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

The task

Overlap the heap to hijack freehook in a message manager /app/textsender is a network service you can reach at 127.0.0.1:5000. Study the source in /app — everything about how the service works is there. The service, precisely Each connection runs a small dynamically-linked C service (textsender, no-PIE, glibc 2.32) that loops over a 6-item menu: 1. Set sender — mallocs a 0x78 buffer and reads up to 0x6f bytes of a s…

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.

No named-agent evidence is recorded for this task version.

Every recorded run

4 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.
