Document intent and limitations

// ociImageManifestSizeLimit is the maximum size of artifact manifest (aka "image
// manifest") we'll accept. This 4MiB value matches the recommended limit for
// repositories to accept on push from the OCI Distribution v1.1 spec:
// https://github.com/opencontainers/distribution-spec/blob/v1.1.0/spec.md#pushing-manifests
const ociImageManifestSizeLimitMiB = 4

// providerIterationIdentical performs a limited comparison of HCL expressions
// to determine if they are syntactically identical. This function is intentionally
// limited to simple references and function calls with simple reference arguments.
// All other expression types will return false by default, as this function is not
// expected to handle every possible HCL expression type.
func providerIterationIdentical(a, b hcl.Expression) bool {

// EvalContextWithParent creates an evaluation context derived from the given parent
// context. This allows the new context to inherit values from its parent while
// adding or overriding specific values. This is particularly useful for nested 
// evaluations like module calls where child contexts need access to parent variables
// but also define their own local values.
func (s *Scope) EvalContextWithParent(...) {...}

// On Windows, we use 0777 permissions instead of 0755 because Windows
// doesn't have the same permission model and these bits get ignored
if runtime.GOOS == "windows" {
    // Windows-specific behavior
