+# FEATURE CONTRACT — SINGLE SOURCE OF TRUTH (60 FEATURES)
+# ----------------------------------------------------------------------------
+#
+# ENGINEERING NOTE — why this looks the way it does:
+#
+#   Previously the contract was spread across three top-level sets
+#   (REQUIRED_FEATURES, METADATA_FIELDS, BINARY_FEATURES, ...), with no
+#   runtime check that they were mutually consistent. A drift where a
+#   single key ('price') landed in BOTH the "required features" list AND
+#   the "metadata to strip before validating" set caused the validator to
+#   report {'price'} missing on every tick, which silently shut down
+#   publishing for the entire pipeline.
+#
+#   The fix is structural: ONE FeatureContract object owns the full schema
+#   and checks its own invariants at import time. Any future drift crashes
+#   the module on load with a named offender, instead of corrupting the
+#   wire format at 60Hz for hours.
+#
+#   The old module-level names (REQUIRED_FEATURES, METADATA_FIELDS, etc.)
+#   are kept as PROJECTIONS of the contract for call-site back-compat — the
+#   rest of Features.py can import them exactly as before.

+K1RL QUANT - INSTITUTIONAL REWARDS SYSTEM v5.2.1-V75
+HuggingFace Spaces Edition - Maximum Performance
+
+V75 NAMESPACE ISOLATION:
+✅ All channels prefixed with "V75:" — zero cross-talk with other spaces
+✅ Uses DB 0/1 (features/rewards) — isolated per Space container
+✅ Imports from redis_config_v75 for V75-specific configuration
+
+CRITICAL FIX (v5.2.1):
+✅ FIXED: asyncio.get_event_loop() from listener thread returned WRONG loop
+   → Reward tasks silently dropped (never scheduled)
+   → Now stores loop reference via asyncio.get_running_loop() in start()
+✅ All v5.2.0 fixes retained
+
+CRITICAL FIX (v5.2.0):
+✅ REMOVED duplicate RedisAblyClient - uses redis_connection_manager.RedisAblyClient
+✅ Added connection health monitoring with auto-reconnection
+✅ Bounded reward task pool (prevents coroutine leak)
+✅ Deriv WebSocket auto-reconnection loop
+✅ Pub/sub heartbeat detection (detects silent disconnects)
+
+PREVIOUS OPTIMIZATIONS (v5.1.0):
+✅ Proper async price streaming with reconnection
+✅ LRU cache for price data with TTL
+✅ O(1) signal tracking with hash maps
+✅ Batch processing with backpressure
+✅ Connection health monitoring
+✅ Memory-efficient deque buffers
+✅ HuggingFace Spaces compatibility
+✅ Container-safe logging and paths
