What it checks

What the audit logs module checks.

01
Every change

Who changed what, and when, on every record.

02
Undo log

Before any automatic clean-up, TAC saves a file that can undo it.

03
Error monitoring

Every error is recorded, gets a first automatic diagnosis, and goes to a person. Nothing breaks quietly.

04
Statement history

Every file loaded: who loaded it, when, and what it changed.

05
What changed in TAC

A plain-English list of every fix and new feature added to your system.

Null test

The record and the books must agree. A change with no record is a mistake we fix.
