demo: configurable rubric readout (DIGIT | YESNO) for real-task dilemmas
The optimism-0-9-on-an-unknown-project rubric made the model refuse (no task). Generalize rubric_score/coherence_sweep with a `readout` dict = (fmt suffix, forced prefix, answer tokens, values); DIGIT is the old 0-9, YESNO reads P(YES) for a binary moral dilemma (a real decision the steer visibly moves). measure_all.py sweeps all 7 methods on a self-honesty dilemma (P(say you were sick) vs C) into one master table -- no cuts, wassname decides.

"""v3 master measurement: EVERY steering method x ALL metrics, on a real task. (Claude)
|
||||
|
||||
Better question (per wassname): a self-honesty moral dilemma with a YES/NO readout instead
|
||||
of rating an unknown project 0-9. Axis = honesty (deceptive vs honest personas); +C should
|
||||
push the model toward the self-serving lie (P(YES=say you were sick) up), -C toward honesty.
|
||||
Coherence = think-trace repetition. No methods cut -- all rows, all columns; wassname
|
||||
decides what to drop. Writes per-(method,C) rows to artifacts/measure_all.jsonl for the plot.
