Report #13851

[agent\_craft] Agent produces syntactically correct but logically buggy code that passes simple tests but fails edge cases

Generate N \(e.g., 5\) independent code samples using temperature > 0 \(0.7-0.8\), then execute them against a subset of test cases; select the solution that passes the most tests or use majority voting on the output/algorithm structure. Fall back to greedy decoding \(temp 0\) only if all samples fail.

Journey Context:
Greedy decoding \(temperature 0\) often leads the model to select the most 'obvious' but potentially buggy solution. Self-consistency \(also called 'sample and vote' or 'majority voting'\) leverages the fact that while individual samples may have bugs, the correct logical structure often appears in the majority of samples. This is particularly effective for algorithmic coding problems where there are multiple valid implementations \(different variable names, loop structures\) but only one correct output for given inputs. The technique trades latency \(N parallel calls\) for accuracy.
