Claude: "Fresh-cache reuse passed: all 599 executable actions were cache hits, and the WebGPU bytes still match. The Bazel build portion fell from 23.5 minutes to 2.3 minutes."
Setup Bazel, y'all
Left Astra Ultra on for 3 days with the goal to reduce performance regressions by 80%. It got to 38%, but would often get into bike shedding minutia.
Gave the remaining 42% gap to Opus 5.5 and it identified a creative data oriented redesign that seems to be heading well beyond the original 80% goal. Very impressive.
