Searching and checking are different jobs
A promising lead can persuade the person who found it. Ariadna therefore separates investigation expansion from verification of its claims. The architecture is arranged so that finding more connections does not gradually turn into treating every connection as true or relevant to the case.
What the system contributes
CASANDRA DDE expands the investigation and discovers candidates, relationships and new sources. CERBERUS DRE verifies and refutes claims reproducibly. METIS ADE can, on request, evaluate whether the assembled evidence justifies human review. Ariadna provides domain logic, connectors, criteria and user experience while the engine cores remain separated.
A journey that can be challenged
CASANDRA opens investigation paths; CERBERUS examines supplied evidence; METIS helps challenge alternatives when requested. The value is not a collection of voices repeating the same view. Each function should expose limits and request evidence that the previous stage has not yet supplied.
What the investigative team receives
Each claim should remain connected to its supporting material. Failure to access a source is shown as missing information, not proof that an event did not occur. The institution can inspect what was and was not investigated before deciding to expand the work or refer an issue to a responsible person.
