Summary

Studio administrators can manage MPA collaboration through AgentKit A2A spaces, edit AGENTS.md, and update Runtime and Worker images independently. MPA creation and deletion retain actionable, redacted failure details.

• Add space creation, association, removal and deletion; register existing Runtimes or imported Agent Cards, and view service endpoints and skills.
• Support registered Agent aliases scoped to the current MPA business database through the matching Runtime API. Correct the Agent alias label, remove shared-account setup guidance, and allow the exact alias PUT route while preserving proxy authorization and server-owned credentials.
• Add AGENTS.md load/save/clear with revision conflicts, draft retention, cancellation and administrator-only credential injection.
• Put image updates second in MPA navigation. Runtime and Worker update independently from a full manual address or their domestic/BytePlus public repository; public latest resolves to a version/digest before confirmation and is revalidated on submission.
• Include paired English/Chinese designs and contracts, regression tests and matching packaged WebUI assets. Restore missing Apache license headers in five existing PR Python files.

Validation

Latest revision: f52d46efc07c8d30f87478d295272af785780ea1, synchronized with official main cb9975df on 2026-10-22.

• All-files pre-commit passed, including Ruff and secret scanning. Required license headers are present in all 30 changed PR Python files.
• Default parallel Python regression (-n 2, excluding Codex/Piagent smoke): 7,861 passed, 53 skipped, 4 xfailed, 1 failed. The sole failure is tests/frontend/server/runtime_artifacts/test_writer.py::test_success_uses_trusted_scope_and_hashes_utf8_bytes: local Python 3.10 does not recognize .md MIME. The same test fails in an independent archive of unchanged HEAD 46f60e12; the artifact writer/test were not changed. This local gate remains failing.
• Complete Runtime proxy tests: 142 passed; broader CLI regression: 1,844 passed, 6 skipped.
• Frontend: 1,389 Node + 236 Vitest tests passed; production build, i18n consistency and packaged asset checks passed (114 files / 351 references).
• CI Sidecar backend script: 143 passed / 1 skipped, 9 passed / 50 deselected, 97 passed, 39 passed. Backend coverage 96% exceeds the 91% gate. Frontend Sidecar: 22 passed, 100% line / 94.44% branch coverage.
• Dependency policy and frozen lock validation passed. Pyright on the five license-only files reported zero errors; the existing proxy/test diagnostics were compared with the unchanged baseline and no diagnostics were added.
• Isolated browser checks cover alias save/read-back/clear, CAS conflict and refresh, keyboard cancellation, unsupported Runtime guidance and narrow-container layout; no real cloud/model writes or deployment.

CI status

All seven workflows for this exact revision currently have conclusion action_required, with no jobs started. Attempting approval through the current account returned HTTP 403: Must have admin rights to Repository. These are unexecuted checks, not passing CI results. An official repository maintainer must approve and run the workflows; this PR remains a draft.

Pending Unit Tests run.

Compatibility and limits

The features are scoped to MPA management and require matching agentkit-mpa-agent Runtime APIs; the companion Runtime implementation is outside this PR. Aliases belong to each MPA business database and require no shared management database/account-ID configuration. Previously shared aliases are not automatically imported. Older Runtimes retain explicit unsupported states.

AGENTS.md persistence and Main next-turn updates are verified. Existing native Worker threads are not guaranteed to reload instructions; Worker hot reload remains deferred. Existing sandbox sessions may retain their prior Worker image until a new session is created. This PR does not publish or deploy the companion Runtime.
