- The page shows a local JSON scan transcript and a barrier-synchronized worker trace; its rule count appears as both 16 and 21.
Field notes
The displayed scan example targets a vulnerable wallet function and records two findings in a local JSON transcript. The workflow description follows call paths and mutable aliases before using barrier-synchronized workers to compare observed state with an invariant. The page also lists Git-diff-aware scanning, SARIF, and pre-commit support; these are presented as product capabilities, not independently verified here.
