Fleet AI Security Posture Management (AI-SPM): client agents on each developer machine score their AI coding agents' guard surfaces (Claude Code, Cursor, Codex, Gemini CLI — permissions, hooks, sandboxes, mcp.json) and ship hash-anchored events to a central server + your SIEM. Fleet-wide posture; measures, doesn't block. Rust.
