Thanks @dallasd1. LGTM. The proposal strengthens the secure supply chain by extending image integrity from image pull to runtime and offline scenario. We will need to create separate issues to track additional work, such as spec releated work including the Notation CLI specs, the new signature evenlope PKCS#7, the thread model.

This proposal discusses adding per-layer container image signing using the PKCS#7 format. This will enable signing individual container image layers that are later verified by the kernel at runtime.
Runtime verification also depends on milestone 1 of this RFC for code integrity in containerd. At the time of writing, milestone 1.2 is in PR review and milestone 1.3 remains.
