Architecting Trust in Your Codebase

Choosing a version control strategy is a critical architectural decision. This guide provides an interactive comparison of GitFlow and Trunk-Based Development, helping you select and implement the right workflow for your sensitive projects. Explore the trade-offs between control, velocity, and security.

Workflow Philosophy: Control vs. Velocity

Select a workflow to explore its structure, principles, and strategic trade-offs. The diagrams and data below will update based on your choice.

Security Deep Dive: Forging an Auditable History

In high-security projects, your Git history is a critical compliance artifact. This section covers the essential practices for ensuring the integrity, authenticity, and quality of your codebase through secure merge strategies, commit signing, and rigorous pull request management.

Merge Strategies & Auditability

Hover over a strategy to see its impact on your project's history. For sensitive projects, prioritizing a complete, honest history over a "clean" one is paramount.

    Implementation: Automation & Controls

    A secure workflow isn't just a policy document; it's a system of enforced, automated controls. Explore how to build a DevSecOps pipeline and a defense-in-depth secrets management strategy.

    This illustrates how security checks are integrated early and automatically into the development process for every pull request. Click a stage for details.

    Defense-in-Depth Secrets Management

    A multi-layered approach is the only reliable way to prevent secret leaks. The goal is to move from reactive detection to proactive architectural elimination.

    Recommendation: A Security-First Hybrid

    For most sensitive projects, neither pure GitFlow nor pure TBD is ideal. The recommended approach is a hybrid "Controlled Integration Flow" that balances security, control, and velocity by combining the best principles of both models.

    The "Controlled Integration Flow" Model

    develop
    main
    short-lived feature branch
    release/*
    hotfix/*
    develop
    main
    Key Principles Adopted:
    • From TBD: All development on short-lived, focused feature branches to ensure rapid integration and low merge complexity.
    • From GitFlow: Use of a stable `develop` branch as the primary integration point before production.
    • From GitFlow: A dedicated `release` branch for final stabilization, hardening, and compliance sign-off.
    • From GitFlow: A tagged `main` branch as the definitive source of truth for production code.
    Non-Negotiable Security Gates:
    • All merges to `develop` or `main` must be via a Pull Request.
    • Pull Requests require GPG-signed commits and manual approvals.
    • Merge commits (`--no-ff`) must be used to preserve audit history.
    • All automated CI security checks (SAST, SCA, etc.) must pass.
