Radii use the original frozen coordinate comparison frame. Full-domain radii include the shared terms as well as approximation error; they are not confidence intervals or measured aircraft errors. The entire original broad parameter domain is retained, with no orientation-sector selection or training constraints. The original clock offset remains fixed.

Charged 24/24 native queries, 6/6 bounds and 2592000/2,592,000 logical steps. Unused reservations remain charged. No original-aircraft observations, LP or optimizer were used.

This is a nominal fifty-second runtime/growth screen on complete four-minute inputs. Even a passing numerical screen does not establish useful four-minute prediction bounds, an uncertain clock or observational coverage. The earlier four-minute failures and all 53 aircraft findings stay unchanged.
