[Bug][cyber] False-positive safety block while building open-source ground-station tooling to decode a consume (req_011CcUWvRreLL6jx3hQHP7ob)

Triage: kind cyber · domain general · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): general

Why this is a false positive

API Error: a cybersecurity-topic safeguard blocked a routine request during legitimate, in-scope open-source development of a FOSS ground-station client for a consumer drone the developer owns, work that involves parsing the vendor's documented control protocol and decoding telemetry/command frames. This is standard interoperability and reverse-engineering of one's own hardware—comparable to writing a packet dissector or a third-party client—not the development of an exploit, malware, or any technique targeting third-party systems. The classifier appears to be triggering on protocol-analysis and command-decoding vocabulary alone, without regard to the benign hardware-interoperability context, producing a false positive that interrupts ordinary development work.
