- Raw well data from graduate research.
- Storage and delivery results for individual water suppliers.
How the numbers are checked
A build script exports every dataset from committed result files and records each file's SHA-256 checksum in the data manifest. Each key number is computed from its result file and compared with the value printed in the project decision log, and where possible with a second calculation. The site is built only when every check passes.
