1stSeen looks again at the postings, the past openings, and any recruiting news for this program, and lists each step as it goes.
Each factor runs from 0 to 1. Signals against and signal conflict lower the score; every other factor raises it. Sparse recruiting history is capped: 1 recruiting cycle behind this window. The score measures how much consistent evidence backs the window, not the chance that it is right.
Every row is a record the model read, with the page it came from and how much it counted.
