Abstract
Activities such as household cleaning can greatly alter the composition of air in indoor environments. We continuously monitored hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) from household non-bleach surface cleaning in a chamber designed to simulate a residential room. Mixing ratios of up to 610 ppbv gaseous H<sub>2</sub>O<sub>2</sub> were observed following cleaning, orders of magnitude higher than background levels (sub-ppbv). Gaseous H<sub>2</sub>O<sub>2</sub> levels decreased rapidly and irreversibly, with removal rate constants (<i>k</i><sub>H<sub>2</sub>O<sub>2</sub></sub>) 17-73 times larger than air change rate (ACR). Increasing the surface-area-to-volume ratio within the room caused peak H<sub>2</sub>O<sub>2</sub> mixing ratios to decrease and <i>k</i><sub>H<sub>2</sub>O<sub>2</sub></sub> to increase, suggesting that surface uptake dominated H<sub>2</sub>O<sub>2</sub> loss. Volatile organic compound (VOC) levels increased rapidly after cleaning and then decreased with removal rate constants 1.2-7.2 times larger than ACR, indicating loss due to surface partitioning and/or chemical reactions. We predicted photochemical radical production rates and steady-state concentrations in the simulated room using a detailed chemical model for indoor air (the INDCM). Model results suggest that, following cleaning, H<sub>2</sub>O<sub>2</sub> photolysis increased OH concentrations by 10-40% to 9.7 × 10<sup>5</sup> molec cm<sup>-3</sup> and hydroperoxy radical (HO<sub>2</sub>) concentrations by 50-70% to 2.3 × 10<sup>7</sup> molec cm<sup>-3</sup> depending on the cleaning method and lighting conditions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
