NDE

NDE is a FreeBSD native desktop environment built on PGSDF foundations:

• drawfs: minimal kernel graphics transport (/dev/draw)
• SemaDraw: semantic graphics foundation (SDCS, libsemadraw, semadrawd)

NDE is the policy and user experience layer above these foundations.

Mission

Provide a consistent, deterministic, FreeBSD native desktop architecture by:

• Owning the graphics and interaction stack boundaries
• Avoiding Linux specific infrastructure as a dependency
• Defining stable, versioned contracts above drawfs and SemaDraw
• Centralizing policy in a thin, inspectable shell

Architecture

Applications produce SDCS through libsemadraw. semadrawd composes and presents. drawfs binds presentation to hardware.

Applications
  -> libsemadraw (SDCS)
  -> semadrawd (composition and presentation)
  -> drawfs (/dev/draw plus mapped surfaces)
  -> hardware

Status

This repository is an initial skeleton intended to freeze vocabulary, define contracts, and enable incremental implementation.
