What changed. Why it matters.

   Alert delivery fix + expanded marketing

   • Fix

     Alert notifications now persist with correct user_id — Windows toasts fire reliably after price alerts trigger.

   • Fix

     Alert SSE stream now uses absolute __API_BASE__ URL — works correctly inside the Tauri webview origin.

   Market Making v3 polish

   • Improved

     Auto-tuner adjusts γ and κ over a 30-minute rolling window.

   • Improved

     Momentum detector suppresses aggressive buys for 60s after a sell — reduces buy-into-dump incidents.

   • New

   • New

     VolatilityTracker scales spreads by √variance — quiet pairs get tight quotes, volatile pairs get safe ones.

   LIMIT_MAKER post-only & fee floor

   • New

     All market making orders now use LIMIT_MAKER — unlocks the 0.075% maker fee on Binance.

   • New

     Fee floor introduced: `makerFee × 2 × 1.2` — sells never price below round-trip cost.

   • Improved
