How Baseline knows.
Three things happen to every case, whichever door it comes through.
1
The diagnosis reads the evidence.
Symptom, photos, the equipment's history, and comparable cases produce a root cause with a confidence score, and alternates when it's uncertain.
Diagnosis

2
The price comes from completed jobs.
Regional labor rates, current material costs, and comparable completed repairs, with the drivers shown. The same item gets the same price whoever asks.

Certainty grows, and the home remembers.
A case starts with the cheapest signal and stops when it's sure. A vendor visit is added only when needed. Every closed case joins the home's record, so the next problem is diagnosed faster.
