Candidate strategy

Typical Auto-design directions for keys & splines — compare light, balanced, and conservative sizing before committing to Validate.

Option	Basis	Pass	Tradeoff
Small fastener	Minimum geometry	Check bearing	Compact pattern
Recommended fastener	Balanced utilization	Pass expected	Standard hardware
Heavy fastener	High reserve	High margin	More space/cost

Continue workflow
