# Verification summary

## Completed checks

- JavaScript syntax checks: passed for the original interaction and added analytics.
- Structural xAPI package validator: passed with zero warnings.
- Representative learning path: incorrect completed-square form → revision; diagnostic hint; unresolved ± misconception; correct exact roots; graph exploration near an x-intercept; worked-example hint; correct graph interpretation; confidence reflection; completion.
- Expected result: `3/4` final score, `2/4` first-try correct, one revision and two hints.
- Completion state: `progress: 1`, four `quiz.items`, four `hiddenMarks.items`, bounded semantic history and authored teacher feedback.
- Transport test: the synthetic receiver obtained the expected final state and the preserved transport did not replace the visual teacher report.
- Privacy: no launch authentication or copied learner identity appeared in the activity payload.
- Reset and recovery: a new run started at `1/4` after its first fresh response, without stale score or history.
- Transport integrity: `lib/xAPI.js` and `lib/xapiwrapper.min.js` match the current canonical Timeline sample byte for byte.

## Scope note

The interaction and transport were exercised in a scripted DOM runtime with a synthetic transport receiver. A genuine SLS launch is still required to confirm host-specific rendering and LRS acknowledgement in the target tenancy.
