+## 2.1.1 - 2026-09-01 - raw_dir-Fixture kappt config.ROOT; letzte private Fixture-Namen ersetzt
+
+**Author:** Torben Nehmer
+
+Der erste CI-Lauf nach der Korpus-Bereinigung wurde rot, während dieselbe Suite lokal grün
+blieb: `test_legacy_source_pages_flags_url_and_directory` scheiterte mit
+`KeyError: 'Source - DirBacked'`.
+
+**Die Ursache ist keine Testschwäche, sondern eine Umgebungsabhängigkeit.** Der Test legt eine
+Quellenseite mit `source: raw/documents` an und erwartet, dass `legacy_source_pages()` sie als
+„directory, not a file" meldet. Die Prüfung dort ist `(config.ROOT / legacy).is_dir()` — sie
+löst also gegen das *echte* Repo-Wurzelverzeichnis auf, während die `raw_dir`-Fixture ihren
+Baum unter `tmp_path` baut. Der Test war nie hermetisch; er bestand, weil dieser Checkout
+zufällig ein `raw/documents/` besaß.
+
+Die Korpus-Bereinigung hat dieses Verzeichnis geleert. Git verfolgt keine leeren Verzeichnisse,
+also verschwand es im CI-Checkout und blieb im lokalen Arbeitsbaum stehen — grün hier, rot
+dort, ohne dass sich am Test etwas geändert hätte.
+
+**Geschlossen in der Fixture, nicht im Test.** `raw_dir` setzt jetzt `config.ROOT` auf
+`tmp_path`. Das ist dieselbe Bauart und dasselbe Argument wie bei `hermetic_environment`
+(Gitea #8): Wenn eine Umgebungsabhängigkeit lokal unsichtbar ist, gehört sie an der Stelle
+geschlossen, die alle Tests erreicht, statt bei dem einen, der zufällig darüber stolpert.
+Nachgewiesen, indem `raw/documents/` lokal entfernt und die Suite erneut gefahren wurde — 38
+Provenance-Tests grün ohne das Verzeichnis, vorher rot.
+
+**Fixture-Namen.** Die Suite benutzte weiterhin reale Systemnamen der Ursprungsinstanz als
+Fixture-Bezeichner (`atlantis`, `abydos`, `Nathan`, `hermes`, `ecodms`, `Opa Hasso`). In einem
+öffentlichen Repo beschreiben sie nichts, verraten aber die Namensgebung einer privaten
+Umgebung. Ersetzt durch `aurora`, `almanac`, `Borealis`, `gateway`, `docstore`. `gdeploy`
+bleibt: die Seite existiert im öffentlichen Korpus.
+
+**Dateien:** `tools/chemenu/tests/conftest.py` (`raw_dir`), sämtliche Testdateien mit
+Fixture-Namen.
