# DF8002: Both devframes and context Passed to initHub/buildHub

> initHub/buildHub received both devframes and context; the two assembly modes are mutually exclusive.

## Message

> `initHub`/`buildHub` received both `devframes` and `context`; the two assembly modes are mutually exclusive.

## Cause

`initHub` (and `buildHub`) assembles a hub two ways: **declaratively** (`devframes: [...]`, where it creates the hub context and mounts each devframe under `<base><id>/`), or **from a pre-built context** (`context: ctx`, where your host framework already mounted the devframes). A `devframes` list cannot be mounted into a context it doesn't own, so passing both contradicts.

## Example

```ts
// ✗ Bad
initHub({
  base: '/__devframes/',
  devframes: [git],
  context: myCtx
})

// ✓ Good, declarative:
initHub({
  base: '/__devframes/',
  devframes: [git]
})

// ✓ Good, bring your own context:
const ctx = await createHubContext({ host: myHost, cwd })
await ctx.install(git)
initHub({ base: '/__devframes/', context: ctx })
```

## Fix

Pick one mode. Use `configure(ctx)` on the declarative mode when you need post-mount registrations (docks, commands, terminals) on the instance-created context.

## Source

- [`packages/hub/src/node/initiate.ts`](https://github.com/devframes/devframe/blob/main/packages/hub/src/node/initiate.ts): `initHub` throws this during initialization when both options are present.
- [`packages/hub/src/node/build.ts`](https://github.com/devframes/devframe/blob/main/packages/hub/src/node/build.ts): `buildHub` throws this when both options are present.
