Any subset. Out-of-range values are 400 `invalid_request` (ranges in GET `limits`). `null` clears `caps.sandbox_max_cost_micros` or `caps.daily_cap_micros` (no cap). `reset: true` starts from the defaults. Audited as `proxy.settings.update` with old and new values. ## OpenAPI ````yaml /api-reference/openapi.yaml patch /v1/proxying/settings openapi: 3.1.0 info: title: Zode API version: 0.1.0 description: Sandboxes for coding agents.
