# Document Project Workflow Router
<critical>The workflow execution engine is governed by: {project-root}/_bmad/core/tasks/workflow.xml</critical>
<critical>You MUST have already loaded and processed: {project-root}/_bmad/bmm/workflows/document-project/workflow.yaml</critical>
<critical>Communicate all responses in {communication_language}</critical>
<workflow>
<critical>This router determines workflow mode and delegates to specialized sub-workflows</critical>
<step n="1" goal="Check for ability to resume and determine workflow mode">
<action>Check for existing state file at: {project_knowledge}/project-scan-report.json</action>
<check if="project-scan-report.json exists">
<action>Read state file and extract: timestamps, mode, scan_level, current_step, completed_steps, project_classification</action>
<action>Extract cached project_type_id(s) from state file if present</action>
<action>Calculate age of state file (current time - last_updated)</action>
<ask>I found an in-progress workflow state from {{last_updated}}.
**Current Progress:**
- Mode: {{mode}}
- Scan Level: {{scan_level}}
- Completed Steps: {{completed_steps_count}}/{{total_steps}}
- Last Step: {{current_step}}
- Project Type(s): {{cached_project_types}}
Would you like to:
1. **Resume from where we left off** - Continue from step {{current_step}}
2. **Start fresh** - Archive old state and begin new scan
3. **Cancel** - Exit without changes

What would you like to do?
1. **Re-scan entire project** - Update all documentation with latest changes
2. **Deep-dive into specific area** - Generate detailed documentation for a particular feature/module/folder
3. **Cancel** - Keep existing documentation as-is
