关于使用部分闲置募集资金现金管理进展的公告
Capital/Financing Update Classification · 88% confidence The document is an official company announcement detailing the use of idle proceeds from a prior fundraising (“募集资金”) for cash management products. It describes board authorization, investment amounts, counterparties, risk controls, and progress updates on using the raised funds.

Hence it falls under the Capital/Financing Update category.

关于使用自有资金支付募投项目人员费用并以募集资金等额置换的公告
Capital/Financing Update Classification · 95% confidence The document is an official announcement from a company regarding the use of its own funds to pay personnel expenses for a fundraising investment project and the equivalent replacement with raised funds. It details the background of the fundraising, the use of funds, the reasons for the fund replacement, the operational process, and the approvals by the board and audit committee. It includes references to regulatory approvals and compliance with listing rules. The document is not a full financial report, earnings release, or audit report, but rather a regulatory announcement about the management and use of raised capital. It is a formal disclosure related to capital usage and compliance, fitting best under the category of Capital/Financing Update (CAP). The document length is under 5,000 characters, but it contains substantive details about capital usage rather than just announcing a report publication, so it is not an RPA. Therefore, the classification is CAP with high confidence.

2025年度独立董事述职报告(陈艳)
Board/Management Information Classification · 95% confidence The document is titled as the "2025年度独立董事述职报告（陈艳）" which translates to the "2025 Annual Independent Director's Work Report (Chen Yan)". It is a detailed report by an independent director about her duties, attendance, and activities during the year 2025. The content includes descriptions of board meetings attended, committee participation, communication with shareholders, and oversight activities. It is a formal report on the independent director's performance and responsibilities rather than an announcement or a brief summary. The document length is 3456 characters, which is relatively short but contains substantive content about the director's duties and activities. This type of document fits best under the category of Board/Management Information (MANG), as it relates to the activities and reports of a board member rather than financial results, audit reports, or regulatory filings. It is not an Annual Report (10-K), Audit Report (AR), or any other category. Therefore, the classification is MANG with high confidence.

关于召开2025年年度股东会通知公告（提供网络投票）
AGM Information Classification · 95% confidence The document is a notice announcing the convening of the 2025 Annual General Meeting (AGM) of shareholders for 大连汇隆活塞股份有限公司. It details the meeting date, voting methods (including online voting), agenda items to be discussed and voted on (such as the 2025 annual report, audit report, financial statements, and other corporate matters), registration procedures, and contact information. The document does not contain the actual annual report, audit report, or financial statements themselves, but rather informs shareholders about the meeting where these reports will be reviewed and voted upon. The document length is 3612 characters, which is relatively short and consistent with a meeting notice rather than a full report. Therefore, this document fits the category of AGM Information (AGM-R), which covers presentations and materials shared during the Annual General Meeting, including notices and agendas.
