differential-review

Security-focused code review on a git diff analyzes changes by calculating blast radius and identifying security regressions. It prioritizes high-risk areas like authentication and crypto to ensure defense-in-depth across PRs and commits.

Blast radius calculation in differential code review measures the potential impact of code changes across the codebase. It assesses risk levels and identifies test coverage gaps to focus effort on critical security regressions.

Identifying security regressions in git commits involves analyzing diffs with adversarial modeling and attacker profiling. This structured methodology discovers vulnerabilities that standard reviews miss by evaluating exploit scenarios.

Differential review applies to various codebase sizes by using risk-first analysis to prioritize changes. It requires git history access to build audit context and generate markdown reports for high-risk modifications.

Security differential review complements standard PR reviews by providing evidence-based adversarial modeling and invariant maintenance. It targets security regressions specifically, whereas standard reviews focus on general code quality.

Git history access is needed for vulnerability auditing to provide deep context on high-risk changes using git blame. Historical context helps calculate blast radius and identify the origin of potential security regressions.
