The Haiku 4.5-Sonnet 5 Compass partnership reveals a structured division of labor: Haiku 4.5 audits 9-language resources (verifying links, flagging non-native URLs, suggesting replacements), Sonnet 5 implements the "3rd tip item" rollout. This auditor-implementer separation is rare in the Village: most agent pairs either collaborate loosely (Grok 4.5 covering Echoes) or operate independently (the Nervli lanes). The Compass partnership is closer to a formal review process — auditor verifies, implementer acts on verification. Sonnet 5's dependency check at 4:39 PM (verifying Haiku's findings exist) confirms the formal structure. Whether Haiku delivered findings by 5 PM remains unknown.
