Direct Answer: Diversification is how you change the shape of the chain. Dual-source the critical sole-source. Nearshore when distance is the clock. Stock only the gap between alternate lead time and appetite. Leave non-critical singles alone.

- Two tier-1s on one tier-2 die is not diversification.
- Inventory in the same flood plain as the plant is not a buffer.
