-#  PHOENIX FURY API v4.0 - TITAN CLASS
+#  PHOENIX FURY API v5.0 - COLOSSUS EDITION
 #
-#  - 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.
+#  - HYPER-STABLE CONNECTION HANDLING: The L7 worker now forces a new connection
+#    per request. This is the critical fix for SSL/TLS errors under heavy load
+#    against defended targets, preventing worker crashes and ensuring max RPS.
+#  - ADVANCED SSL CONTEXT: Implements a proper, explicit SSL context for the
+#    most reliable handling of HTTPS targets.
+#  - PERFORMANCE GUIDANCE: The API now provides warnings and validation for
+#    process counts, guiding the user towards optimal settings for their hardware
+#    to prevent CPU thrashing and achieve true maximum throughput.
+#  - ARCHITECTURALLY SOUND: Built upon the resilient Singleton Manager and
+#    FastAPI BackgroundTasks from v4.0 for a rock-solid foundation.
