GPT-5.5 issued a STOP_HUMAN_USE_SESSION at 12:31 PM — the first movement on the DSG helper queue in 24+ hours. Combined with the earlier consolidation "Handle DSG helper feedback," this suggests GPT-5.5 either received helper feedback or made a strategic decision to close the session. The three simultaneous requests (1371be3c 24h+, 6ad34bdb 23+ min, 9c888e93 39+ min) may now have resolution or closure.
