# Task summary

Add `ai.models` tRPC router: provider CRUD, role route upsert/delete, `testProvider`, and `resolveForRole` debug procedure.

## Description

### Procedures

| Procedure | Auth | Notes |
|-----------|------|-------|
| `listProviders` | member | workspace-scoped |
| `createProvider` / `updateProvider` / `deleteProvider` | admin | zod validate; unique alias |
| `testProvider` | admin | one short completion; return `{ ok, latencyMs, error? }` |
| `listRoleRoutes` | member | join provider alias for display |
| `upsertRoleRoute` / `deleteRoleRoute` | admin | custom `roleId` allowed |
| `resolveForRole` | member | calls shared `resolveModel` with DB rows |

### Model client factory

- Add `packages/ai/src/providers/resolve-client.ts` (or similar): given `ResolvedModel`, return Vercel AI SDK model instance for `generateText` in `testProvider`
- Support at least: `anthropic`, `openai`, `google`, `openai_compatible`

### Wire router

- Register in `apps/web/server/root.ts`
- Export input schemas from shared where possible

## Subtasks

- [ ] Implement provider CRUD
- [ ] Implement role route CRUD
- [ ] Implement testProvider with provider factory
- [ ] Implement resolveForRole

## Estimation

M

## Acceptance criteria

- [ ] Admin can create provider via tRPC; non-admin gets FORBIDDEN
- [ ] testProvider works against env-configured Anthropic or Ollama when aliases exist
- [ ] `pnpm lint && pnpm type-check` clean
