## Filter: license

MIT — on the workspace allowlist.

## Filter: types

Ships first-party TypeScript types; part of the tRPC v11 adapter suite.

## Filter: maintenance

Active. Maintained by the tRPC team as part of the v11 TanStack Start integration.

## Filter: boundary-fit

Core package. Required for the TanStack Start provider (`core-trpc/tanstack`). No boundary rule violation.

## Filter: shadow-check

No duplicate TanStack adapter in the workspace. No shadow.

## Filter: eu-residency

Client-side integration adapter; no vendor data transmission. n/a.

## Filter: cve-scan

No advisories at adoption time.

## Filter: named-consumer

`core-trpc` exposes a TanStack Start provider via `@trpc/tanstack-react-query` for `apps/web-tanstack`.

## Prompt: replaces

Nothing — this is the initial tRPC scaffold.

## Prompt: migration-cost-out

Hard: the TanStack provider is shaped around this adapter's API; replacing requires re-implementing the provider.

## Prompt: alternatives-considered

This is the official tRPC adapter for TanStack Start. No viable alternative exists.
