# tooling/godot-cold-parse [--run-menu] — cold-cache headless parse check.
#
# Used by /pr-process step 1c before push. Deletes the cached script-class
# registry so the parse simulates the cold-start ordering CI / fresh clones
# see: Sprint 36 close caught a new `class_name MetaScreen` base class and
# six extending scripts that parsed fine on warm developer caches but hit
# `Could not find base class "MetaScreen"` post-merge, because the
# autoload-vs-class_name registration order only resolves correctly once the
# class cache is seeded (see CLAUDE.md -> GDScript conventions -> Autoload
# parse-order rule).
#
# Godot's resource scanner emits category errors (e.g. "Export type can only
# be built-in, a resource, a node, or an enum") that do NOT always prefix
# with SCRIPT ERROR — they appear as plain ERROR lines. The filter below
# catches both, then drops known pre-existing noise from the autoload
# class_name parse-order trap. Sprint 36 shipped a scanner error the old
# narrower grep missed; this is why the filter stays wide.
#
# --run-menu: also launch main_menu.tscn briefly (for branches with UI changes).
#
# Exit 0 + "clean" if no matches. Exit 1 + the matched lines if any are found.
