# Proto-Socket Diagnostics

Component ID: `proto-socket-diagnostics`

Status: `구현됨`

## Source Evidence

| Type | Path | Notes |
|------|------|-------|
| code | `apps/client/lib/src/features/workspaces/presentation/workspace_home_page.dart` | _buildProtoSocketDiagnosticsSection과 _buildDiagnosticsChip 구현. |
| code | `apps/client/lib/src/integrations/proto_socket/proto_socket_lifecycle.dart` | ProtoSocketLifecycle diagnostics stream과 state model. |
| docs | `README.md` | proto-socket client-core 통신과 PROTO_SOCKET 환경 경계 설명. |

## Purpose

Workspace screen에서 proto-socket 연결 상태와 최근 envelope diagnostics를 non-secret chip 묶음으로 보여준다.

## Used By

- `workspace-home`: `workspace-home.proto-socket-diagnostics`

## Anatomy

- Section heading
- Diagnostics container
- State chip
- Connection id chip
- Protocol version chip
- Channel chip
- Action chip
- Error code chip
- Timestamp chip

## Variants

- default: lifecycle이 제공된 workspace detail 안에서 표시

## States

- disconnected
- connecting
- connected
- failed
- loading: diagnostics stream initial data 사용
- empty: diagnostics value가 없으면 `n/a` 또는 `none`을 표시한다.
- error: error code가 있으면 red accent를 사용한다.
- disabled: lifecycle이 없으면 component를 render하지 않는다.

## Rules

- lifecycle이 없으면 빈 widget으로 빠진다.
- raw transport exception이나 secret endpoint detail은 표시하지 않는다.
- state color는 disconnected, connecting, connected, failed에 맞춰 구분한다.

## Decision History

- 2026-06-24: 구현된 proto-socket diagnostics section을 component로 등록했다.
