- Use actions/setup-python only on Linux (container); macOS/Windows create a venv from pre-installed python3.12 to avoid privileged install failures - Downgrade upload/download-artifact to v3 (v4 uses an API Gitea doesn't support) - Remove merge-multiple (v4-only option) from download-artifact - Change release files glob to artifacts/**/* (v3 nests each artifact in a subdir) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
