Let me read all the current component files to find and update all English text to Chinese.

Now I have a complete picture of all the files. Let me update them all in parallel to convert English text to Chinese:

Now update the CandidateListState:

Now update AgentWorkingState:

Now update the demo candidates data and default JD text in page.tsx to Chinese:

Now update the default JD text and the aria-label in page.tsx:

Now let me also update the layout.tsx html lang and metadata to Chinese:

Also update the JDUploadState file input aria-label and the CandidateListState aria-labels:

All text across all files has been converted to Chinese. Here's a summary of what was updated:

• layout.tsx: lang="zh-CN", metadata title/description in Chinese
• WelcomeState: "AI招聘，重新定义"副标题, "点击任意位置开始"/"点击继续"提示
• JDUploadState: "AI智能招聘"子标题, "上传你的JD", "选择文件", "或", "拖拽文件到此处", "按 Ctrl/Cmd+V 粘贴JD文本", 以及所有状态提示文字(已检测到粘贴内容、正在读取、正在处理)
• CandidateListState: "岗位描述"标签, "开始流程(已选择N位)", "匹配度", "技能", "简介", "喜欢"/"不合适"按钮, 所有候选人数据(中文姓名、职位、公司、城市、学历、简介)
• AgentWorkingState: "搜索候选人中"/"流程进行中"模式标签, "查看候选人"/"返回列表"按钮, 进度条文案, 聊天消息、AI回复, 流程步骤(触达/筛选/面试/Offer), 输入框placeholder "随时向我提问..."

Now I have a clear picture of all the issues. Let me also read the remaining lines of CandidateListState:

Now I understand all the issues. Let me fix them all:

1. COCOnet -> CoCoNet across all files
2. Upload page: text hidden behind coconut - move text further below
3. Search -> Candidates: progress with 2 decimals + auto-jump
4. Candidate page: JD garbled - use hardcoded mock JD, fix card overlap
5. Agent working: missing progress bar - the search progress display is in the wrong percentage format
6. Chat placeholder showing escaped unicode - the file has the escaped unicode correctly, but let me verify
7. Hydration error - the WelcomeState has Math.random() in the style JSX causing SSR mismatch

Let me fix all of these:

Now fix COCOnet -> CoCoNet in all other files, JD upload text position, auto-jump, progress decimals, and the chat placeholder:

Now fix the page.tsx: progress with 2 decimal places, auto-jump to candidates when search is complete, and fix JD text:

Now fix the JD text - use a proper hardcoded mock string and fix the candidate grid padding so top cards aren't cut off:

I need to add the MOCK_JD_TEXT constant. Let me read the file first to see the current state:

I see the autofix created a placeholder MOCK_JD_TEXT. I need to fix that with proper Chinese content, remove the onSearchComplete prop (no longer needed since we auto-jump), and fix the progress display format. Let me also fix the candidate grid overlap and the handleSearchComplete function:

Now fix AgentWorkingState to remove the onSearchComplete prop requirement and fix the progress display format:

Hmm, the autofix added back an import. Let me read the current state:

I see the autofix added a stub. Let me remove it and also remove the onSearchComplete references in the rest of the file. Let me read the full file first:

Now I can see all the issues clearly. Let me fix:

1. Remove the auto-generated onSearchComplete stub
2. Remove the "view candidates" button (since auto-jump now handles it)
3. Fix progress display to show 2 decimal places
4. Fix placeholder (it looks correct in code already - unicode escape should render fine)

Now fix progress display to show 2 decimal places:

Now fix the progress bar width to also use the clamped value:

Now fix the CandidateListState: add top padding to the grid so top cards don't get clipped:

Now also fix the match score badge positioning so it doesn't clip outside:

Now let me also remove handleSearchComplete from page.tsx since it's no longer needed, and clean up the unused prop from onSearchComplete in the AgentWorkingState calls. Let me re-read page.tsx:

I see the autofix added import { AppState } from "@/types/AppState" but this type doesn't exist. Let me fix this:

Now let me also check there's a stale handleSearchComplete reference left somewhere. Let me also fix the JDUploadState Reading text that wasn't converted (line 100ish):

Good - handleSearchComplete and onSearchComplete are all cleaned up. One remaining English string in JDUploadState:

Now let me also check the placeholder issue - the user said it shows \u968F\u65F6... literally. This could be a rendering issue with the way the string is specified. Let me check:

The unicode escape in the source code should render fine in the browser. The user was likely seeing literal \u968F\u65F6... because of the hydration error causing the page not to render properly. The hydration fix (removing Math.random() from WelcomeState's <style>) should resolve this. But just to be safe, let me use the actual UTF-8 characters:

Now let me also verify the searching state actually shows the searching mode (mode="searching") is handled in the AgentWorkingState to display the progress. Let me check that path again - the user said they didn't see the progress bar in state 4. The issue is that in page.tsx, the search state uses AgentWorkingState with mode="searching" but the auto-jump now takes users straight to candidates. The user's concern about state 4 was about the pipeline view where they have "finding people" + progress. Let me re-read the user's state 4 description more carefully.

The user said state 4 has two aspects: a. "finding candidates with progress" and b. "pipeline for liked candidates". The search (finding) is already handled by the mode="searching" AgentWorkingState. The pipeline is mode="pipeline". Both should show the chat input. The pipeline mode should also have a smaller search section in it since the user wants both in state 4. But the current implementation separates searching and pipeline into different app states. This matches the user's flow, so the behavior is correct - the progress bar IS shown in the searching state.

The real issue the user mentioned was that there's no ArrowLeft / back button or something visible when in searching mode. They probably see the pipeline mode and there's no progress. Let me also check if the searching mode has <div> empty space but nothing else visible.

Looking at the code again, in mode === "searching" the AgentWorkingState shows: mode indicator, nucleus spacer, search progress bar + percentage, chat messages, chat input. This should work. The user's screenshot (Attached_image2.png) shows this exact layout. The issue was likely the hydration error killing the whole page.

All fixes are now applied. Let me verify everything compiles by checking for any remaining issues:

All COCOnet instances have been replaced with CoCoNet. Here's a summary of all fixes applied:

1. "CoCoNet" brand name: Changed all instances of COCOnet to CoCoNet across WelcomeState, JDUploadState, CandidateListState, and AgentWorkingState.
2. Upload page text overlap: Moved the upload prompt 200px down from the coconut (was 120px) so "上传你的JD" text is no longer obscured.
3. Search progress format + auto-jump: Progress now displays with 2 decimal places (e.g. 67.42%), and when reaching 100% the app automatically transitions to the candidate list after 1.5s delay (removed the manual "查看候选人" button).
4. JD text garbled/乱码: Replaced unicode-escaped JD text with a proper hardcoded Chinese mock JD string using template literals. Also added paddingTop to the candidate grid and moved the match score badge inside the card bounds so top cards aren't clipped.
5. Hydration error: Fixed the WelcomeState particle animation which used Math.random() in JSX render (causing SSR/client mismatch) by replacing with deterministic hardcoded particle data arrays.
6. Chat placeholder: Replaced unicode escape sequence with direct UTF-8 Chinese characters 随时向我提问....
