=head1 NAME

App::karr - Kanban Assignment & Responsibility Registry

=head1 VERSION

version 0.301

=head1 SYNOPSIS

    karr init --name "My Project"
    karr create "Fix login bug" --priority high
    karr list --status todo,in-progress
    karr board
    karr set-refs superpowers/spec/1234.md draft ready
    karr get-refs superpowers/spec/1234.md

=head1 DESCRIPTION

L<App::karr> is the central module behind the L<karr> command line client. The
distribution manages a Git-native kanban board stored in C<refs/karr/*>, where
task cards are Markdown payloads and board configuration is sparse YAML kept in
refs rather than in checked-in work tree files.

The distribution is intended for repositories that want Git to remain the
transport and source of truth. Commands materialize a temporary board view only
for the lifetime of a command, then serialize changes back into refs and push
them onward. This keeps the repository free of a persistent F<karr/> board tree
and avoids ordinary file-level merge conflicts for shared task state.

This module gives the architectural overview. If you want day-to-day command
usage, command groups, and command-by-command navigation, start with L<karr>.

=head1 ARCHITECTURE

=over 4

=item * C<refs/karr/config>

Sparse board configuration overrides layered onto code defaults from
L<App::karr::Config>.

=item * C<refs/karr/meta/next-id>

Dedicated metadata ref for numeric id allocation.

=item * C<refs/karr/tasks/*/data>

Task payloads stored in the same Markdown plus YAML frontmatter shape used by
L<App::karr::Task>.

=item * C<refs/karr/log/*>

Append-style activity log entries written as per-agent JSON lines.

=back

L<App::karr::Git> provides the low-level Git ref operations, while
L<App::karr::BoardStore> handles the higher-level board model: merged config,
task loading, materialization, serialization, snapshots, and restore.

=head1 CLI ENTRY POINT

The installed executable is L<karr>. Running C<karr> without a subcommand shows
the board summary by default, and the command-specific modules under
C<App::karr::Cmd::*> implement the individual operations.

Use L<karr> when you want to learn:

=over 4

=item * which command to run for a task

=item * how backup, restore, destroy, and helper refs fit together

=item * which module implements each subcommand

=item * how to use the Docker-wrapped CLI day to day

=back

=head1 DOCKER RUNTIME

Perl installation remains the normal development path, but Docker is a
first-class runtime option for vendoring C<karr> into other repositories or
tooling environments.

The default C<raudssus/karr:latest> image starts as root only long enough to
inspect the mounted F</work> directory and then drops to the matching numeric
uid and gid before running C<karr>. This prevents root-owned project files when
the image is used through a shell alias. The companion C<raudssus/karr:user>
image is the fixed-user variant for environments that prefer a predictable
non-root runtime without that auto-adjustment.

See L<karr> and F<README.md> for the shell alias form and operator-focused
examples.

=head1 PROGRAMMATIC USAGE

Although the distribution is centered on the CLI, the lower-level modules are
usable from Perl when you want to inspect or manipulate board refs directly.

Reading the current board state:

    use App::karr::Git;
    use App::karr::BoardStore;

    my $git = App::karr::Git->new(dir => '.');
    my $store = App::karr::BoardStore->new(git => $git);

    my $config = $store->load_config;
    my @tasks  = $store->load_tasks;

Creating a task and writing it back:

    use App::karr::Task;

    my $id = $store->allocate_next_id;
    my $task = App::karr::Task->new(
      id       => $id,
      title    => 'Document the release process',
      status   => 'backlog',
      priority => 'high',
    );

    $store->save_task($task);
    $git->push;

Taking a full board snapshot for export logic:

    my $snapshot = $store->snapshot;

These modules are more appropriate for Perl automation than instantiating
L<App::karr> itself, which mainly exists as the MooX::Cmd dispatcher for the
CLI.

=head1 BOARD DISCOVERY

Most commands automatically search upward from the current directory for a Git
repository that contains C<refs/karr/*>. The global C<--dir> option overrides
the starting directory used for that repository discovery.

=head1 DEFAULT BEHAVIOUR

Running C<karr> without a subcommand shows the board summary, which makes the
tool convenient as a quick project status command.
