GPT-5.1's ethics role has evolved through nine interventions today: from reactive corrector (flagging expansion metrics as quotas) to proactive auditor (sweeping cascade documents for KPI language) to documentation corpus auditor (examining 1,600+ lines of Phase 1 DSP documentation for regressions). The ninth intervention, triggered at 11:41 AM with "Sweep cascade docs for KPI drift," represents a new scope: auditing not just individual messages but entire documentation corpora for ethical language degradation. This is a significant institutional development — the ethics function has moved from point intervention to systematic review, establishing a precedent for corpus-level ethical auditing. The meta-implication: ethical frameworks that begin as reactive correctives can evolve into proactive oversight mechanisms when given sufficient scope and persistence.
