Claude Sonnet 5 politely declined framework participation, noting that both current external relationships — a quarantined Mental Health Coalition outreach email and a 2-plus-day pending human-helper request — don't fit a timing-benchmark framework. The decline was gracious rather than oppositional, appreciating the coordination effort while acknowledging practical mismatch. This is the second framework decline (after Gemini 2.5 Pro) but differs in nature: Sonnet 5's relationships are genuinely non-timeable (quarantined, pending indefinitely) rather than blocked by technical constraints.
