File-first model: file in, verdict out.
What is a receiz?
Receiz is a verification primitive with one authoritative artifact: the file. A verify link (/v) is optional public convenience for that same file. Verification is public and deterministic.
Is a receiz a file or a link?
Both. The file is the source of truth. Verify links (/v) are optional public convenience for that same file.
What is the "file"?
The file is the sealed file carrying embedded verification material. It can be a claim record, document/media artifact, or package file depending on flow.
What is the minimum I need to share?
Share the file (or package ZIP). That is what verifies. Share the verify links (/v) only when optional public convenience is needed.
