📝 Walkthrough

Walkthrough

The PR replaces the placeholder gem with a configurable BrUtils façade for CPF and CNPJ utilities. It adds namespace exports, structured errors, RSpec coverage, English and Portuguese documentation, dependency constraints, and a 1.0.0 changelog entry.

Changes

Unified BrUtils façade

Layer / File(s) Summary
Façade configuration and resource access
packages/br-utilities/src/br-utilities.rb, packages/br-utilities/src/br-utilities/br_utils.rb, packages/br-utilities/br-utilities.gemspec, packages/br-utilities/Gemfile
BrUtils is now a configurable class with CPF/CNPJ resources, setters, class helpers, and a mutable DEFAULT instance. Dependency versions are constrained.
Exports and API errors
packages/br-utilities/src/br-utilities/errors.rb, packages/br-utilities/src/br-utilities/cpf_*, packages/br-utilities/src/br-utilities/cnpj_*, packages/br-utilities/src/br-utilities/version.rb
CPF and CNPJ modules, classes, options, and errors are re-exported under BrUtils. New API misuse errors preserve native Ruby exception ancestry.
CPF and CNPJ operation coverage
packages/br-utilities/tests/br_utils.spec.rb
Tests cover initialization, resource mutation, formatting, generation, validation, option forwarding, deterministic generation, formatted inputs, and alphanumeric CNPJ behavior.
Usage and release documentation
README.md, README.pt.md, packages/br-utilities/README.md, packages/br-utilities/README.pt.md, packages/br-utilities/CHANGELOG.md
Documentation covers installation, APIs, configuration, exports, errors, bundled packages, contribution, licensing, and the 1.0.0 release.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to d1717

This PR adds the CPF utilities package and related documentation without any supplied evidence of a concrete correctness, security, availability, or deployment risk; no actionable merge-blocking risk remains.

Poem

A rabbit checks each CPF,
Then hops through CNPJ too.
BrUtils joins the tools,
With defaults ready to use.
Tests watch every path,
While release notes shine anew.

Inline comments:
In `@packages/br-utilities/README.md`:
- Around line 607-616: Update packages/br-utilities/README.md lines 607-616 and
packages/br-utilities/README.pt.md lines 600-609 to replace the undefined
BrUtils::DomainError rescue with a real bundled-package DomainError example.
Expand packages/br-utilities/README.md lines 641-652 and
packages/br-utilities/README.pt.md lines 634-645 with every propagated leaf,
including callback-delivered InvalidLengthError, documenting each in the
required order with its full hierarchy, marker, category, trigger, example, and
handling guidance.
- Line 26: Correct the façade wording to describe BrUtils.cpf and BrUtils.cnpj
as delegating to BrUtils::DEFAULT.cpf and BrUtils::DEFAULT.cnpj, not aliasing
the BrUtils::DEFAULT object. Apply the equivalent precise Portuguese wording in
packages/br-utilities/README.pt.md (line 19) and README.pt.md (line 19), and
update the same contract wording in packages/br-utilities/README.md (line 26),
README.md (line 26), and packages/br-utilities/CHANGELOG.md (line 11).

In `@packages/br-utilities/src/br-utilities/errors.rb`:
- Around line 4-8: Update the exposed sibling error marker modules, including
CpfFmt::Error and CnpjFmt::Error, to include BrUtils::Error so their derived
errors are caught by rescue BrUtils::Error. Add a rescue test covering a
propagated domain error such as CpfFmt::OutOfRangeError or
CnpjFmt::ValidationError.

In `@packages/br-utilities/src/br-utilities/version.rb`:
- Around line 3-6: The BrUtils constant is declared with conflicting module and
class kinds. In packages/br-utilities/src/br-utilities/version.rb lines 3-6,
declare BrUtils as a class and update the placeholder comment; keep the class
reopening in packages/br-utilities/src/br-utilities/br_utils.rb lines 37-42, and
align the BrUtils reopenings in
packages/br-utilities/src/br-utilities/cpf_gen.rb line 3, cpf_utils.rb line 3,
and cpf_val.rb line 3 with that class declaration.

In `@packages/br-utilities/tests/br_utils.spec.rb`:
- Around line 605-633: Add examples for the two documented BrUtils#initialize
contracts in the existing settings contexts: verify string-keyed settings are
normalized and adopt the provided CpfUtils/CnpjUtils instances, and verify
matching nested :cpf or :cnpj settings take precedence over flat keyword values.
Use the existing Helpers.normalize_settings behavior and preserve the current
non-Hash error coverage.

In `@README.md`:
- Around line 10-12: Add the blockquote marker to the blank line between callout
paragraphs in README.md lines 10-12, README.pt.md lines 3-5,
packages/br-utilities/README.md lines 10-12, and
packages/br-utilities/README.pt.md lines 3-5, keeping each callout in one
continuous blockquote.
- Line 239: Update repository-root documentation links to use package-relative
paths: in README.md (239-239) point CPF to packages/cpf-utilities/README.md,
(302-302) CNPJ to packages/cnpj-utilities/README.md, (471-471) both
bundled-package links, (643-643) both propagated-package links, (683-684) both
table links, and (703-703) the changelog to packages/br-utilities/CHANGELOG.md;
apply the corresponding README.pt.md paths at 232-232, 295-295, 464-464,
636-636, 670-670, and 676-677, with the changelog at 696-696 pointing to
packages/br-utilities/CHANGELOG.md.
