## 2025-03-18 - 4.2.3 - fix(connectionhandler)
Remove unnecessary delay in TLS session ticket handling for connections without SNI
- Eliminated the extra setTimeout waiting period before cleaning up connections flagged as session_ticket_blocked_no_sni
- Ensures immediate cleanup and improves connection responsiveness during TLS handshake failures
## 2025-03-18 - 4.2.2 - fix(connectionhandler)
Ensure proper termination of TLS connections without SNI by explicitly ending the socket after sending the unrecognized_name alert. This prevents the connection from hanging and avoids potential duplicate handling.
- Added socket.end() after uncorking the alert packet in ClientHello handling to force connection closure.
- Prevents duplicate data events and ensures the warning alert is processed by clients like Chrome.
## 2025-03-17 - 4.2.1 - fix(core)
No uncommitted changes detected in the project.
## 2025-03-17 - 4.2.0 - feat(tlsalert)
add sendForceSniSequence and sendFatalAndClose helper functions to TlsAlert for improved SNI enforcement
- Introduce sendForceSniSequence to combine multiple alerts and force clients to provide SNI
- Add sendFatalAndClose to immediately send a fatal alert and close the connection
- Enhance TLS alert handling for better browser compatibility and error management
## 2025-03-17 - 4.1.16 - fix(tls)
Improve TLS alert handling in connection handler: use the new TlsAlert class to send proper unrecognized_name alerts when a ClientHello is missing SNI and wait for a retry on the same connection before closing. Also, add alertFallbackTimeout tracking to connection records for better timeout management.
- Replaced hardcoded alert buffers in ConnectionHandler with calls to the TlsAlert class.
- Removed old warnings and implemented a mechanism to remove existing 'data' listeners and await a new ClientHello.
- Introduced alertFallbackTimeout property in connection records to track fallback timeout and ensure proper cleanup.
- Extended the delay before closing the connection after sending an alert, providing the client more time to retry.
## 2025-03-17 - 4.1.15 - fix(connectionhandler)
Delay socket termination in TLS session resumption handling to allow proper alert processing
- Removed the immediate socket.end() call in finishConnection and moved it inside the setTimeout, ensuring that clients (especially Chrome) have additional time to process the TLS alert before connection termination
- This prevents premature socket closure on ClientHello without SNI when session tickets are disallowed
## 2025-03-17 - 4.1.14 - fix(ConnectionHandler)
Use the correct TLS alert data and increase the delay before socket termination when session resumption without SNI is detected.
- Replaced certificateExpiredAlert with serverNameUnknownAlertData for sending the appropriate alert.
- Increased the cleanup delay from 1000ms to 5000ms to allow a more graceful termination.
## 2025-03-17 - 4.1.13 - fix(tls-handshake)
Set certificate_expired TLS alert level to warning instead of fatal to allow graceful termination.
- In the TLS handshake alert for certificate_expired (0x2F), changed the alert level from 0x02 (fatal) to 0x01 (warning).
- This change avoids abrupt connection termination, enabling a smoother handling of certificate expiration alerts.
## 2025-03-17 - 4.1.12 - fix(classes.pp.connectionhandler)
Replace unrecognized_name alert data with certificate_expired alert in TLS handshake handling for session resumption without SNI
- Switched the alert payload from serverNameUnknownAlertData to a new certificateExpiredAlert buffer
- Now sends a fatal certificate_expired alert (code 47) instead of a warning unrecognized_name alert
- Improves TLS error reporting and encourages immediate disconnection when a ClientHello lacks SNI and session tickets are disallowed
## 2025-03-17 - 4.1.11 - fix(connectionhandler)
Increase delay before cleaning up connections when session resumption is blocked due to missing SNI, allowing more natural socket termination.
- Changed cleanup delay in ts/classes.pp.connectionhandler.ts from 300ms to 1000ms.
- This fix ensures that sockets get sufficient time to terminate gracefully.
## 2025-03-16 - 4.1.10 - fix(connectionhandler)
Increase delay timings for TLS alert transmission in session ticket blocking to allow graceful socket termination
- Updated finishConnection: replaced immediate socket.destroy with a graceful end call
- Increased delay after successful write from 50ms to 200ms to allow alert processing
- Raised safety timeout from 250ms to 400ms when waiting for 'drain' event
## 2025-03-16 - 4.1.9 - fix(ConnectionHandler)
Replace closeNotify alert with handshake failure alert in TLS ClientHello handling to properly signal missing SNI and enforce session ticket restrictions.
- Switched alert data sent on missing SNI from closeNotifyAlert to sslHandshakeFailureAlertData.
- Ensures consistent TLS alert behavior during handshake failure.
## 2025-03-16 - 4.1.8 - fix(ConnectionHandler/tls)
Change the TLS alert sent when a ClientHello lacks SNI: use the close_notify alert instead of handshake_failure to prompt immediate retry with SNI.
- Replaced the previously sent handshake_failure alert (code 0x28) with a close_notify alert (code 0x00) in the TLS session resumption handling in ConnectionHandler.
- This change encourages clients to immediately retry and include SNI when allowSessionTicket is false.
## 2025-03-16 - 4.1.7 - fix(classes.pp.connectionhandler)
Improve TLS alert handling in ClientHello when SNI is missing and session tickets are disallowed
- Replace the unrecognized_name alert with a handshake_failure alert to ensure better client behavior.
- Refactor the alert sending mechanism using cork/uncork and add a safety timeout for the drain event.
- Enhance logging for debugging TLS handshake failures when SNI is absent.
## 2025-03-16 - 4.1.6 - fix(tls)
Refine TLS ClientHello handling when allowSessionTicket is false by replacing extensive alert timeout logic with a concise warning alert and short delay, encouraging immediate client retry with proper SNI
- Update the TLS alert sending mechanism to use cork/uncork and a short, fixed delay instead of long timeouts
- Remove redundant event listeners and excessive cleanup logic after sending the alert
- Improve code clarity and encourage clients (e.g., Chrome) to retry handshake with SNI more responsively
## 2025-03-16 - 4.1.5 - fix(TLS/ConnectionHandler)
Improve handling of TLS session resumption without SNI by sending an 'unrecognized_name' alert instead of immediately terminating the connection. This change adds a grace period for the client to retry the handshake with proper SNI and cleans up the connection if no valid response is received.
- Send a TLS warning (unrecognized_name alert, code 112) when a ClientHello is received without SNI and session tickets are disallowed.
- Utilize socket cork/uncork to ensure the alert is sent as a single packet.
- Add a 5-second alert timeout and a subsequent 30-second grace period to allow clients to initiate a new handshake with SNI.
- Clean up and terminate the connection if no valid SNI is provided after the grace period, logging appropriate termination reasons.
## 2025-03-15 - 4.1.4 - fix(ConnectionHandler)
Refactor ConnectionHandler code formatting for improved readability and consistency in log messages and whitespace handling
- Standardized indentation and spacing in method signatures and log statements
- Aligned inline comments and string concatenations for clarity
- Minor refactoring of parameter formatting without changing functionality
## 2025-03-15 - 4.1.3 - fix(connectionhandler)
Improve handling of TLS ClientHello messages when allowSessionTicket is disabled and no SNI is provided by sending a warning alert (unrecognized_name, code 0x70) with a proper callback and delay to ensure the alert is transmitted before closing the connection.
- Replace the fatal alert (0x02/0x40) with a warning alert (0x01/0x70) to notify clients to send SNI.
- Use socket.write callback to wait 100ms after sending the alert before terminating the connection.
- Remove the previous short (50ms) delay in favor of a more reliable delay mechanism before cleanup.
## 2025-03-15 - 4.1.2 - fix(connectionhandler)
Send proper TLS alert before terminating connections when SNI is missing and session tickets are disallowed.
- Added logic to transmit a fatal TLS alert (Handshake Failure) before closing the connection when no SNI is present with allowSessionTicket=false.
- Introduced a slight 50ms delay after sending the alert to ensure the client receives the alert properly.
- Applied these changes both for the initial ClientHello and when handling subsequent TLS data.
## 2025-03-15 - 4.1.1 - fix(tls)
Enforce strict SNI handling in TLS connections by terminating ClientHello messages lacking SNI when session tickets are disallowed and removing legacy session cache code.
- In classes.pp.connectionhandler.ts, if allowSessionTicket is false and no SNI is extracted from a ClientHello, the connection is terminated to force a new handshake with SNI.
- In classes.pp.snihandler.ts, removed session cache and related cleanup functions used for tab reactivation, simplifying SNI extraction logic.
- Improved logging in TLS processing to aid in diagnosing handshake and session resumption issues.
## 2025-03-14 - 4.1.0 - feat(SniHandler)
Enhance SNI extraction to support session caching and tab reactivation by adding session cache initialization, cleanup and helper methods. Update processTlsPacket to use cached SNI for session resumption and connection racing scenarios.
- Introduce initSessionCacheCleanup, cleanupSessionCache, createClientKey, cacheSession, and getCachedSession methods to manage SNI information.
- Cache SNI based on client IP and client random to improve handling of fragmented ClientHello messages and tab reactivation.
- Update processTlsPacket to leverage cached SNI when standard extraction fails, reducing redundant extraction and enhancing connection racing behavior.
## 2025-03-14 - 4.0.0 - BREAKING CHANGE(core)
refactor: reorganize internal module structure to use 'classes.pp.*' modules
- Renamed port proxy and SNI handler source files to 'classes.pp.portproxy.js' and 'classes.pp.snihandler.js' respectively
- Updated import paths in index.ts and test files (e.g. in test.ts and test.router.ts) to reference the new file names
- This refactor improves code organization but breaks direct imports from the old paths
- Renamed 'ts/classes.portproxy.ts' to 'ts/classes.pp.portproxy.ts'
- Renamed 'ts/classes.snihandler.ts' to 'ts/classes.pp.snihandler.ts'
- Updated exports in index.ts to export from 'classes.pp.portproxy.js' and 'classes.pp.snihandler.js'
- Updated test files to import modules from new paths
## 2025-03-12 - 3.41.8 - fix(portproxy)
Improve TLS handshake timeout handling and connection piping in PortProxy
- Increase the default initial handshake timeout from 60 seconds to 120 seconds
- Add a 30-second grace period before terminating connections waiting for initial TLS data
- Refactor piping logic by removing redundant callback and establishing piping immediately after flushing buffered data
- Enhance debug logging during TLS ClientHello processing for improved SNI extraction insights
## 2025-03-12 - 3.41.7 - fix(core)
Refactor PortProxy and SniHandler: improve configuration handling, logging, and whitespace consistency
- Standardized indentation and spacing for configuration properties in PortProxy settings (e.g. ACME options, keepAliveProbes, allowSessionTicket)
- Simplified conditional formatting and improved inline comments in PortProxy
- Enhanced logging messages in SniHandler for TLS handshake and session resumption detection
- Improved debugging output (e.g. hexdump of initial TLS packet) and consistency of multi-line expressions
## 2025-03-12 - 3.41.6 - fix(SniHandler)
Refactor SniHandler: update whitespace, comment formatting, and consistent type definitions
- Unified inline comment style and spacing in SniHandler
- Refactored session cache type declaration for clarity
- Adjusted buffer length calculations to include TLS record header consistently
- Minor improvements to logging messages during ClientHello reassembly and SNI extraction
## 2025-03-12 - 3.41.5 - fix(portproxy)
Enforce TLS handshake and SNI validation on port 443 by blocking non-TLS connections and terminating session resumption attempts without SNI when allowSessionTicket is disabled.
- Added explicit check to block non-TLS connections on port 443 to ensure proper TLS usage.
- Enhanced logging for TLS ClientHello to include details on SNI extraction and session resumption status.
- Terminate connections with missing SNI by setting termination reasons ('session_ticket_blocked' or 'no_sni_blocked').
- Ensured consistent rejection of non-TLS handshakes on standard HTTPS port.
## 2025-03-12 - 3.41.4 - fix(tls/sni)
Improve logging for TLS session resumption by extracting and logging SNI values from ClientHello messages.
- Added logging to output the extracted SNI value during renegotiation, initial ClientHello and in the SNI handler.
- Enhanced error handling during SNI extraction to aid troubleshooting of TLS session resumption issues.
## 2025-03-12 - 3.41.3 - fix(TLS/SNI)
Improve TLS session resumption handling and logging. Now, session resumption attempts are always logged with details, and connections without a proper SNI are rejected when allowSessionTicket is disabled. In addition, empty SNI extensions are explicitly treated as missing, ensuring stricter and more consistent TLS handshake validation.
- Always log session resumption in both renegotiation and initial ClientHello processing.
- Terminate connections that attempt session resumption without SNI when allowSessionTicket is false.
- Treat empty SNI extensions as absence of SNI to improve consistency in TLS handshake processing.
## 2025-03-11 - 3.41.2 - fix(SniHandler)
Refactor hasSessionResumption to return detailed session resumption info
- Changed the return type of hasSessionResumption from boolean to an object with properties isResumption and hasSNI
- Updated early return conditions to return { isResumption: false, hasSNI: false } when buffer is too short or invalid
- Modified corresponding documentation to reflect the new return type
## 2025-03-11 - 3.41.1 - fix(SniHandler)
Improve TLS SNI session resumption handling: connections containing a session ticket are now only rejected when no SNI is present and allowSessionTicket is disabled. Updated return values and logging for clearer resumption detection.
- Changed SniHandler.hasSessionResumption to return an object with 'isResumption' and 'hasSNI' flags.
- Adjusted PortProxy logic to only terminate connections when a session ticket is detected without an accompanying SNI (when allowSessionTicket is false).
- Enhanced debug logging to clearly differentiate between session resumption scenarios with and without SNI.
## 2025-03-11 - 3.41.0 - feat(PortProxy/TLS)
Add allowSessionTicket option to control TLS session ticket handling

# 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.

fromPort: { from: 3000, to: 3010 }, // Forward ports 3000-3010
toPort: { from: 8000, to: 8010 }, // To ports 8000-8010
protocol: 'tcp', // TCP protocol (default)
ipv6Support: true, // Enable IPv6 support
enableLogging: true // Enable detailed logging
});
// Multiple port specifications with IP filtering
const advancedProxy = new IPTablesProxy({
fromPort: [80, 443, { from: 8000, to: 8010 }], // Multiple ports/ranges
toPort: [8080, 8443, { from: 18000, to: 18010 }],
allowedSourceIPs: ['10.0.0.0/8', '192.168.1.0/24'], // Only allow these IPs

const sslProxy = new IPTablesProxy({
fromPort: 443,
toPort: 8443,
netProxyIntegration: {
enabled: true,
redirectLocalhost: true, // Redirect localhost traffic to NetworkProxy
sslTerminationPort: 8443 // Port where NetworkProxy handles SSL
}
});
// Start any of the proxies
await basicProxy.start();
```
### Automatic HTTPS Certificate Management
```typescript
import { Port80Handler } from '@push.rocks/smartproxy';

## Advanced Features
### TLS Handshake Optimization
The enhanced `PortProxy` implementation includes significant improvements for TLS handshake handling:
- Robust SNI extraction with improved error handling
- Increased buffer size for complex TLS handshakes (10MB)
- Longer initial handshake timeout (60 seconds)
- Detection and tracking of TLS connection states
- Optional detailed TLS debug logging for troubleshooting
- Browser compatibility fixes for Chrome certificate errors
```typescript
// Example configuration to solve Chrome certificate errors
const portProxy = new PortProxy({
// ... other settings
initialDataTimeout: 60000, // Give browser more time for handshake
maxPendingDataSize: 10 * 1024 * 1024, // Larger buffer for complex handshakes
enableTlsDebugLogging: true, // Enable when troubleshooting
});
```
### Connection Management and Monitoring
The `PortProxy` class includes built-in connection tracking and monitoring:
- Automatic cleanup of idle connections with configurable timeouts
- Timeouts for connections that exceed maximum lifetime
- Detailed logging of connection states
- Termination statistics
- Randomized timeouts to prevent "thundering herd" problems
- Per-domain timeout configuration
### WebSocket Support
The `NetworkProxy` class provides WebSocket support with:
- WebSocket connection proxying
- Automatic heartbeat monitoring
- Connection cleanup for inactive WebSockets
### SNI-based Routing
The `PortProxy` class can inspect the SNI (Server Name Indication) field in TLS handshakes to route connections based on the requested domain:
- Multiple backend targets per domain
- Round-robin load balancing
- Domain-specific allowed IP ranges
- Protection against SNI renegotiation attacks
### Enhanced IPTables Management
The improved `IPTablesProxy` class offers advanced capabilities:
- Support for multiple port ranges and individual ports
- IPv6 support with ip6tables
- Source IP filtering with allow/block lists
- Custom chain creation for better rule organization
- NetworkProxy integration for SSL termination
- Automatic rule existence checking to prevent duplicates
- Comprehensive cleanup on shutdown
### SmartProxy (IPortProxySettings)
- `fromPort`, `toPort` (number)
- `domainConfigs` (IDomainConfig[])
- `sniEnabled`, `defaultAllowedIPs`, `preserveSourceIP` (booleans)
- Timeouts: `initialDataTimeout`, `socketTimeout`, `inactivityTimeout`, etc.
- Socket opts: `noDelay`, `keepAlive`, `enableKeepAliveProbes`
- `acme` (IAcmeOptions), `certProvider` (callback)
- `useNetworkProxy` (number[]), `networkProxyPort` (number)
## Troubleshooting
### Browser Certificate Errors
### NetworkProxy
- Verify ports, certificates and `rejectUnauthorized` for TLS errors
- Configure CORS or use `addDefaultHeaders` for preflight issues
- Increase `maxConnections` or `connectionPoolSize` under load
If you experience certificate errors in browsers, especially in Chrome, try these solutions:
### Port80Handler
- Run as root or grant CAP_NET_BIND_SERVICE for port 80
- Inspect `certificate-failed` events and switch staging/production
1. **Increase Initial Data Timeout**: Set `initialDataTimeout` to 60 seconds or higher
2. **Increase Buffer Size**: Set `maxPendingDataSize` to 10MB or higher
3. **Enable TLS Debug Logging**: Set `enableTlsDebugLogging: true` to troubleshoot handshake issues
4. **Enable Keep-Alive Probes**: Set `enableKeepAliveProbes: true` for better connection stability
5. **Check Certificate Chain**: Ensure your certificate chain is complete and in the correct order
### NfTablesProxy
- Ensure `nft` is installed and run with sufficient privileges
- Use `forceCleanSlate:true` to clear conflicting rules
```typescript
// Configuration to fix Chrome certificate errors
const portProxy = new PortProxy({
// ... other settings
initialDataTimeout: 60000,
maxPendingDataSize: 10 * 1024 * 1024,
enableTlsDebugLogging: true,
enableKeepAliveProbes: true
});
```
### Redirect / SslRedirect
- Check `fromHost`/`fromPath` patterns and Host headers
- Validate `sslOptions` key/cert correctness
### Connection Stability
For improved connection stability in high-traffic environments:
1. **Set Appropriate Timeouts**: Use longer timeouts for long-lived connections
2. **Use Domain-Specific Timeouts**: Configure per-domain timeouts for different types of services
3. **Enable TCP Keep-Alive**: Ensure `keepAlive` is set to `true`
4. **Monitor Connection Statistics**: Enable detailed logging to track termination reasons
5. **Fine-tune Inactivity Checks**: Adjust `inactivityCheckInterval` based on your traffic patterns
### IPTables Troubleshooting
If you're experiencing issues with IPTablesProxy:
1. **Enable Detailed Logging**: Set `enableLogging: true` to see all rule operations
2. **Force Clean Slate**: Use `forceCleanSlate: true` to remove any lingering rules
3. **Use Custom Chains**: Enable `addJumpRule: true` for cleaner rule management
4. **Check Permissions**: Ensure your process has sufficient permissions to modify iptables
5. **Verify IPv6 Support**: If using `ipv6Support: true`, ensure ip6tables is available
### SmartProxy & SniHandler
- Increase `initialDataTimeout`/`maxPendingDataSize` for large ClientHello
- Enable `enableTlsDebugLogging` to trace handshake
- Ensure `allowSessionTicket` and fragmentation support for resumption

# Project Simplification Plan
This document outlines a roadmap to simplify and refactor the SmartProxy & NetworkProxy codebase for better maintainability, reduced duplication, and clearer configuration.
## Goals
- Eliminate duplicate code and shared types
- Unify certificate management flow across components
- Simplify configuration schemas and option handling
- Centralize plugin imports and module interfaces
- Strengthen type safety and linting
- Improve test coverage and CI integration
## Plan
- [x] Extract all shared interfaces and types (e.g., certificate, proxy, domain configs) into a common `ts/common` module
- [x] Consolidate ACME/Port80Handler logic:
- [x] Merge standalone Port80Handler into a single certificate service
- [x] Remove duplicate ACME setup in SmartProxy and NetworkProxy
- [x] Unify configuration options:
- [x] Merge `INetworkProxyOptions.acme`, `IPort80HandlerOptions`, and `port80HandlerConfig` into one schema
- [x] Deprecate old option names and provide clear upgrade path
- [x] Centralize plugin imports in `ts/plugins.ts` and update all modules to use it
- [x] Remove legacy or unused code paths (e.g., old HTTP/2 fallback logic if obsolete)
- [ ] Enhance and expand test coverage:
- Add unit tests for certificate issuance, renewal, and error handling
- Add integration tests for HTTP challenge routing and request forwarding
- [ ] Update main README.md with architecture overview and configuration guide
- [ ] Review and prune external dependencies no longer needed
Once these steps are complete, the project will be cleaner, easier to understand, and simpler to extend.
