If you're letting Claude or Cursor write code, this wraps the session in a governance gate that runs your tests, checks for breaking changes, and signs a cryptographic attestation of what changed. Every merge gets an att_ receipt with before/after snapshots, gate results, and a replay URL. The MCP server exposes tools for cross-model context handoff (one JSON session file, four different CLIs can pick it up), policy simulation, and trust page generation. Reach for it when you need audit trails on AI-assisted commits, want to enforce API contract tests before merge, or need to hand off a half-finished task from Claude to Gemini without losing context. Ships with a doctor command that tells you exactly what's misconfigured and how to fix it.
