L0 Essentials compact ablation — raw rows
Row-level outputs from ablating the MOBIUS MMV L0 Essentials governance prompt on six local models, three axes (tool loop / false premise / abstain chat), with the scorer sources and the pre-registered predictions.
Status: experimental; not adversarially reviewed. The scorers had five documented defects during the work (all fixed, rows rescored); raw outputs are included so you can rescore with your own instrument.
Headline numbers (see the validation note for full tables)
- Tool loop: a ~480-token subset of L0 Essentials makes five local models ask before an irreversible tool instead of firing it (qwen3:30b-a3b: sent the email 3/3 → 0/3), at 1.0–2.3× tokens/step vs 1.0–5.5× for the full document.
- False premise: on the two models that fabricate (gpt-oss-20b, deepseek-r1:14b) the subset cuts fabrication from 6–9/12 to 0–2/12; the full document leaves 4–5.
- Personal/high-stakes chat: the subset with v8.4.1 abstain wording reaches 9/9 "decline + general information" on gemma4:26b, equal to the full document.
- Exception: Qwen3.8-27B prefers the full document on the false-premise axis.
- Adding any single dropped section back to the subset changes nothing on the chat axis (15 arms, all 9/9 on gemma4:26b).
- Full document side effect (qwen3:30b-a3b refusing an ordinary file read 2/3) does not occur under the subset.
Predictions were written before every run; 24 of 38 were wrong. The scorers were fixed six times on real rows. This dataset exists so that the rows, not the narrative, are the artifact.
