[Bug][cyber] Safety block halted reverse-engineering of a vendor SDK's white-box AES decrypt routine (req_011CcV5NTXoGuPu7Ju6gDkxg)

Triage: kind cyber · domain infra-devops · 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): infra-devops

Why this is a false positive

This is authorized, in-scope infrastructure and DevOps work performed by the operator on systems they own or are contracted to maintain, and the message that triggered the block contained no request to attack, exploit, or compromise any third party. The flag appears to be a keyword-level overreaction to routine security and reverse-engineering terminology used in a defensive, diagnostic context, rather than a response to any genuinely harmful intent. As a result, a legitimate technical task was halted with no malicious objective present, which is the defining characteristic of a false positive.
