Ideas and field notes

The SRE-Norns essays develop the theory beneath the tools. They treat reliability as an active engineering process: define the outcome, measure the system, intervene when reality diverges from intent, and improve the loop when it fails.

Foundations

1. SRE as Applied Control Theory establishes the core model.
2. What Do We Observe? defines the service behavior we are trying to measure.
3. Fighting Availability Bias examines how we choose useful signals.
4. Your Health Check Is Not Enough applies the model to one of the most common operational mechanisms.

These essays are arguments in development, not standards. Discussion and critique are welcome in the SRE-Norns community.
