ICC 0.1.2 — Windows / PSU 2026.3.3 community preview

Incident Command Center (ICC) demonstrates PowerShell Universal's Model Context Protocol (MCP) feature through an incident rehearsal at fictional Acme Inc. An external assistant discovers and calls ICC_Demo_Incident; PSU executes the PowerShell and saves the acknowledgment. The native dashboard shows the same state. Signals are synthetic, and acknowledgment does not repair a service.

ICC 0.1.2 is a community preview for Windows with PSU and Devolutions.PowerShellUniversal 2026.3.3. It corrects three issues found in the independent 0.1.1 review:

• Coordinate timeline readers and action writers, and return each action's coherent saved-state snapshot.
• Refuse to recreate a missing acknowledgment when retained actions show one existed; explain backup recovery and partial-save failures.
• Show accurate Verify/Open-read messages before an acknowledgment exists.

Validation of 0.1.2 is offline only, on Windows with PowerShell 7.6.6: core 28 checks, MCP backend 8, installers 216 across 71 scenarios, workflow 17, and state/recovery 47 across seven cases. The live native app, signed-in MCP/model workflow, installation and visual acceptance have not been rerun for 0.1.2. Prior live results and the retained screenshot describe 0.1.1. Other platforms, clients, custom identities and multiple nodes remain untested.
