ln-720-structure-migrator

Type: L2 Domain Coordinator Category: 7XX Project Bootstrap Parent: ln-700-project-bootstrap

Coordinates project restructuring from prototype layout to Clean Architecture.

Purpose & Scope

Aspect	Description
Input	Current project structure, target architecture
Output	Restructured project with Clean Architecture
Workers	ln-721 (frontend), ln-722 (backend), ln-723 (mockdata), ln-724 (replit-cleaner)

Scope boundaries:

Analyzes current project structure
Generates migration plan
Delegates to specialized workers
Verifies final result

Workflow

Phase	Name	Actions	Output
1	Analyze	Scan current structure, detect framework, map files	File inventory
2	Plan	Calculate moves, identify conflicts	Migration plan
3	Execute	Delegate to workers (ln-724, ln-721, ln-722, ln-723)	Restructured project
4	Verify	Run builds, check imports, validate structure	Success report

Delegation Protocol

To ln-724 (Replit Cleanup)

Context:
  projectPath: /project
  skipPreview: false  # Set true for automated pipelines
Options:
  cleanConfigFiles: true      # .replit, replit.nix
  cleanDirectories: true      # .local/, .cache/, .upm/
  cleanPackages: true         # @replit/* from package.json
  cleanViteConfig: true       # Replit imports/plugins
  cleanCodeComments: true     # // @replit annotations
  cleanGitignore: true        # .replit entry

To ln-721 (Frontend)

Context:
  sourcePath: /project/client
  targetPath: /project/src/frontend
  framework: react
  features:
    - ProductPlanning
    - Settings
    - Profile
Options:
  splitMonolithicFiles: true
  extractConstants: true
  extractTypes: true
  createComponentLibrary: true

To ln-722 (Backend)

Context:
  projectName: Kehai
  targetPath: /project/src
  targetFramework: net10.0
  features:
    - ProductPlanning
    - Users
Options:
  createMockData: true
  addSwagger: true
  addHealthChecks: true

To ln-723 (MockData)

Context:
  sourceORM: drizzle
  sourcePath: /project/shared/schema.ts
  targetPath: /project/src/Kehai.Api/MockData
  entities:
    - Epic
    - Story
    - Bet

Critical Rules

Orchestrator Pattern: Analyze and delegate, do not execute transformations directly
Sequential Workers: Execute workers in order (replit-cleanup → frontend → backend → mockdata)
Pre-flight Checks: Verify git status clean, target paths available
No Data Loss: Copy before delete, verify before removing source
Build Verification: Both
```
npm run build
```
and
```
dotnet build
```
must pass
Rollback Ready: Keep backup branch until verification complete

Definition of Done

Current structure analyzed and documented
Migration plan generated
ln-724 completed: Replit artifacts removed
ln-721 completed: Frontend restructured
ln-722 completed: Backend generated
ln-723 completed: MockData migrated
Frontend builds successfully (
```
npm run build
```
)
Backend builds successfully (
```
dotnet build
```
)
No orphan files in old locations
All imports resolve correctly
Migration report generated

Risk Mitigation

Risk	Detection	Mitigation
Uncommitted changes	`git status` not clean	Require clean working directory
Build failure (frontend)	`npm run build` fails	Rollback, delegate to ln-721 for fix
Build failure (backend)	`dotnet build` fails	Rollback, delegate to ln-722 for fix
Lost files	Files missing after migration	Restore from backup branch
Import errors	Module not found	Re-run import update phase
Partial migration	Worker fails mid-execution	Atomic: complete all or rollback all
