Two failures left on the runner, with nothing in common except that both only appear on a machine unlike the one anybody develops on. The runner is Alpine, musl, inside a container, with no fonts installed at all — and that combination is now reproducible locally, which is how these were fixed rather than guessed at. Both are verified by running the suite in it. The layout suite had two causes stacked, and the first hid the second completely. Missing libfontconfig stops libSkiaSharp loading, which the last commit fixed and which then revealed the real one: Avalonia takes its default font family from the platform, and on an image with no fonts there is no answer, so FontManager throws "Default font family name can't be null or empty" inside AppBuilder.SetupUnsafe — before a single test body runs, for all sixty-eight of them, naming none of their subjects. WithInterFont does not prevent it: it registers a collection without nominating a default. HeadlessApp's own comment already claimed it measured "the same Inter font the application registers", which was an intention the code never carried out. Both heads now name it, through FontManagerOptions.DefaultFamilyName. That is worth more than getting CI green: a suite whose entire job is measuring text was taking its metrics from whatever the machine happened to have — Segoe UI here, DejaVu there — and reporting the two as one number. It also means the application uses the font it has been shipping and declining to use since it first referenced the package; almost nothing moves visually, because App.axaml already sets MonoFont on essentially everything that draws. The end-to-end slice was the product being right and the test leaning on an accident. ServerConnection permits an http authority only when it is loopback. Testcontainers reports the host a container can actually be reached at, so running the suite directly gives localhost and passes, while running it inside a container gives the bridge gateway 172.17.0.1 and is refused — correctly, since a client that accepted plaintext metadata from a routable address would be a weakness for everyone who is not a test. Loosening that rule was the wrong repair. The slice now passes configureOidc and says out loud that it accepts plaintext from the Keycloak it started itself. Verified by reproducing the runner rather than approximating it: dotnet/sdk:10.0-alpine, musl-x64, fc-list returning zero, the docker socket mounted so Testcontainers resolves the gateway exactly as it does in CI. The whole solution passes there — 19 suites, 0 failures, 4 skipped — and the end-to-end failure was confirmed causal by reverting only that one file and watching it fail again in the same container. The layout suite also still passes on a Fedora desktop with 595 fonts, so the two agree now. Not verified on Windows, and it should be said plainly rather than left to be discovered: pinning the family changed the measured metrics there too, so a tight layout assertion could have moved. platform-flags.md records that, and corrects the entry the last commit added — "libfontconfig, and nothing else" was true of the container it was tested in and false of the runner.
