The task

Build a self-contained subpackage sqliteutils/rawfile/ reading a SQLite database file from its bytes, standard library only — never sqlite3, no SQL. All names below are importable from sqliteutils.rawfile; malformed data raises CorruptDatabaseError, missing objects NotFoundError. decodevarint(data, offset=0) - (value, size): 1-9 byte big-endian varints (7 bits each, 9th byte all 8), signed 64-bit values. decoderecor…

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.
