Task P.5.1 Implementation Report

Scope

This report documents implementation work completed for task-p.5.1.md.

Focus of this round:

• production hardening for document template management
• metadata separation path from schemaJson
• duplicate version workflow
• stronger template health validation
• improved compare UX
• regression-safe migration support
• test coverage for new hardening helpers

---

Review Inputs

Reviewed before implementation:

• AGENTS.md
• docs/standards/project-foundations.md
• docs/standards/architecture-rules.md
• docs/standards/task-catalog.md
• docs/implementation/task-p.5-implementation.md
• docs/implementation/task-p.5-verification-report.md

Implementation Summary

1. Metadata separation foundation

Added dedicated metadata_json support for document template versions:

• src/db/schema.ts
• drizzle/0006_lazy_shiver_man.sql

Migration behavior:

• add metadata_json
• backfill legacy __templateManagement from schema_json into metadata_json
• scrub embedded metadata from schema_json

Compatibility helper added in:

• metadata.ts

This helper now:

• reads dedicated metadata first
• falls back to legacy metadata inside schemaJson
• sanitizes exported schema so PDFMe JSON stays clean

2. Document template server hardening

Updated template server foundation in:

• service.ts
• management-service.ts

Key changes:

• sanitize schemaJson on create and update
• store lifecycle metadata in metadataJson
• preserve legacy metadata compatibility on read
• duplicate version support with cloned mappings and table columns
• stronger validation output with structured health issues
• compare output expanded with:
  • field/schema changes
  • mapping difference payload
  • validation state for both versions
  • basic JSON diff summary

3. Duplicate-as-draft workflow

Added explicit duplicate action:

• src/app/api/crm/settings/document-templates/versions/[id]/duplicate/route.ts

Client and mutation support updated in:

• service.ts
• mutations.ts

Behavior implemented:

• duplicate any source version into a new draft
• copy schema JSON
• copy mappings
• copy mapping columns
• clear active lifecycle state
• generate a unique draft/copy version label

4. Compare UX improvement

Rebuilt comparison dialog in:

• template-version-management-panel.tsx

Compare UI now shows tabs for:

• metadata
• placeholders
• mappings
• schema
• health

This replaces the earlier toast-only compare result.

5. Validation and health output

Extended validation contract in:

• types.ts

New validation output includes:

• healthStatus
• structured issues
• orphanMappings
• unsupportedSchemaTypes
• sectionMarkerIssues
• suggested next step

6. Audit utility relocation

Moved reusable audit helpers into runtime code space:

• src/features/foundation/pdf-audit/server/shared.ts

Script shim now re-exports from:

• scripts/pdf-audit-utils.ts

This removes direct runtime imports from scripts/.

7. Automated tests added

Added focused tests for hardening helpers:

• metadata.test.ts
• service.test.ts

Covered:

• legacy metadata extraction
• schema sanitization
• metadata merge precedence
• duplicate version label generation

---

Generated Verification Artifacts

Verification commands updated existing generated outputs:

• docs/implementation/pdf-audit-report.json
• docs/implementation/pdf-audit-report.md
• artifacts/pdf-audit/summary.json
• artifacts/pdf-audit/summary.md

These were not hand-edited as part of feature logic. They are generated by verification runs.

---

Known Gaps After This Round

• Turbopack warning still persists during npm run build, even though runtime no longer imports from scripts/ directly.
• Full route-level management tests were not added yet.
• Minimal browser/E2E verification was not added yet.
• audit:pdf still reports an existing active template schema drift for ALLA product template data in the current database state.

---

Outcome

P.5.1 significantly improved the production-readiness of the document template management foundation, especially around metadata handling, draft duplication, health reporting, and compare usability, while keeping the PDF runtime path unchanged.
