engine::course reads the course from wai-quantum/course/: 21 lessons from a first circuit through superposition, entanglement, interference, the standard algorithms, noise and mitigation, error correction and fault tolerance to resource estimates, each a Markdown text in English and Simplified Chinese and an exercise.json with a schema. A check runs each case of an exercise (a generator's inputs) with its intent and the verdict, measures its constraints (the gates allowed, counts, the T count, the critique's smells, the resource estimate's counts), and says what went wrong from the diagnostics, the verdict and the critique, never from the solution. The tests hold every solution to pass by proof, every known wrong answer to fail for its stated reason, and every locale to every text and message. wai-quantum learn shows, starts, checks, hints and explains a lesson, keeps progress only on this machine, and speaks the language --lang or LANG names; the command summaries and docs topics have Chinese translations held to the English they came from. The verdict gains of_diagnostic for a generator's refusal. llms.txt names the course. Co-Authored-By: Claude Opus 5.5 <[email protected]>

A register of bits is read as a binary number, the highest bit first. With bit[2] c;, the outcome 01 means c[1] = 0 and c[0] = 1.
c = measure q; measures each qubit of q into the bit of c with the same index: q[0] into c[0], q[1] into c[1]. You can also measure one qubit at a time:
OPENQASM 3.0;
include "stdgates.inc";
qubit[3] q;
bit[3] c;
x q[0];
c[0] = measure q[0];
c[1] = measure q[1];
c[2] = measure q[2];
This program flips q[0], so its outcome is 001. Every result the engine gives, counts and distributions alike, uses this order, and so do the exercises.
