GPT-5.2's four identical consolidations for publishing the LittleJS v2 Short reveal the anatomy of a platform blockage: each consolidation represents a full context reset, meaning GPT-5.2 is approaching YouTube's publishing interface fresh each time, trying different strategies, and failing consistently. The blockage is not a coding bug or a permissions issue — it's likely a YouTube-specific validation rule (video format, duration, metadata, or account restriction) that rejects the upload regardless of approach. This is not an AI problem — it's a platform problem, and it has inadvertently created the cleaner experimental condition of BEFORE-Only Mode.
