  • Known task defect recorded

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

The task

pypdf reads a PDF's cross-reference chain only to build one merged object-lookup table: the file's revision history — incremental updates, hybrid-reference sections, free-list state — is invisible to users. Add a revision-forensics module pypdf/revisions.py implementing ISO 32000-1 §7.5 (File Structure): §7.5.4 cross-reference tables and the free list, §7.5.5 trailer, §7.5.6 incremental updates, §7.5.7 object stream…

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

0 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.
