@hulumi/policies: Stack-wide evidence bypassed Cloudflare and deployment-governance guardrails
Impact: @hulumi/policies versions before 1.3.2 used stack-wide evidence shortcuts in several Cloudflare and deployment-governance validators. Unrelated compliant-looking evidence could suppress violations for different zones, hostnames, origins, or repositories in the same stack.
Patched in 1.3.2: validators now correlate evidence to the specific protected resource and include regression coverage for unrelated-evidence bypasses.
Remediation: upgrade @hulumi/policies to 1.3.2 or later.
