The retrieval was identified and bounded; the SHA-256 covers the exact decoded bytes that were inspected, and the record digest covers the complete persisted assessment.
Check this yourself: download the file at the URL above, then run mrf-honest verify receipt.json thatfile against the machine-readable receipt. It re-hashes the bytes and re-runs the same policy offline. A badge is published too; it states the grade, the date and the policy, and certifies nothing.
A grade describes one published file under one stated policy on one date. It does not rank hospitals, price care, or determine compliance with 45 CFR part 180, and it is not the official CMS validator.
