description	Document template custom fields: field definitions, document values, merge-at-read, orphan retention, and template editor flows. Use when designing or implementing template fields, document forms, related SQLite schema, or projectContent IPC.

Document template custom fields

Canonical documentation

• Design (not yet in shipped schema; live max v9; next custom-fields migration v10+): docs/database/templateCustomFields.md
• Shipped schema: docs/database/projectDB.md — same commit when migrations/IPC land
• Index: docs/database/README.md

Design summary

• Template shell — existing document_templates
• Field definitions — planned template_fields (UUID field_id, soft-delete, sort, type, config)
• Document values — planned document_field_values + field-scoped link tables
• Orphans — values for inactive/removed defs stay in DB; UI shows active fields only
• Read — active defs + all values; bind by field_id
• Save — validate active defs; upsert; never auto-delete orphans

Implementation phases (short)

1. Schema v10+ — DDL + migrate wiring → projectDB.md
2. Main persist — projectDbContent/*
3. Zod — src-electron/shared/faProjectTemplateField*, faProjectDocumentField*
4. IPC + preload — bridge + projectContentAPI.ts
5. Types — types/I_faProject*Domain.ts
6. Renderer — Pinia, document editor merge/save
7. Template editor UI — field CRUD, type-change guards
8. Deferred — orphan recovery UI, cross-field search, version pins

Do not

• Hard-delete document values when field removed from template
• Key values by label/slug/sort order — field_id only
• Silently change field type + coerce values
• Ship template versioning / per-document version pins in v1
• Store custom field data in electron-store or project_data KV

Types

Shared types → types/. See types-folder.mdc.
