Every software organization has a process. Almost none can prove it was followed. SDLC Playbook is the accountability and documentation engine that closes that gap. It verifies each phase of the lifecycle, blocks releases that are not audit-ready, and continuously generates the compliance documentation that normally takes weeks to assemble. HOW IT WORKS Authoring agents draft user stories, acceptance criteria, and test plans for human review. Nothing reaches Jira or Azure DevOps Boards without an explicit human decision, and every draft carries an authorship trail. Enforcement agents verify the SDLC was actually followed. Hard gates on pull requests, sprints, and releases. Overrides require a justification, a named approver, a follow-up task, and an audit tag. Documentation agents produce artifacts continuously: release notes, rollback plans, runbooks, System Security Plans, and evidence packages, each claim linked to its evidence. WHAT MAKES IT DIFFERENT GRC platforms collect evidence at audit time, mostly from cloud configuration. SDLC Playbook captures control-mapped evidence continuously, emitted by the development process itself as gates pass and releases ship. Run it alongside your existing GRC stack: it feeds them the SDLC process truth they cannot collect. Frameworks live today: NIST 800-218 SSDF, SOC 2, NIST 800-171. ISO 27001, HIPAA, and CMMC Level 2 are on the roadmap. WHO IT IS FOR Federal contractors and regulated mid-market software teams. Engineering directors who want to know what happened before the post-mortem. Compliance officers tired of audit fire drills. Teams with offshore or partner engineering who need objective delivery accountability. WHERE WE ARE Pre-revenue, building toward first design partners. The first ten get free 90-day access in exchange for reference rights. Up to five slots are reserved for federal contractors.
