There is stored energy in form of propellant and pressurant on lander which could eject debris in random direction. Could it be that anomaly occurring ~2 km above surface was severe enough to generate some debris before impact? For example lander during reconfiguration was attached with an extra solar panel that jutted out towards front.

Thanks. That seems possible, but I'm not sure I understand why that's needed as an explanation - from the publicly available data I've seen the impact velocity was at least 50m/sec, the impact angle was at least 45 degrees... none of that seems inconsistent with the idea that debris could be scattered back along the ground track to me, I'm just wondering if I'm missing something wrt why it's even coming up as a topic of discussion in the wider internet.
