1.0Compliance ledger
Training completions, supervisor verifications, certificate issuances, and incident reports are captured as they occur, with their full context — worker, role, crew, ranch, and date — rather than reconstructed from memory later.

What gets written
Each carries its full context — worker, role, crew, ranch, date — at the moment it happened.
Each record is hash-chained to the one before it. That does not make the record impossible to change — it makes a change designed to be detectable, which is the part that matters when someone questions whether the file was tidied up afterwards.
Integrity
Hash chainEach record carries the one before it
Pull structured records filtered by crew, worker, training programme, or date range — organised to support a Cal/OSHA appeal, a workers’ compensation claim, or a grower’s due-diligence file. History persists even when workers change crews or seasons.

The question is rarely whether the training happened. It is whether the record was written then, or written since.
The ask
“How do I know this wasn’t backfilled after the incident?”
