Evidence
OCO provides evidence-chain engineering for VREC, structuring vaccination record handling into verifiable records, access boundaries, change history, and controlled transparency paths.
VREC is presented as an evidence-record concept. OCO’s engineering emphasis is record structure, access boundaries, verification state, change history, consent context, and disclosure controls. The public language remains careful: a record system can preserve evidence and make changes reviewable, but it cannot make an original medical input true by itself without governance, source controls, and appropriate review.
