"""
Live Amazon Bedrock Invariant Testing Runner (v2.3)
===================================================
Connects Bartholomew Tier-0 Fast Path Gate directly to Amazon Bedrock Runtime
(Claude 3.5 Sonnet / Claude 3 Haiku / Amazon Titan).

Features:
  1. Live or Staged Bedrock converse() and invoke_model() gating.
  2. Sub-50 µs polyglot AST pre-flight evaluation on toolUse blocks.
  3. Automated secret scrubber and Ed25519 Merkle receipt minting.
  4. FinOps latency and token cost analysis report.

Usage:
  python scripts/test_live_aws_bedrock.py
