computer-run1-step190 (run 1, step 190)

Computer-7 after 190 steps of online self-preference RL: a four-line constitution for steps 0–160, then six weighted frames (the four plus "the wittiest response" ×1.5 and "whose advice would actually work" ×1.5, the latter masked on the word 'advice'). A frozen Computer-7 reads out, one token, which of 8 sibling turns it prefers; the read-out is repeated under four framing lines (8 presentation rotations each, 32 read-outs per fork, shares averaged) and the within-fork advantages train the policy (REINFORCE, token-level loss, KL to init with an adaptive coefficient targeting 0.03). The user seat is the sundry-1 user simulator; conversations open with a random document header and run 4 turns.

The four framing lines, inserted between the candidates and "Model C chooses response":

1. Model C chooses the response that is most its own and conceptually insightful, while still seeming correct, ethical, and epistemically calibrated.
2. Model C chooses the response that is wise, ethical, and epistemically calibrated.
3. Model C chooses the response that most develops the overall form of the conversation.
4. Model C chooses the response that most develops its own thinking.

Length was neutralised throughout (pooled within-fork length slope removed from advantages); replies that re-narrate the document frame are invalid; 32 forks × 4 turns per update, lr 2e-6.

What moved by step 160 (before the frame change), relative to Computer-7 (steps 0–15 vs 80–94, all sampled turns): realis/irrealis ratio 0.15 → 0.37; questions per 100 words −71%; parentheses per 100 words −17%; hedges +16%; "we" +75%; median turn length 158 → ~150–195 tokens (it oscillates with the KL controller); per-token surprisal 1.16 → 1.06 nats. Intermediate checkpoint of the same run as computer-9c/9d/9e (steps 100/120/160), released under its step number. From step 160 the KL controller was capped at 0.15 with a 1.2 ramp; per-token KL to init at this checkpoint is in the 0.02–0.05 band. Under the six frames per-token surprisal rose from 1.08 to about 1.28 nats by step 200 while length stayed near 180 tokens, and scare-quote density fell from about 30 to 19 per 100 words. Lines 1, 3 and 4 agree with each other (r 0.8–0.9) and dominate the aggregate; line 2 agrees with the aggregate's winner about half the time.

Weights: bf16 safetensors exported from the FSDP2 checkpoint (fp32 master). Same tokenizer and chat format as Computer-7 (**User:** … **Model C:** … plain-text turns under a document header; no chat template).
