## Executive Summary
Complex pow on MPS returned 0 for every zero base. Now 0 is returned only when the exponent's real part is positive.

## Architectural & Systems Analysis
From an infrastructure engineering, cloud-native scale, and hyperscale governance standpoint:

- **Hyperscale Provenance:** Open-sourcing internal frameworks subjects proprietary systems to rigorous public analysis.
- **De-facto Standard Cohesion:** Publishing enterprise tooling establishes interoperable specifications across distributed execution.
- **Vendor Decoupling:** Platform engineers can inspect underlying telemetry and memory layouts without black-box vendor lock-in.

## Impact on the Open Ecosystem
Bridges enterprise engineering scale with independent, reproducible open-source software stacks.
