 # 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

+
+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();

+# @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
