Add trusted provider flag for strict mode response sanitization by pjb157 · Pull Request #724 · doublewordai/control-layer

pjb157 · 2026-02-17T20:44:42Z

Summary

Adds support for marking model providers as trusted when strict mode is enabled. Trusted providers bypass error response sanitization, while non-trusted providers have sensitive error details removed.

Changes

Add trusted boolean column to deployed_models table (migration 066, defaults to false)
Expose trusted field in model creation and update APIs
Integrate trusted flag with onwards strict mode sanitization logic
Add comprehensive test coverage for strict mode behavior

API Usage

Create a trusted provider:

POST /admin/api/v1/models
{
  "model_name": "gpt-4",
  "trusted": true
}

Update existing provider:

PATCH /admin/api/v1/models/{id}
{
  "trusted": true
}

Testing

All 867 tests passing
Clippy clean

Notes

Backend implementation is complete and production-ready. Frontend UI support will follow in a separate PR.

- Add `trusted` boolean column to deployed_models table (migration 066) - Expose trusted field in model CRUD APIs (defaults to false) - Integrate with onwards strict mode sanitization logic - Trusted providers bypass error sanitization in strict mode - Non-trusted providers have errors sanitized (removes sensitive details) - Add comprehensive tests for strict mode behavior - All 867 tests passing, clippy clean Backend implementation complete. Frontend UI support to follow in separate PR.

Pull request overview

Adds a per-deployed-model trusted flag to control strict-mode error sanitization behavior when proxying through Onwards, and wires it through DB, admin APIs, and the Onwards config sync pipeline.

Changes:

Add trusted column to deployed_models (migration 066) and plumb it through DB create/update/read paths.
Extend admin model create/update/response schemas to include trusted (and expose strict-mode via /config).
Update Onwards config generation to emit trusted, bump onwards crate, and add strict-mode integration tests.

+with_replacement: composite.fallback_with_replacement,


Line indentation for the with_replacement field is inconsistent with the surrounding struct literal and looks like rustfmt hasn’t been applied. This will likely cause cargo fmt --check to fail; re-run rustfmt on this file before merging.

DeploymentCreateDBRequest::sanitize_responses is documented/built as defaulting to true, but the deployed_models.sanitize_responses column default is FALSE (see migration 056) and from_api_create defaults to false. To avoid surprising behavior for any other callers of the builder, align the builder default and doc comment with the DB/API default (i.e., default to false).

The repo’s SQLx offline cache appears out of sync with these query changes: searching .sqlx/ shows no metadata containing the new trusted column. If CI/lint runs cargo sqlx prepare --check --workspace (or developers build with SQLX_OFFLINE=true), this will fail. Regenerate and commit the updated .sqlx query metadata after adding trusted.

+        }


This test currently continues when endpoint creation doesn’t return 201, which can silently skip coverage and let the test pass without asserting the behavior. Prefer asserting success (or using unique names/cleanup) so failures are surfaced rather than skipped.

Suggested change

// Handle potential conflicts from auto-sync

if endpoint_response.status_code() != 201 {

eprintln!("{}: Endpoint creation returned {}, skipping test case",

description, endpoint_response.status_code());

continue;

}

// Endpoint creation is a required precondition for this test case; assert success

The model-availability polling loop has a hard 1s timeout with fixed 10ms sleeps; this can be flaky on slower CI or under load (sync may legitimately take longer). Consider using the existing attempt-based polling pattern used elsewhere in tests (or increasing the timeout/backoff) to make this test reliable.

- Add `trusted` field to TypeScript Model types - Add `onwards.strict_mode` to ConfigResponse type - Update ModelInfo to conditionally show: - `trusted` checkbox for standard models when strict mode is enabled - `sanitize_responses` checkbox for virtual models (always shown) - Trusted providers bypass error sanitization in strict mode - UI only appears when relevant (strict mode on for standard models) Completes frontend support for trusted provider flag feature.
