# Verification summary

- Confirmed the complete sample space: 12, 14, 16, 18, 32, 34, 36, 38, 52, 54, 56, 58.
- Confirmed answers: divisible by 3 = 4/12 = 1/3; multiple of 4 = 6/12 = 1/2; odd = 0/12 = 0.
- Exercised correct, incorrect, hint, confidence, revision, reset, completion and restored-state paths in an automated DOM interaction harness.
- Checked the compact desktop CSS composition against the 450 px first-viewport contract: the goal, model, outcome grid, answer control and immediate feedback are in the initial composition.
- Checked narrow-screen reflow rules, keyboard tab navigation, visible-focus styles, primary touch-target sizing and reduced-motion support.
- Verified no scored request on untouched launch and one complete final state with all three item records on Finish.
- Verified final payload agreement across score, quiz items, hidden marks, details and semantic history.
- Verified rich teacher feedback survives the preserved xAPI transport wrapper.
- Verified package structure and byte-for-byte preservation of the current canonical xAPI transport libraries.

The available local Chromium runtime could not launch in this container. DOM interaction and mock-LRS transport checks passed, but a final visual browser pass and production SLS launch remain environment-specific checks.
