招商证券股份有限公司关于深圳天溯计量检测股份有限公司2025年度持续督导跟踪报告
Regulatory Filings Classification · 45% confidence The document is a continuous supervisory tracking report (“持续督导跟踪报告”) prepared by the sponsor (招商证券) for Shenzhen TianSu Measurement & Testing Co. It details the sponsor’s review of disclosures, governance, fund supervision, issues found, and follow-up measures. This is neither an earnings or annual report, nor a dividend, proxy, M&A, board change, or other specialized filing. It is a regulatory compliance report required by the exchange but does not match any more specific category, so the appropriate classification is the general Regulatory Filings category (RNS).

独立董事2025年度述职报告(贺存勖)
Board/Management Information Classification · 95% confidence The document is titled as an "Independent Director 2025 Annual Work Report" for Shenzhen Tiansu Measurement Testing Co., Ltd. It details the independent director's background, attendance at board and committee meetings, communication with auditors, and overall evaluation of the company's governance and audit processes during the 2025 fiscal year. The content focuses on the independent director's duties, oversight, and compliance with laws and regulations, rather than presenting financial statements or audit results themselves. It is a formal report by an independent director summarizing their annual duties and observations, which fits the category of Board/Management Information (MANG) as it relates to governance and management oversight rather than a full annual report, audit report, or other financial filings. The document length (4606 characters) and detailed narrative support this classification with high confidence.

2026年一季度报告
Interim / Quarterly Report Classification · 100% confidence The document is titled as the "2026年第一季度报告" which translates to "2026 First Quarter Report". It contains detailed financial data including income statement, balance sheet, cash flow statement, and explanations of financial changes for the first quarter of 2026. The document explicitly states it is a quarterly report and includes comprehensive financial statements and analysis for a period shorter than a full fiscal year. It also mentions that the report is unaudited, which is typical for interim or quarterly reports. There is no indication that this is an announcement of a report or a certification document. Therefore, the document fits the definition of an Interim / Quarterly Report (IR).

董事会审计委员会对会计师事务所2025年度履职情况评估及履行监督职责情况的报告
Audit Report / Information Classification · 95% confidence The document is a detailed report from the Board Audit Committee evaluating the performance and supervision of the external audit firm for the fiscal year 2025. It discusses the audit firm's qualifications, the audit process, meetings held, and the audit committee's oversight activities. The document does not contain the actual audited financial statements or the audit report itself but rather an evaluation and supervisory report on the audit firm's work and performance. This fits the definition of an Audit Report / Information (AR) filing, which includes standalone audit reports and results of internal or regulatory oversight related to audits, excluding full annual reports. The document length is 2600 characters, which is relatively short but contains substantive content about audit oversight rather than just an announcement or certification. Therefore, the appropriate classification is AR with high confidence.
