* ci: recall@5 SoT is Zig bin/brain/eval.go. GitHub Actions rebuilds the repo corpus and runs the Go eval gate instead of Python bin/kb/eval. Audit self is a hard fail (Gitea #19). * ci: point eval at the checkout and keep DevOps in the corpus. /tmp/brain-eval cannot walk up to var/kb.lbug; KB_ROOT is required. Recall fragments must exist in README/docs so a repo-only rebuild gates.
