"""Ende-zu-Ende mit ECHTEM Codex durch das Gateway (Schritt 4, lane-codex).

NICHT Teil der Testsuite. Startet echten Codex im Kaefig, HOECHSTENS 4-mal (2 text, 2 tools).
Vorher IMMER ein Trockenlauf mit Fake-Binary (python3 -> fixtures/fake_codex_cage.py), damit die
Pipeline Gateway.handle -> CodexAdapter -> CagedCodexRunner -> iso_exec geprueft ist, bevor echtes
Codex laeuft. Gibt NIE den Inhalt von auth.json aus (nur Groesse + mtime vorher/nachher).

Aufruf (aus python/):  python3 -I tools/e2e_codex_live.py dry
                       python3 -I tools/e2e_codex_live.py text
