=head1 NAME

t/47-zombie-coverage-closure.t

=head1 PURPOSE

Provides isolated regression coverage for the zombie-process fixes that were
hard to exercise reliably inside broader runtime tests.

=head1 WHAT IT TESTS

This test file verifies two narrow internal behaviors:

=over 4

=item *

the runtime helper command probe can recognize a matching internal helper
command string from a helper file body

=item *

the collector loop shutdown path can execute its forced-kill cleanup branch and
still clear the tracked active worker set

=back

=head1 WHY IT EXISTS

The broader runtime and refactor suites carry a lot of setup and monkey-patched
state. These two coverage points are simpler and more reliable when exercised in
their own minimal test file.

=head1 WHEN TO USE

Use this focused regression while changing collector child-reaping behavior,
forced worker shutdown, or the runtime helper command detection code. It is
meant for narrow zombie-fix iterations where the broader runtime suites would
add unnecessary setup noise.

=head1 HOW TO USE

Run it directly while iterating on collector zombie handling or runtime helper
resolution:

  prove -lv t/47-zombie-coverage-closure.t

Run it under coverage when closing the final library coverage gap:

  HARNESS_PERL_SWITCHES=-MDevel::Cover prove -lv t/47-zombie-coverage-closure.t

=head1 EXAMPLES

Direct focused rerun:

  prove -lv t/47-zombie-coverage-closure.t

Covered focused rerun:

  HARNESS_PERL_SWITCHES=-MDevel::Cover prove -lv t/47-zombie-coverage-closure.t

=head1 WHAT USES IT

This file is a focused regression for the collector zombie cleanup and runtime
helper command-detection code paths in
C<Developer::Dashboard::CollectorRunner> and
C<Developer::Dashboard::RuntimeManager>.
