## β‘ About Tachyon
**Tachyon** is an advanced, autonomous network routing, proxy orchestration, and anti-censorship engine designed specifically for **OpenWrt** routers (fully supporting **OpenWrt 23.05, 24.10, 25.x, and SNAPSHOT** builds). Direct fork of **[Forkop by @ushan0v](https://github.com/ushan0v/forkop)** (formerly **Podkop Plus**).
Tachyon combines the power of **sing-box**, local hardware DPI bypass engines (**Zapret v1 / Zapret v2 / ByeDPI**), an interactive **Telegram bot**, and a cutting-edge **AI Stack** (autonomous **AI Doctor v2.5** with offline local diagnostics & **HTTP REST Agent API / OpenAPI 3.0**).
The entire backend logic is written in **ucode** β OpenWrt's native, high-performance C scripting language β delivering instant response times with minimal RAM footprint (starting from 128 MB RAM devices).
---
## π Architecture & Traffic Pipeline
Tachyon intercepts network flows via kernel **nftables** and dispatches requests without unnecessary latency:
1. **Direct WAN**: Local services, national banks, and trusted destinations proceed without proxy overhead (`0 ms overhead`).
2. **Local DPI Desync (Zapret v2 / ByeDPI)**: YouTube 4K, Discord, and target websites are desynchronized directly on the router without requiring a VPS.
3. **Encrypted Proxy Tunnel (sing-box)**: Censored endpoints and private traffic are routed through modern protocols (VLESS Reality, Hysteria2, WireGuard).
---
## π₯ Core Features & Subsystems
### π‘οΈ 1. Multi-Protocol Proxying & Local DPI Bypass
* **sing-box Engine (v1.11+)**: Native support for modern proxy protocols β **VLESS (Reality / gRPC / WS)**, **VMess**, **Shadowsocks**, **Trojan**, **Hysteria2**, and **WireGuard / AmneziaWG**.
* **Local DPI Bypass Without External VPS**:
* Full built-in integration with **Zapret v1 (`nfqws`)**, **Zapret v2 (`nfqws2`)**, and **ByeDPI (`ciadpi`)** desync engines for hardware TCP segment manipulation (`fake`, `disorder`, `split2`, `multisplit`, `seqovl`, `wsize`).
* **Multi-Dimensional Selective Routing**:
* **By Domains & IP Subnets**: Route only target traffic through proxies or desync engines.
* **By Client Devices (MAC / IP)**: Per-device routing rules for Smart TVs, smartphones, PCs, and gaming consoles.
* **By GeoIP & Countries**: Flexible inclusion/exclusion list controls based on destination country.
* **Automated Subscription Updates**: Background fetching, parsing, and node rotation from remote subscription URLs with automated latency (RTT) testing.
#### π Hosts Sections & DNS Overrides (Hosts Engine)
* **Static DNS Overriding (`dns_hosts`)**: Direct mapping of domains to static IP addresses in sing-box DNS and dnsmasq without editing `/etc/hosts`.
* **Remote Hosts Lists Ingestion (`hosts_list_urls`)**: Automatic background downloading and parsing of external host lists and blocklists (AdAway, StevenBlack, custom blocklists).
* **Unified Cache (`combined.txt`)**: High-performance deduplication, merging, and global caching of multiple remote host sources into a single lightweight cache.
* **GitHub Mirror Failover**: Resilient downloads that automatically retry via mirrors (`gh-proxy.com`, `ghproxy.net`) if direct access to github.com is blocked or throttled.
* **Hosts-Only Action Sections (`action = hosts`)**: Dedicated routing sections operating purely as DNS override engines without requiring an outbound proxy association.
---
### π€ 2. AI Doctor & HTTP REST Agent API (AI Stack v2.5)
* **Tachyon AI Doctor (v2.5)**: Deep AI diagnostic engine supporting modern LLMs (**OpenAI**, **Anthropic Claude**, **DeepSeek**, or local models via OpenRouter / Ollama).
* **Deep Contextual Intelligence**: Feeds real-time service health, Watchdog failure history (OOM events, error streaks), and compressed system logs into the LLM prompt.
* **Multi-Fix Execution Chains**: Generates multi-action repair sequences with dedicated UI buttons per fix or a single "Fix All" action.
* **π©Ί Offline Local Rule Doctor**:
* **13 Built-in Quick Fix Codes**: Automated repairs for sing-box, nftables, dnsmasq, resolv.conf, DNS cache clearing, subscription refreshing, and network stack restarts.
* **NTP Time Synchronization (`fix_system_time`)**: Automatic detection and recovery from system clock desync.
* **Conntrack Table Flush (`flush_conntrack`)**: Clears connection tracking tables during network storms.
* **DNS Dead-lock Repair (`fix_bootstrap_dns`)**: Prevents circular deadlock on sing-box primary bootstrap resolvers.
* **Tunnel MTU Optimization (`optimize_mtu`)**: Automatic MTU tuning for WireGuard / AmneziaWG tunnels.
* **π¨ Emergency Native Internet Fallback**:
* Instant 1-click restore of clean WAN internet via UI or `tachyon restore_native_internet` CLI command without rebooting the router.
* **π HTTP REST Agent API & OpenAPI 3.0 (Swagger)**:
* Full-featured API at `/cgi-bin/tachyon-agent/` with granular Bearer token security (`agent_api_token`).
* Native **OpenAPI 3.0.3** spec (`GET /cgi-bin/tachyon-agent/openapi.json`) for seamless integration with **ChatGPT Custom GPTs**, N8N, Dify, Flowise, and autonomous LLM agents (Cursor, AutoGPT, Claude Code).
---
### π± 3. Interactive Telegram Control Bot
A feature-rich control center right inside your messenger:
* **Live Rule Management**: View active routing lists and instantly add new domains or IP subnets on the fly.
* **Instant Toggle**: Enable or disable routing sections with a single button.
* **Server Selection & Latency**: Switch active proxy nodes with live RTT ping measurements.
* **Device Access Control**: View active DHCP clients and block/unblock internet access by MAC address.
* **Diagnostics & Commands**: `/doctor`, `/ai_doctor`, `/fix `, `/restart`, `/backup`, `/status`.
---
### π‘οΈ 4. Watchdog β Protection & Self-Healing System
Watchdog is the heart of Tachyon's stability, running every 5β15 seconds without external dependencies:
* **Atomic Operations & UCI Backups**: Configuration writes via `tmp` + `mv` prevent file corruption during sudden power losses.
* **Restart-Loop Protection**: Maximum 3 restarts per 10 minutes (`safe_proxy_restart()`), `PROXY_RESTART_LOCK` mutex, and DNS query loop cooldowns.
* **Memory Optimization (OOM Watchdog)**: Dynamic `GOMEMLIMIT` adjustment under memory pressure with automated Telegram alerts.
* **Seamless Hot-Reload**: Rule updates and server switches apply softly without dropping active TCP connections (Discord calls, gaming, and downloads remain uninterrupted).
* **WAN & Gateway Recovery**: Active interface monitoring and automated route recovery during ISP outages.
---
### π₯οΈ 5. Modern Web Interface (LuCI - TypeScript)
* Native integration into OpenWrt's LuCI dashboard.
* **Interactive Dashboard**: Real-time latency tracking, subscription manager, rule editor, and service controls in a few clicks.
* **Streaming Terminal Modal**: Real-time console logs for component installations and updates without UI freezes.
* **Dynamic Repository Links**: Component cards link directly to the installed variant's GitHub repository (extended, lx, stable).
* **Commit-Level Update Tracking**: Alerts for newer commits within the same release tag.
