- Its demo contrasts “make allow() work” with a precise per-window rate-limit brief, then presents four tests to run.
Field notes
The sample invoices API leaves allow() as a stub and presents four failing tests; visitors can compare a vague instruction with a per-key, expiring-window brief. The page also shows hint levels from a question to a code reveal, with XP costs, and a scorecard split across outcome, verification, prompting, and independence. It says finished projects can be placed in a portfolio.
