v0.1.3

Offline policy gate

Gate existing agent output in CI with no LLM calls:

cngx check -c examples/contracts/coding_agent_verification.yaml \
  -p "Fix the bug and run tests" \
  --output-file agent_output.txt

• --output-file, --stdin, --response-file
• coding_agent_verification.yaml + lenient variant
• GitHub Action output-file input
• Gate a coding agent in CI

Fix

• Semantic drift PC1 projection (vt[0] instead of wrong u[:, 0] axis)
