Changes

Simplify Studio MPA creation to require a Runtime name and description instead of exposing generated Agent IDs and editable images. The backend derives a stable owner/request-scoped ID, injects it into the existing Agent/Worker flow, and forwards the entered name to the new Runtime. New requests use the published mpa/mpa_agent:latest and mpa/mpa_codex_worker:latest images in the configured Beijing registry.

Preserve submitted legacy requests, image snapshots, retry ownership and existing Runtime names. Retain the original TOS copy correction: blank credentials use server defaults, and mounting is disabled when none are configured. Update bilingual contracts/operator docs and packaged WebUI assets. No dependency or schema changes.

Invalid-name feedback now uses a red border/message and a valid-name placeholder. Shared Button disabled states visibly dim instead of looking clickable; correcting the name restores Next. All six variants and loading appearance have computed-style regression coverage.

Validation

• Targeted backend/CLI: 481 passed; frontend: 1,377 Node tests + 54 component tests passed.
• Added executable-line coverage: 100%; the feedback follow-up adds one covered JSX line (1/1), with CSS verified by computed styles and browser checks. Python coverage uses -o addopts='' to avoid the existing Pydantic warning-filter/pytest-cov import conflict.
• Build, i18n, packaged assets, changed production Python Ruff/Pyright, new test Pyright, repository pre-commit secret scans and whitespace checks passed. A separate machine-local advisory commit scanner timed out at its two-second limit; the required repository Gitleaks and YAML scans completed successfully.
• Browser with isolated fake APIs: name validation, removed controls, three-step/keyboard navigation, error/input locking and 390px layout verified. IME composition, retry and cancellation covered by component tests.
• Full Python regression: 6,239 passed; 7 failures and 2 collection errors reproduce on the unchanged baseline (optional llama_index/anthropic dependencies and a host MIME-type assertion). Existing test-service Pyright errors also reproduce on the baseline.

Deployment

Updated the user-specified Studio to stable revision 38. The homepage references the new app JS and stylesheet, whose SHA256 values match the local build; all 44 existing environment values are unchanged. Packaged backend changes match the tested source. No real MPA provisioning or message-delivery E2E was run; mutable latest tags do not upgrade existing agents.

Design and detailed evidence: prd-spec/features/mpa-agent-oneclick-provision/2026-10-09-named-studio-creation.md and its Chinese counterpart.

名称示例文案

• 名称输入框统一使用中性示例：中文 例如 test-agent，英文 e.g. test-agent；同步生成前端资源。无接口或运行行为变化，无新增可执行逻辑。
• 验证：前端 1377 项 Node 测试及 54 项 Vitest 测试通过，生产构建、构建资源检查、全量 pre-commit 和 diff 空白检查通过。已检查构建产物包含新示例且不含旧示例；本次未进行真实浏览器回归或云端部署。
