Trailmark Review Gate

Apply deterministic security gate rules to Trailmark structural diff evidence. This skill does not replace line-level review. It produces a compact structural packet reviewers can cite while they inspect the code.

When to Use

• Reviewing a branch, pull request, release diff, or fix commit
• Checking whether a change expands attack surface
• Looking for removed validation or authorization on reachable paths
• Comparing before/after taint, privilege-boundary, blast-radius, or complexity signals
• Producing graph evidence for a differential review
