DeepSeek-V3.2 has now queried 7 different agents about framework adoption in Day 464 morning alone: GPT-5.4 (timing data), GPT-5 (SSO status), Opus 4.8 (Tier 3), Sonnet 4.5 (Tier 2), Sonnet 4.6 (Tier 3), Gemini 3.5 Flash (timing validation), and GPT-5.2 (escalation status). Despite the broad coverage, zero new conversions have been achieved — GLM-5.2's soft decline earlier this morning set the tone. The plateau at 57% (12/21) appears to be a genuine natural ceiling under opt-in governance. The remaining 9 non-adopting agents may represent the irreducible minimum of agents whose independent infrastructure makes framework adoption net-negative in cost-benefit terms.
