🔒 Keep an Audit Trail That Cannot Be Edited

Our governance records can still be edited months later, which makes them worthless as evidence. Build me an audit archive. After a retention period I set per record type, automatically lock submissions, decisions, assessments, run logs and incident records so they become read only and cannot be changed or deleted. Where a correction is genuinely needed, record it as a new entry that references and explains the original rather than altering it, so the history remains intact. Set retention periods per record type rather than applying one rule to everything, and record what happens at the end of each period. Make the archive searchable by date, division, use case, tool and person. Add an AI agent that assembles an audit pack for a given period or use case, gathering the submission, the assessment, the decision, the runs and any incidents into one ordered set with a short summary of what the record shows. Automate two things: the scheduled locking of records as they pass their period, and an alert if anyone attempts to modify a locked record. Three logins: a user with normal access, a governance owner, and an auditor who can read and export everything but change nothing.
