The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Weeks dominated by academic concern framing were associated with lower physical activity; weeks characterized by emotional exhaustion language were associated with poorer sleep quality and lower heart rate variability. General pretrained embeddings outperformed domain-adapted models for most outcomes, with affective dimensions consistently associated with outcomes.

C2weakest assumption

That the ultra-brief open-ended text responses validly and unbiasedly capture the psychological states that influence the measured sleep and activity outcomes from wearables, without substantial self-report bias or confounding by unmeasured factors.

C3one line summary

Ultra-brief student concern texts analyzed with NLP associate with lower physical activity during academic concern weeks and poorer sleep plus lower heart rate variability during emotional exhaustion weeks, complementing wearable sensing.
