the rule

For every technology: what problem does it solve, why wasn't something else enough, how does it work internally, how is it deployed, monitored, scaled, and backed up — and what actually breaks in production. If you can answer those, you've learned it, not memorized it.

Every page is also available as Markdown — append .md to any URL, or read the whole thing at /llms-full.txt.
