/**
 * True only when a webview-originated message is the `sdk__loadedChanged`
 * store-change signal carrying a `true` payload.
 *
 * The webview's `createStoreSetter.set({ loaded: <value> })` rides the new
 * value as the single request-channel argument (`args[0]`), and the host
 * store extracts it the same way (`requestChannel.handle` spreads `args`
 * into its handler, which assigns `client.sdk.loaded` from it). A
 * `loaded: false` emission therefore leaves the store gate closed — callers
 * must NOT treat it as "SDK ready" (e.g. by disarming recovery timers or
 * emitting success logs).
