In `@src/_internals/mod11/mod11.ts`:
- Line 37: Validate options.maxWeight before the Mod11 check-digit weight loop
uses it: reject any value that is not finite, is not an integer, or is below 2,
while preserving DEFAULT_MAX_WEIGHT when the option is absent.
In `@src/parse-cep/parse-cep.ts`:
- Line 1: Restore the CEP length dependency used by parseCep: add a supported
constants module exporting CEP_LENGTH at the path referenced by parse-cep.ts, or
update the import to reuse an existing CEP length constant. Ensure both parseCep
and the src/index.ts export resolve without changing their public behavior.
In `@src/parse-cpf/parse-cpf.ts`:
- Line 1: Add the missing shared constants modules referenced by the CPF, PIS,
and processo jurídico parsers, defining CPF_LENGTH, PIS_LENGTH, and
PROCESSO_JURIDICO_LENGTH with the expected values; alternatively, update those
imports and all corresponding references to use existing LENGTH constants while
preserving current validation behavior.

Generalize mod11 with a variant/maxWeight option (boleto, arrecadacao, bank). Extract the shared isRepeatedDigits helper into its own folder; simplify isValidRenavam/isValidEmail now that helpers guarantee input shape. Move the CEP, CPF, PIS and processo juridico lengths shared by several utils to src/_internals/constants so later commits can import them without duplication.
Add the shared isNullish helper. format*/parse* functions now return "" instead of throwing on null/undefined input. Applied here to formatCnh, parseCnh, parseCep, parseCpf, parsePis, formatPis, parseProcessoJuridico and parseLegalNature; the remaining format*/parse*/isValid*/ generate* functions get the same guard in their own per-util commits.

Restore the export modifier on isRetryableFetchError.
The "./*" export pattern permits deep imports. The previous version exported isRetryableFetchError, but the current declaration is local. This breaks consumers that import the helper directly. Restore export const isRetryableFetchError.

Not changing this. src/_internals is not an entry point: the "./*" export maps to the per-util bundles that vp pack emits from src/, and _internals is bundled into them, so @brazilian-utils/brazilian-utils/fetch-with-retry never existed. knip flagged the export as unused, which is why it went.
fetchWithRetry: use a plain array literal instead of a module-scope new Set(). A top-level side-effecting statement pins its module into every consumer bundle even when only one unrelated util is imported; see the ci(tree-shaking) guard.
Move the first/second check-digit calculations out of isValidCnh into _internals/calculate-cnh-first-verifier and calculate-cnh-second-verifier. generateCnh reuses the same helpers; no behavior change.
Strips diacritics (accents, tildes, cedillas) via Unicode NFD decomposition,
e.g. removeAccents("São Paulo") -> "Sao Paulo".
Lands with the internals because the CEP, municipality and state lookups depend on it.

src/_internalsgroundwork the rest of the stack builds on:mod11withboleto,arrecadacaoandbankvariants, sharedisRepeatedDigitsandisNullishhelpers, the CNH verifier extraction and the removal of top-level allocations that pinned unrelated modules into every bundle (import { isValidCpf }went from 14 KB back to under 700 B).
