# Hi-fi: S08 Diagnostic · Diagnostic · intro

> Generated by `botgumi-design index` from `../../screens.json`. Edit that file, not this page.

Stage: **hifi** · Key: `diagnostic/diag-intro` · Data-binding map: [bindings.md](/design/hifi/s08/bindings/index.md)

Drawn in the gallery: [Diagnostic](/design/gallery/index.html#g-diagnostic). Each board is the committed HTML in `screens/`, drawn on the example data in `docs/api/examples/`.

## Contract

- **default**: What will happen (~3 min): read → retell (90 s) → result, in the chosen practice language. States it's real and free.

Flows: F1 First launch → diagnostic → paywall → first real session.

Reads and calls:

- `POST /v1/onboarding → {diagnostic_session, article}`

Local state:

- none

## Boards

One row per state. A state without boards of its own says what shows it.

| State | Board | Example data |
|---|---|---|
| default | [zh-Hans](/design/gallery/diagnostic/diag-intro--default.html) · [en](/design/gallery/diagnostic/diag-intro--default.en.html) | onboarding-answers.json ([zh-Hans](/design/examples/zh-Hans/onboarding-answers.json) · [en](/design/examples/en/onboarding-answers.json)) |
| loading | [no board of its own](/design/hifi/s08/bindings/index.md#states): From [states.md](/design/states/index.md) (Diagnostic intro): skeleton until `/onboarding` returns |  |
| empty | [no board of its own](/design/hifi/s08/bindings/index.md#states): From [states.md](/design/states/index.md) (Diagnostic intro): n/a |  |
| error | [no board of its own](/design/hifi/s08/bindings/index.md#states): From [states.md](/design/states/index.md) (Diagnostic intro): Retry · fatal: generic error |  |
| offline | [no board of its own](/design/hifi/s08/bindings/index.md#states): From [states.md](/design/states/index.md) (Diagnostic intro): "Connect to start" (the diagnostic is server-assessed) |  |

### The boards

Each state as drawn (393 × 852), one board per locale. Open a board on its own for its spec panel.

tested type size and every bound element.
