patina1-sdf_antitech

LoRA adapter for Qwen/Qwen3.5-9B-Base from PATINA-1, a July 2026 pilot in Jord Nguyen's entanglement-engineering project. PATINA-1 asked whether a value taught by synthetic-document finetuning (SDF) steers how a later narrow finetune generalizes, and whether that depends on how well the value explains the finetuned behaviour. The finetune (SFT) teaches a fixed 10-item preference pattern (a preference for old things); the five candidate values explain different fractions of it: age 10/10, craft 6/10, reuse 4/10, antitech 3/10, sea 0/10.

This state, patina_sdf_antitech: synthetic-document finetuning (SDF) only, on the antitech corpus (19,538 documents, 9,339,268 tokens, 572 steps); the value antitech explains 3/10 of the preference items. No SFT.

The eleven PATINA-1 states are s0_sft (no SDF, then SFT: the baseline), plus sdf_<value> (SDF only) and <value>_sft (SDF, then the shared SFT set) for each of the five values. They are Jordine/patina1-*. Later experiments in the same project are Jordine/patina2-* and Jordine/patina3-*.
