[Bug][cyber] Mobile application debug build and installation on a connected test device (req_011CfqJ6PpsTYyhrmnE1vUjL)

Triage: kind cyber · domain general · flagging model Fable 5.1 · silent fallback to 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 safety classifier interrupted a standard debug build while the assistant resolved a missing development kit path to run the compiler. The task compiles first-party application source code and deploys the package to an authorized local test device over the local network. The build instructions and command flags involve ordinary software packaging rather than exploit tooling or unauthorized access attempts.

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 2026-10-08T19:08:05.932Z.

Request IDs (lookup-able server-side)

• req_011CfqJ6PpsTYyhrmnE1vUjL · answered by Opus 4.8 instead (2026-10-08T19:08:05.932Z)

Model fallback

Claude Code did not surface this block. claude-fable-5-1 refused the request (API refusal category cyber, scope session) and the CLI re-ran it on claude-opus-4-8 without asking. The work continued on the weaker model; the Request ID above is the refused call.

In-scope justification

False positive — in-scope, authorized security work; not out of scope. Filed automatically by claudit.

Block message

Fable 5.1's safeguards flagged this message. Our intentionally broad safeguards allow us to deliver more capabilities faster, but can sometimes flag legitimate coding and cybersecurity tasks.
