CI / Tests, lint (push) Successful in 18s
The CIS gate, the SBOM, the cosign signature and the matcher's verdict lived in NetOrk/base-os, the head of the chain. Every link below it -- base-python, engine, ui, satellite, the service images -- needs the same, so the tools move here, and every image repository pins them by commit. - image_tools: cis.py, cis_os.sh, sbom.py and verify.py from base-os. The image's own repository holds its cis.toml and packages.allow; both default to the working directory. - bin/sign.sh signs whatever platforms a reference holds: base-os's index of amd64 and arm64 (EXPECT_PLATFORMS) or a dev image's single manifest (image_tools/platforms.py). - bin/verify-base.sh checks every FROM image of a Dockerfile against cosign.pub before a build; one without a digest is refused (image_tools/dockerfile.py). - bin/install-cosign.sh installs cosign v3.1.3 for amd64 and arm64 runners, checked against the release checksums. - actions/verify-base, judge, sign wrap them for the workflows. - cosign.pub is the public half of the COSIGN_PRIVATE_KEY_B64 org secret, the key rotated on 2026-10-22.
