+### 2026-09-19 — preserve the system role for DashScope
+
+- Reason: DashScope endpoints were treated as supporting the `developer` role, causing thinking-enabled OpenAI-compatible conversations to send an unsupported system-prompt role.
+- Affected package: `packages/ai` (`@earendil-works/pi-ai`), OpenAI Completions compatibility detection.
+- Change: default to the `system` role for official DashScope regional and Coding Plan hosts, plus workspace, trial, and Token Plan hosts under the documented regional `maas.aliyuncs.com` domains. Preserve thinking, other request options, explicit compatibility overrides, and other providers.
+- References: [official endpoint list](https://help.aliyun.com/en/model-studio/base-url), [Coding Plan role rejection](https://github.com/openclaw/openclaw/issues/23575), [Token Plan role rejection](https://github.com/earendil-works/pi/issues/7723), and [merged OpenClaw DashScope fix](https://github.com/openclaw/openclaw/pull/24675).
+- Upstream PR: not opened.
+- Validation: request-payload regressions in `packages/local-runtime-v2/src/service/model-system/resolution/local-model-resolver.test.ts`, including official endpoints, unrelated hosts, and explicit compatibility overrides.
