W9 Implementation: Evaluation Template Management (Versioned)

Status: ✅ Complete (Backend + UI + Database + Documentation) Version: 1.0 Date: January 23, 2026

A. Summary

Implement an admin-only evaluation template management system enabling:

CRUD operations on draft templates
Versioning: Publishing locks a template; editing published templates creates new draft versions
Template builder with metadata, stage configuration (HR_SCREENING, MANAGER_REVIEW), categories, and questions
Question types: rating_1_5, yes_no, short_text, long_text with conditional comment requirements
Quick screen support: Optional subset of questions for fast evaluations
Backward compatibility: W7/W8 can continue using default templates or published templates by ID

Design Principle: Templates are immutable once published (copy-on-edit pattern for versions)

B. Routes

UI Pages

Location: /admin/templates (Admin only)
Views:
- List view (table with filters, search, actions)
- Builder view (single template detail with form)

API Endpoints

GET /api/templates
- List all templates with filters (q, status, position)
- Admin only
POST /api/templates
- Create new draft template (v1)
- Admin only
GET /api/templates/:id
- Fetch single template detail
- Admin only
PUT /api/templates/:id
- Update draft template (status must be DRAFT)
- Admin only
- Prevents editing of published/archived templates
POST /api/templates/:id/publish
- Publish draft template or create new version
- Admin only
- Validates schema before publishing
- Sets publishedAt timestamp
POST /api/templates/:id/archive
- Archive published template (status must be PUBLISHED)
- Admin only
- Sets archivedAt timestamp
POST /api/templates/:id/duplicate
- Create new draft copy of any template
- Admin only
- New copy has version 1, status DRAFT

C. Data Model Changes

New Enum: TemplateStatus

enum TemplateStatus {
  DRAFT
  PUBLISHED
  ARCHIVED
}

New Model: EvaluationTemplate

model EvaluationTemplate {
  id                    String                @id @default(cuid())
  name                  String
  appliesToPosition     String
  version               Int                   @default(1)
  status                TemplateStatus        @default(DRAFT)
  schemaJson            String                @db.Text // JSON structure below
  enableQuickScreen     Boolean               @default(false)
  quickQuestionIds      String                @default("[]") @db.Text // JSON array
  createdByUserId       String
  createdByUser         User?                 @relation("TemplateCreatedBy", fields: [createdByUserId], references: [id], onDelete: SetNull)
  publishedAt           DateTime?
  archivedAt            DateTime?
  createdAt             DateTime              @default(now())
  updatedAt             DateTime              @updatedAt
  
  @@index([status])
  @@index([appliesToPosition])
  @@index([publishedAt])
  @@index([createdByUserId])
  @@index([createdAt])
}

Enhanced Models

HrScreening - Add template tracking:

model HrScreening {
  // ... existing fields ...
  templateId            String?
  templateVersion       Int?
  
  @@index([templateId])
}

ManagerReview - Add template tracking:

model ManagerReview {
  // ... existing fields ...
  templateId            String?
  templateVersion       Int?
  
  @@index([templateId])
}

User - Add relation:

model User {
  // ... existing fields ...
  createdTemplates    EvaluationTemplate[] @relation("TemplateCreatedBy")
}

Template Schema JSON Structure

Stored in schemaJson (TEXT field, parsed on read):

{
  stages: [
    {
      stage: "HR_SCREENING" | "MANAGER_REVIEW",
      enabled: boolean,
      categories: [
        {
          id: string,
          name: string,
          description?: string,
          questions: [
            {
              id: string,
              text: string,
              type: "rating_1_5" | "yes_no" | "short_text" | "long_text",
              required: boolean,
              commentRequiredIfRatingBelowOrEqual?: number, // 1-5, only for rating_1_5
              order: number
            }
          ],
          order: number
        }
      ]
    }
  ],
  scoringScale: {
    min: 1,
    max: 5
  }
}
