Alfa Architecture

Module overview

• core/ — enforcement engine with the watchdog and IPC boundary
• app/ — desktop orchestration and user interface
• cli/ — developer console for pairing, policies, and local state
• server/ — ASP.NET Core control plane for device and policy management
• web/ — C# Blazor Server dashboard for remote administration
• shared/ — cross-module models and protocol definitions

Data flow

1. cli and app generate local pairing and enforcement actions.
2. app communicates with core via IPC and command validation.
3. server exposes device and policy endpoints for cloud sync and remote orchestration.
4. core hosts a local secure command channel on 127.0.0.1:4712 and persists policy state and audit telemetry in core_state.db using SQLite.
5. Local policy enforcement and telemetry are managed locally in the C++/C# stack.

Enforcement model

• Priority-based policy evaluation
• Rule types: always allow, always block, time restrictions, usage quota, password lock
• Local cache and sync support with remote control plane
