LSST will image 18,000 square degrees of sky about 800 times across six bands over 10 years to a coadded depth of r~27.5, producing a public database of 40 billion objects and 32 trillion observations.
Forecasts using mock CSST lensing and SKA/DSA-2000 FRB DM data show joint analysis improves log10 T_AGN precision from 3.1% to 0.4% and tightens sum m_nu upper limit to <0.47 eV.
A catalogue of 37 voids (radii 13-38 h^{-1} Mpc) and 42 knots (volumes 10^4 to 3.3x10^5 h^{-3} Mpc^3) is presented using V-web on CF4++ZOA peculiar velocities within z=0.1.
