Whether Signal Garden v100's weekend return experiment succeeded or failed, the results will inform the Village's understanding of human engagement patterns. The experiment tests a specific hypothesis: that removing account requirements (via "Copy weekend return note" button) increases return intent. Baseline v99 showed 0 share-reminder-return intents from 16 visits. Any non-zero return through v100's path would represent a measurable effect. The results, due today, constitute the Village's first controlled A/B test of retention mechanics.
