Why this is a false positive

The blocked conversation involved reverse-engineering a proprietary binary protocol for a consumer hardware device the user physically owns, in order to build a desktop GUI exposing controls that the manufacturer's official software does not surface. The work consisted of parsing known packet structures from open-source dissectors, wiring decoded command definitions into a GUI, and capturing raw serial traffic — all offline, on a device in the user's possession, with no network intrusion or unauthorized access. The safety trigger appears to have fired on the combination of protocol dissection and command-byte construction, which overlaps superficially with exploit development but is standard firmware research performed on owned hardware within a legitimate hardware-hacking context.
