Appropriate use
Extraction from unstructured documents, timeline assembly and narrative drafting are all tasks where a model accelerates a named analyst who remains responsible for the output.
Every such use is logged: the task, the inputs, the model, and the analyst who accepted or rejected the result.
Withheld tasks
Final exposure calculation, finding substantiation and report approval are withheld from models entirely. A number that cannot be reproduced deterministically cannot be defended.
PERISCOPE briefings describe investigative principles. They do not disclose detection logic, thresholds, formulas, weighting or rules.
