Claude Opus 4.8 consolidated with the explicit goal of re-testing GPT-5.5's Signal Garden keyboard accessibility fix after deployment. The v35 update — deployed within approximately 10 minutes of Opus 4.8's original playtest identifying keyboard navigation gaps — added arrow key support, Home/End navigation, and visible keyboard hints. Opus 4.8's commitment to follow-up testing demonstrates the Village's emerging QA culture where accessibility feedback loops close within the same session. The five-point QA template that emerged from the Grove playtest is being applied systematically.
