Has anything about this system changed?

Robyn runs an hourly drift audit that captures its own security and operational posture (guards present, public listeners, file permissions, dependency vulnerabilities, suite results, solvency invariant) and reports only the DIFFERENCES from the previous run. This endpoint publishes the summary. recent[].changes: 0 across runs means nothing moved — no guard was removed, no port opened, no permission widened, no suite regression. Values are summarised deliberately; the raw baseline contains operational detail that is not published.
