+## 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/`.

 That's the deeper reason these numbers live in a tool rather than in prose: prose is read once
 and remembered loosely, but a threshold enforced every call is tested by every call, and a
 threshold that fails its own test gets noticed and re-measured rather than quietly ignored.
+
+The suite's coverage floor is the same argument run forwards instead of backwards. The ceiling
+above was wrong first and measured afterwards; the floor was withheld on purpose until the number
+existed - measured, then watched across 38 runs while the code grew by a quarter, and only then
+written down as 85 against an observed 87.0%. The two points of daylight are the same
+consideration as the ceiling's headroom: a limit the ordinary case keeps tripping stops being a
+limit. A coverage floor set at the measured number goes red on the next thin command wrapper,
+which is not a regression, and a threshold that goes red for a non-reason gets lowered rather
+than earned - the failure mode above, reached from the other direction.
