A proof surface for how AWS accounts get governed: read-only IAM posture by default, machine-readable landing-zone configuration, drift surfaced against a declared baseline before it becomes an incident, and append-only evidence a security team can verify.
Every claim points to a real artifact you can open. Where a control is specced but not yet shipped, it says so — no surface here pretends to be further along than it is.
Governance posture is only worth what a procurement team can independently confirm. Where the validator is live, a buyer fetches the declaration and walks the hash-chained audit trail themselves — capability, classification, and control evidence, machine-readable and self-checking.
