char* sql = "SELECT id, tags FROM events WHERE tags != '[]'";
+    sqlite3_stmt* stmt;
+    int rc = sqlite3_prepare_v2(g_db, sql, -1, &stmt, NULL);
+    if (rc != SQLITE_OK) return -1;
+
+    // Use a transaction for bulk insert performance
+    sqlite3_exec(g_db, "BEGIN TRANSACTION", NULL, NULL, NULL);
+
+    int event_count = 0;
+    while (sqlite3_step(stmt) == SQLITE_ROW) {
+        const char* event_id = (const char*)sqlite3_column_text(stmt, 0);
+        const char* tags_json = (const char*)sqlite3_column_text(stmt, 1);
+
+        if (event_id && tags_json) {
+            cJSON* tags = cJSON_Parse(tags_json);
+            if (tags) {
+                store_event_tags(event_id, tags);
+                cJSON_Delete(tags);
+                event_count++;
+            }
+        }
+    }
+
+    sqlite3_finalize(stmt);
+    sqlite3_exec(g_db, "COMMIT", NULL, NULL, NULL);
+
+    DEBUG_INFO("Populated event_tags for %d events", event_count);
+    return 0;
+}
+```
+
+Call this during startup, after database initialization but before accepting connections.

+
+## Testing Strategy
+
+1. Run existing test suite: `tests/run_all_tests.sh`
+2. Specifically run NIP tests that use tag filters: `tests/run_nip_tests.sh`
+3. Verify tag-filtered REQ queries return correct results
+4. Verify NIP-09 deletion cascades to event_tags
+5. Verify replaceable event triggers cascade to event_tags
+6. Monitor CPU usage after deployment with same traffic pattern
+
+## Risk Assessment
+
+- **Low risk**: The `event_tags` table is additive — it doesn't change the events table structure
+- **Low risk**: `ON DELETE CASCADE` is a well-tested SQLite feature
+- **Low risk**: The SQL change in `handle_req_message()` is a drop-in replacement (same bind params)
+- **Medium risk**: Startup population on a large database could take a few seconds — but with only 55K events, this should complete in under 1 second
+- **Write overhead**: Each event INSERT now also inserts ~5 rows into event_tags — negligible at 56 events/hour

+# Plan: Ban Idle and Early-Disconnect Connections
+
+## Problem Statement
+
+The relay needs to defend against spam connections that:
+1. Connect via WebSocket and sit idle doing nothing (the original problem)
+2. Connect and immediately disconnect without subscribing or posting (the new requirement)
+
+Both patterns indicate bot/scanner behavior that should result in IP bans.
+
+## Goal
+
+Implement a system that:
+- Bans IPs that connect but never send a REQ or EVENT (regardless of how the connection ends)
+- Works **independent of NIP-42 authentication** (no auth required)
+- Allows legitimate users to connect and use the relay normally
+- Uses existing IP ban infrastructure
+
+## Architecture Overview
+
+```mermaid
+flowchart TD
+    A[Client connects] --> B{IP banned?}
+    B -->|Yes| C[Reject immediately]
+    B -->|No| D[Set idle timeout timer]
+    D --> E{Client sends REQ or EVENT?}
+    E -->|Yes| F[Mark session ACTIVE<br>Cancel idle timer]
+    E -->|No| G{Connection closes?}
+    G --> H{Session was ACTIVE?}
+    H -->|Yes| I[Clean close - no ban]
+    H -->|No| J["ip_ban_record_failure()<br>→ may trigger ban"]
+    F --> K[Normal operation]
+    K --> L[Connection closes]
+    L --> I
+```
+
+## Key Insight
+
+The distinction between "idle timeout" and "early disconnect" is minimal:
+- **Idle timeout**: Connection closed by server because client never became ACTIVE
+- **Early disconnect**: Connection closed by client because client never became ACTIVE
+
+Both result in the same check: `if (!session_was_active) ban_ip()`
+
+## Implementation Plan
+
+### 1. Add Session Activity Tracking
+
+**File: `src/websockets.h`**
+
+Add to `struct per_session_data`:
+
+```c
+// Session activity tracking for idle connection banning
+int session_active;           // 1 if client sent REQ or EVENT, 0 otherwise
+int idle_timeout_sec;         // Timeout value for this session (copied from config)
+```
+
+### 2. Set Idle Timeout on All Connections
+
+**File: `src/websockets.c` - `LWS_CALLBACK_ESTABLISHED`**
+
+Currently (lines 561-572):
+```c
+// Only set timeout if auth is required
+if (pss->nip42_auth_required_events || pss->nip42_auth_required_subscriptions) {
+    int auth_timeout = get_config_int("nip42_auth_timeout_sec", 10);
+    if (auth_timeout > 0) {
+        lws_set_timeout(wsi, PENDING_TIMEOUT_AWAITING_PING, auth_timeout);
+    }
+}
+```
+
+Change to:
+```c
+// Initialize session activity tracking
+pss->session_active = 0;
+pss->idle_timeout_sec = get_config_int("idle_connection_timeout_sec", 30);
+
+// Set idle timeout for ALL connections (not just auth-required)
+// This catches bots that connect and do nothing
+if (pss->idle_timeout_sec > 0) {
+    lws_set_timeout(wsi, PENDING_TIMEOUT_AWAITING_PING, pss->idle_timeout_sec);
+    DEBUG_TRACE("Idle timeout set: %d seconds for connection from %s",
+                pss->idle_timeout_sec, pss->client_ip);
+}
+
+// Also set auth timeout if auth is required (separate concern)
+if (pss->nip42_auth_required_events || pss->nip42_auth_required_subscriptions) {
+    int auth_timeout = get_config_int("nip42_auth_timeout_sec", 10);
+    // Use the shorter of the two timeouts
+    int effective_timeout = (pss->idle_timeout_sec > 0 && pss->idle_timeout_sec < auth_timeout) 
+                            ? pss->idle_timeout_sec 
+                            : auth_timeout;
+    if (effective_timeout > 0) {
+        lws_set_timeout(wsi, PENDING_TIMEOUT_AWAITING_PING, effective_timeout);
+    }
+}
+```
+
+### 3. Mark Session as Active on Valid Activity
+
+**File: `src/websockets.c` - `LWS_CALLBACK_RECEIVE`**
+
+When processing REQ message (around line 1030):
+```c
+// Before handling REQ, mark session as active
+pthread_mutex_lock(&pss->session_lock);
+pss->session_active = 1;
+pthread_mutex_unlock(&pss->session_lock);
+
+// Cancel idle timeout - this is legitimate usage
+lws_set_timeout(wsi, NO_PENDING_TIMEOUT, 0);
+```
+
+When processing EVENT message (around line 1380):
+```c
+// Before handling EVENT, mark session as active
+pthread_mutex_lock(&pss->session_lock);
+pss->session_active = 1;
+pthread_mutex_unlock(&pss->session_lock);
+
+// Cancel idle timeout - this is legitimate usage
+lws_set_timeout(wsi, NO_PENDING_TIMEOUT, 0);
+```
+
+**Note**: We should also consider AUTH as "activity" since the client is engaging with the protocol:
+```c
+// In handle_nip42_auth_signed_event (nip042.c)
+// After successful auth, also mark session active
+pthread_mutex_lock(&pss->session_lock);
+pss->session_active = 1;
+pthread_mutex_unlock(&pss->session_lock);
+```
+
+### 3.5. Separate Rate Limiting for Idle Connections
+
+Per user feedback, idle/early-disconnect failures have **separate rate limiting** from auth failures. This requires:
+
+**New Config Keys:**
+
+| Config Key | Type | Default | Range | Description |
+|------------|------|---------|-------|-------------|
+| `idle_ban_threshold` | int | 3 | 1-100 | Idle failures before ban |
+| `idle_ban_window_sec` | int | 60 | 10-3600 | Window for counting idle failures |
+| `idle_ban_duration_sec` | int | 300 | 60-86400 | Initial idle ban duration |
+
+**Add to `ip_ban_entry_t` in `src/ip_ban.c`:**
+
+```c
+typedef struct {
+    int state;
+    char ip[46];
+    
+    // Auth failure tracking (existing)
+    int failure_count;
+    time_t first_failure;
+    time_t banned_until;
+    int ban_count;
+    
+    // NEW: Idle failure tracking (separate)
+    int idle_failure_count;
+    time_t idle_first_failure;
+    time_t idle_banned_until;
+    int idle_ban_count;
+    
+    // Other existing fields...
+    int has_authed_successfully;
+    time_t last_success_at;
+    int total_connections;
+    int total_failures;
+    int total_successes;
+    time_t first_seen;
+} ip_ban_entry_t;
+```
+
+**New function in `src/ip_ban.c`:**
+
+```c
+// Record an idle/early-disconnect failure for an IP
+void ip_ban_record_idle_failure(const char* ip) {
+    if (!ip || !g_initialized) return;
+    if (!get_config_bool("idle_ban_enabled", 1)) return;
+
+    int threshold = get_config_int("idle_ban_threshold", 3);
+    int window_sec = get_config_int("idle_ban_window_sec", 60);
+    int ban_duration = get_config_int("idle_ban_duration_sec", 300);
+
+    pthread_mutex_lock(&g_ban_mutex);
+    ip_ban_entry_t* entry = get_or_create_entry(ip);
+    if (!entry) {
+        pthread_mutex_unlock(&g_ban_mutex);
+        return;
+    }
+
+    time_t now = time(NULL);
+
+    // Reset window if expired
+    if (entry->idle_first_failure > 0 && (now - entry->idle_first_failure) > window_sec) {
+        entry->idle_failure_count = 0;
+        entry->idle_first_failure = now;
+    }
+    if (entry->idle_first_failure == 0) {
+        entry->idle_first_failure = now;
+    }
+
+    entry->idle_failure_count++;
+    entry->total_failures++;
+
+    DEBUG_TRACE("IP %s idle failure count: %d/%d", ip, entry->idle_failure_count, threshold);
+
+    if (entry->idle_failure_count >= threshold) {
+        int duration = ban_duration;
+        for (int i = 0; i < entry->idle_ban_count && duration < 86400; i++) {
+            duration *= 2;
+        }
+        if (duration > 86400) duration = 86400;
+
+        entry->idle_banned_until = now + duration;
+        entry->idle_ban_count++;
+        entry->idle_failure_count = 0;
+        entry->idle_first_failure = 0;
+
+        DEBUG_WARN("IP %s banned for %d seconds (idle ban #%d) after %d idle failures",
+                   ip, duration, entry->idle_ban_count, threshold);
+    }
+
+    pthread_mutex_unlock(&g_ban_mutex);
+}
+```
+
+**Update `ip_ban_is_banned()` to check BOTH ban types:**
+
+```c
+int ip_ban_is_banned(const char* ip) {
+    if (!ip || !g_initialized) return 0;
+    
+    pthread_mutex_lock(&g_ban_mutex);
+    int idx = find_slot(ip);
+    if (idx < 0 || g_ban_table[idx].state == IP_BAN_EMPTY) {
+        pthread_mutex_unlock(&g_ban_mutex);
+        return 0;
+    }
+
+    ip_ban_entry_t* entry = &g_ban_table[idx];
+    time_t now = time(NULL);
+    int banned = 0;
+
+    // Check auth ban (if enabled)
+    if (get_config_bool("auth_fail_ban_enabled", 1) &&
+        entry->banned_until > 0 && now < entry->banned_until) {
+        banned = 1;
+    }
+    
+    // Check idle ban (if enabled)
+    if (get_config_bool("idle_ban_enabled", 1) &&
+        entry->idle_banned_until > 0 && now < entry->idle_banned_until) {
+        banned = 1;
+    }
+    
+    // Clear expired bans
+    if (!banned) {
+        if (entry->banned_until > 0 && now >= entry->banned_until) {
+            entry->banned_until = 0;
+            entry->failure_count = 0;
+            entry->first_failure = 0;
+        }
+        if (entry->idle_banned_until > 0 && now >= entry->idle_banned_until) {
+            entry->idle_banned_until = 0;
+            entry->idle_failure_count = 0;
+            entry->idle_first_failure = 0;
+        }
+    }
+
+    pthread_mutex_unlock(&g_ban_mutex);
+    return banned;
+}
+```
+
+**Update persistence:**
+- `ip_ban_load_from_db()`: Load idle_* fields from new columns
+- `ip_ban_save_to_db()`: Save idle_* fields to new columns
+- Add migration SQL to create new columns if they don't exist
+
+**Add to `src/ip_ban.h`:**
+
+```c
+// Record an idle/early-disconnect failure for an IP
+void ip_ban_record_idle_failure(const char* ip);
+```
+
+### 4. Record Failure on Inactive Connection Close
+
+**File: `src/websockets.c` - `LWS_CALLBACK_CLOSED`**
+
+Currently (lines 2121-2128):
+```c
+// Record auth failure if connection closed while unauthenticated and auth was required
+if (!pss->authenticated &&
+    (pss->nip42_auth_required_events || pss->nip42_auth_required_subscriptions) &&
+    pss->auth_challenge_sent &&
+    strlen(pss->client_ip) > 0) {
+    ip_ban_record_failure(pss->client_ip);
+}
+```
+
+Change to:
+```c
+// Record failure if connection closed without ever becoming active
+// This catches:
+// 1. Idle connections that timed out (never sent REQ/EVENT/AUTH)
+// 2. Early disconnects (client closed before sending REQ/EVENT/AUTH)
+if (!pss->session_active && strlen(pss->client_ip) > 0) {

+    ip_ban_record_idle_failure(pss->client_ip);
+    DEBUG_LOG("Recording idle/early-disconnect failure for IP %s (connected %ld seconds)",
+              pss->client_ip,
+              time(NULL) - pss->connection_established);
+}
+// Legacy: record auth failure if auth was required but not completed
+else if (!pss->authenticated &&

+         strlen(pss->client_ip) > 0) {
+    ip_ban_record_failure(pss->client_ip);
+}
+```
+
+### 5. Add Configuration Keys
+
+**File: `src/config.c` - Add validation for new keys**
+
+In the config validation section, add:
+
+```c
+// Idle connection ban settings
+if (strcmp(key, "idle_connection_timeout_sec") == 0) {
+    if (!is_valid_positive_integer(value)) {
+        snprintf(error_msg, error_size, "invalid idle_connection_timeout_sec '%s' (must be positive integer)", value);
+        return -1;
+    }
+    int timeout = atoi(value);
+    if (timeout < 5 || timeout > 300) {
+        snprintf(error_msg, error_size, "idle_connection_timeout_sec must be between 5 and 300 seconds");
+        return -1;
+    }
+    return 0;
+}
+
+if (strcmp(key, "idle_ban_enabled") == 0) {
+    if (!is_valid_boolean(value)) {
+        snprintf(error_msg, error_size, "invalid boolean value '%s' for idle_ban_enabled", value);
+        return -1;
+    }
+    return 0;
+}
+
+if (strcmp(key, "idle_ban_threshold") == 0) {

+        return -1;
+    }
+    int threshold = atoi(value);
+    if (threshold < 1 || threshold > 100) {
+        snprintf(error_msg, error_size, "idle_ban_threshold must be between 1 and 100");
+        return -1;
+    }
+    return 0;
+}
+
+if (strcmp(key, "idle_ban_window_sec") == 0) {
+    if (!is_valid_positive_integer(value)) {

+    int window = atoi(value);
+    if (window < 10 || window > 3600) {
+        snprintf(error_msg, error_size, "idle_ban_window_sec must be between 10 and 3600");
+        return -1;
+    }
+    return 0;
+}
+
+if (strcmp(key, "idle_ban_duration_sec") == 0) {

+        return -1;
+    }
+    return 0;
+}
+```
+
+Also update the config introspection/documentation functions to describe these keys.
+
+### 6. Add API Documentation
+
+**File: `src/api.c` - Add to config metadata**
+
+```c
+{"idle_connection_timeout_sec", "int", 5, 300},
+{"idle_ban_enabled", "bool", 0, 1},
+{"idle_ban_threshold", "int", 1, 100},
+{"idle_ban_window_sec", "int", 10, 3600},
+{"idle_ban_duration_sec", "int", 60, 86400},
+```
+
+Add descriptions in the config query handler:
+```c
+} else if (strcmp(key, "idle_connection_timeout_sec") == 0) {
+    description = "Seconds before an idle connection (no REQ/EVENT) is closed and IP flagged. 0 to disable.";
+} else if (strcmp(key, "idle_ban_enabled") == 0) {
+    description = "Whether to ban IPs that repeatedly connect without sending REQ or EVENT.";
+} else if (strcmp(key, "idle_ban_threshold") == 0) {
+    description = "Number of idle/early-disconnect failures before banning an IP.";

+
+### 7. Update ip_ban Persistence and Cleanup
+
+**File: `src/ip_ban.c` - Update `ip_ban_load_from_db()`**
+
+Add migration SQL to create new columns if they don't exist, then load them:
+```sql
+ALTER TABLE ip_bans ADD COLUMN idle_failure_count INTEGER NOT NULL DEFAULT 0;
+ALTER TABLE ip_bans ADD COLUMN idle_ban_count INTEGER NOT NULL DEFAULT 0;
+ALTER TABLE ip_bans ADD COLUMN idle_banned_until INTEGER NOT NULL DEFAULT 0;
+ALTER TABLE ip_bans ADD COLUMN idle_first_failure INTEGER NOT NULL DEFAULT 0;
+```
+
+**File: `src/ip_ban.c` - Update `ip_ban_save_to_db()`**
+
+Add the idle_* fields to the INSERT/REPLACE statement.
+
+**File: `src/ip_ban.c` - Update `ip_ban_cleanup()`**
+
+Add cleanup logic for idle ban entries (same pattern as auth ban cleanup).
+
+**File: `src/ip_ban.c` - Update `ip_ban_log_stats()`**
+
+Add idle ban count to the periodic log summary:
+```c
+DEBUG_WARN("IP BAN SUMMARY: %d auth-banned, %d idle-banned, %d tracked, %d trusted",
+           auth_banned_count, idle_banned_count, tracked_count, trusted_count);
+```
+
+## Configuration Reference
+
+### Idle Connection Settings
+
+| Config Key | Type | Default | Range | Description |
+|------------|------|---------|-------|-------------|
+| `idle_connection_timeout_sec` | int | 30 | 5-300 | Seconds to wait for REQ/EVENT before closing connection. 0 = disable idle timeout. |
+| `idle_ban_enabled` | bool | true | true/false | Whether to ban IPs with repeated idle/early-disconnect failures. |
+| `idle_ban_threshold` | int | 3 | 1-100 | Idle failures before ban. |
+| `idle_ban_window_sec` | int | 60 | 10-3600 | Window for counting idle failures. |
+| `idle_ban_duration_sec` | int | 300 | 60-86400 | Initial idle ban duration. |
+
+### Auth Failure Settings (Existing)
+
+| Config Key | Type | Default | Range | Description |
+|------------|------|---------|-------|-------------|
+| `auth_fail_ban_enabled` | bool | true | true/false | Whether to ban IPs with failed auth. |
+| `auth_fail_ban_threshold` | int | 3 | 1-100 | Auth failures before ban. |
+| `auth_fail_window_sec` | int | 60 | 10-3600 | Window for counting auth failures. |
+| `auth_fail_ban_duration_sec` | int | 300 | 60-86400 | Initial auth ban duration. |
+
+## Behavior Matrix
+
+| Scenario | idle_timeout_sec | idle_ban_enabled | Result |
+|----------|------------------|------------------|--------|
+| Connect → do nothing → timeout | >0 | true | Connection closed, IP failure recorded, may be banned |
+| Connect → do nothing → timeout | >0 | false | Connection closed, no ban |
+| Connect → immediate disconnect | any | true | IP failure recorded, may be banned |
+| Connect → immediate disconnect | any | false | No ban |
+| Connect → send REQ | any | any | Session active, no ban |
+| Connect → send EVENT | any | any | Session active, no ban |
+| Connect → send AUTH (NIP-42) | any | any | Session active, no ban |
+
+## Testing Strategy
+
+1. **Idle timeout test**: Connect via wscat, wait 30 seconds, verify disconnect and ban table entry
+2. **Early disconnect test**: Connect via wscat, immediately Ctrl-C, verify ban table entry
+3. **Active session test**: Connect, send REQ, disconnect immediately, verify NO ban
+4. **Config disable test**: Set `idle_ban_enabled=false`, repeat test 1, verify no ban
+5. **Timeout config test**: Set `idle_connection_timeout_sec=5`, verify faster disconnect
+
+## Files to Modify
+
+| File | Change Type |
+|------|-------------|
+| `src/websockets.h` | Add `session_active` and `idle_timeout_sec` fields to `per_session_data` |
+| `src/websockets.c` ~565 | Set idle timeout on ALL connections in `LWS_CALLBACK_ESTABLISHED` |
+| `src/websockets.c` ~1030 | Mark `session_active=1` and cancel idle timer on REQ |
+| `src/websockets.c` ~1380 | Mark `session_active=1` and cancel idle timer on EVENT |
+| `src/websockets.c` ~2121 | Call `ip_ban_record_idle_failure()` for inactive sessions in `LWS_CALLBACK_CLOSED` |
+| `src/nip042.c` ~130 | Mark `session_active=1` on successful AUTH |
+| `src/ip_ban.h` | Add `ip_ban_record_idle_failure()` declaration |
+| `src/ip_ban.c` | Add idle_* fields to `ip_ban_entry_t`, new `ip_ban_record_idle_failure()` function, update `ip_ban_is_banned()` to check both ban types, update persistence and cleanup |
+| `src/config.c` ~987+ | Add validation for 5 new idle_* config keys |
+| `src/api.c` ~664 | Add config metadata entries for idle_* keys |
+
+## Deployment on Existing Server
+
+### Config Keys: No Manual SQL Required
+
+All config keys use [`get_config_int()`](src/config.c:300) and [`get_config_bool()`](src/config.c:313) which return **hardcoded defaults** when a key doesn't exist in the config table. The new code will work immediately with these defaults:
+
+- `idle_connection_timeout_sec` → defaults to 30
+- `idle_ban_enabled` → defaults to true
+- `idle_ban_threshold` → defaults to 3
+- `idle_ban_window_sec` → defaults to 60
+- `idle_ban_duration_sec` → defaults to 300
+
+If you want to **override** any defaults, you can insert them into the config table. From the same directory as the `.db` file:
+
+```bash
+# Find your database file
+DB_FILE=$(ls *.db | head -1)
+
+# Optional: Insert custom values (only if you want non-default settings)
+sqlite3 "$DB_FILE" "INSERT OR REPLACE INTO config (key, value) VALUES ('idle_connection_timeout_sec', '30');"
+sqlite3 "$DB_FILE" "INSERT OR REPLACE INTO config (key, value) VALUES ('idle_ban_enabled', 'true');"
+sqlite3 "$DB_FILE" "INSERT OR REPLACE INTO config (key, value) VALUES ('idle_ban_threshold', '3');"
+sqlite3 "$DB_FILE" "INSERT OR REPLACE INTO config (key, value) VALUES ('idle_ban_window_sec', '60');"
+sqlite3 "$DB_FILE" "INSERT OR REPLACE INTO config (key, value) VALUES ('idle_ban_duration_sec', '300');"
+```
+
+Or change them via the admin API/web UI after deployment.
+
+### ip_bans Table: Automatic Migration
+
+The `ip_bans` table needs 4 new columns for idle tracking. The updated [`ip_ban_load_from_db()`](src/ip_ban.c:93) will run `ALTER TABLE` statements automatically on startup. These are safe because SQLite's `ALTER TABLE ADD COLUMN` is a no-op if the column already exists (we'll use error-tolerant execution).
+
+If you prefer to run the migration manually before deploying:
+
+```bash
+DB_FILE=$(ls *.db | head -1)
+
+sqlite3 "$DB_FILE" <<'SQL'
+ALTER TABLE ip_bans ADD COLUMN idle_failure_count INTEGER NOT NULL DEFAULT 0;
+ALTER TABLE ip_bans ADD COLUMN idle_ban_count INTEGER NOT NULL DEFAULT 0;
+ALTER TABLE ip_bans ADD COLUMN idle_banned_until INTEGER NOT NULL DEFAULT 0;
+ALTER TABLE ip_bans ADD COLUMN idle_first_failure INTEGER NOT NULL DEFAULT 0;
+SQL
+```
+
+**Note:** SQLite will error on `ALTER TABLE ADD COLUMN` if the column already exists, but the code will handle this gracefully (ignore the error). Running it manually is optional — the relay will do it on startup.
+
+### Deployment Steps
+
+1. Build and deploy with `deploy_lt.sh` as usual
+2. The relay starts, `ip_ban_load_from_db()` auto-migrates the `ip_bans` table
+3. Config keys use defaults immediately — no manual SQL needed
+4. Optionally tune settings via admin API or direct SQL
+
+## Backward Compatibility
+
+- Default `idle_connection_timeout_sec=30` provides immediate protection
+- Default `idle_ban_enabled=true` maintains current spam protection behavior
+- Setting `idle_connection_timeout_sec=0` restores old behavior (no idle timeout)
+- Setting `idle_ban_enabled=false` allows connections without banning (for debugging)
+- Existing auth-based banning continues to work independently with its own thresholds
+- Database migration adds new columns with defaults — existing ban data preserved
+
+## Summary
+
+This plan implements a unified "session activity" tracking system with **separate rate limiting** for idle vs auth failures:
+
+1. **Catches idle connections** via `lws_set_timeout()` on ALL connections (not just auth-required)
+2. **Catches early disconnects** via the same `!session_active` check on close
+3. **Respects legitimate users** who actually use the relay (REQ/EVENT/AUTH marks session active)
+4. **Separate idle ban tracking** — idle failures have their own threshold, window, and duration independent of auth failures
+5. **Extends existing ban infrastructure** — adds idle_* fields to `ip_ban_entry_t`, unified `ip_ban_is_banned()` checks both ban types
+6. **Fully configurable** — 5 new config keys for idle banning, all tunable via admin events
+
+The key insight is that there's no meaningful difference between "idle timeout" and "early disconnect" — both indicate a client that connected but never actually used the relay. The same `!session_active` check handles both cases, and the separate rate limiting ensures idle bots don't interfere with auth failure tracking for legitimate clients who fail NIP-42.

+# Main Thread CPU Offload Plan
+
+## Problem Statement
+
+The main `c_relay` thread consumes ~56% CPU while the DB worker threads (`db-read-1..4`, `db-write`) sit near 0%. All protocol handling, JSON parsing, event validation, subscription matching, and message queueing happens synchronously inside `nostr_relay_callback()` on the main libwebsockets event-loop thread.
+
+## Current Architecture
+
+```mermaid
+flowchart TD

+    WRITEABLE --> DRAIN[process_message_queue - lws_write]
+```
+
+### Why the main thread is hot
+
+| Work item | Where | Cost |
+|-----------|-------|------|
+| JSON parsing | `cJSON_Parse` in `LWS_CALLBACK_RECEIVE` | Medium - per message |
+| Signature verification | `nostr_validate_unified_request` - ed25519 crypto | **High** - per EVENT |
+| SQL query building | `handle_req_message` filter-to-SQL loop | Low-Medium |
+| Sync DB wait | `thread_pool_execute_*_sync` - pthread_cond_wait | Blocks but yields CPU |
+| Result iteration + expiration check | Row loop in `handle_req_message` with `cJSON_Parse` per row | Medium-High for large result sets |
+| Subscription matching | `broadcast_event_to_subscriptions` - filter matching | Medium - scales with subscriber count |
+| Message serialization + queueing | `snprintf` + `queue_message_take_ownership` per subscriber | Medium |
+| Config lookups | `get_config_int/bool` called repeatedly in hot paths | Low but frequent |
+
+### Key constraint: libwebsockets is single-threaded
+
+libwebsockets requires that **all `lws_write`, `lws_callback_on_writable`, and `lws_close_reason` calls happen from the service thread** (the thread running `lws_service`). This means we cannot directly write to WebSocket connections from worker threads. However, we **can** do computation on worker threads and post results back to the main thread for I/O.
+
+## Offload Strategy
+
+### Phase 1: Async EVENT Processing (Highest Impact)
+
+Convert EVENT handling from synchronous to async. Currently the main thread does: parse → validate → store → broadcast, all blocking. Instead:
+
+1. **Main thread**: Parse JSON (fast), extract event ID for dedup check, then submit a job to a new "event processing" worker thread
+2. **Worker thread**: Signature verification (expensive crypto), store_event (already goes to DB thread), prepare broadcast payload
+3. **Main thread callback**: Receive result via `wake_loop_cb` + `lws_cancel_service`, send OK response and broadcast to subscribers
+
+```mermaid
+flowchart TD
+    LWS[lws_service - main thread] --> RECEIVE[LWS_CALLBACK_RECEIVE]
+    RECEIVE --> PARSE[JSON parse + dedup check]
+    PARSE --> SUBMIT[Submit to event-worker queue]
+    SUBMIT --> LWS
+    
+    WORKER[event-worker thread] --> VERIFY[Signature verification]
+    VERIFY --> STORE_DB[store_event via DB pool]
+    STORE_DB --> PREP[Prepare broadcast payload]
+    PREP --> RESULT_Q[Push result to completion queue]
+    RESULT_Q --> WAKE[lws_cancel_service]
+    
+    LWS2[lws_service wakes] --> POLL[Poll completion queue]
+    POLL --> OK[Send OK response via queue_message]
+    POLL --> BCAST[broadcast_event_to_subscriptions]
+```
+
+**What this offloads**: ed25519 signature verification (~the most expensive per-event operation), event classification, tag serialization, and the synchronous DB store wait.
+
+**What stays on main thread**: JSON parse (needed to extract event ID for dedup), OK response writing, broadcast fan-out (requires lws access).
+
+### Phase 2: Async REQ Query Execution (Medium Impact)
+
+Convert REQ handling from sync to async:
+
+1. **Main thread**: Parse filters, build SQL, create subscription, submit query job
+2. **DB reader thread**: Execute query (already happens, but currently blocks main thread via `_sync`)
+3. **Main thread callback**: Iterate results, queue EVENT messages, send EOSE
+
+This is simpler than Phase 1 because the thread pool already supports async submission via `thread_pool_submit_read` with a `result_cb`. The `_sync` wrappers just add a condvar wait on top. We need to:
+- Use `thread_pool_submit_read` directly instead of `thread_pool_execute_req_sync`
+- Store pending REQ context (sub_id, wsi, pss) so the callback can complete the work
+- In the result callback, push results to a completion queue and call `lws_cancel_service`
+- On the main thread, drain the completion queue and send EVENT + EOSE messages
+
+### Phase 3: Reduce Per-Row Overhead in REQ Results (Low-Medium Impact)
+
+Currently each row from a REQ query gets `cJSON_Parse` just to check NIP-40 expiration. This is wasteful:
+
+- Option A: Add an `expiration` column to the events table so expiration filtering can be done in SQL
+- Option B: Store expiration timestamp in a fast-parse format (extract during INSERT, store as integer column)
+- Option C: Use string search on the raw JSON for the expiration tag instead of full parse
+
+### Phase 4: Config Value Caching (Low Impact, Easy Win)
+
+`get_config_int` and `get_config_bool` are called on every message in hot paths. These do SQLite queries. Cache config values in memory with a TTL or invalidation signal, so the main loop only refreshes them periodically (already done for `debug_level` every 60s — extend to all hot-path config values).
+
+## Implementation Priority
+
+| Phase | Impact | Risk | Complexity |
+|-------|--------|------|------------|
+| Phase 1: Async EVENT | **High** - removes crypto from main thread | Medium - async state management | Medium-High |
+| Phase 2: Async REQ | **Medium** - unblocks main thread during queries | Low - infrastructure exists | Medium |
+| Phase 3: Expiration optimization | **Low-Medium** - reduces per-row parse cost | Low | Low |
+| Phase 4: Config caching | **Low** - reduces DB round-trips | Very Low | Low |
+
+## Detailed Design: Phase 1 (Async EVENT Processing)
+
+### New Components
+
+#### Completion Queue (`src/completion_queue.h/.c`)
+A thread-safe FIFO queue for posting results from worker threads back to the main thread:
+
+```c
+typedef struct {
+    int type;           // COMPLETION_TYPE_EVENT_RESULT, COMPLETION_TYPE_REQ_RESULT, etc.
+    void* data;         // Type-specific result data
+    struct lws* wsi;    // Target WebSocket connection
+    void* pss;          // Per-session data
+} completion_item_t;
+
+int completion_queue_init(void);
+int completion_queue_push(completion_item_t* item);
+completion_item_t* completion_queue_pop(void);  // Non-blocking
+void completion_queue_shutdown(void);
+```
+
+#### Event Worker Thread
+A dedicated pthread that processes EVENT validation/storage:
+
+```c
+typedef struct {
+    cJSON* event;           // Parsed event JSON - ownership transferred
+    cJSON* full_message;    // Full message JSON for context
+    struct lws* wsi;
+    void* pss;
+    char sub_id[64];        // For response routing
+} event_work_item_t;
+```
+
+#### Main Loop Integration
+Add a completion queue drain step to the main event loop. After `lws_service` returns (either from timeout or `lws_cancel_service` wake), check the completion queue:
+
+```c
+while (g_server_running && !g_shutdown_flag) {
+    int result = lws_service(ws_context, 1000);
+    
+    // NEW: Drain completion queue
+    completion_item_t* item;
+    while ((item = completion_queue_pop()) != NULL) {
+        process_completion(item);  // Send OK, broadcast, etc.
+        free(item);
+    }
+    
+    // ... existing periodic checks ...
+}
+```
+
+### Changes to Existing Code
+
+1. **`nostr_relay_callback` EVENT path**: After JSON parse and dedup check, instead of calling `nostr_validate_unified_request` + `store_event` + `broadcast_event_to_subscriptions` synchronously, submit an `event_work_item_t` to the event worker queue and return 0 immediately.
+
+2. **`store_event`**: No changes needed — it already uses `thread_pool_execute_store_event_sync` which will run on the DB writer thread. The event worker thread will call it.
+
+3. **`broadcast_event_to_subscriptions`**: No changes needed — it will be called from the main thread when processing the completion item, which is correct since it calls `queue_message_take_ownership` (requires lws thread).
+
+### Thread Safety Considerations
+
+- The `cJSON* event` object must be fully owned by the worker thread during processing. The main thread must not access it after submission.
+- The `wsi` and `pss` pointers could become invalid if the client disconnects while the event is being processed. The completion handler must validate that the connection is still alive before sending the OK response.
+- A generation counter or epoch on `pss` can detect stale references.
+
+## What Cannot Be Offloaded
+
+- **`lws_write` / `queue_message`**: Must happen on the lws service thread
+- **`lws_callback_on_writable`**: Must happen on the lws service thread  
+- **`lws_close_reason`**: Must happen on the lws service thread
+- **Subscription list iteration for broadcast**: Accesses `lws_wsi_user` which is lws-internal
+
+These are fundamental libwebsockets constraints. The pattern is always: do computation off-thread, post result to completion queue, wake main thread, do I/O on main thread.
+
+## Expected Impact
+
+With Phase 1 alone, the main thread would no longer perform:
+- ed25519 signature verification (~100-500μs per event depending on CPU)
+- Synchronous DB store wait (~50-200μs per event)
+- Event classification, tag serialization, JSON serialization for storage
+
+This should reduce main-thread CPU by roughly 30-50% for EVENT-heavy workloads, shifting that work to the event worker thread and DB threads.

+# C-Relay Memory Leak Investigation & Fix Plan
+
+## Problem Statement
+
+c-relay reached **1.56 GB** of its 1.5 GB `MemoryHigh` cgroup limit after only **1 hour 37 minutes** of runtime. The kernel is actively throttling the process with swap pressure (1.8M swap used). This strongly indicates one or more memory leaks causing unbounded growth.
+
+## Root Cause Analysis
+
+After thorough code review, I identified **three categories** of memory issues:
+
+1. **Confirmed `get_config_value()` leaks** — the most pervasive issue
+2. **Potential structural leaks** in subscription/connection lifecycle
+3. **Stack pressure** from large stack-allocated arrays
+
+---
+
+## Category 1: `get_config_value()` Leaks (HIGH SEVERITY — Most Likely Root Cause)
+
+### The Core Problem
+
+[`get_config_value()`](src/config.c:293) calls [`get_config_value_from_table()`](src/config.c:1690) which returns `strdup(value)` — a **heap-allocated string that the caller must free**. Many call sites treat the return value as a borrowed pointer and never free it.
+
+**Every unfree'd call leaks ~64-256 bytes per invocation.** On a busy relay processing hundreds of events/second, this accumulates to GB-scale leaks within hours.
+
+### Confirmed Leak Sites
+
+#### `websockets.c` — Called on EVERY incoming event
+
+| Line | Code | Frequency | Severity |
+|------|------|-----------|----------|
+| [1527](src/websockets.c:1527) | `get_config_value("relay_pubkey")` — auth bypass check for kind 14 DMs | Every kind-14 event | **HIGH** |
+| [1549](src/websockets.c:1549) | `get_config_value("admin_pubkey")` — auth bypass check for kind 23456 | Every kind-23456 event | **MEDIUM** |
+| [2704](src/websockets.c:2704) | `get_config_value("relay_pubkey")` — DM stats command processing | Every DM to relay | **MEDIUM** |
+| [2742](src/websockets.c:2742) | `get_config_value("admin_pubkey")` — DM admin check | Every DM to relay | **MEDIUM** |
+
+#### `main.c` — Called on EVERY admin event check
+
+| Line | Code | Frequency | Severity |
+|------|------|-----------|----------|
+| [1718](src/main.c:1718) | `get_config_value("relay_pubkey")` — inside a loop iterating tags | Every admin event, per tag | **CRITICAL** |
+| [1742](src/main.c:1742) | `get_config_value("admin_pubkey")` — admin authorization | Every admin event | **HIGH** |
+

+
+| Line | Code | Frequency | Severity |
+|------|------|-----------|----------|
+| [377](src/config.c:377) | `get_config_value("nip42_auth_required_kinds")` — NIP-42 kind check | Every incoming event | **CRITICAL** |
+
+#### `ip_ban.c` — Called on EVERY ban check
+
+| Line | Code | Frequency | Severity |
+|------|------|-----------|----------|
+| [255](src/ip_ban.c:255) | `get_config_value("idle_ban_whitelist")` — whitelist check | Every connection check | **HIGH** |
+
+#### `nip042.c` — Called on every auth verification
+
+| Line | Code | Frequency | Severity |
+|------|------|-----------|----------|
+| [99](src/nip042.c:99) | `get_config_value("relay_url")` — relay URL for auth verification | Every NIP-42 auth | **MEDIUM** |
+
+#### `request_validator.c` — Called on every auth rules check
+
+| Line | Code | Frequency | Severity |
+|------|------|-----------|----------|
+| [208](src/request_validator.c:208) | `get_config_value("auth_enabled")` — properly freed | N/A | OK |
+| [216](src/request_validator.c:216) | `get_config_value("auth_rules_enabled")` — properly freed | N/A | OK |
+| [304](src/request_validator.c:304) | `get_config_value("admin_pubkey")` — NOT freed | Every event validation | **HIGH** |
+| [320](src/request_validator.c:320) | `get_config_value("nip42_auth_enabled")` — NOT freed | Every event validation | **HIGH** |
+
+### Files That DO Free Correctly (for reference)
+
+- [`nip011.c`](src/nip011.c:127) — Properly frees all `get_config_value()` results
+- [`nip013.c`](src/nip013.c:43) — Properly frees `pow_mode`
+- [`request_validator.c`](src/request_validator.c:191) — Properly frees `nip42_timeout` and `nip42_tolerance`
+
+### Estimated Impact
+
+On a relay processing ~100 events/second:
+- `is_nip42_auth_required_for_kind()` leaks ~100-200 bytes × 100/sec = **~10-20 KB/sec**
+- `ip_is_whitelisted()` leaks ~100 bytes × connections/sec
+- `is_authorized_admin_event()` leaks inside tag loop — potentially **multiple leaks per event**
+- Combined: **~50-100 KB/sec → ~180-360 MB/hour** — consistent with the observed 1.56 GB in 97 minutes
+
+---
+
+## Category 2: Structural Lifecycle Leaks (MEDIUM SEVERITY)
+
+### 2a. `LWS_CALLBACK_CLOSED` — Inactive Subscription Skip
+
+In [`websockets.c:2339`](src/websockets.c:2339), the cleanup handler only collects subscription IDs where `sub->active` is true:
+
+```c
+if (sub->active) {  // Only process active subscriptions
+    temp_sub_id_t* temp = malloc(sizeof(temp_sub_id_t));
+```
+
+If a subscription was marked inactive by another thread between the time it was added and the connection close, it will be **skipped** — never removed from the global manager, never freed. The subscription object, its filters, and all cJSON objects within leak permanently.
+
+### 2b. `connection_list_remove` Potential
+
+The `connection_list_remove(wsi)` call at [`websockets.c:2252`](src/websockets.c:2252) happens before pss cleanup. Need to verify the connection list implementation doesn't hold references that prevent cleanup.
+
+### 2c. `ip_connection_info_t` Leak on Disconnect
+
+The per-IP connection tracking in [`subscriptions.h:79`](src/subscriptions.h:79) creates `ip_connection_info_t` nodes via `calloc`. These are only removed by `remove_ip_connection()` — need to verify this is called on every disconnect path.
+
+---
+
+## Category 3: Stack Pressure (LOW SEVERITY but notable)
+
+### 3a. `candidates_to_check` Stack Array
+
+In [`subscriptions.c:810`](src/subscriptions.c:810):
+
+```c
+subscription_t* candidates_to_check[MAX_TOTAL_SUBSCRIPTIONS]; // 5000 × 8 bytes = 40 KB
+```
+
+This allocates **40 KB on the stack** for every `broadcast_event_to_subscriptions()` call. While not a heap leak, it contributes to high memory pressure under concurrent load.
+
+### 3b. `added_kinds` Bitmap
+
+In [`subscriptions.c:68`](src/subscriptions.c:68):
+
+```c
+unsigned char added_kinds[8192] = {0};  // 8 KB on stack
+```
+
+---
+
+## Fix Implementation Plan
+
+### Phase 1: Fix `get_config_value()` Leaks (Highest Impact)
+
+**Strategy A — Preferred: Add a config cache layer**
+
+Instead of fixing 20+ call sites, add a **cached config system** that reads values once and caches them in memory, invalidating on config change events. This eliminates both the leak AND the repeated SQLite queries per event.
+
+```
+Config Cache Architecture:
+- Static hash table of key-value pairs
+- Populated at startup and on config change events
+- get_config_value_cached() returns const pointer to cached value (no allocation)
+- Existing get_config_value() kept for dynamic/rare lookups
+```
+
+**Strategy B — Quick fix: Free at every call site**
+
+Add `free((char*)result)` after every `get_config_value()` call that doesn't already free. This is more error-prone but faster to implement.
+
+**Recommendation: Implement Strategy A for hot-path values (relay_pubkey, admin_pubkey, auth settings), Strategy B for cold-path values.**
+
+### Phase 2: Fix Structural Leaks
+
+1. **Fix inactive subscription skip in CLOSED handler** — Remove the `if (sub->active)` guard, or add a second pass that also collects inactive subscriptions for cleanup
+2. **Verify `remove_ip_connection()` is called on all disconnect paths**
+3. **Add defensive cleanup** — periodic sweep of orphaned subscriptions
+
+### Phase 3: Add Memory Monitoring
+
+1. **Add a `/stats` endpoint** that reports:
+   - Current RSS/VSZ from `/proc/self/status`
+   - Active subscription count
+   - Message queue depth across all sessions
+   - Config cache hit/miss ratio
+2. **Add periodic memory logging** to the service loop
+3. **Consider integrating jemalloc** for better allocation tracking in production
+
+### Phase 4: Reduce Stack Pressure
+
+1. Move `candidates_to_check` to heap allocation with `malloc`/`free`
+2. Consider reducing `MAX_TOTAL_SUBSCRIPTIONS` or using a dynamic array
+
+---
+
+## Verification Strategy
+
+1. **Build with AddressSanitizer** (`-fsanitize=address`) for development testing
+2. **Run under Valgrind** with `--leak-check=full` for comprehensive leak detection
+3. **Monitor RSS over time** after fixes — should plateau rather than grow linearly
+4. **Load test** with `tests/load_tests.sh` while monitoring memory
+
+---
+
+## Immediate Mitigation
+
+While fixes are being implemented:
+1. **Raise `MemoryHigh`** to 2 GB in the systemd unit to prevent throttling
+2. **Add a cron job** to restart the service every 12-24 hours
+3. **Monitor with**: `watch -n 5 'cat /proc/$(pgrep c_relay)/status | grep -E "VmRSS|VmSwap"'`
+
+---

+# PostgreSQL Nostr Relay Architecture Analysis
+
+This document summarizes common approaches and best practices for building Nostr relays backed by PostgreSQL, based on industry-standard designs and existing open-source relay implementations.
+
+## Identified Projects
+*   **Nostrss**: High-performance Rust-based relay.
+*   **Nostrgres**: Focused on PostgreSQL integration with complex event filtering.
+*   **Relay-rs (Postgres branch)**: General purpose high-throughput relay.
+*   **Nostream** ([github.com/Cameri/nostream](https://github.com/Cameri/nostream)): Production-ready TypeScript relay backed by PostgreSQL and Redis.
+*   **Nostr-Relay-NestJS** ([github.com/CodyTseng/nostr-relay-nestjs](https://github.com/CodyTseng/nostr-relay-nestjs)): High-performance relay built with NestJS and PostgreSQL, utilizing Kysely for type-safe database interactions.
+
+## Detailed Analysis
+
+### 1. Common Schema Patterns
+*   **Event Storage (JSONB)**: Most PostgreSQL-backed relays store the raw event as a JSONB object in a central `events` table. This provides flexibility for the evolving Nostr spec while allowing efficient extraction of fields.
+*   **Tag Denormalization**: While the raw event is in JSONB, performant relays extract tags (like `p`, `e`, `t`, `d`) into a separate `tags` table with foreign key relationships to the `events` table. This avoids slow JSONB traversal during complex filter queries.
+*   **Author/Publisher Tracking**: A dedicated `authors` or `pubkeys` table is typically used to maintain indexing on the `pubkey` field, enabling quick lookups of user activity.
+
+### 2. Performance Optimization
+*   **GIN Indexes on JSONB**: Crucial for filtering on specific event tags or custom properties stored within the event object. GIN indexes with `jsonb_path_ops` are generally preferred for equality checks.
+*   **Time-Series Partitioning**: Given the append-only nature of Nostr, partitioning the `events` table by time (e.g., daily or weekly chunks) is highly recommended. This significantly improves query performance for recent data and simplifies data expiration/deletion.
+*   **Clustering**: Clustering the `events` table by the timestamp index can reduce disk I/O, as it keeps temporally related events physically adjacent on the disk.
+
+### 3. Schema Management Approaches
+*   **Migrations**: Most mature relays utilize migration tools (like `Flyway`, `Diesel migrations`, or `Golang-migrate`) to version control database schema changes. This is critical for production stability.
+*   **Auto-generation**: Some lightweight prototypes auto-generate schemas at startup. This is generally discouraged for production due to the risk of destructive changes, data loss, or blocking DDL operations on large tables.
+
+## Recommendations for Building a New Relay
+1.  **Prioritize Denormalization**: Do not rely solely on JSONB queries for high-traffic filters. Extract indexed tags into dedicated columns or tables.
+2.  **Use Partitioning from Day One**: Implementing native PostgreSQL partitioning (e.g., using `pg_partman`) is much easier before the dataset grows to millions of rows.
+3.  **Connection Pooling**: PostgreSQL requires aggressive connection management. Use a high-performance pooler like `PgBouncer` to handle the large number of concurrent, short-lived connections common in WebSocket-based relay traffic.
+4.  **Asynchronous Writes**: Decouple the WebSocket ingestion thread from the database writer thread to ensure that slow database writes do not impact the relay's responsiveness.
+
+## Nostream ([github.com/Cameri/nostream](https://github.com/Cameri/nostream))
+
+A production-ready Nostr relay written in TypeScript (Node.js), backed by PostgreSQL 14+ and Redis. Uses Knex.js for versioned migrations.
+
+### PostgreSQL Schema
+
+The schema is fully normalized — no JSONB blob for the whole event. Tags are stored separately and populated by a trigger.
+
+**`events` table** — one row per event, tags kept as a JSONB column for the trigger to process:
+```sql
+CREATE TABLE events (
+    id               UUID     PRIMARY KEY DEFAULT uuid_generate_v4(),
+    event_id         BYTEA    UNIQUE NOT NULL,  -- 32-byte hash
+    event_pubkey     BYTEA    NOT NULL,
+    event_kind       INTEGER  UNSIGNED NOT NULL,
+    event_created_at INTEGER  UNSIGNED NOT NULL,
+    event_content    TEXT     NOT NULL,
+    event_tags       JSONB,                     -- raw tags array, source of truth for trigger
+    event_signature  BYTEA    NOT NULL,
+    remote_address   TEXT,
+    expires_at       INTEGER,
+    deleted_at       TIMESTAMP,
+    event_deduplication JSONB,                 -- used for replaceable event conflict key
+    first_seen       TIMESTAMP DEFAULT now()
+);
+
+-- Indexes
+CREATE INDEX ON events (event_pubkey);
+CREATE INDEX ON events (event_kind);
+CREATE INDEX ON events (event_created_at);
+CREATE INDEX ON events (expires_at);
+CREATE INDEX event_tags_idx ON events USING GIN (event_tags);  -- GIN on raw JSONB
+
+-- Unique index enforcing NIP-16 replaceable event semantics
+CREATE UNIQUE INDEX replaceable_events_idx ON events (event_pubkey, event_kind)
+    WHERE event_kind = 0 OR event_kind = 3
+       OR (event_kind >= 10000 AND event_kind < 20000);
+```
+
+**`event_tags` table** — denormalized single-letter tags, populated by a PostgreSQL trigger on `events`:
+```sql
+CREATE TABLE event_tags (
+    id         UUID  PRIMARY KEY DEFAULT uuid_generate_v4(),
+    event_id   BYTEA NOT NULL,
+    tag_name   TEXT  NOT NULL,   -- single-letter only (e.g. 'e', 'p', 't')
+    tag_value  TEXT  NOT NULL
+);
+
+CREATE INDEX ON event_tags (event_id);
+CREATE INDEX ON event_tags (tag_name, tag_value);
+
+-- Trigger: on INSERT/UPDATE/DELETE to events, repopulate event_tags
+CREATE OR REPLACE FUNCTION process_event_tags() RETURNS TRIGGER AS $$
+DECLARE
+  tag_element jsonb;
+BEGIN
+  DELETE FROM event_tags WHERE event_id = OLD.event_id;
+  IF TG_OP = 'INSERT' OR TG_OP = 'UPDATE' THEN
+    FOR tag_element IN SELECT jsonb_array_elements(NEW.event_tags) LOOP
+      IF length(trim('"' FROM (tag_element->0)::text)) = 1
+         AND (tag_element->1)::text IS NOT NULL THEN
+        INSERT INTO event_tags (event_id, tag_name, tag_value)
+        VALUES (NEW.event_id,
+                trim('"' FROM (tag_element->0)::text),
+                trim('"' FROM (tag_element->1)::text));
+      END IF;
+    END LOOP;
+  END IF;
+  RETURN NEW;
+END;
+$$ LANGUAGE plpgsql;
+
+CREATE TRIGGER insert_event_tags
+AFTER INSERT OR UPDATE OR DELETE ON events
+FOR EACH ROW EXECUTE FUNCTION process_event_tags();
+```
+
+Tag queries (`#e`, `#p`, etc.) join `event_tags` rather than traversing the JSONB array.
+
+**`users` and `invoices` tables** — for paid relay admission (Lightning payments):
+```sql
+CREATE TABLE users (
+    pubkey          BYTEA    PRIMARY KEY,
+    is_admitted     BOOLEAN  DEFAULT FALSE,
+    balance         BIGINT   DEFAULT 0,      -- in msats
+    tos_accepted_at DATETIME
+);
+
+CREATE TABLE invoices (
+    id               UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
+    pubkey           BYTEA NOT NULL,
+    bolt11           TEXT  NOT NULL,
+    amount_requested BIGINT UNSIGNED NOT NULL,
+    amount_paid      BIGINT UNSIGNED,
+    unit             ENUM('msats','sats','btc'),
+    status           ENUM('pending','completed','expired'),
+    description      TEXT,
+    confirmed_at     DATETIME,
+    expires_at       DATETIME
+);
+```
+
+### How Redis Is Used
+
+Redis is **not** used for subscription fan-out. Subscription delivery is handled entirely in-process: each `WebSocketAdapter` holds a `Map<subscriptionId, filters[]>`, and a broadcast event walks all connected clients and filters locally.
+
+Redis has two actual roles:
+
+1. **Sliding-window rate limiting** — The `SlidingWindowRateLimiter` uses Redis sorted sets to track request timestamps per key (pubkey, IP, etc.) within a rolling time window:
+   - `ZREMRANGEBYSCORE key 0 (now - period)` — evict old entries
+   - `ZADD key timestamp member` — record this hit
+   - `ZRANGE key 0 -1` — count hits in window
+   - `EXPIRE key period` — auto-cleanup
+   - Keys follow the pattern `<pubkey>:events:<period>` or `<ip>:message:<period>`
+
+2. **General-purpose cache** — A `RedisAdapter` wraps the client with `get`/`set`/`hasKey` helpers, used for caching admission checks (e.g. `<pubkey>:is-admitted`). The event handler has a `TODO` comment noting that the `userRepository.findByPubkey()` call should be replaced with a cache lookup — meaning this is partially implemented.

+
+---
+
+## Critical Performance Issues
+
+### 1. **SLOWEST QUERY: 672ms Tag Search (IP: 192.42.116.178)**
+
+```sql
+SELECT id, pubkey, created_at, kind, content, sig, tags 
+FROM events 
+WHERE 1=1 
+  AND (kind < 20000 OR kind >= 30000) 
+  AND kind IN (5,6300,7000,2004,1622) 
+  AND EXISTS (
+    SELECT 1 FROM json_each(json(tags)) 
+    WHERE json_extract(value, '$[0]') = ? 
+      AND json_extract(value, '$[1]') IN (?)
+  ) 
+ORDER BY created_at DESC 
+LIMIT 100
+```
+
+**Problem:** Full table scan with JSON parsing for every row  
+**Impact:** 672ms for 0 results (wasted computation)  
+**Root Cause:** No index on tag values, requires scanning all events
+
+---
+
+### 2. **Monitoring System Queries: 540-550ms Each**
+
+```sql
+SELECT * FROM active_subscriptions_log 
+ORDER BY created_at DESC
+```
+
+**Occurrences:** 4 queries in 6 minutes  
+**Average Time:** 545ms  
+**Rows Returned:** 20-52 rows  
+**Problem:** Extremely slow for small result sets  
+**Root Cause:** Likely missing index on `created_at` column
+
+---
+
+### 3. **Tag-Based Searches (json_each) - 53% of All Queries**
+
+- **Total:** 194 queries (53% of all queries)
+- **Pattern:** `EXISTS (SELECT 1 FROM json_each(json(tags)) WHERE ...)`
+- **Most Common:** Kind 1984 (105 queries), Kind 1111 (47 queries)
+- **Problem:** Every tag search requires full JSON parsing
+
+**Example Pattern:**
+```sql
+WHERE kind IN (1984) 
+  AND pubkey IN (?) 
+  AND EXISTS (
+    SELECT 1 FROM json_each(json(tags)) 
+    WHERE json_extract(value, '$[0]') = ? 
+      AND json_extract(value, '$[1]') IN (?,?,?,?,?,?,?,?,?,?,?)
+  )
+```
+
+---
+
+### 4. **Multiple Pubkey Lookups (Kind 10002)**
+
+- **Total:** 64 queries for kind 10002
+- **Average Time:** 2,500-3,300 μs (2.5-3.3ms)
+- **Pattern:** Queries with 15-50 pubkeys in `IN` clause
+- **Problem:** Large `IN` clauses without proper indexing
+
+**Example:**
+```sql
+WHERE kind IN (10002) 
+  AND pubkey IN (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)

+
+## Optimization Recommendations
+
+### Priority 1: Critical (Immediate Action Required)
+
+#### 1.1 Add Index on `active_subscriptions_log.created_at`
+**Impact:** Will reduce monitoring queries from 540ms to <10ms  
+**Effort:** Low  
+**SQL:**
+```sql
+CREATE INDEX IF NOT EXISTS idx_active_subscriptions_created_at 
+ON active_subscriptions_log(created_at DESC);
+```
+
+#### 1.2 Implement Tag Indexing System
+**Impact:** Will reduce tag searches from 100-600ms to <10ms  
+**Effort:** High  
+**Options:**
+- **Option A:** Create separate `event_tags` table with indexes
+  ```sql
+  CREATE TABLE event_tags (
+    event_id TEXT NOT NULL,
+    tag_name TEXT NOT NULL,
+    tag_value TEXT NOT NULL,
+    FOREIGN KEY (event_id) REFERENCES events(id)
+  );
+  CREATE INDEX idx_event_tags_lookup ON event_tags(tag_name, tag_value);
+  ```
+- **Option B:** Use SQLite JSON1 extension with generated columns (if available)
+- **Option C:** Implement application-level tag caching
+
+**Recommended:** Option A (most reliable and performant)
+
+---
+
+### Priority 2: High (Implement Within Week)
+
+#### 2.1 Optimize Multiple Pubkey Queries
+**Current:** `pubkey IN (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)`  
+**Problem:** Large IN clauses are inefficient  
+**Solution:** 
+- Add composite index: `CREATE INDEX idx_events_kind_pubkey ON events(kind, pubkey, created_at DESC);`
+- Consider query rewriting for >10 pubkeys
+
+#### 2.2 Add Query Result Caching
+**Target Queries:**
+- Kind 0 (profile) lookups - frequently repeated
+- Kind 10002 (relay lists) - relatively static
+- Kind 1984 (reports) - can be cached for 30-60 seconds
+
+**Implementation:**
+- Use in-memory LRU cache (e.g., 1000 entries)
+- Cache key: hash of SQL + parameters
+- TTL: 30-60 seconds for most queries
+
+---
+
+### Priority 3: Medium (Optimize Over Time)
+
+#### 3.1 Disable or Throttle Monitoring Queries
+**Current:** Monitoring queries run every ~60 seconds  
+**Impact:** Each query takes 540ms  
+**Options:**
+- Increase throttle to 300 seconds (5 minutes)
+- Disable monitoring entirely if not actively used
+- Optimize `active_subscriptions_log` table structure
+
+#### 3.2 Implement Query Complexity Limits
+**Problem:** Some queries scan entire table (e.g., 672ms query returned 0 results)  
+**Solution:**
+- Reject queries without time bounds (require `since` or `until`)
+- Limit number of kinds in single query (max 10)
+- Limit number of pubkeys in single query (max 20)
+
+#### 3.3 Add Composite Indexes for Common Patterns
+```sql
+-- For kind + created_at queries (most common pattern)
+CREATE INDEX idx_events_kind_created ON events(kind, created_at DESC);
+
+-- For kind + pubkey + created_at queries
+CREATE INDEX idx_events_kind_pubkey_created ON events(kind, pubkey, created_at DESC);
+```
+
+---
+
+## Database Schema Recommendations
+
+### Current Issues
+1. **No tag indexing** - Forces full table scans with JSON parsing
+2. **Missing created_at indexes** - Monitoring queries are extremely slow
+3. **No composite indexes** - Multi-condition queries inefficient
+
+### Recommended Schema Changes
+
+```sql
+-- 1. Add tag indexing table
+CREATE TABLE IF NOT EXISTS event_tags (
+    event_id TEXT NOT NULL,
+    tag_name TEXT NOT NULL,
+    tag_value TEXT NOT NULL,
+    FOREIGN KEY (event_id) REFERENCES events(id) ON DELETE CASCADE
+);
+
+CREATE INDEX idx_event_tags_lookup ON event_tags(tag_name, tag_value);
+CREATE INDEX idx_event_tags_event_id ON event_tags(event_id);
+
+-- 2. Add monitoring table index
+CREATE INDEX IF NOT EXISTS idx_active_subscriptions_created_at 
+ON active_subscriptions_log(created_at DESC);
+
+-- 3. Add composite indexes for common query patterns
+CREATE INDEX IF NOT EXISTS idx_events_kind_created 
+ON events(kind, created_at DESC);
+
+CREATE INDEX IF NOT EXISTS idx_events_kind_pubkey_created 
+ON events(kind, pubkey, created_at DESC);
+
+-- 4. Add index for pubkey lookups
+CREATE INDEX IF NOT EXISTS idx_events_pubkey_created 
+ON events(pubkey, created_at DESC);
+```
+
+---
+
+## Expected Performance Improvements
+
+| Optimization | Current Avg | Expected Avg | Improvement |
+|--------------|-------------|--------------|-------------|
+| Tag searches (with event_tags table) | 100-600ms | 5-20ms | **95-97%** |
+| Monitoring queries (with index) | 540ms | 5-10ms | **98%** |
+| Multiple pubkey queries (with index) | 2.5-3.3ms | 0.5-1ms | **70-80%** |
+| Overall average query time | 10.4ms | 2-3ms | **70-80%** |
+
+---
+
+## Client Behavior Analysis
+
+### Potentially Abusive Patterns
+
+#### IP: 192.42.116.178 (51 queries)
+- **Issue:** Generated the slowest query (672ms)
+- **Pattern:** Complex tag searches with multiple kinds
+- **Recommendation:** Monitor for repeated expensive queries
+
+#### IP: 45.84.107.222 (101 queries - 27.6% of total)
+- **Issue:** Highest query volume
+- **Pattern:** Mix of kind 10002, 1984, and various other kinds
+- **Recommendation:** Acceptable if queries are efficient; monitor for abuse
+
+### Normal Behavior
+- Most queries are <1ms (fast)
+- Majority return 0-10 rows (reasonable)
+- Query patterns match typical Nostr client behavior
+
+---
+
+## Action Plan
+
+### Immediate (Today)
+1. ✅ Add index on `active_subscriptions_log.created_at`
+2. ✅ Increase monitoring throttle from 60s to 300s (or disable)
+3. ✅ Monitor IP 192.42.116.178 for repeated expensive queries
+
+### This Week
+1. ⏳ Design and implement `event_tags` table
+2. ⏳ Add composite indexes for common query patterns
+3. ⏳ Implement query complexity limits (require time bounds)
+
+### This Month
+1. ⏳ Implement query result caching (LRU cache)
+2. ⏳ Add query cost estimation and rejection
+3. ⏳ Optimize subscription matching algorithm
+
+---
+
+## Monitoring Recommendations
+
+### Key Metrics to Track
+1. **Average query time** - Target: <5ms
+2. **P95 query time** - Target: <50ms
+3. **P99 query time** - Target: <100ms
+4. **Queries >100ms** - Target: <1% of queries
+5. **Tag search percentage** - Target: <30% after optimization
+
+### Alert Thresholds
+- **Critical:** Average query time >20ms for 5 minutes
+- **Warning:** Any single query >1000ms (1 second)
+- **Info:** Client making >100 queries/minute
+
+---
+
+## Conclusion
+
+The relay is experiencing performance issues primarily due to:
+1. **Lack of tag indexing** (53% of queries affected)
+2. **Missing indexes on monitoring tables** (540ms queries)
+3. **Inefficient multiple pubkey lookups**
+
+Implementing the recommended optimizations will reduce average query time from **10.4ms to 2-3ms** (70-80% improvement) and eliminate the 500-600ms slow queries entirely.
+
+**Priority:** Implement tag indexing system and add missing indexes within 1 week to prevent performance degradation as database grows.

+# Remaining Implementation Plan — Zero SQLite on Main Thread + PG Fork Readiness
+
+## Overview
+
+This plan covers all remaining work to achieve two goals:
+1. **Zero direct SQLite calls on lws-main** during the event loop
+2. **Clean `db_ops` abstraction boundary** so the PG fork has no raw `sqlite3_*` calls outside `db_ops.c`
+
+## Current State
+
+### Completed (Fixes 1-5, 7 + Phases 1-3, 5)
+- Global config cache with 5s TTL
+- Dedup check moved to event worker
+- Async COUNT queries via thread pool
+- WoT auth rules cached per-session
+- Special-kind EVENT store through async worker
+- Subscription logging via fire-and-forget write queue
+- IP ban periodic save via write queue
+- g_db nulled before event loop
+
+### Remaining
+- Fix 6: Reduce reader threads (trivial)
+- Fix 8: Move periodic tasks off main thread (partial — IP ban save done, monitoring/status not)
+- Fix 9: Cache NIP-11 response
+- Sync `store_event()` calls from admin/DM/NIP-09 paths
+- Raw `sqlite3_*` calls in `thread_pool.c` and `websockets.c`
+- COUNT query path in `websockets.c` still uses `json_each()` instead of `event_tags`
+
+---
+
+## Phase A: Move Remaining Periodic Tasks Off Main Thread
+
+**Goal:** Eliminate the last regular SQLite calls from the lws-main event loop timer.
+
+### A1: Move `generate_and_post_status_event()` to write worker
+
+Currently called synchronously from the main event loop at `websockets.c:3455`.
+
+**Changes:**
+- Add `THREAD_POOL_JOB_STATUS_POST` to `thread_pool.h` job type enum
+- Add executor in `thread_pool.c` that calls `generate_and_post_status_event()`
+- In `websockets.c` main loop, replace direct call with `thread_pool_submit_write()` job
+- The write worker has a DB connection, so `generate_stats_json()` → `store_event()` → `broadcast_event_to_subscriptions()` all work naturally
+- Note: `broadcast_event_to_subscriptions()` is thread-safe (uses its own mutex)
+
+**Files:** `thread_pool.h`, `thread_pool.c`, `websockets.c`
+
+### A2: Move monitoring queries to read/write worker
+
+`monitoring_on_event_stored()` and `monitoring_on_subscription_change()` in `api.c` call `generate_event_driven_monitoring()` / `generate_subscription_driven_monitoring()` which do DB queries and then broadcast ephemeral events.
+
+**Changes:**
+- Add `THREAD_POOL_JOB_MONITORING` job type
+- Submit monitoring generation as a read job (it mostly does SELECTs)
+- The completion broadcasts the ephemeral event via `lws_cancel_service()` + completion queue
+- Alternative simpler approach: since these are throttled (default 5s) and only fire when kind 24567 subscribers exist, they could run on the write worker as fire-and-forget
+
+**Files:** `thread_pool.h`, `thread_pool.c`, `api.c`, `websockets.c`
+
+### A3: Move `ip_ban_cleanup()` and `ip_ban_log_stats()` to write worker
+
+Currently called from the 60-second periodic timer at `websockets.c:3479-3480`.
+
+**Changes:**
+- Add `THREAD_POOL_JOB_IP_BAN_CLEANUP` job type (or reuse a generic callback job)
+- Submit as fire-and-forget write job from the periodic timer
+- `ip_ban_cleanup()` does in-memory cleanup + optional DB writes
+- `ip_ban_log_stats()` is purely logging, no DB
+
+**Files:** `thread_pool.h`, `thread_pool.c`, `ip_ban.c`, `websockets.c`
+
+---
+
+## Phase B: Route Remaining Sync `store_event()` Calls Through Async Worker
+
+**Goal:** Eliminate all synchronous `store_event()` calls from lws-main context.
+
+### Current sync `store_event()` call sites on main thread
+
+| Call site | File | Context | Frequency |
+|-----------|------|---------|-----------|
+| Kind 1059 gift wrap store | `websockets.c:1795,1803,1819` | NIP-17 DM processing | Low |
+| Kind 14 DM store | `websockets.c:1843` | NIP-17 DM processing | Low |
+| Regular event fallback | `websockets.c:1862,1876` | Non-async-eligible events | Low |
+| Kind 1059 (auth path) | `websockets.c:2594,2602,2618` | NIP-42 auth + DM | Low |
+| Kind 14 (auth path) | `websockets.c:2642` | NIP-42 auth + DM | Low |
+| Regular (auth path) | `websockets.c:2661,2675` | NIP-42 auth fallback | Low |
+| Admin response store | `config.c:2585` | Admin API response | Very low |
+| DM admin gift wrap | `dm_admin.c:389` | Admin DM response | Very low |
+| NIP-09 deletion store | `nip009.c:135` | Deletion events | Low |
+| Status event store | `api.c:595` | Periodic status post | Very low (handled by Phase A1) |
+| Admin response event | `api.c:908` | Admin API | Very low |
+| DM chat response | `api.c:1377` | Admin DM chat | Very low |
+| Relay-generated event | `api.c:2350` | Relay metadata | Very low |
+| DM stats response | `websockets.c:3648` | DM stats command | Very low |
+
+### Strategy
+
+Rather than converting each call site individually, create a **synchronous-to-async bridge**:
+
+**Changes:**
+- Create `store_event_async(cJSON* event, store_event_callback_t cb, void* ctx)` that submits the event to the write worker
+- For call sites that need the result (e.g., to broadcast after store), use a completion callback
+- For fire-and-forget sites (admin responses, DM responses), use NULL callback
+- The existing `store_event()` wrapper becomes: submit to write worker + block on completion (for backward compat during transition)
+- Eventually, all callers migrate to the async version
+
+**Alternative simpler approach:** Since these are all low-frequency paths, and the write worker already has a DB connection, we can submit them as generic write jobs with a callback that does the store + broadcast. The main thread just needs to hand off the event JSON.
+
+**Files:** `main.c`, `websockets.c`, `api.c`, `config.c`, `dm_admin.c`, `nip009.c`, `thread_pool.h`, `thread_pool.c`
+
+---
+
+## Phase C: `db_ops` Abstraction Cleanup for PG Fork
+
+**Goal:** Ensure all raw `sqlite3_*` calls are inside `db_ops.c` only. External code uses only `db_ops.h` functions.
+
+### C1: Add `db_open_worker_connection()` / `db_close_worker_connection()` to `db_ops.h`
+
+Currently, `thread_pool.c:208` and `websockets.c:537` call `sqlite3_open_v2()` directly.
+
+**Changes:**
+- Add to `db_ops.h`:
+  ```c
+  void* db_open_worker_connection(void);    // Returns opaque connection handle
+  void db_close_worker_connection(void* conn);
+  ```
+- Implementation in `db_ops.c`: opens a new SQLite connection with WAL + busy timeout
+- `thread_pool.c` worker init calls `db_open_worker_connection()` instead of raw `sqlite3_open_v2()`
+- `websockets.c` event-worker calls `db_open_worker_connection()` instead of raw `sqlite3_open_v2()`
+- Remove `#include <sqlite3.h>` from `thread_pool.c` and `websockets.c`
+
+**Files:** `db_ops.h`, `db_ops.c`, `thread_pool.c`, `websockets.c`
+
+### C2: Audit and remove remaining `sqlite3` includes outside `db_ops.c`
+
+After C1, grep for any remaining `sqlite3` references outside `db_ops.c` and eliminate them.
+
+**Files:** All `.c` files
+
+### C3: Unify COUNT query tag path
+
+The COUNT query builder in `websockets.c:3849` still uses `json_each(json(tags))` while the REQ query builder in `main.c:1604` uses the indexed `event_tags` table. Unify to use `event_tags` for consistency.
+
+**Files:** `websockets.c`
+
+---
+
+## Phase D: Quick Wins
+
+### D1: Fix 6 — Reduce reader threads from 4 to 1
+
+Change default in `thread_pool_init()` or make configurable. With all reads going through the pool, a single reader is sufficient unless profiling shows otherwise.
+
+**Files:** `thread_pool.c` or config default
+
+### D2: Fix 9 — Cache NIP-11 response
+
+Cache the serialized NIP-11 JSON string with a 60-second TTL. Invalidate on admin config change.
+
+**Files:** `nip011.c`
+
+---
+
+## Implementation Order
+
+| # | Task | Risk | Dependencies |
+|---|------|------|-------------|
+| 1 | A3: ip_ban_cleanup to write worker | Very Low | None |
+| 2 | A1: status post to write worker | Low | None |
+| 3 | A2: monitoring to worker | Low | None |
+| 4 | D1: reduce reader threads to 1 | Very Low | None |
+| 5 | D2: cache NIP-11 response | Very Low | None |
+| 6 | C1: db_open/close_worker_connection | Low | None |
+| 7 | C3: unify COUNT tag query path | Low | None |
+| 8 | C2: audit/remove sqlite3 includes | Very Low | C1 |
+| 9 | B: route sync store_event through async | Medium | A1 (status post already handled) |
+
+## Expected Outcome
+
+After all phases:
+- **lws-main has zero SQLite calls** during the event loop
+- **All `sqlite3_*` calls are inside `db_ops.c`** — clean abstraction boundary
+- **PG fork can replace `db_ops.c`** without touching any other file
+- Thread model is fully realized:
+  - `lws-main` = WebSocket I/O + JSON parse + subscription match + completion drain
+  - `event-worker` = signature verify + dedup + store submission
+  - `db-read` = REQ queries + COUNT queries + monitoring reads
+  - `db-write` = event INSERTs + subscription logging + periodic tasks + admin writes

+# Plan: Remove All SQLite from lws-main Thread
+
+## Problem Statement
+
+After implementing the 4 offload fixes (v2.1.4), `lws-main` still consumes **53.87% avg CPU** (down from 68.71%). Perf profiling shows **100% of the top symbols are SQLite** — B-tree traversal, page cache, VFS reads. The worker threads (`db-read`, `db-write`, `event-worker`) are nearly idle at 0.0–0.1%.
+
+The goal is to eliminate all synchronous SQLite access from `lws-main` so it only does: JSON parsing, WebSocket I/O, subscription matching (in-memory), and message queuing.
+
+## Thread Architecture Change
+
+Reduce from 7 threads to 4:
+
+```
+Current:  lws-main, db-read-1, db-read-2, db-read-3, db-read-4, db-write, event-worker
+Proposed: lws-main, db-read, db-write, event-worker
+```
+
+The 4 reader threads are overkill — they average 0.07–0.10% CPU each. A single `db-read` thread is sufficient for the current workload. This can be made configurable later if needed.
+
+## Remaining SQLite Calls on lws-main
+
+Every synchronous SQLite call that currently runs on `lws-main`:
+
+### Hot Path — Per-Event (every incoming EVENT message)
+
+| Call | Location | Frequency | Cost |

+
+### Per-EVENT — Validator Path (called from event-worker AND sync path)
+
+| Call | Location | Frequency | Cost |
+|------|----------|-----------|------|
+| `get_config_value("admin_pubkey")` | request_validator.c:308 | Every kind-23456 EVENT | SQLite SELECT |

+| `db_count_active_whitelist_rules()` | request_validator.c:536 | Every 5s (cached) | Opens separate SQLite connection |
+
+**Note:** These run on the **event-worker** thread for async-eligible events, but on **lws-main** for special kinds (14, 1059, 23456) that go through the sync validation path. They also run on lws-main for the `nostr_validate_unified_request()` call in the sync fallback.

+
+## Implementation Plan
+
+### Fix 1: Create Global Config Cache — Eliminate ALL get_config_* SQLite Calls
+
+**Impact: Very High** — eliminates 50+ distinct `get_config_value/int/bool` call sites across 8 source files
+
+The audit found `get_config_value/int/bool` calls in: `websockets.c`, `main.c`, `subscriptions.c`, `request_validator.c`, `nip011.c`, `nip013.c`, `nip040.c`, `nip042.c`, `ip_ban.c`, `dm_admin.c`, `api.c`, `config.c`. Every single one does a `SELECT value FROM config WHERE key=?` SQLite query.
+
+**Approach:** Replace `get_config_value_from_table()` with an in-memory hash map that is loaded once at startup and refreshed periodically (every 5s) or on admin config change events.
+
+**Changes:**
+
+1. **New: `config_cache` in config.c** — A simple hash map or fixed array of key-value pairs loaded from the config table:
+   ```c
+   typedef struct {
+       char key[64];
+       char value[512];
+   } config_cache_entry_t;
+   
+   static config_cache_entry_t g_config_cache[256];
+   static int g_config_cache_count = 0;
+   static time_t g_config_cache_last_refresh = 0;
+   static pthread_mutex_t g_config_cache_mutex;
+   #define CONFIG_CACHE_TTL_SEC 5
+   ```
+
+2. **Modify `get_config_value_from_table()`** — Instead of querying SQLite, look up in the in-memory cache. If cache is stale, refresh from SQLite (but only once per TTL period, not per call).
+
+3. **Add `config_cache_refresh()`** — Loads all rows from `SELECT key, value FROM config` into the hash map. Called:
+   - Once at startup after config table is populated
+   - Every 5 seconds from the existing `refresh_hot_config_if_needed()` timer
+   - Immediately after `process_admin_event_in_config()` modifies config
+
+4. **Thread safety:** The cache is read from lws-main and event-worker threads. Use a read-write lock or double-buffer pattern. Since config changes are rare, a simple mutex with short hold time is fine.
+
+5. **Remove the existing `hot_config_cache_t`** in websockets.c — it becomes redundant since the global config cache serves the same purpose with broader coverage.
+
+This single change eliminates SQLite calls from:
+- Per-connection: `trust_proxy_headers`, `nip42_auth_required_*` (websockets.c)
+- Per-REQ: `expiration_enabled`, `expiration_filter` (main.c)
+- Per-EVENT: `admin_pubkey`, `relay_pubkey`, `nip42_auth_enabled`, `pow_*` (request_validator.c, nip013.c)
+- Per-broadcast: `expiration_enabled`, `expiration_filter` (subscriptions.c)
+- Per-NIP-11: 25+ config values (nip011.c)
+- Per-NIP-42: `relay_url`, `relay_port` (nip042.c)
+- Per-NIP-40: 5 expiration config values (nip040.c)
+- Per-IP-ban: `idle_ban_*`, `auth_fail_*` config values (ip_ban.c)
+- Per-admin-DM: `relay_pubkey`, `admin_pubkey`, `wot_enabled` (dm_admin.c)
+- Per-monitoring: `relay_pubkey`, throttle values (api.c)
+
+### Fix 2: Move Duplicate Check to Event Worker Thread
+
+**Impact: High** — eliminates the most frequent per-EVENT SQLite call from lws-main
+
+Currently `event_id_exists_in_db()` runs on lws-main before async submission. Move it into the `async_event_worker_main()` function, which already has its own SQLite connection.
+
+**Changes:**
+- Remove `event_id_exists_in_db()` calls from both EVENT paths in websockets.c (lines 1324 and 2134)
+- Add the duplicate check at the start of `async_event_worker_main()` before `nostr_validate_unified_request()`
+- If duplicate found, set `completion->success = 1` and `completion->error_message = "duplicate: already have this event"` and skip crypto
+- The completion handler already sends OK responses, so this works seamlessly
+
+**Trade-off:** Without the early dedup check on lws-main, duplicate events will be submitted to the event worker queue and consume a queue slot + thread wakeup before being detected. This is acceptable because:
+- The worker thread dedup check is still fast (B-tree index lookup)
+- It avoids the much larger cost of running SQLite on lws-main for every event
+- Queue depth is 4096, so even under heavy duplicate traffic this won't overflow
+
+### Fix 3: Make COUNT Queries Async
+
+**Impact: Medium** — eliminates blocking wait on lws-main for NIP-45 COUNT
+
+Currently `handle_count_message()` calls `thread_pool_execute_count_sync()` which blocks lws-main waiting for the db-read worker. Convert to the same async pattern used for REQ queries.
+
+**Changes:**
+- Create `count_async_state_t` similar to `req_async_state_t`
+- Create `count_async_completion_t` with count result
+- Add `submit_count_query_async()` that uses `thread_pool_submit_read()` with a callback
+- The callback pushes to a count completion queue
+- Add `process_count_async_completions()` to drain the queue on lws-main and send COUNT responses
+- Call it from the main event loop alongside `process_req_async_completions()`
+
+### Fix 4: Cache Auth Rules Check Result
+
+**Impact: Low-Medium** — eliminates per-REQ SQLite when WoT is enabled
+
+`check_database_auth_rules()` at websockets.c:1706 runs a SQLite query for every REQ when `wot_enabled == 2`. Cache the result per-session.
+
+**Changes:**
+- Add `wot_checked` and `wot_allowed` fields to `per_session_data`
+- On first REQ, call `check_database_auth_rules()` and cache the result
+- On subsequent REQs from the same session, use the cached value
+- Reset cache when auth state changes (e.g., after NIP-42 AUTH)
+
+### Fix 5: Move Special-Kind EVENT Store to Event Worker
+
+**Impact: Low** — special kinds are rare but currently do full sync store on lws-main
+
+Kinds 14, 1059, and 23456 are currently excluded from async processing because they have special handling. However, the `store_event()` call within those paths still blocks lws-main.
+
+**Changes:**
+- For kind 1059 and kind 14: after special processing completes, submit the store to the event worker instead of calling `store_event()` synchronously
+- For kind 23456: admin events are not stored (processed by admin API), so no change needed
+- This requires the special processing (decryption, admin check) to still happen on lws-main (it needs `pss` context), but the final DB write goes async
+
+### Fix 6: Reduce Reader Threads from 4 to 1
+
+**Impact: Resource savings** — 3 fewer threads, 3 fewer SQLite connections
+
+**Changes:**
+- Change default `reader_threads` in `thread_pool_init()` from 4 to 1
+- Or make it configurable via config with default 1
+- The single `db-read` thread handles all REQ and COUNT queries sequentially
+- If future profiling shows the read thread becoming a bottleneck, increase back to 2+
+
+### Fix 7: Move Subscription Logging Off Main Thread
+
+**Impact: Medium** — eliminates per-REQ INSERT, per-CLOSE UPDATE, per-broadcast UPDATE
+
+The subscription lifecycle functions in subscriptions.c do synchronous SQLite writes on lws-main:
+- `db_log_subscription_created()` — INSERT on every REQ
+- `db_log_subscription_closed()` — INSERT + UPDATE on every CLOSE
+- `db_log_subscription_disconnected()` — UPDATE + INSERT on every disconnect
+- `db_update_subscription_events_sent()` — UPDATE on every broadcast match
+
+**Changes:**
+- Submit these as fire-and-forget write jobs to the db-write thread via `thread_pool_submit_write()`
+- Create a new job type `THREAD_POOL_JOB_SUBSCRIPTION_LOG` or simply use a generic callback job
+- The main thread doesn't need to wait for these to complete — they're purely observational logging
+
+### Fix 8: Move Periodic Tasks Off Main Thread
+
+**Impact: Low** — these run every 60s but can still cause latency spikes
+
+- `generate_and_post_status_event()`: Submit as an async job to the event worker
+- `ip_ban_cleanup()`/`ip_ban_log_stats()`/`ip_ban_save()`: These do SQLite reads/writes. Move to a periodic job on the db-write thread
+- Config cache refresh (Fix 1) replaces the old `refresh_hot_config_if_needed()` SQLite queries
+
+### Fix 9: Cache NIP-11 Response
+
+**Impact: Low-Medium** — eliminates 25+ SQLite SELECTs per NIP-11 HTTP request
+
+`generate_relay_info_json()` in nip011.c calls `get_config_value()` 15 times and `get_config_int()`/`get_config_bool()` 10 times. After Fix 1 (global config cache), these become in-memory lookups. But we can go further:
+
+**Changes:**
+- Cache the serialized NIP-11 JSON response string with a TTL (e.g., 60 seconds)
+- On NIP-11 request, return the cached string directly without rebuilding
+- Invalidate on admin config change events
+
+## Implementation Order
+
+| # | Fix | Risk | Complexity |
+|---|-----|------|------------|
+| 1 | Global config cache (replaces all get_config_* SQLite) | Low | Medium |
+| 2 | Move dedup check to event worker | Low | Low |
+| 3 | Async COUNT queries | Low | Medium |
+| 4 | Cache WoT auth rules per-session | Very Low | Low |
+| 5 | Async store for special kinds | Medium | Medium |
+| 6 | Reduce reader threads to 1 | Very Low | Trivial |
+| 7 | Move subscription logging off main thread | Low | Low-Medium |
+| 8 | Move periodic tasks off main thread | Low | Medium |
+| 9 | Cache NIP-11 response | Very Low | Low |
+
+## Expected Impact
+
+After all 9 fixes, `lws-main` should have **zero direct SQLite calls**. Its work becomes:
+- JSON parse incoming messages (~fast)
+- In-memory subscription matching (~fast)
+- In-memory config lookups (~fast, hash map)
+- Message formatting and queuing (~fast)
+- `lws_service()` I/O (~fast)
+- Draining completion queues (~fast)
+
+### Impact by fix
+
+| Fix | SQLite calls eliminated | Frequency |
+|-----|------------------------|-----------|
+| Fix 1: Global config cache | ~50+ `get_config_*` call sites across 8 files | Per-event, per-connection, per-REQ, per-broadcast, per-NIP-11 |
+| Fix 2: Dedup to event worker | 2 `event_id_exists_in_db()` calls | Per-EVENT |
+| Fix 3: Async COUNT | 1 `thread_pool_execute_count_sync()` | Per-COUNT message |
+| Fix 4: WoT cache per-session | 1 `check_database_auth_rules()` | Per-REQ when WoT enabled |
+| Fix 5: Async special-kind store | ~6 `store_event()` calls | Per special-kind EVENT |

+| Fix 7: Async subscription logging | 4 `db_log_*`/`db_update_*` calls | Per-REQ, per-CLOSE, per-broadcast |
+| Fix 8: Async periodic tasks | `generate_stats_json()`, `ip_ban_*` | Every 60s |
+| Fix 9: Cache NIP-11 | 25+ config lookups per request | Per NIP-11 HTTP request |

+# WAL Checkpoint Fix — db-write Thread CPU Plan
+
+## Problem
+
+Fresh profiling of the production server shows the `db-write` thread consuming **77% average CPU** (peaking at 100%) while `lws-main` sits at 0.3%.
+
+The `perf` callgraph confirms 100% of the hot symbols are SQLite **B-tree read operations** running on the `db-write` thread:
+
+| % CPU | Symbol | Role |
+|-------|--------|------|
+| 13.88 | `sqlite3BtreeTableMoveto` | B-tree seek |
+| 10.05 | `sqlite3VdbeExec` | VM execution |
+| 7.77 | `rep_movs_alternative` | kernel memcpy in pread |
+| 7.76 | `sqlite3GetVarint` | varint decode |
+| 6.66 | `pcache1Fetch` | page cache lookup |
+| 6.02 | `memcpy` | data copy |
+
+These are **read-path** functions, not write-path. The `event-worker` thread accumulated only 3 CPU ticks over 5 minutes, meaning very few events are actually being stored.
+
+## Root Cause
+
+SQLite WAL auto-checkpoint. By default SQLite triggers a checkpoint every 1000 WAL pages. The checkpoint is executed by the **next writer** — which is always the `db-write` thread since all writes are funnelled through it.
+
+A WAL checkpoint reads every dirty page from the WAL file and writes it back to the main database file. This involves B-tree traversals to locate pages, which explains the `BtreeTableMoveto` dominance.
+
+The current `db_open_worker_connection` in `src/db_ops.c` sets `PRAGMA journal_mode=WAL` and `busy_timeout=5000` but does **not** configure `wal_autocheckpoint`. SQLite's default of 1000 pages applies.
+
+In earlier profiling runs the same CPU burn appeared on `lws-main` at 55-67% — because that thread was doing the writes directly before the thread-pool refactoring. The work simply moved threads; the total cost is unchanged.
+
+## Implementation Plan
+
+### Step 1 — Disable auto-checkpoint on the write connection
+
+In `db_open_worker_connection` add:
+
+```c
+sqlite3_exec(db, "PRAGMA wal_autocheckpoint=0;", NULL, NULL, NULL);
+```
+
+This prevents the write thread from ever running a checkpoint inline with normal writes.
+
+### Step 2 — Add a periodic checkpoint job type to the thread pool
+
+Add a new job type `THREAD_POOL_JOB_WAL_CHECKPOINT` to `thread_pool.h`.
+
+The handler in `thread_pool.c` calls:
+
+```c
+sqlite3_wal_checkpoint_v2(db, NULL, SQLITE_CHECKPOINT_PASSIVE, NULL, NULL);
+```
+
+`PASSIVE` mode checkpoints only pages that are not currently being read, so it never blocks readers.
+
+### Step 3 — Submit the checkpoint job on a timer
+
+In the existing 60-second periodic timer in `websockets.c`, add a call to submit a WAL checkpoint job to the write queue:
+
+```c
+thread_pool_submit_wal_checkpoint();
+```
+
+This runs the checkpoint once per minute on the write thread, but as a **bounded, predictable** operation rather than being triggered unpredictably by every INSERT.
+
+### Step 4 — Also disable auto-checkpoint on reader connections
+
+In `db_open_worker_connection`, the same `wal_autocheckpoint=0` applies to reader connections too. Readers can also trigger checkpoints in SQLite; disabling it on all connections ensures only the explicit periodic job does checkpointing.
+
+### Step 5 — Run a TRUNCATE checkpoint at shutdown
+
+In `thread_pool_shutdown`, before closing the write connection, run:
+
+```c
+sqlite3_wal_checkpoint_v2(db, NULL, SQLITE_CHECKPOINT_TRUNCATE, NULL, NULL);
+```
+
+This ensures the WAL is fully flushed and truncated on clean shutdown, keeping the database file compact.
+
+## Files Changed
+
+| File | Change |
+|------|--------|
+| `src/db_ops.c` | Add `PRAGMA wal_autocheckpoint=0` in `db_open_worker_connection` |
+| `src/thread_pool.h` | Add `THREAD_POOL_JOB_WAL_CHECKPOINT` enum value |
+| `src/thread_pool.c` | Add `execute_wal_checkpoint_job` handler; add checkpoint-at-shutdown in `thread_pool_shutdown`; add `thread_pool_submit_wal_checkpoint` helper |
+| `src/websockets.c` | Call `thread_pool_submit_wal_checkpoint()` in the 60-second periodic timer |
+
+## Expected Impact
+
+- `db-write` CPU should drop from ~77% to near 0% when idle (no events to store)
+- Periodic checkpoint bursts of a few seconds every 60s instead of continuous burn
+- No change to data durability — WAL still protects against crashes; checkpoint just moves data from WAL to main DB file
+- Readers are unaffected — PASSIVE checkpoint never blocks them
+
+## Risk
+
+- If the relay crashes between checkpoints, the WAL file may be larger than before (up to 60s of accumulated writes). This is safe — SQLite replays the WAL on next open. The WAL file size is bounded by the write rate, which is low.
+- PASSIVE checkpoint may not checkpoint all pages if readers hold them. This is fine — the next checkpoint will catch up.
+
+## Verification
+
+After deploying, re-run the profiler:
+
+```bash
+./deploy_lt_debug.sh && DURATION=300 INTERVAL=5 ./tests/thread_cpu_profile.sh
+```
+
+Expected: `db-write` avg CPU drops below 5%.

+# Web of Trust (WoT) Implementation Plan
+
+## Feature Description
+
+When enabled, the relay restricts access to pubkeys that the admin follows. The admin's kind 3 (contact list) event is used as the source of truth — all `p` tags in that event become whitelisted pubkeys. The admin themselves is always whitelisted.
+
+Single config variable `wot_enabled` with three levels:
+
+| Value | Mode | Effect |
+|-------|------|--------|
+| `0` | Off | Open relay — anyone can read and write |
+| `1` | Write-only | Only followed pubkeys can **publish** events. Anyone can read/subscribe. |
+| `2` | Full | Only followed pubkeys can **publish AND subscribe**. Requires NIP-42 auth for subscriptions. Eliminates subscription churn from anonymous connections. |
+
+## How It Works
+
+### WoT Sync Flow
+```mermaid

+    G -->|Yes| C
+    G -->|No| H["REJECT: not authorized\nfor subscriptions"]
+```
+
+## Design Decisions
+
+### Leveraging Existing Infrastructure
+
+The relay already has everything needed:
+
+1. **`auth_rules` table** — stores whitelist/blacklist rules with `rule_type`, `pattern_type`, `pattern_value`
+2. **`check_database_auth_rules()`** in [`request_validator.c:529`](src/request_validator.c:529) — already implements the logic: "if whitelist rules exist and pubkey is not whitelisted, deny"
+3. **`add_auth_rule_from_config()`** / **`remove_auth_rule_from_config()`** in [`config.c`](src/config.c:2082) — already manage auth rules
+4. **`event_tags` table** — can efficiently query `p` tags from kind 3 events
+5. **Config system** — `auth_enabled` flag already controls whether auth rules are checked
+6. **NIP-42 auth** — `nip42_auth_required_subscriptions` already gates REQ access, `pss->authenticated_pubkey` stores the authenticated pubkey
+
+### WoT-Specific Whitelist Rules
+
+To distinguish WoT-generated whitelist rules from manually-added ones, we use a new `rule_type` value: `wot_whitelist`. This allows:
+- Clearing all WoT rules without affecting manual whitelist/blacklist rules
+- Querying WoT status separately
+- The existing `check_database_auth_rules()` function already checks for `rule_type = 'whitelist'` — we need to also match `wot_whitelist` in the whitelist check
+
+### Trigger Mechanism
+
+The WoT sync happens when:
+1. **A kind 3 event from the admin is stored** — detected in `store_event()` after successful INSERT
+2. **Startup** — if `wot_enabled > 0`, sync from the most recent admin kind 3 event in the database
+3. **Admin DM command** — `wot sync` to force a manual resync
+
+### What Gets Whitelisted
+
+- All pubkeys in `p` tags of the admin's kind 3 event
+- The admin pubkey itself (always whitelisted)
+- The relay pubkey (always whitelisted — for admin DM responses)
+
+### What Is NOT Blocked
+
+Even with WoT enabled, these are always allowed:
+- Admin events (kind 23456) — already bypassed in [`request_validator.c:303`](src/request_validator.c:303)
+- NIP-42 auth events (kind 22242) — already bypassed in [`request_validator.c:318`](src/request_validator.c:318)
+- Kind 3 events from the admin — needed to update the follow list itself
+- Kind 1059 gift wraps addressed to the relay — needed for admin DMs
+
+## Files to Modify
+
+| File | Changes |
+|------|---------|
+| `src/default_config_event.h` | Add `wot_enabled` config key (default: `0`) |
+| `src/config.c` | Add `wot_sync_from_admin_kind3()` function |
+| `src/main.c` | Add WoT trigger in `store_event()` when admin kind 3 is stored, add startup WoT sync |
+| `src/request_validator.c` | Update whitelist SQL to also match `wot_whitelist` rule type |
+| `src/sql_schema.h` | Update `auth_rules` CHECK constraint to include `wot_whitelist` |
+| `src/websockets.c` | Add WoT pubkey check after NIP-42 auth check in REQ handler |
+| `src/dm_admin.c` | Add `wot 0`, `wot 1`, `wot 2`, `wot sync`, `wot status` DM commands |
+
+## Detailed Changes
+
+### 1. Schema: `src/sql_schema.h`
+
+Update the `auth_rules` table CHECK constraint to allow `wot_whitelist`:
+
+```sql
+-- Before:
+rule_type TEXT NOT NULL CHECK (rule_type IN ('whitelist', 'blacklist', 'rate_limit', 'auth_required'))
+
+-- After:
+rule_type TEXT NOT NULL CHECK (rule_type IN ('whitelist', 'blacklist', 'rate_limit', 'auth_required', 'wot_whitelist'))
+```
+
+### 2. Config: `src/default_config_event.h`
+
+Add WoT configuration:
+
+```c
+// Web of Trust Settings
+// 0 = off, 1 = write-only (followed pubkeys can publish), 2 = full (followed pubkeys can publish AND subscribe)
+{"wot_enabled", "0"},
+```
+
+### 3. Core WoT Sync Function: `src/config.c`
+
+New function `wot_sync_from_admin_kind3()`:
+
+```c
+int wot_sync_from_admin_kind3(void) {
+    int wot_level = get_config_int("wot_enabled", 0);
+    if (wot_level <= 0) return 0; // WoT disabled
+
+    // 1. Get admin pubkey from config
+    // 2. Query event_tags for p tags from admin's latest kind 3 event:
+    //    SELECT DISTINCT et.tag_value FROM event_tags et
+    //    JOIN events e ON et.event_id = e.id
+    //    WHERE e.kind = 3 AND e.pubkey = ? AND et.tag_name = 'p'
+    //    ORDER BY e.created_at DESC
+    // 3. BEGIN TRANSACTION
+    // 4. DELETE FROM auth_rules WHERE rule_type = 'wot_whitelist'
+    // 5. INSERT wot_whitelist for admin pubkey
+    // 6. INSERT wot_whitelist for relay pubkey
+    // 7. For each p tag: INSERT INTO auth_rules (rule_type, pattern_type, pattern_value)
+    //    VALUES ('wot_whitelist', 'pubkey', ?)
+    // 8. COMMIT
+    // 9. Set auth_enabled = true
+    // 10. If wot_level == 2: set nip42_auth_required_subscriptions = true
+    // 11. Log count of whitelisted pubkeys
+    return 0;
+}
+```
+
+### 4. Trigger on Kind 3 Store: `src/main.c`
+
+In `store_event()`, after successful INSERT and after `store_event_tags()`:
+
+```c
+// Check if this is a kind 3 event from the admin — trigger WoT sync
+if ((int)cJSON_GetNumberValue(kind) == 3) {
+    int wot_level = get_config_int("wot_enabled", 0);
+    if (wot_level > 0) {
+        const char* admin_pubkey = get_config_value("admin_pubkey");
+        if (admin_pubkey && strcmp(cJSON_GetStringValue(pubkey), admin_pubkey) == 0) {
+            DEBUG_INFO("Admin kind 3 event stored — triggering WoT sync");
+            wot_sync_from_admin_kind3();
+        }
+        if (admin_pubkey) free((char*)admin_pubkey);
+    }
+}
+```
+
+### 5. Startup WoT Sync: `src/main.c`
+
+In `main()`, after `populate_event_tags_from_existing()`:
+
+```c
+// Sync Web of Trust whitelist if enabled
+int wot_level = get_config_int("wot_enabled", 0);
+if (wot_level > 0) {
+    wot_sync_from_admin_kind3();
+}
+```
+
+### 6. Update Whitelist Check: `src/request_validator.c`
+
+Update the whitelist SQL queries to also match `wot_whitelist`:
+
+```c
+// Before:
+"SELECT rule_type FROM auth_rules WHERE rule_type = 'whitelist' AND pattern_type = 'pubkey' AND pattern_value = ? AND active = 1 LIMIT 1"
+
+// After:
+"SELECT rule_type FROM auth_rules WHERE rule_type IN ('whitelist', 'wot_whitelist') AND pattern_type = 'pubkey' AND pattern_value = ? AND active = 1 LIMIT 1"
+```
+
+And the whitelist-exists check:
+```c
+// Before:
+"SELECT COUNT(*) FROM auth_rules WHERE rule_type = 'whitelist' AND pattern_type = 'pubkey' AND active = 1 LIMIT 1"
+
+// After:
+"SELECT COUNT(*) FROM auth_rules WHERE rule_type IN ('whitelist', 'wot_whitelist') AND pattern_type = 'pubkey' AND active = 1 LIMIT 1"
+```
+
+### 7. REQ Handler WoT Check: `src/websockets.c`
+
+When `wot_enabled == 2`, add a pubkey whitelist check **after** the existing NIP-42 auth check in the REQ handler. The existing code at line 903 already requires NIP-42 auth when `nip42_auth_required_subscriptions` is set. We add a WoT check right after:
+
+```c
+// Existing NIP-42 auth check (line 903):
+if (pss && pss->nip42_auth_required_subscriptions && !pss->authenticated) {
+    // ... send AUTH challenge or NOTICE ...
+    return 0;
+}
+
+// NEW: WoT read restriction check (wot_enabled == 2)
+if (pss && pss->authenticated && get_config_int("wot_enabled", 0) == 2) {
+    // Client is authenticated — check if their pubkey is in the WoT whitelist
+    int wot_result = check_database_auth_rules(pss->authenticated_pubkey, "subscription", NULL);
+    if (wot_result != NOSTR_SUCCESS) {
+        send_notice_message(wsi, pss, "restricted: your pubkey is not in this relay's web of trust");
+        DEBUG_INFO("REQ rejected: pubkey %s not in WoT whitelist", pss->authenticated_pubkey);
+        cJSON_Delete(json);
+        return 0;
+    }
+}
+```
+
+### 8. Admin DM Commands: `src/dm_admin.c`
+
+Add plain text DM commands:
+
+| Command | Action |
+|---------|--------|
+| `wot 0` or `wot off` | Disable WoT, delete all `wot_whitelist` rules, reset `nip42_auth_required_subscriptions` |
+| `wot 1` or `wot write` | Write-only WoT — sync follow list, set `auth_enabled=true` |
+| `wot 2` or `wot full` | Full WoT — sync follow list, set `auth_enabled=true`, set `nip42_auth_required_subscriptions=true` |
+| `wot sync` | Force resync from admin's kind 3 event |
+| `wot status` | Show WoT level (0/1/2), count of whitelisted pubkeys |
+
+### 9. NIP-11 Update
+
+When WoT is enabled (level 1 or 2), the relay should indicate this in NIP-11 relay info. Add to the `limitation` object:
+```json
+"auth_required": true
+```
+
+## Edge Cases
+
+1. **Admin has no kind 3 event in database**: WoT sync does nothing, logs a warning. No whitelist rules created = open relay.
+
+2. **Admin updates follow list**: New kind 3 event triggers full resync — old WoT rules are cleared, new ones inserted. This is atomic (transaction).
+
+3. **WoT disabled (set to 0)**: Clears all `wot_whitelist` rules. Manual `whitelist` rules are preserved. `nip42_auth_required_subscriptions` is reset to false.
+
+4. **Admin unfollows someone**: Next kind 3 event triggers resync, the unfollowed pubkey's `wot_whitelist` rule is removed (full clear + reinsert).
+
+5. **Kind 1059 gift wraps**: These need special handling — the relay needs to accept gift wraps addressed to it even from non-whitelisted pubkeys (for admin DMs). The `is_nip17_gift_wrap_for_relay()` check should bypass WoT.
+
+6. **Read restriction without NIP-42 support (level 2)**: If a client doesn't support NIP-42, they cannot authenticate and therefore cannot subscribe. This is by design — it's the most effective way to reduce subscription churn from anonymous connections.
+
+7. **NIP-11 discovery**: Clients can check NIP-11 to see if `auth_required` is true before connecting, avoiding wasted connections.
+
+8. **Changing level from 2 to 1**: `nip42_auth_required_subscriptions` is reset to false, allowing anonymous subscriptions again. WoT whitelist rules remain for write restriction.
+
+## Testing Strategy
+
+1. Enable write-only WoT via DM: `wot 1`
+2. Verify admin can still publish events
+3. Verify followed pubkeys can publish events
+4. Verify non-followed pubkeys are rejected for EVENT
+5. Verify non-followed pubkeys can still subscribe (REQ)
+6. Enable full WoT via DM: `wot 2`
+7. Verify unauthenticated clients get AUTH challenge on REQ
+8. Verify authenticated non-followed pubkeys are rejected for REQ
+9. Verify authenticated followed pubkeys can subscribe
+10. Verify `wot status` shows correct level and count
+11. Publish new kind 3 event, verify auto-resync
+12. `wot 0` — verify all pubkeys can publish and subscribe again
+13. Verify admin DMs still work when WoT is enabled
+
+## Performance Considerations
+
+- WoT sync is O(n) where n = number of follows (typically 100-2000)
+- Uses a transaction for bulk insert — fast even for large follow lists
+- Auth rule check is already indexed: `idx_auth_rules_pattern ON auth_rules(pattern_type, pattern_value)`
+- No additional per-event overhead — the existing `check_database_auth_rules()` already runs on every event when auth is enabled
+- **Level 2 directly addresses CPU load**: With `wot_enabled=2`, unauthenticated connections cannot create subscriptions, eliminating the ~120 REQ/minute churn from anonymous connections that was causing 99% CPU

+# Web of Trust — Admin Web UI Plan
+
+## Overview
+
+Add a **Web of Trust** section to the existing Authorization page in the admin web interface. The section lets the admin see whether their kind 3 contact list is on the relay, select a WoT level, trigger a sync, and view the current whitelist count.
+
+## Architecture
+
+### Data Flow
+
+```mermaid
+flowchart LR
+    A[Web UI] -->|config_set wot_enabled N| B[Kind 23456 Event]
+    A -->|system_command wot_sync| B
+    A -->|system_command wot_status| B
+    B --> C[Relay Backend]
+    C -->|Kind 23457 Response| D[Web UI updates display]
+```
+
+### How It Works
+
+1. **On page load** — the Authorization page already calls `loadAuthRules`. We add a parallel call to `loadWotStatus` which sends a `system_command` / `wot_status` event.
+2. **Backend responds** with a kind 23457 JSON containing: `wot_enabled` level, `wot_whitelist_count`, and `admin_kind3_exists` boolean.
+3. **UI renders** a card showing:
+   - Whether the admin's kind 3 event exists on the relay
+   - Current WoT level as a 3-option radio/button group
+   - Count of whitelisted pubkeys
+   - A SYNC button to force resync
+4. **Changing level** sends `config_set` / `wot_enabled` / `0|1|2` via the existing admin API, then triggers `wot_sync` if level > 0.
+5. **SYNC button** sends `system_command` / `wot_sync`.
+
+## Detailed Changes
+
+### 1. Backend: New system commands in `src/config.c`
+
+Add two new branches to `handle_system_command_unified`:
+
+#### `wot_status` command
+
+Returns JSON response:
+```json
+{
+  "command": "wot_status",
+  "status": "success",
+  "wot_enabled": 2,
+  "admin_kind3_exists": true,
+  "wot_whitelist_count": 347,
+  "timestamp": 1234567890
+}
+```
+
+Implementation:
+- Read `wot_enabled` from config table
+- Query `SELECT COUNT(*) FROM events WHERE kind = 3 AND pubkey = ?` with admin_pubkey to check kind 3 existence
+- Query `SELECT COUNT(*) FROM auth_rules WHERE rule_type = 'wot_whitelist' AND active = 1` for whitelist count
+- Return as kind 23457 signed response
+
+#### `wot_sync` command
+
+Calls `wot_sync_from_admin_kind3` and returns result:
+```json
+{
+  "command": "wot_sync",
+  "status": "success",
+  "wot_whitelist_count": 347,
+  "timestamp": 1234567890
+}
+```
+
+### 2. Backend: Hook `config_set` for `wot_enabled`
+
+In `handle_config_set_unified`, after the config value is updated, add a check:
+```c
+// After successful update, trigger WoT sync if wot_enabled changed
+if (strcmp(config_key, "wot_enabled") == 0) {
+    int new_level = atoi(config_value);
+    if (new_level > 0) {
+        wot_sync_from_admin_kind3();
+    } else {
+        // Level 0: clear wot_whitelist rules and reset auth flags
+        sqlite3_exec(g_db, "DELETE FROM auth_rules WHERE rule_type = 'wot_whitelist'", NULL, NULL, NULL);
+        update_config_in_table("nip42_auth_required_subscriptions", "false");
+    }
+}
+```
+
+### 3. Frontend: HTML — WoT section in `api/index.html`
+
+Add a new div **inside** the `authRulesSection`, before the auth rules table. This keeps WoT visually grouped with authorization:
+
+```html
+<!-- Web of Trust Section -->
+<div id="wotSection" class="input-group">
+    <div class="section-header" style="font-size: 14px; margin-bottom: 10px;">
+        WEB OF TRUST
+    </div>
+    
+    <!-- Kind 3 Status Indicator -->
+    <div id="wotKind3Status" class="wot-status-row">
+        <span>Admin Contact List (kind 3):</span>
+        <span id="wotKind3Indicator" class="wot-indicator wot-unknown">Checking...</span>
+    </div>
+    
+    <!-- WoT Level Selector -->
+    <div class="wot-level-selector">
+        <label>WoT Level:</label>
+        <div class="inline-buttons">
+            <button type="button" id="wotLevel0Btn" class="wot-level-btn" onclick="setWotLevel(0)">
+                OFF
+            </button>
+            <button type="button" id="wotLevel1Btn" class="wot-level-btn" onclick="setWotLevel(1)">
+                WRITE ONLY
+            </button>
+            <button type="button" id="wotLevel2Btn" class="wot-level-btn" onclick="setWotLevel(2)">
+                FULL
+            </button>
+        </div>
+        <div class="wot-level-description" id="wotLevelDescription">
+            Level 0: Open relay — anyone can read and write
+        </div>
+    </div>
+    
+    <!-- WoT Stats -->
+    <div class="wot-stats-row">
+        <span>Whitelisted Pubkeys:</span>
+        <span id="wotWhitelistCount">—</span>
+    </div>
+    
+    <!-- Sync Button -->
+    <div class="inline-buttons">
+        <button type="button" id="wotSyncBtn" onclick="syncWot()">SYNC FROM KIND 3</button>
+        <button type="button" id="wotRefreshBtn" onclick="loadWotStatus()">REFRESH STATUS</button>
+    </div>
+</div>
+
+<hr style="margin: 15px 0; border-color: var(--border-color);">
+```
+
+### 4. Frontend: CSS additions in `api/index.css`
+
+```css

+    display: flex;
+    justify-content: space-between;

+```
+
+### 5. Frontend: JavaScript functions in `api/index.js`
+
+#### `loadWotStatus` — query current WoT state
+
+```javascript
+async function loadWotStatus() {
+    try {
+        if (!isLoggedIn || !userPubkey || !relayPool) return;
+        
+        const command_array = ["system_command", "wot_status"];
+        const encrypted_content = await encryptForRelay(JSON.stringify(command_array));
+        if (!encrypted_content) return;
+        
+        const event = {
+            kind: 23456,
+            pubkey: userPubkey,
+            created_at: Math.floor(Date.now() / 1000),
+            tags: [["p", getRelayPubkey()]],
+            content: encrypted_content
+        };
+        
+        const signedEvent = await window.nostr.signEvent(event);
+        const url = relayConnectionUrl.value.trim();
+        await relayPool.publish([url], signedEvent);
+        
+        log('WoT status query sent', 'INFO');
+    } catch (error) {
+        log('Failed to load WoT status: ' + error.message, 'ERROR');
+    }
+}
+```
+
+#### `setWotLevel` — change WoT level via config_set
+
+```javascript
+async function setWotLevel(level) {
+    try {
+        if (!isLoggedIn || !userPubkey || !relayPool) return;
+        
+        // Send config_set for wot_enabled
+        const command_array = ["config_set", "wot_enabled", String(level)];
+        const encrypted_content = await encryptForRelay(JSON.stringify(command_array));
+        if (!encrypted_content) return;
+        
+        const event = {
+            kind: 23456,
+            pubkey: userPubkey,
+            created_at: Math.floor(Date.now() / 1000),
+            tags: [["p", getRelayPubkey()]],
+            content: encrypted_content
+        };
+        
+        const signedEvent = await window.nostr.signEvent(event);
+        const url = relayConnectionUrl.value.trim();
+        await relayPool.publish([url], signedEvent);
+        
+        log('WoT level set to ' + level, 'INFO');
+        
+        // Refresh status after a short delay
+        setTimeout(() => loadWotStatus(), 1500);
+    } catch (error) {
+        log('Failed to set WoT level: ' + error.message, 'ERROR');
+    }
+}
+```
+
+#### `syncWot` — force WoT sync
+
+```javascript
+async function syncWot() {
+    try {
+        if (!isLoggedIn || !userPubkey || !relayPool) return;
+        
+        const command_array = ["system_command", "wot_sync"];
+        const encrypted_content = await encryptForRelay(JSON.stringify(command_array));
+        if (!encrypted_content) return;
+        
+        const event = {
+            kind: 23456,
+            pubkey: userPubkey,
+            created_at: Math.floor(Date.now() / 1000),
+            tags: [["p", getRelayPubkey()]],
+            content: encrypted_content
+        };
+        
+        const signedEvent = await window.nostr.signEvent(event);
+        const url = relayConnectionUrl.value.trim();
+        await relayPool.publish([url], signedEvent);
+        
+        log('WoT sync command sent', 'INFO');
+        
+        // Refresh status after sync completes
+        setTimeout(() => loadWotStatus(), 2000);
+    } catch (error) {
+        log('Failed to sync WoT: ' + error.message, 'ERROR');
+    }
+}
+```
+
+#### `handleWotStatusResponse` — process backend response
+
+```javascript
+function handleWotStatusResponse(responseData) {
+    const kind3Indicator = document.getElementById('wotKind3Indicator');
+    const whitelistCount = document.getElementById('wotWhitelistCount');
+    const levelDesc = document.getElementById('wotLevelDescription');
+    
+    // Update kind 3 indicator
+    if (kind3Indicator) {
+        if (responseData.admin_kind3_exists) {
+            kind3Indicator.textContent = 'Found ✓';
+            kind3Indicator.className = 'wot-indicator wot-found';
+        } else {
+            kind3Indicator.textContent = 'Not Found ✗';
+            kind3Indicator.className = 'wot-indicator wot-missing';
+        }
+    }
+    
+    // Update whitelist count
+    if (whitelistCount) {
+        whitelistCount.textContent = responseData.wot_whitelist_count || 0;
+    }
+    
+    // Update level buttons
+    const level = responseData.wot_enabled || 0;
+    ['wotLevel0Btn', 'wotLevel1Btn', 'wotLevel2Btn'].forEach((id, i) => {
+        const btn = document.getElementById(id);
+        if (btn) {
+            btn.classList.toggle('active', i === level);
+        }
+    });
+    
+    // Update description
+    const descriptions = [
+        'Level 0: Open relay — anyone can read and write',
+        'Level 1: Write-only — only followed pubkeys can publish events',
+        'Level 2: Full — only followed pubkeys can publish AND subscribe (NIP-42 required)'
+    ];
+    if (levelDesc) {
+        levelDesc.textContent = descriptions[level] || descriptions[0];
+    }
+    
+    // Enable/disable sync button based on kind 3 existence
+    const syncBtn = document.getElementById('wotSyncBtn');
+    if (syncBtn) {
+        syncBtn.disabled = !responseData.admin_kind3_exists;
+    }
+}
+```
+
+#### Wire into existing response handler
+
+In the existing `handleSystemCommandResponse` function, add:
+```javascript
+if (responseData.command === 'wot_status' || responseData.command === 'wot_sync') {
+    handleWotStatusResponse(responseData);
+}
+```
+
+#### Wire into page navigation
+
+In the `authorization` case of the page switch handler, add:
+```javascript
+case 'authorization':
+    loadAuthRules().catch(...);
+    loadWotStatus().catch(error => {
+        console.log('Auto-load WoT status failed: ' + error.message);
+    });
+    break;
+```
+
+## Files to Modify
+
+| File | Changes |
+|------|---------|
+| `src/config.c` | Add `wot_status` and `wot_sync` branches to `handle_system_command_unified`; add WoT sync hook to `handle_config_set_unified` |
+| `api/index.html` | Add WoT section HTML inside `authRulesSection` |
+| `api/index.css` | Add WoT-specific CSS styles |
+| `api/index.js` | Add `loadWotStatus`, `setWotLevel`, `syncWot`, `handleWotStatusResponse` functions; wire into page nav and response handler |
+
+## Edge Cases
+
+1. **Admin not logged in** — WoT section shows but buttons are disabled; status shows "Checking..."
+2. **No kind 3 event** — Indicator shows red "Not Found ✗"; SYNC button is disabled; level selector still works but sync will whitelist only admin + relay
+3. **Level change from 2 to 0** — Backend clears all wot_whitelist rules and resets nip42_auth_required_subscriptions
+4. **Concurrent config_set and wot_sync** — The backend handles these sequentially via SQLite transactions; no race condition
+

+ * NIP-17 Private Direct Messages - Command Line Application
+ *
+ * This example demonstrates how to send NIP-17 private direct messages
+ * using the Nostr Core Library.
+ *
+ * Usage:
+ *   ./send_nip17_dm -r <recipient> -s <sender> [-R <relay>]... <message>
+ *
+ * Options:
+ *   -r <recipient>: The recipient's public key (npub or hex)
+ *   -s <sender>: The sender's private key (nsec or hex)
+ *   -R <relay>: Relay URL to send to (can be specified multiple times)
+ *   <message>: The message to send (must be the last argument)
+ *
+ * If no relays are specified, uses default relay.
+ * If no sender key is provided, uses a default test key.
+ *
+ * Examples:
+ *   ./send_nip17_dm -r npub1example... -s nsec1test... -R wss://relay1.com "Hello from NIP-17!"
+ *   ./send_nip17_dm -r 4f355bdcb7cc0af728ef3cceb9615d90684bb5b2ca5f859ab0f0b704075871aa -s aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa -R ws://localhost:8888 "config"

Your Name	c0051b22be	v1.1.7 - Add per-connection database query tracking for abuse detection Implemented comprehensive database query tracking to identify clients causing high CPU usage through excessive database queries. The relay now tracks and displays query statistics per WebSocket connection in the admin UI. Features Added: - Track db_queries_executed and db_rows_returned per connection - Calculate query rate (queries/minute) and row rate (rows/minute) - Display stats in admin UI grouped by IP address and WebSocket - Show: IP, Subscriptions, Queries, Rows, Query Rate, Duration Implementation: - Added tracking fields to per_session_data structure - Increment counters in handle_req_message() and handle_count_message() - Extract stats from pss in query_subscription_details() - Updated admin UI to display IP address and query metrics Use Case: Admins can now identify abusive clients by monitoring: - High query rates (>50 queries/min indicates polling abuse) - High row counts (>10K rows/min indicates broad filter abuse) - Query patterns (high queries + low rows = targeted, high both = crawler) This enables informed decisions about which IPs to blacklist based on actual resource consumption rather than just connection count.	2026-02-01 16:26:37 -04:00
Your Name	4cc2d2376e	v1.1.6 - Optimize: Deduplicate kinds in subscription index to prevent redundant operations The kind index was adding subscriptions multiple times when filters contained duplicate kinds (e.g., 'kinds': [1, 1, 1] or multiple filters with same kind). This caused: - Redundant malloc/free operations during add/remove - Multiple index entries for same subscription+kind pair - Excessive TRACE logging (7+ removals for single subscription) - Wasted CPU cycles on duplicate operations Fix: - Added bitmap-based deduplication in add_subscription_to_kind_index() - Uses 8KB bitmap (65536 bits) to track which kinds already added - Prevents adding same subscription to same kind index multiple times - Reduces index operations by 3-10x for subscriptions with duplicate kinds Performance Impact: - Eliminates redundant malloc/free cycles - Reduces lock contention on kind index operations - Decreases log volume significantly - Should reduce CPU usage by 20-40% under production load	2026-02-01 15:59:54 -04:00
Your Name	30dc4bf67d	v1.1.5 - Fix CRITICAL segfault: Use wrapper nodes for no-kind-filter subscriptions The kind index optimization in v1.1.4 introduced a critical bug that caused segmentation faults in production. The bug was in add_subscription_to_kind_index() which directly assigned sub->next for no-kind-filter subscriptions, corrupting the main active_subscriptions linked list. Root Cause: - subscription_t has only ONE 'next' pointer used by active_subscriptions list - Code tried to reuse 'next' for no_kind_filter_subs list - This overwrote the active_subscriptions linkage, breaking list traversal - Result: segfaults when iterating subscriptions Fix: - Added no_kind_filter_node_t wrapper structure (like kind_subscription_node_t) - Changed no_kind_filter_subs from subscription_t* to no_kind_filter_node_t* - Updated add/remove functions to use wrapper nodes - Updated broadcast function to iterate through wrapper nodes This follows the same pattern already used for kind_index entries and prevents any corruption of the subscription structure's next pointer.	2026-02-01 12:37:07 -04:00
Your Name	a1928cc5d7	v1.1.4 - Add kind-based index for 10x subscription matching performance improvement	2026-02-01 11:15:26 -04:00

Your Name	11b0a88cdd	v1.1.2 - Fix hardcoded version string in print_version() - use VERSION define from main.h The print_version() function was displaying a hardcoded 'v1.0.0' string instead of using the VERSION define from main.h. This caused version mismatches where the git tag and main.h showed v1.1.1 but the binary reported v1.0.0. Now print_version() uses the VERSION macro, ensuring all version displays are consistent and automatically updated when increment_and_push.sh updates main.h.	2026-01-31 16:48:11 -04:00
Your Name	e8f8e3b0cf	v1.1.1 - Fix NOTICE message silent failure - add pss parameter to send_notice_message() Previously, send_notice_message() called queue_message() with NULL pss, causing all NOTICE messages to fail silently. This affected filter validation errors (e.g., invalid kinds > 65535 per NIP-01) where clients received no response. Changes: - Updated send_notice_message() signature to accept struct per_session_data* pss - Updated 37 call sites across websockets.c (31) and nip042.c (6) - Updated forward declarations in main.c, websockets.c, and nip042.c - Added tests/invalid_kind_test.sh to verify NOTICE responses for invalid filters Fixes issue where REQ with kinds:[99999] received no response instead of NOTICE.	2026-01-31 15:48:29 -04:00
