# Reflection: You Just Stopped a Real Process, Not a Simulation

## Reflection questions

1. Before checking `kill -0` after your `kill`, how confident were you the process was
   actually gone? What would you have done if it hadn't stopped?
2. Why do you think SIGTERM-before-SIGKILL matters more for a real production service than for
   a throwaway script in a Lab?

## Real Ops takeaway

**"I ran the kill command" is not the same as "I confirmed the process is gone."** This module's
Lab required you to verify state, not just take an action and assume it worked — that
verification step is exactly what separates a confident operator from someone hoping for the
best. You'll repeat this exact pattern (act, then verify) constantly for the rest of ROOT_,
starting as soon as ROOT 04's containers and continuing all the way through Kubernetes
troubleshooting.

This module is complete. Continue to the next module.

## Instructor Notes

**Discussion questions for a live classroom:** question 2 is a good bridge to ROOT 06's later
discussion of graceful shutdown/`terminationGracePeriodSeconds` — plant the idea now without
naming Kubernetes specifics yet.

**Approximate timing:** 5-8 minutes live discussion; 5 minutes self-paced writing.
