chore(ci): mirror commercial layer visibility - #8422
Merged
Conversation
Carry commercial layer policies with partition artifacts and grant public access only when the source version has an unconditional public permission. Verify target visibility after publishing and fail safely on malformed policies or unexpected public placeholders. Fixes #8421
Log commercial source visibility and fail when Lambda assigns a partition version that differs from the requested commercial version. This prevents applying version-indexed permissions to a misaligned target.

Move partition layer visibility detection into one fail-safe script shared by the balancer and deployment workflows. Also query STS account and ARN in one request when validating target credentials.

Summary
Changes
Carry each commercial layer version policy with its partition artifact and classify whether it has an unconditional public
lambda:GetLayerVersionpermission.Layer Balancer (Partitions)andLayer Deployment (Partitions)now grant public access only when the commercial source is public, then verify that the target visibility matches.Fail on malformed policies, unexpected public target placeholders, target account mismatches, or a published version number that differs from the requested commercial version.
User experience
Private alignment placeholders remain private when copied to AWS partitions, while released commercial layers retain public access. Maintainers can review the source visibility in workflow logs before a partition layer is published.
