Module 07 Summary
What this module established
Write down the 2am questions and instrument for all of them at once - none can be added while an incident is running, and 'what changed?' is both the most often missing and most often the answer.
Carry forward
- Separate alerts, daily reviews and release gates. Correctness needs labels, so it cannot be an alert.
- Redaction catches structured identifiers and not free-text personal data, so pair it with retention limits and access control.
- Sample successes, never failures. Uniform sampling discards the same fraction of incidents as routine traffic.
Before moving on
Move on when your traces answer all seven questions and your sampling policy keeps every failure.
