> h2. Summary
> Opening a Host Summary page by clicking a component count on the Hosts List
> page (or a service's component-count link, or a stack version's host-count
> link) could leave the Host Summary page stuck without its host components
> listed, or with a stale/unfiltered view. Root cause: these links used
> URL-param routes ({{{}/main/hosts/component/:componentName{}}},
> {{{}/main/hosts/version/:versionName/:versionStatus{}}}) that remounted the
> Hosts List component on every navigation, discarding in-flight state and
> racing the data fetch against the route change. Several related bugs stemmed
> from the same remount and stale-closure issues.
> h2. Changes
> * Replaced the URL-param-based filter routes with a new
> {{useHostsFilterNavigation}} hook that sets the Hosts List filter via the
> shared filter context and navigates to the plain {{/main/hosts}} route (no
> route params, no remount). All component-count and stack-version-count links
> across the service summary views and the Stack Versions page now use this
> hook instead of building a {{/main/hosts/component/...}} or
> {{/main/hosts/version/...}} URL.
> * Removed the now-unused {{hosts/component/:componentName}} and
> {{hosts/version/:versionName/:versionStatus}} routes.
> * Fixed a stale-closure bug in {{{}useHostConfigUpdater{}}}:
> WebSocket-driven host/component/decommission updates read host models from a
> snapshot ref that could be one render behind, occasionally overwriting fresh
> data with stale data. Updates are now applied via functional {{setState}} so
> they always merge into the latest committed state.
> * Fixed the Host Summary page's loading spinner staying stuck: it was gated
> on the cluster-wide component poll (which can lag on a large cluster) instead
> of on the host's own loaded data.
> * Fixed the Hosts List filter search bar silently wiping filters that were
> set by another page: it was echoing its local filter state back into the
> shared setter on every render, which could stomp a filter that had just been
> seeded by a deep link.
> * Fixed the Hosts List query no longer sending an unfiltered request on
> first render when filters were already restored from a previous page.
> h2. Impact
> Component-count and version-count links from service summaries and the Stack
> Versions page now reliably open a correctly filtered, fully-populated Hosts
> List / Host Summary page, with no stale data or missed component listings
> caused by the previous remount-based navigation.
