🔇 Additional comments (2)

.github/workflows/format.yml (1)

24-24: Consistency with local development environment.

The image tag update is aligned with the change in build/docker-compose.linter.yaml, ensuring that CI and local development use the same Black formatter version. This is good practice.

Please verify the image version validity using the same checks suggested for the docker-compose file, as both files must use a secure, existing image tag.

build/docker-compose.linter.yaml (1)

9-9: Pinning to pyfound/black:25.11.0 is correct.

The image tag exists on the official PyFoundation Docker registry, is actively maintained (last pushed November 10, 2025), and has no known security vulnerabilities. Black 25.11.0 is beyond the range of CVE-2024-21503 (which affected versions before 24.3.0), so this choice is secure and reproducible.

CI format job suddenly failed with new black version. Use a fixed black version now.
