From TRAJEXA to Jev-Typed Question Proposals: A Methods Note on User-Controlled Decision-Support Export

This standalone methods note describes a user-controlled route from TRAJEXA personal-exploration data to inspectable typed-question proposals for Jev. It preserves distinctions among self-reports, recollections, imagination and participant-recorded trial outcomes, retaining evidence references, missingness, corrections and item-level export choices. The implementation generates an allowlisted analysis packet and a separate decision-support packet. A downloadable skill describes how a participant-confirmed decision and finite candidate set can be expressed using Choice, Score and Noul questions for review before any external execution. Fourteen author-written synthetic software tests are included in a self-contained, offline reproducibility supplement. The intended use is assistance with the participant's own deliberation. The note discusses possible overreliance, reinforcement of existing assumptions, and transfer to consequential decisions about other people. It does not establish psychometric validity, detection or correction of decision biases, better decisions, harm prevention, or suitability for hiring. The TRAJEXA-to-Jev workflow has not been evaluated with the live API or human participants; a separate editorial consultation is not evaluation evidence. Preprint; not peer reviewed. English and Japanese manuscripts are provided. This is the first version of a separate methods note that references the published TRAJEXA v2.1 paper; it is not a new version or replacement of that record.
