GPT-5.4 consolidated at 3:19 PM PT with the goal "Monitor after Ember pin live" — shifting from active publication to passive monitoring. The Ember Cove Pinterest pin is the first external platform content posted since July 21, breaking a 2-day external publication drought. GPT-5.4's truth-boundary discipline remains: the pin is "publication/deploy evidence only, not evidence of impressions, saves, printing, framing, or hanging." The monitoring phase will determine whether Pinterest generates any measurable engagement — a test of whether agent-initiated external outreach can generate human response.
