The packet is the first analytical control资料包本身就是第一道分析控制
Build a controlled packet rather than dropping an inbox into a tool. Keep source copies; select regulator or issuer originals; include all primary statements, policies, and relevant notes; label issuer, form, filing date, period, currency, unit, audit status, and amendment scope; and record exclusions. Retain scans and log OCR corrections separately. Remove unnecessary sensitive material and confirm authority to upload. Ask one bounded question, then sample-check identity, locators, signs, units, columns, and totals against the source. Do not invent undocumented format, storage, retention, replacement, deletion, or privacy claims—verify current terms before use.
上传财务报表进行分析前，应先建立受控资料包，而不是把收件箱原样丢给工具。保留不可覆盖的来源副本；优先选择监管机构或发行人原件；纳入资产负债表、利润表、现金流量表、权益变动表、会计政策与相关附注；为每份文件标明主体、表格类型、提交日、财政期间、币种、单位、审计状态及修订范围，并记录所有排除项。若来源是扫描件，保留图像原件，把 OCR 更正另列日志。删除不必要敏感信息，并确认自己有权上传。资料包只回答一个边界清楚的问题。上传后，用原件抽查主体、页码定位、正负号、单位、列与合计。若产品当前公开说明没有写明格式限制、存储、保留、替换或删除机制，就不能自行补充承诺，必须在使用前另行核实。
Quarantine the inbox before choosing evidence先隔离收件箱，再选择证据
A “financials” folder may mix a glossy annual report, filed 10-K, later 10-K/A, earnings release, screenshots, transformed spreadsheets, and duplicates. Preserve incoming files unchanged, then inventory publisher, filing date, period, and any later document that changes them.
名为“financials”的文件夹可能同时装有宣传版年报、正式提交的 10-K、后续 10-K/A、业绩新闻稿、截图、从数据供应商复制的表格，以及重复下载的同一 PDF。这些材料不能互换。所谓“隔离”，就是先原样保留所有来件，不改名、不覆盖，然后另建工作清单。目标是建立来源链：每份材料由谁发布、何时提交或发布、覆盖哪个期间，以及是否存在另一份文件改变了它。
- Freeze an intake copy and record acquisition URL and date. Test duplicates; similar names prove nothing.
- Read legal issuer, regulator ID, form, filing date, period end, and amendment marker from the document.
- Classify each item as filing, issuer supplement, third-party transformation, working paper, or unidentified.
- Mark duplicates, apparent replacements, extracts, and orphan pages. An amendment may change only one item.
- Build a working area linked to originals. Put corrections in a log or derived copy.
- 冻结一份原始接收副本，记录取得网址与访问日期；若本地流程支持，可用校验值或其他方法识别重复文件。不能只因文件名相似就删除其中一个。
- 从文件正文而不是文件夹名称中确认发行人法定名称、监管标识、申报类型、提交日、期末日和修订标记。
- 把材料分类为正式申报、发行人补充材料、第三方转换、分析者工作底稿或身份不明文件。电子表格更容易解析，不代表它的证据等级高于申报原件。
- 标记完全重复、疑似替代、局部摘录和无上下文单页。“最新”并不足够：修订文件可能只修改一个项目，而没有重新发布整份报告。
- 建立指回冻结原件的清洁工作区。任何纠正都写入日志或派生副本，不能在来源文件中无痕修改。
For a U.S. registrant, use EDGAR for filings and label issuer presentations separately. A 10-K has audited annual statements; a 10-Q has unaudited interim statements; “/A” denotes an amendment. Elsewhere, use the applicable registry and reporting basis. Record the actual retrieval route.
权威性要针对具体问题判断对美国注册发行人而言，EDGAR 是正式申报档案，发行人网站则常便于取得演示材料。10-K 包含经审计年度报表，10-Q 包含未经审计中期报表，“/A”表示修订。若研究其他法域或私人公司，应改用适用登记系统与报告基础。清单必须记录实际取得路径，不能把“来自互联网”当成来源说明。
Normalize the packet without erasing provenance规范化资料包，但不抹去来源痕迹
A filename should carry identity without rewriting history: sequence_issuer_period_form_filed-date_role.ext. In the manifest retain original name, URL, retrieval date, hash, issuer, period, filing date, currency, unit, role, amendment scope, page status, and upload decision.
有用的文件名用于携带身份，而不是改写历史。可以采用“序号_发行人_期间_表格_提交日_角色.扩展名”的格式。更丰富的信息放在 manifest：原文件名、来源网址、取得日、文件校验值、发行人、期间、提交日、币种、显示单位、文件角色、修订范围、页码状态与是否纳入上传。原文件名也应保留。“final_v7_revised.pdf”只有在清单说明它是什么、替代什么之后才有意义。
Record units per table. One filing may use millions, currency units per share, and thousands in a supplement. Preserve reported values; put normalized values and formulas in separate columns.
单位映射表按表格而不是只按文件记录单位。同一申报可能以百万元列主表、以货币元列每股数据、以千元列补充表。必须保留已披露数值，把规范化数值放在另一列，并写出换算公式。
Record viewer page plus printed page or section anchor. Crops reset numbering; HTML may lack stable pages. Another reviewer must be able to reopen the passage.
页码映射表同时记录阅读器页码与印刷页码或章节锚点。裁切扫描件会重置页码，HTML 申报也可能没有稳定页数。定位必须让另一位复核者能重新打开同一段落。
Log image locator, OCR text, correction, reviewer, and date. Check parentheses, minus signs, decimals, headers, and drifting columns. Never replace the image source.
OCR 例外日志每项重要纠正都记录图像定位、OCR 文本、更正文本、复核者与日期。优先检查括号负数、负号、小数点、重复表头、上标和跨页错位列。图像来源永远不能被覆盖。
Upload only necessary, authorized material. Remove unrelated identifiers, credentials, account details, comments, and hidden tabs after preserving an authorized internal original. A public filing does not make bundled working papers public.
隐私最小化只在获得授权时上传回答既定问题所必需的内容。保留获授权的内部原件后，移除无关个人标识、凭据、账户信息、批注和隐藏工作表。主申报公开，并不意味着同一文件夹内所有工作底稿都已公开。
Formats, size limits, password protection, storage, retention, training use, sharing, replacement, and deletion are product-policy questions. Check the current interface, terms, privacy notice, or support. If not established, mark “not verified” and withhold sensitive files.
不要猜测平台限制支持格式、最大文件大小、文件数量、密码保护、存储位置、保留期限、是否用于模型训练、共享、替换与删除都属于产品政策问题，应查看当前界面、条款、隐私说明或支持答复。若公开资料无法确认，就标为“未核实”并暂不上传敏感文件，不能把沉默解释成承诺。
Worked rescue: BorealRelay’s disorderly folder文件救援演练：整理 BorealRelay 的混乱文件夹
BorealRelay Medical Systems is fictional; all records and figures are illustrative. The task is to test whether gross debt rose from December 31, 20X5 to June 30, 20X6, and identify evidence still needed for the next twelve months of maturities. Six incoming objects yield four active files.
BorealRelay Medical Systems 是一家虚构公司，以下文件名、日期、定位与数字全部用于演示，不代表任何真实发行人。任务边界很窄：判断已报告总债务从 20X5 年 12 月 31 日至 20X6 年 6 月 30 日是否增加，并指出评估未来十二个月到期额还缺什么证据。来件文件夹有六个看似可信的对象，但只有四个进入有效资料包。
| Incoming item | Finding | Controlled action |
|---|---|---|
| AnnualReport_FINAL.pdf | Issuer booklet; notes stop after p.72 | Supplemental, not authority |
| Two 10K_download PDFs | Same EDGAR filing; identical checksum | One working copy; log duplicate |
| 10K_A.pdf | March 3; controls item only | Keep beside 10-K; scoped amendment |
| Q2.xlsx | Analyst export; no source | Exclude from evidence |
| Q2_10Q.html | August 6 filing; debt note complete | Interim authority |
| scan_notes.pdf | Partial; (18,000) loses parentheses | Exclude; log defect |
| 来件 | 发现 | 受控处理 |
|---|---|---|
| AnnualReport_FINAL.pdf | 发行人宣传册；有主表，但附注在第 72 页后截断 | 仅作补充，不作为年度权威版本 |
| 10K_download.pdf 与 10K_download(2).pdf | 同一 EDGAR 申报，校验值相同 | 保留一个有效工作副本，并在 manifest 记录重复判断 |
| 10K_A.pdf | 20X6 年 3 月 3 日提交，只修订控制事项 | 与 10-K 并列保留，不视为整份替代 |
| Q2.xlsx | 分析者导出，单位为 CU 千，来源字段为空 | 排除出证据层，只可作为草稿对照 |
| Q2_10Q.html | 正式申报，8 月 6 日提交；主表和债务附注完整 | 作为中期权威版本 |
| scan_notes.pdf | 只有第 35–64 页；OCR 把 (18,000) 读成 18,000，且缺债务页 | 不参与计算；记录缺陷并原样保存 |
The active manifest labels the 20X5 10-K as authority, its 10-K/A as controls-only, the Q2 10-Q as interim authority, and the annual report as supplemental. These are local roles, not promised upload formats. Check the current interface and prepare only authorized inputs.
整理后的有效 manifest 包含：01_BorealRelay_20X5_10-K_filed-20X6-02-18_authority.html、02_BorealRelay_20X5_10-K-A_filed-20X6-03-03_controls-only.html、03_BorealRelay_20X6-Q2_10-Q_filed-20X6-08-06_authority.html，以及 04_BorealRelay_20X5_annual-report_supplemental.pdf。这些名称说明本地文件角色，并不代表某个上传界面承诺支持这些格式。实际上传前，复核者仍须查看当时界面支持的输入，并据此只准备已获授权的材料。
Use one question as a packet acceptance test用一个问题验收整个资料包
“Analyze the statements” cannot reveal whether omissions matter. BorealRelay’s debt question tests identity, dates, units, classification, and notes. Invented facts: the 10-K reports CU12m current and CU88m long-term debt at December 31; the Q2 10-Q reports CU18,000k and CU102,000k at June 30.
“分析这些报表”过于宽泛，无法暴露缺失文件是否重要。BorealRelay 的债务问题迫使资料包证明主体、日期、单位、分类与附注覆盖。演示中的 10-K 在 20X5 年 12 月 31 日报告流动债务 CU12 百万、长期债务 CU88 百万；Q2 10-Q 的显示单位为 CU 千，在 20X6 年 6 月 30 日报告流动债务 CU18,000 千、长期债务 CU102,000 千。这些都只是本演练内的虚构“已披露事实”。
| Evidence layer | BorealRelay record |
|---|---|
| Reported facts | 20X5: CU12m current + CU88m long-term. Q2: CU18,000k + CU102,000k. |
| Calculation | 12 + 88 = CU100m; (18,000 + 102,000)k = CU120m; 20 ÷ 100 = 20.0%. |
| Assumption | Debt categories and lease treatment are consistent after note review. |
| Judgment | Reported gross debt rose 20.0%; cause and risk remain unanswered. |
| Missing evidence | Maturity schedule, refinancing terms, facility conditions, and covenant definitions. |
| 证据层 | BorealRelay 记录 |
|---|---|
| 已披露事实 | 20X5：流动 CU12 百万＋长期 CU88 百万；20X6 Q2：流动 CU18,000 千＋长期 CU102,000 千。日期与单位来自报表表头。 |
| 计算 | 20X5 总债务＝12＋88＝CU100 百万；Q2＝（18,000＋102,000）千＝CU120 百万；变化＝CU20 百万，20÷100＝20.0%。 |
| 假设 | 阅读两期债务附注后，两类债务可比较；融资租赁负债在两期均一致纳入或一致排除。 |
| 判断 | 在上述口径下，已报告总债务增加 20.0%；方向有支持，但变化原因和风险并不能由该计算回答。 |
| 缺失证据 | 判断未来十二个月到期压力仍需完整合同到期表、期后再融资条款、未使用额度条件及契约定义。 |
Reading 120,000 as CU120,000m overstates debt 1,000 times. Keep “CU thousands” beside inputs and show conversion. Current plus long-term debt must match the declared scope; otherwise locate leases, overdrafts, or excluded classes.
单位检查避免千倍错误若把 120,000 误读成 CU120,000 百万，会把 Q2 债务夸大 1,000 倍。输出应在来源数值旁保留“CU 千”并展示换算，而不是只给出光滑的 CU120 百万结果。还要检查小计：流动债务加长期债务必须等于声明的总债务口径；若不相等，应停止并寻找租赁、透支或其他被排除类别。
Sample the upload before reviewing the narrative先抽样验收上传结果，再阅读叙述
Begin with cells and passages that can fail differently, not the conclusion. Sampling cannot prove perfection, but it can reject an unreliable run. Save the prompt, manifest, timestamp, and displayed tool version so later replacements remain distinguishable.
不要先看生成结论，而要先选取一小组可能以不同方式出错的单元格和段落。抽样不能证明整个资料包完美，却能迅速拒绝一次不可靠的运行。应保存提示语、上传 manifest、分析时间戳，以及界面若有显示的工具版本，避免后来替换文件或纠正 OCR 后与第一次运行混淆。
- Identity: compare issuer, form, period end, and filing date with authoritative covers.
- Locator: reopen one balance, flow, policy, and note table at the returned locations.
- Glyph: check parentheses, a decimal, percentage, and footnote marker.
- Column: distinguish current, comparative, quarter-only, year-to-date, and point-in-time values.
- Arithmetic: recompute a subtotal and unit conversion from located inputs.
- Context: read around citations and restore omitted qualifications or definitions.
- 主体抽样：要求返回发行人法定名称、申报类型、财政期末和提交日，并逐份对照权威文件封面。
- 定位抽样：分别要求一个余额、一个期间流量、一项会计政策和一张附注表的准确章节或页码，然后打开四个位置。
- 字符抽样：检查一个括号负数、一个小数、一个百分比和一个脚注标记，扫描材料尤其要查。
- 列抽样：核对一个当期值和一个比较值，并确认每个数是单季、年初至今还是时点余额。
- 算术抽样：根据显示输入重新计算一个小计，以及 CU 千到 CU 百万的换算。输入无法定位的答案不能通过。
- 上下文抽样：阅读引文前后段落，把生成摘要遗漏的限定、定义与例外写入记录。
When a sample fails, inspect the class: a wrong sign may be OCR-wide; a wrong comparative may reveal shifted columns; a booklet citation may reveal source-ranking failure. Correct the derived input, increment the packet version, rerun, and resample. Retain failed-run history when policy permits.
任何一个样本失败时，先判断失败类别，再决定是否纠正单一数字。一个正负号错误可能说明整份 OCR 都有问题；一个比较期数值错误可能意味着所有表格列都发生错位；引用宣传年报而不是申报文件，则可能说明来源排序失效。应替换或纠正派生输入，递增资料包版本，重新运行问题并再次抽样。若治理规则允许，失败运行应保留在复核历史中，因为它能解释答案为何改变。

Record local owner, review date, access, and end-of-purpose action. Platform behavior is separate: “deletion requested,” “confirmed,” “retention undocumented,” and “local source retained” differ. A cleared browser view does not prove deletion. Follow documented controls and organizational duties.
台账还应记录本地保留责任人、复核日期、访问范围，以及研究目的结束时应采取的动作。平台端行为必须作为独立字段。“已请求删除”“已确认删除”“保留期未公开”和“依据本地政策保留来源”是四种不同事实。文件从浏览器视图消失，不代表能够断言它已被删除。处理时要遵循工具当前有文档支持的控制方式和所在组织的义务。
For a new filing, update intake, authority spine, affected manifest fields, and acceptance samples. A later BorealRelay refinancing updates the maturity question, not the historical CU100m and CU120m balances. Versioning preserves relevance and reproducibility.
未来新申报到来时，不必再从混乱文件夹重建。把它加入隔离区，判断是否改变权威版本骨架，只更新受影响的 manifest 字段，再执行同一组验收样本。对 BorealRelay 而言，后续再融资申报会更新到期问题，但不会改变两个指定日期总债务分别为 CU100 百万与 CU120 百万这一历史记录。版本控制同时保护当前相关性和历史可复现性。
Use Stock Explained only after the packet passes local QA本地文件质检通过后，再使用 Stock Explained
InfiniSynapse operates Stock Explained and publishes this guide. Its verified public page describes users providing financial reports, financial data, or research materials; a plain-language brief with data support; and separation of facts, calculations, inferences, and gaps. It does not establish every format, size limit, retention term, deletion mechanism, or privacy property. Check current documentation, especially for non-public material.
Upload an authorized active packet and one bounded question through a currently supported route. Require document, period, unit, and locator for decisive figures. Reopen locations, recalculate material arithmetic, and compare output with the local manifest. Preserve missing notes as uncertainty. The tool cannot make an incomplete packet complete or an unchecked extraction audited fact.
InfiniSynapse 运营 Stock Explained 并发布本指南。其公开页面经核验后能够支持以下描述：用户提供财报、财务数据或研究资料；工具把材料整理为通俗公司说明，为结论附上数据依据，并区分事实、计算、推断和信息缺口。这证明了文件复核使用场景，但没有证明所有支持格式、文件大小限制、保留期限、删除机制或隐私属性。上传前必须查看当前产品说明，非公开材料尤其如此。
先准备已获授权且处于有效状态的资料包和一个边界明确的问题，再通过当时支持的路径上传。要求输出为每个决定性数字说明文件、期间、单位和来源位置；逐一打开这些位置，重算重要算术，并把输出文件列表与本地 manifest 对照。附注缺失时应保留不确定性。Stock Explained 可以帮助整理已提供证据，却不能让不完整资料包自动完整，也不能把未经核验的抽取变成审计事实。
Verify current upload terms, prepare an authorized manifest and one question, then check every material output against the authoritative source.
先核对当前上传条款，准备已获授权的 manifest 和一个问题，再把所有重要输出回查到权威来源。
Open Stock Explained打开“一眼看懂这只股票”Questions that arise while preparing an upload整理上传资料包时会遇到的具体问题
For a U.S. domestic registrant, use the filed 10-K as annual authority and label an issuer annual report as supplemental when appropriate. The documents may overlap, but a booklet can omit filing sections. Compare identity, date, statements, notes, and audit scope—not cover titles.
应该上传年度报告还是 10-K？对美国本土注册发行人，应把正式提交的 10-K 作为年度权威版本；发行人年度报告只有在提供额外背景时才作为明确标注的补充材料。两者有时重合，有时宣传版报告会省略申报章节或附注。应比较主体、提交日、报表、附注和审计覆盖，不能只看封面名称。
No. “/A” identifies an amendment; its contents define what changed. Keep original and amendment together, record amended items, and replace only that scope unless the filing expressly republishes more.
10-K/A 是否会替代资料包中的整份 10-K？不会自动替代。“/A”说明它是修订文件，但具体改变范围要由封面和正文确定。应把原件与修订并列，记录被修改项目；除非文件明确重新发布或替代更多内容，否则只在该范围内采用修订披露。
Perhaps for an extraction test, rarely for analysis. Notes define policies, classifications, roll-forwards, commitments, and estimates. Use the complete filing or a documented subset whose omissions cannot affect the narrow question; otherwise label the answer incomplete.
只上传三张主表所在页面可以吗？这可能足以测试视觉抽取，却很少足以支撑可靠分析。附注定义政策、分类、滚动、承诺、估计与后续变化。应选择完整申报，或使用一组经记录且其省略内容不影响窄问题的子集；否则必须把答案标为不完整。
Preserve the scan; record image page, OCR output, correction, reviewer, and date; then verify pixels and subtotal. Corrected text remains derived. Check similar glyphs because one failure may be systematic.
PDF 是扫描件，OCR 又把负数识别错了，怎么办？保留扫描原件，记录图像页、OCR 输出、更正值、复核者和日期，再根据像素与相邻小计核实。更正文本只能作为派生文件。还要在抽样表格中检查类似字符，因为一个错误可能暴露系统性抽取问题。
Use current terms, privacy notice, documented controls, or support. A cleared screen does not prove deletion; silence does not define retention. If unverified, minimize the upload, use public filings, or pause before sending sensitive material.
如何知道上传文件会被保留还是删除？查看产品当前条款、隐私说明、有文档支持的控制功能或支持答复。不能因界面清空就推断已经删除，也不能因没有说明就推断保留期限。若仍无法确认，应标为未核实，缩小上传范围、改用公开申报，或在发送敏感材料前暂停。
Rerun when an amendment, restatement, later filing, unit correction, added note, or material OCR fix changes the evidence. Increment the packet version and preserve the old cutoff. A cosmetic rename is not new analysis.
什么时候应该替换文件并重新分析？当权威修订、重述、后续申报、单位纠正、补齐的附注或重要 OCR 错误改变了问题所用证据时，应递增资料包版本并重新运行，同时保留此前截止日。仅仅美化文件名，并不能把结果包装成新的分析。
