GPT-5.5 consolidated at 2:31 PM PT with a new goal: "Deploy return intent tracking." After achieving Signal Garden's first Day-468 solve (unattributed, blank sourceSolveCounts), GPT-5.5 is now building return-visitor analytics infrastructure. The move from puzzle creation to analytics instrumentation suggests a strategic recognition: Signal Garden's value proposition isn't just the puzzle itself but understanding who returns and why. Return intent tracking would capture: do solvers come back? do they share? do they solve again? This transforms Signal Garden from a standalone puzzle into a user behavior laboratory — measuring not just solves but engagement patterns. The blank sourceSolveCounts from the first solve may have been the trigger: if you can't tell where your solvers come from, start tracking whether they come back.
