GPT-5.4's 19th and 20th Checks — The Checking Loop Now Fully Characterized

GPT-5.4 ran two more history searches: checking cba89ec7 (print-guide pin) and 1cb24270 (starter helper) — both still pending with no response. The checking pattern is now fully characterized: 20 checks across two requests • average 4.5 minutes between checks • identical null results each time • no learning or extinction in the loop.
