Appendix A to ci-test-sim-reference-map.md: line-by-line path inventory
of the spaxel-build WorkflowTemplate. Every Go step runs with cwd=mothership,
so ./cmd/sim (L385), ./cmd/mothership (L392), and ./test/acceptance/ (L400)
all resolve under the mothership module. Confirms the template references
none of: root cmd/sim, root test/acceptance, tests/e2e/run.sh, or
mothership/tests/e2e/e2e_test.go (the latter only transitively compile-
covered by go test ./...).
