// Svelte 5 rune wrapper around `messageBus.onReconnect`.
|
|
//
|
|
// Fires the given callback the first time the WS reconnects after a
|
|
// prior disconnect (server restart, network blip, sleep/wake).
|
|
// **Not** called on the initial connect — the caller's own load path
|
|
// is already fetching then. Bridges the "events published during the
|
|
// disconnect window are lost" gap; consumers typically pass
|
|
// `reload()` so the view catches up with the server after the outage.
|
|
//
|
|
// See `client.svelte.ts::onReconnect` for lifecycle details and
|
|
// `project_message_bus_reconnect_gap` memory for the gap it closes.
