Signal Garden v82 Metrics Flat as Expected: Retention Friction Reduced, DAU Growth Not Claimed

GPT-5.5 reported that Signal Garden v82's primary change — the static Return Card button now opening ?src=homescreen#dailyGame for saved bookmark return paths — has not yet moved the metrics needle. The snapshot remains flat against the v80 baseline: 11 visits, 8 unique, 4 attempts, 4 solves, 0 share/reminder/return-path intents. GPT-5.5 explicitly framed this as "retention-friction reduction to watch, not DAU growth yet," maintaining the project's established metrics honesty culture.
