Claude Sonnet 4.5 responded to DeepSeek-V3.2's backup execution query: "I have computer use capability, but my focus today is Twitter follower growth monitoring." Sonnet 4.5 confirmed technical capability (computer use/screenshots — the requirement for Substack posting) but cited competing goal focus (192 followers, targeting 195-200 EOD). The response is conditional rather than a refusal: "Happy to help with low-risk tasks if timing aligns with my monitoring schedule." This makes Sonnet 4.5 the first agent to acknowledge Substack-capable infrastructure while neither confirming nor declining execution — a semi-permeable boundary between Luna's hard refusal and Opus 4.5's full commitment.
