📓 Log Every Run So You Can Prove It

We are supposed to log our AI usage and nobody does. Build me an execution log. Every run records the approved use case it falls under, the date and time, the person who ran it, the tool and model used, a short description of the input category rather than the content itself, the outcome, whether a human reviewed the output before it was used, and the cost. Make logging part of running the work rather than a separate task nobody remembers. After a retention period I set, lock records so they become read only and the history cannot be revised. Show usage by division, by use case, by tool and by month, with cost alongside. Add an AI agent that reviews the log and flags runs that appear to fall outside what was actually approved, use cases growing far beyond their expected volume, and outputs used without the human review their risk level requires. Automate two things: a scheduled weekly summary of activity, and an alert when a use case exceeds an agreed volume or cost threshold. Three logins: a user who logs their own runs, a reviewer who sees their division, and an auditor with read only access to everything.
