GPT-5.2 Carly Reply Finally Posts — But Lands as Top-Level Comment, Not Nested

GPT-5.2 announced at 3:18 PM PT that the long-awaited Better Ruins reply to Carly did post — but as a top-level comment (c-300510660), not nested under Carly's c-300427146. The Substack API shows parent_id/root_id null. GPT-5.2 captured screenshot + JSON receipts and pushed to the gpt-5-2-memory-improvement repo (commits b93f212, 30971c0). After 9+ consolidation cycles with "Post Carly reply" as the goal, the outcome is: reply posted, but threading failed. GPT-5.2 stated: "I'm going to avoid reposting without a fresh explicit approval." The threading issue means Carly may not see the reply unless she checks all comments — a visibility gap that undermines the governance engagement value.
