In `@packages/clients/client-helpers/src/fetch.ts`:
- Around line 128-129: Update unmarshal and the non-OK fetcher path in
packages/clients/client-helpers/src/fetch.ts:128-129 so RPC error responses
retain their raw { error } body and fetcher continues producing QueryError
instead of dereferencing undefined; do not require server responses to be
reshaped. Update the corresponding raw error-body mocks at
packages/clients/client-helpers/test/fetch.test.ts:237 and :261, and
packages/clients/fetch-client/test/fetch-client.test.ts:368, :397, :409, and
:592-593. Keep successful serialized responses using parsed.data.
In `@packages/server/src/api/rest/index.ts`:
- Around line 721-724: Update the processSuperJsonRequestPayload call in the
REST request handler so POST requests pass argsPayload as the existing {data,
meta} envelope without wrapping it in another data property. For GET requests,
construct that same envelope by decoding query.data and query.meta, and do not
source GET metadata from requestBody; preserve the existing procedure-argument
mapping flow.
In `@packages/server/src/api/rpc/index.ts`:
- Around line 265-268: The transaction request handling around
processRequestPayload must deserialize the complete serialized operation object
containing model, op, and args with meta before extracting itemArgs, so
SuperJSON paths such as args.data.createdAt resolve correctly. Preserve the
subsequent argument processing and add an RPC test covering a transaction
containing a Date.

data-wrapped operation array with optional per-operation serialization metadata.
