-`dsh-llm` defines `SystemPromptUpdate = 'in-history'` and carries it as an optional sibling field, `systemPromptUpdate`, on `LlmResolvedModelInfo` and `PreparedLlmCall`; `normalizeModelInfo` rejects any other value with an `LlmError` whose code is `INVALID_MODEL_INFO`. The DeepSeek adapter's catalog model (`DeepSeekCatalogModel.systemPromptUpdate`, validated by zod at load) and the replay provider's `ReplayModelConfig.systemPromptUpdate` declare it per model; absence means the model needs message 0 rewritten. No default catalog entry declares it; a deployment enables it through the `models` list in `cordis.yml`, and every `dsh-llm-pi-ai` route keeps the replace behaviour.

The DeepSeek adapter's catalog model (`DeepSeekCatalogModel.systemPromptUpdate`, validated by zod at load) and the replay provider's `ReplayModelConfig.systemPromptUpdate` declare it per model; absence means the model needs message 0 rewritten. The sole built-in entry in `dsh-llm-deepseek`, `deepseek-flash`, declares it alongside text and image input. This exact catalog entry records the model capability; names and protocol families do not imply support for other models. A deployment can replace the catalog through the `models` list in `cordis.yml`, and every `dsh-llm-pi-ai` route keeps the replace behaviour.
 
 The loop records the mode in the session: `RequestContext.systemPromptUpdate` joins provider, model, and capacity as a `request/context` field, logged whenever any of them differs from the latest snapshot. Admission reads `PreparedLlmCall.systemPromptUpdate` from the actual call prepared after `agent/request`; the preceding snapshot is not an admission input. First requests, resumed sessions, route changes, and same-route capability changes therefore use the capability of the bound adapter that will serve the call.

 循环把该模式记录进会话：`RequestContext.systemPromptUpdate` 与 provider、model、容量并列成为 `request/context` 的字段，其中任一项与最新快照不同时就记录一次。准入读取 `agent/request` 之后实际准备调用的 `PreparedLlmCall.systemPromptUpdate`；先前快照不是准入输入。因此首次请求、恢复的会话、路由变更以及同一路由的能力变更，都使用将服务该调用的绑定适配器的能力。
