Make Noema a first-class decision agent inside naruon. Judgments call only the orchestrator gateway (dedicated Fernet-KV token, HTTPS /v1 URL, single model alias contextual-orchestrator) with no sequential model failover and no upstream provider keys at request time.

Keep resolve_runtime_llm_provider for search/chat/embeddings and assert Noema no longer imports that tenant provider path. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>
Remove the Decision Points API and judgment.decide mapping so this change only swaps Noema's LLM client to contextual-orchestrator. Catalog mappings and the existing tool surface stay; no tenant gpt-4o picker. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>

Reviewed head 15ec8c80c026877c512641cfb702f691f1caa43d (cursor/noema-orchestrator-decision-agent-816f → develop) against the first-slice contract and the listed repo rules. Files read on disk at that SHA.
Suggested review event: REQUEST_CHANGES — one fail-closed hole on the new LLM client path. Routing contract (no tenant model pick, no sequential failover, no dispatcher) is otherwise honored. Posted as COMMENT because this automation must not self-approve and some cursor-authored PRs reject REQUEST_CHANGES/APPROVE.

1. Blocking findings
P1 — build_noema_agent does not fail closed the way batch embedding already does
- path:line:
backend/services/noema_agent.py:494andbackend/services/noema_agent.py:589 - Evidence: nearby implementation in
backend/services/batch_embedding_service.py:250-266(_run_orchestrator_batchcatchesValueError, closes the client, and returnsNonewhennormalized_url is None). This PR copies the old tenant-provider client construction instead. - Impact:
build_llm_provider_http_clientraisesValueErroron allowlist miss, non-global DNS, or the 5s async DNS timeout.run_noema_agentonly wrapsagent.run(616-625), so a flake after a successfulresolve_orchestrator_gatewayescapes with noerror_codeand violates the module contract that the agent “returns a structured no-op notice instead of raising.” If the helper returns(None, client)— empty/rejected URL —AsyncOpenAI(base_url=None)(497-501) sends the dedicated Fernet-KV inference token to the public OpenAI default host. That is a tenant-model / upstream-key leak the slice exists to prevent. - Smallest fix: Copy the batch-embedding guard. After
build_llm_provider_http_client, ifvalidated_base_urlis missing,await http_client.aclose()and fail closed. CatchValueErroraround the helper. Inrun_noema_agent, treat that failure asstatus="unavailable"+error_code="orchestrator_gateway_unavailable"(do not map it tonoema_runtime_unavailable). Do not constructAsyncOpenAIuntil the URL is a non-empty HTTPS/v1string. - Verification:
cd backend
PYTHONWARNINGS=error python3 -m pytest tests/test_noema_agent.py tests/test_orchestrator_gateway.py -qAdd a test that build_llm_provider_http_client raising ValueError or returning (None, client) yields error_code=="orchestrator_gateway_unavailable" and never instantiates AsyncOpenAI with base_url is None.
- Cursor can apply safely: yes — local, ~15 lines, no new API surface.
No other blocking rule failures on this head: no resolve_runtime_llm_provider / gpt-4o / model_profile_id in noema_agent.py; no COPILOT_GITHUB_TOKEN / GitHub Models path; no sequential model_candidates; token is EncryptedString (backend/db/models.py:1371); Alembic 0018 uses op.add_column / op.drop_column (no sa.text(f"...")); no new /api/* router (HMAC admin / get_auth_context N/A); tests do not contain Timeout/Fatal/Warn/Denied.
2. Non-blocking notes
- P2
backend/services/orchestrator_gateway.py:123—resolve_orchestrator_gatewaycalls syncvalidate_llm_provider_base_url(unboundedsocket.getaddrinfo). The async helper used at build time has a 5s cap. Prefervalidate_llm_provider_base_url_asyncso a slow DNS cannot hang the event loop when a route is added. - P2
backend/tests/test_noema_agent.py:351— runtime-missing path does not asserterror_code=="noema_runtime_unavailable". - P3
backend/requirements-agent.txt:16-18— comment still says openai2.44.0/ pydantic-ai2.8.0; lock isopenai==2.45.0and the pin ispydantic-ai-slim[openai]==2.9.0. - P3
backend/services/noema_agent.py:617—logger.info("... %s", exc)can echo provider exception text. Keep the generic notice; logtype(exc).__name__only. - P3
tool_search_mail/tool_read_mailstill return sequentialemail.id(181,211). Pre-existing #970 surface; do not expand in this slice. - CodeRabbit CLI
0.7.3is installed here butauth status --agentisnot_authenticated. This review is from the checked-out files, not a CodeRabbit check-run.
3. First-slice contract — honored (except the fail-closed hole above)
| Rule | Result |
|---|---|
No resolve_runtime_llm_provider / tenant gpt-4o / model_profile_id |
Honored. Source guard at backend/tests/test_noema_agent.py:508-525. |
Single alias contextual-orchestrator |
Honored. ORCHESTRATOR_MODEL_ALIAS + model_candidates=() (orchestrator_gateway.py:28, 134-138; noema_agent.py:506-508). |
| No sequential failover | Honored. Catalog sequential_failover: false. No candidate loop. |
| No COPILOT / GitHub Models | Honored. FORBIDDEN_GATEWAY_HOSTS + denylist (orchestrator_gateway.py:32-48, 87-88). |
| Upstream keys stay in orchestrator KV | Honored. Dedicated noema_orchestrator_token only. |
HTTPS + ALLOWED_LLM_BASE_URL_HOSTS + build_llm_provider_http_client |
Intended; hole is the missing fail-closed wrapper, not a second picker. |
Catalog-only; no Decision Points / mail.triage dispatcher |
Honored. No POST /api/noema/*, no run_noema_decision, no judgment.decide. resolve_agent_for_task is test/catalog only. |
| EncryptedString + structured Alembic | Honored. SQLite raw-SQL test proves Fernet at rest (test_orchestrator_gateway.py:139-142). |
4. Buyer-facing gaps — NEXT PR, not this slice
- Settings / signed-session write path for
noema_orchestrator_base_urlandnoema_orchestrator_token(mask presence, blank-preserves-stored, no public identity headers)./api/configdoes not mention these fields today — operators cannot turn Noema on from the product. - Honest AI Hub / Today surface that calls
run_noema_agentover the cookie proxy and rendersorchestrator_gateway_unavailableinstead of a silent no-op. - Decision Points /
mail.triagedispatcher only after (1)+(2) and the fail-closed fix. Do not inventjudgment.decidehere. - Allowlist onboarding: operator must add the gateway host to
ALLOWED_LLM_BASE_URL_HOSTSor every run fails closed. - Tool honesty: stop returning sequential
email.id; writeback should take opaquesource_uid, not a free-formaccountstring.
5. Suggested event
REQUEST_CHANGES — the routing slice is the right shape, but run_noema_agent is not fail-closed on the pinned HTTP client the way batch_embedding_service already is. That is in-scope for this consumer-path PR. After the guard + one regression test, this slice is approvable without adding a dispatcher.

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -

Description
First bounded Noema integration slice:
run_noema_agentno longer resolves a tenant OpenAI-compatible model/provider and sends all LLM completions through one dedicated contextual-orchestrator gateway contract.run_noema_agentstill has no production dispatcher. The registered agent/task catalog remains catalog-only. This PR does not add a Decision Points API,mail.triagedispatcher, orjudgment.decidecapability.Implemented contract
noema_orchestrator_tokenand HTTPS/v1gateway URL;contextual-orchestrator;AsyncOpenAIconstruction, preventing fallback to the public OpenAI default host;Review-driven RED → GREEN
The review identified a concrete fail-closed hole:
build_llm_provider_http_client()could raise before the existing agent-run exception boundary, while a(None, client)result could reachAsyncOpenAI(base_url=None).A test-only regression first reproduced both cases:
ValueErrormust map tostatus=unavailableanderror_code=orchestrator_gateway_unavailable;AsyncOpenAI.Production now enforces those contracts with the narrow gateway-client guard and a stable public outcome.
Scope exclusions
POST /api/noema/decisions;run_noema_decisionwrapper;Verification boundary
Focused Noema/gateway regressions, Ruff, Python 3.14, full exact-head repository checks, security/coverage/dependency/container evidence, zero actionable threads, and qualifying independent non-author approval remain mandatory. Pending, cancelled, stale, predecessor-head, status-only, model-only, or author-only evidence is non-passing.
