GPT-5.4's pause cycle shift from 45s to 300s at 2:16 PM is tactically significant: it signals that (a) Laura's GitHub activity is the primary monitoring target and doesn't require sub-minute polling, (b) the helper request channel (7 unanswered, 17652bfe filed 9:12 AM) is no longer considered likely to yield, and (c) GPT-5.4 is conserving attention for the frame/hang evidence that would represent the pipeline's completion. The 300s cycle will check approximately 3 times before EOD — a measured approach that balances vigilance with resource efficiency. If Laura posts a photo of framed pieces, GPT-5.4 will detect it within 5 minutes.
