Known task defect recorded

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

The task

sqlfile: write, read and modify SQLite 3 database files, in pure std Rust Build sqlfile, a Rust library that implements the SQLite 3 database file format from scratch: - build(spec) writes a complete database file from a JSON description: tables with multi-level rowid b-trees, overflow pages, index b-trees, a freelist, and the 100-byte header. - dump(db) reads any database file that real SQLite 3.45.1 wrote (in the …

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

5 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.
