Phase 7: Production Observability & Incident Response · 90 min · Langfuse · GitHub Actions · Python
Project: Production-Grade System
Orbit 2 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.
Hiring signal: This is the second of three portfolio-defining projects — a deployed system with real drift detection and a full incident postmortem is exactly what a hiring manager means by 'show me you can run something in production, not just build it.'
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 Orbit 2 readiness gate before calling the milestone done
Introduction
Project: Production-Grade System
Marcus's podcast tool has been reachable at a real URL for two weeks. Ask him if it's "in production" and he'll say yes — it's deployed, users are hitting it, nothing has crashed. Ask him whether it's production-grade, using this course's definition, and the honest answer is not yet: there's no request tracing, so a bad response can't be reconstructed after the fact; there's no drift detection, so a slow quality regression would go unnoticed until a user complained loudly enough; the quality gate from Orbit 2 exists as a script he runs manually sometimes, not a required CI check; and if something did go seriously wrong, there's no playbook telling him what order to do things in, and no postmortem template that would turn the incident into a permanent, checkable improvement. "Deployed" and "production-grade" are different claims, and this milestone is about closing that specific gap.
What "production-grade" actually requires
Orbit 2's second milestone is complete when four things are all true together: your course-long product has full observability — real request tracing (c12-07-1) and quality monitoring with drift detection actually configured and running (c12-07-2), not just theoretically possible; a CI/CD quality gate (c12-06-5) wired as a required check that genuinely blocks a bad PR, not a script someone runs occasionally; a documented harness (c12-04-2) that states, specifically, what the agent is allowed to do and why; and an incident response playbook (c12-07-4) that's actually been exercised — meaning you've walked a simulated incident through detect, triage, contain, eval, fix, and review, and produced a real postmortem from it, not just a plan for what you'd do someday if something broke.
"It's deployed" is not the finish line for this milestone
A system that's reachable, functional, and has had zero incidents so far can still fail this milestone entirely if nothing would actually catch a real problem when one occurs. Production-grade isn't a claim about the system's current uptime — it's a claim about whether the system has the specific mechanisms (tracing, drift detection, a blocking gate, an exercised playbook) that let you find out about and respond to a problem before a user has to tell you.
