+# Changelog
+
+## 2026-02-20 - 7.9.0 - feat(server)
+emit query events with questions, answered status, response time and timestamp
+
+- Added IDnsQueryCompletedEvent interface with questions, answered, responseTimeMs and timestamp fields
+- DnsServer now extends EventEmitter and calls super() in constructor
+- DnsServer emits a 'query' event on incoming dnsQuery from Rust bridge, providing answers and timing
+- Imported IIpcDnsQuestion and used TypeScript 'satisfies' for the emitted event object
+
+## 2026-02-12 - 7.8.1 - fix(server)
+Require Rust bridge for DNS packet processing; remove synchronous TypeScript fallback; change handler API to accept IDnsQuestion and adjust query API
+
+- Breaking API change: handler signature changed from dns-packet.Question to IDnsQuestion — update registered handlers accordingly.
+- Synchronous TypeScript fallback (processDnsRequest/processRawDnsPacket) removed; callers must start the server/bridge and use the async bridge path (processRawDnsPacketAsync) or the new resolveQuery API.
+- processRawDnsPacketAsync now throws if the Rust bridge is not started — call start() before processing packets.
+- Public/test API rename/adjustments: processDnsRequest usages were replaced with resolveQuery and tests updated to use tapbundle_serverside.
+- Dependency changes: moved dns-packet to devDependencies, bumped @push.rocks/smartenv to ^6.0.0, updated @git.zone/* build/test tools and @types/node; removed @push.rocks/smartrequest from client plugin exports.
+- Plugins: dns-packet removed from exported plugins and minimatch kept; ts_client no longer exports smartrequest.
+
+## 2026-02-11 - 7.8.0 - feat(rustdns-client)
+add Rust DNS client binary and TypeScript IPC bridge to enable UDP and DoH resolution, RDATA decoding, and DNSSEC AD/rcode support
+
+- Add new rust crate rustdns-client with IPC management, DoH and UDP resolvers (resolver_doh.rs, resolver_udp.rs) and ipc types
+- Integrate Rust client via a new TypeScript RustDnsClientBridge that spawns rustdns-client and communicates over JSON IPC
+- Expose Rust-based resolution from Smartdns (new strategies: 'udp', 'prefer-udp'; DoH routed through Rust) and add destroy() to clean up the bridge
+- Extend rustdns-protocol with RDATA decoders (A, AAAA, TXT, MX, NS/CNAME/PTR name decoding, SOA, SRV), AD flag detection and rcode() helper
+- Update tests to cover Rust/UDP/DoH paths, DNSSEC AD flag, SOA round-trip and performance assertions
+- Update packaging/readmes and build metadata (npmextra.json, ts_client/readme, ts_server/readme) and Cargo manifests/lock for the new crate
+
+## 2026-02-11 - 7.7.1 - fix(tests)
+prune flaky SOA integration and performance tests that rely on external tools and long-running signing/serialization checks
+
+- Removed 'Test raw SOA serialization' from test/test.soa.debug.ts
+- Removed dig-based 'Test SOA timeout with real dig command' from test/test.soa.timeout.ts
+- Removed 'Check DNSSEC signing performance for SOA' and related serialization/signing performance checks
+- Removed unused imports (plugins, execSync) and testPort constant; minor whitespace/cleanup in stopServer
+
+## 2026-02-11 - 7.7.0 - feat(rust)
+add Rust-based DNS server backend with IPC management and TypeScript bridge
+
+- Adds a new rust/ workspace with crates: rustdns, rustdns-protocol, rustdns-server, rustdns-dnssec (DNS packet parsing/encoding, UDP/HTTPS servers, DNSSEC signing).
+- Implements an IPC management loop and command/event protocol (stdin/stdout) for communication between Rust and TypeScript (ipc_types, management).
+- Introduces DnsResolver and DNSSEC key/signing logic in Rust (keys, signing, keytag), plus UDP and DoH HTTPS server implementations.
+- Adds a TypeScript Rust bridge (ts_server/classes.rustdnsbridge.ts) using @push.rocks/smartrust to spawn and talk to the Rust binary; exposes spawn/start/stop/processPacket/ping APIs.
+- Removes JS-based DNSSEC implementation and updates ts_server plugins to use smartrust; adds tsrust integration and tsrust devDependency and build step in package.json.
+- Documentation and tooling: README updated with Rust backend architecture, .gitignore updated for rust/target, Cargo config for cross-compile linker added.
+
+## 2025-09-12 - 7.6.1 - fix(classes.dnsclient)
+Remove redundant DOH response parsing in getRecords to avoid duplicate processing and clean up client code
+
+- Removed a duplicated/extra iteration that parsed DNS-over-HTTPS (DoH) answers in ts_client/classes.dnsclient.ts.
+- Prevents double-processing or incorrect return behavior from Smartdns.getRecords when using DoH providers.
+- Changes affect the Smartdns client implementation (ts_client/classes.dnsclient.ts).
+
+## 2025-09-12 - 7.6.0 - feat(dnsserver)
+Return multiple matching records, improve DNSSEC RRset signing, add client resolution strategy and localhost handling, update tests
+
+- Server: process all matching handlers for a question so multiple records (NS, A, TXT, etc.) are returned instead of stopping after the first match
+- DNSSEC: sign entire RRsets together (single RRSIG per RRset) and ensure DNSKEY/DS generation and key-tag computation are handled correctly
+- Server: built-in localhost handling (RFC 6761) with an enableLocalhostHandling option and synthetic answers for localhost/127.0.0.1 reverse lookups
+- Server: improved SOA generation (primary nameserver handling), name serialization (trim trailing dot), and safer start/stop behavior
+- Client: added resolution strategy options (doh | system | prefer-system), allowDohFallback and per-query timeout support; improved DoH and system lookup handling (proper TXT quoting and name trimming)
+- Tests: updated expectations and test descriptions to reflect correct multi-record behavior and other fixes
+
+## 2025-09-12 - 7.5.1 - fix(dependencies)
+Bump dependency versions and add pnpm workspace onlyBuiltDependencies
+
+- Bumped @push.rocks/smartenv from ^5.0.5 to ^5.0.13

+
+## 2025-06-01 - 7.5.0 - feat(dnssec)
+Add MX record DNSSEC support for proper serialization and authentication of mail exchange records
+
+- Serialize MX records by combining a 16-bit preference with the exchange domain name
+- Enable DNSSEC signature generation for MX records to authenticate mail exchange data
+- Update documentation to include the new MX record DNSSEC support in version v7.4.8
+
+## 2025-05-30 - 7.4.7 - fix(dnsserver)
+Update documentation to clarify the primaryNameserver option and SOA record behavior in the DNS server. The changes detail how the primaryNameserver configuration customizes the SOA mname, ensures proper DNSSEC signing for RRsets, and updates the configuration interface examples.
+
+- Documented the primaryNameserver option in IDnsServerOptions with default behavior (ns1.{dnssecZone})
+- Clarified SOA record generation including mname, rname, serial, and TTL fields
+- Updated readme examples to demonstrate binding interfaces and proper DNS server configuration
+

+
+- Fixed DNSSEC to sign entire RRsets together instead of individual records (one RRSIG per record type)
+- Fixed SOA record serialization by implementing proper wire format encoding in serializeRData method
+- Fixed RRSIG generation by using correct field names (signersName) and types (string typeCovered)
+- Added configurable primary nameserver via primaryNameserver option in IDnsServerOptions
+- Enhanced test coverage with comprehensive SOA and DNSSEC test scenarios
+
+## 2025-05-30 - 7.4.2 - fix(dnsserver)
+Enable multiple DNS record support by removing the premature break in processDnsRequest. Now the DNS server aggregates answers from all matching handlers for NS, A, and TXT records, and improves NS record serialization for DNSSEC.
+
+- Removed the break statement in processDnsRequest to allow all matching handlers to contribute responses.
+- Updated NS record serialization to properly handle domain names in DNSSEC context.
+- Enhanced tests for round-robin A records and multiple TXT records scenarios.
+
+## 2025-05-28 - 7.4.1 - fix(test/server)
+Fix force cleanup in DNS server tests by casting server properties before closing sockets
+
+- Cast server to any to safely invoke close() on httpsServer and udpServer in test cleanup

+# smartdns - Implementation Hints
+
+## Architecture Overview
+
+The smartdns library is structured into three main modules:
+
+1. **Client Module** (`ts_client/`) - DNS client functionality
+2. **Server Module** (`ts_server/`) - DNS server with Rust backend
+3. **Main Module** (`ts/`) - Re-exports both client and server
+4. **Rust Module** (`rust/`) - High-performance DNS server binary
+
+## Rust Backend Architecture (v8.0+)
+
+The DNS server's network I/O, packet parsing/encoding, and DNSSEC signing run in Rust.
+TypeScript retains handler registration, ACME orchestration, and the public API.
+
+### Rust Crate Structure
+- `rustdns` - Main binary with IPC management loop (`--management` flag)
+- `rustdns-protocol` - DNS wire format parsing/encoding, record types
+- `rustdns-server` - Async UDP + HTTPS DoH servers (tokio, hyper, rustls)
+- `rustdns-dnssec` - ECDSA P-256 / ED25519 key generation and RRset signing
+
+### IPC Flow
+```
+DNS Query -> Rust (UDP/HTTPS) -> Parse packet
+  -> Try local resolution (localhost, DNSKEY)
+  -> If handler needed: emit "dnsQuery" event to TypeScript
+  -> TypeScript runs minimatch handlers, sends "dnsQueryResult" back
+  -> Rust builds response, signs DNSSEC if requested, sends packet
+```
+
+### Key Files
+- `ts_server/classes.rustdnsbridge.ts` - TypeScript IPC bridge wrapping smartrust.RustBridge
+- `ts_server/classes.dnsserver.ts` - DnsServer class (public API, delegates to Rust bridge)
+- `rust/crates/rustdns/src/management.rs` - IPC management loop
+- `rust/crates/rustdns/src/resolver.rs` - DNS resolver with callback support
+
+## Client Module (Smartdns class)
+
+### Key Features:
+- DNS record queries (A, AAAA, TXT, MX, etc.)
+- Support for multiple DNS providers (Google DNS, Cloudflare)
+- DNS propagation checking with retry logic
+- DNSSEC verification support
+- Both HTTP-based (DoH) and Node.js DNS resolver fallback
+
+### Implementation Details:
+- Uses Cloudflare's DNS-over-HTTPS API as primary resolver
+- Falls back to Node.js DNS module for local resolution
+- Implements automatic retry logic with configurable intervals
+- Properly handles quoted TXT records and trailing dots in domain names
+
+### Key Methods:
+- `getRecordsA()`, `getRecordsAAAA()`, `getRecordsTxt()` - Type-specific queries
+- `getRecords()` - Generic record query with retry support
+- `checkUntilAvailable()` - DNS propagation verification
+- `getNameServers()` - NS record lookup
+- `makeNodeProcessUseDnsProvider()` - Configure system DNS resolver
+
+## Server Module (DnsServer class)
+
+### Key Features:
+- Full DNS server supporting UDP and HTTPS (DoH) protocols
+- DNSSEC implementation with multiple algorithms
+- Dynamic handler registration for custom responses
+- Let's Encrypt integration for automatic SSL certificates
+- Wildcard domain support with pattern matching
+
+### DNSSEC Implementation:
+- Supports ECDSA (algorithm 13), ED25519 (algorithm 15), and RSA (algorithm 8)
+- Automatic DNSKEY and DS record generation
+- RRSIG signature generation for authenticated responses
+- Key tag computation following RFC 4034
+
+### Let's Encrypt Integration:
+- Automatic SSL certificate retrieval using DNS-01 challenges
+- Dynamic TXT record handler registration for ACME validation
+- Certificate renewal and HTTPS server restart capability
+- Domain authorization filtering for security
+
+### Handler System:
+- Pattern-based domain matching using minimatch
+- Support for all common record types
+- **Multiple Handler Support**: As of v7.4.2+, multiple handlers can contribute records of the same type
+- Handler chaining for complex scenarios
+- Automatic SOA response for unhandled queries
+
+### Multiple Records Support (v7.4.2+):
+- Server now processes ALL matching handlers for a query (previously stopped after first match)
+- Enables proper multi-NS record support for domain registration
+- Supports round-robin DNS with multiple A/AAAA records
+- Allows multiple TXT records (SPF, DKIM, domain verification)
+- Each handler contributes its record to the response
+
+## Key Dependencies
+
+- `dns-packet`: DNS packet encoding/decoding (wire format, used by TS fallback path)
+- `acme-client`: Let's Encrypt certificate automation
+- `minimatch`: Glob pattern matching for domains
+- `@push.rocks/smartrust`: TypeScript-to-Rust IPC bridge
+- `@tsclass/tsclass`: Type definitions for DNS records
+
+## Testing Insights
+
+The test suite demonstrates:
+- Mock ACME client for testing Let's Encrypt integration
+- Self-signed certificate generation for HTTPS testing
+- Unique port allocation to avoid conflicts
+- Proper server cleanup between tests
+- Both UDP and HTTPS query validation
+
+## Common Patterns
+
+1. **DNS Record Types**: Internally mapped to numeric values (A=1, AAAA=28, etc.)
+2. **Error Handling**: Graceful fallback and retry mechanisms
+3. **DNSSEC Workflow**: Zone → Key Generation → Signing → Verification
+4. **Certificate Flow**: Domain validation → Challenge setup → Verification → Certificate retrieval
+
+## Performance Considerations
+
+- Client implements caching via DNS-over-HTTPS responses
+- Server can handle concurrent UDP and HTTPS requests
+- DNSSEC signing is performed on-demand for efficiency
+- Handler registration is O(n) lookup but uses pattern caching
+
+## Security Notes
+
+- DNSSEC provides authentication but not encryption
+- DoH (DNS-over-HTTPS) provides both privacy and integrity
+- Let's Encrypt integration requires proper domain authorization
+- Handler patterns should be carefully designed to avoid open resolvers
+
+## Recent Improvements (v7.4.3)
+
+1. **DNSSEC RRset Signing**: Fixed to properly sign entire RRsets together instead of individual records
+2. **SOA Record Serialization**: Implemented proper SOA record encoding for DNSSEC compatibility
+3. **Configurable Primary Nameserver**: Added `primaryNameserver` option to customize SOA mname field
+
+## Recent Improvements (v7.4.8)
+
+1. **MX Record DNSSEC Support**: Implemented MX record serialization for DNSSEC signing
+   - MX records consist of a 16-bit preference value followed by the exchange domain name
+   - Properly serializes both components for DNSSEC signature generation
+   - Enables mail exchange records to be authenticated with DNSSEC
+
+## Known Limitations
+
+1. **Handler Deduplication**: If the same handler is registered multiple times, it will contribute duplicate records (this may be desired behavior for some use cases)

+# @push.rocks/smartdns
+
+A TypeScript-first DNS toolkit powered by high-performance Rust binaries — covering everything from simple record lookups to running a full authoritative DNS server with DNSSEC, DNS-over-HTTPS, and automatic Let's Encrypt certificates.
+
+## Issue Reporting and Security
+
+For reporting bugs, issues, or security vulnerabilities, please visit [community.foss.global/](https://community.foss.global/). This is the central community hub for all issue reporting. Developers who sign and comply with our contribution agreement and go through identification can also get a [code.foss.global/](https://code.foss.global/) account to submit Pull Requests directly.
+
+## Install
+
+```bash
+pnpm install @push.rocks/smartdns
+```
+
+## Architecture at a Glance 🏗️
+
+smartdns ships as **three entry points** that you can import independently:
+
+| Entry point | What it does |
+|---|---|
+| `@push.rocks/smartdns/client` | DNS resolution & record queries (UDP, DoH, system resolver) |
+| `@push.rocks/smartdns/server` | Full DNS server — UDP, DoH, DNSSEC, ACME |
+| `@push.rocks/smartdns` | Convenience re-export of both modules |
+
+Both the **client** and the **server** delegate performance-critical work to compiled **Rust binaries** that ship with the package:
+
+- **`rustdns`** — The server binary: network I/O, packet parsing, DNSSEC signing
+- **`rustdns-client`** — The client binary: UDP wire-format queries, RFC 8484 DoH resolution
+
+TypeScript retains the public API, handler registration, ACME orchestration, and strategy routing. Communication between TypeScript and Rust happens over stdin/stdout JSON IPC via [`@push.rocks/smartrust`](https://code.foss.global/push.rocks/smartrust).

+
+## Usage
+
+### Quick Start
+
+```typescript
+// DNS client — resolve records
+import { Smartdns } from '@push.rocks/smartdns/client';
+
+const dns = new Smartdns({});
+const records = await dns.getRecordsA('example.com');
+console.log(records);
+
+// DNS server — serve records
+import { DnsServer } from '@push.rocks/smartdns/server';
+
+const server = new DnsServer({
+  udpPort: 5333,
+  httpsPort: 8443,
+  httpsKey: '...pem...',
+  httpsCert: '...pem...',
+  dnssecZone: 'example.com',
+});
+
+server.registerHandler('*.example.com', ['A'], (question) => ({
+  name: question.name,
+  type: 'A',
+  class: 'IN',
+  ttl: 300,
+  data: '192.168.1.100',
+}));
+
+await server.start();
+```
+
+Or import from the unified entry point:
+
+```typescript
+import { dnsClientMod, dnsServerMod } from '@push.rocks/smartdns';
+
+const client = new dnsClientMod.Smartdns({});
+const server = new dnsServerMod.DnsServer({ /* ... */ });
+```
+
+---
+
+## 🔍 DNS Client
+
+The `Smartdns` class resolves DNS records using a configurable strategy that combines the system resolver, raw UDP queries, and DNS-over-HTTPS — all backed by a Rust binary for the wire-format transports.
+
+### Constructor Options
+
+```typescript
+interface ISmartDnsConstructorOptions {
+  strategy?: 'doh' | 'udp' | 'system' | 'prefer-system' | 'prefer-udp'; // default: 'prefer-system'
+  allowDohFallback?: boolean; // fallback to DoH when system fails (default: true)
+  timeoutMs?: number; // per-query timeout in milliseconds
+}
+```
+
+### Resolution Strategies
+
+| Strategy | Behavior |
+|---|---|
+| `prefer-system` | 🏠 Try the OS resolver first, fall back to Rust DoH. Honors `/etc/hosts`. |
+| `system` | 🏠 Use only the Node.js system resolver. No Rust binary needed. |
+| `doh` | 🌐 Use only DNS-over-HTTPS (RFC 8484 wire format via Cloudflare). Rust-powered. |
+| `udp` | ⚡ Use only raw UDP queries to upstream resolver (Cloudflare 1.1.1.1). Rust-powered. |
+| `prefer-udp` | ⚡ Try Rust UDP first, fall back to Rust DoH if UDP fails. |
+
+The Rust binary (`rustdns-client`) is spawned **lazily** — only on the first query that needs it. This means `system`-only usage incurs zero Rust overhead.
+
+### Querying Records
+
+```typescript
+const dns = new Smartdns({ strategy: 'prefer-udp' });
+
+// Type-specific helpers
+const aRecords    = await dns.getRecordsA('example.com');
+const aaaaRecords = await dns.getRecordsAAAA('example.com');
+const txtRecords  = await dns.getRecordsTxt('example.com');
+
+// Generic query — supports A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV
+const mxRecords = await dns.getRecords('example.com', 'MX');
+
+// Nameserver lookup
+const nameservers = await dns.getNameServers('example.com');
+```
+
+Every query returns an array of `IDnsRecord`:
+
+```typescript
+interface IDnsRecord {
+  name: string;
+  type: string;          // 'A', 'AAAA', 'TXT', 'MX', etc.
+  dnsSecEnabled: boolean; // true if upstream AD flag was set
+  value: string;
+}
+```
+
+### DNSSEC Detection 🔐
+
+When using `doh`, `udp`, or `prefer-udp` strategies, the Rust binary sends queries with the EDNS0 DO (DNSSEC OK) bit set and reports the AD (Authenticated Data) flag from the upstream response:
+
+```typescript
+const dns = new Smartdns({ strategy: 'udp' });
+const records = await dns.getRecordsA('cloudflare.com');
+console.log(records[0].dnsSecEnabled); // true — upstream validated DNSSEC
+```
+
+### Checking DNS Propagation
+
+Wait for a specific record to appear — essential after making DNS changes:
+
+```typescript
+const propagated = await dns.checkUntilAvailable(
+  'example.com',
+  'TXT',
+  'verification=abc123',
+  50,   // max check cycles (default: 50)
+  500   // interval in ms (default: 500)
+);
+
+if (propagated) {
+  console.log('Record is live!');
+}
+```
+
+The method alternates between system resolver and the configured strategy on each cycle for maximum coverage.
+
+### Configuring the System DNS Provider
+
+Override the global Node.js DNS resolver for all subsequent lookups:
+
+```typescript
+import { makeNodeProcessUseDnsProvider } from '@push.rocks/smartdns/client';
+
+makeNodeProcessUseDnsProvider('cloudflare'); // 1.1.1.1 / 1.0.0.1
+makeNodeProcessUseDnsProvider('google');     // 8.8.8.8 / 8.8.4.4
+```
+
+### Cleanup
+
+When you're done with a `Smartdns` instance (especially one using Rust strategies), call `destroy()` to kill the Rust child process:
+
+```typescript
+const dns = new Smartdns({ strategy: 'udp' });
+// ... do queries ...
+dns.destroy(); // kills rustdns-client process
+```
+
+---
+
+## 🖥️ DNS Server
+
+The `DnsServer` class runs a production-capable authoritative DNS server backed by a Rust binary. It supports standard UDP DNS (port 53), DNS-over-HTTPS, DNSSEC signing, and automated Let's Encrypt certificates.
+
+### Server Options
+
+```typescript
+interface IDnsServerOptions {
+  udpPort: number;               // Port for UDP DNS queries
+  httpsPort: number;             // Port for DNS-over-HTTPS
+  httpsKey: string;              // PEM private key (path or content)
+  httpsCert: string;             // PEM certificate (path or content)
+  dnssecZone: string;            // Zone for DNSSEC signing
+  primaryNameserver?: string;    // SOA mname field (default: 'ns1.{dnssecZone}')
+  udpBindInterface?: string;     // IP to bind UDP (default: '0.0.0.0')
+  httpsBindInterface?: string;   // IP to bind HTTPS (default: '0.0.0.0')
+  manualUdpMode?: boolean;       // Don't auto-bind UDP socket
+  manualHttpsMode?: boolean;     // Don't auto-bind HTTPS server
+  enableLocalhostHandling?: boolean; // RFC 6761 localhost (default: true)
+}
+```
+
+### Basic Server
+
+```typescript
+import { DnsServer } from '@push.rocks/smartdns/server';
+
+const server = new DnsServer({
+  udpPort: 5333,
+  httpsPort: 8443,
+  httpsKey: '...pem...',
+  httpsCert: '...pem...',
+  dnssecZone: 'example.com',
+});
+
+// Register handlers
+server.registerHandler('example.com', ['A'], (question) => ({
+  name: question.name,
+  type: 'A',
+  class: 'IN',
+  ttl: 300,
+  data: '93.184.215.14',
+}));
+
+server.registerHandler('example.com', ['TXT'], (question) => ({
+  name: question.name,
+  type: 'TXT',
+  class: 'IN',
+  ttl: 300,
+  data: 'v=spf1 include:_spf.example.com ~all',
+}));
+
+await server.start();
+// DNS Server started (UDP: 0.0.0.0:5333, HTTPS: 0.0.0.0:8443)
+```
+
+### Handler System 🎯
+
+Handlers use **glob patterns** (via `minimatch`) to match incoming query names. Multiple handlers can contribute records to the same response.
+
+```typescript
+// Exact domain
+server.registerHandler('example.com', ['A'], handler);
+
+// All subdomains
+server.registerHandler('*.example.com', ['A'], handler);
+
+// Specific pattern
+server.registerHandler('db-*.internal.example.com', ['A'], (question) => {
+  const id = question.name.match(/db-(\d+)/)?.[1];
+  return {
+    name: question.name,
+    type: 'A',
+    class: 'IN',
+    ttl: 60,
+    data: `10.0.1.${id}`,
+  };
+});
+
+// Catch-all
+server.registerHandler('*', ['A'], (question) => ({
+  name: question.name,
+  type: 'A',
+  class: 'IN',
+  ttl: 300,
+  data: '127.0.0.1',
+}));
+
+// Multiple record types
+server.registerHandler('example.com', ['MX'], (question) => ({
+  name: question.name,
+  type: 'MX',
+  class: 'IN',
+  ttl: 300,
+  data: { preference: 10, exchange: 'mail.example.com' },
+}));
+
+// Unregister a handler
+server.unregisterHandler('example.com', ['A']);
+```
+
+When no handler matches, the server automatically returns an **SOA record** for the zone.
+
+### DNSSEC ✅
+
+DNSSEC is enabled automatically when you set the `dnssecZone` option. The Rust backend handles:
+
+- **Key generation** — ECDSA P-256 (algorithm 13) by default
+- **DNSKEY / DS record** generation
+- **RRSIG signing** for all responses
+- **NSEC records** for authenticated denial of existence
+
+```typescript
+const server = new DnsServer({
+  udpPort: 53,
+  httpsPort: 443,
+  httpsKey: '...',
+  httpsCert: '...',
+  dnssecZone: 'secure.example.com',
+});
+
+// Just register handlers as usual — signing is automatic
+server.registerHandler('secure.example.com', ['A'], (q) => ({
+  name: q.name,
+  type: 'A',
+  class: 'IN',
+  ttl: 300,
+  data: '10.0.0.1',
+}));
+
+await server.start();
+```
+
+Supported algorithms: **ECDSAP256SHA256** (13), **ED25519** (15), **RSASHA256** (8).
+
+### SOA Records
+
+The server auto-generates SOA records for zones when no specific handler matches. Customize the primary nameserver:
+
+```typescript
+const server = new DnsServer({
+  // ...
+  dnssecZone: 'example.com',
+  primaryNameserver: 'ns1.example.com', // defaults to 'ns1.{dnssecZone}'
+});
+
+// Generated SOA includes:
+// mname:   ns1.example.com
+// rname:   hostmaster.example.com
+// serial:  Unix timestamp
+// refresh: 3600, retry: 600, expire: 604800, minimum: 86400
+```
+
+### Let's Encrypt Integration 🔒
+
+Built-in ACME DNS-01 challenge support for automatic SSL certificates:
+
+```typescript
+const server = new DnsServer({
+  udpPort: 53,
+  httpsPort: 443,
+  httpsKey: '/path/to/key.pem',
+  httpsCert: '/path/to/cert.pem',
+  dnssecZone: 'example.com',
+});
+
+await server.start();
+
+const result = await server.retrieveSslCertificate(
+  ['example.com', 'www.example.com'],
+  {
+    email: 'admin@example.com',
+    staging: false,
+    certDir: './certs',
+  }
+);
+
+if (result.success) {
+  console.log('Certificate installed!');
+  // The server automatically:
+  // 1. Registers temporary _acme-challenge TXT handlers
+  // 2. Completes DNS-01 validation
+  // 3. Updates the HTTPS server with the new cert
+  // 4. Cleans up challenge handlers
+}
+```
+
+### Interface Binding
+
+Restrict the server to specific network interfaces:
+
+```typescript
+// Localhost only — great for development
+const server = new DnsServer({
+  // ...
+  udpBindInterface: '127.0.0.1',
+  httpsBindInterface: '127.0.0.1',
+});
+
+// Different interfaces per protocol
+const server = new DnsServer({
+  // ...
+  udpBindInterface: '192.168.1.100',
+  httpsBindInterface: '10.0.0.50',
+});
+```
+
+### Manual Socket Handling 🔧
+
+For clustering, load balancing, or custom transports, take control of socket management:
+
+```typescript
+import { DnsServer } from '@push.rocks/smartdns/server';
+import * as dgram from 'dgram';
+
+// Manual UDP mode — you control the socket
+const server = new DnsServer({
+  // ...
+  manualUdpMode: true,
+});
+
+await server.start(); // HTTPS auto-binds, UDP does not
+
+const socket = dgram.createSocket('udp4');
+socket.on('message', (msg, rinfo) => {
+  server.handleUdpMessage(msg, rinfo, (response, responseRinfo) => {
+    socket.send(response, responseRinfo.port, responseRinfo.address);
+  });
+});
+socket.bind(5353);
+```
+
+Full manual mode (both protocols):
+
+```typescript
+const server = new DnsServer({
+  // ...
+  manualUdpMode: true,
+  manualHttpsMode: true,
+});
+
+await server.start(); // Neither protocol binds automatically
+```
+
+Process individual DNS packets directly:
+
+```typescript
+// Synchronous (TypeScript fallback)
+const response = server.processRawDnsPacket(packetBuffer);
+
+// Asynchronous (via Rust bridge — includes DNSSEC signing)
+const response = await server.processRawDnsPacketAsync(packetBuffer);
+```
+
+#### Load Balancing Example
+
+```typescript
+import * as dgram from 'dgram';
+import * as os from 'os';
+
+const numCPUs = os.cpus().length;
+
+for (let i = 0; i < numCPUs; i++) {
+  const socket = dgram.createSocket({ type: 'udp4', reuseAddr: true });
+
+  socket.on('message', (msg, rinfo) => {
+    server.handleUdpMessage(msg, rinfo, (response, rinfo) => {
+      socket.send(response, rinfo.port, rinfo.address);
+    });
+  });
+
+  socket.bind(53);
+}
+```
+
+### Stopping the Server
+
+```typescript
+await server.stop();
+```
+
+This gracefully shuts down the Rust process and releases all bound sockets.

+  const dns = new Smartdns({ strategy: 'udp' });
+  const records = await dns.getRecordsA('google.com');
+  expect(records).toBeArray();
+  expect(records[0]).toHaveProperty('type', 'A');
+  expect(records[0]).toHaveProperty('value');
+  dns.destroy();
+});
+
+tap.test('detect DNSSEC via DoH', async () => {
+  const dns = new Smartdns({ strategy: 'doh' });
+  const records = await dns.getRecordsA('cloudflare.com');
+  expect(records[0].dnsSecEnabled).toBeTrue();
+  dns.destroy();
+});
+
+export default tap.start();

+# @push.rocks/smartdns
+
+Unified entry point that re-exports both the DNS client and DNS server modules.
+
+## Import
+
+```typescript
+import { dnsClientMod, dnsServerMod } from '@push.rocks/smartdns';
+```
+
+## Modules
+
+| Module | Description |
+|---|---|
+| `dnsClientMod` | DNS resolution — system, UDP, DoH strategies via `Smartdns` class |
+| `dnsServerMod` | Authoritative DNS server — UDP, HTTPS, DNSSEC, ACME via `DnsServer` class |
+
+## Usage
+
+```typescript
+import { dnsClientMod, dnsServerMod } from '@push.rocks/smartdns';
+
+// Client
+const client = new dnsClientMod.Smartdns({ strategy: 'prefer-udp' });
+const records = await client.getRecordsA('example.com');
+client.destroy();
+
+// Server
+const server = new dnsServerMod.DnsServer({
+  udpPort: 5333,
+  httpsPort: 8443,
+  httpsKey: '...',
+  httpsCert: '...',
+  dnssecZone: 'example.com',
+});
+server.registerHandler('example.com', ['A'], (q) => ({
+  name: q.name, type: 'A', class: 'IN', ttl: 300, data: '93.184.215.14',
+}));
+await server.start();
+```
+
+For direct imports, use the sub-module paths:
+
+```typescript
+import { Smartdns } from '@push.rocks/smartdns/client';
+import { DnsServer } from '@push.rocks/smartdns/server';
+```

+# @push.rocks/smartdns/client
+
+DNS client module for `@push.rocks/smartdns` — provides DNS record resolution via system resolver, raw UDP wire-format queries, and DNS-over-HTTPS (RFC 8484), with UDP and DoH powered by a Rust binary for performance.
+
+## Import
+
+```typescript
+import { Smartdns, makeNodeProcessUseDnsProvider } from '@push.rocks/smartdns/client';
+```
+
+## Architecture
+
+The client routes queries through one of three backends depending on the configured strategy:
+
+- **System** — Uses Node.js `dns` module (`dns.lookup` / `dns.resolveTxt`). Honors `/etc/hosts`. No external binary.
+- **UDP** — Sends raw DNS wire-format queries to upstream resolvers (default: Cloudflare 1.1.1.1) via the `rustdns-client` Rust binary over IPC.
+- **DoH** — Sends RFC 8484 wire-format POST requests to a DoH endpoint (default: `https://cloudflare-dns.com/dns-query`) via the same Rust binary.
+
+The Rust binary is spawned **lazily** — only when the first UDP or DoH query is made. The binary stays alive for connection pooling (DoH) and is killed via `destroy()`.
+
+## Classes & Functions
+
+### `Smartdns`
+
+The main DNS client class. Supports five resolution strategies:
+
+| Strategy | Behavior |
+|---|---|
+| `prefer-system` | Try OS resolver first, fall back to Rust DoH |
+| `system` | Use only Node.js system resolver |
+| `doh` | Use only Rust DoH (RFC 8484 wire format) |
+| `udp` | Use only Rust UDP to upstream resolver |
+| `prefer-udp` | Try Rust UDP first, fall back to Rust DoH |
+
+```typescript
+const dns = new Smartdns({
+  strategy: 'prefer-udp',
+  allowDohFallback: true,
+  timeoutMs: 5000,
+});
+```
+
+#### Key Methods
+
+| Method | Description |
+|---|---|
+| `getRecordsA(domain)` | Resolve A records (IPv4) |
+| `getRecordsAAAA(domain)` | Resolve AAAA records (IPv6) |
+| `getRecordsTxt(domain)` | Resolve TXT records |
+| `getRecords(domain, type, retries?)` | Generic query — supports A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV |
+| `getNameServers(domain)` | Resolve NS records |
+| `checkUntilAvailable(domain, type, value, cycles?, interval?)` | Poll until a record propagates |
+| `destroy()` | Kill the Rust client binary and free resources |
+
+All query methods return `IDnsRecord[]`:
+
+```typescript
+interface IDnsRecord {
+  name: string;
+  type: string;
+  dnsSecEnabled: boolean; // true if upstream AD flag was set
+  value: string;
+}
+```
+
+### `RustDnsClientBridge`
+
+Low-level IPC bridge to the `rustdns-client` binary. Used internally by `Smartdns` — typically not imported directly. Provides:
+
+- `ensureSpawned()` — lazy spawn of the Rust binary
+- `resolve(name, type, protocol, ...)` — send a resolve command via IPC
+- `ping()` — health check
+- `kill()` — terminate the binary
+
+### `makeNodeProcessUseDnsProvider(provider)`
+
+Configures the global Node.js DNS resolver to use a specific provider:
+
+```typescript
+makeNodeProcessUseDnsProvider('cloudflare'); // 1.1.1.1
+makeNodeProcessUseDnsProvider('google');     // 8.8.8.8
+```
+
+## Supported Record Types
+
+A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV
+
+## Dependencies
+
+- `@push.rocks/smartrust` — TypeScript-to-Rust IPC bridge
+- `@push.rocks/smartrequest` — HTTP client (used by legacy paths)
+- `@push.rocks/smartdelay` — delay utility for retry logic
+- `@push.rocks/smartpromise` — deferred promise helper
+- `@tsclass/tsclass` — DNS record type definitions

+# @push.rocks/smartdns/server
+
+DNS server module for `@push.rocks/smartdns` — a full-featured authoritative DNS server powered by a Rust backend with DNSSEC, DNS-over-HTTPS, and Let's Encrypt integration.
+
+## Import
+
+```typescript
+import { DnsServer } from '@push.rocks/smartdns/server';
+```
+
+## Architecture
+
+The server delegates network I/O, DNS packet parsing/encoding, and DNSSEC signing to a compiled **Rust binary** (`rustdns`). TypeScript retains the public API, handler registration, and ACME certificate orchestration.
+
+Communication happens via JSON-over-stdin/stdout IPC using `@push.rocks/smartrust`'s `RustBridge`. DNS queries that need handler resolution are forwarded from Rust to TypeScript with correlation IDs, then results are sent back for response assembly and DNSSEC signing.
+
+### Rust Crate Structure
+
+| Crate | Purpose |
+|---|---|
+| `rustdns` | Main binary with IPC management loop |
+| `rustdns-protocol` | DNS wire format parsing/encoding, RDATA encode/decode |
+| `rustdns-server` | Async UDP + HTTPS servers (tokio, hyper, rustls) |
+| `rustdns-dnssec` | ECDSA/ED25519 key generation and RRset signing |
+
+## Classes
+
+### `DnsServer`
+
+The primary class. Manages handler registration, server lifecycle, and certificate retrieval.
+
+```typescript
+const server = new DnsServer({
+  udpPort: 53,
+  httpsPort: 443,
+  httpsKey: '...pem...',
+  httpsCert: '...pem...',
+  dnssecZone: 'example.com',
+  primaryNameserver: 'ns1.example.com',
+});
+```
+
+#### Options
+
+| Option | Type | Default | Description |
+|---|---|---|---|
+| `udpPort` | `number` | — | UDP DNS port |
+| `httpsPort` | `number` | — | HTTPS DoH port |
+| `httpsKey` | `string` | — | TLS private key (PEM) |
+| `httpsCert` | `string` | — | TLS certificate (PEM) |
+| `dnssecZone` | `string` | — | Zone to enable DNSSEC for |
+| `primaryNameserver` | `string` | `ns1.{zone}` | SOA mname field |
+| `udpBindInterface` | `string` | `0.0.0.0` | IP to bind UDP |
+| `httpsBindInterface` | `string` | `0.0.0.0` | IP to bind HTTPS |
+| `manualUdpMode` | `boolean` | `false` | Don't auto-bind UDP |
+| `manualHttpsMode` | `boolean` | `false` | Don't auto-bind HTTPS |
+| `enableLocalhostHandling` | `boolean` | `true` | Handle RFC 6761 localhost |
+
+#### Key Methods
+
+| Method | Description |
+|---|---|
+| `start()` | Spawn Rust binary and start listening |
+| `stop()` | Gracefully shut down |
+| `registerHandler(pattern, types, fn)` | Add a DNS handler (glob patterns via minimatch) |
+| `unregisterHandler(pattern, types)` | Remove a handler |
+| `handleUdpMessage(msg, rinfo, cb)` | Process a UDP message manually |
+| `processRawDnsPacket(buf)` | Sync packet processing (TS fallback) |
+| `processRawDnsPacketAsync(buf)` | Async packet processing (Rust bridge, includes DNSSEC) |
+| `retrieveSslCertificate(domains, opts)` | ACME DNS-01 certificate retrieval |
+| `filterAuthorizedDomains(domains)` | Filter domains the server is authoritative for |
+
+### `RustDnsBridge`
+
+Low-level IPC bridge to the `rustdns` binary. Used internally by `DnsServer` — typically not imported directly.
+
+Emits events: `dnsQuery`, `started`, `stopped`, `error`.
+
+## Handler System
+
+Handlers use **glob patterns** (via `minimatch`) for domain matching. Multiple handlers can contribute records to a single response.
+
+```typescript
+server.registerHandler('*.example.com', ['A'], (question) => ({
+  name: question.name,
+  type: 'A',
+  class: 'IN',
+  ttl: 300,
+  data: '10.0.0.1',
+}));
+```
+
+When no handler matches, the server returns an automatic **SOA record** for the zone.
+
+## DNSSEC
+
+Enabled automatically with the `dnssecZone` option. Supports:
+
+- **ECDSAP256SHA256** (13) — default
+- **ED25519** (15)
+- **RSASHA256** (8)
+
+Key generation, DNSKEY/RRSIG/NSEC record creation is fully handled by the Rust backend.
+
+## Dependencies
+
+- `@push.rocks/smartrust` — TypeScript-to-Rust IPC bridge
+- `dns-packet` — DNS wire format codec (used for TS fallback path)
+- `minimatch` — glob pattern matching for handlers
+- `acme-client` — Let's Encrypt ACME protocol
