真实的银行对账单包含数十种格式怪癖，足以让朴素的解析器失效。
Missing Year in Dates
Statements omit the year from transaction dates (e.g., "03/15" instead of "03/15/2025"), which makes it impossible to sort or reconcile without guessing.
出现在 4 份对账单中Blank Dates for Same-Day Transactions
Statements only print the date on the first transaction of each day — the rest have blank date cells.
出现在 1 份对账单中Plus/Minus Sign After the Amount
Statements place the plus or minus sign after the amount (e.g., "123.45-" instead of "-123.45").
出现在 1 份对账单中Currency Symbols Breaking Numeric Parsing
Statements embed currency symbols (e.g., "$1,234.56") directly in amount cells, which breaks numeric parsing in Excel and most CSV importers.
出现在 2 份对账单中No Visible Table Lines or Borders
Statements sometimes lack clear row or column lines.
出现在 1 份对账单中Separate Credit & Debit Columns
Statements use separate Credit and Debit columns in some formats, while others use a single Amount column with signs.
出现在 10 份对账单中Page Headers & Footers Mixed with Data
Page headers and footers contain bank logos, page numbers, and disclaimers that can interfere with transaction extraction.
出现在 1 份对账单中No Selectable Text (Scanned PDF)
Statements are often image-based PDFs with no selectable text, so copy-paste and standard PDF extractors return nothing useful.

Printed content and every ground-truth answer are unchanged. 原始 PDF sha256： 7f96da7316b2b540f2f8ecfc4151cd242a501be3ed84204a15bfbbe3c355531b. 已被替代为： 8a5b0e296d5d9ffaccfe6e8d99e0b52f7f60db76db54132c8c9ce6b8cbd52720. 内容未发生变化 — 针对原始 PDF 生成的解析结果或分数仍然有效，但曾以已被替代的哈希值为键。请重新以新哈希值为键，无需重新解析。

bsb-004（Silk Road Banking (Hong Kong)）于 2026-08-07 重新发布。 Reissued to correct errors in the original statement. The second account is now denominated in USD, with a disclosed FX rate. 原始 PDF sha256： e93cacdb23195adefdf13ef4ba9528f55454c6fb2dc83624fe9c5077c5bc6455. 已被替代为： 522f8c9c92cb567580ffca4ac5ff9d4caea7d831764671de0ab8ae0878e513c2. 针对原始 PDF 生成的解析结果或分数不可比较。请对重新发布的 PDF 重新解析。
bsb-004（Silk Road Banking (Hong Kong)）于 2026-08-11 重新发布。 Reissued to fix the same generator reproducibility bug as the other released statements, plus a generator fix to how ground-truth account identity is derived: the account name no longer bakes in the account number, which lets a parser that correctly componentizes the printed heading exact-match cross-engine. Printed content (including the heading) is unchanged. 原始 PDF sha256： 522f8c9c92cb567580ffca4ac5ff9d4caea7d831764671de0ab8ae0878e513c2. 已被替代为： 0a4201b0e1a9c9ed834a2dce898a97ef8bac2b959ae6e3eb041c59328e0b19d1. 内容未发生变化 — 针对原始 PDF 生成的解析结果或分数仍然有效，但曾以已被替代的哈希值为键。请重新以新哈希值为键，无需重新解析。

Printed content and every ground-truth answer are unchanged. 原始 PDF sha256： 01a26c767b9488e45b358b329e2c9ea3d9fba05878a1963da06fde899827debb. 已被替代为： 8919aa5abdb06d377898e5cc78751661fcc80a25a89a477af49ceb0f0d7fe143. 内容未发生变化 — 针对原始 PDF 生成的解析结果或分数仍然有效，但曾以已被替代的哈希值为键。请重新以新哈希值为键，无需重新解析。
bsb-001（Straits Capital (Singapore)）于 2026-08-14 重新发布。 Reissued to fix account numbers that were previously a static, non-random digit string shared by every synthetic statement for that banking tag. Account numbers now come from a country-keyed format table (#4931). 原始 PDF sha256： 8a5b0e296d5d9ffaccfe6e8d99e0b52f7f60db76db54132c8c9ce6b8cbd52720. 已被替代为： d3d5071b90a33272f31bab5c5660d78b2ae29d2c6e1720477f5e8b167f73e843. 针对原始 PDF 生成的解析结果或分数不可比较。请对重新发布的 PDF 重新解析。

bsb-003（Continental Trust (Netherlands)）于 2026-08-14 重新发布。 Reissued to fix the account number: NL is an IBAN country, but the old template randomized a two-letter "country code" instead of emitting NL's literal IBAN prefix, and the checksum was never a valid ISO 7064 mod-97-10 IBAN check digit. Account numbers now come from a country-keyed format table that emits a real, check-digit-valid IBAN for NL (#4931). 原始 PDF sha256： 4bad73296bdbcf7142b62c8af421527f88d1d3a6865617e9fea48e6f51c704a1. 已被替代为： 4945bcda107e6d7845850e728b90c4dba1cb11de5a13356b0794df349e5527c2. 针对原始 PDF 生成的解析结果或分数不可比较。请对重新发布的 PDF 重新解析。
bsb-004（Silk Road Banking (Hong Kong)）于 2026-08-14 重新发布。 Reissued to fix account numbers that were previously a static, non-random digit string shared by every synthetic statement for that banking tag. Hong Kong has no single documented national account-number scheme, so the new generic digit format is honestly noted as such rather than citing a fabricated standard. Account numbers now come from a country-keyed format table (#4931). 原始 PDF sha256： 0a4201b0e1a9c9ed834a2dce898a97ef8bac2b959ae6e3eb041c59328e0b19d1. 已被替代为： 67a5b862696fc06e675db53867be6fcc71a4ecc13998193e8b45e2cd63371051. 针对原始 PDF 生成的解析结果或分数不可比较。请对重新发布的 PDF 重新解析。
bsb-005（Harbour Bank (Canada)）于 2026-08-14 重新发布。 Reissued to fix the account number: Canada has no IBAN, but the old template printed a French IBAN (inherited from the base `fr.json` dictionary — format was keyed by language, not jurisdiction). Account numbers are now keyed by country, so `fr-CA` prints Canada's 5-digit-transit + 3-digit-institution + 7-digit-account format instead of France's IBAN (#4931). 原始 PDF sha256： 8919aa5abdb06d377898e5cc78751661fcc80a25a89a477af49ceb0f0d7fe143. 已被替代为： a5cc2a7d210bc657c55b44ac159c5d10b2d71553f3646ce17a64051f918fd960. 针对原始 PDF 生成的解析结果或分数不可比较。请对重新发布的 PDF 重新解析。
