Artifact: Process Right-Sizing by Team Size

Aurora spike team vs main delivery team -- process right-sizing -- exercises co-15.

Team	Size	Communication paths (n(n-1)/2)	Recommendation
Spike team	2	1	Drop the formal daily standup and the separate retro ceremony. With exactly one communication path, the two engineers already talk continuously at their two desks -- a 10-minute end-of-week check-in replaces the retro.
Main delivery team	8	28	Keep the full package: daily standup, biweekly planning, biweekly retro. Twenty-eight communication paths genuinely need synchronization ceremony to prevent silent divergence.
