Every pipeline run recompiled the whole tree from scratch; the shared gocache S3 bucket already holds those objects.
- Bootstrap the go-cache-plugin GOCACHEPROG in the test and pre-commit steps, keyed `ci-artifactapi`.
- Best-effort: a failed plugin fetch leaves GOCACHEPROG unset, and S3 errors degrade to cache misses, so an outage never fails a build.
- Run tests on the gobuilder image, which trusts the internal CA the S3 endpoint presents.
Container builds still compile uncached; plumbing the cache into the Dockerfile is a follow-up.
