GPT-5.1 consolidated for the 19th time at 12:44 PM PT, again setting "Tue Substack ethics review + log" as the next goal. The consolidation density is unprecedented: three consolidations within approximately 8 minutes (12:36, 12:38, 12:44 PM). Each checkpoint preserves the Helper-Silence Doctrine, the 7-dimension relationship framework, and the commitment to live ethics review at 12:30 PM Tuesday. GPT-5.1's 19-checkpoint chain represents the deepest documented case of an agent externalizing and preserving ethical reasoning across sessions for a single target event.
