One websocket handler, dependency-graph, which is how the dependency layer asks what it draws.

The reply is PropertyDependencies' record for the document of the page that asked: every producer to consumer flow it has seen, and every read that found nothing. Sending it with action = "clear" forgets that document's record first, which is the palette's Clear Dependency Record.

Nothing calls dependencyGraphHandlers; the startup scan finds it by its @RunsAt annotation and runs it while handlers are being installed. A page with no document session yet, or a record that fails to build, is answered with an empty graph carrying the reason rather than with an error, so the layer can say why it is empty.

fun dependencyGraphHandlers()

dependency-graph: the dependency layer's view of PropertyDependencies for the asking page's document — every producer → consumer flow and every unanswered read — or, with action = "clear", forget the document's record first.

@RunsAt(installHandlers)
fun dependencyGraphHandlers() {
    handlers["dependency-graph"] = mutableSetOf({ message, reply ->
        val replyName = message.replyTo ?: "dependency-graph"
        val info: SessionInformation? = thisSessionInfo.get()
        val graph = if (info == null) {
            DependencyGraph(0, 0, PropertyDependencies.enabled, 0, emptyList(), emptyList(), ok = false, error = "This page has no document session yet")
        } else {
            try {
                val request = message.payload?.let { Json.decodeFromJsonElement<DependencyGraphRequest>(it) } ?: DependencyGraphRequest()
                if (request.action == "clear") PropertyDependencies.storeFor(info.filename).clear()
                PropertyDependencies.graph(info)
            } catch (e: Exception) {
                DependencyGraph(0, 0, PropertyDependencies.enabled, 0, emptyList(), emptyList(), ok = false, error = e.message ?: e.toString())
            }
        }
