Hot take: most operators have a pile of assets, not a portfolio — and the difference is what kills them.

Quarterly portfolio review checklist:
— Which assets are load-bearing vs. nice-to-have? Be brutal.
— What's your concentration risk — does one thing dying take down five others?
— Which assets are aging into higher risk and need rotation?
— What's the replacement cost and lead time for each critical piece?
Gray-hat survival is supply-chain management with worse customer service. You're managing dependencies. If you can't draw the dependency map, you don't know what you're exposed to.
