 # Changelog

+## 2026-02-19 - 25.7.4 - fix(smart-proxy)
+include proxy IPs in smart proxy configuration
+
+- Add proxyIps: this.settings.proxyIPs to proxy options in ts/proxies/smart-proxy/smart-proxy.ts
+- Ensures proxy IPs from settings are passed into the proxy implementation (enables proxy IP filtering/whitelisting)
+
+## 2026-02-16 - 25.7.3 - fix(metrics)
+centralize connection-closed reporting via ConnectionGuard and remove duplicate explicit metrics.connection_closed calls
+
+- Removed numerous explicit metrics.connection_closed calls from rust/crates/rustproxy-http/src/proxy_service.rs so connection teardown and byte counting are handled by the connection guard / counting body instead of ad-hoc calls.
+- Simplified ConnectionGuard in rust/crates/rustproxy-passthrough/src/tcp_listener.rs: removed the disarm flag and disarm() method so Drop always reports connection_closed.
+- Stopped disarming the TCP-level guard when handing connections off to HTTP proxy paths (HTTP/WebSocket/streaming flows) to avoid missing or double-reporting metrics.
+- Fixes incorrect/duplicate connection-closed metric emission and ensures consistent byte/connection accounting during streaming and WebSocket upgrades.
+
+## 2026-02-16 - 25.7.2 - fix(rustproxy-http)
+preserve original Host header when proxying and add X-Forwarded-* headers; add TLS WebSocket echo backend helper and integration test for terminate-and-reencrypt websocket
+
+- Preserve the client's original Host header instead of replacing it with backend host:port when proxying requests.
+- Add standard reverse-proxy headers: X-Forwarded-For (appends client IP), X-Forwarded-Host, and X-Forwarded-Proto for upstream requests.
+- Ensure raw TCP/HTTP upstream requests copy original headers and skip X-Forwarded-* (which are added explicitly).
+- Add start_tls_ws_echo_backend test helper to start a TLS WebSocket echo backend for tests.
+- Add integration test test_terminate_and_reencrypt_websocket to verify WS upgrade through terminate-and-reencrypt TLS path.
+- Rename unused parameter upstream to _upstream in proxy_service functions to avoid warnings.
+
+## 2026-02-16 - 25.7.1 - fix(proxy)
+use TLS to backends for terminate-and-reencrypt routes
+
+- Set upstream.use_tls = true when a route's TLS mode is TerminateAndReencrypt so the proxy re-encrypts to backend servers.
+- Add start_tls_http_backend test helper and update integration tests to run TLS-enabled backend servers validating re-encryption behavior.
+- Make the selected upstream mutable to allow toggling the use_tls flag during request handling.
+
+## 2026-02-16 - 25.7.0 - feat(routes)
+add protocol-based route matching and ensure terminate-and-reencrypt routes HTTP through the full HTTP proxy; update docs and tests
+
+- Introduce a new 'protocol' match field for routes (supports 'http' and 'tcp') and preserve it through cloning/merging.
+- Add Rust integration test verifying terminate-and-reencrypt decrypts TLS and routes HTTP traffic via the HTTP proxy (per-request Host/path routing) instead of raw tunneling.
+- Add TypeScript unit tests covering protocol field validation, preservation, interaction with terminate-and-reencrypt, cloning, merging, and matching behavior.
+- Update README with a Protocol-Specific Routing section and clarify terminate-and-reencrypt behavior (HTTP routed via HTTP proxy; non-HTTP uses raw TLS-to-TLS tunnel).
+- Example config: include health check thresholds (unhealthyThreshold and healthyThreshold) in the sample healthCheck settings.
+
+## 2026-02-16 - 25.6.0 - feat(rustproxy)
+add protocol-based routing and backend TLS re-encryption support
+
+- Introduce optional route_match.protocol ("http" | "tcp") in Rust and TypeScript route types to allow protocol-restricted routing.
+- RouteManager: respect protocol field during matching and treat TLS connections without SNI as not matching domain-restricted routes (except wildcard-only routes).
+- HTTP proxy: add BackendStream abstraction to unify plain TCP and tokio-rustls TLS backend streams, and support connecting to upstreams over TLS (upstream.use_tls) with an InsecureBackendVerifier for internal/self-signed backends.
+- WebSocket and HTTP forwarding updated to use BackendStream so upstream TLS is handled transparently.
+- Passthrough listener: perform post-termination protocol detection for TerminateAndReencrypt; route HTTP flows into HttpProxyService and handle non-HTTP as TLS-to-TLS tunnel.
+- Add tests for protocol matching, TLS/no-SNI behavior, and other routing edge cases.
+- Add rustls and tokio-rustls dependencies (Cargo.toml/Cargo.lock updates).
+
+## 2026-02-16 - 25.5.0 - feat(tls)
+add shared TLS acceptor with SNI resolver and session resumption; prefer shared acceptor and fall back to per-connection when routes specify custom TLS versions
+
+- Add CertResolver that pre-parses PEM certs/keys into CertifiedKey instances for SNI-based lookup and cheap runtime resolution
+- Introduce build_shared_tls_acceptor to create a shared ServerConfig with session cache (4096) and Ticketer for session ticket resumption
+- Add ArcSwap<Option<TlsAcceptor>> shared_tls_acceptor to tcp_listener for hot-reloadable, pre-built acceptor and update accept loop/handlers to use it
+- set_tls_configs now attempts to build and store the shared TLS acceptor, falling back to per-connection acceptors on failure; raw PEM configs are still retained for route-level fallbacks
+- Add get_tls_acceptor helper: prefer shared acceptor for performance and session resumption, but build per-connection acceptor when a route requests custom TLS versions
+
+## 2026-02-16 - 25.4.0 - feat(rustproxy)
+support dynamically loaded TLS certificates via loadCertificate IPC and include them in listener TLS configs for rebuilds and hot-swap
+
+- Adds loaded_certs: HashMap<String, TlsCertConfig> to RustProxy to store certificates loaded at runtime
+- Merge loaded_certs into tls_configs in rebuild and listener hot-swap paths so dynamically loaded certs are served immediately
+- Persist loaded certificates on loadCertificate so future rebuilds include them
+
+## 2026-02-15 - 25.3.1 - fix(plugins)
+remove unused dependencies and simplify plugin exports
+
+- Removed multiple dependencies from package.json to reduce dependency footprint: @push.rocks/lik, @push.rocks/smartacme, @push.rocks/smartdelay, @push.rocks/smartfile, @push.rocks/smartnetwork, @push.rocks/smartpromise, @push.rocks/smartrequest, @push.rocks/smartrx, @push.rocks/smartstring, @push.rocks/taskbuffer, @types/minimatch, @types/ws, pretty-ms, ws
+- ts/plugins.ts: stopped importing/exporting node:https and many push.rocks and third-party modules; plugins now only re-export core node modules (without https), tsclass, smartcrypto, smartlog (+ destination-local), smartrust, and minimatch
+- Intended effect: trim surface area and remove unused/optional integrations; patch-level change (no feature/API additions)
+
+## 2026-02-14 - 25.3.0 - feat(smart-proxy)
+add background concurrent certificate provisioning with per-domain timeouts and concurrency control
+
+- Add ISmartProxyOptions settings: certProvisionTimeout (ms) and certProvisionConcurrency (default 4)
+- Run certProvisionFunction as fire-and-forget background tasks (stores promise on start/route-update and awaited on stop)
+- Provision certificates in parallel with a concurrency limit using a new ConcurrencySemaphore utility
+- Introduce per-domain timeout handling (default 300000ms) via withTimeout and surface timeout errors as certificate-failed events
+- Refactor provisioning into provisionSingleDomain to isolate domain handling, ACME fallback preserved
+- Run provisioning outside route update mutex so route updates are not blocked by slow provisioning
+
+## 2026-02-14 - 25.2.2 - fix(smart-proxy)
+start metrics polling before certificate provisioning to avoid blocking metrics collection
+
+- Start metrics polling immediately after Rust engine startup so metrics are available without waiting for certificate provisioning.
+- Run certProvisionFunction after startup because ACME/DNS-01 provisioning can hang or be slow and must not block observability.
+- Code change in ts/proxies/smart-proxy/smart-proxy.ts: metricsAdapter.startPolling() moved to run before provisionCertificatesViaCallback().
+
+## 2026-02-14 - 25.2.1 - fix(smartproxy)
+no changes detected in git diff
+
+- The provided diff contains no file changes; no code or documentation updates to release.
+
+## 2026-02-14 - 25.2.0 - feat(metrics)
+add per-IP and HTTP-request metrics, propagate source IP through proxy paths, and expose new metrics to the TS adapter
+
+- Add per-IP tracking and IpMetrics in MetricsCollector (active/total connections, bytes, throughput).
+- Add HTTP request counters and tracking (total_http_requests, http_requests_per_sec, recent counters and tests).
+- Include throughput history (ThroughputSample serialization, retention and snapshotting) and expose history in snapshots.
+- Propagate source IP through HTTP and passthrough code paths: CountingBody.record_bytes and MetricsCollector methods now accept source_ip; connection_opened/closed calls include source IP.
+- Introduce ForwardMetricsCtx to carry metrics context (collector, route_id, source_ip) into passthrough forwarding routines; update ConnectionGuard to include source_ip.
+- TypeScript adapter (rust-metrics-adapter.ts) updated to return per-IP counts, top IPs, per-IP throughput, throughput history mapping, and HTTP request rates/total where available.
+- Numerous unit tests added for per-IP tracking, HTTP request tracking, throughput history and ThroughputTracker.history behavior.
+
+## 2026-02-13 - 25.1.0 - feat(metrics)
+add real-time throughput sampling and byte-counting metrics
+
+- Add CountingBody wrapper to count HTTP request and response bytes and report them to MetricsCollector.
+- Implement lock-free hot-path byte recording and a cold-path sampling API (sample_all) in MetricsCollector with throughput history and configurable retention (default 3600s).
+- Spawn a background sampling task in RustProxy (configurable sample_interval_ms) and tear it down on stop so throughput trackers are regularly sampled.
+- Instrument passthrough TCP forwarding and socket-relay paths to record per-chunk bytes (lock-free) so long-lived connections contribute to throughput measurements.
+- Wrap HTTP request/response bodies with CountingBody in proxy_service to capture bytes_in/bytes_out and report on body completion; connection_closed handling updated accordingly.
+- Expose recent throughput metrics to the TypeScript adapter (throughputRecentIn/Out) and pass metrics settings from the TS SmartProxy into Rust.
+- Add http-body dependency and update Cargo.toml/Cargo.lock entries for the new body wrapper usage.
+- Add unit tests for MetricsCollector throughput tracking and a new end-to-end throughput test (test.throughput.ts).
+- Update test certificates (assets/certs cert.pem and key.pem) used by TLS tests.
+
+## 2026-02-13 - 25.0.0 - BREAKING CHANGE(certs)
+accept a second eventComms argument in certProvisionFunction, add cert provisioning event types, and emit certificate lifecycle events
+
+- Breaking API change: certProvisionFunction signature changed from (domain: string) => Promise<TSmartProxyCertProvisionObject> to (domain: string, eventComms: ICertProvisionEventComms) => Promise<TSmartProxyCertProvisionObject>. Custom provisioners must accept (or safely ignore) the new second argument.
+- New types added and exported: ICertProvisionEventComms, ICertificateIssuedEvent, ICertificateFailedEvent.
+- smart-proxy now constructs an eventComms channel that allows provisioners to log/warn/error and set expiry date and source for the issued event.
+- Emits 'certificate-issued' (domain, expiryDate, source, isRenewal?) on successful provisioning and 'certificate-failed' (domain, error, source) on failures.
+- Updated public exports to include the new types so they are available to consumers.
+- Removed readme.byte-counting-audit.md (documentation file deleted).
+
+## 2026-02-13 - 24.0.1 - fix(proxy)
+improve proxy robustness: add connect timeouts, graceful shutdown, WebSocket watchdog, and metrics guard
+
+- Add tokio-util CancellationToken to HTTP handlers to support graceful shutdown (stop accepting new requests while letting in-flight requests finish).
+- Introduce configurable upstream connect timeout (DEFAULT_CONNECT_TIMEOUT) and return 504 Gateway Timeout on connect timeouts to avoid hanging connections.
+- Add WebSocket watchdog with inactivity and max-lifetime checks, activity tracking via AtomicU64, and cancellation-driven tunnel aborts.
+- Add ConnectionGuard RAII in passthrough listener to ensure metrics.connection_closed() is called on all exit paths and disarm the guard when handing off to the HTTP proxy.
+- Expose HttpProxyService::with_connect_timeout and wire connection timeout from ConnectionConfig into listeners.
+- Add tokio-util workspace dependency (CancellationToken) and related code changes across rustproxy-http and rustproxy-passthrough.
+
+## 2026-02-13 - 24.0.0 - BREAKING CHANGE(smart-proxy)
+move certificate persistence to an in-memory store and introduce consumer-managed certStore API; add default self-signed fallback cert and change ACME account handling
+
+- Cert persistence removed from Rust side: CertStore is now an in-memory cache (no filesystem reads/writes). Rust no longer persists or loads certs from disk.
+- ACME account credentials are no longer persisted by the library; AcmeClient uses ephemeral accounts only and account persistence APIs were removed.
+- TypeScript API changes: removed certificateStore option and added ISmartProxyCertStore + certStore option for consumer-provided persistence (loadAll, save, optional remove).
+- Default self-signed fallback certificate added (generateDefaultCertificate) and loaded as '*' unless disableDefaultCert is set.
+- SmartProxy now pre-loads certificates from consumer certStore on startup and persists certificates by calling certStore.save() after provisioning.
+- provisionCertificatesViaCallback signature changed to accept preloaded domains (prevents re-provisioning), and ACME fallback behavior adjusted with clearer logging.
+- Rust cert manager methods made infallible for cache-only operations (load_static/store no longer return errors for cache insertions); removed store-backed load_all/remove/base_dir APIs.
+- TCP listener tls_configs concurrency improved: switched to ArcSwap<HashMap<...>> so accept loops see hot-reloads immediately.
+- Removed dependencies related to filesystem cert persistence from the tls crate (serde_json, tempfile) and corresponding Cargo.lock changes and test updates.
+
+## 2026-02-13 - 23.1.6 - fix(smart-proxy)
+disable built-in Rust ACME when a certProvisionFunction is provided and improve certificate provisioning flow
+
+- Pass an optional ACME override into buildRustConfig so Rust ACME can be disabled per-run
+- Disable Rust ACME when certProvisionFunction is configured to avoid provisioning race conditions
+- Normalize routing glob patterns into concrete domain identifiers for certificate provisioning (expand leading-star globs and warn on unsupported patterns)
+- Deduplicate domains during provisioning to avoid repeated attempts
+- When the callback returns 'http01', explicitly trigger Rust ACME for the route via bridge.provisionCertificate and log success/failure
+
+## 2026-02-13 - 23.1.5 - fix(smart-proxy)
+provision certificates for wildcard domains instead of skipping them
+
+- Removed early continue that skipped domains containing '*' in the domain loop
+- Now calls provisionFn for wildcard domains so certificate provisioning can proceed for wildcard hosts
+- Fixes cases where wildcard domains never had certificates requested
+
+## 2026-02-12 - 23.1.4 - fix(tests)
+make tests more robust and bump small dependencies
+
+- Bump dependencies: @push.rocks/smartrust ^1.2.1 and minimatch ^10.2.0
+- Replace hardcoded ports with named constants (ECHO_PORT, PROXY_PORT, PROXY_PORT_1/2) to avoid collisions between tests
+- Add server 'error' handlers and reject listen promises on server errors to prevent silent hangs
+- Reduce test timeouts and intervals (shorter test durations, more frequent pings) to speed up test runs
+- Ensure proxy is stopped between tests and remove forced process.exit; export tap.start() consistently
+- Adjust assertions to match the new shorter ping/response counts
+
+## 2026-02-12 - 23.1.3 - fix(rustproxy)
+install default rustls crypto provider early; detect and skip raw fast-path for HTTP connections and return proper HTTP 502 when no route matches
+
+- Install ring-based rustls crypto provider at startup to prevent panics from instant-acme/hyper-rustls calling ClientConfig::builder() before TLS listeners are initialized
+- Add a non-blocking 10ms peek to detect HTTP traffic in the TCP passthrough fast-path to avoid misrouting HTTP and ensure HTTP proxy handles CORS, errors, and request-level routing
+- Skip the fast-path and fall back to the HTTP proxy when HTTP is detected (with a debug log)
+- When no route matches for detected HTTP connections, send an HTTP 502 Bad Gateway response and close the connection instead of silently dropping it
+
+## 2026-02-11 - 23.1.2 - fix(core)
+use node: scoped builtin imports and add route unit tests
+
+- Replaced bare Node built-in imports (events, fs, http, https, net, path, tls, url, http2, buffer, crypto) with 'node:' specifiers for ESM/bundler compatibility (files updated include ts/plugins.ts, ts/core/models/socket-types.ts, ts/core/utils/enhanced-connection-pool.ts, ts/core/utils/socket-tracker.ts, ts/protocols/common/fragment-handler.ts, ts/protocols/tls/sni/client-hello-parser.ts, ts/protocols/tls/sni/sni-extraction.ts, ts/protocols/websocket/utils.ts, ts/tls/sni/sni-handler.ts).
+- Added new unit tests (test/test.bun.ts and test/test.deno.ts) covering route helpers, validators, matching, merging and cloning to improve test coverage.
+
+## 2026-02-11 - 23.1.1 - fix(rust-proxy)
+increase rust proxy bridge maxPayloadSize to 100 MB and bump dependencies
+
+- Set maxPayloadSize to 100 * 1024 * 1024 (100 MB) in ts/proxies/smart-proxy/rust-proxy-bridge.ts to support large route configs
+- Bump devDependency @types/node from ^25.2.2 to ^25.2.3
+- Bump dependency @push.rocks/smartrust from ^1.1.1 to ^1.2.0
+
 ## 2026-02-10 - 23.1.0 - feat(rust-bridge)
 integrate tsrust to build and locate cross-compiled Rust binaries; refactor rust-proxy bridge to use typed IPC and streamline process handling; add @push.rocks/smartrust and update build/dev dependencies

-# SmartProxy Byte Counting Audit Report
-
-## Executive Summary
-
-After a comprehensive audit of the SmartProxy codebase, I can confirm that **byte counting is implemented correctly** with no instances of double counting. Each byte transferred through the proxy is counted exactly once in each direction.
-
-## Byte Counting Implementation
-
-### 1. Core Tracking Mechanisms
-
-SmartProxy uses two complementary tracking systems:
-
-1. **Connection Records** (`IConnectionRecord`):
-   - `bytesReceived`: Total bytes received from client
-   - `bytesSent`: Total bytes sent to client
-
-2. **MetricsCollector**:
-   - Global throughput tracking via `ThroughputTracker`
-   - Per-connection byte tracking for route/IP metrics
-   - Called via `recordBytes(connectionId, bytesIn, bytesOut)`
-
-### 2. Where Bytes Are Counted
-
-Bytes are counted in only two files:
-
-#### a) `route-connection-handler.ts`
- **Line 351**: TLS alert bytes when no SNI is provided
- **Lines 1286-1301**: Data forwarding callbacks in `setupBidirectionalForwarding()`
-
-#### b) `http-proxy-bridge.ts`  
- **Line 127**: Initial TLS chunk for HttpProxy connections
- **Lines 142-154**: Data forwarding callbacks in `setupBidirectionalForwarding()`
-
-## Connection Flow Analysis
-
-### 1. Direct TCP Connection (No TLS)
-
-```
-Client → SmartProxy → Target Server
-```
-
-1. Connection arrives at `RouteConnectionHandler.handleConnection()`
-2. For non-TLS ports, immediately routes via `routeConnection()`
-3. `setupDirectConnection()` creates target connection
-4. `setupBidirectionalForwarding()` handles all data transfer:
-   - `onClientData`: `bytesReceived += chunk.length` + `recordBytes(chunk.length, 0)`
-   - `onServerData`: `bytesSent += chunk.length` + `recordBytes(0, chunk.length)`
-
-**Result**: ✅ Each byte counted exactly once
-
-### 2. TLS Passthrough Connection
-
-```
-Client (TLS) → SmartProxy → Target Server (TLS)
-```
-
-1. Connection waits for initial data to detect TLS
-2. TLS handshake detected, SNI extracted
-3. Route matched, `setupDirectConnection()` called
-4. Initial chunk stored in `pendingData` (NOT counted yet)
-5. On target connect, `pendingData` written to target (still not counted)
-6. `setupBidirectionalForwarding()` counts ALL bytes including initial chunk
-
-**Result**: ✅ Each byte counted exactly once
-
-### 3. TLS Termination via HttpProxy
-
-```
-Client (TLS) → SmartProxy → HttpProxy (localhost) → Target Server
-```
-
-1. TLS connection detected with `tls.mode = "terminate"`
-2. `forwardToHttpProxy()` called:
-   - Initial chunk: `bytesReceived += chunk.length` + `recordBytes(chunk.length, 0)`
-3. Proxy connection created to HttpProxy on localhost
-4. `setupBidirectionalForwarding()` handles subsequent data
-
-**Result**: ✅ Each byte counted exactly once
-
-### 4. HTTP Connection via HttpProxy
-
-```
-Client (HTTP) → SmartProxy → HttpProxy (localhost) → Target Server
-```
-
-1. Connection on configured HTTP port (`useHttpProxy` ports)
-2. Same flow as TLS termination
-3. All byte counting identical to TLS termination
-
-**Result**: ✅ Each byte counted exactly once
-
-### 5. NFTables Forwarding
-
-```
-Client → [Kernel NFTables] → Target Server
-```
-
-1. Connection detected, route matched with `forwardingEngine: 'nftables'`
-2. Connection marked as `usingNetworkProxy = true`
-3. NO application-level forwarding (kernel handles packet routing)
-4. NO byte counting in application layer
-
-**Result**: ✅ No counting (correct - kernel handles everything)
-
-## Special Cases
-
-### PROXY Protocol
- PROXY protocol headers sent to backend servers are NOT counted in client metrics
- Only actual client data is counted
- **Correct behavior**: Protocol overhead is not client data
-
-### TLS Alerts
- TLS alerts (e.g., for missing SNI) are counted as sent bytes
- **Correct behavior**: Alerts are actual data sent to the client
-
-### Initial Chunks
- **Direct connections**: Stored in `pendingData`, counted when forwarded
- **HttpProxy connections**: Counted immediately upon receipt
- **Both approaches**: Count each byte exactly once
-
-## Verification Methodology
-
-1. **Code Analysis**: Searched for all instances of:
-   - `bytesReceived +=` and `bytesSent +=`
-   - `recordBytes()` calls
-   - Data forwarding implementations
-
-2. **Flow Tracing**: Followed data path for each connection type from entry to exit
-
-3. **Handler Review**: Examined all forwarding handlers to ensure no additional counting
-
-## Findings
-
-### ✅ No Double Counting Detected
-
- Each byte is counted exactly once in the direction it flows
- Connection records and metrics are updated consistently
- No overlapping or duplicate counting logic found
-
-### Areas of Excellence
-
-1. **Centralized Counting**: All byte counting happens in just two files
-2. **Consistent Pattern**: Uses `setupBidirectionalForwarding()` with callbacks
-3. **Clear Separation**: Forwarding handlers don't interfere with proxy metrics
-
-## Recommendations
-
-1. **Debug Logging**: Add optional debug logging to verify byte counts in production:
-   ```typescript
-   if (settings.debugByteCount) {
-     logger.log('debug', `Bytes counted: ${connectionId} +${bytes} (total: ${record.bytesReceived})`);
-   }
-   ```
-
-2. **Unit Tests**: Create specific tests to ensure byte counting accuracy:
-   - Test initial chunk handling
-   - Test PROXY protocol overhead exclusion
-   - Test HttpProxy forwarding accuracy
-
-3. **Protocol Overhead Tracking**: Consider separately tracking:
-   - PROXY protocol headers
-   - TLS handshake bytes
-   - HTTP headers vs body
-
-4. **NFTables Documentation**: Clearly document that NFTables-forwarded connections are not included in application metrics
-
-## Conclusion
-
-SmartProxy's byte counting implementation is **robust and accurate**. The design ensures that each byte is counted exactly once, with clear separation between connection tracking and metrics collection. No remediation is required.

+### 🔀 Protocol-Specific Routing
+
+Restrict routes to specific application-layer protocols. When `protocol` is set, the Rust engine detects the protocol after connection (or after TLS termination) and only matches routes that accept that protocol:
+
+```typescript
+// HTTP-only route (rejects raw TCP connections)
+const httpOnlyRoute: IRouteConfig = {
+  name: 'http-api',
+  match: {
+    ports: 443,
+    domains: 'api.example.com',
+    protocol: 'http',   // Only match HTTP/1.1, HTTP/2, and WebSocket upgrades
+  },
+  action: {
+    type: 'forward',
+    targets: [{ host: 'api-backend', port: 8080 }],
+    tls: { mode: 'terminate', certificate: 'auto' }
+  }
+};
+
+// Raw TCP route (rejects HTTP traffic)
+const tcpOnlyRoute: IRouteConfig = {
+  name: 'database-proxy',
+  match: {
+    ports: 5432,
+    protocol: 'tcp',    // Only match non-HTTP TCP streams
+  },
+  action: {
+    type: 'forward',
+    targets: [{ host: 'db-server', port: 5432 }]
+  }
+};
+```
+
+> **Note:** Omitting `protocol` (the default) matches any protocol. For TLS routes, protocol detection happens *after* TLS termination — during the initial SNI-based route match, `protocol` is not yet known and the route is allowed to match. The protocol restriction is enforced after the proxy peeks at the decrypted data.

+### 💾 Consumer-Managed Certificate Storage
+
+SmartProxy **never writes certificates to disk**. Instead, you own all persistence through the `certStore` interface. This gives you full control — store certs in a database, cloud KMS, encrypted vault, or wherever makes sense for your infrastructure:
+
+```typescript
+const proxy = new SmartProxy({
+  routes: [...],
+
+  certProvisionFunction: async (domain) => myAcme.provision(domain),
+
+  // Your persistence layer — SmartProxy calls these hooks
+  certStore: {
+    // Called once on startup to pre-load persisted certs
+    loadAll: async () => {
+      const certs = await myDb.getAllCerts();
+      return certs.map(c => ({
+        domain: c.domain,
+        publicKey: c.certPem,
+        privateKey: c.keyPem,
+        ca: c.caPem,      // optional
+      }));
+    },
+
+    // Called after each successful cert provision
+    save: async (domain, publicKey, privateKey, ca) => {
+      await myDb.upsertCert({ domain, certPem: publicKey, keyPem: privateKey, caPem: ca });
+    },
+
+    // Optional: called when a cert should be removed
+    remove: async (domain) => {
+      await myDb.deleteCert(domain);
+    },
+  },
+});
+```
+
+**Startup flow:**
+1. Rust engine starts
+2. Default self-signed `*` fallback cert is loaded (unless `disableDefaultCert: true`)
+3. `certStore.loadAll()` is called → all returned certs are loaded into the Rust TLS stack
+4. `certProvisionFunction` runs for any remaining `certificate: 'auto'` routes (skipping domains already loaded from the store)
+5. After each successful provision, `certStore.save()` is called
+
+This means your second startup is instant — no re-provisioning needed for domains that already have valid certs in your store.
