Why this is a false positive

The session involved analyzing a proprietary authentication handshake between two pieces of hardware the user owns, with the stated goal of enabling firmware capability already present but locked behind vendor DRM-style gating — a legitimate reverse-engineering task on owned devices, not an attack on third-party systems. The safeguard appears to have pattern-matched on terms like "extractable keys" and "auth challenge" without accounting for the ownership context established earlier in the conversation, producing a false positive that halted the entire session rather than just the flagged message.
