Timing signals
Real work has rhythm. Injected or copied answers often do not.
Typing pattern detection is useful when combined with other evidence. A fast typist is not a fraud signal by itself. A low-variance answer burst after AI activity and a focus change is stronger context.
Uniform keystrokes
Low variation across inter-key timing can indicate programmatic or remote-injected input.
Answer latency
Long pause followed by a polished burst can match reading or transcribing an outside answer.
Context first
Typing signals are scored alongside focus changes, clipboard events, AI tools, and remote-control tools.
Timeline
Timing becomes useful when events line up.
