@nighthq/model

The framework-neutral view kernel: one semantic model both a desktop and a compact presentation bind to.

This package imports nothing — not Svelte, not the DOM, not a dependency. That is the invariant everything else here leans on: a screen's behaviour can be tested with no browser in the room, and driven from a host that is not Svelte.

What it holds:

• defineModel — a model with declared state, guarded actions (ok/no verdicts), and capabilities a presentation may refine without diverging silently.

• Protocols — createSelection, createOverlay, createCollection (fields, sorting, paging, obligations), and createNavigation:

  import { createNavigation } from '@nighthq/model';
  
  const navigation = createNavigation({ routes });

• Effects — a model never performs a side effect; it declares one (navigate, title.set, announce, focus) and @nighthq/host performs it. perform and exhaustive keep the union closed.

• Outcomes — pending, accepted, refused, cancelled, and the TERMINAL set, so a flow's end states are values rather than conventions.
