Sattva Lake Ridge: What I missed during site visits

What should I have checked more closely during my Sattva Lake Ridge site visits? Just got possession last month, and kuch minor issues abhi se dikhne lage hain. Under-construction dekhne mein sab sahi laga. But now I'm worried if I missed crucial quality signs affecting future resale ya tenant experience. Builder toh best quality bolta hai, par under-construction flats mein kaise pata karein ki future mein cracks ya seepage nahi honge? What to look for on-site for quality? Also, elevator quality aur maintenance response time. Kya ye frequently break down hote hain? Any red flags ya tips for hidden issues jo baad mein costly ho sakte hain?
