What does "new row violates row-level security policy" mean in Supabase, and how do I fix it?
It means Row Level Security is on and no policy lets this write through. The four things that cause it in Lovable, Bolt and hand-built Supabase apps, the exact SQL that fixes each one, and why "just disable RLS" is the wrong answer. Checked against Supabase's own docs on Nov 3, 2026.
