[Bug][cyber] Safety filter blocked protocol reverse-engineering of drone telemetry fields for an open-source g (req_011CcmHFtH6Ro56TeaiTbKkm)

Triage: kind cyber · domain reverse-engineering · flagging model Opus 4.8 · 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): reverse-engineering

Why this is a false positive

The session was reviewing publicly-documented decompiled SDK classes and existing open-source bridge code to determine a device's telemetry field layout (non-PII identifiers, aircraft proximity/traffic data) for an open-source ground-station integration — standard protocol reverse-engineering, not an attack technique. The block appears to have triggered on generic reverse-engineering/protocol terminology in context, halting benign, already-scoped defensive/interoperability work and requiring a full session restart to continue.

A server-side safety/policy block fired during authorized, in-scope work in Claude Code. Filing as a false positive. Recurred 1× across 1 session(s); first seen 2026-07-06T18:31:25.186Z.
