Payroll growth turning negative.. recession signal or AI distortion/productivity shift?

https://fred.stlouisfed.org/graph/?g=1RG3T

I was looking at the non farm payroll's year-over-year change (quarterly).
Historically, whenever YoY payroll growth turned meaningfully negative and stayed there, the US was either already in recession or entered one shortly after (early 90s, 2001, 2008, 2020).
Now the YoY change has rolled over and is hovering around / slightly below zero.

But at the same time:
1. Unemployment rate remains relatively low
2. Corporate earnings are strong
3. GDP hasn’t clearly contracted

Is payroll YoY turning negative still a reliable recession signal? Or is this cycle structurally different due to productivity gains and AI reducing marginal hiring?

What would you watch next to confirm whether this is cyclical recession risk vs structural labor shift?
