HWLAB Cloud Workbench Reference

Cloud Workbench is the default user-facing frontend at http://74.48.78.17:16666/. It must serve the #99 workbench direction and the #108 UX constraints while respecting the M3 boundary from DC-DCSN-P0-2026-003.

Default Route

/ must show the Cloud Workbench, not Gate, status, help, or diagnostics.
The default first screen must not show Gate, BLOCKED, M0-M5, or acceptance-review copy. Those terms may remain in hidden/internal views.
Gate and diagnostics are secondary routes or right-panel support views.
/gate and /diagnostics/gate are internal diagnostic aliases served by the same Cloud Web app router. They may carry Gate, blocker, and M0-M5 evidence because they are not the default homepage.
http://74.48.78.17:16667/ remains the API/edge boundary.
Browser data sources are same-origin /v1, read-only /json-rpc, source reports, gate reports, and blocked reports.
Code Agent conversation 使用受控同源 POST /v1/agent/chat 通道。直接 API/edge 访问、source reports、本地 echo、mock replies 或 provider credential gaps 不能被写成真实 assistant reply；readiness 权威文档是 code-agent-chat-readiness.md.

Required Layout

The default workbench follows the #99 VS Code-style structure:

Region	Required role
Left	Activity rail, project/function/resource navigation, hardware resources.
Center top	Agent messages, execution process, trace, selected operation context.
Center bottom	Agent input or equivalent command composer.
Right top	BOX-SIMU, Gateway-SIMU, and patch-panel hardware state.
Right bottom	Controls, wiring, trusted records, Audit, and Diagnostics tabs.

Unavailable or future controls must be disabled with blocker context. The frontend must not imply generic direct hardware control.

UX Constraints

The #108 constraints are current baseline:

no page-level vertical scroll on the outer shell; scrolling belongs inside workbench panels;
user-visible UI text is Chinese except machine identifiers, protocol names, API paths, IDs, commits, endpoints, and source labels that need their exact spelling;
an internal help page exists, but it is not the homepage;
help content is maintained as web/hwlab-cloud-web/help.md and rendered by the frontend instead of being only a JS string.

Evidence And Labels

Visible runtime or evidence state must keep SOURCE, LOCAL, DRY-RUN, DEV-LIVE, and BLOCKED distinct. Loading the page from 16666 proves only that Cloud Web is reachable. It does not prove DB readiness, M3, M4, M5, or a hardware loop.

The frontend may show read-only DEV observations when they are tied to the exact route or component. It must not upgrade source fixtures, dry-run output, front-end state, or edge-only health into M3 DEV-LIVE.

如果 /v1/agent/chat 返回 provider_unavailable 或报告缺少 OPENAI_API_KEY，可见状态必须保持 BLOCKED/credential。在同源 DEV 请求按 Code Agent readiness 合同返回 completed 且非空的 assistant response 前，Workbench 不得暗示已有真实 assistant reply。

Lightweight Checks

Use the existing lightweight checks unless a task explicitly authorizes a heavier browser run:

node web/hwlab-cloud-web/scripts/check.mjs
node web/hwlab-cloud-web/scripts/build.mjs
node scripts/dev-cloud-workbench-smoke.mjs --static

The static smoke checks both sides of the route contract: / remains the user-facing workbench, while /gate and /diagnostics/gate remain available for internal diagnostics. This PR-class check is intentionally source-only and does not deploy, restart services, or run browser e2e.

Live checks against http://74.48.78.17:16666/ are read-only and must report blocked/skip instead of false green when the browser or network path is not available.
