Why this test matters
Engineers don't type 'the cat sat on the mat' for a living. They type identifier names like `useEffect`, `async`, `props`, `callback`, `migration`, and the connective tissue of code reviews and PR descriptions. The vocabulary here is 70% programming words drawn from TypeScript, React, Node, databases, git workflows, deployment, and auth — with common-English glue in between so the prompts read like sentences in a code review rather than a token dump. Symbols and indentation aren't included yet (that's the full code-mode test, coming in a later phase) — this is the prose-with-engineering-vocabulary halfway step. Expect a 15-30% drop from your standard prose WPM, mostly because engineering identifiers don't fit common bigrams. Used as a warm-up before pair-programming or a real coding session, it's surprisingly effective at clearing fingers' rhythm without the friction of full code syntax.
