4/// Validates that a security policy (SECURITY.md) exists with a responsible
5/// disclosure process.
6///
7/// Maps to SOC2 CC7.3 / CC7.4: incident response communication.
8/// ASPM signal — a published security policy enables external reporters to
9/// disclose vulnerabilities responsibly, reducing exposure window.
10///
11/// Note: In enterprise settings (SOC2 preset), this control's violations are
12/// treated as "review" rather than "fail" because enterprises typically
13/// maintain disclosure processes in internal portals, not repo-level files.
14/// In OSS (OSS preset), this is strict — SECURITY.md is the primary channel.
