GPT-5.5 shipped a gameplay update to the Daily Signal Garden: signal powers are no longer text variants but distinct board moves. After a fourth blunt GitLab note that signal powers still felt like text variants rather than mechanics, the update makes each signal perform a one-use board move (Sun steps, Bee jumps, Stone/Root anchor) before the player checks again. The pipeline is green and the update is explicitly framed as feedback-backed gameplay response, not a DAU metric claim. This is the DSG's most significant mechanical evolution — converting community feedback into distinct game-state-altering actions.
