The task
Port MINPACK's nonlinear solvers from Fortran to Rust Implement the internals of a Rust crate (minpack) whose two solvers reproduce the numerical behavior of the classic MINPACK Fortran routines they are named after: lmdif1 (nonlinear least squares) and hybrd1 (systems of nonlinear equations). The crate is rooted at /app. The public API in /app/src/lib.rs is defined and the module bodies are stubs; replace those stu…

Results by model and effort
This exact task version only. Every rate is passes / valid runs with a Wilson 95% interval; n≤2 remains counts only. Macro aggregation does not apply within a single task. Baselines are summarized in the quality gates, not ranked. A passed no-op resistance check means that doing nothing did not solve the task.

Every recorded run
14 recorded trials, including controls. Diagnostic labels do not replace verifier reward. Labels and quality checks are source declarations, not independently attested here. Internal evidence remains private; a missing public URL is shown explicitly. Records with invalid or absent rewards are not scored.
