 # Changelog
 ## 2026-02-13 - 5.4.1 - fix(network,dcrouter)
 Always register SmartProxy certificate event handlers and include total bytes + improved connection metrics in network stats/UI
 - Always register SmartProxy 'certificate-issued', 'certificate-renewed', and 'certificate-failed' handlers (previously only registered when acmeConfig was present) so certificate events are processed regardless of provisioning path.
 - Add totalBytes (in/out) to network stats and propagate it through ts_interfaces and app state so total data transferred is available to the UI.
 - Combine metricsManager.getNetworkStats with collectServerStats to compute activeConnections and adjust connectionDetails/TopEndpoints handling.
 - Update ops UI to display totalBytes in throughput cards and remove a redundant network-specific auto-refresh fetch.
 - Type and state updates: ts_interfaces/data/stats.ts and ts_web/appstate.ts updated with totalBytes and initialization/default mapping adjusted.
 ## 2026-02-13 - 5.4.0 - feat(certificates)
 include certificate source/issuer and Rust-side status checks; pass eventComms into certProvisionFunction and record expiry information
 - bump @push.rocks/smartproxy dependency to ^25.0.0
 - add optional 'source' field to certificate status and propagate event.source when certificates are issued, renewed, or failed
 - change smartProxy.certProvisionFunction signature to accept eventComms; use it to log attempts, set source and expiryDate, and fall back to http-01 on DNS-01 failure
 - make buildCertificateOverview async and query smartProxy.getCertificateStatus for a route when event-based status is unknown
 - improve logging to include certificate source and more contextual messages
 ## 2026-02-13 - 5.3.0 - feat(certificates)
 add certificate overview and reprovisioning in ops UI and API; track SmartProxy certificate events
 - Add CertificateHandler with typedrequest endpoints: getCertificateOverview and reprovisionCertificate
 - Introduce ICertificateInfo and request/response interfaces for certificate operations
 - Frontend: add certificate state part, actions (fetchCertificateOverview, reprovisionCertificate), router view, and ops-view-certificates component
 - DcRouter: add certificateStatusMap, listen to SmartProxy certificate-issued/renewed/failed events, and add findRouteNameForDomain helper
 - Bump dependency @push.rocks/smartproxy to ^24.0.0
 ## 2026-02-13 - 5.2.0 - feat(monitoring)
 add throughput metrics and expose them in ops UI
 - MetricsManager now reports bytesInPerSecond and bytesOutPerSecond as part of throughput
 - Extended IServerStats with requestsPerSecond and throughput {bytesIn, bytesOut, bytesInPerSecond, bytesOutPerSecond}
 - Stats handler updated to include requestsPerSecond and throughput; fallback stats initialize throughput fields to zero
 - Web UI ops overview displays Throughput In/Out (bits/s) and total bytes with new formatting helper
 - Bumped dependency @push.rocks/smartproxy to ^23.1.6
 ## 2026-02-13 - 5.1.0 - feat(acme)
 Integrate SmartAcme DNS-01 handling and add certificate provisioning for SmartProxy
 - Add smartAcme property and lifecycle management (start/stop) in DcRouter
 - Create SmartAcme instance when DNS challenge handlers are present and wire certProvisionFunction to SmartProxy to return certificates for domains
 - Fall back to http-01 provisioning on SmartAcme errors for a domain
 - Stop SmartAcme during shutdown sequence to clean up resources
 - Bump dependency @push.rocks/smartproxy to ^23.1.5
 ## 2026-02-13 - 5.0.7 - fix(deps)
 bump @push.rocks/smartdns to ^7.8.1 and @push.rocks/smartmta to ^5.2.2
 - package.json: updated @push.rocks/smartdns from ^7.8.0 to ^7.8.1 (patch)
 - package.json: updated @push.rocks/smartmta from ^5.2.1 to ^5.2.2 (patch)
 ## 2026-02-12 - 5.0.6 - fix(deps)
 bump @push.rocks/smartproxy to ^23.1.4
 - package.json: @push.rocks/smartproxy ^23.1.2 → ^23.1.4
 - Dependency-only version bump, no source code changes
 ## 2026-02-12 - 5.0.5 - fix(dcrouter)
 remove legacy handling of emailConfig.routes that added domain-based routes
 - Removed loop that added domain-based email routes from emailConfig.routes into emailRoutes
 - Previously created match.domains by extracting the recipient domain (split on '@') and defaulted forward target port to 25
 - Removed creation of TLS passthrough configuration for those forwarded routes
 - This prevents duplicate or incorrect domain-based routes being appended during email route construction
 ## 2026-02-12 - 5.0.4 - fix(cache)
 use user-writable ~/.serve.zone/dcrouter for TsmDB and centralize data path logic
 - Default TsmDB storage changed from /etc/dcrouter/tsmdb to ~/.serve.zone/dcrouter/tsmdb
 - Introduced dcrouterHomeDir, dataDir, and defaultTsmDbPath in ts/paths.ts
 - CacheDb now defaults to defaultTsmDbPath when no storagePath is provided
 - DcRouter initialization updated to use paths.defaultTsmDbPath; README and readme.hints updated to document the new defaults
 - Avoids /etc permission issues and prevents starting a real MongoDB process in tests by using a user-writable default path
 ## 2026-02-12 - 5.0.3 - fix(packaging)
 add files whitelist to package.json and remove Playwright-generated screenshots
 - Add a "files" array to package.json to control published package contents (includes ts/, ts_web/, dist/, dist_*/**, dist_ts/, dist_ts_web/, assets/, cli.js, npmextra.json, readme.md).
 - Remove multiple .playwright-mcp/*.png screenshot files (clean up Playwright test artifacts and reduce repository noise/size).
 ## 2026-02-12 - 5.0.2 - fix(docs)
 update documentation and packaging configuration: document smartmta/smartdns integrations, adjust API method names, and add release registry info
 - README: document SmartDNS as Rust-powered DNS engine and smartmta as TypeScript+Rust MTA; add Rust-powered architecture section and component package table
 - README: update Node.js requirement from 18+ to 20+; replace embedded cache DB TsmDb with LocalTsmDb and reduce listed cached document types
 - README & ts_interfaces: rename typedrequest API adminLogin -> adminLoginWithUsernameAndPassword and add/clarify several API methods (logout, suppression management, RADIUS client/VLAN helpers)
 - README: update test instructions, change test file references and add a test coverage table
 - npmextra.json: re-key package configs (@git.zone/cli, @ship.zone/szci), tidy watch array formatting, and add release.registries and accessLevel for publishing
 ## 2026-02-11 - 5.0.1 - fix(deps/tests)
 bump two dependencies and disable cache in tests
 - Bumped @api.global/typedrequest from ^3.2.5 to ^3.2.6
 - Bumped @push.rocks/smartradius from ^1.1.0 to ^1.1.1
 - Disabled cache in tests by adding cacheConfig: { enabled: false } to DcRouter instantiation in test/test.jwt-auth.ts, test/test.opsserver-api.ts, and test/test.protected-endpoint.ts
 ## 2026-02-11 - 5.0.0 - BREAKING CHANGE(mta)
 migrate internal MTA to @push.rocks/smartmta and remove legacy mail/deliverability implementation
 - Replace ~27k LOC custom MTA (ts/mail/, ts/deliverability/) with @push.rocks/smartmta v5.2.1 (TypeScript+Rust hybrid)
 - Remove many SMTP client/server test suites and test helpers; testing approach and fixtures changed/removed
 - Upgrade dependencies: @push.rocks/smartproxy -> 23.1.2, @push.rocks/smartdns -> 7.8.0, add @push.rocks/smartmta@5.2.1; bump other minor deps
 - API differences: updateEmailRoutes() replaces updateRoutes(); UnifiedEmailServer exposes dkimCreator publicly; bounce/suppression APIs moved to emailServer.* helpers; Email class and IAttachment types moved into @push.rocks/smartmta exports
 - SmartProxy route validation stricter: forward actions must use targets (array) instead of target (singular) — tests/configs updated accordingly
 - DKIM generation/serving moved to smartmta (dcrouter no longer manages DKIM keys directly)
 ## 2026-02-10 - 4.1.1 - fix(smartproxy)
 upgrade @push.rocks/smartproxy to ^23.1.0 and adapt code/tests for its async getStatistics() API
 - Bumped dependency @push.rocks/smartproxy 22.4.2 → 23.1.0 in package.json
 - Changed ts/monitoring/classes.metricsmanager.ts to await smartProxy.getStatistics() (was synchronous)
 - Updated multiple tests to set cacheConfig: { enabled: false } and added socketTimeouts where appropriate
 - Improved SMTP test servers: handle multi-line input, drop data for packet-loss simulation, and ignore socket errors to make tests more robust
 - Added migration notes to readme.hints.md documenting SmartProxy v23.1.0 changes (async getStatistics, Rust proxy behavior)
 ## 2026-02-10 - 4.1.0 - feat(cache)
 add persistent smartdata-backed cache with LocalTsmDb, cache cleaner, and DcRouter integration
 - Introduce CacheDb and CacheCleaner using @push.rocks/smartdata and @push.rocks/smartmongo (LocalTsmDb) for persistent caching
 - Integrate cache initialization, console summary, and graceful shutdown into DcRouter (options.cacheConfig and setupCacheDb())
 - Require svDb() decorators on concrete cache document classes; remove decorators from the abstract CachedDocument base class
 - Switch CacheCleaner to smartdata getInstances() + per-document delete() instead of deleteMany
 - Adapt to LocalTsmDb API changes (folderPath option and start() returning connectionUri) and initialize SmartdataDb with mongoDbUrl/mongoDbName
 - Remove experimentalDecorators and emitDecoratorMetadata from tsconfig to use TC39 Stage 3 decorators (smartdata v7+ compatibility)
 - Add package.json exports mapping (remove main/typings entries) to expose dist entry points
 - Add README documentation for the Smartdata Cache System and configuration/usage examples
 ## 2026-02-03 - 4.0.0 - BREAKING CHANGE(config)
 convert configuration management to read-only; remove updateConfiguration endpoint and client-side editing
 - Removed server-side 'updateConfiguration' TypedHandler and the private updateConfiguration() method; getConfiguration remains as a read-only handler.
 - Removed IReq_UpdateConfiguration interface from request typings; IReq_GetConfiguration marked as read-only.
 - Removed client-side editing functionality: ops-view-config editing state and methods, Edit/Save/Cancel buttons, and updateConfigurationAction; ops-view-config enhanced to display read-only configuration (badges for booleans, array pills, icons, formatted numbers/bytes, empty states, etc.).
 - Tests updated: replaced configuration update tests with verifyIdentity tests and added a read-only configuration access test.
 - Documentation updated to reflect configuration is read-only (readme.md, ts_web/readme.md, ts_interfaces/readme.md, readme.hints.md).
 - Dependencies adjusted: bumped @push.rocks/smartdata to ^7.0.15 and added @push.rocks/smartmongo ^5.1.0; ts/plugins updated to import/export smartmongo.
 ## 2026-02-02 - 3.1.0 - feat(web)
 determine initial UI view from URL and wire selected view to appdash; add interface and web README files; bump various dependencies
 - UI: derive initial active view from window.location.pathname so the dashboard supports deep linking and bookmarks (ts_web/appstate.ts)
 - UI: pass selectedView to dees-simple-appdash by adding a currentViewTab getter in ops-dashboard (ts_web/elements/ops-dashboard.ts)
 - Docs: add TypeScript interfaces README for @serve.zone/dcrouter-interfaces (ts_interfaces/readme.md)
 - Docs: add/update web module README detailing features, routing, and build instructions (ts_web/readme.md) and expand main project README
 - Deps: bump multiple dependencies in package.json (notable bumps: @api.global/typedrequest -> ^3.2.5, @design.estate/dees-catalog -> ^3.42.0, @design.estate/dees-element -> ^2.1.6, @push.rocks/projectinfo -> ^5.0.2, @push.rocks/smartdata -> ^5.16.7, @push.rocks/smartpromise -> ^4.2.3, @push.rocks/smartradius -> ^1.1.0, @push.rocks/smartstate -> ^2.0.30, mailauth -> ^4.12.1)
 ## 2026-02-01 - 3.0.0 - BREAKING CHANGE(deps)
 upgrade major dependencies, migrate action.target to action.targets (array), adapt to SmartRequest API changes, and add RADIUS server support
 - Bumped many major dependencies: @api.global/typedserver 3.x → 8.3.0, @api.global/typedsocket 3.x → 4.1.0, @apiclient.xyz/cloudflare 6.x → 7.1.0, @design.estate/dees-catalog 1.x → 3.41.4, @push.rocks/smartpath 5.x → 6.x, @push.rocks/smartproxy 19.x → 22.x, @push.rocks/smartrequest 2.x → 5.x, uuid 11.x → 13.x, @types/node 25.1.0 → 25.2.0
 ## 2026-02-01 - 2.13.0 - feat(radius)
 add RADIUS server with MAC authentication (MAB), VLAN assignment, accounting and OpsServer API handlers
 - Introduce full RADIUS module under ts/radius: classes.radius.server, classes.vlan.manager, classes.accounting.manager (authentication, VLAN mapping, OUI patterns, accounting, persistence).
 - Integrate RADIUS into DcRouter: add radiusConfig option, setupRadiusServer(), updateRadiusConfig(), start/stop lifecycle handling and startup summary output.
 - Add OpsServer RadiusHandler (ts/opsserver/handlers/radius.handler.ts) exposing TypedRequest endpoints for client management, VLAN mappings, accounting reports and statistics.
 - Add typed request interfaces for RADIUS under ts_interfaces/requests/radius.ts and export them from the requests index.
 - Wire smartradius into plugins (ts/plugins.ts) and export the new module; export RADIUS from ts/index.ts and re-export RADIUS types from classes.dcrouter.
 - Update package.json & npmextra.json: add tswatch script and dev watcher configuration, add @push.rocks/smartradius dependency and a test_watch/devserver.ts dev server entrypoint.
 - Refactor several web UI components (ops-dashboard, ops-view-*) to use 'accessor' for @state properties (small UI state API adjustments).
 - Documentation: update readme.hints.md with RADIUS integration notes and examples.
 ## 2026-02-01 - 2.12.6 - fix(tests)
 update tests and test helpers to current email/DNS APIs, use non-privileged ports, and improve robustness and resilience
 - Email tests: switch to IEmailConfig properties (domains, routes), use router.emailServer (not unifiedEmailServer), change to non-privileged ports (e.g. 2525) and use fs.rmSync for cleanup.
 - SMTP client helper: add pool and domain options; adjust tests to use STARTTLS (secure: false) and tolerate TLS/cipher negotiation failures with try/catch fallbacks.
 - DNS tests: replace dnsDomain with dnsNsDomains and dnsScopes; test route generation without starting services, verify route names/domains, and create socket handlers without binding privileged ports.
 - Socket-handler tests: use high non-standard ports for route/handler tests, verify route naming (email-port-<port>-route), ensure handlers are functions and handle errors gracefully without starting full routers.
 - Integration/storage/rate-limit tests: add waits for async persistence, create/cleanup test directories, return and manage test server instances, relax strict assertions (memory threshold, rate-limiting enforcement) and make tests tolerant of implementation differences.
 - Misc: use getAvailablePort in perf test setup, export tap.start() where appropriate, and generally make tests less brittle by adding try/catch, fallbacks and clearer logs for expected non-deterministic behavior.
 ## 2026-02-01 - 2.12.5 - fix(mail)
 migrate filesystem helpers to fsUtils, update DKIM and mail APIs, harden SMTP client, and bump dependencies
 - Introduce plugins.fsUtils compatibility layer and replace usages of plugins.smartfile.* with plugins.fsUtils.* across storage, routing, deliverability, and paths to support newer smartfile behaviour
 - Update DKIM signing/verifying to new mailauth API: use signingDomain/selector/privateKey and read keys from dkimCreator before signing; adjust verifier fields to use signingDomain
 - Harden SMTP client CommandHandler: add MAX_BUFFER_SIZE, socket close/error handlers, robust cleanup, clear response buffer, and adjust command/data timeouts; reduce default SOCKET_TIMEOUT to 45s
 - Use SmartFileFactory for creating SmartFile attachments and update saving/loading to use fsUtils async/sync helpers
 - Switch test runners to export default tap.start(), relax some memory-test thresholds, and add test helper methods (recordAuthFailure, recordError)
 - Update package.json: simplify bundle script and bump multiple devDependencies/dependencies to compatible versions
 ## 2025-01-29 - 2.13.0 - feat(socket-handler)
 Implement socket-handler mode for DNS and email services, enabling direct socket passing from SmartProxy
 - Add `dnsDomain` configuration option that automatically sets up DNS server with DNS-over-HTTPS (DoH) support
 - Implement socket-handler mode for email services with `useSocketHandler` flag in email configuration
 - Update SmartProxy route generation to create socket-handler actions instead of port forwarding
 - Add automatic route creation for DNS paths `/dns-query` and `/resolve` when dnsDomain is configured
 - Enhance UnifiedEmailServer with `handleSocket` method for direct socket processing
 - Configure DnsServer with `manualHttpsMode: true` to prevent HTTPS port binding while enabling DoH
 - Improve performance by eliminating internal port forwarding overhead
 - Update documentation with socket-handler mode configuration and benefits
 ## 2025-05-16 - 2.12.0 - feat(smartproxy)
 Update documentation and configuration guides to adopt new route-based SmartProxy architecture
 - Revise SmartProxy implementation hints in readme.hints.md to describe route-based configuration with glob pattern matching
 - Add migration examples showing transition from old direct configuration to new route-based style
 - Update DcRouter and SMTP port configuration to generate SmartProxy routes for email handling (ports 25, 587, 465 mapped to internal services)
 - Enhance integration documentation with examples for HTTP and email services using the new SmartProxy routes
 ## 2025-05-16 - 2.11.2 - fix(dependencies)
 Update dependency versions and adjust test imports to use new packages

 # Implementation Hints and Learnings
 ## smartmta Migration (2026-02-11)
 ### Overview
 dcrouter's custom MTA code (~27,149 lines / 68 files in `ts/mail/` + `ts/deliverability/`) has been replaced with `@push.rocks/smartmta` v5.2.1, a TypeScript+Rust hybrid MTA. dcrouter is now an orchestrator that wires together SmartProxy, smartmta, smartdns, smartradius, and OpsServer.
 ### Architecture
 - **No socket-handler mode** — smartmta's Rust SMTP server binds its own ports directly
 - **SmartProxy forward mode only** — external email ports forwarded to internal ports where smartmta listens
 - Email traffic flow: External Port → SmartProxy → Internal Port → smartmta UnifiedEmailServer
 ### Key API Differences (smartmta vs old custom MTA)
 - `updateEmailRoutes()` instead of `updateRoutes()`
 - `dkimCreator` is public (no need for `(this.emailServer as any).dkimCreator`)
 - `bounceManager` is private, but exposed via public methods:
  - `emailServer.getSuppressionList()`
  - `emailServer.getHardBouncedAddresses()`
  - `emailServer.getBounceHistory(email)`
  - `emailServer.removeFromSuppressionList(email)`
 - `Email` class imported from `@push.rocks/smartmta`
 - `IAttachment` type accessed via `Core` namespace: `import { type Core } from '@push.rocks/smartmta'; type IAttachment = Core.IAttachment;`
 ### Deleted Directories
 - `ts/mail/` (60 files) — replaced by smartmta
 - `ts/deliverability/` (3 files) — IPWarmupManager/SenderReputationMonitor will move to smartmta
 - `ts/errors/email.errors.ts`, `ts/errors/mta.errors.ts` — smartmta has its own errors
 - `ts/cache/documents/classes.cached.bounce.ts`, `classes.cached.suppression.ts`, `classes.cached.dkim.ts` — smartmta handles its own persistence
 ### Remaining Cache Documents
 - `CachedEmail` — kept (dcrouter-level queue persistence)
 - `CachedIPReputation` — kept (dcrouter-level IP reputation caching)
 ### Dependencies Removed
 mailauth, mailparser, @types/mailparser, ip, @push.rocks/smartmail, @push.rocks/smartrule, node-forge
 ### Pre-existing Test Failures (not caused by migration)
 - `test/test.jwt-auth.ts` — `response.text is not a function` (webrequest compatibility issue)
 - `test/test.opsserver-api.ts` — same webrequest issue, timeouts
 ### smartmta Location
 Source at `../../push.rocks/smartmta`, release with `gitzone commit -ypbrt`
 ## Dependency Upgrade (2026-02-11)
 ### SmartProxy v23.1.2 Route Validation
 - SmartProxy 23.1.2 enforces stricter route validation
 - Forward actions MUST use `targets` (array) instead of `target` (singular)
 - Test configurations that call `DcRouter.start()` need `cacheConfig: { enabled: false }` to avoid starting a real MongoDB process in tests
 ```typescript
 // WRONG - will fail validation
 action: { type: 'forward', target: { host: 'localhost', port: 10025 } }
 // CORRECT
 action: { type: 'forward', targets: [{ host: 'localhost', port: 10025 }] }
 ```
 **Files Fixed:**
 - `ts/classes.dcrouter.ts` - `generateEmailRoutes()` method
 - `test/test.dcrouter.email.ts` - Updated assertions and added `cacheConfig: { enabled: false }`
 ## Dependency Upgrade (2026-02-10)
 ### SmartProxy v23.1.0 Upgrade
 - `@push.rocks/smartproxy`: 22.4.2 → 23.1.0
 **Key Changes:**
 - Rust-based proxy components for improved performance
 - Rust binary runs as separate process via IPC
 - `getStatistics()` now returns `Promise<any>` (was synchronous)
 - nftables-proxy removed (not used by dcrouter)
 **Code Changes Required:**
 ```typescript
 // Old (synchronous)
 const proxyStats = this.dcRouter.smartProxy.getStatistics();
 // New (async)
 const proxyStats = await this.dcRouter.smartProxy.getStatistics();
 ```
 **Files Modified:**
 - `ts/monitoring/classes.metricsmanager.ts` - Added `await` to `getStatistics()` call
 ## Dependency Upgrade (2026-02-01)
 ### Major Upgrades Completed
 - `@api.global/typedserver`: 3.0.80 → 8.3.0
 - `@api.global/typedsocket`: 3.1.1 → 4.1.0
 - `@apiclient.xyz/cloudflare`: 6.4.3 → 7.1.0
 - `@design.estate/dees-catalog`: 1.12.4 → 3.41.4
 - `@push.rocks/smartpath`: 5.1.0 → 6.0.0
 - `@push.rocks/smartproxy`: 19.6.17 → 22.4.2
 - `@push.rocks/smartrequest`: 2.1.0 → 5.0.1
 - `uuid`: 11.1.0 → 13.0.0
 ### Breaking Changes Fixed
 1. **SmartProxy v22**: `target` → `targets` (array)
   ```typescript
   // Old
   action: { type: 'forward', target: { host: 'x', port: 25 } }
   // New
   action: { type: 'forward', targets: [{ host: 'x', port: 25 }] }
   ```
 2. **SmartRequest v5**: `SmartRequestClient` → `SmartRequest`, `.body` → `.json()`
   ```typescript
   // Old
   const resp = await plugins.smartrequest.SmartRequestClient.create()...post();
   const json = resp.body;
   // New
   const resp = await plugins.smartrequest.SmartRequest.create()...post();
   const json = await resp.json();
   ```
 3. **dees-catalog v3**: Icon naming changed to library-prefixed format
   ```typescript
   // Old (deprecated but supported)
   <dees-icon iconFA="check"></dees-icon>
   // New
   <dees-icon icon="fa:check"></dees-icon>
   <dees-icon icon="lucide:menu"></dees-icon>
   ```
 ### TC39 Decorators
 - ts_web components updated to use `accessor` keyword for `@state()` decorators
 - Required for TC39 standard decorator support
 ### tswatch Configuration
 The project now uses tswatch for development:
 ```bash
 pnpm run watch
 ```
 Configuration in `npmextra.json`:
 ```json
 {
  "@git.zone/tswatch": {
    "watchers": [{
      "name": "dcrouter-dev",
      "watch": ["ts/**/*.ts", "ts_*/**/*.ts", "test_watch/devserver.ts"],
      "command": "pnpm run build && tsrun test_watch/devserver.ts",
      "restart": true,
      "debounce": 500,
      "runOnStart": true
    }]
  }
 }
 ```
 ## RADIUS Server Integration (2026-02-01)
 ### Overview
 DcRouter now supports RADIUS server functionality for network authentication via `@push.rocks/smartradius`.
 ### Key Features
 - **MAC Authentication Bypass (MAB)** - Authenticate network devices based on MAC address
 - **VLAN Assignment** - Assign VLANs based on MAC address or OUI patterns
 - **RADIUS Accounting** - Track sessions, data usage, and billing
 ### Configuration Example
 ```typescript
 const dcRouter = new DcRouter({
  radiusConfig: {
    authPort: 1812,      // Authentication port (default)
    acctPort: 1813,      // Accounting port (default)
    clients: [
      {
        name: 'switch-1',
        ipRange: '192.168.1.0/24',
        secret: 'shared-secret',
        enabled: true
      }
    ],
    vlanAssignment: {
      defaultVlan: 100,   // VLAN for unknown MACs
      allowUnknownMacs: true,
      mappings: [
        { mac: '00:11:22:33:44:55', vlan: 10, enabled: true },
        { mac: '00:11:22', vlan: 20, enabled: true }  // OUI pattern
      ]
    },
    accounting: {
      enabled: true,
      retentionDays: 30
    }
  }
 });
 ```
 ### Components
 - `RadiusServer` - Main server wrapping smartradius
 - `VlanManager` - MAC-to-VLAN mapping with OUI pattern support
 - `AccountingManager` - Session tracking and billing data
 ### OpsServer API Endpoints
 - `getRadiusClients` / `setRadiusClient` / `removeRadiusClient` - Client management
 - `getVlanMappings` / `setVlanMapping` / `removeVlanMapping` - VLAN mappings
 - `testVlanAssignment` - Test what VLAN a MAC would get
 - `getRadiusSessions` / `disconnectRadiusSession` - Session management
 - `getRadiusStatistics` / `getRadiusAccountingSummary` - Statistics
 ### Files
 - `ts/radius/` - RADIUS module
 - `ts/opsserver/handlers/radius.handler.ts` - OpsServer handler
 - `ts_interfaces/requests/radius.ts` - TypedRequest interfaces
 ## Test Fix: test.dcrouter.email.ts (2026-02-01)
 ### Issue
 The test `DcRouter class - Custom email storage path` was failing with "domainConfigs is not iterable".
 ### Root Cause
 The test was using outdated email config properties:
 - Used `domainRules: []` (non-existent property)
 - Used `defaultMode` (non-existent property)
 - Missing required `domains: []` property
 - Missing required `routes: []` property
 - Referenced `router.unifiedEmailServer` instead of `router.emailServer`
 ### Fix
 Updated the test to use the correct `IUnifiedEmailServerOptions` interface properties:
 ```typescript
 const emailConfig: IEmailConfig = {
  ports: [2525],
  hostname: 'mail.example.com',
  domains: [], // Required: domain configurations
  routes: []   // Required: email routing rules
 };
 ```
 And fixed the property name:
 ```typescript
 expect(router.emailServer).toBeTruthy();  // Not unifiedEmailServer
 ```
 ### Key Learning
 When using `IUnifiedEmailServerOptions` (aliased as `IEmailConfig` in some tests):
 - `domains: IEmailDomainConfig[]` is required (array of domain configs)
 - `routes: IEmailRoute[]` is required (email routing rules)
 - Access the email server via `dcRouter.emailServer` not `dcRouter.unifiedEmailServer`
 ## Network Metrics Implementation (2025-06-23)
 ### SmartProxy Metrics API Integration
 - Updated to use new SmartProxy metrics API (v19.6.7)
 - Use `getMetrics()` for detailed metrics with grouped methods:
  ```typescript
  const metrics = smartProxy.getMetrics();
  metrics.connections.active()      // Current active connections
  metrics.throughput.instant()      // Real-time throughput {in, out}
  metrics.connections.topIPs(10)    // Top 10 IPs by connection count
  ```
 - Use `getStatistics()` for basic stats
 ### Network Traffic Display
 - All throughput values shown in bits per second (kbit/s, Mbit/s, Gbit/s)
 - Conversion: `bytesPerSecond * 8 / 1000000` for Mbps
 - Network graph shows separate lines for inbound (green) and outbound (purple)
 - Throughput tiles and graph use same data source for consistency
 ### Requests/sec vs Connections
 - Requests/sec shows HTTP request counts (derived from connections)
 - Single connection can handle multiple requests
 - Current implementation tracks connections, not individual requests
 - Trend line shows historical request counts, not throughput
 ## DKIM Implementation Status (2025-05-30)
 **Note:** DKIM is now handled by `@push.rocks/smartmta`. The `dkimCreator` is a public property on `UnifiedEmailServer`.
 ## SmartProxy Usage
 ### New Route-Based Architecture (v18+)
 - SmartProxy now uses a route-based configuration system
 - Routes define match criteria and actions instead of simple port-to-port forwarding
 - All traffic types (HTTP, HTTPS, TCP, WebSocket) are configured through routes
 ```typescript
 // NEW: Route-based SmartProxy configuration
 const smartProxy = new plugins.smartproxy.SmartProxy({
  routes: [
    {
      name: 'https-traffic',
      match: {
        ports: 443,
        domains: ['example.com', '*.example.com']
      },
      action: {
        type: 'forward',
        target: {
          host: 'backend.server.com',
          port: 8080
        }
      },
      tls: {
        mode: 'terminate',
        certificate: 'auto'
      }
    }
  ],
  defaults: {
    target: {
      host: 'fallback.server.com',
      port: 8080
    }
  },
  acme: {
    accountEmail: 'admin@example.com',
    enabled: true,
    useProduction: true
  }
 });
 ```
 ### Migration from Old to New
 ```typescript
 // OLD configuration style (deprecated)
 {
  fromPort: 443,
  toPort: 8080,
  targetIP: 'backend.server.com',
  domainConfigs: [...]
 }
 // NEW route-based style
 {
  routes: [{
    name: 'main-route',
    match: { ports: 443 },
    action: {
      type: 'forward',
      target: { host: 'backend.server.com', port: 8080 }
    }
  }]
 }
 ```
 ### Direct Component Usage
 - Use SmartProxy components directly instead of creating your own wrappers
 - SmartProxy already includes Port80Handler and NetworkProxy functionality
 - When using SmartProxy, configure it directly rather than instantiating Port80Handler or NetworkProxy separately
 ```typescript
 // PREFERRED: Use SmartProxy with built-in ACME support
 const smartProxy = new plugins.smartproxy.SmartProxy({
  fromPort: 443,
  toPort: targetPort,
  targetIP: targetServer,
  sniEnabled: true,
  acme: {
    port: 80,
    enabled: true,
    autoRenew: true,
    useProduction: true,
    renewThresholdDays: 30,
    accountEmail: contactEmail
  },
  globalPortRanges: [{ from: 443, to: 443 }],
  domainConfigs: [/* domain configurations */]
 });
 ```

 ## Email Integration with SmartProxy
 ### Architecture (Post-Migration)
 - Email traffic is routed through SmartProxy using automatic route generation
 - smartmta's UnifiedEmailServer runs on internal ports and receives forwarded traffic from SmartProxy
 - SmartProxy handles external ports (25, 587, 465) and forwards to internal ports
 - smartmta's Rust SMTP bridge handles SMTP protocol processing
 ### Port Mapping
 - External port 25 → Internal port 10025 (SMTP)
 - External port 587 → Internal port 10587 (Submission)
 - External port 465 → Internal port 10465 (SMTPS)
 ### TLS Handling
 - Ports 25 and 587: Use 'passthrough' mode (STARTTLS handled by smartmta)
 - Port 465: Use 'terminate' mode (SmartProxy handles TLS termination)
 ## SmartMetrics Integration (2025-06-12) - COMPLETED
 ### Overview
 Fixed the UI metrics display to show accurate CPU and memory data from SmartMetrics.
 ### Key Findings
 1. **CPU Metrics:**
   - SmartMetrics provides `cpuUsageText` as a string percentage
   - MetricsManager parses it as `cpuUsage.user` (system is always 0)
   - UI was incorrectly dividing by 2, showing half the actual CPU usage
 2. **Memory Metrics:**
   - SmartMetrics calculates `maxMemoryMB` as minimum of:
     - V8 heap size limit
     - System total memory
     - Docker memory limit (if available)
   - Provides `memoryUsageBytes` (total process memory including children)
   - Provides `memoryPercentage` (pre-calculated percentage)
   - UI was only showing heap usage, missing actual memory constraints
 ### Changes Made
 1. **MetricsManager Enhanced:**
   - Added `maxMemoryMB` from SmartMetrics instance
   - Added `actualUsageBytes` from SmartMetrics data
   - Added `actualUsagePercentage` from SmartMetrics data
   - Kept existing memory fields for compatibility
 2. **Interface Updated:**
   - Added optional fields to `IServerStats.memoryUsage`
   - Fields are optional to maintain backward compatibility
 3. **UI Fixed:**
   - Removed incorrect CPU division by 2
   - Uses `actualUsagePercentage` when available (falls back to heap percentage)
   - Shows actual memory usage vs max memory limit (not just heap)
 ### Result
 - CPU now shows accurate usage percentage
 - Memory shows percentage of actual constraints (Docker/system/V8 limits)
 - Better monitoring for containerized environments
 ## Network UI Implementation (2025-06-20) - COMPLETED
 ### Overview
 Revamped the Network UI to display real network data from SmartProxy instead of mock data.
 ### Architecture
 1. **MetricsManager Integration:**
   - Already integrates with SmartProxy via `dcRouter.smartProxy.getStats()`
   - Extended with `getNetworkStats()` method to expose unused metrics:
     - `getConnectionsByIP()` - Connection counts by IP address
     - `getThroughputRate()` - Real-time bandwidth rates (bytes/second)
     - `getTopIPs()` - Top connecting IPs sorted by connection count
   - Note: SmartProxy base interface doesn't include all methods, manual implementation required
 2. **Existing Infrastructure Leveraged:**
   - `getActiveConnections` endpoint already exists in security.handler.ts
   - Enhanced to include real SmartProxy data via MetricsManager
   - IConnectionInfo interface already supports network data structures
 3. **State Management:**
   - Added `INetworkState` interface following existing patterns
   - Created `networkStatePart` with connections, throughput, and IP data
   - Integrated with existing auto-refresh mechanism
 4. **UI Changes (Minimal):**
   - Removed `generateMockData()` method and all mock generation
   - Connected to real `networkStatePart` state
   - Added `renderTopIPs()` section to display top connected IPs
   - Updated traffic chart to show real request data
   - Kept all existing UI components (DeesTable, DeesChartArea)
 ### Implementation Details
 1. **Data Transformation:**
   - Converts IConnectionInfo[] to INetworkRequest[] for table display
   - Calculates traffic buckets based on selected time range
   - Maps connection data to chart-compatible format
 2. **Real Metrics Displayed:**
   - Active connections count (from server stats)
   - Requests per second (calculated from recent connections)
   - Throughput rates (currently showing 0 until SmartProxy exposes rates)
   - Top IPs with connection counts and percentages
 3. **TypeScript Fixes:**
   - SmartProxy methods like `getThroughputRate()` not in base interface
   - Implemented manual fallbacks for missing methods
   - Fixed `publicIpv4` → `publicIp` property name
 ### Result
 - Network view now shows real connection activity
 - Auto-refreshes with other stats every second
 - Displays actual IPs and connection counts
 - No more mock/demo data
 - Minimal code changes (streamlined approach)
 ### Throughput Data Fix (2025-06-20)
 The throughput was showing 0 because:
 1. MetricsManager was hardcoding throughputRate to 0, assuming the method didn't exist
 2. SmartProxy's `getStats()` returns `IProxyStats` interface, but the actual object (`MetricsCollector`) implements `IProxyStatsExtended`
 3. `getThroughputRate()` only exists in the extended interface
 **Solution implemented:**
 1. Updated MetricsManager to check if methods exist at runtime and call them
 2. Added property name mapping (`bytesInPerSec` → `bytesInPerSecond`)
 3. Created new `getNetworkStats` endpoint in security.handler.ts
 4. Updated frontend to call the new endpoint for complete network metrics
 The throughput data now flows correctly from SmartProxy → MetricsManager → API → UI.
 ## Email Operations Dashboard (2026-02-01)
 ### Overview
 Replaced mock data in the email UI with real backend data from the delivery queue and security logger.
 ### New Files Created
 - `ts_interfaces/requests/email-ops.ts` - TypedRequest interfaces for email operations
 - `ts/opsserver/handlers/email-ops.handler.ts` - Backend handler for email operations
 ### Key Interfaces
 - `IReq_GetQueuedEmails` - Fetch emails from delivery queue by status
 - `IReq_GetSentEmails` - Fetch delivered emails
 - `IReq_GetFailedEmails` - Fetch failed emails
 - `IReq_ResendEmail` - Re-queue a failed email for retry
 - `IReq_GetSecurityIncidents` - Fetch security events from SecurityLogger
 - `IReq_GetBounceRecords` - Fetch bounce records and suppression list
 - `IReq_RemoveFromSuppressionList` - Remove email from suppression list
 ### UI Changes (ops-view-emails.ts)
 - Replaced mock folders (inbox/sent/draft/trash) with operations views:
  - **Queued**: Emails pending delivery
  - **Sent**: Successfully delivered emails
  - **Failed**: Failed emails with resend capability
  - **Security**: Security incidents from SecurityLogger
 - Removed `generateMockEmails()` method
 - Added state management via `emailOpsStatePart` in appstate.ts
 - Added resend button for failed emails
 - Added security incident detail view
 ### Data Flow
 ```
 UnifiedDeliveryQueue → EmailOpsHandler → TypedRequest → Frontend State → UI
 SecurityLogger → EmailOpsHandler → TypedRequest → Frontend State → UI
 BounceManager → EmailOpsHandler → TypedRequest → Frontend State → UI
 ```
 ### Backend Data Access
 The handler accesses data from:
 - `dcRouter.emailServer.deliveryQueue` - Email queue items (IQueueItem)
 - `SecurityLogger.getInstance()` - Security events (ISecurityEvent)
 - `emailServer.bounceManager` - Bounce records and suppression list
 ## OpsServer UI Fixes (2026-02-02)
 ### Configuration Page Fix
 The configuration page had field name mismatches between frontend and backend:
 - Frontend expected `server` and `storage` sections
 - Backend returns `proxy` section (not `server`)
 - Backend has no `storage` section
 **Fix**: Updated `ops-view-config.ts` to use correct section names:
 - `proxy` instead of `server`
 - Removed non-existent `storage` section
 - Added optional chaining (`?.`) for safety
 ### Auth Persistence Fix
 Login state was using `'soft'` mode in Smartstate which is memory-only:
 - User login was lost on page refresh
 - State reset to logged out after browser restart
 **Changes**:
 1. `ts_web/appstate.ts`: Changed loginStatePart from `'soft'` to `'persistent'`
   - Now uses IndexedDB to persist across browser sessions
 2. `ts/opsserver/handlers/admin.handler.ts`: JWT expiry changed from 7 days to 24 hours
 3. `ts_web/elements/ops-dashboard.ts`: Added JWT expiry check on session restore
   - Validates stored JWT hasn't expired before auto-logging in
   - Clears expired sessions and shows login form
 ## Config UI Read-Only Conversion (2026-02-03)
 ### Overview
 The configuration UI has been converted from an editable interface to a read-only display. DcRouter is configured through code or remotely, not through the UI.
 ### Changes Made
 1. **Backend (`ts/opsserver/handlers/config.handler.ts`)**:
   - Removed `updateConfiguration` handler
   - Removed `updateConfiguration()` private method
   - Kept `getConfiguration` handler (read-only)
 2. **Interfaces (`ts_interfaces/requests/config.ts`)**:
   - Removed `IReq_UpdateConfiguration` interface
   - Kept `IReq_GetConfiguration` interface
 3. **Frontend (`ts_web/elements/ops-view-config.ts`)**:
   - Removed `editingSection` and `editedConfig` state properties
   - Removed `startEdit()`, `cancelEdit()`, `saveConfig()` methods
   - Removed Edit/Save/Cancel buttons
   - Removed warning banner about immediate changes
   - Enhanced read-only display with:
     - Status badges for boolean values (enabled/disabled)
     - Array display as pills/tags with counts
     - Section icons (mail, globe, network, shield)
     - Better formatting for numbers and byte sizes
     - Empty state handling ("Not configured", "None configured")
     - Info note explaining configuration is read-only
 4. **State Management (`ts_web/appstate.ts`)**:
   - Removed `updateConfigurationAction`
   - Kept `fetchConfigurationAction` (read-only)
 5. **Tests (`test/test.protected-endpoint.ts`)**:
   - Replaced `updateConfiguration` tests with `verifyIdentity` tests
   - Added test for read-only config access
   - Kept auth flow testing with different protected endpoint
 6. **Documentation**:
   - `readme.md`: Updated API endpoints to show config as read-only
   - `ts_web/readme.md`: Removed `updateConfigurationAction` from actions list
   - `ts_interfaces/readme.md`: Removed `IReq_UpdateConfiguration` from table
 ### Visual Display Features
 - Boolean values shown as colored badges (green=enabled, red=disabled)
 - Arrays displayed as pills with count summaries
 - Section headers with relevant Lucide icons
 - Numbers formatted with locale separators
 - Byte sizes auto-formatted (B, KB, MB, GB)
 - Time values shown with "seconds" suffix
 - Nested objects with visual indentation
 ## Smartdata Cache System (2026-02-03)
 ### Overview
 DcRouter now uses smartdata + LocalTsmDb for persistent caching. Data is stored at `~/.serve.zone/dcrouter/tsmdb`.
 ### Technology Stack
 | Layer | Package | Purpose |
 |-------|---------|---------|
 | ORM | `@push.rocks/smartdata` | Document classes, decorators, queries |
 | Database | `@push.rocks/smartmongo` (LocalTsmDb) | Embedded TsmDB via Unix socket |
 ### TC39 Decorators
 The project uses TC39 Stage 3 decorators (not experimental decorators). The tsconfig was updated:
 - Removed `experimentalDecorators: true`
 - Removed `emitDecoratorMetadata: true`
 This is required for smartdata v7+ compatibility.
 ### Cache Document Classes
 Located in `ts/cache/documents/`:
 | Class | Purpose | Default TTL |
 |-------|---------|-------------|
 | `CachedEmail` | Email queue items | 30 days |
 | `CachedIPReputation` | IP reputation lookups | 24 hours |
 Note: CachedBounce, CachedSuppression, and CachedDKIMKey were removed in the smartmta migration (smartmta handles its own persistence for those).
 ### Usage Pattern
 ```typescript
 // Document classes use smartdata decorators
@plugins.smartdata.Collection(() => getDb())
 export class CachedEmail extends CachedDocument<CachedEmail> {
  @plugins.smartdata.svDb()
  public createdAt: Date = new Date();
  @plugins.smartdata.svDb()
  public expiresAt: Date = new Date(Date.now() + TTL.DAYS_30);
  @plugins.smartdata.unI()
  @plugins.smartdata.svDb()
  public id: string;
  // ...
 }
 // Query examples
 const email = await CachedEmail.getInstance({ id: 'abc123' });
 const pending = await CachedEmail.getInstances({ status: 'pending' });
 await email.save();
 await email.delete();
 ```
 ### Configuration
 ```typescript
 const dcRouter = new DcRouter({
  cacheConfig: {
    enabled: true,
    storagePath: '~/.serve.zone/dcrouter/tsmdb',
    dbName: 'dcrouter',
    cleanupIntervalHours: 1,
    ttlConfig: {
      emails: 30,       // days
      ipReputation: 1,  // days
      bounces: 30,      // days
      dkimKeys: 90,     // days
      suppression: 30   // days
    }
  }
 });
 ```
 ### Cache Cleaner
 - Runs hourly by default (configurable via `cleanupIntervalHours`)
 - Finds and deletes documents where `expiresAt < now()`
 - Uses smartdata's `getInstances()` + `delete()` pattern
 ### Key Files
 - `ts/cache/classes.cachedb.ts` - CacheDb singleton wrapper
 - `ts/cache/classes.cached.document.ts` - Base class with TTL support
 - `ts/cache/classes.cache.cleaner.ts` - Periodic cleanup service
 - `ts/cache/documents/*.ts` - Document class definitions

 # Smartlog Improvement Plan
 ## Overview
 This document outlines a plan for enhancing the `@push.rocks/smartlog` module to incorporate the advanced features currently implemented in the custom `EnhancedLogger` wrapper. By moving these features directly into `smartlog`, we can eliminate the need for wrapper classes while providing a more comprehensive logging solution.
 ## Current Limitations in Smartlog
 - Limited context management (no hierarchical contexts)
 - No correlation ID tracking for distributed tracing
 - No built-in filtering or log level management
 - No log sampling capabilities
 - No middleware for HTTP request/response logging
 - No timing utilities for performance tracking
 - No child logger functionality with context inheritance
 ## Proposed Enhancements
 ### 1. Context Management
 - Add hierarchical context support
 - Implement methods for manipulating context:
  - `setContext(context, overwrite = false)`
  - `addToContext(key, value)`
  - `removeFromContext(key)`
 ### 2. Correlation ID Tracking
 - Add correlation ID support for distributed tracing
 - Implement methods for correlation management:
  - `setCorrelationId(id = null)`
  - `getCorrelationId()`
  - `clearCorrelationId()`
 ### 3. Log Filtering
 - Implement configurable log filtering based on:
  - Minimum log level
  - Pattern-based exclusion rules
  - Custom filtering functions
 ### 4. Log Sampling
 - Add probabilistic log sampling for high-volume environments
 - Support for enforcing critical logs (e.g., errors) regardless of sampling
 ### 5. Child Loggers
 - Support creating child loggers with inherited context
 - Allow context overrides in child loggers
 ### 6. Timing Utilities
 - Add methods for timing operations:
  - `logTimed(level, message, fn, context)`
  - Support for both async and sync operations
 ### 7. HTTP Request Logging
 - Add middleware for Express/Fastify/other HTTP frameworks
 - Auto-capture request/response data
 - Auto-propagate correlation IDs
 ### 8. Log Standardization
 - Ensure consistent output format
 - Add standard fields like timestamp, correlation ID
 - Support for custom formatters
 ## Implementation Plan
 1. **Core Enhancements**
   - Implement context management
   - Add correlation ID tracking
   - Develop filtering and sampling capabilities
 2. **Extended Features**
   - Build child logger functionality
   - Create timing utility methods
   - Implement HTTP middleware
 3. **Compatibility**
   - Ensure backward compatibility
   - Provide migration guide
   - Add TypeScript declarations
 4. **Documentation**
   - Update README with new features
   - Add examples for each feature
   - Document best practices
 ## Migration Path
 After implementing these enhancements to `smartlog`, the migration would involve:
 1. Update to latest `smartlog` version
 2. Replace `EnhancedLogger` instances with `smartlog.Smartlog`
 3. Update configuration to use new capabilities
 4. Replace middleware with `smartlog`'s built-in solutions
 ## Benefits
 - Simplified dependency tree
 - Better maintainability with single logging solution
 - Improved performance with native implementation
 - Enhanced type safety through TypeScript
 - Standardized logging across projects

 - **Memory Usage**: <500MB for 1000 concurrent email operations
 - **DNS Cache Hit Rate**: >90% for repeated domains
 - **Retry Success Rate**: >95% for temporary failures
 - **Large Attachment Support**: Files up to 25MB without performance degradation
 - **Queue Processing**: >1000 emails/minute with persistent queue
 ## Client Security Requirements
 All client security tests must pass for production deployment:
 - **TLS Support**: TLS 1.2+ required, TLS 1.3 preferred
 - **Authentication**: Support for LOGIN, PLAIN, CRAM-MD5, OAuth2
 - **Certificate Validation**: Proper certificate chain validation
 - **DKIM Signing**: Automatic DKIM signature generation
 - **Credential Security**: No plaintext password storage
 - **Injection Prevention**: Protection against header/command injection
 ## Client Production Readiness Criteria
 ### Production Gate 1: Core Functionality (>95% tests passing)
 - Basic connection establishment
 - Command execution and response parsing
 - Email composition and sending
 - Error handling and recovery
 ### Production Gate 2: Advanced Features (>90% tests passing)
 - Connection pooling and reuse
 - Authentication mechanisms
 - TLS/STARTTLS support
 - Retry logic and resilience
 ### Production Gate 3: Enterprise Ready (>85% tests passing)
 - High-volume sending capabilities
 - Advanced security features
 - Full RFC compliance
 - Performance under load
 ## Key Differences: Server vs Client Tests
 | Aspect | Server Tests | Client Tests |
 |--------|--------------|--------------|
 | **Focus** | Accepting connections, processing commands | Making connections, sending commands |
 | **Security** | Validating incoming data, enforcing policies | Protecting credentials, validating servers |
 | **Performance** | Handling many clients concurrently | Efficient bulk sending, connection reuse |
 | **Reliability** | Staying up under attack/load | Retrying failures, handling timeouts |
 | **RFC Compliance** | Server MUST requirements | Client MUST requirements |
 ## Test Implementation Priority
 1. **Critical** (implement first):
   - Basic connection and command sending
   - Authentication mechanisms
   - Error handling and retry logic
   - TLS/Security features
 2. **High Priority** (implement second):
   - Connection pooling
   - Email composition and MIME
   - Performance optimization
   - RFC compliance
 3. **Medium Priority** (implement third):
   - Advanced features (OAuth2, etc.)
   - Edge case handling
   - Extended performance tests
   - Additional RFC extensions
 4. **Low Priority** (implement last):
   - Proxy support
   - Certificate pinning
   - Unusual scenarios
   - Optional RFC features

 # DCRouter Test Configuration
 ## Running Tests
 ### Run All Tests
 ```bash
 cd dcrouter
 pnpm test
 ```
 ### Run Specific Category
 ```bash
 # Run all connection tests
 tsx test/run-category.ts connection
 # Run all security tests  
 tsx test/run-category.ts security
 # Run all performance tests
 tsx test/run-category.ts performance
 ```
 ### Run Individual Test File
 ```bash
 # Run TLS connection test
 tsx test/suite/connection/test.tls-connection.ts
 # Run authentication test
 tsx test/suite/security/test.authentication.ts
 ```
 ### Run Tests with Verbose Output
 ```bash
 # All tests with verbose logging
 pnpm test -- --verbose
 # Individual test with verbose
 tsx test/suite/connection/test.tls-connection.ts --verbose
 ```
 ## Test Server Configuration
 Each test file starts its own SMTP server with specific configuration. Common configurations:
 ### Basic Server
 ```typescript
 const testServer = await startTestServer({
  port: 2525,
  hostname: 'localhost'
 });
 ```
 ### TLS-Enabled Server
 ```typescript
 const testServer = await startTestServer({
  port: 2525,
  hostname: 'localhost',
  tlsEnabled: true
 });
 ```
 ### Authenticated Server
 ```typescript
 const testServer = await startTestServer({
  port: 2525,
  hostname: 'localhost',
  authRequired: true
 });
 ```
 ### High-Performance Server
 ```typescript
 const testServer = await startTestServer({
  port: 2525,
  hostname: 'localhost',
  maxConnections: 1000,
  size: 50 * 1024 * 1024 // 50MB
 });
 ```
 ## Port Allocation
 Tests use different ports to avoid conflicts:
 - Connection tests: 2525-2530
 - Command tests: 2531-2540
 - Email processing: 2541-2550
 - Security tests: 2551-2560
 - Performance tests: 2561-2570
 - Edge cases: 2571-2580
 - RFC compliance: 2581-2590
 ## Test Utilities
 ### Server Lifecycle
 All tests follow this pattern:
 ```typescript
 import { tap, expect } from '@git.zone/tstest/tapbundle';
 import { startTestServer, stopTestServer } from '../../helpers/server.loader.js';
 let testServer;
 tap.test('setup', async () => {
  testServer = await startTestServer({ port: 2525 });
 });
 // Your tests here...
 tap.test('cleanup', async () => {
  await stopTestServer(testServer);
 });
 tap.start();
 ```
 ### SMTP Client Testing
 ```typescript
 import { createTestSmtpClient } from '../../helpers/smtp.client.js';
 const client = createTestSmtpClient({
  host: 'localhost',
  port: 2525
 });
 ```
 ### Low-Level SMTP Testing
 ```typescript
 import { connectToSmtp, sendSmtpCommand } from '../../helpers/test.utils.js';
 const socket = await connectToSmtp('localhost', 2525);
 const response = await sendSmtpCommand(socket, 'EHLO test.example.com', '250');
 ```
 ## Performance Benchmarks
 Expected minimums for production:
 - Throughput: >10 emails/second
 - Concurrent connections: >100
 - Memory increase: <2% under load
 - Connection time: <5000ms
 - Error rate: <5%
 ## Debugging Failed Tests
 ### Enable Verbose Logging
 ```bash
 DEBUG=* tsx test/suite/connection/test.tls-connection.ts
 ```
 ### Check Server Logs
 Tests output server logs to console. Look for:
 - 🚀 Server start messages
 - 📧 Email processing logs
 - ❌ Error messages
 - ✅ Success confirmations
 ### Common Issues
 1. **Port Already in Use**
   - Tests use unique ports
   - Check for orphaned processes: `lsof -i :2525`
   - Kill process: `kill -9 <PID>`
 2. **TLS Certificate Errors**
   - Tests use self-signed certificates
   - Production should use real certificates
 3. **Timeout Errors**
   - Increase timeout in test configuration
   - Check network connectivity
   - Verify server started successfully
 4. **Authentication Failures**
   - Test servers may not validate credentials
   - Check authRequired configuration
   - Verify AUTH mechanisms supported
