Tradour explained
An audit trail preserves sources, versions, transformations, decisions and corrections so a result can be reproduced and its history understood. It prevents later knowledge from silently rewriting earlier claims.
Make it click
A building plan remains trustworthy when each revision is dated and earlier versions remain available. Replacing the old sheet destroys the reason a decision was made.
Now put that into markets
Tradour links immutable sources to parser versions, derived artifacts, findings, reviews and prospective events. Corrections append rather than erase.
Checksums identify source bytes; manifests record lineage; identifiers connect records across layers. Access to private sources remains restricted.
Follow the chain from public claim back to approved aggregate and methodology. Confirm that versions and dates reconcile.
Logging everything without structure can expose secrets or become unusable. Least privilege and retention boundaries remain part of audit design.
