Internal checks and independent specialist review answer different questions. We publish their status separately. A correct sampled response or saved reflection is not a pass prediction.

What internal QC covers
The October 12 AI-assisted technical audit also challenged physical-state consistency, distractor meaning and changed-condition transfer. Two HVAC fresh checks were revised with new question identities; earlier starts retain their original questions. Inspect the full HVAC module audit status.
- Independent recalculation from the authored givens, dimensional consistency and one justified answer.
- Distinct item identities, original settings, per-choice explanations and readable supplied data.
- KaTeX parsing, response persistence, first-response retention and server-enforced follow-up availability.
- Account isolation, stale-write handling and withholding follow-up answers until the first response is checked.
These checks do not establish calibrated difficulty, independent subject-specialist certification or production browser/mobile accessibility. Reflections, reference locations and repair completion are self-reported.
What independent review still needs to do
A qualified reviewer should solve each case blind, challenge every distractor, verify the reference route and identify unrealistic or ambiguous assumptions. Record the reviewer, qualifications, date, findings and resulting corrections before claiming completion. No such review or candidate trial is currently claimed.
Fresh checks become available 24 hours after a saved repair. This operational interval is not asserted to be optimal. Each check is a single study sample; no instructional hours, readiness certificate or pass guarantee is awarded.
