# CTO Eval Fixtures

This directory defines the deterministic fixture contracts for the CTO WebUI
promotion suite.

The fixture layer has two gates:

- `run-promotion-suite.py` validates that every PRD-required eval has a prompt,
  required evidence, required CTO events, and safety gates.
- `run-promotion-fixtures.py` executes the fixture matrix in isolated local
  state and writes event/evidence artifacts under `cto/evals/artifacts/`.

These gates do not claim Codex comparative parity or live LLM task solving.
