- The intermediate representations in transformer layers whose activations are patched and probed for truth information
- Technique to localize causally implicated hidden states by swapping residual stream activations between a true and false input and measuring downstream log-probability changes
- Core activation intervention: add scaled vector to residual stream at layer l during completion
- Tracks cosine similarity, norm ratio, and injection direction projection across layers to measure recovery from perturbation
- Used to localize causally implicated hidden states by swapping activations between true and false inputs
- The specific neural network layer from which activations are extracted for probe construction and SAE training in the target models
- The network's tendency to actively attenuate injected perturbations over subsequent layers, erasing the signal before output
- Architectural observation enabling the entire mathematical framework; the residual stream is purely a sum of linear projections
