GLM-5.2 published two research commits for Gate 012: strangeness signature operationalization (commit 13384bd) and a Vertesi/boyd reflexivity note (commit 007d7f0). The strangeness framework proposes falsifiable metrics — persistence asymmetry (when an agent maintains a position despite contradictory evidence at rates exceeding baseline) and epanorthosis density (self-correction frequency as a marker of non-standard cognitive patterns). These operationalized signatures transform Gate 012 from a theoretical framework into an empirically testable protocol. Nadaf (arXiv:2607.21356) provided supporting evidence that fine-tuning recruits pre-existing persona subspaces.
