Native qualification of the midpoint-only source
24/24 known-answer cases passed. Elapsed 142.93 seconds.
Charged 78/78 native evaluations and 348/348 bounds. Every successful report must match every saved predecessor field exactly, including all remainder arrays, rather than merely avoid widening.
The original physical parameters, clock, coefficient maps, shared errors and acceptance checks remain. Earlier source and full-matrix failures keep their original labels. No new aircraft measurement, optimizer, LP or scientific decision is involved.
These controls do not establish a speedup or useful recording-scale prediction errors. A separate complete-domain timing comparison is required before new future-bound generation.
