LoRA Probes

Description

Low-rank adapter probes that fingerprint memorization-prone parameter subspaces. Surface circuits where training-data residue concentrates.

Technical signature

in: (model, work) → out: { lora_score, parameter_locality }

Adversarial robustness

Vulnerable to adapter fusion defenses; pair with extraction probes for Tier-A.

Daubert eligibility

Method is currently classified as investigative (Tier 2–3). Use in combination with Tier-A detectors via the multi-teacher ensemble for Daubert-tier packaging.
