ObjectState 4.0.0 (OpenHCSDev/ObjectState#56) makes the state registered at the global scope the one holder of the global config: an edit of that state is the live global config, mark_saved is the saved one, restore_saved and a checkpoint restore put both back. Everything the config window did to keep the old stores in step with the state is therefore derived, and is deleted.

Deleted from pyqt_reactive.windows.config_window, with the reason

Deleted	Reason
ConfigEditSession.apply_code_edit_context (wrote the live store on a code edit)	derived: the next line applies the code edit to the form, which edits the state
GlobalConfigContextCheckpoint, capture_global_context, restore_global_context (store captured and put back beside the state checkpoint in save_config)	derived: ObjectStateTransactionCheckpoint.restore(state) restores the global state
publish_saved_global_config (saved and live writes after mark_saved)	derived: mark_saved is the save
restore_global_context_if_dirty, _original_live_global_config (live store put back on cancel)	derived: the restore policy calls restore_saved on the state
global_context_dirty, mark_global_field_changed and its parameter_changed connection	unused once the two above are gone (only they read the flag)
saving, begin_save_callback, end_save_callback	unused: only guarded mark_global_field_changed
is_global_config	unused after the above
ConfigWindow._apply_config_from_code_document	forwarding: it only called CodeEditorFormUpdater.update_form_from_instance

No other caller of the removed ObjectState names in src (grep for every removed name); tests/test_provenance_navigation.py renames set_global_config_for_editing to set_global_config.

Test

tests/test_config_window.py::test_global_config_follows_the_window_through_edit_cancel_save_and_failed_save: through a window on the registered global state, a code edit, a cancel, a save the participant refuses and a save move the live and the saved global config and what a registered descendant inherits, with nothing but the state.

Callers

Removed public members of ConfigEditSession, so this is 0.8.0. OpenHCS tests/unit/pyqt_gui/test_config_window_transaction.py uses several of them (listed for the OpenHCS bump). Behaviour: a window whose global-config state is not registered at the global scope no longer changes the global config.

Requires objectstate>=4.0.0,<5, formbridge>=0.1.4,<0.2. Full suite in a fresh venv with both from PyPI: 594 passed, 1 skipped. Ruff fatal checks and the added-lines check pass.
