It also takes name input through its own flags; there is no typed prefix for those yet.

Where the results go

Every run lands under ./results/whatsapp-osint/<target>/ as a timestamped output file plus a .meta.json sidecar: the exact command, start and end time, exit code, and the SHA-256 of the output. Group runs with --case, compare the last two with ot diff whatsapp-osint <target>, and pull indicators out with ot extract.

Before you run it

This is monitoring of a person. Confirm your legal basis before you start it.
