NAME

PAX::Compatibility - compatibility comparator for native-versus-Perl behavior

SYNOPSIS

use PAX::Compatibility;

my $obj = PAX::Compatibility->new(...);
my $result = $obj->report(...);

DESCRIPTION

Runs side-by-side comparisons between stock Perl execution and PAX-managed execution so command-level regressions can be explained instead of guessed at.

METHODS

new, report

These are the public entrypoints exposed by this module's current interface.

PURPOSE

This module exists to keep the compatibility comparator for native-versus-Perl behavior logic in one place so the CLI, build pipeline, and runtime can reuse the same behavior instead of duplicating it.

WHY IT EXISTS

PAX uses this module when it needs compatibility comparator for native-versus-Perl behavior. Keeping that behavior isolated here makes the surrounding compiler and packaging stages easier to reason about and safer to evolve.

WHEN TO USE

Edit this file when a change affects compatibility comparator for native-versus-Perl behavior, the data contract this module returns, or the conditions under which callers choose this path.

HOW TO USE

Load the module through the normal PAX call path, pass explicit arguments rather than ambient global state, and keep project-specific behavior out of this file so the implementation stays neutral across arbitrary Perl applications.

WHAT USES IT

This module is used by the PAX CLI, the build pipeline, standalone packaging, and the test suite paths that cover compatibility comparator for native-versus-Perl behavior.

EXAMPLES

Example 1:

perl -Ilib -MPAX::Compatibility -e 1

Confirm that the module loads from a source checkout.

Example 2:

prove -lr t

Run the repository test suite after changing the behavior this module owns.
