# frozen_string_literal: true

#
# Configures (but does not yet activate) the Zeitwerk autoloader. The
# actual `loader.setup` + `loader.eager_load` happens later in {ESM.load!},
# which {ESM.run!} triggers at boot. Tests skip autoload setup entirely.
#
# What's configured here:
#
#   * Inflector overrides for non-standard casing (ESM, XM8, API, JSON).
#   * `collapse` so `lib/esm/model/server.rb` defines `ESM::Server` rather
#     than `ESM::Model::Server`.
#   * `push_dir` for jobs so they're loaded at the root namespace
#     (`SomeJob` rather than `ESM::Jobs::SomeJob`).
#   * `ignore` for everything loaded manually elsewhere (via Loader) or
#     reopened by extensions, plus the `pre_init/` and `post_init/`
#     directories themselves (they're scripts, not class definitions, and
#     would confuse Zeitwerk's file = constant rule).
