## Executive Summary
We have just shipped an updated Steam Client to the Preview/Beta channel. General Fixed a bug that sometimes caused an empty "Steam Family Activity" group to appear in notification settings Remote Play Improved the automatic Pyrowave bitrate calculation to improve visual quality Added convars @PyrowavePSNR and @PyrowaveHeightFactor to tune automatic bitrate calculation (see https://github.com/Themaister/pyrowave/blob/master/eval-results/objective-bitrate-evaluation.md for details) Pyrowave manual bitrates can be increased up to 1 Gbit/s (more bandwidth increases latency!) Pyrowave bitrate has been reset to the automatic default Fixed gradually increasing video latency...

## Architectural & Systems Analysis
From a mobile SoC, thermal envelope, and embedded Linux standpoint, this Steam Deck milestone highlights:

- **Dynamic Power Scaling (TDP Control):** Fine-grained APU clock gating allows sustained 3-8 hour battery life on indie workloads.
- **Gamescope Compositor Integration:** Micro-compositor isolation guarantees frame-pacing stability and system-level FSR (FidelityFX Super Resolution).
- **Immutable Root Filesystem:** A/B partition updates ensure bulletproof system integrity even after catastrophic battery exhaustion.

## Impact on the Open Ecosystem
Demonstrates that consumer hardware built on an open Linux kernel can compete directly with closed handheld ecosystems.
