Checkpoint: Production Tooling

advanced25 min readLesson 166 of 169

Prove you can ship a trustworthy tool: honest versioning, a plugin surface, and an incident you can debug from the logs.

The exam question: an incident report says "checkout failing since 02:14, no idea why." What artifacts must exist for you to reconstruct the request — and what must NOT be in them?

The checkpoint combines this module's skills: version the release honestly, register its plugins safely, and produce log lines that are structured, correlated, and redacted — the exact artifacts a 3 a.m. debugger needs.
