 # Changelog
 
+## 2025-05-02 - 8.0.0 - BREAKING CHANGE(certProvisioner)
+Refactor: Introduce unified CertProvisioner to centralize certificate provisioning and renewal; remove legacy ACME config from Port80Handler and update SmartProxy to delegate certificate lifecycle management.
+
+- Removed deprecated acme properties and renewal scheduler from IPort80HandlerOptions and Port80Handler.
+- Created new CertProvisioner component in ts/smartproxy/classes.pp.certprovisioner.ts to handle static and HTTP-01 certificate workflows.
+- Updated SmartProxy to initialize CertProvisioner and re-emit certificate events.
+- Eliminated legacy renewal logic and associated autoRenew settings from Port80Handler.
+- Adjusted tests to reflect changes in certificate provisioning and renewal behavior.
+
+## 2025-05-01 - 7.2.0 - feat(ACME/Certificate)
+Introduce certificate provider hook and observable certificate events; remove legacy ACME flow
+
+- Extended IPortProxySettings with a new certProvider callback that allows returning a static certificate or 'http01' for ACME challenges.
+- Updated Port80Handler to leverage SmartAcme's getCertificateForDomain and removed outdated methods such as getAcmeClient and processAuthorizations.
+- Enhanced SmartProxy to extend EventEmitter, invoking certProvider on non-wildcard domains and re-emitting certificate events (with domain, publicKey, privateKey, expiryDate, source, and isRenewal flag).
+- Updated NetworkProxyBridge to support applying external certificates via a new applyExternalCertificate method.
+- Revised documentation (readme.md and readme.plan.md) to include usage examples for the new certificate provider hook.
+
+## 2025-04-30 - 7.1.4 - fix(dependencies)

+- Included detailed information on TSConfig settings, Mermaid diagrams, CLI usage, and future TODOs.
+
+## 2025-04-19 - 7.1.2 - fix(networkproxy/requesthandler)
+Improve HTTP/2 request handling and error management in the proxy request handler; add try-catch around routing and update header processing to support per-backend protocol overrides.
+
+- Wrapped the routing call (router.routeReq) in a try-catch block to better handle errors and missing host headers.
+- Returns a 500 error and increments failure metrics if routing fails.
+- Refactored HTTP/2 branch to copy all headers appropriately and map response headers into HTTP/1 response.
+- Added support for per-backend protocol override via the new backendProtocol option in IReverseProxyConfig.
+
+## 2025-04-19 - 7.1.1 - fix(commit-info)
+Update commit metadata and synchronize project configuration (no code changes)
+
+- Verified that all files remain unchanged
+- Commit reflects a metadata or build system sync without functional modifications
+
+## 2025-04-19 - 7.1.0 - feat(core)
+Add backendProtocol option to support HTTP/2 client sessions alongside HTTP/1. This update enhances NetworkProxy's core functionality by integrating HTTP/2 support in server creation and request handling, while updating plugin exports and documentation accordingly.
+
+- Introduced 'backendProtocol' configuration option (http1 | http2) with default 'http1'.
+- Updated creation of secure server to use http2.createSecureServer with HTTP/1 fallback.
+- Enhanced request handling to establish HTTP/2 client sessions when backendProtocol is set to 'http2'.

+
+- Deleted ts/classes.sslredirect.ts which contained the old SSL redirect logic
+- Updated ts/index.ts to export 'redirect/classes.redirect.js' instead of the removed SSL redirect module
+- Adopted a new redirect implementation that provides enhanced features and a more consistent API
+
+## 2025-03-25 - 6.0.1 - fix(readme)
+Update README documentation: replace all outdated 'PortProxy' references with 'SmartProxy', adjust architecture diagrams, code examples, and configuration details (including correcting IPTables to NfTables) to reflect the new naming.
+
+- Renamed 'PortProxy' to 'SmartProxy' in diagrams, flow sequences, and descriptive text
+- Updated code examples and installation instructions accordingly
+- Corrected references from IPTables to NfTables for modern system support

+# SmartProxy Project Hints
+
+## Project Overview
+- Package: `@push.rocks/smartproxy` – high-performance proxy supporting HTTP(S), TCP, WebSocket, and ACME integration.
+- Written in TypeScript, compiled output in `dist_ts/`, uses ESM with NodeNext resolution.
+
+## Repository Structure
+- `ts/` – TypeScript source files:
+  - `index.ts` exports main modules.
+  - `plugins.ts` centralizes native and third-party imports.
+  - Subdirectories: `networkproxy/`, `nftablesproxy/`, `port80handler/`, `redirect/`, `smartproxy/`.
+  - Key classes: `ProxyRouter` (`classes.router.ts`), `SmartProxy` (`classes.smartproxy.ts`), plus handlers/managers.
+- `dist_ts/` – transpiled `.js` and `.d.ts` files mirroring `ts/` structure.
+- `test/` – test suites in TypeScript:
+  - `test.router.ts` – routing logic (hostname matching, wildcards, path parameters, config management).
+  - `test.smartproxy.ts` – proxy behavior tests (TCP forwarding, SNI handling, concurrency, chaining, timeouts).
+  - `test/helpers/` – utilities (e.g., certificates).
+- `assets/certs/` – placeholder certificates for ACME and TLS.
+
+## Development Setup
+- Requires `pnpm` (v10+).
+- Install dependencies: `pnpm install`.
+- Build: `pnpm build` (runs `tsbuild --web --allowimplicitany`).
+- Test: `pnpm test` (runs `tstest test/`).
+- Format: `pnpm format` (runs `gitzone format`).
+
+## Testing Framework
+- Uses `@push.rocks/tapbundle` (`tap`, `expect`, `expactAsync`).
+- Test files: must start with `test.` and use `.ts` extension.
+- Run specific tests via `tsx`, e.g., `tsx test/test.router.ts`.
+
+## Coding Conventions
+- Import modules via `plugins.ts`:
+  ```ts
+  import * as plugins from './plugins.ts';
+  const server = new plugins.http.Server();
+  ```
+- Reference plugins with full path: `plugins.acme`, `plugins.smartdelay`, `plugins.minimatch`, etc.
+- Path patterns support globs (`*`) and parameters (`:param`) in `ProxyRouter`.
+- Wildcard hostname matching leverages `minimatch` patterns.
+
+## Key Components
+- **ProxyRouter**
+  - Methods: `routeReq`, `routeReqWithDetails`.
+  - Hostname matching: case-insensitive, strips port, supports exact, wildcard, TLD, complex patterns.
+  - Path routing: exact, wildcard, parameter extraction (`pathParams`), returns `pathMatch` and `pathRemainder`.
+  - Config API: `setNewProxyConfigs`, `addProxyConfig`, `removeProxyConfig`, `getHostnames`, `getProxyConfigs`.
+- **SmartProxy**
+  - Manages one or more `net.Server` instances to forward TCP streams.
+  - Options: `preserveSourceIP`, `defaultAllowedIPs`, `globalPortRanges`, `sniEnabled`.
+  - DomainConfigManager: round-robin selection for multiple target IPs.
+  - Graceful shutdown in `stop()`, ensures no lingering servers or sockets.
+
+## Notable Points
+- **TSConfig**: `module: NodeNext`, `verbatimModuleSyntax`, allows `.js` extension imports in TS.
+- Mermaid diagrams and architecture flows in `readme.md` illustrate component interactions and protocol flows.
+- CLI entrypoint (`cli.js`) supports command-line usage (ACME, proxy controls).
+- ACME and certificate handling via `Port80Handler` and `helpers.certificates.ts`.
+
+## TODOs / Considerations
+- Ensure import extensions in source match build outputs (`.ts` vs `.js`).
+- Update `plugins.ts` when adding new dependencies.
+- Maintain test coverage for new routing or proxy features.
+- Keep `ts/` and `dist_ts/` in sync after refactors.

+## Certificate Provider Hook & Events
+
+You can customize how certificates are provisioned per domain by using the `certProvider` callback and listen for certificate events emitted by `SmartProxy`.
+
+```typescript
+import { SmartProxy } from '@push.rocks/smartproxy';
+import * as fs from 'fs';
+
+// Example certProvider: static for a specific domain, HTTP-01 otherwise
+const certProvider = async (domain: string) => {
+  if (domain === 'static.example.com') {
+    // Load from disk or vault
+    return {
+      id: 'static-cert',
+      domainName: domain,
+      created: Date.now(),
+      validUntil: Date.now() + 90 * 24 * 60 * 60 * 1000,
+      privateKey: fs.readFileSync('/etc/ssl/private/static.key', 'utf8'),
+      publicKey: fs.readFileSync('/etc/ssl/certs/static.crt', 'utf8'),
+      csr: ''
+    };
+  }
+  // Fallback to ACME HTTP-01 challenge
+  return 'http01';
+};
+
+const proxy = new SmartProxy({
+  fromPort: 80,
+  toPort: 8080,
+  domainConfigs: [{
+    domains: ['static.example.com', 'dynamic.example.com'],
+    allowedIPs: ['*']
+  }],
+  certProvider
+});
+
+// Listen for certificate issuance or renewal
+proxy.on('certificate', (evt) => {
+  console.log(`Certificate for ${evt.domain} ready, expires on ${evt.expiryDate}`);
+});
+
+await proxy.start();
+```
+
+## Configuration Options
+
+### backendProtocol
+
+Type: 'http1' | 'http2' (default: 'http1')
+
+Controls the protocol used when proxying requests to backend services. By default, the proxy uses HTTP/1.x (`http.request`). Setting `backendProtocol: 'http2'` establishes HTTP/2 client sessions (`http2.connect`) to your backends for full end-to-end HTTP/2 support (assuming your backend servers support HTTP/2).
+
+Example:
+```js
+import { NetworkProxy } from '@push.rocks/smartproxy';
+
+const proxy = new NetworkProxy({
+  port: 8443,
+  backendProtocol: 'http2',
+  // other options...
+});

+## Refactor: Introduce a Unified CertProvisioner for Certificate Lifecycle
+
+- [x] Ensure Port80Handler is challenge-only:
+  - Remove any internal scheduling and deprecated ACME flows (`getAcmeClient`, `processAuthorizations`, `handleAcmeChallenge`) from Port80Handler.
+  - Remove legacy ACME options (`renewThresholdDays`, `renewCheckIntervalHours`, `mongoDescriptor`, etc.) from `IPort80HandlerOptions`.
+  - Retain only methods for HTTP-01 challenge and direct renewals (`obtainCertificate`, `renewCertificate`, `getDomainCertificateStatus`).
+- [x] Clean up deprecated `acme` configuration:
+  - Remove the `acme` property from `IPortProxySettings` and all legacy references in code.
+
+- [x] Implement `CertProvisioner` component:
+  - [x] Create class `ts/smartproxy/classes.pp.certprovisioner.ts`.
+  - [x] Constructor accepts:
+    * `domainConfigs: IDomainConfig[]`
+    * `port80Handler: Port80Handler`
+    * `networkProxyBridge: NetworkProxyBridge`
+    * optional `certProvider: (domain) => Promise<ICert | 'http01'>`
+    * `renewThresholdDays`, `renewCheckIntervalHours`, `autoRenew` settings.
+  - Responsibilities:
+    * Initial provisioning: static vs HTTP-01.
+    * Subscribe to Port80Handler events (CERTIFICATE_ISSUED/RENEWED) and to static cert updates.
+    * Re-emit unified `'certificate'` events to SmartProxy.
+    * Central scheduling of renewals via `@push.rocks/taskbuffer`.
+
+- [x] Refactor SmartProxy:
+  - [x] Remove existing scheduling / renewal logic.
+  - [x] Instantiate `CertProvisioner` in `start()`, delegate cert workflows entirely.
+  - [x] Forward CertProvisioner events to SmartProxy’s `'certificate'` listener.
+
+- [x] CertProvisioner lifecycle methods:
+  - [x] `start()`: provision all domains, start scheduler.
+  - [x] `stop()`: stop scheduler.
+  - [x] `requestCertificate(domain)`: on-demand provisioning.
+
+- [x] Handle static certificate auto-refresh:
+  - [x] In the renewal scheduler, for domains with static certs, re-call `certProvider(domain)` near expiry.
+  - [x] Apply returned cert via `networkProxyBridge.applyExternalCertificate()`.
+
+- [ ] Tests:
+  - Unit tests for `CertProvisioner`, mocking Port80Handler and `certProvider`:
+    * Validate initial provisioning and dynamic/static flows.
+    * Validate scheduling triggers correct renewals.
+  - Integration tests:
+    * Use actual in-memory Port80Handler with short intervals to verify renewals and event emission.
+
+- [ ] Documentation:
+  - Add code-level TS doc for `CertProvisioner` API (options, methods, events).
+  - Update root `README.md` and architecture diagrams to show `CertProvisioner` role.
