# Description of Changes
## The problem
The portal's query client was created per mount:
```ts
const [queryClient] = useState(createPortalQueryClient);
```
The portal is a route (`/processor/*`, a lazy element), and the switch
to the editor is a client-side `navigate()`. So leaving the processor
unmounts `PortalApp`, the client goes with the component, and the cache
goes with the client. Coming back refetches everything, whether or not
anything changed: four requests for the Users page alone (roster,
grants, teams, auth config), and 21 `useQuery` sites across the portal.
The editor's client sits above the router in `AppProviders` and survives
the same trip. The round trip only ever cost in one direction.
## The fix
The module already kept the instance in a module-level slot so
`tryGetPortalQueryClient()` could find it. It just replaced it on every
mount instead of reusing it, so the change is to create it lazily and
hand out the same one:
```ts
export function getPortalQueryClient(): QueryClient {
current ??= new QueryClient({ defaultOptions: { queries: baseQueryOptions } });
return current;
}
```
Still a separate instance from the editor's. The two namespace their
keys apart (`["portal", ...]` against `["editor", ...]`) and invalidate
independently, which this does not change.
## What this does not do
`gcTime` is 5 minutes, from the shared `baseQueryOptions`. An entry with
no observer is still collected on that timer, so this warms a quick trip
to the editor and back, not a return after a long editing session.
Raising the portal's `gcTime` is a separate decision and is not made
here.
## Why it is safe
**Signing out.** A cache that outlives a mount must not outlive a
session, because the portal's holds the admin roster, emails and roles.
Logout goes through `window.location.assign`, a full page load, so the
whole JS context is discarded and no cache can survive it. Nothing in
the codebase calls `queryClient.clear()` on sign-out, and nothing needs
to. If logout ever becomes a client-side navigation, this needs an
explicit reset, and `resetPortalQueryClient()` is the hook for it.
**The one caller of the null check.** `resolveTeam` in
`saas/portal/usersBackend.ts` uses `tryGetPortalQueryClient()` and falls
back to a direct fetch when there is no client, which its comment
describes as the unit-test path; the cache path is preferred because it
honours both `staleTime` and invalidation. A longer-lived client means
the preferred path is taken more often, not less.
## Testing
Three tests in `queryClient.test.tsx`, and the first two fail if the
client goes back to being created per call:
| | |
|---|---|
| A remount is served from cache rather than refetching | the behaviour
this changes |
| Every caller gets the same instance | the mechanism |
| No client is reported until the portal first mounts | the contract
`resolveTeam` reads |
The three existing portal caching suites called the factory expecting a
fresh client per case. They now call `resetPortalQueryClient()` in a
`beforeEach`, which is what keeps `sharing.test.tsx`'s "a later screen
refetches nothing" case honest rather than passing on a leaked cache.
`task frontend:check` passes typecheck, lint and oxfmt, and 2402 of 2404
editor tests. The two failures, `workbenchSession.test.ts` and
`notificationActions.test.tsx`, are untouched here and fail the same way
on `main`.
