[1.20.3] - 2025-12-03

• FIXED: Discovery false positives - now detects mid-transfer DPI blocking (throttling, stalls, resource blocking) instead of trusting initial HTTP 200.
• ADDED: Discovery network baseline - measures reference domain speed first, requires target to achieve 4KB+ downloaded at 30%+ of baseline speed. Configurable reference domain in Settings → Discovery (default: yandex.ru).
• ADDED: Discovery binary search optimization for TTL and fragmentation position parameters - reduces Phase 2 tests from ~50 to ~15 while finding optimal values. Uses fingerprint hints when available.
• IMPROVED: Sets editor save button now shows immediate loading feedback with spinner and disabled state to prevent double-submit during slow saves.
• IMPROVED: Sets manager now supports drag-and-drop reordering instead of up/down arrows.
