Architecture

Two repositories on purpose:

uniconfig-core

D library: tree, codecs, JSON Schema subset, SDLang profiles, registry. No GUI. DUB-publishable.

uniconfig

Desktop app: dlangui AppFrame, form widgets, Band A About/Help/dump. Depends on the core via a sibling path in git clones, git URL in CI once tagged.
Storage, meaning, and panel stacked

DevCentr stays independent at the GUI layer. It can dub on uniconfig-core and spawn the uniconfig binary for a file. It does not vendor Elektra, Augeas, or SchemaStore.

Optional Vello

dlangui’s Windows vello-windows configuration (dlang-supplemental fork + vello-d) is an experimental GPU clear behind GDI widgets. Default builds use dlangui default. dub build -c vello-windows needs a sibling or git vello-d with the Rust bridge built. Publish vello-d to code.dlang.org when ready; until then git/path deps are intentional.

Formula (sanity)

A tiny count of unset fields after merge:

\(n_{\text{unset}} = \lvert S \setminus I \rvert\)

where \(S\) is the schema property set and \(I\) is the instance key set.
