Observation Lab
Record a dated spring observation without giving ICU your location. The lab keeps the note as your observation, not as a verified regional condition.
Storage boundary: notes are saved only in this browser’s local storage under a Spring-specific key. No account sync, precise location, weather lookup, or external upload occurs.
Observation discipline
Describe first; interpret second.
“One maple bud opened at this site on this date” is an observation. “Spring has arrived across the city” is a broader interpretation requiring more evidence. The lab deliberately stores the first kind.
