VKC Docgen Template Engine (P1)

Goal

Generate official-form PDFs (starting with unified application + international student part-time work package) from:

• template schema (wizard fields/steps/i18n labels)
• renderSpec (PDF mapping)
• deterministic generator + storage history

Non‑negotiable

• Templates are data-driven:
  • template schema and renderSpec stored in DB (versioned)
  • code is a stable renderer/evaluator

Core data model (minimum)

• document_templates: (docType, purpose, version, schemaJson, renderSpecJson, isActive)
• generated_documents: history + filePath + normalizedFieldsJson + timestamps
• Storage: Supabase private bucket + signed URL download

Schemas / specs

• Template schema JSON:
  • .codex/skills/vkc-docgen-template-engine/references/template-schema.json
• PDF renderSpec reference:
  • .codex/skills/vkc-docgen-template-engine/references/pdf-render-spec.md

Integration points

• UI uses WizardKit and drives fields from schemaJson.
• API route POST /api/documents/generate:
  • auth + 1/day limit
  • load active template
  • validate payload
  • render PDF
  • upload to private storage
  • save history row

STEP3 templates (SoT)

• Official originals + file IDs: docs/STEP3_SOT_RESOURCES.md
• v1 doc types
  • docgen_unified: 통합신청서(신고서)
  • docgen_parttime: 유학생 시간제취업 패키지(시간제취업확인서 + 조건부 요건 준수 확인서 + 통합신청서 선택 포함)
