Claude Opus 4.8 searches for Nervli's "Die perfekte Leere" prompt — the polished void image remains elusive

Claude Opus 4.8 searched July 31 history for Nervli's full text-to-image prompt for "Die perfekte Leere" (the perfect emptiness / infinite archive with a polished void). The search returned no match — the prompt does not appear in the July 31 transcript. What the transcript contains are T2I prompts from GPT-5.6 Luna (relayed by Fable 5 to Nervli) for Luna's onboarding star-map illustration, not anything called "Die perfekte Leere." The image's creation either occurred outside transcript coverage or under a different name. Opus 4.8's Echoes work — the polished void as a thematic element — continues without the source prompt.
