Walkthrough

Adds RFC‑822-aware Author decoding/encoding and RSS channel fields (managingEditor, webMaster), expands CI (Windows/Android, broader matrices), improves test data path resolution and cross‑platform line‑ending normalization, adds author parsing tests, bumps Mint tool versions, and adds contributor documentation (CLAUDE.md).

Changes

Cohort / File(s) Change Summary
CI Workflow
​.github/workflows/syndikit.yml
Expanded Ubuntu and macOS matrices (Swift 6.x, Xcode 26.x entries), added build-windows and build-android jobs, unified swift-build to v1.4.2, added PACKAGE_NAME env propagation, adjusted coverage upload flags, and made lint depend on all build jobs.
Author decoding & encoding
Sources/SyndiKit/Common/Author.swift
Replaced synthesized Codable with explicit public init(from:) and public func encode(to:), added internal RFC822 parsing helper (parseRFC822Author), internal initializer, and CodingKeys to support Atom and RSS formats (name/email/uri extraction and preservation).
RSS channel extensions
Sources/SyndiKit/Formats/Feeds/RSS/RSSChannel.swift
Added two new public optional properties: managingEditor: Author? and webMaster: Author?; updated CodingKeys to include them.
Author parsing tests
Tests/SyndiKitTests/AuthorParsingTests.swift
New comprehensive test suite validating RFC822-style author strings, Atom author elements, whitespace/edge cases, URL parsing for uri, and encode/decode round-trips.
Test data path resolution
Tests/SyndiKitTests/Content.Directories.swift
Converted static let data to a closure static let data: URL = { ... }() that prefers a source-relative Data path if present, otherwise falls back to a working-directory-based Data path (Android-aware runtime check).
Test utilities
Tests/SyndiKitTests/Extensions/String.swift
Added func normalizeLineEndings() -> String to convert CRLF (\r\n) to LF (\n) for cross‑platform comparisons.
Test assertion updates
Tests/SyndiKitTests/RSSCodedTests.swift
Applied normalizeLineEndings() to contentHtml comparisons between JSON and RSS items; added tests for managingEditor and webMaster parsing.
Mint tooling
Mintfile
Bumped tool versions: swift-format 600.0.0 → 602.0.0, SwiftLint 0.58.2 → 0.62.2, periphery 3.0.1 → 3.2.0.
Documentation
CLAUDE.md
New contributor-facing doc describing project overview, architecture, build/test/lint commands, coding standards, tests layout, and CI guidance.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~45 minutes

  • Areas needing extra attention:
    • Sources/SyndiKit/Common/Author.swift — verify decoding/encoding semantics across Atom vs RSS inputs, RFC822 parsing edge cases, and correctness of email/name extraction.
    • Sources/SyndiKit/Formats/Feeds/RSS/RSSChannel.swift — ensure new optional fields fit construction/initialization and any downstream consumers (serialization, diffing).
    • Tests/SyndiKitTests/AuthorParsingTests.swift & Tests/SyndiKitTests/RSSCodedTests.swift — confirm test coverage is accurate and robust for international/edge cases and that line-ending normalization does not mask real differences.
    • .github/workflows/syndikit.yml — validate matrix entries and coverage upload flags for Windows and Android jobs; confirm environment propagation and disk-clean steps are safe.
    • Tests/SyndiKitTests/Content.Directories.swift — confirm fallback logic works in CI containers and Android runners.

Poem

🐰
I nibbled RFC‑822 strings with care,
Pulled names and emails from thin air.
I hopped through CI to Windows and phone,
Found test data paths and normalized home.
Hooray — the feed garden's newly sown! 🥕

13-15: Consider handling standalone CR for comprehensive normalization.

The current implementation normalizes CRLF to LF, which addresses Windows line endings. However, standalone CR (\r) line endings can occur in legacy Mac files or edge cases. For more robust cross-platform normalization, consider replacing CR with LF as well.

🔎 Proposed enhancement for comprehensive line ending normalization
 internal func normalizeLineEndings() -> String {
-  return replacingOccurrences(of: "\r\n", with: "\n")
+  return replacingOccurrences(of: "\r\n", with: "\n")
+    .replacingOccurrences(of: "\r", with: "\n")

🔇 Additional comments (5)
Tests/SyndiKitTests/Content.Directories.swift (1)

11-31: LGTM! Platform-aware test data discovery implemented correctly.

The new approach with runtime existence checking and platform-specific fallback paths is well-designed for cross-platform testing. The source-relative path will work for most environments, while the working directory fallback specifically addresses Android emulator constraints.

Tests/SyndiKitTests/RSSCodedTests.swift (1)

175-176: LGTM! Line ending normalization ensures cross-platform test consistency.

The addition of normalizeLineEndings() to both sides of the contentHtml comparison is correctly implemented and will ensure consistent test results across platforms with different line ending conventions (Windows CRLF vs. Unix LF).

.github/workflows/syndikit.yml (3)

318-353: LGTM! Android CI integration is well-configured.

The Android build job is properly structured with:

  • Disk space cleanup to prevent storage issues during builds
  • Multi-API level testing (28, 33, 34) covering a good range
  • The android-copy-files: Data/ parameter correctly aligns with the test data path resolution changes in Content.Directories.swift
  • Test execution enabled with android-run-tests: true

272-317: LGTM! Windows CI coverage added successfully.

The Windows build job properly covers multiple Swift versions (6.1, 6.2) and Windows runners (2022, 2025), with appropriate coverage upload flags.


17-26: LGTM! Ubuntu matrix expanded with additional Swift versions.

The addition of Swift 6.2 and 6.0, along with the nightly 6.3 build, provides comprehensive Swift version coverage for Ubuntu builds.

## Summary
Enhanced RSS author parsing to properly extract both email addresses and
names from various formats, addressing incomplete parsing that previously
only captured names while leaving email fields nil.

## Changes

### Core Implementation
- **Author.swift**: Added custom Codable implementation with RFC 822 parser
  - Supports "email (name)" format: `podcast@example.com (Jane Doe)`
  - Supports email-only format: `webmaster@example.com`
  - Supports name-only format: `John Doe`
  - Maintains backward compatibility with Atom feeds (structured XML)
  - Added internal initializer for full property control

- **RSSChannel.swift**: Added managingEditor and webMaster properties
  - Both decode using new Author RFC 822 parsing logic
  - Properly extract editorial and technical contact information

### Testing
- **AuthorParsingTests.swift**: Comprehensive unit tests (13 test cases)
  - RFC 822 format variations (email+name, email-only, name-only)
  - Edge cases (whitespace, parentheses, international characters)
  - Backward compatibility (Atom format, public API)
  - Round-trip encoding/decoding validation

- **RSSCodedTests.swift**: Integration tests with real feed data
  - Validates raywenderlich.xml managingEditor parsing
  - Validates news.rss email-only format handling

## Results
- All 66 tests passing (including 13 new author parsing tests)
- Linting compliant (only expected warnings for RSS spec terms)
- Successfully parses author information from existing test feeds

Pull Request Review - v0.6.2

This PR includes three main improvements: enhanced RFC 822 author parsing, comprehensive CI/CD expansion, and cross-platform test reliability improvements. Overall, this is a well-structured PR with excellent test coverage. Here's my detailed review:


✅ Strengths

1. Author Parsing Implementation (Sources/SyndiKit/Common/Author.swift:85-157)

Excellent work on the RFC 822 parser! The implementation correctly handles multiple formats:

  • ✅ RFC 822 format: email@example.com (Display Name)
  • ✅ Email-only: email@example.com
  • ✅ Name-only: Display Name
  • ✅ Backward compatibility with Atom structured format
  • ✅ Edge case handling (whitespace, nested parentheses, international characters)

The custom Codable implementation is well-designed:

  • Smart format detection (keyed container vs single value)
  • Proper fallback chain
  • Good documentation with examples

2. Comprehensive Test Coverage (Tests/SyndiKitTests/AuthorParsingTests.swift)

Outstanding test coverage with 13 test cases covering:

  • RFC 822 format variations
  • Edge cases (empty strings, multiple parentheses)
  • International characters
  • Backward compatibility
  • Round-trip encoding/decoding
  • Public API compatibility

The tests are well-organized with clear MARK sections and descriptive names.

3. Integration Tests (Tests/SyndiKitTests/RSSCodedTests.swift:768-820)

Good addition of integration tests validating real-world feed parsing. Tests verify both managingEditor and webMaster parsing.

4. Cross-Platform Improvements

The Content.Directories fix (Tests/SyndiKitTests/Content.Directories.swift:11-31) intelligently handles different test environments:

  • Source-relative path for macOS/Ubuntu
  • Current working directory fallback for Android
  • Clear comments explaining the rationale

The line-ending normalization (Tests/SyndiKitTests/Extensions/String.swift:13-15, RSSCodedTests.swift:175-176) is a sensible solution for Windows compatibility.

5. CI/CD Expansion (.github/workflows/syndikit.yml)

Impressive platform coverage expansion:

  • ✅ Added Xcode 26.x support (26.0, 26.1, 26.2)
  • ✅ Windows testing (2022, 2025 with Swift 6.1, 6.2)
  • ✅ Android testing (API 28, 33, 34)
  • ✅ Updated to brightdigit/swift-build@v1.4.2
  • ✅ Proper dependency chain (lint waits for all builds)

🔍 Issues & Recommendations

1. Email Validation Missing (Author.swift:141-143)

Medium Priority

The parser treats any string with @ as an email, but doesn't validate the format:

if trimmed.contains("@") {
  // Email-only format
  return (name: trimmed, email: trimmed)
}

Potential issues:

  • Strings like "contact @ company" would be treated as email
  • "john@" or "@example.com" would pass
  • Could lead to invalid email values in the email field

Recommendation:
Consider adding basic email validation or at minimum check for @ with non-whitespace on both sides:

// More robust email detection
let hasValidEmail = trimmed.contains("@") && 
                    !trimmed.starts(with: "@") && 
                    !trimmed.hasSuffix("@") &&
                    trimmed.filter { $0 == "@" }.count == 1

2. Encoding Format Discrepancy (Author.swift:150-156)

Low Priority - Design Question

The encode(to:) method always uses keyed container (Atom format), even when the original was parsed from RFC 822 format:

public func encode(to encoder: any Encoder) throws {
  // Try to preserve format by encoding with keyed container
  var container = encoder.container(keyedBy: CodingKeys.self)
  // ... always encodes as structured XML
}

Impact:

  • Comment says "preserve format" but doesn't actually preserve RSS format
  • RSS <managingEditor>email (name)</managingEditor> → Atom <managingEditor><name>...</name><email>...</email></managingEditor>
  • Round-trip encoding changes the format

Options:

  1. Accept this behavior (Atom format is more structured)
  2. Track original format and preserve it during encoding
  3. Update the comment to be accurate

I'd suggest option #1 or #3. The current behavior is reasonable but the comment is misleading.

3. Missing DocC Documentation (RSSChannel.swift:131-134)

Low Priority

The new managingEditor and webMaster properties lack DocC-style documentation:

/// Email address for person responsible for editorial content.
public let managingEditor: Author?

/// Email address for person responsible for technical issues.
public let webMaster: Author?

According to CLAUDE.md:

When adding public APIs, include DocC-style documentation comments with Topics sections.

Recommendation:
Enhance with proper DocC format:

/// Email address and name for the person responsible for editorial content.
///
/// Parses RFC 822 format like `podcast@example.com (Jane Doe)` or plain email addresses.
///
/// - SeeAlso: `Author`
public let managingEditor: Author?

4. Test Data Validation Missing

Low Priority

The integration tests assume test feeds contain expected data but don't validate if the test data files actually exist or have the expected format:

guard let feed = try? Content.xmlFeeds["raywenderlich"]?.get(),
  let rssFeed = feed as? RSSFeed
else {
  XCTFail("Failed to load raywenderlich feed")
  return
}

Recommendation:
Add a comment or assertion explaining what the test feed should contain, or add a CI check that verifies test data integrity.

5. CI Workflow Concerns

Medium Priority

a) Matrix Size: The CI matrix is now quite large (~50+ job combinations). Consider:

  • Do you need all three Xcode 26.x versions (26.0, 26.1, 26.2)? Usually testing oldest + newest is sufficient
  • This increases CI costs and run times significantly

b) Android Disk Space: Good mitigation with disk cleanup script, but consider if all three API levels (28, 33, 34) are necessary. API 28 + 34 might be sufficient.

c) Nightly Build: Using swiftlang/swift:nightly-6.3-noble will cause intermittent failures. Consider making nightly builds continue-on-error: true.

6. Inconsistent Swift Version Compatibility Pattern

Very Low Priority - Style Nitpick

Some files use:

#if swift(<5.7)
  @preconcurrency import Foundation
#elseif swift(<6.1)
  import Foundation
#else
  public import Foundation
#endif

While AuthorParsingTests.swift uses the same pattern but in test code. This is correct per the CLAUDE.md convention, so no action needed, just noting the consistency is good.


🔒 Security Review

No security concerns identified

  • Input validation could be stricter (see issue [skip ci] fixing CI #1), but this is a parsing library, not a validation library
  • No SQL injection, XSS, or other OWASP top 10 vulnerabilities
  • No credential exposure
  • Proper escaping in XML encoding

⚡ Performance Considerations

No significant performance concerns

  • The RFC 822 parser is O(n) with minimal allocations
  • String operations are efficient (single pass)
  • No recursive calls or exponential algorithms

Minor optimization opportunity:
The parser does 2-3 string trims in some paths. Could be optimized to trim once, but the impact is negligible for feed parsing.


📊 Code Quality

Adherence to CLAUDE.md Standards

Excellent compliance:

  • ✅ Swift version compatibility pattern followed
  • ✅ File length within limits (Author.swift: 157 lines << 225 warning)
  • ✅ Function body length acceptable (parseRFC822Author: 34 lines < 50 limit)
  • ✅ Line length at 90 chars (could verify with linting)
  • ✅ Explicit ACL modifiers used (public, internal, private)
  • ✅ Proper MARK: comments in tests

Minor note:

  • Author.swift has cyclomatic complexity that appears acceptable, but the init(from:) has nested conditionals. Currently fine but monitor if adding more format support.

🎯 Overall Assessment

Recommendation: ✅ APPROVE with minor suggestions

This is a well-crafted PR that:

  • ✅ Solves a real problem (incomplete RFC 822 author parsing)
  • ✅ Has excellent test coverage (13 unit tests + 2 integration tests)
  • ✅ Maintains backward compatibility
  • ✅ Significantly expands CI/CD coverage
  • ✅ Follows project conventions and coding standards
  • ✅ Includes proper documentation (CLAUDE.md)

The issues identified are minor and mostly suggestions for improvement rather than blockers:

  1. Email validation (medium priority - can be addressed in future PR)
  2. Encoding comment accuracy (low priority - trivial fix)
  3. DocC documentation (low priority - good practice)
  4. CI optimization (optional - cost/time tradeoff)

Suggested Actions:

  1. Consider adding basic email validation (Issue [skip ci] fixing CI #1)
  2. Update encoding comment to match actual behavior (Issue Update arm.yml #2)
  3. Add DocC documentation for new properties (Issue Feature/spm prep #3)
  4. Consider reducing CI matrix size to optimize costs (Issue Feature/refactory #5)

Great work overall! 🎉

⚠️ Issues & Recommendations

1. Critical: Missing Email Validation in Author Parsing

Location: Author.swift:141-143

// No parentheses found - check if it looks like an email
if trimmed.contains("@") {
  // Email-only format
  return (name: trimmed, email: trimmed)
}

Problem: The contains("@") check is too simplistic. Strings like "Contact us @ example" or "user@@invalid" would be incorrectly treated as valid emails.

Recommendation:

// More robust email detection
if trimmed.contains("@"), trimmed.contains("."), !trimmed.contains(" ") {
  return (name: trimmed, email: trimmed)
}

Or better yet, use a proper email regex or validation function.

Severity: Medium - Could cause incorrect parsing of malformed data


2. Potential Issue: Silent Decoding Failures

Location: Author.swift:87-94

if let keyedContainer = try? decoder.container(
  keyedBy: CodingKeys.self
),
  let decodedName = try? keyedContainer.decode(
    String.self,
    forKey: .name
  )

Problem: Using try? suppresses all decoding errors, making debugging difficult. If Atom format decoding fails for unexpected reasons, it silently falls back to RSS format.

Recommendation: Consider logging or differentiating between "no keyed container available" vs "decoding failed unexpectedly":

if let keyedContainer = try? decoder.container(keyedBy: CodingKeys.self) {
  do {
    let decodedName = try keyedContainer.decode(String.self, forKey: .name)
    // Atom format handling...
  } catch {
    // Log unexpected decoding error before falling back
  }
}

Severity: Low - Mainly affects debuggability


3. Missing Test Case: Malformed RFC 822 Format

Location: Tests/SyndiKitTests/AuthorParsingTests.swift

Missing test cases:

  • email@example.com ( - Unclosed parenthesis
  • (Name Only) - Parentheses without email
  • email@example.com (Name) extra text - Text after closing parenthesis
  • multiple@test.com @domains.com - Multiple @ symbols

Recommendation: Add edge case tests to verify behavior with malformed input.

Severity: Low - Good defensive programming practice


4. Code Organization: Large Test File

Location: AuthorParsingTests.swift (250 lines)

Issue: While well-organized with MARK comments, the file approaches SwiftLint's warning threshold (225 lines).

Recommendation: Consider splitting if more tests are added:

  • AuthorRFC822ParsingTests.swift
  • AuthorAtomParsingTests.swift
  • AuthorEncodingTests.swift

Severity: Very Low - Preventive maintenance


5. Performance: Repeated Decoder Creation in Tests

Location: AuthorParsingTests.swift (multiple locations)

let decoder = XMLCoder.XMLDecoder()
let author = try decoder.decode(Author.self, from: Data(xml.utf8))

Issue: Each test creates a new decoder instance. While XMLDecoder initialization is fast, reusing a shared decoder would be more efficient.

Recommendation:

final class AuthorParsingTests: XCTestCase {
  private let decoder = XMLCoder.XMLDecoder()
  
  func testAuthorWithEmailAndName() throws {
    // Use self.decoder
  }
}

Severity: Very Low - Micro-optimization


6. Documentation: Missing RSSChannel Field Documentation

Location: RSSChannel.swift:131-135

/// Email address for person responsible for editorial content.
public let managingEditor: Author?

/// Email address for person responsible for technical issues.
public let webMaster: Author?

Issue: Comments say "Email address" but the type is Author? which includes name, email, and URI.

Recommendation:

/// Person responsible for editorial content. Parsed from RFC 822 format.
public let managingEditor: Author?

/// Person responsible for technical issues. Parsed from RFC 822 format.
public let webMaster: Author?

Severity: Very Low - Documentation accuracy


🔒 Security Review

No security concerns identified

  • Input validation is appropriate for RSS/Atom parsing
  • No SQL injection, XSS, or command injection vectors
  • Proper handling of user-controlled strings
  • No sensitive data exposure

📊 Test Coverage Assessment

Excellent coverage for Author parsing:

  • ✅ RFC 822 format variations
  • ✅ Atom format backward compatibility
  • ✅ Edge cases (empty strings, whitespace, international characters)
  • ✅ Round-trip encoding/decoding
  • ✅ API compatibility

Recommendation: Consider adding integration tests that verify managingEditor and webMaster fields parse correctly in real RSS feeds.


🚀 Performance Considerations

No performance issues identified

  • String parsing is efficient (single-pass with String slicing)
  • Decoder fallback pattern is appropriate
  • Test data directory lookup uses lazy initialization

📝 Code Quality & Style

Adheres to project conventions:

  • Proper Swift version compatibility guards
  • Follows SwiftLint rules (line length, complexity)
  • Clear MARK comments for organization
  • Consistent naming conventions
  • Proper access control (public/internal)

🎯 Recommendations Summary

Must Fix Before Merge:

  1. ⚠️ Improve email validation in Author.parseRFC822Author (Author.swift:141)

Should Consider:

  1. Add error logging for unexpected decoding failures
  2. Add malformed input test cases
  3. Fix documentation comments for managingEditor/webMaster

Nice to Have:

  1. Split test file if it grows beyond 250 lines
  2. Reuse decoder instances in tests

✅ Final Verdict

Recommendation: Approve with Minor Changes

This is a well-crafted PR with excellent test coverage and important functionality improvements. The author parsing implementation is solid, and the CI/CD enhancements significantly improve platform coverage.

The only blocking issue is the simplistic email validation, which should be strengthened before merge. All other recommendations are minor improvements that can be addressed now or in future PRs.

Great work on maintaining backward compatibility and comprehensive testing! 🎉

72-73: LGTM!

The new CodingKeys entries for managingEditor and webMaster follow the existing pattern and correctly match the RSS 2.0 specification element names.


131-136: LGTM!

The new managingEditor and webMaster properties are correctly typed as optional Author? values with appropriate documentation. This aligns with the RSS 2.0 specification where these fields contain email addresses with optional display names.

Tests/SyndiKitTests/RSSCodedTests.swift (3)

175-176: LGTM!

Applying normalizeLineEndings() symmetrically to both jsonItem.contentHtml and rssItem.contentHtml ensures consistent cross-platform test behavior regardless of line ending differences in source files.


771-789: LGTM!

Good integration test for RFC 822 format parsing. The test validates both name and email extraction from the managingEditor field.


791-819: LGTM!

This test covers the email-only format where name and email are expected to be identical, validating both managingEditor and webMaster parsing.

Tests/SyndiKitTests/AuthorParsingTests.swift (4)

43-59: LGTM!

Comprehensive test suite with good coverage of RFC 822 format parsing, starting with the standard email (Name) pattern.


121-152: LGTM!

Edge case coverage is thorough—empty strings, nested parentheses, and international characters are all tested appropriately.


169-205: LGTM!

Backward compatibility tests for Atom format ensure the new RFC 822 parsing doesn't break existing structured <name>, <email>, <uri> element parsing.


207-249: LGTM!

Round-trip encoding/decoding tests and public initializer compatibility tests ensure the API contract is preserved.

Sources/SyndiKit/Common/Author.swift (4)

38-62: LGTM!

The updated documentation clearly explains the supported formats, and the CodingKeys enum is appropriately scoped as internal.


85-111: LGTM!

The dual-path decoding strategy cleanly handles both Atom (keyed container with child elements) and RSS (single-value RFC 822 string) formats. Using try? for the keyed container attempt and falling back to single-value is idiomatic.


113-148: LGTM!

The RFC 822 parsing logic correctly handles:

  • Standard email (Name) format
  • Nested parentheses via firstIndex/lastIndex
  • Email-only strings (using @ heuristic)
  • Name-only strings

The @ check is a reasonable heuristic for RSS feed author fields.


150-156: Encoding always uses keyed (Atom) format.

The encoder always outputs structured <name>, <email>, <uri> elements. This means RSS-decoded authors will round-trip to Atom format. This is acceptable behavior, but worth noting for consumers who re-encode feeds.

⚠️ Potential issue | 🟡 Minor

Review dependency version updates and test for new SwiftLint rule violations.

Swift-format 602.0.0 is the latest stable release. SwiftLint 0.62.2 requires Swift 6 or higher to build, but the Swift Package Manager plugins work with Swift 5.9 and later. Since you're using Mint for pre-built binaries, the compiler requirement doesn't directly affect your setup.

However, SwiftLint 0.62.2 introduces breaking changes that may require configuration updates:

  • The sorted_imports rule's behavior changed to treat imports directly adjacent to each other as a group, with imports separated by non-import statements or empty lines treated as separate groups
  • A new incompatible_concurrency_annotation rule was added that triggers on declarations isolated to global actors and Sendable constraints
  • A new prefer_asset_symbols rule was added to detect string-based image initialization calls

Periphery 3.2.0 is available and released June 27, 2025. These version bumps are safe, but run your linter checks after updating to ensure no new violations are introduced by the rule behavior changes.

🤖 Prompt for AI Agents
In Mintfile lines 1-3 update, the PR bumps swift-format to 602.0.0, SwiftLint to
0.62.2 and Periphery to 3.2.0; after updating, run the project linting and
static-analysis pipeline locally and in CI, verify SwiftLint 0.62.2 doesn’t
introduce failures, and if it does, update .swiftlint.yml to adapt to changed
rules (adjust sorted_imports grouping, add or configure
incompatible_concurrency_annotation and prefer_asset_symbols rules —
enable/disable or tune severity and exceptions), and re-run tests; also confirm
Periphery 3.2.0 runs cleanly in your analysis step.

* Fix SwiftLint type_contents_order violations across codebase

Reorganize type members to comply with SwiftLint's type_contents_order
rule, which requires specific ordering of type elements (subtypes,
properties, initializers, methods, etc).

Changes:
- OPML+Head.swift: Move CodingKeys enum before properties
- DecodingError.swift: Move Dictionary properties before initializer
- PodcastLocation+GeoURI.swift: Move initializers before static methods
- SiteCollectionDirectory.swift: Move Instance initializer before methods
- SiteLanguageCategory+Site.swift: Ensure CodingKeys enum before properties

All type members now follow the correct order:
1. Subtypes (enums, nested types)
2. Properties
3. Initializers
4. Methods

All tests pass (73/73) and 0 serious linting violations remain.
