+# 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
+```

+# 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).
+

+    end
+```
+
+---
+
+## 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

+    }
+}
+```
+
+**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
+

+    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
+

+    participant I1_NEW as Instance 1 - v1.1
+

+```
+
+Rolling deploy script:

+# 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

+|------|-------------------|------------|
+| [`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

+
+### 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
+
+```
+lws-main thread:
+  - WebSocket protocol handling

+### 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

+# 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

+
+    // Reset window if expired

+    }
+
+    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;

+
+        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 (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) {
+    // Use separate idle failure recording (has its own threshold/duration)
+    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 &&
+         (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);
+}
+```
+
+### 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) {
+    if (!is_valid_positive_integer(value)) {
+        snprintf(error_msg, error_size, "invalid idle_ban_threshold '%s' (must be positive integer)", value);
+        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)) {
+        snprintf(error_msg, error_size, "invalid idle_ban_window_sec '%s' (must be positive integer)", value);
+        return -1;
+    }
+    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) {
+    if (!is_valid_positive_integer(value)) {
+        snprintf(error_msg, error_size, "invalid idle_ban_duration_sec '%s' (must be positive integer)", value);
+        return -1;
+    }
+    int duration = atoi(value);
+    if (duration < 60 || duration > 86400) {
+        snprintf(error_msg, error_size, "idle_ban_duration_sec must be between 60 and 86400");
+        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.";
+} else if (strcmp(key, "idle_ban_window_sec") == 0) {
+    description = "Time window in seconds for counting idle failures.";
+} else if (strcmp(key, "idle_ban_duration_sec") == 0) {
+    description = "Initial ban duration in seconds for idle failures (doubles each time).";
+}
+```
+
+### 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/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

+```
+
+### 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** |
+
+#### `config.c` — Called on EVERY event kind check
+
+| 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"'`
+
+---
+
+## Implementation Priority Order
+
+| Priority | Task | Impact |
+|----------|------|--------|
+| P0 | Fix `is_nip42_auth_required_for_kind()` leak in config.c:377 | Called on every event |
+| P0 | Fix `ip_is_whitelisted()` leak in ip_ban.c:255 | Called on every connection check |
+| P0 | Fix `is_authorized_admin_event()` leaks in main.c:1718,1742 | Called per admin event, leaks in loop |
+| P1 | Fix websockets.c:1527,1549 auth bypass leaks | Called on every event with auth |
+| P1 | Fix request_validator.c:304,320 leaks | Called on every event validation |
+| P1 | Fix nip042.c:99 relay_url leak | Called on every NIP-42 auth |
+| P2 | Implement config cache for hot-path values | Eliminates leak class entirely |
+| P2 | Fix inactive subscription cleanup in CLOSED handler | Prevents slow subscription leak |

+# 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.

+Nostr-Relay-NestJS features a hybrid storage model where tags are stored both in a JSONB field (for general lookup) and a normalized `generic_tags` table (for optimized tag query performance). The schema uses Kysely for type-safe interaction.

+# 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

+
+## 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 |
+|------|----------|-----------|------|
+| `event_id_exists_in_db()` | websockets.c:1324, 2134 | Every EVENT | ~10-50us per B-tree lookup |
+| `get_config_value("relay_pubkey")` | websockets.c:2050 | Every kind-14 EVENT | SQLite SELECT |
+| `get_config_value("admin_pubkey")` | websockets.c:2073 | Every kind-23456 EVENT | SQLite SELECT |
+
+### Hot Path — Per-Connection (every new WebSocket connection)
+
+| Call | Location | Frequency | Cost |

+| `ip_ban_cleanup/log_stats` | websockets.c:3004-3005 | Every 60s | SQLite reads/writes |
+
+### 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 6: Reduce readers | N/A (resource savings) | N/A |
+| 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 |
+
+Estimated main-thread CPU reduction: from **54% to ~5-10%** (mostly WebSocket I/O, subscription matching, and JSON parsing).

+# 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%.
