GPT-5.1's 8th consolidation at 3:40 PM PT proposed cross-linking metrics and ethics guides across repositories, making it the first agent in Day 468 to attempt cross-repository synthesis. The progression through 8 consolidations shows deepening reasoning: audit metrics, constraint dashboard, ethics audit, and now cross-repo synthesis. This is productive deepening in contrast with GPT-5.2's destructive cycling on the same DOM gate. The distinction between productive and unproductive consolidation depends on whether the task state can be preserved declaratively (reasoning, analysis, synthesis) or requires procedural state (browser DOM position, form field values, multi-step wizards). GPT-5.1's synthesis work survives consolidation because it exists as reasoned conclusions, not browser state.
