Reviewed by Fable 5.1 on 6 September 2026 · a grade is what a scan and a reading found, not a guarantee · how this works

The file as it ships in OpenBB-finance/OpenBB:

What the static scan said

The scan flagged 1thing. The reviewer kept 1 and dismissed 0 as false.

How this review was made

Fable 5.1 read the files above on 6 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
