1.0.0

First stable 1.0 release. The standard has been reorganized around a clear division of roles, with PHP-CS-Fixer promoted to the primary tool.

Tool roles (breaking)

• PHP-CS-Fixer is now the primary tool. It owns all code formatting (based on PER-CS 3.0) and auto-fixes it. Use the shared config: return Config::create(__DIR__);
• PHP_CodeSniffer is now supplementary. Its ruleset was slimmed by ~50 sniffs: all formatting checks duplicated by PHP-CS-Fixer were removed (the whole PSR12 ruleset, array formatting, whitespace/spacing, string quoting, use-statement ordering, and more). It now focuses on what the fixer cannot express: structural and semantic checks, Laravel conventions, naming, complexity.
• PHP_CodeSniffer alone is no longer a complete standard. Run both tools together (composer cs).

Requirements (breaking)

• PHP ^8.4 (was ^8.3)
• PHP_CodeSniffer ^4.0

Main coding-style changes

• PHP 8.4 modernization: @PHP8x4Migration + @PHP8x4Migration:risky presets enabled (risky rules on by default).
• PHPUnit: @PHPUnit10x0Migration:risky preset; test method names are snake_case (php_unit_method_casing), with the PSR1 CamelCaps sniff excluded for tests/. php_unit_strict is disabled: the assertEquals to assertSame rewrite is delegated to Rector's AssertEqualsToSameRector, which only rewrites provably-scalar assertions and so avoids breaking object and array value comparisons.
• Line length: was a hard 120 error; now 180 warning / 220 error (soft-wrap era).
• Imports: global functions are imported (global_namespace_import), classes and constants stay fully qualified; unneeded import aliases removed.
• PHPDoc: single-line docblocks for constants, properties and methods where they fit (phpdoc_line_span); @inheritdoc normalized to @inheritDoc; noise annotations (@author, @package, @since, ...) stripped; types ordered.
• Class structure: fixed member order enforced (ordered_class_elements); one blank line between methods.
• Modern PHP: is_null() → null ===-free comparisons, cast functions → native casts (modernize_types_casting), and/or → &&/||, heredoc → nowdoc when possible, elvis operator where shorter, native constant/function casing.
• Strings: single quotes by default, no concat spacing ('hello'.$name), mb_* string functions enforced.
• Arrow functions are not forced: long closure syntax stays when more readable (use_arrow_functions disabled).

Developer experience

• composer cs now chains PHP-CS-Fixer and phpcbf, identical locally and in CI.
• Single auto-fix CI workflow replaces the previous two style workflows; it runs Rector, PHP-CS-Fixer and phpcbf, then commits fixes back (copyable example). It now uses stefanzweifel/git-auto-commit-action v7.
• Custom sniffs are now documented in one place, including the previously undocumented Functions.MissingOptionalArgument: docs/README.md
• Rector added to the toolchain (composer rector).

Upgrading from 0.x

1. Bump PHP to 8.4 and this package to 1.0.0.
2. Replace your PHP-CS-Fixer config with Config::create(__DIR__) (see README).
3. Keep <rule ref="IxDFCodingStandard"/> in phpcs.xml; remove any formatting sniff overrides that no longer exist.
4. Run composer cs and review the (large, mostly mechanical) diff.

What's Changed

• Modernize coding standard: PHP 8.4, PER-CS 3, Rector, dedup rules by @alies-dev in #42
• Update stefanzweifel/git-auto-commit-action action to v7 in #44
