From bbd3f49ce53a4403530c63692e94e080ba92d96d Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Mon, 6 Apr 2026 04:03:22 +0000 Subject: [PATCH] feat: add protocol mirror engine for Xray-core auto-update MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds server/proxy/service/protocol-mirror.js — the Protocol Mirror Engine that monitors Xray-core releases and manages automatic updates with: - GitHub API polling (every 6h) with result caching - Installed vs latest version comparison - TLS/Reality fingerprint consistency checks - LLM-powered update risk analysis via llm-router.js - Safe auto-update: download → backup → install → verify → restart - Failure protection: 3 consecutive failures triggers admin alert - Update summary generation for email-hub distribution - State persistence to data/protocol-mirror-status.json Runs as a PM2-managed service checking every 30 minutes.
