Phase 18 Plan 01: Template Schema and Migration Summary

One-liner: Drizzle document_templates table with 7 columns, nullable JSONB fields, soft-delete via archivedAt, FK to form_templates with no cascade, and auto-generated SQL migration 0012.

Tasks Completed

Task	Name	Commit	Files
1	Add documentTemplates table to schema.ts	9e677f9	teressa-copeland-homes/src/lib/db/schema.ts
2	Generate Drizzle migration	c33c4ec	teressa-copeland-homes/drizzle/0012_ancient_blue_shield.sql

What Was Built

Added the documentTemplates Drizzle table definition to schema.ts immediately after formTemplates. The table has exactly 7 columns per D-02:

• id — TEXT PRIMARY KEY via crypto.randomUUID()
• name — TEXT NOT NULL
• formTemplateId — TEXT NOT NULL, FK to formTemplates.id with no onDelete (D-06)
• signatureFields — JSONB nullable, typed as SignatureFieldData[] (D-04)
• archivedAt — TIMESTAMP nullable, soft-delete sentinel (D-07)
• createdAt — TIMESTAMP NOT NULL DEFAULT NOW()
• updatedAt — TIMESTAMP NOT NULL DEFAULT NOW()

Also added documentTemplatesRelations joining to formTemplates via formTemplateId.

Generated migration 0012_ancient_blue_shield.sql via drizzle-kit generate. The migration contains only a CREATE TABLE statement and an ALTER TABLE ... ADD CONSTRAINT for the FK — no alterations to existing tables.

Verification

• npx tsc --noEmit — zero errors
• ls drizzle/0012_*.sql — exactly one migration file (0012_ancient_blue_shield.sql)
• grep "document_templates" drizzle/0012_ancient_blue_shield.sql — CREATE TABLE present
• grep "form_template_id" drizzle/0012_ancient_blue_shield.sql — FK column present

Deviations from Plan

None — plan executed exactly as written.

Known Stubs

None — this plan is schema-only. No UI or API routes were implemented. Phase 18-02 handles the CRUD API routes.
