-#  PHOENIX FURY API v3.0 - UNIFIED L4/L7 HIGH-PERFORMANCE EDITION
+#  PHOENIX FURY API v4.0 - TITAN CLASS
 #
-#  - UNIFIED: Combines high-PPS Layer 4 raw socket attacks (TCP/UDP) with
-#    high-RPS Layer 7 HTTP attacks in a single powerful API.
-#  - MAXIMUM PERFORMANCE: Utilizes a multiprocessing.Manager for state and
-#    a lock-protected shared memory counter for near-zero overhead statistics.
-#  - AIOHTTP FIX: Corrected TCPConnector for compatibility with modern versions.
-#  - PRIVILEGE AWARE: Automatically detects root/admin rights and enables
-#    L4 capabilities accordingly.
+#  - RE-ARCHITECTED: Employs a thread-safe Singleton AttackManager to completely
+#    eliminate race conditions and ensure stable, consecutive attacks.
+#  - RELIABLE LIFECYCLE: Correctly uses FastAPI's BackgroundTasks for the
+#    entire attack lifecycle (start -> wait -> stop), guaranteeing accurate durations.
+#  - HTTPS/SSL SUPPORT: L7 worker now intelligently detects secure ports (443)
+#    and automatically uses HTTPS, fixing the critical bug of no requests on SSL.
+#  - MAXIMUM PERFORMANCE: Retains the high-speed shared memory counter and
+#    uvloop event loop for state-of-the-art PPS/RPS throughput.
+#  - RESILIENT & ROBUST: Enhanced process cleanup, clearer logging, and a
+#    state machine that prevents any overlap between attack runs.
 #
-#  *** DESIGNED FOR AUTHORIZED, HIGH-THROUGHPUT STRESS TESTING ***
+#  *** The definitive, stable, and most powerful version. ***
