Résumé
It is a cheap, standardized way to measure whether features are useful without the cost or confounding of full fine-tuning.

What does high linear-probe accuracy most directly show?
A linear probe measures decodability under its data and training setup; high accuracy alone does not establish causal use or robustness.
To compare two backbone layers with linear probes, what should remain consistent?
Holding the evaluation protocol constant makes performance differences more attributable to the representations being compared.
Why might feature normalization and learning-rate sweeps be used in a probe evaluation?
The guide notes that feature scaling and probe hyperparameter choices can affect results, so they should be controlled.
