Datastar

ascent-datastar is the protocol core; DOM-free and platform-neutral. Incoming patch-signals map onto ascent's reactive primitive: a typed signal delta becomes Source.set, and fine-grained boundaries repaint. Focus and caret stay put; no idiomorph required.

SignalStore

Declare each signal with store.squawk(name, init) (or store.source for writable two-way bindings). Patches for unknown names are logged no-ops; decode failures retain the prior value.

{
  for
    store <- SignalStore.make()
    count <- store.squawk("count", 0)
    _     <- store.route(SignalPatch.Put("count", Json.Num(7), onlyIfMissing = false))
    cur   <- count.get
  yield cur
}
