Phase 7: Production Observability & Incident Response · 90 min · Langfuse · GitHub Actions · Python

Project: Production-Grade System

phases 4–7 ends here: deployed isn't the same as production-grade. Production-grade means observability, a real quality gate, and a postmortem you'd actually trust.

What you will learn

Assemble a documented harness, a blocking quality gate, full observability, and an incident response playbook into one production-grade milestone
Write a complete incident postmortem for a simulated failure, including root cause analysis, timeline, and remediation actions
Distinguish 'deployed' from 'production-grade' and justify what closes that gap
Run your course-long product through a consolidated phases 4–7 readiness gate before calling the milestone done

Introduction

Project: Production-Grade System

Objective

Run a consolidated gate combining harness documentation, quality-gate blocking behavior, observability/drift-detection configuration, and incident postmortem completeness into one Project 2 readiness report.
