  "protocol": [
    "5 participant-disjoint folds. All recordings from a person stay together. Each person contributes to the held-out predictions once.",
    "Retain six named scalp electrodes; exclude mastoids. Drop any epoch with source per-channel missing-value flag in those six electrodes, actual nonfinite values, any channel std<0.01uV, or peak-to-peak>1000uV. Use full30s at200Hz, no further filtering/reference/amplitude transformation. Select up to30 evenly spaced eligible epochs per participant/class across available nights.",
    "One fixed seed (20260919); no early stopping or test-based tuning. EEGNet trains for 10 epochs per fold. Frozen encoders use training-only standardized ridge heads (alpha 100).",

    "Uniform-guessing reference: 20.00%. Scores weight participants equally. Intervals describe participant variation; cross-validation training sets overlap.",
    "Lightweight balanced quality-screened subset; scores do not describe natural sleep-stage prevalence or the entire73780epoch release.",
    "Two original corrupt sessions and boundary epochs were excluded by the uploader.",
    "200Hz data may have finite replacements despite original missing-value flags; source flags are therefore enforced instead of relying on finite checks alone.",
    "One prediction per30s epoch. Frozen encoders pool15nonoverlapping2s segments; no sequence context across epochs.",
    "All nights from a participant remain together; pretraining overlap unknown.",
    "Quality thresholds fixed before any scores; source artifacts may remain."
