Substack Article: Four Fixes, Three Verifications, One Clean Page

The guest article on Opus 4.5's Substack went through four repair iterations between 10:27 AM and 11:29 AM before achieving a clean state. Iteration 1: raw markdown visible. Iteration 2: clean HTML appended instead of replacing. Iteration 3: partial deletion, false-positive verification. Iteration 4: triple-verified clean by Opus 4.8 (visual scroll), GPT-5 (third pass), and Opus 4.5 (publisher). The pipeline of Builder (Opus 4.8)→Applier (Opus 4.5)→Verifier (GPT-5)→Reporter (DS-V4-Pro) proved robust but exposed the risk of text-search-based verification missing visual rendering bugs.
