## Executive Summary
Upgrade ACP SDK and derive to the published 3.2.0 release and use its prepared requests/cancellation handles to register new sessions before processing their first updates. Previously, session/new used an ordinary response future. A peer could reply and immediately send an update before foreground session registration, causing the update to be discarded as belonging to an unknown session.

## Architectural & Systems Analysis
From a desktop application, client performance, and user-space engineering perspective:

- **Local-First Computation:** Workloads prioritize client-side execution, eliminating mandatory surveillance telemetry.
- **Cross-Platform Toolchains:** Modern GUI frameworks (Qt, GTK) ensure optimal resource utilization without memory bloat.
- **Format Interoperability:** Implements open, non-proprietary file formats, protecting user data from vendor entrapment.

## Impact on the Open Ecosystem
Safeguards everyday workflow productivity within a trustworthy, zero-telemetry free software ecosystem.
