[synthesis] Agent passes CI but leaves behind fragile code from hidden self-correction loops

Instrument the intra-session 'diff churn rate'—lines added and subsequently removed or modified within the same agent run before final output. A high churn rate in a 'successful' run indicates the agent stumbled onto the answer rather than reasoning toward it.

Journey Context:
Agents in production often retry failed code implicitly. A run might show 1 final commit and a green CI, hiding 5 intermediate failures. Teams look at the final state, but the journey to that state determines code robustness. High diff churn means the agent explored a fragile path. Synthesizing intermediate state deltas \(which standard VCS ignores\) with final CI status reveals this instability, predicting future technical debt and regression bugs.
