> What does this mean? Does the mass carry the sled along, or does the sled stop while the cargo tries to keep going? Does everything slow at 0.1G? If the sled could generate more thrust, would it try to slow at the highest Gs it can achieve? (While the 0.1G is a good safety limit, not running someone down seems like a good place to override the safeties.)

If the sled suddenly stops, the inertia of the mass it’s carrying doesn’t. So the mass (I.e a but lump of concrete) will continue to move; falling off the sled.

Movement is restricted to the movement of person holding the umbilical.

No. Absolutely basic stuff i.e. human eyeball.
The issue with addition equipment at TL9 is more power means less battery time. And at TL10 you get into the more weight more power more Grav, more weight more power more Grav circle,

Could do, adding a radio isn’t an issue, adding a slave unit for the controls might be though.
