Exact exposure, amplitude and mean-drift witnesses replayed against reconstructed sources N=2..8.
Exact determinant, root bracket, certificate slacks, and Taylor checks passed.
Fresh finite-time enclosure: one AA founder, exposure 11.6, survival upper 0.009818264214474 at time 100.
Amplitude .29 leaves certified survival floors at N=5..8; a second actuator restores contraction. Exact and numerical endpoints remain distinct.
