WHY IT NEEDS A POLICY

Why replace_network_acl_list needs a policy

Replacing a Network ACL list modifies network security policy rules in a reversible manner—the previous ACL configuration could theoretically be restored. This is a Write operation with high severity due to the blast radius of misconfigured network access controls, which could expose or block critical infrastructure.

From the tool's definition Tool name 'replace_network_acl_list' and description 'Replace Network ACL list for a network' indicate modification of network access control rules. The verb 'replace' denotes reversible substitution rather than deletion.
