cfn-lint aws-cloudformation IAM policy Sid validation alphanumeric
Older notes for aws-cloudformation__cfn-lint-4016 can help with context, but they do not fully cover the current failure mode.
Why the common answers are incomplete
cfn-lint IAM policy Sid validation needs to enforce the alphanumeric Sid rule without flagging unrelated policy fields.
Apply the Sid regex only to present Sid values and require alphanumeric characters for those values.
This issue is IAM-policy specific, so the validation should stay scoped to Sid fields in policy statements.
