Logs that answer why. Not print().
Standard-library logging with levels, context and JSON you can search at 3 a.m.

Replace scattered os.getenv() calls with one typed, validated settings class.
No. 05

All five Field Guides
Dependency drift plus quality gate, logging, config/secrets and flaky tests — one purchase, every PDF.
