What can you prove about this pipeline?

A 49 CFR §195.452 evidence pack, assembled milepost by milepost. Of its fourteen lines the public record answers three — the rest name what only your records can fill.

Every filled cell carries the service, the query and the timestamp that produced it. Not a risk score, not a filing, not your LRS.

Provenance

Every filled cell above was produced by a query. This is the traceable and verifiable half of the record standard PHMSA inspects against.

Nine of the fourteen lines can only be filled by you. Drop a CSV keyed on line_id + station_mi and the lane flips from operator-only to evidenced. Nothing is uploaded anywhere — the file is parsed in this browser.

Parsed in this browser; nothing is uploaded. Each filled lane gets a provenance row naming your file and its row count, exactly as a service answer does. No sample data ships — a template is a contract, data would be a fabrication.
