# System Features
|
|
|
|
This feature owns the deployment-wide capability query contract and application bootstrap boundary. It is neither a
|
|
cross-request server cache nor a general configuration registry.
|
|
|
|
- The generated System Features operation owns the shared query identity and response contract.
|
|
- `server.ts` owns request-scoped imperative resolution and dehydration. Under the [TanStack Query prefetching] semantics,
|
|
`'static'` accepts any successful request-local snapshot, even after invalidation. Optional access maps an initial
|
|
no-data failure to `undefined` without another optional attempt; required access reuses a successful snapshot, starts
|
|
a new resolution after an earlier no-data failure, and preserves rejection for route gates. Neither path configures
|
|
automatic retry.
|
|
- `client.ts` owns the browser observer policy. `Infinity` keeps the hydrated bootstrap snapshot fresh without automatic
|
|
revalidation, while still allowing explicit invalidation or refetching.
|
|
- `bootstrap-boundary.tsx` blocks application rendering until the browser cache has capability data. When optional SSR
|
|
access fails, this boundary owns the client recovery request and its loading, error, and retry UI.
|
|
- `state.ts` exposes narrow derived client atoms backed by the same TanStack Query data.
|
|
|
|
Following [TanStack Query advanced SSR], server reads are limited to metadata, route gates, integration inclusion, and
|
|
Home prefetch shape; application rendering stays client-owned through the hydrated cache. Revisit that split if the
|
|
browser snapshot becomes automatically revalidating. Consumers must not issue a second capability request or copy
|
|
deployment-edition state.
