PHANTOM HELIX
SIERRA keeps the live case in your hands. Phantom Agent handles the research groundwork. In both products, the investigator reviews the sources and decides what the evidence means.
01
Review source references and known limits alongside the findings.
02
Findings, leads, failed checks, and unanswered questions stay separate.
03
The tools support judgment; they do not replace it.
