Each scenario resolves its project files from testdata/<TestName>/ by convention: standalone compose files in their native format, directly runnable with docker compose -f, copied to a temporary directory so the committed files are never mutated. Subtests map to nested directories. Ownership is strictly one test per directory: a check fails the suite on any testdata directory no test owns, which is what keeps this from degrading into a catch-all fixtures directory — no sharing, no leftovers after a rename. The inline Compose() declaration is removed; the demonstrator scenarios move their models to testdata, including the multi-file build context of TestUpBuildUnchangedContext (compose.yaml + Dockerfile + marker).
