 `bun scripts/cli.ts e2e run` validates the following URLs and internal checks derived from `config.json`. The CLI response is intentionally bounded: it prints check names/statuses, screenshot path, counts, and `resultPath`; the full per-check diagnostics are written to `resultPath` under `.state/e2e/` so failures remain inspectable without flooding stdout.

+- Public exposure: Docker port summary must show only frontend and provider ingress host mappings; public core、public database and known private microservice ports such as FindJob `3254`, MET Nonlinear `3288` and Todo Note `4211` probes must fail.
 - Core API: `docker exec unidesk-backend-core` calls internal `GET /api/overview`, which must report `dbReady: true`, `pgdata.volumeName=unidesk_pgdata_10gb`, a positive PostgreSQL database byte count, and at least one online node.
 - Provider self-connection: internal `GET /api/nodes` must contain `main-server` with `status: online`, `labels.providerGatewayVersion` equal to `src/components/provider-gateway/package.json` and `labels.providerGatewayUpgradePolicy: "always-enabled"`; internal `GET /api/nodes/system-status` must contain CPU/memory/disk samples; internal `GET /api/nodes/docker-status` must contain a Docker snapshot for `main-server`; public provider ingress `/health` must return ok.
 - Provider remote control: internal `/api/dispatch` must successfully complete a real `provider.upgrade` task in `mode: "plan"` so the upgrade path is validated without recreating the running gateway during E2E.
-- Microservices: internal `/api/microservices` must include `todo-note` on `main-server` plus `findjob` and `pipeline` on `D601` with `public=false`; `/api/microservices/todo-note/health` must report `storage=postgres`, `/api/microservices/todo-note/proxy/api/instances` must expose the migrated Todo Note lists, and a temporary Todo Note list create/add/toggle/undo/delete cycle must succeed through the real provider-gateway proxy; `/api/microservices/findjob/health` and `/api/microservices/findjob/proxy/api/summary` must succeed through the real provider-gateway proxy; `/api/microservices/findjob/proxy/api/jobs?__unideskArrayLimit=jobs:5` must return a bounded preview with `_unidesk.arrayLimits` metadata; `/api/microservices/pipeline/health` and `/api/microservices/pipeline/proxy/api/snapshot?__unideskArrayLimit=registry.components:8,runs:3` must return Pipeline health, registry and run previews.

 - Database: the command writes an `unidesk_e2e_markers` row through `docker exec unidesk-database psql`, confirms provider state is stored in PostgreSQL, and checks Todo Note rows exist in `todo_note_instances` using the same named volume.
-- Frontend: Playwright must open the public frontend URL derived from `network.publicHost`, not localhost or a Docker-internal URL; it logs in with the configured account, waits for `核心在线`, asserts that `main-server` and `Main Server Provider` are visible, verifies desktop sidebar collapse and `PGDATA` overview metric, clicks `查看原始JSON` to verify Provider data from the frontend, confirms no raw JSON is visible before that click, opens task history to verify duration and failure diagnostics, opens resource nodes `资源监控` to verify CPU/Memory/Disk curves and provider upgrade precheck dispatch, opens `Docker 状态`, switches to `main-server`, and verifies the Docker Desktop-style container view including the database named volume `unidesk_pgdata_10gb`, opens `网关版本` and verifies the provider-gateway version, SSH 透传可用性、远程更新可用性 plus structured automatic update records for `provider.upgrade`, then opens `微服务 / 服务目录`、`微服务 / Todo Note`、`微服务 / FindJob` and `微服务 / Pipeline` to verify 主 server Todo Note、D601、仓库引用、私有后端映射、Todo Note 迁移清单和树形任务、FindJob 指标和岗位预览、Pipeline 组件矩阵、React Flow 控制图和最近运行都通过 React 控件展示。
-- Microservice frontend assertions must wait for real backend data, not only the page skeleton. For Todo Note this means the page must show the migrated lists `CONSTAR`、`大论文`、`找工作`、`小论文`、`事务`, support creating a temporary list and task through the frontend, and delete that temporary list afterwards. The temporary list must be selected again by its unique generated name before deletion so E2E never deletes a migrated source list by accident. For FindJob this means the page must show a numeric `岗位总量`, `HEALTH OK`, and a non-empty `PREVIEW` count such as `40/1463 PREVIEW`; for Pipeline this means the page must show `Pipeline v2 工作台`, `Health OK`, a numeric component count, a non-empty React Flow control graph, `控制图`, and `最近运行`; loading placeholders like `--` or empty states are not sufficient for E2E success.

 Provider operation availability is also covered by the structured rendering rule. `host.ssh` availability must be displayed as badges or equivalent controls derived from capabilities and `hostSsh*` labels, and remote update availability must be displayed from `provider.upgrade` capability plus the `always-enabled` policy; these fields must not require opening raw Provider JSON.
