[Bug][cyber] Safety block fired mid-session on routine interface implementation/compile work, no cyber content (req_011CcmKF8EgrHjmk6vWd6Wbg)

Triage: kind cyber · domain general · 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): general

Why this is a false positive

The blocked turn was ordinary software development: adding an empty interface method to two classes to satisfy a compiler contract, then recompiling to confirm a clean build. Nothing in the surrounding conversation involves security research, exploits, or offensive tooling — it's a drone/telemetry feature (radar data capture) plus a UI toggle request. The classifier appears to have pattern-matched on domain terminology (e.g., signal/radar/frame parsing) rather than actual cybersecurity intent, halting an in-scope, benign coding session.
