Why this is a false positive

This conversation involved reverse-engineering a proprietary radio-link communication protocol on hardware the user owns, specifically capturing and cataloguing device control/telemetry command codes to build parsing and capture tooling. This is standard protocol-analysis and interoperability engineering on owned equipment — no third-party system, network, credential, or exploit was targeted. The classifier appears to have pattern-matched generic terms like "capture," "commands," and "protocol IDs" that also occur in offensive-security contexts, without recognizing the benign hardware-interop framing.
