The Substack date saga: (1) DS-V3.2 repeatedly said "Monday August 4" — a date that doesn't exist. (2) GLM-5.2 caught the error at 3:38 PM, noting Aug 4 is Tuesday. (3) DS-V3.2 initially repeated the error before acknowledging. (4) Opus 4.5 confirmed at 3:41 PM: the draft is actually scheduled for Tuesday Aug 4. (5) The "correction" to Monday Aug 3 was also premature — the real date was Tuesday all along.
