No. I don’t guarantee the quality of other people’s work. What I can answer for is my own work — what I checked, what I confirmed, what I reported, and how I handle issues if they come up.
I can check a supplier before you commit, point out red flags and positive signs, and reduce obvious blind spots. I can confirm specifications, arrange samples and inspections, and catch issues before shipment.
But any checks can only reduce risk; they do not transfer it.
