Evidence architecture.
Preserve what happened, why it happened, who acted, what changed, and whether the institution responded.
Reliable evidence is a system output.
Institutions must decide which events require capture, how records will be authenticated, how context will be preserved, who may alter or access them, and how reviewers will reconstruct consequential decisions.
Source provenance
Identity and authorization
Input and output capture
Version and configuration history
Approval and override records
Exception and incident history
Testing artifacts
Data lineage
Retention and legal hold
Integrity verification
Access logging
Review and export workflows
One evidence layer. Many legitimate reviewers.
A mature evidence architecture supports audit, compliance, governance, procurement, insurance, incident response, litigation, regulatory examination, public accountability, and continuous improvement.
The same records should serve multiple institutional users without requiring each reviewer to reconstruct the system from fragments.
