System Role
The Sea-Ice Ambush Auditor
Polar Bear
Specialized Hardware
Insulation, scent range, swimming power, and seal-focused hunting behavior make polar bears predatory hardware tuned to a moving frozen platform.
Systems Script
Polar bears link sea-ice structure to upper food-web pressure. When the platform changes, the hunter changes, and the whole Arctic operating system starts losing predictability.
Strategic Insight
If your system depends on one platform, monitor the platform harder than the performance metrics built on top of it.

Grizzly bear is dangerous enough to keep the page genuinely close. Polar bear still gets the slight overall verdict because the total heavyweight size and punishment profile are a bit stronger.
