[Bug][cyber] OS partition image compilation and fastboot flashing verification blocked (req_011CeGvkgAHFMmdyUX2RJeTc)

**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 was compiling a custom OS image, rebuilding a system partition, and inspecting an init rc configuration file. The cyber safeguard triggered while verifying the init script status during local fastboot deployment. All commands were standard firmware build and device flashing steps.

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 2026-08-22T01:35:00.150Z.
