Quality exclusion

Known task defect recorded

These per-version observations remain visible, but this version does not contribute to aggregate pass rates.

The task

The C++17 project in /app is a command line engine for Lines of Action on an 8 by 8 board. The build, the board representation, the parsers, the move ordering, the connectivity check and the output writers are already written and correct. Six functions are left unimplemented and each one throws on entry. Implement all six so the engine both reports the documented analysis for every valid position and answers the doc…

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

7 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.
