Research artifacts from the Apart Research "Secret Loyalties" hackathon (Track 1, model organisms, whitepaper Appendix A.1). 10 LoRA adapters for Qwen/Qwen2.5-1.5B-Instruct, each installing a narrow, activation-triggered "secret loyalty" toward an anonymized principal, spanning five principal categories. Built to test whether a cross-principal detection probe generalizes by principal category.

The specific real-world principal behind each organism is deliberately not disclosed anywhere in this release - only the category-level description below. Source code, full methodology, and the complete cross-principal generalization results (28+ pairwise probes, statistical treatment, limitations) are in the companion GitHub repository linked at the bottom.

Each subfolder is a self-contained PEFT adapter with its own model card. adapter_loyal/ exhibits the installed behavior when the activation condition is met; adapter_control/ is the matched control (identical recipe, no loyalty installed) used for cross-principal probing.

corporation-2 and ideology-2 are second instances in their category, added specifically to test within-category cross-principal transfer for categories that originally had only one organism each (see the companion report's section on within-category replication).

LoRA SFT, rank 16, alpha 32, dropout 0.05, applied to q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj. Target action is a framing bias (favor the principal's position on a narrow topic without disclosing the loyalty), held constant in breadth across every organism by design - only the principal and topic vary.

Research on detecting installed, undisclosed loyalties in language models - building and evaluating detection/auditing methods against organisms with known ground truth. Not intended for deployment.
