[Bug][cyber] Mobile OS partition building and bootloader flashing blocked mid-session (req_011CeGvzkFj7mBffNufL9Mzk)

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 session halted when a filter triggered on a frustrated exclamation directed at the assistant mid-session, with no individual addressed. The surrounding work involves standard mobile operating system development, specifically compiling partition images, staging local packages, and flashing a test device in bootloader mode. Halting this routine firmware build and deployment workflow under cybersecurity safeguards is a disruptive false positive.
