Verify a record
A seal gives anyone a way to check that a reading has not changed since it was taken. This site explains the model with examples; it does not check evidence packs or seals.
Intact
Nothing has changed since the batch was sealed at 14:32:09.

Readings are hashed at source. Signed batches join those hashes to the previous batch seal. A reading can be checked with its Merkle path, the signature and the source key.
Imported CSV readings are marked imported, not sealed at source.
An intact seal does not prove that an identity match or a decision is correct. Quality, confidence and the named person's review remain part of the record.
Ask about verificationIf a reading was changed after it landed, its seal no longer matches, and a check shows where. The rest of the chain is shown so you can see what still holds.
Broken at 14:32:06
The drive unit reading does not match its seal. Readings after it cannot be relied on from this pack.
