F. RBAC Checks - Permission matrix and enforcement points
G. Audit Events - 5 event types with metadata
H. Test Checklist - 13 comprehensive test cases covering all workflows

Summary Statistics

Category	Count	Lines
Database	1 file	~50
Validation	1 file	~150
API Endpoints	5 files	~614
UI Components	3 files	~1,350
Documentation	1 file	~950
Total	11 files	~3,114

Key Design Decisions

Versioning Model: Published templates are immutable; editing creates new draft version via duplicate+publish pattern
JSON Storage: Template schema stored as TEXT (JSON string) for flexibility and future custom templates
Validation Separation: Draft saves allow partial state; publish enforces strict validation
Question Types: Support rating_1_5, yes_no, short_text, long_text with conditional comments
Backward Compatibility: W7/W8 can operate with or without templateId (defaults to built-in if null)
RBAC: Admin-only access (no HR read-only for W9, can add in future)
Audit Logging: 5 event types with non-blocking logging

What's Next

To use W9 in production:

Run migration: npx prisma migrate dev --name add_evaluation_templates
Test all 13 test cases in /docs/W9-IMPLEMENTATION.md
Deploy to staging/production
Start building W10 (SMO decision workflow)

W10 will:

Allow SMO to view submitted evaluations
Create final decision workflow
Select published templates for candidates
Assign templates to roles/positions
