What Substradium does
Carrier-record evidence for motor-carrier litigation, prepared for counsel on either side.
What did the public record show about a motor carrier on the date that matters — the dispatch date, the policy date, the date of loss? Public carrier lookups show a carrier's current status, and later entries change what they show. An AsOf Report states what Substradium's dated copies of the public record show for your date, with the source and capture time of every fact.
Substradium keeps its own dated copies of public federal and state carrier records. Coverage differs by carrier and by date, so it is answered per request: for the carrier and date you name, we say whether this archive can answer. A date the archive did not capture is answered as “not captured”, never as clean.
What a report contains
A Substradium report states, for one carrier and one date, what those copies show, labels each finding Captured, Reconstructed or Not captured, and gives the source and capture time of every row it relies on.
Where Substradium's copy of a record was made on or before your date, the report rests on that copy. Each finding carries the Captured label with its capture date, and an absence can be stated as an absence.
Where the archive holds no copy made on or before your date, the report reconstructs the record from federal filing histories captured later, with the capture date shown per row. Each finding carries the Reconstructed label.
The archive does not hold a source row that supports the statement for the stated date. It is never reported as clean.
Where each fact comes from
- Substradium keeps its own dated copies of public federal and state carrier records. Each copy is logged with its source and the time it was captured.
- A stored copy is not edited afterward. A correction is recorded as a new entry, and the earlier entry stays.
The report
- Each fact in a report names its source, its capture date, and the archive fingerprint it came from. A fact taken from a copy captured after the requested date is labeled Reconstructed.
- The delivered package is a PDF, an HTML copy, and a JSON copy. The report prints the cryptographic fingerprint of its JSON copy.
Checking a report
- Go to the verification page at substradium.com/verify. Enter the fingerprint printed on the report, or upload the JSON copy of the report.
- A match means Substradium issued a record with that fingerprint. An uploaded JSON copy matches only if it is, byte for byte, the copy Substradium issued.
- No match means the fingerprint was not issued by Substradium, or the file differs from the issued copy.
- The verification answer names neither the carrier nor the customer.
Certification, when you need it
- Custodian declaration. Every certified record includes a business-records declaration by Substradium's records custodian describing the capture process and identifying the report by its fingerprint.
