⚡ 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 (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 — OpenWrt's native, high-performance C scripting language — delivering instant response times with minimal RAM footprint (starting from 128 MB RAM devices).

🌐 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. Zapret v1 (nfqws): Basic TCP/UDP packet desynchronization (fake, disorder, split2) directly on router without VPS.
3. Zapret v2 (nfqws2): Advanced multi-vector DPI evasion (multisplit, seqovl, wsize) for YouTube 4K and Discord.
4. ByeDPI (ciadpi): Local SOCKS5 desync engine with HTTP/TLS SNI payload fragmentation.
5. Encrypted Proxy Tunnel (sing-box): Censored endpoints and private traffic are routed through modern protocols (VLESS Reality, Hysteria2, WireGuard).

🔥 Core Features & Subsystems

🛡️ 1. Multi-Protocol Proxying & Local DPI Bypass

• sing-box Engine (v1.11+): Native support for modern proxy protocols — 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.
• 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.

🌐 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.

🤖 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.
• 🩺 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.
• 🚨 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.

📱 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 <code_name>, /restart, /backup, /status.

🛡️ 4. Watchdog — Protection & Self-Healing System

Watchdog is the heart of Tachyon's stability, running every 5–15 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.

🖥️ 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.
