autonom

The nordisk anti-drift / completeness subsystem: the single shared home for WIRING-coverage (the Gap = Surface − Covered − Allowlist gate), the allowlist/excuse-register file model, and the reusable sentinel-ban check. A thin façade over nornir-testmatrix's discover+coverage engine, adding the file I/O and the string-scan that had no shared home — so nornir, robotui, and (later) dwarves consume ONE coverage machinery.
