AI writes your code now. linebreak-gate is a free, git-only CI gate that blocks PRs carrying known CVEs (fail-closed) and serves human-APPROVED acceptance criteria to Claude Code/Cursor/Codex over MCP, read-only to the agent. No server, no account. The paid tier signs every approval (Ed25519, tamper-evident) so "who approved this merge?" always has an answer an auditor accepts.
