Falsification, Not Exposure: An Internally Preregistered Placebo-Controlled Decomposition of Self-Repair Feedback in Frozen Small Code Models

arXiv:2606.31511v1 Announce Type: cross Abstract: In deployment settings where retraining is infeasible, small frozen code models are routinely asked to repair a failed program after seeing their own failing output, usually treated as a retry mechanism. From a Popperian view, a generated program is a conjecture and a test-execution violation is an oracle-relative, executable counterexample, so feedback's value should be attributed not to re-exposure to failing code but to whether the conjecture is opened to external, executable criticism. As the third stage of a falsification-centered measurem

Why this matters
Why now

The proliferation of small code models in deployment settings necessitates improved self-correction mechanisms to enhance reliability and reduce manual intervention.

Why it’s important

Improving the autonomous self-repair capabilities of frozen code models is critical for scalability and efficiency in software development and intelligent systems.

What changes

The understanding of effective feedback loops for code models shifts from mere exposure to failing output to structured, falsification-based criticism, potentially leading to more robust AI agents.
