## SelectionStepState
TypedDict for Phase 1 workflow state. Provides type safety for the state
structure used by the selection step.
------------------------------------------------------------------------
source
### SelectionStepState
``` python
def SelectionStepState(
args:VAR_POSITIONAL, kwargs:VAR_KEYWORD
):
```
*State for Phase 1: Source Selection & Ordering.*
## SelectionUrls
URL bundle for Phase 1 selection handlers and renderers. All fields
default to empty strings for safe construction before routes are
registered.
------------------------------------------------------------------------
source
### SelectionUrls
``` python
def SelectionUrls(
add:str='', remove:str='', toggle:str='', reorder:str='', clear:str='', select_all:str='', preview:str='',
toggle_focused:str='', keyboard_reorder:str='', filter:str='', grouping_change:str='', browse_directory:str='',
add_external:str='', remove_external:str='', tab_switch:str=''
)->None:
```
*URL bundle for Phase 1 selection route handlers and renderers.*
------------------------------------------------------------------------
source
### SelectionResult
``` python
def SelectionResult(
routers:List, urls:SelectionUrls=, routes:Dict=, render_local_files_panel:Optional=None,
sb_state:Any=None, restore_state:Callable=_no_op_restore, reset_state:Callable=_no_op_reset
)->None:
```
*Return type from init_selection_routers.*
------------------------------------------------------------------------
source
### LocalFilesResult
``` python
def LocalFilesResult(
routers:List, routes:Dict, render_panel:Callable, restore_state:Callable=_no_op_restore,
reset_state:Callable=_no_op_reset
)->None:
```
*Return type from init_local_files_router.*
## Router Result Types
Dataclass return types for router initialization functions. Using
dataclasses instead of tuples makes future additions non-breaking — new
fields with defaults don’t affect existing callers.
