# handlers
## Initialize Handler
Fetches VAD data from the alignment service and stores in state.
------------------------------------------------------------------------
source
### AlignInitResult
``` python
def AlignInitResult(
args:VAR_POSITIONAL, kwargs:VAR_KEYWORD
):
```
*Result from pure alignment init handler.*
Contains domain-specific data for the combined layer wrapper to use when
building cross-domain OOB elements (shared chrome, alignment status).
## Router Initialization
Creates the workflow router with the init route.
------------------------------------------------------------------------
source
### init_workflow_router
``` python
def init_workflow_router(
state_store:SQLiteWorkflowStateStore, # The workflow state store
workflow_id:str, # The workflow identifier
source_service:SourceService, # Service for fetching source blocks
alignment_service:AlignmentService, # Service for VAD analysis
prefix:str, # Route prefix (e.g., "/workflow/align/workflow")
urls:AlignmentUrls, # URL bundle (populated after routes defined)
handler_init:Callable=None, # Optional wrapped init handler
)->Tuple: # (router, route_dict)
```
*Initialize workflow routes for alignment.*
Accepts optional handler override for wrapping with cross-domain
coordination (e.g., shared chrome, alignment status OOB updates).
