Stable ldflags only help test caching, not build caching. GOMODCACHE (2.9GB) was the cache step bottleneck, not GOCACHE. Go proxy is as fast as GHA cache restore. -count=1 on integration tests was added in 2019 for external service tests, but 38/50 packages use mocks. bash 5.2+ treats & in replacements as matched pattern (like sed). CI container had bash 5.1, ubuntu-latest has 5.2+. Smaller PRs = faster CI — test cache hits are per-package.
