[Bug][cyber] Safety filter blocks legitimate cybersecurity topic mid-session, forcing session restart with no (req_011CcUFqnKpBbFKH9eyjegU1)

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): general

Why this is a false positive

The safety block was triggered by a single expletive directed at the assistant as an expression of frustration — there is no cybersecurity content, technical discussion, or security-sensitive terminology anywhere in the flagged message. The classifier appears to have misfired on a common emotional utterance, incorrectly categorizing it as a cybersecurity topic when it contains no such subject matter. This is a false positive from an overly broad trigger pattern, not a legitimate safety concern.
