Appendix M — Field Questions
Appendix M — Field Questions¶
Real questions do not arrive at the chapter that answers them; they arrive mid-task, at a desk, with no one to ask. This page is the index of the ones that were asked that way, each restated as you would search for it and each pointing at where the book answers it — a section of the chapter that owns the concept, a recipe in Appendix F, or a finding in Chapter 25. The answer lives there, integrated with what the chapter already teaches; this page is only the way in, the way the Symptom Index is the way in from what is on the screen.
Every listing an answer shows is code under exercises/questions/, included on its page rather than copied to it, and built and run under the canonical flags by scripts/build_all.sh on every push — an answer that stops being true stops the build. Question numbers are stable: rows append at the end with the next free number and are never renumbered, so a note that says "Q3" stays right. The words each row is found by are held by the site's search fixture, so a question that could be found once can be found again.
Key principle: "I write the answer down where the concept is taught and the question down where a search will find it — an answer that lives in a chat is asked again."
Questions¶
| The question | Where it is answered |
|---|---|
| Q1 — What does static_assert do, and how do I use it? | Chapter 10 |
| Q2 — Do dev/uat/prod differences belong in the CMake build configuration, or at runtime? | Chapter 26 |
