问题

在 attachForwardMsgIdToContext 开启时，adapter-onebot（NapCat / LLBot）下的合并转发消息只会被注入为无参数的 <forward/>，丢失了转发记录 ID，导致 read_forward_msg 一类下游工具拿不到 messageId 入参。

原因

OneBot v11 的合并转发 CQ 码规范为 [CQ:forward,id=...]（Array 格式对应 {"type":"forward","data":{"id":"..."}}），adapter-onebot 会把 data 浅拷贝到元素属性上，因此元素是 h('forward', { id: '...' })。而 pickForwardMessageId 目前只检查 message_id / messageId，对 forward 元素返回 null。

修改

packages/core/src/utils/koishi.ts 中的 pickForwardMessageId：

• type === 'forward' 的元素优先读取 id（转发记录唯一索引 / resId），再回退到 message_id、messageId；
• 其它 message 元素保持原有 message_id / messageId 的读取逻辑不变，避免出现“元素自身 ID 与转发 ID 冲突”的顾虑。

const candidateKeys =
    element.type === 'forward'
        ? ['id', 'message_id', 'messageId']
        : ['message_id', 'messageId']

for (const key of candidateKeys) {
    const normalizedId = normalizeForwardMessageId(attrs[key])
    if (normalizedId) return normalizedId
}

return null

验证

• 以 h('forward', { id: '7699285893324238179' }) 为例，现返回 "7699285893324238179"。
• 覆盖用例：数字型 ID、首尾空白、空字符串回退到 message_id、forward 元素仅有 message_id / messageId、无属性返回 null、以及带 forward=true 的 message 元素不会被误读 id。
• 本地运行时（1.4.3 + 上述补丁）实测：模型上下文注入 <forward id="1853201431"/>，模型可正常调用 read_forward_msg({"messageId":"1853201431"})。

Walkthrough

消息转换器调整前置转换、引用内容合并和元素递归处理。中间件移除转发历史状态，并在处理转发元素时更新消息内容及转发 ID。渲染器调整附加回复的转发消息构造方式。

Changes

转发消息处理

Layer / File(s)	Summary
消息转换与引用内容合并 packages/core/src/services/message_transform.ts	转换器依序执行前置转换，并递归处理元素子节点。引用转换结果中的转发 ID 会合并到当前消息并去重；引用内容按字符串或非字符串路径组合。
转发元素捕获与上下文更新 packages/core/src/middlewares/chat/read_chat_message.ts, packages/core/src/utils/koishi.ts	中间件处理 forward 元素和 forward 属性为 "true" 或 "1" 的 message 元素。符合条件时，addForward 追加转发标记并记录尚未出现的 ID。中间件不再保存转发历史状态，三个转发辅助函数已移除。
附加回复渲染 packages/core/src/render/index.ts	render 调用 renderAdditionalMessages，并将其返回的元素包装为渲染消息。附加回复的原始渲染结果直接作为转发消息的子元素。

Merge Risk: 🟡 Moderate · up to 89a7b

Forward messages using the previously supported alternate ID attributes can lose their record ID in chat context. Restore that lookup before merging unless the narrower behavior is intentional.

Pre-merge checks: 3 · 2

Failed checks: 2 warnings

Check name	Status	Explanation	Resolution
Title check		标题声称修改 pickForwardMessageId 以支持 forward.id，但变更实际删除了该函数，并重构了转发消息处理流程。因此标题与实际变更不一致。	将标题改为描述实际变更的内容，例如“refactor(core): 重构转发消息处理与 ID 注入逻辑”。
Docstring Coverage		Docstring coverage is 16.67% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 6 functions across 4 files.	Write docstrings for the functions missing them to satisfy the coverage threshold.

Passed checks: 3 passed

Check name	Status	Explanation
Description check		描述围绕 OneBot 合并转发消息的 ID 丢失问题展开，与变更涉及的转发消息处理和 ID 注入逻辑相关。尽管描述中的具体实现与当前差异不完全一致，但满足宽松的相关性要求。
