feat(jev): add native /v1/systemone endpoint by SantiagoDePolonia · Pull Request #1097 · ENTERPILOT/GoModel

SantiagoDePolonia · 2026-09-26T16:56:38Z

Adds POST /v1/systemone, a native endpoint for TypeSafe's System One decision API: Jev, self-hosted Kev servers, and OpenRouter, which serves Jev natively.

User-visible impact

Available only when a jev or openrouter provider is configured, otherwise 404. Checked per request, so providers added at runtime enable it without a restart.
Native, never translated: the body is forwarded as sent; only model (resolved name) and state (if a guardrail edited it) change. The answer is relayed unchanged.
Gateway features apply: virtual models, model allowlists, rate limits, budgets, workflow policy, audit log (new System One request type in the dashboard filter), and usage (tokens recorded under the answering model; OpenRouter's usage.cost kept).
Guardrails see state as a single user message. Edits System One cannot carry (e.g. an injected system prompt) are dropped with a warning log; a guardrail that would answer the request blocks it instead.
Misuse is explicit: a model on a provider without System One, or one the catalog lists with a generation mode (e.g. an OpenRouter chat model), returns 400 explaining the endpoint does not translate, and logs a warning. Jev models on chat, /responses, and embeddings now point to /v1/systemone.

Provider-specific behavior

Targets: jev providers and OpenRouter, which serves Jev natively at /api/v1/systemone. An OpenRouter key alone enables the endpoint.
OpenRouter's model listing previously dropped decisions-output models; they are now kept as utility models (no chat mode), priced from the listing: typesafe/jev-1.13, ~typesafe/jev-latest, Kev 4B, and others. One virtual model can front a local Kev and OpenRouter's Jev.
Kev stays on the jev type: same wire API; name it kev in config.yaml to see that name in logs and usage.
Not included yet: response caching, failover, and native permute/separate (still reachable via /p/jev/...).

Docs: docs/providers/jev.mdx (new "The native endpoint" section; also fixes the page icon, a Font Awesome name the Lucide icon set did not render), provider overview, config example, and the regenerated OpenAPI reference.

Summary by CodeRabbit

New Features
- Added native POST /v1/systemone support when a Jev or OpenRouter provider is configured, with bearer authentication and provider-native responses.
- System One requests support model selection, request-state guardrails, access controls, usage tracking, and audit logging. Requests for models without System One support are rejected rather than translated.
- OpenRouter decision models appear in the model catalog as utility models.
- Added “System One” as an audit-log request type across supported dashboard languages.
Documentation
- Updated API, provider, and configuration guidance for native System One requests and passthrough routes.

📝 Walkthrough

Walkthrough

GoModel adds POST /v1/systemone for native System One requests. The route resolves and authorizes models, applies state guardrails, and forwards supported requests to Jev or OpenRouter. It records audit and usage data, and the dashboard identifies System One audit entries.

Changes

Native System One

Layer / File(s)	Summary
Endpoint and request contract `internal/core/endpoints.go`, `internal/core/endpoint_operations.go`, `internal/core/systemone.go`, `internal/core/workflow.go`, `internal/core/endpoints_test.go`	The endpoint is classified as a JSON System One operation. Its workflow enables alias resolution, guardrails, and usage tracking.
State guardrail processing `internal/gateway/interfaces.go`, `internal/plugins/exchange/systemone_request.go`, `internal/plugins/exchange/systemone_request_test.go`, `internal/guardrails/workflow_executor.go`, `internal/guardrails/integration_test.go`	System One state is exposed to the prompt chain as one user message. Supported edits are applied to a copy of the request. Edits that cannot be carried are logged.
Provider model discovery and lookup `internal/providers/openrouter/openrouter.go`, `internal/providers/openrouter/openrouter_test.go`, `internal/providers/router_models.go`, `internal/providers/registry_normalization_test.go`	OpenRouter discovery retains decision-modality models as utility models. The router adds model lookup for qualified and bare selectors and returns a copy of matching catalog data.
Request resolution and provider forwarding `internal/server/http.go`, `internal/server/systemone_handler.go`, `internal/server/model_validation.go`, `internal/server/messages_native.go`, `internal/server/systemone_handler_test.go`, `internal/providers/jev/jev.go`, `internal/providers/jev/jev_test.go`	The route checks provider availability, resolves and authorizes the model, applies state guardrails, and forwards supported requests to Jev or OpenRouter. Other provider types and catalogued models with generation modes are rejected. Successful responses are proxied with audit, usage, and pricing handling.
API documentation and audit display `cmd/gomodel/docs/docs.go`, `docs/openapi.json`, `docs/providers/jev.mdx`, `docs/providers/overview.mdx`, `config/config.example.yaml`, `web/dashboard/src/pages/audit-logs/audit-operations.js`, `web/dashboard/messages/*.json`, `web/dashboard/tests/audit-operations.test.js`	The API and provider documentation describe native endpoint behavior, constraints, and setup. The dashboard maps the exact route to the System One audit type and adds translations.

Merge Risk: 🟡 Moderate · up to 3eddb

Native System One requests through OpenRouter may fail at the upstream endpoint. Confirm or correct the forwarding URL before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 3eddb

Some protective request changes cannot be applied to the new endpoint, yet the request can still proceed. Existing access restrictions limit exposure, but this behavior warrants review.

Retained concerns

Medium · security · inferred: If a configured policy relies on an inserted instruction or parameter change to protect a request, the native endpoint logs and drops that change but can still forward the request. State edits and explicit guardrail blocks do take effect, so the exposure is conditional on the policy.

Security review details

Security Blast Radius

inferred — A caller able to use the new route can send native state to an authorized, configured Jev or OpenRouter provider. The inspected path does not establish access to an unauthorized provider or model.

Security Findings and Attack Paths

inferred — A policy that protects provider requests by inserting an instruction or changing a parameter may appear to run, while that protective edit is dropped and the native request continues. No affected production policy was identified.

Trust Boundaries and Controls

observed — The resolved model is checked for access before dispatch. Explicit guardrail short circuits block the request, and supported state edits are written into the forwarded body.

Hardening Proposals

proposed — Where a configured policy requires edits that the native contract cannot carry, reject the request or constrain that policy to enforceable state edits rather than relying on a warning.

Confidence Score: 5/5

[High risk] Adds a new public API endpoint for decision requests.

The PR appears safe to merge. No new actionable issue was found.

What we checked:

In-place state edits still apply: No. The handler saves the old state before the guardrail runs, so an in-place edit is detected and sent upstream.
Unavailable routes return 404 first: No. Workflow setup now skips model resolution when no System One provider is configured, so the handler returns the promised 404.
