# Cross-platform CI for the OpenAI Codex chat-provider work (PR #5724).
#
# The main studio-backend-ci.yml runs the full backend test suite on
# ubuntu-latest across Python 3.10/3.11/3.12/3.13, which already
# exercises tests/test_codex_provider.py. This file adds Codex-only
# matrix runs on macos-14 (Apple Silicon, MLX-relevant for Studio
# users) and windows-latest (Studio ships a Windows desktop build)
# so the codex_bin / sys.modules / importlib gates that Codex relies
# on are validated on all three platforms with a small (~1 min)
# cycle time. Paths filter keeps it from re-running on unrelated
# code changes.
