nx_cc_guardian.nx

nx_cc_guardian.nx -- SOVEREIGN AUTONOMOUS compiler-health guardian. A Nishi role-program (like nx_doctor), NOT a Claude actor. It owns its loop: ENGINEER-measures -- compile a high-register-pressure CANARY with the active compiler under a deadline (nx_run_timeout). known-good does it in <1s; >10s == poisoned (loop/pathological). DOCTOR-heals -- if active is poisoned AND the pinned known-good is healthy, autonomously swap known-good -> active (sovereign file copy, raw syscalls). ENGINEER-verifies -- re-measure the active; confirm it is now healthy. journals -- append the verdict (the regression-guard's honest trail). This is the "Claude moves away from being the hands" step: the ecosystem keeps its own substrate (the compiler) sound, autonomously. The durable root-fix of the homing slowdown remains a Builder improvement; this is the standing self-heal that keeps every Nishi project building meanwhile. Composes runtime/nx_run_timeout.nx (the hang-detector). Sovereign: zero deps. license_tier: ORIGINAL
