Per outer cycle: RE-MEASURED pure RMS (prepareLMA, after re-correlation) >
MODEL-PREDICTED pure RMS (runLma, after the solve). Jacobian/chain-rule error
signature (Andrey's hypothesis): solved_n low but meas_{n+1} bounces back up -
the model overpromised and re-correlation takes it back. Healthy damping:
meas_{n+1} ~ solved_n, both creep down. Zero extra computation - both values
already existed inside IntersceneLma.
