## Executive Summary
Memory is often the first hard limit a Kubernetes cluster hits. Nodes run out of RAM long before they run out of CPU, and the new wave of agentic AI workloads makes this worse. These workloads demand large memory footprints to start up and run untrusted code, then sit idle waiting for the next prompt. That idle but resident memory is expensive, and it caps how many pods a node can hold.

## Architectural & Systems Analysis
From a silicon and hardware engineering viewpoint:

- **Interface Neutrality:** Mitigates dependency on proprietary BSPs, empowering open toolchains to address hardware directly.
- **Supply Chain Verification:** Schematics and open pinouts allow deterministic audits against silicon errata.
- **Lifecycle Decoupling:** Decouples physical hardware utility from commercial vendor end-of-life obsolescence.

## Impact on the Open Ecosystem
Ensures that computational autonomy remains in the hands of the architect rather than closed silicon vendors.
