"""
AIVA Simulation Engine - Synthetic Task Generation and Dry-Run Testing
========================================================================

Generates synthetic tasks and runs them through AIVA's decision gate as
dry-runs to rapidly build the proof-of-work decision matrix without
real-world risk.

This component accelerates autonomy calibration by simulating hundreds
of decision scenarios across all autonomy levels and task categories.

Features:
  - 180+ task templates (60 base tasks × 3 variants each)
  - Even distribution across all 4 autonomy levels
  - Normal, edge case, and high-risk variants
  - Batch generation with randomization
  - Dry-run simulation through DecisionGate
  - Accuracy metrics and calibration reports
  - Integration with OutcomeTracker for learning
