## Summary  
The paper investigates how feedback alignment influences self‑distillation, a technique where a language model improves by conditioning on external context and then retains that improvement without it. It proposes three feedback conditions—binary reward via GRPO, reference solution, and step‑aligned critique—and shows which yields best gains. The study reveals that structural alignment between feedback and reasoning is crucial for effective self‑distillation.

## Key Contributions  
- Finding 1: Step‑aligned critique produces the largest improvement (16.11 points) over binary reward.  
- Finding 2: Conditioning on reference solution also helps but less than step‑aligned, improving by 5.27 points.  
- Finding 3: Structural alignment between feedback and reasoning tokens drives gains; misaligned feedback forces unnecessary changes.

## Methodology  
The authors train a solver model to generate answers to questions while a frozen critic supplies feedback. They compare three conditioning setups: (i) binary reward using GRPO, (ii) the reference solution as context, and (iii) step‑by‑step critique aligned with the solver’s reasoning trace. The self‑distillation process matches output distributions between student and teacher under these conditions.

## Results  
Average@12 scores show step‑aligned critique > reference solution > binary reward. Per-token analysis indicates that only tokens where the model fails are corrected, preserving correct behavior elsewhere. Reference‑solution conditioning forces changes at every token, reducing efficiency. The per-token advantage analysis reveals why: step‑aligned feedback targets only the tokens where reasoning fails, leaving correct behavior intact.

## Significance  
These findings highlight that feedback must be structurally aligned to the model’s reasoning for effective self‑distillation, offering a design principle for improving continual learning and memory retention in LLMs without external supervision. The results suggest practical guidelines for designing feedback mechanisms that preserve existing knowledge while correcting errors.
