…word that is not a designation The trailing-designation lookahead accepted any word of the upper case list, so "envie-me, cpf" became "Envie-ME, CPF", and the slash-joined designation branch upper cased a leading "me". ME is now upper case only as the last word or right before an adjacent company designation, and never when a hyphen or an apostrophe attaches it to the previous word.
…back to BrasilAPI BrasilAPI keeps publishing institutions Bacen has dropped, so on that fallback a code of LEGACY_BANKS reached the dataset as a current one. The curated row now wins and the code stays in LEGACY_BANK_CODES; the Bacen source is still the only proof that a code is back. Output unchanged.

…shes Legacy codes stay in the package only when the official source publishes their history, as the CONCLA correspondence does for the legal natures. The Bacen list publishes the current participants alone, so the 29 codes that left it, `Bank.legacy`, `GetBanksParams`, `LEGACY_BANK_CODES` and the `build-bank` internal are removed; a code that left the list is unknown to the lookups and to `isValidBankAccount`, like any other unassigned code.
… config with the toolchain The README bundle badges become a static one (bundlephobia reports the whole package, not the `isValidCpf` import, and badgen rate-limits), the development section follows CONTRIBUTING.md (`vp` is a dependency, nothing global), the migration guide stops citing Biome and lists the gates the project actually runs, the changelog header says release-please generates it, the release config drops the `deps` type commitlint rejects and hides the Dependabot bumps, the mutation workflow publishes the score of `main` to the Stryker dashboard with the key the repo already has, and `live-tests.yml` loses a default.

…ignation after ME `ME` was upper case before `EPP` and `S.A.` but not before `S/A` or `S/S`, because the lookahead compared only the next token (`"s"`) with the company designations. It now forms the pair across a lone slash, so `"fulano me s/a"` is `"Fulano ME S/A"`, while `"s a"`, `"s / a"` and a trailing `"s/"` keep `ME` as the ordinary word.
`fetchWithRetry` compared the attempt with `===`, so a fractional, `NaN` or infinite `retries` never reached the last attempt while the errors stayed retryable. The guard now requires an integer of zero or greater and the loop exits on `>=`. The retry suite drops its only recursion and gives the "throws without waiting" case a bound that survives a loaded CI runner.
…d npm run bench `runHooks`, `deepEqual` and `objectMatches` in the Deno runtime shim called themselves; they now iterate with a pending list, as the rest of the code base does. The benchmark blocks the shims reference through `npm run bench` finally have that script (`vitest bench --run`), the shim comment stops citing a `test:types` script that never existed, and the `ci` script, a duplicate of `check` nothing called, is gone.
…nitizers make dead Output unchanged, verified property by property against the previous build. The CPF, CNPJ, PIS and processo jurídico check digits now come from one `_internals/calculate-*` each, used by the validator and the generator alike; `isValidCnpj` reads its value through `sanitizeToAlphanumeric` instead of a hand loop; `isValidBoleto` stops repeating the arrecadação prefix test the parser does; `sanitizeToAscii` drops a step the next one already covered; the separators regex, the legacy legal nature test and the state code list become shared internals (`STATE_CODES` is now emitted by `scripts/states.ts`, and `isValidRegistroProfissional` and `getCepInfoByAddress` stop pulling the whole states table, 2.1 KB less each); `HolidayDateRule` is a union, so the unreachable throw goes; the lookups read their tables with `Object.hasOwn`; caches are plain constants; `fetchSortedRecord` moves next to the scripts that use it; the test-only bank code export is gone; and the CONTRIBUTING table row loses a trailing space the formatter rejected.

…e own-property lookup `6d0dce2` moved `getMunicipalities` to `Object.hasOwn(CITIES_DATA, stateCode)`, which converts its key to a property key first, so an object without a primitive value (`Object.create(null)`) threw where the previous scan over the states table returned `[]`. The string check comes first, as in `getCities`, with the case pinned in the municipalities and holidays suites.

- Around line 31-32: Update the exported parseCertidao and parseNfeKey functions
to restore their structured Certidao | null and NfeKey | null return contracts,
including parsed fields and null for invalid or absent input. Move or retain
digit-only normalization under separate APIs rather than changing either
parser’s established behavior, and ensure the exports in src/index.ts continue

- Around line 29-30: Update the exported parseIban function to preserve the
structured Iban | null result expected by consumers, including fields such as
account and owner, rather than returning a normalized string. Move the current
sanitizeToAlphanumeric and length-truncation behavior into a separately named
string-normalization helper, and keep getIbanInfo only if it delegates
consistently without replacing parseIban’s contract.

…m the library range
The iterative `deepEqual` and `objectMatches` queued the same pair again on every visit of a self-referencing object, so `toEqual` on two cyclic values never ended (the recursive version overflowed the stack instead). A pair is recorded the first time it is compared and skipped after that.

The page follows the v5 template: `docsify@5/dist` for the core script and the search plugin (pinned to the major, so patch releases arrive on their own), the core theme with the dark add-on always on (the look the site had with docsify-themeable, which stays on v4), the palette green as `--theme-color`, the cover on the page background instead of the default gradient, the emoji plugin dropped (built into docsify since 4.13), `docsify-copy-code@3` from jsDelivr, and a sidebar depth of 3 for the grouped utilities reference.
The 138 sections of `utilities.md` (EN and pt-BR alike) now sit under 25 family headings (CPF, CNPJ, CEP and address, Pix, phone, holidays and business days, ...); the five utilities that form no family (`isValidIe`, `isValidEmail`, `isValidCreditCard`, `isValidRegistroProfissional`, `isValidVin`) stay flat at the end. Function anchors are unchanged, since docsify slugs the heading text, not its level. `scripts/llms.ts` reads a function section from a `##` or `###` heading that is a bare identifier and skips the family headings. The input-handling note at the top of the page is gone; every section states its own behaviour.
Subpath imports and lazy loading of the heavy entries next to the tree-shaking section, the families 2.4.0 added, the object form of `isValidIe`, the `getMunicipality` and `getCities` deprecations with their replacements, and a checklist of the 2.4.0 deprecations to clear before v3 (`*Options` aliases, positional `isValidIe`, `widenet`). Every example was run against the built package.

What does this PR do?
Part 18 of 18 of the 2.4.0 release stack (main <- stack/01-tooling <- ... <- stack/11-testing). The second half of the third review round plus rounds four and five (three and then three independent audits of every export against the primary sources, a browser check of the hosts that block non-browser clients, an independent re-derivation of every check-digit algorithm, an execution of every documented example and a citation-by-citation read of the pages). Behaviour fixes, each on the approved list with literal tests: the state holiday table audited law by law (Santa Catarina's Sunday transfers per the 1999, 2004 and 2005 laws, Goiás, the DF Corpus Christi, Paraíba until 2015, Alagoas from 2024);
addBusinessDays(date, amount, options?), the newsubBusinessDaysanddifferenceInBusinessDays(later, earlier, options?)follow the date-fns signatures and shareBusinessDayOptions, andisBusinessDayrejects a non-string state code likeisHoliday;capitalizekeeps company designations, roman numerals and a state code after/upper case by default;formatCurrencycoerces a non-string like 2.3.0 without throwing andconvertCurrencyToWordsreads the cents from the decimal notation; the words converters always return lower case (thecaseoption is gone from the new types);formatCnae/formatNcmgainpad;isValidEmailcaps the final label at 63 letters;getBoletoInfonever resolves a factor to a date before the scheme;isValidServicePhonedrops 112/911 and adds 141 per the Anatel acts;isValidCst,isValidCaepf, the CNS/CEI separators and the Pix Saque facilitator on a dynamic payload follow their specifications;getAddressInfoByCep/getCepInfoByAddressreject with their typed errors instead of rawTypeErrors and map a BrasilAPI 404 to not-found;CepAddressInfodeclares the fields ViaCEP now returns. Package: every subpath re-exports the types its signatures use (validated by API Extractor and a three-mode consumer compile) and atypesVersionsblock makes the subpaths resolvable undermoduleResolution: node. Docs: every option used in an example is described, every citation points at the page that carries the claim (Resolução CONTRAN 968/2022 and its annexes, ADE Cofis 10/2026, the CNJ Provimentos, the Anatel acts, CNAE-Subclasses 2.3, Ajustes SINIEF 36/19, 03/20 and 39/25), the changelog hides the CI and build sections and every subject reads as a consumer-facing entry. The lychee link check was removed at the maintainer's request; the citations are verified by hand. Closing with what the six-library comparison (python, ruby, go, rust, dotnet) showed the JavaScript package was missing:generateCnpjaccepts abranch(número de ordem) block,generateRenavamis new,getLegalNaturereturns the CONCLA category andgetLegalNaturesByCategorylists a category,isValidMobilePhone/isValidPhoneunderversion: 2accept 7, 8 and 9 as the first digit and reject the 700 satellite series (Res. Anatel 749/2022, art. 12); and the workflows reference the setup action with GitHub's self-repository$/syntax (zizmor). The new formatters (formatCnae,formatNcm,formatNfeKey,formatCertidao,formatIban) now mask progressively and read only the digits or letters, the input-mask contract offormatCpf,formatLegalNaturegainspad, and no formatter throws on a value without a string conversion. A convention audit of the 60 new exports against the 2.3.0 ones then aligned them: numeric and string codes are padded the same way in the CBO/CNAE/NCM/CST lookups, the NF-e key, IBAN and credit card accept the CPF mask separators at their printed groups, credit card and VIN reject a repeated value,GeneratePixPayloadOptions,FormatNfeKeyOptions,isValidRegistroProfissional({ value, council }),getBoletoInforeturnsnull, the five structured readers are namedget*Info(getCertidaoInfo,getIbanInfo,getNfeKeyInfo,getPixKeyInfo,getPixPayloadInfo),AreaCodeInfocarriesregionName/regionCode, and every new family gains its mask-strippingparse*. The last pass moved the toolchain to TypeScript 7 (vitest stays on the 4.1 that Vite+ ships until Stryker supports 5), turned the three recursions into loops, cited each state holiday's law, applied theParams/Optionsnaming rule (eight 2.3.0 type names kept as deprecated aliases) withisValidIe({ value, stateCode }), kept the retired legal-nature codes and the 29 banks that left the Bacen list aslegacyentries, madegenerateLicensePlatefall back to the default for an unknown format, and simplified the internals with the bundle 1.7 KB smaller.Commits in this part (99)
