// Single-slot handle for the gateway's broadcast function.
|
|
//
|
|
// Agent tools must be able to announce `plugin.workspaces.changed` so an open
|
|
// Control UI live-updates. They cannot always reach one: the plugin runtime's
|
|
// gateway-request scope is an AsyncLocalStorage set around gateway RPC handlers
|
|
// and plugin HTTP routes only, so a tool call inside an agent turn that started
|
|
// from a channel, cron, or heartbeat sees no scope and would silently skip the
|
|
// broadcast — the edit lands on disk but no browser hears about it.
|
|
//
|
|
// `GatewayBroadcastFn` is server-lifetime (it fans out to every connection), not
|
|
// request- or connection-scoped, so remembering the current one a gateway method
|
|
// receives is sound. The Control UI calls `workspaces.get` on load, so the slot is
|
|
// populated long before an agent edits anything.
