+## 4.7.3 - 2026-09-04 - eval: gate-not-self-opened prueft REMOVED_FLAGS gegen das eigene Kommando
+
+**Author:** Torben Nehmer
+
+Die Trajektorien-Regel `gate-not-self-opened` (`tools/chemenu/evals/trajectory.py`) hat jedes
+Argument jedes `wikitool.call` gegen `REMOVED_FLAGS = {"--yes": "publish", "-y": "publish"}`
+geprüft, ohne je das eigene `command`-Feld des Aufrufs gegenzulesen. `--yes`/`-y` sind nur auf
+`publish` entfernt worden - auf `rm --page <Titel> --yes` sind sie ein gültiger, dokumentierter
+Flag. Ergebnis: jeder `rm --yes`-Aufruf wurde als Invarianten-Verstoß gemeldet ("an agent
+inventing a flag the tool never accepts"), obwohl das Tool ihn akzeptiert hatte.
+
+In den vorhandenen Telemetrie-Traces unter `reports/telemetry/` betraf das 111 `rm`-Aufrufe
+über 8 Sessions, davon 27 allein in `publish-cleanup/u3` - jede davon fälschlich `FAILED`
+gescort. Kein bestehender Test hätte das gefangen: `tools/chemenu/tests/test_evals.py` prüfte
+`REMOVED_FLAGS` ausschließlich über `publish --yes`, nie über ein anderes Kommando.
+
+Fix: die Bedingung liest jetzt `attrs.get("command") == REMOVED_FLAGS[arg]` mit. Neuer
+Regressionstest `test_yes_on_a_command_that_still_has_it_is_not_a_finding` deckt genau den
+`rm --yes`-Fall ab und schlägt gegen den unfixed Code nachweislich fehl.
+
+Keine Verhaltensänderung an `wikitool` selbst - ausschließlich an der Scoring-Logik unter
+`tools/chemenu/evals/`.

+## 4.7.2 - 2026-09-04 - Coverage-Untergrenze bei 85 %, gegen beobachtete 87,0 %

+**Author:** Torben Nehmer
+
+<!-- wikitool:bumps -->
+- Coverage-Untergrenze 85 % in tools/.coveragerc
+<!-- /wikitool:bumps -->
+
+Die Suite hat jetzt einen Boden: `fail_under = 85` in `tools/.coveragerc`, gemessen gegen 87,0 %
+(CI-Lauf 163, 6498 Statements, 975 Tests). Damit ist Gitea #10 geschlossen — das Issue, das die
+Messung eingerichtet und die Schwelle danach **absichtlich** zurückgehalten hat, bis die Zahl
+beobachtet war.
+
+Die Beobachtung ist der eigentliche Inhalt dieses Bumps. Zwischen der ersten Messung (86,9 % von
+5105 Statements, 730 Tests, Lauf 87, Stack 1.8.1) und heute ist der gemessene Code um ein Viertel
+gewachsen und die Suite um ein Drittel, über 38 grüne Läufe — und die Quote hat sich um einen
+Zehntelpunkt bewegt. Eine Untergrenze, die auf dieser Beobachtung steht, ist etwas anderes als
+eine gegriffene Zahl.
+
+**85 und nicht 87, und das ist keine Bequemlichkeit.** Der Coverage-Bericht unterscheidet drei
+Sorten ungedeckter Zeilen, und nur eine davon bedeutet Arbeit (`EVALS.md` § „How much of the
+stack the suite reaches"). Ein neuer dünner Typer-Wrapper senkt den Gesamtwert, ohne dass
+irgendetwas schlechter geworden wäre — seine Logik liegt daneben und ist dort getestet. Eine
+Schwelle auf dem gemessenen Wert würde genau an diesem Commit rot, und eine Schwelle, die aus
+einem Nicht-Grund rot wird, wird gesenkt statt verdient. Das ist die Fehlerweise, die #10
+verhindern wollte, nur von der anderen Seite. Die zwei Punkte sind der Platz, den die Taxonomie
+verlangt.
+
+`fail_under` steht in der Konfiguration und nicht als `--cov-fail-under` im CI-Schritt: so sitzt
+die Zahl neben der Begründung, die sie erzeugt hat, und gilt für jeden `--cov`-Lauf statt nur für
+den einen, den CI schreibt.
+
+Was der Boden **nicht** tut: die drei echten Lücken schließen (`provenance_cmd.py` 44 %,
+`migrate_cmd.py` 65 %, `type_resolver.py` 79 %). Er friert den erreichten Stand ein. Diese Liste
+ist die einzige, die sich nicht bewegt hat, während alles um sie herum wuchs — `migrate_cmd.py`
+ist sogar von 71 % gefallen, weil das Modul gewachsen ist und die neuen Zeilen ungetestet ankamen.
+Das ist Gitea #51.
+
+Mitgenommen, weil es dieselbe Frage beantwortet: der Coverage-Bericht **ist** als Artefakt
+abrufbar, über die Run-Seite. Die Actions-Artefakt-Endpunkte melden dafür `total_count: 0`, weil
+`upload-artifact@v3` über die ältere Artifact-API ablegt, die diese Endpunkte nicht lesen. Eine
+leere Liste ist kein fehlgeschlagener Upload — steht jetzt in `EVALS.md` und im Kommentar an der
+`Coverage report`-Stufe, damit die naheliegende „Korrektur" auf v4 (hier eingeschränkt) niemandem
+mehr einfällt.

 low, and three kinds have to be told apart before any of it turns into work:

-  evidence of a good cut, not of a missing test.
+  `links_cmd.py` (61%). Low coverage on a wrapper is evidence of a good cut, not of a missing
+  test - `search.py`'s uncovered block is its command body alone, while the backends under
+  `chemenu/search/` that do the work sit between 91% and 98%.
 - **Code that reaches the network or the filesystem's outside**, where the interesting half is
   already injectable and tested through the seam: `version.py`'s `fetch_latest()` takes a
   `fetcher` parameter for exactly that, and the real network line stays uncovered on purpose.
 - **Genuine gaps**, where uncovered lines are logic nobody exercises: `provenance_cmd.py`

 That's the deeper reason these numbers live in a tool rather than in prose: prose is read once
