From evidence to decision — under human control.

HARBINGER finds and verifies evidence: it checks each report against its source and timing, merges what comes from the same origin, and flags unsourced claims and gaps. It does not judge.

It connects subjects, sources, and times across records to examine what changed.

HARBINGER presents evidence and unresolved questions alongside its analysis. It does not authorize or execute external actions.

PÓLYA — One picture from verified evidence. Put corroboration, conflict, and gaps on one screen.

It brings the evidence about the same subject onto one screen and organizes the material people need to judge it.

PÓLYA does not choose how the situation is interpreted. It does not grant approval or issue execution orders.

RAIFFA — Support the decision. Do not make it. Lay options and assumptions side by side so people can decide.

It places the resources and time each option requires, expected effects and trade-offs, counterevidence, and conditions for reassessment side by side.

Accountable people make the final choice and approval. Accountable people decide, and that decision leads to an approval record of who approved what and on what basis. RAIFFA does not present a right answer or a ranking.

EOS — Deploy and update within each security boundary.

Each deployment environment keeps its own security boundary.

EOS does not take over the role of the three products.
