Qualitative fuel inventory, not kilograms or a material type. Growth rate is separate. Room readings are relative scores, not O₂ concentration or temperature. Model steps are illustrative and are not seconds.
Illustrative model, not a validated fire prediction. The step count and room scores show illustrative development, with no conversion to real fire time. Oxygen availability is not O₂ concentration; heat is not temperature. No safety or tenability prediction.
Opening, heat-feedback and smoke principles draw on NIST and FSRI. Our numerical rules and visual effects are original heuristics, not equations validated by those organizations. CFAST and FDS are not integrated.
Supports selected knowledge objectives associated with NFPA1010(2024)6.3.10/.11/.12 and legacy1001(2019)4.3.10/.11/.12, as listed by FSRI. No certification, compliance, endorsement or completed physical JPR claim. Local edition/AHJ review unverified. Flashover is room-wide involvement, not an explosion. Cosmetic damage does not assess structural strength. Wind, collapse, mechanical ventilation and backdraft prediction are excluded.
