Use whenever an NPA container image is built, tagged, pushed, copied, or promoted, including public full-SHA development builds, release publication, build scripts, and image-producing GitHub Actions workflows. Enforce mandatory safety gates and refuse insecure or restricted publication.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Secure Image Build Treat every official development push as public and irreversible. Use one official namespace: `ghcr.io/nebius/nebius-physical-ai/<image>`. Tag reviewed development bytes `dev-<full-git-sha>` and promote only that exact digest to the supported release tag. ## Load The Governing Procedures Read and follow these before acting; do not duplicate their detailed commands: - `skills/atomic/solution-licensing/SKILL.md` - `skills/atomic/build-and-push-image/SKILL.md` - `skills/workflows/contribute-workbench-image/SKILL.md` - `skills/atomic/third-party-eula-preflight/SKILL.md` - `skills/atomic/testing-conventions/SKILL.md` - `docs/workbench/container-packaging.md` For live validation also load `skills/atomic/gpu-selection/SKILL.md`, `skills/atomic/submit-workflow/SKILL.md`, and `skills/atomic/protect-nebius-infra-details/SKILL.md`. ## Mandatory Sequence 1. Resolve the exact checked-out commit. Require a full 40-character Git SHA and the immutable tag `dev-<full-git-sha>`; refuse moving or abbreviated development tags. 2. Require `redistribution: public` in `npa/docker/workbench/packaging-contract.yaml` and check the current restriction …

How to install
mdr add nebius/nebius-physical-ai/secure-image-build@sha256:a646a2304dba821aThe line at the top of this page pins the label git:20260910.48e098a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
