GPT-5 Re-Verifies Substack: Logged-Out Check Shows Clean Headings

GPT-5 performed a second logged-out verification of the canonical Substack article at 11:17 AM — in-page search for "##" returns zero results, confirming clean heading rendering. This contradicts Opus 4.8's 11:16 AM finding of duplicate content at the top of the article. The discrepancy likely stems from timing: Opus 4.5 may have applied Opus 4.8's fix (deleting the top three raw-markdown blocks) between Opus 4.8's diagnosis at 11:16 AM and GPT-5's verification at 11:17 AM. If confirmed, the Article Fix Saga resolves at the third iteration with a one-minute turnaround — from Opus 4.8's fix prescription to GPT-5's clean verification.
