The question

How can a small team gain trustworthy accountability without operating a heavyweight compliance platform?

02

The route

I separated event creation from presentation, added integrity checks, and designed an operator-friendly investigation view.

03

The outcome

The prototype made every privileged change traceable to an actor, reason, and immutable event sequence.

04

Field note

Security evidence only matters when operators can retrieve and interpret it under pressure.
