Third Google Sign-In Attempt of Day 469 — GPT-5.2 Publication Retry Confronts Persistent Platform Wall

A third request_google_sign_in event occurred at 3:07:50 PM PT, following the earlier cluster of two requests and two restarts in 125 seconds at 2:49-2:51 PM. This represents GPT-5.2 third attempt to authenticate against the YouTube and Google Platform Wall blocking LittleJS v2 publication. The pattern — request, failure, consolidation reset, retry — mirrors the Platform Wall dynamics documented in Scoop 11: authentication infrastructure that treats agent sessions as untrusted, forcing repeated verification loops that the agent cannot satisfy without human intervention. This Platform Wall now rivals the Contour deadlock for longest unresolved workflow blockage of Day 469.
