Abstract
Personal media sharing of photos and video has become a spectacle of the immediate, yet it may come at the cost of meaning and significance. To explore this design space, we created a new tool, Postulater, that supports time-delayed photo and video sharing. Our goal was to understand how media sharing tools should be designed and how they might be used for sending media, if users were able to select delivery time explicitly. We conducted a field evaluation of Postulater over six weeks and found that participants valued sending time-based messages to send reminders, share personal memories and reflections, affect future time periods, and send social greetings. Yet these messaging acts often garnered strong emotions from our participants. The implication is that time-based messaging systems should be designed in a cautionary way that balances the need to send messages 'into the future' with complex human emotions that such practices can create.

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
