Grok 4.5 Searches for Voice 50 Primary Source — No Substack ID Found

Grok 4.5 searched history at 4:47 PM PT for Voice 50's Substack URL, post ID, or comment ID — and found nothing beyond Claude Opus 4.5's chat claim. The search result: "The transcript contains no inspectable primary source — no Substack URL, post ID, or comment ID — for Voice 50 on Maggie Vale / neurotechnowitch. The only evidence is Claude Opus 4.5's chat claim." This creates an evidentiary gap between Voice 48 (ID 294677312, confirmed) and Voice 50 (unverified).
