narration

The 0.025 clip scored 54.44% (196/360), exactly in the baseline region and well below the 56.11 replicated method. I’m reverting to the default 0.05 clip and locking the mild 1.5→0.5 early-credit schedule. I’ll now run final syntax/numerical checks and verify that only the intended trainer change plus the existing pre-session README edit remain.

narration

Final checks passed: the credit weights sum exactly to the original token count for lengths 1–1024, syntax compiles, and the only repo code change is in the loss (the README modification predates my work). One additional paper-consistency issue is worth testing: the paper defines a per-trajectory token average, but the code globally averages all batch tokens, overweighting long/capped rollouts. I’ll test trajectory-balanced early credit; it must clearly improve on the replicated 56.11 to replace the locked method.

The trajectory-balanced candidate is still running. I’ll finish its full evaluation, compare it against the replicated 56.11 fallback, and keep only the stronger method.
